[0015] Please refer to Figures 1 to 3, A sampling device for detecting vehicle gasoline and diesel, including a sampler 1 and a protective structure 2 arranged on the sampler 1. The sampler 1 includes a sampling cylinder 3 with a sampling hole at the bottom, a boosting sleeve 4 arranged at the top of the sampling cylinder 3, a piston 5 arranged inside the sampling cylinder 3, a piston rod 6 vertically arranged on the piston 5, and a gripping handle 7 arranged at the upper end of the piston rod 6 and located above the sampling cylinder 3; The protective structure 2 includes a cylinder body 8 and a housing 9 arranged below the cylinder body 8 and closely attached to each other in a right triangle shape; A circular hole 10 with both ends connected is opened inside the cylinder body 8, and the sampling cylinder 3 is inserted into the circular hole 10. The cylinder body 8 is symmetrically provided with brackets in an L shape, and the opposite ends of the two housings 9 are hinged to the brackets. On the opposite sides of the inner walls of the two housings 9, a return spring 11 and a sponge pad 12 are arranged. The sponge pad 12 is located below the return spring 11, and the other end of the return spring 11 is arranged on the cylinder body 8.

[0016] In this embodiment: The lower end of the sampler 1 is inserted into the circular hole 10 inside the cylinder body 8. The protective structure 2 is placed at the sampling port position of the container filled with gasoline and diesel. The two brackets on the cylinder body 8 play a supporting role for the cylinder body 8 to prevent the housing 9 from contacting the gasoline and diesel container; Push the sampler 1 downward, the lower end of the sampler 1 passes through the cylinder body 8 and pushes open the two opposite housings 9. After the lower end of the sampler 1 passes through the sampling port and contacts the liquid to be collected, push the gripping handle 7, and the piston rod 6 pushes the piston 5 downward. The piston 5 moves to the bottom inside the sampling cylinder 3. Then pull the gripping handle 7, the piston 5 moves upward, and the sampling hole at the bottom of the sampling cylinder 3 generates suction, which can suck the liquid into the sampling cylinder 3 to achieve sampling; Pull the sampler 1 upward. When the bottom end of the sampler 1 moves into the cylinder body 8 and there is no obstacle between the two housings 9, the two housings 9 quickly move relative to each other and reset to be closely attached under the elastic force of the return spring 11. If there is liquid dripping below the sampler 1, the sponge layer inside the housing 9 can absorb the liquid to prevent the sample from dripping onto the table;

[0017] After the sampling liquid inside the sampler 1 of the present utility model is placed into the specified container, it can be inserted into the protective structure 2 again; At the same time, by inserting a new sampler 1, the oil liquid in another gasoline and diesel container can be collected;

[0018] The boosting sleeve 4 plays a limiting effect to prevent the sampler 1 from passing through the cylinder body 8 during sampling.

[0019] As a technical optimization scheme of the present utility model, a first spring 13 is arranged between the boosting sleeve 4 and the gripping handle 7.

[0020] In this embodiment: When sampling, the holding handle 7 is pressed, so that the pushing piston rod 6 drives the piston 5 to move downward. After the holding handle 7 is released, under the elastic force of the first spring 13, the holding handle 7 automatically returns to its original position. When the piston 5 moves upward, a suction force is generated at the sampling hole at the bottom of the sampling cylinder 3, and the liquid can be automatically drawn into the interior of the sampling cylinder 3. When sampling, there is no need to push and pull the holding handle 7, and the sampling is fast and convenient.

[0021] As a technical optimization scheme of the present utility model, a threaded sleeve 14 is provided below the assisting sleeve 4. The threaded sleeve 14 is arranged on the cylinder body 8 through threads. Connecting arms 15 are arranged on the outer walls of both the threaded sleeve 14 and the assisting sleeve 4, and a second spring 16 is arranged between the two connecting arms 15.

[0022] In this embodiment: The palms and limbs are attached to the lower connecting arm 15, and the upper connecting arm 15 is pressed. When the upper connecting arm 15 moves closer to the lower connecting arm 15 and moves downward, the sampler 1 is simultaneously pulled downward, so that the lower end of the sampler 1 passes through the cylinder body 8 and pushes open the two opposite shells 9. After the lower end of the sampler 1 contacts the liquid to be collected through the sampling port, while the palm does not loosen the connecting arm 15, the thumb presses the holding handle 7 once. When the holding handle 7 moves downward, the pushing piston rod 6 drives the piston 5 to move downward. After the holding handle 7 is released, under the elastic force of the first spring 13, the holding handle 7 automatically returns to its original position, and the liquid can be automatically drawn into the interior of the sampling cylinder 3 to complete the sampling; after the sample collection is completed, the upper connecting arm 15 is released together, and the sampler 1 automatically returns to its original position under the elastic force of the second spring 16. The two shells 9 quickly move relative to each other and return to be closely attached under the elastic force of the return spring 11. If there is liquid dripping below the sampler 1, the sponge layer inside the shell 9 can adsorb the liquid, preventing the sample from dripping onto the table, and the sampling can be easily completed.

[0023] As a technical optimization scheme of the present utility model, both the sampling cylinder 3 and the cylinder body 8 are made of transparent materials.

[0024] In this embodiment: Both the sampling cylinder 3 and the cylinder body 8 are made of transparent materials, and the oil liquid collected inside the sampling cylinder 3 can be visually seen.

[0025] Working principle: First, insert the lower end of the sampler 1 into the circular hole 10 inside the cylinder body 8, rotate the sampler 1, set the threaded sleeve 14 on the cylinder body 8, place the protection structure 2 at the sampling port position of the container filled with gasoline and diesel, support the bottom of the protection structure 2 empty by the bracket, press the upper connecting arm 15. When the upper connecting arm 15 moves downward, the lower end of the sampler 1 passes through the cylinder body 8 and pushes open the two opposite shells 9. After the lower end of the sampler 1 passes through the sampling port and contacts the liquid to be collected, press the holding handle 7, and then release it. Under the elastic force of the first spring 13, the holding handle 7 automatically resets, and the liquid can be automatically drawn into the sampling cylinder 3 to complete the sampling. After the sample collection is completed, release the upper connecting arm 15 together. The sampler 1 automatically resets under the elastic force of the second spring 16, and the two shells 9 quickly move relatively and reset tightly under the elastic force of the reset spring 11. If there is liquid dripping below the sampler 1, the sponge layer inside the shell 9 can absorb the liquid to prevent the sample from dripping onto the tabletop.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
