Description

Technical Field

[0001] This invention relates to the technical field of oil filler plugs, specifically to an oil filler plug with a convenient sealing effect. Background Technology

[0002] Gasoline, an important petroleum product, is a transparent or semi-transparent, volatile, and flammable mixture of hydrocarbons obtained through the refining of light petroleum fractions. It can be used as fuel and appears as a transparent liquid. Gasoline is primarily used in internal combustion engines for transportation, especially as a power source for vehicles such as automobiles, motorcycles, small aircraft, lawnmowers, and chainsaws. During combustion, gasoline mixes with air and is ignited by a spark plug in the engine's combustion chamber, burning rapidly and releasing a large amount of heat energy, which is converted into mechanical energy to propel the vehicle or equipment forward. Gasoline also has wide applications in the chemical and pharmaceutical industries. Due to its volatility, gasoline requires a fuel filler plug to seal the inlet after being injected into the fuel tank. However, if a suitable fuel filler plug is lost, the tank cannot be sealed. Since different fuel tanks have different inlet sizes, a universal fuel filler plug cannot be used for sealing. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an oil filler plug with a convenient sealing effect, which has the advantages of being able to seal oil filler ports of different sizes. This solves the problem that different oil tank inlets have different sizes, making it impossible to use a universal oil filler plug for sealing.

[0004] To achieve the aforementioned purpose of sealing oil inlets of different sizes, this invention provides the following technical solution: an oil inlet plug with convenient sealing effect, comprising a fixed post, two vertical tubes fixedly passing through the fixed post, an annular groove on the fixed post, an annular airbag fixedly installed in the annular groove, the annular airbag being fixedly connected to the two vertical tubes, a horizontal groove on the fixed post, a fixed strip movably connected in the horizontal groove, a connecting ring fixedly installed on the fixed strip, the connecting ring being movably sleeved on the fixed post, sliding grooves on both sides of the fixed strip, a screw rod disposed in the two sliding grooves, the screw rod movably passing through the fixed strip, the threads on the left and right sides of the screw rod being arranged oppositely, a slider movably connected in both sliding grooves, both sliders being threadedly sleeved on the screw rod, a fixed block fixedly installed on the lower side of both sliders, and a flexible plate fixedly installed on the side of the two fixed blocks that are close to each other.

[0005] Preferably, two rotating rings are fixedly sleeved on the screw, and the outer side walls of the two rotating rings are provided with several circular grooves.

[0006] Preferably, a number of rubber strips are fixedly installed on the outer side walls of both rotating rings, and each rubber strip has an anti-slip groove.

[0007] Preferably, the two inner walls of the two slides are provided with limiting grooves, and each of the four limiting grooves is movably connected to a limiting block, and the four limiting blocks are respectively fixedly connected to the two sliders.

[0008] Preferably, a square box is fixedly connected to the upper end of the two vertical pipes, and an air pump pipe is fixedly connected to the square box. A one-way valve is provided on the air pump pipe.

[0009] Preferably, each of the four limiting grooves is provided with a baffle, which facilitates fixed connection with the left and right sides of the fixing strip.

[0010] Compared with the prior art, this invention provides an oil filler plug with convenient sealing effect, which has the following advantages: 1. This convenient sealing oil plug works by inserting the fixed post into the oil filling port, and then injecting air into the annular airbag through two vertical tubes. This causes the annular airbag to expand and fit against the inner wall of the oil filling port. Then, a rotating screw is added, which drives two sliders to move closer to each other. This causes two fixed blocks to move closer to each other, and the two flexible plates can then press against the outer wall of the oil filling port, thus fixing the fixed post and sealing oil filling ports of different sizes.

[0011] 2. This oil filler plug with convenient sealing effect allows users to easily rotate the two rotating rings back and forth through several round grooves and rubber strips. The stability of the slider can be improved through two limiting blocks and limiting grooves. At the same time, the baffle can prevent the slider from disengaging from the limiting blocks and limiting grooves. Gas can be injected into the two vertical pipes simultaneously through the air pipe and square box. Attached Figure Description

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

[0016] Please see Figures 1-4 This invention provides a technical solution: an oil filler plug with convenient sealing effect, comprising a fixed post 1, two vertical tubes 9 fixedly passing through the fixed post 1, an annular groove 8 on the fixed post 1, an annular airbag 7 fixedly installed in the annular groove 8, the annular airbag 7 being fixedly connected to the two vertical tubes 9, a horizontal groove 6 on the fixed post 1, a fixed strip 3 movably connected in the horizontal groove 6, a connecting ring 2 fixedly installed on the fixed strip 3, the connecting ring 2 being movably sleeved on the fixed post 1, sliding grooves 13 on both the left and right sides of the fixed strip 3, a screw 5 disposed in the two sliding grooves 13, the screw 5 movably passing through the fixed strip 3, the threads on the left and right sides of the screw 5 being arranged in opposite directions, and a slider 14 movably connected in both sliding grooves 13. Both sliders 14 are threaded onto the screw 5. A fixing block 16 is fixedly installed on the lower side of each slider 14. A flexible plate 15 is fixedly installed on the side of each fixing block 16 that is close to each other. By inserting the fixing post 1 into the oil inlet, air can be injected into the annular airbag 7 through the two vertical pipes 9.

This causes the two fixing blocks 16 to move closer to each other. The two flexible plates 15 can then be used to press against the outer wall of the oil inlet, thus fixing the fixing post 1 and sealing oil inlets of different sizes. Two rotating rings 4 are fixedly sleeved on the screw 5. Several circular grooves 19 are formed on the outer walls of both rotating rings 4. Several rubber strips 18 are fixedly installed on the outer walls of both rotating rings 4. Each rubber strip 18 has an anti-slip groove 17. Limiting grooves 20 are formed on the front and rear inner walls of the two sliding grooves 13. Limiting blocks 22 are movably connected within each of the four limiting grooves 20. The four limiting blocks 22 are fixedly connected to two sliders 14 respectively. A square box 10 is fixedly connected to the upper end of the two vertical tubes 9. An air pump pipe 12 is fixedly connected to the square box 10. A one-way valve 11 is provided on the air pump pipe 12, and baffles 21 are provided at each of the four limit grooves 20. The four baffles 21 facilitate the fixed connection with the left and right sides of the fixing strip 3. The two rotating rings 4 can be rotated back and forth by the user through several circular grooves 19 and rubber strips 18. The stability of the slider 14 can be improved by the two limit blocks 22 and the limit grooves 20. At the same time, the baffles 21 can prevent the slider 14 from separating from the limit blocks 22 from the slide grooves 13 and the limit grooves 20. Gas can be injected into the two vertical pipes 9 simultaneously through the air pump pipe 12 and the square box 10.

[0017] in: Fixed post 1: Made of plastic; Connecting ring 2: Used to connect and fix the strip 3; Fixed bar 3: can move up and down within the transverse groove 6; Rotating ring 4: can rotate, and simultaneously drives screw 5 to rotate; Screw 5: The threads on the left and right sides of screw 5 are set in opposite directions. When screw 5 rotates, it can drive the two sliders 14 to move closer to each other or to move the two sliders 14 further away from each other. Horizontal groove 6: Used to connect and fix the strip 3; 7-ring airbag: can expand and seal the oil inlet; Annular groove 8: Used for installing annular airbag 7; Vertical tube 9: can inject air into the annular airbag 7; Box 10: can inject air into the two vertical tubes 9; One-way valve 11: can prevent air leakage into the injection box 10; Air inflator 12: Allows air to be injected into the square box 10; Slide 13: Used to connect the courtesan 14; Slider 14: can move back and forth within the slide groove 13; Flexible board 15: can improve the fixing effect of fixing block 16; Fixing block 16: The device can be fixed by squeezing and clamping the outer wall of the oil injection port; Anti-slip groove 17: can be used with rubber strip 18 to facilitate the user to rotate the rotating ring 4 back and forth; Rubber strip 18: allows users to easily rotate the rotating ring 4; Circular groove 19: Users can help rotate the rotating ring 4 by inserting a round rod-shaped tool into the circular groove 19; Limiting groove 20: used to connect limiting block 22; Baffle 21: can block limit block 22; Limiting block 22: works with limiting groove 20 to improve the stability of slider 14; In use, the first step is to insert the fixing post 1 into the oil inlet, and then inject air into the annular airbag 7 through the two vertical pipes 9. This will cause the annular airbag 7 to expand and fit against the inner wall of the oil inlet. Then, the rotating screw 5 will drive the two sliders 14 to move closer to each other. This will drive the two fixing blocks 16 to move closer to each other. The two flexible plates 15 will then press against the outer wall of the oil inlet, thus fixing the fixing post 1 and sealing oil inlets of different sizes.

[0018] Step 2: Several circular grooves 19 and rubber strips 18 allow users to easily rotate the two rotating rings 4 back and forth. Two limiting blocks 22 and limiting grooves 20 can improve the stability of the slider 14. At the same time, the baffle 21 can prevent the slider 14 from separating from the limiting blocks 22 from the sliding grooves 13 and limiting grooves 20. Gas can be injected into the two vertical pipes 9 simultaneously through the air pipe 12 and the square box 10.
