Abstract
The utility model relates to an electrical control latch. The electrical control latch comprises a housing, wherein a latch rod (2), a latch rod sleeve (3) and an electromagnetic pin (4) are arranged inside the casing, the latch rod sleeve is fixed in the housing, a ring-shaped pin groove (2-1) is arranged at the tail part of the latch rod, the tail part of the latch rod extends into the latch rod sleeve, the head part of the latch rod extends out of the casing through a latch rod hole on the casing, the electromagnetic pin is positioned on the side surface of one end of the latch rod sleeve, and a pin head of the electromagnetic pin can be radically extended into the ring-shaped pin groove at the tail part of the latch rod, so as to achieve the locking. The electrical control latch is characterized in that the electromagnetic pin is added to the latch structure and used for controlling the opening of the latch rod to realize the electronic lockup of the latch rod, so that the electronic control of the locking of the latch is realized, and accordingly the safety of the latch is greatly improved. Moreover, the electrical control latch is further improved on the aspect that two travel switches are added in the latch structure and can be used for well transmitting the location information of the latch rod, so as to improve the reliability of the locking of the latch.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of automatically controlled bolt.
Background technology
Common bolt is usually used in fastening with a bolt or latch and closes large-scale double door.It has a latch lever, latch lever is contained in the latch lever cover for seat, the latch lever cover for seat is installed on the Yishanmen, on the Yishanmen door bolt nose is housed in addition, have a handle on the described latch lever, pulling handle can make latch lever cross out its cover for seat and enters in the door bolt nose of opposite side door leaf, shake hands with the padlock locking again, thereby realize that two fan the locking of door.This bolt is compared with advanced at present electric control door lock, its poor stability, and also when the important safety occasion was used, it can not provide the status information of door lock, therefore, was difficult to provide safety guarantee preferably.
The utility model content
The purpose of this utility model is at the problem in the prior art, and a kind of automatically controlled bolt is provided, thereby the safety of bolt is improved greatly.
For achieving the above object, the technical solution of the utility model is:
It comprises a shell, in this shell, be provided with latch lever, latch lever cover and electromagnetism pin, described latch lever cover is fixed in the shell, the afterbody of described latch lever is provided with annular cotter way, the afterbody of described latch lever stretches in the latch lever cover, the head of described latch lever stretches out shell by the latch lever hole on the shell, and described electromagnetism pin is positioned at the side that latch lever overlaps an end, and its pin head can radially pass latch lever cover sidewall and stretches in the annular cotter way of latch lever afterbody and form locking.
The further improved technical scheme of the utility model is as follows:
Tail end at described electromagnetism pin is provided with first travel switch, is provided with second travel switch in the side of the described latch lever cover other end.
The utility model characteristics are to have added the electromagnetism pin in bolt structure, and control the unlatching of latch lever by the electromagnetism pin, thereby latch lever has been realized automatically controlled locking, and its safety improves greatly.The further improved characteristics of the utility model are to have added two travel switches in bolt structure, can transmit the status information of latch lever preferably with these two travel switches, thereby improve the reliability of bolt locking.Simultaneously, the utility model also has simple in structure, the easy characteristics of realization.
Description of drawings
Accompanying drawing, overall structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, this automatically controlled bolt comprises a shell 1, in this shell 1, be provided with latch lever 2, latch lever cover 3 and electromagnetism pin 4, described latch lever cover 3 is fixed in the shell 1, the afterbody of latch lever 2 is provided with annular cotter way 2-1, the afterbody of described latch lever 2 stretches in the latch lever cover 3, the head of described latch lever 2 stretches out shell by the latch lever hole 1-1 on the shell, described electromagnetism pin 4 is positioned at the side that latch lever overlaps 3 one ends, and its pin head can pass latch lever cover sidewall and stretch into and form locking among the annular cotter way 2-1 of latch lever afterbody, tail end at described electromagnetism pin 4 is provided with first travel switch 5, is provided with second travel switch 6 in the side of the described latch lever cover other end; Described first travel switch 5 and second travel switch 6 all can adopt microswitch, and wherein second travel switch 6 is the microswitch of a band roller.
The course of work of this automatically controlled bolt is: the handle 2-2 on the pulling latch lever, make latch lever 2 to locked position, position shown in promptly illustrating, then electromagnetism pin 4 stretches under the effect of its back-moving spring 4-1 among the annular cotter way 2-1 on the latch lever, make the latch lever 2 can not rollback and realize breech lock, at this moment, because of protracting of electromagnetism pin 4 discharges first travel switch 5, simultaneously, also because of not being subjected to compressing of latch lever to be in release conditions, then two travel switches provide the off-state signal to second travel switch, that is to say, when detecting two switches and be in off-state, illustrate that latch lever is in normal latch mode; When unblanking, need to provide unlocking signal by the controller 7 (this controller can adopt various electronic control modes such as modes such as fingerprint, induction or remote control) of this automatically controlled bolt, make electromagnetic lock 4 retraction and from annular cotter way 2-1, withdraw from, spur handle 2-2 again, latch lever 2 is retracted in the shell, promptly realize opening; When latch lever 2 was in lockset position of coupler, the latch lever wall withstood electromagnetism pin 4, made the electromagnetism pin be in advanced position, and at this moment, the afterbody of electromagnetism pin compresses first travel switch 5, makes its connection, and simultaneously, the afterbody of latch lever 2 also compresses second travel switch 6, makes its connection; That is to say, when detecting two switches 5,6 and be in on-state, illustrate that latch lever is in opening, if two switches are in the state of a connection, a disconnection, breech lock or unlatching that latch lever is described are in situation not in place, can give alarm signal by controller, also can be for Long-distance Control provide information, this application that electric controlled door is latched in vital areas such as storehouse, prison is very important.
