The slide bar 92 can limit the box cover 7 inside the control box 6 to complete the installation of the box cover 7. The inner wall of the control box 6 is provided with an inclined groove 95, and the limiting groove 94 is connected to the inclined groove 95. The inner wall of the inclined groove 95 is fixedly installed with an inclined surface block 96. The bottom of the inclined surface block 96 is flush with the inner wall of the inclined groove 95, and the top of the inclined surface block 96 is flush with the inner wall of the control box 6. The box cover 7 is further pushed into the inside of the control box 6 by using the handle 8. At the same time, the slide bar 92 and the slider 97 can drive the latch 93 to slide from the inside of the limiting groove 94 into the inside of the inclined groove 95, and slide through the inclined groove 95 to the inclined surface of the inclined surface block 96. The inclined surface of the inclined surface block 96 can be used to make the latch 93 slide into the inside of the control box 6 , thereby breaking away from the limit position of the limit groove 94, the slide bar 92 is fixedly mounted on the inner wall of the box cover 7, and the outer wall of the slide bar 92 is slidably connected with a slide block 97, and the outer wall of the slide bar 92 is sleeved with a return spring 98, one end of the return spring 98 is fixedly mounted on the side wall of the slide block 97, and the other end of the return spring 98 is fixedly mounted on the inner wall of the box cover 7. The slide block 97 can be pulled to return to its original position through the elasticity of the return spring 98, so that the slide block 97 can drive the latch 93 to move from the guide groove 91 to the inside of the limit groove 94. When the box cover 7 moves toward the inside of the control box 6, the latch 93 will squeeze the slide block 97 under the guiding effect of the guide groove 91, so that the slide block 97 continues to slide on the outer wall of the slide bar 92 and stretch the return spring Spring 98, the latch 93 is slidably connected to the inner wall of the slider 97, and the latch 93 passes through the slider 97, the bottom of the latch 93 is attached to the inner wall of the limit groove 94, the box cover 7 is aligned with the interior of the control box 6, and pushed toward the interior of the control box 6, at this time, the box cover 7 will drive the slide bar 92 and the slider 97 to move synchronously toward the interior of the control box 6, at this time, the slider 97 will drive the latch 93 to fit the inner wall of the guide groove 91 and move toward the interior of the control box 6, the top of the latch 93 is fixedly installed with a limit block 99, the outer wall of the latch 93 is sleeved with a limit spring 910, one end of the limit spring 910 is fixedly installed on the top of the slider 97, and the other end of the limit spring 910 is fixedly installed on the lower surface of the limit block 99.

[0029] The auxiliary mechanism 10 comprises a limit rod 101, a baffle 102 and an auxiliary spring 103; the limit rod 101 is slidably connected to the inner wall of the box cover 7, and the limit rod 101 passes through the box cover 7, and the outer wall of the limit rod 101 is in contact with the top of the limit block 99. The limit rod 101 can be used to limit the height of the latch 93 to prevent the box cover 7 from being hit and driving the latch 93 to slide out of the limit groove 94 through the inclined groove 95 and the inclined surface block 96, thereby improving the stability of the latch 93. The left side of the limit rod 101 is fixedly installed. There is a baffle 102, and the outer wall of the limit rod 101 is sleeved with an auxiliary spring 103. One end of the auxiliary spring 103 is fixedly installed on the side wall of the baffle 102, and the other end of the auxiliary spring 103 is fixedly installed on the outer wall of the box cover 7. The limit rod 101 is pulled by the baffle 102, and the auxiliary spring 103 is stretched at the same time, so that the baffle 102 drives the limit rod 101 to slide toward the outside of the control box 6, and the limit rod 101 is separated from the top of the limit block 99, so that the limit rod 101 is separated from the limit on the latch 93.

[0030] Working principle: when the box cover 7 and the control box 6 need to be installed together, the box cover 7 is aligned with the inside of the control box 6 and pushed into the inside of the control box 6. At this time, the box cover 7 will drive the slide bar 92 and the slider 97 to move synchronously into the inside of the control box 6. At this time, the slider 97 will drive the latch 93 to fit the inner wall of the guide groove 91 and move into the inside of the control box 6. At this time, under the guiding effect of the guide groove 91, the latch 93 will squeeze the slider 97, so that the slider 97 continues to slide on the outer wall of the slide bar 92 and stretch the reset spring 98. When the latch 93 moves to the limit groove 94 on the inner wall of the guide groove 91, the latch 93 will be out of the guide of the guide groove 91, and the return spring 98 will be stretched. The elasticity of the return spring 98 can pull the slider 97 to return to its original position, so that the slider 97 can drive the latch 93 to move from the guide groove 91 to the inside of the limit groove 94. At this time, the limit groove 94 is used to cooperate with the latch 93, the slider 97, and the slide bar 92 to limit the box cover 7 inside the control box 6, and the installation of the box cover 7 can be completed. When the box cover 7 needs to be removed, the limit rod 101 is first pulled through the baffle 102, and the auxiliary spring 103 is stretched at the same time, so that the baffle 102 drives the limit rod 101 to slide toward the outside of the control box 6, and the limit rod 101 is separated from the top of the limit block 99. At this time, the handle 8 is used to continue to move the box cover 7 to the control box 6. The inner part of the control box 6 is pushed forward, and at the same time, the slide bar 92 and the slider 97 can drive the latch 93 to slide from the inside of the limit groove 94 into the inside of the inclined groove 95, and slide to the inclined surface of the inclined block 96 through the inclined groove 95. At this time, the latch 93 will be squeezed by the inclined surface of the inclined block 96, so that the latch 93 slides upward on the inner wall of the slider 97. At the same time, the limit block 99 can stretch the limit spring 910, and the latch 93 can slide into the interior of the control box 6 through the inclined surface of the inclined block 96, so that the latch 93 is out of the limit of the limit groove 94. When the latch 93 slides into the inner wall of the control box 6 through the inclined block 96, the elasticity of the reset spring 98 can be By pulling the slider 97, the slider 97 slides and resets on the outer wall of the slide rod 92. At the same time, the slider 97 will drive the latch 93 to move to the end away from the limit groove 94 and the inclined groove 95, so that the box cover 7 is separated from the limit of the latch 93 and the limit groove 94. At this time, the box cover 7 can be pulled toward the outside of the control box 6 to separate the box cover 7 from the control box 6, and the control box 6 can be opened. Through the above operation, the box cover 7 can be installed with the control box 6 by pushing it once. Pushing the box cover 7 again can separate the box cover 7 from the control box 6, making the disassembly and assembly of the box cover 7 and the control box 6 easier, and convenient for the staff to repair the drive assembly inside the control box 6.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
