Description

Technical Field

[0001] The utility model belongs to the technical field of window frame corner assembly pieces, and in particular relates to a corner assembly piece. Background Art

[0002] The function of the corner piece is to enhance the strength of the corner piece and to make it smooth. However, after being installed in the window frame, the ordinary corner piece may not fit the inner wall of the window frame, resulting in a loose connection. At the same time, the ordinary openings on the corner piece are not easy to align with the glue gun nozzle, or the glue gun nozzle is easy to slip after being inserted into the opening, making it impossible to accurately inject glue into the window frame.

[0003] To this end, a conveniently installed assembled angle piece with announcement number "CN219365855U" is disclosed, wherein a top bending head is provided on the top of the assembled angle steel piece, and the top bending head is formed by bending the top of the assembled angle steel piece downward, a circular groove is provided on the top of the assembled angle steel piece near the top bending head, and a glue injection hole is provided in the middle of the circular groove, and glue is injected and bonded to the window frame through the glue injection hole. Since the top bending head is formed by bending the top of the assembled angle steel piece downward, after the two sets of window frame strips are tightly connected, the top bending head is also close to the inner wall of the window frame strip, so that the assembled angle steel piece is more fitted, flush and firm when installed; finally, glue is injected into the window frame strip through the glue injection hole, so that the window frame strips are tightly connected together to form a window frame, and the glue injection can also play a sealing and waterproof role; through the setting of the circular groove, the glue gun nozzle can be accurately inserted into the glue injection hole, and when gluing, the glue gun nozzle is not easy to slip out of the glue injection hole.

[0004] However, for the above-mentioned easy-to-install corner assembly, although the glue injection hole is set in the middle of the circular groove, the setting of the circular groove allows the glue gun nozzle to be accurately inserted into the glue injection hole, and the glue gun nozzle is not easy to slip out of the glue injection hole when applying glue, but there are still the following obvious defects during use: the corner assembly is inserted and fitted into the slot on the inner side of the window frame to assemble the window frame, and when injecting glue through the glue injection hole to the fitting surface with the inner wall of the window frame, the injected glue cannot overflow and the adhesive cannot completely cover the corner assembly and fit the window frame, which easily causes the corner assembly to loosen and separate after being combined with the window frame. Utility Model Content

[0005] The purpose of the utility model is to provide a corner assembly piece to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled angle piece, comprising an assembled angle steel piece for inserting into the corner of a window frame and being at a right angle, one side of the assembled angle steel piece being attached to the inner wall of the window frame and the other side being provided with a flat convex portion that is a V-shaped stamping convex outward, the assembled angle steel piece being provided with an upwardly protruding blocking convex edge on one side of the flat convex portion, and the inner side of the blocking convex edge and one side of the assembled angle steel piece forming a bonding and injection concave surface;

[0007] The surfaces of both wings of one side of the angle steel sheet are provided with reinforcing protrusions that are stamped outwards, and the reinforcing protrusions are away from the surface and are located on the other side of the angle steel sheet and are stamped with strip grooves.

[0008] Preferably, a glue injection hole is punched through the surface of the outer right angle of the angle steel sheet, and the glue injection hole allows the angle steel sheet to be combined with the inner slot of the window frame and then the adhesive glue can be injected into the side of the angle steel sheet that fits against the inner wall of the window frame.

[0009] Preferably, the outer corner side of the angle steel sheet is provided with a top bending portion, and after the two sets of window frame strips are tightly connected, the top bending head is also closely attached to the inner wall of the window frame strip.

[0010] Preferably, a glue injection guide channel is formed between the adhesive glue injection concave surface and the reinforcing raised strips arranged on both wings of one side of the assembled angle steel sheet, so that after the adhesive is injected into the bonding surface, the adhesive can be completely bonded to the bonding surface through the glue injection guide channel.

[0011] Preferably, an auxiliary butt joint semicircular groove is provided at the inner corner of the angle steel sheet for tightly fitting the two wings of the angle steel sheet with the window frame, so that after the two window frames are combined by the angle steel sheet, the combined gap can fit more perfectly.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the assembled angle piece, through the design of the bonding injection concave surface formed by the blocking raised edge on one side of the assembled angle steel piece, and the bonding injection concave surface and the reinforcing raised strip formed by the design of the injection guide channel, after the assembled angle steel piece and the window frame are inserted and combined, the adhesive is injected into the bonding injection concave surface through the injection hole, and the injected adhesive flows through the injection guide channel to the side that fits the inner wall of the window frame, so that the assembled angle piece can be more firmly attached to the inner wall of the combined window frame corner, and then the window frame can be more firmly assembled by the assembled angle steel piece, so that the problem of window frame detachment due to reduced viscosity caused by the small adhesive surface will not occur.

[0013] By designing a side of the angle steel sheet that fits the inner wall of the window frame to block the raised edge, it can be ensured that the adhesive injected into the adhesive injection concave surface will not overflow into the inner groove of the window frame during the glue injection process through the glue injection hole. The injected adhesive can be completely bonded to the inner wall of the window frame to maintain good bonding firmness, thereby making the combined installation of the window frame more beautiful and in line with design requirements, and can better support and connect the profiles, thereby enhancing the strength and stability of the joints.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a corner assembly piece, comprising a right-angled angle steel piece 1 for inserting into the corner of a window frame, one side of the angle steel piece 1 is attached to the inner wall of the window frame, and the other side is provided with a V-shaped stamped outwardly convex leveling protrusion 2, the outwardly convex side of the leveling protrusion 2 is attached to the inner wall of the window frame, and when the angle steel piece 1 is assembled and installed with the window frame, it has a leveling effect, and the angle steel piece 1 is provided with an upwardly convex blocking protrusion edge 3 on one side of the flattening protrusion 2 The blocking raised edge 3 can make the glue injected into one side of the assembled angle steel sheet 1 more full, thereby strengthening the firmness and stability of the assembly of the assembled angle steel sheet 1 and the window frame. The blocking raised edge 3 is formed by punching the flat assembled angle steel sheet 1 through a stamping and bending edge mold. The inner side of the blocking raised edge 3 and one side of the assembled angle steel sheet 1 form a bonding and injection concave surface 4, so that the adhesive injected into one side of the inner wall of the window frame is covered on the entire bonding surface, so that the window frame becomes more firm after the assembled angle is assembled using the assembled angle steel sheet 1.

[0020] The surfaces of both wings of one side of the assembled angle steel sheet 1 are provided with reinforcing protruding strips 5 which are stamped outward, and the side away from the reinforcing protruding strips 5 is a strip-shaped concave groove, which is conducive to the removal of the assembled angle steel sheet and can also enhance the overall hardness of the assembled angle steel sheet 1, making the window frame more stable and firm after the angle is assembled. The reinforcing protruding strip 5 is away from the surface and is located on the other side of the assembled angle steel sheet 1. There is a strip-shaped groove 6 stamped and formed, which is conducive to the removal of the assembled angle steel sheet 1 and the separation of the window frame with a sharp tool when the assembled angle steel sheet is difficult to remove from the inner wall of the window frame.

[0021] The surface of the outer right angle of the group of angle steel sheets 1 is punched with a glue injection hole 7, which is on the same horizontal plane as the right-angle steel sheet, and the port of the glue injection hole 7 on one side for glue injection extends outward and is provided with an arc-shaped concave surface, which is conducive to the glue injection tool to be accurately inserted into the glue injection hole 7 and inject adhesive glue into the adhesive glue injection concave surface 4.

[0022] The outer corner side of the group angle steel sheet 1 is provided with a top bending portion 8, and the top bending portion 8 is formed by bending the top of the group angle steel sheet 1 downward. After the two groups of window frame strips are tightly connected, the top bending portion 8 is also close to the inner wall of the window frame strip, so that the group angle steel sheet 1 is more fitted, flush and firm during installation.

[0023] A glue injection guide channel 9 is formed between the adhesive glue injection concave surface 4 and the reinforcing raised strips 5 arranged on both wings of one side of the assembled angle steel sheet 1, so that the adhesive glue is injected into the glue injection through hole 7 and then flows through the glue injection guide channel 9 to adhere to one side of the inner wall of the window frame, making the injected glue fuller and having better adhesion.

[0024] The inner corner of the angle steel sheet 1 is provided with an auxiliary docking semicircular groove 10 for tightly fitting the two wings of the angle steel sheet 1 with the window frame, so that after the window frame is assembled, the inner corner and the outer corner of the window frame are tightly combined to ensure a more perfect window frame assembly.

[0025] Specifically, when in use, one side of the assembled angle steel sheet 1 is inserted into the window frame strip. Due to the leveling protrusions 2, blocking protrusion edges 3 and reinforcing protrusion strips 5 formed on the upper surfaces of the two wings of the assembled angle steel sheet 1, the leveling protrusions 2, blocking protrusion edges 3 and reinforcing protrusion strips 5 are stuck in the corresponding grooves on the side wall of a window frame strip. Then, another window frame strip is docked with the window frame strip, so that the two sides of the assembled angle steel sheet 1 are respectively inserted into the corresponding window frame strips; then the two window frame strips are pressed together, so that the two sets of window frame strips are tightly connected together. At the same time, since the top bending portion 8 is formed by bending the top of the assembled angle steel sheet 1 downward, after the two window frame strips are tightly connected, the top bending portion 8 is also close to the window The inner wall of the frame strip makes the assembled angle steel sheet 1 fit better during installation, and finally glue is injected into the inner wall of the window frame strip and the assembled angle steel sheet 1 through the glue injection through hole 7, and in the process of injecting glue, the glue enters the inside of the bonding glue injection concave surface 4, and the glue flows through the glue injection guide channel 9 formed between the bonding glue injection concave surface 4 and the reinforcing raised strip 5 to the entire side of the assembled angle steel sheet 1 that fits the inner wall of the window frame, so that the assembled angle steel sheet 1 can be more firmly bonded to the inner groove of the window frame, so that the window frame strips are closely connected together to form a more firm and stable window frame, and there will be no phenomenon of glue overflowing into the inner groove of the window frame, further improving the firmness and integrity of the combination of the assembled angle piece and the window frame strip.
