Description

Technical Field

[0001] This utility model relates to the field of insulated glass technology, specifically to an inert gas filling and sealing structure for soundproof insulated glass. Background Technology

[0002] Soundproof insulated glass is a functional glass product consisting of two or more panes of glass joined together by a sealed frame, with a sealed cavity filled with inert gas in between. Currently, when filling the air between two glass panes with inert gas, the filling needle is inserted into the air hole on the frame to achieve filling. After filling, the butyl rubber strip needs to be pressed into the air hole to seal the air hole the moment the filling needle is pulled out. The key to this step is "speed". Pressing in and pulling out the needle must be done simultaneously to prevent the inert gas from flowing out. In actual use, it was found that the above operation requires a high level of skill and is prone to leakage of inert gas, which leads to a decrease in the gas concentration between the two glass panes and the quality of the finished product cannot be guaranteed. Therefore, it is necessary to invent an inert gas filling and sealing structure for soundproof insulating glass. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an inert gas filling and sealing structure for soundproof insulated glass.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An inert gas-filled sealing structure for soundproof insulated glass includes a frame having two sides and two ends, with a cavity for filling inert gas formed between the two sides and the two ends of the frame. The front and rear sides of the receiving cavity are provided with placement slots for loading glass. Air holes are provided at both ends of the frame. Each of the two air holes is provided with an auxiliary component to prevent the leakage of inert gas when the inflation needle is pulled out of the air hole. The two auxiliary components are distributed in a mirror symmetrical manner.

[0005] Preferably, both of the placement slots have adhesive grooves on their outer sides for storing sealant.

[0006] Preferably, the auxiliary component includes a round tube, which is fixedly embedded inside the air hole. A ring is fixedly connected inside the round tube, and a pressure block is provided on the top of the ring, which is slidably disposed inside the round tube.

[0007] Preferably, the top of the ring is provided with an annular groove one, the bottom of the pressure block is provided with an annular groove two, and a sealing ring is provided between the annular groove one and the annular groove two.

[0008] Preferably, the pressure block has four airflow channels that are evenly distributed in a circular shape.

[0009] Preferably, a connecting strip is fixedly connected inside the circular tube. The connecting strip is located at the bottom of the circular ring, and a prism is slidably embedded on the connecting strip. The top of the prism is fixedly connected to the bottom of the pressure block.

[0010] Preferably, a spring is fixedly connected between the connecting strip and the pressure block, and the spring is sleeved on the outside of the prism.

[0011] Preferably, the sealing ring is made of rubber material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention incorporates an auxiliary component at the air vent. When the inflation needle is pulled out after inflation, the pressure block and ring in the auxiliary component compress the sealing ring, causing the sealing ring to undergo elastic deformation and filling the gap between the ring and the pressure block. This prevents inert gas leakage when the inflation needle is pulled out, eliminating the need to press the butyl rubber strip in at the moment the inflation needle is pulled out. The inert gas filling operation is simplified and requires less operator skill. Attached Figure Description

Detailed Implementation

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Example See attached document Figure 1 - Appendix Figure 10 The present invention provides an inert gas filling and sealing structure for soundproof insulating glass, including a frame 1, the frame 1 having two sides and two ends, and a receiving cavity 2 for filling inert gas is formed between the two sides and two ends of the frame 1. The front and rear sides of the receiving cavity 2 are provided with placement slots 3 for loading glass, and air holes are provided on both ends of the frame 1. Both placement slots 3 have adhesive grooves 4 on their outer sides for storing sealant; When using, place glass in both placement slots 3, such as Figure 6-8 As shown, when placing the glass, it will cover part of the glue groove 4. Then, glass glue is applied between the glass and the frame 1. When applying the glue, some of the glass glue will flow into the glue groove 4, thus wrapping the glass and increasing the sealing effect between the glass and the frame 1. Specifically, the sealant can be polysulfide sealant or silicone sealant; Additionally, air holes are provided at both ends of frame 1. When filling the space between the two panes with inert gas, the inflation needle 15 can be inserted into the lower air hole, and then the inert gas can be filled. During filling, the air between the panes will be expelled by the upper air hole. After the air is basically expelled, the upper air hole can be blocked with silicone sealant. This will prevent the inert gas from flowing out during filling, and the space between the two panes will be filled with inert gas. Specifically, the inert gas used for filling can be argon; In addition, each of the two air holes is equipped with an auxiliary component to prevent the leakage of inert gas the moment the inflation needle 15 is pulled out of the air hole. The two auxiliary components are distributed in a mirror symmetry. The auxiliary components include a round tube 5, which is fixedly embedded inside the air hole. A ring 6 is fixedly connected inside the round tube 5. A pressure block 7 is provided on the top of the ring 6 and is slidably disposed inside the round tube 5. An annular groove 8 is opened on the top of the ring 6 and an annular groove 9 is opened on the bottom of the pressure block 7. A sealing ring 10 is provided between the annular groove 8 and the annular groove 9. Four airflow channels 11 are evenly distributed in a circular shape on the pressure block 7. A connecting strip 12 is fixedly connected inside the round tube 5. The connecting strip 12 is located at the bottom of the ring 6. A prism 13 is slidably embedded on the connecting strip 12 and the top of the prism 13 is fixedly connected to the bottom of the pressure block 7. A spring 14 is fixedly connected between the connecting strip 12 and the pressure block 7 and is sleeved on the outside of the prism 13. The sealing ring 10 is made of rubber material. refer to Figure 9-10 When filling the space between the two glass panes with inert gas, the inflation needle 15 is inserted into the lower circular tube 5. When inserted, the crossbar 16 in the inflation needle 15 will push the prism 13 and the pressure block 7 upward, so that the pressure block 7 can be separated from the ring 6, thereby relieving the compression on the sealing ring 10. At the same time, the spring 14 will be stretched. When the pressure block 7 is separated from the ring 6, the inert gas filling work can be carried out. In this way, the inert gas enters the circular tube 5 and then enters the space between the two glass panes through the airflow channel 11 on the pressure block 7. At this time, a toothpick can be used to push the prism 13 in the upper round tube 5 downward, and then the upper pressure block 7 separates from the ring 6. On the same principle, when filling inert gas, the original air between the glass can be discharged through the upper air hole. When the original air is basically discharged, the toothpick can be taken out. Then, under the action of the spring 14, the upper pressure block 7 and the ring 6 approach each other, and then squeeze the upper sealing ring 10, thus blocking the upper air hole. Then, when continuing to fill inert gas, gas can be prevented from being discharged from the upper air hole. When filling with inert gas, the rubber pad 17 on the inflation needle 15 will contact the bottom of the frame 1, so that gas can be prevented from escaping from the gap between the inflation needle 15 and the frame 1 during inflation. After inflation is complete, the inflation needle 15 is pulled out directly. When pulled out, the spring 14 will slowly rebound, which will allow the pressure block 7 and the prism 13 to slowly move downward and reset. This brings the pressure block 7 closer to the ring 6, thereby squeezing the sealing ring 10. The sealing ring 10 will then undergo elastic deformation and fill the gap between the ring 6 and the pressure block 7. This can prevent the leakage of inert gas when the inflation needle 15 is pulled out, and there is no need to press the butyl rubber strip in at the moment the inflation needle 15 is pulled out. The operation of filling inert gas is simplified and requires less operator skill. After inflation is complete, apply silicone sealant to both round tubes 5 to achieve a permanent seal and prevent leakage of inert gas during later use. The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
