The clamp steel belt is provided with inclined teeth on the outer side, and the clamp steel belt is fixedly connected through the locking head on both sides. The clamp steel belt is sleeved with a sliding buckle on the outer side, the sliding buckle is welded with a compensation assembly on the inner side, the compensation assembly is welded with an elastic sheet on the inner side, the locking head is welded with a compensation ring on the lower side, the compensation ring is provided with a groove on one side, and the other side is larger than the other side, and the other side is welded with a sliding block edge.

[0004] Although the B-type worm drive reinforced compensation type hoop sets a compensation ring on the lower side of the locking head and drives the inner compensation ring to lock through the clamp steel belt, the compensation ring of the B-type worm drive reinforced compensation type hoop is in surface contact with the clamp steel belt. When the free end of the clamp steel belt passes through the locking head, the friction between the fixed end and the free end of the clamp steel belt will increase, making it more laborious to tighten the clamp steel belt.

[0005] Therefore, we propose an automobile compensation type worm drive hoop. Utility model content

[0007] To achieve the above purpose, the utility model realizes the following technical scheme: an automobile compensation type worm drive hoop, comprising a locking head, wherein the locking head is provided with a clamp steel belt;

[0008] One end of the hoop steel band is fixedly connected with a fixed sheet, accommodating grooves are formed in the front and back sides of the inner wall of the hoop steel band, a compensation strip is fixedly sleeved in the accommodating grooves, two displacement grooves of the same specification and corresponding to the accommodating grooves are formed in the top surface of the fixed sheet, and the width of the compensation strip is one third of the width of the accommodating groove.

[0009] Preferably, the compensation strip is made of styrene butadiene rubber, wherein the styrene butadiene rubber has excellent wear resistance, aging resistance, high strength and elasticity, and is easy to process.

[0010] Preferably, the locking head comprises a locking seat and a worm, the inside of the locking seat and the bottom surface thereof are arc-shaped, the two ends of the worm are rotatably installed on the side walls of the locking seat, and the fixed sheet is fixedly installed on the bottom surface in the inside of the locking seat, wherein one surface of the locking head is in contact with the outer surface of the hose, so as to increase the contact area between the locking head and the hose.

[0011] Preferably, the middle part of the arc surface of the hoop steel band is provided with tooth grooves which are linearly arranged and engaged with the worm, wherein the free end of the hoop steel band is passed through the locking head, and the rotation of the worm can drive the hoop steel band to move in the locking head, so as to make the hoop steel band tightly clamp the surface of the hose.

[0012] The utility model provides a car compensation type worm drive type hoop, has the following beneficial effects:

[0013] The car compensation type worm drive type hoop can compensate the micro deformation and displacement through the deformation of the compensation strip, thereby ensuring the stability and reliability of the hose connection, and when the hoop steel band is tightly clamped on the hose, the compensation strip is clamped in the displacement groove and moves, which is beneficial to reducing the friction between the free end of the hoop steel band and the fixed sheet, and the utility model is more labor-saving to use, and solves the problem that the compensation ring of the prior device increases the friction between the fixed end and the free end of the hoop steel band, thereby making the tightening of the hoop steel band more laborious.

The front and rear sides of the inner wall of the clamping steel band 2 are provided with receiving grooves 24. The receiving grooves 24 are fixedly fitted with compensation strips 3 inside. The top surface of the fixing plate 21 is provided with two relief grooves 22 that correspond to the position of the receiving grooves 24 and are of the same specifications. The width of the compensation strip 3 is one-third of the width of the receiving groove 24. The material of the compensation strip 3 is styrene-butadiene rubber. The deformation of the compensation strip 3 can compensate for the small deformation and displacement, thereby ensuring the stability and reliability of the hose connection. When the clamping steel band 2 is tightened on the hose, the compensation strip 3 will be engaged inside the relief grooves 22 and move along its inner wall, which helps to reduce the friction between the free end of the clamping steel band 2 and the fixing plate 21, making it easier to use.
