[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1:
[0026] Please refer to Figure 1-3 A sealing detection structure for the production of thermos flasks, wherein a top plate 7 is fixedly installed on the top of the vertical plate 2, a driver 8 is fixedly installed on the upper end of the top plate 7, a zoom rod 9 is fixedly installed on the bottom of the driver 8, the zoom rod 9 penetrates the top plate 7 and is connected with the driver 8, a pressing plate 10 is fixedly installed on the bottom zoom end of the zoom rod 9, four through holes 11 are opened on the surface of the pressing plate 10, the four through holes 11 are arranged in a rectangular array on the pressing plate 10, and vertical rods 5 are penetrated in the four through holes 11, a collar 12 is fixedly installed in the middle position of the bottom of the pressing plate 10, a sealing ring 13 is installed in the collar 12, an air outlet 14 is opened in the middle position of the inner part of the collar 12, and the material used for the collar 12 is soft silicone material.
[0027] Working principle: When the sensor 4 senses that the thermos flask is placed at the bottom of the ring 12, the driver 8 at the top will control the zoom rod 9 to descend. After the zoom rod 9 is accommodated, the pressure plate 10 at the bottom will drive the ring 12 to descend. The ring 12 is set on the bottle mouth of the thermos flask. Then, because there are four through holes 11 on the pressure plate 10, the pressure plate 10 can be lowered through the vertical rod 5. In this way, the pressure plate 10 has a limited effect. Then, when the ring 12 is set on the bottle mouth of the thermos flask, it is connected to the pressure plate 10. An external gas supply device is used to transport gas into the thermos flask from the gas outlet 14 opened in the middle of the inner wall of the ring 12. Then, when the gas is transported into the thermos flask, the sealing ring 13 can prevent the gas from leaking through the gap during the gas transportation process. Because the material used for the ring 12 is soft silicone, the surface of the thermos flask will not be scratched when the ring 12 descends, thereby preventing the gas from leaking from the gap and affecting the value of the test result when the sealing of the thermos flask is tested.
[0028] Embodiment 2:
[0029] Please refer to Figure 1-3 A sealing detection structure for the production of thermos flasks, wherein two vertical plates 2 are fixedly installed on both sides of the upper surface of the bottom plate 1, and a feed port 3 is opened on the surface of the vertical plates 2 on both sides, and a sensor 4 is installed in the middle position of the upper surface of the bottom plate 1, and four vertical rods 5 are fixedly installed on the upper surface of the bottom plate 1, and the four vertical rods 5 are arranged in a rectangular array on the upper surface of the bottom plate 1, and four springs 6 are fixedly installed on the upper surface of the bottom plate 1, and the four springs 6 are sleeved on the outer surface of the vertical rods 5.
[0030] Working principle: The thermos flask can be fed into the feeding port 3 opened on one side of the vertical plate 2. Then, when the sensor 4 installed on the bottom plate 1 senses that the thermos flask is placed at the bottom of the sleeve ring 12, the driver 8 will drive the zoom rod 9 to drive the pressing plate 10 to press down. Then, because the four passages on the pressing plate 10 are penetrated by the vertical rods 5, when the pressing plate 10 is pressed down, the springs 6 installed on the outer surfaces of the four vertical rods 5 will slow down the speed of pressing down to prevent the thermos flask from being damaged due to pressing down too quickly.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
