Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an adjustable angle aluminum profile corner connector. Background Technology

[0002] In modern industrial manufacturing, building decoration and various equipment assembly fields, aluminum profiles are widely used to construct various frame structures due to their many excellent properties such as light weight, high strength, corrosion resistance and easy processing. The connection between aluminum profiles is the key link to realize these frame structures, among which corner connections are particularly common.

[0003] Currently, there are various types of aluminum profile corner connectors on the market. Common traditional connectors are mainly designed to connect three mutually perpendicular aluminum profiles. This standard right-angle connection method performs well in many regular frame construction scenarios, such as common rectangular equipment shell frames, standard building interior door and window frame frames, etc. It can meet the needs of most conventional structural designs, and its structure is relatively simple, the installation process is relatively mature, and the cost is relatively controllable.

[0004] However, in practical applications, engineering scenarios are often complex and diverse. Not all structural designs are limited to right-angle connections. When encountering a connection requirement where one of the three aluminum profiles is not perpendicular to the other two, the existing conventional connectors reveal obvious limitations. In such a non-perpendicular connection, if traditional connectors are still used, at least two connectors are usually required for combination connection.

[0005] For example, in the construction of some irregularly shaped display racks, architectural decoration structures with special shape requirements, and some mechanical tooling equipment frames that require flexible angle adjustment, the use of multiple traditional connectors not only increases material costs, but also makes the connection structure more complex and cumbersome. During the installation process, it is necessary to accurately calculate the position and angle of multiple connectors, which greatly increases the installation difficulty and construction time. At the same time, the use of too many connectors may reduce the stability and aesthetics of the entire structure.

[0006] In conclusion, there is an urgent practical need to develop a new type of connector that can conveniently, quickly, and accurately change the connection angle to accommodate the connection of three non-perpendicular aluminum profiles. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable-angle aluminum profile corner connector that can conveniently and accurately change the connection angle and is compatible with the connection of three non-perpendicular aluminum profiles, thereby reducing the number of connectors used and lowering material costs.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] An adjustable angle aluminum profile corner connector includes a connecting body, wherein a first connecting strip is fixed on one side of the connecting body and near the upper and left ends, and a second connecting strip is rotatably connected to the right and lower ends of the connecting body.

[0010] A locking structure is installed between the connecting body and the second connecting strip.

[0011] The locking structure includes a fixing block fixed to the top and bottom of the second connecting strip and located inside the connecting body. The fixing block has multiple vertically arranged mounting slots. The connecting body has a guide slot located at the position corresponding to the mounting slot. The guide slot is elliptical and has a bolt inserted into it. The bolt is threaded to one of the mounting slots.

[0012] A first washer is provided between the bolt and the guide groove.

[0013] An installation block is inserted into the connecting body, and a locking block is fixed at both the upper and lower ends of the installation block. An installation compartment corresponding to the installation block and the locking block is provided in the second connecting strip, and the installation block and the locking block are inserted into the installation compartment.

[0014] A connector is fitted between the bolt and the mounting block.

[0015] The connector includes a retaining ring disposed on the outside of the bolt, a retaining strip fixed to the outside of the retaining ring, a connecting piece fixed to one end of the retaining strip near the locking block, and the connecting piece being attached to the locking block and connected by screws.

[0016] A second washer is provided between the bolt and the fixing strip.

[0017] A contacting protrusion is provided on one side of the connecting piece and on the outside of the card block, and the contacting protrusion is in contact with the card block.

[0018] The technical effects achieved by this utility model are as follows:

[0019] This invention allows for convenient and precise adjustment of the connection angle by rotating the second connecting strip to fit the aluminum profile and then fixing the second connecting strip. It can also accommodate the connection of three non-perpendicular aluminum profiles, thereby reducing the number of connecting parts and lowering material costs. Attached Figure Description

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figures 1-6 As shown, an adjustable-angle aluminum profile corner connector includes a connecting body 1. A first connecting strip 2 is fixed on one side of the connecting body 1, near the upper end face and the left end face. A second connecting strip 3 is rotatably connected to the right end face and the lower end face of the connecting body 1. Both the first connecting strip 2 and the second connecting strip 3 can be made of metals with high hardness and toughness, such as steel, and the surface is anodized to improve corrosion resistance and surface hardness. When connecting aluminum profiles, the ends of the three aluminum profiles are connected in three dimensions, such as quadrants XYZ. The two first connecting strips 2 are inserted into or attached to the aluminum profiles along the horizontal X and vertical Y axes, respectively, and the two second connecting strips 3 are connected to the aluminum profiles along the horizontal Z axis. The first connecting strips 2 and the second connecting strips 3 are connected to the aluminum profiles they contact with by screws, thereby enabling the three aluminum profiles to be fixedly connected.

[0030] A locking structure is installed between the connecting body 1 and the second connecting strip 3.

[0031] See attached document Figures 3-6The locking structure includes a fixing block 4 fixed to the top and bottom of the second connecting strip 3 and located inside the connecting body 1. Multiple mounting slots 5 are vertically arranged inside the fixing block 4. A guide groove 7, elliptical in shape, is provided inside the connecting body 1 at a position corresponding to each mounting slot 5. This arrangement allows the second connecting strip 3 to align with different mounting slots 5 after rotation, enabling the selection of different mounting slots 5 for subsequent bolt 6 installation. A bolt 6 is inserted into the guide groove 7 and threadedly connected to one of the mounting slots 5. A first washer 14 is provided between the bolt 6 and the guide groove 7. This arrangement ensures that when the bolt 6 is tightened, the first washer 14 and the connecting body 1... The bolt 6 is locked on the outside of the guide groove 7 and will not loosen. The first washer 14 can be a spring washer to prevent the bolt 6 from loosening. The contact surface between the head of the bolt 6 and the connecting body 1 is also provided with anti-slip teeth to further enhance the locking reliability. The guide groove 7 is elliptical, so that even if the second connecting bar 3 is subjected to external force and wants to rotate, the bolt 6 is connected to the thread in the mounting groove 5. The second connecting bar 3 will want to rotate around the central axis of rotation of the connecting body 1. However, the guide groove 7 prevents the bolt 6 from moving along the track of the guide groove 7 when it rotates. Instead, it will be stuck in the guide groove 7, thus preventing the second connecting bar 3 from rotating.

[0032] When installing certain three-dimensional aluminum profiles, if a certain axis needs to be offset by a certain angle, during installation, firstly, the first connecting strip 2 is embedded into the T-slot of the corresponding aluminum profile and pre-tightened with screws; then, the second connecting strip 3 is rotated to the target angle, and after being fixed by the locking structure, the Z-axis aluminum profile is connected to the second connecting strip 3 with screws, finally forming a three-dimensional connection at a non-perpendicular angle, thereby ensuring the stability of the second connecting strip 3;

[0033] See attached document Figure 4 - Appendix Figure 6 An installation block 8 is inserted into the connecting body 1. Both ends of the installation block 8 are fixed with a locking block 13. The second connecting strip 3 is provided with an installation compartment 12 corresponding to the installation block 8 and the locking block 13, and the installation block 8 and the locking block 13 are inserted into the installation compartment 12.

[0034] After changing the angle of the second connecting strip 3, the mounting block 8 can be inserted into the mounting chamber 12. By setting the locking block 13, the rotational potential energy of the second connecting strip 3 is further restricted, thereby ensuring the stability of the second connecting strip 3.

[0035] A connector is assembled between the bolt 6 and the mounting block 8. Further, the connector includes a retaining ring 9 disposed on the outside of the bolt 6. Further, a second washer 16 is disposed between the bolt 6 and the retaining strip 10. The second washer 16 increases the friction between the end of the bolt 6 and the retaining ring 9, preventing the retaining ring 9 from rotating. A retaining strip 10 is fixed to the outside of the retaining ring 9. A connecting piece 11 is fixed to one end of the retaining strip 10 near the locking block 13. The connecting piece 11 is attached to the locking block 13 and connected by screws. An abutting protrusion 15 is disposed on one side of the connecting piece 11 and located on the outside of the locking block 13. The abutting protrusion 15 is attached to the locking block 13. The abutting protrusion 15 can be locked on the outside of the locking block 13, locking the locking block 13.

[0036] When fixing the mounting block 8, the fixing ring 9 can be assembled on the outside of the bolt 6, and the connecting piece 11 can be in contact with the locking block 13. The mounting block 8 and the locking block 13 can be fixed by connecting the connecting piece 11 and the locking block 13 with screws, so as to prevent the mounting block 8 and the locking block 13 from falling off.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
