[0019] The following specific embodiments, in conjunction with the appendix, demonstrate this approach. Figures 1-4 The technical solution of this utility model will be further described in detail below. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0020] Example:

[0021] like Figures 1-4 As shown, this utility model discloses a technical solution: an infusion nursing frame, including an infusion track 1, an infusion rod 2 at the lower end of the infusion track 1, a hook 3 at the bottom end of the infusion rod 2, a sliding member 4 slidably installed on the infusion track 1, and the infusion rod 2 fixedly installed on the sliding member 4 and extending vertically downward.

[0022] In some embodiments of this utility model, a T-shaped connector 11 is fixedly connected to the upper surface of the infusion track 1. The T-shaped connector 11 has a threaded hole for fasteners to pass through. The infusion track 1 is fixed to the mounting surface by the T-shaped connector 11 and the fasteners.

[0023] See Figure 1 In the illustrated embodiment, the infusion track 1 is configured as a rounded rectangular structure, combined with... Figure 2 The side cross section is an "I" shaped structure, made of aluminum alloy. The sliding part 4 is fitted on the infusion track 1 and can slide along the infusion track 1. Preferably, the sliding part 4 includes a sliding part 41 that matches the cross-sectional shape of the infusion track 1. A pulley 42 is rotatably installed on the side of the sliding part 41 facing the infusion track 1. A groove 12 is opened on the infusion track 1. The pulley 42 is partially disposed in the groove 12 and can roll along the path in the groove 12.

[0024] Specifically, the infusion rod 2 is mounted on the sliding member 4 and slides with the sliding member 4. There are two hooks 3 installed at the bottom of the infusion rod 2. The two hooks 3 are set in a direction perpendicular to the infusion rod 2 to form a structure that can be used to hang the infusion bottle. It can be understood that the number of hooks 3 is not limited to the two mentioned above, and can be increased or decreased according to the actual situation during the production process.

[0025] Specifically, the infusion rod 2 adopts a telescopic boom, the telescopic boom is made of stainless steel material, according to the prior art, the telescopic boom includes an outer rod fixed on the sliding piece 4 and an inner rod inserted into the outer rod, the inner rod can be stretched up and down relative to the outer rod to facilitate adjusting the height of the hook piece 3, this part belongs to the prior art, and the specific telescopic structure will not be described here.

[0026] Specifically, the bottom of the sliding piece 4 is provided with a mounting seat 5 with an open lower end, the top end of the infusion rod 2 has a mounting head 6, one end of the infusion rod 2 provided with the mounting head 6 extends into the mounting seat 5, the mounting seat 5 and the mounting head 6 are both cylindrical in shape, the mounting seat 5 is internally provided with an arc-shaped snap ring 7, and the arc-shaped snap ring 7 is connected with the mounting seat 5 through an elastic steel sheet 8. Specifically, the elastic steel sheet 8 can be bent under pressure, so that the spacing between the arc-shaped snap ring 7 and the inner wall of the mounting seat 5 can be changed. Initially, the elastic steel sheet 8 is not under pressure, the spacing between the two arc-shaped snap rings 7 is smaller than the outer diameter of the mounting head 6, so that when the mounting head 6 is inserted into the mounting seat 5, the two arc-shaped snap rings 7 and the elastic steel sheet 8 are pressed, the elastic steel sheet 8 is deformed and bent under pressure, and the opposite sides of the two arc-shaped snap rings 7 move to the two sides to abut against the surface of the mounting head 6.

[0027] Specifically, a clamping groove 9 matched with the arc-shaped snap ring 7 is formed on the mounting head 6, the clamping groove 9 extends along the circumference of the mounting head 6, and one end of the clamping groove 9 is provided with an access opening 10.

[0028] Specifically, as shown in Figure 3 , the access opening 10 is an arc-shaped groove extending from the inner side of the clamping groove 9 to the outer surface of the mounting head 6. With the above structure, when the mounting head 6 is inserted into the mounting seat 5, the arc-shaped snap ring 7 is pressed to move to the two sides and abut against the surface of the mounting head 6. By rotating and moving the infusion rod 2, the position of the clamping groove 9 corresponds to the position of the arc-shaped snap ring 7, the elastic steel sheet 8 restores the deformation, and the arc-shaped snap ring 7 is clamped in the clamping groove 9. Further, when the access opening 10 is provided as a structure as shown in Figure 3 , the arc-shaped snap ring 7 can be gradually separated from the clamping groove 9 through the access opening 10 by counterclockwise rotating the infusion rod 2.

[0029] Specifically, as shown in Figure 2 , 4 , the top end of the mounting head 6 is provided with a ring-shaped protrusion 13 extending outward, the inner wall of the mounting seat 5 is provided with two arc-shaped clamping plates 14, the two arc-shaped clamping plates 14 are arranged on the two sides of the mounting head 6, the arc-shaped clamping plates 14 are connected with the mounting seat 5 through elastic expansion pieces 15, and the cross-sectional shape of the arc-shaped clamping plate 14 is a circular arc bent to the side of the mounting head 6.

[0030] The infusion nursing frame provided by the utility model, when the mounting head 6 is inserted into the mounting seat 5, the annular protrusion 13 at the top of the mounting head 6 first extrudes the two arc-shaped clamping rings 7 and the two arc-shaped clamping plates 14, and then is clamped through the arc-shaped clamping plate 14, at this time, the mounting head 6 cannot move downwards, but can rotate in the horizontal plane, so as to adjust the position of the clamping groove 9 to make it correspond to the arc-shaped clamping ring 7, and the spacing between the annular protrusion 13 and the clamping groove 9 is greater than the spacing between the arc-shaped clamping plate 14 and the elastic steel sheet 8, the spacing of the excess part is greater than the height of the arc-shaped clamping plate 14, namely, when the annular protrusion 13 is clamped with the arc-shaped clamping plate 14, the positions of the clamping groove 9 and the arc-shaped clamping ring 7 are located in the same horizontal region, when disassembling, the infusion rod 2 needs to be rotated first to make the arc-shaped clamping ring 7 separate from the clamping groove 9, and then a certain size of pulling force downwards is applied to the arc-shaped clamping ring 7, so that the elastic expansion piece 15 and the elastic steel sheet 8 can be extruded, so that the mounting head 6 is separated from the mounting seat 5, and the disassembly of the infusion rod 2 is realized.

[0031] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
