[0002] A coupling is a mechanical part used to connect two shafts in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are connected to the driving shaft and the driven shaft respectively. Generally, most power machines are connected to the working machine with the help of couplings. There are many types of couplings, and the scope of their action will also be different.

[0003] In the prior art, couplings are mostly fixedly connected by threads. However, during use, since a plurality of threaded holes are provided on the coupling, the threaded holes need to be aligned and then the threads need to be rotated for fixing. This makes it difficult to quickly position and connect the coupling, thereby reducing the use efficiency of the coupling. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a coupling with a positioning installation structure, which has the advantage of rapid positioning and avoids the problem of slow positioning and low efficiency.

[0007] The side wall of the connecting cylinder is slidably connected with a plurality of clamping columns, and the side wall of the clamping column located in the inner cavity of the connecting cylinder is fixedly connected with a connecting plate, and a spring is fixedly connected between the connecting plate and the inner wall of the connecting cylinder, and the spring is located outside the clamping column.

[0008] According to some embodiments, a plurality of clamping holes are formed on the side wall of the shaft body, and the clamping column can extend to the inner cavity of the clamping hole.

[0009] According to some embodiments, the shaft body and the end of the clamping column are both configured to be conical, and the shaft body can extend to the inner cavity of the connecting tube.

[0010] According to some embodiments, the side wall of the connecting tube located outside the clamping column is clamped with a first ring sleeve and a second ring sleeve, and both the first ring sleeve and the second ring sleeve are in contact with the side wall of the connecting tube.

[0011] According to some embodiments, the first ring sleeve and the second ring sleeve side walls are both fixedly connected with square blocks, and the side walls of the square blocks are threadedly connected with first threaded bolts.

[0012] According to some embodiments, the clamping columns and the clamping holes are evenly distributed along the central axis of the main body and correspond one to one.

[0013] According to some embodiments, a cross block is fixedly connected to the bottom of the connecting tube, and the cross block can extend to the inner wall of the main body.

[0014] According to some embodiments, the side wall of the cross clamp is threadedly connected with a plurality of second threaded bolts, and the cross clamp and the main body are fixedly connected by the second threaded bolts.

[0015] Beneficial Effects

[0016] The utility model provides a coupling with a positioning installation structure, which has the following beneficial effects:

[0017] The coupling with a positioning and installation structure inserts the shaft body into the inner cavity of the connecting tube, and the shaft body squeezes the clamping column to slide to the outside of the connecting tube. At this time, the spring located between the connecting plate and the connecting tube will be squeezed to generate a rebound force until the clamping column slides to the inner cavity of the connecting tube, and the shaft body will continue to slide to the bottom of the connecting tube. At this time, the shaft body is rotated again, and when the clamping hole opened on the side wall of the shaft body rotates to the bottom of the clamping column, under the action of the rebound force of the spring, the clamping column will slide to the inner cavity of the clamping hole opened on the side wall of the shaft body to complete the clamping connection, thereby facilitating the positioning and installation of the shaft body.

[0028] It should be noted that: first, after selecting the connecting cylinder 101 according to the size of the shaft body 102, the connecting cylinder 101 is clamped on the side walls of the main body 1, and then the shaft body 102 is inserted into the inner cavity of the connecting cylinder 101. After the shaft body 102 is inserted, it will contact the clamping column 2. Since the ends of the shaft body 102 and the clamping column 2 are both set to be conical, after the shaft body 102 contacts the clamping column 2, the shaft body 102 will squeeze the clamping column 2 to slide to the outside of the connecting cylinder 101. At this time, the connecting plate 201 and the connecting cylinder are located The spring 202 between 101 will be squeezed to generate a rebound force until the clamping column 2 slides into the inner cavity of the connecting tube 101, and the shaft body 102 will continue to slide to the bottom of the connecting tube 101. At this time, the shaft body 102 is rotated again. When the clamping hole 203 opened on the side wall of the shaft body 102 rotates to the bottom of the clamping column 2, under the action of the rebound force of the spring 202, the clamping column 2 will slide into the inner cavity of the clamping hole 203 opened on the side wall of the shaft body 102 to complete the clamping, thereby facilitating the positioning of the shaft body 102 when installing.

Then, insert the shaft body 102 into the inner cavity of the connecting tube 101. After the shaft body 102 is inserted, it will contact with the clamping column 2. Since the ends of the shaft body 102 and the clamping column 2 are both set to be conical, after the shaft body 102 contacts the clamping column 2, the shaft body 102 will squeeze the clamping column 2 to the outside of the connecting tube 101 Sliding, at this time, the spring 202 located between the connecting plate 201 and the connecting cylinder 101 will be squeezed to generate a rebound force, until the clamping column 2 slides to the inner cavity of the connecting cylinder 101, and the shaft body 102 will continue to slide to the bottom of the connecting cylinder 101. At this time, the shaft body 102 is rotated again. When the clamping hole 203 opened on the side wall of the shaft body 102 rotates to the bottom of the clamping column 2, under the action of the rebound force of the spring 202, the clamping column 2 will slide to the inner cavity of the clamping hole 203 opened on the side wall of the shaft body 102 to complete the clamping connection, thereby facilitating the positioning of the shaft body 102 when installing;
