[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: an automobile exhaust bellows that is easy to connect, comprising a bellows 1, the bellows 1 can provide a necessary discharge path for automobile exhaust gas, ensure the normal operation and discharge efficiency of the exhaust system, the bellows 1 is a prior art and will not be described in detail here, the end of the bellows 1 is fixedly connected with a connecting pipe 2, and the automobile exhaust bellows 1 is composed of the bellows 1 and the connecting pipe 2, the outer wall of the connecting pipe 2 is fixedly connected with a T-shaped block 3, the T-shaped block 3 can be plugged into the notch of the fixing block 8, and the entire bellows 1 is preliminarily positioned, the inner wall of the T-shaped block 3 is provided with a limiting mechanism, the inner wall of the bellows 1 is respectively plugged with an exhaust pipe 7 and a pipe 10, one end of the bellows 1 is connected to the exhaust pipe 7, and the other end is connected to the pipe 10, the pipe 10 is connected to the automobile engine, the outer walls of the exhaust pipe 7 and the pipe 10 are respectively fixedly connected with the fixing block 8, and the inner side wall of the fixing block 8 is provided with a limiting groove 9.
[0031] Reference Figure 2 and Figure 4 The outer walls of the exhaust pipe 7 and the pipeline 10 are respectively fixedly connected with a connecting ring 11, and the inner wall of the connecting pipe 2 is fixedly connected with a rubber airbag 12. The rubber airbag 12 is made of soft rubber material and can change its shape and volume by inflation. The connecting ring 11 is plugged into the inner wall of the connecting pipe 2. The side wall of the connecting pipe 2 is provided with a groove, which allows the connecting ring 11 to be plugged into it and cooperate with the rubber airbag 12 to achieve a sealing effect. The connecting ring 11 is in contact with the outer wall of the rubber airbag 12.
[0032] Reference Figure 1-Figure 3When the pressing plate 5 moves to the right, the return spring 4 is compressed. When resetting, the pressing plate 5 is reset by the elastic force of the return spring 4. The other end of the return spring 4 is fixedly connected to the right end of the pressing plate 5. The left end of the pressing plate 5 is fixedly connected to the limit block 6. The limit block 6 is inclined. When squeezed, the limit block 6 can slide along the inner wall of the T-shaped block 3. The limit block 6 penetrates and is slidably connected to the inner wall of the T-shaped block 3. The T-shaped block 3 is respectively provided with notches corresponding to the pressing plate 5 and the limit block 6, which can allow the limit block 6 and the pressing plate 5 to slide along its inner wall. The limit block 6 is plugged into the inner wall of the limit groove 9, and the T-shaped block 3 is plugged into the inner wall of the fixed block 8.
[0033] Working principle: First, when the bellows 1 needs to be disassembled, just press the pressing plate 5 to make the pressing plate 5 move the limit block 6 to the right and compress the return spring 4, so that the limit block 6 and the inner wall of the limit groove 9 are separated, and then the T-shaped block 3 can be separated from the fixing block 8, so that the exhaust pipe 7 and the inner wall of the connecting pipe 2 are separated. At the same time, the connecting ring 11 no longer squeezes the rubber airbag 12, so that the connecting ring 11 is separated from the side wall notch of the connecting pipe 2, and the disassembly of the entire bellows 1 and the connecting pipe 2 is completed. Finally, release the pressing plate 5 and use the reverse elastic force of the return spring 4 to reset the limit block 6.
[0034] When installation and connection are required, it is only necessary to align and plug the T-block 3 with the fixing block 8, so that the connecting pipe 2 is plugged into the exhaust pipe 7 and the connecting ring 11 is plugged into the side wall groove of the connecting pipe 2, so that the connecting ring 11 squeezes the rubber airbag 12 to produce deformation, and the rubber airbag 12 is tightly attached to the inner wall of the side wall groove of the connecting pipe 2 to improve the overall sealing effect. At the same time, when the T-block 3 is plugged into the fixing block 8, the left end of the fixing block 8 will squeeze the inclined surface of the limit block 6, so that the limit block 6 moves to the right with the pressing plate 5 and compresses the reset spring 4. When the limit block 6 and the inner wall of the limit groove 9 coincide, the reverse elastic force of the reset spring 4 is used to reset the pressing plate 5 and the limit block 6, and the limit block 6 and the inner wall of the limit groove 9 are plugged to complete the one-way limit of the entire T-block 3 and the fixing block 8, completing the entire installation and connection process.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
