For achieving the above object, the utility model have employed following technical proposal: this universal quick change transmission coupling comprises connecting shaft cylinder, the lever that the shaft axis being provided with shaft axis and connecting shaft cylinder in connecting shaft cylinder distributes in " ten " font, this coupling also comprises one end and can insert in the connecting shaft head in described connecting shaft cylinder and overlap with connecting shaft cylinder shaft axis when this connecting shaft head inserts in described connecting shaft head shaft axis after in connecting shaft cylinder, the draw-in groove snapped in for described lever is provided with in connecting shaft head one end inserted in connecting shaft cylinder, described connecting shaft cylinder connects position structure by first to be fixed, described connecting shaft head connects position structure by second to be fixed.
In this application, dismounting difficulty can be reduced further owing to being provided with connecting shaft cylinder and lever in conjunction with the structure of connecting shaft head and draw-in groove, structure simple and change convenient, practical.To be connected position structure with second and can be convenient to install owing to being provided with the first connection position structure and to connect.
In above-mentioned universal quick change transmission coupling, described lever two ends to be located in the middle part of connecting shaft cylinder on inwall respectively.
In above-mentioned universal quick change transmission coupling, described first connects position structure comprises the internal thread being arranged on connecting shaft cylinder outer end inner wall.
In above-mentioned universal quick change transmission coupling, described connecting shaft cylinder inwall is also provided with the annular prevent surface be positioned at inside internal thread.
In above-mentioned universal quick change transmission coupling, described second connects position structure comprises and is arranged on connecting shaft head and is provided with ladder positioning step away from one end of draw-in groove.
In above-mentioned universal quick change transmission coupling, described connecting shaft centriciput is provided with the annular protrusion stop part be positioned at inside ladder positioning step.
In above-mentioned universal quick change transmission coupling, one end that described connecting shaft head inserts in connecting shaft cylinder is provided with chamfering.
Compared with prior art, the advantage of this universal quick change transmission coupling is: 1, design is more reasonable, dismounting difficulty can be reduced further owing to being provided with connecting shaft cylinder and lever in conjunction with the structure of connecting shaft head and draw-in groove, structure simple and change convenient, practical.To be connected position structure with second and can be convenient to install owing to being provided with the first connection position structure and to connect.2, structural strength is high.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation that the utility model provides.
In figure, connecting shaft cylinder 1, internal thread 11, annular prevent surface 12, lever 2, connecting shaft head 3, draw-in groove 31, ladder positioning step 32, annular protrusion stop part 33, chamfering 34.
Embodiment
Be below the specific embodiment of model utility and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this universal quick change transmission coupling comprises connecting shaft cylinder 1, the lever 2 that the shaft axis being provided with shaft axis and connecting shaft cylinder 1 in connecting shaft cylinder 1 distributes in " ten " font, optimized project, lever 2 two ends of the present embodiment to be located in the middle part of connecting shaft cylinder 1 on inwall respectively.
This coupling also comprises one end and can insert in the connecting shaft head 3 in described connecting shaft cylinder 1 and overlap with connecting shaft cylinder 1 shaft axis when this connecting shaft head 3 inserts in described connecting shaft head 3 shaft axis after in connecting shaft cylinder 1, is provided with chamfering 34 in connecting shaft head 3 one end inserted in connecting shaft cylinder 1.Chamfering 34 plays the effect of guiding.Be provided with the draw-in groove 31 snapped in for described lever 2 in connecting shaft head 3 one end inserted in connecting shaft cylinder 1, realize after in the draw-in groove 31 that lever 2 is stuck in connecting, can prevent circumference each other from mutually rotating.
Connecting shaft cylinder 1 connects position structure by first to be fixed.Particularly, first of the present embodiment connects position structure and comprises the internal thread 11 being arranged on connecting shaft cylinder 1 outer end inner wall, and internal thread 11 effective length is 1/4 of connecting shaft cylinder 1 length.Internal thread 11 with there is externally threaded axle be connected.Connecting shaft cylinder 1 inwall is also provided with the annular prevent surface 12 be positioned at inside internal thread 11.Annular prevent surface 12 can prevent having the excessively movement of externally threaded axle.
