Abstract
The invention relates to a limiting type rapid insertion and extraction device which consists of a convex head and a concave head, wherein a core body and a clamping slot are sequentially arranged on the convex head; a core body butting slot and a clamping spring which are matched with the core body and the clamping slot are sequentially arranged on the concave head. According to the limiting type rapid insertion and extraction device, rapid combination and separation of a plurality of sections of insulating rods are realized; due to the design of the square core body, the possibility of torsion at an interface is fundamentally avoided; the working time is shortened, and the operation safety is guaranteed.
Description
Technical field
The present invention relates to a kind of insulating pole body of rod connection set, relate in particular to a kind of limit-type fast insert-pull device, be mainly used in the connection of more piece insulating pole in electric power system production work.
Background technique
There is following problem in the insulating bar using in present stage actual production:
1. conventional more piece insulating pole combination is installed and is wasted time and energy.
2. more piece insulating bar is when operation, and joint is very easily loosening, when giving operating difficulties, has also brought potential safety hazard.
Summary of the invention
The present invention is directed to the defect existing in above-mentioned prior art, a kind of limit-type fast insert-pull device of more piece insulating pole is provided, having solved more piece insulating pole combination installation in prior art wastes time and energy, easily loosening problem.And improved the Security of operation.
Technological scheme of the present invention is as follows:
Limit-type fast insert-pull device is comprised of plush copper and recessed head, sets gradually core body and draw-in groove in plush copper; On recessed head, set gradually core body docking groove and the jump ring matching with core body and draw-in groove.
Described core body cross section is quadrilateral or Hexagon.
Described core body cross section is square.
Described draw-in groove is hyperbola.
The end face that described draw-in groove contacts with core body is higher than core body end face.
Described recessed head is provided with the flexible snap collar for release and fastening jump ring.
Described jump ring is spring-piece type jump ring.
Advantageous effect of the present invention is as follows:
1, realize quick combined, the separation of more piece insulating pole.
2, firm and reliable connection, more piece insulating pole is difficult for departing from.
3, the design of square core body, has fundamentally stopped the possibility that rotate insulating pole joint, has improved Security and the accuracy of operation.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In figure, 1, plush copper, 2, recessed head, 101, core body, 102, draw-in groove; 201, core body docking groove, 202, jump ring, 203, snap collar.
Embodiment
Embodiment
As shown in Figure 1, limit-type fast insert-pull device is comprised of plush copper 1 and recessed 2, sets gradually square core body 101 and hyperbola draw-in groove 102 in plush copper 1, and the end face that hyperbola draw-in groove contacts with square core body is higher than square core body end face; On recessed head, set gradually square core body docking groove 201 and the hyperbola spring-piece type jump ring 202 matching with square core body and hyperbola draw-in groove.Described recessed head is provided with the flexible snap collar 203 for release and fastening jump ring.
Described core body cross section is replaceable is rectangle or hexagon.
During assembling, the snap collar that only needs to stretch is drop-down, and release elastic sheet formula jump ring docks plush copper, then unclamps flexible snap collar with recessed head, push down spring-piece type jump ring, completes the combination of two joint insulating poles; The flexible snap collar of leaving behind when separated, extracts a joint, and success is separated.
The above is specific embodiments of the invention and the know-why used, and any equivalent transformation based on technical solution of the present invention basis, within all belonging to protection scope of the present invention.
