Example one

A wheel tool-free mounting structure is shown in figures 1-5 and comprises a wheel shaft 1, a wheel 2 penetrating through the wheel shaft 1 and a shaft cap 3 sleeved at the end of the wheel shaft 1, wherein a bayonet 11 is arranged at the position, close to the end, of the wheel shaft 1, a shaft hole 31 is arranged in the middle of the shaft cap 3, a first limiting portion 32 and a second limiting portion 33 are obliquely arranged on the inner side wall of the shaft cap 3, the first limiting portion 32 and the second limiting portion 33 are distributed in a staggered mode along the direction of the shaft hole 31, the first limiting portion 32 is matched with the bayonet 11 to axially limit the wheel shaft 1, the second limiting portion 33 abuts against the end face of the wheel shaft 1, and the end of the wheel shaft 1 is blocked between the first limiting portion 32 and the second limiting portion 33.

For the spacing shaft 1 of axial, prevent shaft 1 axial displacement, set up first spacing portion 32, first spacing portion 32 is the elasticity preforming, and the elasticity preforming is equipped with threely, gathers together the setting and sets up along the equidistant setting of 3 inside walls of hood along shaft hole 31 direction. During assembly, the elastic pressing sheet is clamped in the bayonet 11, so that the wheel shaft 1 is effectively prevented from moving along the axial direction.

In order to prevent the wheel 2 from coming off, the second limiting portion 33 is disposed on the axle cap 3, the second limiting portion 33 is an elastic pressing cover 332, and includes an elastic inclined portion 331 and a pressing cover 332, the elastic inclined portion 331 is disposed along the axial direction of the axle hole 31, the pressing cover 332 is disposed along the radial direction of the axle hole 31 in parallel, and one side of the pressing cover 332 facing the axle hole 31 is an arc surface. The number of the elastic inclined parts 331 is three, the number of the pressing covers 332 is correspondingly three, and each pressing cover 332 is fixed on each elastic inclined part 331 and distributed along the radial direction of the shaft hole 31. The end face of the wheel shaft 1 is abutted against the second limiting part 33, and the end part is limited between the first limiting part 32 and the second limiting part 33, so that the wheel 2 cannot be separated outwards, and the wheel is fixed firmly.

In order to facilitate the assembly of the shaft cap 3, the shaft cap 3 is further optimally designed, the included angle between the elastic pressing sheet and the wheel shaft 1 is b, the included angle between the elastic pressing cover 332 and the wheel shaft 1 is c, and b is more than or equal to 0 and less than or equal to c and less than or equal to 90 degrees. Therefore, the elastic pressing sheet is clamped in the bayonet 11, when an axial action force acts, the elastic pressing sheet is tightly propped against the direction of the shaft end 12 of the wheel shaft 1 and is not easy to be separated from the bayonet 11, the wheel cap is convenient to detach in the direction of the shaft body of the wheel shaft 1, a space for accommodating the end part of the wheel shaft 1 is formed between the elastic pressing sheet and the elastic pressing cover 332, and the end part of the wheel shaft 1 is limited and positioned; the elastic pressing sheet and the elastic gland 332 have elasticity, are self-adaptive to the axle 1 and can adapt to the size deviation of the axle 1.

As shown in fig. 5, the present embodiment is suitable for a lawn mower, so that the wheel 2 of the lawn mower does not need to be directly assembled by a manufacturer, but the axle cap 3 and the wheel 2 are packaged in the form of accessories, so as to save the mounting tools.
