Abstract
The utility model relates to a rotary knob type protection pressing plate comprising a pedestal (1), connecting piles (2) and a rotary knob pressing plate (3). The two ends of the pedestal (1) are respectively connected with two connecting piles (2). Two connecting sheets (4) are extended from the two connecting piles (2) to the middle part of the pedestal (1) respectively. The two connecting sheets (4) are vertically separated from each other, a gap is arranged between the two connecting sheets (4), and the tip ends of the two connecting sheets (4) are provided with screw holes which are concentric. The pedestal (1) is provided with an insulating shell which wraps the two connecting sheets (4) and a connection part of the two connecting sheets (4) and external wires. The rotary knob pressing plate (3) is mainly composed of an insulating rotary knob handle and a conductive screw rod which matches the concentric screw holes in the two connecting sheets (4). Operation of working staffs is ensured to be safer by the rotary knob type protection pressing plate; the internal structure can be designed to be more compact so that screen cabinet space is saved; false actions on switch are prevented; operation is simple and rapid; and when the rotary knob type protection pressing plate is not used for a long period, the rotary knob pressing plate can be removed completely.
Description
Technical field
The utility model relates to the transforming plant protecting device, is specifically related to a kind of knob protection pressing plate.
Background technology
The protection pressing plate is also named protection in flakes, is bridge and the tie of protective device contact external wiring, and can the function and the action outlet that be related to protection normally play a role.Because the current protection pressing plate brace generally used is exposed, throw staff while moving back operation and be easy to touch the metal part and get an electric shock; And throw when the derotation turns operation and easily touch adjacent pressing plate, cause the protection misoperation; Be fixedly connected with that the sheet knob-operated time is long, efficiency is low.It is current that to also have a kind of protection platen design be by connecting axle, to be fixed on bearing in the middle of the pressing plate brace; pass through rotatable handle; the brace plug is plugged in the pressing plate metal consent; realized that the throwing of pressing plate moves back operation; although this mode has solved mistake and has touched the problem of adjacent pressing plates and the danger that easily mistake is touched; but stipulate that long-term no protection pressing plate should take off pressing plate in flakes, this pressing plate but can't be realized.
The utility model content
The purpose of this utility model is to provide a kind of knob protection pressing plate, has solved existing protection pressing plate easy contact, misoperation and can't when not using for a long time, take off easily pressing plate problem in flakes when operation.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of knob protection pressing plate, comprise base, wiring pile and knob pressing plate, described base two ends connect respectively two wiring piles, extend two braces to the base middle part respectively from two wiring piles, described two braces have space in the middle of vertically being separated from each other and most advanced and sophisticatedly have a concentric screw, described base has insulation crust to wrap the junction of described two braces and two braces and external cable, described knob pressing plate mainly is comprised of insulated rotary handle and conductive lever, on described conductive lever and described two braces, concentric screw is complementary.
Further technical scheme is, described base is provided with two potential test holes, and respectively with two braces in described two potential test holes are connected with the junction of external cable.
Compared with prior art, the beneficial effects of the utility model are: can not touch the charged position of metal, guarantee staff's operation safe; Internal structure can design compacter, saves screen cabinet space; Can not encounter adjacent pressing plate by mistake, prevent the malfunction switch; Simple and quick, insert and can, save the operating time, increase work efficiency; When the utility model does not drop into for a long time, the knob pressing plate can be taken off, guarantee to disconnect completely.
The accompanying drawing explanation
Structural representation when Fig. 1 is the separation of the utility model knob protection pressing plate.
Structural representation when Fig. 2 is the connection of the utility model knob protection pressing plate.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 and Fig. 2 show an embodiment of the utility model knob protection pressing plate: a kind of knob protection pressing plate, comprise base 1, wiring pile 2 and knob pressing plate 3, described base 1 two ends connect respectively two wiring piles 2, extend two braces 4 to base 1 middle part respectively from two wiring piles 2, described two braces 4 have space in the middle of vertically being separated from each other and most advanced and sophisticatedly have a concentric screw, described base 1 has insulation crust to wrap the junction of described two braces 4 and two braces 4 and external cable, described knob pressing plate 3 mainly is comprised of insulated rotary handle and conductive lever, on described conductive lever and described two braces 4, concentric screw is complementary.
Further technical scheme is, described base 1 is provided with two potential test holes 5, and 5 respectively with two, described two potential test holes brace 4 is connected with the junction of external cable.
Workflow of the present utility model is:
Before this knob protection pressing plate comes into operation, can insert two each potential test holes 5 on knob protection pressing plate base 1 with the universal instrument pin, whether test potential is correct;
After confirming that test potential is correct, operating personnel insert concentric screw on two braces 4 by the conductive lever of knob pressing plate 3, and, by insulated rotary handle rotation location, complete to connect and come into operation;
When needs exit or take off knob pressing plate 3, operating personnel take out base 1 by the insulated rotary handle by the conductive lever of knob pressing plate 3 and get final product.
Claims (2)
1. a knob is protected pressing plate, it is characterized in that: comprise base (1), wiring pile (2) and knob pressing plate (3), described base (1) two ends connect respectively two wiring piles (2), extend two braces (4) to base (1) middle part respectively from two wiring piles (2), described two braces (4) have space in the middle of vertically being separated from each other and most advanced and sophisticatedly have a concentric screw, described base (1) has insulation crust to wrap the junction of described two braces (4) and two braces (4) and external cable, described knob pressing plate (3) mainly is comprised of insulated rotary handle and conductive lever, the upper concentric screw of described conductive lever and described two braces (4) is complementary.
