[0029] Embodiment 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 The present embodiment provides a lifting column device 100, which includes a lifting column assembly 10, a shield assembly 20 and at least one support member 30. The shield assembly 20 is arranged around the lifting column assembly 10. The lifting column assembly 10 can move along the vertical direction to drive the shield assembly 20 to move along the vertical direction. The support member 30 is fixedly connected to the lifting column assembly 10. The support member 30 is formed with a guide groove 31. The inner surface of the shield assembly 20 is formed with a guide plate 26 for matching with the guide groove 31. The guide plate 26 is at least partially inserted in the guide groove 31, so that the shield assembly 20 can be detachably connected to the support member 30.

[0031] In this embodiment, the lifting column device 100 is applied to the operating bed 200. When the table 201 of the operating bed 200 is raised to a high position, the shield assembly 20 can protect the lifting column assembly 10 of the operating bed 200. The lifting column device 100 can support the table 201 to achieve the lifting and lowering adjustment of the table 201. The lifting column device 100 is a common mechanical structure of a modern operating bed 200, and is widely used in multi-position electric lifting operating beds.

[0032] In this embodiment, when the operating bed 200 is raised to a high position, the lifting column assembly 10 can be raised in the vertical direction to raise the part of the table 201 of the operating bed 200 to the required height. The outer shield assembly 20 is arranged around the lifting column assembly 10. After the third-level column 13 rises to a certain height, the guide plate 26 in the shield assembly 20 and the guide groove 31 on the support member 30 are inserted and limited to each other, driving the shield assembly 20 to move in the vertical direction. When the lifting column assembly 10 is in the extreme state of full expansion, the shield assembly 20 is also in the extreme state of full expansion, and at this time, the shield assembly 20 can cover the lifting column assembly 10 to prevent the lifting column assembly 10 from being exposed.

[0033] Specifically, the shield assembly 20 can be a multi-fold structure formed by nesting multiple levels of cover shells, and the shield assembly 20 can be driven to gradually unfold during the process of the three-level column 13 rising in height. At the same time, in this embodiment, the connection method between different levels of cover shells is not limited to meet different needs. For example, different levels of cover shells can be connected to each other through arc hooks and limit buckles. As the uppermost cover shell moves vertically to a certain height, the cover shell can drive the lower-level cover shells to move in the vertical direction in turn.

[0034] In this embodiment, by fixing the guide plate 26 on the inner side of the shield assembly 20, the guide plate 26 can correspond to the guide groove 31 on the support member 30 fixed to the outermost lifting column device 100. After the guide plate 26 is connected to the guide groove 31, multi-degree-of-freedom limiting can be achieved.

[0035] In addition, in this embodiment, the lifting column assembly 10 can be raised to the limit position, that is, the top of the lifting column assembly 10 is raised to the highest position, and the shield assembly 20 is also in a fully extended protection state. In some embodiments, when the lifting column assembly 10 is raised to the limit position, the shield assembly 20 still has a margin in the vertical direction, so that the lifting column assembly 10 can be fully protected no matter how it changes, and the shield assembly 20 can also play a full protective role.

[0036] Embodiment 2

[0037] Reference Figure 3 and Figure 4 On the basis of the above-mentioned first embodiment, the second embodiment of the utility model provides a lifting column device 100, wherein the support member 30 includes a fixed portion 32 and an extending portion 33, the fixed portion 32 is fixedly connected to the outer surface of the lifting column assembly 10, the extending portion 33 extends from the fixed portion 32 along the horizontal direction, and the guide groove 31 is provided at one end of the extending portion 33 away from the fixed portion 32.

[0038] In this embodiment, the fixing portion 32 and the extending portion 33 can be perpendicular to each other, so that when the fixing portion 32 is attached to the outer surface of the lifting column assembly 10, the extending portion 33 extends horizontally from the fixing portion 32. The guide groove 31 is provided at the end of the extending portion 33 farthest from the fixing portion 32, and the guide groove 31 is in the shape of an elongated groove. The outermost portion of the guide groove 31 can be chamfered to avoid interference with the guide plate 26 when in contact, and to facilitate the insertion of the guide plate 26 into the guide groove 31.

[0039] Specifically, the depth of the guide groove 31 has a certain depth, and the depth of the guide groove 31 is longer than the insertion depth of the guide plate 26. In this way, it can be ensured that the guide plate 26 is inserted into the guide groove 31 accordingly, and the depth of the guide groove 31 is a guarantee for limiting the freedom of the shield assembly 20. If the depth of the guide groove 31 is insufficient, the rotational freedom of the shield assembly 20 along the Z axis cannot be limited, so a reasonable setting of the depth can improve the connection stability of the shield assembly 20.

[0040] Embodiment 3

[0041] Reference Figure 3 and Figure 4 On the basis of the above-mentioned second embodiment, the third embodiment of the utility model provides a lifting column device 100, wherein the fixing portion 32 and the extending portion 33 are both sheet metal parts, the fixing portion 32 and the extending portion 33 are arranged at a right angle, the fixing portion 32 is attached to the outer surface of the lifting column assembly 10, and the guide groove 31 and the guide plate 26 are both arranged along the vertical direction.

[0042] In this embodiment, the fixing part 32 and the extension part 33 as components of the support member 30 are both made by bending a sheet metal part. The manufacturing process is simple, the manufacturing cost is low, and the overall precision requirement is relatively low, which greatly reduces the cost of use. The sheet metal part is thin and has good rigidity, which not only ensures that the weight is not too heavy, is easy to disassemble and clean and maintain, but also ensures that the support member 30 has good strength and a longer service life.

[0043] In addition, in the present embodiment, the guide groove 31 and the guide plate 26 are arranged along the same direction and in the same direction as the movement direction of the lifting column assembly 10, that is, the guide groove 31 and the guide plate 26 are arranged in the vertical direction, thereby ensuring the accuracy of the limiting of the guide groove 31 and the guide plate 26, and ensuring that the guide plate 26 can be accurately inserted into the guide groove 31 to complete the limiting during the movement.

[0044] Embodiment 4

[0045] Reference Figure 3 and Figure 4 On the basis of the above-mentioned third embodiment, the fourth embodiment of the present invention provides a lifting column device 100, wherein the support member 30 further includes a reinforcing plate 34, and the reinforcing plate 34 is respectively connected to the fixing portion 32 and the extending portion 33.

[0046] In this embodiment, the fixed portion 32 and the extension portion 33 of the support member 30 are further connected by a reinforcing plate 34. Both the fixed portion 32 and the extension portion 33 are formed by stamping or bending thin sheet metal parts. Adding the reinforcing plate 34 to connect can form a triangular stable structure, thereby improving the strength of the support member 30. Although the sheet metal part itself has a certain rigidity, during use, the guide groove 31 at the end of the support member 30 farthest from the fixed portion 32 is subjected to the greatest force and is also the position most affected by the torque. The connection between the fixed portion 32 and the extension portion 33 by the reinforcing plate 34 greatly enhances the strength of the support member 30, increases the rigidity and stability, greatly increases the service life of the support member 30, and avoids deformation of the guide groove 31 at the far end of the extension portion 33.

[0053] In this embodiment, the first surface 251 and the second surface 252 for placing the support member 30 are selected as two adjacent planes, which ensures that the shield assembly 20 is stably driven and at the same time more fully limits the freedom of movement of the shield assembly 20 along the X-axis and Y-axis directions. This makes the shield assembly 20 more stable during the vertical movement and avoids the shield assembly 20 from deviating in the horizontal direction.

[0054] In addition, in this embodiment, the lifting column assembly 10 may also include a third surface and a fourth surface (not shown in the figure), and the first surface 251, the second surface 252, the third surface and the fourth surface may be connected together in sequence to form a rectangular column structure.
