The rotating rod 9 is rotatably installed on the inner wall of the installation groove 4. Thread grooves 12 are opened at the upper ends of the left and right surfaces of the cooler body 1. The left and right ends of the rotating rod 9 respectively rotatably penetrate into the two thread grooves 12. The two threaded rods 10 are respectively threadedly installed in the two thread grooves 12. The far ends of the two threaded rods 10 are respectively rotatably connected with the two connecting bases 2. First rectangular grooves 13 are opened on the adjacent surfaces of the two threaded rods 10. The two rectangular plates 11 are respectively slidably installed in the two first rectangular grooves 13. The two rectangular plates 11 are both fixedly connected with the rotating rod 9. A first bevel gear 16 is fixedly installed on the outer surface of the rotating rod 9.

[0021] Further, a second bevel gear 17 is fixedly installed at the lower end of the hexagonal rotating rod 5. The second bevel gear 17 is meshed and connected with the first bevel gear 16. A hexagonal limiting groove 18 is opened on the upper surface of the cooler body 1. A hexagonal limiting frame 19 is slidably installed in the hexagonal limiting groove 18. The hexagonal limiting frame 19 is sleeved on the outer surface of the hexagonal rotating rod 5.

[0022] Further, by using a tool to rotate the hexagonal rotating rod 5, the two threaded rods 10 drive the two connecting bases 2 to move away from each other, so as to demount the connecting bases 2, expose the flue gas pipeline inside the cooler body 1, and remove it for more convenient cleaning, and it can be more intuitively seen whether the inside of the flue gas pipeline is cleaned, reducing the cleaning difficulty of the automobile exhaust gas cooler and improving the work efficiency of the staff.

[0023] Further, second rectangular grooves 14 are opened at the lower ends of the left and right surfaces of the cooler body 1. The two first T-shaped grooves 7 are respectively communicated with the inside of the two second rectangular grooves 14. Fixing plates 15 are slidably installed in the two second rectangular grooves 14. The two fixing plates 15 are respectively fixedly connected with the two connecting bases 2.

[0024] Further, second T-shaped grooves 20 are formed in the front surfaces of the two fixing plates 15. Springs 21 are fixedly installed on the rear inner walls of the two second T-shaped grooves 20. T-shaped fixing plates 22 are slidably installed on the inner walls of the two second T-shaped grooves 20. The front ends of the two T-shaped fixing plates 22 are inclined, and the inclined surfaces face the direction of the cooler body 1. The front ends of the two springs 21 are fixedly connected to the two T-shaped fixing plates 22 respectively.

[0025] Further, a second fixing plate 23 is hinged to the cross plate of the U-shaped plate 6, and the second fixing plate 23 is in contact with the front surface of the cooler body 1.

[0026] Further, by driving the two T-shaped fixing plates 22 into the interiors of the two first T-shaped grooves 7 through the two second rectangular grooves 14, the connection base 2 is further fixed, preventing the two threaded rods from incompletely fixing the connection base, resulting in leakage of the coolant and the like inside the cooler body 1, affecting the use efficiency of the vehicle exhaust gas cooler, thereby improving the practicability of the vehicle exhaust gas cooler.

[0027] Working principle: When using this device, the automobile exhaust cooler can be installed on the automobile through the flanges on the two connecting bases 2. When it is used for a long time and its interior needs to be cleaned, the hexagonal limit frame 19 can be removed from the inside of the hexagonal limit groove 18. After removal, the second fixing plate 23 is bent upward so that the second fixing plate 23 is no longer in contact with the cooler body 1. At this time, the U-shaped plate 6 can be pushed closer to the cooler body 1, and the T-shaped top plates 8 on the two rear ends of the U-shaped plate 6 are respectively moved from the inside of the first T-shaped groove 7 to the inside of the second rectangular groove 14, so that the two T-shaped top plates 8 push the T-shaped fixing plates 22 located in the two first T-shaped grooves 7 to the corresponding second T-shaped grooves 20 respectively. The two springs 21 are squeezed and compressed. After the two T-shaped fixing plates 22 enter the inside of the two second T-shaped grooves 20 respectively, use a tool to rotate the upper end of the hexagonal rotating rod 5. Thereby, the second bevel gear 17 fixedly connected to the hexagonal rotating rod 5 is rotated, and the rotation of the second bevel gear 17 drives the first bevel gear 16 meshing with the second bevel gear 17 to rotate, and the rotation of the first bevel gear 16 drives the rotating rod 9 fixedly connected to it to rotate. After the rotating rod 9 rotates, it drives the two rectangular plates 11 fixedly connected to the rotating rod 9 to rotate, and the two rectangular plates 11 drive the corresponding threaded rods 10 to rotate. The two threaded rods 10 rotate inside the two thread grooves 12 respectively and move to both sides. When the two threaded rods 10 move away from each other, they drive the two connecting bases 2 connected thereto respectively to move away from each other, and make the two fixed plates 15 leave from the corresponding second rectangular grooves 14, so that the two connecting bases 2 are removed from the cooler body 1, so that the flue gas duct located inside the cooler body 1 can be exposed, and it is more convenient and intuitive to take it out for cleaning.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
