Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a sampling device. Background Art

[0002] Food testing is the process of conducting a series of analyses and tests on food samples to evaluate various indicators such as food quality, safety, nutritional value, etc. The purpose is to ensure the safety, nutrition and reliability of food, thereby protecting public health.

[0003] In food testing, sampling is a key link. Whether the sampling is standardized is related to the validity of the food testing results. With the development of society, there are many kinds of food sold on the market, but they can be roughly divided into two categories: liquid food and solid food. For solid food sampling, it is only necessary to directly extract and cut to obtain food samples, while for liquid food sampling, the method of pouring or scooping is usually adopted. However, when the liquid food packaging container is large, the pouring or scooping method has the disadvantages of being difficult to operate and difficult to ensure uniform sampling. In view of this, the present application proposes a sampling device. Utility Model Content

[0004] The utility model aims to provide a sampling device which is suitable for sampling liquid food and has a simple overall structure and is easy to operate.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sampling device comprises a mounting plate; a sampling tube spirally mounted on the bottom of the mounting plate, the top of the sampling tube passing through the mounting plate; a screw rod passing through the top of the sampling tube, a piston adapted to the sampling tube being fixed at the bottom of the screw rod.

[0007] Through the above-mentioned structural method, the sampling tube is inserted into the liquid food by utilizing the cooperation between the piston and the sampling tube. The piston is driven upward by the upper drawing rod to suck the liquid food into the sampling tube, thereby realizing the sampling of the liquid food. The sampling tube can be extended into different positions in the liquid food, and the sampling can be performed in layers to ensure the uniformity of the sample, thereby solving the problem of difficult sampling of liquid food.

[0008] Preferably, a handle is connected to the top end of the screw rod, and a grip is vertically fixed to one end of the mounting plate.

[0009] Preferably, one end of the mounting plate away from the handle is hinged with a connecting arm, and a suction cup is mounted on the connecting arm.

[0010] Preferably, a shell cover is fixed on the mounting plate, the screw rod movably passes through the top surface of the shell cover, a sleeve is rotatably mounted on the inner top wall of the shell cover, the sleeve is threadedly engaged with the screw rod, and a rotating handle for driving the sleeve to rotate is installed on the side wall of the shell cover.

[0012] Through the above-mentioned structural manner, the rotating handle is rotated, and the cooperation of the active bevel gear and the driven bevel gear is utilized to drive the sleeve to rotate. The sleeve drives the lead screw to drive the piston to move upward, so that the liquid food can be sucked into the sampling tube. The rotating handle is rotated in the opposite direction to drive the lead screw to move downward, so that the food sample extracted from the sampling tube can be discharged and collected, and the liquid sampling operation is completed, thereby solving the problem that it is difficult to operate by directly pulling the lead screw to rise and fall.

[0013] Preferably, a push rod is movably provided on the handle at a position horizontally aligned with the driven bevel gear, the push rod movably passes through the side wall of the shell cover at one end facing the shell cover and is connected to a rubber block, an end plate is fixed to the end of the push rod away from the rubber block, and a spring is sleeved on the push rod located between the end plate and the handle.

[0014] Preferably, a limiting guide plate is provided on the inner wall of the sampling tube along the length direction, and a limiting groove which fits in with the limiting guide plate is provided on the piston.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model arranges the screw rod and the mounting plate, and the sampling tube is inserted into the liquid food packaging container to be sampled by holding the grip, and the screw rod is driven to drive the piston upward by rotating the rotary handle, utilizing the cooperation of the active bevel gear and the driven bevel gear, and the threaded sleeve cooperation of the sleeve and the screw rod, so that the liquid food can be sucked into the sampling tube. After the sampling tube is drawn out of the food, the rotary handle is rotated in the opposite direction to drive the screw rod downward, and the food sample drawn in the sampling tube can be discharged and collected, thereby realizing the sampling operation of liquid food. Moreover, the sampling tube can be extended into different positions in the liquid food, and sampling can be carried out in layers to ensure the uniformity of the sample. The overall structure is simple and reasonable, and the problem of difficult sampling of liquid food is solved.

The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0026] Example

[0027] See also Figures 1 to 5 , the utility model preferably provides a technical solution:

[0028] A sampling device comprises a mounting plate 1; a sampling tube 2 spirally mounted on the bottom of the mounting plate 1, the top of the sampling tube 2 passing through the mounting plate 1; a screw rod 3 passing through the top of the sampling tube 2, the bottom of the screw rod 3 being fixed with a piston 14 adapted to the sampling tube 2, the sampling tube 2 is inserted into liquid food by the cooperation of the piston 14 and the sampling tube 2, the piston 14 is driven upward by pulling the screw rod 3, the liquid food can be sucked into the sampling tube 2, and the sampling of the liquid food is realized, and the sampling tube 2 can be extended into different positions in the liquid food, and the sampling can be layered to ensure the uniformity of the sample, thereby solving the problem of difficult sampling of liquid food.

[0029] In this embodiment, a handle 6 is vertically fixed at one end of the mounting plate 1, which is used to hold and support the sampling tube 2 and the mounting plate 1 for sampling operation. A connecting arm 7 is hinged at one end of the mounting plate 1 away from the handle 6, and a suction cup 8 is installed on the connecting arm 7. The suction cup 8 is adsorbed on the wall of the liquid food packaging container to assist in supporting the mounting plate 1 and the sampling tube 2, so as to facilitate a smooth sampling operation.

[0030] As a preferred implementation of this embodiment, a shell cover 5 is fixed on the mounting plate 1, and the screw rod 3 is movable through the top surface of the shell cover 5. A sleeve 13 is rotatably mounted on the inner top wall of the shell cover 5, and the sleeve 13 is threadedly sleeved with the screw rod 3. A rotating handle 10 for driving the sleeve 13 to rotate is mounted on the side wall of the shell cover 5. A driven bevel gear 11 is fixedly sleeved on the sleeve 13, and an active bevel gear 12 is rotatably mounted on the inner side wall of the shell cover 5. The active bevel gear 12 is meshed with the driven bevel gear 11. The rotating handle 10 is coaxially connected with the active bevel gear 12. The rotating handle 10 is rotated, and the sleeve 13 is driven to rotate by the cooperation of the active bevel gear 12 and the driven bevel gear 11. The sleeve 13 drives the screw rod 3 to drive the piston 14 to move upward. At this time, the liquid food can be sucked into the sampling tube 2. The rotating handle 10 is rotated in the opposite direction to drive the screw rod 3 to move downward, so that the food sample extracted from the sampling tube 2 can be discharged and collected, and the liquid sampling operation is completed, solving the problem that it is difficult to operate by directly pulling the screw rod 3 up and down.

[0031] Furthermore, a push rod 9 is movably provided at a position on the handle 6 that is horizontally aligned with the driven bevel gear 11. The end of the push rod 9 that faces the shell cover 5 movably passes through the side wall of the shell cover 5 and is connected to a rubber block 19. An end plate 17 is fixed to the end of the push rod 9 that is away from the rubber block 19. A spring 18 is sleeved on the push rod 9 between the end plate 17 and the handle 6. After the liquid food sample is sucked into the sampling tube 2, the end plate 17 is pressed to move the push rod 9 so that the rubber block 19 abuts against the driven bevel gear 11, and the driven bevel gear 11 and the sleeve 13 can be rotated to position to prevent the screw rod 3 from moving up and down and causing the sample to fall. After the end plate 17 is loosened, the spring 18 can use the elastic force to push the end plate 17 to drive the push rod 9 to separate the rubber block 19 from the driven bevel gear 11.

[0032] Furthermore, a handle 4 is connected to the top of the screw rod 3, and the handle 4 can limit the top of the screw rod 3 to prevent the screw rod 3 from completely extending into the sampling tube 2, and when the piston 14 is at the bottom, holding the handle 4 can facilitate the shoelace of the sampling device. A limit guide plate 15 is provided on the inner wall of the sampling tube 2 along the length direction, and a limit groove 16 is provided on the piston 14 to fit with the limit guide plate 15. The limit groove 16 and the limit guide plate 15 are slidably engaged to limit the axial position of the screw rod 3 and the piston 14, so as to prevent the screw rod 3 from rotating with the sleeve 13, and ensure that the rotation of the sleeve 13 can smoothly drive the screw rod 3 to rise and fall.

[0033] When in use, the grip 6 is held to insert the sampling tube 2 into the liquid food packaging container to be sampled, and the sleeve 13 is driven to rotate by rotating the rotary handle 10 and utilizing the cooperation of the active bevel gear 12 and the driven bevel gear 11. The sleeve 13 drives the screw rod 3 to drive the piston 14 to move upward, and the liquid food can be sucked into the sampling tube 2. Then, the end plate 17 is pressed to push the push rod 9 so that the rubber block 19 abuts against the driven bevel gear 11, and the driven bevel gear 11 and the sleeve 13 are rotated and positioned to prevent the screw rod 3 from moving up and down. After the sampling tube 2 is pulled out of the food, the end plate 17 is released and the rotary handle 10 is rotated in the opposite direction to drive the screw rod 3 to move downward, so that the food sample extracted from the sampling tube 2 can be discharged and collected, and the liquid sampling operation is completed. Furthermore, during the sampling process, the suction cup 8 is adsorbed on the wall of the liquid food packaging container to provide auxiliary support for the mounting plate 1 and the sampling tube 2 to facilitate a smooth sampling operation.
