Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a quick detachable motor rear end cap of preferred embodiment, including end cover body 1, shell 2, end cover body 1 and shell 2 are connected through the mode of pegging graft. A tapered slot 11 is provided at the inner wall of the right end portion of the housing 2, and a tapered insert 10 is provided at the inner wall of the left side of the cap body 1. When the end cover body 1 is inserted into the shell 2, the outer wall of the conical insert 10 is just attached to the inner wall of the conical slot 11.

The ring piece 5 is arranged on the outer sides of the end cover body 1 and the shell 2 together, and the ring piece 5 is arranged at the seam of the end cover body 1 and the shell 2.

A first snap ring 7 and a second snap ring 8 are integrally arranged on the inner wall of the ring piece 5, and a first ring groove 3 and a second ring groove 4 are respectively arranged on the motor shell 2 and the end cover body 1. After the motor shell 2 and the end cover body 1 are inserted, the first clamping ring 7 and the second clamping ring 8 are just inserted into the first annular groove 3 and the second annular groove 4.

The ring piece 5 is provided with a gap groove 6, the ring piece 5 has elasticity, and the ring piece 5 is elastically expanded through the gap groove 6, so that the ring piece 5 can be sleeved outside the motor shell 2 and the end cover body 1. The loop piece 5, by its own elasticity, prevents the first snap ring 7 and the second snap ring 8 from easily slipping out of the first loop and the second loop, thereby maintaining the interconnection between the end cap body 1 and the housing 2.

As shown in fig. 2, in order to further ensure the firmness of the ring piece 5 connecting the motor housing 2 and the end cover body 1, a quick-release part 9 is disposed at the position of the notch groove 6, the quick-release part 9 includes a first connecting block 91 and a second connecting block 92 respectively disposed on the ring piece 5, a screw rod 15 is jointly inserted into the first connecting block 91 and the second connecting block 92, two nuts are screwed on the screw rod 15 respectively, and the two nuts abut against the first connecting block 91 and the second connecting block 92. The expansion of the ring piece 5 is limited by the screw 15 and the nut, so that the fastening connection of the end cover body 1 and the shell 2 is realized.

The end cover body 1 and the shell 2 are connected in an inserting mode and can possibly rotate along the axis direction, in order to limit the mutual rotation of the end cover body 1 and the shell 2, a rotation limiting piece 12 is further arranged on the conical insertion piece 10, a rotation limiting groove 13 is further arranged on the conical insertion groove 11, after the end cover body 1 and the shell 2 are connected in an inserting mode, the rotation limiting piece 12 is just inserted into the rotation limiting groove 13, and the rotation between the end cover body 1 and the shell 2 is avoided through the mutual matching of the rotation limiting piece 12 and the rotation limiting groove 13.

As shown in fig. 3, the end cover body 1 is provided with an orientation groove 14 for the insertion of the shell 2, the orientation groove 14 is used for providing an installation direction for an installer, and since the orientation groove 14 is located on the outer surface of the end cover body 1 and the shell 2, the installer can install the end cover body 1 and the shell 2 conveniently by looking at the orientation groove 14 all the time, so that the installer can align and install the end cover body 1 and the shell 2 conveniently.

The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
