Abstract

The utility model discloses a connecting sleeve easy to be assembled and disassembled. The connecting sleeve comprises a hollow cylindrical sleeve body (1), wherein a thread (3) is arranged on the inner wall of the sleeve body (1), jacks (2) are arranged at the upper part of the sleeve body (1) and penetrate through the wall of the sleeve body (1), every two jacks (2) are in a group, and each group of jacks (2) are positioned on the same diameter, and the jack (2) is a square hole or a circular hole. With the adoption of the structure, the connecting sleeve can be assembled and disassembled more conveniently; and meanwhile, the labor is saved.

Description

A kind of coupling sleeve that is easy to installation and removal
Technical field
The utility model relates to a kind of sleeve, specifically is a kind of coupling sleeve that is easy to installation and removal.
Background technique
At present, coupling sleeve is general, and what adopt is straight thread, promptly is on the whole inwall of coupling sleeve screw thread to be set; The end surface of connected two links is provided with outside thread, during operation, coupling sleeve is socketed in the end of one of them link; And the sleeve that is rotatably connected is to correct position; Then the other end of coupling sleeve is socketed in the end of another link, rotates this link, finally accomplish two to be connected connection work.This Placement is saved steel, does not receive the restriction of weldability of steel bar, and the quality of connection reliability is higher, is applicable to the connection of any threaded link.But when the big perhaps quality of link diameter was big, general sleeve was not easy rotation, was easy to skid, and because the link quality is bigger, and rotary connector is required great effort very much, operated relatively difficulty, and simultaneously, link is difficult for taking off after connecting, and dismounting is effort very; Sometimes we need not be fixed on two to be connected on the coupling sleeve.
The model utility content
The utility model technical problem to be solved is that simple to operate, a kind of coupling sleeve that is easy to installation and removal in labour-saving is provided.
The utility model is that the technical solution problem mainly realizes through following technological scheme: a kind of coupling sleeve that is easy to installation and removal; The sleeve body that comprises hollow cylinder; The inwall of sleeve body is provided with screw thread, and said sleeve body top is provided with jack, and jack penetrates the wall of sleeve body; Said jack is one group in twos, and each group jack is positioned on the same diameter.Swing arm passes the central shaft of sleeve body, makes same swing arm reach the longest arm of force, rotate lighter, screw thread on the inwall of sleeve body and the threads engaged on the link, jack is used to insert swing arm, is beneficial to the turnbarrel body.
Said jack is positioned on the same circumference horizontal plane.Swing arm is perpendicular to sleeve body, and the rotating force that sleeve body is obtained reaches maximization.
Said jack has one group at least.
Said screw thread is positioned at the below of jack place circumference horizontal plane.Internal thread only is distributed in an end of sleeve body; The other end does not need screw thread; So only need be with one of them to be connected through being threaded on the sleeve body; Another to be connected insertion sleeve body is interior with being fixedly coupled part to withstanding on then, promptly accomplishes the attended operation unit.
Said jack is square opening or circular port.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model improves the inner thread of coupling sleeve, is in the past on the whole inwall screw thread to be set, and improves the back part screw thread only is set on inwall; When connecting, only need a to be connected trustship screw thread be fixed on an end of coupling sleeve, another to be connected is inserted coupling sleeve and gets final product; Therefore, need two to be connected all be fixed on the coupling sleeve through screw thread, simplify operation reaching on the basis that connects effect; Simultaneously, dismounting is also very convenient.
(2) the utility model is provided with jack on the basis of original coupling sleeve, makes things convenient for inserting of swing arm, makes the coupling sleeve rotation more easily laborsaving.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the worm's eye view of the utility model.
Pairing reference character is in the accompanying drawing: 1, sleeve body, 2, jack, 3, screw thread.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the mode of execution of the utility model is not limited thereto.
Embodiment:
Like Fig. 1 and shown in Figure 2, the utility model comprises the sleeve body 1 of hollow cylinder, and the inwall of sleeve body 1 is provided with screw thread 3; Said sleeve body 1 top is provided with jack 2; The wall jack 2 that jack 2 penetrates sleeve body 1 is square opening or circular port, is used to insert swing arm, and jack 2 is one group in twos; And each group jack 2 is positioned on same the diameter of same circumference horizontal plane; Swing arm passes the center line that one group of jack 2 just also passes sleeve body 1, and as preferably, the jack 2 of present embodiment is two groups; Screw thread 3 is positioned at the below of jack 2 place circumference horizontal planes.
The working principle of the utility model is: at first, swing arm is inserted in jack 2, sleeve body 1 is socketed in has on externally threaded to be connected then; To the swing arm application of force; Through screw thread 3 sleeve body 1 is rotated to be connected direction, and then fixing to be connected, pull up swing arm; With another to be connected the other end that inserts sleeve body 1, promptly accomplish connection work; During the dismounting link, an end of link is extracted in sleeve body 1, then swing arm is inserted in the jack 2, turnbarrel body 1 spins down sleeve body 1 from another link, promptly accomplish dismantlement work.
As stated, then can realize the utility model well.
