Abstract
The utility model discloses a drawer switch cabinet door explosion-protection structure comprising a cabinet door, and the drawer switch cabinet door explosion-protection structure further comprises a circular pressing cap and a connecting rod connected with the pressing cap. One end of the connecting rod is fixedly connected with the pressing cap, and the other end of the connecting rod penetrates the cabinet door from an outer side of the cabinet door to extend into a cabinet body; the end, extending into the cabinet body, of the connecting rod is provided with a locking plate; one end of the locking plate is fixedly connected with the connecting rod through a bolt, and the other end of the locking plate is bent in the direction away from the pressing cap firstly and then bents in the direction away from the connecting rod so that the whole locking plate is Z-shaped; and a reset spring is further disposed between the pressing cap and the cabinet door, and the reset spring is sleeved on the connecting rod. The drawer switch cabinet door explosion-protection structure is simple in structure and can effectively prevent a switch cabinet from explosion so that the drawer switch cabinet door explosion-protection structure is high in safety.
Description
Technical field
The utility model relates to a kind of electric equipment, relates in particular to a kind of drawer of switch cabinet door blast resistance construction.
Background technology
Switch cubicle is very extensive in the use of high-rise commercial mansion and high-rise residential building, therefore require lock for door of switch cabinet fail safe higher, but because traditional lock for door of switch cabinet is by after switch cubicle locking, between the cabinet door of switch cubicle and cabinet, form and coordinate closely, in the cabinet that the electric arc producing when switch cubicle especially high-tension switch cabinet is worked like this causes, air expands and causes blast to wait and cabinet door is washed open with regard to being easy to, abnormally dangerous.Although people have adopted multiple means, such as adopting multi-point lock, high strength lock etc. to carry out the locking of cabinet door, but very trouble is so not only installed, and also causes cost very high, meanwhile, so also fundamentally not solving the blast situation causing because of electric arc in cabinet occurs.
Utility model content
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of drawer of switch cabinet door blast resistance construction, simple in structure, can effectively prevent that switch cubicle from blasting, safe.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of drawer of switch cabinet door blast resistance construction, comprise cabinet door, it is characterized in that: also comprise a circular pressure cap and the connecting rod being connected with pressure cap, one end of described connecting rod is fixedly connected with pressure cap, and the other end runs through cabinet door from the outside of cabinet door and stretches in cabinet; One end of stretching into cabinet at connecting rod is provided with a locking plate; One end of described locking plate is fixedly connected with connecting rod by bolt, the other end first bends to the direction that deviates from connecting rod to the direction bending that deviates from pressure cap again, make whole locking plate be " Z " shape, this locking plate can be under the drive of pressure cap along the axial motion of connecting rod and rotate with pressure cap; Between pressure cap and cabinet door, be also provided with a back-moving spring, described back-moving spring sheathed with connecting rod on.
The utility model can be locked cabinet door and cabinet by locking plate and coordinating of doorframe, and locking plate is " Z " shape, and locking plate directly coordinates with inside doorframe; During installation, without offer locking plate hole on doorframe, make easier for installation, quick; Under the effect of back-moving spring, locking plate and cabinet door fit tightly all the time, and locking effect is good.While causing air to expand when cabinet internal cause generation electric arc, in cabinet, air is exerted pressure to cabinet door, force cabinet door outwards to move, owing to thering is back-moving spring between cabinet door and pressure cap, now, cabinet door compression reseting spring, thus make to produce gap between cabinet door and cabinet, thus the air pressure in cabinet is leaked.By the air pressure that leaks, effectively avoided the blast that excessively causes because of gas expansion in cabinet, thereby made whole switch cubicle fail safe higher.
Further, described pressure cap, connecting rod and locking plate are metal structure, and pressure cap and connecting rod one-body molded; Make overall structure stability better.
Further, in the outer rim of described pressure cap, be also provided with tooth bar; During convenient operation, pressure cap is rotated.
Compared with prior art, the utility model has the advantage of: simple in structure, easy for installation; By in time the air pressure in cabinet being drained, thereby effectively prevent that switch cubicle from blasting, safe.。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cabinet door, 2-pressure cap, 3-connecting rod, 4-locking plate, 5-bolt, 6-back-moving spring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, a kind of drawer of switch cabinet door blast resistance construction, comprises cabinet door 1, also comprises a circular pressure cap 2 and the connecting rod 3 being connected with pressure cap 2; During concrete enforcement, in the outer rim of described pressure cap 2, be also provided with tooth bar; So that operation time is rotated pressure cap 2.One end of described connecting rod 3 is fixedly connected with pressure cap 2, and the other end runs through cabinet door 1 from the outside of cabinet door 1 and stretches in cabinet; One end of stretching into cabinet at connecting rod 3 is provided with a locking plate 4; During installation, only need on cabinet door 1, offer a through hole passing for connecting rod 3, easy for installation.One end of described locking plate 4 is fixedly connected with connecting rod 3 by bolt 5, the other end first bends to the direction that deviates from connecting rod 3 to the direction bending that deviates from pressure cap 2 again, make whole locking plate 4 be " Z " shape, this locking plate 4 can be along the axial motion of connecting rod 3 and with pressure cap 2 rotations under the drive of pressure cap 2.Between pressure cap 2 and cabinet door 1, be also provided with a back-moving spring 6, described back-moving spring 6 sheathed with connecting rod 3 on.
Described pressure cap 2, connecting rod 3 and locking plate 4 are metal structure, and pressure cap 2 is one-body molded with connecting rod 3; Make overall structure stability better.
The utility model can be locked cabinet door and cabinet by locking plate and coordinating of doorframe, and locking plate is " Z " shape, and locking plate directly coordinates with inside doorframe; During installation, without offer locking plate hole on doorframe, make easier for installation, quick; Under the effect of back-moving spring, locking plate and cabinet door fit tightly all the time, and locking effect is good.In the time of need to opening cabinet door, press pressure cap, locking plate and doorframe are departed from, and then rotate pressure cap, when part that locking plate does not overlap with cabinet door, just can easily cabinet door be opened.While causing air to expand when cabinet internal cause generation electric arc, in cabinet, air is exerted pressure to cabinet door, force cabinet door outwards to move, owing to thering is back-moving spring between cabinet door and pressure cap, now, cabinet door compression reseting spring, thus make to produce gap between cabinet door and cabinet, thus the air pressure in cabinet is leaked.By the air pressure that leaks, effectively avoided the blast that excessively causes because of gas expansion in cabinet, thereby made whole switch cubicle fail safe higher.
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.
