Description

Technical Field

[0001] This utility model relates to the field of lubricating oil sampling technology, specifically to a lubricating oil sampling and testing device. Background Technology

[0002] Lubricating oil is commonly found in daily life. It is used between two objects to reduce friction when they come into contact. It has a variety of uses, including auxiliary cooling, cleaning, and rust prevention. During mass production, manufacturers will sample and test lubricating oil to determine its quality and distinguish between different types of products. Therefore, lubricating oil sampling and testing equipment is needed.

[0003] Currently, some lubricating oil sampling and testing equipment on the market includes, for example, a utility model patent with authorization announcement number CN215296816U that discloses a lubricating oil testing sampling device. This device involves placing a suction tube located below a shield and a sleeve at the lower end into a container of lubricating oil. Pulling the push rod upwards causes the piston, which is fixedly connected to it, to rise within the sleeve, allowing lubricating oil to enter the sleeve through the suction tube at the lower end. Simultaneously, the shield on the upper side seals the container opening, preventing external debris from entering and contaminating the lubricating oil during sample extraction. However, this device relies on the sleeve, push rod, and suction tube to generate negative pressure for liquid extraction, and the length cannot be adjusted as needed. Therefore, it cannot sample lubricating oil at different depths within the container, resulting in low accuracy of sample analysis.

[0004] Therefore, we propose a lubricating oil sampling and testing device to solve the problems mentioned above. Utility Model Content

[0010] Furthermore, the telescopic sampling tube includes a fixed tube and multiple telescopic tubes. The fixed tube is connected to the bottom of the sampling cylinder. One of the telescopic tubes is sleeved with the fixed tube, and each telescopic tube is sleeved inside the previous telescopic tube.

A first compression spring is provided between the fixed tube and every two adjacent limit rings. A connecting ring connected to a first pull line is provided on the telescopic tube at the end.

A pull ring connected to the second pull line is provided on the outer side of the ring body, and a plurality of evenly distributed locking slots are provided on the sampling cylinder, the locking slots being adapted to the locking blocks.

[0012] Furthermore, a thread guide ring is provided on the surface of the sampling cylinder near the bottom, and the thread guide ring has a thread guide hole adapted to the first pull wire.

[0013] Furthermore, the telescopic tube at the end is connected to two branch tubes, one end of each branch tube is connected to a one-way liquid transfer device, and the liquid transfer directions of the two one-way liquid transfer devices are opposite.

[0014] Furthermore, two semi-circular dustproof plates and two first hinge blocks are symmetrically arranged on the cylinder. Each semi-circular dustproof plate is provided with an adaptation groove that matches the cylinder.

[0025] Embodiments of this utility model:

[0026] like Figures 1-6As shown, this utility model provides a lubricating oil sampling and testing device, including a sampling cylinder 1, a winding reel 3, and a rotation control ring 5. A telescopic sampling tube 2 is provided at the bottom of the sampling cylinder 1. The sampling cylinder 1 includes a cylinder body 101, and a push-pull rod 102 is provided inside the cylinder body 101. A piston head 103 is provided at one end of the push-pull rod 102. The telescopic sampling tube 2 includes a fixed tube 21 and multiple telescopic tubes 22. The fixed tube 21 is connected to the bottom of the sampling cylinder 1. One of the telescopic tubes 22 is sleeved with the fixed tube 21, and each telescopic tube 22 is sleeved inside the previous telescopic tube 22. The diameters of the multiple telescopic tubes 22 decrease sequentially. A limit ring 23 is provided at one end of each telescopic tube 22. A first compression spring 24 is provided between the fixed tube 21 and every two adjacent limit rings 23. A connecting ring 6 connected to a first pull line 4 is provided on the telescopic tube 22 at the end. With this arrangement, when not in use, the telescopic sampling tube 2 can be retracted below the sampling cylinder 1 for easy carrying.

[0027] like Figures 1-6 As shown, the winding reel 3 is mounted on the sampling tube, and a first pull wire 4 is connected between the winding reel 3 and the tail end of the telescopic sampling tube 2. A wire guide ring 7 is provided near the bottom of the sampling tube 1, and the wire guide ring 7 has a wire guide hole adapted to the first pull wire 4. A rotation control ring 5 is located on the top of the winding reel 3. The winding reel 3 rotates by the rotation control ring 5 to wind up the first pull wire 4. The rotation control ring 5 includes a ring body 51 connected to the winding reel 3. A spring compression chamber 511 is provided inside the ring body 51. A baffle 52 and a second compression spring 53 are provided inside the spring compression chamber 511. A locking block 54 is connected to the side of the baffle 52, and a second pull line 55 is connected to the other side of the baffle 52. A pull ring 56 connected to the second pull line 55 is provided on the outer side of the ring body 51. Multiple evenly distributed slots 1011 are provided on the sampling cylinder 1. The slots 1011 are adapted to the locking block 54. One side of the locking block 54 is set with an arc-shaped structure. With this setting, after the rotation control ring 5 is rotated, the rotation control ring 5 can be limited and fixed by the cooperation of the slots 1011 and the locking block 54. Setting one side of the locking block 54 with an arc-shaped structure can facilitate the rotation operation.

[0028] like Figure 3 and Figure 5As shown, the telescopic tube 22 at the end is connected to two branch tubes 8. One end of each branch tube 8 is connected to a one-way liquid filter 9. The liquid flow directions of the two one-way liquid filters 9 are opposite. The one-way liquid filter 9 includes a liquid flow tube 91, a liquid flow chamber 901 is opened in the liquid flow tube 91, and liquid flow holes 902 are opened at both ends of the liquid flow tube 91. A third compression spring 92 and a baffle ball 93 are installed in the liquid flow chamber 901. A T-shaped liquid flow groove 931 is opened on the baffle ball 93. The diameter of the baffle ball 93 is larger than the diameter of the liquid flow hole 902 and smaller than the inner diameter of the liquid flow chamber 901. The baffle balls 93 of the two one-way filters face opposite directions. By setting the one-way liquid filter 9, the lubricating oil can be prevented from entering in advance during the sampling operation, which would affect the sampling accuracy. The two one-way liquid filters 9 can extract and export lubricating oil samples respectively with the cooperation of the sampling cylinder 1.

[0029] like Figures 1-2 As shown, two semi-circular dustproof plates 10 and two first hinge blocks 11 are symmetrically arranged on the cylinder 101. Each semi-circular dustproof plate 10 has an adaptation groove that matches the cylinder 101. The lower surface of the semi-circular dustproof plate is connected to a second hinge block 12. The first hinge block 11 and the second hinge block 12 are hinged together. With this arrangement, when performing sampling, the two semi-circular dustproof plates 10 can be opened and aligned to form a complete circle. Then, they can be placed on the opening of the lubricating oil barrel to prevent external debris from entering the barrel and contaminating the lubricating oil during the sampling process.

[0030] Specifically, firstly, pulling the pull ring 56 pulls the locking block 54 out of the slot 1011 via the second pull line 55, releasing the fixation of the rotation control ring 5. The rotation control ring 5 then drives the winding reel 3 to rotate, unwinding the first pull line 4. Next, the telescopic sampling tube 2 is extended under the action of the first compression spring 24. Once the appropriate length is reached, the pull ring 56 is released, and the locking block 54, under the action of the second compression spring 53, inserts into the slot 1011, fixing the rotation control ring 5 and thus fixing the length of the telescopic sampling tube 2. Then, the two semi-circular dustproof plates are opened. Align the components 10 to form a complete circle. After inserting the telescopic sampling tube 2 into the lubricating oil tank, the semi-circular dustproof plate 10 will cover the opening of the lubricating oil tank for dust prevention. Then, pull the push-pull rod 102 to control the piston head 103 to move, generating negative pressure in the cylinder 101. The lubricating oil will push open the baffle ball 93 of one of the one-way liquid transfer devices 9 and enter the cylinder 101 through the branch pipe 8 and the telescopic sampling tube 2 to complete the sampling. When it is necessary to export the lubricating oil sample, simply push the push-pull rod 102 to control the piston head 103 to move. The lubricating oil will push open the baffle ball 93 of the other one-way liquid transfer device 9 and then export the sample.
