Description

Technical Field

[0001] The utility model relates to a door frame positioning structure, and more particularly to an attached frame corner code structure and an attached frame connecting structure thereof. Background Art

[0002] Supplementary frames serve to determine the size and position of doors and windows. Generally, after a building's door and window openings are constructed, their dimensions may not be standardized. Installing supplementary frames allows for more precise determination of these dimensions. Large-scale projects often require supplementary frames for greater standardization. Once the opening is finished, or nearly finished, the supplementary frames can be installed to ensure proper positioning.

[0003] Chinese Patent Publication No. CN214786952U, entitled "Split Corner Bracket and Door / Window Panel Frame Using the Split Corner Bracket," discloses a split corner bracket and a door / window panel frame using the split corner bracket. The split corner bracket comprises a first corner bracket body and a second corner bracket body, with at least one set of positioning posts disposed between the first and second corner bracket bodies. The positioning posts comprise a sleeve and a top post that engages with the sleeve. The sleeve is connected to the first corner bracket body, and the top post is connected to the second corner bracket body. Corner bracket connection holes are respectively provided on the outer surfaces of the first and second corner bracket bodies. This invention prevents the expansion and extrusion of the profile and ensures that the corner bracket does not sway laterally within the profile, thereby improving the flatness and stability of the door / window panel frame corner assembly. Traditional split frame-attached corner brackets require on-site assembly using fasteners, which is relatively cumbersome. Summary of the Invention

[0004] The utility model overcomes the disadvantage of the existing split frame-attached corner bracket structure that is inconvenient to assemble, and provides a frame-attached corner bracket structure that simplifies assembly and operation.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A frame-attached angle bracket structure includes two connecting pins and an angle bracket body. The two connecting pins are arranged vertically. Wedge teeth are provided on the side walls in the height direction of the connecting pins. Through the wedge teeth, the distance between the opposing surfaces gradually decreases from the fixed end to the free end. The free end of the connecting pin is provided with a narrowing portion, which shortens the length of the connecting pin in the width direction.

[0007] The angle bracket structure connects to the auxiliary frame via connecting pins. Compared to existing fastener-based connections, this application utilizes wedge teeth for an interference fit, achieving pre-fixation. The wedge teeth are positioned on one or both opposing side walls in the height direction of the connecting pins. With one end higher than the other, the wedge teeth ensure a tighter fit as the connecting pins are inserted deeper into the auxiliary frame, effectively securing the connection.

[0008] In order to make it easier for the connecting pin to be inserted into the auxiliary frame, a narrowing portion is provided at the free end of the connecting pin, and the narrowing portion plays a guiding role.

[0009] By setting the narrowing part and the wedge teeth on the connecting pins, the angle code structure can be pre-positioned with the auxiliary frame in the form of plug-in, which simplifies assembly and saves workers' time.

[0010] Preferably, the number of wedge teeth is several, and the peak height of the wedge teeth gradually decreases from the fixed end to the free end. When the auxiliary frame is inserted, damping is formed, and the fit becomes tighter and tighter as the depth of insertion into the auxiliary frame increases.

[0011] Preferably, both side walls in the height direction of the connecting pins are provided with wedge teeth. The wedge teeth structure on both side walls can make the force during interference fit more uniform and avoid stress concentration.

[0012] Preferably, the two side walls are provided with symmetrical planes, and the wedge teeth on the two side walls are symmetrical about the symmetrical planes.

[0013] Preferably, the angle bracket body is provided with a plurality of groups of vertically arranged connecting pins, and the projections of the connecting pins of each group on a plane perpendicular to the axis of the angle bracket body coincide with each other. By providing multiple groups of connecting pins, the bending moment is reduced.

[0014] Preferably, two groups of connecting pins are provided on the angle code body.

[0015] Preferably, the narrowing portion includes a transition section and a parallel section, wherein the angle between the widthwise sides of the transition section is 45 degrees, and the widthwise sides of the parallel section are parallel to the lengthwise direction of the connecting pin. This feature, by narrowing the head of the connecting pin by the transition section, makes it easier to insert the connecting pin into the attachment frame.

[0016] As a preferred option, the connecting pins and the angle code body are integrated into one structure, which is easy to store and transport, saves assembly time, and is convenient for customers to use without having to distinguish them.

[0017] A frame attachment connection structure includes the frame attachment angle bracket structure and frame attachment profile as described above, wherein the connecting pins are inserted into the holes of the frame attachment profile and have an interference fit with the holes. The connecting pins are fixedly connected to the frame attachment profile in an interference fit manner.

[0018] Preferably, the frame attachment profile is provided with grouting grooves at both ends in the width direction, and the angle bracket body is provided with grouting holes and connecting grooves at both ends in the length direction, with the connecting grooves connecting the grouting holes and the grouting grooves. This structure allows cement mortar to be continuously filled into the grouting holes and the connecting grooves to fully secure the frame attachment profile and the angle bracket.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) By setting the narrowing part and the wedge teeth on the connecting pin, the angle code structure can be pre-positioned with the auxiliary frame in the form of plug-in, which simplifies assembly and saves workers' time.

[0021] (2) The structure in which one end of the wedge tooth is larger than the other end can use friction to prevent it from falling off after insertion. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example:

[0033] A frame-attached angle bracket structure includes two connecting pins 1 and an angle bracket body 2. The two connecting pins 1 are arranged vertically. Wedge teeth 3 are provided on the side walls of the connecting pins 1 in the height direction. Through the wedge teeth 3, the distance between the opposing surfaces gradually decreases from the fixed end to the free end. The free end of the connecting pin 1 is provided with a narrowing portion 6, which shortens the length of the connecting pin 1 in the width direction.

[0034] The narrowing portion 6 includes a transition section 4 and a parallel section 5. The width of the transition section 4 forms a 45-degree angle, while the width of the parallel section 5 is parallel to the length of the connector pin 1. This feature, by narrowing the head of the connector pin 1 through the transition section 4, makes it easier to insert the connector pin 1 into the attachment frame.

[0035] The connecting pin 1 and the angle bracket body 2 are an integrated structure, which is easy to store and transport, but the present invention is not limited to this.

[0036] Wedge teeth 3 are provided on both sides of the connecting pin 1 in the height direction. The presence of wedge teeth 3 on both sides ensures a more uniform force distribution during the interference fit, avoiding stress concentration. The two sides are provided with symmetrical planes, and the wedge teeth 3 on the two sides are symmetrical about the symmetrical planes, but this is not limiting.

[0037] The angle bracket body 2 is provided with several sets of vertically arranged connecting pins 1. The projections of each set of connecting pins on a plane perpendicular to the axis of the angle bracket body 2 overlap. By providing multiple sets of connecting pins 1, bending moments are reduced. The angle bracket body 2 is provided with two sets of connecting pins 1, but this is not limiting.

[0038] Ginseng Figure 1 As shown, in some embodiments, there are a plurality of wedge teeth 3, and the peak height of the wedge teeth 3 gradually decreases from the fixed end to the free end. When inserting the auxiliary frame, damping is formed, and the fit becomes tighter as the insertion depth of the auxiliary frame increases.

[0039] Ginseng Figure 2 As shown, in other embodiments, the number of the wedge tooth 3 is one, the length of the wedge tooth 3 is slightly shorter than the length of the connecting pin 1, and the top height thereof gradually decreases from the fixed end to the free end.

[0040] Ginseng Figure 3As shown, a frame attachment connection structure includes a frame attachment angle bracket structure and a frame attachment profile 7 as described above. The connecting pin 1 is inserted into the hole of the frame attachment profile 7 and has an interference fit with the hole. The connecting pin 1 is fixedly connected to the frame attachment profile 7 in an interference fit manner.

[0041] The width of the connecting pin 1 is shorter than the width of the hole. The height of the head of the connecting pin 1 is also shorter than the height of the hole. As the insertion depth increases, the connecting pin 1 and the frame profile 7 gradually change from a clearance fit to an interference fit. As the insertion depth increases, the friction between the two also increases.

[0042] The attachment frame profile 7 is provided with grouting grooves 8 at both ends in the width direction, and the angle bracket body 2 is provided with grouting holes 9 and connecting grooves 10 at both ends in the length direction. The connecting grooves 10 connect the grouting holes 9 and the grouting grooves 8. This structure allows cement mortar to be continuously filled into the grouting holes 9 and the connecting grooves 10 to fully fix the attachment frame profile 7 and the angle bracket.

[0043] The angle bracket structure connects to the auxiliary frame via connecting pins 1. Compared to existing fastener-based connections, this application utilizes wedge teeth 3 for an interference fit, achieving pre-fixation. The wedge teeth 3 are positioned on one or both opposing side walls of the connecting pin 1. The wedge teeth 3 are designed with one end higher than the other, ensuring a tighter fit as the connecting pin 1 is inserted deeper into the auxiliary frame, effectively securing the connection.

[0044] In order to make it easier for the connecting pin 1 to be inserted into the auxiliary frame, a narrowing portion 6 is provided at the free end of the connecting pin 1 , and the narrowing portion 6 serves as a guide.

[0045] By setting the narrowed portion 6 and the wedge teeth 3 on the connecting pin 1, the angle code structure can be pre-positioned with the auxiliary frame in the form of plug-in, which simplifies assembly and saves workers' time.

[0046] The above-described embodiments are only preferred solutions of the present invention and do not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
