Abstract
Description
Technical Field
[0001] This utility model relates to the field of window accessories technology, and in particular to a window glass load-bearing pad. Background Technology
[0002] Currently, most glass spacers on the market are made of plastic. Due to the limited space between the glass and the frame, the thickness of the spacers cannot be increased. This leads to problems with the load-bearing capacity of extra-large windows and curtain wall glass. The spacers may deform or crack because they cannot support the weight of the glass, which can easily cause the glass to break or shake, or even threaten the personal safety of the residents.
[0003] Therefore, improvements are needed. Utility Model Content
[0004] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a window glass load-bearing pad to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a window glass load-bearing pad, comprising: an aluminum pad, the aluminum pad including a horizontal part, a first protrusion and a second protrusion, the first protrusion and the second protrusion being respectively disposed on both sides of the horizontal part; and a plastic layer, the plastic layer being wrapped around the aluminum pad.
[0006] Furthermore, the connection between the first protrusion and the horizontal part is a circular arc transition.
[0007] Furthermore, the connection between the second protrusion and the horizontal part is a circular arc transition.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] Enhanced load-bearing capacity: The aluminum pads have high strength and rigidity, which can effectively support the weight of extra-large windows and curtain wall glass, avoiding deformation or breakage of the pads due to insufficient load-bearing capacity, thereby improving the stability and safety of window glass.
[0010] Reduce stress concentration: The connection between the first and second protrusions and the horizontal part adopts a rounded transition design, which effectively disperses the stress at the contact point between the glass and the pad, reduces the risk of glass breakage, and extends the service life of the pad.
[0011] Improved durability: The plastic layer wrapped around the aluminum pad not only protects the aluminum pad but also enhances its corrosion resistance and wear resistance, making it suitable for various complex environments and extending the service life of the pad. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0018] In view of the technical problems described in the background art, such as Figure 1-3 As shown, a window glass load-bearing pad is provided, including: an aluminum pad 1, the aluminum pad 1 including a horizontal part 2, a first protrusion 3 and a second protrusion 4, the first protrusion 3 and the second protrusion 4 respectively disposed on both sides of the horizontal part 2; and a plastic layer 5, the plastic layer 5 wrapping the aluminum pad 1.
[0019] In the above technical solution, the aluminum pad 1 is made of high-strength aluminum alloy material, which has good rigidity, compressive strength and corrosion resistance, and can bear the weight of ultra-large windows and curtain wall glass; the plastic layer 5 is made of engineering plastics (such as PVC, nylon or polyurethane) with excellent weather resistance, wear resistance and heat insulation performance, to ensure the long-term stability of the pad in complex environments.
[0020] In this invention, the core of the traditional plastic spacer is replaced with an aluminum spacer 1, and a plastic layer 5 is wrapped around the aluminum spacer 1 to protect the glass. This solves the problem of load-bearing capacity for ultra-large windows and curtain wall glass, effectively supporting the weight of ultra-large windows and curtain wall glass and preventing deformation or breakage of the spacer due to insufficient load-bearing capacity, thereby improving the stability and safety of the window glass. At the same time, the plastic layer 5 wrapped around the aluminum spacer 1 not only protects the aluminum spacer 1, but also enhances the spacer's corrosion resistance and wear resistance, making it suitable for various complex environments and extending the spacer's service life.
[0021] The connection between the first protrusion 3 and the horizontal portion 2 is a rounded transition. The connection between the second protrusion 4 and the horizontal portion 2 is also a rounded transition.
[0022] Furthermore, the connection between the first protrusion 3 and the second protrusion 4 and the horizontal part 2 adopts an arc transition design, which effectively disperses the stress at the contact point between the glass and the pad, reduces the risk of glass breakage, and extends the service life of the pad.
[0023] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
