Description of the embodiments

The following detailed description of the utility model is provided in connection with the accompanying drawings to facilitate understanding and grasping of the technical scheme of the utility model.

Referring to fig. 1, a motor end cover fixing connection structure includes a housing 1 and an end cover 2 provided at an end of the housing 1. The end cover 2 is provided with fastener 3 towards one side of casing 1, is provided with spacing groove 11 on the tip periphery wall of casing 1. The fastener 3 is used to connect the housing 1 and the end cap 2 together.

Referring to fig. 2, the fastener 3 includes a fixing ring 31, a connection block 32, and a fastening open loop 33. One end of the connecting block 32 is connected with the fixed ring 31, and the other end of the connecting block 32 is connected with the fastening open ring 33; the fixed ring 31 is sleeved on the outer peripheral wall of the end cover 2 and is fixedly connected with the outer wall of the end cover 2 by welding; an opening 35 is arranged on one side of the fastening ring 33, connecting plates 34 are arranged at two ends of the opening 35, and through holes 341 are arranged on the connecting plates 34. The radius of the fastening ring 33 can be controlled by enlarging or reducing the size of the opening 35. Through holes 341 formed in the connecting plate 34 are convenient for the bolts to screw the fastening ring 33 on the shell 1 so as to connect the end cover 2 with the shell 1, meanwhile, only one connecting point is arranged, and the connection of the shell 1 and the end cover 2 by the fastener 3 can be realized by only one bolt, so that the operation is simple and convenient, and the disassembly and the maintenance are more convenient and quicker. In order to prevent the fastening ring 33 from sliding up and down on the housing 1, a limit groove 11 is arranged on the periphery of the end part of the housing 1; and the limiting groove 11 is longitudinally provided with a plurality of anti-slip raised strips 111 at intervals along the peripheral wall. The anti-slip ribs 111 can increase friction between the limit groove 11 and the fastening ring 33, thereby preventing the relative rotation of the end cover 2 and the housing 1.

Referring to fig. 3 and 4, in order to make the connection between the end cap 2 and the housing 1 more stable, a clamping ring 21 is provided on a side of the end cap 2 facing the housing 1, and a radius of an end of the clamping ring 21 near the housing 1 is smaller than a radius of an end of the clamping ring 21 far from the housing 1; while the radius of the port of the housing 1 is larger than the radius of the housing 1 away from the port. The conical surface of the clamping ring 21 is matched with the conical surface of the inner wall of the port of the shell 1. In order to make the connection of the grommet 21 with the inner wall of the port of the case 1 more stable, an annular rubber ring 211 is provided on the outer peripheral wall of the grommet 21. The clamping table ring 21 is in interference fit with the port of the shell 1, so that connection between the port and the shell 1 can be better consolidated, and the tightness between the port and the shell 1 can be improved.
