Description

Technical Field

[0001] This utility model relates to the field of polyurethane detection and sampling, specifically a polyurethane detection and sampling device. Background Technology

[0002] Polyurethane is a polymer material made by reacting isocyanate with polyol. It has repeating urethane chain units and has a wide range of applications, including clothing and sports products (such as high-elasticity fibers, leather products, and sports shoe soles), daily necessities (such as furniture coatings, cushion materials, and food packaging adhesives), electronic products (such as adhesives in audio tapes, video tapes, and computer disks), medical devices (such as sealing materials for hollow filament bundles in artificial kidneys), automobiles and other transportation vehicles (such as tire chains and coatings), building and civil engineering (such as thermal insulation materials and exterior wall coatings), and industrial materials (such as conveyor belts, hoses, films, and membrane materials).

[0003] When testing and sampling polyurethane waterproof coatings, according to the inspection standards, it is necessary to sample and test the upper, middle and lower layers of polyurethane in the polyurethane container to ensure the accuracy of the sampling results. However, traditional sampling devices can only sample one layer at a time, which makes the sampling process cumbersome and cannot accurately control the sampling height. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane testing and sampling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane detection and sampling device, comprising an installation cylinder, three sets of lifting grooves on the outer side of the installation cylinder, a lifting block slidably connected inside the lifting grooves, an inner extrusion plate fixedly connected inside the lifting block, an outer installation plate fixedly connected outside the inner extrusion plate, a sampling cylinder fixedly connected outside the outer installation plate, a connecting hole at the lower part of the sampling cylinder, a plug rod slidably connected inside the sampling cylinder to the connecting hole, a threaded rod fixedly connected to the upper part of the plug rod, a fixing rod threadedly connected to the outer side of the threaded rod, and a pull plate fixedly connected to the upper part of the fixing rod.

[0006] Preferably, the external mounting plate has four sets of set screws internally threaded.

[0007] Preferably, the connecting hole has an installation groove inside, and a rubber ring is fixedly connected inside the installation groove.

[0008] Preferably, the sampling tube has an embedding groove inside that communicates with the connecting hole, and the lower outer side of the plug rod is fixedly connected to an embedding block that matches the embedding groove.

[0009] Preferably, the inner wall of the mounting cylinder has external friction textures, and the inner extrusion plate has internal friction textures on the side facing the inner wall of the mounting cylinder.

[0010] Preferably, three sets of mounting plates are fixedly connected to the lower inner side of the mounting cylinder, a mounting rod is fixedly connected inside the mounting plate, a lifting rod is slidably connected inside the mounting rod, and the upper part of the lifting rod is fixedly connected to the pulling plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a lifting block that moves up and down along a lifting groove to position three sampling cylinders at different locations via an external mounting plate, enabling simultaneous sampling of polyurethane acid at different depths. By rotating a top screw, the top screw presses against the outer wall of the mounting cylinder, and in conjunction with an inner extrusion plate, it presses against the inner wall of the mounting cylinder, thus fixing the installation height of the sampling cylinder. By rotating a threaded rod along the inside of a fixed rod, the length of the plug rod can be adjusted according to the height of the sampling cylinder, allowing the lower parts of the three plug rods to be simultaneously inserted into the connecting hole. When the device is inserted into the polyurethane tank, the pulling plate and fixed rod drive the plug rod to move up and down, causing the plug rod to disengage from the connecting hole, facilitating the entry of liquid into the sampling cylinder. This allows for simultaneous sampling of the liquid in the upper, middle, and lower layers of the polyurethane tank, and the position of each sampling cylinder can be adjusted according to the height of the tank to ensure sampling accuracy.

[0013] 2. This utility model also uses a rubber ring tightly attached to the outside of the plug rod, and an insert block inserted into the insert groove to limit the insertion depth of the plug rod, and can improve the sealing of the sampling tube, thus preventing liquid from leaking out of the sampling tube.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a polyurethane detection and sampling device, including an installation cylinder 1. Three sets of lifting grooves 2 are provided on the outer side of the installation cylinder 1. Lifting blocks 3 are slidably installed inside the lifting grooves 2. An inner extrusion plate 4 is fixedly welded inside the lifting block 3. An outer mounting plate 5 is fixedly welded to the outer side of the inner extrusion plate 4, preventing the lifting block 3 from detaching from the lifting groove 2. A sampling cylinder 6 is fixedly welded to the outer side of the outer mounting plate 5. By moving the lifting block 3 up and down along the lifting grooves 2, the three sets of sampling cylinders 6 are positioned at different locations via the outer mounting plate 5, enabling simultaneous sampling of polyurethane at different depths. The lower part of the sampling cylinder 6... A connecting hole 10 is provided. A plug rod 11 that matches the connecting hole 10 is slidably installed inside the sampling tube 6. A threaded rod 12 is fixedly welded to the upper part of the plug rod 11. A fixing rod 13 is threadedly connected to the outer side of the threaded rod 12. The threaded rod 12 rotates along the inside of the fixing rod 13, thereby adjusting the length of the plug rod 11 according to the height of the sampling tube 6, so that the lower parts of the three sets of plug rods 11 can be inserted into the connecting hole 10 at the same time. A pull plate 14 is fixedly welded to the upper part of the fixing rod 13. The pull plate 14 and the fixing rod 13 drive the plug rod 11 to move up and down, so that the plug rod 11 is disengaged from the connecting hole 10, which facilitates the liquid to enter the sampling tube 6.

[0020] The outer mounting plate 5 has four sets of set screws 7 internally threaded. By rotating the set screws 7, the set screws 7 press against the outer wall of the mounting cylinder 1, and together with the inner extrusion plate 4, press against the inner wall of the mounting cylinder 1, thus fixing the installation height of the sampling cylinder 6. The connecting hole 10 has a mounting groove 18 inside, and a rubber ring 19 is fixedly connected inside the mounting groove 18. The rubber ring 19 is tightly attached to the outside of the plug rod 11 to prevent leakage from the connecting hole 10. The sampling cylinder 6 has an embedding groove 20 inside that communicates with the connecting hole 10. An embedding block 21 that matches the embedding groove 20 is fixedly welded to the lower outer side of the plug rod 11 to limit the insertion depth of the plug rod 11. At the same time, the embedding block 21 is inserted into the groove 20. The rod is inserted into the embedding groove 20 to further improve the sealing performance of the plug rod 11; the inner wall of the mounting cylinder 1 is provided with external friction texture 8, and the inner extrusion plate 4 is provided with internal friction texture 9 on the side facing the inner wall of the mounting cylinder 1, so that when the inner extrusion plate 4 is in close contact with the inner wall of the mounting cylinder 1, the friction is increased, and the stability of the sampling cylinder 6 is further improved; three sets of mounting plates 16 are fixedly welded to the lower inner side of the mounting cylinder 1, and mounting rods 17 are fixedly welded inside the mounting plates 16. A lifting rod 15 is slidably connected inside the mounting rod 17. The upper part of the lifting rod 15 is fixedly welded to the pulling plate 14 to ensure that the pulling plate 14 is vertically up and down and to ensure the balance of the three sets of fixed rods 13.

[0021] Working principle: When in use, the lifting block 3 moves up and down along the lifting groove 2, and the three sampling cylinders 6 are positioned at different locations by the outer mounting plate 5, enabling simultaneous sampling of polyurethane acid at different depths. By rotating the top screw 7, the top screw 7 presses against the outer wall of the mounting cylinder 1, and the inner extrusion plate 4 presses against the inner wall of the mounting cylinder 1. The inner friction texture 9 and the outer friction texture 8 fix the installation height of the sampling cylinder 6. The threaded rod 12 rotates inside the fixing rod 13, thereby adjusting the length of the plug rod 11 according to the height of the sampling cylinder 6, so that the lower parts of the three plug rods 11 can be inserted into the connecting hole 10 at the same time. When the device is inserted into the polyurethane tank, the pulling plate 14 and the fixing rod 13 drive the plug rod 11 to move up and down, so that the plug rod 11 disengages from the connecting hole 10, facilitating the entry of liquid into the sampling cylinder 6.
