Description
Technical field
The present invention relates to switch cubicle locking field, especially a kind of Lock for switch cabinet locking apparatus.
Background technology
At present, switch cubicle belongs to controller switching equipment, and security is most important, in order to ensure the security of switch cubicle,Need between cabinet door and door body, blocking device be set, present blocking device complex structure, complex operation,And take a large amount of inner spaces of switch cubicle, also just taken the peace of the electric components such as breaker assembling cabinet, contactDress space, the space that has increased whole switch cubicle, meanwhile, the locking degree of blocking device is poor, easily distortion.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, provides a kind of Lock for switch cabinet locking apparatus.
For achieving the above object, the present invention adopts following technical proposals:
A kind of Lock for switch cabinet locking apparatus, comprises the locking sheet being arranged between cabinet door and secondary plug, locking sheetFor L-type structure, and the plane at locking sheet place is parallel with cabinet door, and locking sheet is arranged at secondary plug front portion,Described locking sheet one end arranges fixture, and the other end is fixedly installed pivot pin, and described fixture is fixed on cabinetBody inside top and fixture are arranged at directly over secondary plug, and described pivot pin and locking sheet place plane are hung downDirectly, and pivot pin end arranges latch shaft, and described latch shaft is scalable, arranges to mate with latch shaft on cabinetHole, described fixture is flexibly connected with locking sheet.
Preferably, described fixture comprises fixture and connecting axle, and described fixture is fixed on cabinet insideTop, and fixture comprises groove and is arranged at the fixed angles at groove two ends, connecting axle level is fixedly installed onInside grooves, and locking sheet one end is vertical with connecting axle.
Further preferred, described fixed angles arranges fixing hole, realizes consolidating of fixture by fixing fixing holeFixed.
Preferably, locking sheet is the L-type structure with certain radian, and L-type structure in angular region be [120,150]。
Preferably, latch shaft is solid cylinder structure, and the length sum of latch shaft and pivot pin is greater than secondary-plugSeat and the distance of cabinet door. By above-mentioned setting, latch shaft can freely stretch in the hole of cabinet door, realizes locking behaviourDo.
The invention has the beneficial effects as follows:
1. the blocking device the invention provides is simple in structure, processing ease, and blocking device small volume,Save a large amount of inner spaces for inside switch cabinet, reduced the space of whole switch cubicle;
2. blocking device locking degree provided by the invention is better, realizes locking do by the gravity principle of locking sheetWith, realize simply, workable, be easy to promote;
3. blocking device provided by the invention is not made larger change to switch cubicle body, only on cabinet doorHole is set, and in cabinet inside top, the hole corresponding with fixture is set, technique easily realizes.
Brief description of the drawings
Fig. 1 is Lock for switch cabinet locking apparatus front view provided by the invention;
Fig. 2 is Lock for switch cabinet locking apparatus top view provided by the invention;
Fig. 3 is Lock for switch cabinet locking apparatus left view provided by the invention;
Fig. 4 is Lock for switch cabinet locking apparatus use procedure structural representation provided by the invention;
Wherein 1. locking sheets, 2. pivot pin, 3. latch shaft, 4. connecting axle, 5. fixture, 6. secondary plug.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1 to Figure 3, a kind of Lock for switch cabinet locking apparatus, comprises and is arranged at cabinet door and secondary plug 6Between locking sheet 1, locking sheet 1 is L-type structure, and the plane at locking sheet 1 place is parallel with cabinet door,Locking sheet 1 is arranged at secondary plug 6 front portions, and described locking sheet 1 one end arranges fixture, and the other end is solidPivot pin 2 is set surely, and described fixture is fixed on cabinet inside top and fixture is arranged at secondary plug 6Directly over, described pivot pin 2 is vertical with locking sheet 1 place plane, and pivot pin 2 ends arrange latch shaft 3,Described latch shaft 3 is scalable, and the hole of mating with latch shaft 3, described fixture and locking are set on cabinetSheet 1 is flexibly connected.
Preferably, described fixture comprises fixture 5 and connecting axle 4, and described fixture 5 is fixed on cabinetBody inside top, and fixture comprises groove and is arranged at the fixed angles at groove two ends, connecting axle 4 levels are solidSurely be arranged at inside grooves, and locking sheet 1 one end is vertical with connecting axle 4.
Further preferred, described fixed angles arranges fixing hole, realizes consolidating of fixture by fixing fixing holeFixed. Because blocking device is had relatively high expectations for the sealed of door of switch cabinet, this just requires fixture to realizeGood is fixing, could realize the setting of locking sheet and Secondary socket relative position, for this reason, and in fixed anglesSome fixing holes are set, realize the effectively fixing of fixture.
Preferably, locking sheet 1 is for having the L-type structure of certain radian, and in L-type structure angular region be [120,150]. Locking sheet is that L-type structure and bearing pin are vertical with locking sheet place plane, sharp if locking sheet is set toAngle, when locking sheet is sagging according to self gravitation, sagging space is less, and for this reason, locking sheet is set to bluntAngle, is set to obtuse angle by locking sheet, and the sagging space of locking sheet is larger, and be beneficial to and realize blocking function,By being [120,150] by angular region in L-type structure, when locking, angle is easily held.
Preferably, latch shaft 3 is solid cylinder structure, and latch shaft 3 is greater than with the length sum of pivot pin 2The distance of Secondary socket 6 and cabinet door. By above-mentioned setting, latch shaft 3 can freely stretch in the hole of cabinet door,Realize lock operation.
The course of work is as follows:
When secondary plug 6 is not inserted in Secondary socket, locking sheet 1 is subject to self gravitation effect, under natureThe state of hanging down, because fixture is arranged on directly over Secondary socket, and locking sheet 1 is arranged at secondary plug 6Front portion, latch shaft 3 is stretched in the hole of cabinet door, because latch shaft 3 is arranged at pivot pin 2 ends, lockingAxle 3 is against on pivot pin 2, and due to the only effect of shelves of latch shaft 3, cabinet door cannot normally be closed;
In the time that secondary plug 6 is inserted in Secondary socket, locking sheet 1 is received the support of secondary plug 6, locking sheet1 rises, and locking sheet 1 drives on pivot pin 3 and moves, and latch shaft 3 can move freely under the passing of cabinet door,Realize normally closing of cabinet door.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned, not to the present inventionThe restriction of protection domain, one of ordinary skill in the art should be understood that on the basis of technical scheme of the present invention,Those skilled in the art do not need to pay various amendments that creative work can make or distortion still in the present inventionProtection domain in.
