Background technique:
The pvc warm edge strip (special pvc granules) is a kind of partition material used between double glass. It has the advantages of good flame retardancy, good sound insulation and strong anti-shock ability, so it is widely used in Among modern buildings. The prior art PVC warm edge strips (special pvc granules) are hollow inside, but it is easy to cause poor airtightness during use, which affects the air tightness of pvc warm edge strips (special Pvc granules). On one aspect, one is the poor airtightness caused by the gap between the glass and the pvc warm edge strip (special pvc granules), and the other is that the tightness of the corners is not tightly connected. Based on the above reasons, the present utility model proposes a PVC warm edge strip (special Pvc granules) for insulating glass with good sealing performance to solve these deficiencies.

Technical realization elements:
The technical problem solved by the utility model is to overcome the defect of poor sealing performance of the prior art and provide a PVC warm edge strip (special Pvc granules) for insulating glass with good sealing performance. The PVC warm edge strip (special Pvc granules) for insulating glass with good sealing performance has the characteristics of good sealing performance and the like.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a PVC warm edge strip (special Pvc granules) for insulating glass with good airtightness, including PVC warm edge strips (special Pvc granules), the PVC warm edge There are two grooves on one side of the strip (special Pvc granules), the PVC warm edge strip (special Pvc granules) is hollow, and one side of the PVC warm edge strip (special Pvc granules) The side walls are inclined, the inner cavity of the pvc warm edge strip (special pvc granules) is provided with a connecting plate, the connecting plate is arranged in an l shape, and both ends of the connecting plate are inserted into the pvc warm edge strip ( Special pvc granules) are provided in an inner cavity, a sealing device is provided at the corner of the inner side wall of the connecting plate, and several clamping devices are provided on the inner side wall of the connecting plate.
Preferably, the sealing device includes a thick rod, one end of the thick rod is fixedly connected to the wall hanging corner inside the connecting plate, the other end of the thick rod is provided with a round hole, and a thin rod is movably connected in the round hole, so One end of the thin rod located in the inner cavity of the round hole is fixedly connected with a first spring, one end of the first spring away from the thin rod is fixedly connected to the bottom surface of the round hole, and one end of the thin rod away from the first spring is fixedly connected with a top plate, and The side wall of the top plate away from the thin rod is fixedly connected with double-sided tape to avoid gaps and sliding at the corners of the pvc warm edge strip (special pvc granules), resulting in poor sealing performance, resulting in good sealing performance.
Preferably, the clamping device includes a movable plate, one side of the movable plate is movably connected to the inner side wall of the connecting plate, and a second spring is fixedly connected to the side wall near the corner of the connecting plate. The second spring is fixedly connected to the side wall of the connecting plate at one end away from the movable plate to realize the fixation of the PVC warm edge strips (special Pvc granules) on both sides, and avoid the air caused by the sliding of the PVC warm edge strips (special Pvc granules). The tightness is not good.
Preferably, the top plate is arranged in an L shape to facilitate the positioning and fixing of the PVC warm edge strips (special Pvc granules).
Preferably, the front and back side walls of the cavity of the groove are fixedly connected with double-sided tapes to avoid the gap between the glass and the PVC warm edge strip (special Pvc granules) resulting in poor air tightness.
Preferably, the movable plate is inclined, the angle between the side wall on the side close to the second spring and the connecting plate is less than 90 degrees, and the movable plate is fixed on the side wall on the side far from the connecting plate. The non-slip mat is connected to make the pvc warm edge strips (special pvc granules) on both sides firmly fixed.

Technical characteristics:
1. A PVC warm edge strip (special Pvc granules) for insulating glass with good airtightness, including PVC warm edge strips (special Pvc granules) (1), characterized in that: the pvc warm edge strips (special Pvc granules) Granules) (1) are provided with two grooves (2) on one side of the side, the PVC warm edge strips (special PVC granules) (1) are hollow, and the PVC warm edge strips (special PVC granules) are hollow. The side wall of (1) is inclined, and the inner cavity of the pvc warm edge strip (special pvc granules) (1) is provided with a connecting plate (3), and the connecting plate (3) is l-shaped The two ends of the connecting plate (3) are inserted into the inner cavity of the pvc warm edge strip (special pvc granules) (1), and the corner of the inner side wall of the connecting plate (3) is provided with a sealing device (4). ), a number of clamping devices (5) are arranged on the inner side wall of the connecting plate (3).

Technical summary
The utility model discloses a PVC warm edge strip (special PVC granular material) for insulating glass with good airtightness, which comprises a PVC warm edge strip (special PVC granular material) and a connecting plate. The utility model is provided with a clamping device, so that the connecting plate can fix the PVC warm edge strips (special Pvc granules) on both sides, effectively avoiding sliding between the PVC warm edge strips (special Pvc granules). The tightness is not good; through the sealing device, the top plate on the thin rod is pushed by the first spring to withstand the gap between the two pvc warm edge strips (special pvc granules), and the double-sided tape is used to stick them tightly to avoid gas Leakage and sliding, good airtightness; double-sided tape is set in the groove, the inner side wall of the glass can be glued tightly to avoid air leakage caused by the gap between the glass and the pvc warm edge strip (special pvc granules), Improve sealing. The utility model has the advantage of good sealing performance.
