Description

Technical Field

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

[0002] Food testing is based on some basic theories and various technologies of physics, chemistry and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure product quality. Food inspection includes sensory testing of food, testing of nutrients, additives and harmful substances in food, etc. Sampling devices are required to take samples of food during food testing.

[0003] When using existing sampling devices, staff often find that in order to prevent cross-sample influence on data, the current liquid food sampling device needs to clean and disinfect the sampler after sampling before sampling again, which increases the time for multiple sampling and reduces the sampling efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a sampling device capable of quantitative sampling.

[0005] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solution: a sampling device capable of quantitative sampling, comprising a sampler, a piston is provided in the sampler, two pull rods are fixedly connected to the piston, a liquid storage structure is provided on the sampler, the liquid storage structure is mainly composed of a liquid storage tube, the liquid storage tube is provided on the sampler, five connecting rods are fixedly connected to the liquid storage tube, five connecting holes are opened on the sampler, and the connecting rods are adapted to the connecting holes.

[0006] The effect achieved by the above components is: when sampling, the four connecting rods are respectively inserted into the corresponding connecting holes, the liquid storage tube is connected to the sampler, and then the sampling end of the liquid storage tube is placed in the liquid food to be tested, and the two pull rods are pulled to drive the piston to rise, and then the liquid food to be tested is sucked into the liquid storage tube for storage, while the sampler remains clean and a new liquid storage tube can be replaced for secondary sampling, thereby avoiding the current liquid food sampling device. After sampling, the sampler needs to be cleaned and disinfected before sampling can be performed again, thereby increasing the time for multiple samplings and reducing the sampling efficiency.

[0007] Preferably, the sampler is provided with five fixing plates, and limiting rods are slidably inserted on the fixing plates. Limiting holes are provided on the connecting rods, and the limiting holes are adapted to the size of the limiting rods.

[0008] The effect achieved by the above components is: after the connecting rod is connected to the connecting hole, the limiting rod can be inserted into the limiting hole to enhance the connection effect.

[0009] Preferably, a sealing ring is fixedly connected to the liquid storage tube, and a sealing groove is provided on the sampler.

[0010] The effect achieved by the above components is: when connecting the sampler and the liquid storage tube, the sealing ring is inserted into the sealing groove to enhance the sealing of the connection and prevent leakage.

[0011] Preferably, a first rubber stopper is provided on the liquid storage tube, and a second rubber stopper is provided on the liquid storage tube.

[0012] The effect achieved by the above components is: after sampling is completed, the first rubber stopper is first inserted into the lower end of the liquid storage tube, then the liquid storage tube is separated from the sampler, and finally the second rubber stopper is inserted into the upper end of the liquid storage tube to prevent the sample in the liquid storage tube from leaking.

[0013] Preferably, the sampler is provided with a quantitative structure, which is mainly composed of two groups of scale lines, and the two groups of scale lines are respectively provided on the sampler and the liquid storage tube.

[0014] The effect achieved by the above components is that the amount of sampling can be accurately controlled by observing the scale lines on the liquid storage tube.

[0015] Preferably, a quantitative block is provided in the sampler, and the quantitative block is slidably connected to the two pull rods.

[0016] The effect achieved by the above components is: before sampling, slide the quantitative block to the corresponding scale line of the required sampling amount. When sampling, pull the piston until it contacts the quantitative block to stop sampling, making the quantitative operation more convenient and there is no need to keep staring at the scale line during the sampling process.

[0017] Preferably, a threaded rod is rotatably connected to the quantitative block, and the threaded rod is threadedly inserted into the sampler.

[0018] The effect achieved by the above components is that since the quantitative block slides on the upper limit of the two pull rods, rotating the threaded rod will drive the quantitative block to rise or fall, making the position of the quantitative block more stable.

[0019] Preferably, a connecting rod is fixedly connected to the two pull rods, and a clearance hole is opened on the connecting rod, and the clearance hole does not contact the threaded rod.

[0020] The effect achieved by the above components is that when the threaded rod is rotated, since the threaded rod and the clearance hole do not contact each other, the rotation of the threaded rod will not affect the connecting rod.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting up a liquid storage structure, when sampling, the four connecting rods are respectively inserted into the corresponding connecting holes, the liquid storage tube is connected to the sampler, and then the sampling end of the liquid storage tube is placed in the liquid food to be tested, and the two pull rods are pulled to drive the piston to rise, thereby sucking the liquid food to be tested into the liquid storage tube for storage, while the sampler remains clean, and a new liquid storage tube can be replaced for secondary sampling. When the connecting rods are connected to the connecting holes, the limiting rod can be inserted into the limiting hole, and the sampler can be kept clean. To enhance the connection effect, when connecting the sampler and the liquid storage tube, the sealing ring is inserted into the sealing groove to enhance the sealing of the connection and prevent leakage. After the sampling is completed, the first rubber stopper is inserted into the lower end of the liquid storage tube, and then the liquid storage tube and the sampler are separated, and finally the second rubber stopper is inserted into the upper end of the liquid storage tube to prevent the sample in the liquid storage tube from leaking out, thereby avoiding the situation in which the current liquid food sampling device needs to clean and disinfect the sampler after sampling before sampling again, thereby increasing the time for multiple samplings and reducing the sampling efficiency.

[0027] Example 1, as Figure 1 As shown, a sampling device capable of quantitative sampling includes a sampler 1, a piston 2 is provided in the sampler 1, and two pull rods 3 are fixedly connected to the piston 2.

[0028] Reference Figure 1-3The sampler 1 is provided with a liquid storage structure 4, which is mainly composed of a liquid storage tube 41. The liquid storage tube 41 is arranged on the sampler 1, and five connecting rods 42 are fixedly connected to the liquid storage tube 41. The sampler 1 is provided with five connecting holes 43, and the connecting rods 42 are adapted to the connecting holes 43. When sampling, the four connecting rods 42 are respectively inserted into the corresponding connecting holes 43 to connect the liquid storage tube 41 to the sampler 1, and then the sampling end of the liquid storage tube 41 is placed in the liquid food to be tested, and the two pull rods 3 are pulled to drive the piston 2 to rise, thereby sucking the liquid food to be tested into the liquid storage tube 41 for storage, while the sampler 1 remains clean and a new liquid storage tube 41 can be replaced for secondary sampling, thereby avoiding the need for the sampler 1 to be cleaned and disinfected after sampling in the current liquid food sampling device before sampling can be performed again, thereby increasing the time for multiple samplings and reducing the sampling efficiency. The sampler 1 is provided with five fixing plates 45, and a limiting rod 46 is slidably inserted on the fixing plate 45. A limiting hole 44 is provided on the connecting rod 42, and the limiting hole 44 is adapted to the size of the limiting rod 46. When the connecting rod 42 is connected to the connecting hole 43, the limiting rod 46 can be inserted into the limiting hole 44 to strengthen the connection effect. A sealing ring 47 is fixedly connected to the liquid storage tube 41, and a sealing groove 48 is provided on the sampler 1. When connecting the sampler 1 and the liquid storage tube 41, the sealing ring 47 is inserted into the sealing groove 48 to strengthen the sealing of the connection and prevent leakage. A first rubber stopper 49 is provided on the liquid storage tube 41, and a second rubber stopper 410 is provided on the liquid storage tube 41. After the sampling is completed, the first rubber stopper 49 is first inserted into the lower end of the liquid storage tube 41, and then the liquid storage tube 41 is separated from the sampler 1, and finally the second rubber stopper 410 is inserted into the upper end of the liquid storage tube 41 to prevent the sample in the liquid storage tube 41 from leaking.

[0029] Reference Figure 4 , a quantitative structure 5 is provided on the sampler 1, and the quantitative structure 5 is mainly composed of two groups of scale lines 55. The two groups of scale lines 55 are respectively provided on the sampler 1 and the liquid storage tube 41. The amount of sampling can be accurately controlled by observing the scale lines 55 on the liquid storage tube 41. A quantitative block 51 is provided in the sampler 1. The quantitative block 51 is slidably connected with the two pull rods 3. Before sampling, the quantitative block 51 is slid to the corresponding scale line 55 of the required sampling amount. When sampling, the sampling can be stopped by pulling the piston 2 until it contacts the quantitative block 51, which makes the quantitative operation more convenient and does not require constant sampling during the sampling process. Staring at the scale line 55, the quantitative block 51 is rotatably connected to a threaded rod 53, and the threaded rod 53 is threadedly inserted on the sampler 1. Since the quantitative block 51 slides on the upper limit of the two pull rods 3, rotating the threaded rod 53 will drive the quantitative block 51 to rise or fall, making the position of the quantitative block 51 more stable. The two pull rods 3 are jointly fixedly connected with a connecting rod 52, and a clearance hole 54 is provided on the connecting rod 52. The clearance hole 54 does not contact the threaded rod 53. When the threaded rod 53 is rotated, since the threaded rod 53 and the clearance hole 54 do not contact, rotating the threaded rod 53 will not affect the connecting rod 52.

[0030] Working principle: when sampling, insert the four connecting rods 42 into the corresponding connecting holes 43 respectively, connect the liquid storage tube 41 with the sampler 1, and then put the sampling end of the liquid storage tube 41 into the liquid food to be tested, pull the two pull rods 3 to drive the piston 2 to rise, and then suck the liquid food to be tested into the liquid storage tube 41 for storage, while the sampler 1 remains clean, and a new liquid storage tube 41 can be replaced for secondary sampling, thereby avoiding the current liquid food sampling device. After sampling, the sampler 1 needs to be cleaned and disinfected before sampling again, which increases the time for multiple samplings and reduces the sampling efficiency. When the connecting rod 42 is connected to the connecting hole 43, the limiting rod 46 can be inserted into the limiting hole 44 to strengthen the connection effect. When connecting the sampler 1 and the liquid storage tube 41, the sealing ring 47 is inserted into the sealing groove 48 to strengthen the sealing of the connection and prevent leakage. After sampling is completed, first insert the first rubber stopper 49 into the lower end of the liquid storage tube 41, then separate the liquid storage tube 41 from the sampler 1, and finally insert the second rubber stopper 410 into the upper end of the liquid storage tube 41 to prevent the sample in the liquid storage tube 41 from leaking. The sampling amount can be accurately controlled by observing the scale line 55 on the liquid storage tube 41. Before sampling, slide the quantitative block 51 to the corresponding scale line 55 of the required sampling amount. When sampling, pull the piston 2 until it contacts the quantitative block 51 to stop sampling, making the quantitative operation more convenient. There is no need to keep staring at the scale line 55 during the sampling process. Since the quantitative block 51 slides on the upper limit of the two pull rods 3, rotating the threaded rod 53 will drive the quantitative block 51 to rise or fall, making the position of the quantitative block 51 more stable. When rotating the threaded rod 53, since the threaded rod 53 and the give way hole 54 do not contact, rotating the threaded rod 53 will not affect the connecting rod 52.
