Abstract

The utility model relates to a ratchet tensioner, which is used for goods bundling and fastening. The self-winding tensioner is characterized in that the two ends of a tensioning belt reel are respectively arranged on reel holes on the left side and the right side of the ratchet bracket and are fixedly connected with the two sides of a ratchet and a handle in sequence; one end of a tensioning belt is fixedly connected with the reel, the tensioning belt is wound to form a coil, and the other exposed end of the tensioning belt is connected with a first drag hook; and the ratchet bracket is connected with a second drag hook. The utility model has the advantages that: due to the integrated design, the ratchet and the reel can rotate clockwise through rotating the handle during operation so as to tightly wind the tensioning belt on the reel, thereby facilitating bundling and fastening goods; the tensioning belt can be unwound through rotating the handle to a certain position and can be easily drawn out through pressing the compression spring on the handle to separate the pawl from the ratchet. Therefore, the use and carrying are both very convenient.

Description

From belt retracted tensioning device

Technical field

The utility model relates to a kind of Goods binding that is used for, the straining ratchet of tightening. relate in particular to the incorporate straining ratchet of a kind of puller strap and straining ratchet.

Background technology

Straining ratchet is the instrument that goods is tightened in logistics department's binding commonly used.The straining ratchet of Shi Yonging is made up of two independently puller strap assemblies separated from one another and ratchet assembly usually in the market.Two parts must be taken into account in use simultaneously, and are indispensable, so practical operation rather inconvenience when using.

The utility model content

The utility model purpose is: provide a kind of puller strap and ratchet rack integral from belt retracted tensioning device, use and carry with convenient.

For achieving the above object, the technical scheme that adopts is: from belt retracted tensioning device, comprise puller strap and ratchet support, first drag hook and second drag hook, it is characterized in that: the spool two ends place the spool hole, left and right side of ratchet support respectively, and are fixedly connected with ratchet, handle two sides successively; Described puller strap places between the left and right side of described ratchet support, and an end is fixedlyed connected with spool, and twines rolling, and the other end that exposes is connected with first drag hook; Two ratchets are equipped with an end of spring, and the base with the ratchet support is connected, and another root and handle join, and the other end of two ratchets joins with the tooth paddy of ratchet respectively, and can rotate flexible with ratchet; Described ratchet support is connected with second drag hook.

One end of described spool is equipped with knob.

Good effect of the present utility model is: from the puller strap and the design of ratchet rack integral of belt retracted tensioning device, turning handle can drive ratchet and the rotation of spool clockwise direction during operation, and puller strap is twisted on the spool tightly, and goods is tightened in convenient binding; Need put when band, only ratchet and ratchet are disengaged, promptly puller strap can be pulled out with pulling drag hook. therefore use and carry all very convenient.

Inboard ratchet of ratchet support and ratchet syndeton schematic diagram among Fig. 3 Fig. 2.

Among the figure, 1-first drag hook; The 2-puller strap; The 3-handle; 4-second drag hook; The 5-knob; 6-ratchet support; The 7-spool; The 8-ratchet; 9,9 '-ratchet; The 10-button.

The specific embodiment

Fig. 1 and Fig. 2 are respectively from belt retracted tensioning device contour structures and ratchet supporting structure schematic diagram, diagram as seen, from belt retracted tensioning device, comprise puller strap 2 and ratchet support 6, first drag hook 1 and second drag hook 4, it is characterized in that: spool 7 two ends place the spool hole, left and right side of ratchet support 6 respectively, and are fixedly connected with ratchet 8, handle 3 both sides successively; Described puller strap 2 places between the left and right side of described ratchet support 6, the groove that puller strap 2 one ends pass in the middle of the spool 6 is fixedlyed connected with spool 6, one end of described spool is equipped with knob, and turning knob 5 drives spool 7 belt tensioner is twined rolling, and the other end that exposes is connected with first drag hook 1; Described ratchet support 6 is connected with second drag hook 4: Fig. 3 shows ratchet support 6 inboard ratchets 8 and ratchet 9 and ratchet 9 ' syndeton schematic diagram, the end that ratchet 9 is equipped with spring is fixedlyed connected with the base of ratchet support 6, one end and the handle 3 of ratchet 9 ' be equipped with spring join, ratchet 9 and ratchet 9 ' the other end with join with the tooth paddy of ratchet 8 respectively, and can rotate with ratchet 8 and stretch.

Fig. 2 and Fig. 3 as seen, ratchet 8 usually can only clockwise direction rotates, counterclockwise because ratchet 9 and ratchet 9 ' prevention ratchet 8 can not rotate.Drive the also clockwise direction rotation of ratchet 8 spools 7 when handle 3 clockwise directions rotate, when described handle 3 counterclockwise returned the original place, ratchet 9 continued to stop ratchet 8 rotation counterclockwise, thereby described handle 3 perseverations reach the purpose of tightening up puller strap 2.Only need when putting band by ratchet 9 ' button 10 on the fixed handle, thereby the compression spring breaks away from ratchet 9 ' retraction and ratchet 8, simultaneously handle 3 is gone to and ratchet 9 same linear positions, because handle 3 two sides connect the curved surface of end, spool 7 place, ratchet 9 and ratchet 8 are also disengaged, therefore can easily pull out puller strap 2 with pulling first drag hook 1 this moment, uses and carry all very convenient.
