Universal wheels for moving the cart body 1 are fixedly installed at the bottom of the cart body 1. A drawer is provided at the top of the cart body 1. A storage box 4 for storing nursing items is provided on the lower inner side of the cart body 1. Two sets of storage boxes 4 are provided, and the two sets of storage boxes 4 are fixedly connected by a pull block. The pull block can pull out and raise / lower both sets of storage boxes 4. A pull-out assembly 2 is provided between the storage box 4 and the cart body 1. The pull-out assembly 2 supports the storage box 4 and can be pulled outwards for convenient access to and storage of nursing items. The pull-out assembly 2 includes a lifting block 23 and a fixing block 22. The lifting block 23 and the fixing block 22 provide support. The lifting block 23 is slidably connected to the lower inner side of the cart body 1, and the fixing block 22 is fixedly connected to the top of the lifting block 23.

[0019] Furthermore, the top of the fixing block 22 is provided with a groove for supporting the sliding plate 21 and providing sliding space for the sliding plate 21. Positioning grooves 27 are provided on both the left and right sides of the groove to cooperate with the positioning rods 26 to limit the sliding distance.

The lifting block 23 is slidably connected to the lower inner side of the vehicle body 1 through the lifting assembly 3. After the storage box 4 is pulled outward, the lifting component 3 can raise and lower the storage box 4 to the same height as the back of the drawer. At this time, it is convenient to take out and put in care items without having to bend over and search inside the lower part of the vehicle body 1, which improves the convenience of taking out and putting in items. The rear surface of the fixing block 22 is fixedly connected to the support block 25 with the support roller 24. The rear end of the support block 25 is rotatably connected to the left and right sides of the roller 24. The roller 24 rolls on the bottom of the slide plate 21. The setting of the roller 24 can support the slide plate 21 and reduce friction with the slide plate 21, making it convenient to pull out and move the slide plate 21.

[0020] Reference Figure 1 , Figure 4 and Figure 5The lifting assembly 3 includes a fixed vertical frame 31. The fixed vertical frame 31, in conjunction with the insertion holes 33 and the limiting rods 38, can support the lifting block 23. Four sets of fixed vertical frames 31 are provided, and are respectively fixedly connected to the lower inner left and right sides of the vehicle body 1. The upper and lower ends of the four sets of fixed vertical frames 31 near the storage box 4 are provided with insertion holes 33 that cooperate with the limiting rods 38 to support and limit the lifting block 23 and the storage box 4. Limiting rods 38, which are inserted into the insertion holes 33 and slidably connected to the left and right sides of the lifting block 23, limit the lifting block 23. The limiting rods 38 are U-shaped with their openings facing outwards. Two sets of U-shaped rods are provided simultaneously, which can be inserted into the four sockets 33 respectively, thus stably supporting the lifting block 23. The ends of the two sets of limiting rods 38 that are far apart are both set as inclined surfaces. By setting the inclined surfaces, when the rods rise, they can be directly squeezed to make the two sets of limiting rods 38 move inward at the same time, and the spring 36 is compressed. When they move to the appropriate height, the reverse force of the spring 36 being compressed can drive the limiting rods 38 to reset and insert into the corresponding sockets 33 above, limiting the lifting block 23 and the storage box 4 to the upper position of the vehicle body 1. At this time, it is convenient to take out and put in the nursing items in the storage box 4.

[0021] Furthermore, two sets of limiting rods 38 are provided. The ends of the two sets of limiting rods 38 that are far apart are respectively inserted into the inner walls of the corresponding insertion holes 33. The upper and lower ends of the two sets of limiting rods 38 that are close to each other are fixedly connected to guide rods 39 for driving the movement of the limiting rods 38. The middle of the lifting block 23 is provided with a slot 37 for providing movement space for the guide block 34 and the limiting rods 38. The inner wall of the slot 37 is slidably connected to a guide block 34 for cooperating with the guide groove 35 to drive the guide block 34. The guide block 34 is H-shaped. The H-shape provides movement space for the limiting rods 38 and also cooperates with the guide groove 35 and the guide rods 39 to drive the limiting rods 38 to move. The two sets of limiting rods 38 are slidably connected to the left and right sides of the guide block 34. The upper and lower surfaces of the guide block 34 are both provided with inclined guide rods that can drive the guide rods 39 to move left and right by moving back and forth. The guide groove 35 is inclined and has two sets of symmetrically arranged on the guide block 34 near the left and right sides. The two sets of guide grooves 35 can work with the two sets of guide rods 39 to drive the two sets of limiting rods 38 to move synchronously towards the center. The guide rods 39 are slidably connected to the inner wall of the guide groove 35. The rear end of the guide block 34 is fixedly connected to a pull rod 32 that drives the guide block 34 to move. The pull rod 32 passes through and is slidably connected to the rear side of the lifting block 23. The guide block 34 and the lifting block 23 are elastically connected by a spring 36. The spring 36 is sleeved on the outer wall of the pull rod 32. One end of the spring 36 is fixedly connected to the rear surface of the guide block 34, and the other end of the spring 36 is fixedly connected to the inner wall of the lifting block 23. The setting of the spring 36 ensures that the limiting rods 38 are always inserted into the insertion hole 33 to limit the lifting block 23.

[0022] Working principle: When in use, after moving the vehicle body 1 to the nursing position, the storage box 4 and the slide plate 21 are moved by the pull block. The storage box 4 slides outward along the slide groove at the top of the fixed block 22. At this time, the rollers 24 at the bottom of the slide plate 21 provide rolling support and reduce sliding friction. At the same time, the positioning rods 26 on both sides of the slide plate 21 slide along the positioning grooves 27 to limit the pull-out stroke of the storage box 4 and avoid excessive pulling out.

[0023] After the storage box 4 is pulled out, it is pushed upwards, causing the lifting block 23 and the storage box 4 to rise. At this time, the inclined surface of the limiting rod 38 is squeezed by the fixed vertical frame 31, causing the limiting rod 38 to move inwards and drive the guide rod 39 to move inwards. The guide rod 39 slides in the inclined guide groove 35, driving the guide groove 35 and the guide block 34 to move backwards and compress the spring 36. When the lifting block 23 moves to the target height, the rebound force of the spring 36 pushes the guide block 34 forward. The guide block 34 moves forward through the guide groove 35 and the guide rod 39. With the cooperation of the limit rod 38, the storage box 4 is locked at the corresponding height by inserting the limit rod 38 into the corresponding socket 33 of the fixed vertical frame 31. At this time, medical staff can easily pick up and put down items, so that medical staff do not need to bend over to search for nursing items on the inner side of the lower part of the vehicle body 1. This improves the convenience of picking up and putting down items, reduces the workload of medical staff, and improves the efficiency of nursing work. When it is necessary to reset, pull the pull rod 32 to move the guide block 34 backward, so that the limit rod 38 is disengaged from the socket 33. Then, move the lifting block 23 down and push the slide plate 21 to reset.
