It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0024] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a food heavy metal detector, including a protective shell 1, a detector body 2 is arranged on the surface of the protective shell 1, a lifting protection assembly 3 is arranged on the inner bottom of the protective shell 1, and the lifting protection assembly 3 includes a bidirectional screw 301 and a moving block 302, two groups of moving blocks 302 are symmetrically arranged on the surface of the bidirectional screw 301, and threaded holes 303 are opened inside the moving blocks 302. The tops of the two groups of moving blocks 302 are connected to a group of first rotating shafts 304, the surface of the first rotating shaft 304 is connected to a connecting rod 305, and one side of the connecting rod 305 is connected to a second rotating shaft 306, and the tops of the two groups of second rotating shafts 306 are fixedly connected to a group of trays 307, and the trays The outer surfaces of both sides of 307 are connected with sliders 309, the inner walls of both sides of the protective shell 1 are provided with slide grooves 310, a handle 308 is set at one end of the bidirectional screw 301, the moving block 302 is threadedly connected with the bidirectional screw 301 through the threaded hole 303, the moving block 302 is rotatably connected with the connecting rod 305 through the first rotating shaft 304, the connecting rod 305 is rotatably connected with the tray 307 through the second rotating shaft 306, the handle 308 is fixedly connected to one end of the bidirectional screw 301, the tray 307 is slidably connected with the slide groove 310 through the slider 309, and the outer surface of the slider 309 is in contact with the inner surface wall of the slide groove 310.
[0025] The effect achieved by the entire embodiment 1 is that when the detector body 2 in the protective shell 1 needs to be taken out for use in testing food, the handle 308 can be rotated forwardly first, so that the handle 308 can drive the bidirectional screw 301 to rotate forwardly, thereby allowing the moving blocks 302 on both sides to move inwardly through the threaded holes 303 at the same time. When the two groups of moving blocks 302 move inwardly, the connecting rod 305 will be lifted up through the first rotating shaft 304, and the connecting rod 305 can lift up the tray 307 through the second rotating shaft 306 and move it upward. When the tray 307 moves upward, it will also drive the slider 309 to slide in the slide groove 310, thereby improving the stability of the tray 307 when it moves up and down. When the tray 307 brings the detector body 2 out of the protective shell 1, the handle 308 can be stopped from being rotated, and then the detector body 2 can be taken out of the protective shell 1. The instrument body 2 is taken out for use, and then the food safety test is carried out. After the use of the detector body 2, the detector body 2 can be placed on the surface of the tray 307, and then the handle 308 is rotated in the opposite direction to drive the bidirectional screw 301 to rotate in the opposite direction, so that the two groups of moving blocks 302 can move to both sides at the same time, so that the bottom of the two groups of first rotating shafts 304 also move to both sides, and the two groups of connecting rods 305 drive the two groups of second rotating shafts 306 to move downward. When the two groups of second rotating shafts 306 move downward, they will also drive the detector body 2 on the surface of the tray 307 to shrink into the protective shell 1, so that the storage of the detector body 2 is completed, the convenience of taking out the detector body 2 for use is improved, and the problem that the existing device is more inconvenient when taking out the detector body 2 is avoided, thereby improving the efficiency of food safety detection.
[0026] Embodiment 2, as Figure 1 , Figure 2 and Figure 5 As shown, the four corners of the bottom of the protective shell 1 are connected with shock absorbing components 4, and the shock absorbing component 4 includes a fixed block 401 and a damping spring 402. The damping spring 402 is arranged inside the fixed block 401, and the bottom of the damping spring 402 is connected with a top block 403, and the bottom of the top block 403 is connected with a connecting block 404. The bottom of the connecting block 404 is fixedly connected with an anti-slip pad 405, and the top block 403 forms an elastic structure through the fixed block 401 and the damping spring 402.
[0027] The effect achieved by the entire embodiment 2 is that when the protective shell 1 is placed on the desktop, the anti-slip pad 405 will contact the desktop for the first time. At this time, the anti-slip pad 405 will push the connecting block 404 to drive the top block 403 to squeeze the damping spring 402 and get buffered, which effectively reduces the impact force when the protective shell 1 contacts the desktop, plays a protective role for the detector body 2, and the anti-slip pad 405 can play an anti-slip role to prevent the protective shell 1 from sliding on the desktop and causing the detector body 2 to be damaged.
[0028] Working principle: When the detector body 2 needs to be taken out for use, the handle 308 can be turned to drive the bidirectional screw 301 to rotate, so that the two sets of moving blocks 302 move inward at the same time, and push the tray 307 to move upward, so that the detector body 2 can be taken out from the protective shell 1, avoiding the inconvenience of the existing device when taking out the detector body 2, and improving the efficiency of food safety detection. When the protective shell 1 is placed on the desktop, the top block 403 will squeeze the damping spring 402 and be buffered, thereby reducing the impact force when the protective shell 1 contacts the desktop, thereby protecting the detector body 2.
