Labor-saving device used for repairing vacuum tire through rubber strip

Abstract

The invention relates to a labor-saving device used for repairing a vacuum tire through a rubber strip. The labor-saving device is mainly composed of a hand wheel, a trapezoidal self-locking lead screw, a transmission nut, an upper end cover, screws, nuts, a bolt, a connecting rod, a lower end cover, a connecting base, a plug, a shell, a handle, a fixed column, a rubber block and a rolling bearing. The rotating hand wheel drives the trapezoidal self-locking lead screw to rotate together, the trapezoidal self-locking lead screw converts rotating motion into feeding linear motion of the transmission nut through threads, the transmission nut and the connecting base are fixedly connected together through the connecting rod via the nuts, and the transmission nut, the connecting base and the plug are fixedly connected together to do feeding linear motion. Rotating motion of the hand wheel is converted into feeding linear motion of the plug, the rubber strip used for tire repairing is placed at the bottom of the plug, and therefore the rubber strip is fed into the crevasse of the vacuum tire, the function of repairing the tire through the rubber strip is realized, and the plug can be taken out by rotating the hand wheel in the opposite direction after tire repairing is completed.

Description

Technical field [0001] The present invention relates to the field of civilian machinery, and more particularly to a provincial power device for rubber strip repair empty tires. Background technique [0002] At present, when the car vacuum tire is tipping the tires, the tires used are often used, and the tire tires used are often pure manual cartridges, which typically need to use a relatively large strength to pull the strip by extracting in the external force. Under the action, it is sent to the break of the tire, so that the tire is realized; so it will cause the operator's labor burden overweight, and the use is extremely inconvenient; it may also cause the tire to be inaccurate or tire failure due to improper operation. There is a problem that the waste of the rubber strip is not aligned. It will also cause the conditions of the tires. The quality of the pure manual plugging the tire is uneven, which will bring an unsafe factor to the car. [0003] Therefore, it is necessary ...

AI Technical Summary

Problems solved by technology

[0002] At present, when car tubeless tires are pierced by sharp cones such as nails and need to be repaired, the rubber tire repair device used is usually a purely manual plug-in device, which usually requires a relatively large force to pull the rubber strip through the external force. Under the action of the tire, it is sent to the break of the tire to realize tire repair; so it will cause the operator's labor burden to be too heavy and extremely inconvenient to use; at the same time, it may cause inaccurate tire repair or tire repair errors due to improper operation posture, and then It causes the problem of wasting rubber strips, and at the same time, the position of the tire repair is not aligned, and it will also cause the situation of air leakage; the quality of pure manual plugging and repairing tires is uneven, which will bring unsafe factors to the driving of the car
