A self-locking handle device

Abstract

The invention discloses a self-locking handle device, which relates to the technical field of tight locks, and comprises a handle, a fixing seat, and a locking plate. The handle and the locking plate are respectively arranged on both sides of the fixing seat. A swivel seat is arranged between the seats, the handle and the swivel seat are movably connected by a first rubbing shaft, a movable shaft is arranged between the lock piece and the fixed seat, and the movable shaft runs through the fixed seat 1. Rotary seat, a first torsion spring is arranged between the fixed seat and the rotary seat, one end of the movable shaft is connected with the handle through a movable block, and the other end is movable with the locking plate through the second rubbing shaft connected, a second torsion spring is arranged on the second rubbing shaft, a spring is arranged on the periphery of the movable shaft, and one end of the spring stops at the sleeve of the rotating seat. The advantages of the present invention are that the structure is compact, the tightening effect is stable, and the handle also has an automatic return function, which does not hit the external box and cause no damage during the automatic return.

Description

technical field [0001] The invention relates to the technical field of snap locks, in particular to a self-locking handle device. Background technique [0002] With the development of industrial technology, the environmental requirements for sealed cabinets such as ovens, incubators, and low-temperature boxes are getting higher and higher. At present, the self-locking devices that are matched with them cannot meet the sealing requirements, resulting in unsatisfactory tightening effects and cannot be realized. The door is self-locking, the handle needs to be manually reset, and the sealing effect of the door body is not good, resulting in leakage accidents and other phenomena. Need a kind of self-locking handle device badly to solve the above-mentioned problem thus. Contents of the invention [0003] In view of the above-mentioned technical defects, the present invention provides a self-locking handle device, which solves the problems raised in the above-mentioned backgrou...
