Detailed implementation manners

[0027] 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 efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1-6 shown, the present invention has the following specific embodiments.

[0029] Embodiment 1

[0030] A multi-class storage nursing cart for hospitals, including a storage chassis 1. At the four corners of the storage chassis 1, there are fixed support rods 101. At the lower ends of the support rods 101, there are fixed universal wheels 103. At the upper ends of the support rods 101, there is a storage upper plate 2. Between the storage chassis 1 and the storage upper plate 2, there are symmetrically arranged several support cross frames 5 on the left and right. At both ends of the support cross frame 5, there are fixed connecting collar rings 501. The connecting collar rings 501 are sleeved on the support rods 101. On the opposite surfaces of the two support cross frames 5, there are fixed limit sliders 502. Between the two support cross frames 5, there is a storage tray 4. On both sides of the storage tray 4, there are opened limit sliding grooves 402. The limit sliding grooves 402 are in sliding fit with the limit sliders 502.

[0031] In this embodiment, the storage upper plate 2 and the storage chassis 1 are connected by the support rods 101 to form an overall frame of the cart. The support cross frame 5 is slidably installed between the two support rods 101 through the connecting collar rings 501. The limit sliding grooves 402 are in sliding fit with the limit sliders 502. Then, the storage tray 4 is installed between the storage upper plate 2 and the storage chassis 1. Since the connecting collar rings 501 are slidably sleeved on the support rods 101, the support cross frame 5 can move upward. The support cross frame 5 can drive the storage tray 4 connected to it to move, adjusting the spacing between several storage trays 4, between the storage tray 4 and the storage upper plate 2, and between the storage tray 4 and the storage chassis 1, so that nursing instruments and tools of different sizes can be placed on the storage upper plate 2, the storage tray 4, and the storage chassis 1. Adjusting the spacing between the storage mechanisms to an appropriate distance can make full use of the space inside the cart.

[0032] Embodiment 2

[0033] On the surface of the support rod 101, there are several limit holes 102 opened. On the outer side of the support cross frame 5, there is a limit groove 6. In the limit groove 6, there is a slidably installed limit pin 602. The limit pin 602 cooperates with the limit holes 102. In the limit groove 6, there is a fixed return spring 601. The other end of the return spring 601 is fixed to the limit pin 602. On the limit pin 602, there is a displacement handle 603 fixed. On the storage upper plate 2, there is a push handle 201 fixed. Under the storage upper plate 2, there is a storage box 202 fixed. On the front of the storage box 202, there is a storage groove 203 opened. In the storage groove 203, there is a slidably installed pull-out storage box 204. On the front of the pull-out storage box 204, there is a first displacement handle 205 fixed. On both sides of the storage upper plate 2, there are limit card slots 206 opened. On the upper edge of the storage upper plate 2, there is a placement groove 207 opened. The placement groove 207 is internally communicated with the placement groove 207. In the limit card slots 206, there is a slidably installed limit card block 3. On one side of the limit card block 3, there is a hook 301 fixed.

[0034] In this implementation scheme, the return spring 601 can provide a certain thrust for the limit pin 602. The limit pin 602 will be inserted into the limit hole 102 under the thrust, and then the connecting collar 501 will be fixed on the support rod 101, relatively fixing the position of the support cross-frame 5. The displacement handle 603 can be used to drive the movement of the limit pin 602. Some precision nursing instruments are placed inside the pull-out storage box 204 to avoid being damaged when exposed to the outside. The hook 301 can be used to hang some nursing instruments. The limit blocks 3 are slidably installed inside the limit slots 206, and the distance between the limit blocks 3 can be adjusted according to the size of the suspended instruments to avoid collision between the suspended instruments. The limit blocks 3 can be removed from the limit slots 206 by using the placement grooves 207, which is convenient for replacing the limit blocks 3.

[0035] Embodiment 3

[0036] A second displacement handle 401 is fixedly connected to the front surface of the storage tray 4. A threaded sleeve block 503 is embedded in the support cross-frame 5. A limit bolt 504 is installed with internal threads in the threaded sleeve block 503. An interference groove 403 is formed in the limit chute 402, and the limit bolt 504 cooperates with the interference groove 403.

[0037] In this implementation scheme, when the limit bolt 504 is tightened, its end will contact the inner wall of the interference groove 403. The movement of the storage tray 4 is restricted by the frictional force to prevent the storage tray 4 from sliding out during the movement of the trolley. When the end of the limit bolt 504 does not disengage from the inside of the interference groove 403 but a part of it is inside the interference groove 403, the limit bolt 504 can be used to limit the pulling-out stroke of the storage tray 4 to avoid unconsciously pulling out the storage tray 4 completely. When the end of the limit bolt 504 is completely screwed out of the interference groove 403, the storage tray 4 can be directly pulled out and removed, which is convenient for reducing the number of storage trays 4 and increasing the internal accommodation space.

[0038] The working principle and usage process of the present invention: By cooperating the push handle 201 with the universal wheels 103, the device can be directly pushed to move. The storage chassis 1, the storage upper plate 2, the storage tray 4, and the pull-out storage box 204 can be used to store and accommodate nursing instruments. The displacement handle 603 can be used to drive the limit pin 602 to move out of the limit hole 102, releasing the restriction on the support cross-frame 5. At this time, the support cross-frame 5 can move up and down, and then the position of the storage tray 4 can be adjusted. The distance between the storage chassis 1, the storage upper plate 2, and the storage tray 4 can be reasonably adjusted according to the size of the nursing instruments inside the device. While being able to accommodate nursing instruments of different sizes, the space inside the trolley is fully utilized.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
