Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a wheel axle structure comprises a wheel 8, a front fork 9 and a locking screw rod 1, wherein a central shaft 2 positioned in the middle is integrally formed on the wheel 8, two symmetrical limiting grooves 3 are formed in the outer side wall of the central shaft 2, a through hole 4 is formed between the two limiting grooves 3, the positions of the two limiting grooves 3 positioned in the through hole 4 are sunken inwards to form a lantern ring, the lantern ring is attached to the inner ring of a bearing 5 when the bearing 5 is inserted into the limiting grooves, the bearing 5 is inserted into the limiting grooves 3, a shaft sleeve 6 is inserted into the inner side wall of the bearing 5, the front fork 9 is sleeved between the two shaft sleeves 6, the locking screw rod 1 sequentially penetrates through the front fork 9 and the shaft sleeve 6 from left to right to extend to the right end, a locking screw sleeve 7 is screwed on the outer side wall of the locking screw rod 1, the two bearings 5 are respectively inserted into the limiting grooves 3 during assembly, the shaft sleeve 6 is inserted into the bearing 5, the, and then carry on spacingly with the position in the spacing groove 3, then with through hole and axle sleeve 6 intercommunication on the front fork 9, will insert the through hole to the lock screw 1, to the lock screw 1 run through left end axle sleeve 6 and enter into through-hole 4 in, then enter into right-hand member axle sleeve 6 and wear out from the right-hand member through hole, will lock the swivel nut 7 and twist on locking screw 1, and then accomplish the equipment.
