Abstract
A passage lock unlocking structure, it includes the plectrum, latch bolt, latch bolt spacer, the key that are located on lock body base and dials peach and dial peach location structure, and described plectrum is swung and is connected in lock body base by plectrum axle; This plectrum middle part can act on latch bolt spacer, bottom can with lock-out state under key dial peach and interact; Described key is dialled peach and is swung in lock body base.Locking under state at closing time like this, External Force Acting is in latch bolt, can make plectrum with latch bolt interlock act on key dials on peach, make to dial and just can make latch bolt be retracted in lock body base after peach release to continue to have closed the door, thereby whole lock can not broken, know about like this after lock construction, when passage lock is subject to external force under lock-out state, latch bolt still can be retracted into and in lock, realize release, thereby can improve the application life of passage lock and prevent mistake lock.
Description
Technical field
The utility model relates to a kind of passage lock being arranged on the door that often needs switch gate.
Background technology
Passage lock, typically refers to and is arranged on for many people while often coming in and going out repeatedly on the door of switch gate, and its correct use is such: first close the door and rotate key again and lock, operate handle again and open door in room while needing to open the door.Once but load onto and can't see it after door and whether lock due to passage lock, so just easily maloperation, first locks and closes the door.Yet current passage lock, once after locking, easily make whole lock break occurring fiercely to collide at closing time on latch bolt, so current passage lock in use easily damages, causes often replacing of needs.If develop a kind of situation of fragile lock when latch bolt still can be retracted into unlocking structure in lock and just can solve current passage lock maloperation while being subject to external force under lock-out state.
Summary of the invention
The purpose of this utility model is to be to overcome the deficiencies in the prior art, and a kind of more reasonable structure is provided, and while being subject to external force under lock-out state, latch bolt still can be retracted into the passage lock unlocking structure in lock, with this, improves the application life of passage lock.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A passage lock unlocking structure, it includes the plectrum, latch bolt, latch bolt spacer, the key that are located on lock body base and dials peach and dial peach location structure, and described plectrum is swung and is connected in lock body base by plectrum axle; This plectrum middle part can act on latch bolt spacer, bottom can with lock-out state under key dial peach and interact; Described key is dialled peach and is swung in lock body base.
In to the improvement project of above-mentioned passage lock unlocking structure, described group of peach location structure is spring, and its two ends are enclosed within respectively lock body base and key is dialled on the spring sleeve of peach.
In to the improvement project of above-mentioned passage lock unlocking structure, in described lock body base, be provided with the latch bolt back-moving spring that latch bolt is resetted outward.
Compared with prior art, the beneficial effects of the utility model are: owing to being provided with the plectrum that can link with latch bolt and dialling peach with the interactional key of plectrum in lock body base, locking under state at closing time like this, External Force Acting is in latch bolt, can make plectrum with latch bolt interlock act on key dials on peach, make to dial and just can make latch bolt be retracted in lock body base after peach release to continue to have closed the door, thereby whole lock can not broken, know about like this after lock construction, when passage lock is subject to external force under lock-out state, latch bolt still can be retracted into and in lock, realize release, thereby can improve the application life of passage lock and prevent mistake lock.
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
[accompanying drawing explanation]
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is assembling schematic diagram of the present utility model;
Fig. 3 is that the utility model is assembled into the schematic perspective view (lock-out state) after passage lock;
Fig. 4 is that the utility model is assembled into the front elevational schematic (unlocked state) after passage lock.
[specific embodiment]
The utility model is a kind of passage lock unlocking structure, as shown in Figure 1, 2, it includes the plectrum 5, latch bolt 6, latch bolt spacer 7, the key that are located on lock body base 1 and dials peach 8 and dial peach location structure 9, described plectrum 5 is swung and is connected in lock body base 1 by plectrum axle 10, and these plectrum 5 middle parts can act on latch bolt spacer 7; Described key is dialled peach 8 and is swung in lock body base, when it swings to lock-out state, can interact with plectrum bottom.After the utility model is installed in passage lock, when maloperation at closing time, as shown in Figure 3, the artificial key that uses is dialled peach 8 while being flapped toward plectrum bottom by key, at this moment it contacts with plectrum, next in the process of closing the door when doorframe is encountered on the inclined-plane of latch bolt 6, doorframe makes latch bolt 6 toward the interior slip of lock body base 1, at this moment the latch bolt spacer 7 being connected with latch bolt 6 swings plectrum 5, so plectrum 5 lower reaction are dialled on peach 8 at key, it resets to released state after the active force that has overcome group peach location structure 9, as shown in Figure 4, thereby can make whole latch bolt be retracted into that lock body base 1 is interior closes the door, and whole lock can not broken, know about like this after lock construction, when passage lock is subject to external force under lock-out state, latch bolt still can be retracted into and in lock, realize release, thereby can improve the application life of passage lock, and, can prevent mistake lock, because this relief structure is applied to after passage lock, just in case key is lost in room and while laying the key under the door unintentionally, owing to making latch bolt that power is delivered on plectrum under doorframe effect, plectrum makes again key dial peach 8 and reset to released state after the active force that has overcome group peach location structure 9, so at this moment just can open door, enters to bring back in time key and locks a door.
In the present embodiment, as shown in Figure 1, 2, dialling peach location structure 9 is springs, and its two ends are enclosed within respectively lock body base 1 and key is dialled on the spring sleeve 30 of peach 8.
Preferably, in described lock body base 1, be provided with the latch bolt back-moving spring 20 that latch bolt 6 is resetted outward.
Although reference above embodiment describes the utility model in detail, but it will be apparent to one skilled in the art that by the disclosure, and in the situation that do not depart from principle of the present utility model and the spiritual scope that described claim limits, can the utility model be made a variety of changes or be revised.Therefore, the detailed description of disclosure embodiment is only used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
