Description
Technical field
A kind of spring bolt mechanism is the utility model is related to, particularly a kind of dead bolt telescoping mechanism, belongs to lockable mechanism technology neck
Domain.
Background technology
Dead bolt is common a kind of lockable mechanism in daily life and production, and dead bolt has various patterns, wherein most common
Be latch bolt, the latch bolt structure used at present is that one side be inclined-plane, and inclined-plane is plane to side, dead bolt rear portion setting coiling machine
Structure, when the inclined-plane of dead bolt during external stability mechanism with interacting, inclined-plane is by radial forces, and radial forces are because of inclined-plane
Act on to the axial direction of dead bolt and produce component, the component makes dead bolt bounce back, and after radial forces disappear, dead bolt is under the action of the spring
Resilience, plane block external fixation device, complete locking action.
Latch bolt structure is widely used due to simple in construction, easily manufactured, but one side is the latch bolt on inclined-plane at present
Structure, locking action can only be carried out from a direction, limit its application.
The content of the invention
The purpose of this utility model is, there is provided a kind of dead bolt telescoping mechanism, at least can be performed from both direction makes lock
The action that tongue is retracted, it can apply to need the occasion of multi-direction progress locking action.
To realize object above, the technical scheme that the utility model is taken is：A kind of dead bolt telescoping mechanism, the dead bolt are stretched
Contracting mechanism includes lock housing, dead bolt sliding block, dead bolt and spring, and using dead bolt direction as top, the lock housing is hollow for upper opening
Lock housing, the lock housing top edge are provided with position limiting structure, and dead bolt sliding block is located in lock housing, and dead bolt sliding block is set by lock housing top edge
Position limiting structure be limited in inside lock housing, be provided with compression spring between dead bolt sliding block lower surface and the lower wall of lock housing, dead bolt is slided
The lower surface of block and compression spring one end are inconsistent, and the other end of compression spring and the lower wall of lock housing are inconsistent, dead bolt sliding block with
Dead bolt is structure as a whole or is connected with each other structure, and dead bolt stretches out lock housing upwards, and a vertical plane is provided with dead bolt, with dead bolt
The axis that the geometric center of bottom surface is vertical is axis, and the opposite of vertical plane is by the inclined lock in lateral dead bolt axis outside dead bolt
Only inclined-plane, dead bolt also at least one prism vertical with locking inclined-plane；Further, the position limiting structure is housing top
The boss structure that edge extends internally；Further, the dead bolt has two prisms vertical with locking inclined-plane；Further,
The lock housing is rectangular hollow lock housing；Further, angle of bevel formed by the prism of the dead bolt and dead bolt bottom surface is 20
Spend between 75 degree.
Advantageous effects of the present utility model are：By setting one or two prism, Ke Yicong on dead bolt
Each prism, which performs, promotes dead bolt to make the action that it is retracted.
Brief description of the drawings
Fig. 1 is the internal structure schematic diagram of the utility model one embodiment.
Fig. 2 is the schematic diagram of the utility model one embodiment.
Embodiment
In order to more fully explain implementation of the present utility model, embodiment of the present utility model presented below, these realities
It is only to elaboration of the present utility model to apply example, does not limit the scope of the utility model.
With reference to accompanying drawing to the further details of explanation of the utility model, in accompanying drawing mark for：1. lock housing；2. dead bolt is slided
Block；3. boss；4. spring；5. dead bolt；6. prism A；7. locking inclined-plane；8. prism C；9. vertical plane.
As shown in the figure：A kind of dead bolt telescoping mechanism, the dead bolt telescoping mechanism include lock housing 1, dead bolt sliding block 2, the and of dead bolt 5
Spring 4, using dead bolt direction as top, lock housing 1 is the rectangular hollow lock housing of upper opening, and the top edge of lock housing 1 is provided with boss 3,
Dead bolt sliding block 2 is located in lock housing 1, and the upper surface of lock housing 1, which extends internally, boss 3, and the opening of lock housing upper surface is slided less than dead bolt
The upper surface size of block 2, therefore dead bolt sliding block 2 is limited in inside lock housing 1 by the boss 3 that lock housing top edge extends internally, dead bolt
Compression spring 4, lower surface and the one end of compression spring 4 of dead bolt sliding block 2 are provided between the lower wall of the lower surface of sliding block 2 and lock housing 1
Inconsistent, the other end and the lower wall of lock housing 1 of compression spring 4 are inconsistent, the upper surface of dead bolt sliding block 2 and the dead bolt 5 for stretching out lock housing
It is connected, when dead bolt 5 is by downward active force, spring 4 is compressed, and in the retraction lock housing 1 of dead bolt 5, is set on the present embodiment dead bolt
Put three inclined-planes, respectively prism A6, locking inclined-plane 7, prism C8, be additionally provided with vertical plane 9 on dead bolt.
As shown in figure 1, using the orientation in scheming as reference, when prism C8 is by the radial load of left, or locking inclined-plane 7
By the radial load of positive direction, or prism A6 by right radial load when, can produce the component for making dead bolt downward,
Make spring-compressed, dead bolt is reduced in lock housing, and when external force disappears, recoil of spring, dead bolt ejects lock housing again, and vertical plane 9 can be with
Outside retention mechanism locking, completes locking action.
Therefore, the execution locking when dead bolt of the present embodiment can perform three direction stress acts, and can be held with prism
Row promotes dead bolt to make the action that it is retracted
After embodiment of the present utility model is described in detail, one of ordinary skilled in the art is clearly understood that,
Above-mentioned claim is not departed from various change and modification can be carried out under spirit, it is all according to the technical essence of the utility model
Any simple modification, equivalent change and modification made to above example, the scope of technical solutions of the utility model is belonged to,
And the utility model is also not only restricted to the embodiment of example in specification.
