Description

Technical Field

[0001] The utility model relates to a corner connector and a frame. Background Art

[0002] Racks are typically constructed from tubular components. Racks are typically divided into two types: planar and three-dimensional. Planar racks typically consist of four tubular components connected end-to-end to form a rectangular shape. Three-dimensional racks (such as multi-layer shelves used in supermarkets or multi-layer display racks used in exhibitions) are typically constructed from horizontal, vertical, and vertical mounting tubes. For example, at a corner of a three-dimensional rack, the horizontal mounting tubes are arranged horizontally, the vertical mounting tubes are arranged vertically, and the vertical mounting tubes are arranged vertically. The ends of the three tubes are fixed together. Therefore, corner connectors are commonly used components in rack construction.

[0003] For example, CN112038891B discloses an angle connector, which includes a fixed body and a connecting rod, wherein the fixed body is provided with multiple first connecting surfaces, one end of the connecting rod is connected to the first connecting surface, and the other end extends in a direction away from the first connecting surface, and the connecting rod is used to connect to the object to be connected.

[0004] The above-mentioned corner connectors can be used as connectors to form an overall frame. The corner connectors are connected to the objects to be connected using connecting rods, avoiding the use of welding. When the overall frame needs to be moved, the corner connectors are disassembled, and the components of the overall frame can be disassembled and moved, thereby improving the convenience of movement.

[0005] For the above-mentioned connecting member, two or more connecting rods cannot be directly connected. The assembly of multiple connecting rods can only be attached to the fixed body. Therefore, during manufacturing, both the fixed body and the connecting rods must be produced, which will undoubtedly increase the cost. Utility Model Content

[0006] The utility model provides an angle connector and a frame capable of reducing costs.

[0007] The technical solutions to the above technical problems are as follows:

[0008] The corner connector includes a rod-shaped component having a plurality of first mounting surfaces, each of which is provided with a first mounting hole, and at least a portion of an inner wall surface of the first mounting hole is threaded;

[0009] It also includes a first connecting screw, which cooperates with any first mounting surfaces on any two rod-shaped components, and the first mounting holes on the two first mounting surfaces correspond to each other, and are threadedly connected to the corresponding first mounting holes through the first connecting screw.

[0010] A frame comprises a plurality of hollow tubes, wherein each hollow tube is fitted with a rod-shaped component.

[0011] Since the rod-shaped components of the present invention are provided with first mounting holes on multiple first mounting surfaces, when two rod-shaped components are assembled, any two first mounting surfaces on the two rod-shaped components can be matched, and then the threaded holes on the two rod-shaped components can be connected by a first connecting screw to fasten the two rod-shaped components into one. Since the structure of each rod-shaped component is the same, no additional parts (such as the fixed body in the background art) need to be added to the rod-shaped components of the present invention, which not only reduces costs, but also allows multiple rod-shaped components in the present invention to be directly assembled into the required structure. In addition, the present invention can form angle connectors of different structures through rod-shaped components of the same structure. Therefore, it has universality for rod-shaped components, which not only simplifies the production process and cost, but also is more convenient during assembly and very simple during disassembly.

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0028] like Figure 1 and Figure 12 As shown, the corner connector of the present invention includes a rod-shaped component 1 and a first connecting screw 10. The rod-shaped component 1 has multiple first mounting surfaces 2. In the present invention, the rod-shaped component 1 is rectangular, and therefore the multiple first mounting surfaces 2 on the rod-shaped component are the front side, rear side, left side, right side, top side, and bottom side of the rod-shaped component 1. The length L0 of the rod-shaped component 1 is greater than the height L1, and the height L1 and width L2 of the rod-shaped component 1 are equal. Therefore, the left and right sides of the rod-shaped component 1 are square. According to this sizing, when the first mounting surfaces 2 of any two rod-shaped components 1 are mated, a step is avoided between the two rod-shaped components 1, that is, one rod-shaped component 1 does not protrude beyond the first mounting surface 2 of another rod-shaped component 1.

[0029] A first mounting hole 3 is provided on each first mounting surface 2, that is, a first mounting hole 3 is provided on the front side, rear side, left side, right side, upper side, and lower side of the rod-shaped component 1. The axes of any two adjacent first mounting holes 3 on the rod-shaped component 1 are perpendicular, and the first mounting holes 3 on different first mounting surfaces 2 of the rod-shaped component 1 are interconnected.

[0030] At least a portion of the inner wall surface of the first mounting hole 3 has a thread. When any first mounting surfaces 2 on any two rod-shaped components 1 are matched, the first mounting holes 3 on the two first mounting surfaces 2 correspond to each other and are threadedly connected to the corresponding first mounting holes 3 through the first connecting screws 10. That is, the first connecting screws 10 are respectively threadedly connected to the first mounting holes 3 on the two first mounting surfaces 2, so that the two rod-shaped components 1 are fastened into one.

[0031] In the present invention, the distance between the first mounting hole 3 located on the front side, rear side, upper side and lower side of the rod-shaped component 1 and the right side is greater than the distance between the first mounting hole 3 and the left side (such as Figure 2 ), such an arrangement, when a plurality of rod-shaped components 1 are connected by a first screw, can advantageously shorten the length of the first connecting screw 10, thereby saving costs.

[0032] Since the rod-shaped component 1 of the present invention has a first mounting hole 3 on each of the multiple first mounting surfaces 2, when two rod-shaped components 1 are assembled, any two first mounting surfaces on the two rod-shaped components 1 can be matched, and then the threaded holes 3 on the two rod-shaped components 1 can be connected by a first connecting screw 10 to fasten the two rod-shaped components 1 into one. Since the structure of each rod-shaped component 1 is the same, there is no need to add additional parts to the rod-shaped component 1 of the present invention (extra parts such as the fixed body in the background art), which not only reduces costs, but also multiple rod-shaped components 1 in the present invention can be directly assembled into the required structure, such as Figure 3 As shown in a to 3e, for example, two rod-shaped components 1 are spliced ​​to form a two-way pipe connection structure, three rod-shaped components 1 are spliced ​​to form a three-way pipe connection structure, four rod-shaped components 1 are spliced ​​to form a four-way pipe connection structure, five rod-shaped components 1 are spliced ​​to form a five-way pipe connection structure, and six rod-shaped components 1 can be spliced ​​to form a six-way pipe connection structure.

[0033] like Figure 4 As shown, the present invention further includes a wire 4. The rod-shaped component 1 is provided with a plurality of second mounting holes 5, with wires 4 fitting into at least some of the second mounting holes 5. In the present invention, preferably, each first mounting surface 2 of the rod-shaped component 1 is provided with a second mounting hole 5, and the second mounting holes 5 on different first mounting surfaces 2 of the rod-shaped component 1 are interconnected. The power input or output end of the wire 4 can be exposed on the exterior of the rod-shaped component 1.

[0034] Since the rod-shaped component 1 is assembled with the hollow tube 20, in the frame (such as Figure 4 or Figure 12), the frame is, for example, a display stand for carrying exhibit equipment. If a light-emitting unit is required to be disposed within a hollow tube 20 having at least a portion thereof having a light-transmitting structure, the light-transmitting structure may be a light-transmitting hole 21 disposed on the hollow tube 20. The hollow tube 20 may also be made of a light-transmitting material, or may be composed of a non-light-transmitting portion made of a non-light-transmitting material and a light-transmitting portion made of a light-transmitting material. For example, the non-light-transmitting portion may be a hollow tube body, with an elongated hole disposed in the hollow tube body. The light-transmitting portion cooperates with the elongated hole and is connected to the hollow tube body. The light-emitting unit requires power to illuminate. Since the rod-shaped component 1 in the prior art often cannot accommodate wires, even if a light-emitting unit is disposed within the hollow tube 20, the light-emitting unit cannot be used due to the lack of power supply. Therefore, a common practice is to arrange both the wires and the light-emitting unit outside the display stand, such as by mounting a spotlight on the display stand. These methods not only require additional installation space but are also unsightly.

[0035] In the present invention, a second mounting hole 5 for assembling the wire 4 is innovatively provided on the rod-shaped component 1 of the corner connector. Since a second mounting hole 5 is provided on each first mounting surface 2, multiple second mounting holes 5 are arranged around the first mounting hole 3 on each first mounting surface 2. When any first mounting surfaces 2 on any two rod-shaped components 1 are matched, the second mounting holes 5 on the two first mounting surfaces 2 correspond to each other, that is, the axial directions of the second mounting holes 5 on the two first mounting surfaces 2 are located on the same straight line. Therefore, even if multiple rod-shaped components 1 are spliced ​​into a straight line, an L-shaped or other shaped structure, since the second mounting holes 5 on the two rod-shaped components 1 are connected after the two rod-shaped components 1 are spliced, the wire 4 can still be matched with the second mounting hole 5 on each rod-shaped component 1 according to the required routing path (the straight line path can be straight line or L-shaped). For example, the wire 4 is bent so that the wire 4 adapts to the required routing path, so that the wire can be extended into the hollow tube 20 and connected to the light-emitting unit, and the light-emitting unit is lit after power is turned on. If the display rack has multiple layers, the provision of the second mounting holes 5 creates space for the wires 4 through the hollow tube 20 and the rod-shaped member 1, allowing the wires 4 to be routed along each layer of the display rack. Thus, the present invention eliminates the need for additional installation space for the light-emitting units, reducing the floor space and cost of the exhibition venue. Furthermore, there are no complex exposed wiring, thereby improving both safety and aesthetics.

[0036] In order to better arrange the wires, a third mounting hole 6 is also provided on the rod-shaped component 1. The third mounting hole 6 allows at least a portion of the first mounting hole 3 and the second mounting hole 5 to pass through, so that the power supply input end of the wire 4 can be arranged in one first mounting hole 3 and the power supply output end can be arranged in the other first mounting hole 3.

[0037] Preferably, the present invention further comprises a conductive socket 7 , which cooperates with the first mounting hole 3 , the wire 4 is connected to the conductive socket 7 , and the wire 4 cooperates with the first mounting hole 3 , the second mounting hole 5 , and the third mounting hole 6 respectively.

[0038] For example, in an L-shaped corner connector composed of two rod-shaped components 1, the power input end of the wire 4 is located in the first mounting hole 3 on the first rod-shaped component 1 and connected to the conductive socket 7. The conductive socket 7 cooperates with the first mounting hole 3 on the first rod-shaped component 1. The wire 4 passes through the third mounting hole 6 and the second mounting hole 5 of the first rod-shaped component 1, enters the second mounting hole 5 on the second rod-shaped component 1, and after being arranged according to the required routing path, passes through the third mounting hole 6 on the second rod-shaped component 1 and enters the first mounting hole 3 on the second rod-shaped component 1. Thus, after providing the third mounting hole 6, it is possible to more flexibly choose to arrange the power input or output end of the wire 4 in an appropriate position.

[0039] The present invention further includes a second connecting screw 11 and a third mounting hole 6 that is a threaded hole. The second connecting screw 11 is used to threadably connect with the third mounting hole 6. In the present invention, there are multiple third mounting holes 6, at least one of which is used to allow the wire 4 to pass through. When the hollow tube 20 is sleeved on the rod-shaped component 1, radial mounting holes are provided on the hollow tube 20. The second connecting screw 11 passes through the radial mounting holes on the hollow tube 20 and is threadably connected with another third mounting hole 6 on the rod-shaped component 1, thereby fixing the second rod-shaped component 1 and the hollow tube 20 as a whole to prevent relative displacement between the rod-shaped component 1 and the hollow tube 20.

[0040] The axial direction of the third mounting hole 6 is not parallel to the axial direction of any of the first mounting holes 3, and a portion of the opening of the third mounting hole 6 is respectively formed on two adjacent first mounting surfaces 2. The advantage of this structure is that it facilitates the third mounting hole 6 to penetrate the first mounting hole 3 and the second mounting hole 5 by the shortest distance, thereby minimizing the material removal required to form the third mounting hole 6 in the rod-shaped component 1 and maximizing the strength of the rod-shaped component 1.

[0041] In addition, since the axial direction of the third mounting hole 6 is not parallel to the axial direction of any of the first mounting holes 3, the angle formed by the axial direction of the third mounting hole 6 and the height L1 of the rod-shaped component 1 can be 30°, 45°, 60°, etc. In the present invention, the angle formed by the axial direction of the third mounting hole 6 and the length L0 or height L1 or width L2 of the rod-shaped component 1 is preferably 45°. In this way, the axis of the third mounting hole 6 passes through the two side edges of the rectangular rod-shaped component 1 that are opposite to each other at a 45-degree angle. After the rod-shaped component 1 is subsequently connected to the hollow tube 20 to form a frame, the second connecting screws 11 can be directed toward the inside of the frame, which is not only beautiful, but also makes the installation positions of the second connecting screws 11 and the hollow tube 20 uniform, which can save installation time. If the third mounting hole 6 is formed by machining after the rod-shaped component 1 is formed, the hole can be drilled along a 45° angle starting from the first side edge of the rectangular rod-shaped component 1 during machining, and the drill bit finally passes through the second side edge opposite to the first side edge. Therefore, the axial arrangement of the third mounting hole 6 at a 45° inclination has the advantage of convenient machining.

[0042] When any first mounting surfaces 2 on any two rod-shaped components 1 are mated, if the first connecting screw 10 is directly connected to the threaded holes on the two rod-shaped components 1, one of the two rod-shaped components 1 may rotate. When the first connecting screw 10 tightens the two rod-shaped components 1 into one, the two rod-shaped components 1 cannot be aligned, resulting in the axial directions of the second mounting holes 5 on the mating first mounting surfaces 2 of the two rod-shaped components 1 not being in the same straight line.

[0043] To address the issue of one of the two rod-shaped components 1 rotating during installation, the present invention further includes a positioning component 8. After any first mounting surfaces 2 on any two rod-shaped components 1 are mated, the positioning component 8 is inserted into the second mounting holes 5 on the two adjacent rod-shaped components 1 with the aid of the second mounting holes 5 before being threadedly connected to the first mounting holes 3 on the two rod-shaped components 1 via the first connecting screw 10. The positioning component 8 pre-locks the two mating rod-shaped components 1, preventing one of the rod-shaped components 1 from rotating when torque is applied to the first connecting screw 10. When the two rod-shaped components 1 are tightened, the axial directions of the second mounting holes 5 on the mating first mounting surfaces 2 of the two rod-shaped components 1 are aligned. After the two rod-shaped components 1 are tightened, the positioning component 8 can be removed from the second mounting holes 5 to prevent the positioning component 8 from interfering with the routing of the subsequent wires 4.
