Description

Automatically controlled lock bolt sleeve

The utility model relates to a kind of electronically controlled door lock system, especially a kind of automatically controlled lock bolt sleeve.

At present, hotel, hotel, hostel etc. are adorned on each door mostly with common built-in lock, insurance lock etc., the passenger will enter door and must take key oneself to open the door or carry key by waiter and go on behalf of opening the door to information desk, though also the someone designs electric control door lock, shortcoming such as can't open after the high and outage of complex structure, manufacturing cost but exist, thereby should not extensively promote.

For overcoming above-mentioned deficiency, the utility model provides a kind of automatically controlled lock bolt sleeve, and automatically controlled lock bolt sleeve is installed in lock bolt sleeve positions such as former common door lock, safety lock on the doorframe, and waiter can realize the purpose of opening the door for the passenger at information desk operation electronic control part.

The utility model is achieved in that it comprises block set, iron core, coil assembly, back-moving spring, armature, baffle plate and electronic control part, it is characterized in that: the front end in block set has a U type breach, come in and go out for dead bolt, with screw iron core is fixed on the block set bottom, be fixed with coil assembly in the iron core, inner core at iron core is provided with a groove, be equipped with back-moving spring in the groove, groove center is an iron mandrel, this leads directly in the centre bore of armature, front end at armature is screwed baffle plate, and armature and baffle plate can slidably reciprocate in block set along iron mandrel by back-moving spring.

Advantage of the present utility model is simple in structure, can make full use of the common built-in lock that was equipped with originally, safety lock etc., and the few spending of joint when having a power failure, also can be opened door with original key.

Describe the utility model below in conjunction with accompanying drawing and implement structure.

Fig. 1 is the utility model structural representation.

As shown in the figure, front end in block set 1 has a U type breach, come in and go out for dead bolt, iron core 2 is fixed on the bottom of block set 1 with screw, be fixed with coil assembly 3 in the iron core 2, iron core 2 inner cores have a groove, be equipped with back-moving spring 4 in the groove, groove center is an iron mandrel, this leads directly in the centre bore of armature 5, front end at armature 5 is screwed baffle plate 6, and armature 5 and baffle plate 6 can slidably reciprocate in block set 1 along iron mandrel by back-moving spring 4, connects electronic control part 7 at coil assembly 3 lead-in wires.

Its operating principle is: the automatically controlled dead bolt of the utility model is sleeved on original door lock (comprising door lock with knob, common door lock, safety lock) lock bolt sleeve position, when closing the door state, dead bolt is positioned at the U type breach of block set, when desiring to open, make coil assembly 3 energisings by electronic control part 7, and generation magnetic field, armature 5 is attracted by iron core 2, and hold baffle plate 6 to block set 1 basal sliding, the U type breach of block set 1 is vacated, Door-lock bolt ejects in door from indentation, there because of being subjected on the door spring-loaded elastic force effect, and door promptly is opened.
