Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing, specifically an anti-disengagement component for trolley traction. Background Technology

[0002] Currently, when moving heavy-duty trolleys within the workshop, an electric tractor is required for towing. The tractor and the trolley are connected by a hook and a hanging ring. The hook is a horizontal plate welded to the rear of the tractor, with a limit post welded to the plate. The hanging ring is rotatably connected to the front of the trolley. During use, the hanging ring is put onto the limit post for connection. However, it has been found that this connection method has low reliability and may detach when turning or encountering uneven road surfaces, posing a certain safety hazard. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-disengagement component for trolley traction. This component effectively prevents the trolley from disengaging during traction, improves connection stability, avoids safety hazards, and is more convenient and flexible to use due to its contact connection method.

[0004] The technical solution of this utility model is: an anti-disengagement component for trolley traction, including a fastener and a hanging ring that cooperates with the fastener. The fastener includes a first mounting plate, and a first horizontal plate and a second horizontal plate arranged in parallel are provided on one side of the first mounting plate. A space for the hanging ring to pass through is formed between the first horizontal plate and the second horizontal plate. The first horizontal plate has a first through groove, and the second horizontal plate has a second through groove corresponding to the position of the first through groove. The front end of the first through groove is provided with a bushing, and a hinge shaft is rotatably connected inside the bushing, and a limiting rod corresponding to the position of the first through groove is connected through the hinge shaft. The limiting rod can rotate vertically under its own weight, and the front end of the second limiting groove can limit the bottom of the limiting rod.

[0005] Preferably, the top of the limiting rod is provided with a foot pedal, and the foot pedal and the limiting rod are arranged in an L-shape.

[0006] Preferably, a set of reinforcing vertical plates are connected between the first horizontal plate and the second horizontal plate.

[0007] Preferably, the hanging ring includes a second mounting plate and a U-shaped ring fixedly connected to the second mounting plate.

[0008] Preferably, both the first mounting plate and the second mounting plate are provided with a set of bolt assembly holes.

[0009] Compared with the prior art, this utility model has the following advantages: The outer edge of the hanging ring can push the limiting rod to rotate around the hinge axis. As the front end of the hanging ring continues to move to the other side of the bottom of the limiting rod, it loses support for the bottom of the limiting rod. The bottom of the limiting rod rotates and falls, and it gets stuck in the limiting ring, thus realizing the connection between the hanging ring and the fastener. This connection is safer and more stable, and it can effectively prevent disengagement when turning or driving on uneven roads. In addition, when it is necessary to unlock both, simply step on the top of the limit bar with your foot to rotate the bottom of the limit bar upwards, which will move the hanging ring position to unlock it, avoiding the need to bend over to unlock it, making it more flexible and convenient to use.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0012] like Figures 1 to 3 An anti-disengagement assembly for trolley traction includes a fastener and a hanging ring. The hanging ring includes a second mounting plate 12 and a U-shaped ring 11. The two ends of the U-shaped ring 11 are welded and fixedly connected to the second mounting plate 12. Both the second mounting plate 12 and the U-shaped ring 11 are made of stainless steel.

[0013] The fastener includes a first mounting plate 1, on one side of which a first horizontal plate 2 and a second horizontal plate 4 are welded together in parallel. A space is formed between the first horizontal plate 2 and the second horizontal plate 4 for the hanging ring to pass through. The first mounting plate 1, the first horizontal plate 2 and the second horizontal plate 4 are all made of stainless steel.

[0014] The first horizontal plate 2 has a first through groove 5, and the second horizontal plate 4 has a second through groove 6 that corresponds vertically to the position of the first through groove 5.

[0015] A pair of steel pipe bushings 10 are welded to the upper end face of the first horizontal plate 2 at the front end position of the first through groove 5. A hinge shaft 9 is rotatably connected inside the pair of bushings 10. The middle part of the hinge shaft 9 is exposed outside the bushing 10, and a hinge shaft 9 limiting rod 7 is welded on it. The position of the limiting rod 7 corresponds exactly to the position of the first through groove 5 and the second through groove 6.

[0016] The limiting rod 7 can rotate vertically under its own weight, and the front end of the second limiting groove limits the bottom of the limiting rod 7.

[0017] Working principle: such as Figure 1 As shown, the fastener is connected to the tractor, and the hook is connected to the trolley. When connecting the two, the trolley is moved so that the hook is inserted into the space between the first horizontal plate 2 and the second horizontal plate 4. The outer edge of the hook pushes the limiting rod 7 to rotate around the hinge shaft 9. At this time, the state is as follows. Figure 2 As shown; As the hanging ring continues to move, when its front end reaches the other side of the bottom of the limiting rod 7, it loses support for the bottom of the limiting rod 7. The bottom of the limiting rod 7 then rotates and falls, fitting perfectly into the limiting ring, thus connecting the hanging ring and the fastener. At this point... Figure 3 As shown, this connection is safer and more stable, and can effectively prevent the hook from coming off when turning or driving on uneven surfaces. When unlocking is required, simply step on the top of the limiting rod 7 to rotate it. When the bottom of the limiting rod 7 rotates upward and disengages from the limiting position on the hanging ring, the hanging ring can be moved to unlock it, avoiding the need to bend over to unlock, making it more flexible and convenient to use. Example 2

[0018] This embodiment is a further optimization based on the above embodiment, specifically: like Figures 1 to 3 To facilitate unlocking by foot, a foot pedal 8 is provided at the top of the limit rod 7, and the foot pedal 8 and the limit rod 7 are arranged in an L-shape.

[0019] This allows the limit rod 7 to be flipped by stepping on the foot pedal 8, thereby unlocking the hook. The design is more reasonable and further improves the flexibility of use. Example 3

[0020] This embodiment is a further optimization based on the above embodiment, specifically: like Figures 1 to 3 In this embodiment, a set of reinforcing vertical plates 3 are connected between the first horizontal plate 2 and the second horizontal plate 4. The overall structural strength of this utility model is improved by adding a set of reinforcing vertical plates 3.

[0021] Both the first mounting plate 1 and the second mounting plate 12 are provided with a set of bolt assembly holes. By adding bolt assembly holes, bolts can be used to detachably connect them to the trolley or tractor, which is more convenient than the previous method of welding.

[0022] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
