Description

Technical Field

[0001] This utility model relates to the field of profile connection structure technology, and in particular to a profile corner connection structure. Background Technology

[0002] Profiles refer to solid straight bars of metal that have been plastically shaped and have a certain cross-sectional shape and size. Profiles come in a wide variety of specifications and have a wide range of uses. They play a very important role in rolling production. During the use of profiles, in order to better ensure the stability of the connection between profiles, it is necessary to fix the profiles through connection structures to ensure the stability of the connection between profiles.

[0003] In existing technologies, the connections at the corners of profiles mostly adopt a customized frame model, which can only adapt to specific size ranges or specific structures, resulting in poor versatility. Once customized, the profile frame cannot be adapted by cutting and adjusting it during subsequent construction. Utility Model Content

[0004] This utility model provides a profile corner connection structure to solve the problem of poor versatility in the prior art.

[0005] This utility model provides a profile corner connection structure, including a corner connector and a profile. The corner connector includes an L-shaped connecting groove and an L-shaped connecting cover. The L-shaped connecting cover is spliced ​​to the port of the L-shaped connecting groove. A first insertion part is fixedly connected to each end of the L-shaped connecting groove, and a second insertion part is fixedly connected to each end of the L-shaped connecting cover. The end of the profile is provided with a first connecting groove for the first insertion part to be inserted and a second connecting groove for the second insertion part to be inserted. The first insertion part is inserted into the first connecting groove, and the second insertion part is inserted into the second connecting groove to prevent the L-shaped connecting groove from detaching from the L-shaped connecting cover.

[0006] Furthermore, a limiting protrusion is fixedly connected to the side of the L-shaped connecting cover facing the L-shaped connecting groove. The limiting protrusion extends into the port of the L-shaped connecting groove, and the outer wall of the limiting protrusion contacts the inner wall of the L-shaped connecting groove.

[0007] Furthermore, the first plug portion includes a U-shaped plug portion, and the first connecting groove includes a first chamber for the U-shaped plug portion to be inserted into. The U-shaped plug portion contacts the side wall of the first chamber away from the second connecting groove, and the second plug portion contacts the side wall of the second connecting groove away from the first chamber.

[0008] Furthermore, the first insertion part also includes a square insertion part, and the first connecting groove includes a second chamber for the square insertion part to be inserted into, wherein the outer wall of the square insertion part is in contact with the inner wall of the second chamber.

[0009] Furthermore, a hollow weight-reducing cavity is provided inside the square plug-in portion.

[0010] Furthermore, the length of the square plug portion is greater than the length of the U-shaped plug portion and the length of the second plug portion, and the square plug portion has a chamfer at the end away from the L-shaped connecting groove.

[0011] Furthermore, it also includes a corner bracket, one end of which is fixedly connected to the corner connector, and the other end of which is fixedly connected to the profile.

[0012] Furthermore, the corner bracket is configured as a straight corner bracket, and the corner connector has corner connecting grooves at both ends for the end of the straight corner bracket to be inserted into.

[0013] Furthermore, the inner wall of the L-shaped connecting groove is fixedly connected with a plurality of reinforcing ribs, which are fixedly connected to the first insertion part.

[0014] The beneficial effects of this utility model are as follows:

[0015] The ends of two profiles are connected using corner connectors, and corner brackets are used to fix the profiles to the corner connectors. When the profile size needs to be adjusted, the ends of the profiles can be cut. The cut ends are then connected using corner connectors to form a frame, allowing for adjustment of the frame size and improving the versatility of the profile frame. The corner connectors are designed with L-shaped connecting grooves and L-shaped connecting caps, allowing for separate injection molding of the L-shaped connecting grooves and L-shaped connecting caps during the injection molding process, reducing the processing difficulty and manufacturing cost of the corner connectors. Simultaneously, when connecting the corner connectors to the profile ends, the L-shaped connecting grooves and L-shaped connecting caps are combined, with the first insertion part inserted into the first connecting groove and the second insertion part inserted into the second connecting groove. The first and second connecting grooves prevent the L-shaped connecting grooves and L-shaped connecting caps from disengaging. The corner brackets simultaneously fix the profiles to the corner connectors and achieve relative fixation of the L-shaped connecting grooves and L-shaped connecting caps, eliminating the need for additional fixing of the L-shaped connecting grooves and L-shaped connecting caps.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "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 construed as a limitation of this utility model.

[0029] The following is combined Figures 1-8 This utility model describes a profile corner connection structure, such as... Figure 1 As shown, the device includes a corner connector 1 and a profile 2. The corner connector 1 includes an L-shaped connecting groove 11 and an L-shaped connecting cover 12. The L-shaped connecting cover 12 is spliced ​​to the upper port of the L-shaped connecting groove 11. The two ends of the L-shaped connecting groove 11 are respectively fixedly connected to a first insertion part 3, and the two ends of the L-shaped connecting cover 12 are respectively fixedly connected to a second insertion part 4. The end of the profile 2 is provided with a first connecting groove 21 for the first insertion part 3 to be inserted and a second connecting groove 22 for the second insertion part 4 to be inserted. The first insertion part 3 is inserted into the first connecting groove 21, and the second insertion part 4 is inserted into the second connecting groove 22 to prevent the L-shaped connecting groove 11 from disengaging from the L-shaped connecting cover 12.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, the corner connector 1 is L-shaped, consisting of an L-shaped connecting groove 11 and an L-shaped connecting cover 12. When a corner connection is needed between the ends of two profiles 2, one end of the corner connector 1 is inserted into the end of one profile 2, and the other end is inserted into the end of the other profile 2. This causes the first insertion parts 3 at both ends to be inserted into the two first connecting grooves 21, and the second insertion parts 4 at both ends to be inserted into the two second connecting grooves 22. Then, corner brackets are used to securely connect the two profiles 2 to the corner connector 1.

[0031] This invention connects the ends of two profiles 2 using a corner connector 1. When the size of the profile 2 needs to be adjusted, the ends of the profile 2 can be cut. The cut ends of the profile 2 are then connected by the corner connector 1 to form a frame, thus achieving adjustment of the frame size and improving the versatility of the profile frame. By setting the corner connector 1 as an L-shaped connecting groove 11 and an L-shaped connecting cover 12, the L-shaped connecting groove 11 and the L-shaped connecting cover 12 can be injection molded separately during the injection molding of the corner connector 1, reducing the processing difficulty and manufacturing cost of the corner connector 1. Meanwhile, when connecting the corner connector 1 to the end of the profile 2, the L-shaped connecting groove 11 and the L-shaped connecting cover 12 are combined so that the first insertion part 3 is inserted into the first connecting groove 21 and the second insertion part 4 is inserted into the second connecting groove 22. The first connecting groove 21 and the second connecting groove 22 restrict the L-shaped connecting groove 11 and the L-shaped connecting cover 12 from separating from each other. While fixing the profile 2 and the corner connector 1 with the corner bracket, the relative fixation of the L-shaped connecting groove 11 and the L-shaped connecting cover 12 is achieved, without the need for additional fixation between the L-shaped connecting groove 11 and the L-shaped connecting cover 12.

[0032] Furthermore, a limiting protrusion 121 is fixedly connected to the side of the L-shaped connecting cover 12 facing the L-shaped connecting groove 11. The limiting protrusion 121 extends into the port of the L-shaped connecting groove 11, and the outer wall of the limiting protrusion 121 contacts the inner wall of the L-shaped connecting groove 11.

[0033] Specifically, such as Figure 2 , Figure 3 As shown, when splicing the L-shaped connecting groove 11 and the L-shaped connecting cover 12, the L-shaped connecting cover 12 is connected to the upper port of the L-shaped connecting groove 11, and the limiting protrusion 121 contacts the inner walls on both sides of the L-shaped connecting groove 11, thereby limiting the relative position of the L-shaped connecting cover 12 and the L-shaped connecting groove 11 in the horizontal direction, which improves the stability of the splicing of the L-shaped connecting groove 11 and the L-shaped connecting cover 12.

[0034] Furthermore, the first insertion part 3 includes a U-shaped insertion part 31, the first connecting groove 21 includes a first chamber 211 for the U-shaped insertion part 31 to be inserted into, the U-shaped insertion part 31 contacts the side wall of the first chamber 211 away from the second connecting groove 22, and the second insertion part 4 contacts the side wall of the second connecting groove 22 away from the first chamber 211.

[0035] Specifically, the L-shaped connecting groove 11 and the L-shaped connecting cover 12 are made of plastic and are respectively injection molded. For example... Figure 3 , Figure 4As shown, each end of the L-shaped connecting groove 11 is provided with two U-shaped insertion parts 31. The U-shaped insertion parts 31 are integrally formed with the L-shaped connecting groove 11, and the second insertion part 4 is integrally formed with the L-shaped connecting cover 12. When the corner connector 1 is connected to the profile 2, the second insertion part 4 contacts the top of the inner wall of the second connecting groove 22, and the U-shaped insertion part 31 contacts the bottom of the first chamber 211. This limits the relative position of the L-shaped connecting groove 11 and the L-shaped connecting cover 12 in the vertical direction when the U-shaped insertion part 31 is inserted into the first chamber 211 and the second insertion part 4 into the second connecting groove 22. No additional fixing is required between the L-shaped connecting groove 11 and the L-shaped connecting cover 12.

[0036] Furthermore, the first insertion part 3 also includes a square insertion part 32, and the first connecting groove 21 includes a second chamber 212 for the square insertion part 32 to be inserted into, and the outer wall of the square insertion part 32 is in contact with the inner wall of the second chamber 212.

[0037] Specifically, such as Figure 4 As shown, when the corner connector 1 is connected to the profile 2, the square plug part 32 is inserted into the second chamber 212 and fits against the inner wall of the second chamber 212, which limits the relative position of the corner connector 1 and the profile 2, and further improves the stability of the connection between the corner connector 1 and the profile 2.

[0038] Furthermore, a hollow weight-reducing cavity 33 is provided inside the square insertion part 32. For example... Figure 3 As shown, the hollow weight-reducing cavity 33 reduces the weight of the corner connector 1.

[0039] Furthermore, the length of the square plug portion 32 is greater than the length of the U-shaped plug portion 31 and the length of the second plug portion 4, and a chamfer 34 is provided at the end of the square plug portion 32 away from the L-shaped connecting groove 11.

[0040] Specifically, such as Figure 5 As shown, the length of the square plug portion 32 protruding from the end of the corner connector 1 is greater than the length of the U-shaped plug portion 31 and the second plug portion 4 protruding from the end of the corner connector 1. When the corner connector 1 is connected to the end of the profile 2, the square plug portion 32 first contacts the profile 2 and is inserted into the second chamber 212. The square plug portion 32, with one end having a chamfer 34, is first inserted into the second chamber 212 to guide and position the corner connector 1 and the profile 2, so that when the ends of the corner connector 1 and the profile 2 are further connected, the U-shaped plug portion 31 automatically aligns with the first chamber 211, and the second plug portion 4 automatically aligns with the second connecting groove 22.

[0041] Furthermore, it also includes corner brackets, one end of which is fixedly connected to the corner connector 1, and the other end of which is fixedly connected to the profile 2. The corner brackets are used to fix the corner connector 1 and the end of the profile 2.

[0042] Furthermore, such as Figure 6 As shown, the corner bracket is set as a straight corner bracket 5. The corner connector 1 has corner connecting grooves 13 at both ends for inserting the end of the straight corner bracket 5. The profile 2 has a profile connecting groove 23 at the end for inserting the other end of the straight corner bracket 5. One end of the straight corner bracket 5 is connected to the corner connecting groove 13 by bolt 51, and the other end of the straight corner bracket 5 is connected to the profile connecting groove 23 by bolt 51.

[0043] While inserting the corner connector 1 and the profile 2, insert the straight angle brackets 5 into the corner connecting grooves 13 respectively. After the corner connector 1 and the profile 2 are inserted, fix the two ends of the straight angle brackets 5 to the corner connector 1 and the profile 2 respectively by connecting bolts 51, so as to realize the fixed connection between the corner bracket connector and the profile 2.

[0044] Furthermore, the inner wall of the L-shaped connecting groove 11 is fixedly connected with multiple reinforcing ribs 6, and the reinforcing ribs 6 are fixedly connected to the first insertion part 3. For example... Figure 3 As shown, the reinforcing rib 6 is provided on the inner wall of the L-shaped connecting groove 11 and is integrally formed with the L-shaped connecting groove 11. The end of the reinforcing rib 6 is fixedly connected to the first insertion part 3 through integral forming, thereby improving the strength of the L-shaped connecting groove 11.

[0045] In one specific embodiment, such as Figure 7 As shown, a frame can be assembled by using four corner connectors 1 and four profiles 2. Both ends of the four profiles 2 are set as straight cuts, and the corner connectors 1 are located at the four corners of the frame, thereby connecting the four profiles 2 end to end to assemble the frame.

[0046] In another alternative embodiment, such as Figure 1 , Figure 8 As shown, a frame can be assembled using two corner profiles, two side profiles 9, one top profile 7, and one bottom profile 8. One end of the side profile 9 has a straight cut, and the other end has an angled cut. Both ends of the top profile 7 have straight cuts, and both ends of the bottom profile 8 have angled cuts. The plane of the straight cut is perpendicular to the length direction of the profile 2, and the plane of the angled cut forms a 45-degree angle with the length direction of the profile 2. The straight cuts of the side profile 9 and the top profile 7 are connected by two corner connectors 1. The angled cuts of the side profile 9 and the bottom profile 8 are fixedly connected by right-angle brackets 91. One side of the right-angle bracket 91 is fixed to the inside of the side profile 9 with screws, and the other side of the right-angle bracket 91 is fixed to the inside of the bottom profile 8 with screws, thus completing the frame assembly.
