[0035] With reference to Figure 2 And Figure 3The rotating center shaft of the ratchet wheel 34 is fixedly connected with the telescopic pedal 33. When the telescopic pedal 33 is pressed downward, the ratchet wheel 34 is synchronously rotated. One end of the limiting spring 36 is fixedly connected with the outer wall of the wedge block 37, and the other end of the limiting spring 36 is fixedly connected with the inner wall of the fixed block 35. The limiting spring 36 is used for automatically resetting the position of the wedge block 37 after the arc surface of the wedge block 37 is extruded and moved by the arc surface of the ratchet wheel 34, so that the back surface of the wedge block 37 is in contact with the back surface of the ratchet wheel 34, thereby preventing the reverse rotation of the ratchet wheel 34, so that the telescopic pedal 33 and the ratchet wheel 34 return to the initial position, and the wedge block 37 can be manually rotated, so that the sliding column 32 is lowered by gravity, and the telescopic pedal 33 and the ratchet wheel 34 return to the initial position. The outer side of the fixed column 31 is rotatably connected with the ratchet wheel 34. The outer side wall of the fixed column 31 is fixedly connected with the fixed block 35. The inner wall of the fixed block 35 is elastically connected with the wedge block 37 through the limiting spring 36. The wedge block 37 is slidably connected with the inner wall of the fixed block 35. The outer wall of the ratchet wheel 34 is provided with a plurality of tooth blocks. The outer wall of the wedge block 37 is in contact with the tooth blocks of the ratchet wheel 34. The telescopic pedal 33 drives the ratchet wheel 34 to rotate in one direction and push the sliding column 32 upward, and cannot rotate in the reverse direction.

[0036] With reference to Figure 4 and Figure 5 The limiting assembly 6 comprises a limiting ball 61 which is slidably connected with the inner wall of the bottom end of the placing box 4. The surface of the supporting plate 5 is provided with a ball groove. The outer wall of the bottom end of the limiting ball 61 is in contact with the inner wall of the ball groove. The limiting ball 61 is always elastically supported by the reset spring 62 when the limiting ball 61 is in contact with the ball groove, so that the placing box 4 is not rotated on the top end of the supporting plate 5 without external force. The limiting ball 61 is elastically connected with the inner wall of the bottom end of the placing box 4 through the reset spring 62. One end of the reset spring 62 is fixedly connected with the top end of the inner wall of the placing box 4. The other end of the reset spring 62 is fixedly connected with the outer wall of the limiting ball 61. The reset spring 62 is used for automatically resetting the position of the ball surface of the limiting ball 61 after the ball surface of the limiting ball 61 is extruded and moved by the inner wall of the ball groove of the supporting plate 5.

[0037] Working principle: when the placing box 4 and the supporting plate 5 need to be raised to adapt to a higher sickbed for dressing operation, the nurse steps on the pedal end of the telescopic pedal 33. Since the telescopic pedal 33 is a special structure composed of two groups of rod bodies, when it is pressed, it will make a lever-like movement around the hinge point, and the other end will push the sliding column 32 to slide upward in the inner wall of the fixed column 31. The upward movement of the sliding column 32 drives the supporting plate 5 and the placing box 4 placed on the supporting plate 5 to move upward synchronously, so that the medicine and other articles placed in the placing box 4 are raised to a suitable height, which is convenient for the nurse to take and dress,

[0038] Meanwhile, the telescopic pedal 33 drives the ratchet wheel 34 to rotate synchronously during the pressing down process, and the arc surface of the tooth block of the ratchet wheel 34 extrudes the arc surface of the wedge block 37 when the ratchet wheel 34 rotates, so that the wedge block 37 slides inward in the inner wall of the fixed block 35 and compresses the limiting spring 36; when the tooth block of the ratchet wheel 34 rotates past the wedge block 37, the wedge block 37 is reset under the elastic restoring force of the limiting spring 36, the back surface of the wedge block 37 contacts the back surface of the tooth block of the ratchet wheel 34, the reverse rotation of the ratchet wheel 34 is limited, and then the position of the telescopic pedal 33, the sliding column 32 and the placing box 4 after rising is fixed, so that the device can be stably maintained at the required height during the dressing change process and cannot be accidentally lowered due to external force and other factors; when the dressing change is completed and it is required to lower the placing box 4 and the supporting plate 5 to the initial position or adjust to a lower position for the next use, the nurse can manually move the wedge block 37 to slide inward against the elastic force of the limiting spring 36, so that the wedge block 37 is separated from the contact with the back surface of the tooth block of the ratchet wheel 34, the limitation on the reverse rotation of the ratchet wheel 34 is removed, at this time, the placing box 4, the supporting plate 5 and the sliding column 32 gradually lower under the action of their own gravity, drive the telescopic pedal 33 and the ratchet wheel 34 to synchronously return to the initial position, and the height adjustment is completed, so that the movement of the device and the subsequent reuse are facilitated.

[0039] In the normal state, the placing box 4 is placed at the top end of the supporting plate 5, the bottom end outer wall of the limiting ball 61 is in close contact with the inner wall of the ball groove on the surface of the supporting plate 5 under the elastic support of the reset spring 62, at this time, the elastic force of the reset spring 62 makes the limiting ball 61 remain in this contact position, the arbitrary rotation of the placing box 4 relative to the supporting plate 5 is limited, the placing box 4 can be stably placed on the supporting plate 5 without being affected by external force (such as the nurse not actively operating the rotation), and the situation that the instruments and medicines in the placing box 4 are displaced or fall off due to accidental shaking and the like is avoided; when the nurse needs to rotate the placing box 4 to rotate around the center of the left surface of the supporting plate 5 to open and adjust to the upper side of the sickbed for convenient dressing operation, external force is applied to rotate the placing box 4, the ball surface of the limiting ball 61 is extruded by the inner wall of the ball groove on the surface of the supporting plate 5 during the rotation of the placing box 4, so that the limiting ball 61 slides upward in the bottom end inner wall of the placing box 4 and compresses the reset spring 62; when the placing box 4 is rotated to the appropriate position, the external force disappears, the limiting ball 61 is reset under the elastic restoring force of the reset spring 62 and is in contact with the inner wall of the ball groove again, so that the placing box 4 is stably placed at the new position and the nurse can perform the dressing operation.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement and the like within the spirit and principles of the present application should be included in the protection scope of the present application.
