Electric locking and unlocking mechanism

Abstract

The invention discloses an electric locking and unlocking mechanism which comprises a direct-current electromagnet, a moving mechanism, a spring, a threaded pressing block and an unfolded test plate. The moving mechanism and the direct-current electromagnet are mounted on two parallel and opposite sides of the unfolded test plate provided with a through hole through a guide sleeve respectively, a sliding sleeve is in threaded connection with an armature of the direct-current electromagnet on the other side through the through hole of the unfolded test plate, and the sliding sleeve is coaxial with the through hole of the unfolded test plate; the threaded pressing block mounted in the through hole of the unfolded test plate through a thread presses the spring on the sliding sleeve, the sliding sleeve receives pressure of the spring axially to clamp locking balls in ball holes of a ball frame, and the locking balls are fitted with a groove of a locking bolt to lock the locking bolt; a display system with a locking hole can be locked on the locking bolt by a locking nut. The direct-current electromagnet is selected as power, electric signals are taken as switch signals, uniform and accurate control on a test experiment of the display system can be realized through the electric locking and unlocking mechanism, and data collected by testing are accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and more specifically relates to an electric locking and unlocking mechanism, which is used for locking and unlocking when a product with an unfolding force is deployed for an unfolding test. Background technique [0002] According to the needs of product research and development, the locking and releasing functions of the official products of the display system are completed by the compression release device, and the compression release device is an pyrotechnic product. The system needs to be deployed several times after the production assembly is completed. Multiple test verifications, each time using pyrotechnics, will bring potential safety hazards and increase test costs. When testing the deployment time of the display system, the signal must be accurately collected, and the size of the original compression release device is relatively small, and the replacement product is limited by ...

[0002] According to the needs of product research and development, the locking and releasing functions of the official products of the display system are completed by the compression release device, and the compression release device is an pyrotechnic product. Multiple test verifications, each time using pyrotechnics for testing, will bring safety hazards and increase test costs

When testing the deployment time of the display system, the signal must be accurately collected, and the size of the original compression release device is relatively small, and the replacement product is limited by the installation space. The general locking and unlocking structure cannot become a qualified test replacement product
