Design of symmetrical four-finger lock claw lock box of manual symmetrical sliding rail

Abstract

The invention discloses design of a symmetrical four-finger locking claw locking box of a manual symmetrical sliding rail. The symmetrical four-finger locking claw locking box comprises a locking pin,a rivet, a reset spring, a locking box, a locking piece, clamping teeth, fixed holes, a through hole, bolts, a connecting plate, an upper sliding rail assembly, a lower sliding rail assembly and clamping grooves, wherein the locking box is movably installed between the upper sliding rail assembly and the lower sliding rail assembly, the fixed holes and the through hole are formed in the locking box in a penetrating mode, the locking pin is inserted into the through hole, the reset spring is connected to the locking pin in a sleeving mode, the locking piece is connected to the bottom end of the locking box, the clamping teeth are arranged on the locking piece, the clamping grooves are formed in the lower sliding rail assembly, and the locking box is installed in the lower sliding rail assembly through mutual clamping and limiting of the clamping teeth on the locking piece and the clamping grooves. According to the design, the single-piece four-claw design is adopted, the locking strength is increased while the weight is reduced, and the safety of a whole chair is greatly increased.

Description

technical field [0001] The invention relates to the technical field of slide rail locking mechanisms, in particular to a design of a manual symmetrical slide rail symmetrical four-finger pawl lock box. Background technique [0002] In order to meet the different needs of passengers of different sizes for the front and rear space of the seat back, it is necessary to adjust the seat back back and forth, and this process is realized by adjusting the position of the slide rail. At present, according to the source of the sliding rail to adjust the driving force, the sliding rail can be divided into two types: manual sliding rail and electric sliding rail. [0003] For the manual slide rail, when the seat back is adjusted back and forth, it is first necessary to unlock the upper slide rail and the lower slide rail through the drive of the unlocking mechanism, so that the two are in a state of relative movement. [0004] In the current market, manual slide rail locking mechanisms ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a symmetrical four-finger locking claw lock box design with a manual symmetrical slide rail, which adopts a single-piece four-claw design, improves the locking strength on the basis of weight reduction, and greatly improves the safety of the whole chair It solves the problem that the manual slide rail locking mechanism in the current market is mostly locked by double locking plates or pawls, but its light weight and strength cannot meet the needs of the current stage.
