Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically relating to a food sampling and testing workbench. Background Technology

[0002] Food testing is a crucial step in ensuring food safety and protecting public health. Through scientific and systematic testing methods, the composition, quality, and safety of food are comprehensively evaluated. Generally, a sterile workbench is required when sampling and testing food. During food testing, staff typically place the food inside a beaker and then conduct the test. However, the beaker needs to be secured during use to prevent accidental tipping and interruption of the testing process. Although some existing sterile workbench have structures for clamping and securing beakers, they often have certain shortcomings in practical use and therefore need to be improved.

[0003] Chinese patent CN219816329U discloses a sterile workbench for food sampling and testing, relating to the field of food testing technology. This sterile workbench includes a sterile workbench with a connecting plate fixedly connected to its top. Two identical sliding grooves are formed on the left side of the connecting plate, each containing a clamping mechanism. The clamping mechanism includes a round rod, which is fixedly connected to another round rod within the groove. A slider is movably sleeved on the surface of the round rod, and a first spring is movably sleeved on the surface of the round rod. By rotating the threaded rod to the left, the long plate ultimately pushes the limiting block into the limiting groove, thereby fixing the clamping plate after clamping the beaker. This effectively improves the clamping stability of the beaker, thus enhancing the stability of the beaker placed on the sterile workbench and further improving the effectiveness of the sterile workbench in food testing.

[0004] However, while the above-mentioned technical solution can achieve the purpose of clamping and fixing beakers, it has certain limitations in practical use, especially when clamping beakers of different sizes. If the limiting groove is located between two limiting blocks after the beaker is clamped, the limiting blocks are difficult to align with the limiting groove, making it difficult to keep the slider fixed. Consequently, the beaker is difficult to clamp, which may cause the aseptic workbench to tip over due to external factors, thus affecting the smooth progress of food testing. Utility Model Content

[0005] The purpose of this invention is to provide a food sampling and testing workbench to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A food sampling and testing workbench includes: a sterile workbench body, a transparent frame fixedly connected inside the sterile workbench body, a testing cavity opened inside the transparent frame, a clamping seat fixedly connected to the middle of the bottom wall of the testing cavity, a hydraulic telescopic rod fixedly and penetrating through the bottom end of the back of the transparent frame, a first toothed plate fixedly connected to the output end of the hydraulic telescopic rod, two first gears meshing on the surface of the first toothed plate, a second gear fixedly connected to the bottom of the first gear, a rotating shaft fixedly connected inside the second gear, and the surface of the rotating shaft fixedly and penetrating through the interior of the first gear and the second gear, the bottom end of the rotating shaft rotatably disposed inside the clamping seat, two second toothed plates meshing on the surface of the second gear, and a clamping plate fixedly connected to one side of the second toothed plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1 to 3 As shown, a food sampling and testing workbench includes a sterile workbench body 1. A transparent frame 2 is fixedly connected inside the sterile workbench body 1. A testing cavity 3 is opened inside the transparent frame 2. A clamping seat 4 is fixedly connected to the middle of the bottom wall of the testing cavity 3. A hydraulic telescopic rod 5 is fixedly and penetrates the bottom end of the back of the transparent frame 2. A first toothed plate 6 is fixedly connected to the output end of the hydraulic telescopic rod 5. Two first gears 7 are meshed on the surface of the first toothed plate 6. A second gear 8 is fixedly connected to the bottom of the first gear 7. A rotating shaft is fixedly connected inside the second gear 8. The surface of the rotating shaft is fixed and penetrates the interior of the first gear 7 and the second gear 8. The bottom end of the rotating shaft is rotatably disposed inside the clamping seat 4. Two second toothed plates 9 are meshed on the surface of the second gear 8. A clamping plate 10 is fixedly connected to one side of the second toothed plate 9.

[0024] The transparent frame 2 allows staff to observe the interior of the sterile workbench body 1 from the outside. The detection chamber 3 allows beakers to be placed inside. The clamping seat 4 stabilizes the beaker and clamps it. The hydraulic telescopic rod 5 moves the first toothed plate 6 left and right, causing the first toothed plate 6 to rotate the two first gears 7. The rotation of the first gears 7 causes the second gears 8 to rotate, which in turn causes the two second gears 8 to move the second toothed plate 9. Finally, the clamping plates 10 move towards or away from each other, achieving the purpose of clamping the beaker.

[0025] The clamping base 4 has a guide rod 11 fixed inside and passing through it, and the clamping plate 10 slides through the surface of the guide rod 11. The guide rod 11 is provided to guide the two clamping plates 10 when they move towards or away from each other.

[0026] The transparent frame 2 has a working groove inside, and a partition 15 is slidably connected inside the working groove. The working groove allows the partition 15 to slide inside, making it easy for workers to open the transparent frame 2.

[0027] A control panel is fixedly connected to the top of one side of the sterile workbench body 1, and the control panel is electrically connected to the hydraulic telescopic rod 5.

[0028] Example 2:

[0029] Please see Figure 1 , Figure 2 and Figure 4 As shown, the clamping plate 10 has a strip-shaped groove inside, and a first Velcro 12 is fixedly connected to the inner side wall of the strip-shaped groove. The strip-shaped groove allows the first Velcro 12 to be fixed to its inner side wall.

[0030] The surface of the first hook and loop fastener 12 is connected to a second hook and loop fastener 13, and the back of the second hook and loop fastener 13 is fixedly connected to an anti-slip pad 14. The second hook and loop fastener 13 is easy to connect with the first hook and loop fastener 12, thereby fixing the anti-slip pad 14 inside the groove. The anti-slip pad 14 makes the clamping plate 10 more stable when clamping the beaker, and at the same time provides a certain degree of protection for the surface of the beaker. After long-term use and wear, the anti-slip pad 14 can be easily removed and replaced with a new one.

[0031] The working principle of this utility model is as follows: The operator places the food to be tested inside the beaker beforehand, and then places the beaker into the clamping seat 4 inside the testing chamber 3. The operator then controls the hydraulic telescopic rod 5 to start, and the output end of the hydraulic telescopic rod 5 drives the first toothed plate 6 to move to the right, which in turn causes the two first gears 7 to rotate. The two first gears 7 then drive the second gear 8 to rotate, which in turn causes the second gear 8 to drive the second toothed plate 9 to move to opposite positions, thereby causing the two clamping plates 10 to move to opposite positions, thus making the beaker clamped stably. At this time, the surface of the anti-slip pad 14 contacts the surface of the beaker, making it clamped stably. The operator then pulls the partition 15 down to isolate the testing chamber 3 from the outside. Then, the food inside the beaker can be tested through the sterile workbench body 1. When the anti-slip pad 14 is worn after long-term use, the operator can directly peel off the first hook and loop fastener 12 through the anti-slip pad 14 to separate it from the second hook and loop fastener 13. Then, a new anti-slip pad 14 can be replaced and glued to the first hook and loop fastener 12.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
