Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, and in particular relates to an aluminum profile that is easy to lock and position. Background Technology

[0002] In fields such as industrial manufacturing, furniture construction, exhibition display racks, and automated equipment frames, aluminum profiles have become a core structural material to replace traditional steel due to their lightweight, corrosion resistance, and ease of processing. The convenience and stability of their splicing and assembly directly determine the production efficiency, structural strength, and service life of the end products.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: current mainstream aluminum profile splicing methods mostly rely on external corner brackets, bolt assemblies, or welding processes for fixing, which have obvious technical pain points. First, the positioning accuracy is low. Traditional aluminum profiles and connectors are mostly "surface contact + external locking" without built-in guide and limiting structures. During assembly, it is necessary to repeatedly adjust the angle and position to align the bolt holes, which is time-consuming and prone to causing the frame to tilt due to deviation, affecting the flatness.

[0004] Secondly, the locking stability is insufficient, relying solely on bolts or clips. Affected by vibration, temperature changes, etc., it is prone to loosening and falling off after long-term use, which may cause structural failure under load and pose a safety hazard.

[0005] Therefore, we propose an aluminum profile that is easy to lock and position, which can solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing an aluminum profile that is easy to lock and position, achieving precise positioning and stable locking.

[0007] In view of this, the present invention provides an aluminum profile that is easy to lock and position, including a connecting frame and an aluminum profile body. The connecting frame has a main groove through the middle of the top and bottom ends. The connecting frame has secondary grooves on the front, rear, left and right sides for splicing vertical and horizontal aluminum profile bodies. The inner walls of the front, rear, left and right sides of the main groove have a first limiting block integrally formed in the middle. The inner walls of the left and right sides of the secondary groove have a second limiting block integrally formed in the middle.

[0008] The first and second limiting blocks are equipped with a fixing mechanism inside for fixing the vertical aluminum profile body and the horizontal aluminum profile body to the connecting frame.

[0009] Furthermore, the fixing mechanism includes bolts and fixing pins for fixing the connecting frame and the aluminum profile body. Limiting grooves are provided in the middle of the front, rear, left and right sides of the aluminum profile body. The first limiting block is slidably connected to the limiting groove on the outside of the vertical aluminum profile body, and the second limiting block is slidably connected to the limiting groove on the outside of the horizontal aluminum profile body.

[0010] Furthermore, both the first limiting block and the second limiting block have horizontally opened fixing grooves in the middle of the side away from the connecting frame, and the connecting frame is fixedly connected to the aluminum profile body by bolts passing through the fixing grooves.

[0011] Furthermore, control slots are symmetrically provided on both sides of the fixing slot, and a control block is slidably connected to the inner side of the control slot. A wedge block is fixedly installed on the side of the control block near the fixing slot, the inclined surface of the wedge block is placed inside the fixing slot, and one end of the bolt is slidably connected to the inclined surface of the wedge block.

[0012] Furthermore, the fixing pin is fixedly installed on the side of the control block away from the wedge block, and the end of the fixing pin away from the control block passes through the inner wall of the limiting groove and is fixedly connected to the aluminum profile body.

[0013] Furthermore, a spring is provided on the side of the control block away from the wedge block, the spring is sleeved on the outside of the fixing pin, and the control groove is matched with the dimensions of the fixing pin and the wedge block.

[0014] The beneficial effects of this utility model are:

[0015] 1. The main channel is used to support the vertical aluminum profile body, while the secondary channel is adapted to the horizontal aluminum profile body, simultaneously meeting the requirements for cross-joining of horizontal and vertical aluminum profiles. To prevent the aluminum profiles from shifting or wobbling during the splicing process, the first limiting blocks on the front, back, left, and right inner walls of the main channel, and the second limiting blocks in the middle of the left and right inner walls of the secondary channel, can be embedded into the corresponding structures of the aluminum profile body, forming preliminary limiting constraints to prevent lateral displacement of the aluminum profile during splicing. The fixing mechanisms built into the first and second limiting blocks can further apply locking force on the basis of preliminary limiting, firmly fixing the vertical and horizontal aluminum profile bodies to the connecting frame, ultimately achieving stable positioning of the aluminum profiles after splicing and preventing loosening.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1 to 3 An aluminum profile for easy locking and positioning includes a connecting frame 1 and an aluminum profile body 15. The connecting frame 1 has a main groove 11 extending through the middle of its top and bottom ends. The connecting frame 1 also has secondary grooves 12 on its front, rear, left, and right sides for splicing vertical and horizontal aluminum profile bodies 15. The inner walls of the main groove 11 on its front, rear, left, and right sides are integrally formed with a first limiting block 13, and the inner walls of the secondary grooves 12 on both sides are integrally formed with a second limiting block 14. The first limiting block 13 and the second limiting block 14 are provided with a fixing mechanism for the fixed connection between the vertical and horizontal aluminum profile bodies 15 and the connecting frame 1.

[0023] In this technical solution, the main groove 11 is used to support the vertical aluminum profile body 15, while the secondary groove 12 is adapted to the horizontal aluminum profile body 15, thus simultaneously meeting the requirements for cross-splitting of horizontal and vertical aluminum profiles. To prevent the aluminum profiles from shifting or wobbling during splicing, the first limiting blocks 13 on the front, rear, left, and right inner walls of the main groove 11, and the second limiting blocks 14 in the middle of the left and right inner walls of the secondary groove 12, can be embedded into the corresponding structures of the aluminum profile body 15, forming preliminary limiting constraints to prevent lateral displacement of the aluminum profiles during splicing. The fixing mechanisms built into the first limiting blocks 13 and the second limiting blocks 14 can further apply locking force on the basis of preliminary limiting, firmly fixing the vertical and horizontal aluminum profile bodies 15 to the connecting frame 1, ultimately achieving stable positioning of the aluminum profiles after splicing and preventing loosening.

[0024] In this embodiment, the fixing mechanism includes bolts 26 and fixing pins 24 for fixing the connecting frame 1 and the aluminum profile body 15. Limiting grooves 16 are provided in the middle of the front, rear, left and right sides of the aluminum profile body 15. The first limiting block 13 is slidably connected to the limiting groove 16 on the outside of the vertical aluminum profile body 15, and the second limiting block 14 is slidably connected to the limiting groove 16 on the outside of the horizontal aluminum profile body 15.

[0025] In this technical solution, the front, rear, left, and right center of the aluminum profile body 15 are all provided with limiting grooves 16 that are adapted to the limiting blocks. When the vertical aluminum profile body 15 is inserted into the main groove 11 of the connecting frame 1, the first limiting block 13 in the main groove 11 will slide precisely into the limiting groove 16 of the vertical aluminum profile body 15, forming a vertical sliding guide and initial limiting. Similarly, when the horizontal aluminum profile body 15 is inserted into the secondary groove 12, the second limiting block 14 in the secondary groove 12 will embed into the limiting groove 16 of the horizontal aluminum profile body 15, completing the initial positioning in the horizontal direction. Through the sliding fit structure of "limiting block + limiting groove 16", not only can the installation position of the aluminum profile and the connecting frame 1 be quickly aligned, reducing splicing deviation, but also a stable benchmark can be provided for subsequent fixing. Subsequently, through the synergistic action of bolt 26 and fixing pin 24, the "sliding fit" between aluminum profile body 15 and connecting frame 1 can be transformed into "rigid fixation", ensuring the stability of the overall structure after splicing and preventing the aluminum profile from shifting or falling off during use.

[0026] In this embodiment, the first limiting block 13 and the second limiting block 14 are both horizontally provided with fixing grooves 2 in the middle of the side away from the connecting frame 1. The connecting frame 1 is fixedly connected to the aluminum profile body 15 by bolts 26 passing through the fixing grooves 2.

[0027] In this technical solution, after the aluminum profile body 15 is initially positioned by the "limiting block + limiting groove 16", the bolt 26 can be inserted from one end of the fixing groove 2, passing through the corresponding preset mounting holes of the limiting block and the aluminum profile body 15 in sequence, and finally locked by the nut (or screwed into the internal thread hole of the aluminum profile body 15). The locking force of the bolt 26 will directly act on the contact surface between the connecting frame 1 and the aluminum profile body 15, tightly fitting the two together and forming a fastening force along the axial direction of the bolt 26, effectively preventing axial loosening between the aluminum profile and the connecting frame 1, laying the foundation for further reinforcement.

[0028] In this embodiment, control grooves 21 are symmetrically provided on both sides of the fixing groove 2. A control block 22 is slidably connected to the inner side of the control groove 21. A wedge block 23 is fixedly installed on the side of the control block 22 near the fixing groove 2. The inclined surface of the wedge block 23 is placed inside the fixing groove 2, and one end of the bolt 26 is slidably connected to the inclined surface of the wedge block 23.

[0029] In this technical solution, a wedge-shaped block 23 is fixed to the side of the control block 22 near the fixing groove 2, with its inclined surface facing inwards from the fixing groove 2 and forming a sliding fit with the end of the bolt 26. When the bolt 26 is screwed into the aluminum profile body 15 along the fixing groove 2, the end of the bolt 26 gradually presses against the inclined surface of the wedge-shaped block 23. Due to the guiding effect of the inclined surface, the axial pressure of the bolt 26 is converted into a lateral force that pushes the wedge-shaped block 23 to move outwards from the control groove 21. Under the action of this lateral force, the control block 22 slides outwards along the control groove 21 synchronously with the wedge-shaped block 23, preparing for the extension of the fixing pin 24, thus realizing the automated linkage of "bolt 26 screwing in - wedge-shaped block 23 inclined surface being stressed - control block 22 sliding".

[0030] In this embodiment, the fixing pin 24 is fixedly installed on the side of the control block 22 away from the wedge block 23, and the end of the fixing pin 24 away from the control block 22 passes through the inner wall of the limiting groove 16 and is fixedly connected to the aluminum profile body 15.

[0031] In this technical solution, when the control block 22 slides outward along the control groove 21 under the action of lateral force, it simultaneously drives the fixing pin 24 to move towards the aluminum profile body 15. Ultimately, the end of the fixing pin 24 away from the control block 22 moves out of the control groove 21 and inserts into the inner wall of the limiting groove 16 for fixation. At this time, the fixing pin 24 forms a limiting constraint on the aluminum profile body 15 in the horizontal direction, complementing the axial fixation of the bolt 26, preventing lateral displacement and rotation between the aluminum profile body 15 and the connecting frame 1, and significantly improving the overall stability of the connection.

[0032] In this embodiment, a spring 25 is provided on the side of the control block 22 away from the wedge block 23. The spring 25 is sleeved on the outside of the fixing pin 24, and the control groove 21 matches the size of the fixing pin 24 and the wedge block 23.

[0033] In this technical solution, when in the natural state, the spring 25 applies a preload force to the control block 22 in the direction of the fixing groove 2, so that the inclined surface of the wedge block 23 is always kept in the preset position in the fixing groove 2, which facilitates the precise contact of the bolt 26 end. At the same time, the control block 22 can pull the fixing pin 24 into the control groove 21, so as to avoid the fixing pin 24 interfering with the sliding of the limiting block in the limiting groove 16.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
