Description

Technical Field

[0001] The utility model relates to the technical field of profile assembly, in particular to an improved solid angle bracket and a profile connection structure. Background Art

[0002] Angle brackets are commonly used hardware, usually used in accessories for doors, windows, furniture, curtain walls, etc. They are used as supporting products for industrial manufacturing, semi-finished products, and tools used in the production process. Common angle brackets are sheet structures with two angle bracket arms, which are usually used to fix profiles. The frame construction in the construction field or the support structure construction in the industrial field often requires the assembly of angle brackets at the corners between two profiles to allow the two profiles that are vertically connected to each other to be fixed to each other.

[0003] like Figure 1 and Figure 2 As shown, in existing conventional applications, when the frame construction process requires two profiles to be butted at right angles to each other, the common practice is to cut off a portion of the end of the profile at an angle, so that the ends of the two profiles form a slope respectively. Since the ends have slopes, the two profiles that are butted at right angles to each other can be butted together at the corners through the slopes. This structure can not only achieve the right-angle butt connection of the two profiles, but also has obvious aesthetics. This butt connection method is also commonly used in indoor decorative ceiling structures. Accordingly, in order to cooperate with this butt connection method, such as Figure 3 and Figure 4 As shown, the angle code structure of the prior art is generally set as a flat sheet structure, and the two connecting arms of the angle code are respectively sleeved in two profiles that are vertically connected to each other. After the inclined surfaces of the two profiles are assembled with each other, the corner part of the angle code can just fall into the assembled position of the inclined surfaces of the two profiles. Finally, the connecting arms of the angle code are fixedly connected to the profile by screws, and the two profiles that are connected to each other can be completely fixedly connected.

[0004] However, in actual frame construction, a certain number of main bones and auxiliary bones are often required to be connected to each other inside the frame. The number of these two types of profiles is relatively large, and a certain number of main bones and auxiliary bones need to be connected to each other at right angles. If the ends of each main bone and auxiliary bone are processed into inclined surfaces in the above-mentioned previous method, a large amount of material waste will be caused. Figure 5 and Figure 6 As shown in the figure, the ends of the main and auxiliary bones without bevels are still flat, so the two profiles are directly connected at right angles through the existing flat angle brackets. The ends of the two profiles are blocked by the corners of the angle brackets, and the displacement is restricted. Therefore, the ends of the two profiles cannot be joined together, and an obvious gap appears at the corner where they are connected. On the one hand, it affects the aesthetics, and on the other hand, it also affects the structural strength of the two profiles after being connected. In addition, if Figure 7As shown, in addition to being vertically connected to the ends of the main bones, in order to strengthen the structural strength of the profile frame, it is often necessary to vertically connect multiple arranged secondary bones between the two ends of the main bones. The traditional connection method is to fix the ends of each secondary bone to the main bone by screws or welding. This connection method can only connect each secondary bone to the main bone one by one during actual operation. In particular, when constructing the profile frame at high altitude, the secondary bones are prone to falling, which makes the profile connection and installation process more cumbersome. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the utility model provides an improved three-dimensional corner code and a profile connection structure, which can not only fix and connect two profiles that are butt-jointed at right angles, but also avoid the appearance of gaps at the corners of the two profiles that are butt-jointed at right angles, effectively avoid affecting the aesthetics and structural strength of the two profiles after being butt-jointed at right angles, and can help to simplify the connection and installation process of the profiles.

[0006] The utility model provides an improved solid angle bracket, comprising a first connecting plate and a second connecting plate which are arranged at right angles to each other, and also comprising a lifting plate, a first L-shaped support and a second L-shaped support;

[0007] The lifting plate is parallel to the first connecting plate and the second connecting plate and is at a different plane height from the first connecting plate and the second connecting plate;

[0008] One corner surface of the first L-shaped support is vertically connected to the lifting plate, and the other corner surface is parallelly connected to the first connecting plate;

[0009] One corner surface of the second L-shaped support is vertically connected to the lifting plate, and the other corner surface is parallelly connected to the second connecting plate.

[0010] The lifting plate is integrally formed with the first connecting plate, the second connecting plate, the first L-shaped support and the second L-shaped support.

[0011] The corners of the first L-shaped support and the second L-shaped support are formed with first rounded corners.

[0012] Second chamfered corners are respectively formed at the joints between the first L-shaped support and the second L-shaped support and the lifting plate.

[0013] The width of the lifting plate and the first L-shaped support in the length direction of the first connecting plate is smaller than that of the first connecting plate;

[0014] The width of the lifting plate and the second L-shaped support in the length direction of the second connecting plate is smaller than that of the second connecting plate.

[0015] The first connecting plate and the second connecting plate are respectively formed with arc ends at one end away from the lifting plate.

[0016] A plurality of screw holes are arranged on the first connecting plate and the second connecting plate respectively.

[0017] The screw hole is a cross-shaped screw hole.

[0018] Also included are at least two welding slots;

[0019] Each of the welding grooves is respectively opened on the first connecting plate and the second connecting plate along the length direction of the first connecting plate and the second connecting plate.

[0020] The utility model also provides a profile connection structure, comprising a main bone and a secondary bone, and also comprising an improved solid angle bracket of the utility model, wherein a first connecting plate and a second connecting plate of the solid angle bracket are respectively inserted into the slide grooves of the main bone and the secondary bone;

[0021] The lifting plate of the three-dimensional angle code is higher than the slide groove of the main bone to avoid the main bone.

[0022] The difference between an improved three-dimensional corner bracket of the utility model and the existing flat corner bracket is that a lifting plate is added between the first connecting plate and the second connecting plate which are arranged at right angles to each other. While the lifting plate is parallel to the first connecting plate and the second connecting plate, it is also at a different plane height from the first connecting plate and the second connecting plate, thus changing the previous flat structure of the corner bracket, and further adding a first L-shaped support and a second L-shaped support, so that one of the corner surfaces of the first L-shaped support is vertically connected to the lifting plate, and the other corner surface is parallel to the first connecting plate. Similarly, one of the corner surfaces of the second L-shaped support is vertically connected to the lifting plate, and the other corner surface is parallel to the second connecting plate. In this way, the lifting plate can be stably lifted to a certain height, and fixedly separated from the first connecting plate and the second connecting plate by a certain height difference, which is equivalent to The butt joint corners of the first connecting plate and the second connecting plate are arched to a certain height so that the originally flat corner code becomes three-dimensional. Therefore, when used for connecting profiles, the first connecting plate and the second connecting plate of the three-dimensional corner code are respectively inserted into the slide grooves of the main bone and the auxiliary bone, so that the main bone and the auxiliary bone can be pre-connected through the three-dimensional corner code. Since the corners of the three-dimensional corner code are lifting plates raised to a certain height, when the main bone and the auxiliary bone are butt jointed at right angles to each other, the corners of the three-dimensional corner code can avoid the main bone or the auxiliary bone. In the process of inserting the first connecting plate into the main bone slide groove, the main bone will not be hindered by the corners of the three-dimensional corner code. The corners of the three-dimensional corner code can continue to enter the main bone with the first connecting plate and overlap with the main bone. In this way, the two ends of the profiles can be smoothly spliced ​​together, avoiding gaps at the corners of the two right-angled profiles, thereby effectively avoiding affecting the aesthetics and structural strength of the two profiles after right-angle butt joint. In addition, since the corners of the solid angle code can avoid the main bone and are no longer restricted by the corners of the solid angle code, the auxiliary bone connected to the second connecting plate can continue to move along the direction of the slide groove of the main bone with the first connecting plate. Therefore, when it is necessary to connect multiple auxiliary bones between the two ends of the main bone, it is only necessary to pre-insert the solid angle code of this embodiment on each auxiliary bone, and then insert the first connecting plate of each solid angle code into the slide groove of the main bone in turn, and multiple auxiliary bones can be easily and quickly preliminarily connected to the main bone. Finally, multiple auxiliary bones can be completely fixed to the main bone by screws or welding. The installation process is obviously simpler, which helps to simplify the connection and installation process of the profiles. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] like Figure 8 and Fig.10 As shown, an improved solid corner bracket of the present embodiment includes a first connecting plate 1 and a second connecting plate 2 that are arranged at right angles to each other, and further includes a lifting plate 3, a first L-shaped support 4, and a second L-shaped support 5. The lifting plate 3 is parallel to the first connecting plate 1 and the second connecting plate 2, and the lifting plate 3 and the first connecting plate 1 and the second connecting plate 2 are at different plane heights. One of the corner surfaces of the first L-shaped support 4 is vertically connected to the lifting plate 3, and the other corner surface is parallelly connected to the first connecting plate 1. Similarly, one of the corner surfaces of the second L-shaped support 5 is vertically connected to the lifting plate 3, and the other corner surface is parallelly connected to the second connecting plate 2.

[0045] It can be understood that the difference between the improved three-dimensional corner bracket of the present embodiment and the existing flat corner bracket is that a lifting plate 3 is added between the first connecting plate 1 and the second connecting plate 2 which are arranged at right angles to each other. The lifting plate 3 is parallel to the first connecting plate 1 and the second connecting plate 2, and is also at a different plane height from the first connecting plate 1 and the second connecting plate 2, thus changing the flat structure of the traditional corner bracket. In addition, a first L-shaped support 4 and a second L-shaped support 5 are added, so that one of the corner surfaces of the first L-shaped support 4 is vertically connected to the The lifting plate 3 has another corner surface connected in parallel to the first connecting plate 1. Similarly, one corner surface of the second L-shaped support 5 is vertically connected to the lifting plate 3, and the other corner surface is connected in parallel to the second connecting plate 2. In this way, the lifting plate 3 can be stably lifted to a certain height, and a certain height difference is fixed between the first connecting plate 1 and the second connecting plate 2, which is equivalent to arching the butt corner of the first connecting plate 1 and the second connecting plate 2 to a certain height, so that the originally flat corner code becomes a three-dimensional shape, and the corner of the corner code is arched. Therefore, when used for connecting profiles, such as Fig.11 and Fig.13 As shown, the first connecting plate 1 and the second connecting plate 2 of the solid angle code are respectively inserted into the slide groove 400 of the main bone 100 and the auxiliary bone 200, so that the main bone 100 and the auxiliary bone 200 can be pre-connected through the solid angle code 300 of the utility model. Since the corner of the solid angle code 300 is a lifting plate 3 raised to a certain height, when the main bone 100 and the auxiliary bone 200 are connected to each other at right angles, the corner of the solid angle code 300 can avoid the main bone 100 or the auxiliary bone 200. During the process of the first connecting plate 1 being inserted into the slide groove of the main bone 100, the main bone 100 will not be hindered by the corner of the solid angle code. The corner of the solid angle code 300 can continue to enter the main bone 100 with the first connecting plate 1 and overlap with the main bone 100. In this way, the ends of the two profiles can be smoothly spliced ​​with each other, avoiding gaps at the corners of the two right-angled profiles, thereby effectively avoiding affecting the aesthetics and structural strength of the two profiles after the right-angle connection. In addition, as Fig.14 As shown, since the corner of the solid angle code 300 can avoid the main bone 100 and is no longer restricted by the corner of the solid angle code, the auxiliary bone 200 plugged into the second connecting plate 2 can continue to move along the direction of the slide groove 400 of the main bone 100 with the first connecting plate 1. Therefore, when it is necessary to connect multiple auxiliary bones 200 between the two ends of the main bone 100, it is only necessary to pre-plug the solid angle code 300 of this embodiment on each auxiliary bone 200, and then insert the first connecting plate 1 of each solid angle code 300 into the slide groove 400 of the main bone 100 in turn, and multiple auxiliary bones 200 can be easily and quickly preliminarily connected to the main bone 100. Finally, the multiple auxiliary bones 200 can be completely fixed to the main bone 100 by screws or welding. The installation process is obviously simpler, which helps to simplify the connection and installation process of the profiles.

[0046] Specifically, the lifting plate 3 of this embodiment is integrally formed with the first connecting plate 1, the second connecting plate 2, the first L-shaped support 4 and the second L-shaped support 5 through sheet metal parts, so that the batch manufacturing of the corner bracket can be facilitated and the structural strength of the three-dimensional corner bracket can be ensured. In addition, the first L-shaped support 4 and the second L-shaped support 5 themselves have first chamfers 6 formed at their corners, and the first L-shaped support 4 and the second L-shaped support 5 are respectively formed with second chamfers 7 at the joints with the lifting plate 3, which can also help to strengthen the overall structural strength of the three-dimensional corner bracket.

[0047] In addition, the width of the lifting plate 3 and the first L-shaped support 4 in the length direction of the first connecting plate 1 is smaller than that of the first connecting plate 1. Similarly, the width of the lifting plate 3 and the second L-shaped support 5 in the length direction of the second connecting plate 2 is smaller than that of the second connecting plate 2. This structure can make the first connecting plate 1 and the second connecting plate 2 have better resilience, so that the profiles can have better impact resistance after being connected.

[0048] Optionally, the first connecting plate 1 and the second connecting plate 2 are respectively formed with an arc-shaped end 8 at one end away from the lifting plate 3, so that the first connecting plate 1 and the second connecting plate 2 can be inserted into the sliding groove of the profile more smoothly.

[0049] More specifically, a plurality of screw holes 9 are arranged on the first connecting plate 1 and the second connecting plate 2, respectively, so as to fix the first connecting plate 1 and the second connecting plate 2 to the profile by screwing. Fig.15 As shown, the screw hole 9 is a cross-shaped screw hole, which makes it easier to install the screw. Fig.16 As shown, at least two welding grooves 10 are also included, and each welding groove 10 is opened on the first connecting plate 1 and the second connecting plate 2 along the length direction of the first connecting plate 1 and the second connecting plate 2, so that it is more convenient to fix the first connecting plate 1 and the second connecting plate 2 on the profile by welding.

[0050] Based on the above, combined again Figures 8 to 14As shown, the present embodiment also implements a profile connection structure, which includes a main bone 100 and a sub-bone 200, and an improved solid corner code 300 including the above-mentioned present embodiment, wherein the first connecting plate 1 and the second connecting plate 2 of the solid corner code 300 are respectively inserted into the slide grooves 400 of the main bone 100 and the sub-bone 200; the lifting plate 3 of the solid corner code 300 is higher than the slide groove 400 of the main bone 100 to avoid the main bone 100. The profile connection structure of this embodiment can make the lifting plate 3 stably lifted to a certain height, and fixedly separated from the first connecting plate 1 and the second connecting plate 2 by a certain height difference, which is equivalent to arching the joint corner of the first connecting plate 1 and the second connecting plate 2 to a certain height, so that the originally flat corner code becomes a three-dimensional shape, and the corner of the corner code is arched. Therefore, when used for the connection of profiles, the first connecting plate 1 and the second connecting plate 2 of the three-dimensional corner code are respectively inserted into the slide groove 400 of the main bone 100 and the auxiliary bone 200, so that the main bone 100 and the auxiliary bone 200 can be pre-connected through the three-dimensional corner code 300 of the utility model. Since the corner of the three-dimensional corner code 300 is a lifting The lifting plate 3 is raised to a certain height, so when the main bone 100 and the auxiliary bone 200 are connected to each other at right angles, the corner of the solid corner code 300 can avoid the main bone 100 or the auxiliary bone 200. During the process of inserting the first connecting plate 1 into the sliding groove of the main bone 100, the main bone 100 will not be hindered by the corner of the solid corner code. The corner of the solid corner code 300 can continue to enter the main bone 100 with the first connecting plate 1 and overlap with the main bone 100. In this way, the two ends of the profiles can be smoothly spliced ​​with each other, avoiding gaps at the corners of the two right-angled profiles, thereby effectively avoiding affecting the aesthetics and structural strength of the two profiles after the right-angle connection. In addition, since the corners of the solid angle code 300 can avoid the main bone 100 and are no longer restricted by the corners of the solid angle code, the auxiliary bone 200 plugged into the second connecting plate 2 can continue to move along the direction of the slide groove 400 of the main bone 100 with the first connecting plate 1. Therefore, when it is necessary to connect multiple auxiliary bones 200 between the two ends of the main bone 100, it is only necessary to pre-plug the solid angle code 300 of this embodiment on each auxiliary bone 200, and then insert the first connecting plate 1 of each solid angle code 300 into the slide groove 400 of the main bone 100 in turn, and the multiple auxiliary bones 200 can be easily and quickly preliminarily connected to the main bone 100. Finally, the multiple auxiliary bones 200 can be completely fixed to the main bone 100 by screws or welding. The installation process is obviously simpler, which helps to simplify the connection and installation process of the profile.
