The present invention is achieved through the following technical solutions: a bicycle front wheel support fast and stable parking device, which is composed of a pressure plate, a limit plate, a steel wire rope, a connecting rod I, a connecting rod II, a supporting device and a ball hinge foot seat. It is characterized in that: one end of the connecting rod II is connected to the support device, the other end of the connecting rod II is connected to one end of the connecting rod I, the other end of the connecting rod I is fixed to one end of the wire rope, and the other end of the wire rope is fixed to one end of the pressing plate, and the pressing plate Through the limit plate and connected with the limit plate, the ball hinge foot is fixed at the lower end of the supporting device.

The support device is composed of a support rod, a compression spring, a fixed guide cylinder and a limit screw, the compression spring is placed in the fixed guide cylinder, the support rod passes through the compression spring and is installed in the fixed guide cylinder, and the limit screw passes through The support rod is installed on the upper end of the fixed guide cylinder.

The ball hinge foot seat is composed of a ball screw, a ball socket and a cover plate, the ball end of the ball screw is installed in the ball socket, and the cover plate is fixed on the bottom of the ball socket.

Limiting grooves are processed on the limiting plate, the limiting plate is a frame structure, one side of the frame is a bent plate with mounting holes, and there are multiple limiting grooves on the other side of the frame.

The inner wall at the upper end of the fixed guide cylinder is processed with threads, and the diameter of the inner hole at the lower end is smaller than that at the upper end.

The limit screw is processed with a guide hole.

The upper end of the support rod is processed with a shaft shoulder, and the lower end is processed with a screw hole.

The supporting devices are installed in pairs.

One end of the ball head screw is a ball head, and the other end is processed with threads.

The advantage of the invention is that it can quickly and stably support the front wheel to park the bicycle. The limit plate is processed with a plurality of limit grooves, so that the length of the support rod can be adjusted on the one hand to adapt to bicycles with different diameters of the front wheel; on the other hand, the support rod can be lengthened when the ground is relatively soft Increase the stability; the ball hinge foot adopts the ball hinge method and is suitable for uneven ground; the inner wall of the upper end of the fixed guide cylinder is processed with threads, which is designed to facilitate the installation of limit screws; the inner wall of the lower end of the fixed guide cylinder The diameter of the hole is smaller than the diameter of the inner hole at the upper end, so the design is convenient for placing the compression spring; the limit screw is processed with a guide hole, so the design can play a role in guiding the movement direction of the support rod; the support devices are installed in pairs, so Two ball-hinge feet contacting the ground and the front wheel of the bicycle are designed to form a 3-point support, which is conducive to the stable parking of the bicycle with newspapers on the front frame; the support device is equipped with a compression spring, so that the design utilizes the shrinkage of the support rod back.

detailed description

A bicycle front wheel supporting fast and stable parking device is composed of a pressure plate 1, a limit plate 2, a wire rope 3, a connecting rod I4, a connecting rod II5 and a supporting device 6, and is characterized in that one end of the connecting rod II5 and the supporting device 6 connection, the other end of the connecting rod II5 is connected to one end of the connecting rod I4, the other end of the connecting rod I4 is fixed to one end of the wire rope 3, the other end of the wire rope 3 is fixed to one end of the pressure plate 1, and the pressure plate 1 passes through the limit plate 2 And it is connected with the limiting plate 2, and the ball hinge foot seat 7 is fixed on the lower end of the supporting device 6.

The support device is composed of a support rod 601, a compression spring 602, a fixed guide cylinder 603 and a limit screw 604. The compression spring 602 is placed in the fixed guide cylinder 603, and the support rod 601 is installed on the fixed guide through the compression spring 602. Inside the cylinder 603 , a limit screw 604 is installed on the upper end of the fixed guide cylinder 603 through the support rod 601 .

The ball hinge foot seat 7 is composed of a ball screw 701, a ball socket 702 and a cover plate 703, the ball end of the ball screw 701 is installed in the ball socket 702, and the cover plate 703 is fixed on the bottom of the ball socket 702 .
