[0002] Spacer is one of the necessary materials for making insulating glass. Its quality is directly related to the use effect, service life and thermal insulation function of insulating glass. When using, the spacer is bent into a frame, plugged and connected, filled with molecular sieve inside, and then pasted between two pieces of glass. Sealant is applied around to make insulating glass. The production of spacer is through the roll of aluminum strip through the forming machine and the mold roll forming, and then the interface is welded by a high-frequency welding machine, and then it is shaped by the mold roller again, and straightened and corrected into a linear aluminum spacer.

[0003] In the prior art, in the insulating glass using the aluminum spacer bending process, the outer side of the bent part is prone to breakage during the bending process of the aluminum spacer, resulting in molecular sieve leakage, thereby affecting the use effect. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a concave-convex spacer for hollow glass. The upper surface of the aluminum spacer is processed into a concave-convex groove shape to form reinforcing ribs, thereby improving the strength of the aluminum spacer, making it less likely to break when bent and not leaking molecular sieves. Air holes are processed on the side walls or bottom of the groove to improve the overall aesthetics of the aluminum spacer. The facade of the concave-convex groove is higher than the height of ordinary spacers, which is beneficial to stability during use.

[0008] Furthermore, a pattern and / or design is provided on the bottom of the groove.

[0009] Furthermore, ventilation holes are provided on the side wall or the groove bottom.

[0010] Furthermore, the weld of the spacer bar body is located on the lower bottom surface, the side surface or the bottom of the concave-convex groove-shaped upper surface of the spacer bar body.

[0013] Furthermore, the connection between the lower surface and the two side surfaces of the spacer bar body is an arc, a bevel or a V-shaped transition structure.
