Description
Technical field
The utility model relates to a kind of electric fixtures, relates in particular to a kind of door latch structure of door of switch cabinet.
Background technology
Existing switchboard, the door latch structure of its cabinet door is roughly such: on the flange of cabinet header and bottom, open two holes, then punching on the doorframe of cabinet door upper and lower, door lock comprises two locking bars vertically arranging, with be arranged on middle part and be connected the lock body of two locking bars, when with key at cabinet external door panel face during to lock body locking, then insert in the punching on doorframe in the hole that two locking bars move through respectively on cabinet door flange up and down, whole like this cabinet door has just been lockable.In releasing process, locking bar is shunk back to lock body direction, exits, thereby cabinet door is opened in the punching of locking bar from doorframe.
Although such structure can be locked cabinet door well, once be in an emergency and cannot find in time in the situation of key, with regard to being difficult to, the working condition of switchboard is controlled; Thereby easily result in greater loss.For fear of the generation of this situation, be badly in need of a kind of cabinet door lock structure of design, even if so that in case of emergency also can fast cabinet door be opened without key.
Utility model content
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of door latch structure of door of switch cabinet, simple in structure, also can in case of emergency fast cabinet door be opened, in time emergency is processed even without key.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of door latch structure of door of switch cabinet, comprise cabinet door, and at cabinet door middle part, lock body is installed, it is characterized in that: also comprise the locking bar that is arranged on respectively cabinet header and bottom; Described locking bar is arc-shaped flaky structure, and the width of locking bar passes through and reduce gradually, thereby makes one end of locking bar form stub end, and the other end forms little head end; Little head end at locking bar is provided with two rollers, and two rollers lay respectively at the both sides of locking bar, and is connected by a connecting axle that runs through locking bar; The diameter of described roller is greater than the width of the little head end of locking bar, and two rollers cover the microcephaly end of locking bar; Stub end at locking bar offers respectively a through hole near inner side and outside;
The through hole of the stub end inner side of described locking bar has by one the shaft support of turning and cabinet door is rotationally connected, and the outer side through hole of its stub end is connected with lock body by a connecting rod with rotating shaft, and described lock body drives locking bar that cabinet door is opened or closed by connecting rod.
Further, the through hole in the outside of locking bar stub end is between the through hole and stub end edge of inner side; Design, is more conducive to when closing cabinet door like this, and the cooperation (contact or be close to) inside the little head end of locking bar and doorframe, to close cabinet door better.
Compared with prior art, the utility model has the advantage of: simple in structure, because locking bar and cabinet door are rotationally connected, when emergency occurs, be firmly pulled outwardly cabinet door, can force locking bar to rotate, microcephaly's end of locking bar arranges roller, the more slip of edge locking bar end and doorframe, thus more easily in the situation that there is no key, fast cabinet door is not opened, in time emergency is processed, thereby reduce the loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of locking bar.
In figure: 1-cabinet door, 2-lock body, 3-locking bar, 4-roller, 5-support, 6-connecting rod.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2, a kind of door latch structure of door of switch cabinet, comprises cabinet door 1, at cabinet door 1 middle part, lock body 2 is installed.Also comprise the locking bar 3 that is arranged on respectively cabinet door 1 top and bottom; Described locking bar 3 is arc-shaped flaky structure, and the width of locking bar 3 passes through and reduce gradually, thereby makes one end of locking bar 3 form stub end, and the other end forms little head end.Little head end at locking bar 3 is provided with the both sides that two roller 4, two rollers 4 lay respectively at locking bar 3, and is connected by a connecting axle that runs through locking bar 3; The diameter of described roller 4 is greater than the width of locking bar 3 little head ends, and two rollers 4 cover the microcephaly end of locking bar 3.Stub end at locking bar 3 offers respectively a through hole near inner side and outside.
The through hole of the stub end inner side of described locking bar 3 has the shaft support of turning 5 by one and is rotationally connected with cabinet door 1, and the outer side through hole of its stub end is connected with lock body 2 by a connecting rod 6 with rotating shaft, and described lock body 2 drives locking bar 3 that cabinet door 1 is opened or closed by connecting rod 6.
The through hole in the outside of locking bar 3 stub ends is between the through hole and stub end edge of inner side; Design, is more conducive to when closing cabinet door 1 like this, and the cooperation (contact or be close to) inside the little head end of locking bar 3 and doorframe, to close cabinet door 1 better.
Because locking bar 3 and cabinet door 1 are rotationally connected, when emergency occurs, firmly be pulled outwardly cabinet door 1, can force locking bar 3 to rotate, microcephaly's end of locking bar 3 arranges roller 4, the more slip of edge locking bar 3 ends and doorframe, thus more easily in the situation that there is no key, fast cabinet door 1 is not opened, in time emergency is processed, thereby reduce the loss.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
