Description

Technical Field

[0001] The invention relates to the field of processing and manufacturing aluminum alloy thermal insulation doors and windows, and in particular to a glue injection angle code capable of generating three glue rings for a special-shaped cavity. Background Art

[0002] In order to achieve a firm connection between the horizontal and vertical frames of the aluminum alloy thermal break doors and windows on the building, special angle brackets are needed for assembly to achieve the angle combination and reinforcement. Subsequently, the angle brackets are injected with glue through the injection holes on the surface of the aluminum profile cavity to improve the strength and sealing of the product. At present, the injection process of the angle brackets for doors and windows is still the most popular and advanced practical technology, but due to the following defects of traditional angle brackets, it is difficult to truly play its due role.

[0003] 1. The traditional glue injection corner code has two arms with rectangular cross-sections, which can only be used for profile cavities with rectangular cross-sections. It can barely be used for profiles with irregular shaped cavities (such as L-shaped, stepped, polygonal, etc.) on the outside of current window and door leaves, but it will produce cavities next to the corner code, and glue will inevitably leak during glue injection, which will directly affect the strength and sealing of the door and window corners. At the same time, it largely restricts the high-quality and diversified design of the aluminum profile cross-section structure, and creates certain technical bottlenecks for the upgrading of high-quality aluminum alloy insulation doors and windows.

[0004] 2. The traditional guide plate type glue injection corner code (reference announcement number CN 207092872 U and mass production examples) requires the use of a guide plate (usually made of PA66 or PVC) to guide the corner code for glue injection. While it has the above-mentioned defects, the guide plate is inserted into the aluminum profile cavity together with the corner code, and there is a "flexible contact" between the two without glue, and it is also impossible to achieve direct and effective bonding between the corner code and the inner wall of the corresponding profile. Therefore, it has little effect on improving the strength and sealing performance of the corners of doors and windows.

[0005] 3. The one-piece and split glue-injected corner brackets (reference application number 201821058547.7, application number 201720625303.1, application number 201520856633.2, application number 201420111075.2 and similar production examples) disclosed by inventions or utility models in recent years, after glue injection, generally only one surface or at most three surfaces of the four surfaces of the two arms can achieve adhesion with the inner wall of the corresponding profile, and the "arm annular tape" cannot be achieved at all. In addition, in view of the poor fluidity of the corner glue, the existing corner bracket glue channel design is unreasonable, and the corner glue can only be introduced into the profile cavity for a short distance. Some are even limited to theoretical design. In actual glue injection construction, it is impossible to achieve that the glue is delivered to the far end according to the established glue channel. In addition, the existing corner brackets have varying degrees of problems such as unreasonable manufacturing processes that make mass production difficult, high finished product costs, complex profile corner bracket assembly processes, poor positioning of doors and windows after corner assembly and before glue injection, and easy deformation of right angles. These problems have affected the real improvement of the strength and sealing of the corners of aluminum alloy insulated doors and windows, and also limited the widespread application and further promotion of glue-injected corner brackets. Summary of the invention

[0006] The purpose of the present invention is to provide a glue injection angle code for generating three glue rings for a special-shaped cavity, which can solve the above-mentioned problem.

The glue guide holes located in the corner annular glue groove include the corner main glue hole and the corner auxiliary glue guide hole, and the glue guide holes located in the support arm annular glue groove include the support arm main glue hole and the support arm auxiliary glue guide hole. The corresponding main glue holes and auxiliary glue guide holes are cross-shaped and respectively pass through the corner annular glue groove and the support arm annular glue groove.

[0014] The above-mentioned glue injection angle code for special-shaped cavities can generate three glue rings. The support arm is provided with a special-shaped portion of the angle code, which can be used for profile cavities with special-shaped cross-sections such as rectangular, L-shaped, stepped, and polygonal shapes.

[0015] The above-mentioned glue injection angle code for a special-shaped cavity that can generate three glue rings, the support arm is also provided with a first corner group cutting surface and a second corner group cutting surface, both of which are located on the outer side surface of the support arm of the angle code body, have the same shape, and have the same angle as the support arms, wherein the first corner group cutting surface is adjacent to the annular glue groove of the support arm.

[0016] The beneficial effect of the present invention is that the present invention can generate three glue rings for the glue injection angle code of the special-shaped cavity, and the special-shaped part of the angle code is arranged on the support arm, which can be used for the profile cavity with rectangular, L-shaped, stepped, polygonal and other special-shaped cross-sections, which solves the technical bottleneck of aluminum profile design.

It can fully realize the direct and effective bonding of each surface of the angle code body with the corresponding profile inner wall, and form three annular tapes, so that the strength, rigidity and sealing of the corners of doors and windows are greatly improved, and the service life of doors and windows is effectively increased.

[0025] The present invention is further described below in conjunction with specific embodiments, wherein the accompanying drawings are only used for exemplary descriptions and represent only schematic diagrams rather than actual drawings, and should not be understood as limitations on this patent. In order to better illustrate the specific embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, a glue injection corner code for generating three glue rings for a special-shaped cavity is L-shaped as a whole, and includes two support arms 14 with the same structure. A circle of continuous corner annular glue grooves 7 is provided along the edge of the 45° inclined section at the junction of the two support arms 14. A circle of continuous support arm annular glue grooves 8 is provided on the support arm 14. The corner annular glue grooves 7 and the support arm annular glue grooves 8 are both provided with glue guide holes 15, and are connected to each other through the support arm main glue channel 3 and the inner ring connecting glue channel 9. The support arm 14 is provided with a special-shaped corner code portion 11, which can be used for profile cavities with rectangular, L-shaped, stepped, polygonal and other special-shaped cross-sectional shapes.

[0027] After the corners are assembled in a conventional manner using the glue injection corner code that can generate three glue rings for a special-shaped cavity, the corner assembly glue is injected into the corner code portion through the glue injection holes on the surface of the aluminum profile cavity. The corner assembly glue is injected in multiple parallel paths along the glue path, relaying and complementing each other to cover all the glue paths and form three annular adhesive tapes.

[0028] When injecting glue, the corner glue is continuously injected into the glue injection source area 1, and the corner glue is simultaneously supplied to the corner main glue hole 2, the support arm main glue channel 3, and the glue grooves on both sides of the corner main glue hole 2 on the corner annular glue groove 7, and gradually fills the glue groove. After the corner glue that enters the corner main glue hole 2 reaches the cross-intersection position of the corner main glue hole 2 and the corner secondary glue guide hole 5, it is divided into three glue paths. One path of the corner glue continues along the corner main glue hole 2 to the glue groove on the opposite side of the corner annular glue groove 7. After filling the glue groove, it gradually supplies glue to the inner inter-ring connecting glue channel 9 and the glue grooves on both sides of the corner annular glue groove 7. The two paths of the corner glue are respectively along the corner secondary glue guide hole 5 to the glue grooves on both sides of the corner annular glue groove 7, and gradually fill the glue groove. The corner glue that enters the main glue channel 3 of the support arm is supplied along the main glue channel 3 to the main glue hole 4 of the support arm and the glue grooves on both sides of the main glue hole 4 of the support arm on the annular glue groove 8 of the support arm, and gradually fills the glue groove. After the corner glue that enters the main glue hole 4 of the support arm reaches the cross position of the main glue hole 4 of the support arm and the auxiliary glue guide hole 6 of the support arm, it is divided into three glue paths. One path of corner glue continues along the main glue hole 4 of the support arm to reach the glue groove on the opposite side of the annular glue groove 8 of the support arm. After filling the glue groove, it gradually supplies glue to the glue channel 9 connecting the inner ring and the glue grooves on both sides of the annular glue groove 8 of the support arm. The two paths of corner glue are respectively supplied along the auxiliary glue guide hole 6 of the support arm to the two sides of the annular glue groove 8 of the support arm, and gradually fill the glue groove. Finally, the corner glue is connected along the shortest path, through mutual relay and complementation, to achieve the full glue injection effect of the three rings of the corner annular glue groove 7 and the two annular glue grooves 8 of the support arm.

[0029] The support arm 14 is provided with a corner code shaped portion 11, which can be used for profile cavities with rectangular, L-shaped, stepped, polygonal and other shaped cross-sectional shapes. In particular, it has excellent adaptability to profiles with shaped cavities on the outer sides of current window sashes and door sashes, and can achieve a tight combination of the corner code body 10 and the aluminum profile cavity. Coupled with the bonding of the corner assembly glue, high strength, high rigidity and high sealing of the door and window corners can be achieved.

[0030] The support arm 14 is also provided with a first corner tying knife cut surface 12 and a second corner tying knife cut surface 13, both of which are located on the outer side surfaces of the support arms 14 of the corner code body 10, have the same shape, and have the same angle as the support arms 14, which can further reinforce the corner code and profile and enhance the strength of the corner tying.

[0031] Although specific embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
