Description

Technical Field

[0001] This utility model belongs to the technical field of engine oil inlet hoses, specifically a quick-connect structure for engine oil inlet hoses. Background Technology

[0002] The engine fuel inlet hose is an important component of the fuel supply system. Its main function is to deliver fuel from the fuel tank to the engine injectors or cylinders, where it mixes with air to form a combustible mixture to support the combustion process.

[0003] In conjunction with the return line, it maintains the pressure balance of the fuel system, ensuring a stable fuel supply to the engine under different operating conditions, while returning excess fuel to the fuel tank through the return line; fuel is pumped from the fuel tank to the injector through the fuel inlet hose and injected into the cylinder or intake manifold to mix with air.

[0004] In current technologies, when installing the oil inlet hose, the compact and complex environment of the engine compartment can cause shaking and high temperatures during the connection process, leading to the oil inlet hose becoming loose. Therefore, a quick-connect structure for the engine oil inlet hose is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a quick-connect structure for engine oil inlet hose.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The quick-connect structure for an engine oil inlet hose of this utility model includes an oil inlet hose body, a connector installed at the end of the oil inlet hose body; a connecting pipe provided at the end of the connector; a clamping sealing plate fixedly connected to the end of the connector; a cavity opened inside the clamping sealing plate; a locking groove opened at the end of the connecting pipe; a locking block slidably connected inside the cavity; a first spring fixedly connected to the end of the locking block, and the other end of the first spring fixedly connected to the inner side wall of the cavity.

[0007] Preferably, a pull rod is fixedly connected to the end of the locking block; and a handle is fixedly connected to the end of the pull rod.

[0008] Preferably, a limiting ring is fixedly connected to the inner wall of the connecting pipe; a guide rod is slidably connected to the end of the limiting ring; a sealing block is fixedly connected to the end of the guide rod; and a compression rod is fixedly connected to the inner wall of the connector.

[0009] Preferably, a limiting plate is fixedly connected to the end of the guide rod; a second spring is fixedly connected to the end of the limiting plate, and the other end of the second spring is fixedly connected to the top of the limiting ring.

[0010] Preferably, a sealing gasket is fixed to the inner wall of the connector; a protective gasket is installed at the end of the locking block; and the end of the locking block is semi-circular.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides a quick-connect structure for an engine oil inlet hose. By inserting the connector into the inside of the connecting pipe, the clamping sealing plate is snapped onto the end of the connecting pipe. During the snapping process, as the connecting pipe moves, the end of the connecting pipe squeezes the locking block, causing the locking block to be compressed and contracted into the cavity, compressing the first spring to generate elastic force. When the locking groove and the cavity are aligned, the first spring generates elastic force to push the locking block into the locking groove for snapping and fixing, thereby quickly snapping and fixing the oil inlet hose body and the connector, improving the stability of the oil inlet hose body and the connector.

[0013] This utility model provides a quick-connect structure for an engine oil inlet hose. When the oil inlet hose body and connector need to be disassembled and repaired, the pull handle is pulled to drive the pull rod to slide upward, so that the pull rod drives the locking block to slide out from the inside of the locking groove and retract into the inside of the cavity. Then, the workers can remove the oil inlet hose body and connector from the end of the connecting pipe for disassembly and repair. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides a quick-connect structure for an engine oil inlet hose, including an oil inlet hose body 1, with a connector 21 installed at one end of the oil inlet hose body 1; a connecting pipe 22 is provided at the end of the connector 21; a clamping sealing plate 23 is fixedly connected to the end of the connector 21; a cavity 25 is formed inside the clamping sealing plate 23; a locking groove 24 is formed at the end of the connecting pipe 22; a locking block 26 is slidably connected inside the cavity 25; a first spring 27 is fixedly connected to the end of the locking block 26, and the other end of the first spring 27 is fixedly connected to the inner wall of the cavity 25; during operation, when the oil inlet hose body 1 and the... When the connector 21 is installed, it is inserted into the inside of the connecting pipe 22, so that the clamping sealing plate 23 is snapped into the end of the connecting pipe 22. During the snapping process, as it moves, the port of the connecting pipe 22 squeezes the locking block 26, so that the locking block 26 is squeezed and shrinks into the cavity 25, squeezing the first spring 27 to generate elastic force. When the locking groove 24 and the cavity 25 are aligned with each other, the first spring 27 generates elastic force to push the locking block 26 into the locking groove 24 for snapping and fixing, so as to quickly snap and fix the oil inlet hose body 1 and the connector 21, improving the stability of the oil inlet hose body 1 and the connector 21.

[0025] Furthermore, such as Figures 3-4 As shown, a pull rod 31 is fixedly connected to the end of the locking block 26; a pull handle 32 is fixedly connected to the end of the pull rod 31. During operation, when it is necessary to disassemble and repair the oil inlet hose body 1 and the connector 21, the pull handle 32 is pulled to drive the pull rod 31 to slide upward, so that the pull rod 31 drives the locking block 26 to slide out from the inside of the locking groove 24 and retract into the inside of the cavity 25. Then, the workers remove the oil inlet hose body 1 and the connector 21 from the end of the connecting pipe 22 for disassembly and repair.

[0026] Furthermore, such as Figures 3-4As shown, a limiting ring 41 is fixedly connected to the inner wall of the connecting pipe 22; a guide rod 42 is slidably connected to the end of the limiting ring 41; a sealing block 43 is fixedly connected to the end of the guide rod 42; and a pressing rod 44 is fixedly connected to the inner wall of the connector 21. During operation, when the connector 21 is inserted into the connecting pipe 22, the connector 21 drives the pressing rod 44 to press against the end of the sealing block 43, causing the sealing block 43 to drive the guide rod 42 to move to the side, thereby opening the limiting ring 41. This allows the oil inside the connector 21 to flow quickly through the gap created by the separation between the sealing block 43 and the limiting ring 41, further improving the sealing effect.

[0027] Furthermore, such as Figures 3-4 As shown, a limiting plate 51 is fixedly connected to the end of the guide rod 42; a second spring 52 is fixedly connected to the end of the limiting plate 51, and the other end of the second spring 52 is fixedly connected to the top of the limiting ring 41; during operation, when the guide rod 42 slides, it pulls the limiting plate 51 to slide to the bottom and squeezes the second spring 52 to generate elastic force, so that the limiting plate 51 plays a limiting role, and then the second spring 52 plays a buffering and resetting role.

[0028] Furthermore, such as Figures 3-4 As shown, a sealing gasket 33 is fixedly attached to the inner wall of the connector 21; during operation, the sealing gasket 33 is installed on the inner wall of the connector 21 to snap onto the end of the connector 21, thereby achieving a sealing effect.

[0029] Furthermore, such as Figures 3-4 As shown, a protective pad is installed at the end of the locking block 26; the end of the locking block 26 is semi-arc-shaped; during operation, by installing a protective pad at the end of the locking block 26, the locking block 26 can play a protective role during the locking process.

[0030] Working principle: When installing the oil inlet hose body 1 and connector 21, the connector 21 is inserted into the connecting pipe 22, causing the clamping sealing plate 23 to engage with the end of the connecting pipe 22. During the engagement process, as the pipe moves, the end of the connecting pipe 22 presses against the locking block 26, causing the locking block 26 to contract into the cavity 25, compressing the first spring 27 and generating elastic force. When the locking groove 24 and the cavity 25 are aligned, the first spring 27 generates elastic force to push the locking block 26 into the locking groove 24 for engagement and fixation, thus quickly engaging and fixing the oil inlet hose body 1 and connector 21, improving the stability of the oil inlet hose body 1 and connector 21. When disassembling and repairing the oil inlet hose body 1 and connector 21 are required, pulling the handle 32 drives the pull rod 31 to slide upwards, causing the pull rod 31 to slide the locking block 26 out of the locking groove 24 and contract into the cavity 25. Then, the operator can disassemble the oil inlet hose body 1 and connector 21. The pipe body 1 and connector 21 are removed from the end of the connecting pipe 22 for disassembly and maintenance. When connector 21 is inserted into the connecting pipe 22, it causes the connector 21 to drive the extrusion rod 44 to press against the end of the sealing block 43. This causes the sealing block 43 to drive the guide rod 42 to move to the side, opening the limiting ring 41. This allows the oil inside connector 21 to flow quickly through the gap between the sealing block 43 and the limiting ring 41, further improving the sealing effect. When the guide rod 42 slides, it pulls the limiting plate 51 to slide to the bottom, compressing the second spring 52 to generate elastic force. This allows the limiting plate 51 to have a limiting effect, while the second spring 52 has a buffering and resetting effect. A sealing gasket 33 is installed on the inner wall of connector 21 to lock onto the end of connector 21, thus achieving a sealing effect. A protective gasket is installed at the end of locking block 26 to improve the protection effect of locking block 26 during the locking process.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
