Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, and in particular to a reinforcing connector for aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry, and are extensively used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration and chemical industries.

[0003] Existing aluminum alloy profiles mainly rely on metal accessories such as fixing plates and triangular braces in conjunction with bolts for connection and fixation. Under long-term vibration loads, the bolts are prone to loosening and failure, resulting in displacement of the connection interface. Especially under dynamic load environments (such as rail transit and mechanical equipment), loose connections will reduce the overall structural integrity and may even cause safety accidents such as profile detachment.

[0008] Preferably, each of the four side walls of the fixed limiting frame and the movable limiting frame has two clamping through holes. Two auxiliary locking frames and two locking bolts are provided on the outer side of the fixed limiting frame and the movable limiting frame. The two auxiliary locking frames are symmetrically arranged on the front and rear sides. The rear ends of the two locking bolts pass through the side wall of the front auxiliary locking frame and are threaded to the side wall of the rear auxiliary locking frame. The ends of the two auxiliary locking frames away from the locking bolts are hinged by pins. The outer side walls of the fixed limiting frame and the movable limiting frame do not abut against the inner side walls of the two auxiliary locking frames.

[0010] Preferably, the fixed block has a limiting groove at the center of each of the five faces other than the top face. The limiting groove is a square groove, and the bottom of the limiting groove has an internal threaded connection groove.

[0012] Compared with related technologies, the aluminum alloy profile reinforcement connector provided by this utility model has the following beneficial effects:

[0013] 1. This utility model provides an aluminum alloy profile reinforcement connector. The movable limiting frame and the fixed block are connected through the mating groove and internal thread groove on the fixed block and the connecting threaded rod, thereby achieving the connection between the fixed limiting frame and the movable limiting frame. The aluminum alloy profile is connected and fixed through the fixed limiting frame and the movable limiting frame. When fixing the aluminum alloy profiles, the limiting frame and locking mechanism achieve the main fixing effect, while the auxiliary locking frame and pressing block provide auxiliary fixing of the aluminum alloy profiles, further improving the connection's firmness. Due to the setting of the fixed limiting frame and the movable limiting frame, even if the locking bolts and locking threaded rods are loose, this device still has a certain limiting effect on the aluminum alloy profiles, thus preventing the profiles from separating after the bolts loosen.

[0028] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figures 1-12 This utility model provides a technical solution: an aluminum alloy profile reinforcement connector, including a fixing block 1, the fixing block 1 is a cube structure, the upper end of the fixing block 1 is fixedly connected to an auxiliary rod 20 and a fixed limiting frame 2, the auxiliary rod 20 is located inside the fixed limiting frame 2, a movable limiting frame 3 is provided on the right side of the fixing block 1, the left inner wall of the fixed limiting frame 2 and the lower inner wall of the movable limiting frame 3 are both fixedly connected to a limiting frame 4, the limiting frame 4 has a T-shaped cross section, and a locking mechanism 5 is provided on the right side wall of the fixed limiting frame 2 and the upper side wall of the movable limiting frame 3;

[0031] The locking mechanism 5 includes a connecting pipe 7 and a pressing plate 9. The two connecting pipes 7 are respectively fixed on the right outer wall of the fixed limiting frame 2 and the upper outer wall of the movable limiting frame 3. The end of the pressing plate 9 away from the limiting frame 4 is fixedly connected to a connecting rod 10. The ends of the two connecting rods 10 away from the pressing plate 9 pass through the right side wall of the fixed limiting frame 2 and the upper side wall of the movable limiting frame 4 and are fixedly connected to a sliding plate 11. The outer side wall of the sliding plate 11 is slidably connected to the inner side wall of the connecting pipe 7. The end of the sliding plate 11 away from the connecting rod 10 is fixedly connected to a locking threaded rod 14. The end of the locking threaded rod 14 away from the sliding plate 11 extends to the outside of the connecting pipe 7 and is threadedly connected to a locking nut 15.

[0032] A limiting slide 8 is provided on the side wall of the connecting pipe 7. The limiting slide 8 is U-shaped, and the circumferential angle of the two parallel slide sections in the limiting slide 8 is 90 degrees. A limiting rod 12 is fixedly connected to the outer wall of the sliding plate 11. The end of the limiting rod 12 away from the sliding plate 11 extends into the limiting slide 8. Abutment springs 13 are sleeved on the connecting rod 10. The ends of the two abutment springs 13 away from the pressure plate 9 are fixedly connected to the ends of the sliding plate 11 near the pressure plate 9. The ends of the two abutment springs 13 near the pressure plate 9 are respectively fixedly connected to the right outer wall of the fixed limiting frame 2 and the upper outer wall of the movable limiting frame 3. When the aluminum alloy profile is not installed, the pressure plate 9 is in a direction parallel to the limiting frame 4, and the limiting rod 12 moves to one end of the limiting slide 8 under the action of the abutment springs 13. When the aluminum alloy profile is inserted, the pressure plate 9 is located in the fixing groove of the aluminum alloy profile. At the designated position, press the locking threaded rod 14 towards the aluminum alloy profile to push the clamping plate 9 into the fixing groove on the side wall of the aluminum alloy profile. Rotate the locking threaded rod 14 to drive the sliding plate 11 and the clamping plate 9 to rotate. The limiting rod 12 moves along the limiting slide 8 from one side of the limiting slide 8 to the other side. At this time, the clamping plate 9 rotates 90 degrees and is in a perpendicular position to the aluminum alloy profile. The end of the clamping plate 9 near the sliding plate 11 abuts against the inner side wall of the fixing groove of the aluminum alloy profile. At this time, the limiting rod 12 is located in the middle position of the limiting slide 8. Then rotate the locking nut 15. The locking nut 15 cooperates with the locking threaded rod 14. After the side wall of the locking nut 15 abuts against one end of the connecting pipe 7, continue to rotate. Then, the clamping plate 9 applies a force to the aluminum alloy profile away from the limiting frame 4. Thus, the aluminum alloy profile is fixed in position in cooperation with the limiting frame 4.

[0033] Two clamping through holes 6 are provided on each of the four side walls of the fixed limiting frame 2 and the movable limiting frame 3. Two auxiliary locking frames 26 and two locking bolts 27 are provided on the outer side of the fixed limiting frame 2 and the movable limiting frame 3. The two auxiliary locking frames 26 are symmetrically arranged on the front and rear sides. The rear ends of the two locking bolts 27 pass through the side wall of the front auxiliary locking frame 26 in sequence and are threadedly connected to the side wall of the rear auxiliary locking frame 26. The ends of the two auxiliary locking frames 26 away from the locking bolts 27 are hinged by pins. The outer side walls of the fixed limiting frame 2 and the movable limiting frame 3 do not abut against the inner side walls of the two auxiliary locking frames 26.

[0034] Two auxiliary locking frames 26 are fixedly connected to adjacent inner sidewalls on the front and rear sides. The end of the clamping block 28 away from the auxiliary locking frame 26 extends into the clamping through hole 6. The outer diameter of the clamping block 28 is smaller than the inner diameter of the clamping through hole 6, so as to ensure that when the two auxiliary locking frames 26 are fitted on the outside of the fixed limit frame 2 or the movable limit frame 3, they can smoothly clamp the outer sidewall of the aluminum alloy profile through the clamping through hole 6.

[0035] Limiting grooves 18 are provided at the center of each of the five faces of the fixed block 1, excluding the top face. The presence of limiting grooves 18 on each of the five faces facilitates the device's ability to be fixed in different positions and directions according to varying quantities of profiles. Through the cooperation of the mating plate 16 with the limiting grooves 18 (which are square grooves), the direction of the locking mechanism 5 can be adjusted according to actual conditions during the assembly of the movable limiting frame 3 and the fixed block 1, preventing the locking mechanism 5 from being inconvenient to operate or affecting equipment installation. An internal threaded connection groove 19 is provided at the bottom of the limiting groove 18. The left side of the movable limiting frame 3 is fixedly connected to the mating plate 16, which is adapted to the limiting groove 18. The left side wall of the movable limiting frame 3... The upper part has an operating hole 17. An auxiliary rod 24 is provided inside the movable limiting frame 3. A cross groove 25 is provided on the right end of the auxiliary rod 24. The cross groove 25 facilitates the operation of the auxiliary rod 24 to connect the threaded rod 21, thereby realizing the connection between the movable limiting frame 3 and the fixed block 1. A connecting threaded rod 21 is fixedly connected to the left end of the auxiliary rod 24. The left end of the connecting threaded rod 21 passes through the mating plate 16 and is threadedly connected to the internal threaded connecting groove 19. A clamping ring 22 is fixedly connected to the connecting threaded rod 21. The clamping ring 22 is located inside the operating hole 17. A spring washer 23 is sleeved on the connecting threaded rod 21. The spring washer 23 is located between the mating plate 16 and the clamping ring 22.

[0036] A support plate 29 is provided below the fixed block 1. A support threaded rod 30 is fixedly connected to the upper end of the support plate 29. The support threaded rod 30 is adapted to the internal threaded connecting groove 19. When it is necessary to support the equipment, the support threaded rod 30 can be used to cooperate with the internal threaded connecting groove 19 at the bottom position. The overall leveling of the device can be achieved by adjusting the position of the support threaded rod 30 and the bottom of the internal threaded connecting groove 19.

[0037] Working principle: During use, select the corresponding number of movable limit frames 3 according to the required number of aluminum alloy profiles to be fixed. When the movable limit frame 3 is fixed with the fixed block 1, the connecting threaded rod 21 passes through the working hole 17 and the mating plate 16 and engages with the internal threaded connecting groove 19 to fix the position of the movable limit frame 3. After the position and number of the fixed limit frame 2 and the movable limit frame 3 are determined, insert the aluminum alloy profiles into the fixed limit frame 2 and the movable limit frame 3 respectively. When inserting the aluminum alloy profiles, the clamping plate 9 is in a position parallel to the aluminum alloy profiles. After the position of the aluminum alloy profiles is determined, press the locking threaded rod 14 towards the aluminum alloy profiles to push the clamping plate 9 into the fixing groove on the side wall of the aluminum alloy profiles and rotate. The locking threaded rod 14 drives the sliding plate 11 and the pressure plate 9 to rotate. The limiting rod 12 moves along the limiting slide 8 from one side of the limiting slide 8 to the other side. At this time, the pressure plate 9 rotates 90 degrees and is in a perpendicular position to the aluminum alloy profile. The end of the pressure plate 9 near the sliding plate 11 abuts against the inner side wall of the fixing groove of the aluminum alloy profile. At this time, the limiting rod 12 is located in the middle position of the limiting slide 8. Then, the locking nut 15 is rotated. The locking nut 15 cooperates with the locking threaded rod 14. After the side wall of the locking nut 15 abuts against one end of the connecting pipe 7, it continues to rotate. Then, the pressure plate 9 applies a force to the aluminum alloy profile away from the limiting frame 4, so as to fix the position of the aluminum alloy profile in cooperation with the limiting frame 4. Next, place the two auxiliary locking frames 26 outside the fixed limiting frame 2 and the movable limiting frame 3. The clamping block 28 passes through the clamping through hole 6 and abuts against the outer wall of the aluminum alloy profile. Then, tighten the locking bolt 27 to achieve auxiliary fixation of the aluminum alloy profile. Due to the setting of the fixed limiting frame 2 and the movable limiting frame 3, even if the locking bolt 27 and the locking threaded rod 14 are loose, the device still has a certain limiting effect on the aluminum alloy profile, thereby avoiding the problem of the equipment profile separating after the bolts are loose.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
