Abstract
The utility model discloses a telegraph pole protection cap, which comprises a protection cap body, a sealing cover and a fixing nail. The protection cap body is made by the compaction of the polyethylene materials and has a short column shape, a lower end of the protection cap body is a plane concave structure, a column-shaped protuberance is positioned at a central part of an upside plane of the protection cap body, a through hole is provided in a center of the protuberance, a screw thread is provided on an outer circle of the protuberance, a corresponding screw thread is also provided on a inner side of the sealing cover, which is corresponding to the protuberance, the sealing cover is in combined connection with the protuberance screw thread on the protection cap body, and a fixing steel nail, which is compliant with the through hole, passes through the protuberance center hole. The utility model can resist the corrosion of various acid, alkali and saline. The utility model does not deform nor brittle within the 80 degree celsius high temperature and the below zero 70 degree celsius low temperature. The utility model is also convenient to install and is reliable to use, and the low cost greatly prolongs the using life of the wooden telegraph pole, which is a telegraph pole protection device worthy of great populization.
Description
Technical field
The utility model relates to the telecom transmissioning equipment technical field, relates to a kind of electric pole hard hat specifically.
Background technology
As everyone knows, in traditional telecom transmissioning equipment, be used to lay trolley wire, the wooden pole of cable is used also very extensive, advantage is to draw materials easily, processing and manufacturing is simple, but owing to be used for outdoor, expose to the sun and rain, corrosion easily, particularly the top of rod is easier is corroded, in order to solve electric pole top corrosion-resistant problem, general all is to block at the hard hat that installation iron sheet in the top of electric pole is made, but the hard hat that its shortcoming is an iron sheet to be made also is unable to undergo the invasion and attack of various etchant gases, particularly very easily corrode, and the iron sheet hard hat is that the side is fixed, is difficult for stickfast in the acid rain area, and also can be from the nail chronic water inlet in hole, this has all influenced the application life of electric pole greatly, and wooden pole corrosion-resistant problem is one and do not allow the problem ignored, and also be needs the problem that solves always in the telecom transmissioning equipment field.
Summary of the invention
Order of the present utility model provides a kind of corrosion-resistant, high-low temperature resistant, easy for installation, safe and reliable, long service life and cheap electric pole hard hat.
In order to achieve the above object, the utility model adopts following structural principle, concrete structure is: a kind of electric pole hard hat, comprise the cap body, seal cover and staple, be characterized in, the cap body of being made by the polythene material plastic compression is the short cylindrical shape, cylindrical cap body downside is the plane recessed structures, there is a cylindrical projections at cap body upper center position, and there is a through hole at the center of projection, and the cylindrical of projection has screw thread, with the corresponding seal cover of projection inboard respective threads is arranged also, seal cover is connected with projection threaded engagement on the cap body, in the centre bore of projection, pierces into the fixedly steel nail that adapts to through hole.
Described seal cover cylindrical is pressed with many vertical anti-skidding lines, also can be shaped on anti-skidding screw thread on the described fixedly steel nail.
Using method of the present utility model is such, utilize the plane recessed structures to be enclosed within the top of electric pole the hard hat of compression molding, size that hard hat is recessed and diameter can have the standard of different size according to the electric pole of different thicknesses specification, hard hat packs into behind the electric wire top centre bore that staple is passed on the hard hat, with hammer nail is squeezed in the electric pole hard hat is fixed, if screw can be fixed with screwdriver.
Owing to adopted above constructional device, make the utility model outdoor application can anti-various acid, the burn into of alkali, salt and can be in 80 degree high temperature and indeformable not embrittlement in the subzero 70 degree low temperature, the utility model long service life of wooden pole that makes easy for installation, safe and reliable, cheap prolongs greatly, is a kind of protector that can vigorously promote the use in telecom transmissioning equipment.
Description of drawings
Fig. 1 partly cuts open schematic diagram for structure of the present utility model.
Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing.
Structure of the present utility model as can be seen from Figure 1: a kind of electric pole hard hat, by cap body 1, seal cover 2 and staple 4 are formed, the cap body of being made by the polythene material plastic compression 1 is the short cylindrical shape, cylindrical cap body 1 downside is the plane recessed structures, forming external diameter is 146 millimeters, internal diameter is 140 millimeters, thick is 30 millimeters oblate staving with cover, at the planar central position of cap body 1 upside a cylindrical projections 3 is arranged, projection 3 is high 12 millimeters, 10 millimeters of external diameters and uniform screw thread, there is one 3.6 millimeters through hole at the center of projection 3, be 16 millimeters and many vertical anti-skidding lines 5 are arranged with corresponding seal cover 2 its external diameters of projection, the internal diameter of seal cover 2 is 10 millimeters and has and the corresponding internal thread of projection 3 screw threads, in the centre bore of projection 3, pierce into the fixedly steel nail 4 that adapts to through hole, hammer into fixed protection cap behind the electric pole termination, is connected with projection 3 threaded engagement on the cap body 1 with seal cover 2 again, seals and follow closely the hole.
Present embodiment only is the example explanation with the wooden pole, and the utility model also can be used for the electric pole that other materials is made.
Claims (3)
