Description

Technical Field

[0001] The utility model relates to the technical field of vehicle tensioners, and specifically relates to a vehicle tensioner provided with a structure for preventing the breakage and gathering of binding straps. Background Art

[0002] A vehicle tensioner is an auxiliary tool with a fixing function used during the transportation, movement, loading, or storage of goods, and is widely used in fields such as logistics, truck transportation bundling, and goods fixing. According to the different types of binding members, it is divided into webbing tensioners, chain tensioners, wire rope tensioners, etc. Among them, the webbing tensioner is increasingly favored by people due to its advantages such as light weight, wide application range, and convenient operation. Specifically, when using a webbing tensioner, it is usually used in conjunction with two binding straps, one long and one short. The short end is fixed to the short support end of the tensioner, and one end of the long binding strap passes through the positioning hole of the tensioner. Then, the binding strap is adjusted to a suitable position, and the two ends of the binding strap should be respectively hooked to both ends of the goods to fix the goods.

[0003] However, when fixing goods with a webbing tensioner, during the binding process where the binding strap passes through the positioning hole, the positioning block will continuously rub against the binding strap. After long-term use, the positioning block is prone to wear and is inconvenient to replace, which will directly affect the overall use of the tensioner.

[0004] To overcome the above defects, the prior art (a Chinese patent with the publication number CN220923951U and the application date of September 14, 2023) provides a wear-resistant tensioner for vehicle transportation bundling. Through the provided connection component, it is convenient to quickly fix the protective shell and the protective bottom plate on the outside of the positioning plate. The connecting block at the bottom end of the protective shell is extended into the connecting groove, so that the clamping block extends into the connecting groove under the action of the limiting block and the spring to complete the fixation of the protective shell, making it more convenient to use. It is beneficial to protect the positioning plate during long-term use. There is no need to replace the entire device, and only the protective shell and the protective bottom plate need to be replaced, which is more convenient to use and saves costs.

[0005] Although the prior art can achieve wear-resistant fastening between the tensioner and the longer binding strap, during the actual working process of the tensioner, rotational friction will still occur continuously between its short support end and the shorter binding strap during transportation. After long-term use, it will cause the binding strap to wear and even break, which is not conducive to firmly locking the goods, and the short binding strap needs to be replaced frequently, resulting in poor practicability of the device.

[0006] In view of the above problems, it is urgent to innovate and design on the basis of the original equipment. Therefore, we propose a vehicle tensioner provided with a structure for preventing the breakage and gathering of binding straps, which can well solve the above problems. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide an automobile tightener with a restraint belt anti-breakage and retraction structure, so as to solve the problem proposed in the above background technology that during the actual working process of the tightener, rotation friction still occurs continuously between its short support end and the relatively short restraint belt during transportation. After long-term use, the restraint belt will be worn or even broken, which is not conducive to firmly locking the goods, and the short restraint belt needs to be replaced frequently, resulting in poor practicability of the device.

[0008] To achieve the above purpose, the present utility model provides the following technical solution: an automobile tightener with a restraint belt anti-breakage and retraction structure, including two movable plates, a positioning block is movably sleeved between the two movable plates, two ratchets are fixedly connected to the outside of the positioning block, a handle is fixedly connected between one sides of the two movable plates, and two rotating plates are rotatably sleeved on the outside of the positioning block;

[0009] A fixing rod is installed between the two rotating plates, a short restraint belt is sleeved on the outside of the fixing rod, a hook is sleeved on the inner side of the top of the short restraint belt, and by connecting the hook to the tightener device through the short restraint belt, it is convenient to adjust the length of the longer restraint belt on the other side after the hook is hooked on one side of the goods, so as to realize the flexible fastening of the goods;

[0010] Retraction components are arranged on both sides of the short restraint belt. The retraction components include fastening plates and fastening sleeve shells that are symmetrically attached to both sides of the hook. A number of sliding grooves are formed on the two rotating plates, and the two fastening sleeve shells are slidably limited between the two rotating plates through the corresponding sliding grooves. A support frame is fixedly connected between the two sides of the two rotating plates, an installation block is formed at the center of the support frame, a fastening screw is threadedly connected to the inside of the installation block, and one side of the fastening screw is movably inserted into the inside of the fixed shell. By setting the retraction components, the short restraint belt can be firmly sleeved on the outside of the fixing rod by using the two fastening plates and the fastening sleeve shells to wrap the two sides of the short restraint belt and the two fastening screws to abut against the corresponding fastening plates, and rotation friction will not occur, avoiding the situation that the short restraint belt is worn or broken due to long-term rotation friction, thereby ensuring the firm locking of the tightener device and the two restraint belts to the goods, and enhancing the practicability of the device.

[0011] Preferably, the inner side of the positioning block is formed with a mutually fitting wavy convex structure, which can increase the fastening effect of the positioning block on the long restraint belt clamped between them, so as to prevent the long restraint belt from sliding when fixing the goods, resulting in instability during the transportation and placement of the goods.

[0012] Preferably, the two fastening sleeves are semi-circular structures and cover the part of the short restraint belt that is connected to the outside of the fixing rod. The fastening plate is fixedly connected to the top of the fastening sleeve and covers the part of the short restraint belt that is located above the fixing rod and fits therewith.

[0013] Preferably, the support frame is composed of two crossed oblique rods, the mounting block is formed at the intersection and corresponds to the position of the fixed shell. The structure of the support frame can reduce the overall weight of the device while achieving a stable connection between the fastening screws and the fixed shell.

[0014] Preferably, a buffer assembly is provided on the inner side of the fixed shell, and the buffer assembly includes a moving block slidably connected to the inner side of the fixed shell, a spring is fixedly connected between the moving block and the side wall of the fastening plate, and the end of the fastening screw abuts against the moving block. By setting the buffer assembly, the characteristics of the spring can be utilized to achieve elastic locking of the fastening screw to the fastening plate and the fastening sleeve, so that the short restraining belt can swing slightly along the fixing rod to eliminate the vibration and shaking of the goods during transportation, thereby increasing the stability of the device in fixing the goods.

[0015] Preferably, protrusions are formed at both ends of the outer wall of the movable block, and grooves matching the size of the protrusions are formed at both ends of the inner wall of the fixed shell. The protrusions slide on the inner side of the grooves. Through the limited sliding of the protrusions and the grooves, when the fastening screw pushes the movable block to move toward the inner side of the fixed shell, only translation will occur, and no axial rotation will occur, so as to provide anti-twisting protection for the compressed spring.

[0016] Preferably, the two ends of the fixing rod are inserted into the inner sides of the circular holes formed in the two rotating plates, and the parts exposed from the outer sides of the two rotating plates are formed with threaded protrusions, and the outer sides of the threaded protrusions are threadedly connected with mounting nuts, and the fixing rod can be firmly installed between the two rotating plates through the two mounting nuts. When the short restraint strap needs to be replaced, it is only necessary to remove the mounting nut on one side first, and pull the fixing rod out of the circular hole on the other side, and then loosen the two fastening screws so that the fastening plates and the fastening sleeves release the lock on the short restraint strap, and the short restraint strap can be easily pulled out from above the two rotating plates for easy disassembly and replacement.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the automobile tensioner with the anti-breaking and tightening structure of the tie belt can make the short tie belt firmly sleeved on the outside of the fixing rod without rotational friction by setting a tightening assembly, using two fastening plates and a fastening sleeve to cover the two sides of the short tie belt and two fastening screws to abut against the fastening plate, thereby avoiding the wear and tear of the short tie belt, and then ensuring the firm locking of the goods by the tensioner device and the two tie belts.
