Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a food quality detection sampling device, including a sampling tube 1. A piston seat 9 is slidably connected inside the sampling tube 1. A pull rod 12 is fixedly installed at the top end of the piston seat 9. Slide frames 3 are fixedly installed on both sides of the sampling tube 1. Sliding plates 7 are slidably connected inside the two slide frames 3. Sampling heads 2 are fixedly installed on one side close to each other at the bottom ends of the two sliding plates 7. Pressing frames 10 are fixedly installed at the top ends of the two slide frames 3. Pressing seats 11 are arranged at the top ends of the two pressing frames 10. An installation frame 14 is fixedly installed at the rear end of the sampling tube 1. A threaded rod 16 is rotatably connected inside the installation frame 14. A U-shaped frame 15 is sleeved on the threaded rod 16. The two output ends of the U-shaped frame 15 are respectively fixedly installed on the two pressing seats 11. Springs 8 are fixedly installed on one side away from each other of the two sliding plates 7. The two springs 8 are fixedly installed on the inner walls of the slide frames 3 on one side away from each other. A suction pipe 6 is fixedly installed at the bottom end of the sampling tube 1.

[0022] A first bevel gear 18 is sleeved on the outer side of the top end of the threaded rod 16. The rear end of the first bevel gear 18 is meshed with a second bevel gear 17. Through this design, it is beneficial to the use of this device. A crank 19 is rotatably connected to the rear end of the installation frame 14. The front end of the crank 19 is fixedly installed on the first bevel gear 18. Driving the first bevel gear 18 to rotate through the crank 19 is beneficial to the use of this device. Air holes 13 are arranged on the top end of the sampling tube 1 outside the pull rod 12. By reserving the air holes 13, it is convenient for air intake and exhaust. Sampling cavities 4 are arranged inside the two sampling heads 2. By means of the sampling cavities 4, it is convenient to grab solid food samples. The bottom ends of the two sampling heads 2 are both provided with conical heads 5. By means of the conical heads 5, it is convenient to break the fixed food. Limit frames 21 are fixedly installed on the front parts of the two slide frames 3 on both sides of the sampling tube 1 and located on both sides of the two pressing seats 11. Sliders 20 are fixedly installed at the front ends of the two pressing seats 11. The two sliders 20 are respectively slidably connected inside the corresponding limit frames 21. The pressing seats 11 can be limited by the sliders 20.

[0023] Working principle: When in use, when it is necessary to collect solid food, the conical heads 5 at the bottoms of the two sampling heads 2 can be used to break the solid food. Then, the crank 19 is used to drive the second bevel gear 17, the first bevel gear 18 and the threaded rod 16 to rotate. At this time, the U-shaped frame 15 drives the two extrusion seats 11 to slide downward, so as to push the two extrusion frames 10 away from each other. The two extrusion frames 10 drive the two sampling heads 2 to slide away from each other and open. Then, the two sampling heads 2 are sleeved outside the solid food to be sampled. Then, the crank 19 is used to drive the second threaded rod 16 to reverse. At this time, the two extrusion seats 11 rise, and the two springs 8 drive the two extrusion frames 10 and the slide plate 7 to reset, so as to clamp and collect the solid food into the sampling cavity 4. When it is necessary to collect liquid food, the above principle can be used to first open the two sampling heads 2, then insert the straw 6 into the liquid food, and use the pull rod 12 to drive the piston seat 9 to rise, so that negative pressure is generated at the straw 6 to suck the liquid food into the sampling tube 1. This food quality inspection sampling device is convenient to use. Through the above components, it can simultaneously meet the sampling of liquid and solid food, has a more comprehensive function, and can reduce the number of tools to be carried, facilitating the travel of the staff.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
