[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 and Figure 2 , the embodiment of the utility model provides a device for detecting air tightness of a water channel of a cooler in a confined space, comprising a mounting plate 1, a first driving member 2, a second driving member 3, a fixing member 4, a transfer rod 5, a plug 6 and an expansion sealing member 7;

[0023] Among them, the first driving member 2 is connected to one side of the lower end of the mounting plate 1, and the second driving member 3 is connected to the other side of the lower end of the mounting plate 1; the lower end of the shell of the second driving member 3 is connected to the fixing member 4, the driving head of the second driving member 3 is connected to the upper end of the transfer rod 5, and the lower end of the transfer rod 5 extends from the central through hole of the fixing member 4; the lower end of the transfer rod 5 extending from the central through hole of the fixing member 4 is connected to the plug 6; an expansion seal 7 is provided between the plug 6 and the fixing member 4.

[0024] In this embodiment, the first driving member 2 adopts a cylinder, and the driving head of the first driving member 2 is connected to the mounting plate 1; a guide rod 8 is also connected between the first driving member 2 and the mounting plate 1; the second driving member 3 adopts a cylinder, and the tail end of the second driving member 3 is connected to the mounting plate 1.

[0025] Specifically, the first driving member 2 can drive the second driving member 3 with the plug 6 and the expansion seal 7 to move downward, thereby making the plug 6 and the expansion seal 7 enter the water pipe. At this time, the piston driving head of the second driving member 3 retracts back and drives the plug 6 to move upward through the transfer rod 5. Since the fixing member 4 does not move, the expansion seal 7 is squeezed in the water pipe and expands, thereby achieving the effect of sealing the water pipe.

[0026] Among them, the blocking direction can be determined according to the size of the space of different products, and the size of the cylinder used by the first driving member 2 and the second driving member 3 and the length of the transfer rod 5 can be changed.

[0027] In this embodiment, the upper end of the fixing member 4 and the housing of the second driving member 3 are fixedly connected by bolts; the fixing member 4 is formed with a first cylindrical portion 9 and a second cylindrical portion 10, and the first cylindrical portion 9 and the second cylindrical portion 10 are connected to each other.

[0028] Specifically, since the fixing member 4 is fixedly connected by bolts, when the second driving member 3 is actuated, the fixing member 4 itself does not move, but the adapter rod 5 passing through the inside of the fixing member 4 can move upward driven by the piston driving head of the second driving member 3, and then the expansion seal 7 is squeezed in the water pipe to expand, thereby achieving the effect of sealing the water pipe.

[0029] The first cylindrical portion 9 and the second cylindrical portion 10 are of an integrated design, and the outer diameter of the second cylindrical portion 10 is relatively small, so as to reduce the space occupied by the fixing member 4 without affecting the function of the fixing member 4 .

[0030] In this embodiment, the lower end of the adapter rod 5 is connected to the plug 6 via a thread; the connection between the adapter rod 5 and the plug 6 is located inside the expansion seal 7; the expansion seal 7 is made of rubber, and the upper end of the expansion seal 7 contacts the lower end of the second cylindrical portion 10.

[0031] Specifically, the plug 6 is threaded for easy replacement. Since the connection between the adapter rod 5 and the plug 6 is located inside the expansion seal 7, when the adapter rod 5 drives the plug 6 to move upward, the plug 6 can squeeze the soft rubber expansion seal 7, and the squeezed expansion seal 7 expands in the water pipe.

[0032] In this embodiment, the outer diameters of the second cylindrical portion 10 and the expansion seal 7 are the same, and the outer diameter of the plug 6 is slightly smaller, so that it can extend into the interior of the water pipe to be sealed.

[0033] In this embodiment, the tail end of the first driving member 2 is fixed on the working platform; the expansion seal 7 and the plug 6 extend into the water pipe to seal the water pipe. By placing the corresponding product airtight tooling on the working platform, placing the product on the airtight tooling, starting the switch, the second driving member 3 drives the plug 6 into the water pipe, the expansion seal 7 expands and seals the water pipe, and starting the matching airtightness instrument product to inflate, and then spraying foaming water to observe whether there is a bubble phenomenon, so as to judge whether there is a leak in the test piece and judge the sealing of the test piece.

[0034] In summary, the utility model is provided with a mounting plate 1, a first driving member 2, a second driving member 3, a fixing member 4, a transfer rod 5, a plug 6 and an expansion seal 7; the first driving member 2 is connected to one side of the lower end of the mounting plate 1, and the second driving member 3 is connected to the other side of the lower end of the mounting plate 1; the lower end of the housing of the second driving member 3 is connected to the fixing member 4, the driving head of the second driving member 3 is connected to the upper end of the transfer rod 5, and the lower end of the transfer rod 5 extends from the central through hole of the fixing member 4; the lower end of the transfer rod 5 extending from the central through hole of the fixing member 4 is connected to the plug 6; an expansion seal 7 is arranged between the plug 6 and the fixing member 4. The first driving member 2 can drive the second driving member 3 with the plug 6 and the expansion seal 7 to move downward, thereby making the plug 6 and the expansion seal 7 enter the water pipe, at this time, the piston driving head of the second driving member 3 retracts back, and drives the plug 6 to move upward through the transfer rod 5; because the fixing member 4 is immovable; the expansion seal 7 is squeezed in the water pipe and expands, thereby achieving the effect of sealing the water pipe. The size of the cylinder used by the first driving member 2 and the second driving member 3 and the length of the adapter rod 5 can be changed according to the size of the space of different products; the direction of blocking can be determined. Since the fixing member 4 is fixedly connected by bolts, when the second driving member 3 is in motion, the fixing member 4 itself does not move, but the adapter rod 5 passing through the inside of the fixing member 4 can move upward under the drive of the piston drive head of the second driving member 3, so that the expansion seal 7 is squeezed in the water pipe to expand, thereby achieving the function of sealing the water pipe. The first cylindrical part 9 and the second cylindrical part 10 are designed in an integrated manner, and the outer diameter of the second cylindrical part 10 is small, which reduces the space occupied by the fixing member 4 without affecting the function of the fixing member 4. The plug 6 is threaded for easy replacement. Since the connection between the adapter rod 5 and the plug 6 is located inside the expansion seal 7, when the adapter rod 5 drives the plug 6 to move upward, the plug 6 can just squeeze the rubber soft expansion seal 7, and the squeezed expansion seal 7 expands in the water pipe. By placing the corresponding product airtight tooling on the work platform, placing the product on the airtight tooling, starting the switch second driving member 3 to drive the plug 6 into the water pipe, the expansion seal 7 expands and blocks the water pipe, starting the matching airtight instrument product to inflate, and then using foaming water to observe whether there is a bubble phenomenon, so as to judge whether there is a leak in the test piece to judge the sealing of the test piece. The utility model can change the detection airtightness in a limited space, is easy to operate, can quickly and effectively seal the water pipe port, ensure that the sealing of the cooler water pipe is effectively detected, save manpower, reduce the problem of difficulty in detection due to limited space, and improve production efficiency.
