[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A rubber tube sealing tool and a rubber tube air tightness detection device, including a cylinder 2, the output end of the cylinder 2 is fixedly connected with a straight rod 3, one end of the straight rod 3 is fixedly connected with a rubber plug 11, and one end of the straight rod 3 is penetrated and connected with an air cylinder 4, the side wall of the rubber plug 11 is in sliding contact with the inner wall of the air cylinder 4, and one end of the air cylinder 4 is movably connected with an inflation rod 14, the end surface of the inflation rod 14 is connected and provided with a sealing bag 5, the outer wall surface of the sealing bag 5 is elastically connected with a spring pin 13, one end of the spring pin 13 is fixedly connected with a through pipe 10, the outer wall surface of the through pipe 10 is penetrated and connected with a hoop 9, two hoop rings 9 are provided, and the two hoop rings 9 are symmetrical to the outer wall of the sealing bag 5 up and down.

[0024] The fixed connection between the cylinder 2 and the straight rod 3 allows the straight rod 3 to directly obtain the power of the cylinder 2, avoiding energy loss. The sliding contact between the rubber plug 11 and the air cylinder 4 allows the rubber plug 11 to be fixedly connected to the straight rod 3 and squeeze the air by sliding motion to facilitate the inflation of the sealing bag 5. The fixed connection between the hoop 9 and the through tube 10 can help to fix the through tube 10 in position, and the fixed connection between the through tube 10 and the spring pin 13 allows the through tube 10 to provide fixed support for the spring pin 13. The hoop 9 is symmetrically arranged on the outer wall of the sealing bag 5, so that after the sealing bag 5 is inflated, the hoop 9 can provide a "snap" effect to help the sealing bag 5 to be stably sealed. The movable connection between the air cylinder 4 and the inflation rod 14 allows the sealing bag 5 to be removed after inflation and sealing, so as to complete subsequent air tightness testing.

[0025] The bottom of the cylinder 2 is fixedly connected to the base 1 , the top of the base 1 is fixedly connected to the clamping member 7 , the top of the clamping member 7 is fixedly connected to the clamping ring 8 , and the inner wall surface of the clamping ring 8 is clamped and fitted with the rubber tube 6 .

[0026] The fixed connection between the clamping member 7 and the clamping ring 8 enables the rubber tube 6 to remain stable when the sealing tool is in place.

[0027] A tripod 12 is fixedly connected to the top of the base 1 , and the top of the tripod 12 is fixedly connected to the outer wall of the air cylinder 4 .

[0028] The fixed connection between the tripod 12 and the gas cylinder 4 can help the gas cylinder 4 to maintain stability and prevent the gas cylinder 4 from shaking due to the displacement movement of the rubber plug 11.

[0029] The sealing bag 5 is made of elastic material, and the center of the sealing bag 5 is consistent with the center of the gas cylinder 4 .

[0030] The sealing bag 5 is made of elastic material, so that the sealing bag 5 can be inflated after receiving the air squeezed by the rubber plug 11, which significantly improves the sealing efficiency with the rubber tube 6.

[0031] The clamping center of the clamping ring 8 is consistent with the center of the rubber tube 6.

[0032] The center of the clamping ring 8 is consistent with that of the rubber tube 6, so that the rubber tube 6 is clamped to the best effect.

[0033] One end of the rubber plug 11 is spaced apart from the inner wall of the gas cylinder 4 .

[0034] The practice of leaving a distance between the rubber plug 11 and the air cylinder 4 allows the rubber plug 11 to squeeze the air and further push the air to the sealing bag 5 .

[0035] The communication center at one end of the gas cylinder 4 is consistent with the center of the sealing bag 5.

[0036] The air cylinder 4 and the sealing bag 5 are arranged in the same center, which is conducive to more uniform transmission of air.

[0037] Working method: When working, place the rubber tube 6 in a suitable position, and then use the clamping member 7 to control the clamping ring 8 to further clamp the rubber tube 6 firmly; then fix the straight rod 3 to the output end of the cylinder 2, and the rubber plug 11 is fixedly connected to one end of the straight rod 3, and the air cylinder 4 is sleeved with the end face of the straight rod 3, so that the air cylinder 4 and the rubber plug 11 are in sliding contact, and further driven by the straight rod 3, the rubber plug 11 slides on the inner wall of the air cylinder 4 and squeezes the internal air, so that the squeezed air is transmitted to the sealing bag 5, and the sealing bag 5 expands evenly after receiving the air, and the hoop 9 and the spring pin 1 3 is arranged in combination, so that the sealing bag 5 will not deviate due to the elastic force of the spring pin 13 when inflated, and further helps the sealing bag 5 to always keep the center consistent with the rubber tube 6. The hoop 9 is symmetrically arranged up and down, so that the inflated sealing bag 5 is clamped and supported, and further helps the rubber tube 6 and the sealing bag 5 to complete the sealing tooling more efficiently. The active connection between the inflation rod 14 and the air cylinder 4 further helps the rubber tube 6 to be removed in time after the sealing tooling is completed, so as to facilitate the subsequent air tightness detection. The device is highly practical and suitable for application.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
