Preferably, an arc-shaped protrusion structure is provided on the front side of the workbench 5; the arc-shaped protrusion structure is provided with two parallel handle slots 6. Preferably, a folding frame 7 is installed on the other side of the vehicle body 4.

[0024] This embodiment provides a folding stool 2, which can be folded into a flat structure. It is designed using ergonomic principles, with knee pads 14 supporting the knees on both sides, minimizing pressure on the knees and waist, making it more comfortable for you to sit while working.

[0025] Specifically, a receiving groove is provided on the side of the vehicle body 4; the receiving groove constitutes a receiving structure for installing the folding seat 2; the folding seat 2 is slidably disposed in the receiving groove; the folding seat 2 can switch between an unfolded support state and a retracted folded state.

[0026] In this embodiment, preferably, the folding stool 2 includes: a first folding frame and a second folding frame, wherein the first folding frame and the second folding frame are arranged in an X-shape when in the unfolded support state; and are arranged horizontally when in the retracted folded state; a first crossbar support leg 22 is provided at the bottom of the first folding frame; a seat 13 is provided at the top of the first folding frame; a support short rod 23 is hinged to the middle of the back of the first folding frame; a second crossbar support leg 21 is provided at the bottom of the second folding frame; a slot plate is provided in the middle of the second folding frame; and a fixing rod 15 is provided at the top of the second folding frame.

[0027] The support rod 23 on the back of the first folding frame can be snapped into the slot plate in the middle of the second folding frame; at the same time, the fixing rod 15 on the top of the second folding frame can be pressed against the front of the first folding frame to form a stable support body. A telescopic frame is rotatably mounted on the fixed rod 15 at the top of the second folding frame; an operating table 16 is provided on the top of the telescopic frame; the operating table 16 can be slidably connected to the inner walls on both sides of the receiving groove. It can be understood that sliders can be provided on both sides of the operating table 16, and the inner walls on both sides of the receiving groove can be provided as slide rails. The operating table 16 achieves a sliding connection through the cooperation of the sliders and slide rails.

[0028] In addition, the operating table 16 is a planar structure, which can be placed inside the receiving slot against the inner surface of the receiving slot, and can be taken out when needed.

[0029] In this embodiment, preferably, the main body of the first folding frame is a single main beam structure; the main body of the second folding frame is a structure of two parallel main beams.

[0030] In this embodiment, preferably, leg kneeling pads 14 are respectively provided on the two main beams of the second folding frame.

[0031] In this embodiment, preferably, the card slot plate is provided with a number of card positions from top to bottom, and the different card positions cooperate with the support short rod 23 to achieve the height of the seat 13.

[0032] In this embodiment, preferably, the lower end of the support rod 23 has a locking block that cooperates with the locking position.

[0033] In this embodiment, preferably, the bottom of the vehicle body 4 is provided with casters 1.

[0034] Of course, there is still room for further improvement in the folding stool 2.

[0035] For example: A placement mechanism 17 is provided on the control panel.

[0036] like Figure 2 and Figure 3 As shown, the placement mechanism 17 is located on the inner wall of the operating table 16. The placement mechanism 17 includes two symmetrically arranged fixed slide rails 701, which are fixedly connected to the inner wall of the operating table 16. A placement platform 702 is slidably connected to the inner wall of the fixed slide rails 701. Four symmetrically arranged limiting springs 703 are fixedly connected to the inner wall of the placement platform 702. A limiting rod 704 is fixedly connected to the end of the limiting spring 703 away from the placement platform 702. The limiting rod 704 is slidably connected to the inner wall of the placement platform 702. A stop block 705 is fixedly connected to the end of the limiting rod 704 away from the limiting spring 703. The stop block 705 is slidably connected to the inner wall of the placement platform 702 and abuts against the surface of the water cup. The surface of the placement platform 702 is fixedly connected to... A pull block 706 is attached, and a limiting hole 712 is formed on the surface of the pull block 706. A fixing block 707 is fixedly connected to the surface of the operating table 16. A fixing spring 708 is slidably connected to the inner wall of the fixing block 707. A locking block 709 is fixedly connected to the end of the fixing spring 708 away from the fixing block 707. The locking block 709 is slidably connected to the inner wall of the fixing block 707. A locking rod 710 is fixedly connected to the inner wall of the locking block 709. The locking rod 710 is inserted into the fixing spring 708 and slidably connected to it. The locking rod 710 passes through the fixing block 707 and is slidably connected to it. The locking rod 710 is inserted into the limiting hole 712 and slidably connected to it. A limiting block 711 is fixedly connected to one end of the locking rod 710. The limiting block 711 abuts against the surface of the fixing block 707.

[0037] The overall effect of the placement mechanism 17 is as follows: by setting the placement mechanism 17, the telescopic frame 5 is rotated away from the second folding frame 2 and the operating table 16 is fixed to the other side of the telescopic frame 5. Then, the first folding frame 1 is pulled towards the second folding frame 2 and engaged with the second folding frame 2. The user's knees are placed on the protective pad 4 and they sit on the seat 3. Then, the height of the telescopic frame 5 is adjusted to a suitable position for the user. If water cups or other miscellaneous items are to be placed, the limiting block 711 is pulled away from the fixing block 707, and the fixing spring 7 is engaged. 08 deforms until the locking rod 710 disengages from the limiting hole 712. Pulling the pull block 706 away from the operating table 16 causes the placement table 702 to slide in the same direction until the locking rod 710 is aligned with the limiting hole 712 under the placement table 702. The limiting block 711 is released, and the fixing spring 708 generates elastic force to break free from the restraint, causing the locking rod 710 to abut against the limiting hole 712, thus placing the water cup in the gap between the two abutment blocks 705. Due to the elastic force generated by the limiting spring 703, the water cup is fixed on the placement table 702, completing the placement.

[0038] For example, a limit mechanism 18 is provided on the control panel 16.

[0039] like Figure 5 and Figure 6 As shown, a limiting mechanism 18 is provided on the surface of the operating table 16. The limiting mechanism 18 is located directly above the operating table 16. The limiting mechanism 18 includes two symmetrically arranged limiting frames 81. The limiting frames 81 are fixedly connected to the surface of the operating table 16. Limiting rollers 83 are slidably connected to the inner wall of the limiting frames 81. The limiting rollers 83 are slidably connected to the surface of the operating table 16. Limiting bolts 84 are fixedly connected to both sides of the limiting rollers 83. The limiting bolts 84 abut against the surface of the limiting frames 81. A connecting block 85 is fixedly connected to the surface of the limiting frames 81. A telescopic spring 86 is fixedly connected to the inner wall of the connecting block 85. A limit seat 87 is fixedly connected to the end of the telescopic spring 86 away from the connecting block 85. The limit seat 87 is slidably connected to the inner wall of the connecting block 85. A stop block 88 is fixedly connected to the end of the limit seat 87 away from the telescopic spring 86. The stop block 88 abuts against the surface of the limit bolt 84. A sliding bolt 89 is fixedly connected to one side of the limit seat 87. The sliding bolt 89 is slidably connected to the inner wall of the connecting block 85. A rotating plate 82 is rotatably connected to the surface of the operating table 16 near the seat 3.

[0040] The effect of the entire limiting mechanism 18 is that, by setting the limiting mechanism 18, when a medical record or notebook placed on the operating table 16 needs to be limited, the rotating plate 82 is opened outward, making it difficult for items such as computers to fall from the direction close to the user. Then, the stop block 88 is pushed towards the connecting block 85, causing the limiting seat 87 to slide in the same direction. The telescopic spring 86 deforms, sliding the limiting roller 83 to the other side of the stop block 88. The stop block 88 is released, and the telescopic spring 86 generates elastic force to break free from the restraint, causing the stop block 88 to abut against the limiting bolt 84, making it difficult for items such as medical records or notebooks to fall from the direction away from the user. At the same time, the limiting frames 81 on both sides can prevent items from falling from both sides, avoiding the situation where items fall and cause damage. The application of this device avoids the above problems and effectively improves the stability of the equipment.

[0041] For example, the control panel 16 is equipped with a leg protection mechanism 19.

[0042] There are two leg protection mechanisms 19, which are symmetrically arranged. Each leg protection mechanism 19 includes a fixed base 91, which is fixedly connected to the surface of the protective pad. The fixed base 91 has a limiting groove 92, and a protective spring 93 is fixedly connected to the inner wall of the limiting groove 92. There are two protective springs 93, which are mirror images of each other. A sliding rod 94 is fixedly connected to the end of the protective spring 93 away from the fixed base 91. The sliding rod 94 is slidably connected to the inner wall of the fixed base 91. A connecting plate 95 is fixedly connected to the end of the sliding rod 94 away from the protective spring 93. The connecting plate 95 abuts against the surface of the fixed base 91. The side of the connecting plate 95 near the protective pad 4 abuts against the user's knee. A limiting plate 96 is fixedly connected to the end of the connecting plate 95 away from the sliding rod 94.

[0043] The effect achieved by the entire leg protection mechanism 19 is as follows: when the user's knees need protection, the knees are placed on the protective pad 4, the knees squeeze the connecting plate 95, causing the slide rod 94 to slide in the same direction as the connecting plate 95, the protective spring 93 deforms and generates elastic force, so that it and the knee squeeze towards the connecting plate 95 to delay. When it ends, the protective spring 93 breaks free from the restraint and causes the slide rod 94 and the connecting plate 95 to return to their original positions. Example 2

[0044] This second embodiment includes the content of the first embodiment. In addition, this embodiment may include further modifications.

[0045] For example: Figures 9 to 13As shown, this embodiment provides a medical care trolley, which includes: a trolley body 4; a workbench 5 provided on the upper surface of the trolley body 4; several receiving structures for storing equipment on the side of the trolley body 4; at least one receiving structure is provided with a folding stool 2; the folding stool 2 can be detached from the receiving structure and supported on the side of the trolley body 4. A hook 8 is symmetrically provided on the back of the trolley body 4, which is used to hang another folding stool. The folding stool in this embodiment adopts a hanging method, which saves more space. If it is necessary to place other items in the receiving structure, the folding stool can be used. Therefore, the designed folding stool and folding stool 2 can be used alternately or together.

[0046] The folding stool includes: a seat plate 402, a seat cushion 401 fixed to the upper surface of the seat plate 402, a positioning block 412 fixed at the center of the bottom surface of the seat plate 402, four support legs 403 detachably installed below the seat plate 402, two T-shaped connecting blocks 405 between each pair of adjacent support legs 403, rotating connecting rods 404 between each end of the T-shaped connecting block 405 and the two adjacent support legs 403, connecting pieces 406 fixed to both sides of the T-shaped connecting block 405, connecting pins 407 inserted through the ends of both ends of the connecting pins 407, the ends of the connecting pins 407 rotatably inserted into the ends of the connecting pieces 406 or the inner walls of the support legs 403, a square connecting ring 410 below the positioning block 412, and rotating connecting plates 409 rotatably connected to the four sides of the square connecting ring 410. The ends of the connecting plate 409 away from the square connecting ring 410 are respectively located above the four T-shaped connecting blocks 405 and are rotatably connected to the T-shaped connecting blocks 405, separating the four support legs 403 from each other. The rotating connecting rod 404 and the T-shaped connecting blocks 405 located between the four support legs 403 can form a support beam between the four support legs 403. At the same time, the four rotating connecting plates 409 will unfold flat and form a cross structure with the square connecting ring 410. Then, the positioning block 412 on the bottom surface of the seat plate 402 is inserted into the middle of the square connecting ring 410, so that the seat plate 402 can be placed above the four support legs 403, so that the cushion 401, seat plate 402, support legs 403, rotating connecting rod 404 and T-shaped connecting blocks 405 form a stool, which makes it convenient for medical staff to sit after moving the nursing cart and facilitates medical staff to examine patients.

[0047] In this embodiment, the end of the hook 8 away from the main body of the nursing cart (cart body 4) is tilted upward at a certain angle and this end is a ball head. The tilt angle of the hook 8 is 15 degrees to 30 degrees. A suspension plate 408 is fixed on one side of the seat plate 402. The suspension plate 408 is made of rubber. A through suspension hole 411 is opened on the end of the rotating connecting plate 409 connected to the square connecting ring 410 and on the suspension plate 408. The inner diameter of the suspension hole 411 is greater than or equal to the outer diameter of the hook 8. The rotating connecting plate 409 and the suspension plate 408 can be suspended on the hook 8 using the suspension hole 411, so that the folded stool can be stored as a whole and the folded stool can move simultaneously with the main body of the nursing cart.

[0048] In this embodiment, a folding frame 7 is installed on the other side of the vehicle body 4. The folding frame 7 holds a trash can, making it convenient for medical staff to collect medical waste.

[0049] The folding frame 7 includes two symmetrical folding connecting plates 601, one of which is fixed to the outside of the nursing cart body. Multiple folding blocks 603 are linearly distributed between the ends of the two folding connecting plates 601. I-shaped connecting blocks 602 are rotatably connected to both sides of the folding blocks 603. The folding blocks 603 near the ends of the folding connecting plates 601 are rotatably connected to the ends of the folding connecting plates 601 through the I-shaped connecting blocks 602. The I-shaped connecting blocks 602 and the folding blocks 603 allow the two folding connecting plates 601 to be folded and adjusted. When the folding frame 6 does not need to hold a trash can, the folding frame 6 can be folded to reduce the space occupied by the nursing cart body and facilitate the storage of the nursing cart body.

[0050] When using the aforementioned medical care trolley, medical staff store the necessary work items in the trolley body and place the trash can between the two unfolded folding connecting plates 601. The medical staff can then push the trolley body to move. When the trolley is moved to the patient's side, and there is no room for the patient to sit, the medical staff simply remove the rotating connecting plate 409 that rotates onto the hook 8 through the hanging hole 411, and separate the four gathered support legs 403. At this time, the rotating connecting rod 404 and the T-shaped connecting block 405 located between the four support legs 403 will move simultaneously with the support legs 403. The connecting block 405 will gradually unfold and remain level with the ground. Next, medical staff only need to remove the seat 402 from the hook 8 and place the seat 402 above the four support legs 403. When placing it, it is necessary to ensure that the positioning block 412 is inserted into the middle of the square connecting ring 410. The four support legs 403, the rotating connecting rod 404 located between the four support legs 403, and the T-shaped connecting block 405 form the support part of the stool. The seat 402 and the seat cushion 401 are placed above the four support legs 403 to assemble a stool, which makes it convenient for medical staff to sit when using the nursing cart to treat patients' injuries, making it easier for medical staff to treat patients' conditions.
