[0026] Specifically, such as Figure 1 As shown, a positioning screw 4 that passes through the side cover 3 is connected to the inner side of the telescopic cylinder housing 1. The positioning screw 4 passes through the side cover 3 and is connected to the inner side of the telescopic cylinder housing 1 to limit the position of the plug plate 2.

[0027] The inner side of the telescopic cylinder housing 1 is provided with a disassembly and maintenance component, which includes a plug groove 8, a rubber strip 11 is provided on the inner side of the plug groove 8, and a motor mounting compartment 7 is provided on one side of the plug groove 8. The disassembly and maintenance component is used for easy disassembly and maintenance of the telescopic cylinder.

[0028] Specifically, such as Figure 2 As shown, a planetary screw pair 6 is rotatably connected to the inner side of the telescopic cylinder housing 1. One end of the planetary screw pair 6 is connected to a connector 5. The internal motor drives the planetary screw pair 6 to transmit power, thereby driving the outer connector 5 to perform telescopic adjustment.

[0029] Specifically, such as Figure 2 As shown, the motor mounting compartment 7 is located inside the telescopic cylinder housing 1 on one side, providing a separate area for the motor mounting position and modularizing the parts. The insertion slot 8 is located inside the telescopic cylinder housing 1 at one end, and the insertion slot 8 is used for the snap-fit ​​positioning of the insertion plate 2.

[0030] Specifically, such as Figure 3 As shown, the rubber strip 11 is connected to both sides of the inside of the plug plate 2. Both sides of the inside of the plug plate 2 are provided with snap-fit ​​grooves 10 that are adapted to the rubber strip 11. The rubber strip 11 is snapped into the inside of the plug plate 2 by the limiting of the snap-fit ​​grooves 10, thereby improving the stability of the installation.

[0031] The inner side of the plug-in plate 2 is provided with a positioning adjustment component, which includes an adjustment box 13. The inner side of the adjustment box 13 is connected to a positioning block 15, and the outer side of the positioning block 15 is provided with a positioning hole 9. The positioning adjustment component is used for positioning adjustment when the plug-in plate 2 is installed.

[0032] Specifically, such as Figure 3 As shown, sliding plates 12 are slidably connected to both ends of the inner side of the plug-in plate 2. The adjustment box 13 is fixedly connected to one side of the sliding plate 12. The sliding plate 12 is slidably engaged with the inner side of the plug-in plate 2 to facilitate the positioning of the adjustment box 13.

When fixing the plug plate 2, a rubber strip 11 is set on the inner side for compression and limiting. After sliding to the installation position, the elastic connector 14 pushes the positioning block 15 into the positioning hole 9, which facilitates the pre-positioning of the plug plate 2 and improves the convenience of telescopic cylinder installation.

[0036] The specific solution is as follows: When disassembling and assembling the telescopic cylinder housing 1, remove the positioning screws 4 inside the side covers 3 on both sides, and then take out the side covers 3. At this time, the positioning block 15 can be squeezed at the outer opening to make the positioning block 15 disengage from the positioning hole 9. Then, the plug plate 2 can be taken out from the inside of the plug slot 8 to separate the telescopic cylinder housing 1 and the plug plate 2. Then, the inner side is installed through the modular division of the motor mounting compartment 7 and the plug slot 8, which facilitates the convenient access and maintenance of parts such as the motor or planetary screw pair 6, improving the convenience of maintenance. When fixing the plug plate 2, the inner side is provided with a rubber strip 11 for compression and limiting. After sliding to the installation position, the positioning block 15 is pushed into the inside of the positioning hole 9 by the elastic force of the elastic connector 14. Then, the side cover 3 is snapped on to limit and fix the plug plate 2 and the adjustment box 13. Then, the positioning screws 4 are tightened to fix it.
