Abstract
The utility model relates to a novel switch cabinet rear door interlocking mechanism which comprises a spindle, an internal part, an outer part, an unlocking part and a spring; the cross section of the outer part is a rectangular shape with an opening; one side edge of the rectangular shape is provided with an inner boss with a hole, and the corresponding other side is provided with a connecting hole; the cross section of the inner part is in a reverse T shape, both ends of the inner part are connecting ends, wherein one connecting end is a hollow spring connecting end; one end of the spindle is also a hollow spring connecting end; and the spring is connected between the inner part and the spindle. According to the novel switch cabinet rear door interlocking mechanism, the structure is simple, the operation is convenient, and the safety of a switch cabinet can be greatly improved.
Description
Technical field
The utility model relates to a kind of interlock, is specifically related to a kind of back door interlock of switch cubicle, belongs to the technical field of switch cubicle accessory.
Background technology
Switch cubicle is a kind of equipment for power transmission and distribution, and therefore, its security requirement is higher.In order to guarantee operating personnel's personal safety, when the switch cubicle "on" position, the back door is through interlock locking.The back door interlock is one of crucial in the complete switch equipment " five is anti-chain " device, is used to prevent mistakenly entering charged chamber.Do not have reliable linkage structure just can't protect personnel's safety, thus the quality of its quality, mechanical performance, structure rationally, be directly connected to the fail safe of complete switch equipment operation.
At present, the back door interlock in the complete switch equipment, main adopt have that chain, simple and easy rotary back door, electromagnetism locking-type back door is chain, chain these three kinds of 90 ° of rotation reversible back doors.The electromagnetic lock mode belongs to the on-mechanical linkage mode, and is unreliable; External environmental factor is bigger to its influence, and the high-intensity magnetic field of controller switching equipment disturbs electromagnetic lock easily, can cause misoperation; Under the improper dead electricity situation of secondary power supply, chain being failure to actuate can be caused operation or maintenance difficult, and be chain unreliable.Adopt simple and easy rotary back door linkage structure, can't realize that reversible is chain; Promptly shutting the back door, when main switch is shifted the service position onto, can realize that the back door is lockable, but, having huge potential safety hazard when opening the back door, when getting into service mode, can't realizing preventing to drive into and operating the chain function of main switch, chain unreliable.90 ° of rotation reversible back doors are chain, simple in structure, move reversiblely, but have defectives such as cabinet distortion, the dislocation of main shaft lock dog, cause chain inefficacy, and adverse consequencess such as mechanism's clamping stagnation finally cause chain failure, and poor stability jeopardizes personnel's life.Therefore, unreasonable, irreversible, invalid back door interlock can reduce the reliability and the fail safe of switchgear, threatens personal safety.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of mechanism simple, easy to operate, can improving the novel switched cabinet back door interlocking gear of switch cubicle fail safe greatly.
Technical scheme: in order to solve the problems of the technologies described above, the described novel switched cabinet of the utility model back door interlocking gear, it comprises main shaft, in-house, mechanism's exterior part, unlock piece and spring; The cross section of said mechanism exterior part is the rectangle of opening, is provided with the perforate inner convex platform at this rectangle one side, and another corresponding side is provided with connecting hole; Said in-house cross section is an inverted T-shaped, and two ends are link, and wherein a link is interior empty spring link; Said main shaft one end also is interior empty spring link; Said spring is connected between said in-house and the main shaft.
Said mechanism exterior part is made up of the 5mm cold-rolled steel.
Form by round steel with main shaft for said in-house.
Said unlock piece inserts said in-house through said mechanism exterior part.
Said in-house one end inserts said in-house, and the other end inserts said main shaft.
The utility model utilizes a kind of new back door interlocking gear, enforceable the back door is shut, and replaces original not closing the door just can send the serious leak of electricity; Solved the problem that electricity still can be sent in the back door of opening, new " five is anti-" linkage technology has improved fail safe greatly, in the use of electric cabinet; Perfect safety work has further solved root problem, and it is safer that product is used; Reliably, more humane.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: this is in-house rationally attractive in appearance, volume is revised on former basis; Easy to operate, safe in utilization, easy to maintenance; Most critical be to have guaranteed personal safety greatly; The safety of property has improved coefficient of safety, makes our product hommization more.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the described novel switched cabinet of the utility model back door interlocking gear, it comprises main shaft 1, in-house 2, mechanism's exterior part 3, unlock piece 4 and spring 5; The cross section of said mechanism exterior part 3 is rectangles of opening, is provided with perforate inner convex platform 6 at this rectangle one side, and another corresponding side is provided with connecting hole 7; Said in-house 2 cross section is an inverted T-shaped, and two ends are link 8, and wherein a link 8 is interior empty spring link; Said main shaft 1 one ends also are interior empty spring links; Said spring 5 is connected between said in-house 2 and the main shaft 1; Said mechanism exterior part 3 is made up of the 5mm cold-rolled steel; Form by round steel with main shaft 1 for said in-house 2; Said unlock piece 4 inserts said in-house 2 through said mechanism exterior part 3; Said in-house 2 one end inserts said mechanism exterior part 3, and the other end inserts said main shaft 1.The utility model reasonable in internal structure is attractive in appearance, and volume is revised on former basis, and is easy to operate, safe in utilization, easy to maintenance, most critical be to have guaranteed personal safety greatly, the safety of property has improved coefficient of safety, makes our product hommization more.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
