[0002] Quality inspection is crucial in the production of sprays, and accurate sampling is the foundation for ensuring reliable test results. After the spray production is completed, staff will use a sampling device to take a small amount of spray stored in the collection box for testing to check the quality of the spray.

[0003] In current technologies, some sampling devices for testing the production of sprays involve inserting their pipes into a collection box, then pulling a piston on the inner wall of the sampling device to use suction to remove the spray from the collection box.

[0004] However, when using this sampling device, after taking out a portion of the spray, it is necessary to push the spray out of the sampling device and place it in the sampling tank for later testing. During sampling, multiple sets of samples may need to be taken for testing and comparison. This causes the operator to repeatedly control the position of the sampling device during operation, which is too cumbersome and has low practicality. Therefore, in order to address the above problems, a sampling device for spray production testing is proposed. Summary of the Invention

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please refer to Figures 1-5. This utility model provides a sampling device for testing spray production, including a sampling cylinder 1; a sampling pipe 2 is fixedly connected to the inner wall of one end of the sampling cylinder 1; a discharge pipe 7 is fixedly connected to the side wall of the sampling pipe 2; a second air hole 9 is opened at one end of the sampling cylinder 1; a pull rod 4 is slidably connected to the other end of the sampling cylinder 1; a piston block 41 is fixedly connected to the end of the pull rod 4; the piston block 41 is piston-connected to the inner wall of the sampling cylinder 1; multiple sets of first air holes 47 are opened on the outer edge of the piston block 41; a sealing rod 49 is in contact with the inner wall of the first air hole 47; a fixing plate 5 is fixedly connected to the outer wall of the discharge pipe 7; the fixing plate 47 is fixedly connected to the outer wall of the discharge pipe 7; the second air hole 9 is vented into the sampling cylinder 1. An elastic telescopic rod 51 is fixedly connected to the bottom of the fixed plate 5; a support plate 52 is fixedly connected to the bottom of the elastic telescopic rod 51; a friction pad 54 is fixedly connected to the top of the support plate 52; a sampling canister 53 is in contact with the top of the friction pad 54; a sealing block 44 is in contact with the inner wall of the end of the sampling pipe 2; the sealing block 44 slides in the middle of the sampling cylinder 1; during operation, when the operator needs to sample the spray, they can pull the support plate 52, which will cause the elastic telescopic rod 51 to stretch elastically. After stretching to a certain extent, the sampling canister 53 can be placed on the center of the friction pad 54. Then, the support plate 52 is released, and the elastic... The telescopic rod 51 will reposition itself by pulling the support plate 52 through its elasticity. The support plate 52 will then move the sampling container 53, causing the top of the sampling container 53 to contact the friction pad 54 fixed to the bottom of the fixing plate 5, thus fixing the sampling container 53 in place. Then, simply place the liquid suction end of the sampling pipe 2 into the spray and repeatedly push and pull the lever 4. The lever 4 will cause the piston block 41 to move within the inner wall of the sampling cylinder 1. When the piston block 41 moves inside the sampling cylinder 1, it will cause the air inside the sampling cylinder 1 and the sampling pipe 2 to flow. During this process, the sealing block 44 will repeatedly detach and insert for sampling. The sealing rod 49 at the end of pipe 2 will repeatedly detach from and insert into the inner wall of the air hole 47, and the sealing block 44 and the sealing rod 49 will move alternately. This will allow the air inside the sampling cylinder 1 and the sampling pipe 2 to be discharged, and the spray to be carried into the inner wall of the sampling pipe 2. When the spray flows inside the sampling pipe 2, it will flow into the sampling tank 53 along the discharge pipe 7, thus completing the sampling. After the sampling tank 53 is full, it can be removed and replaced with a new sampling tank 53 to continue sampling. There is no need to repeatedly move the sampling device to collect and discharge materials, which improves convenience.

[0027] Furthermore, as shown in Figures 1 and 4, a baffle 3 is fixedly connected to the outer wall of the sampling pipe 2; a fixing block 6 is fixedly connected to the bottom of the support plate 52; a round rod 62 is slidably connected to the middle of the fixing block 6; a top plate 61 is fixedly connected to the end of the round rod 62; a moving plate 63 is fixedly connected to the other end of the round rod 62; and the top of the moving plate 63 is slidably connected to the bottom of the support plate 52. During operation, when sampling, the side wall of the baffle 3 can be made to contact the inner wall of the spray collection box. Then, the threaded rod 64 can be rotated to control the moving plate 63, which is threadedly connected to its outer wall, to move. The moving plate 63 will drive the round rod 62 to move, and the round rod 62 will move the top plate 61 until the top plate 61 is in contact with the outer wall of the spray collection box and, together with the baffle 3, fixes the entire device on the collection box. Then, the rotation of the threaded rod 64 can be stopped. In this way, the user does not need to control the sampling device with both hands and can perform sampling with one hand, which improves convenience.

[0028] Furthermore, as shown in Figure 2, a groove 8 is provided on the inner wall of the sampling cylinder 1; a slider 45 is elastically connected to the inner wall of the groove 8 via a spring 46; the side wall of the end of the slider 45 is slidably connected to the inner wall of the groove 8; one end of the spring 46 is fixed to the side wall of the slider 45; the other end of the spring 46 is fixed to the inner wall of the groove 8. During operation, when the piston block 41 moves, it will drive the airflow between the sampling cylinder 1 and the inner wall of the sampling pipe 2, causing the sealing block 44 to move. The sealing block 44 disengages from the inner wall of the end of the sampling pipe 2. At this time, the sealing block 44 will... The slider 45 slides along the inner wall of the groove 8. At the same time, the slider 45 compresses the second spring 46. When pushed, the air inside the sampling cylinder 1 causes the sealing rod 49 to disengage from the inner wall of the air hole 47. At this time, the second spring 46 pushes the slider 45 and the sealing block 44 to move and reset through its own elasticity, so that the sealing block 44 is inserted into the inner wall of the end of the sampling pipe 2, ensuring that the air inside the sampling pipe 2 does not change, and ensuring that the position of the spray inside the sampling pipe 2 can be maintained. By repeatedly pulling the lever 4, the spray can be extracted, which improves practicality.

[0029] Furthermore, as shown in Figures 2 and 3, a ring 43 is fixedly connected to the outer wall of the pull rod 4; a sliding ring 48 is slidably connected to the outer wall of the pull rod 4; a spring 42 is sleeved on the outer wall of the pull rod 4; one end of the spring 42 is fixedly connected to the end of the ring 43; the other end of the spring 42 is fixedly connected to the end of the sliding ring 48; and the sealing rod 49 is fixedly connected to the other end of the sliding ring 48. During operation, when the pull rod 4 is pushed, the suction force on the sealing block 44 decreases, and it will reset under the elastic action of the spring 46. At this time, the air inside the sampling cylinder 1 will not flow into the inner wall of the sampling pipe 2, but can only pass through the air hole 47 and push the sealing rod 49 to disengage it from the inner wall of the air hole 47. In this way, the excess air inside the sampling cylinder 1 can be discharged through the air hole 9, ensuring that the spray can be extracted smoothly and improving practicality.

[0030] Furthermore, as shown in Figures 4 and 5, multiple sets of friction pads 54 are provided; multiple sets of friction pads 54 are fixed to the bottom of the fixing plate 5. During operation, the surface of the friction pads 54 has a certain roughness to ensure the stability of the sampling canister 53 when placed on it. Although the multiple sets of friction pads 54 are in contact with the top of the sampling canister 53, there is a certain slight gap, which reduces the risk of the sampling pipe 2 being drawn into a vacuum and ensures that when the spray passes through the discharge pipe 7, it can flow into the interior of the sampling canister 53.

[0031] Furthermore, as shown in Figures 1 and 4, the side wall of the fixed block 6 is rotatably connected to a threaded rod 64; the outer wall of the threaded rod 64 is threadedly connected to the inner wall of the moving plate 63. During operation, the thread between the threaded rod 64 and the moving plate 63 has an axial self-locking characteristic, ensuring that the moving plate 63 will not be displaced when the threaded rod 64 is not rotated, thus ensuring the stability of the entire device fixed on the collection box.

[0032] Furthermore, as shown in Figure 4, multiple sets of the round rods 62 are provided; and the multiple sets of round rods 62 are symmetrically arranged with the center line of the fixing block 6 as the axis of symmetry. During operation, by setting multiple sets of round rods 62, the stability of the support for the top plate 61 can be improved, and the stability of the entire device is also improved accordingly.

[0033] Working principle: When staff need to sample the spray, they can pull the support plate 52. The support plate 52 will then cause the elastic telescopic rod 51 to stretch elastically. After stretching to a certain extent, the sampling canister 53 can be placed on the center of the friction pad 54. Then, the support plate 52 is released. The elastic telescopic rod 51 will then pull the support plate 52 back to its original position through its elasticity. The support plate 52 will then move the sampling canister 53, causing the top of the sampling canister 53 to contact the friction pad 54 fixed to the bottom of the fixing plate 5. This will fix the sampling canister 53 in place. Then, simply place the suction end of the sampling pipe 2 into the spray and repeatedly push and pull the lever 4. The lever 4 will cause the piston block 41 to move within the sampling cylinder 1. When the air is in the sampling tube 1 and the sampling pipe 2, the air inside the sampling tube 1 and the sampling pipe 2 will flow. During this process, the sealing block 44 will repeatedly detach from and insert into the inner wall of the end of the sampling pipe 2, and the sealing rod 49 will repeatedly detach from and insert into the inner wall of the air hole 47. The sealing block 44 and the sealing rod 49 move alternately. This will expel the air inside the sampling tube 1 and the sampling pipe 2 and bring the spray into the inner wall of the sampling pipe 2. When the spray flows inside the sampling pipe 2, it will flow into the sampling tank 53 along the discharge pipe 7. This will complete the sampling. After the sampling tank 53 is full, it can be removed and replaced with a new sampling tank 53 to continue sampling. There is no need to repeatedly move the sampling device to collect and discharge the material, which improves convenience.

[0034] During sampling, the side wall of the baffle 3 can be made to contact the inner wall of the spray collection box. Then, the threaded rod 64 can be rotated to control the moving plate 63, which is threaded to its outer wall, to move. The moving plate 63 will drive the round rod 62 to move, and the round rod 62 will move the top plate 61 until the top plate 61 is in contact with the outer wall of the spray collection box. Together with the baffle 3, the entire device is fixed on the collection box. Then, the rotation of the threaded rod 64 can be stopped. In this way, the user does not need to control the sampling device with both hands and can perform sampling with one hand, which improves convenience.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
