Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a fuel injection pipe connector for automobiles. Background Technology

[0002] Currently, automotive fuel injectors are precision devices with very high machining accuracy, requiring a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The automotive fuel injector receives the fuel injection pulse signal sent by the ECU and precisely controls the fuel injection quantity. Fuel enters the interior of the automotive injector through the fuel injection pipe for use.

[0003] However, currently, when connecting automotive fuel injection pipes and injectors, hose clamps are often used to secure the pipe joints. During this process, maintenance of the fuel injection pipes and injectors requires the operator to disassemble the hose clamps. Disassembling the hose clamps requires loosening the bolts on their sides, which is inefficient, time-consuming, and labor-intensive, impacting the efficiency of fuel injection pipe and injector maintenance. Therefore, we propose a new automotive fuel injection pipe connector. Utility Model Content

[0004] The main objective of this invention is to provide a fuel injection pipe connector for automobiles, 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 fuel injection pipe connector for automobiles includes a first connecting pipe and a second connecting pipe. Sealing rings are fixedly bonded to the side surfaces of both the first and second connecting pipes. A first mounting frame is fixedly installed at both vertical ends on the outer side of the first connecting pipe, and a second mounting frame is fixedly installed at both longitudinal ends on the outer side of the second connecting pipe.

[0007] A hollow tube is fixedly installed at the top outer side of the first mounting frame. A pushing mechanism is provided inside the hollow tube. Limiting blocks are fixedly installed at both ends of the first connecting tube. An abutting mechanism is provided on the outside of the first connecting tube.

[0008] As an optional solution to the technical solution of this application, the pushing mechanism includes a pushing spring, an extrusion plate is slidably installed inside each hollow tube, a transmission rod is fixedly installed at the middle of the outer side of each extrusion plate, and a pushing spring is movably sleeved on the outer side of each transmission rod, with the two ends of the pushing spring movably attached to the outer side of the extrusion plate and the inner side wall of the hollow tube, respectively.

[0009] By adopting the above technical solution, the extrusion plate and the push spring are connected by a transmission rod, so that after the push block comes into contact with the limit block, the extrusion plate can move synchronously and extrude the push spring to deform it, thus having a restoring pushing force.

[0010] As an optional solution to the technical solution of this application, a connecting rod is fixedly installed at the middle of the other side of each extrusion plate, and the side of the connecting rod is slidably inserted into the second mounting frame. A pushing block is fixedly installed at the end of each connecting rod away from the extrusion plate. A movable groove is opened inside the side of each second mounting frame, and the connecting rod is slidably inserted into the movable groove. A movable plate is fixedly installed on the side of each transmission rod away from the extrusion plate, and the movable plate is movably located outside the hollow tube.

[0011] By adopting the above technical solution, the operator only needs to twist the second connecting pipe when connecting the first and second connecting pipes, so that the side of the pushing block can contact the outside of the limiting block. The limiting block can then abut the pushing block, preventing it from rotating counterclockwise, thus ensuring the stability of the connection between the sides of the first and second connecting pipes. At the same time, it facilitates the disassembly and separation of the first and second connecting pipes, improving the efficiency of maintenance and repair of the fuel injection pipe and fuel injector.

[0012] As an optional solution to the technical solution of this application, abutment blocks are fixedly installed at both ends of the side of the first connecting pipe.

[0013] By adopting the above technical solution, under the structural action of the abutment block, when the first connecting pipe and the second connecting pipe are rotated and twisted, the second mounting frame pushes the inclined surface of the abutment block, which can drive the first connecting pipe to move towards the outside of the second connecting pipe, thereby ensuring the connection stability of the side ends of the first connecting pipe and the second connecting pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A fuel injection pipe connector for automobiles according to this application, comprising a triangular push block disposed on the outside of a first connecting pipe, and a hollow tube inside a second mounting frame on the outside of a second connecting pipe, wherein a drive-connected push block is disposed on the outside of the hollow tube, so that when it is necessary to connect the first and second connecting pipes, only the second connecting pipe needs to be turned, causing it to drive the hollow tube and the push block on its side to rotate synchronously on the outside of the first connecting pipe, so that the push block can contact the inclined surface of the limiting block located on the outside of the first connecting pipe, and then, with the second connecting pipe... When the connecting pipe rotates, the push block is pushed by the limit block, which drives the movable plate to move outward synchronously until the push block moves away from the top surface. Under the reverse pushing action of the push spring, the push block can be driven to return to its original position, so that the side of the push block can contact the outside of the limit block. The limit block can push the push block to prevent it from rotating counterclockwise, thus ensuring the stability of the connection between the side ends of the first connecting pipe and the second connecting pipe. At the same time, it facilitates the disassembly and separation of the first connecting pipe and the second connecting pipe, improving the efficiency of maintenance and repair of the fuel injection pipe and fuel injector.

[0016] 2. A fuel injection pipe connector for automobiles according to the present application, by providing a right-angled triangular abutment block on the outside of the first connecting pipe, when the first and second connecting pipes are rotated and twisted, the second mounting frame rotates into the inside of the first mounting frame. The bottom side of the second mounting frame then rotates and contacts the inclined surface of the abutment block. As the second mounting frame rotates, it pushes the inclined surface of the abutment block, which in turn moves the first connecting pipe toward the outside of the second connecting pipe. This ensures the stability of the connection between the sides of the first and second connecting pipes and further simplifies the connection operation steps of the first and second connecting pipes.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a fuel injection pipe connector for automobiles, wherein a first mounting frame 12 is fixedly installed at both ends of the outer vertical side of the first connecting pipe 1, a second mounting frame 13 is fixedly installed at both ends of the outer longitudinal side of the second connecting pipe 11, an abutment block 3 is fixedly installed at both ends of the side side of the first connecting pipe 1, and the cross-section of the abutment block 3 is a right-angled triangle, and a sealing ring 14 is fixedly bonded to the side surface of the first connecting pipe 1 and the second connecting pipe 11.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a hollow tube 2 is fixedly installed at the top outer side of the first mounting frame 12, and limit blocks 21 are fixedly installed at both ends of the outer side of the first connecting tube 1. An extrusion plate 22 is slidably installed inside each hollow tube 2. A transmission rod 23 is fixedly installed at the middle outer side of each extrusion plate 22. A push spring 24 is movably sleeved on the outer side of each transmission rod 23. The two ends of the push spring 24 are movably attached to the outer side of the extrusion plate 22 and the inner side wall of the hollow tube 2, respectively.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a connecting rod 25 is fixedly installed at the middle of the other side of each extrusion plate 22, and the side of the connecting rod 25 is slidably inserted into the second mounting frame 13. A pushing block 26 is fixedly installed at the end of each connecting rod 25 away from the extrusion plate 22, and the vertical cross-section of the pushing block 26 and the limiting block 21 are both right-angled triangles.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each second mounting frame 13 has an internal movable groove 27 on its side, and the connecting rod 25 is slidably inserted into the movable groove 27. The size of the pushing block 26 is smaller than the inner diameter of the movable groove 27. Each transmission rod 23 has a movable plate 28 fixedly installed on the side away from the extrusion plate 22, and the movable plate 28 is movably located outside the hollow tube 2.

[0025] During operation, when it is necessary to connect the first connecting pipe 1 and the second connecting pipe 11, the second connecting pipe 11 is pushed so that it is close to the outside of the first connecting pipe 1, so that the side end of the second mounting frame 13 is outside the abutment block 3. Then, the second connecting pipe 11 is turned clockwise so that the side end of the second mounting frame 13 can fit against the inclined surface of the abutment block 3. At the same time, the limiting block 21 on the side of the second mounting frame 13 can rotate synchronously and move close to the inclined surface of the limiting block 21. The second connecting pipe 11 is then continuously rotated. After being turned, the inner wall of the second mounting frame 13 adheres to the inclined surface of the abutment block 3, pulling the abutment block 3 and causing it to move the first connecting pipe 1 toward the second connecting pipe 11. At the same time, the pushing block 26 moves synchronously on the inclined surface of the limiting block 21. Under the connecting transmission action of the connecting rod 25, the extrusion plate 22 can move vertically inside the hollow tube 2, extruding the pushing spring 24 and causing it to deform, until the sides of the first connecting pipe 1 and the second connecting pipe 11 are fully adhered. Afterwards, the sealing of the first connecting pipe 1 and the second connecting pipe 11 is achieved by the sealing ring 14. After the pushing block 26 and the limiting block 21 separate, under the reverse pushing action of the pushing spring 24, the movable plate 28 and the pushing block 26 can be driven to return to their original positions. After the side of the pushing block 26 and the side of the limiting block 21 are in contact, the limiting block 21 abuts against the pushing block 26, preventing the first connecting pipe 1 and the second connecting pipe 11 from rotating counterclockwise at will, thus ensuring the connection between the first connecting pipe 1 and the second connecting pipe 11. To ensure stability, when it is necessary to separate the first connecting pipe 1 and the second connecting pipe 11, simply pull the movable plate 28 outward, causing it to move the pushing block 26 away from the outside of the limiting block 21. Then, rotate the second connecting pipe 11 counterclockwise to separate the abutting block 3 and the inner wall of the second mounting frame 13. After separating the first connecting pipe 1 and the second connecting pipe 11, the fuel injection pipe and fuel injector connected to the first connecting pipe 1 and the second connecting pipe 11 can be inspected and maintained.
