the end part of the spring is clamped in the insertion groove;

wherein, one side of the inserting groove is provided with an opening which is gradually enlarged along the direction from the inside to the outside of the inserting groove, the groove wall of the insertion groove positioned at the opening and the bottom surface of the insertion groove are in transition through an inclined plane so as to facilitate the end part of the spring to enter.

Preferably, the number of the flange plates is two, and two ends of the spring are respectively clamped in the insertion grooves of the two flange plates.

Preferably, a through hole is formed in the middle of the flange plate and used for a shaft to pass through.

Preferably, the method further comprises the following steps:

the fastener is arranged on the side wall of the flange plate in a penetrating mode and communicated with the through hole, and the fastener is matched with the flange plate and can clamp the shaft.

Preferably, the number of the fastening pieces is two, and the two fastening pieces are arranged in an intersecting manner.

Preferably, the fastener is a screw.

Preferably, the distance between the top ends of the two slot walls of the insertion slot is smaller than the distance between the bottom ends of the two slot walls.

Preferably, the flange plate is further provided with a connecting disc, and the spring is sleeved on the connecting disc.

Compared with the prior art, the beneficial effects of the utility model are that: through being in the opening part set up the inclined plane transition between the cell wall of inserting groove and the bottom surface of inserting groove for when installing, the bottom of the link of spring can the butt the inclined plane, then via in the inclined plane inserts the inserting groove, like this, it is more convenient when the spring is installed on the ring flange.

Detailed Description

To make the objects, technical solutions and advantages of the present invention clearer, the drawings in the present invention will be combined to clearly and completely describe the technical solutions of the present invention, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the embodiment of the present application provides a spring coupling, which includes a flange plate 10, a spring 20, a connecting plate 30, and a fastening member 40, wherein a through hole 11 is provided in the middle of the flange plate 10 for a shaft to pass through, two flange plates 10 are provided at two ends of the spring 20 and connected to the spring 20, the two flange plates 10 connect the two shafts together, and the fastening member 40 fastens the shaft to prevent the shaft from falling off from the flange plates 10.

Specifically, the side wall 13 of the flange plate 10 is provided with the insertion groove 12, the spring 20 is sleeved on the connection disc 30, and the end portion of the spring 20 is clamped in the insertion groove 12, it should be understood that the end portion of the spring 20 refers to the connection end of the spring 20, an opening on one side of the insertion groove 12 is arranged, the opening gradually increases in the direction from the inside to the outside of the insertion groove 12, the groove wall 121 of the insertion groove 12 at the opening is in transition through the inclined surface 123, when the flange plate is installed, the bottom of the connection end of the spring 20 can be abutted to the inclined surface 123, and then the spring 20 is inserted into the insertion groove 12 through the inclined surface 123, and thus, the spring 20 is more convenient to install on the flange plate 10.

Furthermore, two flanges 10 are arranged, and two ends of the spring 20 are respectively clamped in the insertion grooves 12 of the two flanges 10. Meanwhile, the spring 20 can be locked when being connected with the insertion slot 12 so as to avoid easy falling off from the insertion slot 12.
