Abstract
Provided is a locking and positioning structure for the drawer typed switchgear power module panel. The utility model comprises a lug, a lock shaft, lock hole, a push block, a panel, a cross beam, a pressing tablet, a reset spring and an open spring expansion ring. The push block comprises a handle, a slide plate and a fork-lever. Passing through the pressing tablet, the fork lever is in stuck connection on the lock shaft. The pressing tablet and the fork-lever are in slide cooperation with each other. A slot is arranged on the lock shaft. The open spring expansion ring is arranged in the slot. The reset spring is arranged on the lock shaft between the open spring expansion ring and the upper lug. The lower face of the open spring expansion ring attaches closely to the upper face of the fork-lever. Through the push block sliding up and down, the lock shaft is driven to move up and down so as to be inserted into or plugged out of the positioning hole thus reaching the purpose of locking tightly and positioning the power module. Meanwhile, the utility model effectively achieves the purpose that a plurality of contactor plugs on the power module must contact step by step and with moving intervals with the corresponding sockets on the switchgear. The utility model with the advantages of a low manufacture cost, reliable and convenient operation effectively improves the locking and positioning method of the power module.

At present, the general drawer-type switch cabinet power module panel locking-positioning structure of Shi Yonging, complex structure, the manufacturing cost height, though a kind of comparatively simple positioning and locking structure is arranged, its lockhole is in a zigzag, when operator's one handgrip power module is advanced to certain position, another hand is laterally stirred handle, lock shaft is slided, simultaneously along lockhole, the different contactor plug substeps in module rear portion, free interval, the respective socket on the switch cubicle is fixed in insertion, locate at last, its major defect is: two hand power thrusts are inconsistent and the human physiological structure is inharmonious, in addition, in the inner sparking of power module in emergency circumstances, can not extract power module out quickly, delay the valuable processing time at sparking initial stage easily.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, low cost of manufacture, and especially in when operation, the drawer-type switch cabinet power module panel locking-positioning structure that power thrusts and human physiological structure relatively coordinate;
The utility model is achieved in that a kind of drawer-type switch cabinet power module panel locking-positioning structure, comprise journal stirrup, lock shaft, lockhole, shifting block, panel, crossbeam, perforate is arranged on the journal stirrup, lock shaft is the lock shaft of a band positioning end, positioning end radially outward slightly enlarges, lockhole is arranged on the switch cabinet panel crossbeam under the power module, be positioned at the below of lock shaft, shifting block comprises handle, slide plate, shift fork, shifting block handle extending panel outer surface, the lock shaft positioning end is vertically mounted on two journal stirrups of module up, the front end of shift fork is semicircular opening, the lock shaft diameter is suitable with the shift fork A/F, shift fork snaps in lock shaft, snap in a little between last down journal, on the lock shaft pin between the last down journal, have circumferential slot, lock shaft between circumferential slot and the upper journal is equipped with back-moving spring, construction opening spring piston ring in the circumferential slot, split ring piston ring lower plane is close on the plane on the shift fork, described location structure also comprises compressing tablet, the cross opening is arranged on the compressing tablet, the shifting block that slides up and down is between compressing tablet and panel, shift fork passes compressing tablet and snaps in lock shaft, there is symmetrical breach shift fork and slide plate junction, the vertical openings partial width of the shift fork width of this indentation, there and compressing tablet cross opening is corresponding, the thickness response of gap width and compressing tablet, shift fork can slide up and down along the dual-side of compressing tablet opening, and the length of the transverse opening part of shift fork width and compressing tablet cross opening is corresponding, so that shift fork passes compressing tablet.
Can also open positioning port in the crossbeam outside, the opening semicircular in shape, the line of centres of this opening and location hole is parallel with power supply push-and-pull direction.The interval displacement that the distance of the line of centres contacts with the substep of power contactor is corresponding.
Can have a plurality of circumferential slots on the lock shaft, the split ring piston ring is installed in the elastic force that different circumferential slots just can be regulated split ring, to adapt to operation.
Adopt said structure not only simple in structure, make and assemble easily, cost is low; And when push-and-pull, two hands are firmly coordinated, and when advancing power supply near the location, upwards stir shifting block with hand, advance power supply again, and lock shaft springs into location hole automatically; When pulling out power supply, upwards stir shifting block, can make things convenient for and pull out power supply fast with hand.
