Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to a quick-disassembly engine pipe connector. Background Technology

[0002] In modern industry and transportation, engines, as core power units, are widely used in industries such as automobiles, ships, and aerospace. The internal piping of an engine system is intricate, encompassing key systems such as fuel delivery, coolant circulation, and lubricant transmission. Engine pipe joints, as the hubs connecting these pipes, directly affect the stable operation and service life of the engine.

[0003] However, traditional engine pipe fittings require multiple tools such as wrenches and screwdrivers to tighten and seal in a confined space, which is not only difficult to operate, but also prone to improper installation due to inconvenience, leading to fuel and coolant leaks, affecting engine performance and vehicle safety. At the same time, the disassembly process is cumbersome during maintenance, requiring maintenance personnel to spend a lot of time removing surrounding components before they can disassemble the engine pipe fitting, significantly increasing maintenance time and costs. Therefore, we have introduced a quick-disassembly engine pipe fitting. Utility Model Content

[0004] The main objective of this invention is to provide a quick-disassembly engine pipe connector, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-detachable engine pipe connector includes a connector body, an installation component and a rubber sealing ring fixedly sleeved on the outer surface of the connector body, a locking component movably sleeved on the right end of the connector body, the rubber sealing ring being located between the installation component and the locking component, a connecting pipe fixedly sleeved inside the locking component, a flange fixedly sleeved on the right end of the connecting pipe, and several through fixing holes on the right edge of the flange.

[0007] Preferably, the locking assembly includes a second mounting ring, an outer sleeve fixedly connected to the right end of the second mounting ring, and an inner sleeve fixedly connected to the right inner wall of the outer sleeve.

[0008] Semicircular fitting blocks are fixedly connected to the upper part of the surface and the lower part of the outer surface. A storage hole is opened on the left side of the outer surface of each of the two semicircular fitting blocks. A stabilizing rod is fixedly connected to the inner wall of each of the two storage holes. A fitting head is movably sleeved at the end of each of the two stabilizing rods away from the center of the second mounting ring. A spring is fixedly connected to the end of each of the two fitting heads near the center of the second mounting ring. The ends of the two springs near the center of the second mounting ring are respectively fixedly connected to the inner wall of the corresponding two storage holes.

[0009] By adopting the above technical solution, the locking component and the mounting component can be separated or engaged by pressing the fitting head, without the need for tools such as wrenches and screwdrivers, which greatly shortens the time for installing and disassembling engine pipelines.

[0010] Preferably, the second mounting ring and the outer sleeve are both movably sleeved on the connector body, and the inner sleeve is movably sleeved inside the connector body.

[0011] By adopting the above technical solutions, a tight sealing system is constructed to effectively prevent leakage of media such as fuel and coolant, ensuring the safe and stable operation of the engine system.

[0012] Preferably, the size of the two fitting heads is adapted to the size of the two corresponding storage holes, the two fitting heads are movably sleeved in the two corresponding storage holes, and the outer surface of the two fitting heads is in contact with the inner wall surface of the two corresponding storage holes.

[0013] By adopting the above technical solution, the size of the fitting head is adapted to the size of the storage hole, so that the fitting head maintains a stable movement trajectory when it moves in the storage hole, effectively preventing deviation or shaking.

[0014] Preferably, the two stabilizing rods are located inside the corresponding two springs and have gaps with the inner walls of the corresponding two springs.

[0015] By adopting the above technical solution: the stabilizing rod is located inside the spring, which provides guidance for the extension and retraction of the fitting head and prevents the fitting head from radially shifting or getting stuck in the receiving hole.

[0016] Preferably, the mounting assembly includes a first mounting ring, with semi-circular leaflets fixedly connected to both the upper and lower parts of the outer surface of the first mounting ring. A semi-circular fitting groove is formed at the right end of each of the two semi-circular leaflets, and a U-shaped pressing groove is formed on the outer surface of each of the two semi-circular leaflets. A fitting hole, which passes through the corresponding two U-shaped pressing grooves, is formed on the inner wall of each of the two semi-circular fitting grooves. The first mounting ring is fixedly sleeved on the connector body.

[0017] By adopting the above technical solution, the U-shaped pressing groove facilitates the application of finger force to press the locking head.

[0018] Preferably, the left portions of the two semi-circular fitting blocks are respectively fitted into the corresponding two semi-circular fitting grooves, and the two fitting heads are respectively fitted into the corresponding two fitting holes and extend into the corresponding two U-shaped pressing grooves.

[0019] By adopting the above technical solution, the semi-circular interlocking block and the semi-circular interlocking groove are interlocked to form a locking structure, ensuring that the connection is stable and does not loosen.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. During installation, place the second mounting ring and outer sleeve over the outside of the connector body, and insert the inner sleeve into the inside of the connector body. Press the two fitting heads with your fingers to overcome the spring force and retract them into the storage hole. Keep the fitting heads in the retracted state. Move the locking assembly with the connecting pipe and flange to the left along the connector body. When the semi-circular fitting block reaches the semi-circular fitting groove, release your fingers. The spring will push the fitting head into the fitting hole and extend into the U-shaped pressing groove to complete the locking. During disassembly, place your fingers into the corresponding two U-shaped pressing grooves and press the fitting head to retract it into the storage hole. Keep the fitting head in the retracted state. Move the locking assembly along with the connecting pipe and flange to the right along the connector body until the semi-circular fitting block disengages from the semi-circular fitting groove. No complicated tools are required, and one person can quickly complete the operation, greatly improving the efficiency of engine maintenance and repair.

[0022] 2. The rubber sealing ring is located between the first mounting ring and the second mounting ring. When the locking component and the mounting component are engaged and locked, the rubber sealing ring is squeezed and deformed, filling the gap between the first mounting ring and the second mounting ring to form the first seal. At the same time, the inner sleeve is tightly fitted with the inner wall of the connector body to form the second sealing line, effectively preventing the leakage of fuel, coolant, lubricating oil and other media, and ensuring the safe and stable operation of the engine under complex working conditions.
