CN2379558Y - Lock with automatic alarming - Google Patents

Abstract

The utility model discloses a lock with automatic alarming, comprising a lock core, a lock body and cylinders. The utility model is characterized in that mounting holes for a group of cylinders on the lock body are open, the position for each open mounting hole (cylinder hole) is provided with a microswitch connected with the triggering end of an alarm circuit, and the lock with automatic alarming composed of the components can trigger the alarm circuit when a key pushes cylinders which push and then close the microswitch. The utility model has the advantages of simple structure, convenient operation and being able to automatically alarm the user not forgetting to pull out the key, etc., and can be used as the automatic alarming prompting lock devices of cylinder locks like a safe lock, an anti-theft door lock, a door lock, etc.

Description

A kind of lock of warning automatically

The utility model relates to a kind of lockset, particularly a kind of lock of warning automatically.

Existing lockset, for example door lock, safety cabinet lock etc., the user forgets key in lock core as not noting regular meeting, and causes hidden danger.

The purpose of this utility model is to design a kind of lock of warning automatically, can warn automatically when key is forgotten in lock core, reminds the user to note.

The purpose of this utility model is achieved through the following technical solutions, comprise lock core, lock body and pellet shot from a slingshot, it is open it is characterized in that having at least the installing port of one group of pellet shot from a slingshot on lock body, open installing port place is provided with a microswitch, the frizzen of microswitch stretches into installing port and contacts with pellet shot from a slingshot, the contact of microswitch and the trigger end of warning circuit link, the common composition of the above-mentioned parts lock of warning automatically.Key inserts in the lock core, with pellet shot from a slingshot to extrapolation, pellet shot from a slingshot moves up from the open installing port of lock body, promotes microswitch and makes it closed, reports to the police thereby trigger warning circuit, automatically the prompting key is in lock core, do not forget and extract, extract key after, pellet shot from a slingshot loses outside motive force, microswitch is got back to the state of initial disconnection, and warning stops.

The utlity model has simple in structure, easy to use, can warn automatically and submit to the user to note not forgetting advantages such as extracting key.

The utility model has following accompanying drawing:

Fig. 1 lock construction schematic diagram of warning automatically

Fig. 2 warning circuit schematic diagram

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model structural representation, lock core 1, lock body 2 all can adopt existing safe-guard door lock, common door lock, cylinder locks such as safety cabinet lock, wherein one group of pellet shot from a slingshot 3 or two groups of adjacent pellet shot from a slingshot rear ends are open, the installing port 4 that is pellet shot from a slingshot on the lock body 2 is open, the installing port of all the other pellets shot from a slingshot is still identical with existing cylinder lock to be sealed, can be provided with spring (spring of existing pellet shot from a slingshot is hard) in the open pellet shot from a slingshot hole, also can be without spring, under normal circumstances (when key does not insert) its rear end is concordant with the pellet shot from a slingshot hole for the total length of pellet shot from a slingshot group in the pellet shot from a slingshot hole, to guarantee to have enough promotion strokes.Open pellet shot from a slingshot installing port (pellet shot from a slingshot aperture) locates to be provided with a microswitch 5, microswitch can adopt commercially available miniature microswitch, for example has the microswitch (also can adopt the constant open contact of a pair of midget relay as microswitch) of the thin bar 7 of thinner stretched into pellet shot from a slingshot installing port.The frizzen 7 of microswitch 5 stretches into installing port 4 and contacts with pellet shot from a slingshot 3, the trigger end of the contact of microswitch 5 and warning circuit 6 links, microswitch 5 will be fixed on place, pellet shot from a slingshot aperture, for example can weld, twist, bundle or fix with connector, its armature contact is answered as close as possible pellet shot from a slingshot aperture, the open pairing key of pellet shot from a slingshot should select the pellet shot from a slingshot of projection that the groove position of displacement is greatly upwards arranged, to guarantee the reliability of the utility model work.The contact of microswitch 5 can link by the trigger end of a prior art and a warning circuit 6, as long as key inserts lock core, pellet shot from a slingshot can make the microswitch closure, and warning circuit 6 just sends alarm signal, points out the user not forget and extracts key.The said warning circuit 6 of the utility model can directly adopt existing music door-bell, alarm etc., also can adopt making such as Music Clip, alarm chip or speech chip, suggestion voice such as typing in advance in the speech chip " key does not pull out; please note ", " door does not lock, please be good the key band ".This two classes technical scheme all belongs to the content of prior art, and the utility model is not described in detail this.

Fig. 2 is a kind of warning circuit cell schematics of Gong selecting for use, and circuit among the figure and element all can adopt scheme of the prior art.

Claims (2)

1. lock of warning automatically, comprise lock core (1), lock body (2) and pellet shot from a slingshot (3), it is open it is characterized in that having at least the installing port (4) of one group of pellet shot from a slingshot on lock body (2), open installing port (4) locates to be provided with a microswitch (5), the frizzen (7) of microswitch (5) stretches into installing port (4) and contacts with pellet shot from a slingshot, the trigger end of the contact of microswitch (5) and warning circuit (6) links, above-mentioned parts form by key promote pellet shot from a slingshot (3), pellet shot from a slingshot (3) thus promoting microswitch makes it the closed lock of warning automatically that triggers warning circuit (6).

2. the lock of warning automatically according to claim 1, it is open it is characterized in that having the installing port of two groups of adjacent pellets shot from a slingshot on lock body (2).
