Abstract
The utility model discloses a pressing plate protective cover. The protective cover comprises a flashboard; a blocking groove is arranged in the middle of one end of the flashboard and is a double-layer blocking groove corresponding to a base of the pressing plate and a rotating shaft; two sides of the blocking groove are provided with fixed holes; and the front face of the flashboard is provided with a sign board used for warning. The utility model can carry out safety isolation protection on an outlet pressing plate and an accessing pressing plate of and inter-tripping operation interval return circuit in a relay protection cabinet of power sectors, prevents touching by mistake or generating fault signals, and eliminates many defects of traditional rubberized fabric pasting, such as easily dropping, inconvenient dismounting, unfavorable electric conduction after dismounting, and the like.
Description
Technical field
The utility model relates to a kind of protector, particularly a kind of pressing plate misoperation of the electric screen cabinet that continues that is used for preventing power industry and the protective cover that resets.
Background technology
The relaying protection of power industry is a job of paying special attention to all the year, and reminds people is observed the safety rule system constantly, carries out operation according to operational procedure.Power industry maintenance relaying protection operation field, during professional's operation need to the inline jumping operation of screen cabinet at interval the outlet pressing plate in loop or other open into pressing plate and do quarantine measures, to prevent the personnel's misoperation in the operation process.Pressing plate is the connecting plate that comprises a base and an activity, base is fixed on relay cashier's office in a shop, two contacts are arranged on the base, the middle part of connecting plate and the middle part of base link together by rotating shaft, connecting plate can rotate around base, and brace is arranged on the connecting plate, and two of brace also is provided with the contact, contact on contact when brace is rotated into parallel position with base on the connecting plate and the base overlaps and contacts circuit turn-on.When needs cut off circuit, connecting plate is rotated to an angle, make each contact separation.Because the pressing plate in the relay cabinet is a lot, might misoperation take place and cause accident.Therefore need protect, warn, isolate forbidding closed pressing plate.Power industry normally adopts the mode of insulating tape stickup to the insulation blocking measure of these pressing plates at present; such operation is very not attractive in appearance also lack of standardization; often be pasted not strongly or wrap up not tight; if contact the signal input or the output that can make the mistake with other conductor; and can influence the electric conductivity of protection core termination, pressing plate after repeatedly pasting; be unfavorable for the stable operation of equipment, be unfavorable for the site safety operation, need further to improve perfect.
The utility model content
The utility model technical issues that need to address provide a kind of outlet pressing plate of fixing reliably, being used for protecting loop, power industry relaying protection cabinet connection jumping operation interval, open the protective cover into pressing plate.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The pressing plate protective cover, it is a plate, and the middle part of an end of plate is provided with the draw-in groove of opening, and draw-in groove is base and the corresponding double-deck draw-in groove of rotating shaft with pressing plate.Middle draw-in groove is a locating groove, and is corresponding with the rotating shaft of pressing plate, and locating groove connects the thickness direction of plate; Side at the back side of plate locating groove is provided with the base draw-in groove, and the base draw-in groove is corresponding with the base of pressing plate, and the base draw-in groove does not run through the thickness direction of plate, and its degree of depth is about 2/3 of plate thickness.
Further improvement of the utility model is: the both sides at draw-in groove are provided with fixing hole.This fixing hole is corresponding with the contact after the connecting plate of pressing plate is outwarded winding.
Further improvement of the utility model is: the front of plate is provided with the Sign Board of caution usefulness.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The utility model can be jumped the operation outlet pressing plate in loop at interval to connection in the power industry relaying protection cabinet; open into pressing plate and carry out safe isolating and protecting; it is not in place to have overcome protection such as field operation process center platen; safeguard procedures fall behind; problem attractive in appearance lack of standardization. can directly it be inserted between the connecting plate and base of opening rear fender when using the utility model; these pressing plates are protected; and the staff warned; prevent to bump or produce by mistake rub-out signal; solved that original employing rubberized fabric adhere comes off easily and nonstandard many drawbacks and adopt insulating tape to paste the back to exist conduction bad; remove a series of problems such as inconvenience. the corresponding fixing hole in the contact with connecting plate that is provided with in the draw-in groove both sides; placing the contact uses; it drops in the hole contact; preventing that connecting plate from rotating arbitrarily. result of use of the present utility model is directly perceived; eye-catching; and it is simple to operate; fixing reliable; difficult drop-off; the measure standard is clean and tidy; easy mounting arrangements; Sign Board can display device state; Sign Board makes numbering can also be set; back easy to use record can orderly management.
Description of drawings
Fig. 1 is a front schematic view of the present utility model;
Fig. 2 is the left cutaway view of Fig. 1;
Fig. 3 is the utility model and schematic diagram after pressing plate is connected.
Wherein: 1. Sign Board, 2. base draw-in groove, 3. fixing hole, 4. plate, 5. locating groove, 6. pressing plate base, 7. press plate connection board, 8. rotating shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
The utility model as shown in Figure 1, 2.This pressing plate protective cover is a plate 4, and the middle part of an end of plate 4 has draw-in groove, and draw-in groove is the double-deck draw-in groove corresponding with pressing plate base 6 and rotating shaft 8, middle little draw-in groove is a locating groove 5, it is corresponding with rotating shaft 8 sizes of pressing plate, and locating groove 5 connects the thickness direction of plate, is penetrating groove; Side at the back side of plate locating groove 5 is provided with base draw-in groove 2, and the size of base draw-in groove 2 is corresponding with pressing plate base 6, and base draw-in groove 2 does not run through the thickness direction of plate, and its degree of depth is about 2/3 of plate thickness, and base draw-in groove 2 is buckled on the pressing plate base 6.Be provided with fixing hole 3 in the both sides of draw-in groove.This fixing hole 3 is corresponding with the contact after press plate connection board 7 is outwarded winding.Plate 4 is red, and the front of plate 4 is provided with the Sign Board 1 of caution usefulness, and Sign Board 1 is yellow, and it is marked with printed words such as " forbidding dropping into ", also can indicate numbering.Schematic diagram when Fig. 3 is the utility model use, after pressing plate was opened, press plate connection board 7 was in the square crossing state with pressing plate base 6, and the contact on the press plate connection board 7 is stuck in the fixing hole 3.
