Description

Technical Field

[0001] This utility model belongs to the field of pallet technology, and specifically relates to a pallet rack that is easy to use. Background Technology

[0002] Medical trays are used to store, categorize, and transport various medicines and medical instruments, providing convenience and efficiency for hospitals, clinics, and other medical institutions. When medical staff need a specific medicine, surgical instrument, or examination tool, they can simply retrieve it from the corresponding tray, avoiding the problems of manual searching and wasted time. At the same time, medical trays also ensure the hygiene and safety of medical equipment. Because the surface of medical trays is usually flat and smooth, they are easy to clean and disinfect, thereby reducing the incidence of infection cases in medical institutions.

[0003] Currently, medical staff primarily use handheld trays during ward rounds to perform examinations or change medications for patients. In the operating room, surgical trolleys are used to place trays, which are then used to hold medications and instruments to prevent infection. However, these methods are inconvenient. Therefore, a rotating double-layer medical tray holder, such as the one described in patent CN206026429U, exists. This device includes upper and lower tray frames, interlocking upper and lower supports, with the upper support having threads at its bottom for connection to the main support. The lower tray frame can rotate relative to the upper support. The main support is equipped with a lifting cylinder, and the lower support has slots and clips. The lifting cylinder controls the vertical position of the tray frame, while the slots and clips control the position of the lower tray frame. However, this device cannot flexibly adjust the relative position between the two tray frames, nor can it adapt to the usage habits of medical staff, making it inconvenient. Utility Model Content

Through the universal brake wheel, the medical staff can quickly transport the device, and the device is convenient for medical staff to use.

[0065] The specific use method of the device is as follows:

[0066] For reference Figs. 1-3When the device is used, the number of trays 8 required is determined according to the medical equipment and the number of medicines and patients, and then the first fixing device is sleeved on the support 3, and the position between the first fixing devices can be adjusted according to the use habit.

[0067] The medical staff pinch the telescopic ring 504 to make the telescopic ring 504 contract and press the fixed block 402, so that the fixed block 402 presses the first telescopic spring 401, thereby making the fixed block 402 contract in the outer rod 303, and the telescopic rod 503 connected with the telescopic ring 504 and the fixed ring 501 also contracts. At this time, the medical staff pinch the telescopic ring 504 and drive the telescopic ring 504 to slide on the support 3, and the telescopic ring 504 drives the fixed ring 501 to slide on the support 3, thereby adjusting the longitudinal position of the first fixing device on the support 3. Then the medical staff can rotate the telescopic ring 504 on the circumferential position of the support 3 according to the direction in which the tray 8 needs to be rotated, so that the first fixing devices have different rotation angles, thereby facilitating the use of the medical staff. When the position of a first fixing device is adjusted, the medical staff releases the telescopic ring 504, and the telescopic rod 503 automatically presses the telescopic ring 504 and the fixed ring 501 under the influence of the second telescopic spring, so that the large ring arc 505 and the small ring arc 506 in the telescopic ring 504 automatically expand, thereby expanding the telescopic ring 504. Meanwhile, the fixed ring 501 automatically pops out along the direction of the connecting rod 302 under the influence of the first telescopic spring 401, thereby abutting against the telescopic ring 504, so that the position of the fixed block 402 is preliminarily limited by the limiting action of the fixed ring 501 and the outer rod 303 on the fixed block 402. Then the position of the telescopic ring 504 is fixed by the abutting action of the elastic force of the fixed block 402 and the first telescopic spring 401 and the re-limiting action of the telescopic ring 502, and the medical staff can adjust the position of another first fixing device according to the position. Then the reverse buckle clamp 6 connected with the large ring arc 505 is rotated, the tray 8 is placed in the tray frame 7, and the reverse buckle clamp 6 is rotated to clamp the tray 8, thereby further limiting and fixing the position of the tray frame 7.

[0068] Then the medical staff can place the required items on the tray 8, place the tray 8 in the tray frame 7 on the first fixing device, and fix the tray 8 by the reverse buckle clamp 6. The medical staff can also directly place the tray 8 in the tray frame 7 and fix the tray 8 by the reverse buckle clamp 6, push the support 3 to a specified position, and rely on the weight of the medicines in the tray frame 7, the support 3, the tray 8, and the base to make the device stable and not to be tilted, thereby stably transferring the items. When the tray 8 is not required to be used, the connection between the reverse buckle clamp 6 and the tray frame 7 is disconnected, the tray 8 is taken out, and the position of the tray frame 7 and the reverse buckle clamp 6 is rotated again to be aligned with the axial position of the support 3, thereby reducing the space occupancy.
