Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
It should be noted that, in the present utility model, terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings, and are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element of the present utility model must have a specific orientation, and thus should not be construed as limiting the present utility model.
Examples
Referring to fig. 1, 2 and 3, the utility model discloses a rim spoke connection structure, which comprises a spoke body 1, wherein one end of the spoke body 1 is provided with a tooth cap 3 detachably inserted into a spoke hole 21 of a rim 2, the tooth cap 3 comprises a connecting part 31 and a sinking part 32 which are connected up and down, the sinking part 32 is positioned in the spoke hole 21, the connecting part 31 is positioned above the spoke hole 21, the outer wall of the connecting part 31 is provided with a thread structure 33, the spoke body 1 is connected on the spoke hole 21 by matching with a nut 4, a positioning opening 34 is formed in the bottom surface of the sinking part 32 for positioning an external caliper, and when the nut 4 is prevented from rotating, the tooth cap 3 rotates along with the rotation of the nut 4, so that the connection firmness of the rim 2 and the spoke body 1 is affected.
The connecting portion 31 is in a cylindrical structure, so that the connecting portion is matched with the spoke hole 21 in structure, and the phenomenon that the tooth cap 3 is stressed unevenly in the spoke hole 21 in the riding process to cause breakage or loss of the spoke hole is prevented.
