When it is necessary to seal the connection between the mounting tube 7 and the connecting tube 2 8, the mounting tube 7 is fitted with the connecting tube 2 8, and then the collar 11 is rotated so that the collar 11 can move upward, so that the collar 11 can seal the connection between the mounting tube 7 and the connecting tube 2 8, and when the mounting tube 7 is separated from the connecting tube 2 8, the collar 11 is continued to be rotated so that the collar 11 can be conveniently detached from the outside of the mounting tube 7 and the connecting tube 2 8, so that the collar 11 can be conveniently replaced, so that the detection efficiency of the equipment will not be reduced, and the detection sealing is better, thereby making the detection quality higher, so that the device is more economical to use.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, in order to improve the sealing performance of the collar 11 at the connection between the mounting tube 7 and the second connecting tube 8, two sealing grooves 19 are provided inside the outer side of the mounting tube 7, and a sealing groove 20 is provided inside the outer side of the second connecting tube 8. The upper and lower sides of the inner wall of the collar 11 are fixedly connected with sealing rings 12, and the sealing rings 12 fit the inside of the sealing groove 10. When the collar 11 moves upward, the upper sealing ring 12 fits the sealing groove 20, thereby sealing the connection between the mounting tube 7 and the second connecting tube 8. When the collar 11 moves upward, the sealing ring 12 can be separated from the inside of the sealing groove 10, and then when the lower sealing ring 12 fits the upper sealing groove 10, the upper sealing ring 12 fits the sealing groove 20, thereby making the connection between the collar 11 and the mounting tube 7 and the second connecting tube 8 fit more tortuously.

[0028] Embodiment 3

[0029] On the basis of Example 2, in order to achieve better sealing of the connection between the mounting tube 7 and the connecting tube 2 8, a mounting groove 13 is provided on the inner side of the bottom end of the connecting tube 2 8, and a plurality of limit blocks 14 are fixedly connected to the inside of the mounting groove 13. An extension ring 15 is fixedly connected to the inner side of the top end of the mounting tube 7, and a plurality of limit grooves 16 are provided on the outer side of the extension ring 15. The limit blocks 14 match the limit grooves 16, and the limit blocks 14 are clamped in the inside of the limit grooves 16, so that the connection between the mounting tube 7 and the connecting tube 2 8 is more tortuous, thereby making the connection sealing better. When the mounting tube 7 fits with the connecting tube 2 8, the extension ring 15 is able to enter the interior of the mounting groove 13 and can squeeze the limit block 14 to produce deformation. When the extension ring 15 fits with the mounting groove 13, the limit block 14 is able to perform a reset movement, so that the limit block 14 can fit with the interior of the limit groove 16, thereby making the mounting tube 7 and the inner side of the connecting tube 2 8 more tightly connected, making it difficult for the water inside the mounting tube 7 and the connecting tube 2 8 to leak, thereby making the connection sealing between the mounting tube 7 and the connecting tube 2 8 better.

[0030] Embodiment 4

[0031] On the basis of embodiment three, in order to facilitate the replacement of the mounting tube 7, a placement groove 3 is provided inside the top end of the connecting tube 2, and a clamping block 5 is provided on the lower side of the placement groove 3. The bottom end of the mounting tube 7 is fixedly connected with a placement block 6, and the placement block 6 is slidably connected to the inside of the placement groove 3. The placement groove 3 limits the placement block 6, so that the placement block 6 can slide stably, and the bottom end of the placement block 6 is fixedly connected with a clamping block 5, and the clamping block 5 is slidably connected to the placement groove 3. The placement groove 3 is used to squeeze the clamping block 5 to produce deformation. The outer part of the clamping block 5 is trapezoidal in design, and the curvature of the lower side is larger than that of the upper side, so that the clamping block 5 can be conveniently slid into the inside of the clamping groove 4, and be squeezed by the clamping groove 4 to produce deformation, and the clamping block 5 can be detached from the inside of the clamping groove 4, and the clamping block 5 matches the clamping groove 4, and the clamping block 5 is clamped in the inside of the clamping groove 4, so that the mounting tube 7 is connected to the connecting tube 2. When the mounting tube 7 needs to be installed, the bottom end of the mounting tube 7 is fitted with the top end of the connecting tube 2, so that the block 5 and the placement block 6 can slide into the interior of the placement groove 3. During this process, the block 5 is squeezed and deformed by the placement groove 3, so that the block 5 can perform a reset movement, so that the block 5 can be engaged with the groove 4. Conversely, by pulling the mounting tube 7 upwards, the arc surface on the upper side of the block 5 can fit the interior of the groove 4 and slide, so that the block 5 can be easily detached from the interior of the groove 4, so that the mounting tube 7 can be easily disassembled.

[0032] In actual use, by fitting the bottom end of the mounting tube 7 with the top end of the connecting tube 1 2, the clamping block 5 and the placing block 6 can slide into the inside of the placing groove 3. In this process, the clamping block 5 can be squeezed and deformed by the placing groove 3, so that the clamping block 5 can make a reset movement, so that the clamping block 5 can be engaged with the clamping groove 4. Then the mounting tube 7 is fitted with the connecting tube 2 8, so that the extension ring 15 can enter the inside of the mounting groove 13 and can squeeze the limit block 14 to produce deformation. When the extension ring 15 fits with the mounting groove 13, the limit block 14 can make a reset movement, so that the limit block 14 can fit with the inside of the limit groove 16, so that the inner side of the mounting tube 7 and the connecting tube 2 8 is more tightly connected, so that the water inside the mounting tube 7 and the connecting tube 2 8 is not easy to leak, thereby making the mounting tube 7 and the connecting tube 2 8 The connection sealing of tube 2 8 is better. By fitting the mounting tube 7 with the connecting tube 2 8, the ring 11 is rotated so that the ring 11 can move upward, so that the sealing ring 12 can be detached from the inside of the sealing groove 1 9. Then, when the lower sealing ring 12 fits with the upper sealing groove 1 9, the upper sealing ring 12 fits with the sealing groove 2 10, so that the connection between the ring 11 and the mounting tube 7 and the connecting tube 2 8 is more tortuous. Moreover, when the mounting tube 7 is separated from the connecting tube 2 8, the ring 11 is continued to be rotated so that the ring 11 can be conveniently detached from the outside of the mounting tube 7 and the connecting tube 2 8, so that the ring 11 can be conveniently replaced, so that the detection efficiency of the equipment will not be reduced, and the detection sealing is better, so that the detection quality is higher, and the use economy of the device is better.
