Description

Technical Field

[0001] The utility model belongs to the field of food detection, in particular to a detector for detecting heavy metals in food. Background Art

[0002] Heavy metals are a type of toxic substances, and long-term intake may cause harm to human health. Therefore, during food production and processing, detectors are needed to monitor and detect the heavy metal content in food. It has important application value in the fields of food production, processing, and trade, and can help production companies and regulatory authorities to promptly discover and control heavy metal pollution problems in food, and ensure food safety, which is very important.

[0003] In a Chinese patent with announcement number CN217305107U, a food heavy metal detector is mentioned, including a detector body, a display screen fixed inside the detector body, an upper cover on the top of the detector body, a detection chamber inside the detector body, six slots on the inner wall of the detection chamber, and twelve slide grooves symmetrically distributed with each slot as the center. This solves the problem that when a test tube containing a reagent sample is placed in the groove, the test tube will sink into the groove, making it inconvenient for the staff to grasp the test tube body when taking out the test tube, and grasping the test tube mouth is prone to contamination.

[0004] However, the above patent requires the staff to manually open the cover, which is time-consuming and laborious. The cover may be accidentally opened before the test is completed, causing the sample to be disturbed or contaminated, affecting the test effect. In addition, there is no protective structure, and the control screen is directly exposed to the outside. It may be damaged by collision or accidentally touched during the test, which is inconvenient for personnel to use. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can automatically open and close the cover through the driving mechanism, and limit the current position of the cover after the driving mechanism stops, without the need for staff to manually open and close the cover, which saves time and effort and can effectively avoid the situation in which the sample is disturbed or contaminated by external light due to the opening of the cover during food testing, thereby affecting the accuracy of the test results.

[0014] 2. The utility model can limit the driving range of the driving mechanism through the control mechanism to avoid the situation where the motor continues to start after the cover is completely closed or completely opened, causing jamming and damage.

[0015] 3. The utility model can shield and protect the display screen of the control seat through the protective mechanism when the detector body is performing food testing, so as to prevent it from being directly exposed to the outside and causing collision damage or accidental touch affecting the testing work. The reset mechanism can temporarily limit the position of the protective plate after the protective plate and the display screen are offset, and then release the limited state of the protective plate after the operation is completed. At this time, the protective plate will be automatically moved back to its original position for convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] As attached Figure 1 To Attachment Figure 5 As shown:

[0029] Embodiment 1: The utility model provides a detector for detecting heavy metals in food, including a main body 1, including a detector body 101, a cover plate 102 arranged on one side of the top of the detector body 101, and a control seat 103 arranged on the other side of the top of the detector body 101; a driving mechanism 2, arranged between the detector body 101 and the cover plate 102; a control mechanism 3, arranged on the driving mechanism 2; a protective mechanism 4, arranged on the top of the control seat 103; and a reset mechanism 5, arranged in the protective mechanism 4.

[0030] Specifically, the driving mechanism 2 includes a shell 201 arranged on one side of the detector body 101, a motor 203 arranged at one end of the shell 201, a screw rod 202 arranged at the output end of the motor 203, a fixing frame 205 threadedly arranged on the screw rod 202, a fixing seat 204 arranged on the top of the cover 102, and a guide groove 206 arranged on one side of the fixing seat 204.

[0031] Furthermore, the guide groove 206 is adapted to the movement trajectory of the fixing frame 205 .

[0032] Furthermore, the control mechanism 3 includes a fixing rod 303 arranged on the fixing frame 205 , and fixing blocks 301 are installed on the top of the shell 201 at both ends of the fixing rod 303 , and a control button 302 is arranged on the fixing block 301 .

[0033] As can be seen from the above, when the motor 203 is started during operation, the motor 203 will drive the screw rod 202 to rotate, so as to drive the screw rod 202 to move forward and backward through the threaded connection relationship between the screw rod 202 and the fixing frame 205. When the fixing frame 205 moves, it will move in the guide groove 206. Because the guide groove 206 is inclined, the fixing frame 205 will rotate and open the cover plate 102 through the fixing seat 204 during the movement toward the other end of the device, so as to facilitate personnel to place food samples to be tested or remove food samples that have been tested. There is no need for personnel to manually open or close the cover plate 102, which saves time and effort, and can effectively avoid the situation in which the sample is disturbed or contaminated by external light due to the opening of the cover plate 102 during the food testing process, thereby affecting the accuracy of the test result. It is convenient for personnel to use. The two fixing blocks 301 will limit the range of movement of the fixing frame 205. When the fixing frame 205 touches the control button 302, the motor 203 will be automatically turned off to avoid the situation in which the motor 203 continues to start after the cover plate 102 is completely closed or fully opened, resulting in jamming and damage.

[0034] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the protection mechanism 4 includes guide rails 401 arranged on both sides of the control seat 103, sliders 403 slidably arranged in the guide rails 401, and protection plates 402 arranged between the sliders 403.

[0035] Specifically, the reset mechanism 5 includes a guide rod 404 arranged in the guide rail 401, the guide rod 404 passes through the slider 403, a spring 406 is installed between the guide rail 401 and the slider 403 outside the guide rod 404, a plurality of rubber rings 405 are arranged outside the guide rod 404, a plurality of grooves 407 are arranged on the inner surface of the slider 403 outside the guide rod 404, and the rubber rings 405 are adapted to the grooves 407.

[0036] As can be seen from the above, the protective plate 402 can shield and protect the display screen of the control seat 103 when the device is performing detection work, so as to prevent the display screen from being directly exposed to the outside and causing collision damage or accidental touch affecting the detection work. When it is necessary to control the detector body 101, it is only necessary to pull down the protective plate 402 to expose the display screen, so that it is convenient for personnel to operate and control through the display screen. When the protective plate 402 slides, the slider 403 will slide synchronously on the guide rod 404 to limit the moving direction and range of the protective plate 402. The spring 40 6 synchronously contracts until the multiple rubber rings 405 completely overlap with the multiple card slots 407, so as to limit the current position of the slider 403 together with the protective plate 402. There is no need for the staff to always limit the position of the protective plate 402, which is convenient for the staff to use. When the staff finishes the operation and control, they only need to push the protective plate 402 upward. When the rubber ring 405 is separated from the card slot 407, the spring 406 will push the slider 403 to the initial direction due to the disappearance of resistance, until the protective plate 402 moves to the initial position to cover the display screen of the control seat 103.
