Detailed Description

The present invention will be described in detail with reference to the drawings and specific embodiments, which are illustrative of the present invention and are not to be construed as limiting the present invention.

Example 1

As shown in fig. 1 to 3, a detachable wheel includes a fixed portion 1 and a detachable wheel portion 2, the detachable wheel portion 2 is fixedly connected to the fixed portion 1, the fixed portion 1 is fixed at the bottom of a draw-bar box, the detachable wheel portion 2 is provided with a shock-proof member 21, a steering member 22, a wheel assembly 23 and a connecting assembly 24, the shock-proof member 21 dampens the wheel assembly 23 in the vertical direction, the steering member 22 is connected to the wheel assembly 23, the connecting assembly 24 fixedly connects the detachable wheel portion 2 to the fixed portion 1, the steering member 22 provides a universal steering function, and the connecting rod 241 also serves as a rotating shaft of the universal steering function; the connecting assembly 24 comprises a connecting rod 241 with a raised head on the steering member 22 and a spring catch plate 242 on the fixed part 1, the connecting rod 241 being engaged with the spring catch plate 242.

The working principle is described in detail: during installation, the connecting rod 241 is inserted into the spring catch plate 242 of the fixing part 1, and the spring catch plate 242 locks the protruding head of the connecting rod 241. When disassembling, the spring catch plate 242 is simply slid back, and the spring catch plate 242 does not lock the protrusion of the connecting rod 241, so that the entire detachable wheel portion 2 can be taken out.

Specifically, the fixing portion 1 is provided with a limiting groove 11 and a fixing plate 12, the spring catch plate 242 freely moves in the limiting groove 11, and the fixing plate 12 prevents the spring catch plate 242 from popping out of the limiting groove 11. The spring catch plate 242 is provided with a bayonet 243, a top-contacting displacement groove 244, a top-contacting rod 245 and a restoring spring 246, the bayonet 243 is in top-contacting with the top-contacting displacement groove 244 through the top-contacting rod 245 to move left and right to catch the connecting rod 241, the restoring spring 246 is in top-contacting with the spring catch plate 242 to reset, and precisely, the restoring spring 246 is in top-contacting with the tail end of the limiting groove 11. In the operation, when the top touching rod 245 is pressed, the top touching rod 245 moves the top touching displacement slot 244 of the spring catch plate 242 (it is worth saying that the top of the top touching rod 245 is an inclined surface matching the inclined surface of the top touching displacement slot 244) towards the direction of the restoring spring 246, so that the bayonet 243 of the spring catch plate 242 is disengaged from the connecting rod 241, and the connecting rod 241 can be taken out. Similarly, when the top feeler lever 245 is released, the spring catch plate 242 returns to its original position by the action of the restoring spring 246.
