Description

Technical Field

[0001] The utility model belongs to the technical field of food detection, and in particular relates to a sampling device for food safety detection of pre-prepared dishes. Background Art

[0002] Pre-prepared dishes are pre-packaged dishes made from edible agricultural products and other ingredients. They are industrially pre-processed and can only be eaten after being heated or cooked. Compared with freshly cooked dishes, pre-prepared dishes sold to various places require higher food safety. Therefore, safety testing of pre-prepared dishes is extremely important. For safety testing of pre-prepared soup dishes, the sediment at the bottom is more valuable for testing than the clear soup at the top. Existing testing devices usually use a straw to suck up samples. Two suction operations are required for the sediment and clear soup, and the sample is easily muddied. Therefore, the user is required to have certain work skills in use, which in turn causes certain limitations in use. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 4 The sampling device for food safety detection of pre-prepared dishes shown in the figure includes a suction tube 8, a first push column 28 is inserted into the interior of the suction tube 8 and slidably connected, the end of the first push column 28 is fixedly connected to a sealing disk 27, and the other end of the first push column 28 is fixedly connected to a second push column 29. There are two suction tubes 8, and the tops of the two first push columns 28 are fixedly connected to a common pull plate 3. The end of the suction tube 8 is inserted and slidably connected to an insertion tube 22, and the outer wall of the insertion tube 22 is provided with evenly distributed liquid holes 23. The end of the insertion tube 22 is fixedly connected to a flexible suction tube 11, and the length of one flexible suction tube 11 is longer than the other flexible suction tube 11. The outer wall of the suction tube 8 is fixedly connected to two upper and lower fixed plates 9. The two fixed plates 9 are fixedly connected with evenly distributed connecting columns 10, the outer wall of the fixed plate 9 is slidably connected with the covering shell 1, and the inner wall of the covering shell 1 is slidably connected with the second push frame 4 on both sides. The top of one of the fixed plates 9 is fixedly connected with the first push frame 2 through the connecting column 10, and the first push frame 2 and the second push frame 4 are self-lockingly matched. By setting the suction tube 8, flexible straws 11 of different lengths and a common pull plate 3, during use, pressing and toggling the pull plate 3 can carry out layered extraction of the sediment layer and the clear soup layer of the sample through the flexible straw 11. Only one operation is required during the process. At the same time, pressing the first push frame 2 can synchronously drive the pull plate 3 to move downward, thereby adjusting the length of the flexible straw 11.

[0022] The flexible straw 11 is provided with a turbine structure 16. The outer wall of the flexible straw 11 is slidably connected to a correction tube 14. The outer walls of the two correction tubes 14 are fixedly connected to a matching plate 18 and an L-shaped plate 17 respectively. The end of the matching plate 18 is fixedly connected to a slide rod 19. The end of the slide rod 19 is fixedly connected to a limit block 20. The end of the L-shaped plate 17 is fixedly connected to a baffle 21, and the slide rod 19 is inserted and slidably connected to the upper and lower sides of the baffle 21. The end of the baffle 21 is fixedly connected to a connecting rod 6, and the connecting rod 6 is inserted and slidably connected to the fixed plate 18. On both sides of the outer wall of the fixed plate 9, the ends of the connecting rod 6 are fixedly connected to two adjusting blocks 7. Through this design, the flexible straw 11 in the turbine structure 16 state can be accommodated in a smaller space to cover the interior of the shell 1. When in use, the adjusting block 7 is pressed to make the connecting rod 6 press the baffle 21 to slide down along the slide rod 19. When the baffle 21 contacts the matching plate 18, it synchronously drives the two correction tubes 14 to move downward, thereby correcting and straightening the flexible straw 11 in the turbine structure 16 state, so that food sampling can be carried out normally.

[0023] A through hole 5 that matches the shape of the adjustment block 7 is provided on the outer wall of the first push frame 2 and the pull plate 3. Through this design, the adjustment block 7 can pass through the first push frame 2 and the pull plate 3, obtaining a larger movable space for the connecting rod 6, thereby increasing the pressing stroke of the connecting rod 6.

[0024] The outer wall of the first push rack 2 is fixedly connected to the second magnetic member 13 on both sides, and the inner wall of the second push rack 4 is fixedly connected to the first magnetic member 12 on both sides, and the first magnetic member 12 and the second magnetic member 13 are magnetically matched. The interior of the suction tube 8 is fixedly connected to the sleeve 26 through the bracket, and the interior of the sleeve 26 is slidably connected to the sealing block 24. A spring 25 is fixedly connected between the sealing block 24 and the inner wall of the sleeve 26, and a connecting plate 15 is fixedly connected between the second push rack 4 and the cannula 22. Through this design, the first push rack 2 and the second push rack 4 can be separated by pressing the second push rack 4 with one hand and sliding the first push rack 2 with the other hand. At this time, since the second push rack 4 is in a fixed state, the cannula 22 can be removed from the interior of the suction tube 8. At this time, after the sealing block 24 loses the supporting force from the cannula 22, the sleeve 26 can rebound and push out the sealing block 24 to seal the opening of the suction tube 8, thereby completing the sealing inside the suction tube 8. Compared with the prior art, it can effectively prevent the sample inside the suction tube 8 from deteriorating.

[0025] An extension hole is provided at the bottom of the covering shell 1, and the extension hole is adapted to the shape of the matching plate 18 and the L-shaped plate 17. Through this design, the flexible straw 11 in the turbine structure 16 state can be stored while the extension of the flexible straw 11 during the correction process can be facilitated.

[0026] Working principle:

[0027] By providing the suction tube 8 and the flexible suction tube 11 and other structures, the sediment layer and the clear soup layer of the prepared soup can be extracted in layers through a single sampling operation, thereby greatly avoiding the damage to the sediment layer and the clear soup layer caused by multiple samplings, thereby ensuring the accuracy of the sample;

[0028] By providing the matching plate 18 and the baffle 21, the flexible straw 11 is placed in the turbine structure 16 when not in use, making it easier to store. When in use, the adjustment block 7 is pressed to push the baffle 21 downward, driving the two correction tubes 14 to move downward together, thereby straightening the two flexible straws 11, thereby enabling correct sampling and testing.

[0029] By providing the sealing block 24 and the cannula 22 and other structures, after the second pusher 4 is fixed, the cannula 22 can be pulled out of the interior of the withdrawal tube 8 by pulling the first pusher 2, and then the sealing block 24 blocks the opening of the withdrawal tube 8 under the push of the spring 25, thereby ensuring the sealing of the withdrawal tube 8 and preventing the sample inside the withdrawal tube 8 from deteriorating.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the principles of the present invention described in the above embodiments and the specification. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
