[0002] A nursing cart is a mobile medical device that integrates storage, operation, and transportation functions. It is a core assistant for medical staff in performing daily nursing work in wards, outpatient clinics, and other medical settings. It is typically designed with a multi-tiered structure, equipped with drawers, shelves, and hanging baskets for the categorized storage of medications, medical devices, consumables, and medical records. Medical staff can flexibly move it to the patient's bedside to efficiently complete medication dispensing, dressing changes, vital sign monitoring, and treatment procedures, thereby significantly improving work efficiency and ensuring the timeliness and standardization of nursing services.

[0003] In existing technologies, the work surface height of nursing trolleys is usually fixed. This fixed structural design cannot flexibly match the diverse clinical work scenarios and the individualized operational needs of different medical staff, which greatly restricts the versatility and comfort of the trolley, ultimately affecting work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a height-adjustable nursing trolley workbench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable nursing trolley workbench, comprising a nursing mobile trolley, wherein an adjustment mechanism is provided on the back of the nursing mobile trolley, and a locking mechanism is provided on the outside of the adjustment mechanism;

[0006] The adjustment mechanism includes a support box, which is fixedly connected to the back of the nursing mobile trolley.

[0007] Preferably, the outer shape of the rectangular plate matches the shape of the inner wall of the support box, and the rectangular plate is slidably connected to the inner wall of the support box, so that the rectangular plate can move stably.

[0008] Preferably, the worm gear passes through the left side of the support box and rotates, and the worm gear is rotatably connected to the inner wall of the support box to provide stable support for the worm gear.

[0009] Preferably, the operating table is located on the top of the nursing mobile trolley, and a handwheel is fixedly connected to the left end of the worm gear, so that the worm gear can be rotated by driving the handwheel.

[0010] Preferably, the top of the support box has a rectangular opening, through which the support arm passes, allowing the support arm to move.

[0011] Preferably, the locking mechanism includes a fixing groove, which is fixedly connected to the left side of the support box. A fixing block is fixedly connected to the inner wall of the fixing groove, and a magnetic block is fixedly connected to the inner wall of the fixing block. A protrusion is slidably connected to the inner wall of the fixing groove, and a magnetic block is fixedly connected inside the protrusion.

[0014] Compared with the prior art, this utility model provides a height-adjustable nursing trolley workbench, which has the following beneficial effects:

[0015] 1. This height-adjustable nursing trolley workbench utilizes an adjustment mechanism that employs a worm gear and worm wheel meshing transmission to convert the rotation of the handwheel into the rotation of a threaded rod. This, in turn, drives the rectangular plate and support arm to smoothly raise and lower the workbench surface, achieving flexible and adjustable workbench height. This structure not only provides smooth transmission and good self-locking, but also adapts to the height differences of different medical staff and the diverse clinical operation scenarios, significantly improving the trolley's versatility and operational comfort, thus helping to optimize workflows and improve nursing efficiency.

[0016] 2. This height-adjustable nursing trolley workbench features a locking mechanism that keeps the internal and external splines engaged in the non-adjustable state. Simultaneously, the mutual attraction of magnetic blocks one and two creates a double lock, effectively preventing accidental rotation of the worm gear and ensuring the structural stability and safety of the workbench at a fixed height. Adjustment is achieved simply by pushing the push shaft, disengaging the splines and separating the magnetic blocks. The operation is simple and responsive, balancing flexibility in height adjustment with reliable locking during operation, thus enhancing the overall stability and operator confidence of the trolley in clinical use.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 6 A height-adjustable nursing trolley workbench includes a nursing mobile trolley 1, an adjustment mechanism 2 is provided on the back of the nursing mobile trolley 1, and a locking mechanism 3 is provided on the outside of the adjustment mechanism 2.

[0030] The adjustment mechanism 2 includes a support box 21, which is fixedly connected to the back of the nursing mobile cart 1. A threaded rod 22 is rotatably connected to the inner wall of the support box 21, and a rectangular plate 23 is threadedly connected to the outer wall of the threaded rod 22. A support arm 24 is fixedly connected to the top of the rectangular plate 23, and a worm gear 25 is fixedly connected to the outer wall of the threaded rod 22. A worm 26 is meshed on the outer ring of the worm gear 25. An operating table 27 is fixedly connected to the front of the support arm 24. The adjustment mechanism 2 can smoothly and accurately convert the rotational movement of the handwheel into the linear lifting and lowering of the operating table 27 by the meshing transmission of the worm 26 and the worm gear 25, and by utilizing the threaded engagement of the threaded rod 22 and the rectangular plate 23. It has a large transmission ratio and good self-locking performance, realizing flexible and reliable adjustment of the height of the nursing cart's operating table, and can effectively match the operating habits of different medical staff and the diverse needs of clinical scenarios.

[0031] Furthermore, the outer shape of the rectangular plate 23 matches the inner wall shape of the support box 21, and the rectangular plate 23 is slidably connected to the inner wall of the support box 21, so that the rectangular plate 23 can move stably.

[0032] Furthermore, the worm gear 26 passes through the left side of the support box 21 and rotates. The worm gear 26 is rotatably connected to the inner wall of the support box 21, providing stable support for the worm gear 26.

[0033] Furthermore, the operating table 27 is located on the top of the nursing mobile cart 1, and a handwheel is fixedly connected to the left end of the worm gear 26, so that the worm gear 26 can be rotated by the handwheel.

[0034] Furthermore, a rectangular opening is provided at the top of the support box 21, through which the support arm 24 passes, allowing the support arm 24 to move.

[0035] Example 2

[0036] See Figures 1 to 6Based on Embodiment 1, the locking mechanism 3 further includes a fixing groove 31, which is fixedly connected to the left side of the support box 21. A fixing block 32 is fixedly connected to the inner wall of the fixing groove 31, and a magnetic block 33 is fixedly connected to the inner wall of the fixing block 32. A protrusion 34 is slidably connected to the inner wall of the fixing groove 31, and a magnetic block 35 is fixedly connected inside the protrusion 34. A push shaft 36 is fixedly connected to one side of the protrusion 34, and an inner spline 37 is fixedly connected to one side of the protrusion 34. An outer spline 38 is fixedly connected to the outer wall of the worm gear 26. The locking mechanism 3 achieves mechanical locking through the meshing of the inner spline 37 and the outer spline 38, and uses the magnetic attraction of the magnetic block 33 and the magnetic block 35 to provide auxiliary holding force, thus forming a double locking mechanism. This effectively prevents the worm gear 26 from rotating unexpectedly in the non-adjusted state and ensures the absolute stability of the operating table 27 during operation. The locking can be released with one key by pushing the push shaft 36, making the operation convenient and the switching quick.

[0037] Furthermore, one side of magnetic block 2 35 is in contact with one side of magnetic block 1 33, and the sides of the two in contact are opposite magnetic poles, so that magnetic block 1 33 and magnetic block 2 35 can attract each other.

[0038] Furthermore, the inner ring of the inner spline 37 engages with the outer wall of the outer spline 38, and a slot is provided on one side of the fixing groove 31. The push shaft 36 passes through the slot, allowing the push shaft 36 to move through the slot.

[0039] In actual operation, when this device is used, pushing the push shaft 36 drives the protrusion 34 to move, so that the protrusion 34 can cause the inner spline 37 to disengage from the outer spline 38. At the same time, the protrusion 34 will also drive the second magnetic block 35 to move away from the first magnetic block 33, so that the first magnetic block 33 and the second magnetic block 35 can move away from each other and disengage. When the inner spline 37 and the outer spline 38 are no longer engaged, the worm 26 is in a rotatable state. Similarly, when the inner spline 37 and the outer spline 38 are engaged, and the second magnetic block 35 and the first magnetic block 33 are attracted to each other, the worm 26 is in a non-rotatable state. Thus, while realizing the adjustment drive, it also ensures the stability after the adjustment is completed and the use is finished.

[0040] When the worm 26 is in a rotatable state, the handwheel can be turned to rotate the worm 26. The worm 26 meshes with the worm wheel 25, so the worm 26 drives the threaded rod 22 to rotate through the worm wheel 25. Since the threaded rod 22 and the rectangular plate 23 are threadedly connected, and the rectangular plate 23 can slide and limit its movement on the inner wall of the support box 21, the rotational motion of the threaded rod 22 is converted into the linear motion of the rectangular plate 23. The rectangular plate 23 can drive the operating table 27 to rise through the support arm 24, thereby achieving the purpose of adjusting the height of the operating table 27, so that the operating table 27 can be used in operating environments of different heights.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
