A rack-and-pinion integrated door lock and a radar electronic equipment cabinet containing the same

Abstract

The invention discloses a rack-and-pinion integrated door lock and a radar electronic equipment cabinet containing the lock, which belongs to the technical field of radar cabinet heat dissipation. The rack-and-pinion integrated door lock includes: an up and down linear sliding mechanism, which is used to slide and install on the free end of the door; The assembly includes a body, a lock bar and a lock tongue. The lock bar rotates through the body and the two ends of the lock bar pass through the body respectively, and the lock tongue is connected to one end of the lock bar. There are multiple gears that correspond to each other. Setting, the gear is fixed on the other end of the lock bar, and the gear and the rack are adapted to mesh; any lock bar rotates to drive the gear connected to the lock bar to rotate, and the gear drives the up and down linear sliding mechanism to drive the other gears and the lock bar to rotate synchronously And make the lock tongue and the lock buckle structure fit and lock respectively. The rack-and-pinion integrated door lock of the present invention can prevent the door body from loosening due to mechanical vibration when subjected to mechanical vibration.

Description

technical field [0001] The invention relates to the technical field of radar cabinet heat dissipation, in particular to a rack-and-pinion integrated door lock and a radar electronic equipment cabinet containing the same. Background technique [0002] At present, radar electronic equipment cabinets are generally used to install various radar electronic equipment. There is usually no door lock on the radar electronic equipment cabinet to lock the door body and the housing. When it is subjected to mechanical vibration, it will loosen due to mechanical vibration, which will easily lead to unintended opening of the door and affect the normal use of the radar electronic equipment cabinet. [0003] Furthermore, the existing radar electronic equipment cabinets all adopt air-cooled heat dissipation, which cannot meet the heat dissipation requirements of devices with large heat generation. For example, a cradle-type cabinet refers to a cabinet with a cradle that can rotate around a f...

Problems solved by technology

[0002] At present, radar electronic equipment cabinets are generally used to install various radar electronic equipment. There is usually no door lock on the radar electronic equipment cabinet to lock the door body and the housing. When subjected to mechanical vibration, it will loosen due to mechanical vibration, which will easily lead to unintentional opening of the door and affect the normal use of the radar electronic equipment cabinet

[0003] Furthermore, the existing radar electronic equipment cabinets all adopt air-cooled heat dissipation methods, which cannot meet the heat dissipation requirements of devices with large heat generation

For example, a cradle-type cabinet refers to a cabinet with a cradle that can rotate around a fixed shaft on one side. Electronic equipment is installed in the cradle and the cabinet. It has a clear view of cables and discrete devices, convenient wiring, and very convenient maintenance. However, the fans in the cradle-type cabinet are arranged on the top of the cabinet and on the cradle. Although the air-cooled heat dissipation method can meet the ventilation and heat dissipation of general electronic equipment products, it cannot meet the heat dissipation requirements of devices with large heat generation, such as Unable to meet the heat dissipation requirements of VPX bus-based devices
