[0027] Example 1, such as Figures 1-4As shown, a stable three-way catalytic converter that is easy to install has two second connecting blocks 2 on both sides of a first connecting block 1. A storage device 3 is installed inside the first connecting block 1, a connecting device 4 is installed on one side of the first connecting block 1, and a support device 5 is installed on the surface of the first connecting block 1. When using the three-way catalytic converter, the catalytic converter body is connected to the exhaust end of the car exhaust pipe. It can convert harmful gases such as CO, HC, and NOx emitted by the car exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Because the catalytic converter body contains a purifying agent, when the high-temperature car exhaust passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of CO, HC, and NOx, promoting them to carry out certain oxidation-reduction chemical reactions. Among them, CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperature; HC compounds are oxidized into water (H2O) and carbon dioxide at high temperature; and NOx is reduced into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thus purifying the car exhaust.

[0028] Reference Figure 2The connecting device 4 includes a fixing ring 401, which is fixedly connected to the side of the second connecting block 2 closest to the first connecting block 1. A rectangular groove 402 is evenly formed on the surface of the fixing ring 401. A fixing frame 403 is slidably connected to the inner wall of the rectangular groove 402. The fixing frame 403 is fitted onto the surface of one side of the first connecting block 1. A positioning groove 410 is formed on one side of the first connecting block 1. A connecting ring 411 is provided on the inner wall of the positioning groove 410. The end of the connecting ring 411 away from the positioning groove 410 is fixedly connected to one side of the second connecting block 2. When using the connecting device 4, the connecting ring 411 is slid to the positioning groove 410. The fixing frame 403 is slid into the rectangular groove 402 and fitted onto the surface of the first connecting block 1, thus connecting the first connecting block 1 and the second connecting block 2 together. A high-temperature resistant silicone coating with excellent high-temperature resistance, formulated from organic resin, heat-resistant pigments, additives, and solvents, is applied to the connection point to achieve a sealing effect. Reverse operation allows the first connecting block 1 and the second connecting block 2 to be disassembled, facilitating the replacement of the purifying agent inside the storage device 3. A first connecting block 403 is fixedly connected to one side of the inner wall of the rectangular groove 402. A damping rod 404 is provided, with its top fixedly connected to the bottom of a fixed frame 403. A first spring 405 is fitted onto the surface of the first damping rod 404. One end of the first spring 405 is fixedly connected to one side of the inner wall of the rectangular groove 402, and the end of the first spring 405 near the first damping rod 404 is fixedly connected to the bottom of one side of the fixed frame 403. By pulling the fixed frame 403 towards the inner wall of the rectangular groove 402 through the first spring 405, the fixed frame 403 can be effectively confined inside the rectangular groove 402. A sliding ring 406 is slidably fitted onto the surface of the first connecting block 1. A first bolt 407 is threaded through one side of the ring 406. The first bolt 407 is threaded into one side of the fixed frame 403. The fixed frame 403 is fixed to one side of the sliding ring 406 by the first bolt 407, so as to prevent the catalyst from vibrating and causing the fixed frame 403 to move away from the interior of the rectangular groove 402. A locking groove 408 is opened on one side of the sliding ring 406. A rubber ring 409 is rotatably fitted on the inner wall of the locking groove 408. The rubber ring 409 is fixedly connected to one end of the first bolt 407. The rubber ring 409 can effectively restrict the first bolt 407 to one side of the sliding ring 406.

[0029] Reference Figure 3 and Figure 4The support device 5 includes a first fixed sleeve 501 and a second fixed sleeve 505. The first fixed sleeve 501 is fitted onto the surface of the first connecting block 1, and the second fixed sleeve 505 is fitted onto the surface of the vehicle exhaust pipe. A movable sleeve 502 is slidably connected to the inner wall of the first fixed sleeve 501. A fixed groove 503 is formed at the end of the movable sleeve 502 away from the first fixed sleeve 501. A rotating rod 504 is fixedly connected to the inner wall of the fixed groove 503. A support strip 509 is rotatably fitted onto the surface of the rotating rod 504. The end of the support strip 509 away from the rotating rod 504 is located in the inner wall of the second fixed sleeve 505. When using the support device 5, the first fixed sleeve 501 is... A second fixing sleeve 505 is fitted onto the surface of the first connecting block 1, and a movable sleeve 502 is slid out of the inner wall of the first fixing sleeve 501. The support bar 509 is then manually rotated, with one end of the support bar 509 away from the rotating rod 504 positioned within the inner wall of the second fixing sleeve 505. The catalyst is then supported at one end of the vehicle's exhaust pipe by the first fixing sleeve 501, the second fixing sleeve 505, and the support bar 509. A second damping rod 506 is fixedly connected to one side of the inner wall of the first fixing sleeve 501, with one end of the second damping rod 506 away from the first fixing sleeve 501 and one end of the movable sleeve 502 fixed together. The connection is as follows: a second spring 507 is sleeved on the surface of the second damping rod 506. One end of the second spring 507 is fixedly connected to one side of the inner wall of the first fixed sleeve 501. The end of the second spring 507 near the second damping rod 506 is fixedly connected to one end of the movable sleeve 502. When the support device 5 is not used, the movable sleeve 502 is pulled towards the inner wall of the first fixed sleeve 501 by the second spring 507, thereby storing the movable sleeve 502 inside the first fixed sleeve 501. The surfaces of the first fixed sleeve 501 and the second fixed sleeve 505 are both threaded with second bolts 508, which are used to press the first connecting block 1. The surface of the support bar 509 is the same as the surface of the car exhaust pipe. This allows the first fixing sleeve 501 to be fixed to the surface of the first connecting block 1, and the second fixing sleeve 505 to be fixed to the surface of the car exhaust pipe. The end of the support bar 509 away from the rotating rod 504 is threaded with a threaded rod 510. The bottom of the threaded rod 510 is threaded with a semi-circular sleeve 511. The semi-circular sleeve 511 is fitted into the inner wall of the second fixing sleeve 505. The threaded rod 510 is manually rotated, which causes the semi-circular sleeve 511 to be pressed into the inner wall of the second fixing sleeve 505. This effectively restricts the end of the support bar 509 away from the rotating rod 504 to the surface of the second fixing sleeve 505.

[0030] Working principle: When using a three-way catalytic converter, the main body of the converter is connected to the exhaust outlet of the car's exhaust pipe. It converts harmful gases such as CO, HC, and NOx emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Because the catalytic converter contains a purifying agent, when the high-temperature exhaust gas passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions. Specifically, CO is oxidized at high temperatures into colorless and non-toxic carbon dioxide; HC compounds are oxidized at high temperatures into water (H2O) and carbon dioxide; and NOx is reduced into nitrogen and oxygen. These three harmful gases are thus transformed into harmless gases, purifying the car's exhaust gas. When connecting device 4, the connecting ring 411 is slid into the positioning groove 410, and then the fixing frame 403 is slid into the rectangular groove 402. The first spring 405 pulls the fixing frame 403 towards the inner wall of the rectangular groove 402, effectively confining the fixing frame 403 within the rectangular groove 402. The fixing frame 403 is then fitted onto the surface of one side of the first connecting block 1, and the first bolt 407 secures the fixing frame 403 to one side of the sliding ring 406, preventing vibration of the catalyst from causing the fixing frame 403 to move away from the interior of the rectangular groove 402. The rubber ring 409 effectively confines the first bolt 407 to one side of the sliding ring 406. This allows the first connecting block 1 and the second connecting block 2 to be connected together. Then... The joint is coated with an organosilicon high-temperature resistant coating, formulated with organic resin, heat-resistant pigments, additives, and solvents, which has excellent high-temperature resistance, thereby achieving a sealing effect. Reverse operation allows the first connecting block 1 and the second connecting block 2 to be disassembled, facilitating the replacement of the purifying agent inside the storage device 3. When using the support device 5, the first fixing sleeve 501 is fitted onto the surface of the first connecting block 1, and the second fixing sleeve 505 is fitted onto the surface of the vehicle exhaust pipe. The second bolt 508 is used to press against the surfaces of the first connecting block 1 and the vehicle exhaust pipe, thus effectively fixing the first fixing sleeve 501 to the surface of the first connecting block 1 and the second fixing sleeve 505 to the surface of the vehicle exhaust pipe. The movable sleeve 502 can then slide out of the first fixing... The inner wall of the sleeve 501 is then manually controlled to rotate the support bar 509, and the end of the support bar 509 away from the rotating rod 504 is placed in the inner wall of the second fixed sleeve 505. The threaded rod 510 is manually controlled to rotate, thereby causing the semi-circular sleeve 511 to be pressed into the inner wall of the second fixed sleeve 505. This can effectively restrict the end of the support bar 509 away from the rotating rod 504 to the surface of the second fixed sleeve 505. Then, the catalyst is supported at one end of the car exhaust pipe by the first fixed sleeve 501, the second fixed sleeve 505 and the support bar 509. When the support device 5 is not used, the moving sleeve 502 is pulled towards the inner wall of the first fixed sleeve 501 by the second spring 507, thereby storing the moving sleeve 502 inside the first fixed sleeve 501.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
