Description

Smooth sliding structure of operation Technical Field The utility model particularly relates to a sliding structure capable of running smoothly, and belongs to the technical field of automobile accessories. Background In the field of automobile manufacturing, an automobile door limiter is used as a key component for guaranteeing stability and safety in the opening and closing processes of an automobile door, and the performance quality of the automobile door limiter directly influences the use experience and the driving safety of a user. At present, a part of automobile door limiters adopt a nut sliding rail structure to realize the limiting and guiding functions, but the structure has obvious defects. The nut and the sliding groove have large contact area, so that the friction coefficient is increased, the nut slides unsmoothly when the vehicle door is opened, the transmission efficiency is reduced, the problems of blocking, abnormal sound and the like are generated, the use feeling of a user is influenced, meanwhile, the long-distance cantilever structure from the stay bar to the connecting point of the screw rod and the nut enables the nut to bear larger external force when the vehicle door is frequently opened and closed, the abrasion of the nut is accelerated, the service life of the limiter is shortened, in addition, the high assembly precision requirement caused by the large contact area between the nut and the sliding rail and between the nut and the screw rod is increased, the production difficulty and the cost are increased, the transmission is easy to be blocked due to the assembly error, and the potential safety hazards such as abnormal opening of the vehicle door can be caused in the driving process. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a sliding structure which runs smoothly so as to achieve the purposes of reducing abrasion and prolonging service life. The utility model provides a smooth and easy sliding structure of operation, includes the spout, have the slip passageway of seting up along its length direction in the spout, at the internally mounted of this slip passageway have slide and drive slide along the lead screw of slip passageway translation, the slide top surface is connected with the cantilever, be provided with the guide rail on the inner wall of spout, set up on the slide with the recess, the guide rail extends to the inside of recess. Further, the sliding seat is connected to the screw rod in a threaded manner. Further, a through hole is formed in the sliding seat, an inner thread is arranged on the inner wall of the through hole, and an inner thread matched with the outer thread is arranged on the outer wall of the screw rod. Further, the guide rail is arranged at the left side and the right side of the inner wall of the chute, and the guide rail extends along the length direction of the chute. Further, the grooves are symmetrically formed in the sliding seat, and the inner walls of the grooves are attached to the outer walls of the guide rails. Further, the inner wall of the groove is provided with a rounding angle, and the shape and the size of the guide rail are matched with the groove. Further, the cantilever is perpendicular to the screw rod. Further, the sliding seat is provided with a mounting groove, and the cantilever is mounted in the mounting groove. The beneficial effects are that: 1. according to the utility model, the contact form is changed from cylindrical large-surface sliding to sliding of the chute, so that the contact area is greatly reduced, and the friction coefficient is obviously reduced. The cooperation design of slide and guide rail, recess further reduces frictional resistance, makes the slide more smooth and easy stable, has avoided the card that leads to because of the friction is big in the traditional structure and has slipped unsmooth problem, has promoted transmission system's stability. 2. The utility model shortens the distance between the sliding groove and the stay bar, reduces the length of the cantilever, optimizes the force transmission path and ensures that the force of the sliding seat is more reasonable. Compared with the traditional structure, the external force born by the sliding seat is greatly reduced, the abrasion speed of the sliding seat, the guide rail and other parts is slowed down, the service life of the whole sliding mechanism is effectively prolonged, and the maintenance cost is reduced.
