[0002] With the rapid development of my country's national economy and the improvement of equipment management level, the quality requirements of lubricating oil, the "blood" of equipment that ensures its reliable operation, are becoming higher and higher. In the process of lubricating oil production, it is necessary to effectively sample the lubricating oil and conduct various tests to meet the sales standards before it can be officially filled and sold. Therefore, quality inspection of lubricating oil is a very important step. It can ensure the quality of lubricating oil and prevent too many problems from occurring in actual use later, which will affect the rights and interests of consumers.

[0003] When a traditional lubricating oil sampler takes a sample from the bottom of a sample barrel, the lower end of the entire device needs to be extended into the bottom of the lubricating oil sample barrel. When taking samples, this type of sampler may bring a large amount of impurities adhering to the outer wall of the sampler into the oil tank, affecting the detection results of the lubricating oil sample, and may also cause the lubricating oil in the sample barrel to deteriorate. In addition, after sampling, a large amount of lubricating oil will be stained on the outer wall of the sampler, and the oil stains on the outer wall need to be cleaned manually, which is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figures 1 to 3 As shown, the technical solution adopted in this specific implementation is:

[0022] A lubricating oil sample barrel bottom sampler, comprising a sampler body 1, a sampling hose 2 detachably arranged on the sampler body 1, a counterweight device detachably arranged on the sampling hose 2 and away from one end of the sampler body 1, a quick-release device is arranged between the sampler body 1 and the sampling hose 2, the quick-release device comprising a tubular connecting end 3 arranged at one end of the sampler body 1, a connecting groove 4 provided on the connecting end 3 for inserting one end of the sampling hose 2, a plurality of sliding holes 5 evenly provided on the side wall of the connecting end 3 and connected to the connecting groove 4, a resisting clamping piece 6 which can be radially slidably arranged in each of the sliding holes 5 and is used to resist the outer wall of the sampling hose 2 to limit the sampling hose 2 from axially sliding along the connecting end 3 and disengaging from the connecting end 3, and a locking device provided on the connecting end 3 and used to releasably lock the resisting clamping piece 6.

[0023] The locking device includes a locking ring 7 which is sleeved on the connecting end 3 and can slide in the axial direction of the connecting end 3, a butting boss 8 which is arranged on the inner wall of the locking ring 7 and the inner wall of which abuts against the butting clamp 6 so that the butting clamp 6 keeps abutting against the side wall of the sampling hose 2, a limiting member 9 which is arranged on the connecting end 3 and located on one side of the locking ring 7 and is used to abut against the side wall of the butting boss 8 to prevent the locking ring 7 from detaching from the connecting end 3 when sliding on the connecting end 3, and an elastic member which is arranged between the connecting end 3 and the locking ring 7 and is located on the side of the locking ring 7 away from the limiting member 9 and is used to keep the butting boss 8 abutting against the movement trend of the limiting member 9.

[0024] The elastic member is a compression spring 10 which is sleeved on the connecting terminal 3 and has two ends respectively abutting against the connecting terminal 3 and the abutting boss 8. The limiting member 9 is a limiting retaining ring arranged on the connecting terminal 3. The limiting retaining ring abuts against the abutting boss 8 away from the side of the compression spring 10. The outer wall of the connecting terminal 3 is provided with a slot for the limiting retaining ring to be inserted into.

[0025] At least one sealing ring 11 is disposed between the connection end 3 and the sampling hose 2 to prevent lubricating oil from leaking from between the connection end 3 and the sampling hose 2 .

[0026] The abutting engaging member 6 is a ball, and the inner wall spacing of the connecting groove 4 is smaller than the diameter of the ball, thereby preventing the ball from escaping from the connecting end 3 through the connecting groove 4. In addition, in the present embodiment, the inner wall opening diameter of the abutting boss 8 gradually increases from the side close to the compression spring 10 to the side close to the limit retaining ring, so that when the locking ring 7 slides along the axial direction of the connecting end 3 and compresses the compression spring 10, the ball can slide outward along the sliding hole 5 for a certain distance, so that the ball no longer abuts against and restricts the sampling hose 2, so that the staff can disassemble and assemble the sampling hose 2.

[0027] The sampler body 1 includes a cylindrical shell 101, a sealing cover 102 arranged on the shell through a threaded connection, a sealing head 103 slidably arranged in the shell (a sealing ring is arranged between the side wall of the sealing head 103 and the inner wall of the shell), and a pull rod 104 with one end connected to the sealing head 103 and the other end passing through the sealing cover 102. The connecting terminal 3 is arranged at the end of the shell away from the sealing cover 102 and is connected to the inside of the shell.

[0028] The balancing weight device includes a connecting sleeve 12 (a metal connecting sleeve 12 in the present embodiment) which is arranged on the end of the sampling hose 2 away from the connecting end 3, and a balancing weight ball 13 which is detachably arranged on the connecting sleeve 12 (in the present embodiment, the balancing weight ball 13 is a metal balancing weight ball 13, which will sink when placed in lubricating oil, and the specific metal and size are not described here), the connecting sleeve 12 is provided with an external thread, the balancing weight ball 13 is connected to the connecting sleeve 12 by a thread, and the balancing weight ball 13 is provided with an oil inlet connected to the sampling hose 2.

[0029] The sampling hose 2 is provided with scale lines 14. In the present embodiment, the sampling hose 2 is a transparent plastic sampling hose 2, so that the sampling amount can be observed and controlled through the scale lines 14. Specifically, by pulling the pull rod 104 by the staff, the sealing head 103 can be driven to slide in the shell, and the interior of the shell is connected with the sampling hose 2, so that the lubricating oil can be sucked through the sampling hose 2 and the counterweight ball 13 to achieve sampling.

[0030] The working principle of this utility model:

[0031] When sampling: the staff only needs to extend the sampling hose 2 and the counterweight ball 13 into the sample barrel. Under the action of gravity, the end of the sampling hose 2 with the counterweight ball 13 sinks to the bottom of the barrel. At this time, the staff pulls the pull rod 104 to drive the sealing head 103 in the shell to slide toward one end of the sealing cover 102. At this time, the lubricating oil can be sucked through the oil inlet of the sampling hose 2 and the counterweight ball 13 to realize the sampling operation.

[0032] After the sampling test is completed, when the sampling hose 2 needs to be replaced or cleaned, the staff can control the locking ring 7 to slide along the axial direction of the connecting end 3 to compress the compression spring 10. At this time, the ball is no longer restricted and can slide outward along the sliding hole 5 for a certain distance, and no longer abuts against the outer wall of the sampling hose 2 to restrict it. At this time, the staff can pull the sampling hose 2 out of the connecting groove 4, thereby realizing the disassembly of the sampling hose 2. Similarly, when connecting the sampling hose 2, the staff can control the locking ring 7 to slide along the axial direction of the connecting end 3. Slide to compress the compression spring 10. At this time, the ball slides outward along the sliding hole 5 for a certain distance. Then the staff inserts one end of the sampling hose 2 into the connecting groove 4 and loosens the locking ring 7. The locking ring 7 is reset under the action of the compression spring 10. At this time, the inner wall opening diameter of the abutting boss 8 gradually increases from the side close to the compression spring 10 to the side close to the limit retaining ring, forming an inclined compression surface, which abuts and pushes the ball, so that the ball abuts and presses the side wall of the sampling hose 2, thereby realizing the connection and installation.
