[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3As shown in the figure, the sampling device for engineering quality testing provided by this utility model includes a cylinder 1, a suction nozzle 2 connected to the top of the cylinder 1, a piston 4 disposed inside the cylinder 1, a connecting rod 3 fixed to the bottom outer wall of the piston 4, a pull ring 5 fixed to the bottom end of the connecting rod 3 extending to the outside of the cylinder 1, a scale 14 disposed on the outer wall of the cylinder 1, a connecting tube 6 fixed to the top outer wall of the cylinder 1, a threaded ring 9 integrally formed on the outer wall of the connecting tube 6, a connecting ring 17 integrally formed at the bottom of the suction nozzle 2, and the connecting ring 17 being threadedly connected to the threaded ring 9.

[0021] Specifically, in this embodiment, a cylindrical body 1 is included. The cylindrical body 1 is hollow inside and made of transparent material. A suction nozzle 2 is connected to the top of the cylindrical body 1. The suction nozzle 2 is conical. A piston 4 is provided inside the cylindrical body 1. A connecting rod 3 is fixed to the bottom outer wall of the piston 4. The piston 4 can be pulled by the connecting rod 3. The bottom end of the connecting rod 3 extends to the outside of the cylindrical body 1 and is fixed with a pull ring 5. The connecting rod 3 can be pulled by the pull ring 5. A scale 14 is provided on the outer wall of the cylindrical body 1. The scale 14 can easily display the volume of the paint sample taken inside the cylindrical body 1. A connecting tube 6 is fixed to the top outer wall of the cylindrical body 1. The connecting tube 6 communicates with the cylindrical body 1. A threaded ring 9 is integrally formed on the outer wall of the connecting tube 6. A connecting ring 17 is integrally formed on the bottom of the suction nozzle 2. The connecting ring 17 is threadedly connected to the threaded ring 9, so that the suction nozzle 2 can be easily assembled and disassembled with the connecting tube 6.

[0022] The present invention provides a sampling device for engineering quality testing. The piston 4 is pulled by the connecting rod 3, so that the waterproof coating can be sucked into the inside of the cylinder 1 during sampling, avoiding the phenomenon of spillage and dripping of the waterproof coating during sampling and filling, thus making the sampling of waterproof coating more convenient.

[0023] In another embodiment of this utility model, the top of the connecting pipe 6 is integrally formed with a tapered end 13, the outer wall of the tapered end 13 is provided with an annular groove 7, and a sealing ring 8 is provided inside the annular groove 7. The sealing ring 8 is frustoconical and located inside the suction nozzle 2. The sealing ring 8 is adapted to the suction nozzle 2, and the sealing effect between the suction nozzle 2 and the connecting pipe 6 is better through the sealing ring 8; a retaining ring 15 is fixed at the bottom of the cylinder 1, and a vent hole 12 is provided on the outer wall of the retaining ring 15. The vent hole 12 ensures that the piston 4 is not obstructed by air when it moves; A stud 10 is fixed to one side of the outer wall of the body 1.

The outer wall of the sealing cap 11 is provided with anti-slip texture 16. The sealing cap 11 is adapted to the threaded ring 9. At the same time, the sealing cap 11 can be threadedly connected to the threaded ring 9 to prevent the waterproof coating inside the cylinder 1 from flowing out from the connecting pipe 6.

[0024] Working principle: When it is necessary to sample the waterproof coating, first push the piston 4 to the end of the cylinder 1 near the suction nozzle 2 through the connecting rod 3. Then insert the suction nozzle 2 into the container containing the waterproof coating. Pull the connecting rod 3 through the pull ring 5, so that the connecting rod 3 drives the piston 4 to move away from the suction nozzle 2 inside the cylinder 1, thereby allowing the waterproof coating to be sampled to be sucked into the inside of the cylinder 1. Then, stand the suction nozzle 2 up and rotate it to separate the suction nozzle 2 from the connecting tube 6. Then, remove the sealing cap 11 from the stud 10, so that the sealing cap 11 is threadedly connected to the threaded ring 9 on the connecting tube 6, thereby sealing the connecting tube 6 and preventing the waterproof coating inside the cylinder 1 from flowing out.
