BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be explained in detail in combination with the drawings and specific embodiments:

[0010] Figure 1 This is a schematic diagram of the xenon lamp fixing structure of this utility model;

[0011] Figure 2 This is a schematic diagram of the xenon lamp fixing structure of this utility model applied to a fluorescence detector. Detailed Implementation

[0012] The present invention provides a xenon lamp fixing structure as follows: Figures 1-2 As shown, it mainly includes a xenon lamp 14 and a light source box 13. The light source box mainly includes a base plate 10, a top plate 15, and two side plates 12. Figure 1 , 2 The left side panel is hidden, and only the right side panel and front panel 11 are shown, forming a box-like structure. A xenon lamp holder 16 is mounted on the bottom plate 10 inside the box. The top plate 15 has a circular window 19 for inserting a xenon lamp 14. The xenon lamp 14 can extend through the window 19 and is threaded onto the xenon lamp holder 16 at its bottom, while the upper end of the xenon lamp 14 protrudes from the window. A pair of window baffles 17 are also located on the top plate 15. Each baffle 17 has a semi-circular hole, which, when combined, forms a clamping hole for fixing the upper end of the xenon lamp 14. The baffles 17 also have oblong holes 18 for adjusting the position on the top plate 15, used for mounting and positioning xenon lamps 14 of different sizes.

[0013] Therefore, when using it, loosen the bolts on the waist-shaped hole 18 (not shown in the figure), move the window baffles 17 to both sides to expose the window 19, select the xenon lamp 14 of the required specifications, extend it into the light source box through the window and install it on the xenon lamp holder 16, then move the two window baffles 17 relative to each other so that the clamping holes can just clamp the exposed end of the positioning xenon lamp 14, which serves to block the light of the window and fix the xenon lamp 14, and then tighten the bolts on the waist-shaped hole 18 to fix it to the top plate 15.

[0014] In addition, a light-emitting circular hole 20 is opened on the front plate, and a conical light-shielding tube 21 is also provided at the front end of the front plate 11. The diameter of the end of the light-shielding tube 21 is the same as that of the light-emitting circular hole 20 of the front plate 11 and is connected to it. The diameter gradually decreases from back to front. The light emitted by the xenon lamp 14 is reflected by the concave lens 2 located at the rear of the light source box 13 and then exits the light source box 13 through the light-emitting circular hole 20. It then passes through the light-shielding tube 21 and enters the subsequent detection structure of the fluorescence detector 1.

[0015] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
