[0023] Please continue to refer toFigure 3 、 Figure 4 and Figure 5 In this embodiment, in order to achieve the sliding connection between the sliding assembly 42 and the slide rail 41, the following specific arrangement is made. Specifically, the slide rail 41 comprises a fixed plate 411 fixedly connected with the rear side wall 21, a top plate 412 and a bottom plate 413 fixedly connected with the upper and lower ends of the fixed plate 411, and an upper baffle 414 fixedly connected with the front lower side of the top plate 412 and a lower baffle 415 fixedly connected with the front upper side of the bottom plate 413. The sliding assembly 42 is slidingly assembled in a sliding space enclosed by the fixed plate 411, the top plate 412, the bottom plate 413, the upper baffle 414 and the lower baffle 415. The upper baffle 414 and the lower baffle 415 are arranged in a spaced manner to form an opening for the storage frame 43 to extend out. The sliding assembly 42 is covered in the fixed plate 411, the top plate 412, the bottom plate 413, the upper baffle 414 and the lower baffle 415, so that the sliding assembly 42 can only move in the length direction of the slide rail 41. In this way, the sliding connection between the sliding assembly 42 and the slide rail 41 is achieved.

[0024] In order to fix the sliding assembly 42 at different positions on the slide rail 41, the sliding assembly 42 is designed as an elastic telescopic structure in the embodiment, and the specific structure of the sliding assembly 42 comprises a first sliding block 421 and a second sliding block 422 arranged above the first sliding block 421 and elastically connected with the first sliding block 421. The elastic connection between the first sliding block 421 and the second sliding block 422 can push the first sliding block 421 and the second sliding block 422 to the upper side and the lower side respectively. Specifically, a spring 423 is arranged between the first sliding block 421 and the second sliding block 422, and the two ends of the spring 423 are fixedly connected with the opposite sides of the first sliding block 421 and the second sliding block 422 respectively. The first sliding block 421 and the second sliding block 422 can be telescoped in the vertical direction under the action of the spring 423 to make the first sliding block 421 and the second sliding block 422 abut on the inner surfaces of the top plate 412 and the bottom plate 413 of the slide rail 41 respectively. When the sliding assembly 42 is installed into the slide rail 41, the first sliding block 421 and the second sliding block 422 are simultaneously extruded to the middle to overcome the elastic force of the spring 423, and the two are relatively slid to reduce the height. When the height of the first sliding block 421 and the second sliding block 422 after contraction is less than the distance between the top plate 412 and the bottom plate 413, the first sliding block 421 and the second sliding block 422 are put into the slide rail 41, and then the first sliding block 421 and the second sliding block 422 are released, so that the two are respectively stretched to the upper side and the lower side under the elastic force of the spring 423, and the first sliding block 421 and the second sliding block 422 are respectively abutted on the top plate 412 and the bottom plate 413. In this way, the elastic force of the spring 423 can increase the friction between the sliding assembly 42 and the slide rail 41, so that the sliding assembly 42 cannot easily slide in the slide rail 41. When the sliding assembly 42 needs to be moved, only a certain force is applied to the first sliding block 421 in the contraction direction of the spring 423 to make the spring 423 contract. At this time, the bottom surface of the first sliding block 421 is separated from the inner surface of the bottom plate 413, and then the sliding can be performed.

[0025] In order to keep the liquid container in a more stable state when the liquid medicine is configured, the sliding assembly 42 needs to be fixed in the slide rail 41 so as to no longer slide left and right. The structure of the storage frame 43 is specially arranged in the embodiment, specifically, a supporting ring 431 for supporting the liquid container is arranged in the storage frame 43, and a connecting piece 432 connected to the side of the supporting ring 431 and connected with the first sliding block 421 is arranged, the lower side of the connecting piece 432 abuts against the top of the lower baffle 412, and at the same time, a plurality of limiting grooves 4151 are arranged on the top of the lower baffle 415 along the length direction of the slide rail 41, and the connecting piece 432 can be clamped into any one of the limiting grooves 4151 to limit the left and right sliding of the first sliding block 421. When the sliding assembly 42 slides in the slide rail 41, when the connecting piece 432 slides into any one of the limiting grooves 4151, the two side walls of the limiting groove 4151 are wrapped on the two side walls of the connecting piece 432, so as to limit the connecting piece 432 in the limiting groove 4151, at this time, the sliding assembly 42 also cannot continue to slide, at this time, the position of the liquid container is kept fixed. If the position of the sliding assembly 42 needs to be moved, the connecting piece 432 only needs to be lifted from the limiting groove 4151, so that the bottom surface of the connecting piece 432 is higher than the top of the limiting groove 4151, and then it can be slid. In the embodiment, the first sliding block 421, the connecting piece 432 and the storage frame 43 are integrally formed, and the integrally formed structure is more convenient for overall installation, and the manufacturing process is also simpler.

[0026] In order to prevent the first sliding block 421 and the second sliding block 422 from deflecting when they are stretched and contracted under the action of the spring 423, a sliding sleeve 4221 wrapped on the outside of the first sliding block 421 is formed on the bottom of the second sliding block 422, the inner wall of the sliding sleeve 4221 is attached to the outer side wall of the first sliding block 421, and the second sliding block 422 cannot deflect when it is stretched and contracted up and down, but can only move in the vertical direction through the sliding sleeve 4221. One side of the sliding sleeve 4221 is provided with a bolt 42211 penetrating in and out, and at the same time, the first sliding block 421 is formed with a sliding groove 4211 for the bolt 42211 to move in the vertical direction on one side relative to the bolt 42211. At the same time, in order to make the sliding sleeve 4221 more balanced when sliding, in other embodiments, the bolt 42211 can also be arranged on the opposite two sides of the sliding sleeve 4221. When the second sliding block 422 is stretched in the vertical direction, the bolt 42211 moves in the sliding groove 4211 towards the top of the sliding groove 4211, and when the bolt 42211 abuts against the top of the sliding groove 4211, the second sliding block 422 will be limited to move, so as to prevent the sliding sleeve 4221 from being separated from the first sliding block 421.

[0027] In order to make the sliding assembly 42 slide more smoothly in the sliding process of the slide rail 41, in the embodiment, a plurality of rolling balls 4222 are rotatably connected to the upper end of the second sliding block 422, and the plurality of rolling balls 4222 can abut against the inner surface of the top plate 412. The rolling balls 4222 are rotated to reduce the friction between the second sliding block 422 and the top plate 412, so that the sliding is more smooth. In order to make the sliding assembly 42 more balanced in the sliding process, in the embodiment, the number of the plurality of rolling balls 4222 is four, and the four rolling balls 4222 are distributed in a rectangular shape on the upper surface of the second sliding block 422. Thus, the second sliding block 422 is in contact with the top plate 412 through the four rolling balls 4222 and can be uniformly stressed in four directions, so as to avoid the axial inclination of the sliding assembly 42, and make the sliding assembly 42 more balanced in the sliding process. In order to realize the rotatable connection between the rolling balls 4222 and the second sliding block 422, a limiting shell 4224 is arranged above the second sliding block 422, the plurality of rolling balls 4222 are arranged between the upper end of the second sliding block 422 and the limiting shell 4224, and a limiting hole 42241 corresponding to each rolling ball 4222 is formed in the limiting shell 4224. The diameter of the limiting hole 42241 is smaller than the diameter of the rolling ball 4222. Each rolling ball 4222 protrudes from the upper surface of the limiting shell 4224 through the corresponding limiting hole 42241. Since the diameter of the limiting hole 42241 is smaller than the diameter of the rolling ball 4222, the rolling ball 4222 cannot pass through the limiting hole 42241. In addition, the limiting hole 42241 can limit the position of the rolling ball 4222, so as to limit the movement of the rolling ball 4222 relative to the second sliding block 422, so as to realize the rotatable connection between the rolling ball 4222 and the second sliding block 422. At the same time, in order to better fit the rolling ball 4222 and the limiting hole 42241, the inner circumferential surface of the limiting hole 42241 is a spherical inclined surface matched with the outer surface of the rolling ball 4222. In order to facilitate the installation of the rolling ball 4222, four recesses 4223 are formed in a rectangular shape on the upper surface of the second sliding block 422. When installing the rolling ball 4222, the four rolling balls 4222 are respectively placed in the four recesses 4223 to preliminarily limit the rolling ball 4222, so as to avoid the random sliding of the rolling ball 4222, and facilitate the user to assemble the rolling ball 4222. Then, the limiting shell 4224 is assembled on the second sliding block 422 to complete the installation.

[0028] The above is only an embodiment of the present application, and the well-known specific structures and properties in the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. These will not affect the effect and practicability of the present application.
