Description

Technical Field

[0001] The utility model relates to the technical field of coupling structures, and more specifically, to a coupling structure for an automatic knob rod. Background Art

[0002] A coupling is used to firmly connect the driving shaft and the driven shaft in different mechanisms. When the driving shaft rotates, it can drive the coupling to rotate, and then drive the driven shaft to rotate through the coupling. In a liquid packaging production line, a knob rod is needed to open the top cover of an empty box, and then the liquid can be transported into the empty box for packaging. This requires the knob rod to rotate, so a coupling structure is needed to make the knob rod rotate. However, in the prior art, the connection of the coupling structure is not tight enough during use, which leads to looseness and other situations during the use of the coupling.

And through the arrangement of the first cutting groove 5 and the second cutting groove 12, after the mounting bolt 16 is screwed into the inner cavity of the threaded groove 6, the driven mounting shaft 1 and the driving mounting shaft 11 can undergo slight deformation, thereby enabling the first clamping block 2, the middle clamping block 8, and the second clamping block 15 to be tightened, and also enabling the driven mounting shaft 1 and the driving mounting shaft 11 to clamp the driving shaft or the driven shaft.

[0041] In an embodiment of the present utility model, both the first clamping block 2 and the second clamping block 15 are arc-shaped bodies, and the driving mounting shaft 11 is located above the driven mounting shaft 1;

[0042] The beneficial effects of adopting the above technical solution are as follows: Since both the first clamping block 2 and the second clamping block 15 are arc-shaped bodies, after the first clamping block 2 and the second clamping block 15 are inserted together, the whole presents a cylindrical shape.

[0049] In one embodiment of the present invention, both the driven mounting shaft 1 and the active mounting shaft 11 are provided with chamfers 13 on the side away from the middle ring 7;

[0050] The beneficial effect of adopting the above technical solution is that the sharpness of the driven mounting shaft 1 and the active mounting shaft 11 is reduced by setting the chamfer 13, thereby avoiding the situation where the staff are cut when taking the driven mounting shaft 1 and the active mounting shaft 11.

[0051] In one embodiment of the present invention, the first clamping block 2 and the second clamping block 15 have the same volume, and the interval between two adjacent middle clamping blocks 8 has the same volume as the first clamping block 2;

[0052] The beneficial effect of adopting the above technical solution is that, because the volumes of the first clamping block 2 and the second clamping block 15 are the same, and the interval of the middle clamping block 8 is the same as the volume of the first clamping block 2, the first clamping block 2 and the second clamping block 15 can be tightly inserted into the interval of the middle clamping block 8, thereby improving the stability of the connection between the driven mounting shaft 1, the middle ring 7, and the active mounting shaft 11.

[0054] Then, insert the drive shaft of the driving device into the inner cavity of the second mounting groove 4, and then insert the driven shaft into the inner cavity of the first mounting groove 3;

[0055] Then, screw two mounting bolts 16 into the inner cavity of the threaded grooves 6 of the driven mounting shaft 1 and the driving mounting shaft 11. At this time, through the first slotted groove 5, the driven mounting shaft 1 undergoes slight deformation, and the second slotted groove 12 causes the driving mounting shaft 11 to undergo slight deformation, thereby making the first clamping blocks 2, the middle clamping block 8, and the second clamping blocks 15 closer, and the first mounting groove 3 and the second mounting groove 4 wrap the driven shaft and the driving shaft more tightly, thus completing the connection between the driven mounting shaft 1 and the driving mounting shaft 11.
