Description

lever tensioner

technical field

The utility model belongs to the technical field of machinery and relates to a tensioner, in particular to a lever type tensioner.

Background technique

During the transportation of the goods, it is usually necessary to bind the goods to prevent the goods from falling off or colliding with each other and causing loss or damage. Although the method of directly binding with ropes is very common, it is time-consuming and laborious, and it is difficult to tie the goods tightly. Tensioner is an advanced binding tool. It is convenient and safe to use a tensioner to bind goods, and is very popular among drivers.

Existing tensioners are usually made up of brackets, belt shafts and binding straps. The tape shaft is connected to the bracket and the tape shaft is rotatable, and the binding tape is wound on the tape shaft. A crowbar hole is provided at the outer end of the belt shaft protruding out from the bracket. When the goods need to be bundled, the crowbar is inserted into the crowbar hole, and the belt shaft can be driven to rotate by turning the crowbar. However, every time a certain angle is turned, the crowbar needs to be pulled out and reinserted. Obviously, this makes the binding efficiency inefficient, time-consuming and laborious, and it is difficult to bind the goods tightly.

And above-mentioned tensioner is mainly used in the occasion that the length of bundling strap is relatively long. Some occasions that only need to shorten the binding strap a little make the operation of the above-mentioned tensioner more loaded down with trivial details, and the use effect is not good.

People have designed various tensioners for this reason, such as the "lever tightener" that Chinese patent CN2827932Y provides, it is made up of main rod, U-shaped rod and lock iron etc., main rod is Z-shaped, main rod The inner end of the U-shaped bar is hinged on the U-shaped open end of the U-shaped bar. When the goods need to be tied up, the main bar is moved to make the Z-shaped protrusion of the main bar swing from the upper part of the U-shaped bar to the lower part of the U-shaped bar.

A binding strap is connected to one end of the U-shaped bar, and the other end of the binding strap is connected to a protrusion in the middle of the main rod. When binding the goods, the binding belt connected to the protruding part of the middle part of the main pole will swing to the lower part of the U-shaped pole together.

Although, the above-mentioned patent can tighten the binding belt by pulling the main rod, thereby binding the goods. However, the binding band will enter the U-shaped opening of the U-shaped bar, so that the binding band may be stuck, so that the main bar cannot be reset, which affects the normal use of the tensioner.

Similar problems also exist in other existing tensioners.

Contents of the invention

The purpose of this utility model is to provide a lever-type tensioner with compact structure and easy to use in order to solve the above-mentioned problems in the prior art.

In the aforementioned lever tensioner, the sensor is a tension sensor.

There are the following situations for the hinged connection of connecting rod 1, connecting rod 2 and the handle:

As the first case, in the aforementioned lever tensioner, the first connecting rod is hinged to one side of the handle, and the other side of the handle is hinged to the second connecting rod.

In the process of pulling the handle, the handle can be swung around the hinge of the second connecting rod, and the hinge of the first connecting rod and the handle can be swung from the upper part of the second connecting rod to the lower part of the second connecting rod.

As the second case, in the above-mentioned lever tensioner, the second connecting rod is U-shaped, the inner end of the handle is U-shaped, and one end of the first connecting rod is hinged to the U-shaped opening of the handle. Between, the inner end of the handle is hinged between the U-shaped openings of the second connecting rod.

In the process of swinging the handle, after the handle swings around its hinge on the second connecting rod, the middle part of the handle can be embedded in the U-shaped opening of the second connecting rod, and at the same time, the outer end of the handle is against the second connecting rod, so that the Rod two could not continue the hem. And the hinged part of connecting rod one and handle swings to connecting rod two bottoms this moment, so just makes handle can't reset under the situation that does not apply external force swing handle.

At the same time, after the handle swings, the above-mentioned connecting rod one is embedded in the U-shaped opening at the inner end of the handle.

Compared with the prior art, the lever type tensioner only needs to pull the handle to shorten the distance between the first hook and the second hook, and the handle will not reset without external force after swinging. In this way, the goods that need to be tightened are tightly bound. It can be seen that it is relatively easy to use and has relatively high stability in use.

At the same time, after the handle is pulled, the hinge part in the middle is embedded in the U-shaped notch of the second connecting rod or is located at the lower part of the second connecting rod through the U-shaped notch, and the outer end of the handle is against the upper part of the second connecting rod. It will automatically form a self-locking. Therefore, its structure is relatively simple and compact.

In addition, the sensor can also enable the operator to know the tightening force of the tensioner in time, making the operation of the tensioner more humanized.

Detailed ways

As shown in Fig. 1 and Fig. 2, this lever tensioner is used for binding goods, and it is made up of handle 1, connecting rod one 2, connecting rod two 3, hook one 4 and hook two 5 etc.

As shown in FIG. 3 , the handle 1 is rod-shaped, and the inner end of the handle 1 is U-shaped, and there is a protruding hinge portion 1 a near the inner end of the handle 1 . The second connecting rod 3 is U-shaped, and the inner end of the handle 1 is hinged to the U-shaped opening of the second connecting rod 3 .

One end of the connecting rod one 2 is hinged at the hinge portion 1 a of the handle 1 , and one end of the connecting rod one 2 is located at the U-shaped opening of the handle 1 .

The other end of the connecting rod-2 is provided with a hook-4, and the connecting rod-2 and the hook-4 are movably connected. That is to say, there is a ring-shaped buckle at the other end of the connecting rod-2, and a ring-shaped buckle is also arranged on the hook-4, and a ring-shaped buckle is provided between the connecting rod-2 and the hook-4. The connecting buckle, the hasp on the above-mentioned connecting rod-2 and the hook-4 are all fastened on the connecting buckle.

The other end of the connecting rod two 3 is provided with a hook two 5, and a sensor 6 is arranged between the connecting rod two 3 and the hook two 5, and the sensor 6 is a tension sensor. Connecting rod two 3 is made up of left rod two 3a and right rod two 3b two parts, and the two ends of sensor 6 are fixedly connected with left rod two 3a, right rod two 3b respectively, as shown in Figure 4. Certainly, here left bar two 3a are hinged at handle 1 inner end, and right bar two 3 link with hook two 5.

When this lever tensioner is in the initial state, the hinged portion 1a of the handle 1 is not embedded in the U-shaped opening of the connecting rod 2 3 . When the goods need to be bundled, pull the handle 1 so that the hinge of the handle 1 hinge part 1a and the connecting rod one 2 swings from the top of the connecting rod two 3 to the bottom of the connecting rod two 3 . Of course, the above-mentioned hinged part 1a passes through the U-shaped opening of the second connecting rod 3 .

After the handle 1 swings to a certain position, it will lean against the connecting rod 2 3, so that self-locking is formed. So that the handle 1 cannot be reset without applying external force. Obviously, after the handle 1 swings, the distance between the first hook 4 and the second hook 5 is correspondingly shortened, so that the goods are tightly bound.

At the same time, the tension force of the entire tensioner can be known in time through the sensor, which is convenient for the operator to operate. Of course, according to the actual situation, the sensor 6 can also be arranged between the connecting rod one 2 and the hook one 4 . Correspondingly, the second connecting rod 3 is movably connected with the second hook 5. And connecting rod one 2 is made up of two parts of left rod one and right rod one, and the two ends of sensor 6 are fixedly connected with left rod one and right rod one respectively.

In addition, the first connecting rod 2 is hinged to one side of the handle 1, and the other side of the handle 1 is hinged to the above-mentioned connecting rod two 3. It is also feasible. Of course, in this case, when the hinge between the handle 1 and the connecting rod 1 2 swings from the upper part of the connecting rod 2 3 to the lower part of the connecting rod 2 3, the handle 1 can also lean against the connecting rod 2 3, so that the handle 1 is positioned at this time.
