Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a corner connector. Background Technology

[0002] An angle connector is installed at the corner of two fittings (such as a straight pipe) to connect them. Currently, angle connectors on the market are generally fixed angles, such as 45° and 90° angle connectors. Because the angle of the angle connector is fixed, it can only be installed at the corner of two fittings with a fixed angle. If there is an error in the angle between the two fittings or if the angle between the two fittings needs to be changed, the fixed angle angle connector cannot be used.

[0003] Among existing patents, Chinese patent application number 202321465187.3 discloses a corner connector for fixing a back rib. Its features include a first connecting arm and a second connecting arm, with one end of the first connecting arm and one end of the second connecting arm connected to each other via a pivot. The first and second connecting arms can rotate around the pivot to change the included angle between them. Both the first and second connecting arms are provided with back rib fixing holes. Although the first and second connecting arms in this patent can rotate relative to each other, when the first and second connecting arms are at an angle, the trapezoidal rotation areas on the first and second connecting arms extend outwards, resulting in an overall structure that is not neat or aesthetically pleasing, and making it difficult to assemble with straight pipes to form a mounting bracket.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a corner connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corner connector includes a rotating shaft, a first rotating plate rotatably connected to the rotating shaft, a second rotating plate rotatably connected to the rotating shaft, a first sleeve connector mounted on the first rotating plate, and a second sleeve connector mounted on the second rotating plate. The first sleeve connector has a first insertion hole in its axial direction, and the second sleeve connector has a second insertion hole in its axial direction. The relative rotation angle between the first rotating plate and the second rotating plate is in the range of 0° to 180°. When the first rotating plate and the second rotating plate rotate relative to each other to 0°, the first sleeve connector and the second sleeve connector are folded together. When the first rotating plate and the second rotating plate rotate relative to each other to 180°, the first sleeve connector and the second sleeve connector are coaxially spliced ​​together.

[0008] Furthermore, both the first and second sockets are through holes; when the first and second rotating plates rotate relative to each other to 180°, the first and second sockets are coaxially connected.

[0009] Furthermore, two rotating rings are provided on the same side of the first rotating plate, and a rotating sleeve is provided on the same side of the second rotating plate. The rotating sleeve is located between the two rotating rings and is coaxially arranged. The rotating shaft passes through one rotating ring, the rotating sleeve and the other rotating ring in sequence.

[0010] Furthermore, the first rotating plate is secured to the outer wall of the first set of connecting pipes by the first locking fastener.

[0011] Furthermore, the second rotating plate is secured to the outer wall of the second set of pipes via a second locking fastener.

[0012] Furthermore, the end of the first set of connecting pipes away from the rotating shaft is coaxially provided with a first insert connecting pipe, and the junction of the first insert connecting pipe and the first set of connecting pipes forms a first limiting step.

[0013] Furthermore, a second insertion pipe is coaxially protruded at the end of the second set of pipes away from the rotating shaft, and a second limiting step is formed at the junction of the second insertion pipe and the second set of pipes.

[0014] Furthermore, the first rotating plate is installed on the outer wall of the first connecting pipe or the inner wall of the first insertion hole, and the second rotating plate is installed on the outer wall of the second connecting pipe or the inner wall of the second insertion hole.

[0015] This utility model also provides a modular mounting bracket with corner connectors, including the aforementioned corner connectors, wherein the number of corner connectors is one or more.

[0016] Furthermore, a modular mounting bracket with a corner connector also includes several two-way connectors, several three-way connectors, several four-way connectors, several five-way connectors, and multiple straight pipes, which are detachably connected to the corner connectors, two-way connectors, three-way connectors, four-way connectors, or five-way connectors.

[0017] The beneficial effects of this utility model are as follows: In practical applications, one end of each of the two straight pipes is inserted into the first insertion hole of the first connecting pipe and the second insertion hole of the second connecting pipe, respectively. Since both the first and second rotating plates can rotate around the axis, both the first and second connecting pipes can also rotate around the axis. This allows for adaptive adjustment of the angle between the two straight pipes according to their relative angles, facilitating the assembly of the two straight pipes with this corner connector and meeting the needs of different usage scenarios with varying angles. Furthermore, when the first and second rotating plates rotate relative to each other to 0°, the first and second connecting pipes fold in half, resulting in a thicker straight pipe. When the first and second rotating plates rotate relative to each other to 180°, the first and second connecting pipes are coaxially spliced, with the two straight pipes on the same straight line, achieving the effect of connecting and extending the straight pipe. This utility model has a simple structure, low production cost, and is convenient to assemble, disassemble and use. It can adaptively adjust the included angle between the first set of connecting pipes and the second set of connecting pipes according to the actual rotation angle. It also has a large rotation angle range and good versatility. Attached Figure Description

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] Example 1.

[0028] like Figures 1 to 3 As shown, the present invention provides a corner connector, which includes a rotating shaft 1, a first rotating plate 2 rotatably connected to the rotating shaft 1, a second rotating plate 3 rotatably connected to the rotating shaft 1, a first sleeve pipe 4 installed on the first rotating plate 2, and a second sleeve pipe 5 installed on the second rotating plate 3. The first sleeve pipe 4 is provided with a first insertion hole 6 in the axial direction, and the second sleeve pipe 5 is provided with a second insertion hole 7 in the axial direction. The relative rotation angle range between the first rotating plate 2 and the second rotating plate 3 is 0° to 180°. When the first rotating plate 2 and the second rotating plate 3 rotate relative to each other to 0°, the first sleeve pipe 4 and the second sleeve pipe 5 are folded together. When the first rotating plate 2 and the second rotating plate 3 rotate relative to each other to 180°, the first sleeve pipe 4 and the second sleeve pipe 5 are coaxially spliced ​​together.

[0029] In practical applications, one end of each of the two straight tubes 18 is inserted into the first insertion hole 6 of the first connecting tube 4 and the second insertion hole 7 of the second connecting tube 5, respectively. Since both the first rotating plate 2 and the second rotating plate 3 can rotate around the rotating shaft 1, both the first connecting tube 4 and the second connecting tube 5 can also rotate around the rotating shaft 1. This allows the angle between the two straight tubes 18 to be adjusted according to the angle between them, which not only facilitates the assembly of the two straight tubes 18 with this corner connector but also meets the needs of different angle applications. In addition, when the first rotating plate 2 and the second rotating plate 3 rotate relative to each other to 0°, the first connecting tube 4 and the second connecting tube 5 are folded together, so that the two straight tubes 18 are folded together to achieve the effect of thickening the straight tubes 18. When the first rotating plate 2 and the second rotating plate 3 rotate relative to each other to 180°, the first connecting tube 4 and the second connecting tube 5 are coaxially spliced, and the two straight tubes 18 are on the same straight line, thus achieving the effect of connecting and extending the straight tubes 18. This utility model has a simple structure, low production cost, and is convenient to assemble, disassemble and use. It can adaptively adjust the included angle between the first set of connecting pipes 4 and the second set of connecting pipes 5 according to the actual rotation angle. It also has a large rotation angle range and good versatility.

[0030] In this embodiment, both the first insertion hole 6 and the second insertion hole 7 are through holes; when the first rotating plate 2 and the second rotating plate 3 rotate relative to each other to 180°, the first insertion hole 6 and the second insertion hole 7 are coaxially connected. In practical applications, when strengthening the strength of a specific position of a single straight pipe 18, the first rotating plate 2 and the second rotating plate 3 are rotated relative to each other to 180°, and then the straight pipe 18 is inserted into the first insertion hole 6 and the second insertion hole 7, so that the corner connector is assembled at the specific position of the straight pipe 18 to strengthen the strength of the specific position of the straight pipe 18, making the specific position of the straight pipe 18 less prone to bending or breaking. When it is necessary to connect and extend two straight pipes 18, rotate the first rotating plate 2 and the second rotating plate 3 to 180° relative to each other, and insert the two straight pipes 18 into the first insertion hole 6 of the first sleeve connector 4 and the second insertion hole 7 of the second sleeve connector 5, until the end faces of the two straight pipes 18 touch. At this time, the end faces of the two straight pipes 18 can also be welded together by welding, so that the two straight pipes 18 can be firmly connected and extended, and this corner connector can enhance the strength of the connection and extension position of the two straight pipes 18.

[0031] In this embodiment, two rotating rings 8 are provided on the same side of the first rotating plate 2, and a rotating sleeve 9 is provided on the same side of the second rotating plate 3. The rotating sleeve 9 is located between the two rotating rings 8 and is coaxially arranged. The rotating shaft 1 passes through one rotating ring 8, the rotating sleeve 9, and the other rotating ring 8 in sequence. The rotating rings 8 and the rotating sleeve 9 can rotate relative to the rotating shaft 1. This structural design facilitates the rotatable connection between the first rotating plate 2 and the second rotating plate 3 and the rotating shaft 1, allowing the first rotating plate 2 and the second rotating plate 3 to fold and rotate.

[0032] In this embodiment, the first rotating plate 2 is installed on the outer wall of the first connecting pipe 4, and the first rotating plate 2 is locked to the outer wall of the first connecting pipe 4 by the first locking fastener. This structural design not only facilitates the disassembly, assembly, and maintenance of the first rotating plate 2 and the first connecting pipe 4, but also ensures a firm connection between the two.

[0033] In this embodiment, the second rotating plate 3 is installed on the outer wall of the second connecting pipe 5, and the second rotating plate 3 is locked to the outer wall of the second connecting pipe 5 by the second fastener. This structural design not only facilitates the disassembly, assembly, and maintenance of the second rotating plate 3 and the second connecting pipe 5, but also ensures a firm connection between the two.

[0034] Specifically, both the first and second locking components can be locking bolts.

[0035] Example 2.

[0036] like Figure 4 and Figure 5As shown, in this embodiment, the first sleeve connector 4 has a first insertion connector 10 coaxially protruding at the end away from the rotating shaft 1, and a first limiting step 11 is formed at the junction of the first insertion connector 10 and the first sleeve connector 4. When the straight pipe 18 is a sleeve, the straight pipe 18 is sleeved on the outside of the first insertion connector 10 until the end face of the straight pipe 18 abuts against the first limiting step 11, proving that the straight pipe 18 and the first sleeve connector 4 are assembled in place, which improves the positional accuracy and stability of the assembly of the straight pipe 18 and the first sleeve connector 4; preferably, the outer diameter of the first sleeve connector 4 is equal to the outer diameter of the straight pipe 18, and the inner diameter of the straight pipe 18 is equal to the outer diameter of the first insertion connector 10, so that the first sleeve connector 4 and the straight pipe 18 are completely spliced.

[0037] In this embodiment, the second sleeve connector 5 has a second insertion connector 12 coaxially protruding at the end away from the rotating shaft 1, and a second limiting step 13 is formed at the junction of the second insertion connector 12 and the second sleeve connector 5. When the straight pipe 18 is a sleeve, the straight pipe 18 is sleeved on the outside of the second insertion connector 12 until the end face of the straight pipe 18 abuts against the second limiting step 13, proving that the straight pipe 18 and the second sleeve connector 5 are assembled in place, which improves the positional accuracy and stability of the assembly of the straight pipe 18 and the second sleeve connector 5; preferably, the outer diameter of the second sleeve connector 5 is equal to the outer diameter of the straight pipe 18, and the inner diameter of the straight pipe 18 is equal to the outer diameter of the second insertion connector 12, so that the second sleeve connector 5 and the straight pipe 18 are completely spliced.

[0038] In this embodiment, the first rotating plate 2 is installed on the inner side wall of the first insertion hole 6 of the first sleeve pipe 4, and the second rotating plate 3 is installed on the inner side wall of the second insertion hole 7 of the second sleeve pipe 5. This structural design conceals the first rotating plate 2 and the second rotating plate 3, making the structure of this corner connector simpler, more aesthetically pleasing, and more compact.

[0039] The remaining structures in this embodiment are the same as those in Embodiment 1. The same structures are explained using the analysis in Embodiment 1, and will not be repeated here.

[0041] like Figure 6 As shown, this utility model also provides a modular mounting bracket with corner connectors, including the aforementioned corner connectors, wherein the number of corner connectors is one or more. This modular mounting bracket with corner connectors possesses all the beneficial effects of the aforementioned corner connectors, which will not be elaborated further here.

[0042] This embodiment of a modular mounting rack with corner connectors also includes several two-way connectors 14, several three-way connectors 15, several four-way connectors 16, several five-way connectors 17, and multiple straight pipes 18. The straight pipes 18 are detachably connected to the corner connectors, two-way connectors 14, three-way connectors 15, four-way connectors 16, or five-way connectors 17. In practical applications, the mounting rack can be assembled by combining multiple straight pipes 18 with the required number of corner connectors, two-way connectors 14, three-way connectors 15, four-way connectors 16, and five-way connectors 17 according to actual needs. This modular assembly of the mounting rack facilitates storage, packaging, and transportation, and allows for the assembly of mounting racks of different sizes, specifications, or shapes as needed.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
