Preferably, the top of lag is provided with the joint portion with the main part looks joint.

Preferably, a first protrusion is arranged above the outer wall of the inner sleeve, and a first groove corresponding to the first protrusion is arranged below the inner wall of the protective sleeve.

Preferably, the outer wall of the connecting piece is provided with a second protrusion, and a second groove corresponding to the second protrusion is arranged above the inner wall of the inner sleeve.

Preferably, a hollow ring is fit above the inner wall of the protective sleeve, and a through hole is formed in the top of the hollow ring.

Compared with the prior art, the beneficial effects of the utility model are that: this ageing resistance column insulator through the cooperation between endotheca, lag and the compression cover, cooperates external fixed knot to construct and main part, forms confined space, plays the effect of protection to the connecting piece, avoids adhering to of rainwater and dust, plays the effect of ageing resistance, improves life, and the relative ratio has longer life cycle in directly exposing outside.

Through the inside of hollow ring setting at the lag, can be to a small amount of steam that gets into and contact the connecting piece, quick quilt is absorbed, has further improved the effect of ageing resistance, and this ageing resistance column insulator global design simple structure easily produces and assembles, has stronger practicality.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an ageing resistance column insulator, includes main part 1, and connecting piece 2 is installed to main part 1, and lag 3 has been cup jointed to the outer wall below of main part 1, and the inner wall clearance fit of lag 3 has cup jointed the endotheca 4 in connecting piece 2 outer wall, and the bottom of endotheca 4 is provided with compression cover 5, and the top of endotheca 4 is provided with the cuff 6 that corresponds lag 3.

It should be noted that the main body 1 is an insulating portion of an insulator and other corresponding components, and the structure of the main body is not improved in this application, and therefore, the detailed description thereof is omitted.

It can be understood that lag 3, endotheca 4 and the cooperation of compression cover 5 three, under the cooperation of main part 1 and the 2 bottom connection structure of connecting piece, with connecting piece 2 parcel wherein, play the effect of protection, avoid oxidation etc. wherein the design of cover mouth 6, realize after endotheca 4 stimulates downwards, endotheca 4 can be inseparable laminating together with lag 3, compression cover 5 can be through self deformation, and then support tightly with the structure that connecting piece 2 is connected, realize the sealing of this department.

Further, the top of lag 3 is provided with the joint portion 7 with main part 1 looks joint.

It should be noted that the design of the clamping portion 7 can fix the protective cover 3 and the main body 1, and improve the sealing performance therebetween.

Further, a first protrusion 8 is arranged above the outer wall of the inner sleeve 4, and a first groove 9 corresponding to the first protrusion 8 is arranged below the inner wall of the protection sleeve 3.
