Abstract
The utility model discloses an internal diameter tensioning device. The internal diameter tensioning device is characterized in that the tensioning device comprises a left shaft body and a right shaft body, the left shaft body is connected and locked with the right shaft body via a shaft sleeve, external threads are respectively arranged in the left and the right shaft bodies, and an internal thread matched with the external threads of the left and the right shaft bodies is arranged in the shaft sleeve. The internal diameter tensioning device is advantaged by reasonable structure and design, low manual labor intensity, time saving and labor saving, and high work efficiency during an installation process, and the tensioning device is a special internal diameter tensioning device which can meet the usage requirement.
Description
Technical field
The utility model relates to a kind of tension device, relates in particular to a kind of internal diameter tension device.
Background technology
When the larger mouth of pipe of internal diameter or channel-section steel internal diameter are carried out to tensioner, mostly manually to utilize simple instrument to carry out carrying out piecemeal tensioner along the mouth of pipe or channel-section steel internal diameter,, in prior art, also there is not special-purpose tension device in its troublesome poeration, time saving and energy saving, inefficiency.
Utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, a kind of internal diameter tension device is provided, for special-purpose internal diameter tension device, when having solved the mouth of pipe that internal diameter is larger or channel-section steel internal diameter and having carried out tensioner, the problem such as troublesome poeration, time saving and energy saving, inefficiency.
The utility model is achieved through the following technical solutions:
A kind of internal diameter tension device, it is characterized in that: include left and right axis body, between described left and right axis body, by axle sleeve, connect locking, the inner of described left and right axis body is respectively equipped with external screw thread, is provided with the internal thread coordinating with left and right axis body external screw thread in described axle sleeve.
The middle part of described axle sleeve is provided with the jack of fixing auxiliary rotation latch.
The outer face of described left and right axis body is respectively spherical or plane.
Its principle is: by left and right axis body and between the rotation of axle sleeve coordinate, during use, only need to by left and right axis body and between the integral body that forms of axle sleeve, be positioned in the mouth of pipe or between channel-section steel internal diameter, then by rotary sleeve, left and right axis body is stretched out, can reach tensioner; In process, hand labor intensity is little, time saving and energy saving, operating efficiency is high, and the outer face of left and right axis body is respectively spherical or plane, can be according to the end face of the different corresponding matching of the Object Selection of tensioner, as: the line up internal diameter outer face by left and right axis body is respectively coordinating of the convenient and spout diameter of the structural design of spherical.
The utility model has the advantages that:
The utility model reasonable in design, for special-purpose internal diameter tension device, installs and uses aspect in process, hand labor intensity is little, time saving and energy saving, and operating efficiency is high, has met instructions for use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, a tension device, includes left and right axis body 1,2, between left and right axis body 1,2, by axle sleeve 3, connects locking, the inner of left and right axis body 1,2 is respectively equipped with external screw thread, is provided with the internal thread coordinating with left and right axis body 1,2 external screw threads in axle sleeve 3; The middle part of axle sleeve 3 is provided with the jack 4 of fixing auxiliary rotation latch; The outer face of left and right axis body 1,2 is respectively spherical or plane.
