[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0026] like Figure 1-Figure 4 As shown, a functional drainage rack comprises a main suspension 1, a base assembly 2 and a suspension assembly 3; the base assembly 2 is arranged at the bottom of the main suspension 1, and the base assembly 2 is placed on the ground to change the contact area between the drainage rack and the ground; the suspension assembly 3 is slidably connected to the main suspension 1 to adjust the hanging height of the drainage bag, and the base assembly 2 adaptively adjusts the contact area between the drainage rack and the ground according to the hanging height of the suspension assembly 3; the base assembly 2 comprises a fixed plate 21, a plurality of movable plates 22 and a transmission member 23; from the ground upward, the fixed plate 21, the movable plate 22 and the transmission member 23 are arranged in a fixed manner. The fixed disk 21 is provided with a plurality of sliding grooves 211 on one side where the fixed disk 21 is connected to the movable disk 22, and any movable disk 22 is slidably connected to the sliding groove 211 along the radial direction of the fixed disk 21; the transmission member 23 is coaxially rotatably connected to the fixed disk 21, and the transmission member 23 is provided with a driving groove 231 matching with any movable disk 22, and any movable disk 22 is fixedly provided with a latch 24, and the latch 24 is slidably connected to the driving groove 231; the transmission member 23 rotates clockwise to drive the movable disk 22 away from the fixed disk 21, and the transmission member 23 rotates counterclockwise to drive the movable disk 22 close to the fixed disk 21;
[0027] The user slides the suspension component 3 on the main suspension 1 to adjust the hanging height of the drainage bag. The change in the hanging height will trigger the adaptive adjustment mechanism of the base component 2. When the suspension component 3 moves upward (that is, the hanging height of the drainage bag increases), the center of gravity of the entire drainage rack rises, which may cause the stability of the drainage rack to decrease. In order to compensate for this instability, the transmission member 23 starts to rotate clockwise, and the transmission member 23 rotates through the driving groove 231 to push the pin 24 on the movable disk 22, so that the movable disk 22 slides outward (i.e., away from the fixed disk 21) along the sliding groove 211 of the fixed disk 21. In this way, the overall contact area of the base assembly 2 is increased, thereby improving the stability of the drainage rack; on the contrary, when the suspension assembly 3 moves downward (i.e., the drainage bag suspension height is reduced), the transmission member 23 rotates counterclockwise to drive the movable disk 22 to approach the fixed disk 21, thereby reducing the contact area of the base assembly 2, but still maintaining sufficient stability; therefore, the contact area between the drainage rack and the ground can be changed according to the suspension height, thereby ensuring that the drainage rack is in stable contact with the ground when the center of gravity of the drainage rack changes; through this adaptive adjustment mechanism, no matter how the suspension height of the drainage bag changes, the base assembly 2 can adjust its contact area accordingly to ensure that the drainage rack can maintain stable support at different heights.
[0028] In one embodiment, a plurality of driving grooves 231 are distributed in an involute shape on the transmission member 23, that is, the shape is generally designed to be an arc or a spiral shape, so that when the transmission member 23 rotates, the movable disk 22 can be guided to move radially along the sliding groove 211 of the fixed disk 21; as the transmission member 23 rotates, the latch 24 slides in the driving groove 231 and is guided by the contour of the driving groove 231. When the transmission member 23 rotates clockwise or counterclockwise, the contour of the driving groove 231 pushes or pulls the latch 24 on the movable disk 22, so that the movable disk 22 moves accordingly. Away from or close to the fixed disk 21; the involute distribution of the driving groove 231 allows the transmission member 23 to achieve a larger radial movement distance at a smaller rotation angle, so that the movement of the movable disk 22 can more accurately respond to the rotation of the transmission member 23, thereby improving the accuracy of the entire adaptive adjustment mechanism; through the cooperation of the involute distribution of the driving groove 231 and the latch 24, the movable disk 22 can be more evenly distributed around the fixed disk 21, which not only improves the overall stability of the base assembly 2, but also helps to disperse the force and extend the service life.
[0029] In one embodiment, the base assembly 2 also includes a threaded barrel 25, which is coaxially rotatably connected to the main suspension 1 and fixedly connected to the movable disk 22, and an external thread is provided on the outer side of the threaded barrel 25; the suspension assembly 3 includes an adjustment block 31, which is coaxially arranged with the threaded barrel 25, and the adjustment block 31 is provided with an internal thread matching the external thread, and the adjustment block 31 is threadedly connected with the threaded barrel 25, and is used to change the vertical movement of the adjustment block 31 into the rotational movement of the threaded barrel 25; when the user needs to adjust the hanging height of the drainage bag, it is achieved by operating the adjustment block 31 in the suspension assembly 3, and the adjustment block 31 is adjusted in the vertical direction. However, due to its threaded connection with the threaded barrel 25, this movement will be converted into a rotational movement of the threaded barrel 25. When the adjusting block 31 moves upward, it cooperates with the external thread of the threaded barrel 25 to drive the threaded barrel 25 to rotate clockwise. The rotation of the threaded barrel 25 drives the movable disk 22 fixedly connected thereto to rotate together, but since the movable disk 22 is restricted by the sliding groove 211 on the fixed disk 21, it slides along the radial direction of the fixed disk 21, thereby changing the contact area between the base assembly 2 and the ground, so that the contact area between the base assembly 2 and the bottom surface can be adjusted and adapted as the hanging height of the drainage bag changes.
[0030] In one embodiment, the suspension assembly 3 includes a guide rod 32, a locking rod 33 and a locking block 34; the guide rod 32 and the locking rod 33 are arranged on the main suspension 1, the adjustment block 31 is provided with a connecting portion 311, the connecting portion 311 is slidably connected with the guide rod 32, and is used to guide the threaded cylinder 25 to move in the vertical direction; the locking block 34 is connected with the connecting portion 311, the locking rod 33 is provided with a ratchet portion with an opening upward, and the locking block 34 is connected with the connecting portion 311 of the adjustment block 31, and can move with the adjustment block 31. The locking block 34 is designed with a ratchet structure matching the ratchet portion. When the locking block 34 cooperates with the ratchet portion, the ratchet will be stuck between the teeth of the ratchet, thereby preventing the adjustment block 31 from moving further, ensuring the height stability of the drainage rack and the time-limited height locking, that is, the position of the movable disk 22 can be dynamically adjusted according to the height of the adjustment block 31, thereby changing the contact area between the base assembly 2 and the ground, and maintaining the stability of the drainage rack.
[0031] In one embodiment, it also includes a negative pressure component and a traction component. Any movable disk 22 is connected to the negative pressure component through the traction component, which is used to change the horizontal movement of the movable disk 22 into the movement of the negative pressure component. The negative pressure component is installed on the fixed disk 21, and the movement of the negative pressure component and the fixed disk 21 is used to form negative pressure on the fixed disk 21 to adsorb the ground; the negative pressure component includes a suction cup 41 and a mounting groove arranged at the bottom of the fixed disk 21, and a negative pressure space 42 is formed between the suction cup 41 and the bottom of the fixed disk 21; it is composed of a suction cup 41 and a mounting groove arranged at the bottom of the fixed disk 21, and a closed negative pressure space 42 is formed between the suction cup 41 and the bottom of the fixed disk 21. When the negative pressure component is started, the air in the space is extracted to form negative pressure, so that the suction cup 41 is tightly adsorbed to the ground, and the horizontal movement of the movable disk 22 is transmitted to the negative pressure component, especially the suction cup 41 part, through the traction component; the design of the traction component enables the horizontal movement to be converted into the up and down movement of the suction cup 41, thereby forming negative pressure with the bottom surface.
[0032] In one embodiment, the traction assembly includes a traction rope 51, a traction groove 52 and a group of movable pulleys 53, one movable pulley 53 is installed on the suction cup 41, and the other movable pulley 53 is installed on the movable disk 22, the traction groove 52 is set on the fixed disk 21 and connected with one end of the suction cup 41, the traction rope 51 passes through the traction groove 52 and cooperates with a group of movable pulleys 53, one end of the traction rope 51 is fixed to the bottom of the fixed disk 21 and the other end is fixed to the groove wall of the traction groove 52; it is used to convert the horizontal movement of the movable disk 22 into the linear movement of the suction cup 41 in the vertical direction; when the height of the movable adjustment block 31 is moved, the movable disk 22 will move in the horizontal direction, thereby increasing the height of the movable disk 22. In addition, the contact area between the base assembly 2 and the bottom surface is increased. When the movable plate 22 moves, since the length of the traction rope 51 is fixed, when the movable plate 22 moves outward, the traction rope 51 is pulled outward by the movable plate 22, and the traction rope 51 connected to the suction cup 41 is affected by the outward movement of the movable plate 22. At the same time, since the movable plate 22 is located on the top of the suction cup 41, the suction cup 41 is pulled in a straight line under the action of the traction rope 51, so that a negative pressure is formed between the suction cup 41 and the bottom surface of the fixed plate 21, and the fixed plate 21 is firmly adsorbed on the bottom surface to prevent the drainage rack from tipping over; conversely, the descent of the suction cup 41 is similar, which will not be repeated;
[0033] In addition, the traction assembly in the present application has obvious compensation capabilities. Since the length of the traction rope 51 is fixed, the moving distance of the movable disk 22 corresponds to the ability of the suction cup 41 to rise and fall, that is, the distance the movable disk 22 moves outward is compensated by the rising height of the suction cup 41. In this way, the stable movement of the suction cup 41 can be achieved, thereby achieving the stable adsorption ability of the suction cup 41.
[0034] In one embodiment, any movable plate 22 is installed with a roller 6. The installation of the roller 6 allows the drainage stand to be used as an infusion stand, so that the hospital can allocate medical equipment resources more flexibly, reduce the problem of idle equipment due to single function, and optimize the overall utilization efficiency of medical resources; through the design of the roller 6, medical staff can quickly and easily move the drainage stand to the patient, reducing the tedious process of traditional methods that require multiple people to collaborate in carrying or adjusting equipment, thereby improving the efficiency and response speed of medical services.
[0035] In one embodiment, the guide rod 32 is provided with scale marks for marking the suspension height. These scale marks are used to accurately mark the suspension height, that is, the height of the movable plate 22 relative to a fixed position (such as the ground or the main suspension 1). The user can quickly and accurately understand the current suspension height by reading the value on the scale mark and adjust it as needed.
[0036] In one embodiment, a hook 7 is further provided on the top of the main suspension frame 1. The hook 7 is used to hang an IV bottle when used as an infusion stand, thereby further optimizing the overall utilization efficiency of medical resources.
[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
