Description

Technical Field

[0001] The invention relates to the technical field of insulating glass, and in particular to an insulating glass spacer and a processing method thereof, a spacer assembly, a door and a window. Background Art

[0002] At present, the insulating glass on the market is generally a glass product that uses spacers to evenly support and separate two or more pieces of glass and seal them around the edges, so that a space for dry gas is formed between adjacent glass layers. Insulating glass has the advantages of good heat insulation, sound insulation, beautiful and practical, and can reduce the weight and energy consumption of buildings. With the increasing global requirements for energy conservation and emission reduction, the use of insulating glass in energy-saving buildings is becoming more and more widespread. The spacer is the core component of insulating glass. The spacer is used to ensure that the appropriate spacing between adjacent glass layers of insulating glass is fixed, and to ensure that the gas in the spacing remains dry to achieve the effect of heat insulation and sound insulation of insulating glass.

[0003] Since the spacer bars need to ensure that the gas within the spacing remains dry, the spacer bars between adjacent glass layers need to form a closed ring to keep the gas within the ring dry. The spacer bars between the glass layers need to be connected to form a closed ring. In the existing insulating glass, a connector is provided at each of the four corners of the insulating glass, and the spacer bars are connected to the connector to form a frame, thereby forming a closed ring. However, in the above method, additional connectors are required to achieve the connection of the spacer bars, which invisibly increases the types of spare parts. Moreover, the filling of the desiccant in the spacer bars after the frame is formed is also the most problematic link in the current process. The spacer bars after the frame is formed need to be filled after drilling by the filling machine, which results in serious loose materials and leakage, and the exposure time of the desiccant in the air is uncontrollable. Long-term exposure will reduce the adsorption capacity of the desiccant. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a hollow glass spacer and its processing method, a spacer assembly, a door and a window, which can make the outline of the spacer bar insertion point smaller than the outline size of the adjacent spacer bars to achieve mutual insertion between the spacer bars.

[0015] The distance between the two opposite side walls of the second groove gradually decreases in the direction close to the abutment point between the third side wall and the fourth side wall until they fit together.

[0016] Preferably, at the sheet structure, the first side wall is bent outward along its midline so that the inner wall of the first side wall below the midline is in close contact with the inner wall of the first side wall above the midline;

[0037] In order to make the outline of the spacer bar insertion point smaller than the outline size of the adjacent spacer bars so as to realize the mutual insertion between the spacer bars, a hollow glass spacer bar 100 is proposed in the present application. Figure 1 FIG. 1 is a schematic diagram of the three-dimensional structure of the insulating glass spacer in an embodiment of the present invention. Figure 1As shown, the hollow glass spacer 100 may include: a body 1 with an axis, which has a first side wall 11 and a second side wall 12 opposite to each other, and a third side wall 13 and a fourth side wall 14 opposite to each other, wherein the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 form a receiving cavity; at at least one end of the body 1, the third side wall 13 and the fourth side wall 14 are pressed in a direction perpendicular to the third side wall 13 to form a sheet structure 15, and the two ends of the sheet structure 15 located in the direction of the first side wall 11 and the second side wall 12 are respectively rolled around the axis into a curved shape.

[0038] In the present application, the insulating glass spacer 100 can be directly formed by flattening the ends of the conventional spacer with a generally rectangular cross section and then winding them. The entire processing process is convenient and quick and can be efficiently mass-produced. After the above-mentioned insulating glass spacer 100 is processed and formed, the contour of the curved end of the main body 1 of the insulating glass spacer 100 can be made smaller than the contour size of the adjacent conventional spacer, so that the end of the insulating glass spacer 100 can be directly inserted into the adjacent conventional spacer, thereby realizing the mutual plug-in between the spacers. In the process of plug-in of the entire spacer, there is no need to introduce other connectors for connecting the spacers, which effectively reduces the types of spare parts required for installing insulating glass.

[0039] In order to better understand the insulating glass spacer in this application, it will be further explained and illustrated below. Figure 1 As shown, the hollow glass spacer 100 in the present application includes: a body 1 with an axis. The body 1 can be made of metal materials, such as aluminum, copper, etc. with high toughness. The body 1 can at least include a first side wall 11 and a second side wall 12 opposite to each other, and a third side wall 13 and a fourth side wall 14 opposite to each other. The first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 form a receiving cavity. When the hollow glass spacer 100 is set in the hollow glass, the first side wall 11 and the second side wall 12 are respectively close to the side surfaces of the adjacent glass in the hollow glass.

[0040] like Figure 1 As shown, the first side wall 11 and the second side wall 12 can be planar, so that they can better fit with the side of the adjacent glass in the insulating glass, thereby forming a sealed state. The third side wall 13 and the fourth side wall 14 can be planar, or slightly curved, or wavy, etc. The third side wall 13 and the fourth side wall 14 only need to be slightly curved, and there is no limitation on them in the present application.

[0041] like Figure 1As shown, the upper ends of the first side wall 11 and the second side wall 12 are connected to the third side wall 13, and the lower ends of the first side wall 11 and the second side wall 12 are connected to the third side wall 13, thereby forming a receiving cavity.

[0042] As a feasible method, the first side wall 11 and the third side wall 13 may have a first bent portion 17 that is recessed toward the accommodating cavity, that is, the corner of the body 1 may have a first bent portion 17 that is recessed toward the accommodating cavity, and the existence of the first bent portion 17 may effectively improve the strength of the entire body 1. The first bent portion 17 may include a first folded edge and a second folded edge, the first folded edge may be parallel to the fourth side wall 14, and the first folded edge is connected to the upper end of the first side wall 11. The second folded edge has a certain angle with the first side wall 11, and the second folded edge is respectively connected to the first folded edge and the third side wall 13.

[0043] As feasible, Figure 1 As shown, the second side wall 12 and the third side wall 13 may have a second bent portion 18 that is recessed toward the accommodating cavity at their connection, that is, the second bent portion 18 that is recessed toward the accommodating cavity may be provided at the corner of the body 1, and the existence of the second bent portion 18 may effectively improve the strength of the entire body 1. The second bent portion 18 may include a third folded edge and a fourth folded edge, the third folded edge may be parallel to the fourth side wall 14, and the third folded edge is connected to the upper end of the second side wall 12. The fourth folded edge has a certain angle with the second side wall 12, and the fourth folded edge is connected to the third folded edge and the third side wall 13, respectively.

[0044] like Figure 1 As shown, the structure of the non-end portion of the entire body 1 can be the same as the cross-section of a conventional spacer bar at present. Therefore, the insulating glass spacer bar 100 in the present application can be directly processed from a conventional spacer bar at present.

[0045] like Figure 1As shown, at at least one end of the body 1, the third side wall 13 and the fourth side wall 14 are pressed in a direction perpendicular to the third side wall 13 to form a sheet structure 15. In the above structure, the third side wall 13 and the fourth side wall 14 can be pressed to form the sheet structure 15 by mechanical extrusion. For example, the third side wall 13 can be tilted and extruded toward the fourth side wall 14, and the fourth side wall 14 basically does not move, and finally the third side wall 13 and the fourth side wall 14 are attached together to form the sheet structure 15; the third side wall 13 can also be tilted and extruded toward the fourth side wall 14, and the fourth side wall 14 is also tilted and extruded toward the third side wall 13, so that the position where the third side wall 13 is attached to the fourth side wall 14 to form the sheet structure 15 is lower than the height of the third side wall 13 at the non-end, and higher than the height of the fourth side wall 14 at the non-end, so that there is no need to adjust the position of the sheet structure 15 in the height direction later to ensure the flatness of the side wall when inserting other spacers. As a feasible method, the position where the third side wall 13 is attached to the fourth side wall 14 to form a sheet structure 15 is much lower than the height of the third side wall 13 at the non-end portion, and slightly higher than the height of the fourth side wall 14 at the non-end portion. This facilitates the later winding of the sheet structure 15, and other spacer strips can be inserted after it is wound into a curved shape.

[0046] In the process of forming the sheet structure 15, the first side wall 11 is bent outward along its center line so that the inner wall of the portion below the center line of the first side wall 11 is closely attached to the inner wall of the portion above the center line of the first side wall 11; the second side wall 12 is bent outward along its center line so that the inner wall of the portion below the center line of the second side wall 12 is closely attached to the inner wall of the portion above the center line of the second side wall 12. Through the above, the first side wall 11 and the second side wall 12 can be pressed into the sheet structure 15 together, and at the same time, the thickness of the sheet structure 15 will not be increased, which is conducive to the two ends of the sheet structure 15 being able to be rolled around the axis into a curved shape in the later stage. Of course, since the first side wall 11 and the second side wall 12 are bent accordingly, the width of the sheet structure 15 will be further increased, but the two ends of the sheet structure 15 located in the direction of the first side wall 11 and the second side wall 12 are rolled around the axis into a curved shape respectively, which can reduce the width of the sheet structure 15, so that the sheet structure 15 can be inserted into other spacers.

[0047] As a feasible method, the sheet structure 15 can be in a sealed state, so that one end of the body 1 with the sheet structure 15 is sealed. In a specific embodiment, the end face of the sheet structure 15 can be sealed by welding, that is, the end faces of the third side wall 13 and the fourth side wall 14 are welded, the end face of the bent first side wall 11 is welded, and the end face of the bent second side wall 12 is welded, and finally the end face of the sheet structure 15 is completely sealed. In another specific embodiment, the inner side wall of the sheet structure 15 is provided with an adhesive, so that one end of the body 1 with the sheet structure 15 is sealed. When the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 are pressed into the sheet structure 15, the adhesive can bond the inner side walls of the third side wall 13 and the fourth side wall 14, the inner side wall of the bent first side wall 11, and the inner side wall of the bent second side wall 12, and finally the end face of the sheet structure 15 is completely sealed. The sealing of the end of the hollow glass spacer 100 can be achieved in the above manner. If the accommodating cavity inside the hollow glass spacer 100 is filled with a desiccant, the sealing degree of the desiccant can be ensured to prevent it from getting damp or scattering when not in use.

[0048] like Figure 1 As shown, the two ends of the sheet structure 15 located in the direction of the first side wall 11 and the second side wall 12 are respectively rolled around the axis to form a curved shape, so that the end of the insulating glass spacer 100 can be inserted into other spacers. As a feasible method, the degree to which the two ends of the sheet structure 15 located in the direction of the first side wall 11 and the second side wall 12 are respectively rolled around the axis to form a curved shape needs to meet the following conditions: if the third side wall 13 and the fourth side wall 14 are parallel at the non-end part, the maximum distance of the contour of the curved sheet structure 15 in the direction perpendicular to the third side wall 13 is less than the distance between the inner side walls of the third side wall 13 and the fourth side wall 14 of the body 1 at the non-end part; if the first side wall 11 and the second side wall 12 are parallel at the non-end part, the maximum distance of the contour of the curved sheet structure 15 in the direction perpendicular to the first side wall 11 is less than the distance between the inner side walls of the first side wall 11 and the second side wall 12 of the body 1 at the non-end part.

[0049] like Figure 1 As shown, as feasible, the body 1 has a tapered section 16 close to the sheet structure 15, and the tapered section 16 is located between the sheet structure 15 and the body 1 of normal thickness that is not compressed. At the tapered section 16, the third side wall 13 gradually tilts toward the fourth side wall 14 until the third side wall 13 abuts against the fourth side wall 14, and the abutment between the third side wall 13 and the fourth side wall 14 is in a straight line perpendicular to the third side wall 13. The body 1 of normal thickness that is not compressed is transitioned to the sheet structure 15 through the tapered section 16.

[0050] like Figure 1 As shown, as feasible, at the tapered section 16, the first side wall 11 is recessed into the accommodating cavity of the body 1 to form a first groove 111, and the first groove 111 extends along the axial direction and extends to the abutment between the third side wall 13 and the fourth side wall 14. Similarly, at the tapered section 16, the second side wall 12 is recessed into the accommodating cavity of the body 1 to form a second groove 121, and the second groove 121 extends along the axial direction and extends to the abutment between the third side wall 13 and the fourth side wall 14. Since the third side wall 13 gradually tilts toward the fourth side wall 14 until the third side wall 13 abuts against the fourth side wall 14, the thickness of the first side wall 11 and the second side wall 12 in the vertical direction also needs to be gradually reduced. When the first groove 111 and the second groove 121 are present, the first groove 111 and the second groove 121 recessed into the accommodating cavity can accommodate parts of the first side wall 11 and the second side wall 12 with reduced thickness. In this way, at the tapered section 16, the first side wall 11 and the second side wall 12 will not be excessively extended and protruded outward due to the extrusion of the third side wall 13 gradually tilting toward the fourth side wall 14, thereby avoiding the increase in the size of the main body 1 in the direction perpendicular to the first side wall 11 and being unable to be inserted into other spacer strips.

[0051] Further, such as Figure 1 As shown, the distance between the two opposite side walls of the first groove 111 gradually decreases in the direction close to the abutment of the third side wall 13 and the fourth side wall 14 until they fit together. The distance between the two opposite side walls of the second groove 121 gradually decreases in the direction close to the abutment of the third side wall 13 and the fourth side wall 14 until they fit together. The above method ensures that in the entire tapered section 16, the area from the first side wall 11 and the second side wall 12 to the sheet structure 15 will not be excessively extended and protruded outward due to the extrusion of the third side wall 13 gradually tilted toward the fourth side wall 14, and in the sheet structure 15, it is rolled around the axis at both ends located in the direction of the first side wall 11 and the second side wall 12 to form a curved shape to reduce the size in the direction perpendicular to the first side wall 11.

[0052] Due to the existence of the tapered section 16, after the insulating glass spacer 100 is inserted into other spacers, the outer wall of the tapered section 16 can be engaged with the inner wall side of the end of the other spacer, so that the two can be connected together and are not easily separated.

[0053] A spacer assembly is also proposed in the present application. Figure 2 An exploded view of a spacing component in an embodiment of the present invention, Figure 3 is a schematic diagram of the structure of the spacer assembly after assembly in an embodiment of the present invention, Figure 4 FIG. 1 is a schematic diagram of the interior of the spacer assembly after assembly in an embodiment of the present invention. Figures 2 to 4As shown, the spacing component includes any of the above-mentioned insulating glass spacing strips 100; and a connecting spacing strip 200. The end of the insulating glass spacing strip 100 having a sheet structure 15 can be inserted into the end of the connecting spacing strip 200. Furthermore, the cross-section of the connecting spacing strip 200 in the radial direction can be the same as the cross-sectional structure of the insulating glass spacing strip 100 in the non-end portion in the radial direction. In this way, when the end of the insulating glass spacing strip 100 having a sheet structure 15 is inserted into the end of the connecting spacing strip 200, each side wall of the insulating glass spacing strip 100 and each corresponding side wall of the connecting spacing strip 200 can be located on the same plane, which can not only ensure that the entire spacing component can fit with the glass after the spacing component is installed in the insulating glass to ensure sealing, but also improve the aesthetics of the spacing component. During the production process of the insulating glass spacing strip 100 in the present application, a desiccant can be first filled and then processed at the end to form a sheet structure, and no holes are opened at the side wall of the main body 1 during the production process. When the entire spacing assembly is installed in the insulating glass, a hole is opened at the side wall of the main body 1 to prevent the desiccant in the insulating glass spacing strip from being exposed to the air for a long time, which would lead to a decrease in adsorption capacity.

[0054] The present application also proposes a door, which includes any of the above-mentioned insulating glass spacers 100 . The insulating glass spacer 100 can be installed in an insulating glass, and the insulating glass is installed in the above-mentioned door.

[0055] The present application also proposes a window, which includes any of the above-mentioned insulating glass spacers 100 . The insulating glass spacer 100 can be installed in an insulating glass, and the insulating glass is installed in the above-mentioned window.

[0056] The present application also proposes a method for processing a hollow glass spacer strip, and the method for processing a hollow glass spacer strip may include the following steps:

[0057] like Figure 1 As shown, the first side wall 11 of the body 1 is pressed toward the accommodating cavity of the body 1 to form a concave first groove 111, and the second side wall 12 of the body 1 is pressed toward the accommodating cavity of the body 1 to form a concave second groove 121. The first groove 111 and the second groove 121 are located at the position of the tapered section 16, that is, the first groove 111 and the second groove 121 are still a distance away from the end surface of the end of the body 1, and the length of the distance is the length of the sheet structure 15. By processing the first groove 111 and the second groove 121 in advance, it is possible to prevent the first side wall 11 and the second side wall 12 from excessively extending and protruding outward due to the extrusion of the third side wall 13 gradually tilting toward the fourth side wall 14 in the later stage.

[0058] like Figure 1As shown, the third side wall 13 of the body 1 is pressed downward toward the fourth side wall 14, so that the third side wall 13 gradually tilts toward the fourth side wall 14, until the third side wall 13 and the fourth side wall 14 abut against each other, thereby forming a tapered section 16. In the above steps, the fourth side wall 14 can also be pressed downward toward the third side wall 13, so that the fourth side wall 14 also gradually tilts toward the third side wall 13. The degree to which the fourth side wall 14 tilts toward the third side wall 13 is much smaller than the degree to which the third side wall 13 gradually tilts toward the fourth side wall 14, so that the position where the third side wall 13 abuts against the fourth side wall 14 is lower than the height of the third side wall 13 at the non-end, and slightly higher than the height of the fourth side wall 14 at the non-end, thereby ensuring that there is enough space for winding the sheet structure 15 in the later stage, and other spacers can be inserted after winding into a curved shape.

[0059] like Figure 1 As shown, the third side wall 13 and the fourth side wall 14 at the end of the body 1 are flattened in a direction perpendicular to the third side wall 13 to form a planar sheet structure 15. In the above steps, the third side wall 13 and the fourth side wall 14 of the area near the end of the tapered section 16 are flattened in a direction perpendicular to the third side wall 13 to form a planar sheet structure 15. Before the flattening process, the first side wall 11 of the above area can be bent outward along the center line a little, so that the inner wall of the first side wall 11 below the center line is tightly attached to the inner wall of the first side wall 11 above the center line during the flattening process. Before the flattening process, the second side wall 12 can be bent outward along the center line a little, so that the inner wall of the second side wall 12 below the center line is tightly attached to the inner wall of the second side wall 12 above the center line during the flattening process.

[0060] In the above steps, if the sheet structure 15 needs to be sealed, a small amount of adhesive can be filled inside the end of the body 1 before flattening to form the sheet structure 15. After the end of the body 1 is flattened, the adhesive diffuses to seal the inside of the sheet structure 15. Alternatively, after the sheet structure 15 is formed, the end surface of the sheet structure 15 is welded to achieve a sealing effect.

[0061] like Figure 1As shown, the two ends of the sheet structure 15 in the direction of the first side wall 11 and the second side wall 12 are respectively rolled around the axis to be curved. In this step, the two ends of the sheet structure 15 in the direction of the first side wall 11 and the second side wall 12 can be clamped by mechanical automation equipment and rolled toward the axis of the body 1, so that the two ends of the sheet structure 15 are curved. In this way, the maximum distance of the contour of the curved sheet structure 15 in the direction perpendicular to the first side wall 11 can be smaller than the distance between the inner side walls of the first side wall 11 and the second side wall 12 of the body 1 at the non-end, and the maximum distance of the contour of the curved sheet structure 15 in the direction perpendicular to the third side wall 13 can be smaller than the distance between the inner side walls of the third side wall 13 and the fourth side wall 14 of the body 1 at the non-end. Finally, the end of the insulating glass spacer 100 can be inserted into other spacers.

[0062] In the present application, ordinary conventional spacers without sheet structures 15 and tapered sections 16 are processed into insulating glass spacers 100. The entire process only requires mechanical extrusion without other processing methods. The processing process is simple, environmentally friendly and neat. The insulating glass spacers 100 can be completed completely through automated processing, which greatly improves processing efficiency and reduces production costs.

[0063] In addition, the insulating glass spacer 100 in the present application can be directly connected with the connecting spacer 200, that is, the spacer without the sheet structure 15 and the tapered section 16, by plugging together to form a spacer assembly in the insulating glass, which can directly form a closed ring to keep the gas in the insulating glass dry. The entire spacer assembly avoids the use of plug-in parts and uses only spacers, which reduces labor costs and damage to auxiliary materials, and greatly saves costs.
