DETAILED DESCRIPTION
[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0026] like Figure 1~Figure 5 As shown, the present embodiment proposes an oil mark outer cover body 1, the oil mark outer cover body 1 is provided with a first through hole 2, four second through holes 3 are provided at the top of the oil mark outer cover body 1, the first through hole 2 is located between the four second through holes 3, a rubber ring 6 is provided at the bottom of the oil mark outer cover body 1, the first through hole 2 is located inside the rubber ring 6, an insert block 9 is provided on the top of the rubber ring 6, the rubber ring 6 is fixedly connected to the insert block 9, a slot 8 is provided at the bottom end of the oil mark outer cover body 1, the insert block 9 is located inside the slot 8, a matching scale 11 is provided on the front of the oil mark outer cover body 1, a circular groove is provided on the oil mark outer cover body 1, and a calibration bubble 12 is provided inside the circular groove of the oil mark outer cover body 1.
[0027] In this embodiment, the material of the oil mark outer cover body 1 is set to nylon material to improve the overall toughness. At the same time, the oil mark outer cover body 1, the first through hole 2, the second through hole 3, the third through hole 4 and the slot 8 are all processed and formed by an injection mold at one time, with high dimensional accuracy and longer service life. At the same time, a rubber ring 6 is set to seal the gap at the connection between the oil mark outer cover body 1 and the pump body oil mark to improve the sealing performance and prevent oil from flowing out through the gap. The plug block 9 is inserted into the slot 8, so that the oil mark outer cover body 1 and the rubber ring 6 are locked with each other, thereby achieving a sealing effect, reducing the entry of debris in the air, and causing the debris in the engine oil to gradually increase, so as to avoid damage to the vacuum pump outer cover. Example
[0028] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fixed block 14 is provided inside the second through hole 3, a sliding rod 13 is fixedly connected to the top of the fixed block 14, a fourth through hole 19 is opened inside the fixed block 14, a moving block 15 is provided inside the fourth through hole 19, the moving block 15 is rotatably connected inside the fourth through hole 19, a special-shaped block 16 is fixedly connected to the right side of the moving block 15, a lifting rod 17 is meshingly connected to the right side of the special-shaped block 16, and the lifting rod 17 slides inside the fixed block 14, so as to better connect the oil mark outer cover body 1 with the oil tank for easy fixation.
[0029] In this embodiment, by inserting the fixing block 14 into the interior of the second through hole 3, when installing the oil mark outer cover body 1, it is only necessary to sleeve the oil mark outer cover body 1 on the outer side of the slide rod 13, and then slide into the interior of the second through hole 3 along the outer side of the slide rod 13. At this time, the moving block 15 is squeezed, and the moving block 15 and the right side drive the special-shaped block 16 to engage with the lifting rod 17. At this time, the lifting rod 17 rises inside the fixing block 14, and then the fixing block 14 can be slid into the interior of the second through hole 3 more conveniently. Example
[0030] like Figure 1~Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, the present embodiment further proposes that a spacer block 18 is fixedly connected to the outer side of the moving block 15, and the spacer block 18 is tightly arranged against the fourth through hole 19. The sliding rod 13, the fixed block 14, the moving block 15, the special-shaped block 16, the lifting rod 17, the spacer block 18, and the fourth through hole 19 are arranged into four groups and are respectively fixed inside the second through hole 3. The oil mark outer cover body 1 has third through holes 4 on both sides of the body, and the third through holes 4 are connected to the slots 8. The third through holes 4 are provided with threads inside, and the third through holes 4 are spirally connected with threaded rods 7 inside. The outer side of the threaded rod 7 is fixedly connected with a handle 5. The oil mark outer cover body 1 has a thread groove 10 inside, and the threaded rod 7 is rotatably connected to the thread groove 10. Two calibration bubbles 12 are provided, the front of the calibration bubble 12 is in a vertical direction, and the other calibration bubble 12 is installed horizontally in two horizontal directions. The threaded rod 7 is provided on the opposite side of the handle 5, and the opposite end of the threaded rod 7 is fixedly connected to the two handles 5 respectively.
[0031] In this embodiment, the threaded rod 7 is inserted into the third through hole 4, and then the handle 5 is rotated. The handle 5 drives the threaded rod 7 to rotate and extend into the thread groove 10, so that the threaded rod 7 is locked with the insert block 9, thereby limiting the vertical movement of the rubber ring 6, thereby improving the firmness between the oil mark outer cover body 1 and the rubber ring 6. Similarly, reversing the handle 5 allows the threaded rod 7 to move out of the thread groove 10, thereby releasing the lock between the oil mark outer cover body 1 and the rubber ring 6, and at the same time facilitating the installation and removal of the rubber ring 6, and facilitating the inspection and replacement of the rubber ring 6.
[0032] Working principle of the utility model
[0033] In the utility model, by setting a rubber ring 6, the gap at the connection between the oil mark outer cover body 1 and the pump body oil mark is sealed to improve the sealing performance and prevent the oil from flowing out through the gap. The plug block 9 is inserted into the slot 8, so that the oil mark outer cover body 1 and the rubber ring 6 are locked. At the same time, the threaded rod 7 is inserted into the third through hole 4, and then the handle 5 is rotated. The handle 5 drives the threaded rod 7 to rotate and extend into the thread groove 10, so that the threaded rod 7 and the plug block 9 are locked, thereby limiting the vertical movement of the rubber ring 6, improving the firmness between the oil mark outer cover body 1 and the rubber ring 6. Similarly, the handle 5 is reversed to make the threaded rod 7 move out of the thread groove 10, thereby releasing the lock between the oil mark outer cover body 1 and the rubber ring 6.
[0034] Next, the fixing block 14 is inserted into the interior of the second through hole 3. Therefore, when installing the oil mark outer cover body 1, it is only necessary to sleeve the oil mark outer cover body 1 on the outer side of the slide rod 13, and then slide it into the interior of the second through hole 3 along the outer side of the slide rod 13. At this time, the moving block 15 is squeezed, and the moving block 15 and the right side drive the special-shaped block 16 to engage with the lifting rod 17. At this time, the lifting rod 17 rises inside the fixing block 14, and then it is more convenient to slide the fixing block 14 into the interior of the second through hole 3. Through the scale 11 set on the outside of the oil mark outer cover body 1, the scale 11 can be used to more intuitively observe the oil amount in the oil tank to prevent the vacuum pump from overflowing, leaking or drying up due to too much or too little oil in the oil tank. The oil tank is calibrated by two calibration bubbles 12 to see if it is level, to prevent the oil tank from being unstable due to uneven placement, which may easily mislead the staff's judgment on the oil amount.
[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
