Abstract
The utility model discloses an iron tower anti-theft cap bolt, and belongs to the technical field of bolts. The iron tower anti-theft cap bolt comprises a bolt with a big end arranged to be of a tetragonal structure and an anti-theft cap. A rotatable circular outer cover is arranged outside the anti-theft cap, a clamping nut cap is arranged inside the anti-theft cap, and the anti-theft cap is connected with a sealing nut cap. A groove is arranged in the bottom of an inner cavity of the sealing nut cap. A cambered surface is arranged at the top end on the outer portion of the sealing nut cap. According to the iron tower anti-theft cap bolt, the bolt is arranged to be of the tetragonal structure, a traditional internal hexagonal wrench can not be used for conducting operation, the difficulty of stealing tower materials is increased, and cost is saved. The anti-theft cap and the sealing nut cap are additionally arranged, a streamline appearance enables lawbreakers to do not start to steal, and the purpose of being anti-theft is effectively achieved. The iron tower anti-theft cap bolt is simple in structure, convenient, practical, high in safety performance, and prone to popularization and use.
Description
Technical field
The utility model belongs to the bolt technical field, particularly a kind of iron tower Anti-theft cap bolt.
Background technique
Electric transmission line is the important constituent element of electric power system, and it rises in electric power system and carries and exchange power
Effect.Overhead transmission line is being undertaken away from the task of transmitting electric power, connecting electrical network.Overhead transmission line is supported by the shaft tower facility, spread all over rural area, cities and towns, hills, mountains and rivers and lake, and shaft tower is connected by bolt by the tower material and be fastening, the nut of existing bolt is very easily dismantled, some lawless persons seize the opportunity theft tower material, and the loss of power accident of falling the tower is frequently taken place.In the operation maintenance of high voltage power transmission power circuit, often find that iron tower loses the phenomenon of tower material, one or two at least, more than ten at most; If lost the important force part of iron tower, as untimely discovery, probably cause the serious accident of the circuit broken string of falling the tower, brought great hidden danger for the safe operation of circuit.The iron tower group all can be installed the Anti-theft cap bolt after standing and finishing in the past, can not stop to lose the phenomenon of tower material always, reason is exactly that Anti-theft cap bolt framework does not become for many years, structure is too simple, just can easily lay down with the socket wrench of selling on the market, so present Anti-theft cap bolt has not adapted to the needs of power construction develop rapidly.Some electric power enterprise has taked screw rod silk mouth to beat anti-theft measures such as the fourth of the twelve Earthly Branches, WELD NUTS, but its poor effect, nut is laid down easily, and the tower material remains stolen; WELD NUTS, although firmly, good anti-theft effect is being with electric welding machine, generator to run all over the mountains and plains, not only the workmen is arduous, and time-consuming, inefficiency.CN 2683916 Y disclose a kind of anti-theft bolt, comprise screw rod, nut, and opening slot porose and that be communicated with this hole is set at screw rod silk mouth center; Also comprise the taper bolt expandable nail that cooperates with silk mouth center hole.When but this anti-theft bolt is installed described bolt expandable nail, cumbersome, detained loosely and be removed easily, and loosening by spanner easily, connection reliability reduces, and has potential safety hazard.
The model utility content
The utility model purpose is to solve the problem that bolt is unloaded by ordinary casing easily, and a kind of simple to operate, safe and reliable iron tower Anti-theft cap bolt is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of iron tower Anti-theft cap bolt, it comprises that big end is set to bolt and the Anti-theft cap of tetragonal, the rotatable round overcoat of described Anti-theft cap outer installment, described Anti-theft cap inside arranges the clamping block, and described Anti-theft cap connects sealing cap.
Described sealing cap intracavity bottom arranges groove.
Described sealing cap outer tip end arranges cambered surface.
The utility model comprises that big end is set to bolt and the Anti-theft cap of tetragonal, has changed traditional Hexagon bolt, and traditional inner hexagon spanner can't be operated, and has increased the difficulty of stealing the tower material, can have to play effectively antitheft purpose; The rotatable round overcoat of described Anti-theft cap outer installment, described Anti-theft cap inside arranges the clamping block, during use, described bolt is enclosed in described Anti-theft cap inside, and the stressed rotation of described rotatable round overcoat does not drive described bolt action, described Anti-theft cap connects sealing cap, after fastening described bolt is installed, cover described sealing cap, form an integral body with described rotatable round overcoat, top cambered surface in addition, fairshaped appearance is had no way of doing it the lawless person; Described sealing cap intracavity bottom arranges groove, and the edge of described clamping block can fold into described groove in the time of fastening, has increased join strength, effectively prevents from becoming flexible, coming off.The utility model arranges quadrilateral to described bolt, has also saved fabricating cost to a certain extent, and anti-theft effect is obvious simultaneously, has increased the safe operation reliability of circuit.The utility model is simple in structure, and is convenient and practical, and the Safety performance height is convenient to generally promote the use of.
Description of drawings
The utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
