This greatly enhances the airtightness and watertightness of the corner. At the same time, the protruding ridges in the injection groove engage with the bottom of the sealant strip, and the barbed ridges lock with the top of the sealant strip, forming a double mechanical anchoring structure. Combined with the "I"-shaped sealant structure, the sealant strip and the profile body are integrated into a whole, with extremely strong pull-out resistance, effectively preventing the sealant strip from loosening or falling off during long-term use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building door and window profile technology, and in particular to a high weather-resistant American-style profile. Background Technology
[0002] American-style window and door profiles are popular in the market due to their heavy lines and classic style. To improve their thermal insulation performance, the technology of injecting heat insulation glue into the cavity of the profile is generally adopted. The corners of the profile are usually cut at a 45° angle and spliced, and the V-shaped opening at the splice is filled with sealant for sealing.
[0003] However, when splicing the corners of existing profiles, the sealant is only applied to the surface of the V-shaped opening, forming a thin surface adhesive layer. When the profiles expand and contract due to temperature differences between day and night or seasons, the corners become stress concentration points, causing the fragile adhesive layer to be repeatedly stretched and compressed. Over time, cracks and delamination will occur. Once cracked, rainwater and air will seep in along the gaps, affecting the thermal insulation and waterproofing performance of doors and windows.
[0004] Therefore, we propose a high weather-resistant American-style profile to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a high weather-resistant American-style profile to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high weather-resistant American-style profile includes a profile body and a rubber strip. The profile body is provided with a glue injection groove, and molten glue is injected into the glue injection groove and cooled to form a rubber strip. A broken bridge opening is provided at the bottom of the glue injection groove. Intersecting longitudinal guide grooves and transverse guide grooves are provided on the oblique cut surface of the rubber strip, and glue injection ports penetrating the outer surface of the rubber strip are provided at both ends of the longitudinal guide grooves.
[0008] In a further embodiment, the bottom of the glue injection groove is symmetrically provided with a pair of upwardly protruding ridges, and the inner edges of the two symmetrical sides of the upper port of the glue injection groove are provided with downwardly protruding barb ridges.
[0009] In a further embodiment, the protruding surfaces of both the convex ridge and the barbed ridge are arc-shaped.
[0010] In a further embodiment, the width of the injection port is smaller than the width of the bottom of the port, so as to form a trapezoidal or dovetail-shaped structure.
[0011] In a further embodiment, the longitudinal guide groove and the two injection ports form an "I" shaped structure.
[0012] In a further embodiment, the depth of the longitudinal and transverse guide channels is 0.5-2 mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention provides a clear flow path for the sealant through a pre-set guide groove and injection port, allowing the sealant to quickly fill the corner and form a "three-dimensional sealing net" covering the entire mating surface. This greatly enhances the airtightness and watertightness of the corner. At the same time, the protruding ridges in the injection groove engage with the bottom of the sealant strip, and the barbed ridges lock with the top of the sealant strip, forming a double mechanical anchoring structure. Combined with the "I"-shaped sealant structure, the sealant strip and the profile body are integrated into a whole, with extremely strong pull-out resistance, effectively preventing the sealant strip from loosening or falling off during long-term use.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 A high weather-resistant American-style profile, wherein the profile body 1 is made of aluminum alloy material extrusion molding, and an injection groove 2 is integrally formed on the profile body 1. Two upward-protruding arc-shaped ridges 22 are symmetrically formed on the inner bottom of the injection groove 2, and two downward-protruding arc-shaped barb ridges 23 are symmetrically formed on the inner edge of the upper port of the injection groove 2. Molten PVC or other polymer materials are injected into the injection groove 2 through injection molding process. After cooling, a rubber strip 3 is formed that is closely fitted with the shape of the injection groove 2. After the rubber strip 3 is formed, a thermal break 21 is cut out at the bottom of the injection groove 2.
[0025] The profile with the adhesive strip 3 is cut to the required length, with the ends cut at a 45-degree bevel. During the cutting process, longitudinal guide grooves 32 and transverse guide grooves 33 are milled on the exposed beveled surface of the adhesive strip 3 along the length of the profile using a special tool. The groove depth is controlled between 0.5-2mm, forming a cross-shaped or grid-shaped structure. At the same time, at both ends of the beveled surface, i.e., the inner and outer sides of the corners, corresponding to the ends of each longitudinal guide groove 32, an injection port 31 connecting the longitudinal guide grooves 32 is milled. The injection port 31 is preferably processed into a trapezoidal or dovetail shape. After the sealant is filled and cured, the sealant cannot be directly pulled out, forming a strong mechanical locking force to prevent the sealant from falling off due to aging or stress.
[0026] The 45-degree beveled surfaces of the two processed profiles are joined together and mechanically fixed using corner brackets. At this time, the guide groove network and the injection port 31 on the two adhesive strips 3 are also precisely aligned. Using a special glue gun, the sealant is injected from the aligned injection port 31 on the inside of the corner. Under pressure, the sealant quickly enters the network channel composed of the longitudinal guide groove 32 and the transverse guide groove 33 through the injection port 31. The sealant first fills the longitudinal guide groove 32, and then spreads to the surrounding area through the transverse guide groove 33. Finally, it quickly and evenly fills the entire beveled mesh system and slightly overflows from the injection port 31 on the outside of the corner. After the sealant cures, a three-dimensional sealing structure is formed between the mating surfaces of the two profiles.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
