Description

Technical Field

[0001] This utility model relates to the technical field of anti-skid chain locking devices, and specifically discloses an anti-skid chain locking device with a simple structure. Background Technology

[0002] The existing anti-skid chains mainly use a chain tension locking method. This method can loosen during operation, causing the chain to fall off and requiring manual adjustment. Installation is difficult and inconvenient for frequent users. Furthermore, the loosening of the chain lock during operation is often not noticed by the driver, leading to the anti-skid chain falling off and injuring the vehicle. Therefore, anti-skid chain locking devices have emerged on the market. The applicant's Chinese utility model patent application (patent number: 202420474693.7) filed on March 12, 2024, discloses a locking device for anti-skid chains, including a housing, a spiral spring, a rotating ratchet, and a locking bar. The spiral spring is fixed inside the housing, the rotating ratchet is connected to the spiral spring, and the rotating ratchet has a coiled steel wire rope. The locking bar is rotatably connected to the inside of the housing, and the locking bar is located on one side of the rotating ratchet. The opening button and locking button are located on the housing. The opening button is in contact with the locking bar. By pressing the opening button, the locking bar is squeezed and disengaged from the rotating ratchet, causing the internal steel wire rope to be pulled out. It is connected to the anti-skid chain side chain through the connector, and then the steel wire rope is pulled back by the internal coil spring through the locking button. The locking device effectively replaces the original chain locking method. It is easy to install and will automatically lock when the anti-skid chain is in motion, preventing the chain from falling off. It effectively increases the performance of the anti-skid chain and the safety performance of the vehicle.

[0003] The aforementioned patents require the use of multiple components (e.g., spiral springs, rotating ratchet, and locking strips), which makes assembly troublesome and increases manufacturing costs. Utility Model Content

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Refer to the instruction manual appendix Figure 1-2 As shown, a simple anti-skid chain locker includes a housing 1, several pulleys rotatably connected to the housing 1, an elastic rope 2, and a hook 10. One end of the elastic rope 2 is fixed to the housing 1, and the other end of the elastic rope 2 is wrapped around the pulleys and extends to the outside of the housing 1. The hook 10 is connected to one end of the elastic rope 2 located on the outside of the housing 1. In use, pulling the hook 10 can cause the elastic rope 2 to extend and retract, connecting the hook 10 to the anti-skid chain. The elastic rope 2 causes the hook 10 to retract towards one side of the housing 1, thereby locking the anti-skid chain. It is easy to install and automatically locks during driving, preventing the chain from falling off. It effectively increases the performance of the anti-skid chain and the safety performance of the vehicle. In addition, this utility model has a compact structure, few parts, convenient assembly, and low manufacturing cost.

[0025] Specifically, the elastic cord sliding groove 14 extends to one end of the outer side of the housing 1 and has a sliding groove opening 15. A hook body connecting block 9 is provided between the hook body 10 and the elastic cord 2. The cross-section of the hook body connecting block 9 is larger than the sliding groove opening 15 to prevent the hook body 10 from moving into the sliding groove opening 15 due to the contraction of the elastic cord 2.

[0026] Specifically, the opening 15 of the sliding groove is larger than the cross-section of the elastic rope sliding groove 14.

[0027] In another preferred embodiment of this invention, the housing 1 is provided with a first rotating shaft 6 and a second rotating shaft 8, and a first pulley 5 and a second pulley 7 are respectively connected to the first rotating shaft 6 and the second rotating shaft 8, and the elastic rope 2 is wound around the first pulley 5 and the second pulley 7.

[0028] In addition, one end of the elastic rope 2 is provided with a locking block 3, and the inside of the housing 1 is provided with a locking groove 4 that cooperates with the locking block 3. One end of the elastic rope 2 is fixedly connected to the locking groove 4 through the locking block 3. The structure is simple and the elastic rope is easy to install.

[0029] Specifically, the housing 1 is rotatably connected to the connecting plate 11 via the connecting plate fixing shaft 13. The connecting plate 11 is provided with a plurality of connecting holes 12. One end of the anti-skid chain can be connected to the connecting plate 11 through the connecting holes 12 on the connecting plate 11, making the anti-skid chain easy to install.

[0031] This technical solution provides a simple anti-skid chain locker, including a housing, several pulleys rotatably connected to the housing, an elastic rope, and a hook. One end of the elastic rope is fixed to the housing, and the other end is wrapped around the pulleys and extends to the outside of the housing. The hook is connected to one end of the elastic rope located on the outside of the housing. In use, pulling the hook can cause the elastic rope to extend and retract, connecting the hook to the anti-skid chain. The elastic rope causes the hook to retract to one side of the housing, thereby locking the anti-skid chain. Installation is simple, and the chain automatically locks during driving, preventing it from falling off. This effectively increases the performance of the anti-skid chain and the safety of the vehicle.
