In the production of potting compounds and sealants for solar panels, the vacuum pumping tube of the vacuum packaging machine is used to connect the vacuum sealer;

[0003] When vacuum pumping is required, the vacuum tube connecting pipe will gradually become flattened due to being in a negative pressure state for a long time, resulting in a smaller gap in the middle of the vacuum tube, affecting the vacuum pumping efficiency. It is necessary to frequently replace the vacuum pumping tube, which is cumbersome to operate and easily affects the efficiency. Summary of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A connection structure of a vacuum pumping tube of a vacuum sealer, including a vacuum tube main body. A flat tube is integrally formed on the right side of the vacuum tube main body. A support tube is slidably connected inside the flat tube. Rubber plates are adhesively connected to both sides of the support tube. A number of support rods are arranged inside the support tube. The diameter of the vacuum tube main body is 12 mm, the thickness of the vacuum tube main body is 0.7 mm, the vacuum tube main body and the flat tube are of an integrally formed structure, and the length is 300 mm.

[0006] Preferably, the inside of the flat tube is slidably connected to the outer walls of the two rubber plates, and the length of the flat tube is greater than the length of the support tube.

[0007] Preferably, the flat tube is made by flattening the vacuum tube main body, and both ends of the support tube are arranged in an arc shape.

[0008] Preferably, a number of the support rods are linearly arrayed inside the support tube, and the distances between the support rods are equal.

[0009] Preferably, a fixing block is sleeved on the outer wall of the vacuum tube main body, and an air pipe joint is movably sleeved on the side of the vacuum tube main body away from the flat tube.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The connection structure of the vacuum pumping tube of this vacuum sealer is provided with a support tube to support the flat tube, preventing the flat tube from deforming under negative pressure and affecting gas flow. The support rod indirectly supports the flat tube, and the thickness of the main body of the vacuum tube is increased. Compared with the existing vacuum tube, the thickness is increased by 0.2 mm, making the structure stronger and avoiding deformation under negative pressure, solving the problem that the existing vacuum tube needs to be frequently replaced, the operation is cumbersome, and it is easy to affect the efficiency.

[0012] 2. The connection structure of the vacuum pumping tube of this vacuum sealer can achieve the effect of restricting the movement of the support tube by slidingly connecting the inside of the flat tube with two rubber plates. Because the rubber plate has a certain elasticity, it can cooperate with the extrusion of the support tube to fix the support tube inside the flat tube. The length of the flat tube is greater than the length of the support tube, which can achieve the effect of hiding the support tube and avoid affecting the normal use of the vacuum tube.
