Abstract

Disclosed is an anti-loosening strapping tape device. A clutch cam (6) is rotated by means of an operation handle (13), and the clutch cam (6) can enable a buckle plate (8) to overcome a force of action that causes a torsion spring (9) to be locked, so as to realize one-way locking of a ratchet wheel (5) by the buckle plate (8), and realize the disengagement of the buckle plate (8) from the ratchet wheel (5). During use, the clutch cam (6) can be rotated, by rotating the operation handle (13), to the position where the buckle plate (8) is disengaged from the ratchet wheel (5), and in this case, a binding tape (2) can be randomly drawn out under the action of an external force, and can be automatically tightened just by loosening the grip; and the clutch cam (6) is then rotated to the position where the buckle plate (8) locks the ratchet wheel (5), and since the locking performed on the ratchet wheel (5) is one-way locking, the binding tape (2) can only be tightened, but cannot be drawn out. By improving the structure, a ratchet wheel control portion is separated from the strapping tape, therefore improving the reliability and the stability when manipulating the anti-loosening strapping tape device.

The utility model patent No. 012392766 discloses a anti-loose strap device, which comprises a strap, one end of the strap is wound on a rotating shaft, and the rotating shaft is fixed on the bracket, and one end of the rotating shaft has a tractor, and the rotating shaft is arranged on the shaft. A ratchet, a clutch and a spring are connected, wherein a fixed connection between the ratchet and the rotating shaft, the clutch is rotatable on the rotating shaft, the spring abuts the clutch against the ratchet, the pawl is provided on the bracket, and the torsion spring is arranged between the pawl and the bracket There are bumps and pawl limit grooves on the clutch. The device spring urges the clutch against the ratchet, that is, the friction between the ratchet and the clutch is used to rotate the clutch by the rotation of the ratchet. Corresponding to the position of the groove on the clutch, the pawl locks the ratchet, and the strap can only be tightened. Unable to pull out the purpose. For structural reasons, such a loose-locking strap device has the drawback of being inconvenient to handle during repeated operations, such as repeated loose and tight operations. At the same time, the above-mentioned strap is wound around the shaft between the two ratchets, and the operating members and the straps for controlling the pawl of the ratchet are housed in the same housing, and the malfunction caused by the winding is liable to occur.

The rotating shaft is serially connected with a ratchet, a clutch cam and a spring, wherein the ratchet and the rotating shaft are fixedly connected, and the clutch cam can be in the rotating shaft. Rotating up, the spring is between the ratchet and the clutch cam, the clutch cam is pressed against the outer bracket under the action of the spring, the clutch cam has an operating handle, the buckle is arranged on the outer bracket, the buckle plate can be rotated, and the outer bracket is further The locking torsion spring has the force of locking the torsion spring to rotate the gusset plate to the position of the one-way locking ratchet, and rotates the clutch cam with the operating handle. In the movable range of the clutch cam, the clutch cam can overcome the locking of the gusset plate Twist The force of the spring realizes the one-way locking of the buckle plate to the ratchet and the tripping of the buckle plate to the ratchet.

本实用新型的防松捆扎带装置，在使用时，可通过转动操作手把，把离合凸轮转动到扣板脱离棘轮的位置，绑带在外力的作用下可随意拉出，松手即可自动收紧，然后把离合凸轮转动到扣板单向锁定棘轮的位置，由于对这种棘轮的锁定是单向锁定，绑带只能收紧不能拉出。同时由于棘轮、扣板和锁紧扭簧在外支架上，实现棘轮控制部分和捆扎带分离。因此，本实用新型是一种操控方便、稳定可靠的防松捆扎带装置。The anti-loose strap device of the utility model can rotate the handlebar and rotate the clutch cam to the position where the buckle plate is disengaged from the ratchet wheel during use, and the strap can be pulled out freely under the action of external force, and the handle can be automatically received. Tightly, then the clutch cam is rotated to the position where the yoke locks the unidirectional lock. Since the locking of the ratchet is unidirectional locking, the strap can only be tightened and cannot be pulled out. At the same time, the ratchet control portion and the strap are separated due to the ratchet, the pinch plate and the locking torsion spring on the outer bracket. Therefore, the utility model is a loose-proof strapping device which is convenient to operate, stable and reliable.
