Description

Auxiliary device convenient to share bicycle removal behind lock

Technical Field

The invention relates to an auxiliary device convenient for sharing the movement of a bicycle after locking, and belongs to the field of vehicle maintenance and management.

Background

With the vigorous development of the internet industry, the concept of 'sharing economy' is deeply enjoyed, wherein the most representative sharing single vehicle is rapidly popularized in each major city of the whole country, and the problem of the last kilometer of daily travel of people is solved. However, due to disordered management and disordered placement of the shared bicycle, a large number of public resources are occupied, troubles are brought to citizens for traveling, and the frequency of traffic accidents is increased.

In order to standardize the placement of the shared bicycle, daily maintenance personnel are indispensable. When the vehicles are arranged, the shared bicycle is generally locked, when the shared bicycle is directly pushed, the static friction force between the wheels and the ground can be overcome only by large pushing force due to the fact that the rear wheels are blocked in operation, and in the process, the mesh wires on the spokes and the lock intermittently collide to send out 'clicking' noise to influence passing pedestrians. It is of course also possible to lift the rear wheels of the shared bicycle, but this is rarely done because of the extra weight that needs to be borne.

Disclosure of Invention

In order to reduce the working intensity of maintainers and avoid noise from affecting other persons, the invention discloses an auxiliary device which is convenient for a locked shared bicycle to move.

The technical scheme adopted by the invention is as follows: an auxiliary device convenient for movement of a locked shared bicycle comprises a main body, wherein a chuck is arranged at the upper part of the main body and is used for clamping a rear lower fork of a rear wheel of the shared bicycle; the chuck comprises an upper chuck fixed on the upper part of the main body and a lower chuck sliding on the main body; the lower part of the main body is provided with a telescopic rod, and the lower end of the telescopic rod is connected with an auxiliary wheel; the rear lower fork of the rear wheel of the shared bicycle is clamped through the clamping head, the height of the clamping head is adjusted through the telescopic rod, the rear wheel is suspended, and the front wheel of the shared bicycle and the auxiliary wheel at the lower end of the telescopic rod jointly realize the movement of the shared bicycle.

Further, the device comprises a clamping threaded rod, a clamping threaded pipe and a clamping hand wheel; the clamping threaded pipe is arranged at the upper part of the main body, and the relative position of the clamping threaded pipe and the main body in the vertical direction is kept unchanged; the upper end is connected with the clamping hand wheel, the lower end is in threaded connection with the clamping threaded rod, the lower end of the clamping threaded rod is fixedly connected with the lower chuck, when the clamping hand wheel is rotated, the clamping threaded pipe can be driven to rotate around the axis of the clamping threaded pipe, then the clamping threaded rod moves up and down under the action of threads, and the lower chuck is driven to move up or down.

Furthermore, a sliding groove is formed in the main body in the length direction of the main body, and the lower clamping head slides in the sliding groove.

Further, the shape of the sliding groove is dovetail type or round.

Further, the upper part of the clamping threaded pipe is provided with a circumferential convex edge, and the main body is provided with an accommodating space of the convex edge and used for limiting the vertical position of the clamping threaded pipe, so that the relative position of the clamping threaded pipe and the main body in the vertical direction is kept unchanged.

Furthermore, the lower end of the telescopic rod is provided with a horizontal wheel shaft, the auxiliary wheel is installed on the wheel shaft and freely rotates around the wheel shaft to replace the locked rear wheel of the shared bicycle to rotate.

Further, the telescopic rod is telescopic along the length direction of the main body.

Compared with the prior art, the invention has the beneficial effects that: the device can be easily fixed on the frame of the rear wheel of the sharing bicycle, and the locked rear wheel of the sharing bicycle is replaced by the auxiliary wheel, so that maintenance personnel of the sharing bicycle can conveniently move the sharing bicycle, the working intensity of the maintenance personnel is reduced, and meanwhile, the generation of previous unpleasant noise is avoided. The auxiliary moving device can also prevent the abrasion of the tire and the damage caused by the impact of the lock head and the spoke caused by the ground resistance, and the service life of the shared bicycle is prolonged. The device is also convenient to take down from the shared bicycle, and only the clamping hand wheel needs to be rotated reversely.
