Description

Sliding plate anti-biting wheel device and sliding plate

Technical Field

The invention relates to a sliding plate anti-biting wheel device and a sliding plate, and belongs to the technical field of sports goods.

Background

Nowadays, more and more people select the slide as a novel fitness mode and a short-distance travel tool, and the characteristics of portability and environmental protection are more and more accepted by people. However, one problem often occurs while people are skating. In the sliding process, when a large-angle turning occurs, the board surface is often contacted with the wheel, namely, the phenomenon of wheel biting is commonly known. The occurrence of the phenomenon can cause the slide board to stop suddenly during the running process, and danger is easy to occur.

At present, the measures for preventing the sliding plate from biting the wheel include reducing the diameter of the wheel, adding a bridge pad, replacing the plate surface and adding a wheel shell. This affects the endurance of the skateboard, as the wheel diameter is reduced, and the passing ability thereof becomes worse. And the distance between the wheels and the board surface is increased when the bridge pad is additionally arranged, the bending amplitude of the front legs and the knees is larger during pedaling, and the physical power is consumed during pedaling. Similarly, the replacement of the board surface sacrifices the area of the board surface, and the space of footsteps is smaller. And finally, a wheel shell is additionally arranged to separate the plate surface and the wheels, but the interchangeability is not high, and the thickness of the wheel shell influences the turning radius.

Detailed Description

As shown in figure 1, the anti-biting wheel device of the sliding plate is arranged between a group of pulleys of the sliding plate and comprises a base 1, the top surface of the base is a plane, a prism 9 is led out from the bottom surface in an inclined mode, and because an included angle is formed between the prism and the top surface of the base, two spaces are formed in the bottom surface of the base and are respectively as follows: the inclined groove space 10 with an obtuse angle with the top surface of the base and the installation space 11 with an acute angle with the top surface of the base. A suspension 3 is arranged in a chute space 10 of the base 1, and the suspension 3 comprises a mounting part 12 which is arranged in the middle and used for being attached and connected with the prism and wing rods 13 which are symmetrically arranged on two sides of the mounting part. During installation, the installation part 12 is attached to the side wall of the prism in the chute space, and the wing rods 13 extend out of two sides of the base. The base is also provided with a bolt 2, and the bolt 2 penetrates through the prism at the installation space and the installation part 12 to connect the prism and the installation space. Two sides of the bolt 2 are respectively provided with an anti-biting wheel assembly 4, and an elastic gasket 5 is arranged between the anti-biting wheel assembly 4 and the suspension 3. Bolts 2 connect the suspension 3, anti-bite wheel assembly 4 and resilient spacer 5 to the base 1.

As shown in FIG. 2, six threaded holes are symmetrically distributed on two sides of the top surface of the base 1 and are used for being connected with the surface of the sliding plate.

As shown in fig. 3, the suspension 3 has a symmetrical structure. The left wing rod 13 and the right wing rod 13 are respectively connected with the wheels of the sliding plate, and the middle of the left wing rod and the right wing rod is provided with a round hole which is connected with the base 1 through a bolt 2. The top end of the mounting part 12 is provided with a head cylinder 3-1, the head cylinder 3-1 and the suspension 3 are integrated into a whole structure and are matched with the base 1, and the head cylinder 3-1 and the suspension 3 can rotate around the base 1, so that the steering of the skateboard is realized. The head cylinder 3-1 is in clearance fit with the round hole of the base 1. The suspension 3 acts on the elastic pad by the shift of the user's center of gravity, enabling the head cylinder 3-1 to rotate around the circular hole of the base 1 for steering. In the scheme, when external force is applied, the head cylinder 3-1 presses the elastic gasket, so that turning is slow, and the turning angle is fixed, so that the sliding plate is more suitable for being used by a sliding plate.

As shown in fig. 4 and 5, the anti-biting wheel assembly 4 comprises a limit bolt 6, a fixed housing 7 and a rubber sleeve 8. The fixed shell 7 consists of a cuboid groove 7-1 and two side ear plates 7-2, the cuboid groove 7-1 is sleeved on the end part of the prism 9, so that the limiting bolts 6 positioned on two sides of the cuboid groove 7-1 are also positioned on two sides of the prism 9 at the same time. The rubber sleeve 8 is arranged at the end part of the limiting bolt 6. As shown in fig. 4 and 5, the cuboid groove 7-1 is formed by hollowing out a cuboid from the top surface and the front surface, and a circular hole is formed in the side wall of the cuboid groove, which is attached to the base, and is connected with the base 1, the suspension 3 and the elastic gasket 5 through a bolt 2. The ear plates 7-2 on the left and right side surfaces of the cuboid groove 7-1 are symmetrically arranged. A threaded through hole is formed in the lug plate 7-2 and used for being connected with a limiting bolt 6, an acute angle included angle is formed between the axis of the threaded through hole and the side wall of the cuboid groove where the lug plate is located, after the limiting bolt 5 is obliquely arranged, in the turning process, the suspension 3 rotates to generate a rotating angle, and when the rubber sleeve 8 is in contact with the suspension 3, the contact surface is larger than the parallel contact surface, so that the work of the suspension is more stable. The extension length can be adjusted in fixed casing 7 to limit bolt 6, can change limit bolt 6 and the distance of suspension 3 and then realize the settlement of turning angle through adjusting length, and limit bolt 6's extension length accessible user self custom is adjusted, and limit bolt 6 stretches out and will make the limit angle of turning diminish more, and turning distance lengthens. The shorter the extension, the larger the turning limit angle. If the extension length is not proper, the phenomenon that the anti-biting wheel device does not work after biting the wheel can occur. During steering, the suspension 3 swings left and right to contact the limit bolt 6, so that the steering angle is limited. The rubber sleeve 8 can prevent the limit bolt 6 from directly contacting with the suspension 3, so that accidents can be caused when the vehicle turns and stops instantly. Meanwhile, when the sliding plate reaches the angle close to the wheel biting angle, the turning speed is slowed down and cannot be stopped immediately. For the user, the use feeling of the skateboard is not deteriorated, and the wheel biting phenomenon is prevented. The invention has simple structure and convenient assembly and disassembly, and improves the sliding safety.
