Description

Technical Field

[0001] This utility model relates to the field of aluminum brackets, and in particular to a quick-installation device for easy-to-install aluminum brackets. Background Technology

[0002] Aluminum support legs are lightweight, high-strength, corrosion-resistant, easy to process, and environmentally friendly and recyclable. They are widely used in building construction for door and window supports, ceiling supports, curtain wall supports, and more.

[0003] When using the easy-to-install aluminum outrigger quick-assembly device, first check all relevant materials and tools to ensure they are complete and undamaged, and prepare the necessary tools. At the same time, determine the installation location and clean the surface to ensure it is flat and clean. In the installation process, first assemble the main body of the bracket according to the design requirements, then install the quick-assembly connectors, then install the equipment or accessories, and finally fix the bracket to the installation location and adjust the level and verticality. After installation, check each component connection point to ensure structural stability. If possible, a load-bearing test should also be conducted to observe whether there are any abnormalities in the bracket. The entire process relies on the lightweight and easy-to-process characteristics of aluminum outriggers to make the installation operation more convenient and efficient.

[0004] The unlocking process of some similar devices on the market is significantly cumbersome, with a long and interconnected chain of steps. Unlocking requires a series of independent operations to be completed in a fixed sequence. For example, first, a screwdriver is used to unscrew the fastening screws on the side of the outer casing, then a wrench is used to adjust the tightness of the internal clips, and then the locking pins corresponding to each bracket are manually released. If any step is missing or the order is reversed, the subsequent process cannot proceed, which increases the risk of device damage and further prolongs the unlocking time, seriously affecting the overall work efficiency. To address this issue, an easy-to-install aluminum bracket quick-installation device is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 The present invention provides an embodiment of an easy-to-install aluminum bracket quick-installation device, comprising a fixed housing 1, inside which a locking mechanism 2 and a clamping mechanism 3 are provided. The locking mechanism 2 includes a bidirectional threaded rod 211, which is driven to rotate by a handwheel 217. Through the thread, the rod drives a wedge support frame 218 to move bidirectionally, providing power to the wedge 212 and enabling the unified unlocking of the aluminum legs 216. Both ends of the bidirectional threaded rod 211 are rotatably connected to the inner wall of the fixed housing 1. The outer wall of the bidirectional threaded rod 211 is threadedly connected to the wedge support frame 218 through a threaded sleeve. The wedge support frame 218 moves with the bidirectional threaded rod 211, causing the wedge 212 to slide, converting the rotational power of the bidirectional threaded rod 211 into the thrust of the wedge 212. The wedge 212 is fixedly connected to the side wall of the wedge support frame 218, and the wedge 212 moves along the inner wall of the fixed housing 1. The double-layer wedge 213 is pushed off the aluminum leg 216 by sliding and abutting, thus unlocking the locked state. The outer wall of the wedge 212 abuts against the double-layer wedge 213. After being squeezed, the double-layer wedge 213 is inserted into the inner wall of the aluminum leg 216 to achieve locking. When pushed by the wedge 212 or pulled by the first pull rod 215, it is disengaged from the aluminum leg 216 and unlocked. The side wall of the double-layer wedge 213 is elastically connected to the inner wall of the fixed shell 1 through the first spring 214. The first spring 214 connects the double-layer wedge 213 and the fixed shell 1, providing a reset elastic force. After unlocking, it assists the double-layer wedge 213 to reset, making it easy to lock next time. The first pull rod 215 is slidably connected to the inner wall of the fixed shell 1. The first pull rod 215 drives the double-layer wedge 213 to slide off the aluminum leg 216, realizing the individual unlocking of a single aluminum leg 216. The operation is convenient. The side wall of the first pull rod 215 is fixedly connected to the side wall of the double-layer wedge 213.

[0020] Reference Figures 2-4The locking mechanism 2 also includes an aluminum support leg 216, which can be directly inserted into the fixed housing 1 and fixed by interlocking with the double-layer wedge 213. As a support component to adapt to installation requirements, the outer wall of the aluminum support leg 216 is inserted into the inner wall of the fixed housing 1, the outer wall of the double-layer wedge 213 is inserted into the inner wall of the aluminum support leg 216, the outer wall of the wedge 212 is slidably connected to the inner wall of the fixed housing 1, and the outer wall of the double-layer wedge 213 is slidably connected to the inner wall of the fixed housing 1. The locking mechanism 2 also includes a handwheel 217, which is turned by the operator to drive the bidirectional threaded rod 211 to rotate, providing a manual operation interface for the unified unlocking of the aluminum support leg 216. The side wall of the handwheel 217 is fixedly connected to one end of the bidirectional threaded rod 211 that is close to each other. One end of the spring 214 is fixedly connected to the side wall of the double-layer wedge 213, and the other end of the spring 214 is fixedly connected to the inner wall of the fixed housing 1. The outer wall of the pull rod 215 is located on the inner wall of the spring 214.

[0021] Reference Figures 3-5The clamping mechanism 3 includes a rotating rod 311. The rotating rod 311 rotates under operation, causing helical gear 313 and ratchet 312 to rotate synchronously, providing power input to the clamping mechanism 3. The outer wall of the rotating rod 311 is rotatably connected to the inner wall of the fixed housing 1. Helical gear 313 is fixedly connected to the outer wall of the rotating rod 311. Helical gear 313 rotates with the rotating rod 311, meshing with helical gear 314 to achieve power transmission and direction conversion. Helical gear 314 is meshed with the outer wall of helical gear 313. Helical gear 314 meshes with helical gear 313, driving the compression ring 316 to rotate, transmitting power to the compression ring 316. The inner wall of helical gear 314 is fixedly connected to the compression ring 316. The compression ring 316 rotates with the helical gear 313. Gear 2 314 rotates and engages with connecting post 321 through arc-shaped hole 322, driving sliding block 317 to slide, converting rotational motion into linear motion. A fixed cylinder 315 is fixedly connected to the inner wall of the fixed housing 1. The fixed cylinder 315 provides installation and movement space for the extrusion ring 316 and sliding block 317, restricting the sliding direction of sliding block 317 to ensure precise clamping. The outer wall of the extrusion ring 316 is rotatably connected to the inner wall of the fixed cylinder 315. Sliding block 317 is slidably connected to the inner wall of the fixed cylinder 315. Sliding block 317 slides along the inner wall of the fixed cylinder 315, abutting against external components to achieve clamping, directly completing the fixation of the device. An arc-shaped hole 322 is provided on the outer wall of the extrusion ring 316. The clamping mechanism 3, in cooperation with the connecting post 321, converts the rotational motion of the compression ring 316 into the linear sliding motion of the sliding block 317. The connecting post 321 is slidably connected to the inner wall of the arc-shaped hole 322. The connecting post 321 connects the compression ring 316 and the sliding block 317, transmitting the power of the compression ring 316 and driving the sliding block 317 to move synchronously. The bottom end of the connecting post 321 is fixedly connected to the top end of the sliding block 317. The clamping mechanism 3 also includes a ratchet 312, which rotates with the rotating rod 311 and engages with the pawl 320 to prevent the rotating rod 311 from rotating in the opposite direction and to lock the clamping state. The inner wall of the ratchet 312 is fixedly connected to the outer wall of the rotating rod 311. The clamping mechanism 3 also includes a pull rod 318, which is pulled by the operator. The ratchet 320 disengages from the ratchet 312, releasing the clamping lock and facilitating adjustment of the clamping degree. The second pull rod 318 is slidably connected to the inner wall of the fixed housing 1. The outer wall of the second pull rod 318 is elastically connected to the ratchet 320 via the second spring 319. Under the action of the second spring 319, the ratchet 320 engages with the ratchet 312, preventing the rotating rod 311 from rotating in the opposite direction and ensuring a stable clamping state. The outer wall of the ratchet 320 is engaged with the outer wall of the ratchet 312. One end of the second spring 319 is fixedly connected to the outer wall of the second pull rod 318. The second spring 319 connects the second pull rod 318 and the ratchet 320, providing elasticity to keep the ratchet 320 engaged with the ratchet 312, ensuring reliable locking. The other end of the second spring 319 is fixedly connected to the outer wall of the ratchet 320.

[0022] Working principle: The aluminum support leg 216 can be directly inserted into the inner wall of the fixed housing 1. The double-layer wedge 213 is squeezed and then inserted into the inner wall of the aluminum support leg 216 to lock the aluminum support leg 216. When unlocking is required, turn the handwheel 217 to drive the bidirectional threaded rod 211 fixed to it to rotate on the inner wall of the fixed housing 1. The bidirectional threaded rod 211 drives the wedge support frame 218 to move through the threaded sleeve. The wedge support frame 218 drives the wedge 212 to slide along the inner wall of the fixed housing 1. The wedge 212 abuts against and pushes the double-layer wedge 213 to slide, so that the double-layer wedge 213 is separated from the inner wall of the aluminum support leg 216, realizing the unified unlocking of the four aluminum support legs 216. Pull the pull rod 215 to drive the double-layer wedge 213 to separate from the inner wall of the aluminum support leg 216. At this time, the spring 214 is squeezed, which makes it easy to remove the aluminum support leg 216 individually. Rotating the rotating rod 311 causes the helical gear 313 on its outer wall to rotate. The helical gear 313 meshes with the helical gear 314, causing the compression ring 316, which is fixed to the helical gear 314, to rotate inside the fixed cylinder 315. The arc-shaped hole 322 of the compression ring 316 drives the sliding block 317 to slide along the inner wall of the fixed cylinder 315 through the connecting column 321. The sliding block 317 abuts against the external component to achieve clamping. When the rotating rod 311 rotates, the ratchet 312 on its outer wall rotates synchronously. The pawl 320 on the outer wall of the pull rod 318 meshes with the ratchet 312 under the elastic force of the spring 319 and the pawl 320, locking the position of the rotating rod 311. Pulling the pull rod 318 can cause the pawl 320 to disengage from the ratchet 312, releasing the lock to adjust the clamping degree.

[0023] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
