Embodiment Construction

[0026] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0027] combine Figure 1-Figure 6 , the composition of the electromagnetic lock guard of the present invention includes an outer ring 1 fixed on the door, an inner cover 2 placed in the outer ring, a stopper pin 5 installed on the outer ring and acting as a limiter, and fixed on the door. The spacer 3 and the electromagnet 4 installed on the spacer have a hole corresponding to the extension shaft of the electromagnet on the outer ring, and the outer ring is a ring with a hole in the middle, and the electromagnet is connected to the power supply of the electronic remote control lock . There are 4 claws on the inner side of the outer ring, and the hole on the outer ring corresponding to the extension shaft of the electromagnet is opened on one of the claws, and the stop pin is fixed on the said hole There are 4 claws on the inside of the inner cover on one side of...

Abstract

The present invention provides an electromagnetic lock protector which comprises an external ring which is arranged at a door and is fixed firmly, an internal cover arranged in the external ring, a retaining pin which is arranged at the external ring and realizes the function of limiting the position, a gasket which is fixed on the door and an electromagnet which is arranged at the gasket. The external ring is provided with a hole which is corresponding to an electromagnet extended shaft. The external ring is a ring which is provided with a hole at the middle. The electromagnet is connected with a power supply of an electronic remote control lock. The electromagnetic lock protector is designed for the electronic remote control lock. Under the condition that the electromagnet is electrified, the internal cover realizes radial positioning, the external ring, the retaining pin and the electromagnet extended shaft limit the position and realize axial positioning, while a jack catch at theexternal ring is meshed with the jack catch at the internal cover, so as to realize the protection to a lock hole. Under the condition that the electromagnet is switched off, the internal cover can be rotated manually to be demounted from the external ring, so as to realize the unlocking action.

Description

(1) Technical field [0001] The invention relates to a small lock protection device. (2) Background technology [0002] Existing multiple lock guards are publicly used or reported, and the most widely used is a mechanical manual password lock guard. Its purpose is generally to protect the keyhole exposed to the outside daily, but the principle is different. [0003] The principle of the existing combination lock guard is that a combination lock protection device is installed on the outside of the double lock core, and the shielding sheet of the double lock hole can be unlocked and locked by the combination lock, so as to realize the protection of the lock hole. [0004] There is also a simple lock protection device, which uses the convex body inside the structure, the limit pin and the screw hole installed at the box mouth, and uses the hole-shaped key and the keyhole mandrel to switch and control the lock cylinder baffle to realize Protection for the keyhole. [0005] The...
