Abstract
The utility model relates to a door latch structure for an electric appliance switch box, which mainly comprises an outer frame, a pulling and buckling part and a latch locking part, wherein a transverse latch hole and a through hole are arranged on the outer frame. The latch locking part which is pushed by a spring is arranged on the latch hole, and a pin body which is penetrated with the pulling and buckling part is arranged in the through hole. When the pulling and buckling part is stressed and pulled downwards, inclined convex spiral threads arranged at the periphery of a bottom ring of the pulling and buckling part are just adhered to the inclined straight edge side of the concave edge of the latch locking part, and the latch locking part is driven to shrink inwards for disengaging from the position of buckling and locking the electric appliance switch. The opening of the electric appliance switch box is laborsaving and convenient, and the design of the external shape simple structure.
Description
The utility model relates to a kind of appliance switch box bolt structure.
Consult shown in subsequent figures 1 and 2, the main member of appliance switch box bolt structure commonly used comprises housing 11, pulls button portion 12, bolt-lock portion 13, latch 14 and spring 15.The recessed groove 111 bottom side edge of this housing 11 offer a central slotted eye 112, and central slotted eye 112 bottom surfaces are provided with a horizontal frame groove 113, and the bottom side of pulling button portion 12 forms concave arc 121, pull button portion 12 preceding root edges and establish two lugs 122 and a hook end 123.Then establish a slotted hole 131 and a projection 132 in the bolt-lock portion 13, with nose bar 133 blockings one spring 15 of bolt-lock portion 13.Bolt-lock portion 13 cards are organized in horizontal frame groove 113, to pull button portion 12 again and be mounted on recessed groove 111, must the align hole of housing 11, the hole on its lug 122, and fixing with latch 14, this hook end 123 of pulling button portion 12 is stuck in bolt-lock portion 13 slotted holes 131, moves to push bolt-lock portion.
Yet above-mentioned appliance switch box bolt structure commonly used has following shortcoming:
1, is left and right sides swing owing to pulling pulling of button portion 12, places eminence, staff to be not easy to touch and appliance switch box is standing, and turn to lift toward side again that then the bad application of force of one side is pulled the course of action that moves on the other hand and also had any problem.
2, each part configuration of Chang Yong appliance switch box bolt structure is all quite complicated, and the mode of combination is also comparatively difficult, complicated structure die sinking, manufacturing, assembling all have its degree of difficulty, and its cost of equipment is also higher, processing is also wasted time and energy, manufacturing cost is higher, and the market competitiveness also just reduces certainly.
In order to overcome above-mentioned shortcoming, the utility model purpose provides a kind of appliance switch box bolt structure, it pulls button portion extension rod is mode down to pull, just pulls the direction of institute's application of force for people's eminence, and the design of its bolt-lock portion can reach the action that bolt-lock portion straight line convergent-divergent moves padlock or releasing.Another purpose is that the appliance switch box bolt structure is made improvements, and makes its housing, pulls the contour structures simplicity of design of button portion and bolt-lock portion, makes easily.
The utility model appliance switch box bolt structure, it is to be located at the side of appliance switch box in order to the bolt-lock chamber door.Establish a horizontal keyhole on the housing of this bolt structure, the sunken groove that a through hole connects housing the place ahead is established in this horizontal keyhole the place ahead, and a bolt-lock portion that is subjected to spring push is set on the horizontal keyhole.The through hole of housing then holds with a shank wears the setting that group one is pulled button portion.This extension rod of pulling button portion then is dissolved in and falls in the groove, wherein, extension rod mat shank can be pulled swing up and down, be provided with oblique protruding lira base ring week pulling button portion, this oblique protruding lira just is resisted against the oblique straight edge side on bolt-lock portion depression limit, when the extension rod of pulling button portion is stressed when pulling downwards, oblique protruding lira then peak at oblique straight edge and force bolt-lock portion produce straight line in the motion of contracting, so that break away from the position of padlock appliance switch box, and opened appliance switch box, comparatively smoothly laborsaving.
The utility model appliance switch box bolt structure has following advantage:
1, appliance switch box generally all is arranged at eminence, preventing child's false touch, and if its with about pull appliance switch box keeper pull button portion, then be not inconsistent with its application of force direction, unlatching is had any problem.And bolt structure of the present utility model, it pulls button portion extension rod is mode down to pull, just pulls the direction of institute's application of force for people's eminence, is opened appliance switch box easily, comparatively smoothly laborsaving.
2, the utility model appliance switch box bolt structure, its housing, the contour structures design of pulling button portion and bolt-lock portion is all quite simple, no matter in die sinking, makes, and is all quite easy in the assembling, correspondingly lowered cost, and improved the market competitiveness greatly.
Following drawings and Examples will help further to illustrate structure of the present utility model, in the various distortion of doing not under the scope of the utility model creative spirit, modify and will use, and all should be included in scope of the present utility model.

Consult Fig. 3, shown in 4 and 5, the utility model appliance switch box bolt structure includes:
Bolt-lock portion 40, these bolt-lock portion 40 central appropriate locations have a depression 41, and the side of this depression 41 is designed to the side of the oblique straight edge 42 of tool;
The mode of its assembling is that the side of bolt-lock portion 40 falls into hole 43, and the spring 50 of can planting is pushed the bolt-lock portion 40 of cluster spring 50 in the horizontal keyhole 21 of housing 20 again, forms bolt-lock portion 40 and be able to do horizontal rectilinear motion in keyhole 21;
The convex 32 of button portion 30 is pulled in order to the group card by through hole 22 places of housing 20, these convex 32 side direction run through side direction two pore 24 mappings mutually of a slotted hole 34 and housing 20, pore 24 and slotted hole 34 insert groups one shank 51, and make pull button portion 30 and housing 20 must pin group one, laterally wear group because of shank 51 again and pull button portion 30, cause the extension rod 31 of pulling button portion 30 can present down the motion mode of rotation;
It mainly is the oblique protruding lira 33 that is setting on this convex of pulling button portion 30 32, when pulling button portion 30 assembling housings 20, be to snap in bolt-lock portion 40 depressions, 41 places, and with oblique straight edge 42 top cards, when hand is pulled the downward swing of the extension rod 31 of button portion 30, its oblique protruding lira 33 also peaks at oblique straight edge 42 with its gradually wide inclined-plane, breaks away from the bolt-lock action and make to contract in the bolt-lock portion 40.And decontrol extension rod 31 pull state the time, 50 contact bolt-locks of this spring portion, 40 extrapolations, and force oblique protruding lira 33 to be replied, and make extension rod 31 be able to reinstatement with its oblique straight edge 42.
