DETAILED DESCRIPTION

[0027] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-6 , the utility model is further introduced in detail.

[0028] In each embodiment of the present invention, for the convenience of description and understanding, the length direction of the mounting frame 1 is referred to as the length direction, the direction perpendicular to the length direction on the horizontal plane is referred to as the width direction, and the direction of gravity is referred to as the vertical direction, that is, the length direction, width direction and vertical direction constitute a three-dimensional rectangular coordinate system.

[0029] An embodiment of the present utility model provides a shelf, including a mounting frame 1 fixedly mounted on a wall, a plurality of disinfection and sterilization parts 2 being detachably mounted on the mounting frame 1, a fixing part 3 being rotatably mounted on the disinfection and sterilization part 2, the fixing part 3 being used to fix a test instrument 5, and a limiting part 4 being further provided on the fixing part 3, when the fixing part 3 rotates half a circle with the test instrument 5, the limiting part 4 limits the fixing part 3, and when the disinfection and sterilization part 2 completes the disinfection and sterilization process, the limiting part 4 releases the restriction of the fixing part 3.

[0030] Specifically, the mounting frame 1 can be fixedly mounted on the wall by gluing or bolting. In this embodiment, the mounting frame 1 is mounted on the wall by gluing, wherein a plurality of disinfection and sterilization parts 2 are arranged at intervals on the mounting frame 1 along the length direction. In this embodiment, the test equipment 5 can be selected from test tube brushes, beaker brushes, bottle brushes, round-bottom bottle brushes and the like. In the drawings and descriptions of the present invention, test tube brushes are taken as examples. However, it is obvious that the test equipment 5 is not limited to brush-type equipment. It is only necessary that the equipment has a handle and a head, and the head needs to be disinfected after use. The existing test equipment 5 is directly hung on the mounting frame 1 after use. At this time, the brush head of the test equipment 5 is located in the disinfection and sterilization part 2, and the brush handle of the test equipment 5 is located below the disinfection and sterilization part 2. The test equipment 5 is then sterilized and disinfected by the disinfection and sterilization part 2. However, the placement status of the multiple test equipment 5 on the mounting frame 1 is consistent, so that the user cannot distinguish which test equipment 5 has been sterilized. Therefore, when using, it is easy to mistakenly take the test equipment 5 that has not been sterilized and use it, which poses a certain oral hygiene risk.

[0031] In order to solve the above problems, in this embodiment, a fixing part 3 is rotatably installed on the disinfection and sterilization part 2, and the fixing part 3 is used to fix the test equipment 5, wherein the fixing part 3 can adopt a common fixing method (such as clamping with a clamp), wherein the limiting part 4 can adopt multiple driving motors, and multiple driving motors correspond to multiple fixing parts 3, and the output end of the driving motor is connected to the fixing part 3. When the test equipment 5 is used, the user places the test equipment 5 on the fixing part 3, and the corresponding limiting part 4 drives the fixing part 3 to rotate half a circle, so that the test equipment 5 to be disinfected and sterilized is In the inverted state mode (the inverted state is that the brush head of the test equipment 5 is located in the fixed part 3, and the brush handle of the test equipment 5 is located above the brush head), after the disinfection and sterilization part 2 completes the sterilization treatment of the test equipment 5, the limiting part 4 drives the fixed part 3 to rotate half a circle in the opposite direction, so that the test equipment 5 is restored to the state where the brush handle is located below the brush head, and the test equipment 5 includes a brush head and a brush handle. In the initial state, the brush head of the test equipment 5 is located in the fixed part 3, and the brush handle of the test equipment 5 is located below the brush head; when the fixed part 3 rotates half a circle, the brush handle of the test equipment 5 is located above the brush head.

[0032] Therefore, the test equipment 5 on the mounting frame 1 has two placement states:

[0033] The first state is when the test equipment 5 has been disinfected, and the brush head of the test equipment 5 is located above the brush handle;

[0034] The second is a state in which the test equipment 5 is being disinfected, and the brush head of the test equipment 5 is located below the brush handle;

[0035] Since the state of the test equipment 5 during disinfection is different from the state of placement after disinfection, it is possible to simply distinguish whether the test equipment 5 has been disinfected by observing the placement state of the test equipment 5, which can greatly avoid the user from mistakenly using the unsterilized test equipment 5.

[0036] In this embodiment, preferably, the disinfection and sterilization part 2 includes an ultraviolet lamp 21 and two groups of side panels 22, the two groups of side panels 22 are fixedly mounted on the mounting frame 1, the two groups of side panels 22 are spaced apart, the ultraviolet lamp 21 is located between the two groups of side panels 22, the fixing part 3 includes a fixing frame 31, two groups of clamping blocks 32 are arranged inside the fixing frame 31, the two groups of clamping blocks 32 are used to clamp and fix the test equipment 5, and two rotating shafts 33 are symmetrically arranged on the outside of the fixing frame 31, the two rotating shafts 33 correspond to the two side panels 22 respectively, the rotating shaft 33 is rotatably connected to the corresponding side panels 22, and the rotating shaft 33 is connected to the corresponding side panels 22 by a torsion spring 34, which is used to drive the torsion after rotation The spring 34 resets, and the clamping block 32 includes a shell 321. The shell 321 is arranged horizontally. A splint 323 is connected to the shell 321 through a spring 322. The splint 323 is close to the end of the test equipment 5 and is provided with a slot 324 that matches the surface of the test equipment 5. The limiting part 4 includes a limiting electromagnet 41 and an adsorption block 42. The limiting electromagnet 41 is installed on the disinfection and sterilization part 2. The limiting electromagnet 41 is electrically connected to the disinfection and sterilization part 2. The adsorption block 42 is installed on the side of the fixing frame 31 away from the mounting frame 1. In the initial state, the limiting electromagnet 41 and the adsorption block 42 are spaced apart. After the fixing part 3 rotates half a circle, the adsorption block 42 is abutted against the limiting electromagnet 41.

[0037] Specifically, the two groups of side panels 22 are placed vertically, and the two groups of side panels 22 are arranged vertically between the mounting frame 1, the two groups of clamping blocks 32 are arranged horizontally, and the two groups of clamping blocks 32 are arranged at intervals along the length direction, and the axial direction of the rotating shaft 33 is parallel to the length direction of the mounting frame 1. When the test equipment 5 has completed disinfection, the torsion spring 34 is in a stress-free state. When the test equipment 5 is being disinfected, the torsion spring 34 accumulates elastic potential energy based on the rotation of the fixing frame 31. Among them, the limiting electromagnet 41 is electrically connected to the disinfection and sterilization part 2. When the disinfection and sterilization part 2 starts working, the limiting electromagnet 41 is energized and has magnetism. When the disinfection and sterilization part 2 stops working, the limiting electromagnet 41 is de-energized.

[0038] In this embodiment, the placement process of the test equipment 5 is as follows:

[0039] First, the used test equipment 5 is manually placed in the fixing frame 31. At this time, the brush head is located above the brush handle. The two clamping plates 323 on the fixing frame 31 clamp the brush handle of the test equipment 5 under the action of the spring 322 (at this time, the two clamping plates 323 clamp the side of the brush handle close to the brush head). The bristles on the brush head are located on the side away from the mounting frame 1. The placement process of the test equipment 5 is completed.

[0040] Subsequently, the fixing frame 31 is manually driven to rotate, and the fixing frame 31 rotates half a circle (i.e., 180°) on the side plate 22 through the rotating shaft 33 until the test equipment 5 is in an inverted state (i.e., the brush handle of the test equipment 5 is located above the brush head). When the rotating shaft 33 rotates, the torsion spring 34 accumulates elastic potential energy. After the test equipment 5 rotates half a circle, the adsorption block 42 abuts against the limiting electromagnet 41, and the bristles on the brush head of the test equipment 5 are facing the ultraviolet lamp 21 of the disinfection and sterilization part 2 (improving the disinfection effect). Subsequently, the ultraviolet lamp 21 starts to energize to disinfect the bristles, and because the ultraviolet lamp 21 is energized, the limiting electromagnet 41 also has magnetism due to the power supply, and the limiting electromagnet 41 adsorbs the adsorption block 42, preventing the torsion spring 34 from releasing the accumulated elastic potential energy.

[0041] Finally, when the ultraviolet lamp 21 completes the disinfection of the bristles, the ultraviolet lamp 21 is powered off, the limiting electromagnet 41 is also powered off, the limiting electromagnet 41 loses its magnetism, the torsion spring 34 releases the accumulated elastic potential energy, the torsion spring 34 drives the rotating shaft 33 to reverse, the rotating shaft 33 drives the fixing frame 31 to reverse synchronously, and the fixing frame 31 drives the test equipment 5 to return to its initial state. At this time, the brush handle of the test equipment 5 is located below the brush head.

[0042] Obviously, the state of the test equipment 5 during disinfection is different from the state after disinfection. Therefore, the user can simply distinguish whether the test equipment 5 has been disinfected by observing the placement state of the test equipment 5, which can greatly avoid the user from mistakenly using the unsterilized test equipment 5.

[0043] Preferably, a rubber layer 325 is provided in the notch 324 of the clamping plate 323 , wherein the provision of the rubber layer 325 enables the clamping plate 323 to have a greater friction force when clamping the test equipment 5 , so that the test equipment 5 is clamped more firmly.

[0044] In addition, hooks 6 are provided on both sides of the mounting frame 1. The provision of the hooks 6 allows the mounting frame 1 to hang more objects, thereby improving the functionality of the mounting frame 1.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
