Abstract
The utility model relates to a three-stage and four-direction lockset which is provided with a Y-shaped square tongue plate, wherein three equidistant grooves are arranged on the straight edge of the square tongue plate; a shifting element of a cam of a lock head can be inserted into a first groove; two oblique edges of the square tongue plate are respectively connected with an upper lock plate and a lower lock plate which are respectively connected with a push rod of a back lock plate assembly through a connecting plate. The cam of the lock head is rotated for three circles, which can cause the square tongue plate and a square tongue head to be respectively shifted for three stages; simultaneously; the upper lock plate, the lower lock plate and a back assembly can be driven to flex to form three stages, an upward direction, a downward direction, a front direction and a back direction. A user can flexibly select appropriate stages, and the safety of the lockset and a door can be ensured; the utility model is suitable for general doors and security doors for residences, units, etc.
Description
The utility model relates to a kind of lockset.
At present, the common dead bolt of known lockset can only shift out one grade of fixing length, and lockset only has an orientation simultaneously.The dead bolt of regular length lacks concerning the user flexibly to be selected, though dead bolt too short open the door lock a door all convenient and swift, safety inadequately; Dead bolt is oversize, though safety improves, the key of locking a door of opening the door will change a lot of circles, has increased trouble.Its safety of lockset that only has an orientation is obviously not as multi-faceted lockset.
The purpose of this utility model is, position, a kind of third gear four directions lockset is provided, and makes lockset have four orientation, and dead bolt has three gears, and the user can select the gear of dead bolt, the safety that improves lockset according to different needs.
The purpose of this utility model is achieved in that in the lockset of position, a kind of third gear four directions, has a square tongue spare that comprises bifurcation type side hyoplastron, have three road grooves on the straight flange of bifurcation type side hyoplastron, the width of three road grooves equates, and the distance between each groove also all equates.When the position of side's hyoplastron should make the rotational lock head cam, the shifting part of cam can be inserted in the nearest groove of distance side's tongue.Two hypotenuses at bifurcation type side hyoplastron are connected with the lower locking plate assembly with the upper lock plate assembly respectively with straight flange intersection point place, on the upper lock plate of upper lock plate assembly, have connecting hole, be connected with one side of the L type connecting plate of rear lock plate assembly, the another side of L type connecting plate then is connected with the rear push-rod of rear lock plate assembly.
The utility model also can structure same as described above make the lower locking plate assembly be connected with the rear lock plate assembly.
The utility model can also make upper lock plate assembly and lower locking plate assembly all be connected with separately rear lock plate assembly respectively with identical structure.
Owing to adopt above-mentioned each technical scheme, after key inserts the tapered end cam hole, during twist lock head cam one circle, in a groove of being opened on tongue spare bifurcation type side, the shifting part side of the being inserted into hyoplastron straight flange of cam, and the side's of promotion tongue shifts out one grade, a groove on this moment side's tongue spare and the square hyoplastron thereof is all pushed ahead, because the width of three road grooves and separation all equate, therefore the second road groove arrives the position of original a groove, continues the second circle rotating cam, and the cam shifting part is inserted in the second road groove, the side's of promotion tongue continues to be moved out to second grade, same the 3rd circle rotating cam, will the side's of making tongue and assembly be moved out to third gear, vice versa.Because dead bolt of the present utility model has three gears, makes the user can select required gear flexibly for use.For example go out in short-term or be in a hurry temporarily and go out, can select first gear for use, it is all convenient and swift to open the door like this, lock a door.If whole family's out on tours, visit friends and relatives, need lock a door several months a few days, then can select third gear, to guarantee safety.
Because two hypotenuses of the utility model bifurcation type side hyoplastron also link to each other with the lower locking plate assembly with the upper lock plate assembly respectively, one or two in the upper and lower jam plate assembly also links to each other with the rear lock plate assembly, shifting out or regaining along with square tongue spare like this, it is flexible up and down respectively to drive upper and lower jam plate assembly, when upper and lower jam plate stretches, flexible by connecting plate drive rear lock plate assembly and rear push-rod, thus realize that lockset has position, upper and lower, forward and backward four directions, has more increased the safety of lockset.Make the utility model reach the function of position, third gear four directions.
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is the structure chart of position, the utility model third gear four directions lockset
1. side's hyoplastrons, 2. upper lock plate assemblies, 3. lower locking plate assemblies, 4. rear lock plate assemblies, 5. upper lock plates, 6. connecting plates, 7. rear push-rods, 8. lower locking plates among the figure
In the embodiment of position, the utility model third gear four directions lockset shown in Figure 1, have the groove that width and slot pitch all equate on the straight flange of the bifurcation type side hyoplastron 1 of side's tongue spare, there is chamfering at the lower ending opening place, both sides of groove, so that the shifting part of tapered end cam be inserted into move outside promotion side's tongue in a groove after, can produce cell body easily, square tongue spare has the square tongue of three interlocks in the present embodiment, and they are connected with square hyoplastron 1.Two hypotenuses of side's hyoplastron 1 are connected with upper and lower jam plate assembly 2,3 respectively with straight flange intersection point place, in the present embodiment, on the upper and lower jam plate assembly 2,3. all have connecting hole on the lower locking plate 5,8, be connected with one side of the L type connecting plate 6 of two rear lock plate assemblies 4 respectively, the another side of L type connecting plate 6 then is connected with two rear push-rods 7 of two rear lock plate assemblies 4 respectively.
The utility model is applicable to the common door and the security door of residential houses, unit etc.
