Technical Field

[0001] This utility model relates to the field of edible vegetable oil sampling technology, and in particular to a stratified sampling device. Background Technology

[0002] Edible vegetable oils are oils extracted from the seeds, fruits, germs, and other parts of plants and are consumed by humans. They are important cooking ingredients and sources of nutrition in daily life. Their main component is triglycerides, and they also contain small amounts of vitamins, phospholipids, phytosterols, and other nutrients. Sampling devices are required when testing edible vegetable oils.

[0003] Existing sampling devices are inconvenient to adjust the height of the sampling tube according to actual testing needs, making it difficult to extract edible vegetable oil from storage tanks in layers and affecting the convenience of actual sampling and testing. Utility Model Content

[0004] The purpose of this invention is to provide a layered sampling device to solve the problem that existing sampling devices cannot easily adjust the height of the sampling tube according to actual testing needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a layered sampling device, including a U-shaped positioning frame;

[0006] An adjustment mechanism is fixedly connected to the outer wall of the U-shaped positioning frame;

[0007] The adjustment mechanism includes a sleeve fixedly installed on the outer wall of the U-shaped positioning frame. A frame plate is fixedly connected to the inner wall of the sleeve. A rotating shaft is movably connected inside the frame plate. A conveying roller is fixedly connected to the outer wall of the rotating shaft. A threaded hole is opened inside the sleeve. A positioning bolt is movably connected inside the threaded hole. A sampling tube is movably connected to the outer wall of the conveying roller.

[0008] Preferably, the frame plate has an open design, and the frame plate forms a rotating structure with the conveyor roller through a rotating shaft, which can make the conveyor roller rotate along the frame plate.

[0009] Preferably, the sleeve is threadedly connected to the positioning bolt through a threaded hole, and the conveying roller is in contact with the outer wall of the sampling tube, so that the positioning bolt can rotate and squeeze and limit the sampling tube.

[0010] Preferably, the U-shaped positioning frame has a threaded groove inside and a guide groove inside. An installation mechanism is movably connected inside the threaded groove. The installation mechanism includes a threaded post movably installed inside the threaded groove. A knob is fixedly connected to one end of the threaded post, and a receiving plate is movably connected to the other end of the threaded post. A through hole is opened inside the receiving plate. A guide plate is fixedly connected to one side of the receiving plate. A limit rod is movably connected inside the receiving plate. A clamping plate is fixedly connected to the outer wall of the limit rod, and a return spring is installed on one side of the clamping plate.

[0011] Preferably, the U-shaped positioning frame is threadedly connected to the threaded column via a threaded groove, and the U-shaped positioning frame forms a sliding structure with the guide plate via a guide groove, which allows the threaded column to rotate and move along the threaded groove.

[0012] Preferably, the threaded post forms a rotating structure with the receiving plate through a through hole, and the receiving plate has an open design, which allows the end of the threaded post to rotate along the through hole.

[0013] Preferably, the receiving plate and the limiting rod form a sliding structure, and the return spring is sleeved and installed on the outer wall of the limiting rod, so that the limiting rod can slide along the receiving plate.

[0014] The advantages of the stratified sampling device provided by this utility model are as follows:

[0015] By using the set adjustment mechanism and sampling tube, the sampling tube is passed through the sleeve and attached to the outer wall of the conveying roller. The sampling tube can be raised and lowered according to the actual required sampling depth. When the sampling tube is adjusted to the required sampling position, the positioning bolt is rotated so that the end of the positioning bolt can squeeze the sampling tube and limit the sampling tube. This makes it easy to adjust the sampling depth of the sampling tube according to the actual layered sampling requirements.

[0016] Furthermore, the rotating shaft can make the conveying rollers rotate along the frame, further improving the smoothness of lifting and adjusting the sampling tube.

[0017] By rotating the threaded column, one end of the threaded column can be rotated along the through hole, which will move the receiving plate and cause multiple limit rods to come into contact with the mouth of the edible vegetable oil storage tank. This makes it easier to install the U-shaped positioning frame at the mouth of the storage tank and further facilitates the sampling operation of edible vegetable oil.

[0018] Furthermore, the combined effect of the guide plate and the guide groove can improve the stability of the receiving plate movement;

[0019] Furthermore, since the limiting rod and the receiving plate form a sliding structure, under the action of the return spring, the limiting rod at different positions can be adaptively slid and adjusted according to the shape difference of the can opening. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides a layered sampling device, including a U-shaped positioning frame 1.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an adjustment mechanism 2 is fixedly connected to the outer wall of the U-shaped positioning frame 1;

[0029] The adjusting mechanism 2 includes a sleeve 21 fixedly installed on the outer wall of the U-shaped positioning frame 1. A frame plate 22 is fixedly connected to the inner wall of the sleeve 21. A rotating shaft 23 is movably connected inside the frame plate 22. A conveying roller 24 is fixedly connected to the outer wall of the rotating shaft 23. A threaded hole 25 is opened inside the sleeve 21. A positioning bolt 26 is movably connected inside the threaded hole 25. A sampling tube 3 is movably connected to the outer wall of the conveying roller 24. The frame plate 22 is designed with an open hole. The frame plate 22 and the conveying roller 24 form a rotating structure through the rotating shaft 23. The sleeve 21 is threadedly connected to the positioning bolt 26 through the threaded hole 25. The conveying roller 24 is in contact with the outer wall of the sampling tube 3.

[0030] By placing the U-shaped positioning frame 1 at the mouth of the edible vegetable oil storage tank, and then passing the sampling tube 3 through the sleeve 21 and attaching it to the outer wall of the conveying roller 24, the sampling tube 3 can be adjusted up and down according to the actual required sampling depth. Under the action of the rotating shaft 23, the conveying roller 24 can be rotated along the frame plate 22. When the sampling tube 3 is adjusted to the required sampling position, the positioning bolt 26 is rotated. Since the positioning bolt 26 is threadedly connected to the sleeve 21 through the threaded hole 25, the end of the positioning bolt 26 can squeeze the sampling tube 3, limiting the sampling tube 3, and connecting the output end of the sampling tube 3 to the pump body, thereby enabling stratified sampling of edible vegetable oil.

[0031] Reference Figure 1 , Figure 2 and Figure 5 As shown, the U-shaped positioning frame 1 has a threaded groove 4 inside and a guide groove 5 inside. A mounting mechanism 6 is movably connected inside the threaded groove 4. The mounting mechanism 6 includes a threaded post 61 movably installed inside the threaded groove 4. One end of the threaded post 61 is fixedly connected to a knob 62, and the other end is movably connected to a receiving plate 63. The receiving plate 63 has a through hole 64 inside, and a guide plate 65 is fixedly connected to one side of the receiving plate 63. The receiving plate 63 is movably connected to... A limit rod 66 is connected to the outer wall of the limit rod 66, and a clamping plate 67 is fixedly connected to the outer wall of the clamping plate 67. A return spring 68 is installed on one side of the clamping plate 67. The U-shaped positioning frame 1 is threadedly connected to the threaded post 61 through the threaded groove 4. The U-shaped positioning frame 1 forms a sliding structure with the guide plate 65 through the guide groove 5. The threaded post 61 forms a rotating structure with the receiving plate 63 through the through hole 64. The receiving plate 63 is designed with an open hole. The receiving plate 63 and the limit rod 66 form a sliding structure. The return spring 68 is sleeved and installed on the outer wall of the limit rod 66.

[0032] By rotating the threaded column 61, which is threadedly connected to the U-shaped positioning frame 1 through the threaded groove 4, one end of the threaded column 61 can rotate along the through hole 64, causing the receiving plate 63 to move and the guide plate 65 to slide along the guide groove 5. This causes multiple limiting rods 66 to come into contact with the opening of the edible vegetable oil storage tank. As the receiving plate 63 continues to move, the limiting rods 66 can slide along the receiving plate 63, causing the clamping plate 67 to press against the return spring 68. This allows the limiting rods 66 to press and limit the openings of tanks of different shapes, thus installing the U-shaped positioning frame 1 at the opening of the storage tank.

[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
