[0004] However, the device still has the following problems: When sampling waterproof materials at different depths, it is necessary to go deep into the sampling location. After sampling, the waterproof material may stick to the outer wall of the sampling device, and the adhesive material on the outer wall may leak everywhere. When sampling at different depths, the waterproof material is easily disturbed as the sample travels to different depths, resulting in inaccurate sampling depth. Summary of the Invention

[0005] To address the problems existing in the prior art, a sampling device for the production of concrete waterproofing agents is provided to solve the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a sampling device for concrete waterproofing agent production, including a cylinder. The cylinder has a sampling hole that matches a sampling port in the tank. The sampling port can be opened and closed. A liquid extraction component for extracting waterproofing agent from the tank is provided inside the cylinder. A locking rod that can lock the liquid extraction component is slidably provided on one side of the cylinder. A magnetic element that attracts the locking rod is provided on the sampling port. When the sampling port is opened, the magnetic element cooperates with the locking rod to release the locking of the liquid extraction component.

[0007] Preferably, a fixing plate is fixed inside the sampling port, the fixing plate has a first through hole, a sealing plate is rotatably disposed on the fixing plate, and a second through hole is provided on the sealing plate. When the first through hole and the second through hole are misaligned, the sampling port is closed; when the first through hole and the second through hole coincide, the sampling port is opened.

[0008] Preferably, a rod is slidably connected to the sealing plate, and an insertion hole is provided on the fixing plate for the rod to slide freely into. The rod is connected to the sealing plate through a first tension spring, and a magnet that attracts the rod is fixed on the cylinder. The magnetic force of the magnet is greater than the elastic force of the first tension spring.

[0009] Preferably, one side of the sealing plate protrudes outward to form a protrusion, and the cylinder has a groove for the protrusion to slide freely into.

[0010] Preferably, the protrusion has a space for the insertion rod to slide freely, and the magnet is fixedly installed in the groove.

[0011] Preferably, a one-way valve is detachably connected inside the sampling hole, the one-way valve can slide freely into the second through hole, and a sealing ring is fitted on the one-way valve.

[0012] Preferably, the one-way valve is threaded into the sampling hole, and the distance between the end of the one-way valve and the end of the cylinder is equal to or less than the thickness of the sealing plate.

[0013] Preferably, a guide block is fixed inside the sampling port, and a sliding groove and a rotating groove that cooperate with the guide block are provided on the cylinder body, and the sliding groove and the rotating groove are connected.

[0015] Preferably, the sampling port is slidably connected to a positioning rod, the positioning rod passes through the side wall of the sampling port, the positioning rod is connected to the sampling port by a spring, and the cylinder has a positioning hole for the positioning rod to slide freely into.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention features a locking rod for locking the liquid extraction assembly and a magnetic component on the sampling port. When the cylinder is engaged with the sampling port, opening the sampling port simultaneously unlocks the liquid extraction assembly by engaging the locking rod. This ensures that the liquid extraction assembly can only begin operation after the sampling port is fully open, reducing the occurrence of insufficient sampling volume or leakage due to insufficient sampling port opening. Furthermore, it is easy to operate, eliminating the need for repeated observation and comparison by the user, effectively reducing the occurrence of misoperation.

[0017] This utility model is equipped with a rod and a magnet. The magnet will only attract the rod when it is inserted into the cylinder at the appropriate position, thereby releasing the lock on the sealing plate. This prevents the sealing plate from being opened by other devices or misoperation, which could lead to leakage of materials inside the tank and improves the safety of materials stored inside the tank.

[0018] The cylinder of this utility model has a sliding groove and a rotating groove. Since the sampling port is set outside the tank, there is no need to insert the cylinder into the waterproofing agent for sampling, so the state of the waterproofing agent inside the tank will not be disturbed. The sampling position is more accurate. At the same time, the waterproofing agent will not stick to the outer wall of the cylinder, so the waterproofing agent will not drip everywhere and cause pollution. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] refer to Figures 1-4 This embodiment proposes a sampling device for the production of concrete waterproofing agent, including a cylinder 3. The cylinder 3 has a sampling hole 4 that matches the sampling port 2 of the tank 1. The sampling port 2 can be opened and closed. The cylinder 3 is provided with a liquid extraction component for extracting waterproofing agent from the tank 1. A locking rod 5 that can lock the liquid extraction component is slidably provided on one side of the cylinder 3. A magnetic component that attracts the locking rod 5 is fixed on the sampling port 2. When the sampling port 2 is opened, the magnetic component cooperates with the locking rod 5 to release the locking of the liquid extraction component.

[0023] By inserting the cylinder 3 into the sampling port 2, the sampling hole 4 is matched with the sampling port 2. Then, by rotating the cylinder 3, the sampling port 2 is opened. When the sampling port 2 is fully opened, the magnetic component on the sampling port 2 is located on one side of the locking rod 5, which attracts the locking rod 5. The locking rod 5 releases the lock on the liquid extraction component, allowing the liquid extraction component to work and perform sampling.

[0024] The liquid extraction assembly is a piston 20. A sealing ring is fitted on the piston 20 to seal it with the cylinder 3. The piston 20 is slidably connected to the cylinder 3. A fixing rod is fixed on the piston 20. One end of the fixing rod extends out of the cylinder 3 to form a handle. The handle can pull the piston 20 to move inside the cylinder 3 to extract the waterproofing agent in the tank 1.

[0025] A fixing plate is fixed inside the sampling port 2. The fixing plate has a first through hole. A sealing plate 6 is rotatably installed on the fixing plate. A second through hole is opened on the sealing plate 6. When the first through hole and the second through hole are misaligned, the sampling port 2 is closed. When the first through hole and the second through hole coincide, the sampling port 2 is opened.

[0026] After the cylinder 3 slides into the sampling port 2, the front end of the cylinder 3 cooperates with the sealing plate 6, so that the cylinder 3 can drive the sealing plate 6 to rotate. Only when the cylinder 3 drives the sealing plate 6 to rotate until the first through hole and the second through hole coincide, the magnetic component is located on one side of the locking rod 5, thereby generating an attraction force on the locking rod 5, so that the locking rod 5 releases the piston 20 from locking.

[0027] Only after piston 20 is released from its locking position can it slide freely within cylinder 3, thereby extracting the waterproofing agent and taking a sample.

[0028] A rod 7 is slidably connected to the sealing plate 6. A hole is provided on the fixing plate for the rod 7 to slide freely into. The rod 7 is connected to the sealing plate 6 through a first tension spring 8. A magnet 9 that attracts the rod 7 is fixed on the cylinder 3. The magnetic force of the magnet 9 is greater than the elastic force of the first tension spring 8.

[0029] When the cylinder 3 slides into the sampling port 2 at the correct angle, the magnet 9 and the insertion rod 7 are on the same axis. The magnet 9 attracts the insertion rod 7, causing the insertion rod 7 to slide out of the insertion hole and approach the magnet 9. At this time, the first tension spring 8 is compressed.

[0030] When the angle of the cylinder 3 sliding into the sampling port 2 is offset, the sampling hole 4 and the second through hole do not coincide. Since the magnet 9 and the insertion rod 7 are not on the same axis at this time, the insertion rod 7 continues to be held in the insertion hole on the fixed plate under the action of the first tension spring 8, so that the fixed plate and the sealing plate 6 are kept locked, which can prevent the leakage of waterproofing agent during sampling due to the misalignment of the sampling hole 4 and the second through hole.

[0031] One side of the sealing plate 6 protrudes outward to form a protrusion, and a groove 10 is provided on the cylinder 3 for the protrusion to slide freely into.

[0032] When the protrusion slides into the groove 10, the cylinder 3 is rotated. The groove 10 on the cylinder 3 drives the sealing plate 6 to rotate through the protrusion, thereby opening and closing the sealing plate 6.

[0033] There are several protrusions and grooves 10, and each protrusion and groove 10 corresponds to another one.

[0034] The protrusion has a space for the insertion rod 7 to slide freely, and the magnet 9 is fixedly installed in the groove 10.

[0035] A one-way valve 11 is detachably connected inside the sampling hole 4. The one-way valve 11 can slide freely into the second through hole, and a sealing ring is fitted on the one-way valve 11.

[0036] The sealing ring ensures that after the one-way valve 11 slides into the second through hole, no waterproofing agent will flow out from the second through hole during sampling, thus preventing contamination.

[0037] The flow direction of the one-way valve 11 is that the material enters the cylinder 3 from the outside and cannot flow out of the cylinder 3 through the one-way valve 11.

[0038] The one-way valve 11 is threaded into the sampling hole 4. The distance between the end of the one-way valve 11 and the end of the cylinder 3 is equal to or less than the thickness of the sealing plate 6.

[0039] After sampling is completed, the sampled material can be poured out through the sampling port 2 by unscrewing the one-way valve 11, which is convenient for subsequent testing.

[0040] It is also possible to screw an end cap onto the other end of the cylinder 3, and then unscrew the end cap to allow the piston to slide out of the cylinder 3, making it convenient to pour materials.

[0041] A guide block 12 is fixed inside the sampling port 2, and a sliding groove 13 and a rotating groove 14 that cooperate with the guide block 12 are provided on the cylinder 3. The sliding groove 13 and the rotating groove 14 are connected.

[0042] When the cylinder 3 slides into the sampling port 2, if the guide block 12 does not slide into the sliding groove 13, the cylinder 3 will not be able to continue to penetrate the sampling port 2, and the sampling port 2 will not open or close. This helps to keep the sampling port 2 closed and reduces the occurrence of leakage caused by misoperation.

[0043] After the guide block 12 slides normally through the sliding groove 13, it can no longer slide after reaching the end of the sliding groove 13. At this time, by rotating the cylinder 3, the guide block 12 continues to slide along the rotating groove 14 until it reaches the end of the rotating groove 14. At this time, the magnetic component is located on one side of the locking rod 5.

[0044] Since the rotating groove 14 is arranged along the circumference of the cylinder 3, when the guide block 12 is located at the end of the rotating groove 14, the cylinder 3 cannot move along the axis. This helps to avoid the cylinder 3 sliding out of the sampling port 2 during sampling, which would cause the sampling hole 4 to fail to close in time.

[0045] The sliding groove 13 and the rotating groove 14 are combined to ensure that the cylinder can only cooperate with the sampling port 2 according to the prescribed action. At the same time, when the cylinder is disengaged from the sampling port 2, it also needs to slide out through the sliding groove 13 and the rotating groove 14 to restore the sealing plate 6 to its initial position. This reduces the occurrence of reduced sealing due to the sealing plate 6 not rotating into place, improves the sealing degree, and helps to reduce the need for repeated adjustments of the cylinder to cooperate with the sampling port 2 when sampling again.

[0046] The magnetic component is a magnetic block 15. The locking rod 5 is connected to the cylinder through a second tension spring 19. The magnetic force of the magnetic block 15 is greater than the elastic force of the second tension spring 19.

[0047] The sampling port 2 is slidably connected to a positioning rod 16, which passes through the side wall of the sampling port 2. The positioning rod 16 is connected to the sampling port 2 by a spring 17. The cylinder 3 has a positioning hole 18 for the positioning rod 16 to slide freely into.

[0048] After the sampling port 2 is fully opened in the cylinder 3, the positioning rod 16 is located at the upper end of the positioning hole 18. Under the action of the spring 17, the positioning rod can be pushed into the positioning hole 18 to lock the cylinder 3, so that the cylinder 3 will not fall off during sampling.

[0049] Several sampling ports 2 are provided in the vertical direction of the tank 1, which can facilitate sampling at different locations. Since the sampling ports 2 are set on the outside of the tank 1, there is no need to insert the cylinder 3 into the waterproofing agent for sampling, so the state of the waterproofing agent in the tank 1 will not be disturbed, the sampling position is more accurate, and the waterproofing agent will not stick to the outer wall of the cylinder 3, so the waterproofing agent will not drip everywhere and cause pollution.

[0050] A handle for easy gripping is also fixed on the cylinder body 3.

[0051] Specific working principle and usage process: After removing the cylinder 3, rotate the cylinder 3 so that the sliding groove 13 is in the upper position. Then select the sampling port 2 for this time, align the cylinder 3 with the sampling port 2, and slide the cylinder 3 into the sampling port 2 until it slides to the end of the sliding groove 13. At this time, the one-way valve 11 slides into the second through hole on the sealing plate 6, and the protrusion slides into the groove 10. The magnet in the groove 10 attracts the insertion rod 7, causing the insertion rod 7 to slide out from the insertion hole on the fixed plate and release the lock on the sealing plate 6. Rotate the cylinder 3 so that the guide block 12 continues to rotate along the rotating groove 14 until it slides to the end of the rotating groove 14. At this time, the positioning hole 18 is located below the positioning rod 16. Under the action of the spring 17, the positioning rod 16 slides into the positioning hole 18 to complete the locking of the cylinder 3. At the same time, the locking rod 5 rotates with the cylinder 3 to the upper end of the magnetic block 15. The magnetic block 15 attracts the locking rod 5, causing the locking rod 5 to slide away from one side of the piston 20 and no longer restrict the sliding of the piston 20. At this time, by using the handle to drive the piston 20, the sample of the waterproofing agent at that position can be extracted from the can 1.

[0052] After sampling is completed, manually pull out the positioning rod 16 and let it slide out of the positioning hole 18 to release the lock on the cylinder 3. Then rotate the cylinder 3 so that the guide block 12 slides along the rotating groove 14 until it reaches the front end of the rotating groove 14, which is the end of the sliding groove 13. While the cylinder 3 is rotating, the sealing plate 6 is driven to rotate through the groove 10 and the protrusion, so that the first through hole and the second through hole are misaligned, thus completing the closure and sealing of the sampling port 2. Continue to pull out the cylinder 3 so that the cylinder 3 is separated from the sampling port 2. At this time, the first tension spring releases its elasticity, which drives the insertion rod 7 to slide back into the insertion hole, thus completing the locking of the sealing plate 6 and completing this sampling.
