[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] With reference to Figures 1-5 The utility model provides an embodiment:

[0028] A kind of sampling equipment convenient to operate, including support frame 1 and fixed ring 5, adjusting mechanism 2 is provided in fixed ring 5 inside, adjusting mechanism 2 includes first sampling cylinder 203, second sampling cylinder 206 and third sampling cylinder 207, piston 204 is slidably arranged in the inside of first sampling cylinder 203, second sampling cylinder 206 and third sampling cylinder 207, multiple pistons 204 upper end are all fixedly arranged with first connecting rod 202, multiple pistons 204 lower end are all fixedly arranged with second connecting rod 205;

[0029] Multiple second connecting rod 205 outer lower end is respectively screw-connected in the inside of multiple first connecting rod 202 upper end, first sampling cylinder 203 and third sampling cylinder 207 opposite end and second sampling cylinder 206 upper and lower ends are all set with sliding slot 208, multiple sliding slot 208 inside are all slidably arranged with sliding block 209, two upper ends of multiple sliding block 209 are all fixedly arranged with first positioning rod 210, two lower ends of multiple sliding block 209 are all rotatably arranged with second positioning rod 211, multiple first positioning rod 210 outer part is respectively screw-connected in multiple second positioning rod 211 inside, one upper end of multiple first connecting rod 202 is screw-connected with connecting disc 201, lifting plate 4 upper end is set in connecting disc 201 lower end;

[0030] Specifically, after the fixing ring 5 is adjusted to the appropriate working position, the electric telescopic rod 3 starts to work. The output end of the electric telescopic rod 3 pushes the lifting plate 4 upward. The upper end of the lifting plate 4 is tightly connected to the lower end of the connecting plate 201, and the connecting plate 201 is fixed to the first connecting rod 202 by a threaded connection. Therefore, the upward movement of the lifting plate 4 will drive the first connecting rod 202 to move upward synchronously. Since the lower end of the first connecting rod 202 is fixedly connected to the piston 204, the piston 204 will slide upward inside the first sampling cylinder 203, the second sampling cylinder 206, and the third sampling cylinder 207, causing the air inside the sampling cylinder to be gradually discharged. A negative pressure environment is created, under which food samples are automatically drawn into the sampling tube through the opening at the bottom of the tube, thus completing the sampling operation efficiently and accurately. Furthermore, the first sampling tube 203, the second sampling tube 206, and the third sampling tube 207 are all equipped with scale lines on the outside. By controlling the extension distance of the electric telescopic rod 3, quantitative extraction can be achieved. This not only makes the operation simple but also effectively reduces the contamination and damage to the samples, ensuring the originality and integrity of the samples. In addition, the first sampling tube 203, the second sampling tube 206, and the third sampling tube 207 are all fixedly equipped with sealing rings to effectively prevent sample leakage during the sampling process and ensure the accuracy of the sampling results.

[0031] In addition, to meet diverse sampling needs, the device also features adjustable sampling tube spacing. Since the lower outer end of the second connecting rod 205 is threaded to the upper inner end of the first connecting rod 202, operators can flexibly adjust the length and spacing between the sampling tubes by rotating the second connecting rod 205. After adjusting to a suitable spacing, the first positioning rod 210 and the second positioning rod 211 are adjusted accordingly, and then the slider 209 is inserted into the groove 208, forming a reliable limiting structure. This effectively prevents the second sampling tube 206 and the third sampling tube 207 from moving with the piston 204 during sampling, ensuring stable relative positions between the sampling tubes and further improving sampling accuracy and reliability. This adjustable sampling tube spacing design allows the device to adapt to sampling needs at different heights and positions, enhancing its versatility and practicality. It provides a more flexible and efficient solution for food quality testing. Furthermore, sampling tubes can be added or removed as needed, enabling modular operation.

[0032] Reference Figures 1-4 An electric telescopic rod 3 is fixedly installed on one side inside the fixed ring 5. A lifting plate 4 is fixedly installed at the output end of the electric telescopic rod 3. A limit ball 11 is slidably installed at the upper end inside the fixed ring 5. A motor 7 is fixedly installed at the upper end of one side of the support frame 1. A lead screw 8 is fixedly installed at the output end of the motor 7.

[0033] Fixing blocks 12 are fixedly installed on both sides of the first sampling cylinder 203 and the third sampling cylinder 207. Among the multiple fixing blocks 12, the two outer sides near the lifting plate 4 are both set inside the fixing ring 5. The lower ends of the two limiting balls 11 are respectively set on the upper ends of the multiple fixing blocks 12 near the lifting plate 4. Two springs 10 are fixedly installed on the upper end of the inner side of the fixing ring 5. The lower ends of the two springs 10 are respectively fixed on the upper ends of the limiting balls 11. The screw 8 is threadedly connected to the moving column 6. The upper end of the moving column 6 is slidably set on the upper end of the inner side of the moving column 6. The upper end of the guide rod 9 is slidably set on the upper end of the support frame 1. The lower end of the moving column 6 is fixedly set on one side of the upper end of the fixing ring 5.

[0034] Specifically, when installing and fixing the sampling cylinder, the first sampling cylinder 203 is inserted into the fixing ring 5 and then rotated. During the rotation, the fixing block 12 on the outside of the first sampling cylinder 203 will exert a squeezing effect on the limiting ball 11. When the first sampling cylinder 203 is precisely rotated to the preset position, the spring 10, which was originally in a compressed state, quickly rebounds due to its own elastic potential energy, pushing the limiting ball 11 to reset. At this time, the lower end of the limiting ball 11 is precisely embedded in the upper end of the fixing block 12, forming a stable locking structure, thereby achieving reliable limiting and fixing of the first sampling cylinder 203. This effectively avoids the phenomenon of shaking or displacement of the sampling cylinder during the sampling process, providing a solid guarantee for the accuracy of the sampling operation, ensuring that the sampled can truly reflect the overall condition of the food, and providing a reliable basis for subsequent testing and analysis.

[0035] During sampling, the operator first moves the entire sampling equipment to a suitable sampling position, then fixes the support frame 1 in the appropriate position. Subsequently, the motor 7 at the upper end of the support frame 1 is started. The output end of the motor 7 drives the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the moving column 6, the moving column 6 will move along the axis of the lead screw 8 under the rotation drive of the lead screw 8. At the same time, the guide rod 9 plays a limiting and guiding role, ensuring that the moving column 6 can move smoothly and accurately along the predetermined direction. The guide rod 9 also has scale lines on the outside, making it easy to see the position of the moving column 6. The movement of the moving column 6 drives the fixing ring 5 to move downward synchronously, thereby realizing the adjustment of the sampling tube position. This allows the sampling tube to easily adapt to the sampling needs of samples at different heights and positions, improving the versatility and practicality of the equipment and reducing sampling errors caused by limited sampling positions.

[0036] Working principle: When the sampling tube is installed inside the fixing ring 5, the first sampling tube 203 is first sleeved inside the fixing ring 5, and then rotated so that the fixing block 12 on the outside of it presses the limiting ball 11. When the first sampling tube 203 rotates to the set position, the spring 10 rebounds and pushes the limiting ball 11 to reset, so that the lower end of the limiting ball 11 is embedded in the upper end of the fixing block 12, thereby realizing the limiting and fixing of the sampling tube, which can prevent the sampling tube from shaking or shifting during the sampling process and ensure the accuracy of the sampling.

[0037] When in use, first move the entire device to a suitable position, then start the motor 7 at the upper end of the support frame 1, so that its output end drives the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the moving column 6, under the rotation of the lead screw 8, the moving column 6 will move along the lead screw 8 under the limiting action of the guide rod 9, thereby driving the fixed ring 5 to move downward, thus realizing the adjustment of the sampling cylinder position.

[0038] When the fixed ring 5 is adjusted to the appropriate position, the electric telescopic rod 3 starts to move. Its output end pushes the lifting plate 4 to move upward. The upper end of the lifting plate 4 is connected to the lower end of the connecting plate 201. The connecting plate 201 is threadedly connected to the first connecting rod 202. Therefore, the upward movement of the lifting plate 4 will drive the first connecting rod 202 to move upward. The lower end of the first connecting rod 202 is fixedly connected to the piston 204. So the piston 204 will slide upward inside the first sampling cylinder 203, the second sampling cylinder 206 and the third sampling cylinder 207, so that a negative pressure is formed inside the sampling cylinder, thereby sucking the food sample into the cylinder through the opening at the lower end of the sampling cylinder, and completing the sampling operation.

[0039] Furthermore, the spacing between the sampling cylinders can be adjusted according to actual sampling requirements. Since the lower outer end of the second connecting rod 205 is threaded to the upper inner end of the first connecting rod 202, the length and spacing between the sampling cylinders can be adjusted by rotation. After the adjustment is completed, the first positioning rod 210 and the second positioning rod 211 are adjusted. Then, the slider 209 is inserted into the slide groove 208 to restrict and prevent the second sampling cylinder 206 and the third sampling cylinder 207 from moving with the piston 204.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
