[0042] The detection board 2 is a long strip structure. The surface of the detection board 2 is provided with three groups of second track grooves 201. The second track grooves 201 are T-shaped structures.

[0043] The sliding block 3 is slidably mounted in the second track groove 201 on the upper end surface of the detection plate 2, a fastening screw 301 is installed on the left side of the upper end surface of the sliding block 3, and a fixing rod 302 is installed on the right side of the upper end surface of the sliding block 3;

[0044] The fixing frame 4 is sleeved on the outside of the fixing rod 302, and the front and rear end surfaces of the fixing frame 4 are respectively provided with a threaded hole, and bolts pass through the threaded holes to fasten the fixing frame 4 and the fixing rod 302;

[0045] The fixing frame 5 has an inverted U-shaped main body, with a connecting screw 502 installed at each end of the fixing frame 5, a first clamping block 501 installed on the inner end surface of the left end vertical plate of the fixing frame 5, and a fastening mechanism installed on the surface of the right end vertical plate of the fixing frame 5.

[0046] Among them, a connecting block 203 is fixedly installed in the middle position of the lower end surface of the detection board 2, and a stepped through hole is opened inside the connecting block 203. A fixing plate 1021 is installed on the upper end surface of the supporting column 102, and the fixing plate 1021 is clamped in the through hole inside the connecting block 203.

[0047] By adopting the above scheme, the technical effect brought about is: the fixing plate 1021 on the upper end surface of the supporting column 102 is rotatably connected to the through hole inside the connecting block 203, so that the detection plate 2 can rotate 360°, and when the worker fixes the pipe of the air conditioner on the surface of the detection plate 2, the worker can rotate the detection plate 2 according to his own convenience, so that when the worker fixes the pipe behind the air conditioner, the worker does not need to move to the rear end of the detection plate 2 by himself, but only needs to rotate the detection plate 2 180°, so that the back of the air conditioner faces the worker, which is convenient for the worker to fix the air conditioning pipe, and the worker does not need to move back and forth, which not only improves the worker's work efficiency but also reduces the worker's workload.

[0048] Among them, three auxiliary support rods 202 are fixedly installed on the lower end surface of the detection plate 2, and the auxiliary support rods 202 are slidably clamped in the first track groove 101 through the triangular blocks at the lower ends.

[0049] By adopting the above scheme, the technical effect brought about is: when the air-conditioning pipeline is installed on the surface of the detection plate 2, a single supporting column 102 makes the detection plate 2 prone to shaking when supporting the detection plate 2, and three auxiliary support rods 202 are installed in a ring shape on the lower end surface of the detection plate 2, so that the three auxiliary support rods 202 can play an auxiliary supporting role and increase the stability of the detection plate 2. At the same time, the auxiliary support rods 202 are slidably mounted in the first track groove 101, so that when the worker rotates the detection plate 2, the three auxiliary support rods 202 will also rotate accordingly.

[0050] A magnet 2021 is installed on the lower end surface of the auxiliary support rod 202 , and an iron bar 1011 is provided on the bottom end surface of the first track groove 101 , and the magnet 2021 fits the iron bar 1011 .

[0051] By adopting the above solution, the technical effect brought about is: the magnet 2021 at the lower end of the auxiliary support rod 202 fits with the iron bar 1011 inside the first track groove 101, and the auxiliary support rod 202 can be fixed in the first track groove 101 on the surface of the base 1 through the attraction between the magnet 2021 and the iron bar 1011. The stability of the detection plate 2 can be increased, so that when the pipeline is detected, the detection plate 2 will not swing left and right.

[0052] Among them, a connecting sleeve 401 is installed on the left and right ends of the fixing frame 4 respectively, and the inner wall of the connecting sleeve 401 is provided with a thread. A connecting screw 502 is installed on the outer end surface of the left end vertical plate of the fixing frame 5, and the connecting screw 502 is threadedly connected to the inside of the connecting sleeve 401.

[0053] By adopting the above scheme, the technical effect brought about is: the pipelines inside the air conditioner are irregular, and many places are arranged in a curved shape, and the connecting screw 502 at the left end of the fixing frame 5 is rotatably connected to the inside of the connecting sleeve 401, so that when the fixing frame 5 rotates, the pipelines in different directions can be fixed, and the distance between the pipeline and the fixing rod 302 is also different. The worker can adjust the distance between the fixing frame 5 and the fixing rod 302 by adjusting the position of the connecting screw 502 inside the connecting sleeve 401, so that the worker can fix pipelines of different specifications.

[0054] Among them, the fastening mechanism includes: an adjusting screw 6, which is threadedly connected to the right end vertical plate of the fixing frame 5, and a knob is installed at the right end of the adjusting screw 6; a second clamping block 7, the inner end surface of the second clamping block 7 is an arc-shaped structure, and the outer end surface of the second clamping block 7 is fixedly installed with a U-shaped frame 701, the front end of the adjusting screw 6 passes through the U-shaped frame 701, and two nuts are also provided on the surface of the adjusting screw 6, the inner end surface of the nut is in contact with the inner and outer end surfaces of the U-shaped frame 701, and the inner end surface of the second clamping block 7 is also evenly installed with rubber balls 702, and the second clamping block 7 has the same structure as the first clamping block 501 and is on the same horizontal line.

[0055] By adopting the above scheme, the technical effect brought about is: when a worker fixes the pipeline, he can place the pipeline between the first clamp block 501 and the second clamp block 7, and then rotate the adjusting screw 6. The adjusting screw 6 can drive the second clamp block 7 to move forward during rotation to fix the pipeline. The inner end surface of the second clamp block 7 and the first clamp block 501 are arc-shaped structures, which can increase the contact area between the pipeline and the first clamp block 501, thereby increasing the stability of the pipeline. At the same time, a rubber ball 702 is also installed on the inner end surface of the second clamp block 7, so that when the second clamp block 7 fixes the pipeline, it can avoid leaving marks on the surface of the pipeline.

[0056] A sensor 5011 is installed inside the first clamping block 501 , and an alarm 8 is installed on the upper end surface of the fixing frame 5 . The alarm 8 is electrically connected to the sensor 5011 .

[0057] By adopting the above scheme, the technical effect brought about is: when inspecting the pipeline, the outlet of the pipeline is first sealed, and then the pipeline is inflated to fill the pipeline with high-pressure gas. When the pipeline is well sealed, the high-pressure gas is stored inside the pipeline and the gas is in a stable state. At this time, the sensor 5011 on the surface of the first clamp 501 cannot feel the pressure change of the pipeline, the alarm 8 does not sound an alarm, and the pipeline inspection is qualified. When there are cracks on the surface of the pipeline, after the high-pressure gas is injected into the pipeline, the gas will be ejected outward from the cracks in the pipeline. When the gas is ejected outward, the pipeline will be subjected to the reaction force of the gas injection, and after the surface sensor 5011 of the first clamp 501 feels the pressure of the pipeline, it will transmit this pressure to the alarm 8 on the upper end face of the fixing frame 5, and then the alarm 8 will sound an alarm, thereby reminding the worker that there is a problem with the sealing of the pipeline. Not only can it indicate that there is a problem, but the approximate location of the leak can also be determined from the position of the alarm 8, which is convenient for later maintenance.

[0058] When in use: the fixing plate 1021 on the upper end surface of the supporting column 102 is rotatably connected to the through hole inside the connecting block 203, so that the detection plate 2 can rotate 360°. When the worker fixes the pipe of the air conditioner on the surface of the detection plate 2, the worker can rotate the detection plate 2 according to his own convenience, so that when the worker fixes the pipe behind the air conditioner, the worker does not need to move to the rear end of the detection plate 2 by himself, but only needs to rotate the detection plate 2 180°. In this way, the back of the air conditioner faces the worker, which is convenient for the worker to fix the air-conditioning pipe. The worker does not need to move back and forth, which not only improves the worker's work efficiency but also reduces the worker's workload. When the air-conditioning pipe is installed on the surface of the detection plate 2, a single supporting column 102 is used for fixing the detection plate 2, the detection plate 2 is prone to shaking, and the lower end surface of the detection plate 2 is annularly installed with three auxiliary support rods 202, so that the three auxiliary support rods 202 can play an auxiliary support role and increase the stability of the detection plate 2. At the same time, the auxiliary support rods 202 are slidably mounted inside the first track groove 101, so that when the worker rotates the detection plate 2, the three auxiliary support rods 202 will also rotate accordingly. The pipeline inside the air conditioner is irregular, and many places are bent. The connecting screw 502 at the left end of the fixing frame 5 is rotatably connected to the inside of the connecting sleeve 401, so that when the fixing frame 5 is rotated, the pipelines in different directions can be fixed. At the same time, the distance between the pipeline and the fixing rod 302 is also different, and the worker can The distance between the fixing frame 5 and the fixing rod 302 can be adjusted by adjusting the position of the connecting screw 502 inside the connecting sleeve 401, so that workers can fix pipes of different specifications. When fixing the pipe, the worker can put the pipe between the first clamping block 501 and the second clamping block 7, and then rotate the adjusting screw 6. The adjusting screw 6 can drive the second clamping block 7 to move forward during rotation to fix the pipe. The second clamping block 7 and the inner end surface of the first clamping block 501 are arc-shaped structures, which can increase the contact area between the pipe and the first clamping block 501, thereby increasing the stability of the pipe. At the same time, the inner end surface of the second clamping block 7 is also installed with a rubber ball 702, so that when the second clamping block 7 fixes the pipe, it can avoid leaving marks on the surface of the pipe. When testing the pipeline, first seal the outlet of the pipeline, and then inflate the pipeline to fill the pipeline with high-pressure gas. When the pipeline is well sealed, the high-pressure gas is stored inside the pipeline and the gas is in a stable state. At this time, the sensor 5011 on the surface of the first clamp 501 cannot feel the pressure change of the pipeline, and the alarm 8 does not sound an alarm. The pipeline inspection is qualified. When there are cracks on the surface of the pipeline, after the high-pressure gas is injected into the pipeline, the gas will be ejected outward from the cracks in the pipeline. When the gas is ejected outward, the pipeline will be subjected to the reaction force of the gas injection. After the surface sensor 5011 of the first clamp 501 feels the pressure of the pipeline, it will transmit this pressure to the alarm 8 on the upper end face of the fixing frame 5.Then the alarm 8 will sound an alarm, thereby reminding the worker that there is a problem with the sealing of the pipeline. Not only can it indicate the problem, but the approximate location of the leak can also be determined from the location of the alarm 8, which is convenient for later maintenance.
