[0028] Anti-loosening component 2, installed on mounting part 1: There are two anti-loosening components 2, each including a locking block 201, a protrusion 202, a locking groove 203, and a spring 204. The locking groove 203 is located inside the mounting part 1 and the rotating part 6. The spring 204 is located on one side of the inside of the locking groove 203 near the inside of the mounting part 1, and the locking block 201 is located on the other side of the spring 204. The side of the locking block 201 away from the spring 204 penetrates the outer wall of the mounting part 1. The top of the locking block 201 is provided with a protrusion 202, which is located away from the spring. One side of the spring 204 penetrates the outer wall of the rotating part 6. When the sealing sleeve is not in use, the spring 204 extends and the locking block 201 protrudes from the surface of the mounting part 1. When the sealing sleeve is installed, the rotating part 6 is clamped by the clamping protrusion 202, so that the locking block 201 is fully inserted into the slot 203. The rotating sealing sleeve is installed inside the mounting hole of the motor housing through the thread of the mounting part 1. Then the clamping of the rotating part 6 is released, the spring 204 extends, so that the locking block 201 presses against the two sides inside the mounting hole of the motor housing, which helps to fix the sealing sleeve in place.
[0029] Second Embodiment
[0030] As attached Figure 1 AppendixFigure 2 and attached Figure 4 The inflatable layer 7 is arranged on the inner wall of the sealing sleeve body 8. The inflatable layer 7 is annular with a hollow interior. The material of the inflatable layer 7 is elastic polyurethane. The size of the inflatable layer 7 is suitable for the size of the sealing sleeve body 8. The inflatable layer 7 is inflated by the air bag 5. The air outlet 9 controls the air in the inflatable layer 7.
[0031] The air bag 5 is arranged on the side wall of the sealing sleeve body 8. The air bag 5 penetrates the side wall of the sealing sleeve body 8 and is connected to the interior of the inflatable layer 7. The air bag 5 is provided with a check valve and a one-way valve. The other side wall of the sealing sleeve body 8 is provided with an air outlet 9. The air outlet 9 is connected to the interior of the inflatable layer 7 on one side of the sealing sleeve body 8. The inflatable layer 7 is inflated and expanded to fill the space in the sealing sleeve by operating the air bag 5. The phase line is filled and protected. The motor phase line port is sealed to prevent moisture and dust from entering the motor.
[0032] The mounting member 1 and the outer side wall of the sealing sleeve body 8 are provided with threads. The mounting member 1 and the sealing sleeve body 8 are hollow. The sealing sleeve is installed in the mounting hole of the motor shell through the threads of the mounting member 1.
[0033] The number of inclined pieces 4 is multiple. The inclined pieces 4 are arranged in a circular array. The top of the inclined piece 4 is thin and the bottom is thick. During the continuous tightening of the cap 3 on the sealing sleeve body 8, the inclined pieces 4 will converge and press in the middle, thereby fixing and protecting the internal phase line.
[0034] The cap 3 is movably connected to the sealing sleeve body 8 through the inner side wall threads. The size of the cap 3 is suitable for the size of the inclined piece 4. The cap 3 is rotated on the sealing sleeve body 8 to control the fixation and protection of the internal phase line or to loosen and take out.
[0035] The shape of the rotating member 6 is hexagonal. The size of the rotating member 6 is larger than the size of the sealing sleeve body 8. The rotating member 6 controls the installation of the sealing sleeve in the mounting hole of the motor shell.
[0036] Working principle: when the sealing sleeve is not used, the spring 204 extends the clamping block 201 to extend out of the surface of the mounting member 1. When the sealing sleeve is installed, the clamping block 201 is clamped and rotated by the clamping protrusion 202, so that the clamping block 201 completely enters the clamping groove 203. The sealing sleeve is installed in the mounting hole of the motor shell through the threaded mounting member 1, and then the clamping of the rotating member 6 is released. The spring 204 is stretched, so that the clamping block 201 is pressed on both sides of the inside of the motor shell mounting hole, helping the sealing sleeve to be installed and fixed. In the long-term shaking working environment, the installation connection is not easy to loosen. Before the sealing sleeve is installed, the phase line is first passed through the inside of the sealing sleeve. The inflation layer 7 is inflated and expanded to fill the space inside the sealing sleeve, and the phase line is filled and protected. The phase line port of the motor is sealed to prevent water and dust from entering the inside of the motor. The air in the inflation layer 7 is discharged by opening the air outlet 9 switch, and the phase line can be normally taken out.
