[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] The embodiment of this application provides a leg dressing and placing rack, which can solve the technical problems in the prior art that the commonly used dressing and placing rack has a fixed structure, cannot be flexibly adjusted according to the height of the patient, and is inconvenient to store, occupying the space of the treatment room.

[0030] The leg dressing and placing rack in this application includes a placing mechanism and a supporting mechanism. The placing mechanism is mainly used to place the patient's leg and can flexibly adjust its own length according to the patient's height. The supporting mechanism is arranged at the bottom of the placing mechanism and is a load-bearing member. Both the placing mechanism and the supporting mechanism can synchronously expand and contract, which is convenient for storage and saves space.

[0031] Specifically, Figure 1 is a schematic structural diagram of a leg dressing and placing rack provided by an embodiment of this application, Figure 2 is a schematic structural diagram of the bottom of a leg dressing and placing rack provided by an embodiment of this application, as Figure 1 、 Figure 2As shown in the figure, the placing mechanism includes an intermediate shell 1 and leg units 2 respectively located at the head and tail ends of the intermediate shell 1 and capable of telescoping within the intermediate shell 1. A synchronous telescoping unit is provided between the two leg units 2. The intermediate shell 1 is a shell that penetrates from head to tail. During use, the horizontal height of the leg units 2 is higher than the horizontal height of the intermediate shell 1. The patient's legs are directly placed on the tops of the two leg units 2, and the two leg units 2 can synchronously and bidirectionally telescope within the intermediate shell 1 by relying on the synchronous telescoping unit, realizing simultaneous approaching or moving away from each other. As an optional embodiment, a handle is provided on the side of the intermediate shell 1 to facilitate the medical staff to take in and release the work.

[0032] Among them, the synchronous telescoping unit includes a double-end threaded rod 3 with both ends respectively threadedly connected to the two leg units 2 and a first power component that meshes with the rod body of the double-end threaded rod 3 to drive the double-end threaded rod 3 to rotate self. Both ends of the double-end threaded rod 3 are provided with threaded ends, and the threaded ends enter the two leg units 2. When the first power component drives the double-end threaded rod 3 to rotate forward or backward, the leg units 2 approach or move away from each other.

[0033] The support mechanism includes a first synchronous support foot unit 4 located at the bottom of the head end of the intermediate shell 1 and a second synchronous support foot unit 5 located at the bottom of the tail end of the intermediate shell 1. A synchronous retracting unit is provided between the first synchronous support foot unit 4 and the second synchronous support foot unit 5.

[0034] It should be noted that in this application, the head end of the intermediate shell 1 refers to the end of the intermediate shell 1 close to the patient in the use state, and the tail end of the intermediate shell 1 refers to the end of the intermediate shell 1 far from the patient. The first synchronous support foot unit 4 and the second synchronous support foot unit 5 are synchronously released through the synchronous retracting unit and supported at the four corners of the bottom of the intermediate shell 1. After bandaging, the first synchronous support foot unit 4 and the second synchronous support foot unit 5 are retracted through the synchronous retracting unit, level with the intermediate shell 1, and placed at the bottom of the intermediate shell 1.

[0035] Among them, the synchronous retracting unit includes a transmission rod 6. One end of the transmission rod 6 meshes with the first synchronous support foot unit 4, and the other end meshes with the second synchronous support foot unit 5. When the first synchronous support foot unit 4 performs the retracting or releasing action, the transmission rod 6 starts to rotate and drives the second synchronous support foot unit 5 to perform the same retracting or releasing action by relying on the meshing structure.

[0036] Furthermore, Figure 3 is a schematic structural diagram of the leg unit 2 and the guiding component in a leg bandaging placing rack provided by an embodiment of the present application, as Figure 3As shown, the leg - supporting unit 2 includes a moving plate 201 and a bracket located at one end of the moving plate 201. The end of the moving plate 201 without the bracket is located inside the middle shell 1. The bracket includes two oppositely arranged rotating rods 8 and a leg - supporting rod 9 connecting the tops of the two rotating rods 8. The middle shell 1 is a horizontally - penetrating shell. One end of the moving plate 201 slides horizontally inside the middle shell 1, and the other end of the moving plate 201 is provided with the bracket. The two rotating rods 8 in a single bracket are located on both sides in the width direction of the moving plate 201. As an alternative embodiment, to improve the comfort of the patient's placement, the middle part of the leg - supporting rod 9 is concave. The patient's legs are directly placed in the middle concave part of the two leg - supporting rods 9, and a placement pad is provided on the top of the leg - supporting rod 9.

[0037] Furthermore, to further improve the convenience of storage, the bracket in this application is set to be rotatable. In the completed storage state, the bracket is horizontally placed on the upper surface of the middle shell 1. Specifically, two limiting components 10 are oppositely arranged on the moving plate 201, and the inner side walls of the bottoms of the two rotating rods 8 are respectively rotatably connected to the outer side walls of the two limiting components 10.

[0038] Figure 8 It is a schematic structural diagram of the limiting component 10 in a leg dressing and placing rack provided by an embodiment of this application. As Figure 8 shown, the two limiting components 10 are arranged along the width direction of the moving plate 201. In one implementation manner, the limiting component 10 is a fixed block 15. A first connection hole 1501 and a first limiting hole 1502 are opened on the fixed block 15. The first connection hole 1501 and the first limiting hole 1502 are on the same horizontal line. The two first connection holes 1501 in the two fixed blocks 15 with opposite positions on the two moving plates 201 are close to each other. When the rotating rod 8 is in the vertical state, a second connection hole 801 and a second limiting hole 802 are opened at its bottom. The second limiting hole 802 is located below the second connection hole 801. Third limiting holes 202 are opened on both sides of the moving plate 201. The rotating rod 8 and the fixed block 15 form a rotating connection through the second connection hole 801 and the first connection hole 1501. In the use state, the rotating rod 8 is perpendicular to the moving plate 201. At this time, the second limiting hole 802 and the third limiting hole 202 coincide. A limiting pin is used to enter the second limiting hole 802 and the third limiting hole 202 to fix the overall vertical state of the bracket. In the storage state, the movable end of the rotating rod 8, that is, the end of the rotating rod 8 connecting the leg - supporting rod 9, rotates towards the direction of the middle shell 1 until it is horizontal with the middle shell 1. At this time, the second limiting hole 802 and the first limiting hole 1502 coincide. A limiting pin is used to enter the second limiting hole 802 and the first limiting hole 1502 to fix the overall storage state of the bracket.

[0039] Furthermore, see Figure 3, a guiding component is arranged between the moving plates 201. The guiding component includes two oppositely arranged fixing plates 7 and several guiding rods 701. Both ends of the fixing plate 7 are respectively connected to the inner walls on both sides of the middle shell 1, the rod bodies of the guiding rods 701 pass through the two fixing plates 7, and both ends of the guiding rods 701 respectively enter the plate bodies of the two moving plates 201.

[0040] A plurality of guiding rods 701 are arranged along the width direction of the moving plates 201, which are mainly used for limiting and guiding the telescopic paths of the two moving plates 201, and can also reduce the gravity of the moving plates 201 borne by the double-end threaded rod 3, ensuring the normal telescoping of the moving plates 201. As an alternative embodiment, there are two guiding rods 701, and the two symmetric guiding rods 701 are distributed on both sides of the double-end threaded rod 3. Both ends of the fixing plate 7 are fixedly formed with the side wall of the middle shell 1, which is mainly used for fixing the positions of the guiding rods 701. At the same time, the rod body of the double-end threaded rod 3 also passes through the two fixing plates 7.

[0041] Further, both ends of the double-end threaded rod 3 respectively enter the plate bodies of the two moving plates 201. Figure 4 The figure is a schematic structural diagram of the first power component in a leg dressing placement rack provided by an embodiment of the present application. As Figure 4 shown, the first power component includes a first transmission bevel gear 11 coaxially fixed with the double-end threaded rod 3, a second transmission bevel gear 12 meshing with the first transmission bevel gear 11, and a rotating end of a transmission motor 13 connected to the bottom surface of the second transmission bevel gear 12.

[0042] Internal threaded holes are formed on the side surfaces of the two moving plates 201 facing the double-end threaded rod 3. The double-end threaded rod 3 enters the internal threaded holes. The first transmission bevel gear 11 is coaxially fixed with the double-end threaded rod 3, and the tooth part of the first transmission bevel gear 11 is located around the outer circumference of the double-end threaded rod 3. The second transmission bevel gear 12 is horizontally arranged, and the second transmission bevel gear 12 is perpendicular to and meshes with the first transmission bevel gear 11. When the rotating end of the transmission motor 13 drives the second transmission bevel gear 12 to rotate horizontally forward, it drives the first transmission bevel gear 11 to rotate longitudinally, and the double-end threaded rod 3 starts to rotate self. At this time, due to the meshing relationship between the double-end threaded rod 3 and the moving plates 201, the two moving plates 201 start to approach each other. Similarly, when the rotating end of the transmission motor 13 drives the second transmission bevel gear 12 to rotate horizontally backward, the two moving plates 201 start to move away from each other. As an alternative embodiment, both the first transmission bevel gear 11 and the second transmission bevel gear 12 are located between the two fixing plates 7.

[0043] The double-end threaded rod 3, the guiding component and the first power component are all arranged in the hollow cavity inside the middle shell 1. As an alternative embodiment, the housing of the transmission motor 13 is located outside the bottom of the middle shell 1, and the rotating end of the transmission motor 13 passes through the bottom wall of the middle shell 1 and enters the hollow part inside the middle shell 1 and is connected to the second transmission bevel gear 12.

[0044] Further, Figure 5 As shown in the structural schematic diagram of the transmission rod 6 in the leg bandaging and placing rack provided by the embodiment of the present application, Figure 5 As shown, the first synchronous support foot unit 4 includes two first telescopic support feet 401 and a first synchronous rod 402. Both ends of the first synchronous rod 402 penetrate through the two first telescopic support feet 401 and are rotatably connected to the side wall of the middle shell 1. A third transmission bevel gear 403 is coaxially arranged on the rod body of the first synchronous rod 402. The second synchronous support foot unit 5 includes two second telescopic support feet 501 and a second synchronous rod 502. Both ends of the second synchronous rod 502 penetrate through the two second telescopic support feet 501 and are rotatably connected to the side wall of the middle shell 1. A fourth transmission bevel gear 503 is coaxially arranged on the rod body of the second synchronous rod 502.

[0045] On both sides of the bottom of the head end of the middle shell 1, there are first connecting ears 101. Both ends of the first synchronous rod 402 pass through the two first telescopic support feet 401 and are rotatably connected to the first connecting ears 101. When the third transmission bevel gear 403 rotates towards the center of the middle shell 1, the first synchronous rod 402 rotates synchronously, and the free ends of the two first telescopic support feet 401 move towards the center of the middle shell 1 to perform the storage action. When the third transmission bevel gear 403 rotates away from the center of the middle shell 1, the first synchronous rod 402 rotates synchronously, and the free ends of the two first telescopic support feet 401 synchronously move away from the center of the middle shell 1 to perform the release action.

[0046] Similarly, on both sides of the bottom of the tail end of the middle shell 1, there are second connecting ears 102. Both ends of the second synchronous rod 502 pass through the two second telescopic support feet 501 and are rotatably connected to the second connecting ears 102. The principle of the fourth transmission bevel gear 503 driving the two second telescopic support feet 501 to perform the storage and release actions is the same as that of the third transmission bevel gear 403 driving the two first telescopic support feet 401, and will not be elaborated here.

[0047] Further, one end of the transmission rod 6 is coaxially provided with a fifth transmission bevel gear 601 meshing with the third transmission bevel gear 403, and the other end of the transmission rod 6 is coaxially provided with a sixth transmission bevel gear 602 meshing with the fourth transmission bevel gear 503.

[0048] The transmission rod 6 is mainly provided to facilitate the simultaneous movement of the first synchronous support foot unit 4 and the second synchronous support foot unit 5, reducing the operation steps of storage and deployment. The transmission rod 6 is horizontally arranged. When any one of the first telescopic support feet 401 performs the storage action, one end of the first telescopic support foot 401 connected to the first synchronous rod 402 starts to drive the first synchronous rod 402 to rotate in the same direction, and the other first telescopic support foot 401 also synchronously stores. At the same time, when the first synchronous rod 402 rotates, the third transmission bevel gear 403 on the first synchronous rod 402 also starts to rotate. Since the third transmission bevel gear 403 meshes with the fifth transmission bevel gear 601, when the third transmission bevel gear 403 rotates, the acting force is sequentially transmitted to the fifth transmission bevel gear 601, the transmission rod 6, the sixth transmission bevel gear 602, the fourth transmission bevel gear 503, and the second synchronous rod 502, and finally reaches the two second telescopic support feet 501. Thus, the storage of the first synchronous support foot unit 4 and the second synchronous support foot unit 5 is completed.

[0049] The force transmission mode of the deployment action of the first synchronous support foot unit 4 and the second synchronous support foot unit 5 is the same as that of the storage action, only the direction of the acting force is opposite. At the same time, the way of transmitting the acting force by the meshing of the two bevel gears is a commonly used technology in the art, and will not be elaborated here too much.

[0050] However, it should be noted that the movement of any one telescopic support foot in the first synchronous support foot unit 4 and the second synchronous support foot unit 5 can drive the synchronous movement of the other three telescopic support feet, and in this application, it is not limited that a certain telescopic support foot must perform the action first.

[0051] As an optional embodiment, the first telescopic support foot 401 and the second telescopic support foot 501 in this application are both multi-section electric push rods, so as to conveniently and flexibly adjust the overall height of the leg dressing placement rack. And the telescopic ends of the multi-section electric push rods are arranged away from the middle shell 1. In the deployed state, the telescopic ends of the multi-section electric push rods contact the ground. Further, as an optional embodiment, a protective support block is arranged at the telescopic ends of the multi-section electric push rods to prevent the telescopic ends of the multi-section electric push rods from being worn.

[0052] Further, a controller 14 is arranged at the bottom of the middle shell 1. The controller 14 is electrically connected to the first synchronous support foot unit 4 and the second synchronous support foot unit 5 respectively to control the telescopic amount of the first synchronous support foot unit 4 and the second synchronous support foot unit 5, and adjust the overall height of the leg dressing placement rack in this application.

Figure 7 It is a schematic diagram of the storage state of the first telescopic support foot 401 and the second telescopic support foot 501 in a leg dressing placement rack provided by an embodiment of this application, as Figure 6 、 Figure 7As shown, the working principle of the leg dressing placement rack in this application is as follows. When folding and storing, start the driving motor 13 to rotate in the positive direction. Through the linkage of the first driving bevel gear 11 and the second driving bevel gear 12, the two moving plates 201 are retracted into the middle shell 1. Then, press the free end of the bracket to place the bracket horizontally on the upper surface of the middle shell 1 and fix it with the limiting component 10. Finally, retract the two first telescopic feet 401 and the two second telescopic feet 501 synchronously, making them in a horizontal state and storing them at the bottom of the middle shell 1.
