Description

Technical Field

[0001] This utility model relates to the field of refueling hoses, specifically to a high-efficiency composite refueling hose for automotive fuel tanks. Background Technology

[0002] The car fuel tank is the container for storing fuel in a car. It is the only place to store fuel in a car that uses gasoline as fuel, and it is also the power source for the engine. The car fuel tank is located inside the car body, and the refueling hose is connected to the fuel tank to transfer fuel from the filler neck to the fuel tank.

[0003] The existing refueling hoses still have the following problems when in use: the existing fuel tank hoses do not have their own installation components, and the connection between the hose and the fuel tank is mostly achieved by clamps. This requires the use of external tools to install and remove the clamps when installing the hose, and the installation and use of the hose is relatively inconvenient.

[0004] Therefore, it is necessary to invent a high-efficiency composite refueling hose for automotive fuel tanks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency composite refueling hose for automotive fuel tanks, in order to solve the problem mentioned in the background art that the existing fuel tank hoses do not have their own installation components, and the connection between the hose and the fuel tank is mostly achieved by clamps. This requires the use of external tools to install and remove the clamps when installing the hose, and the installation and use of the hose is relatively inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automotive fuel tank composite refueling hose, including a fuel tank, an inlet pipe inside the fuel tank, and the inlet pipe and the refueling pipe are connected by an installation assembly. A sealing ring 1 is fixedly installed at the inlet pipe, and a sealing groove is reserved inside the sealing ring 1. The sealing groove matches a sealing ring 2 installed at the end of the refueling pipe. The installation assembly is equipped with an anti-loss component to prevent the installation assembly from detaching from the refueling pipe.

[0007] Preferably, the refueling pipe consists of an integral flexible hose and a PVC rigid pipe fixedly installed at the end of the flexible hose, and the PVC rigid pipe is installed opposite to the oil inlet pipe, and a sealing ring is installed at the end of the PVC rigid pipe.

[0008] Preferably, the mounting assembly includes a threaded groove one pre-set on the outer wall of the oil inlet pipe and a threaded groove two set on the outer wall of the PVC rigid pipe, and both the threaded groove one and the threaded groove two are threadedly connected to the threaded mounting sleeve to ensure a firm connection between the refueling pipe and the oil inlet pipe.

[0009] Preferably, the inner ring of the threaded mounting cylinder is provided with a thread, and the thread is threadedly connected to thread groove one and thread groove two. Furthermore, the inside of the threaded mounting cylinder is provided with an anti-loss component to prevent the refueling pipe from detaching. The threaded connection is relatively tight, ensuring a firm connection between the refueling pipe and the oil inlet pipe.

[0010] Preferably, the anti-loss component includes an annular groove pre-set inside the threaded mounting cylinder, and an annular block is rotatably connected inside the annular groove. The square block fixedly connected to the inner wall of the annular block slides in cooperation with the strip groove reserved inside the PVC rigid pipe, so that the rotation of the threaded mounting cylinder is unobstructed.

[0011] Preferably, there are two blocks, and the two blocks are symmetrically arranged with reference to the central axis of the annular block. The outer wall of the block is attached to the inner wall of the strip groove to achieve a sliding connection. Both ends of the strip groove are closed, so that when the block moves and abuts against the end of the strip groove, there is no room for movement. At this time, the threaded installation cylinder always maintains a threaded connection with the refueling pipe, preventing the threaded installation cylinder from falling off.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This invention aligns the inner sealing groove of a sealing ring 1 fixedly installed at the end of the oil inlet pipe with a second sealing ring, thus connecting the oil inlet pipe and the refueling pipe. Then, by rotating the threaded mounting cylinder, the threaded mounting cylinder, which is threaded to the second threaded groove, shifts during rotation and achieves a threaded connection with the threaded groove 1 on the outer ring of the oil inlet pipe, thereby connecting the oil inlet pipe and the refueling pipe. At this point, the installation of the refueling pipe is relatively convenient and quick, and there is no need to use clamps or external tools, making the installation fast and efficient.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model provides, for example Figure 1-4 The high-efficiency automotive fuel tank composite refueling hose shown includes a fuel tank 1, an inlet pipe 2 inside the fuel tank 1, and a refueling pipe 3 connected by an installation component 7. A sealing ring 4 is fixedly installed at the inlet pipe 2, and a sealing groove 6 is reserved inside the sealing ring 4. The sealing groove 6 matches the sealing ring 5 installed at the end of the refueling pipe 3. The installation component 7 is equipped with an anti-loss component 8 to prevent the installation component 7 from detaching from the refueling pipe 3.

[0023] When in use, the sealing groove 6 inside the sealing ring 4 fixedly installed at the end of the oil inlet pipe 2 is aligned with the sealing ring 5 to connect the oil inlet pipe 2 and the refueling pipe 3. Then, the threaded mounting cylinder 703 is rotated. The threaded mounting cylinder 703, which is threaded to the threaded groove 702, is displaced during rotation and is threaded to the threaded groove 701 on the outer ring of the oil inlet pipe 2, thereby connecting the oil inlet pipe 2 and the refueling pipe 3. At this time, the refueling pipe 3 has its own installation structure, making the installation of the refueling hose more convenient and quick.

[0024] The refueling pipe 3 consists of an integral flexible hose and a PVC rigid pipe fixedly installed at the end of the flexible hose. The PVC rigid pipe is installed opposite to the inlet of the oil inlet pipe 2, and a sealing ring 2 5 is installed at the end of the PVC rigid pipe. The sealing groove 6 inside the sealing ring 1 4 fixedly installed at the end of the oil inlet pipe 2 is opposite to the sealing ring 2 5, so as to achieve a sealed connection between the oil inlet pipe 2 and the refueling pipe 3.

[0025] The mounting component 7 includes a threaded groove 701 pre-installed on the outer wall of the oil inlet pipe 2 and a threaded groove 702 installed on the outer wall of the PVC rigid pipe. Both the threaded groove 701 and the threaded groove 702 are threadedly connected to the threaded mounting cylinder 703, ensuring a firm connection between the refueling pipe 3 and the oil inlet pipe 2. The inner ring of the threaded mounting cylinder 703 is threaded, and the thread is threadedly connected to the threaded groove 701 and the threaded groove 702. Furthermore, the threaded mounting cylinder 703 is equipped with an anti-loss component 8 to prevent detachment from the refueling pipe 3. The threaded connection is relatively tight, ensuring a firm connection between the refueling pipe 3 and the oil inlet pipe 2.

[0026] By rotating the threaded mounting cylinder 703, the threaded mounting cylinder 703, which is threaded to the second threaded groove 702, is displaced during rotation and achieves threaded connection with the first threaded groove 701 on the outer ring of the oil inlet pipe 2, thereby realizing the connection between the oil inlet pipe 2 and the refueling pipe 3. At this time, the installation of the refueling pipe 3 is more convenient and quick.

[0027] The anti-loss component 8 includes an annular groove 801 pre-installed inside the threaded mounting cylinder 703. An annular block 802 is rotatably connected inside the annular groove 801. A square block 803 fixedly connected to the inner wall of the annular block 802 slides in conjunction with a pre-reserved strip groove 804 inside the PVC rigid pipe. This allows the threaded mounting cylinder 703 to rotate without obstruction. Two square blocks 803 are provided, and the two square blocks 803 are symmetrically arranged with reference to the central axis of the annular block 802. The outer wall of the square block 803 is attached to the inner wall of the strip groove 804 to achieve a sliding connection. Both ends of the strip groove 804 are closed, so when the square block 803 moves and abuts against the end of the strip groove 804, there is no room for movement. At this time, the threaded mounting cylinder 703 always maintains a threaded connection with the refueling pipe 3, preventing the threaded mounting cylinder 703 from falling off.

[0028] When the threaded mounting cylinder 703 rotates, the square block 803 is confined inside the strip groove 804, but the annular block 802, which is fixedly connected to the square block 803, is rotatably connected to the annular groove 801 reserved inside the threaded mounting cylinder 703. At this point, the rotation of the threaded mounting cylinder 703 is unaffected. Subsequently, the threaded mounting cylinder 703, which is threadedly connected to the second threaded groove 702, shifts during rotation and achieves a threaded connection with the first threaded groove 701 on the outer ring of the oil inlet pipe 2. When the threaded mounting cylinder 703 shifts, the annular groove 801 rotatably connects to the ring groove 804. The shaped block 802 drives the square block 803 to move synchronously. The square block 803 moves inside the strip groove 804. Both ends of the strip groove 804 are closed, so when the square block 803 moves and abuts against the end of the strip groove 804, there is no room for movement. At this time, the threaded mounting sleeve 703 always maintains a threaded connection with the refueling pipe 3, preventing the threaded mounting sleeve 703 from falling off. This does not affect the connection between the oil inlet pipe 2 and the refueling pipe 3. Moreover, the refueling pipe 3 has its own installation structure, making the installation and connection between the refueling pipe 3 and the oil tank 1 more efficient and convenient.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
