Novel height-adjusting device

Abstract

The invention discloses a buckle device with a safety belt multi-gear height adjusting function. The buckle device comprises a plate body, chutes, lock catches and a lock pin. Side protecting plates are arranged on the two sides of the plate body, and the adjusting lock catches are arranged in the middles of the side protecting plates at intervals. Triangular grooves are formed in the edges of thelock catches, and the tensile strength of the lock catches is improved. The chutes are formed in the inner sides of the side protecting plates, and sliding blocks are provided with the round-head long lock pins capable of automatically stretching out and drawing back through control by springs. The sliding blocks slide in the chutes, when the lock pins slide to the lock catches, the lock pins automatically drop into the lock catches, clamping is achieved, and certain height adjusting is completed. According to the buckle device, through multiple improved design of plates, the sliding blocks and the chutes, the body weight is greatly reduced, and the lightweight requirement is met; through the structure of the double-row lock catches, clamping is stable and firm, and positioning clamping pieces at the two ends are prevented from slipping out; the potential safety hazard is eliminated, the extreme value reaches, the problem that the structure of an existing height-adjusting device is complex is solved, and the high performance is achieved; and mounting and fixing are conducted through wing clamps, the universality is high, and a novel height-adjusting device is suitable for variousvehicle types.

Description

Technical field [0001] The invention belongs to the field of automobile accessories, and in particular relates to a multi-gear height adjustment device for automobile safety belts. Background technique [0002] The car seat belt multi-position height adjuster (also known as the guide rail), the body is a quasi-flat geometric hollow cuboid, the upper surface of which is a movable slider, and the slider is equipped with retractable locks and buttons. And connect the guide ring. In the traditional height-adjustment of safety belt, there is a row of buckles (locks) with sheet metal structure in the middle of the bottom plate of the main body of the high-profile, generally three. This kind of lock is a directly punched rectangular sheet metal buckle. The retractable lock set on the slider falls into the buckle when it slides to the lock, forming a "snap" that is snapped to complete the height adjustment . When a driving car suddenly stops, the inertial impulse will cause a great te...

AI Technical Summary

Problems solved by technology

When a moving car suddenly stops, the inertial force will cause a great stretching force on the buckle. Because it is a single row of buckles, the slider is prone to left and right deviation when sliding, and it is extremely extreme when it is suddenly subjected to a load. It is easy to produce side force, so that the buckle edge of the lock is easy to be damaged. At the same time, because the lock is a general sheet metal punching hole, the buckle edge of the lock is easy to bend or the entire bottom plate will be pulled and deformed by a sudden huge force, resulting in snapping. Ineffective, unable to implement security protection, resulting in security risks
