Technical Field

[0001] The utility model provides a coupling and relates to the technical field of couplings. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads, thus playing a role in overload protection.

[0003] The patent with the patent authorization announcement number CN209385519U discloses a quick-install coupling. The first half coupling and the second half coupling are rotatably connected to each other through a cylinder, and the first locking block and the second locking block are connected by screws, which can realize a quick installation connection between two pipe fittings, and the pipe fitting connection is higher.

[0004] However, the coupling provided by the patent still has shortcomings in actual use. The coupling requires the two pipe fittings to be aligned in their axes before they can be connected, and cannot connect two pipe fittings with offset axes. Therefore, it is necessary to provide a coupling that can connect two pipe fittings with misaligned axes. Utility Model Content

[0009] More preferably, it further comprises: a first rivet, and the connecting column and the connecting seat are riveted together by a plurality of the first rivets.

[0010] More preferably, the number of the first rivets and the number of the second rivets are both 6.

[0011] More preferably, it further comprises: a screw, and the screw is threadedly arranged on the connecting seat.

[0012] More preferably, the screw is longer than the thickness of the connecting seat.

[0013] More preferably, the screw is of hexagon socket type.

[0014] More preferably, it further comprises: an easy-slip chamfer, and the easy-slip chamfer is provided at the connecting hole of the connecting seat.

[0015] More preferably, it further comprises: an anti-skid protrusion, the anti-skid protrusion is fixedly connected to the connecting seat, and the anti-skid protrusion is arranged in the connecting hole.

[0016] Compared with the prior art, the coupling provided by the embodiment of the utility model has the following advantages: 1. Through the arrangement of the rubber ring and the cavity, the rubber ring can be bent and deformed to offset the two connecting seats so as to connect two pipes with misaligned axes, thereby achieving the effect of connecting two pipes with misaligned axes.

[0017] 2. By setting the first rivet, the connection seat can be removed and replaced with a connection seat with a different connection hole diameter, thereby achieving the effect of replacing the connection seat.

[0018] 3. By setting the second rivet and the rivet interface, the rubber ring is separated from the connection with the two connecting columns, and a new rubber ring can be replaced, thereby achieving the effect of replacing the rubber ring.

[0019] 4. By setting the easy-slip chamfer, the pipe fitting can be guided so that the pipe fitting can slide into the connecting hole more easily, thereby achieving the effect of facilitating the pipe fitting to enter the connecting hole.

[0020] 5. By setting the anti-slip bump, the friction between the connecting hole and the pipe fitting can be increased, thereby preventing the pipe fitting from rotating in the connecting hole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1: A coupling, see Figure 1-Figure 3 As shown, it includes: a connecting seat 1, there are two connecting seats 1, a circular connecting hole 101 is opened at one end of the two connecting seats 1 away from each other, four connecting columns 3 are installed on the side of the two connecting seats 1 close to each other, and a rubber ring 5 is installed between the connecting columns 3 on the two connecting seats 1, and the middle part of the rubber ring 5 is a cavity 501, so that the rubber ring 5 can be bent and deformed.

[0026] When two pipes need to be connected, the two pipes are connected by inserting them into the connecting holes 101 of the two connecting seats 1, and rotating the screw 2 to press the pipes against the inner wall of the connecting hole 101 to tighten the pipes. When the axes of the two pipes are not aligned, the two connecting seats 1 can be bent and offset by the rubber ring 5 on the connecting column 3. At this time, the rubber ring 5 is deformed. The setting of the cavity 501 enables the rubber ring 5 to be bent and deformed more easily, and then the pipe can be inserted into the connecting hole 101.

[0027] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes: a first rivet 4, the connecting column 3 and the connecting seat 1 are riveted together by six of the first rivets 4, a screw 2 is threadedly arranged on the connecting seat 1, and the screw 2 is longer than the thickness of the connecting seat 1, so that the screw 2 can fix a thinner pipe fitting, and the screw 2 is a hexagonal style, and the screw 2 can be rotated by using a hexagonal iron. When the diameter of the pipe fitting is greater than the diameter of the connecting hole 101, the first rivet 4 can be removed to replace the connecting seat 1 with a larger connecting hole 101, and the pipe fitting can be riveted and fixed in the connecting hole 101 by the screw 2.

[0028] See also Figure 3 As shown, it also includes: a rivet interface 601, a plurality of rivet interfaces 601 are opened on the connecting column 3, and the first rivet 4 and the second rivet 6 are both 6, so that the connection of the connecting column 3 is more stable, and the rubber ring 5 is riveted and fixed on the two opposite connecting columns 3 through the second rivet 6, and the second rivet 6 is riveted in the rivet interface 601. When the rubber ring 5 is frequently bent, the rubber ring 5 is easily worn and torn. At this time, the second rivet 6 can be taken out from the rivet interface 601 to replace the new rubber ring 5.

[0029] See also Figure 2 As shown, it also includes: an easy-slip chamfer 102. The easy-slip chamfer 102 is provided at the connection hole 101 of the connection seat 1. When the pipe enters the connection hole 101, the easy-slip chamfer 102 can guide the pipe to make it easier to slide into the connection hole 101.

[0030] See also Figure 2 As shown, it also includes: an anti-skid protrusion 103, which is fixedly connected to the connecting seat 1 by mold injection molding. The anti-skid protrusion 103 is arranged in the connecting hole 101, and the anti-skid protrusion 103 is used to increase the friction between the connecting hole 101 and the pipe fitting to prevent the pipe fitting from rotating in the connecting hole 101.
