Abstract
The utility model relates to a limiting and blocking device of an instrument door of a power distribution cabinet. The limiting and blocking device of the instrument door of the power distribution cabinet is composed of a base seat A, a base seat B, a pull rod, a pin, a sliding groove and a limit hole. The base seat A is fixed on an instrument door, the base seat B is fixed on the side plate of a cabinet body, the sliding groove is formed in the base seat A, one end of the pull rod is movably connected on the base seat B, the other end of the pull rod is connected in the sliding groove of the base seat A in a sliding and clamping mode, and a limit groove is formed in one end, close to a door shaft, of the sliding groove. When an instrument is installed and maintained, the open state of the instrument door can be limited and blocked to maintain the open state, and the instrument door is prevented from automatically closing to affect a manual operation due to stress. When the instrument door is closed, a user simply needs to push the pull rod or the pin, the instrument door is closed, and the limiting and blocking device of the instrument door of the power distribution cabinet is simple in operation, safe and reliable.
Description
Technical field
The utility model relates to a kind of power distribution cabinet instrument door limited position stoppage device, particularly power distribution cabinet instrument door fastening device.
Background technology
The instrument door of power distribution cabinet in the electric power a complete set of equipment industry is owing to will install more double measurement, control instrument, and the secondary line that instrument need to connect is more, bundle of conics needs colligation to fix at mistake instrument door place, bundle of conics can produce at the place of moving into one's husband's household upon marriage larger stress, and the traditional design scheme of power distribution cabinet does not have the stopping means of instrument door, so at door lock not during locking state, the position of instrument door can not be fixed at instrument door.
After instrument door is opened, when the Operation and Maintenance personnel to the secondary wiring terminals inlet wire in control room operation or when safeguarding, the instrument door position can arbitrarily be rocked, and affects staff's operation.
The utility model content
For addressing the above problem, the utility model provides a kind of power distribution cabinet instrument door limited position stoppage device, not during locking state, can carry out limited position stoppage at the power distribution cabinet instrument door lock to the instrument door position, not affect operating personnel to the operation of the secondary wiring terminals inlet wire in the control room or safeguard.
The utility model is achieved in that a kind of power distribution cabinet instrument door limited position stoppage device, is comprised of base A, base B, pull bar, pin, chute, spacing hole; Base A is fixed on the instrument door, and base B is fixed on the side cabinet, has chute on the base A, and one of pull bar is movably connected on the base B, slides by pin and be connected in the chute of base A in the other end, and chute is provided with stopper slot near an end of door-hinge;
Described stopper slot be a diameter greater than the circular port of chute width, be communicated as one with chute;
Described pin is to be made of nut and screw, and the diameter of nut is greater than the diameter of stopper slot; A limited location snap ring is arranged between nut and screw, and the diameter of limited location snap ring is greater than the width of chute, and less than the diameter of stopper slot;
Being shaped as of described limited location snap ring is round table-like, and the diameter of close nut one end is greater than the diameter of the other end.
The beneficial effects of the utility model: install, when safeguarding instrument, the instrument door door opening state can limited position stoppage, keeps opening-wide state, prevents that instrument door is owing to stress reason Automatic-closing affects personnel operation; When closing instrument door, only need top one lower link or special pin, just can close instrument door, simple to operate, safe and reliable.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model base A;
Fig. 3 is the structural representation of the utility model pin.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, 2: a kind of power distribution cabinet instrument door limited position stoppage device is comprised of base A 1, base B 5, pull bar 4, pin 3, chute 2, spacing hole; Base A 1 is fixed on the instrument door, base B 5 is fixed on the side cabinet, has chute 2 on the base A 1, and one of pull bar 4 is movably connected on the base B 5, slide by pin 3 and be connected in the chute 2 of base A 1 in the other end, chute 2 is provided with stopper slot 6 near an end of door-hinge; Stopper slot 6 is that a diameter is communicated as one greater than the circular port of chute 2 width and with chute; Pin 3 is to be made of nut 7 and screw 9, and the diameter of nut 7 is greater than the diameter of stopper slot 6; A limited location snap ring 8 is arranged between nut 7 and screw 9, and the diameter of limited location snap ring 8 is greater than the width of chute 2 diameter less than stopper slot 6.
Principle is as follows: when instrument door is closed the door state, pin 3 is in and is free to slide the position, when opening instrument door, pin 3 is in chute 2 interior slips, when instrument door opened to the limit, the limited location snap ring of pin 3 fell within the stopper slot 6 for 8 times and is stuck, and pin 3 is in the limited position stoppage position, realize the limitation locking function, the instrument door position is fixed; When closing instrument door, only need pulling pin 3 to make it to jump out stopper slot 6 and just can be free to slide, close simultaneously instrument door, pin 3 can realize then that in chute 2 interior slips the pass of instrument door is closed.
As shown in Figure 3: a kind of power distribution cabinet instrument door limited position stoppage device, being shaped as of described limited location snap ring 8 is round table-like, and the diameter of close nut 7 one ends is greater than the diameter of the other end.
Principle is as follows: when instrument door has opening-wide state to transfer closed condition to, only need spur pull bar 4, owing to the round table-like design that is shaped as of the limited location snap ring 8 on the pin 3, pin 3 will be pulled to chute 2 and realize slip at this moment, and instrument door just can be shut.
The utility model describes by accompanying drawing, in the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
