Purine in the human body turns into uric acid due to oxidation, and excessive uric acid in the human body can cause gout. Therefore, more and more people pay attention to whether the purine content in food exceeds the standard. Therefore, after the food is processed, a liquid chromatograph is usually used to test its samples.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The preferred embodiment of the food purine content detection device provided by the utility model is as follows Figures 1 to 5 As shown: A food purine content detection device includes a liquid chromatograph body 2, a fixing groove 6 is opened at the top of the liquid chromatograph body 2, a clamping component 1 is arranged inside the fixing groove 6, anti-slip feet 3 are fixedly connected at the four corners of the bottom end of the liquid chromatograph body 2, and an anti-slip component 4 is arranged at the middle position of the bottom end of the liquid chromatograph body 2.

[0029] The clamping assembly 1 includes a fixing spring 108, which is fixedly connected to the inner bottom wall of the fixing groove 6 at equal intervals, and the top of the fixing spring 108 is fixedly connected to the placement frame 102, and the middle positions of the two sides of the bottom of the placement frame 102 are fixedly connected to the vibration motor 109, and the two sides of the inner wall of the placement frame 102 are provided with a reserved groove 105, and the reserved groove 105 is movably connected to the inside of the reserved block 110, and the reserved block 110 is fixedly connected to a clamping plate 104 extending to the outside of the reserved groove 105 on one side. A locking bolt 107 extending to the outside of the reserved groove 105 is threadedly connected to one side of the top of 110. After pushing the clamp 104 to slide and fix the liquid storage bottle tightly, the clamp 104 is limited and locked, so that different numbers and specifications of liquid storage bottles can be quickly and firmly clamped and fixed. Then, the vibration motor 109 can be started from time to time to drive the placement rack 102 to slide slightly up and down, so as to achieve oscillation and mixing of the clamped and fixed liquid storage bottles, thereby avoiding precipitation of food samples and affecting the accuracy of subsequent purine content detection.

[0030] In this embodiment, anti-skid grooves 101 are arranged at equal intervals at the bottom of the placement rack 102. The shape of the anti-skid grooves 101 in a top view is rectangular. The rectangular anti-skid grooves 101 are used to improve the friction stability between the bottom of the liquid storage bottle and the inner bottom wall of the placement rack 102.

[0031] In this embodiment, rubber pads 103 are fixedly connected to both ends of the clamping plate 104. The shape of the rubber pads 103 in a top view is arc-shaped. The arc-shaped rubber pads 103 are used to facilitate flexible clamping and fixing of the liquid storage bottle.

[0032] In this embodiment, a placement groove 106 is opened on the inner wall of the placement rack 102 at one end of the reserved groove 105, and the width of the placement groove 106 is greater than the thickness of the reserved block 110. The larger placement groove 106 is used to facilitate the sliding removal or installation of the reserved block 110 from between the placement racks 102, thereby realizing the installation or disassembly of different numbers of splints 104.

[0033] In this embodiment, a sliding structure is formed between the reserved block 110 and the inside of the reserved groove 105. The cross-section of the reserved groove 105 and the reserved block 110 is inverted convex. The sliding between the inverted convex reserved block 110 and the inside of the reserved groove 105 is utilized to improve the smoothness of the back and forth sliding of the splint 104.

[0034] In this embodiment, slide grooves 5 are opened on both sides of the inner wall of the fixed groove 6, and sliders 7 that slide with the inside of the slide grooves 5 are fixedly connected on both sides of the placement rack 102. The sliding of the sliders 7 in the slide grooves 5 makes the placement rack 102 slide up and down more smoothly, which is convenient for the subsequent oscillation and mixing of the liquid storage bottle to prevent the food sample from settling.

[0035] Example 2

[0036] On the basis of Example 1, a preferred embodiment of the food purine content detection device provided by the present invention is as follows Figures 1 to 5 As shown: the anti-skid component 4 includes an anti-skid suction cup 403, which is fixedly connected to the middle position of the bottom end of the liquid chromatograph body 2, and one side of the bottom end of the liquid chromatograph body 2 is fixedly connected to a fixed box 402, and one side of the fixed box 402 is connected to the inside of the anti-skid suction cup 403 through a conduit, and one side of the inner wall of the fixed box 402 is fixedly connected to a return spring 404, and one end of the return spring 404 is fixedly connected to a piston 405, and one side of the piston 405 is fixedly connected to a pull rod 401 extending to the outside of the fixed box 402. By pressing the pull rod 401, the piston 405 is driven to slide inside the fixed box 402 to compress the return spring 404. After that, the liquid chromatograph body 2 is placed and the bottom end of the anti-skid suction cup 403 is close to the desktop, the elastic force of the return spring 404 can be used to make the piston 405 slide a distance, and then the anti-skid suction cup 403 can be sucked through the fixed box 402, thereby improving the stability of the placement of the liquid chromatograph body 2.

[0037] In this embodiment, a sliding structure is formed between the piston 405 and the interior of the fixed box 402, and a welded integrated structure is formed between one side of the piston 405 and one end of the pull rod 401. The sliding of the piston 405 inside the fixed box 402 facilitates changing the air inside the fixed box 402, thereby changing the negative pressure suction force of the anti-slip suction cup 403.

[0038] The working principle and use process of the utility model are as follows: first, before placing the liquid chromatograph body 2 on a smooth and horizontal table, the pull rod 401 is pressed to drive the piston 405 to slide inside the fixed box 402 to compress the return spring 404, and then the liquid chromatograph body 2 is placed and the bottom end of the anti-skid suction cup 403 is close to the table, and then the pull rod 401 is loosened, and the elastic force of the return spring 404 is used to make the piston 405 slide a certain distance, so that negative pressure is generated inside the fixed box 402, and then the anti-skid suction cup 403 generates suction, thereby improving the stability of the placement of the liquid chromatograph body 2. At the same time, the anti-skid support feet 3 can be used to further increase the friction between the bottom end of the liquid chromatograph body 2 and the table, so as to ensure the firm stability of the placement of the liquid chromatograph body 2 and avoid the liquid chromatograph body 2 from accidentally being subjected to external force and slipping during detection. When the liquid chromatograph body 2 needs to be moved, the pull rod 401 is pushed to release the suction inside the anti-skid suction cup 403, so as to avoid the inconvenience of lifting and carrying the liquid chromatograph body 2 due to excessive suction;

[0039] Then, different numbers of clamping plates 104 are selected to be inserted according to different numbers of liquid storage bottles. At this time, the reserved block 110 is clamped into the placement groove 106 and pushed into the reserved groove 105 to slide to a suitable position, and then different numbers of liquid storage bottles of different specifications are placed in the placement rack 102. At this time, the anti-slip groove 101 is used to improve the friction stability between the bottom end of the liquid storage bottle and the bottom wall of the placement rack 102. Then, the clamping plate 104 is pushed to drive the reserved block 110 to slide in the reserved groove 105, so that the rubber pad 103 is tightly fixed to the inner wall of the placement rack 102 or between the rubber pads 103 and the rubber pads 103, and then the locking bolt is turned. 107 descends so that the bottom end of its nut is close to the top of the placement rack 102, and the reserved block 110 is fixed after sliding, so that different numbers and specifications of liquid storage bottles can be quickly and firmly clamped and fixed. Then, in the subsequent detection process, the vibration motor 109 can be started from time to time to drive the placement rack 102 to slide up and down to compress or stretch the fixed spring 108, and the sliding block 7 is used to slide inside the slide groove 5, so that the placement rack 102 can slide up and down more smoothly, thereby achieving oscillation and mixing of the clamped and fixed liquid storage bottles, avoiding precipitation of food samples and affecting the accuracy of subsequent purine content detection, and then the detection operation can be carried out through the liquid chromatograph body 2.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
