Abstract
A rain-proof type brake pull-rod which can be assembled rapidly comprises a rain shield out of silicon rubber arranged on the outer surfaces of insulating rods and a brake pull-head arranged at the upper ends of the insulating rods, wherein, according to the demand for effective length, a connected structure comprising a screw-on nut, a connection-peg, a screw and a fixed pin is arranged between the insulating rods, and the connection-peg and the fixed pin, after being in inserted connection with each other, are in screwed connection with the screw by using the screw-on nut; and insulating rubber is arranged on the outer surface of the brake pull-rod as a skin. The utility model is characterized in that the connection-peg adopts a U-shaped structure, the fixed pin in the screw is in inserted connection with the U-shaped connection-peg, and the rain shield adopts a double-umbrella structure. The insulating rubber-made skin of a certain thickness is additionally arranged on the outer surface of the brake pull-rod, so that collision occurs without producing sparks when a brake is pulled, and the safety is enhanced. The utility model has the advantages that connection is rapid, and the connecting point has a low possibility of being twisted off.
Description
Technical field
The utility model relates to a kind of brake pull-rod, particularly a kind of rain proof type fast-assembling brake pull-rod.
Background technology
At present, when constructing, high-tension line need cut off when maybe needing electric on the disconnected power down road on the transformer, need with a kind of direct instrument of operating a switch that contacts with high-tension electricity, the quality of the anti-electrical property of this instrument of operating a switch, directly have influence on operating personnel's life security, the known instrument of operating a switch, Chinese utility model patent as 200720148627.7, set forth and utilized a plurality of head operations of operating a switch of operating a switch, middle part at brake pull-rod also is provided with rain cover, the operation of operating a switch that head has solved various lock bodies though replacing is operated a switch, the described head of operating a switch does not have insulation function, when the conductive head body of the head of operating a switch directly contacts with high-tension electricity, be easy to generate spark, bring unsafe factor to the workmen, also there is deficiency in the known in addition instrument of operating a switch in configuration aspects, needs further to improve.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of rain proof type fast-assembling brake pull-rod.
The technical solution of the utility model is as follows:
A kind of rain proof type fast-assembling brake pull-rod is included in the insulating bar outer surface and is provided with the rain cover of making of silastic material, is provided with the head of operating a switch in the upper end of insulating bar.According to need with length between insulating bar and insulating bar, be provided with by twisting connect mother, connection-peg, twist silk, syndeton that steady pin is formed.Connection-peg and steady pin peg graft the back with twist connect female with twist stubborn closing and be connected; Operate a switch the head outer surface be provided with the elastomeric material skin that can insulate.Described connection-peg is the U font; The steady pin of twisting in the silk is connected with the connection-peg that is the U font is slotting.Described rain cover is two beveled structures.
The utility model is provided with certain thickness electro-insulating rubber material skin because of adding on the outer surface of head of operating a switch, the spark of collision produces when having avoided operating a switch, and has improved fail safe, and the utility model has and connects rapidly, and the junction such as is not easy to twist into two parts at advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure .1 insulating bar, 2 rain covers, 3 operate a switch head, 4 twist meet mother, 5 connection-pegs, 6 are twisted silk, 7 steady pins.
Embodiment
As shown in Figure 1, the outer surface on insulating bar 1 top is provided with the rain cover of making of silastic material 2, be provided with in the upper end of insulating bar 1 and operate a switch 3, according to need with length between insulating bar 1 and insulating bar 1, be provided with by twisting connect female 4, connection-peg 5, twist silk 6, syndeton that steady pin 7 is formed.Connection-peg 5 and steady pin 7 peg graft the back with twist connect female 4 with twist 6 stubborn closing and be connected.The connection-peg 5 of described syndeton is the U font, twists steady pin 7 and 5 slotting connections of connection-peg that are the U font in the silk 6.3 the outer surface of operating a switch is provided with the elastomeric material skin that can insulate, and described elastomeric material skin has certain thickness.Described rain cover 2 is two beveled structures.
