Description

Technical Field

[0001] This application relates to the technical field of aluminum profile connection, and particularly to a connecting piece for aluminum profiles. Background Art

[0002] Aluminum profiles are aluminum materials obtained by melting and extruding aluminum bars to obtain different cross-sectional shapes. Aluminum profiles have many advantages such as light weight, excellent forming, high strength, corrosion resistance, long life, and recyclability. Due to these excellent characteristics of aluminum profiles, with the large-scale infrastructure investment and the rapid advancement of the industrialization process in China, the production and consumption of the entire aluminum profile industry have increased rapidly, and China has also become the world's largest aluminum profile production base and consumption market.

[0003] As Figure 1 shown in the aluminum profile 1, generally a strip-shaped groove 2 is provided along the length direction of the aluminum profile 1, and a guiding strip 3 is fixedly connected to the aluminum profile 1 along its length direction, and the guiding strip 3 is located in the strip-shaped groove 2. Currently, during the use of aluminum profiles, in order to connect aluminum profiles to each other or to other mechanical components, connecting pieces are usually required, and the rotational connection of two aluminum profiles is realized by relying on the connecting pieces.

[0004] In the prior art, usually a bearing assembly is arranged between two profiles, and the relative rotation of two aluminum profiles is carried out through the bearing assembly.

[0005] Regarding the above related technology, when using the bearing assembly to connect two aluminum profiles, the disassembly and assembly of the two profiles are relatively troublesome, increasing the workload of the operator, so there is room for improvement. Utility Model Content

[0006] In order to facilitate the connection of two aluminum profiles, this application provides a connecting piece for aluminum profiles.

[0007] The connecting piece for aluminum profiles provided by this application adopts the following technical solution:

[0008] A connecting piece for aluminum profiles includes a nut block, a fastening member, and a rotating piece. The nut block is installed in one of the profiles. One end of the fastening member passes through the rotating piece and is locked to the nut block. An installation hole for connecting the fastening member is provided on the nut block;

[0009] A through hole for the fastening member to pass through is provided on the rotating piece. The cross-section of the through hole gradually decreases in the direction close to the nut block. A convex platform is connected to the end of the fastening member far from the nut block. The cross-section of the convex platform gradually decreases in the direction close to the nut block. The convex platform is arranged in the through hole, and the rotating piece is rotatably connected to the fastening member;

[0010] Wherein, a clamping block is connected to one side of the rotating piece away from the nut block, and the clamping block is clamped in another profile.

[0011] By adopting the above technical solution, during installation, first place the nut block in the strip groove of one of the profiles, then pass the fastener through the rotating piece and lock the fastener in the mounting hole of the nut block, and then snap the other profile onto the clamping block on the rotating piece. After the installation is completed, there is still a certain space between the profile where the rotating piece and the nut block are located, enabling the rotating piece to rotate, thereby driving the profile on the rotating piece and the other profile to rotate relative to each other, realizing the rotational connection between the two profiles. The entire connection method is relatively simple, convenient for the operator to disassemble and assemble, and has good stability.

[0012] Preferably, the fastener is a fastening bolt or a fastening stud, and the fastening bolt or the fastening stud is screwed onto the nut block.

[0013] By adopting the above technical solution, the fastening bolt or the fastening stud is installed on the nut block by screwing, realizing the detachable connection between the fastener and the nut block.

[0014] Preferably, a gasket is further included. The fastener sequentially passes through the rotating piece and the gasket. The gasket is located between the rotating piece and the nut block, and the gasket abuts against the profile.

[0015] By adopting the above technical solution, the gasket abuts against the surface of the profile where the nut block is located, and the gasket replaces the contact between the rotating piece and the profile, reducing the contact area between the rotating piece and the profile, and improving the smoothness of the rotating piece during rotation.

[0016] Preferably, a ball head spring is further included. The ball head spring is arranged on the side of the nut block away from the rotating piece, and the ball head spring is used to abut in the strip groove of the profile.

[0017] By adopting the above technical solution, when the fastener locks the nut block in the strip groove of the profile, the ball head spring is elastically deformed and compressed under the external force. Under the elastic reaction force, the ball head spring will exert a pressure on the profile, increasing the static friction between the nut block and the profile, making the nut block more stable during the installation process, and reducing the probability of the nut block slipping.

[0018] Preferably, a guiding groove is further opened on the nut block, and the guiding groove is used for the guiding strip of the profile to be clamped.

[0019] By adopting the above technical solution, after the nut block is placed in the strip groove, the user can apply thrust to the nut block to make the nut block slide horizontally in the strip groove, thereby adjusting the relative position of the nut block and the profile according to actual needs. With the cooperation of the guide groove and the guide strip, the stability of the nut block when moving can be improved.

[0020] Preferably, it also includes a torsion spring and a wedge block, the torsion spring is connected to the clamping block, the wedge block is rotatably connected to the clamping block via the torsion spring, the wedge surface of the wedge block is inclined downward in a direction close to the rotating piece; and a clearance groove for accommodating the wedge block is provided on the clamping block.

[0021] By adopting the above technical solution, when the profile is gradually inserted into the clamping block from top to bottom, the guide bar of the profile will first contact the wedge block and squeeze the wedge block, so that the wedge block rotates and enters the clearance groove. When the clamping block is completely inserted into the strip groove, the wedge block rotates and resets under the action of the torsion spring. At this time, the wedge block will have a certain blocking effect on the profile, reducing the possibility of the profile detaching from the clamping block.

[0022] Preferably, the outer surface of the block is provided with friction lines.

[0023] By adopting the above technical solution, the friction lines can increase the roughness of the outer surface of the block, thereby increasing the contact static friction. When the profile is clamped on the block, the firmness of the connection between the profile and the block can be improved.

[0024] Preferably, outer surfaces of the rotating plate and the nut block are coated with a paint layer.

[0025] By adopting the above technical solution, the paint layer can increase the aesthetics of the rotating piece and the nut block on the one hand, and can improve the corrosion resistance of the two and extend the service life on the other hand.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] (1) By setting a nut block, a fastener and a rotating plate, the nut block is placed in the strip groove of one of the profiles, and then the fastener is passed through the rotating plate and locked on the mounting hole of the nut block, and then another profile is clamped on the clamping block on the rotating plate. After the installation is completed, there is still a certain space between the rotating plate and the profile where the nut block is located, so that the rotating plate can rotate, thereby realizing the rotation connection between the two profiles.

[0028] (2) By setting a gasket or a block to replace the contact between the rotating plate and the profile, the contact area between the rotating plate and the profile is reduced, thereby improving the smoothness of the rotating plate during rotation.

[0029] (3) By setting the torsion spring and the wedge block, after the clamping block is clamped into the profile, the wedge block will have a certain blocking effect on the profile, reducing the possibility of the profile disengaging from the clamping block. Description of the Drawings

For example, it can be a fixed connection; it can also be a detachable connection; or integrated; it can also be a mechanical connection. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0041] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, those skilled in the art can combine and combine different embodiments or examples represented in the present application and the features of different embodiments or examples.

[0042] The embodiments of the present application disclose a connecting piece for aluminum profiles. Refer to Figure 2 and Figure 3 , the connecting piece includes a nut block 4, a fastener 5 and a rotating piece 6. The nut block 4 is slidably connected in one of the profiles. A guiding groove 7 is formed on the surface of the nut block 4 for engaging with the guiding strip of the profile. As shown in the figure, in this embodiment, the number of guiding grooves 7 is two, and the two guiding grooves 7 are parallel to each other. After the nut block 4 is placed into the strip-shaped groove, the user can apply a thrust to the nut block 4 so that the nut block 4 slides horizontally in the strip-shaped groove, thereby adjusting the relative position of the nut block 4 and the profile according to actual needs. With the mutual cooperation of the guiding groove 7 and the guiding strip, the smoothness of the movement of the nut block 4 can be improved.

[0043] Combined with Figure 4 , one end of the fastener 5 passes through the rotating piece 6 and is locked on the nut block 4. An installation hole 8 for connecting the fastener 5 is formed on the nut block 4. In this embodiment, the fastener 5 is a detachable object such as a fastening bolt or a fastening stud, and the fastening bolt or the fastening stud is screwed into the installation hole 8 of the nut block 4. Among them, paint layers are coated on the outer surfaces of the rotating piece 6 and the nut block 4. The paint layer can be, but is not limited to, a metal layer, a non-metal layer and a chemical layer. On the one hand, the paint layer can increase the aesthetics of the rotating piece 6 and the nut block 4, and on the other hand, it can improve the anti-corrosion ability of the two and extend the service life.

[0044] Specifically, a through hole 9 for the fastener 5 to pass through is formed on the rotating piece 6. The through hole 9 is a round hole, and the cross-section of the through hole 9 gradually decreases in the direction close to the nut block 4. A boss 10 is integrally connected to the end of the fastener 5 away from the nut block 4. The cross-section of the boss 10 is circular, and the cross-section diameter gradually decreases in the direction close to the nut block 4. After the fastener 5 passes through the rotating piece 6 and is locked on the nut block 4, the boss 10 is located in the through hole 9; at the same time, the rotating piece 6 is rotatably connected to the fastener 5, and the rotating piece 6 rotates around the fastener 5 as the axis.

[0045] Wherein, on one side of the rotating piece 6 away from the nut block 4, a plurality of clamping blocks 11 are fixedly connected. The clamping blocks 11 are distributed at intervals and are all used for clamping in another profile. In some embodiments, friction lines are further provided on the outer surface of the clamping block 11. The friction lines can increase the roughness of the outer surface of the clamping block 11, thereby increasing the static friction force between the clamping block 11 and the profile and improving the firmness of the connection between the profile and the clamping block 11.

[0046] Combined Figure 5 , during installation, first place the nut block 4 in the strip groove of one profile, then pass the fastener 5 through the rotating piece 6 and lock the fastener 5 in the mounting hole 8 of the nut block 4, and then clamp another profile on the clamping block 11 on the rotating piece 6. After the installation is completed, there is still a certain space between the profile where the rotating piece 6 and the nut block 4 are located, so that the rotating piece 6 can rotate, thereby driving the profile on the rotating piece 6 and another profile to rotate relative to each other, realizing the rotational connection between the two profiles. The whole connection method is relatively simple, the operator is convenient to disassemble and assemble, and the stability is relatively good.

[0047] In addition, a gasket 12 is sleeved on the fastener 5. One end of the fastener 5 passes through the rotating piece 6 and the gasket 12 in sequence, so that the gasket 12 is located between the rotating piece 6 and the nut block 4. The gasket 12 is used to abut against the profile where the nut block 4 is located. The cushion block contacts the profile instead of the rotating piece 6, and by reducing the contact area between the rotating piece 6 and the profile, the smoothness of the rotating piece 6 during rotation is improved.

[0048] On the side of the nut block 4 away from the rotating piece 6, a ball head spring 13 is further connected. The ball head spring 13 is used to abut against the strip groove of the profile. When the fastener 5 locks the nut block 4 in the strip groove of the profile, the ball head spring 13 is elastically deformed and compressed under the external force. Under the elastic reaction force, the ball head spring 13 will generate a pressure on the profile, increasing the static friction force between the nut block 4 and the profile, making the nut block 4 relatively stable during the installation process and reducing the probability of the nut block 4 slipping.

[0049] In some embodiments, please refer to Figure 6 , a wedge block 14 is also rotatably connected to the clamping block 11. The wedge block 14 is rotatably connected to the clamping block 11 through a torsion spring; the wedge surface of the wedge block 14 is inclined downward along the direction close to the rotating piece 6, and a relief groove for accommodating the wedge block 14 is provided on the clamping block 11. As shown in the figure, the number of wedge blocks 14 is two, and the two wedge blocks 14 are symmetrically distributed on the clamping block 11.

[0050] When the profile is gradually inserted into the clamping block 11 from top to bottom, the guide bar of the profile will first contact the wedge block 14 and squeeze the wedge block 14, causing the wedge block 14 to rotate and enter the clearance groove. When the clamping block 11 is completely inserted into the strip groove, the wedge block 14 rotates and resets under the action of the torsion spring. At this time, the wedge block 14 will have a certain blocking effect on the profile, reducing the possibility of the profile escaping from the clamping block 11.

[0051] The implementation principle of a connector for aluminum profiles in the embodiment of the present application is as follows: during installation, first place the nut block 4 in the strip groove of one of the profiles, then pass the fastener 5 through the rotating plate 6 and the gasket 12 in sequence, and lock the fastener 5 on the mounting hole 8 of the nut block 4, and then clamp the other profile on the clamping block 11 on the rotating plate 6. After the installation is completed, there is still a certain space between the rotating plate 6 and the profile where the nut block 4 is located, so that the rotating plate 6 can rotate, thereby driving the profile on the rotating plate 6 and the other profile to rotate relative to each other, thereby realizing the rotation connection between the two profiles. The entire connection method is relatively simple, and it is relatively convenient for operators to disassemble and assemble, and it has good stability.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
