Abstract
The utility model discloses an electromagnet used for a door lock, which is provided with an electromagnet (1) and an armature (2) arranged in the electromagnet. The electromagnet used for the door lock is characterized in that a helical guide slot (4) is arranged at the outer surface of the armature (2); and the helical guide slot (4) is internally provided with a jack screw (5) which is fixedly installed. The outstanding feature of the electromagnet used for the door lock is as follows: part of the forward force of the armature is offset by the jack screw in the guide slot at the outer surface of the armature, which leads the armature to move forward in a rotating way, thus not only reducing the speed of the armature properly, but also greatly reducing the forward impulsive force of the armature, reducing the noise and the damage to a lock pin, and prolonging the service life thereof.
Description
Technical field:
The utility model relates to a kind of push-and-pull linear pattern electromagnet, especially a kind of electromagnet with pooling feature that is applied on the door.
Background technology:
At present, the linear pattern drive unit that is applied on the door lock mostly is motor, and its shortcoming is restive, speed is slow, exists to lag behind, and is unfavorable for the switch of door lock, need increase mechanism separately and solve, make lock structure be tending towards complicated owing to the caused problem that shuts automatically that lags behind.Also utilize existing push-and-pull linear pattern electromagnet to substitute motor, though it has solved actuating speed problem slowly, but opposite is its excessive velocities, suitably do not cushion, not only can produce bigger noise, cause people's discomfort, but also lockset is had bigger impact force, use repeatedly and easily cause lockset to damage.
Summary of the invention:
The utility model provides a kind of actuating speed that is applied on the door lock suitable at the above-mentioned deficiency of prior art, has the electromagnet of pooling feature.
Technical solution of the present utility model is: a kind of electromagnet that is applied on the door lock, be provided with electromagnet and interior armature thereof, and be provided with the helical form guide groove at the external surface of armature, in guide groove, be provided with hard-wired jackscrew.
This electromagnet is mounted on the doorframe, is provided with the ejector pin head on the top of armature, and the ejector pin head is corresponding with the lock pin on being installed in door leaf.
The tail end of described electromagnet is provided with the armature protective sleeve, and jackscrew is fixedly mounted on the armature protective sleeve.
Outstanding feature of the present utility model is that the external surface at armature is provided with the helical form guide groove, offset a part of armature power forward by the jackscrew in the guide groove, make the armature rotation forward, not only suitably reduce the speed of armature, and reduced its impulse force forward greatly, reduced noise, reduced destruction, prolonged its application life lock pin.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1; a kind of electromagnet that is applied on the door lock is provided with electromagnet 1 and interior armature 2 thereof, and the tail end of electromagnet 1 is provided with armature protective sleeve 6; external surface at armature 2 is provided with helical form guide groove 4, is provided with the jackscrew 5 that is fixedly mounted on the armature protective sleeve 6 in guide groove 4.
This electromagnet is to be installed on the doorframe by connector 8, is provided with ejector pin head 3 on the top of armature 2, and the lockhole that ejector pin head 3 passes on the doorframe is corresponding with the lock pin 7 on being installed in door leaf.
