Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a multifunctional clinical nursing vehicle. Background Art

[0002] In hospitals and other medical facilities, nursing carts are a very common and commonly used medical device, mainly used to place some small medical supplies, such as IV bottles, disinfectant cotton, medicines or needles, etc. Medical workers push the nursing carts to various wards to care for patients, which greatly reduces the workload of medical workers and improves work efficiency.

[0003] Various bottles and jars will be placed on the nursing cart during use, and they are fragile items. However, current nursing carts usually do not have the ability to resist impact and vibration. In this way, when the nursing cart is running on an uneven and bumpy surface, the placed bottles and jars will easily collide, causing damage to the placed medical supplies and causing losses. Therefore, a multifunctional clinical nursing cart is proposed. Summary of the invention

[0004] The present invention provides a multifunctional clinical nursing vehicle, which aims to solve the problem that various bottles and jars which are fragile items will be placed on the nursing vehicle during use, and the existing nursing vehicles usually do not have the ability to resist impact and vibration. Thus, when the nursing vehicle is running on an uneven and bumpy surface, the placed bottles and jars will easily collide with each other, causing damage to the placed medical supplies and resulting in losses.

[0005] The embodiment of the present invention provides a multifunctional clinical nursing vehicle, comprising a nursing shell, a fence is installed at the head edge of the nursing shell, a movably connected drawer is installed on the nursing shell, a handle is installed on one side of the nursing shell, a supporting platform is installed at the tail of the nursing shell, the head corner area of ​​the supporting platform is fixedly connected to an assembly frame, the assembly frame is arranged in two pairs, each pair of assembly frames is arranged with two, the assembly frames are slidably connected with displacement rings, and the two displacement rings on one side are rotated with rotating rods, The two ends of the rotating rod respectively extend to the front and back of the supporting platform and are connected to movable wheels, the head of the assembly frame is fixedly connected to the connecting shell, and the contact rod is slidingly connected in the connecting shell, the tail of the contact rod extends into the assembly frame and is fixedly connected to the head of the displacement ring, and a compensation unit is installed in the connecting shell, and the compensation unit is connected to the head of the contact rod. The inner wall of the head of the assembly frame is connected to a protective unit, and the protective unit is respectively connected to the connecting shell and the displacement ring, and the tail of the care shell is connected to the head of the assembly frame.

[0006] By adopting the above technical scheme, the sliding connection composed of the assembly frame and the displacement ring can allow the rotating rod to achieve the purpose of changing the height area during any rotation. In this way, when the supporting platform is subjected to external influences and bumps, the height change creates conditions for sliding to reduce vibration, and the medical supplies can be protected by the enclosure to reduce the chance of falling. The care shell is driven by the handle, and different medical supplies can be placed in the drawer to facilitate subsequent use.

[0007] Furthermore, the offset unit includes a driving rod, a bending piece, an assembly rod and two telescopic modules. The driving rod is fixedly connected to the head of the contact rod, the bending piece is fixedly connected to the head of the driving rod, and the assembly rod is fixedly connected to the head of the bending piece. The two telescopic modules are respectively connected to the inner walls on both sides of the connecting shell, and the two telescopic modules are both connected to the assembly rod.

[0008] By adopting the above technical solution, after the driving rod can bear the driving force of the contact rod, the traction force generated by the assembly rod can be used to pull the two curved rotating pieces to move, so that the two curved rotating pieces can achieve the purpose of rotation adjustment.

[0009] Furthermore, the telescopic module includes a bending rotating piece, a connecting rod, a supporting rod, a traction piece and two spiral beryllium copper wires. The bending rotating piece is screwed onto the side inner wall of the connecting shell, the bending rotating piece and the assembly rod are connected to each other, the connecting rod is screwed onto the tail of the bending rotating piece, the supporting rod is fixedly connected to the side inner wall of the connecting shell, the supporting rod passes through the traction piece and is slidably connected to the traction piece, the two spiral beryllium copper wires are wrapped around the supporting rod, and the two ends of the two spiral beryllium copper wires are respectively fixedly connected to the side inner wall of the connecting shell and the traction piece, the ends of the connecting rods on the two telescopic modules that are close to each other are fixedly connected to a stop ring, and the driving rod passes through the stop ring and is slidably connected to the inner wall of the stop ring.

[0010] By adopting the above technical solution, the connecting rod can be moved in a curved trajectory during the period when the curved rotating piece carries the traction force of the assembly rod and rotates, so that the traction piece can be displaced along the direction of the supporting rod, so that the spiral beryllium copper wire 2 is in a state of bearing external force. The spiral beryllium copper wire 1 and the spiral beryllium copper wire 2 that are in a state of bearing external force can be used as components to reduce vibration, and the opposite force generated by the driving rod can suppress the displacement of the displacement circle toward the head.

[0011] Furthermore, the head of the curved rotating piece is screwed onto a variable ring, and the two variable rings are both wrapped around the assembly rod and are slidably connected to the assembly rod.

[0012] By adopting the above technical solution, the variable ring is installed on the assembly rod. When the assembly rod moves toward the head, the variable ring can be used to pull the bending rotating piece to rotate, and the variable ring is displaced on the assembly rod, so that the spiral beryllium copper wire is in a state of bearing external force.

[0013] Furthermore, two spiral beryllium copper wires are installed on the assembly rod, and the two spiral beryllium copper wires are respectively located on the side of the two variable circles away from each other, and the two ends of the spiral beryllium copper wires are respectively fixedly connected to one end of the assembly rod and one side of the variable circle.

[0014] By adopting the above technical solution, by compressing the spiral beryllium copper wire 1 to shorten and utilizing the restoring force of the spiral beryllium copper wire 1, an opposite driving force can be applied to the variable circle, thereby being able to flexibly support the displacement circle in cooperation with the spiral beryllium copper wire 2.

[0015] Furthermore, the protection unit includes a compensation shell, a suppression unit, an assembly ring, a traction rod and a rotating column. The compensation shell is fixedly connected to the inner wall of the head of the assembly frame, the suppression unit is assembled in the compensation shell, one end of the traction rod extends into the compensation shell and is connected to the suppression unit, the assembly ring is fixedly connected to the front of the connecting shell, the traction rod passes through the assembly ring and is slidably connected to the assembly ring, the other end of the traction rod is screwed to the rotating column, and the tail of the rotating column is screwed to the head of the displacement ring.

[0016] By adopting the above technical solution, the protection unit can pull the traction rod to move through the rotating column during the displacement of the displacement circle toward the head, so that the suppression unit can operate to ensure the safety of the spiral beryllium copper wire 2 and the spiral beryllium copper wire 1.

[0017] Furthermore, a spiral beryllium copper wire three is arranged on the traction rod and is located between the assembly ring and the offset shell, and two ends of the spiral beryllium copper wire three are respectively fixedly connected to the traction rod and the assembly ring.

[0018] By adopting the above technical solution, after the support platform stops shaking, the traction rod can be reset through the action of the spiral beryllium copper wire three.

[0019] Furthermore, the suppression unit includes a displacement shell, a fixed rod, a closed ring and a movable plate. The displacement shell is slidingly connected in the offset shell, one end of the fixed rod is fixedly connected to the inner wall of one side of the offset shell, the other end of the fixed rod extends into the displacement shell and is fixedly connected to the movable plate, the movable plate is slidingly connected to the inner wall of the displacement shell, and the sliding part is closed, two holes are mirrored on the movable plate, the closed ring is closed and slidingly connected to the fixed rod, the closed ring is in the displacement shell, the closed ring is fixedly connected to the inner wall of one side of the displacement shell, and transmission oil is installed in the displacement shell.

[0020] By adopting the above technical solution, the displacement shell moves along with the traction rod, so that the movable sheet can be used to compress the transmission oil, so that the transmission oil can be transferred through the two holes, and the flow of the displacement shell can be weakened by the transmission oil, thereby ensuring the protection of the spiral beryllium copper wire 1 and the spiral beryllium copper wire 2.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention supports the rotation of the rotating rod via two displacement rings. In this way, during the normal use of the rotating rod, the sliding connection between the displacement ring and the assembly frame can provide an active offset area during the high and low oscillations of the rotating rod. Therefore, when the supporting platform bears the bumpy and undulating impact, it can bring about a range of activity that changes toward the tail, which is easy to reduce the oscillation offset impact.

[0023] 2. The present invention can reduce the vibration period through the supporting platform, and both the contact rod and the connecting shell can be changed. In this way, the two bending rotating pieces can be pulled to rotate through the assembly rod and the two changing circles, and the changing circle can be displaced along the assembly rod to achieve the purpose of shortening the spiral beryllium copper wire 1. During the rotation of the bending rotating piece, the connecting rod can be pulled to move in a curved trajectory. In this way, the pulling piece can be displaced along the supporting rod to achieve the purpose of shrinking and shortening the spiral beryllium copper wire 2. The spiral beryllium copper wire 1 and the two spiral beryllium copper wires 2 in the contracted state act between the displacement circle and the assembly frame as a support, which can reduce the vibration of the supporting platform.

[0024] 3. During the movement of the displacement circle, the present invention can drive the traction rod to move through the rotating column, so that the displacement shell can move with the traction rod, so that the movable sheet can slide in the displacement shell, and the purpose of compressing the transmission oil can be achieved. In this way, the transmission oil can be transferred to the other side of the movable sheet through the two holes, and the size of the movable sheet greatly exceeds the size of the two holes, thereby allowing the displacement shell to move slowly. In this way, during the period when the spiral beryllium copper wire 1 and the spiral beryllium copper wire 2 reduce the vibration of the supporting platform, it can ensure the protective effect of offsetting the impact and prevent the spiral beryllium copper wire 1 and the spiral beryllium copper wire 2 from being directly and quickly subjected to external force impact and being damaged.

The two ends of the rotating rod 15 extend to the front and back of the supporting platform 12 respectively and are connected to the movable wheels. The head of the assembly frame 13 is fixedly connected to the connecting shell 17. The contact rod 16 is slidingly connected in the connecting shell 17. The tail of the contact rod 16 extends into the assembly frame 13 and is fixedly connected to the head of the displacement ring 14. The connecting shell 17 is provided with a compensation unit, which is connected to the head of the contact rod 16. The inner wall of the head of the assembly frame 13 is connected to a protective unit. The protective unit is respectively connected to the connecting shell 17 and the displacement ring 14. The tail of the care shell 11 is connected to the head of the assembly frame 13.

[0039] The sliding connection formed by the assembly frame 13 and the displacement ring 14 allows the rotating rod 15 to achieve the purpose of changing the height area during any rotation. In this way, when the supporting platform 12 is subjected to external influences and bumps, the height change creates conditions for sliding to reduce vibration, and the medical supplies can be protected by the enclosure 111 to reduce the chance of falling. The care shell 11 is driven by the handle 113, and different medical supplies can be placed in the drawer 112 to facilitate subsequent use.

[0040] The compensation unit includes a driving rod 18, a bending piece 19, an assembly rod 24 and two telescopic modules. The driving rod 18 is fixedly connected to the head of the contact rod 16, the bending piece 19 is fixedly connected to the head of the driving rod 18, and the assembly rod 24 is fixedly connected to the head of the bending piece 19. The two telescopic modules are respectively connected to the inner walls on both sides of the connecting shell 17, and the two telescopic modules are both connected to the assembly rod 24.

[0041] After the driving rod 18 carries the driving force of the contact rod 16 , the traction force generated by the assembly rod 24 can be used to pull the two curved rotating pieces 20 to move, so that the two curved rotating pieces 20 can achieve the purpose of rotation adjustment.

[0042] The telescopic module includes a bending rotating piece 20, a connecting rod 23, a supporting rod 21, a traction piece 27 and a spiral beryllium copper wire 28. The bending rotating piece 20 is screwed on the side inner wall of the connecting shell 17. The bending rotating piece 20 and the assembly rod 24 are connected to each other. The connecting rod 23 is screwed on the tail of the bending rotating piece 20. The supporting rod 21 is fixedly connected to the side inner wall of the connecting shell 17. The supporting rod 21 passes through the traction piece 27 and is slidably connected to the traction piece 27. The spiral beryllium copper wire 28 is wrapped around the supporting rod 21. The two ends of the spiral beryllium copper wire 28 are respectively fixedly connected to the side inner wall of the connecting shell 17 and the traction piece 27. The ends of the connecting rods 23 on the two telescopic modules that are close to each other are fixedly connected to a stop ring 22. The driving rod 18 passes through the stop ring 22 and is slidably connected to the inner wall of the stop ring 22.

[0043] During the period when the bending rotating piece 20 carries the traction force of the assembly rod 24 and rotates, the connecting rod 23 can move in a curved trajectory, so that the traction piece 27 can be displaced along the direction of the supporting rod 21, so that the spiral beryllium copper wire 28 is in a state of bearing external force. The spiral beryllium copper wire 1 26 and the spiral beryllium copper wire 28 that are in a state of bearing external force can be used as components to reduce vibration, and the opposite force generated by the driving rod 18 can suppress the displacement of the displacement circle 14 toward the head.

[0044] The head of the curved rotating piece 20 is screwed onto a variable ring 25 , and the two variable rings 25 are both surrounded by the assembly rod 24 and are both slidably connected to the assembly rod 24 .

[0045] The variable ring 25 is installed on the assembly rod 24. When the assembly rod 24 moves toward the head, the variable ring 25 can be used to pull the bending rotating piece 20 to rotate, and the variable ring 25 is displaced on the assembly rod 24, so that the spiral beryllium copper wire 26 is in a state of bearing external force.

[0046] Two spiral beryllium copper wires 26 are installed on the assembly rod 24. The two spiral beryllium copper wires 26 are respectively located on the side of the two variable circles 25 that are away from each other. The two ends of the spiral beryllium copper wires 26 are respectively fixedly connected to one end of the assembly rod 24 and one side of the variable circle 25.

[0047] By compressing the spiral beryllium copper wire 1 26 to shorten it and utilizing the restoring force of the spiral beryllium copper wire 1 26 , an opposite driving force can be applied to the variable circle 25 , thereby being able to flexibly support the displacement circle 14 in cooperation with the spiral beryllium copper wire 28 .

[0048] The protection unit includes a compensation shell 33, a suppression unit, an assembly ring 29, a traction rod 30 and a rotating column 32. The compensation shell 33 is fixedly connected to the inner wall of the head of the assembly frame 13. The suppression unit is assembled in the compensation shell 33. One end of the traction rod 30 extends into the compensation shell 33 and is connected to the suppression unit. The assembly ring 29 is fixedly connected to the front of the connecting shell 17. The traction rod 30 passes through the assembly ring 29 and is slidingly connected to the assembly ring 29. The other end of the traction rod 30 is screwed to the rotating column 32. The tail of the rotating column 32 is screwed to the head of the displacement ring 14.

[0049] The protection unit can pull the traction rod 30 to move through the rotating column 32 during the displacement of the displacement ring 14 toward the head, so that the suppression unit can operate to ensure the safety of the second spiral beryllium copper wire 28 and the first spiral beryllium copper wire 26.

[0050] A spiral beryllium copper wire 31 is arranged on the traction rod 30 between the assembly ring 29 and the offset shell 33 , and two ends of the spiral beryllium copper wire 31 are respectively fixedly connected to the traction rod 30 and the assembly ring 29 .

[0051] After the support platform 12 stops shaking, the traction rod 30 can be reset by the action of the spiral beryllium copper wire 31 .

[0052] The suppression unit includes a displacement shell 34, a fixed rod 35, a closed ring 36 and a movable sheet 38. The displacement shell 34 is slidably connected in the offset shell 33. One end of the fixed rod 35 is fixedly connected to the inner wall of one side of the offset shell 33. The other end of the fixed rod 35 extends into the displacement shell 34 and is fixedly connected to the movable sheet 38. The movable sheet 38 is slidably connected to the inner wall of the displacement shell 34, and the sliding part is closed. Two holes are mirror-mounted on the movable sheet 38. The closed ring 36 is closed and slidably connected to the fixed rod 35. The closed ring 36 is in the displacement shell 34. The closed ring 36 is fixedly connected to the inner wall of one side of the displacement shell 34. Transmission oil 37 is installed in the displacement shell 34.

[0053] By moving the displacement shell 34 along with the traction rod 30 , the movable sheet 38 can be used to compress the transmission oil 37 , so that the transmission oil 37 can be moved and transferred through the two holes, and the flow of the displacement shell 34 can be weakened by the transmission oil 37 , thereby ensuring the protection of the spiral beryllium copper wire 1 26 and the spiral beryllium copper wire 2 28 .

[0054] The specific implementation method is as follows: when the supporting platform 12 needs to reduce the vibration, the displacement ring 14 can be displaced toward the head along the assembly frame 13, and during the displacement of the displacement ring 14 toward the head, the contact rod 16 can be pulled to move toward the head, so that the driving rod 18 can move toward the head along with the contact rod 16, and during the displacement of the driving rod 18 toward the head, the assembly rod 24 can be driven by the bending piece 19 to move toward the head, and during the displacement of the assembly rod 24 toward the head, the two bending rotating pieces 20 can be pulled to rotate toward the head via the two changing rings 25, so that The two variable circles 25 can be displaced along the assembly rod 24 toward the sides away from each other, which can compress the two spiral beryllium copper wires 26. During the displacement of the bending rotating piece 20 toward the head, the connecting rod 23 can be pulled to change toward the bending trajectory of the head, so that the traction piece 27 can be pulled to displace along the supporting rod 21, thereby achieving the purpose of compressing the spiral beryllium copper wire 2 28 to become shorter. The two spiral beryllium copper wires 1 26 and the two spiral beryllium copper wires 28 are in the state of bearing external force and can support the displacement circle 14 and the assembly frame 13, thereby reducing the oscillation amplitude of the supporting platform 12.

[0055] During the displacement of the displacement ring 14, the traction rod 30 can be driven to displace via the rotating column 32, so that the displacement shell 34 and the traction rod 30 can be displaced, so that the movable sheet 38 can slide in the displacement shell 34, and the purpose of compressing the transmission oil 37 can be achieved. In this way, the transmission oil 37 can be transferred to the other side of the movable sheet 38 through the two holes, and the size of the movable sheet 38 greatly exceeds the size of the two holes, so that the displacement shell 34 can be slowly displaced, so that during the period when the spiral beryllium copper wire 1 26 and the spiral beryllium copper wire 2 28 reduce the vibration of the supporting platform 12, it can ensure that the impact is offset and has a protective effect, and prevent the spiral beryllium copper wire 1 26 and the spiral beryllium copper wire 2 28 from being directly and quickly damaged by the external force impact, so that it can ensure that the supporting platform 12 has excellent support and stability capabilities during use, so that it can be better used.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
