Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and more specifically to a portable rapid food microbial testing instrument. Background Technology

[0002] In recent years, molecular-level detection of pathogenic bacteria in food has become rapidly widespread. The detection process mainly includes three steps: pretreatment, nucleic acid extraction, and nucleic acid amplification and detection. In the pretreatment process, the sample is mechanically pulverized and then cultured in an incubator.

[0003] A search revealed a portable rapid food microbial detector disclosed in publication number CN211426438U, comprising a detector body, the detector body including a housing, an installation frame installed inside the housing, a fixed base inside the installation frame, a support rod on the fixed base, a cover plate welded to one end of the support rod, an installation hole on the fixed base, a locking hole on one side of the installation hole, a switch on one side of the housing, a support tube inside the installation frame that cooperates with the fixed base, an installation base at the bottom of the installation frame, a motor installed on the installation base, an output shaft on the motor, a working part installed on the output shaft, a heating strip inside the installation frame that cooperates with the support tube, and a shock-absorbing spring on one side of the installation frame, the installation frame being fixed inside the housing by the shock-absorbing spring.

[0004] The above-mentioned technical solutions have certain beneficial effects, but in actual use, when the eccentric wheel rotates, the kinetic energy generated by the eccentric wheel cannot drive the mounting frame and the test sample to compress the spring, thus failing to generate vibration. Therefore, we propose a portable rapid food microbial detection instrument. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a portable food microbial rapid detection instrument to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a portable food microbial rapid detection instrument, including a mounting box, with connecting handles symmetrically arranged on the outer surface of the mounting box, a fixing through groove opened at the top of the mounting box, a fixing cavity opened inside the mounting box, a connecting buffer mechanism fixedly connected to one end of the inner side of the mounting box, a connecting reset mechanism fixedly connected to the other end of the inner side of the mounting box, a servo motor fixedly connected to the top of the mounting box near the connecting buffer mechanism, a connecting cam fixedly connected to the output end of the servo motor, a sample box movably placed inside the mounting box, a plurality of fixing placement grooves opened inside the sample box, and sample test tubes placed inside the fixing placement grooves;

[0007] Furthermore, the top of the mounting box is provided with a movable limiting mechanism, and the top of the mounting box is symmetrically provided with a fixed limiting mechanism.

[0009] Furthermore, the connection reset mechanism includes a compression reset spring, and the other end of the compression reset spring is fixedly connected to a pressure-bearing push plate.

[0010] Furthermore, the side of the buffer plate away from the buffer spring and the side of the connecting pressure push plate away from the compression reset spring are respectively attached to the outer side of the sample box.

[0011] Furthermore, the movable limiting mechanism includes a movable limiting top plate, and fixed connecting arms are symmetrically provided at the top of the movable limiting top plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a servo motor to drive a connecting cam, which pushes the sample box laterally. This causes the sample box to push the connecting reset mechanism. When the connecting cam stops pushing the sample box, the connecting reset mechanism pushes the sample box back to its original position. The connecting buffer mechanism also buffers the movement of the sample box, preventing impact on the connecting cam and the output of the servo motor. It also stably vibrates the sample box, thus mixing the samples. The operation is convenient.

[0015] 2. This utility model, through the provision of a movable limiting mechanism and a fixed limiting mechanism, allows the fixed limiting mechanism to limit the movable limiting mechanism when the sample box is inside the mounting box, thus restricting the sample box and enabling it to move stably inside the mounting box. This improves overall stability and facilitates operation. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1-5 This utility model provides a portable food microbial rapid detection instrument, including a mounting box 1. The mounting box 1 has symmetrical connecting handles 2 on its outer surface. The top of the mounting box 1 has a fixing through groove 3. The inside of the mounting box 1 has a fixing cavity 4. One end of the inner side of the mounting box 1 is fixedly connected to a connecting buffer mechanism 5. The other end of the inner side of the mounting box 1 is fixedly connected to a connecting reset mechanism 6. A servo motor 7 is fixedly connected to the top of the mounting box 1 near the connecting buffer mechanism 5. The output end of the servo motor 7 is fixedly connected to a connecting cam 8. A sample box 9 is movably placed inside the mounting box 1. The sample box 9 has several fixing placement grooves 10 inside. Sample test tubes 11 are placed inside the fixing placement grooves 10.

[0024] The top of the mounting box 1 is provided with a movable limiting mechanism 12, and the top of the mounting box 1 is symmetrically provided with a fixed limiting mechanism 13.

[0025] The connecting buffer mechanism 5 includes a fixed guide block 14, with fixed guide grooves 15 symmetrically arranged inside the fixed guide block 14. A buffer spring 17 is provided on the inner side of the fixed guide groove 15, and a buffer plate 18 is fixedly connected to the other end of the buffer spring 17. An arc-shaped groove 16 is provided in the middle of one side of the fixed guide block 14, so that when the sample box 9 moves laterally, it can push the buffer plate 18 and compress the buffer spring 17 to buffer the sample box 9, thereby avoiding impact on the output end of the connecting cam 8 and the servo motor 7 when the sample box 9 moves laterally. The operation is convenient.

[0026] The connection reset mechanism 6 includes a compression reset spring 19, the other end of which is fixedly connected to a connection pressure push plate 20. When the sample box 9 moves laterally, the connection pressure push plate 20 can be pushed to compress the compression reset spring 19. Conversely, when the compression reset spring 19 rebounds, it can push the connection pressure push plate 20 to push the sample box 9, so that the sample box 9 can move stably and is easy to operate.

[0027] The side of the buffer plate 18 away from the buffer spring 17 and the side of the connecting pressure push plate 20 away from the compression reset spring 19 are respectively attached to the outer side of the sample box 9, so that the sample box 9 can be stably placed between the buffer plate 18 and the connecting pressure push plate 20.

[0028] The movable limiting mechanism 12 includes a movable limiting top plate 21. The top of the movable limiting top plate 21 is symmetrically provided with fixed connecting arms 23. Both ends of the fixed connecting arms 23 are provided with limiting grooves 24. A lifting handle 22 is fixedly connected to the middle of the top of the movable limiting top plate 21, which facilitates the movement of the lifting handle 22, thereby moving the movable limiting top plate 21 and the fixed connecting arms 23. This allows the movable limiting top plate 21 to be placed inside the fixed through groove 3 and on top of the sample box 9. The limiting grooves 24 at the ends of the fixed connecting arms 23 are connected and cooperated with the fixed limiting mechanism 13, thereby limiting the fixed connecting arms 23 and the movable limiting top plate 21. The operation is convenient.

[0029] The fixed limiting mechanism 13 includes a fixed sleeve 25. A connecting spring 26 is fixedly connected to the inner side of the fixed sleeve 25. A connecting mounting plate 27 is fixedly connected to one end of the connecting spring 26. A fixed connecting cylinder 28 is fixedly connected to the side of the connecting mounting plate 27 away from the connecting spring 26. A connecting hemisphere 29 is fixedly connected to the end of the fixed connecting cylinder 28 away from the connecting mounting plate 27. The outer surface of the connecting hemisphere 29 is in contact with the inner side of the limiting groove 24, so that when the end of the fixed connecting arm 23 moves downward, it can squeeze the connecting hemisphere 29, so that the connecting hemisphere 29 can drive the fixed connecting cylinder 28 and the connecting mounting plate 27 to move, and squeeze the connecting spring 26, thereby adjusting itself. When the bottom of the fixed connecting arm 23 is in contact with the top of the mounting box 1, the connecting spring 26 can reset the connecting mounting plate 27, the fixed connecting cylinder 28 and the connecting hemisphere 29, so that the connecting hemisphere 29 can be inserted into the inner side of the limiting groove 24, thereby limiting the connection.

[0030] The working principle of this utility model is as follows: During use, the sample tube 11 is placed inside the fixed placement groove 10, and then the sample box 9 and the fixed placement groove 10 are placed inside the mounting box 1. Next, the lifting handle 22 is moved, causing the movable limiting top plate 21 and the fixed connecting arm 23 to move, so that the movable limiting top plate 21 can be placed inside the fixed through groove 3 and at the top of the sample box 9. Simultaneously, when the end of the fixed connecting arm 23 moves downwards, it can compress the connecting hemisphere 29, causing the connecting hemisphere 29 to move the fixed connecting cylinder 28 and the connecting mounting plate 27, compressing the connecting spring 26, thus self-adjusting. When the bottom of the fixed connecting arm 23 is in contact with the top of the mounting box 1, the connecting spring 26 can reset the connecting mounting plate 27, the fixed connecting cylinder 28, and the connecting hemisphere 29, allowing the connecting hemisphere 29 to... The sample box 9 is inserted into the inner side of the limiting groove 24 to achieve connection limiting. Then, the servo motor 7 drives the connecting cam 8, which cyclically pushes the sample box 9 towards the connecting pressure push plate 20. This pushes the connecting pressure push plate 20 and compresses the compression return spring 19. When the connecting cam 8 stops pushing the sample box 9 during its cyclic rotation, the compression return spring 19 pushes the connecting pressure push plate 20, causing the sample box 9 and the fixed placement groove 10 to move inside the mounting box 1. This allows the sample box 9 to impact the buffer plate 18, buffering the buffer spring 17. The sample box 9 and the sample tube 11 can move stably at the bottom of the movable limiting top plate 21, stably vibrating the sample tube 11 to process the sample. The overall structure is simple and the operation is convenient and quick.
