[0026] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined or described in one drawing, it will not be necessary to further discuss and describe it specifically in the description of the subsequent drawings.

[0027] As Figures 1-4 shown, the present invention provides a technical solution: a food detection sampling device for food safety, including a base 1 and universal wheels 101 installed at the bottom end of the base 1. The base 1 is a U-shaped structure; a lifting structure 2, arranged at the top end of the base 1, for adjusting the height of the sampling structure 4; a moving structure 3, arranged at the top end of the lifting structure 2, for horizontally moving the sampling structure 4 longitudinally along the base 1; a sampling structure 4, arranged at the bottom end of the moving structure 3, for sampling during food detection.

[0028] As Figures 1 to 4 shown, in order to adjust the height of the sampling structure 4 and facilitate sampling of foods at different placement depths, a lifting structure 2 is provided on the top end of the base 1. Specifically, the lifting structure 2 includes a support frame 201. The support frame 201 is a U-shaped structure and is connected to the top end of the base 1. Sliding grooves 202 are formed on both inner walls of the support frame 201. A threaded rod 203 and a guide rod 205 are provided between the inner side of the top of the support frame 201 and the top end of the base 1. The guide rod 205 is located on both sides of the threaded rod 203, and a sliding block 204 is slidably arranged on the outer wall of the guide rod 205. The sliding block 204 is adapted to the sliding groove 202. A threaded sleeve 208 is threadedly connected to the outer wall of the threaded rod 203, and a motor 207 is installed at the top end of the support frame 201. The output end of the motor 207 is connected to the top end of the threaded rod 203. Both ends of the threaded sleeve 208 are connected to the sliding block 204, and a connecting plate 206 formed integrally is provided between the threaded sleeve 208 and the sliding block 204. It should be clearly understood that in the embodiment of the present application, the motor 207 serves as the power source of the lifting structure 2. The motor 207 is connected to an external power supply. As can be seen from the foregoing, the motor 207 can drive the rotation of the threaded rod 203. The threaded rod 203 is connected to the base 1 through a plain bearing. When the threaded rod 203 rotates, it can drive the threaded sleeve 208 to rise and fall. In order to prevent the threaded sleeve 208 from idling, the sliding block 204 is connected to both ends of the threaded sleeve 208. A through hole is formed in the center of the sliding block 204. In order to enable movement on the outer wall of the guide rod 205, the sliding block 204 can also move freely on the sliding groove 202. At the same time, a connecting plate 206 is provided between the sliding block 204 and the threaded sleeve 208. The connecting plate 206 is in a T-shaped structure.

[0029] As Figures 1 to 4As shown in the figure, in order to be able to move the sampling structure 4 along the longitudinal position of the base 1, a moving structure 3 is provided at the bottom end of the connecting plate 206. Specifically, the moving structure 3 includes a fixing plate 301 and a moving groove 302. The moving groove 302 is opened at the bottom end of the connecting plate 206. The fixing plate 301 is connected to both ends of the connecting plate 206. A lead screw 304 is rotatably arranged between the fixing plates 301. A lead screw seat 306 is threadedly connected to the outer wall of the lead screw 304. Connecting rods 305 are installed at both ends of the lead screw seat 306. The connecting rods 305 are of an L-shaped structure. The other end of the connecting rod 305 is installed with a moving block 303. The moving block 303 is adapted to the moving groove 302. A connecting frame 307 is installed at the bottom end of the lead screw seat 306. The connecting frame 307 is of a square frame structure with a hole in the middle. It should be clearly understood that in the embodiment of the present application, the power source of the moving structure 3 is also the motor 207. Since the motor 207 is a prior art, it is not shown in the present application. When the motor 207 drives the lead screw 304 to rotate, the lead screw seat 306 threadedly connected to the outer wall of the lead screw 304 can move along with the rotation of the lead screw 304. At the same time, the moving block 303 is connected to both ends of the lead screw seat 306 through the connecting rods 305, so that the moving block 303 can move freely on the inner wall of the moving groove 302. At the same time, in order to be able to install the sampling structure 4, a connecting frame 307 is connected to the bottom end of the moving block 303. The connecting frame 307 can facilitate the installation and disassembly of the sampling structure 4.

[0030] As Figures 1 to 4 shown, in the present application, the sampling structure 4 can sample the food in different containers containing food. Specifically, the sampling structure 4 includes a sampling tube 401. Connecting pieces 402 are equidistantly distributed on the outer wall of the sampling tube 401. The top ends of the connecting pieces 402 and the bottom end of the connecting frame 307 are provided with coaxial connecting holes. A fixing rod 403 is arranged in the connecting hole. A rubber plug 405 is movably arranged on the inner wall of the sampling tube 401. A support rod 407 is installed at the top end of the rubber plug 405. An electric telescopic rod 408 is installed at the top end of the support rod 407. The electric telescopic rod 408 is connected to the connecting frame 307. And a sampling pipe 404 is integrally formed at the bottom end of the sampling tube 401. An out-sample pipe 406 is installed on the outer wall of the sampling tube 401. It should be clearly understood that in the embodiment of the present application, the sampling tube 401 can be adjusted in height and moved in position along with the lifting structure 2 and the moving structure 3. At the same time, it can also avoid sampling the food manually, reducing the risk of food contamination. The electric telescopic rod 408 can drive the support rod 407 to move upward. The moving support rod 407 can drive the rubber plug 405 to move. When the rubber plug 405 moves upward, it can extract the food through the sampling pipe 404. The extracted food is discharged from the out-sample pipe 406 into a beaker or other tools for detecting food, which can reduce the direct contact with the food and avoid the problem of food infection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
