Description

Technical Field

[0001] This utility model relates to a spring fixing mechanism for a car seat. Background Technology

[0002] In the current technology, car seat springs are generally installed in a fixed manner, that is, the two ends of the spring are fixedly connected to the car seat frame. When the spring becomes loose or other problems require maintenance, it cannot be replaced individually, but the whole set must be replaced, which not only incurs maintenance costs, but also wastes materials. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spring fixing mechanism for automobile seats.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a spring fixing mechanism for a car seat, including a main fixing mechanism and a secondary fixing mechanism. The main fixing mechanism includes a main fixing rod, a main pull rod and two fastening units. The main fixing rod and the main pull rod are arranged in parallel. The fastening unit includes a screw and a nut. One end of the screw passes through the main fixing rod and is fixedly connected to the main pull rod. The other end of the screw is connected to the nut.

[0005] The secondary fixing mechanism includes a secondary fixing rod and a secondary pull rod, which are arranged in parallel. The secondary pull rod is mounted on the secondary fixing rod. The main pull rod and the secondary pull rod are located between the main fixing rod and the secondary fixing rod. The main pull rod and the secondary pull rod have an equal number of hooks on their opposite sides. The hooks on the main pull rod and the secondary pull rod are opposite each other and correspond one-to-one.

[0006] An anti-slip washer is provided between the nut and the main fixing rod, and the anti-slip washer is sleeved on the screw rod;

[0007] A rubber strip is provided between the main fixing rod and the main tie rod.

[0008] Preferably, the anti-slip pad is fixed to the main fixing rod.

[0009] Preferably, the main fixing rod is provided with a groove that matches the rubber strip, and the rubber strip is embedded in the groove.

[0010] The beneficial effects of this utility model are that the spring fixing mechanism of the car seat adopts a detachable structure design. The two ends of the spring are tightened by the main fixing mechanism and the auxiliary fixing mechanism respectively, and then the final fastening is achieved by the cooperation of the nut and the screw. This facilitates the disassembly and maintenance of the spring, reduces maintenance costs, and improves the ease of spring installation. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-3 As shown, a spring fixing mechanism for a car seat includes a main fixing mechanism and a secondary fixing mechanism. The main fixing mechanism includes a main fixing rod 2, a main tie rod 3, and two fastening units. The main fixing rod 2 and the main tie rod 3 are arranged in parallel. The fastening unit includes a screw 6 and a nut 7. One end of the screw 6 passes through the main fixing rod 2 and is fixedly connected to the main tie rod 3, and the other end of the screw 6 is connected to the nut 7.

[0018] The secondary fixing mechanism includes a secondary fixing rod 4 and a secondary pull rod 5, which are arranged in parallel. The secondary pull rod 5 is mounted on the secondary fixing rod 4. The main pull rod 3 and the secondary pull rod 5 are located between the main fixing rod 2 and the secondary fixing rod 4. The main pull rod 3 and the secondary pull rod 5 have an equal number of hooks 9 on their opposite sides. The hooks 9 on the main pull rod 3 and the secondary pull rod 5 are arranged opposite each other and correspond one-to-one.

[0019] An anti-slip washer 8 is provided between the nut 7 and the main fixing rod 2, and the anti-slip washer 8 is sleeved on the screw rod 6;

[0020] A rubber strip 10 is provided between the main fixing rod 2 and the main tie rod 3.

[0021] Preferably, the anti-slip pad 8 is fixed on the main fixing rod 2.

[0022] Preferably, the main fixing rod 2 is provided with a groove that matches the rubber strip 10, and the rubber strip 10 is embedded in the groove.

[0023] During installation, tighten nut 7 so that screw 6 passes through one end of main fixing rod 2 and moves towards auxiliary fixing rod 4, allowing spring 1 to hang unobstructed on the corresponding two hooks 9 on main tie rod 3 and auxiliary tie rod 5, thus achieving unobstructed installation of spring 1. Then, tighten nut 7 in the opposite direction, and nut 7 drives screw 6 to move in the opposite direction to auxiliary fixing rod 4, thereby tightening spring 1 until auxiliary tie rod 3 presses against rubber strip 10. At this point, spring 1 is in the completed installation state.

[0024] A washer 8 with anti-slip function is set between the nut 7 and the main fixing rod 2, mainly to facilitate the reverse rotation of the nut 7 and ensure the stability of the nut 7 in the tightened state.

[0025] A rubber strip 10 is installed between the main fixing rod 2 and the main tie rod 3 to create a gap between them. This is mainly to reduce the rigid compression between the main fixing rod 2 and the main tie rod 3, ensuring the stability of the structure. It also reduces the rigid stress on the screw 6 caused by the main tie rod 3, thus reducing damage to the screw 6. That is, when the main tie rod 3 is about to fit with the main fixing rod 2, if the bolt 7 is tightened on one side, the rubber strip 10 can help support the screw 10 on the other side. A groove is provided on the main fixing rod 2 to facilitate the installation and fixing of the rubber strip 10, preventing it from falling between the main fixing rod 2 and the main tie rod 3 when installing the spring 1, thus reducing the complexity of the installation steps.

[0026] Compared with existing technologies, the spring fixing mechanism of this car seat adopts a detachable structure design. The main fixing mechanism and the auxiliary fixing mechanism tighten both ends of the spring 1 respectively, and then the final fastening is achieved through the cooperation of the nut 7 and the screw 6. This facilitates the disassembly and maintenance of the spring 1, reduces maintenance costs, and improves the ease of installation of the spring 1.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
