Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to a multi-level adjustable mobile operating table leg. Background Technology
[0002] A mobile operating table is a portable medical platform specifically designed for operating rooms, integrating patient carrying, positioning adjustment, and medical equipment compatibility. Its core functions include flexible transport via medical casters. These devices are widely used in surgical scenarios requiring complex patient positioning, such as general surgery, orthopedics, and neurosurgery. During surgery, different surgical types have specific requirements for the height and angle of the bed. For example, orthopedic surgery may require a higher bed for easier operation, while gynecological surgery may require a lower bed to ensure patient comfort. Therefore, existing mobile operating tables typically have adjustment mechanisms at the legs to adjust the bed height to meet the needs of different surgeries. Current mobile operating table legs usually use hydraulic or gear transmission for height adjustment. While this method is stable and reliable, its drawback is that it only allows for height adjustment and cannot be linked to angle adjustment. Therefore, a new structure is proposed to solve these problems. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-level adjustable mobile operating table leg to solve the problems mentioned in the background art.
[0004] This utility model is achieved through the following technical solution: a multi-level adjustable mobile operating bed leg, including: an adjustment component one and an adjustment component two, wherein the adjustment component one includes a fixed sleeve one for adjusting the height of the main body of the bed leg, and the top of the fixed sleeve one is provided with a sleeve cylinder for stabilizing the movement of the main body of the bed leg.
[0005] Above the first adjustment component is a bed leg assembly, which includes a fixing frame for mounting four sets of bed legs. A pair of second adjustment components are installed on the front and rear left side of the fixing frame. The second adjustment component includes an adjustment slider for pushing the bed back panel to adjust the angle.
[0006] In a preferred embodiment, four sets of bed leg bodies are installed at the four corners below the fixed frame. Each of the four sets of bed leg bodies is equipped with an adjustment component for adjusting the height of the bed leg assembly. Each adjustment component is equipped with a caster wheel with a self-locking structure.
[0007] In a preferred embodiment, an electric push rod is vertically installed inside the fixed sleeve. The radius of the push rod at the top of the electric push rod matches the radius of the inner side of the sleeve above the fixed sleeve. Four sets of symmetrical sliding grooves are provided on the outer side of the sleeve.
[0008] In a preferred embodiment, the bottom of the bed leg body is recessed upward to form an adjustment cavity. Four sliding strips are equidistantly arranged inside the adjustment cavity. The positions of the four sliding strips are corresponding to the positions of the four sliding grooves, and the radius of the sleeve is matched with the radius of the adjustment cavity.
[0009] In a preferred embodiment, the width and height of the sliding bar match the width and height of the sliding groove, and the thickness of the sliding bar is greater than the depth of the sliding groove.
[0010] In a preferred embodiment, an operating table body is installed above the fixing frame, and a bed back panel is installed on the left side of the operating table body via a hinge column. An adjustment slide groove is sequentially opened on the left side of the bed back panel from front to back.
[0011] In a preferred embodiment, three sets of electromagnetic brake blocks are installed at equal intervals from top to bottom on the inner side of the adjusting slide. The electromagnetic brake blocks are connected to the control mechanism inside the bed back plate. A limiting groove is opened on the front and rear inner walls of the adjusting slide.
[0012] In a preferred embodiment, the adjustment component two includes a fixed sleeve two and an adjustment slider. An electric push rod two is vertically installed inside the fixed sleeve two, and the adjustment slider is hinged to the top of the electric push rod two above the electric push rod two.
[0013] In a preferred embodiment, the top of the adjusting slider is provided with a fitting groove for engaging with the electromagnetic brake block, and the front and rear sides of the adjusting slider are respectively provided with a limiting plate for matching and limiting with the limiting groove.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting an adjustment component one, which includes a fixed sleeve one and a connecting sleeve, an electric push rod one is vertically installed inside the fixed sleeve one, and four sets of sliding grooves are opened on the outer side of the connecting sleeve. A bed leg body is provided above the adjustment component one, and four sets of sliding strips matching the specifications of the sliding grooves are provided on the inner side of the bottom of the bed leg body, and the thickness of the sliding strips is greater than the depth of the sliding grooves. In actual use, the adjustment cavity on the inner side of the bed leg body is sleeved on the outer side of the connecting sleeve, and the four sets of sliding strips are respectively located inside the four sets of sliding grooves. Due to the sliding... The thickness of the strip is greater than the depth of the sliding groove, so the inner wall of the adjustment cavity does not contact the outer side of the sleeve. In actual operation, the upper inner surface of the adjustment cavity is pushed upward by the electric push rod, thereby pushing the main body of the bed leg upward. During this process, the inner wall of the adjustment cavity never contacts the outer side of the sleeve. Then, through the connection between the four sets of sliding strips and the four sets of sliding grooves, the friction between the inner wall of the adjustment cavity and the outer side of the sleeve is converted into the friction between the four sets of sliding strips and the four sets of sliding grooves. Therefore, the friction generated during the adjustment process is greatly reduced, and the height of the main body of the bed leg can be flexibly adjusted.
[0015] 2. By setting an adjustment component two, which includes a fixed sleeve two and an adjustment slider, the adjustment slider is hinged to the top of the vertically installed electric push rod two inside the fixed sleeve two. Therefore, the adjustment slider can rotate around the top of the electric push rod two to adjust the angle. The back panel of the operating table on the left side is above the two sets of adjustment components two, and the two sets of adjustment sliders are respectively located inside the two sets of adjustment grooves on the back of the back panel. The limiting plates on the front and rear sides of the adjustment slider are respectively located inside the limiting grooves opened on the front and rear inner walls of the adjustment groove. Therefore, in actual use, when the electric push rod two is not activated, the back panel of the operating table is in a horizontal state. When the electric push rod two is activated, the back panel of the operating table is in a horizontal state. After the upward-pushing adjustment slider moves upward along the adjustment groove, the tilt angle of the back of the bed changes. Since the two sets of limiting plates are located inside the two sets of limiting grooves, the adjustment slider can be limited, ensuring that it always moves along the adjustment groove. The final effect achieved by setting adjustment component one and adjustment component two is to achieve multi-level adjustment. It can not only adjust the height of the main body of the operating table, but also adjust the angle of the back of the bed. Furthermore, adjustment component one and adjustment component two are integrated and installed on the bed leg assembly, so the angle can be adjusted at the same time as the height, increasing the linkage effect when adjusting the main body of the operating table.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0026] Please see Figures 1 to 5A multi-level adjustable mobile operating table leg includes: an adjustment component 200 and an adjustment component 300. The adjustment component 200 includes a fixed sleeve 210 for adjusting the height of the main body 220 of the table leg. The top of the fixed sleeve 210 is provided with a sleeve 211 for stabilizing the movement of the main body 220 of the table leg.
[0027] Above the adjustment component 200 is a bed leg assembly 100, which includes a mounting bracket for mounting four sets of bed legs. A pair of adjustment components 200 are mounted on the left front and rear positions of the mounting bracket. The adjustment components 200 include an adjustment slider 320 for pushing the bed back panel 110 to adjust the angle.
[0028] Four sets of bed leg bodies 220 are installed at the four corners below the fixed frame. Each of the four sets of bed leg bodies 220 has an adjustment component 200 for adjusting the height of the bed leg assembly 100. Each adjustment component 200 has a caster wheel with a self-locking structure installed below it.
[0029] An electric push rod is vertically installed inside the fixed sleeve 210. The radius of the push rod at the top of the electric push rod matches the radius of the inner side of the sleeve 211 above the fixed sleeve. Four sets of symmetrical sliding grooves 212 are opened on the outer side of the sleeve 211.
[0030] The bottom of the bed leg body 220 is recessed upward to form an adjustment cavity 230. Four sliding strips 240 are equidistantly arranged inside the adjustment cavity 230. The positions of the four sliding strips 240 are corresponding to the positions of the four sliding grooves 212, and the radius of the sleeve 211 matches the radius of the adjustment cavity 230.
[0031] The width and height of the slider 240 match the width and height of the slider groove 212, and the thickness of the slider 240 is greater than the depth of the slider groove 212.
[0032] The main body of the operating table is installed above the fixed frame. The back panel 110 of the operating table is installed on the left side of the main body of the operating table via a hinge column. An adjustment slide groove 111 is opened from front to back on the left side of the back panel 110.
[0033] Three sets of electromagnetic brake blocks 112 are installed at equal intervals from top to bottom on the inner side of the adjusting slide 111. The electromagnetic brake blocks 112 are connected to the control mechanism inside the bed back plate 110. A limit groove 113 is opened on the front and rear inner walls of the adjusting slide 111.
[0034] Adjustment component 2 300 includes fixed sleeve 2 310 and adjustment slider 320. Electric push rod 2 is vertically installed inside fixed sleeve 2 310, and adjustment slider 320 is hinged above the top of electric push rod 2.
[0035] The top of the adjusting slider 320 is provided with a fitting groove 321 that engages with the electromagnetic brake block 112, and the front and rear sides of the adjusting slider 320 are respectively provided with a limiting plate 322 for matching and limiting with the limiting groove 113.
[0036] Example 1: Please refer to Figure 1 and Figure 2 In actual use, the main body of the operating table is mounted on top of the leg assembly 100. The leg assembly 100 includes a fixed frame and four sets of main leg bodies 220. Specifically, the four sets of main leg bodies 220 are mounted at the four corners of the bottom of the fixed frame, and the main body of the operating table is mounted on top of the fixed frame. Each set of main leg bodies 220 has an adjustment component 200 installed below it, and each adjustment component 200 has a caster wheel with a self-locking structure installed below it. The adjustment component 200 includes a fixed sleeve 210 and a connecting sleeve 211. An electric push rod is vertically mounted inside the fixed sleeve 210. The four sets of electric push rods are synchronized. The top of the electric push rod... The push rod can extend or retract flexibly into the inner side of the sleeve 211. Four sets of sliding grooves 212 are symmetrically opened on the outer side of the sleeve 211. The bottom of the bed leg body 220 is recessed upward to form an adjustment cavity 230. The top of the push rod above the electric push rod is fixed to the upper surface of the inner side of the adjustment cavity 230. Four sliding strips 240 are symmetrically arranged inside the adjustment cavity 230. The specifications of the sliding strips 240 match the specifications of the sliding grooves 212, but the thickness of the sliding strips 240 is greater than the depth of the sliding grooves 212. That is, after the four sets of sliding strips 240 are located inside the four sets of sliding grooves 212, the inner wall of the adjustment cavity 230 never contacts the outer side of the sleeve 211.
[0037] In actual use, all four sets of electric push rods are activated simultaneously. These four electric push rods simultaneously push the push rod upwards, causing the push rod to push the upper inner surface of the adjustment cavity 230 upwards. This pushes the bed leg body 220 upwards, thereby changing the height of the operating table body. During this process, the four sets of sliding strips 240 move upwards along the four sets of sliding grooves 212 respectively, and the inner wall of the adjustment cavity 230 never contacts the outer side of the sleeve 211. Therefore, through the connection between the four sets of sliding strips 240 and the four sets of sliding grooves 212, the adjustment cavity 230 can be adjusted upwards. The friction between the inner side and the outer side of the sleeve 211 is converted into friction as the four sets of sliding strips 240 slide on the inner side of the four sets of sliding grooves 212. This greatly reduces the internal friction generated when the height of the bed leg body 220 is adjusted. It should be noted that the sliding strips 240 are made of bearing steel, which has high hardness and high wear resistance. The inner side of the sliding grooves 212 is made of tin bronze, which works in conjunction with the sliding strips 240 and has good wear resistance. The final effect is that the height of the operating table can be flexibly adjusted and the internal friction generated during the adjustment process can be effectively reduced.
[0038] Example 2: Please refer to Figures 1 to 5 The operating table has a backrest 110 hinged to its left side. A pair of adjusting grooves 111 are located on the front and back of the left side of the backrest 110. Three sets of electromagnetic brake blocks 112 are installed inside the adjusting grooves 111 from top to bottom. Each set of electromagnetic brake blocks 112 is connected to a control mechanism inside the backrest 110. A limiting groove 113 is also provided on the front and back inner walls of the adjusting grooves 111. An adjusting assembly 300 is installed on the front and back of the top left side of the fixing frame. The adjusting assembly 300 includes a fixing sleeve 310 and an adjusting slider 320. An electric push rod 2 is vertically installed inside the fixing sleeve 310. The two sets of electric push rods 2 are synchronized. The mechanism has an adjusting slider 320 hinged to the top of the push rod 2 above the electric push rod 2, so the adjusting slider 320 can rotate flexibly around the top of the push rod 2. The front and rear sides of the adjusting slider 320 are respectively provided with a limiting plate 322 that matches the limiting groove 113, and the top of the adjusting slider 320 is provided with a fitting groove 321 that fits and connects with the electromagnetic brake block 112. The two sets of adjusting sliders 320 are respectively located inside the two sets of adjusting slide grooves 111, and the two sets of limiting plates 322 are respectively located inside the two sets of limiting grooves 113. The side of the adjusting slider 320 with the fitting groove 321 is opposite to the side of the adjusting slide groove 111 where the electromagnetic brake block 112 is installed.
[0039] While adjusting the height of the operating table, if neither of the two sets of electric push rods is activated, the backrest 110 of the table is in a horizontal state, meaning the patient is lying flat. The two sets of adjusting sliders 320 are located at the bottom of the two sets of adjusting grooves 111, and the electromagnetic brake block 112 at the bottom is engaged with the fitting groove 321. After the height adjustment is completed, the two sets of electric push rods can be activated. When the two sets of electric push rods are activated, the electromagnetic brake block 112 at the bottom disengages from the fitting groove 321, releasing the locking state of the adjusting slider 320. The two sets of electric push rods push the two sets of push rods upward, thereby causing the two sets of adjusting sliders 320 to slide upward from the bottom of the adjusting groove 111. The two sets of limiting plates 322 slide along the two sets of limiting grooves 113, thereby firmly restricting the adjusting slider 320 inside the adjusting groove 111.
[0040] As the adjusting slider 320 moves, the left side of the bed back panel 110 gradually rotates upward from a horizontal position and adjusts the angle, with the maximum adjustment angle not exceeding 30 degrees. When the bed back panel 110 reaches the maximum angle, the uppermost electromagnetic brake block 112 engages with the fitting groove 321, thereby fixing the position of the bed back panel 110. Therefore, by engaging the fitting groove 321 with three sets of electromagnetic brake blocks 112 at different positions, the angle adjustment of the bed back panel 110 can be controlled. Thus, the final effect is that the angle of the bed back panel 110 can be flexibly adjusted. In addition, when used with the adjusting component 200, a multi-level adjustment effect can be achieved. Both the adjusting component 200 and the adjusting component 300 are integrated and installed on the fixing frame in the bed leg assembly 100, thus significantly improving the adjustment linkage between the adjusting component 200 and the adjusting component 300, and greatly improving the adjustment flexibility of the operating table body.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
