Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4, the utility model is a pressure test detection device for an exhaust pipe, including a pressure detection box 1. A detection groove is opened at the top end of the pressure detection box 1, and a sealing groove is opened at the top end of the detection groove. A sealing cover 2 is arranged on the sealing groove. An elevating mechanism is arranged between the sealing cover 2 and the pressure detection box 1. A driving box 3 is arranged at the top end of the sealing cover 2. An adjusting groove is opened at the bottom end of the sealing cover 2. Bearing seats are arranged at both ends of the adjusting groove. A lead screw 4 is arranged between the two bearing seats. A sliding block 5 and an adjusting gear 6 are arranged on the lead screw 4. A through groove is opened between the inside of the driving box 3 and the adjusting groove. A driving motor 7 is arranged on one side of the driving box 3. A driving gear 8 is arranged between the output end of the driving motor 7 and the through groove. The driving gear 8 is meshed with the adjusting gear 6. A connecting plate 9 is arranged on the sliding block 5. A guiding mechanism is arranged between the connecting plate 9 and the sealing cover 2. Support rods 10 are arranged at one end of the connecting plate 9 and on the sliding block 5. Leakage detection sensors 11 are arranged at the bottom end of the connecting plate 9 and on the two support rods 10. In this embodiment, the sealing cover 2 is moved upward by the elevating mechanism, the exhaust pipe is placed in the detection groove, and then the sealing cover 2 is pressed against the sealing groove by the elevating mechanism. The exhaust pipe is pressurized by using the pressure detection box 1. The pressure detection box 1 is a common pipeline pressure application device in daily life. The two ends of the exhaust pipe are sealed in the detection groove in the pressure detection box 1 by common technical means, and then the exhaust pipe is pressurized. At this time, the leakage detection sensors 11 at the bottom end of the connecting plate 9 and on the two support rods 10 can detect whether there is leakage around the exhaust pipe. Then, by controlling the rotation of the output end of the driving motor 7 to drive the driving gear 8, and the driving gear 8 is meshed with the adjusting gear 6, the adjusting gear 6 can drive the lead screw 4 to rotate. The lead screw 4 can stably rotate at an angle through the two bearing seats, so that the sliding block 5 moves linearly on the lead screw 4. The sliding block 5 drives the connecting plate 9 and the two support rods 10, and can comprehensively detect whether the exhaust pipe leaks.
[0025] In this solution, the lifting mechanism includes a lifting frame 12, a first telescopic mechanism 13, and a fixed box 14. The lifting frame 12 is installed at the top end of the sealing cover 2. The first telescopic mechanism 13 is installed on one side of the pressure detection box 1.

A fixing hole is formed on one side of the lifting frame 12. The fixed column abuts in the fixing hole. By controlling the output end of the first telescopic mechanism 13 to move the lifting frame 12, the lifting frame 12 drives the sealing cover 2 to move upward, so as to facilitate taking out or placing the exhaust pipe in the detection groove. When the sealing cover 2 abuts against the sealing groove, by controlling the output end of the second telescopic mechanism 15 in the fixed box 14 to move the fixed column, the fixed column is inserted into the fixing hole of the lifting frame 12, so that the lifting frame 12 is fixed more firmly, and the sealing cover 2 is fixed more securely.

The guiding block 16 is installed at the top end of the connecting plate 9. The guiding block 16 is slidably connected to the guiding groove. By the guiding block 16 at the top end of the connecting plate 9 being slidably connected to the guiding groove, the connecting plate 9 can move more smoothly in a straight line at the bottom end of the sealing cover 2.
[0027] In this solution, both the guiding block 16 and the guiding groove are in a T-shaped structure. By the T-shaped guiding block 16 and guiding groove, the guiding block 16 can be more stably located in the guiding groove.
[0028] In this solution, multiple guiding mechanisms are provided. By the multiple guiding mechanisms, the connecting plate 9 can move more smoothly in a straight line.
[0029] In this solution, multiple leakage detection sensors 11 are provided on the two support rods 10. By the multiple leakage detection sensors on the two support rods 10, finer leakage situations can be detected better.
[0030] In this solution, the driving motor 7 is a servo motor. The servo motor has the characteristic of high rotation accuracy, so as to drive the gear 8 at one end with high precision.
[0031] In this solution, both the first telescopic mechanism 13 and the second telescopic mechanism 15 are pneumatic telescopic rods. The pneumatic telescopic rods have the characteristic of high movement accuracy, so as to be better used for straight-line movement.
