Anti-loosening spoke cap

Abstract

The utility model discloses an anti-loosening spoke cap which comprises a spoke cap body. The spoke cap is provided with a first threaded hole connected with the spoke in a matched mode. An inserting groove is formed in the upper end of the first threaded hole of the spoke cap, a second through threaded hole is formed in the inserting groove and the outer wall of the spoke cap, a friction strip is arranged in the inserting groove, a limiting groove in the back face of the friction strip is aligned with the second threaded hole, a screw is matched with the second threaded hole, and one end of the screw abuts against the interior of the limiting groove. The friction strips are arranged between the spoke caps and the spokes, the friction coefficient can be increased through the friction strips, and the friction strips are pressed and limited through the screws, so that displacement of the spoke caps and the spokes can be avoided, and the risk of rim deformation caused by loosening of the spokes is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of spokes, and in particular relates to an anti-loosening spoke cap. Background Art

[0002] One end of the spoke is hooked on the hub, and the other end is fixed to the rim through the spoke nipple. The spoke tension can be adjusted by twisting the spoke nipple. When the wheel is bumpy during daily riding, the spoke nipple and the spoke will shift, causing the spoke to become loose and the rim to deform. In order to prevent the spoke nipple and the spoke from shifting, an anti-loosening spoke nipple is provided. Utility Model Content

[0003] In view of this, the technical problem to be solved by the present invention is to provide a spoke nipple that prevents loosening, thereby solving the problem in the prior art that the spoke nipple and the spoke may shift.

[0004] In order to solve the above technical problems, the utility model discloses a spoke cap that prevents loosening, including: a spoke cap; a spoke cap having a threaded hole 1 that is connected to the spoke; a slot is provided at the upper end of the threaded hole 1 of the spoke cap, and a threaded hole 2 is provided through the slot and the outer wall of the spoke cap, a friction strip is provided in the slot, a limiting groove on the back of the friction strip is aligned with the threaded hole 2, a screw is matched with the threaded hole 2, and one end of the screw is against the limiting groove.

[0005] Furthermore, the side wall at the upper end of the spoke nipple has four planes.

[0006] Furthermore, the depth of the slot is greater than or equal to one third of the depth of the threaded hole.

[0007] Furthermore, the height of the friction strip is greater than the height of the slot.

[0008] Furthermore, the friction strip is made of nylon.

[0009] Compared with the existing technology, this application can achieve the following technical effects:

[0010] The utility model provides a friction strip between the spoke nipple and the spoke, which can increase the friction coefficient and press the friction strip to limit its position by means of screws, thereby preventing the spoke nipple and the spoke from shifting and reducing the risk of rim deformation caused by loose spokes.

[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 is a cross-sectional schematic diagram of a spoke nipple according to one embodiment of the present invention; Figure 2 yes Figure 1 Enlarged schematic diagram of point A in the middle.

[0019] A spoke nipple to prevent loosening, comprising: a spoke nipple 1; the spoke nipple 1 having a threaded hole 2 for mating with the spoke; a slot 3 is provided at the upper end of the threaded hole 2 of the spoke nipple 1, a threaded hole 2 4 is provided through the slot 3 and the outer wall of the spoke nipple 1, a friction strip 5 is provided in the slot 3, a limiting groove 6 on the back side of the friction strip 5 is aligned with the threaded hole 2 4, a screw 7 is mated with the threaded hole 2 4, and one end of the screw 7 is against the limiting groove 6.

[0020] The side wall at the upper end of the spoke cap 1 has four flat surfaces 8, which are convenient for clamping the spoke cap 1 adjuster; the depth of the slot 3 is greater than or equal to one-third of the depth of the threaded hole 2; the height of the friction strip 5 is greater than the height of the slot 3, and the friction strip 5 is made of nylon.

[0021] The utility model provides a friction strip 5 between the spoke nipple 1 and the spoke, which can increase the friction coefficient. The friction strip 5 generates friction with the threads on the spoke, and the friction strip 5 is pressed and limited by the screw 7, thereby avoiding displacement of the spoke nipple 1 and the spoke, and reducing the risk of rim deformation caused by loose spokes.

[0022] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
