Abstract
A kind of multiple safety tension device and special spanner thereof, its multiple safety tension device is through Anti-theft casing (3) by screw rod two ends, screw rod is established nonstandard nut (5), the inner nut pipe plug (4) of central zone circular hole (7) is established in one end of above-mentioned Anti-theft casing, and Anti-theft casing is established multiple ventilation spilled water hole (2).Its special spanner is " L " shape, and the shape of one end is corresponding with above-mentioned nonstandard nut (5), and the other end is corresponding with above-mentioned inner nut pipe plug (4) shape.This device is for the screw rod of tensioning and nut peripheral hardware Anti-theft casing, and both antitheft, waterproof again, uses nonstandard nut, and general spanner can not be dismantled, and reaches the object of multiple safety.Use this device tension equipment, connection device is safe and reliable, reduces maintenance cost.Sleeve pipe there is ventilating drainage hole, the ponding in pipe can be discharged in time, avoid corrosion.
Description
Technical field
The utility model relates to a kind of tension device, be specifically a kind ofly relate at highway, railway, electric power is widely used tightens stretching for line or be stitched together and the antitheft tension device strained by two objects.
Background technique
Present tension device, is arranged on desired position, non-watertight, non-anti-theft, and corrosion affects its open function, and the equipment that sometimes affects after loss normally runs, and brings larger workload to maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of multiple safety tension device and special spanner thereof, and it could be dismantled with special spanner, and has Anti-theft casing, waterproof, antitheft, and reliability is high, reduces the human and material resources cost of plant maintenance.
The technical solution of the utility model is as follows:
A kind of multiple safety tension device and special spanner thereof, multiple safety tension device is made up of screw rod, Anti-theft casing, nonstandard nut, inner nut pipe plug; Above-mentioned screw rod two ends are through Anti-theft casing, and screw rod is established nonstandard nut, and the inner nut pipe plug of central zone circular hole is established in one end of above-mentioned Anti-theft casing, and Anti-theft casing is established multiple ventilation spilled water hole.
Above-mentioned inner nut pipe plug establishes three holes be evenly arranged.
The ventilation spilled water hole of above-mentioned Anti-theft casing is 2 ~ 4.
A kind of multiple safety tension device and special spanner thereof, its special spanner is " L " shape, and the shape of one end is corresponding with above-mentioned nonstandard nut, and the other end is corresponding with above-mentioned inner nut pipe plug shape.
Above-mentioned special spanner, connects and composes " L " shape by tubular portion and steel plate, and the termination right and wrong mark nut shape of tubular portion is corresponding, for nut nonstandard in stubborn sleeve pipe; The termination of steel plate is corresponding with inner nut pipe plug shape, and it has three projections, for stubborn inner nut pipe plug with the hole corresponding position of inner nut pipe plug.
The utility model has the advantage of: 1, this device is for the screw rod of tensioning and nut peripheral hardware Anti-theft casing, and both antitheft, waterproof again, uses nonstandard nut, and general spanner can not be dismantled, and reaches the object of multiple safety.Use this device tension equipment, connection device is safe and reliable, reduces maintenance cost.2, sleeve pipe there is ventilating drainage hole, the ponding in pipe can be discharged in time, avoid corrosion.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Can be seen by Fig. 1 ~ 3, a kind of multiple safety tension device, it is made up of screw rod 1, Anti-theft casing 3, nonstandard nut 5, inner nut pipe plug 4; Above-mentioned screw rod two ends are through Anti-theft casing 3, and screw rod is established nonstandard nut 5, and the inner nut pipe plug 4 of central zone circular hole 7 is established in one end of above-mentioned Anti-theft casing, and three uniform holes 6 are established in the outside of inner nut pipe plug, and Anti-theft casing is established 4 spilled water holes 2 of ventilating.
Can be seen the special spanner of this tension device by Fig. 3 ~ 6, it is " L " shape, is connected and composed by tubular portion 9 and full-elliptic 11, and the termination 10 right and wrong mark nut shape of tubular portion is corresponding, for nut nonstandard in stubborn sleeve pipe; There are three projections 12 termination 8 of steel plate, for stubborn inner nut pipe plug with three hole 6 corresponding positions of inner nut pipe plug.
Can be seen the using state of this device by Fig. 7, be connected one end of the screw rod 1 of this device with fixed end 14, one end is connected with needing the object 13 of tensioning.The object of tensioning object is reached by nut nonstandard in stubborn sleeve pipe.
Fixed end 14 can adopt various ways, fix, or the two column of " one " shape connection is fixed, or single column screw rod being penetrated column is fixed as " V " shape connects two column.
Be connected with needing the object of tensioning to adopt and weld or nut Placement.
