[0008] 3. At present, one of the common skateboard structures is to assemble the support frame and the screw rod by inserting the pin, but this method will affect the aesthetics, and it is easy to fall off and fall out, which will affect the performance of the skateboard. safety
[0009] Therefore the assembling structure of the support frame of existing skateboard, screw rod (being skateboard wheel axle) is not yet perfect, really needs to be improved

Embodiment Construction
[0028] see figure 1 , figure 2 , image 3 As shown, the preferred embodiment of the present invention includes a support frame 10, a wheel shaft 20, and a fixed sleeve 30, wherein the fixed sleeve 30 is sleeved on the wheel shaft 20, and two thread directions are opposite to each other between the support frame 10 and the wheel shaft 20 ( For example, the screw joints of positive teeth and negative teeth) are connected to each other, that is, the loosening of one screw joint will cause the other screw joint to be tightened to produce a relative tightening effect (that is, reverse tightening), so that the axle can be rotated. The screw lock is fixed in the axle hole and will not move axially; accordingly, the skateboard has better stability, faster speed, safer use and high precision, low manufacturing cost, the skateboard wheel axle will not fall off, and the appearance More beautiful and other effects.

The invention provides an axle fixing structure for a skateboard, and aims to overcome the defects of the conventional assembling structure for a support frame of a skateboard and an axle of a skateboard wheel. The axle fixing structure comprises a support frame, an axle and a fixing sleeve, wherein two internal thread parts with opposite thread directions (such as positive teeth and negative teeth) are arranged in the axle hole of the support frame; the axle is provided with an axle external thread part and is sleeved with the fixing sleeve provided with a fixing sleeve external thread part; the axle external thread part and the fixing sleeve external thread part are in threaded connection with the two internal thread parts with opposite thread directions respectively; a relative screwing action (namely, reactive screwing) can be generated by the axle through two screw joints with opposite thread directions, namely, the other screw joint is screwed more tightly when one screw joint becomes loose, so that one end of the axle is fixedly screwed and locked in the axle hole and is prevented from moving in the axial direction. By adopting the axle fixing structure, the skateboard has the effects of higher stability, higher speed, high safety in use, high accuracy, low manufacturing cost, prevention of falling of the axle of the skateboard wheel, more attractive appearance and the like.
Description
technical field [0001] The present invention relates to the technical field of a skateboard, in particular, it refers to a skateboard wheel shaft that can be screw-locked and fixed on the skateboard support frame without moving axially, so that the skateboard has better stability, faster speed, and easier to use. The wheel shaft fixing structure of the skateboard is safer, has high precision, low manufacturing cost, does not fall off the wheel shaft of the skateboard wheel, and has a more beautiful appearance. Background technique [0002] Skateboard is a load-bearing structure that allows users to stand upright and use the user's feet to propel them to achieve mobility. Since the skateboard can use the body's inclination, swing, and even run-up to achieve the effect of sliding, so Skating can be used as a means of transportation or leisure, and at the same time, various difficult movements such as high-altitude flips in the nature of performances or competitions have been d...
