Abstract
A one-tongue bearing lock is composed of a lock base and a lock cover covering the lock base. The lock base is internally provided with a spring bolt device and a lock cylinder device driving the spring bolt device to do retraction movement. The spring bolt device comprises an inclined spring bolt and a U-shaped frame. The inclined spring bolt is fixedly arranged on the U-shaped frame, and the spring bolt device is fixed inside the lock base through a conical spring. The lock cylinder device is composed of a lock cylinder and a rotating sheet fixing the lock cylinder. The outer edge of the rotating sheet extends outwards to form two hook sheets, and the two hook sheets are fixed on two frame bodies of the U-shaped frame in the spring bolt device respectively. The one-tongue bearing lock is simple in structure and reasonable in design, the structure of the lock cylinder device is symmetrical, the left sequence and right sequence do not exist, and installing is convenient. Meanwhile, a ball bearing is arranged inside the lock cylinder to enable the lock cylinder to rotate more smoothly and flexibly.
Description
Technical field
The utility model belongs to field of lockset, and what be specifically related to is a kind of use safety, has the lock body of certain pooling feature.
Background technology
The a lot of lock cores that exist on the market at present all need minute left and right directions to install, because the direction of opening the door has a minute left and right, so lock core is also had any different; Although on the doorframe that lock can use on the doorframe that on the left side opens the door or open the door in the right, all will be by oblique dead bolt conversion, therefore subsidiary function also will be changed, and to user, brings great inconvenience.
Summary of the invention
The purpose of this utility model is the deficiency for above technology, and a kind of single tongue bearing lock body of reasonable in design is provided.
The utility model is achieved through the following technical solutions: single tongue bearing lock body, by lock body base and the locking closure that is covered on lock body base, formed, in described lock body base, be provided with bolt device and drive bolt device to make the lock core device of stretching motion, this bolt device comprises oblique dead bolt and U-shaped frame, and tiltedly dead bolt is fixedly located on U-shaped frame, and bolt device is fixed in lock body base by volute spring.
Lock core device is comprised of the rotatable lamella of lock core, fixed lock core, and the outward flange extroversion of this rotatable lamella is extended two and hooked sheet, and these two hook sheet and are separately fixed on two frames of the U-shaped frame in bolt device.
In described lock core, be provided with ball bearing, can increase the rotation elasticity of lock core, lock core is rotated more smooth, extend the application life of lock core.
The rotation of lock core drives rotatable lamella to rotate, thereby makes the U-shaped frame being connected with the two hook sheets that extend on rotatable lamella make stretching motion, and then makes oblique dead bolt make stretching motion under the effect of volute spring and the motion of U-shaped frame.
The beneficial effects of the utility model embody and are: compared with prior art, the utility model is simple in structure, reasonable in design, by lock core device symmetrical configuration, and without left and right order, convenient installation; In lock core, ball bearing is set simultaneously, makes lock core rotation more smooth, flexibly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the bolt device schematic diagram in the utility model.
Following is the concrete title of each sign in figure: 1 bolt device, 2 volute springs, 3 lock body bases, 4 ball bearings, 5 lock cores, 6 rotatable lamellas, 101 U-shaped frames, 102 oblique dead bolts, 601 hook sheet.
The specific embodiment
As shown in Figure 1, single tongue bearing lock body, is comprised of lock body base 3 and the locking closure that is covered on lock body base 3, is provided with bolt device 1 and drives bolt device 1 to make the lock core device of stretching motion in described lock body base 3.
As shown in Figure 2, bolt device 1 comprises oblique dead bolt 102 and U-shaped frame 101, and tiltedly dead bolt 102 is fixedly located on U-shaped frame 101, and bolt device logical 1 is crossed volute spring 2 and is fixed in lock body base 3.
Lock core device is comprised of the rotatable lamella 6 of lock core 5, fixed lock core 5, and the outward flange extroversion of this rotatable lamella 6 is extended two and hooked sheet 601,602, and these two hook sheet 601,602 and are separately fixed on two frames of the U-shaped frame 101 in bolt device 1.
In described lock core 5, be provided with ball bearing 4, can increase the rotation elasticity of lock core 5, lock core 5 is rotated more smooth, extend the application life of lock core.
The rotation of lock core 5 drives rotatable lamella 6 to rotate, and makes the U-shaped frame 101 being connected with the two hook sheets 601,602 that extend on rotatable lamella 6 make stretching motion, and then makes oblique dead bolt 102 make stretching motion under the effect of volute spring 2 and 101 motions of U-shaped frame.
The utility model operating principle is: key is filled in lock core 2, key turns drives rotatable lamella 6 to rotate, by rotatable lamella 6, drive U-shaped frames 101 and the lock core 5 that is connected with U-shaped frame 101 is made stretching motion under the elastic reaction of volute spring 2, thereby realize, open the door and the object of closing the door; The utility model adopts single-bolt structure, and lock body is simpler, and in lock core, ball bearing is set, and lock core is rotated more freely smooth, the features such as prolongation in application life.
