Abstract

The invention discloses an explosion-proof door of a switch cabinet with promoted locking function, which solves the problems of insufficient strength, low reliability or cabinet door locking complexity, low operation efficiency and the like after the handcart room cabinet door of the conventional mobile switch cabinet is locked. A limit mounting bracket and a mounting bracket are welded on a door panel, operation locking mechanisms are assembled in the limit mounting bracket and the mounting bracket, the lateral surface of the door panel is assembled with a multifunctional hinge, and the operation locking mechanism is connected with the multifunctional hinge. Through the operation locking mechanisms, the related parts inside the hinge produce relative sliding translation to drive the dropping or rising of the door panel so as to implement locking or unlocking of the door panel and the cabinet body. The explosion-proof door has the advantages of high strength, high reliability, simple locking of cabinet door and high operation efficiency after locking.

Description

Has the switch cubicle explosion preventing gate that promotes lock function
Technical field
The present invention relates to a kind of switch cubicle explosion preventing gate that promotes lock function that has.
Background technology
Along with China opens electric power and the manufacturing develop rapidly of switchgear, armouring type withdraw-type ac metal closing switch gear is widely used, and simultaneously people are to operation, quality, the security performance of switch cubicle, proposed higher, more fully requirement.Many switch products in the market, all there is complicated operation in the cabinet door-plate with the operator directly contacts, and locking back intensity is not high, the common problem of poor reliability.
Summary of the invention
The purpose of this invention is to provide a kind of switch cubicle explosion preventing gate that promotes lock function that has, to solve existing withdraw-type switch cabinet handcart chamber cabinet door lock back undercapacity surely, reliability is low or cabinet door lock is fixed complicated, the low problem that waits of operating efficiency.
The present invention is welded with limit mounting support and mounting bracket on door-plate, be equipped with operational lock mechanism in limit mounting support and the mounting bracket, door-plate side assembling multifunctional hinge, and operational lock mechanism links to each other with multifunctional hinge.
The present invention makes to drive the reduction or the rising of door-plate by the relative sliding translation of generations between the hinge related parts inside by operational lock mechanism, the locking of realization door-plate and cabinet or unlock; By horizontal push-and-pull door-plate, make and the relative rotation of generation between the hinge related parts inside realize that the rotation pass of cabinet door-plate is closed; After the door-plate locking, fixedly connected with cabinet in four limits, upper and lower, left and right of door-plate, lock be disengaged after, fixedlying connected between four limits, upper and lower, left and right of door-plate and the cabinet automatically terminates.
The present invention locks back intensity height, and reliability height, cabinet door lock are simple surely, the operating efficiency height.

Embodiment
Following execution mode can make those skilled in the art more fully understand the present invention, but does not limit the present invention in any way.
The present invention is welded with limit mounting support 4 and mounting bracket 5 on door-plate 1, be equipped with operational lock mechanism 6 in limit mounting support 4 and the mounting bracket 5, door-plate 1 side is equipped with many group hinges 3 and one group of multifunctional hinge 7, and operational lock mechanism 6 links to each other with multifunctional hinge 7.
Operational lock mechanism 6 comprises operation axle sleeve 12, connecting lever sheet 13 and the axle 14 that is welded as a whole, axle 14 is connected with connecting plate 15, operation axle sleeve 12 is assemblied in the hole 25 of mounting blocks 10 after spacing by little axle 11, and mounting blocks 10 is fixedly connected on limit mounting support 4 and the mounting bracket 5; Operation axle sleeve 12 passes circular hole 24 on the door-plate 1, and connecting plate 15 is connected with contiguous block 18 on the multifunctional hinge 7 by connecting axle 20.Under the moment loading, operation axle sleeve 12 can rotate in the hole of mounting blocks 10 outside, and drives connecting plate 15 by default orbiting motion by connecting lever sheet 13, axle 14.
Multifunctional hinge 7 comprises fixed block 16, multifunctional hinge axle 17, cabinet fixed block 19, fixed block 16 is fixedlyed connected with door-plate 1, cabinet fixed block 19 is fixedlyed connected with cabinet, be provided with multifunctional hinge axle 17 in the hole 27 of fixed block 16, the sidewall of fixed block 16 has stopper slot 26, the end of contiguous block 18 is passed stopper slot 26 and is packed in the groove of cabinet fixed block 19, is enclosed within simultaneously on the multifunctional hinge axle 17.Contiguous block 18 can only rotate around multifunctional hinge axle 17 with fixed block 16 in the groove of cabinet fixed block 19.
Hinge 3 plays the hinge effect, and hinge 3 comprises hinge fixed block 21, hinge axis 22, little fixed block 23, and hinge fixed block 21 is fixedlyed connected with door-plate 1; Little fixed block 23 is fixedlyed connected with cabinet; Hinge fixed block 21 is connected by hinge axis 22 with little fixed block 23.
Curvature around the door-plate 1 is provided with door-plate locking edge 2, locking edge 9 and locking teeth 8 with the cabinet corresponding matching on the curvature limit.
Rotation by the operation axle sleeve 12 in the operational lock mechanism 6, make multifunctional hinge axle 17 relative sliding translation in the hole 27 of cabinet fixed block 19 of multifunctional hinge 7 inside, hinge axis 22 on the hinge 3 drives the reduction or the rising of door-plate with hinge fixed block 21 translation in the hole of little fixed block 23, realizes the locking of door-plate locking edge 2, locking edge 9 and locking teeth 8 or unlocks; By the push-and-pull door-plate, make and the relative rotation of generation between multifunctional hinge 7 and hinge 3 related parts inside realize that the rotation pass of cabinet door-plate is closed; After the door-plate locking, fixedly connected with cabinet in four limits, upper and lower, left and right of door-plate, lock be disengaged after, fixedlying connected between four limits, upper and lower, left and right of door-plate and the cabinet automatically terminates.
