[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1 - 3 , an embodiment provided by the present invention: a hospital bed nursing rack convenient for fixing, including a connecting rod 1. The top end of the connecting rod 1 is fixedly connected with a fixed plate 3. The fixed plate 3 allows medical staff to place relevant medical supplies. The inner wall of the fixed plate 3 is slidably connected with an extension plate 4. The extension plate 4 has the same function as the fixed plate 3. The extension plate 4 can increase the usable area for placement. The bottom end of the extension plate 4 is hinged with a slide block 6 through a hinge rod 5. A notch is provided on the connecting rod 1 to meet the vertical movement of the slide block 6 along the notch of the connecting rod 1. A limiting mechanism is arranged on the inner wall of the slide block 6. The top end of the connecting rod 1 is fixedly connected with a hook tube 10. There are corresponding hooks on the hook tube 10, which can hang the medicine bottle on the hook, facilitating the infusion operation for patients. The bottom end of the connecting rod 1 is provided with a connecting component. The limiting mechanism includes a wedge block 8. The wedge block 8 has an inclined surface. When the inclined surface is squeezed, the wedge block 8 will slide along the inner wall of the slide block 6. The wedge block 8 is slidably connected to the inner wall of the slide block 6. The left end of the wedge block 8 is elastically connected with the slide block 6 through a return spring 7. The outer wall of the wedge block 8 is fixedly connected with a moving rod 9. The wedge block 8 can be moved by manually moving the moving rod 9.

[0031] Refer to Figures 1 - 3, The connecting component includes a bottom plate 11. The bottom plate 11 is fixedly connected to the bottom end of the connecting rod 1. The main function of the bottom plate 11 is to connect the bidirectional lead screw 12 and the clamping plate 13. The inner wall of the bottom plate 11 penetrates and rotatably connects to the bidirectional lead screw 12. The bidirectional lead screw 12 is a lead screw structure with a special function in mechanical transmission, which can make two sets of clamping plates 13 approach each other or separate from each other. The outer wall of the bidirectional lead screw 12 is provided with clamping plates 13. The upper part of the clamping plate 13 is thread-matched with the bidirectional lead screw 12, which can make the clamping plate 13 move along the outer wall of the bidirectional lead screw 12. The outer wall of the clamping plate 13 is fixedly connected with a rubber plate 2. By contacting the rubber plate 2 with the hospital bed, the friction force is increased to ensure the stability after the clamping plate 13 clamps. The clamping plate 13 is slidably connected to the bottom end of the bottom plate 11. The bottom end of the bottom plate 11 is provided with a notch corresponding to the clamping plate 13, which can make the clamping plate 13 slide along the inner wall of the bottom plate 11.

[0032] Referring to Figures 1 - 3 , the left end of the wedge block 8 is fixedly connected to one end of the return spring 7. When the wedge block 8 moves to the left, it will compress the return spring 7. When resetting, the elastic force of the return spring 7 is used to drive the wedge block 8 to reset. The other end of the return spring 7 is fixedly connected to the inner wall of the left end of the slider 6. The moving rod 9 penetrates and is slidably connected to the inner wall of the slider 6. The slider 6 is provided with a notch corresponding to the moving rod 9, which can satisfy the sliding of the moving rod 9 in its notch. The bottom end of the extension plate 4 is hinged to one end of the hinge rod 5. When the slider 6 drives one end of the hinge rod 5 to move upward, it will make the other end of the hinge rod 5 drive the extension plate 4 to move outward. On the contrary, when the slider 6 drives the hinge rod 5 to move downward, it will make the other end of the hinge rod 5 drive the extension plate 4 to move inward. The other end of the hinge rod 5 is hinged to the left end of the slider 6. The slider 6 is slidably connected to the inner wall of the connecting rod 1. The wedge block 8 is inserted into the inner wall of the connecting rod 1. As Figure 2 shown, the connecting rod 1 is provided with a notch corresponding to the wedge block 8, which can make the wedge block 8 inserted therein to limit the slider 6 unidirectionally.

[0033] Working principle: First, when the device needs to be installed on the hospital bed for use, just align the clamping plate 13 with the installation points around the hospital bed, such as the parts blocked by the outer edge of the hospital bed or the head of the bed, etc., so that the installation points are located between the two sets of clamping plates 13. Then rotate the bidirectional lead screw 12 to make the clamping plates 13 approach each other, and make the rubber plate 2 contact the installation point to increase the friction force of the connection, and use the clamping plate 13 to contact the installation point and fix it on its surface.

[0034] When it is necessary to increase the area for medical staff to place drugs or medical devices, simply move the slider 6 upward. The slider 6 drives the hinge rod 5 to move upward, and the hinge rod 5 drives the extension plate 4 to extend outward from the inner wall of the fixed plate 3. The extension plate 4 is used to expose the increased placement space. During the upward movement of the slider 6, the inner wall notch of the connecting rod 1 squeezes the inclined surface of the wedge block 8, causing the wedge block 8 and the moving rod 9 to move leftward and compress the return spring 7, separating the wedge block 8 from the inner wall notch of the connecting rod 1. When the wedge block 8 coincides with the next inner wall notch of the connecting rod 1, the reverse elastic force of the return spring 7 drives the wedge block 8 and the moving rod 9 to reset, allowing the wedge block 8 to be inserted into the inner wall notch of the connecting rod 1, completing the one-way limit of the slider 6. The extended distance of the extension plate 4 can be adjusted according to the placement requirements. When the extension plate 4 is not in use, simply move the moving rod 9 leftward to drive the wedge block 8 to move and compress the return spring 7, separating the wedge block 8 from the inner wall notch of the connecting rod 1. Then move the slider 6 downward to drive the hinge rod 5 downward, and the hinge rod 5 drives the extension plate 4 to retract into the inner wall of the fixed plate 3. Finally, release the moving rod 9, and the reverse elastic force of the return spring 7 drives the wedge block 8 and the moving rod 9 to reset.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
