Sliding sleeve type closed dropping-preventing assembly

Abstract

The invention discloses a sliding sleeve type closed dropping-preventing assembly. The sliding sleeve type closed dropping-preventing assembly comprises a sleeve clamped in a through hole formed in a panel. A sliding sleeve capable of moving axially is inserted into the sleeve. The sliding sleeve type closed dropping-preventing assembly further comprises a dropping-preventing screw penetrating through the sliding sleeve and the sleeve. A spring is connected to the dropping-preventing screw in a sleeving mode, and the two ends of the spring abut against the inner wall of the part, in the sliding sleeve, of the sleeve. According to the sliding sleeve type closed dropping-preventing assembly, the sliding sleeve mechanism design is adopted, and the freedom degree of the dropping-preventing screw on the X coordinate, the Y coordinate and the Z coordinate is controlled through the spring; the sliding sleeve closes the irregular space formed by the irregular appearance of the dropping-preventing screw and the panel, and the appearance tidiness of the panel is improved; when the dropping-preventing screw rotates, the contact surface is the surface of the sleeve, and the surface of the panel is protected against damage.

Description

technical field [0001] The invention relates to a connection assembly in the field of mechanical processing, in particular to a sliding sleeve type closed non-falling assembly. Background technique [0002] Non-falling screw connection is a widely used connection structure, especially for vehicle-mounted cabinets and combined products, which have high reliability requirements. At present, this type of products directly adopts ordinary non-falling screws. The fastening of the cabinet and its combinations will bring about the following problems: [0003] 1) Due to the rotational movement of ordinary non-falling screws during use, the finish paint of the composite panel in contact with it is seriously damaged; [0004] 2) When the contact surface of the combination panel sinks, the head of the ordinary non-falling screw sinks, the exposed part becomes shorter, and the operation is difficult when tightening the screw; [0005] 3) Ordinary non-falling screws are always in a fre...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a sliding sleeve type closed non-shedding component to solve the problems of the traditional non-shedding screw connection structure such as serious damage to the paint surface of the panel, difficult fastening operation caused by panel sagging, irregular appearance and high maintenance cost.
