[0028] Such as Figures 1 - 5As shown in the figure, an embodiment of the present utility model provides a fixed mechanism for a vomitoxin fluorescence quantitative detection card, including: a mounting plate 1, two groups of symmetric limiting angles 2 are fixed at the upper end of the mounting plate 1, and both groups of limiting angles 2 include upper plates 21. The upper plate 21 is a right triangle with a folded angle on the hypotenuse. On one side of one group of right-angled sides of the upper plate 21, a side plate 22 is fixed, and on one side of the other group of right-angled sides of the upper plate 21, an end plate 23 is fixed. At the end of the end plate 23 away from the side plate 22, there is an inclined bend 24. A vomitoxin fluorescence quantitative detection card body is arranged between the two groups of limiting angles 2. A limiting hole 6 is penetrated through the mounting plate 1, and a popping-up structure 5 is arranged inside the limiting hole 6. The popping-up structure 5 includes a cylindrical rod 51. At both ends of the outer side wall of the cylindrical rod 51, two groups of rectangular plates 53 are respectively fixed. At the upper end of the cylindrical rod 51, a convex block 52 is fixed. At both ends of the cylindrical rod 51, convex hemispheres 54 are fixed. The limiting hole 6 is divided into two groups of symmetrically arranged rectangular holes 61 and a strip-shaped hole 62. The two ends of the strip-shaped hole 62 are respectively penetrated and communicated with the two ends of the two groups of rectangular holes 61. On the side where the rectangular hole 61 and the strip-shaped hole 62 are connected, there is an arc wall 63 adapted to the rotation track curve of the cylindrical rod 51. On the side of the two rectangular plates 53 away from the cylindrical rod 51, they are respectively fixedly connected to the bottom side walls of the two groups of rectangular holes 61. The cylindrical rod 51 is located at the upper end of the strip-shaped hole 62. The side of the two rectangular plates 53 connected to the rectangular hole 61 has elasticity, and the other side of the two rectangular plates 53 is inclined upward. The upper part of the cylindrical rod 51 extends out of the strip-shaped hole 62 and abuts against one side of the vomitoxin fluorescence quantitative detection card body.

[0029] By pressing the convex block 52, the cylindrical rod 51 slides downward along the arc wall 63, and the ends of the two rectangular plates 53 connected to the mounting plate 1 generate elastic deformation. The popping-up structure 5 rotates downward with the connection of the rectangular plate 53 and the rectangular hole 61 as the axis until the cylindrical rod 51 and the convex block 52 completely enter the strip-shaped hole 62. Then, the vomitoxin fluorescence quantitative detection card body is slid into the limiting angle along the two side end plates 23. The folded angle on the hypotenuse of the upper plate 21 can not block the upper test paper hole when fixing the vomitoxin fluorescence quantitative detection card body. The inclined bends 24 on both sides can increase the entry distance between the two end plates 23, enabling the vomitoxin fluorescence quantitative detection card body to quickly enter 2 until one side of the vomitoxin fluorescence quantitative detection card body abuts against the two side plates 22. At this time, the other side of the vomitoxin fluorescence quantitative detection card body is located at the edge position of the strip-shaped hole 62. At this time, the convex block 52 is separated from the abutment of the vomitoxin fluorescence quantitative detection card body. At this time, one end of the rectangular plate 53 recovers elastic deformation, causing the entire popping-up structure 5 to rotate upward with the connection of the rectangular plate 53 and the rectangular hole 61 as the axis. The cylindrical rod 51 slides along the side wall of the arc wall 63 until it exposes the upper end of the strip-shaped hole 62. The cylindrical rod 51 and the convex block 52 abut against the other side of the vomitoxin fluorescence quantitative detection card body, playing a role in quickly fixing the vomitoxin fluorescence quantitative detection card body, and the operation is relatively simple.

[0030] As Figures 1 - 5 shown, in this embodiment, an L-shaped plate 3 is fixedly connected to the upper end of the mounting plate 1 and on one side of a set of limiting angles 2. A funnel-shaped locator 4 is fixedly penetrated through the upper end of the L-shaped plate 3. The upper end of the vomitoxin fluorescence quantitative detection card body is provided with a test paper hole and a result display hole. The lower end of the funnel-shaped locator 4 is directly opposite to the upper end of the test paper hole. The diameter of the lower end opening circle of the funnel-shaped locator 4 is equal to the diameter of the test paper hole. Circular chamfers are provided at the edge positions of the limiting angles 2. The two end plates 23 are respectively in contact with both ends of the vomitoxin fluorescence quantitative detection card body, and the two side plates 22 are both in contact with one side of the vomitoxin fluorescence quantitative detection card body. The upper end of the convex block 52 is ellipsoidal. The diameter of the cylindrical rod 51 is equal to the diameter of the convex hemisphere 54, and the surfaces of the two convex hemispheres 54 are respectively in contact with the inner walls of the two rectangular holes 61. The length of the rectangular hole 61 is equal to the sum of the length of the rectangular plate 53 and the radii of the two convex hemispheres 54. The width of the strip-shaped hole 62 is equal to the diameter of the cylindrical rod 51. The two convex hemispheres 54 can play a role in reducing the contact area with the side wall of the rectangular hole 61 to facilitate sliding. By dropping a test solution into the funnel-shaped locator 4 on the L-shaped plate 3, good positioning can be achieved, and the test solution can be accurately added into the test paper hole.

[0031] According to the technical solution provided by the present utility model, when it is necessary to fix the vomitoxin fluorescence quantitative detection card body, first, by pressing the convex block 52, the cylindrical rod 51 slides downward along the arc wall 63. One end of the two rectangular plates 53 connected to the mounting plate 1 generates elastic deformation, and the elastic structure 5 rotates downward with the connection between the rectangular plate 53 and the rectangular hole 61 as the axis until the cylindrical rod 51 and the convex block 52 completely enter the interior of the strip-shaped hole 62. Then, the vomitoxin fluorescence quantitative detection card body is slid into the limiting angle along the two side end plates 23. The fold angle of the hypotenuse of the upper plate 21 can not block the upper test paper hole when fixing the vomitoxin fluorescence quantitative detection card body. The two inclined bending parts 24 on both sides can increase the entry distance between the two end plates 23, so that the vomitoxin fluorescence quantitative detection card body can quickly enter 2 until one side of the vomitoxin fluorescence quantitative detection card body abuts against the two side plates 22. At this time, the other side of the vomitoxin fluorescence quantitative detection card body is located at the edge position of the strip-shaped hole 62. At this time, the convex block 52 is disengaged from the abutment of the vomitoxin fluorescence quantitative detection card body. At this time, one end of the rectangular plate 53 recovers elastic deformation, so that the entire elastic structure 5 rotates upward with the connection between the rectangular plate 53 and the rectangular hole 61 as the axis, and the cylindrical rod 51 slides along the side wall of the arc wall 63 until it exposes the upper end of the strip-shaped hole 62. The two convex hemispheres 54 can play a role in reducing the contact area with the side wall of the rectangular hole 61 to facilitate sliding. The cylindrical rod 51 and the convex block 52 abut against the other side of the vomitoxin fluorescence quantitative detection card body, playing a role in quickly fixing the vomitoxin fluorescence quantitative detection card body. The operation is relatively simple. Then, by dropping a test solution into the funnel-shaped locator 4 on the L-shaped plate 3, good positioning can be achieved, and the test solution can be accurately added into the test paper hole.

In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model even without the description of these details.

[0033] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
