The utility model has the characteristics of simple structure, easy to manufacture and good sealing performance by setting a series of structures.

[0004] This device inserts the sampling tube into the surface of the tank storing lubricating oil. Since the sampling tube is arranged on the inner wall of the sampling tube, even when the sampling tube is inserted into the tank surface, the sampling tube still needs to rub against the tank surface. The loss of the sampling tube increases after long - term use. When pushing the sampling tube into the tank, since the length of the sampling tube is a fixed length, if the liquid level in the storage tank is lower than the sampling tube, sampling cannot be carried out, and sampling tubes of different sizes need to be replaced for sampling, which reduces the working efficiency of the staff. Therefore, a sampler for lubricating oil detection is proposed to solve the above problems. Summary of the Utility Model

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0034] Refer to Figure 1 - Figure 3 For an embodiment provided by the present invention: A sampler for lubricating oil detection includes a cylinder body 1, so that the cylinder body 1 provides a fixing effect for the entire device. A fixing mechanism is arranged inside the cylinder body 1, so that the fixing mechanism can provide a stable fixing effect for the tube body 10. The fixing mechanism includes a tube body 10, and the outer wall of the tube body 10 is slidably connected to the inner wall of the cylinder body 1, so that the cylinder body 1 provides a stable sliding effect for the tube body 10. Three circular notches are opened on the outer wall of the tube body 10, so that the tube body 10 can reach different positions under the insertion of the round rod 5 into different circular notches. The inner wall of the cylinder body 1 is elastically connected to a round rod 5 through a spring 11. One end of the spring 11 is fixedly connected to the inner wall of the cylinder body 1, and the other end of the spring 11 is fixedly connected to the outer wall of the round rod 5, so that the spring 11 cooperates with the inner wall of the cylinder body 1 to provide a reaction force for the round rod 5.

[0035] Refer to Figure 1 - Figure 2 、 Figure 4 The outer wall of the round rod 5 is slidably connected to the inner wall of the cylinder body 1, so that the inner wall of the cylinder body 1 provides a stable sliding effect for the round rod 5. The outer wall of the round rod 5 is inserted into the inner wall of the circular notch to provide a fixing effect for the tube body 10. The outer wall of the tube body 10 is fixedly connected to a sampling tube 7, so that the tube body 10 provides a stable fixing effect for the sampling tube 7. A piston 8 is slidably connected to the inner wall of the tube body 10, so that the tube body 10 provides a stable sliding effect for the piston 8. The outer wall of the piston 8 is fixedly connected to a rod body 3, so that the rod body 3 can drive the piston 8 to move back and forth. A sealing rubber ring 9 penetrates through the outer wall of the tube body 10, and the inner wall of the sealing rubber ring 9 is slidably connected to the outer wall of the rod body 3, so that when the rod body 3 slides on the inner wall of the sealing rubber ring 9, the outside air will not enter the tube body 10. The outer wall of the rod body 3 is fixedly connected to a disc 4, so that the staff can pull or push the disc 4 to move the rod body 3 back and forth.

[0036] Reference Figure 2 - Figure 4 On the outer wall of the cylinder body 1, a puncture tube 6 is fixedly connected, so that the cylinder body 1 provides a stable fixing effect for the puncture tube 6. The inner wall of the puncture tube 6 is slidably connected to the outer wall of the sampling tube 7. When the puncture tube 6 pierces the surface of the lubricating oil storage tank to be detected, the sampling tube 7 enters the tank along the inner wall of the puncture tube 6. The outer wall of the sampling tube 7 is slidably connected to the inner wall of the cylinder body 1, so that the cylinder body 1 provides a stable sliding effect for the sampling tube 7. A fixing ring 2 penetrates through the inner wall of the cylinder body 1, so that the cylinder body 1 provides a stable fixing effect for the fixing ring 2. The inner wall of the fixing ring 2 is slidably connected to the outer wall of the rod body 3, so that the fixing ring 2 provides a stable sliding effect for the rod body 3.

[0037] Working principle: After the staff selects the lubricating oil to be sampled, hold the cylinder body 1 and pierce the puncture tube 6 into the surface of the lubricating oil storage tank. At this time, since the diameter of the puncture tube 6 is larger than that of the sampling tube 7, the sampling tube 7 enters the tank along the puncture tube 6 until the surface of the tank fits against the outer wall of the cylinder body 1. Then pull the disc 4, so that the disc 4 drives the rod body 3 to slide along the inner walls of the fixing ring 2 and the sealing rubber ring 9, and the piston 8 moves backward.

[0038] If it is found that no liquid is sucked, the round rod 5 on the surface of the cylinder body 1 can be pulled up, and the disc 4 is pushed towards the tank, so that the piston 8 is pushed to the tube wall of the tube body 10 by the rod body 3 fixedly connected to the disc 4, and the tube body 10 moves towards the tank, so that the sampling tube 7 extends into the interior of the tank and contacts the liquid. At this time, the round rod 5 is released, so that the round rod 5 is inserted into the outermost circular notch among the three circular notches of the tube body 10 under the reaction force generated by the spring 11 cooperating with the inner wall of the cylinder body 1, and the tube body 10 is fixed.

[0039] At this time, pull the disc 4 again, so that the disc 4 drives the rod body 3 to slide along the inner walls of the fixing ring 2 and the sealing rubber ring 9, and the piston 8 moves backward, sucking the lubricating oil into the tube body 10 and sending it to the detection device for detection. Embodiment

[0040] Reference Figures 5-6, on the basis of the above embodiment, this embodiment provides a sampler for lubricating oil detection, including an installation mechanism 12. The installation mechanism 12 is arranged on the puncture tube 6. The installation mechanism 12 includes a ring body 121. The outer wall of the ring body 121 is fixedly connected to the outer wall of the cylinder body 1, so that the cylinder body 1 provides a supporting and fixing effect for the ring body 121. An installation ring 122 is inserted into the inner wall of the ring body 121. The ring body 121 is installed in the inner wall of the installation ring 122 by means of insertion. A wedge block 123 is slidably connected to the inner wall of the installation ring 122. An installation groove is formed on the outer wall of the installation ring 122, and the installation groove is a vertical groove, which is convenient for the staff to insert their fingers into the inner wall of the installation groove to press the wedge block 123. The outer wall of the wedge block 123 is clamped with the inner wall of the installation groove. The ring body 121 and the installation ring 122 are connected and fixed by the cooperation of the wedge block 123 and the installation groove. The outer wall of the wedge block 123 is fixedly connected to one end of the installation spring 124. The other end of the installation spring 124 is fixedly connected to the inner wall of the installation ring 122. The wedge block 123 is driven to move outwards by the force of the installation spring 124, so that the wedge block 123 maintains the clamping and fixing effect with the installation groove. The inner wall of the installation ring 122 is fixedly connected to the outer wall of the puncture tube 6. The design of the installation ring 122 facilitates the installation or disassembly of the puncture tube 6.

[0041] Working principle: Considering that after long-term puncture work through the puncture tube 6, the puncture tube 6 is prone to wear, resulting in deformation and damage of the puncture tube 6, which affects the extraction efficiency of the sampling tube 7 arranged on the inner wall of the puncture tube 6. Then, by pressing the wedge block 123, the wedge block 123 can be moved into the inner wall of the installation ring 122, so that the wedge block 123 releases the clamping and fixing effect on the installation groove. Thus, the installation ring 122 and the puncture tube 6 can be taken outwards, and a new puncture tube 6 can be installed and placed. Therefore, the problem of wasting materials when the whole device needs to be replaced when the puncture tube 6 is deformed after long-term use is avoided.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
