Description

Technical Field

[0001] This utility model relates to the field of medical cart technology, and in particular to an auxiliary device. Background Technology

[0002] Medical trolleys are protective transport equipment for patients in wards. They are suitable for use in large hospitals, health clinics, pharmacies, psychiatric hospitals, and other daily use, and can greatly reduce the workload of caregivers.

[0003] Existing medical trolleys use locking tabs on the surface of the casters to secure auxiliary devices. However, because the casters and auxiliary devices are rotatably connected, the auxiliary device can still rotate even after a single caster is locked. This necessitates locking both casters simultaneously, extending the time unnecessarily and increasing unnecessary time waste during clinical emergency care. Therefore, an auxiliary device is proposed to solve the above problems. Utility Model Content

[0004] This utility model provides an auxiliary device that solves the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary device, including a lower plate, a middle rod fixed to the upper end of the lower plate, an upper plate fixed to the upper end of the middle rod, a positioning rod fixed to the lower end of the lower plate, a support rod rotatably connected to the surface of the positioning rod, an upper top plate rotatably connected to one end of the support rod, the upper end of the upper top plate rotatably connected to the lower plate, and a lower top plate rotatably connected to the surface of the support rod.

[0006] Preferably, a limit frame is fixed at the lower end of the lower plate, and the lower top plate is slidably connected to the limit frame.

[0007] Preferably, a lower rod is fixed to the lower end of the lower plate, and a stepped plate is rotatably connected to the surface of the lower rod.

[0008] Preferably, a spring is fixed in the middle of the step plate, a pedal is fixed at one end of the support rod, and a guide block is fixed on the surface of the support rod.

[0009] Preferably, a positioning plate is fixed to the lower end of the lower plate, a locking plate is slidably connected to the surface of the positioning plate, and a push plate is fixed to the other end of the locking plate opposite to the stepped plate.

[0010] Preferably, a drawer is slidably connected to the surface of the upper plate, and a push rod is fixed to the side of the upper plate.

[0011] Compared with related technologies, the auxiliary device provided by this utility model has the following beneficial effects:

[0012] This invention uses a support rod to lift the auxiliary device, thus raising the casters off the ground and quickly fixing the device in place, preventing it from being pushed. Compared to existing methods that use locking plates on the two casters to fix the auxiliary device, the support rod method is faster and more convenient, accelerating the preparation speed for clinical emergency care and gaining necessary time.

[0018] Implementation examples, by Figure 1-4 The present invention includes an auxiliary device comprising a lower plate 4, a middle rod 3 fixed to the upper end of the lower plate 4, an upper plate 1 fixed to the upper end of the middle rod 3, a positioning rod 9 fixed to the lower end of the lower plate 4, a support rod 6 rotatably connected to the surface of the positioning rod 9, an upper top plate 8 rotatably connected to one end of the support rod 6, the upper end of the upper top plate 8 rotatably connected to the lower plate 4, and a lower top plate 10 rotatably connected to the surface of the support rod 6.

[0019] The lower end of the lower plate 4 is fixed with a limit frame 11, and the lower top plate 10 is slidably connected to the limit frame 11.

[0020] The lower end of the lower plate 4 is fixed with a lower rod 12, and a step plate 16 is rotatably connected to the surface of the lower rod 12.

[0021] A spring 17 is fixed in the middle of the step plate 16, a footboard 5 is fixed at one end of the support rod 6, and a guide block 18 is fixed on the surface of the support rod 6.

[0022] A positioning plate 15 is fixed to the lower end of the lower plate 4. A locking plate 13 is slidably connected to the surface of the positioning plate 15. A push plate 14 is fixed to the other end of the locking plate 13 relative to the step plate 16.

[0023] A drawer 2 is slidably connected to the surface of the upper plate 1, and a push rod 7 is fixed to the side of the upper plate 1.

[0024] The nurse places the necessary medical supplies on the upper plate 1 and the less frequently used supplies on the lower plate 4. Pushing the push rod 7 moves the auxiliary device to the patient's bedside. Stepping down on the pedal 5 causes the pedal 5 to rotate relative to the positioning rod 9, which in turn causes the support rod 6 to move the upper top plate 8 upwards, supporting the lower plate 4. The lower top plate 10 moves downwards, raising the support rod 6. Simultaneously, the support rod 6 presses down on the step plate 16, causing the step plate 16 to rotate relative to the lower rod 12. The spring 17 stretches, causing the guide block 18 to push away the step plate 16. After the guide block 18 disengages from the step plate 16, the spring 17 pulls the step plate 16 back, fixing the position of the support rod 6. Because the locking plate 13 restricts the position of the step plate 16, it cannot rotate upwards, thus supporting the entire auxiliary device.
