Intelligent and safe counter lock device

Abstract

The invention is suitable for the technical field of locomotive locks and provides an intelligent and safe counter lock device. The intelligent and safe counter lock device comprises a shell assemblyand a counter lock assembly. The shell assembly comprises a shell, a counter lock shaft hole and a counter lock limiting pillar, wherein the counter lock shaft hole is formed in the lower surface of an inner cavity of the shell. Due to the fact that a motor and a counter lock screw rod are arranged, the motor rotates through a motor gear at an output end, the motor gear is connected with a screw rod gear in an engaged manner, the counter lock screw rod is driven to rotate, a transmission sliding block slides in the counter lock screw rod, a counter lock spring bolt is pushed to slide, counterlock is controlled through the motor, and therefore operation is more convenient. Due to the arrangement of a clamping structure of the transmission sliding block and the counter lock spring bolt, theimpact force exerted on the counter lock spring bolt can be effectively reduced, unloading force protection is conducted on a transmission structure of the counter lock assembly, and the transmissionstructure is prevented from being damaged. Due to the fact that a limiting circuit breaker is arranged, the phenomenon that the motor is overloaded, and the counter lock structure is damaged is prevented, and overload protection on the motor is achieved.

Description

technical field [0001] The invention belongs to the technical field of locomotive locks, and in particular relates to an intelligent safety anti-lock device. Background technique [0002] Electronic door locks emerged with the development of electronic technology. They are incomparable to mechanical locks in terms of convenience of use, prevention of illegal opening, and intelligent management. Therefore, they are widely used in industries with high safety requirements. The common ones are mainly magnetic cards, IC cards, TM cards, and radio frequency card electronic door locks. [0003] The anti-lock structure of the original mechanical lock is connected with the transmission component. After being hit, the impact force will be transmitted to the transmission component, which will cause damage to the transmission screw. The existing electric lock has no motor overload protection. When the motor is not working normally, it will cause damage to the anti-lock structure. The o...

Problems solved by technology

[0004] The invention provides an intelligent safety anti-lock device, which aims to solve the problem that the anti-lock structure of the original mechanical lock is connected with the transmission assembly. After being hit, the impact force will be transmitted to the transmission assembly, which will make the transmission screw The existing electric locks do not have motor overload protection. When the motor is not working normally, it will cause damage to the anti-lock structure. The locomotive lock tongue has a simple structure and poor operating feeling. Rotating and falling, the handle will rotate up during the process of the bolt spring stretching, which is a problem of poor safety
