[0001] This utility model relates to the field of placement rack technology, and in particular to a tray placement rack. Background Technology

[0002] Surgical racks are specialized devices used in the operating room to support and hold various surgical instruments, equipment, and supplies. Their design and function are primarily to help the medical team efficiently and neatly organize and manage the tools and materials used during surgery, thereby ensuring the smooth progress of the operation and improving surgical efficiency and safety.

[0003] The height of the existing placement racks cannot be adjusted, which may require caregivers to frequently bend over or reach for items. Doing this for a long time will increase the burden on the body, especially the waist and shoulders, leading to fatigue and discomfort. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tray placement rack.

[0005] This utility model is achieved using the following technical solution: a tray placement rack, including a base, a support block fixedly connected to the top of the base, a threaded rod threadedly connected inside the support block, a handle fixedly connected to the left side of the threaded rod, a sliding groove inside the support block, a fixed block slidably connected to the outer wall of the sliding groove, a connecting rod fixedly connected inside the fixed block, a sliding wheel rotatably connected to the outer wall of the connecting rod, the sliding wheel rotatably connected to the outer wall of the sliding groove, a lifting block fixedly connected to the outer wall of the fixed block, the lifting block slidably connected to the inner wall of the support block, a tray fixedly connected to the end of the lifting block away from the base, and two sliding grooves symmetrically arranged around the center of the support block.

[0006] With the above technical solution, the operator manually rotates the handle, which is fixedly connected to the threaded rod. At the same time, the threaded rod is threaded to the support block. When the handle is turned, the friction between the threaded rod and the lifting block decreases, thereby releasing the lifting block. At this time, the tray is pulled, and the tray is fixed to the lifting block, the lifting block is fixed to the fixed block, the fixed block is fixed to the connecting rod, and the connecting rod rotates with the sliding wheel. When the sliding wheel rotates on the outer wall of the slide, the contact area between the sliding wheel and the slide is small, which can reduce resistance. At the same time, it can be adjusted according to the operator's own operating needs, reducing unnecessary bending or reaching movements and improving work efficiency.

[0007] As a further improvement to the above solution, a fixing block is fixedly connected to the bottom of the base. An inner groove is opened inside the fixing block. A slider is rotatably connected to the outer wall of the inner groove. A fixing rod is fixedly connected to the bottom of the slider. A connecting plate is fixedly connected to the bottom of the fixing rod. A rotating rod is fixedly connected inside the connecting plate. A moving wheel is rotatably connected to the outer wall of the rotating rod.

[0008] As a further improvement to the above solution, four connecting plates are provided, which are symmetrically arranged around the center of the base, and four movable wheels are provided, which are symmetrically arranged around the center of the base.

[0009] With the above technical solution, a fixing block is fixed at the bottom of the base. The fixing block causes the slider to rotate inside the fixing block through the inner groove. The slider is fixedly connected to the connecting plate through the fixing rod. The connecting plate is fixed to the rotating rod. The outer wall of the rotating rod is rotatably connected to the moving wheel, which makes it convenient for personnel to move the base, thereby greatly improving work efficiency and reducing unnecessary handling time.

[0010] As a further improvement to the above solution, a sliding groove is provided on the top of the base, an avoidance groove is provided inside the base, and a clearance groove is provided on the left side of the base.

[0011] As a further improvement to the above solution, a support rod is slidably connected to the outer wall of the sliding groove, a rubber block is fixedly connected to the bottom of the support rod, a limit plate is fixedly connected to the outer wall of the support rod, a connecting plate is contacted at the bottom of the limit plate, and an avoidance groove is opened inside the connecting plate.

[0012] As a further improvement to the above solution, the clearance groove is disposed in contact with the outer wall of the support rod, and a fixing rod is rotatably connected to the end of the connecting plate away from the support rod. The fixing rod is fixedly connected to the outer wall of the clearance groove. A slot is opened on the front of the connecting plate, and a limit block is fixedly connected to the outer wall of the clearance groove.

[0013] As a further improvement to the above solution, a locking rod is slidably connected inside the limiting block, the locking rod is slidably connected inside the base, a fixing block two is fixedly connected to the outer wall of the locking rod, a limiting block one is fixedly connected to the outer wall of the end of the locking rod away from the fixing block two, the limiting block one is slidably connected to the outer wall of the clearance groove, and a spring is provided in contact with the outer wall of the locking rod.

[0014] Through the above technical solution, the spring pushes the limiting block one to move by elastic force. The limiting block one is fixed to the locking rod, thereby causing the locking rod to slide inside the limiting block and the base, so that the locking rod is engaged with the outer wall of the slot and fixes the connecting plate one. Conversely, pulling the fixing block two can make the locking rod disengage from the slot, and the gravity of the support rod can drive the rubber block to fix the placement frame again.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows for manual rotation of the handle, which is fixedly connected to a threaded rod. Simultaneously, the threaded rod is threaded onto a support block. When the handle is turned, the friction between the threaded rod and the lifting block decreases, allowing the lifting block to be released. At this point, the tray is pulled, fixing the tray to the lifting block, the lifting block to a fixed block, and the fixed block to a connecting rod. The connecting rod and the sliding wheel rotate. When the sliding wheel rotates on the outer wall of the slide groove, the contact area between the sliding wheel and the slide groove is small, reducing resistance. Furthermore, adjustments can be made according to the operator's needs, reducing unnecessary bending or reaching movements and improving work efficiency.

[0017] This utility model uses a fixed block at the bottom of the base. The fixed block has an inner groove that allows the slider to rotate inside the fixed block. The slider is fixedly connected to the connecting plate by a fixed rod. The connecting plate is fixed to the rotating rod. The outer wall of the rotating rod is rotatably connected to the moving wheel, which makes it convenient for personnel to move the base, thereby greatly improving work efficiency and reducing unnecessary handling time.

[0032] The top of the base 1 has a sliding groove 18, the inside of the base 1 has a clearance groove 19, and the left side of the base 1 has a clearance groove 20.

[0033] A support rod 21 is slidably connected to the outer wall of the sliding groove 18. A rubber block 22 is fixedly connected to the bottom of the support rod 21. A limit plate 23 is fixedly connected to the outer wall of the support rod 21. A connecting plate 24 is provided at the bottom of the limit plate 23. An avoidance groove 25 is provided inside the connecting plate 24.

[0034] The clearance groove 19 is set on the outer wall of the support rod 21. The connecting plate 24 is rotatably connected to the end away from the support rod 21 with a fixing rod 26. The fixing rod 26 is fixedly connected to the outer wall of the clearance groove 19. The front of the connecting plate 24 has a slot 27. The outer wall of the clearance groove 20 is fixedly connected with a limit block 28.

[0035] A locking rod 29 is slidably connected inside the limiting block 28. The locking rod 29 is slidably connected inside the base 1. A fixing block 20 is fixedly connected to the outer wall of the locking rod 29. A limiting block 31 is fixedly connected to the outer wall of the end of the locking rod 29 away from the fixing block 20. The limiting block 31 is slidably connected to the outer wall of the clearance groove 20. A spring 32 is provided in contact with the outer wall of the locking rod 29. The fixing block 1 is fixed at the bottom of the base. The fixing block 1 causes the slider to rotate inside the fixing block 1 through the inner groove. The slider is fixedly connected to the connecting plate through the fixing rod. The connecting plate is fixed to the rotating rod. The outer wall of the rotating rod is rotatably connected to the moving wheel, which facilitates the movement of the base by personnel, thereby greatly improving work efficiency and reducing unnecessary handling time.

[0036] The implementation principle of a pallet rack in this embodiment is as follows: A person manually rotates handle 4, which is fixedly connected to threaded rod 3. Simultaneously, threaded rod 3 is threaded to support block 2. When handle 4 is turned, the friction between threaded rod 3 and lifting block 9 decreases, allowing lifting block 9 to be released. At this time, pallet 10 is pulled, and pallet 10 is fixed to lifting block 9. Simultaneously, lifting block 9 is fixed to fixed block 6, and fixed block 6 is fixed to connecting rod 7. Connecting rod 7 rotates with sliding wheel 8. When sliding wheel 8 rotates on the outer wall of slide groove 5, the contact area between sliding wheel 8 and slide groove 5 is small, reducing resistance. Adjustments can be made according to the operator's needs, reducing unnecessary bending or reaching movements and improving work efficiency. A fixing block 11 is fixed at the bottom of base 1. The fixing block 11, through inner groove 12, causes slider 13 to rotate inside the fixing block 11. Slider 13 is fixedly connected to connecting plate 15 via fixing rod 14. Connecting plate 15 is fixed to rotating rod 16. Rotating wheel 17 is rotatably connected to the outer wall of rotating rod 16, facilitating the operation of the pallet rack. The base 1 can be moved, which can greatly improve work efficiency and reduce unnecessary handling time. When it needs to be moved, the connecting plate 24 is stepped on. The connecting plate 24 rotates around the fixed rod 26 as the center. The surface of the connecting plate 24 contacts the limiting plate 23. The limiting plate 23 is fixed to the support rod 21, so that the support rod 21 slides on the outer wall of the sliding groove 18. At the same time, it drives the rubber block 22 to move. The rubber block 22 leaves the ground, which can push the trolley. At the same time, in order to fix the connecting plate 24 and prevent the support rod 21 from moving, the connecting plate 24 is fixed to prevent the support rod from moving. When rod 21 falls, and connecting plate 24 rotates around fixed rod 26, spring 32 pushes limit block 31 to move through elastic force. Limit block 31 is fixed to clamp rod 29, thereby causing clamp rod 29 to slide inside limit block 28 and base 1, so that clamp rod 29 is engaged with the outer wall of slot 27 and fixed connecting plate 24. Conversely, pulling fixed block 30 can make clamp rod 29 disengage from slot 27, and the gravity of support rod 21 can drive rubber block 22 to fix the placement frame again.
