Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1, the utility model discloses a plastic envelope direct current motor with novel rear end cap 2, including motor body 1, motor body 1 includes rear end cap 2. In order to reduce the possibility that dust enters the interior of the motor body 1 from some radiating holes on the rear section cover. A dust guard 3 is placed inside the rear end cap 2 (see fig. 4). The dust guard 3 is matched with the inner space shape of the rear end cover 2.

Referring to fig. 4, the dust-proof plate 3 is attached and detached for the convenience of an operator. Four clamping components 4 are uniformly arranged on the rear end cover 2 in a penetrating way. Four clamping components 4 are evenly distributed on the peripheral surface of the rear end cover 2. Four placing grooves 11 are evenly formed in the inner peripheral wall of the rear end cover 2, and the clamping assembly 4 is placed inside the placing grooves 11.

Referring to fig. 4, the clamping assembly 4 includes a grip 41, a threaded hole 111, and a push rod 112. The screw hole 111 is provided on the inner side of the mounting slot 11, and the inside of the screw hole 111 communicates with the inside of the mounting slot 11. The push rod 112 is located inside the threaded hole 111, and the screw is in threaded connection with the threaded hole 111. The push rod 112 pushes the hand grip 41 to move, and all four hand grips 41 are opposite to the central axis of the rear end cover 2.

Referring to fig. 4, the handle 41 includes two horizontal plates 411 and a vertical plate 412, and two ends of the vertical plate 412 are respectively fixed to the two horizontal plates 411. The sides of the two transverse plates 411 far away from the vertical plate 412 are attached to the two sides of the inner wall of the placing groove, and one side of the vertical plate 412 faces the threaded hole 111, that is, one side of the vertical plate 412 faces the push rod 112. In order to prolong the service life of the riser 412, a rubber protective layer 5 is adhered to one side of the riser 412 close to the threaded hole 111 by glue. One end surfaces of the two transverse plates 411 are flush with one side surfaces of the vertical plates 412 close to the threaded holes 111, and the two transverse plates 411 are arranged along the central axis direction of the rear end cover 2. When the dust-proof plate 3 is placed inside the rear end cover 2, the two cross plates 411 are parallel to the dust-proof plate 3. And the height of the dust-proof plate 3 is less than the distance between the two transverse plates 411.

Referring to fig. 4, it is particularly noted that when the hand 41 is completely located inside the placing slot 11, the edges of the two transverse plates 411 on the side away from the vertical plate 412 are the same as the edge shape of the placing slot 11.

Referring to fig. 4, the dust-proof plate 3 is fixed at a time for the operator to easily perform. Four positioning rods 7 are fixed on the top of the inner wall of the rear end cover 2. The plane of one end of the positioning rod 7, which is not fixed to the rear end cover 2, is flush with the surface of one side, close to the vertical plate 412, of the transverse plate 411, which is close to one side of the inner wall of the rear end cover 2. When one side of dust guard 3 touched locating lever 7, operating personnel rotated push rod 112 in screw hole 111 this moment, and push rod 112 drove riser 412 and moved, and riser 412 drove two diaphragm 411 motions, and two diaphragm 411 move to the outside of dust guard 3, and diaphragm 411 and dust guard 3 laminate mutually. The position of the dust-proof plate 3 inside the rear cover 2 is fixed.

Referring to fig. 4, in order to expand the range of use of the device. The relative one side of two diaphragm 411 all articulates there is the backup pad, is fixed with spring 61 between backup pad and the relative diaphragm 411. The two ends of the spring 61 are fixed to the supporting plate and the transverse plate 411. When the spring 61 is in a natural state, the support plate is in an inclined state. With the thickness of the dust-proof plate 3 varying, the spring 61 deforms, changing the distance between the two cross plates 411. At the same time, the two supporting plates clamp the dust-proof plate 3 due to the elastic restoring force of the spring 61. Specifically, the width of the support plate is smaller than that of the cross plate 411, and the support plate does not contact the vertical plate 412 when the support plate rotates around the end of the support plate hinged to the cross plate 411.

Referring to fig. 4, in order to limit the moving distance of the grasping hand 41 and avoid the grasping hand 41 from coming out of contact with the standing groove 11. A first sliding groove 113 is formed in the inner wall of the placing groove 11 on the side close to the opening of the rear end cover 2, and the first sliding groove 113 is formed along the width direction of the horizontal plate 411. One side of one of the horizontal plates 411 away from the vertical plate 412 is fixed with a sliding block 114, the sliding block 114 is located inside the first sliding groove 113, and the sliding block 114 is connected with the first sliding groove 113 in a sliding manner. A guide rod 115 is fixed between two opposite sides of the inner wall of the first sliding chute 113, the linear direction of the guide rod 115 is the same as the direction of the first sliding chute 113, and the guide rod 115 passes through the sliding block 114.

Example (b):

when the dust-proof plate 3 is fixed inside the rear end cover 2. At first place dust guard 3 inside rear end cap 2, touch locating lever 7 when dust guard 3 bumps, and dust guard 3 can't be when continuing the motion towards the inside depths of rear end cap 2. The operator rotates the push rod 112 at this time, the push rod 112 rotates inside the threaded hole 111, and the push rod 112 touches the vertical plate 412 after moving inside the threaded hole 111. The operator continues to rotate the push rod 112, the push rod 112 pushes the vertical plate 412 to move, and the vertical plate 412 drives the two cross plates 411 to move.

Due to the positioning effect of the positioning rod 7, the two transverse plates 411 of the same gripper 41 are both located on two sides of the dust guard 3. When the dust-proof plate 3 partially enters the inside of the gripper 41, the supporting plate is driven to move due to the different thickness of the dust-proof plate 3, and the supporting plate drives the spring 61 to deform.

When the operator cannot continuously screw the push rod 112, i.e. the vertical plate 412 contacts with part of the outer peripheral surface of the dust-proof plate 3, the push rod 112 is completely located inside the threaded hole 111.

When the operator needs to disassemble and replace the dust-proof plate 3, the operator rotates the push rod 112 in the direction to make the push rod 112 completely separated from the threaded hole 111.

At this time, the operator pushes the hand grip 41 in the rear end cap 2 in the reverse direction, so that the dust-proof plate 3 can be taken out from the rear end cap 2 when the hand grip 41 is completely located inside the placement groove 11.

Therefore, the method comprises the following steps: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
