Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-5, the utility model relates to an electromagnetic lock with safety protection locking function, including fixed bolster 1, chase 5 and solenoid 3, solenoid 3 install in chase 5, chase 5 one end install fixed iron core 7, solenoid 3 in be provided with movable iron core 2 corresponding with fixed iron core 7, chase 5 inlay in fixed bolster 1, movable iron core 2's one end install spring 8, fixed bolster 1's both sides inside wall on be provided with reference column 10 who imbeds chase 5 lateral walls, chase 5 and fixed bolster 1 between link to each other through the screw 11 of both sides.

As an embodiment of the present invention, the fixing bracket 1 is an integral structure made of aluminum, and the positioning columns 10 on the inner side walls of the two sides of the fixing bracket 1 are arranged in a staggered manner, and simultaneously, the screws 11 on the side walls of the two sides of the fixing bracket 1 are arranged in a staggered manner.

One end lateral wall of movable iron core 2 on be provided with round draw-in groove 9 for with the spacing joint of spring 8, through draw-in groove 9 can be steadily fixed spring 8's one end, usually speaking spring 8's minor diameter end and draw-in groove 9 looks joint, and major diameter end withstands with upper cover 4 or solenoid 3, spring 8 can not drop under the environment of abominable like this yet.

One end of the coil 3 is connected with the iron frame 5 through the upper cover 4, so that the coil 3 can be fixed better, and the moving stability of the movable iron core 2 is improved.

The end of the movable iron core 2 opposite to the fixed iron core 7 is provided with a guide rod 6 axially penetrating through the fixed iron core 7, and the guide rod 6 can guide the movement of the movable iron core 2.

During assembly, the iron frame 5 is riveted with the fixed iron core 7, then the iron frame is installed in the coil 3 and then the upper cover 4 is riveted, the movable iron core 2 is riveted with the guide rod 6 and then the spring 8 is installed, then the fixed support 1 is assembled and then the positioning column 10 is used for positioning, and the positioning column 10 is used for positioning in a staggered mode, so that the relative position between the iron frame 5 and the fixed support 1 after positioning is fixed and cannot move, and then the two screws 11 are used for locking.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
