[0002] Lubricant preparation liquid usually refers to a solvent or base liquid used to prepare lubricants. In the fields of industry and manufacturing, lubricants are usually complex chemical formulas containing multiple ingredients, such as grease, additives and solvents. The function of lubricant preparation liquid is mainly to prepare and dilute the original ingredients of lubricants. At the same time, the formula of lubricant preparation liquid needs to be changed according to the specific lubricant type and application requirements. Therefore, it needs to be sampled and tested. The existing sampling and testing equipment can basically meet daily use needs, but there are still some shortcomings that need to be improved.

When the one-way shaft gear 20 on the rotating shaft rotates on the rack 24, under the action of centrifugal force, the slider 30 slides along the L-shaped hole 29, and under the action of the compression spring, the cylinder drives the one-way shaft gear 20 thereon to engage with another rack 24, so that the docking tube 22 is docked with the branch pipe 13 and the sampling tube 2, and the switching of the pipeline is realized, thereby reducing the possibility of mutual interference between samples and improving the sampling accuracy of the device. The limiting hole 8 is "L"-shaped, and through cooperation with the moving plate 10, the cylinder can be quickly reset, avoiding the one-way shaft gear 20 hindering the conversion tube 25 from docking with the branch pipe 13, and improving the overall flexibility of the device.

[0055] One end of the conversion tube 25 is in a truncated cone shape, which can improve the tightness of the conversion tube 25 and the branch tube 13 after splicing, thereby improving the sealing of the device. Through the cooperation between the extrusion sleeve 34 and the return spring 36, the two semicircular plates 33 can change the inner diameter of the extrusion tube 35 on the conversion tube 25, thereby reducing the overflow of residual materials when the conversion tube 25 rotates, reducing the subsequent cleaning work of the device, and improving the operation efficiency of the device.

[0056] The material removal component includes two piston rods 12 respectively arranged on the butt joint 22 and the discharge pipe 9 . The two piston rods 12 are jointly provided with a pressure plate 4 . The pressure plate 4 is provided with two sliding grooves 17 .

[0057] A retracting piston 28 is provided on the piston rod 12 on the butt tube 22.

[0058] A card slot is provided on the shell 1, a chuck 16 matching the card slot is provided on the shell 1, a recovery tank 15 is provided on the chuck 16, a recovery tube is provided on the recovery tank 15, a contraction groove is provided at one end of the recovery tube and the sampling tube 2, and a splicing component is provided on the contraction groove.

[0059] The splicing component comprises a splicing tube slidably arranged in the contraction groove, a push plate 37 is fixedly mounted on the splicing tube, and two electric push rods 38 are arranged on both sides of the push plate 37.

[0060] Through the cooperation between the card slot and the chuck 16, the recovery tank 15 can be quickly disassembled, which is convenient for quick cleaning of the recovery tank 15. At the same time, the electric push rods 38 on the sampling tube 2 are respectively located on the corresponding slideways 23, and the electric push rods 38 on the recovery tube are located in the shell 1. Through the setting of the electric push rods 38, the conversion tube 25 can be quickly docked, thereby improving the flexibility of the device.

[0061] In the present invention, a lubricant configuration liquid detection sampling device has the following specific operating steps:

[0062] When sampling, install the sampling bottle 5 on the cover plate, and then fix the recovery tank 15 on the shell 1 through the chuck 16, then connect the external pipeline with the sampling tube 2, and put the external pipeline into the lubricating liquid configuration tank, and then manually pull the pull rod 3 to drive the diaphragm 18 to expand and contract through the pull rod 3, thereby changing the internal space size of the discharge tube 9, causing the internal air to shrink, and the lubricating liquid configuration liquid enters the conversion tube 25 from the external pipeline through the sampling tube 2, and then enters the discharge tube 9 through one of the branches 13, and finally enters the sampling bottle 5 from the discharge tube 9. After entering the sampling bottle 5, under the action of gravity, the weighing spring 6 begins to stretch, and the weight is recorded when the elastic potential energy is balanced with the gravitational potential energy.

[0063] When cleaning the pipeline, after taking the sample, gently lift and push the pressure plate 4, so that the spring rod 11 drives the movable plate 10 to move in the limiting hole 8, and the movable plate 10 drives the conversion tube 25 to move between the slide plate 1 21 and the slide plate 2 26 through the rotating shaft, so that the conversion tube 25 is separated from the branch pipe 13. When the movable plate 10 moves to the farthest point of the limiting hole 8, under the action of gravity, the conversion tube 25 drives the sampling tube 2 to move down along the slide groove, and at the same time, the spring rod 11 is stretched by the movable plate 10. After falling a distance, the one-way shaft gear 20 on the rotating shaft is meshed with one of the racks 24. At the same time, the electric push rod 38 on the sampling tube 2 pulls the push plate 37 to separate the splicing tube from the conversion tube 25, and the extrusion sleeve 34 is reset under the action of the reset spring 36. The two semicircular plates 33 squeeze the extrusion tube 35, so that the conversion tube 25 is completely closed to prevent residual materials from overflowing. Then the one-way shaft gear 20 drives the conversion tube 25 to rotate through the rotating shaft. At the same time, the slider 30 drives the cylinder to slide along the L-shaped hole 29 under the action of centrifugal force, slides to the corner, and pushes the cylinder to extend under the action of the compression spring, so that the one-way shaft gear 20 on the cylinder is engaged with the other rack 24. At the same time, the conversion tube 25 rotates to the docking tube 22, and the electric push rod 38 on the recovery tube pushes the push plate 37, so that the push plate 37 squeezes the reset spring 36 through the extrusion sleeve 34, so that the semicircular plate 33 moves to the groove of the extrusion sleeve 34, thereby restoring the extrusion tube 35 and docking the recovery tube with the conversion tube 25.

[0064] When cleaning the sampling tube 2, the rotating shaft drives the magnetic ring rod 19 to move on the sampling tube 2 through the rotating disk 27, and drives the scraper ring 32 to move in the sampling tube 2 through magnetic force, thereby quickly cleaning the material inside the sampling tube 2 and reducing interference between samples.

[0065] When cleaning the conversion tube 25 and the discharge tube 9, the pressing plate 4 is pressed, and the pressing plate 4 pushes the two piston rods 12 to move, and the conversion tube 25 and the discharge tube 9 are cleaned, and the residual materials enter the recovery tank 15 and the sampling bottle 5 respectively.

[0066] When switching pipelines, pull the pressure plate 4 to make the piston rod 12 move upward to the docking tube 22. At this time, the elastic potential energy of the spring rod 11 is equal to the gravitational potential energy of the conversion tube 25 and its structure. Continue to pull the pressure plate 4, and the spring rod 11 pulls the conversion tube 25 upward through the moving plate 10, and the one-way shaft gear 20 on the cylinder drives the conversion tube 25 to rotate under the action of another rack 24. When the conversion tube 25 is parallel to the branch tube 13, the electric push rod 38 on the sampling tube 2 pushes the push plate 37 to dock the telescopic tube with the conversion tube 25, and then the moving plate 10 is moved to make the moving plate 10 push the slider 30 to reset, and finally push the pressure plate 4 backward to dock the conversion tube 25 with the branch tube 13.

[0067] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
