Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a universal pulley for 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] Traditional skateboard wheel designs often clearly distinguish the functions of the front and rear wheels. For example, the front wheel usually focuses more on steering flexibility and stability, while the rear wheel focuses more on thrust and speed. However, this design limits the flexibility and adaptability of skateboards in different road conditions and usage scenarios to a certain extent. Utility Model Content

[0004] The utility model aims to provide a universal pulley for a skateboard, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a pulley for a skateboard that is universal for front and rear, comprising a main body mechanism, a pulley mechanism is arranged at the bottom of the main body mechanism;

[0006] The main body mechanism comprises a slide plate, the bottom of the slide plate is fixedly connected to a base by screws, the inner wall of the base is provided with a self-locking mechanism, the top of the base is slidably connected to a locking block, the top of the locking block is fixedly connected to a spring piece by bolts, the bottom of the locking block is fixedly connected to a guide block, and a slider is slidably connected between the base and the guide block;

[0007] The pulley mechanism includes a base, a center column screw is fixedly connected to the bottom of the base, a shock absorbing mechanism is arranged on the surface of the center column screw, the center column screw is threadedly connected to a pulley bracket through a locking nut, and PU wheels are arranged on both sides of the pulley bracket.

[0008] Furthermore, the pulley mechanism is connected to the base through a center column screw, and the PU wheels on both sides are in direct contact with the ground, providing the friction required for the skateboard to slide. When the front and rear pulley positions of the skateboard need to be fixed, the locking block is moved downward by manually operating the pressing piece of the locking block, and the inclined surface on the locking block cooperates with the protective lock to push the protective lock into the base to lock the pulley. When released, the spring resets the protective lock and cooperates with the groove on the locking block to lock it again. The self-locking mechanism can quickly and conveniently lock and unlock the pulley to ensure that the skateboard can stay stably in place when it does not need to slide. The design of the pulley mechanism makes the skateboard universal for front and rear, and can provide the same sliding effect and stability whether it is installed at the front or rear end of the skateboard.

[0009] Preferably, the locking block includes a connecting plate, a clamping block driving the inclined surface is fixedly connected to the middle of the lower end of the connecting plate, pressing plates are fixedly connected to both ends of the connecting plate, and a groove is provided at the upper end of the clamping block of the locking block on the other side of the inclined surface.

[0010] Furthermore, the locking block has a specific structure, including a connecting plate, a card block and a pressing plate. The card block is provided with an inclined surface and a groove. These designs are to cooperate with the self-locking mechanism to achieve the locking and unlocking of the pulley.

[0012] Furthermore, a spring is fixedly connected to the front end of the protection lock, which is used to reset the protection lock to the initial position when the lock block is released. When the lock block moves downward, the inclined surface on its card block will cooperate with the protection lock to push the protection lock into the base to unlock the pulley. When the lock block is released, the spring will reset the protection lock to cooperate with the groove on the card block of the lock block to lock the pulley.

[0013] Preferably, the shock absorbing mechanism comprises a lower bowl pad, a large shock absorber is arranged at the bottom of the lower bowl pad, a medium shock absorber is arranged at the bottom of the large shock absorber, and an upper bowl pad is arranged at the bottom of the medium shock absorber.

[0014] Furthermore, the practical shock-absorbing mechanism is composed of a lower bowl pad, a large shock-absorbing, a medium shock-absorbing and an upper bowl pad. These components are sequentially mounted on the center column screw to form a multi-layer shock-absorbing structure. During sliding, vibrations caused by uneven road surface or other reasons will be transmitted to the skateboard through the pulley mechanism. At this time, the lower bowl pad, large shock-absorbing, upper bowl pad and medium shock-absorbing in the shock-absorbing mechanism will buffer and disperse these vibrations in turn, thereby reducing the vibration transmitted to the skater's feet, improving the comfort and stability of sliding, and reducing the skater's fatigue.

[0015] 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.

[0020] First, the pulley mechanism of the utility model is connected to the base through the center column screw, and the PU wheels on both sides are in direct contact with the ground, providing the friction force required for the skateboard to slide. When the front and rear pulley positions of the skateboard need to be fixed, the locking block is moved downward by manually operating the pressing piece of the locking block, and the inclined surface on the card block cooperates with the protective lock to push the protective lock into the base to lock the pulley. When released, the spring resets the protective lock and cooperates with the groove on the card block of the locking block to lock it again.
