[0012] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0013] Specific implementation method 1: Figure 1-4 As shown, this embodiment describes a lifting device for an infusion stand for nursing in an operating room, comprising an infusion stand 1, two transmission devices 2 and a base 3; the base 3 comprises a housing 31; a plurality of support cylinders 35 are fixedly connected to the inner bottom end of the housing 31; a gear I 33 or a gear II 34 is arranged at the upper end of each support cylinder 35; the gear I 33 is meshed with two gears II 34; the infusion stand 1 is slidably matched with the gear I 33; each transmission device 2 is slidably matched with the corresponding gear II 34. The support cylinder 35 is connected to the corresponding gear I 33 or gear II 34 through a bearing to facilitate the rotation of the gear I 33 and the gear II 34.

[0014] The infusion stand 1 includes a support rod 11, a hanging ring 12, a rectangular rod Ⅰ13 and a round rod Ⅰ14; the upper end of the rectangular rod Ⅰ13 is fixedly connected to the support rod 11; the lower end of the support rod 11 is fixedly connected to a plurality of hanging rings 12; the lower end of the rectangular rod Ⅰ13 is fixedly connected to the round rod Ⅰ14; a spiral groove Ⅰ15 is provided on the outer circumferential surface of the round rod Ⅰ14.

[0015] Each of the transmission devices 2 includes a pedal 21, a connecting rod 22, a rectangular rod II 23 and a round rod II 24; the lower end of the rectangular rod II 23 is fixedly connected to the round rod II 24, the outer circumference of the round rod II 24 is provided with a spiral groove II 25, and the top of the side of the rectangular rod II 23 is fixedly connected to the connecting rod 22; the pedal 21 is fixedly connected to the connecting rod 22; the top of the housing 31 is provided with a plurality of rectangular holes 32; each rectangular hole 32 is slidably matched with the corresponding rectangular rod I 13 or rectangular rod II 23. The rectangular holes 32 are used to limit the rotation of the rectangular rod I 13 and the rectangular rod II 23, thereby limiting the rotation of the round rod I 14 and the round rod II 24.

[0016] The gear I33 and the gear II34 have the same structure; a circular hole 36 is provided at the center of each gear I33 or gear II34, the circular hole 36 on the gear I33 is slidably matched with the round rod I14, and the circular hole 36 on the gear II34 is slidably matched with the round rod II24; a slider 37 is fixedly connected to the inner wall of the circular hole 36 and is slidably matched with the spiral groove I15 or the spiral groove II25.

[0017] The diameter of the gear II 34 is greater than the diameter of the gear I 33. When the gear II 34 rotates 360°, the angle of rotation of the gear I 33 is greater than 360°, so that the support frame 11 can rise faster.

[0018] The spiral grooves II 25 on the round rods II 24 on the two transmission devices 2 rotate in opposite directions. Both gears II 34 mesh with the gear I 33, and the two gears II 34 rotate in the same direction. When the two spiral grooves II 25 rotate in opposite directions, when the pedal 21 on one transmission device 2 moves downward, the pedal 21 on the other transmission device 2 moves upward.

[0019] A limiting ring 39 is fixedly connected to the middle and lower part of the outer circumferential surface of the shell 31 , and a thread is arranged on the outer circumferential surface of the shell 31 . A conical fixing ring 38 is connected to the bottom end of the outer circumferential surface of the shell 31 through a thread; a wheel 310 is also arranged at the bottom end of the shell 31 .

[0020] The conical surface of the fixing ring 38 is located below the pedal 21. When the pedal 21 moves downward and contacts the conical surface outside the fixing ring 38, the upper or lower edge of the round rod Ⅰ14 is close to the round hole 36 on the gear Ⅰ33, and the pedal 21 is restricted by the fixing ring 38 and cannot move downward any further, so as to prevent the round rod Ⅰ14 from being separated from the round hole 36 on the gear Ⅰ33.

[0021] The working principle of the utility model is as follows: when using the device, the infusion stand 1 is moved to a predetermined position by the wheel 310, and then the fixing ring 38 is rotated, and the fixing ring 38 is driven to move downward by the thread on the housing 31 until the lower end of the fixing ring 38 contacts the ground, and an anti-slip pad is provided at the lower end of the fixing ring 38 to prevent the base 3 from moving when the pedal 21 is stepped on;

[0022] When adjusting the height subsequently, when adjusting upward, one of the pedals 21 is stepped down, and the pedal 21 drives the connecting rod 22, rectangular rod II 23 and round rod II 24 connected thereto to move downward, and the spiral groove II 25 on the round rod II 24 drives the slider 37 on the corresponding gear II 34 to rotate, thereby driving the gear II 34 connected thereto to rotate forward, and the gear II 34 meshes with the gear I 33, and the gear I 33 rotates in the opposite direction, and the gear I 33 drives another gear II 34 to rotate forward. Since the spiral grooves II 25 on the two round rods II 24 connected to the two gears II 34 rotate in opposite directions, the other gear II 34 drives the transmission device 2 connected thereto to move upward, and at the same time, when the gear I 33 rotates, the slider 37 on the inner wall of the circular hole 36 thereof slides with the spiral groove I 15 on the round rod I 14, and since the rectangular rod I 13 slides with the rectangular hole 32, its rotation is restricted, thereby driving the round rod I 14 to move upward, so that the round rod I 14 drives the rectangular rod I 13, the support rod 11 and the hanging ring 12 to move upward, and the infusion stand 1 is adjusted upward;

[0023] When adjusting downward, the pedal 21 on the transmission device 2 that moves upward in the above step is stepped on downward, and the pedal 21 drives the round rod II 24 connected thereto to move downward, and then drives the gear II 34 connected thereto to rotate in the opposite direction through the spiral groove II 25, so that the gear I 33 meshing therewith rotates forward, and drives the round rod I 14 to move downward through the cooperation of the slider 37 and the spiral groove I 15, and then drives the rectangular rod I 13, the support rod 11 and the hanging ring 12 to move downward, and the infusion stand 1 is adjusted downward. At the same time, the gear I 33 drives another gear II 34 to rotate in the opposite direction, so that the transmission device 2 that is not stepped on moves upward, and the infusion stand 1 can be adjusted up and down repeatedly in this way;

[0024] When the pedal 21 moves downward and contacts the conical surface outside the fixing ring 38, the upper or lower edge of the round rod Ⅰ14 is close to the round hole 36 on the gear Ⅰ33. The pedal 21 is restricted by the fixing ring 38 and cannot move downward any further, preventing the round rod Ⅰ14 from escaping from the round hole 36 on the gear Ⅰ33.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms of assembly without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
