Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As depicted in figs. 1 and 2, one side of the present utility model, there is provided a kind of foot wheel mounting structure, including support member
1 and castor, mounting hole 2 is provided with the support member 1, and the mounting rod 3 of the castor includes the He of the first bar segment 4 being connected with each other
Second bar segment 5, flexible positioning piece 6 is installed in first bar segment 4, the diameter of second bar segment 5 is more than first bar
Section 4 diameter, the mounting rod 3 by between the flexible positioning piece 6 and the mounting hole 2 and second bar segment 5 with
The installation matching relationship formed between the mounting hole 2 is fixed in the mounting hole 2.Preferably, the castor also includes rolling
Wheel portion 9, it is connected with the lower end of the mounting rod 3.Preferably, the flexible positioning piece 6 is interference fitted with the mounting hole 2, and
The radial clearance coordinated between second bar segment 5 and the mounting hole 2 be less than first bar segment 4 and the mounting hole 2 it
Between the radial clearance that coordinates, for example, the radial clearance coordinated between the second bar segment 5 and the mounting hole 2 can be 0.03-
Between 0.1mm, the optimal gap for 0.05mm, the problem of to avoid castor from rocking.
Preferably, it is located at the remote of second bar segment 5 formed with limiting section 7, the limiting section 7 on the mounting rod 3
The side of first bar segment 4.It is highly preferred that the length sum L1 of the length of first bar segment 4 and second bar segment 5 is small
In or equal to the mounting hole 2 depth L2, so, the positioning to mounting rod 3 can be realized in the height direction by locating part.
Preferably, the flexible positioning piece 6 contacts with the side wall of the mounting hole 2.Wherein, the mounting hole 2 in the present embodiment can be
Through hole can also be blind hole, and the openend of the blind hole is close to one end of second bar segment 5.
Preferably, the transition position between first bar segment 4 and second bar segment 5, which is formed as one, has tapered slope
Guide part 11, to play a part of guiding.Preferably, the foot wheel mounting structure also includes what is be connected with the support member 1
Reinforcement structure 12 (for example, reinforcement etc.), the reinforcement structure 12 is circumferentially disposed around the mounting hole 2, to improve installation
The intensity in hole 2, prevent from being torn during its circumferential stress.
Compared with conventional bolt-type castor of the prior art, castor of the present utility model uses flexible positioning piece 6 simultaneously
The mode coordinated with the second bar segment and mounting hole, can not only be installed in through hole, or in blind hole, so, it is ensured that
When the mounting rod 3 of castor is in mounting hole 2 of the inserting to support member, it is not easy, and there is more preferable radial equilibrium performance, carries
