Description

Technical Field

[0001] The utility model relates to the technical field of skateboards, in particular to a pulley disassembly and assembly component of a skateboard. Background Art

[0002] Skateboard is a very popular game tool. This kind of game tool with a sense of speed and stunts has always been loved by teenagers. Generally, the existing skateboard is mainly a set of rollers on the bottom surface of the front and rear ends of a board body. The user steps on the board body of the skateboard with one foot and uses the other foot to paddle on the ground. The friction with the ground makes the skateboard slide forward to generate speed. In addition to moving forward, it can also be used to perform various stunts to generate more fun. Common skateboards include: ordinary skateboards, snake boards and fingerboards, etc. Ordinary skateboards include: single-climbing skateboards, double-climbing skateboards, longboards, etc. Snake boards are also called dragon boards or swimming dragon boards. Different types of skateboards have different usage methods and different functions.

[0003] Currently, the skateboards on the market have single functions and are not easy to disassemble and replace with different pulleys to meet the needs of users with different proficiency levels. Utility Model Content

[0006] The main structure comprises a slide plate, the bottom of which is fixedly connected to a base via screws, a locking block is arranged inside the base, a spring is fixedly connected to the bottom of the locking block, and a guide plate is fixedly connected to the bottom of the base.

[0007] Preferably, the pulley structure includes a base, a sliding block is arranged on the top of the base, a center column screw is fixedly installed on the bottom of the base, the center column screw is threadedly connected to the pulley bracket through a locking nut, and PU wheels are arranged on both sides of the pulley bracket.

[0008] Preferably, an installation groove is opened on the inner wall of the base, a protection lock is arranged in the installation groove, a return spring is arranged at the bottom of the protection lock, and one end of the return spring away from the protection lock is fixedly connected to the inner wall of the base.

[0009] Preferably, the outer surface of the center column screw is provided with a lower bowl pad, a large shock absorber, a medium shock absorber and an upper bowl pad from top to bottom.

[0010] Preferably, the center column screw passes through the lower bowl pad, the large shock-absorbing pad, the medium shock-absorbing pad upper bowl pad and the pulley bracket and is threadedly connected with a lock nut.

[0011] Preferably, the facing sides of the upper bowl pad and the lower bowl pad are both notched, and the upper bowl pad and the lower bowl pad cover the large shock-absorbing pad and the medium shock-absorbing pad through the notches.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] When the locking block is moved downward, the reset spring exerts an outward force on the protection lock, so that the protection lock limits and fixes the locking block, and the pulley bracket and the PU wheel are stably installed under the skateboard. When it is necessary to replace and install different pulley assemblies, it is only necessary to press the protection lock to release the limit fixation of the locking block, pull the base to make the locking block retract into the base by the extrusion force, release the limit fixation of the base, and separate the base from the base to replace different pulley assemblies. The disassembly and assembly assembly has the advantages of simple structure, convenient disassembly and stable installation. Different pulley assemblies can be easily disassembled and replaced, so that the function of the skateboard is no longer single, and the needs of users with different proficiency can be met.

[0014] Second, the utility model provides the pulley assembly with good shock-absorbing and buffering functions by arranging the lower bowl pad, the large shock-absorbing, the medium shock-absorbing and the upper bowl pad, thereby reducing the impact on the pulley assembly when using the skateboard and increasing the service life of the pulley assembly.
