Description
Technical field
The utility model relates to lock structure, relates in particular to a kind of fire prevention passageway lock construction opening and closing by key.
Background technology
At present, the mode that its shutter door is locked in the fire prevention passageway of buying is on the market all to realize by handle, and switching process is simple and convenient, but does not possess simple key open locking function, improved so virtually danger coefficient, anyone can open or close door by handle.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of fire prevention passageway lock construction is provided, and has not only realized passageway lock function, also has advantages of anti-unlatching.
The technical scheme that the utility model adopts is as follows:
A kind of fire prevention passageway lock construction, comprise the lock body being connected to form by drain pan and lid shell, in a side device lock panel of described lock body, on described drain pan, install respectively that latch bolt is found a place to live in and multiple drive screw pin, one end that described latch bolt is found a place to live in connects latch bolt, the described latch bolt upper symmetrical mounting crotch of finding a place to live in, spring is wrapped at least one place drive screw pin, and the two ends of described spring are extended and connect with described crotch to described crotch; The left shift fork of returning apparatus and right shift fork on described drain pan.
Its further technical scheme is:
The other end bending that described latch bolt is found a place to live in extends to form baffle plate, and described baffle plate is found a place to live in vertical each other with described latch bolt;
One end of described left shift fork is stretched out described drain pan and is covered by outer panels, and one end of described right shift fork is stretched out described lid shell and covered by wainscot;
On described left shift fork and right shift fork, have for key operated lockhole, lockhole is circular, extends to form rectangular aperture in the periphery of lockhole, and rectangular aperture is communicated with described lockhole.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, utilize key to realize the relative motion of left shift fork and right shift fork, the baffle plate butt of finding a place to live in by each shift fork and latch bolt, latch bolt is got away and drive the displacement of latch bolt, thereby realize the switching of door, without utilizing handle, realized passageway lock function, possess again simple key open locking function, met customer demand.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As Fig. 1, shown in Fig. 2, a kind of fire prevention passageway lock construction, comprise the lock body being connected to form by drain pan 5 and lid shell 8, be positioned at a side device lock panel 1 of lock body, installing hole 101 is set on lock panel 1, be positioned at and on drain pan 5, install respectively latch bolt and find a place to live in 11 and multiple drive screw pin 4, latch bolt is found a place to live in and 11 is " U " shape, drive screw pin 4 is triangularly arranged, realize drain pan 5 and cover the affixed of shell 8 by drive screw pin 4 and securing member, find a place to live in one end of 11 of above-mentioned latch bolt connects latch bolt 2, latch bolt 2 the utility model in the time closing through-going device in lock panel 1, latch bolt 11 the other end bending of finding a place to live in extends to form baffle plate 1101, it is 11 vertical each other that baffle plate 1101 and latch bolt are found a place to live in.Be positioned at the latch bolt symmetrical mounting crotch 12 on 11 of finding a place to live in, spring 3 is wrapped on the drive screw pin 4 that a place is single layout, and the two ends of spring 3 are extended and connect with crotch 12 to described crotch 12; Returning apparatus left shift fork 6 and the right shift fork 7 of butt each other on drain pan 5.As shown in Figure 3, Figure 4, one end of left shift fork 6 is stretched out described drain pan 5 and is covered by outer panels 9, and one end of described right shift fork 7 is stretched out described lid shell 8 and covered by wainscot 10.On left shift fork 6 and right shift fork 7, have the lockhole 14 of opening for key 13, lockhole 14 is circular, extends to form rectangular aperture 141 in the periphery of lockhole 14, and rectangular aperture 141 is communicated with described lockhole 14.
Specific works process of the present utility model is as follows:
As shown in Figure 3, Figure 4, latch bolt 2 is because the effect of spring 3 is in stretching out state, by by key
13 stretch in left shift fork 6 or right shift fork 7, drive left shift fork 6 or right shift fork 7 to rotate by rotation key 13, as shown in Figure 1, left shift fork 6 or right shift fork 7 connect with baffle plate 1101 in rotation process, and the application of force drives baffle plate 1101 and latch bolt to find a place to live in 11 along the displacement of direction shown in arrow in Fig. 1, because latch bolt is found a place to live in and 11 is connected with latch bolt 2, therefore drive latch bolt 2 to inside contract, thereby realize operating personnel in Men Nei or the unlatching of opposite house outdoors, in latch bolt is found a place to live in 11 displacement process, crotch 12 is relative displacement the two ends application of force to spring 3 also, when operating personnel unclamp after the rotation of key 13, spring 3 promotes crotch 12 by elastic deformation and latch bolt finds a place to live in 11, thereby make latch bolt 2 stretch out and restPose.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
