Burglary-resistant lock based on spiral type reverse clutch module and double-motor module

Abstract

The invention provides a burglary-resistant lock based on a spiral type reverse clutch module and a double-motor module. The burglary-resistant lock is characterized by comprising a lock body module, the spiral type reverse clutch module and the double-motor module. The spiral type reverse clutch module comprises a lifting pin (207), a lifting pin spring (208), a lifting pin baffle ring (206), an inner handle rotating part (205), a square steel sleeve (204) and a transmission assembly. The double-motor module comprises a covering plate (301), two pinions (302), a gear shaft (303), a motor shell (304), two identical motors (305), a torsion spring (306), an arc push plate (307), a front push plate (308), a rear push plate (309) and a transverse rod (3010). The burglary-resistant lock is unlocked in a single direction, the lock body still can not be unlocked under the condition that a front panel is detached and the lock body is exposed, so that the safety of the lock is improved.

Description

technical field [0001] The invention belongs to the technical field of products, and in particular relates to a tamper-resistant lock based on a spiral back clutch module and a double motor module. Background technique [0002] At present, most of the clutch mechanisms of electronic door locks on the market are located on the front panel of the door lock or inside the lock body. The structure of the door lock with the clutch on the front panel is simple, but the front panel is damaged, and it is easy to open the door lock when the front panel is removed; the lock body of the door lock with the clutch inside the lock body is an electric lock body, and there is a signal on the lock body Wires, power supply lines, and the installation of the lock body are cumbersome, and due to the addition of electrical components, the reliability of the lock body decreases. In the prior art, the inner part of the lock is a force-bearing part that receives the action of opening and closing th...

Problems solved by technology

The structure of the door lock with the clutch on the front panel is simple, but the front panel is damaged, and it is easy to open the door lock when the front panel is removed; the lock body of the door lock with the clutch inside the lock body is an electric lock body, and there is a signal on the lock body Cables, power supply lines, the installation of the lock body is more troublesome, and due to the addition of electrical components, the reliability of the lock body is reduced

In the prior art, the inner part of the lock is a force-bearing part that receives the action of opening and closing the door. It is provided with a square force-bearing hole that is completely matched with the square steel. When the front panel is destroyed, the lock body is exposed, and the lock can be driven by turning the square steel. The parts in the body rotate to realize unlocking, so the lock body can be opened easily, and the security of the door lock is not high

Moreover, during the movement of the motor pushing plate in the prior art, since the top of the horizontal axis is a plane and has a large contact area with the spring wire, the cross bar may block the torsion spring spring wire, causing the motor to be unable to rotate, and the motor is stuck. burn out problem
