Abstract

The utility model relates to a bush for a skateboard, and in particular to a component which is arranged inside an assembling hole of a skateboard body and is supplied for a screw for locking a skateboard wheel seat to extend. The bush comprises a hollow cylinder body, wherein one side of the cylinder body is provided with a plurality of elastic arms which are arranged to have distance to each other in the axial direction, a free end at the inner side surface of the elastic arm is provided with an inner inclined surface, the outer side surface of the cylinder body is provided with a reversed hook which can be tightly pushed against the wall of the assembling hole, and when the screw extends into the bush, the elastic arms can be expanded outwards, so that the elastic arms are pushed against the wall of the assembling hole, and the bush can be tightly positioned inside the assembling hole; therefore, when the skateboard is collided, the screw inside the bush can still firmly lock the skateboard wheel seat and is free from dropping off the bush, thereby improving the application safety of the skateboard.

Description

The sleeve that is used for slide plate

Technical field

The utility model relates to a kind of sleeve that is used for slide plate, refers to a kind of sleeve that is arranged in the skateboard body and assists winding slide plate wheel seat especially.

Background technology

Conventional skateboard includes the wheel seat 91 that a plate body 90 and two has roller, and this plate body 90 is provided with joining hole 92, and this two wheel seat 91 is locked in the joining hole 92 by screw 93 and (seen also shown in Figure 5), further makes this two wheel seat 91 be positioned this plate body 90 bottom surfaces.

Yet skateboarding belongs to vigorous exercise, slide plate in use can be subjected to collision, screw 93 also can collide mutually with the hole wall of joining hole 92 simultaneously, add 93 the hardness of tightening up a screw greater than wooden slide plate, when so slide plate is subjected to clashing into, hard screw 93 is the hole wall of bump slide plate joining hole 92 directly, cause the aperture of these plate body 90 joining holes 92 to be subjected to the bump of screw 93 and to become big, and these slide plate joining hole 92 places are easy to generate the crack, therefore the degree of

screw

93 and 90 interlocks of this plate body can reduce, screw 93 is got loose (as shown in Figure 5) easily, cause the winding stability of 90 of wheel seat 91 and plate bodys not good, also can increase the danger that slide plate uses, so only utilize the mode of screw 93 lockings also dangerous between this plate body 90 and this two wheel seat 91.

The utility model content

The technical problems to be solved in the utility model is: a kind of sleeve that is used for slide plate is provided, improves the winding stability between the plate body and wheel seat in the conventional skateboard.

Technical solution of the present utility model is: a kind of sleeve that is used for slide plate is provided, and this sleeve provides screw to wear and wherein reaches the locking wheel seat in order in the joining hole that is installed in skateboard body, wherein:

This sleeve includes the cylindrical shell of a hollow form, and this cylindrical shell one end is formed with a plurality of axially protruding out and the elastic arm of annular arrangement, and the free end medial surface of these many elastic arms forms the interior inclined-plane towards outer incline, and this cylindrical shell lateral surface is provided with overhead kick.

In the aforesaid sleeve, the other end of the relative elastic arm of this cylindrical shell forms the ring flange of a radial projection.

In the aforesaid sleeve, this sleeve has two overhead kicks, and the radially corresponding position of cylindrical shell lateral surface is located in these two overhead kicks.

The utility model has the advantages that: when this sleeve is arranged in the joining hole of skateboard body, can provide the screw of winding slide plate wheel seat to stretch in this sleeve, wherein, the overhead kick meeting of this sleeve is closely against the hole wall of joining hole, make this sleeve firmly be connected in the joining hole, and when screw stretches in the sleeve, screw can be along interior inclined-plane applied thrust, make of the hole wall pushing and pressing of those elastic arms towards joining hole, allow be the state of urgent butt between the hole wall of this sleeve and joining hole, and then reach purpose shockproof and that improve connecting structure stability.

The specific embodiment

As shown in Figure 1, disclose the sleeve schematic diagram that is used for slide plate provided by the utility model, to shown in Figure 4, disclose the installing schematic diagram that is used for the sleeve of slide plate provided by the utility model for another Fig. 2.

This sleeve 1 includes the cylindrical shell 10 of a hollow form, these cylindrical shell 10 1 ends are formed with a plurality of elastic arms 11 that axially protrude out, and the other end is provided with the ring flange 12 of a radial projection, these a plurality of elastic arms 11 are that the mode of adopting annular arrangement is provided with, all be provided with inclined-plane 13 on the medial surface of these a plurality of elastic arm 11 free ends, inclined-plane 13 is the lateral surface inclinations towards elastic arm 11 free ends in being somebody's turn to do, form big footpath opening, these cylindrical shell 10 lateral surfaces are provided with overhead kick 14, in the utility model preferred embodiment, the radially corresponding position of these cylindrical shell 10 lateral surfaces is provided with two overhead kicks 14, and in addition, these cylindrical shell 10 lateral surfaces also can be provided with an overhead kick 14 around this cylindrical shell 10.

Wherein, this sleeve 1 is the member of a plastic material, this sleeve 1 is located in the joining hole 21 of skateboard body 20, provide screw 40 to wear group and locking slide plate wheel seat 30, this sleeve 1 is forced in the joining hole 21 of skateboard body 20, utilize this at least one overhead kick 14 to stretch in the hole wall of joining hole 21, this sleeve 1 is tight against to be positioned in the joining hole 21, screw 40 in order to locking slide plate wheel seat 30 can stretch in the sleeve 1, further slide plate wheel seat 30 is fixed in these skateboard body 20 bottom surfaces, and screw 40 is in the process of locking, the elastic arm 11 of sleeve 1 can be strutted (as shown in Figure 3) outward, elastic arm 11 is stretched in the hole wall of joining hole 21, and screw 40 also present the state that is tight against the location with sleeve 1.

In sum, the sleeve that is used for slide plate provided by the utility model can improve the connecting structure stability between screw 40 and joining hole 21 hole walls, make when slide plate is collided, screw 40 still can be by this sleeve 1 design and strong fix in joining hole 21, so the design of this sleeve 1 can reach shatter-proof and prevent the purpose that screw 40 gets loose, and can prevent that joining hole 21 hole walls from producing the crack.
