Abstract
The utility model discloses an earthing switch AND gate interlocking device, including the cabinet body, cable chamber door, operating device, cam mechanism, the release link of taking locking device, earthing switch restore to the throne dog, earthing switch release link, operating device main shaft drive cam mechanism, cam mechanism connect the locking device of release link, and earthing switch restores to the throne the dog and is connected with the earthing switch release link, and the cable chamber door physically can be dismantled with the cabinet and be connected, and cable chamber door top is equipped with the U type groove with earthing switch release link adaptation. The utility model discloses do not receive space limitation, high, safe and reliable of life -span.
Description
Technical field
The utility model relates to power transmission and distribution field, especially relates to a kind of earthed switch and door interlocking mechanism.
Background technology
The raising required along with Electric Appliance Cabinet product security of operation, simultaneously switching devices miniature requirement are obvious.The target more and more higher to the requirement of " five prevent ", simple, reliable, practicality becomes design.
At present, on market in order to meet miniature requirement.The scheme generally taked has: 1, earthed switch and door interlocking mechanism adopt plastics flexible cord to add pipe to carry out transmission.2, door adopts 2 directions to be connected with cabinet.The reliability of such scheme interlocking is low, the life-span is low, door closedown intensity is low.
Utility model content
The utility model aims to provide a kind of earthed switch and door interlocking mechanism, and not by spatial limitation, the life-span is high, safe and reliable.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Earthed switch disclosed in the utility model and door interlocking mechanism, comprise cabinet, cable chamber door, operating mechanism, cam mechanism, the release link of locking device, earthed switch reset baffle block, earthed switch release link, described operating mechanism main shaft driving cam means, described cam mechanism connects the locking device of release link, described earthed switch reset baffle block is connected with earthed switch release link, described cable chamber door and cabinet removably connect, and described cable chamber door top is provided with the U-type groove with earthed switch release link adaptation.
Further, described cable chamber door both sides arrange four pivot pins, and cable chamber door coordinates with the T-slot in cabinet.
Preferably, described release link comprises back-moving spring.
Preferably, described operating mechanism, cam mechanism are arranged on cabinet inside by mounting panel.
After cable chamber door is linked into cabinet installation site, drags earthed switch reset baffle block, ground connection switching manipulation hole is unlocked.
Described operating mechanism is to ground connection switching manipulation separating brake.After switch separating brake, main axis driving cam means rotates.
Described cam mechanism transmission displacement, drives release link end of door plate to lock.Now, door locking can not carry out opening door operation.
The utility model is not by spatial limitation, and the life-span is high, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of interlocking device's part;
Fig. 3 is that cable chamber door coordinates schematic diagram with cabinet.
In figure: 1-operating mechanism, 2-ground connection handle hole, 3-earthed switch reset baffle block, 4-earthed switch release link, 5-T type groove, 6-pivot pin, 7-cam mechanism, 8-release link, 9-cable chamber door, 10-cabinet.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, Figure 2, Figure 3 shows, earthed switch disclosed in the utility model and door interlocking mechanism, comprise the release link 8 etc. of cabinet 10, cable chamber door 9, operating mechanism 1, earthed switch reset baffle block 3, earthed switch release link 4, cam mechanism 7, band locking device; Cabinet 10 is connected with cable chamber door 9, operating mechanism 1 main shaft drives cam mechanism 7, controls the locking device of release link.
Cabinet 10 is as follows with the connected mode of cable chamber door 9: cable chamber door 9 both sides arrange four pivot pins 6.When being linked into when door-plate level in the T-slot 5 in cabinet 10, earthed switch release link 4 is inserted in the U-type groove 5 on cable chamber door 9 top.
Door-closing operation, cable chamber door 9 vertical direction pushes in T-slot 5, and after pulling earthed switch release link 4 to move 18mm straight down, earthed switch reset baffle block 3 is opened, and ground connection handle hole 2 is opened, to carry out the sub-switching operation of earthed switch; Operational grounding switch separating brake, cam mechanism 7 rotates clockwise; Drive release link 8 to move downward, withstand cable chamber door 9 top edge; Cable chamber door 9 bar 8 that is reset limits the displacement moved upward.
Otherwise, opening door operation, first, carry out counterclockwise closing operation to earthed switch, cam mechanism 7 rotates counterclockwise, and release link 8 moves upward under the active force of release link 8; Cable chamber door 9 top unlocks, and cable chamber door 9 can upwards be mentioned, and earthed switch reset baffle block 3 moves upward under the effect of release link 8, and now, ground connection handle hole 2 blocks, and cable chamber door 9 can level be taken out.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the utility model.
