Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rotatable hanger. Background Technology

[0002] Currently, rotatable medical care hanging racks typically consist of a base, uprights, a rotating mechanism, and crossbars. The rotating function allows medical staff to easily adjust the rack's direction, quickly meeting the nursing needs of different patients. For example, in a ward, it allows for the flexible hanging of nursing supplies such as IV bottles in appropriate positions.

[0003] These types of hanging racks have certain shortcomings. Their stability is poor; some racks are prone to wobbling when rotated or under heavy loads. If the base is small and the material is lightweight, and the rack's function is relatively simple—most can only hang items without any categorized storage—it's difficult to meet the needs of diverse nursing scenarios. Operation is also inconvenient; rotation may jam, and adjusting the height requires effort, increasing the difficulty of use for both medical staff and patients.

[0004] In the prior art, for example, a horizontally rotatable hanging bracket with publication number CN220675752U belongs to the field of hanging bracket technology. It includes a hook, a rotating mechanism, a support rod, a fixed ring, a fixing screw, a through hole, a fixing frame, a positioning hole, a fixing sleeve, and a fixing hole. In this utility model, a support rod is connected above the hook, and a rotating mechanism is set inside the support rod. The rotating mechanism includes a fixed rotating shaft, a slotted piece, a disc, a rotating shaft, a lever, and a motor. A fixed rotating shaft is set at the center of the top of the hook. A slotted piece is fitted on the fixed rotating shaft. A disc is set on one side of the slotted piece. A rotating shaft is fixed in the center of the disc. A lever is connected to the rotating shaft. A fixed ring is set at the top of the support rod. The fixed ring is an open annular shape. A through hole is opened on the fixed ring. A fixing screw is set in the through hole. A fixing frame passes through the fixed ring. A number of positioning holes are evenly opened on the fixing frame. Fixing sleeves are set at both ends of the positioning frame. A number of fixing holes are arranged in a ring on the fixing sleeves, which can be used to hang multiple items. This design also has some drawbacks. It cannot provide precise rotation positioning, and the base is small, making it prone to wobbling when rotating or carrying heavy objects. Additionally, the suspended objects are on the same plane, making them difficult to distinguish and thus unsuitable for diverse care scenarios.

[0005] Therefore, this application provides a rotatable hanger to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotatable hanger that is simple in structure and easy to use.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A rotatable hanger includes self-locking casters, a base fixedly mounted on the upper end of the casters, a rotating mechanism rotatably connected to the upper surface of the base, a support column fixedly mounted on the upper end of the rotating mechanism, a limit block fixedly connected to the upper end of the support column, a fixing mechanism fixedly mounted on the upper end of the base, several positioning holes fixedly mounted on the outer surface of the support column, and four hanger mechanisms snapped onto the outer wall of the support column.

[0009] Furthermore, the rotating mechanism includes a rotating plate, and a positioning tooth is fixedly provided on the upper end of the rotating plate.

[0010] Furthermore, the fixing mechanism includes a support block, a first spring is fixedly connected to the lower middle part of the support block, and a connecting block is fixedly connected to the lower end of the first spring.

[0011] Furthermore, a fixing tooth is fixedly connected to the lower end of the connecting block.

[0012] Furthermore, the hanging mechanism includes a hook, a fixing block is fixedly connected to the lower end of the hook, and a positioning block is fixedly connected to the lower end of the fixing block.

[0013] Furthermore, a second spring is fitted onto the lower outer end of the hook.

[0014] Furthermore, a slider is sleeved on the middle of the outer side of the hook.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a rotatable hanging bracket. Compared with existing rotatable hanging brackets, it uses interlocking positioning teeth to control the rotation and fixation of the rotating support. The interlocking positioning teeth provide precise rotation positioning, allowing the hanging bracket to accurately stop at the required angle, facilitating adjustments by medical staff according to patient position and nursing needs. Simultaneously, this method provides stable fixation, effectively preventing the hanging bracket from rotating due to accidental contact during use, ensuring the safety of suspended items. Furthermore, the structure is relatively simple, highly reliable, and has low maintenance costs.

[0017] 2. This utility model proposes a rotatable hanging rack, which, compared to existing rotatable hanging racks, features a single hook that can move freely up and down. This allows for flexible adjustment of the hook height according to actual needs, accommodating the hanging of medical items of different sizes and improving the rack's versatility. Simultaneously, it allows medical staff to conveniently hang different items in the most convenient position based on their operating habits and the patient's condition, improving nursing efficiency. Furthermore, this design is simple and practical, avoiding excessive structural complexity and facilitating daily use and maintenance. Attached Figure Description

[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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 One embodiment provided by this utility model:

[0027] A rotatable hanger includes a self-locking caster wheel 1, a base 2 fixedly mounted on the upper end of the caster wheel 1, a rotating mechanism 3 rotatably connected to the upper surface of the base 2, a support column 5 fixedly mounted on the upper end of the rotating mechanism 3, a limit block 8 fixedly connected to the upper end of the support column 5, a fixing mechanism 4 fixedly mounted on the upper end of the base 2, several positioning holes 6 fixedly mounted on the outer surface of the support column 5, and four hanger mechanisms 7 snapped onto the outer wall of the support column 5.

[0028] Specifically, three self-locking casters 1 facilitate moving the hanger to any position, while their self-locking structure can fix the position of the hanger. The base 2 is made of high-strength engineering plastic and is cylindrical. Its upper surface is rotatably connected to the rotating mechanism 3, which allows the rotating mechanism 3 to drive the support column 5 and the hanger mechanism 7 to rotate freely. The fixing mechanism 4 is responsible for fixing the rotation angle of the rotating mechanism 3. The connection between the support column 5 and the rotating mechanism 3 is reinforced or welded to reduce shaking. The outer surface of the support column 5 has four grooves from top to bottom. Each groove has several positioning holes 6. The four grooves are respectively set with hanger mechanisms 7. The hanger mechanisms 7 are fixed on the positioning holes 6 at the corresponding heights, thereby achieving precise adjustment of the height of each hanger, which is convenient for hanging different items for differentiation. The limiting block 8 is fixed to the top of the support column 5 to restrict the movement of the hanger mechanism 7.

[0029] refer to Figure 4 The rotating mechanism 3 includes a rotating plate 301, and a positioning tooth 302 is fixedly provided on the upper end of the rotating plate 301.

[0030] Specifically, a positioning tooth 302 is fixedly provided around the upper end of the rotating plate 301 to facilitate the engagement and fixation of the fixing mechanism 4 with the positioning tooth 302 on the rotating plate 301.

[0031] refer to Figure 5 The fixing mechanism 4 includes a support block 401, a first spring 402 is fixedly connected to the middle of the lower end of the support block 401, a connecting block 403 is fixedly connected to the lower end of the first spring 402, and a fixing tooth 404 is fixedly connected to the lower end of the connecting block 403.

[0032] Specifically, the first spring 402, through its own elasticity, causes the fixing tooth 404 to engage in one of the grooves of the positioning tooth 302. The support block 401 ensures that the positions of the first spring 402 and the fixing tooth 404 remain unchanged, while only the rotating plate 301 rotates. When the rotating plate 301 rotates, because the contact surface between the fixing tooth 404 and the positioning tooth 302 is inclined, the fixing tooth 404 moves upward, and the first spring 402 contracts, causing the fixing tooth 404 to move into the next groove of the positioning tooth 302. A guide post is added between the support block 401 and the connecting block 403 to restrict the movement direction of the connecting block 403, preventing it from shifting under force and improving the stability of the fixation. Because the first spring 402 itself has a large elasticity, the fixing tooth 404 and the positioning tooth 302 will not move relative to each other without external force, ensuring the fixation of the rotating mechanism 3.

[0033] refer to Figure 3 The hanging mechanism 7 includes a hook 701, a fixing block 703 fixedly connected to the lower end of the hook 701, a positioning block 705 fixedly connected to the lower end of the fixing block 703, a second spring 702 sleeved on the lower outer side of the hook 701, and a slider 704 sleeved on the middle outer side of the hook 701.

[0034] Specifically, the hook 701 is made of high-quality stainless steel and is processed with a special process. The maximum load of a single hook can reach 5kg, which can meet the hanging requirements of most medical items. The slider 704 has two symmetrical protrusions at one end for locking onto the support column 5. The hook 701, the fixing block 703 and the positioning block 705 are integrated and are installed inside the slider 704. A second spring 702 is connected between the inner wall of the slider 704 and the fixing block 703. At the same time, the second spring 702 is sleeved on the outer wall of the hook 701. When the hanging mechanism 7 needs to be moved, the hook 701 can be pulled forward, the second spring 702 retracts, the positioning block 705 disengages from the original positioning hole 6, and then the slider 704 is moved up and down to a suitable height. Finally, the hook 701 is released, the second spring 702 returns to its original state, and the positioning block 705 is re-fixed onto the new positioning hole 6.

[0035] Working principle: When a hanging rack is needed, the self-locking caster wheel 1 moves the entire rack to the appropriate position and locks it in place, keeping the base 2 stationary. Then, the support column 5 is rotated, causing the rotating mechanism 3 to rotate as well. The fixing mechanism 4 is fixedly connected to the base 2 and remains stationary. When the rotating plate 301 rotates, because the contact surface between the fixing tooth 404 and the positioning tooth 302 is inclined, the fixing tooth 404 moves upward. The first spring 402 contracts, causing the fixing tooth 404 to move into the next groove of the positioning tooth 302. Because the first spring 402 is elastic, the fixing tooth 404 and the positioning tooth 302 will not move relative to each other without external force, ensuring the fixation of the rotating mechanism 3. When the support column 5 is rotated to the appropriate position, the hook 701 is pulled forward, the second spring 702 contracts, the positioning block 705 disengages from the original positioning hole 6, and then the slider 704 is moved up and down to the appropriate height for hanging different items for differentiation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
