Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profiles, and specifically to a quickly splicable aluminum profile. Background Art

[0002] An aluminum profile is a profile product made of aluminum alloy as the base material through multiple processes such as extrusion, cutting, and machining. Aluminum profiles are usually formed by the extrusion method, and the aluminum alloy is extruded through a mold into profiles with different cross-sectional shapes.

[0003] The patent with the patent publication number CN216951146U relates to a quickly splicable aluminum profile, which includes two aluminum profile bodies. A splicing sleeve is sleeved on the surfaces of the two aluminum profile bodies. Four fixing blocks are fixedly connected in a ring inside the splicing sleeve. Four notches that are engaged with the fixing blocks are annularly formed on the surfaces of the aluminum profile bodies. Two symmetrically arranged sliding grooves are formed inside the fixing blocks. An inclined slider is slidably connected to the inner cavity of the sliding groove. One side of the inclined slider penetrates into the inner cavity of the splicing sleeve. A clamping groove that is engaged with the inclined slider is formed in the inner cavity of the notch. Through the cooperation of the fixing block and the notch, a limiting effect is achieved on the aluminum profile body and the splicing sleeve. Through the cooperation of the inclined slider and the clamping groove, the two aluminum profile bodies are closely attached, preventing the two aluminum profile bodies from moving away from each other, and the purpose of facilitating quick splicing can be achieved.

[0004] In the above patent, through the cooperation of the inclined slider and the clamping groove, the two aluminum profile bodies are closely attached, preventing the two aluminum profile bodies from moving away from each other, and the purpose of facilitating quick splicing can be achieved. However, after the two aluminum profiles are connected, due to the cooperation of the inclined slider and the clamping groove, the two aluminum profiles can be separated with simple operations, thereby reducing the safety of the connection between the two aluminum profiles.

[0005] Therefore, it is very necessary to design a quickly splicable aluminum profile that can prevent Aluminum Profile One and Aluminum Profile Two from being randomly disassembled, resulting in the separation of Aluminum Profile One and Aluminum Profile Two and affecting the use. Summary of the Invention

[0006] The purpose of the present invention is to provide a quickly splicable aluminum profile to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: A quick-assembling aluminum profile, including aluminum profile one and aluminum profile two, further including a splicing device and a positioning device. Among them, the splicing device includes a plug rod, a circular frame, a trapezoidal block, an arc-shaped block, a concave-shaped frame, a control shaft, and an arc-shaped plate. The plug rod is fixedly installed inside aluminum profile one, the circular frame is fixedly installed inside aluminum profile two, the trapezoidal block slides through the top of the circular frame, the arc-shaped block is fixedly installed on the surface of the trapezoidal block, the concave-shaped frame is slidably installed on the top of the circular frame, the control shaft is sleeved on the top of aluminum profile two, and the arc-shaped plate is fixedly installed on the surface of the control shaft; Among them, the positioning device includes a support frame and a limiting component. When the arc-shaped plate rotates, it will push the concave-shaped frame to move. When the concave-shaped frame contacts the inclined surface of the arc-shaped block, the concave-shaped frame will push the arc-shaped block and the trapezoidal block upward through the arc surface of the arc-shaped block, so as to release the limit of the trapezoidal block on the plug rod and aluminum profile one, and avoid the random disassembly of aluminum profile one and aluminum profile two resulting in the separation of aluminum profile one and aluminum profile two and affecting the use.

[0008] According to the above technical solution, a volute spring is provided between the control shaft and aluminum profile two, and a spring is provided between the trapezoidal block and the circular frame. The volute spring can drive the control shaft to reset.

[0009] According to the above technical solution, the support frame is fixedly installed on the surface of aluminum profile one. The limiting device includes a roller, a fixed block, a collision block, a limiting frame, and a rotating wheel. The roller is rotatably installed on the surface of the support frame, the fixed block is fixedly installed on the surface of the roller, the collision block is fixedly installed on the surface of the support frame, the limiting frame is hinged on the surface of aluminum profile one, and the rotating wheel is rotatably installed on the surface of the limiting frame, to avoid further bending at the connection position of aluminum profile one and aluminum profile two and causing danger.

[0010] According to the above technical solution, a torsion spring is provided between the limiting frame and aluminum profile one, and a groove is opened at the bottom of the limiting frame. The torsion spring can drive the limiting frame to reset. At the same time, when aluminum profile one moves, it will drive the limiting frame and the rotating wheel to move, so as to limit the up and down positions of aluminum profile one and aluminum profile two. At the same time, when the roller rotates, it will drive the fixed block to rotate. When the fixed block rotates and collides with the collision block, the collision between the fixed block and the collision block will drive aluminum profile one and aluminum profile two to vibrate, to avoid the relative position of aluminum profile one and aluminum profile two shifting and affecting the quick-assembling efficiency.

[0011] According to the above technical solution, it further includes an anti-separation device and a protection device. The protection device includes a limiting plate and a support assembly. An anti-separation device is arranged on the surface of the limiting frame. The anti-separation device includes a swing plate. The swing plate is rotatably installed on the surface of the limiting frame. A sliding plate is slidably installed on the surface of the limiting frame. A knocking rod is fixedly installed on the surface of the sliding plate. A moving plate is slidably installed on the inner wall of the groove. A bell is fixedly installed on the top of the moving plate. A clamping plate is slidably installed on the surface of the rotating wheel. When forcibly separating the first aluminum profile and the second aluminum profile, when the rotating wheel rotates in the reverse direction, it will push the swing plate to rotate. When the swing plate rotates, it will push the sliding plate to move. When the sliding plate moves, it will drive the knocking rod to move. When the knocking rod moves, it will knock the bell to generate an alarm sound, thereby prompting the surrounding staff and users.

[0012] According to the above technical solution, a return spring is arranged between the sliding plate and the limiting frame, a first spring is arranged between the moving plate and the groove, and a tension spring is arranged between the clamping plate and the rotating wheel. The return spring can support the sliding plate, so that the sliding plate can limit the rotation of the swing plate.

[0013] According to the above technical solution, the limiting plate is slidably installed on the surface of the first aluminum profile. A second spring is arranged between the limiting plate and the first aluminum profile. The support assembly includes a limiting plate, a triangular block and an arc rod. The limiting plate is slidably installed on the surface of the first aluminum profile. A card slot is formed on the surface of the limiting plate. The triangular block is fixedly installed on the surface of the limiting plate. The arc rod is fixedly installed on the surface of the limiting frame. The limiting plate will release the limit on the limiting plate. Under the action of the second spring, the limiting plate will move towards the direction of the second aluminum profile, so that the limiting plate will assist in supporting the splicing position of the first aluminum profile and the second aluminum profile. According to the above technical solution, a fixing plate is fixedly installed on the surface of the first aluminum profile. An alarm is fixedly installed on the side of the fixing plate close to the limiting plate. A third spring is arranged between the limiting plate and the first aluminum profile. When the limiting plate is bent, it will press the alarm, so that the alarm will be triggered to generate an alarm signal, prompting that the limiting plate is also bent and needs to be processed in time.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) For this quickly spliceable aluminum profile, by inserting the insertion rod into the interior of the circular frame and restricting the insertion rod through the trapezoidal block, the first aluminum profile and the second aluminum profile can be quickly spliced. Pull the control shaft upward and then rotate the control shaft so that the arc plate can move the concave frame to move. The concave frame can detect the connection of the first aluminum profile and the second aluminum profile through the arc plate, avoiding the first aluminum profile and the second aluminum profile being randomly disassembled, resulting in the separation of the first aluminum profile and the second aluminum profile and affecting the use.

[0015] (2) The quick - splicing aluminum profile can limit the positions of the first aluminum profile and the second aluminum profile through the support frame, rollers and rotating wheels, facilitating the alignment of the first aluminum profile and the second aluminum profile neatly, and avoiding the relative positions of the first aluminum profile and the second aluminum profile from shifting, which would affect the quick - splicing efficiency. When the rollers rotate, the fixed block and the collision block will collide, causing the rollers to drive the connection of the first aluminum profile and the second aluminum profile to vibrate, enabling the insertion rod to more accurately insert into the interior of the circular frame.

[0016] (3) The quick - splicing aluminum profile can limit the reverse rotation of the rotating wheel through the swing plate and the slider, further separating the first aluminum profile and the second aluminum profile. When the first aluminum profile and the second aluminum profile are forcibly separated, the swing plate will push the slider to move, and the slider will drive the knocking rod to knock the bell to produce an alarm sound. When the control shaft is pushed upward, it will drive the moving plate and the bell to move upward, so that the bell will not be knocked by the knocking rod.

[0017] (4) When the connection positions of the first aluminum profile and the second aluminum profile are bent due to extrusion, the first aluminum profile and the second aluminum profile will squeeze the limiting rod to rotate. When the limiting rod moves, it will drive the arc - shaped rod to rotate. When the arc - shaped rod rotates, it will push the triangular block and the limiting plate to move, enabling the limiting plate to release the limit on the restricting plate. The restricting plate will move towards the connection position of the first aluminum profile and the second aluminum profile, and the restricting plate can support between the first aluminum profile and the second aluminum profile, avoiding further bending of the first aluminum profile and the second aluminum profile and generating danger.

Specific embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0021] Please refer to Figures 1-6 , the present invention provides a technical solution: a quickly spliceable aluminum profile, including the first aluminum profile 1 and the second aluminum profile 2, and further including a splicing device and a positioning device. Among them, the splicing device includes an insertion rod 31, a circular frame 32, a trapezoidal block 33, an arc-shaped block 34, a concave-shaped frame 35, a control shaft 36, and an arc-shaped plate 37. The insertion rod 31 is fixedly installed inside the first aluminum profile 1, the circular frame 32 is fixedly installed inside the second aluminum profile 2, the trapezoidal block 33 slides through the top of the circular frame 32, the arc-shaped block 34 is fixedly installed on the surface of the trapezoidal block 33, the concave-shaped frame 35 is slidably installed on the top of the circular frame 32, the control shaft 36 is sleeved on the top of the second aluminum profile 2, and the arc-shaped plate 37 is fixedly installed on the surface of the control shaft 36; among them, the positioning device includes a support frame 41 and a limiting component. When the control shaft 36 rotates, it will drive the arc-shaped plate 37 to rotate. When the arc-shaped plate 37 rotates, it will contact the concave-shaped frame 35, so that when the arc-shaped plate 37 rotates, it will push the concave-shaped frame 35 to move. When the concave-shaped frame 35 contacts the inclined surface of the arc-shaped block 34, the concave-shaped frame 35 will push the arc-shaped block 34 and the trapezoidal block 33 upward through the arc surface of the arc-shaped block 34, so as to release the limit of the trapezoidal block 33 on the insertion rod 31 and the first aluminum profile 1, and avoid the first aluminum profile 1 and the second aluminum profile 2 from being randomly disassembled, resulting in the separation of the first aluminum profile 1 and the second aluminum profile 2 and affecting the use.

[0022] A scroll spring is arranged between the control shaft 36 and the second aluminum profile 2, and a spring is arranged between the trapezoidal block 33 and the circular frame 32. The scroll spring can drive the control shaft 36 to reset.

[0023] The support frame 41 is fixedly installed on the surface of the first aluminum profile 1. The limiting device includes a roller 42, a fixed block 43, a collision block 44, a limiting frame 45 and a rotating wheel 46. The roller 42 is rotatably installed on the surface of the support frame 41. The fixed block 43 is fixedly installed on the surface of the roller 42. The collision block 44 is fixedly installed on the surface of the support frame 41. The limiting frame 45 is hinged on the surface of the first aluminum profile 1. The rotating wheel 46 is rotatably installed on the surface of the limiting frame 45, preventing the connection position between the first aluminum profile 1 and the second aluminum profile 2 from being further bent and causing danger.

[0024] A torsion spring is arranged between the limiting frame 45 and the first aluminum profile 1. A groove is formed at the bottom of the limiting frame 45. The torsion spring can drive the limiting frame 45 to reset. At the same time, when the first aluminum profile 1 moves, it will drive the limiting frame 45 and the rotating wheel 46 to move, thereby restricting the up and down positions of the first aluminum profile 1 and the second aluminum profile 2. At the same time, when the roller 42 rotates, it will drive the fixed block 43 to rotate. When the fixed block 43 rotates, it will collide with the collision block 44. When the fixed block 43 collides with the collision block 44, it will drive the first aluminum profile 1 and the second aluminum profile 2 to vibrate, preventing the relative positions of the first aluminum profile 1 and the second aluminum profile 2 from shifting and affecting the quick splicing efficiency.

[0025] During the operation of the first embodiment, the first aluminum profile 1 is moved towards the second aluminum profile 2. When the first aluminum profile 1 moves, it will drive the insertion rod 31 to move. When the insertion rod 31 moves, it will insert into the inside of the circular frame 32. When the insertion rod 31 enters the inside of the circular frame 32, it will contact the inclined surface of the trapezoidal block 33. The insertion rod 31 will push the trapezoidal block 33 to move upward through the inclined surface of the trapezoidal block 33. After the insertion rod 31 completely enters the inside of the circular frame 32, the spring will drive the trapezoidal block 33 to move downward so that the trapezoidal block 33 will limit the insertion rod 31 inside the circular frame 32, thereby splicing the first aluminum profile 1 and the second aluminum profile 2 together. Pull the control shaft 36 upward. The control shaft 36 will drive the arc-shaped plate 37 to move upward. Then rotate the control shaft 36. When the control shaft 36 rotates, it will drive the arc-shaped plate 37 to rotate. When the arc-shaped plate 37 rotates, it will contact the concave-shaped frame 35, causing the arc-shaped plate 37 to push the concave-shaped frame 35 to move when it rotates. When the concave-shaped frame 35 contacts the inclined surface of the arc-shaped block 34, the concave-shaped frame 35 will push the arc-shaped block 34 and the trapezoidal block 33 to move upward through the arc surface of the arc-shaped block 34, so as to release the limit of the trapezoidal block 33 on the insertion rod 31 and the first aluminum profile 1; When the aluminum profile 1 moves in the direction of the aluminum profile 2, the aluminum profile 1 will drive the support frame 41 and the roller 42 to move. The side surface of the aluminum profile 2 will be attached to the roller 42, so as to limit the left and right positions of the aluminum profile 1 and the aluminum profile 2. At the same time, when the aluminum profile 1 moves, it will drive the limit frame 45 and the rotating wheel 46 to move, so as to limit the up and down positions of the aluminum profile 1 and the aluminum profile 2. At the same time, when the roller 42 rotates, it will drive the fixed block 43 to rotate. When the fixed block 43 rotates and collides with the collision block 44, the collision between the fixed block 43 and the collision block 44 will drive the aluminum profile 1 and the aluminum profile 2 to vibrate, so as to improve the effect of accurately inserting the insertion rod 31 into the circular frame 32. Embodiment 2:

[0026] Please refer to Figures 1-8 , on the basis of Embodiment 1, in this embodiment, it further includes an anti-separation device and a protection device. The protection device includes a limiting plate 61 and a support assembly. An anti-separation device is arranged on the surface of the limit frame 45. The anti-separation device includes a swing plate 51. The swing plate 51 is rotatably installed on the surface of the limit frame 45. A sliding plate 52 is slidably installed on the surface of the limit frame 45. A knocking rod 53 is fixedly installed on the surface of the sliding plate 52. A moving plate 54 is slidably installed on the inner wall of the groove. A bell 55 is fixedly installed on the top of the moving plate 54. A clamping plate 56 is slidably installed on the surface of the rotating wheel 46. When the aluminum profile 1 and the aluminum profile 2 are forcibly separated, when the rotating wheel 46 rotates in the reverse direction, it will push the swing plate 51 to rotate. When the swing plate 51 rotates, it will push the sliding plate 52 to move. When the sliding plate 52 moves, it will drive the knocking rod 53 to move. When the knocking rod 53 moves, it will knock the bell 55 to generate an alarm sound, so as to prompt the surrounding staff and users.

[0027] A return spring is arranged between the sliding plate 52 and the limit frame 45. A first spring is arranged between the moving plate 54 and the groove. A tension spring is arranged between the clamping plate 56 and the rotating wheel 46. The return spring can support the sliding plate 52, so that the sliding plate 52 can limit the rotation of the swing plate 51.

[0028] The limiting plate 61 is slidably mounted on the surface of the first aluminum profile 1. A second spring is provided between the limiting plate 61 and the first aluminum profile 1. The supporting assembly includes a limiting plate 62, a triangular block 63 and an arc-shaped rod 64. The limiting plate 62 is slidably mounted on the surface of the first aluminum profile 1. A card slot is formed on the surface of the limiting plate 61. The triangular block 63 is fixedly mounted on the surface of the limiting plate 62. The arc-shaped rod 64 is fixedly mounted on the surface of the limiting frame 45. The arc-shaped rod 64 will push the triangular block 63 and the limiting plate 62 to move. After the limiting plate 62 moves, it will disengage from the card slot, so that the limiting plate 62 will release the limit on the limiting plate 61. Under the action of the second spring, the limiting plate 61 will move towards the direction of the second aluminum profile 2, so that the limiting plate 61 will assist in supporting the splicing position of the first aluminum profile 1 and the second aluminum profile 2. A fixing plate 65 is fixedly mounted on the surface of the first aluminum profile 1. An alarm 66 is fixedly mounted on the side of the fixing plate 65 close to the limiting plate 61. A third spring is provided between the limiting plate 62 and the first aluminum profile 1. When the limiting plate 61 is bent, it will press the alarm 66, so that the alarm 66 will be triggered to generate an alarm signal, indicating that the limiting plate 61 is also bent and needs to be processed in time.

[0029] When the second embodiment works, the swinging plate 51 is restricted to rotate in one direction by the sliding plate 52. The clamping plate 56 and the rotating wheel 46 are restricted to rotate in the reverse direction by the swinging plate 51, so that the rotating wheel 46 restricts the separation of the first aluminum profile 1 and the second aluminum profile 2. When the first aluminum profile 1 and the second aluminum profile 2 are forcibly separated, when the rotating wheel 46 rotates in the reverse direction, it will push the swinging plate 51 to rotate. When the swinging plate 51 rotates, it will push the sliding plate 52 to move. When the sliding plate 52 moves, it will drive the knocking rod 53 to move. When the knocking rod 53 moves, it will knock the bell 55 to generate an alarm sound. When the control shaft 36 is normally pulled upward, the control shaft 36 will push the moving plate 54 upward. When the moving plate 54 moves upward, it will push the bell 55 upward. After the bell 55 moves upward, the knocking rod 53 will not be able to knock the bell 55 to generate an alarm sound. When the top of the splicing position of the first aluminum profile 1 and the second aluminum profile 2 is squeezed, the splicing position of the first aluminum profile 1 and the second aluminum profile 2 will be bent, resulting in the second aluminum profile 2 pushing the limiting frame 45 to rotate upward. When the limiting frame 45 rotates upward, it will drive the arc-shaped rod 64 to rotate. When the arc-shaped rod 64 rotates, it will contact the inclined surface of the triangular block 63, so that the arc-shaped rod 64 will push the triangular block 63 and the limiting plate 62 to move. After the limiting plate 62 moves, it will disengage from the card slot, so that the limiting plate 62 will release the limit on the limiting plate 61. Under the action of the second spring, the limiting plate 61 will move towards the direction of the second aluminum profile 2, so that the limiting plate 61 will assist in supporting the splicing position of the first aluminum profile 1 and the second aluminum profile 2. At the same time, when the limiting plate 61 is bent, it will press the alarm 66, so that the alarm 66 will be triggered to generate an alarm signal.
