Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to a sampling device for food safety detection. Background Technique

[0002] After food production, it needs to be specially detected. Among them, food and beverages need to be sampled and detected after production to prevent unqualified quality. Before detection, a sampling cylinder is usually used to sample and store the liquid to be detected.

[0003] After retrieval, the existing Chinese patent publication number is CN219046030U. This utility model provides a sampling device for food safety detection, including a sampling cylinder. A plurality of fixed pipes are hermetically and fixedly connected to the bottom of the sampling cylinder. A sampling pipe is hermetically slidably connected to the inner wall of the fixed pipe. The sampling pipe is used to suck and detect food solutions. A plurality of threaded grooves are opened on the opposite side walls of the sampling pipe. Bolts are threadedly connected to the opposite side walls of the fixed pipe. The side wall of the bolt is threadedly connected to the inner wall of one of the threaded grooves. A sliding plate is hermetically slidably connected to the inner wall of the sampling cylinder. A threaded rod is threadedly connected to the top of the sampling cylinder. The lower end of the threaded rod is rotatably connected to the upper end of the sliding plate. Through the cooperation of the bolt and the threaded groove, the positions of a plurality of sampling pipes can be adjusted at different heights, so that multiple sampling pipes can suck samples of different food materials at different positions respectively, so that detection can be carried out after one-time sampling, avoiding the need for frequent sampling in the prior art, which will delay the detection efficiency and increase the detection cost.

[0004] However, in the above technology, the following disadvantages will occur during use: After the sampling cylinder of the extraction device extracts the liquid to be detected, there is no limit mechanism at the pull rod part of the sampling cylinder, resulting in the situation that the pull rod part is likely to move during the storage of the liquid to be detected, causing the liquid to be detected inside the sampling cylinder to leak out, which is not conducive to the smooth progress of subsequent detection work. Therefore, those skilled in the art provide a sampling device for food safety detection to solve the problems raised in the above background technique. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a sampling device for food safety detection, aiming to improve the situation that after the sampling cylinder of the extraction device extracts the liquid to be detected, there is no limit mechanism at the pull rod part of the sampling cylinder, resulting in the situation that the pull rod part is likely to move during the storage of the liquid to be detected, causing the liquid to be detected inside the sampling cylinder to leak out, which is not conducive to the smooth progress of subsequent detection work.

[0006] To achieve the above object, the utility model adopts the following technical solutions: It includes a first sampling cylinder. On both sides above the first sampling cylinder, there are fixedly connected first fixing rods. Inside the upper parts of the two first fixing rods, there are sliding clamping connections with limiting clips. At one end of each of the two limiting clips, there is fixedly connected a limiting leather pad. On one side of the upper ends of the two limiting clips, there is fixedly connected a sliding rod. On the other two sides above the first sampling cylinder, there are fixedly connected second fixing rods. On one side of the upper ends of the two second fixing rods, there is fixedly connected a limiting rod. Above the first sampling cylinder, there is a turntable. On both sides of the turntable, there are opened first sliding holes. On the other two sides of the turntable, there are opened second sliding holes. The outer surfaces of the two sliding rods are respectively slidably connected to the interiors of the two second sliding holes. The outer surfaces of the two limiting rods are respectively slidably connected to the interiors of the two first sliding holes.

[0007] As a further description of the above technical solution: First, draw the liquid to be detected into the first sampling cylinder. Subsequently, hold the outside of the first sampling cylinder by hand, and turn the turntable counterclockwise with the other hand. The sliding rod on the limiting clip will move from one side inside the second sliding hole to the other side. At the same time, the two limiting clips will also gather inward to perform a limiting clamping function. At the same time, the limiting leather pad provided on the limiting clip can effectively increase the friction force of the contact surface of the limiting clip, making the clamping more stable. On the contrary, when loosening the limit, only need to turn the turntable clockwise to release the limit.

[0008] Preferably, a second sampling cylinder is provided below the first sampling cylinder, and a connecting cylinder is fixedly connected to the upper end of the second sampling cylinder.

[0009] As a further description of the above technical solution: The first sampling cylinder and the second sampling cylinder can be disassembled from each other, making it more convenient to clean the device after use.

[0010] Preferably, the inner surface of the second sampling cylinder is threadedly connected to the lower end of the first sampling cylinder, and a sealing ring is fixedly connected to the lower end of the first sampling cylinder.

[0011] As a further description of the above technical solution: The sealing ring can effectively seal between the first sampling cylinder and the second sampling cylinder, making the first sampling cylinder and the second sampling cylinder have better sealing during use and preventing liquid leakage.

[0012] Preferably, a sealing groove is opened at the upper end of the second sampling cylinder, and the outer surface of the sealing ring is inserted into the interior of the sealing groove.

[0013] As a further description of the above technical solution: The working principles of the sealing groove and the sealing ring are the same, and no more details will be elaborated. Both can effectively improve the sealing performance at the connection between the first sampling cylinder and the second sampling cylinder.

[0014] Preferably, a protective cover is threadedly connected to the lower end of the second sampling cylinder, and a sampling needle is fixedly communicated with the lower end of the second sampling cylinder.

[0015] As a further description of the above technical solution: The protective cover can protect the sampling needle part when the device is not in use, and can avoid the situation that the sampling needle is broken or bent due to external force, which affects sampling.

[0016] Preferably, a suction mechanism is arranged inside the first sampling cylinder, and the outer surface of the suction mechanism is threadedly connected above the first sampling cylinder.

[0017] As a further description of the above technical solution: By rotating the suction device, the liquid to be detected can be sucked into the device for storage.

[0018] Preferably, a handle is fixedly connected to the upper end of the suction mechanism.

[0019] As a further description of the above technical solution: The handle can effectively improve the convenience when using the rotating suction mechanism, making the device more convenient to use.

[0020] Preferably, anti-slip sheets are evenly fixedly connected around the turntable.

[0021] As a further description of the above technical solution: The anti-slip sheets can effectively increase the friction around the turntable, making it more convenient for the hand to rotate.

[0022] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0023] 1. In the present utility model, during use, first draw the liquid to be detected into the first sampling cylinder. Then, hold the outside of the first sampling cylinder by hand, and rotate the turntable counterclockwise with the other hand. The slide rod on the limit clip will move from one side inside the second slide hole to the other side. At the same time, its two limit clips will also move closer to the inside to perform the limit clamping function. At the same time, the limit leather pads provided on the limit clips can effectively increase the friction on the contact surface of the limit clips, making the clamping more stable. On the contrary, when loosening the limit, only rotate the turntable clockwise to release the limit. By this method, after sampling, the upper part of the first sampling cylinder can be limited, so that the device will not leak liquid after sampling, effectively avoiding the problem that the detection work cannot be carried out smoothly due to liquid leakage.

[0024] 2. In the present utility model, when the first sampling cylinder needs to be cleaned after the device is used up, only by rotating the first sampling cylinder and the second sampling cylinder to separate them can the inside of the first sampling cylinder be quickly cleaned. And a sealing ring is fixed at the connection between the first sampling cylinder and the second sampling cylinder. The sealing ring can be inserted into the sealing groove. In fact, when the first sampling cylinder and the second sampling cylinder are in normal use, their sealing performance is better. By this method, the cleaning of the device after use can be made more convenient, avoiding the problem of detection data deviation caused by improper cleaning of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to the attached Figure 1 - attached Figure 3, An embodiment provided by the present utility model: a first sampling cylinder 1, characterized in that: both sides above the first sampling cylinder 1 are fixedly connected with first fixing rods 7, and the interiors of the two first fixing rods 7 above are both slidably clamped with limit clips 10. One end of each of the two limit clips 10 is fixedly connected with a limit leather pad 19. One side of the upper ends of the two limit clips 10 is fixedly connected with a slide rod 13. The other two sides above the first sampling cylinder 1 are fixedly connected with second fixing rods 6. One side of the upper ends of the two second fixing rods 6 is fixedly connected with a limit rod 5. A turntable 4 is arranged above the first sampling cylinder 1. One first slide hole 11 is opened on each of the two sides of the turntable 4, and one second slide hole 12 is opened on each of the other two sides of the turntable 4. The outer surfaces of the two slide rods 13 are respectively slidably connected with the interiors of the two second slide holes 12, and the outer surfaces of the two limit rods 5 are respectively slidably connected with the interiors of the two first slide holes 11.

[0033] In this embodiment, when in use, first draw the liquid to be detected into the first sampling cylinder 1. Subsequently, hold the outside of the first sampling cylinder 1 by hand, and turn the turntable 4 counterclockwise with the other hand. The slide rod 13 on the limit clip 10 will move from one side inside the second slide hole 12 to the other side. At the same time, the two limit clips 10 will also gather inward to perform a limit clamping function. At the same time, the limit leather pad 19 provided on the limit clip 10 can effectively increase the friction force of the contact surface of the limit clip 10, making the clamping more stable. On the contrary, when loosening the limit, only need to turn the turntable 4 clockwise to release the limit. By this method, after sampling, the upper part of the first sampling cylinder 1 can be limited, so that the device will not leak liquid after sampling, effectively avoiding the problem that the detection work cannot proceed smoothly due to liquid leakage.

[0034] Embodiment 2, as Figure 1 - Figure 4 shown, a second sampling cylinder 2 is arranged below the first sampling cylinder 1. The upper end of the second sampling cylinder 2 is fixedly connected with a connecting cylinder 18. The inner surface of the second sampling cylinder 2 is threadedly connected with the lower end of the first sampling cylinder 1. The lower end of the first sampling cylinder 1 is fixedly connected with a sealing ring 15. A sealing groove 17 is opened at the upper end of the second sampling cylinder 2. The outer surface of the sealing ring 15 is inserted into the sealing groove 17. A protective cover 3 is threadedly connected to the lower end of the second sampling cylinder 2. A sampling needle 16 is fixedly communicated with the lower end of the second sampling cylinder 2. A suction mechanism 14 is arranged inside the first sampling cylinder 1. The outer surface of the suction mechanism 14 is threadedly connected with the upper part of the first sampling cylinder 1. The upper end of the suction mechanism 14 is fixedly connected with a handle 9. Anti-slip sheets 20 are uniformly fixedly connected around the turntable 4.

[0035] In this embodiment, when the first sampling cylinder 1 needs to be cleaned after the device is used, only by rotating the first sampling cylinder 1 and the second sampling cylinder 2 to separate them can the inside of the first sampling cylinder 1 be quickly cleaned. And a sealing ring 15 is fixed at the connection between the first sampling cylinder 1 and the second sampling cylinder 2, and the sealing ring 15 can be inserted into the sealing groove 17. In fact, when the first sampling cylinder 1 and the second sampling cylinder 2 are in normal use, their sealing performance is better. By this method, the cleaning of the device after use can be made more convenient, avoiding the problem of detection data deviation caused by improper cleaning of the device.

[0036] Working principle: When the device is in use, first remove the protective cover 3 from below the second sampling cylinder 2, and then rotate the handle 9 to drive the suction mechanism 14 to slide upward to suck the liquid to be detected into the first sampling cylinder 1. Then hold the outside of the first sampling cylinder 1 by hand and rotate the turntable 4 counterclockwise with the other hand. The sliding rod 13 on the limit clip 10 will move from one side inside the second sliding hole 12 to the other side. At the same time, the two limit clips 10 will also gather inward to perform the limit clamping function. At the same time, the limit leather pad 19 provided on the limit clip 10 can effectively increase the friction of the contact surface of the limit clip 10 to make the clamping more stable. On the contrary, when releasing the limit, only by rotating the turntable 4 clockwise can the limit be released. When cleaning the device, only by rotating the first sampling cylinder 1 and the second sampling cylinder 2 to separate them can the inside of the first sampling cylinder 1 be quickly cleaned.
