Description

The draw out switchgear cabinet is used door lock
Technical field
The utility model relates to the special door lock that a kind of draw out switchgear cabinet is used.
Background technology
At present the door lock of draw out switchgear cabinet commonly used generally can only be realized two functions no matter be with key or with handles: key or handle rotate to an angle, and dead bolt blocks tank bracket, and door is closed pinning; Key or handle rotate to an angle again, and dead bolt leaves tank bracket, and door can be opened.But, make the degree of protection of whole cabinet door be difficult to reach requirement because dead bolt does not have retraction function.In addition, handle also breaks away from from lock easily, influences the operation of door lock.
The utility model content
The technical problem that the utility model solved is to provide a kind of dead bolt to have retraction function, can improve the degree of protection of cabinet door, and the draw out switchgear cabinet that handle can not break away from from lock uses door lock, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of draw out switchgear cabinet is used door lock; Comprise that handle, lock shaft, spring, dead bolt and the lock that is fixedly connected with door-plate, said lock are fixed on the door-plate through nut, an end mounting spring of said lock shaft; End is fixedly connected with dead bolt through hold-down nut in addition; Be set with the fixed cover of band " L " shape sliding tray on the said lock shaft, be set with the turning set of band skewed slot on the said fixed cover again, the shank of said turning set and handle is pegged graft; Said lock shaft also is equipped with bearing pin, and the two ends of said bearing pin are stretched in the skewed slot of " L " shape sliding tray and turning set of fixed cover simultaneously; The shank of said handle is provided with groove; Be provided with centring ring in the said groove; On the embedding people lock inner ring in the corresponding groove, the shank of said handle is provided with sealing ring to said centring ring when mounted, and said sealing ring can prevent that sealing or dust get in the lock; Thereby avoid the part in the lock to get rusty, thereby can prolong the application life of door lock.
Beneficial effect: the utility model design principle is unique, and compact conformation is simple, and mechanical life is long, and function is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structure enlarged diagram of turning set among Fig. 1.
Fig. 3 is the structure enlarged diagram of fixed cover among Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of draw out switchgear cabinet is used door lock, comprises handle 1, lock shaft 7, spring 11, dead bolt 5 and the lock that is fixedly connected with door-plate 4; Said lock 4 is fixed on the door-plate through nut 12; One end mounting spring 11 of said lock shaft 7, end is fixedly connected with dead bolt 5 through hold-down nut 6 in addition, is set with the fixed cover 9 of band " L " shape sliding tray 14 on the said lock shaft 7; On fixed cover 9, be set with the turning set 10 of band skewed slot 13 again, and turning set 10 is pegged graft with the shank of handle 1; Said lock shaft 7 also is equipped with bearing pin 8, and the two ends of bearing pin 8 are stretched in the skewed slot 13 of " L " shape sliding tray 14 and turning set 10 of fixed cover 9 simultaneously; The shank of said handle 1 is provided with groove, in groove, is provided with centring ring 3, and this centring ring 3 is when mounted on embedding people lock 4 inner rings in the corresponding groove.
As shown in Figure 1, the shank of said handle 1 is provided with sealing ring 2, and said sealing ring 2 can prevent that sealing or dust get in the lock 4, thereby avoids the part in the lock 4 to get rusty, thereby can prolong the application life of door lock.
The operating principle of the utility model is following: when locking a door, and swing handle 1, handle 1 drives turning set 10 and rotates; Under the effect of bearing pin 8, turning set 10 drives lock shaft 7 and rotates, and lock shaft 7 drives the dead bolt 5 that is connected with it and rotates; Make dead bolt 5 stretch people's tank bracket, be rotated further handle 1, because bearing pin 8 slides in " L " shape sliding tray 14 of skewed slot of turning set 10 13 and fixed cover 9; The skewed slot 13 of turning set 10 and " L " shape sliding tray 14 of fixed cover 9 match, and bearing pin 8 is slided along particular trajectory, and bearing pin 9 drives the active force retraction that lock shaft 7 overcomes spring 11; Lock shaft 7 drives dead bolt 5 retractions again, thereby has realized the retraction function of dead bolt 5, and the stroke of retraction is by the length decision of pod; It is tightr that the retraction of dead bolt 5 can make sealing ring and the tank bracket on the cabinet door fit, and improved the degree of protection of whole cabinet door, and high energy reaches IP55.When opening the door, reverse rotation handle 1, handle 1 drive turning set 10 rotations; Turning set 10 drives bearing pin 8 and in " L " of fixed cover 9 shape sliding tray 14, slides, and bearing pin 7 sets back under the effect of spring 11, continues rotating handles 1; Turning set 10 drives bearing pin 7 rotations through bearing pin 8; Lock shaft 7 drives dead bolt 5 rotations, thereby makes dead bolt 5 break away from tank bracket, can open the door.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
