Abstract

The invention discloses a locker for a mobile radar antenna pedestal. The locker comprises a base, a taper pin boss, a shell, a first approach switch, a second approach switch, a cam mechanism, a knobdevice and a button device, wherein the base and the taper pin boss are a main body structure of the locker; the base and the taper pin boss are oppositely arranged; the shell is arranged on the base; the cam mechanism is arranged in the base and the shell; the knob device is arranged on a cam; the button device is connected to the inner side surface of a knob through a guide threaded pin; the cam is fixedly connected with a taper pin through a connecting rod and an adapter; the knob device and the cam synchronously rotate and drive expansion of the taper pin, thereby completing locking and unlocking actions between the base and the taper pin boss; the first approach switch is arranged at one side of the base; the second approach switch is arranged at one side of the taper pin boss; and alocking in-place signal and an unlocking in-place signal of the locker are provided through on / off of the approach switches. The locker is high in reliability and simple in operation.

Description

technical field [0001] The invention relates to the field of radar technology, in particular to a locking device for a mobile radar antenna base. Background technique [0002] As a common safety protection device for radar, the lock is mainly used to lock the rotating part of the antenna base when the radar is retracted, so as to prevent the radar equipment from moving due to the movement of the antenna base during the transfer of the radar equipment, causing the antenna and other surrounding areas to be damaged. Damage to the device due to impact. At present, the commonly used locking device for the mobile radar antenna base is the ordinary handle pin type. This type of locking device requires high positioning accuracy for the radar antenna base, otherwise it cannot be inserted and pulled out smoothly, and the reliability is low. Effective anti-loosening measures, bumps or vibrations during transportation and work may cause the latch to loosen, bringing safety hazards. C...
