The 1/2 grading ring one-piece type capel bowl head comprises a bowl head, a capel and a grading ring socket, wherein the bowl head is connected with an insulator and provided with an opening slot connecting with the insulator, the capel is connected with a tension ring, and the grading ring socket is arranged at a connection portion of the bowl head and the capel, the grading ring socket is internally provided with jacks penetrating the whole grading ring socket, the jacks comprise a grading ring locking jack and a grading ring exit jack and are with convex shaped distribution, and width of a cross section of the grading ring locking jack is smaller than that of the grading ring exit jack. According to the 1/2 grading ring one-piece type capel bowl head, a plug on a separated type grading ring is inserted into the grading ring exit jack of the jacks, then the plug is moved to the grading ring locking jack, finally a spring pin is inserted into the grading ring exit jack. When the grading ring needs change, the spring pin is pulled out, and the plug is moved to the grading ring exit jack and pulled out. The 1/2 grading ring one-piece type capel bowl head has advantages of mounting convenience of the grading ring.

Description

1/2 grading ring connection type heart bowl head

Technical field

The utility model relates to employed strain insulator draw ring in the transmission line, particularly 1/2 grading ring connection type heart bowl head of band grading ring socket.

Background technology

General grading ring is a closed ring body, is installing, when changing, need line passed annular distance and install.In some occasions that need install additional or change, so just need be with line disconnection, install grading ring after; Circuit is being connected, and workload is very big, also needs other auxiliary gold utensils; Installation and maintenance portion is convenient; Cost increases, and grading ring all needs integral body is changed if fraction has bad phenomenon such as some are aging to produce slightly.At present also having some split type grading rings to solve the existing problem of integral type grading ring on the market, but no matter be integral type grading ring or split type grading ring, all is to adopt bolt to install, and has corona phenomenon, gives power supply safety accident potential.

The utility model content

The utility model technical problem to be solved is existing problem to be installed and a kind of 1/2 grading ring connection type heart bowl head with the grading ring socket is provided to existing integral type grading ring and split type grading ring; When its 1/2 grading ring is installed; 1/2 grading ring directly is inserted on the socket of 1/2 grading ring connection type heart bowl head and gets final product, have the advantage of easy installation and removal.

The utility model technical problem to be solved can realize through following technical scheme:

1/2 grading ring connection type heart bowl head comprises:

The one bowl head that connects with insulator, said bowl head is provided with the open slot that is connected with insulator;

One capel that is connected with the strain insulator ring;

Be arranged on the grading ring socket of said bowl head and capel junction; Be provided with the socket aperture of the whole grading ring socket of a perforation in the said grading ring socket; Be divided in the said socket aperture and be grading ring lock hole and the grading ring that convex shape arranges and withdraw from the hole, the cross-sectional width of grading ring lock hole withdraws from the cross-sectional width in hole less than grading ring.

The utility model is after connecting with insulator, and the grading ring that the plug on 1/2 grading ring is inserted in the socket aperture withdraws from the hole, then plug is moved in the grading ring lock hole, again night bolt is inserted into grading ring and withdraws from the hole and get final product.When need changing grading ring, extract night bolt, plug is moved into fall back on grading ring and withdraw from Kong Zhongzai and extract and get final product.The utlity model has the grading ring convenient installation.The utility model need not use bolt when grading ring is installed, do not have corona phenomenon, can not cause power supply safety accident potential.

Embodiment

In order to be technological means, the creation characteristic realized of the utility model, to reach purpose and be easy to understand understanding,, further set forth the utility model below in conjunction with concrete diagram with effect.

Referring to Fig. 1 to Fig. 5, the 1/2 grading ring connection type heart bowl head that provides among the figure comprises a bowl 10 that connects with insulator, and bowl 10 is provided with 11, one capels 20 that are connected with the strain insulator ring of open slot that are connected with insulator; Bowl 10 can the one die cast with capel 20.Be provided with a grading ring socket 30 in bowl 10 and capel 20 junctions; Be provided with the socket aperture of the whole grading ring socket 30 of a perforation in the grading ring socket 30; Be divided in the socket aperture and be the grading ring lock hole 31 that convex shape arranges and withdraw from hole 32 with grading ring, the cross-sectional width of grading ring lock hole 31 withdraws from the cross-sectional width in hole 32 less than grading ring.

The bowl 10 of this 1/2 grading ring connection type heart bowl head is after connecting with insulator; The grading ring that plug on the split type grading ring is inserted in the socket aperture withdraws from the hole 32; Then plug is moved in the grading ring lock hole 31, again night bolt is inserted into grading ring and withdraws from hole 32 interior getting final product.When need changing grading ring, extract night bolt, plug is moved into fall back on grading ring and withdraw to extract again in the hole 32 and get final product.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.

Claims (1)

1.1/2 grading ring connection type heart bowl head is characterized in that, comprising:
