[0026] Embodiment 1

[0027] like Figures 1 to 3 As shown, one embodiment of the present application provides a lifting column, including a first column 400, a second column 500, an assembly part 100, a fixed mounting part 200 and an adjustable mounting part 300. The first column 400 is telescopically connected to the second column 500. The assembly part 100 is provided with a plurality of first mounting holes 110 and a plurality of second mounting holes 120. The first mounting holes 110 are used to cooperate with the fixed mounting part 200 to fix the assembly part 100 on the first column 400, and the second mounting holes 120 are used to cooperate with the adjustable mounting part 300 to adjust the gap size between the first column 400 and the second column 500.

[0028] During implementation, the first column 400 and the second column 500 are the main bodies of the lifting column, that is, the first column 400 can be telescopically movable relative to the second column 500, so as to adjust the overall length of the first column 400 and the second column 500.

[0029] The fixed installation member 200 cooperates with the first installation hole 110 on the assembly member 100 to fix the assembly member 100 to the first column 400. In some embodiments, the first column 400 is provided with a plurality of first screw holes, and the plurality of first screw holes correspond to the first installation holes 110 one by one. The fixed installation member 200 uses a first bolt, for example, the first installation hole 110 uses a screw hole, and the first bolt can be screwed into the first installation hole 110 and the first screw hole to achieve fixed installation of the assembly member 100 and the first column 400.

[0030] In other embodiments, the first mounting hole 110 can be a through hole. For example, the first mounting hole 110 is a Φ13 through hole, where Φ13 means that the diameter of the through hole is 13 mm, so that the first bolt passes through the first mounting hole 110 and is screwed into the first screw hole to achieve fixed installation of the assembly 100 and the first column 400.

[0031] The adjustable mounting member 300 cooperates with the second mounting hole 120 to adjust the size of the gap between the first column 400 and the second column 500. In some embodiments, the second mounting hole 120 is a second screw hole. For example, the second mounting hole 120 uses an M12 threaded hole, where M12 means that the maximum thread diameter of the threaded hole is 12. The adjustable mounting member 300 is a second bolt, which cooperates with the second screw hole. Since the assembly member 100 is fixedly connected to the first column 400, when the second bolt is screwed in and out of the second screw hole, the end of the second bolt can abut against the sliding cooperation portion of the first column 400 and the second column 500 to adjust the size of the gap between the first column 400 and the second column 500. Exemplarily, when the second bolt is screwed in, the second bolt contacts the first column 400 and applies a force from the first column 400 to the second column 500, so that the first column 400 is offset toward the second column 500 and is tightly connected with the second column 500, that is, the gap between the first column 400 and the second column 500 is reduced. At this time, the pressure between the first column 400 and the second column 500 increases, thereby increasing the friction between the first column 400 and the second column 500, and the positions of the first column 400 and the second column 500 are relatively fixed, ensuring the stability of the telescopic structure composed of the first column 400 and the second column 500. When the second bolt is unscrewed, the pressure applied by the second bolt to the first column 400 becomes smaller, so that the first column 400 returns to its original position. At this time, the gap between the first column 400 and the second column 500 becomes larger, and the friction between the first column 400 and the second column 500 becomes smaller or there is no friction, so the position of the first column 400 and the second column 500 can be adjusted to realize the telescopic function.

[0032] It should be noted that the first mounting hole 110 using a Φ13 through hole and the second mounting hole 120 using an M12 threaded hole are examples of an embodiment of the present application, and are not a specific limitation of the present application. In some other embodiments, the first mounting hole 110 and the second mounting hole 120 may also use other forms of holes, and related parameters such as the diameter of the hole may be set according to actual needs without limitation.

[0033] The lifting column of the present application includes a first column 400, a second column 500, an assembly part 100, a fixed mounting part 200 and an adjustable mounting part 300, wherein the assembly part 100 is provided with a plurality of first mounting holes 110 and a plurality of second mounting holes 120, the assembly part 100 is fixedly mounted on the first column 400 through the first mounting holes 110 in cooperation with the fixed mounting part 200, the first column 400 is used to cooperate with the second column 500 to be telescopically adjustable, and the second mounting holes 120 are used to cooperate with the adjustable mounting part 300 to adjust the gap between the first column 400 and the second column 500. When in use, by reducing the gap between the first column 400 and the second column 500, the connection between the first column 400 and the second column 500 is made more stable and reliable, thereby ensuring the stability of the lifting column.

[0034] In some optional embodiments, the assembly 100 includes a first assembly plate 130 and a second assembly plate 140 connected to the first assembly plate 130, the thickness of the first assembly plate 130 is greater than the thickness of the second assembly plate 140, and the first mounting hole 110 and the second mounting hole 120 are respectively arranged on the first mounting plate and the second mounting plate.

[0035] The assembly part 100 is composed of a first assembly plate 130 and a second assembly plate 140. The thickness of the first assembly plate 130 is greater than that of the second assembly plate 140, so that the first assembly plate 130 and the second assembly plate 140 form a step shape. The first mounting hole 110 is located on the first assembly plate 130, and the second mounting hole 120 is located on the second assembly plate 140, which facilitates corresponding assembly and improves assembly efficiency.

[0036] In some optional embodiments, taking the lifting column for an operating bed as an example, the lifting column is placed on the ground or installed on the bottom surface, and the operating bed is installed on the lifting column. The operating bed can be lifted and lowered by adjusting the relative positions of the first column 400 and the second column 500.

[0037] In some embodiments, the first column 400 has a slide rail 410 , and the second column 500 has a slide groove 510 that cooperates with the slide rail 410 .

[0039] In some optional embodiments, the first column 400 is equipped with assembly parts 100 on both sides opposite to each other, that is, the second column 500 is provided with a slide groove 510 on both sides opposite to each other, and correspondingly, the first column 400 is provided with two slide rails 410 corresponding to the slide grooves 510 on both sides. The assembly parts 100 on any side are used to adjust the gap between the slide rails 410 and the slide grooves 510 on the corresponding side to ensure the assembly stability of the first column 400 and the second column 500.

[0040] In some optional embodiments, a friction pad 600 is provided between the slide groove 510 and the slide rail 410. The friction pad 600 can effectively increase the friction between the slide groove 510 and the slide rail 410, so that the first column 400 and the second column 500 can be better telescopically adjusted.

[0041] In some optional embodiments, the first column 400 is provided with a guide column 420 , and the second column 500 is provided with a guide hole that cooperates with the guide column 420 .

[0042] In implementation, the guide post 420 is a long columnar structure, and the cross section of the guide post 420 can be circular, triangular, square, trapezoidal or other irregular shapes. Similarly, the guide hole can be a strip hole matching the guide post 420.
