[0028] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0029] A rotating connection, referring to Figure 1 、 Figure 2 , including a connecting seat 1, the upper end surface of the connecting seat 1 is fixedly connected with two connecting heads 2 for extending into the rotating member, and the lower end surface of the connecting seat 1 is provided with a square groove 3 for being sleeved on the rotating shaft.

[0030] Reference Figure 1 The two connectors 2 extend vertically away from the connection base 1. The opposing sides of the two connectors 2 are each provided with an arcuate surface 5, to which a claw 6 is fixedly attached. The claw 6 extends toward the connection base 1, with the extended end gradually moving away from the connector 2. The rotating member has two mounting holes for the connectors 2, and the inner walls of the mounting holes have limit slots. When the connector 2 is inserted into the mounting holes, the two claws 6 engage in the corresponding limit slots.

[0031] A fixing ring 7 is axially fixedly connected to the side wall of the connector base 1. The fixing ring 7 has a plurality of through holes 8 arranged along the circumference of the connector base 1. After the connector 2 is inserted into the component, the fixing ring 7 abuts against the outer wall of the component, and bolts can be inserted into the plurality of through holes 8 to further secure the connector to the component.

[0032] Reference Figure 2 、 Figure 3 The outer wall of the connection base 1 is radially penetrated by a plurality of pressure-resistant holes 9, which are evenly arranged along the circumference of the connection base 1. The connection base 1 has an interior provided with an installation cavity 10 interconnected with the plurality of pressure-resistant holes 9, and the installation cavity 10 contains a plurality of thermal expansion and contraction balls 11, the same number as the pressure-resistant holes 9.

[0033] Reference Figure 3 The diameter of the thermal expansion and contraction ball 11 at room temperature is slightly larger than the diameter of the pressure-resistant hole 9. After being refrigerated, the thermal expansion and contraction ball 11 is installed from the pressure-resistant hole 9 into the installation cavity 10. During the rotation process, the thermal expansion and contraction ball 11 is stuck to the opening of the pressure-resistant hole 9 on the inner wall of the installation cavity 10 due to centrifugal force. When the equipment has abnormal shaking, the thermal expansion and contraction ball 11 will jump in the installation cavity 10 under the action of inertia, thereby generating a knocking sound, which serves as a maintenance prompt.

[0034] Reference Figure 2、 Figure 3 The lower end surface of the connecting base 1 is provided with a guide sliding surface 12 along the opening of the square groove 3, and the guide sliding surface 12 is recessed toward the bottom of the square groove 3. The connecting base 1 is provided with an insertion port 4 that passes through the square groove 3. When the rotating shaft is sleeved on the square groove 3, it is fixed to the connecting base 1 through the insertion hole 4.

[0035] A circular groove 13 is formed at the bottom of the square groove 3 and is connected thereto. The diameter of the circular groove 13 is the same as the width of the square groove 3, so that the circular rotating shaft can pass through the square groove 3 and extend into the circular groove 13. In addition, an internal thread 14 is provided on the inner wall of the circular groove 13, which can be threadedly connected to the rotating shaft extending into the circular groove 13.

[0036] The implementation principle of the embodiment of the present application is: the connecting head 2 is inserted into the rotating part, and the claw 6 abuts against the rotating part to position the connecting part and the rotating part. After positioning, the fixing ring 7 can be directly connected and fixed to the rotating part by bolts, which can effectively improve the connection efficiency between the connecting part and the rotating part.

[0037] In addition, the connecting base 1 can be connected to a square or round rotating shaft and can effectively adapt to a variety of rotating motors.
