Description

Technical Field

[0001] This utility model relates to the field of oil return pipe technology, and in particular to an adjustable rubber-sealed oil return pipe. Background Technology

[0002] The fuel return line is an inconspicuous part on a car engine, but it plays an important role in ensuring the normal operation of the engine. Most cars now have a fuel return line. After the fuel pump supplies fuel to the engine and creates a certain pressure, in addition to supplying fuel to the fuel injectors, the excess fuel is sent back to the fuel tank through the fuel return line. Of course, excess gasoline vapor collected by the carbon canister also returns to the fuel tank through the fuel return line. The fuel return line can return excess fuel to the fuel tank, which can relieve gasoline pressure and reduce fuel consumption.

[0003] Most existing rubber-sealed oil return pipes lack length adjustment functionality during use. This results in the oil return pipe being too long during installation, which can easily cause it to loosen, wobble, and wear on the engine, affecting its service life. Conversely, if the oil return pipe is too short, it cannot be installed and used, thus failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided an adjustable rubber-sealed oil return pipe to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please refer to Figure 1-4An adjustable rubber-sealed oil return pipe includes an adjustment box 1. Screws 2 are rotatably connected to the top and bottom left and right sides of the inner cavity of the adjustment box 1 via bearings. Rectangular plates 3 are threaded onto the outer surfaces of the screws 2. Lifting plates 4 are fixedly connected to opposite sides of the two rectangular plates 3. An arc-shaped extrusion block 5 is fixedly connected to the front position of the top of the lifting plate 4. A rubber-sealed oil return pipe body 6 is disposed in the inner cavity of the adjustment box 1 and above the arc-shaped extrusion block 5. Both ends of the rubber-sealed oil return pipe body 6 extend to the outside of the adjustment box 1. Arc-shaped guides are fixedly connected to the left and right sides of the inner cavity of the adjustment box 1 and above the rubber-sealed oil return pipe body 6. Limiting components 8 are provided on the front of the lifting plate 4 and the block 7. The bottom of the screw 2 passes through the debugging box 1 and is fixedly connected to the rotating handle 10. There are two rotating handles 10. The left and right sides of the back of the inner cavity of the debugging box 1 are fixedly connected to the slide rails 11. The outer surface of the slide rails 11 is slidably connected to the inner surface of the lifting plate 4. The top of the left and right sides of the debugging box 1 is fixedly connected to the mounting plate 12. The mounting plate 12 has mounting holes 13 at the front and back positions of the top. The left and right sides of the debugging box 1 have through holes 14. The inner surface of the through hole 14 is fixedly connected to the buffer pad, and the inner surface of the buffer pad is tightly fitted to the connection of the rubber sealing oil return pipe body 6.

[0033] In this embodiment: By setting up an adjustment box 1, a screw 2, a rectangular plate 3, a lifting plate 4, an arc-shaped extrusion block 5, and an arc-shaped guide block 7, the present invention can conveniently adjust the length of the rubber sealing oil return pipe body 6. By setting up the above structure, it can have the function of length adjustment, thereby meeting the needs of customers.

[0034] Example 2:

[0035] Reference Figure 1 , Figure 2 and Figure 4 The limiting component 8 includes a stud 801. The outer surface of the stud 801 is fixedly connected to the connection of the lifting plate 4. The front of the stud 801 penetrates the debugging box 1 and is threadedly connected to a limiting nut 802. The outer surface of the limiting nut 802 is tightly fitted to the connection of the debugging box 1. The front of the debugging box 1 is provided with a moving groove 9 that works with the stud 801. The stud 801 is located in the inner cavity of the moving groove 9.

[0036] In this embodiment: By setting studs 801 and limiting nuts 802, the present invention can conveniently limit the connection between the lifting plate 4 and the debugging box 1.

[0037] The implementation principle of this utility model is as follows: In use, the operator uses the mounting plate 12, mounting holes 13, and screws to fix the device in a designated position on the engine housing. Then, when it is necessary to shorten the length of the rubber-sealed return oil pipe body 6, the operator simultaneously rotates the handles 10 on both sides, causing the handles 10 to drive the screw 2 to rotate on the inner surface of the rectangular plate 3. This causes the rectangular plates 3 on both sides to move the lifting plate 4 upwards. Simultaneously, the lifting plate 4 moves the arc-shaped guide block 7 upwards, compressing the rubber-sealed return oil pipe body 6, causing it to be compressed and moved upwards. This causes both ends of the rubber-sealed return oil pipe body 6 to retract into the inner cavity of the adjustment box 1. When both ends of the rubber-sealed return oil pipe body 6 are adjusted to the appropriate length, the operator rotates the moving limit nut 802, so that the limit nut 802 rotates and moves on the outer surface of the stud 801 and fits tightly with the connection of the adjustment box 1, thereby limiting the connection between the lifting plate 4 and the adjustment box 1, completing the shortening of the length of the rubber-sealed return oil pipe body 6, thus facilitating the installation of the rubber-sealed return oil pipe body 6 and preventing the rubber-sealed return oil pipe body 6 from being too long, causing it to loosen and sway and wear on the engine.

[0038] When the length of the rubber seal return oil pipe body 6 needs to be extended for adjustment, the operator simultaneously rotates the handles 10 on both sides in opposite directions. This causes the handles 10 to drive the screw 2 to rotate in the opposite direction on the inner surface of the rectangular plate 3. This causes the rectangular plates 3 on both sides to move the lifting plate 4 downwards. Simultaneously, the lifting plate 4 moves the arc-shaped guide block 7 downwards away from the rubber seal return oil pipe body 6, thus relieving the pressure on the rubber seal return oil pipe body 6. Then, the operator simultaneously pulls both ends of the rubber seal return oil pipe body 6, causing it to stretch and move out of the adjustment box 1, thus achieving the extension adjustment of the rubber seal return oil pipe body 6. The length of the return oil pipe body 6 is extended. Then, the operator rotates the moving limit nut 802, so that the limit nut 802 rotates and moves on the outer surface of the stud 801 and fits tightly with the connection of the debugging box 1, thereby limiting the connection between the lifting plate 4 and the debugging box 1, completing the extension of the length of the rubber-sealed return oil pipe body 6. This facilitates the installation of the rubber-sealed return oil pipe body 6 and avoids the rubber-sealed return oil pipe body 6 being too short, which would prevent the rubber-sealed return oil pipe body 6 from being unable to be installed. The device is simple to operate and easy to adjust the length, thus meeting the needs of customers.
