Description

A car carrier strapping device Technical Field

[0001] This utility model belongs to the field of binding devices, and specifically relates to a car carrier binding device. Background Technology

[0002] During land or sea transport, vehicles need to be secured. Car carrier strapping devices are a type of device used to secure vehicle tires, thereby preventing the vehicle from moving freely during transport.

[0003] The authorized publication number "CN207106321U" describes "a car carrier tie-down device, belonging to the field of logistics equipment technology. This car carrier tie-down device includes a housing, a belt shaft, and a tie-down strap. The two ends of the belt shaft are rotatably mounted on the housing. A hook is connected to the housing. One end of the tie-down strap is connected to a hook, and the other end of the tie-down strap is connected to the belt shaft and the tie-down strap is wound around the belt shaft. On one side of the tie-down strap, multiple marking lines are arranged at intervals along the length of the tie-down strap, with a distance of 15cm-25cm between adjacent marking lines. The tire size is also marked on the tie-down strap at each marking line."

[0004] The aforementioned patent addresses the problem that existing car carrier strapping devices cannot predict the required length of strapping for different tire sizes. However, the aforementioned patent is not easy to implement. Although the length can be adjusted according to the tire size, tires will wear out, causing the tire size to become smaller, and the tire cannot be secured according to the markings. Summary of the Invention

[0005] The purpose of this invention is to provide a car carrier securing device that solves the problem in the prior art where tires wear down, causing them to shrink and making it impossible to secure them according to the markings.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A car carrier securing device includes:

[0008] Car support plate;

[0009] There are two upright plates, which are symmetrically arranged at the bottom of the car support plate;

[0010] The winding mechanism is mounted on two upright plates;

[0011] The binding mechanism is located on the car support plate and the winding mechanism;

[0012] The driving mechanism is located on the upright board.

[0013] As a preferred embodiment of this utility model, the winding mechanism includes:

[0014] The winding component is located on two upright plates;

[0015] A ratchet mechanism is provided on the upright plate, and the ratchet mechanism is connected to the winding component.

[0016] In a preferred embodiment of this utility model, the winding component includes a handwheel, a rotating shaft, a locking screw, a winding roller, and gears. The winding roller is rotatably connected between two upright plates, and both ends of the winding roller rotatably pass through the two upright plates and extend to the outer sides of the two upright plates. The rotating shaft is rotatably connected between the two upright plates, and both ends of the rotating shaft rotatably pass through the two upright plates and extend to the outer sides of the two upright plates. The handwheel is fixedly connected to the rotating shaft. There are two gears, one of which is fixedly connected to the rotating shaft, and the other gear is fixedly connected to the winding roller. The two gears mesh with each other. The locking screw is threadedly connected to the handwheel, and one end of the locking screw is movably inserted into the upright plate.

[0017] In a preferred embodiment of this utility model, the ratchet mechanism includes a ratchet, a spring, and a pawl. The ratchet is fixedly connected to the take-up roller, the pawl is rotatably connected to the upright plate, and the pawl and the ratchet mesh with each other. The spring is fixedly connected between the car support plate and the pawl.

[0018] As a preferred embodiment of this utility model, the binding mechanism includes a through hole, a hook, and a strap. Multiple through holes are provided, all of which are opened on the car support plate and are evenly distributed. The hook is engaged with one of the through holes. One end of the strap is fixedly connected to the hook, and the other end of the strap is fixedly connected to the take-up roller.

[0019] In a preferred embodiment of this utility model, the pushing mechanism includes a push plate and an electric telescopic rod. One end of the electric telescopic rod is fixedly connected to the upright plate, and the push plate is fixedly connected to the extended end of the electric telescopic rod, with the push plate aligned with the pawl.

[0020] In a preferred embodiment of this utility model, a transmission roller is rotatably connected to the car support plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. In this design, the handwheel facilitates the rotation of the shaft. The rotation of the shaft drives the gears to rotate. Since the two gears mesh with each other, they rotate simultaneously. The rotation of the gears drives the take-up roller to rotate, which in turn winds up the strapping, allowing the strapping to be tied more tightly.

[0023] 2. In this solution, the spring force can hold the pawl in place, causing the pawl to engage with the ratchet. The engagement of the pawl and the ratchet allows the ratchet to rotate only in one direction. Since the ratchet is fixedly connected to the take-up roller, the take-up roller can tighten the strap as it winds up. When the strap is taut from being wound up, the engagement of the pawl and the ratchet restricts the rotation of the take-up roller.

[0024] 3. In this solution, the through hole is used to hook the hook, and the hook is used to fix one end of the strap. The strap can be put on the wheel of the car to tie the tire.

[0025] 4. In this solution, the retraction of the electric telescopic rod drives the push plate to move, the movement of the push plate pushes the pawl to rotate, and the rotation of the pawl compresses the spring, causing the spring to generate compressive elastic force. After the pawl rotates, it engages and separates from the ratchet, allowing the taut strap to be loosened. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figures 1-4. The technical solution provided in this embodiment is as follows:

[0034] A car carrier binding device comprises a car support plate 1, upright plates 9, a winding mechanism, a binding mechanism, and a pushing mechanism. Two upright plates 9 are provided, symmetrically arranged at the bottom of the car support plate 1.

[0035] In a specific embodiment of this utility model, the two vertical plates 9 are provided to connect the rotating shaft 7 and the winding roller 10.

[0036] Specifically, the winding component is mounted on two upright plates 9. The winding component includes a handwheel 6, a rotating shaft 7, a locking screw 8, a winding roller 10, and a gear 11. The winding roller 10 is rotatably connected between the two upright plates 9, and both ends of the winding roller 10 rotatably pass through the two upright plates 9 and extend to the outside of the two upright plates 9. The rotating shaft 7 is rotatably connected between the two upright plates 9, and both ends of the rotating shaft 7 rotatably pass through the two upright plates 9 and extend to the outside of the two upright plates 9. The handwheel 6 is fixedly connected to the rotating shaft 7. There are two gears 11, one of which is fixedly connected to the rotating shaft 7, and the other gear is fixedly connected to the winding roller 10. The two gears 11 mesh with each other. The locking screw 8 is threadedly connected to the handwheel 6, and one end of the locking screw 8 is movably inserted into the upright plate 9.

[0037] In a specific embodiment of this utility model, the handwheel 6 is designed to facilitate the rotation of the shaft 7. The rotation of the shaft 7 drives the gear 11 to rotate. Since the two gears 11 mesh with each other, the two gears 11 rotate simultaneously. The rotation of the gears 11 drives the winding roller 10 to rotate. The rotation of the winding roller 10 thereby winds up the strap 4, so that the strap 4 can be tied more tightly.

[0038] Specifically, the ratchet mechanism is located on the upright plate 9 and is connected to the winding component. The ratchet mechanism includes a ratchet 12, a spring 13, and a pawl 14. The ratchet 12 is fixedly connected to the winding roller 10, and the pawl 14 is rotatably connected to the upright plate 9. The pawl 14 and the ratchet 12 mesh with each other. The spring 13 is fixedly connected between the car support plate 1 and the pawl 14.

[0039] In a specific embodiment of this utility model, the spring force of the spring 13 can hold the pawl 14, so that the pawl 14 engages with the ratchet 12. The engagement of the pawl 14 with the ratchet 12 makes the ratchet 12 rotate only in one direction. Since the ratchet 12 is fixedly connected to the take-up roller 10, the take-up roller 10 can make the strap 4 tighter and tighter when it is winding. When the strap 4 is taut from being wound up, the engagement of the pawl 14 with the ratchet 12 can restrict the rotation of the take-up roller 10.

[0040] Specifically, the binding mechanism is located on the car support plate 1 and the winding mechanism. The binding mechanism includes a through hole 2, a hook 3 and a strap 4. There are multiple through holes 2, which are all opened on the car support plate 1 and are evenly distributed. The hook 3 is engaged with one of the through holes 2. One end of the strap 4 is fixedly connected to the hook 3 and the other end of the strap 4 is fixedly connected to the winding roller 10.

[0041] In a specific embodiment of this utility model, the through hole 2 is used to hook the hook 3, and the hook 3 is used to fix one end of the strap 4. The strap 4 can be put on the wheel of the car to tie the tire.

[0042] Specifically, the pushing mechanism is located on the upright plate 9. The pushing mechanism includes a push plate 15 and an electric telescopic rod 16. One end of the electric telescopic rod 16 is fixedly connected to the upright plate 9, and the push plate 15 is fixedly connected to the extended end of the electric telescopic rod 16. The push plate 15 is aligned with the pawl 14.

[0043] In a specific embodiment of this utility model, the electric telescopic rod 16 retracts to drive the push plate 15 to move, the push plate 15 moves to push the pawl 14 to rotate, the pawl 14 rotates and compresses the spring 13, so that the spring 13 generates a compressive force, the pawl 14 rotates and engages with the ratchet 12 to separate, so that the taut strap 4 can be loosened.

[0044] Specifically, a transmission roller 5 is rotatably connected to the car support plate 1.

[0045] In a specific embodiment of this utility model, the transmission roller 5 can reduce the friction between the strap 4 and the car support plate 1 when the strap is wound up, thereby increasing the service life.

[0046] The working principle or process of the car carrier binding device provided by this utility model is as follows: hook 3 is hooked onto through hole 2, handwheel 6 is rotated, handwheel 6 rotates and drives shaft 7 to rotate, shaft 7 rotates and drives gear 11 to rotate. Since the two gears 11 mesh with each other, the two gears 11 rotate simultaneously. The rotation of gear 11 drives take-up roller 10 to rotate, take-up roller 10 rotates and takes up binding strap 4. Take-up roller 10 rotates and drives ratchet 12 to rotate, ratchet 12 rotates and pushes pawl 14 to rotate. After pawl 14 rotates, it compresses spring 13, so that spring 13 generates compression force. The force of spring 13 pushes pawl 14 to re-engage with ratchet 12. Locking screw 8 is threaded onto handwheel 6 and movably inserted into vertical plate 9, which can restrict the rotation of handwheel 6. Electric telescopic rod 16 retracts and drives push plate 15 to move. Push plate 15 moves and pushes pawl 14 to rotate, so that pawl 14 engages and disengages from ratchet 12, so that the taut binding strap 4 is loosened.

[0047] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
