Description

Technical Field

[0001] The present invention relates to the field of medical suspension towers, and particularly to a medical suspension tower with a load balance adjustment device. Background Art

[0002] A medical suspension tower is used to be installed on the ceiling and is used to provide a combination of medical gases, power supplies, communication calls, network terminals, etc., and can carry medical instruments required by patients to provide a good nursing space. During the use of the medical suspension tower, the height control component in the medical suspension tower is adjusted to make the box component on the medical suspension tower hover at any fixed position; and the height control component has relatively high requirements for the balance adjustment of the medical suspension tower during use, and appropriate balance adjustment can make the operation of the height adjustment device more comfortable. Therefore, when installing the medical suspension tower, it is necessary to adjust the balance between the gas spring and the box component according to the load from the box component borne by the drive component.

[0003] When the existing medical suspension tower is installed, due to different actual requirements, the loads of the box components are also different, so it is necessary to adjust during installation. The adjustment method is to change the distance between the gas spring and the box component to change the moment of the gas spring and thus achieve the balance between the gas spring and the box component. However, due to the complex structure of the connection between the gas spring and the box component of the existing medical suspension tower, when adjusting the positions of the two, it is necessary to remove more fixing parts such as screws, and it is necessary to use a tooling to hold the box component to carry out the adjustment. Moreover, during multiple debugging processes, multiple disassembly and assembly operations are required, which is time-consuming and laborious. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a medical suspension tower with a load balance adjustment device, which can achieve the balance adjustment between the gas spring and the box component by adjusting the adjustment component, and has convenient operation and a simple structure.

[0005] The present invention is realized through the following technical solutions:

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] As Figure 1 and Figure 2 shown, a medical pendant with a load balance adjustment device 10 corresponding to a preferred embodiment of the present invention includes a height control assembly 9, a box body assembly 1, a drive assembly 2 for driving the movement of the box body assembly 1, and a load balance adjustment device 10. The drive assembly 2 needs to bear the load from the box body assembly 1, and the drive assembly 2 includes a gas spring 22. The height control assembly 9 includes a Bowden cable 91. The Bowden cable 91 is connected to the gas spring 22. The height control assembly 9 triggers the gas spring 22 through the Bowden cable 91 to adjust the height of the box body assembly 1. The load balance adjustment device 10 includes a fixed flange 4 connected to the box body assembly 1, a sliding adjustment seat 5 connected to the gas spring 22, and an adjustment assembly 11. The adjustment assembly 11 is adjustably connected between the fixed flange 4 and the sliding adjustment seat 5. Further referring to Figures 3 to 4 , when the adjustment assembly 11 is adjusted, the movement directions of the fixed flange 4 and the sliding adjustment seat 5 are opposite, that is, they approach or move away from each other. Specifically, referring to Figure 3 and Figure 4 , in this embodiment, when the adjustment assembly 10 is adjusted clockwise, the fixed flange 4 and the sliding adjustment seat 5 move away from each other (as shown by the arrow F), at this time, the distance between the gas spring 22 and the box body assembly 1 becomes farther, and the moment of the gas spring 22 increases; when the adjustment assembly 10 is adjusted counterclockwise, the fixed flange 4 and the sliding adjustment seat 5 approach each other (as shown by the arrow G), at this time, the distance between the gas spring 22 and the box body assembly 1 becomes closer, and the moment of the gas spring 22 decreases.

[0029] The driving component 2 includes an upper fixing plate 21, a gas spring 22, a side plate 23, and a rotating shaft 24 connected to the side plate 23. The upper fixing plate 21 is connected to the fixing component 3 of the medical suspension tower to fix the driving component 2. One end of the gas spring 22 is connected to the upper fixing plate 21, and the other end is connected to the sliding adjustment seat 5. One end of the side plate 23 is fixed to the upper fixing plate 21, and the other end is connected to the box body component 1. Specifically, the rotating shaft 24 sequentially passes through the side plate 23, the fixing flange 4, and the box body component 1 to connect the side plate 23 and the box body component 1. Moreover, the box body component 1 can rotate around the central axis of the rotating shaft 24 to swing the box body component 1 up and down.

[0030] Further referring to Figures 5 to 6 , the fixing flange 4 is provided with a pair of sliding grooves 41, a pair of guide grooves 42, and a first threaded hole 43. The guide groove 42 has a long strip structure. The first threaded hole 43 penetrates through the fixing flange 4. The sliding adjustment seat 5 is provided with a sliding table 51 and a second threaded hole 52. There are a pair of sliding tables 51, and both are provided with third threaded holes 53. The pair of sliding tables 51 respectively pass through the pair of sliding grooves 41 and can slide in the sliding grooves 41. The second threaded hole 52 penetrates through the sliding adjustment seat 5.

[0031] The adjusting component 11 includes an adjusting rod 6, a locking nut 8, and a locking screw 7. The two ends of the adjusting rod 6 are respectively connected to the fixing flange 4 and the sliding adjustment seat 5. The adjusting rod 6 includes a first threaded rod 61, a second threaded rod 62, and a hexagonal adjusting part 63. The first threaded rod 61 is connected to the fixing flange 4; specifically, the first threaded rod 61 passes through the first threaded hole 43 of the fixing flange 4. The second threaded rod 62 is connected to the sliding adjustment seat 5, and the spiral direction of the thread on the second threaded rod 62 is opposite to the spiral direction of the thread on the first threaded rod 61; specifically, the second threaded rod 62 passes through the second threaded hole 52 of the sliding adjustment seat 5, the second threaded rod 62 is a left-handed thread, and the first threaded rod 61 is a right-handed thread. The two ends of the hexagonal adjusting part 63 are respectively fixedly connected to the first threaded rod 61 and the second threaded rod 62; preferably, the hexagonal adjusting part 63 is integrally formed with the first threaded rod 61 and the second threaded rod 62. The hexagonal adjusting part 63 can be connected to tools such as a hexagonal wrench to facilitate the user to adjust the adjusting rod 6. When it is necessary to adjust the distance between the gas spring 22 and the box body component 1, rotate the adjusting rod 6. Since the spiral directions of the threads on the first threaded rod 61 and the second threaded rod 62 are opposite, when the first threaded rod 61 is screwed into the fixing flange 4, the second threaded rod 62 is screwed into the sliding adjustment seat 5, so that the distance between the fixing flange 4 and the sliding adjustment seat 5 is reduced; on the contrary, when the first threaded rod 61 is screwed out of the fixing flange 4, the second threaded rod 62 is screwed out of the sliding adjustment seat 5, so that the distance between the fixing flange 4 and the sliding adjustment seat 7 is increased; thus, the distance between the gas spring 22 and the box body component 1 is adjusted. Furthermore, the moment arm between the gas spring 22 and the rotating shaft 24 is changed, so that the moment of the gas spring 22 changes.

[0032] A pair of locking screws 7 are provided. The locking screws 7 are sequentially passed through the guide groove 42 and the third threaded hole 53 to fix the fixed flange 4 and the sliding adjustment seat 5. A pair of locking nuts 8 are provided. The pair of locking nuts 8 are respectively sleeved on the first threaded rod 61 and the second threaded rod 62; and the pair of locking nuts 8 are respectively abutted against the sliding adjustment seat 5 and the fixed flange 4 to keep a fixed distance between the sliding adjustment seat 5 and the fixed flange 4.

[0033] During use, the medical suspension tower is installed on the ceiling, and the locking nuts 8 and the locking screws 7 are loosened, and the adjusting rod 6 is rotated; at this time, the sliding adjustment seat 5 slides relative to the fixed flange 4 and the distance between the two changes, and the distance between the gas spring 22 and the box body assembly 1 changes, so that the distance between the gas spring 22 and the rotating shaft 24 changes, thereby changing the torque of the gas spring 22; when the balance between the gas spring 22 and the box body assembly 1 is reached, the locking screws 7 and the locking nuts 8 are tightened. By providing the adjusting assembly 11 in the present invention, adjusting the adjusting assembly 11 can make the fixed flange 4 and the sliding adjustment seat 5 move in opposite directions, that is, approach or move away from each other, thereby adjusting the distance between the gas spring 22 connected to the sliding adjustment seat 5 and the box body assembly 1 connected to the fixed flange 4, and adjusting the balance between the gas spring 22 and the box body assembly 4. By providing the adjusting rod 6 with opposite thread helix directions at the left and right ends, and the slidable sliding adjustment seat 5 and the fixed flange 4, rotating the adjusting rod 6 can adjust the distance between the sliding adjustment seat 5 and the fixed flange 4, without the need to use additional tooling to hold the box body assembly 1, and the adjustment process is simple; and the lever arm between the gas spring 22 connected to the sliding adjustment seat 5 and the rotating shaft 24 can be changed, and the torque of the gas spring 22 can be changed to achieve the balance adjustment between the gas spring 22 and the box body assembly 1. By providing the locking screws 7 and the locking nuts 8, when performing the balance adjustment, only the locking screws 7 and the locking nuts 8 need to be loosened for adjustment, without the need to disassemble too many fixing parts, simplifying the locking structure, reducing costs, and this locking structure is also relatively stable.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent of the present invention should be subject to the appended claims.
