A rotary locking type door lock for a temperature control box comprises a lock cylinder (1) and a spring bolt (2). The rotary locking type door lock for the temperature control box is characterized in that the lock cylinder (1) comprises a lock shell (11), a steel ball holding sleeve (12), a rotary locking lining (13) and at least three steel balls (14); the rotary locking lining (13) and the steel ball holding sleeve (12) are coaxially arranged in a sleeved manner and are rotationally arranged; the inner wall of the rotary locking lining (13) is provided with a pressing effect arc face (131) acting on the steel balls (14); the spring bolt (2) comprises a spring bolt column (21), a center adjusting base (22) and a center adjusting spring (23); the head portion of the spring bolt column (21) and the steel ball holding sleeve (12) of the lock cylinder (1) are correspondingly matched in a nested manner; and the head portion of the spring bolt column (21) is provided with a locking bevel (2111) matched with the steel balls (14). The rotary locking type door lock for the temperature control box has certain door closing pulling force, is free is installation position and can completely meet the requirement of the temperature control box for the door lock.
Description
technical field [0001] The invention relates to a mechanical environment test equipment, in particular to a door lock structure of a temperature control box. Background technique [0002] The three-comprehensive vibration test system is the equipment for the comprehensive mechanical environment test of temperature and vibration on the product. It is to investigate the influence of vibration and temperature changes on electronic products during transportation, storage and use. [0003] The traditional three-integrated vibration test system includes a temperature control box and an electric vibration table. The temperature control box requires a door lock with a certain door closing force because of its door sealing requirements. [0004] Traditional temperature control box door locks generally use finished mechanical locks or adjustable quick hasp locks. In industrial hardware companies, although door locks can also be changed according to user requirements (for example: loc...
