Abstract
The invention discloses a coupling. The coupling comprises an outer sleeve, an inner sleeve and a positioning drum, wherein the outer sleeve is sleeved outside the inner sleeve and is in sliding fit with the inner sleeve; and the positioning drum is sleeved outside the outer sleeve and is fit with the outer sleeve. The coupling has the following beneficial effects: couplings can be sleeved together to form a whole, the length is only half the original one, and the coupling is convenient to install without centering during installation.
Description
Technical field
The present invention relates to the coupling technical field.
Background technique
The complicated difficulty of existing coupling dismounting sometimes also will move axle to be connected, installs and also will carry out the heart.
Summary of the invention
A kind of coupling of the present invention can make coupling be nested together, and forms one, and length only has original half, the convenient installation, and needn't be to the heart when installing.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of coupling comprises outer sleeve, inner sleeve and location cylinder,
It is outside that described outer sleeve is enclosed within described inner sleeve, be slidingly matched with described inner sleeve,
It is outside that described location cylinder is enclosed within described outer sleeve, cooperates with described outer sleeve.
Further, described location cylinder and described outer sleeve screw-thread fit.
Further, in the end of described outer sleeve positive stop strip is installed, in described positive stop strip end positioning wedged block is installed,
Be provided with locating groove at described inner sleeve outer wall,
Described positioning wedged block cooperates with described locating groove.
Further, described positive stop strip has four to be evenly distributed on described outer sleeve end,
Described locating groove has four, is evenly distributed on the described inner sleeve outer wall.
Structural design of the present invention forms one so that coupling is nested together, and length only has original half, the convenient installation, and needn't be to the heart when installing.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the described a kind of coupler structure schematic representation of the embodiment of the invention.
Fig. 2 is schematic representation after the described a kind of coupling of the embodiment of the invention connects.
Embodiment
As shown in Figure 1 and Figure 2, the described a kind of coupling of the embodiment of the invention comprises outer sleeve 1, inner sleeve 2 and location cylinder 3,
Outer sleeve 1 is enclosed within inner sleeve 2 outsides, is slidingly matched with inner sleeve 2,
Location cylinder 3 is enclosed within outer sleeve 1 outside, cooperates with outer sleeve 1.
Location cylinder 3 and outer sleeve 1 screw-thread fit.
In the end of outer sleeve 1 positive stop strip 11 is installed, in positive stop strip 11 ends positioning wedged block 111 is installed,
Be provided with locating groove 21 at inner sleeve 2 outer walls,
Positioning wedged block 111 cooperates with locating groove 21.
Locating groove 21 has four, is evenly distributed on inner sleeve 2 outer walls.
In use, outer sleeve 1 is enclosed within first an end with coupling shaft and fixes, then inner sleeve 2 is pulled out from outer sleeve 1 inside, be fixed on another root band coupling shaft, rotation location cylinder 3 moves to inner sleeve 2 directions, to pressing down, positioning wedged block 111 is cooperated with locating groove 21 positive stop strip 11 that slightly is upturned, to inner sleeve 2 location, finish connection.
Structural design of the present invention forms one so that coupling is nested together, and length only has original half, the convenient installation, and needn't be to the heart when installing.
