Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a self-leveling glue-injecting corner piece. Background Technology

[0002] Corner brackets are accessories used to strengthen the connection points of doors and windows, ensuring smooth and even joints, and making doors and windows more robust and durable. By inserting and securing corner brackets at the joints of door and window frames, the stability and load-bearing capacity of doors and windows can be effectively increased. However, even after assembling existing corner brackets with the corner joints of door and window frames, a certain gap may still exist. This can lead to insufficient tightness at the joints, resulting in risks such as loosening and slight misalignment at the door and window frame connections. Utility Model Content

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a self-leveling glue-injecting corner piece. When the corner piece body is combined with the door and window, it can automatically level itself by setting two rows of protrusions on the glue-injecting surface of the corner piece body and make the corner piece body fit tightly with the door and window, thereby making the glue application of the corner piece body more uniform and preventing loosening or misalignment at the connection between the corner piece body and the door and window.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A self-leveling, glue-injecting corner piece includes a corner piece body, which comprises an integrally formed first corner piece and a second corner piece, the first corner piece and the second corner piece being perpendicularly connected to each other; one side of the corner piece body is a bonding surface, and the other side of the corner piece body is a glue-injecting surface, the glue-injecting surface having a groove formed by a recess at the connection between the first corner piece and the second corner piece, a glue-injecting hole being provided through the groove through the corner piece body, a row of first protrusions being provided near the first corner piece of the groove, the first protrusions being inclined toward the first corner piece to form a first slope, and a row of second protrusions being provided near the second corner piece of the groove, the second protrusions being inclined toward the second corner piece to form a second slope; the surfaces of the first protrusions and the surfaces of the second protrusions are located on the same plane and are both higher than the glue-injecting surface.

[0006] In one embodiment, the center line of the connection between the first corner piece and the second corner piece is a right-angled diagonal, and the adhesive groove passes through the connection between the first corner piece and the second corner piece along the direction of the right-angled diagonal.

[0007] In one implementation, a row of first protrusions and a row of second protrusions are symmetrically arranged relative to the right-angle diagonal.

[0008] In one embodiment, the end of the first corner piece away from the second corner piece is provided with a first insertion end, and the end of the second corner piece away from the first corner piece is provided with a second insertion end.

[0009] In one embodiment, the first inclined surface of each first protrusion is inclined toward the first insertion end, and the first inclined surface is connected to the first corner piece; the second inclined surface of each second protrusion is inclined toward the second insertion end, and the second inclined surface is connected to the second corner piece.

[0010] In one embodiment, the number of the first protrusions is two or more, and the number of the second protrusions is two or more.

[0011] As one implementation, a groove is provided on the connecting surface.

[0012] As one implementation method, the corner piece is made of plastic.

[0013] In one embodiment, the injection hole is a round hole.

[0014] Compared with traditional technologies, the beneficial effects of the self-leveling glue-injecting corner piece of this utility model are:

[0015] When assembling the self-leveling glue-injecting corner piece of this utility model embodiment with the door and window frame, the corner piece body is inserted into the door and window frame through the mutually perpendicular first and second corner pieces. During the insertion process, when the first and second protrusions are about to contact the inner wall of the door and window frame, the row of first protrusions near the first insertion end uses their respective first inclined surfaces to allow the row of first protrusions to be smoothly inserted into the door and window frame. Similarly, the row of second protrusions near the second insertion end also uses their respective second inclined surfaces to be inserted into the door and window frame. In this way, the corner piece body abuts against the inner wall of the door and window frame through the two rows of protrusions, and the deformation properties of the two rows of protrusions make the corner piece body abut against the inner wall of the door and window frame, so that the corner piece body will not be misaligned or loose, and the glue application during the glue injection of the corner piece body is more uniform. In other words, the self-leveling glued corner piece according to the embodiment of this utility model can not only automatically level and fix, but also make the connection between the corner piece body and the door and window frame more stable and firm.

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", 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 are not intended to 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 understood as a limitation on this utility model.

[0031] Please see Figures 1 to 10 This embodiment provides a self-leveling, glue-injecting corner piece, including a corner piece body 10. The corner piece body 10 includes an integrally formed first corner piece 20 and a second corner piece 30, which are perpendicularly connected to each other. One side of the corner piece body 10 is a bonding surface 11, and the other side is a glue-injecting surface 12. The glue-injecting surface 12 has a recessed glue channel 13 at the connection between the first corner piece 20 and the second corner piece 30, through which the corner piece 30 is inserted. The main body 10 is provided with a glue injection hole 14. The glue channel 13 is provided with a row of first protrusions 40 near the first corner piece 20. The first protrusions 40 are inclined towards the first corner piece 20 to form a first inclined surface 41. The glue channel 13 is provided with a row of second protrusions 50 near the second corner piece 30. The second protrusions 50 are inclined towards the second corner piece 30 to form a second inclined surface 51. The surfaces of the first protrusions 40 and the second protrusions 50 are located on the same plane and are both higher than the glue injection surface 12.

[0032] The corner piece body 10 is made of plastic, and the first protrusion 40 and the second protrusion 50 are also made of plastic and have a certain deformation capability. In this way, when the corner piece body 10 is assembled with the door and window frame, the first protrusion 40 and the second protrusion 50 can produce slight deformation to make the corner piece body 10 fit more tightly and firmly with the door and window.

[0033] In this embodiment, the center line of the connection between the first corner piece 20 and the second corner piece 30 is a right-angled diagonal, and several protrusions 40 are symmetrically arranged relative to the right-angled diagonal; the adhesive groove 13 passes through the connection between the first corner piece 20 and the second corner piece 30 along the direction of the right-angled diagonal. The first corner piece 20 has a first insertion end 21 at the end furthest from the second corner piece 30, and the second corner piece 30 has a second insertion end 31 at the end furthest from the first corner piece 20.

[0034] Furthermore, a row of first protrusions 40 and a row of second protrusions 50 are symmetrically arranged relative to the right-angle diagonal. The first inclined surface 41 of each first protrusion 40 is inclined towards the first insertion end 21 and is connected to the first corner piece 20; the second inclined surface 51 of each second protrusion 50 is inclined towards the second insertion end 31 and is connected to the second corner piece 30. The number of first protrusions 40 and the number of second protrusions 50 are two or more.

[0035] Therefore, when the self-leveling glue-injecting corner piece of this utility model embodiment is assembled with the door and window frame, the corner piece body 10 is inserted into the door and window frame through the mutually perpendicular first corner piece 20 and second corner piece 30 respectively. During the insertion process, when the first protrusion 40 and the second protrusion 50 are about to contact the inner wall of the door and window frame, the row of first protrusions 40 near the first insertion end 21 can be smoothly inserted into the door and window frame by their respective first inclined surfaces 41. Similarly, the row of second protrusions 50 near the second insertion end 31 is also inserted into the door and window frame by their respective second inclined surfaces 51. In this way, the corner piece body 10 abuts against the inner wall of the door and window frame through the two rows of protrusions, and the deformation properties of the two rows of protrusions make the corner piece body 10 abut against the inner wall of the door and window frame, so that the corner piece body 10 will not be misaligned or loose, and the glue application when the corner piece body 10 is injected is more uniform. In other words, the self-leveling glued corner piece according to the embodiment of this utility model can not only automatically level and fix, but also make the connection between the corner piece body 10 and the door and window frame more stable and firm.

[0036] like Figure 9 and Figure 10 As shown, the length of the first protrusion 40 along the right-angle diagonal in each row can be designed to be different according to actual needs, and the length of the second protrusion 50 along the right-angle diagonal in each row can also be designed to be different according to actual needs.

[0037] Optionally, in some embodiments of this utility model, a groove 15 is provided on the connecting surface.

[0038] Optionally, in some embodiments of this utility model, the injection hole 14 is a round hole.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the self-leveling glue-injecting corner piece assembly of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
