Description

Corner connection structure Technical Field

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

[0002] Traditionally, corner connectors are used to connect adjacent profiles at corners. These corner connectors have perpendicular connecting sections, and both the connecting sections and the profiles have threaded holes or through holes. They are then fixed with screws or bolts. This requires tools for installation, which is inconvenient, time-consuming, and unsightly.

[0003] Currently, adapters on the market have elastic bosses installed on the connecting end surface. These bosses snap into holes at the ends of the profiles to connect adjacent profiles without the need for tools. However, there is an elastic body between the elastic boss and the connecting end surface. Holding down the elastic boss during insertion and removal can easily cause cuts to the operator's hands, and the elastic body is not fixed, making it easy to damage the elastic boss. Furthermore, since the elastic boss is located on the adapter, it can also be damaged during transportation. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] Example 1

[0029] As shown in Figures 1 and 2, a corner connection structure includes a first profile 1, a second profile 2, and a corner connector 3. Connecting buckles 4 are respectively installed in the profile through holes near the two ends of the first profile 1 and the second profile 2. The corner connector 3 includes a first connecting section 31 and a second connecting section 32 that are connected to each other. The first profile 1 is sleeved on the first connecting section 31, and the second profile 2 is sleeved on the second connecting section 32. Both the first connecting section 31 and the second connecting section 32 are provided with locking holes 30 that cooperate with the connecting buckles 4 near their ends.

[0030] As shown in Figure 3, the connecting buckle 4 includes a fastener body 41 that mates with the inner contour of the through hole in the profile. A notch 43 is provided on one side of the fastener body 41, and a spring piece 42 is provided at the notch 43. One end of the spring piece 42 is connected to the fastener body 41, and the other end has a barb portion 421 that mates with the locking hole 30. More specifically, a first connecting hole 411 is provided on the fastener body 41, and a protrusion 422 is provided on the spring piece 42. In this embodiment, the protrusion 422 is preferably cylindrical, mainly considering the ease of machining holes on the profile that mate with the protrusion 422.

[0031] As shown in Figure 4, the corner connector 3 also includes an intermediate connecting section 33, which connects the first connecting section 31 and the second connecting section 32. The first connecting section 31, the intermediate connecting section 33, and the second connecting section 32 are integrally formed. The intermediate connecting section 33 includes a first connecting block 331 and a second connecting block 332. The first connecting block 331 is connected to the first connecting section 31, and the second connecting block 332 is connected to the second connecting section 32. In this embodiment, the included angle between the first connecting block 331 and the second connecting block 332 is 90°, meaning the intermediate connecting section 33 is L-shaped.

[0032] As shown in Figure 2, both the first profile 1 and the second profile 2 have locking holes 10 that mate with the protrusion 422. Both the first profile 1 and the second profile 2 have second connecting holes 20. The first profile 1 and the connecting buckle 4, and the second profile 2 and the connecting buckle 4 are connected by rivets that pass through the second connecting hole 20 and the first connecting hole 411 in sequence.

[0033] During installation, first push the connecting buckle 4 into the through hole of the profile at one end. The inner wall of the profile presses the protrusion 422 on the connecting buckle 4, causing the spring piece 42 to deform slightly until the protrusion 422 reaches the locking hole 10 and extends out. The spring piece 42 then returns to its original position. Connect the connecting buckle 4 to the profile with rivets, and then install the connecting buckle 4 at the other end of the profile. After both profiles have the connecting buckles 4 installed, insert one end of the profile into the connecting section at one end of the corner connector 3. At this time, the barb part 421 of the connecting buckle 4 hooks into the locking hole 30 of the connecting section, and the profile and the corner connector 3 are locked together.

[0034] Compared to existing patents, the connecting buckle 4 in this embodiment is fixed inside the profile and does not move, which is safer for the operator; and the corner connector 3 is a separate part, and there is no elastic boss on the corner connector 3, so the parts will not be damaged during transportation.

[0035] Example 2

[0036] As shown in Figure 5, the difference from Embodiment 1 is that the included angle between the first connecting block 331 and the second connecting block 332 of the middle connecting segment 33 on the corner connector 3 in this embodiment is 100°, that is, the middle connecting segment 33 is a straight strip structure.

[0037] Example 3

[0038] As shown in Figure 6, the difference from Embodiment 1 is that the included angle between the first connecting block 331 and the second connecting block 332 of the middle connecting segment 33 on the corner connector 3 in this embodiment is 180°.

[0039] Of course, depending on actual needs, the included angle between the first connecting block 331 and the second connecting block 332 of the middle connecting section 33 on the corner connector 3 can be any angle between 0 and 180°.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
