Description
Technical field
The utility model relates to a kind of distribution box, and especially a kind of distribution box that can automatic door-closing, belongs to distribution box technical field.
Background technology
For external distribution box, after the work of staff in completing distribution box, must remember to shut conveniently the door of distribution box, once forget and close, cause some dunghills or toy etc. to enter distribution box, will cause the phenomenons such as the interior transformer low voltage switch trip of casing, both affect the normal use of circuit, also have certain potential safety hazards such as fire.So must design a kind of distribution box that can automatic door-closing, guarantee that staff is forgetting at closing time, also can realize the automatic door-closing of distribution box.
China Patent No. is the utility model patent of ZL201220137583.9, disclose a kind of by hinge connected between distribution box door body and distributing box, replace to automatically reset spring hinge can automatic door-closing distribution box.Although adopt the automatic door-closing that can realize in this way distribution box, also had several problems simultaneously: the first, staff is beating opening door body while carrying out work, and due to the effect of spring hinge, a door body tends to close all the time, and work is very difficult normally to be carried out; The second, when switch gate number of times is frequent, the elasticity of spring hinge also weakens relatively, now, if need to change, just must remove door body is whole, then the spring hinge more renewing, extremely expending time in and manpower, maintain and replace is very inconvenient; The 3rd, the door body of opening is when automatically closing, the elasticity that is subject to spring hinge can produce larger impact, make a body " bang " a sound just shut, in order to prevent the impact that in distribution box, electronic devices and components are closed the door, affect, staff need to be with the closing of the slow auxiliary door body of hand, and careless slightlyly also can, by hand folding, use very inconvenient.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of can automatic door-closing, position gates body automatically after opening the door, convenient maintenance and replacement, the door self-closing type distribution box of impulsive force when alleviating a body and closing.
Design: in order to realize above-mentioned purpose of design.1, between connecting rod of door body hinged inside, and connecting rod and door body, be provided with torsion spring; The connecting rod other end slides in chute by slide block, realizes the rotation of connecting rod; In chute, be provided with dead bolt.The object of design is like this: utilize dead bolt slide block can be stuck in chute, stop the slip of slide block, and then stop the rotation of connecting rod, make a body can stay open state, door body does not rotate, and staff just can work easily in distribution box like this, can not be subject to the impact of a body.2, the dead bolt of electromagnetic lock is switch with slide block and coordinates, and the power end of electromagnetic lock and the power end of distribution box are connected.The object of design is like this: staff is after finishing the work, and after the energising of distribution box power end, electromagnetic lock is also switched on, and electromagnetic lock, by rear release, makes dead bolt and slide block in opened condition, and connecting rod rotates under the effect of torsion spring, self-closing doors body.3, connecting rod top shoe slides in chute, and the rotation of drivening rod realizes automatically closing of door body.The object of design is like this: when door body is closed automatically, connecting rod is under the effect of spring, there is a power of trend rotation, and this revolving force is converted into the sliding force of slide block in chute, due to the slip of slide block in chute, decompose, cushioned revolving force, reduced impulsive force when door body is closed automatically.4, one end of connecting rod is hinged on a body inner side by torsion spring.After long-term use, if the elasticity of torsion spring weakens in the time of need to changing, only need pull down the hinged end of connecting rod and door body, can take off torsion spring and change, operation is very simple, convenient.
Technical scheme: a kind of door self-closing type distribution box, comprise distribution box, in distribution box, the inner side of door body and connecting rod one end are hinged by torsion spring; The connecting rod other end is slidably matched by slide block and the chute being fixed in the fixed block in casing; Fixed block is provided with electromagnetic lock, and the dead bolt of electromagnetic lock is switch with slide block and coordinates; The power end of electromagnetic lock is connected with the power end in distribution box.
Preferably, on electromagnetic lock, be connected with time-delay relay.
Preferably, the cross section of chute is rectangle.
Preferably, slide block is circular.
Preferably, connecting rod and door body hinged place, be positioned at by casing and door body gemel connection place one side
Preferably, electromagnetic lock comprises iron block and is fixed on the magnechuck in casing; Iron block is positioned at magnechuck below; Dead bolt is positioned at the pilot hole of fixed block, and dead bolt passes pilot hole and iron block is fixed.
Preferably, on fixed block, to iron block direction, be extended with boss; Boss middle part has pilot hole, and boss top is provided with baffle ring; Dead bolt passes baffle ring and iron block is fixed.
Preferably, dead bolt is comprised of upper end guide post and lower end fixture block; Guide post upper end passes baffle ring and iron block is fixed, and guide post lower end and fixture block are fixed.
Preferably, between fixture block and baffle ring, be provided with spring; Guide post is positioned at spring.
Preferably, the diameter of fixture block is greater than the internal diameter of baffle ring; Fixture block bottom surface is inclined-plane, and to slide block lopsidedness.
The utility model is compared with background technology, and the one, due to the effect of dead bolt, the door body after opening is located, avoided staff to be subject to a body trend power affect and hindered normal operation, saved the operating time, improved operating efficiency; The 2nd, after energising, electromagnetic lock unlock, dead bolt and slide block are opened, connecting rod is under the effect of torsion spring, band movable slider moves in chute, and then a body is closed automatically, avoid not closing a body because of staff's error, and make to enter the normal use that dunghill in distribution box or toy affect circuit; The 3rd, the setting of time-delay relay, made by rear a period of time, and just release of electromagnetic lock, closes a body, has avoided staff also not walk out distribution box, and the situation that door body is just closed automatically occurs, and is conducive to staff's operation; The 4th, when a body is closed, the slip of connecting rod inner slide in chute, has decomposed the revolving force of door body, has reduced impulsive force when door body is closed automatically, has protected the electronic devices and components in distribution box, the useful life of having improved distribution box; The 5th, a body is by gemel connection on distributing box, and torsion spring is positioned at a body inner side, when maintenance and replacing torsion spring, just does not need door body to disassemble like this, not only time saving and energy saving, also makes maintenance and changes more and simplify.
