One side of the mounting plate 10 is provided with a connection assembly 6;

[0030] A column body 3 movably penetrates through one side of the first cover plate 2. An LED light strip 4 is installed on the outer side of the top of the column body 3. The connection of the LED light strip 4 also provides lighting for use at night or in low-light environments, further enhancing the safety of use. A second cover plate 5 is installed on the top of the column body 3 and located above the LED light strip 4. The center of the top of the bottom plate 12 is fixedly provided with a hydraulic cylinder 14. The push rod end of the hydraulic cylinder 14 is fixedly provided with a connecting plate 20 fixed to the inner side wall of the column body 3.

[0031] Limit blocks 11 and sliding rods 15 are respectively fixedly provided on the top of the bottom plate 12. The number of the limit blocks 11 and the sliding rods 15 is four. A sliding plate 21 is slidably connected to the outer side of the sliding rods 15. The top of the sliding plate 21 is fixedly provided at the bottom of the column body 3. A plurality of adjusting rods 19 are threadedly connected to the outer side of the sliding plate 21. The bottom of the adjusting rod 19 is a screw rod, and the screw rod is threadedly connected to the sliding plate 21. The top of the screw rod is an anti-collision block. The material of the anti-collision block can be rubber or metal. Rotate the adjusting rod 19 so that the screw rod is threadedly connected to the sliding plate 21, so that the anti-collision block is at different heights on the top of the sliding plate 21. At this time, the distance between the sliding plate 21 and the cross plate 17 can be adjusted.

[0032] A sleeve 18 is fixedly provided at the bottom of the first cover plate 2. The material of the sleeve 18 is nylon. The sleeve 18 is used to assist the lifting and sliding of the column body 3. A cross plate 17 is fixedly provided at the bottom of the sleeve 18. One side of the column body 3 sequentially movably penetrates through the cross plate 17 and one side of the sleeve 18. One end of the top of the sliding rod 15 is fixedly provided on one side of the cross plate 17.

[0033] On one side of the top of the box body 1, a wire pipe 7 for the passage of wires is fixed. On one side of the bottom of the box body 1, a drain pipe 8 is fixed. Connecting the drain pipe 8 to the sewer can ensure that the accumulated water or other liquids generated during the use of the lifting column can be smoothly discharged, avoiding water accumulation inside the box body 1.

[0034] To facilitate the replacement of the motor 9, a connection component 6 is provided. The connection component 6 includes a fixing frame 61. A limiting groove 62 is formed on one side of the fixing frame 61. Inside the limiting groove 62, a connection frame 63 fixed to the bottom of the motor 9 is inserted. Inside the limiting groove 62, a sliding groove 64 is provided. On one side of the connection frame 63, two locking grooves are formed. Inside the locking grooves, a locking rod 65 is inserted. One end of the locking rod 65 is fixed with a pulling plate 67. A tension spring 66 is sleeved on the outer side of the locking rod 65. Pull the pulling plate 67 to one side. At this time, the pulling plate 67 drives the locking rod 65 to move to one side. At this time, the pulling plate 67 stretches the tension spring 66, and at the same time, the locking rod 65 leaves the inside of the locking groove. Then, take out the motor 9 upward to maintain it. The two ends of the tension spring 66 are respectively connected to one side of the fixing frame 61 and the pulling plate 67. One side of the top of the fixing frame 61 is fixed to one side of the bottom of the mounting plate 10. Insert the connection frame 63 at the bottom of the motor 9 inside the limiting groove 62. Then, release the pulling force on the pulling plate 67. Under the pulling force of the tension spring 66, the locking rod 65 is inserted into the inside of the locking groove, and the locking rod 65 is inserted into the sliding groove 64. At this time, the installation of the motor 9 is completed.

[0035] Working principle: When installing the lifting column, first dig a hole in the ground. Since the height of the box body 1 is not greater than 815 mm, the depth of the dug hole is greatly reduced during installation. Place the box body 1 into the dug hole, pass the wire through the wire pipe 7 and connect it to the internal motor 9 and the LED light strip 4, and connect the drain pipe 8 to the sewer through a pipe. Then, connect the first cover plate 2 to the top of the box body 1 with bolts;

[0036] When it is necessary to raise the column body 3, only need to control the rotation of the output shaft of the motor 9. The output shaft drives the input shaft of the oil pump to rotate, so that the oil pump inputs hydraulic oil into the oil inlet end of the hydraulic cylinder 14. At this time, the push rod end of the hydraulic cylinder 14 extends, and the push rod end pushes the column body 3 to extend upward from the top of the first cover plate 2. At the same time, the sliding plate 21 is slidably sleeved on the outer sides of a plurality of sliding rods 15. At the same time, when the column body 3 moves upward, the LED light strip 4 generates a light prompt;

[0037] When the motor 9 needs to be removed for maintenance after long-term operation, only need to pull the pulling plate 67 to one side. At this time, the pulling plate 67 drives the locking rod 65 to move to one side. At this time, the pulling plate 67 stretches the tension spring 66, and at the same time, the locking rod 65 leaves the inside of the locking groove. Then, take out the motor 9 upward to maintain it;

[0038] After the maintenance of the motor 9, first pull the pull plate 67 to one side so that the locking rod 65 leaves the inner side of the limit groove 62, then insert the connecting frame 63 at the bottom of the motor 9 into the inner side of the limit groove 62, and then release the pulling force on the pull plate 67. Under the pulling force of the tension spring 66, the locking rod 65 is inserted into the inner side of the locking groove and the locking rod 65 is inserted into the inner side of the sliding groove 64. At this time, the installation of the motor 9 is completed.

[0039] In summary, the height of the box body 1 is designed to be relatively compact. The height of the box body 1 is not greater than 815 mm, which greatly reduces the depth of the pit that needs to be dug during the installation process, reduces the excavation difficulty, reduces the excavation time, and also saves material and labor costs. The wires are connected through the wire pipes 7, effectively avoiding the exposure and aging of the wires, improving the safety of the equipment. The access of the LED light strip 4 also provides lighting for use at night or in low-light environments, further enhancing the safety of use. Connecting the drain pipe 8 to the sewer can ensure that the accumulated water or other liquids generated during the use of the lifting column can be smoothly discharged, avoiding water accumulation inside the box body 1;

[0040] When the motor 9 needs to be maintained, simply pull the pull plate 67 to one side to unlock the motor 9, so that it can be easily removed from the installation position. During the installation of the motor 9, the locking rod 65 is automatically inserted into the locking groove and the sliding groove 64 under the pulling force of the tension spring 66, ensuring the stability of the motor 9 after installation.
