DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1: A height-adjustable switch trolley support, see Figure 1-Figure 4As shown, it includes a housing 1, a motor 2, a bevel gear I3, a bevel gear II4, a rotating wheel 401, a screw 5, a lifting sleeve 6, a table 7, a telescopic guide rod 8, a universal wheel 20 and a handle 21. The motor 2 is connected to the inside of the housing 1 by bolts, and the output shaft of the motor 2 is connected to the bevel gear I3 by welding. The housing 1 is rotatably connected to the bevel gear II4, and the bevel gear I3 is meshed with the bevel gear II4. The bevel gear II4 is connected to the rotating wheel 401 by welding. The rotating wheel 401 is rotatably connected to the housing 1, and the screw 5 is connected to the bevel gear II4 by welding. The lifting sleeve 6 is threadedly connected to the screw 5, and the lifting sleeve 6 is connected to the table 7 by welding. The table 7 is used to place the switch trolley, and a telescopic guide rod 8 is connected between the table 7 and the housing 1. The telescopic guide rod 8 is used to guide the table 7. At least three universal wheels 20 are rotatably connected to the housing 1, and the universal wheels 20 are used to assist in moving the housing 1. The housing 1 is connected to a handle 21 by bolts. The hand 21 is provided with an anti-slip cover, and also includes a support rod 801, a rack I9, a full gear 10, a missing gear 11, a rack II 12, an extension plate 14, a guide rail 701 and an auxiliary wheel set 13. The support rods 801 distributed on the left and right are connected to the inside of the housing 1 by welding, and the rack I9 distributed on the left and right is connected to the lifting sleeve 6 by welding. The upper end of the support rod 801 is rotatably connected to the full gear 10, and the full gear 10 is meshed with the rack I9. The full gear 10 is connected to the full gear 10 by welding. There is a missing gear 11, and the table 7 is slidably connected to the left and right extended plates 14. The extension plate 14 is connected to the rack II 12 by welding. The missing gear 11 is meshed with the rack II 12. The table 7 is connected to the guide rail 701 by welding. At least five auxiliary wheel groups 13 are rotatably connected inside the guide rail 701. The rack II 12 is in contact with the auxiliary wheel group 13. By turning on the motor 2, the full gear 10 drives the missing gear 11 to rotate, and the rack II 12 drives the extension plate 14 to move outward.

[0026] When the switch trolley needs to be inspected, the staff holds the handle 21 by hand and moves the shell 1 to a suitable location. The universal wheel 20 rotates to reduce the friction between the shell 1 and the ground, making it easier for the staff to move the shell 1. Then the staff turns on the motor 2, and the output shaft of the motor 2 rotates to drive the bevel gear I3 to rotate and engage with the bevel gear II4, so that the bevel gear II4 drives the screw 5 to rotate, and then the lifting sleeve 6 drives the table 7 to move upward, so as to achieve the effect of adjusting the height of the table 7, the lifting sleeve 6 drives the rack I9 to move upward and engage with the full gear 10, so that the full gear 10 drives the missing gear 11 to rotate and engage with the rack II12, and then the rack II12 drives the extension plate 14 to move outward, and the auxiliary wheel group 13 rotates to make the rack II12 move smoothly. When the extension plate 14 moves outward to a suitable position, the staff turns off the motor 2, so as to achieve the purpose of extending the volume occupied by the table 7, which is convenient for placing switch trolleys of different sizes.

[0027] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes a suction cup 15, a hose 17, an airbag 18, a plug 19, and a spring 16. The outer shell 1 is connected to the hose 17 which is symmetrically distributed. The suction cups 15 which are distributed up and down are slidably connected to the hose 17. The outer shell 1 is connected to the airbag 18, which is made of polyphthalamide fabric. The plug 19 is threadedly connected to the airbag 18. The suction cup 15 is sleeved with a spring 16, and both ends of the spring 16 are respectively connected to the outer shell 1 and the suction cup 15. The spring 16 is used for buffering. By squeezing the airbag 18, the gas enters the suction cup 15 through the hose 17, squeezing the suction cup 15 to move backward.

[0028] When moving the housing 1 to a suitable location, the staff squeezes the airbag 18 by hand, so that the gas in the airbag 18 enters the suction cup 15 through the hose 17, and then squeezes the suction cup 15 to move backward and adsorb on the wall. The spring 16 is stretched accordingly, slowing down the moving speed of the suction cup 15, so that the suction cup 15 can be stably adsorbed on the wall, thereby achieving the purpose of fixing the housing 1 and preventing the housing 1 from moving when the switch trolley is placed.

[0029] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
