[0023] In order to more clearly illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0024] According to Figures 1-8 As shown, an aluminum bracket that is easy to install includes a column assembly. The column assembly includes a first upright post 1 and a second upright post 7. The first upright post 1 and the second upright post 7 are staggered at the four end points of the bracket. Between the first upright posts 1 and the second upright posts 7 on the left and right sides, several groups of cross bars 2 are connected to each other. Preferably, the number of cross bars 2 is two groups. A support rod 3 is inserted between the cross bar 2 and the upright post. A limiting plate 4 is movably installed at one end of the support rod 3 close to the upright post. Slots 21 are opened at both ends of the cross bar 2, and plug pins 22 that cooperate with the limiting plate 4 are arranged in the slots 21. The structures of the second upright post 7 and the first upright post 1 are symmetrical to each other. Between the first upright posts 1 and the second upright posts 7 on the front and back sides, they are connected to each other by a top rod 8. The top rod 8 is inserted at the tops of the first upright post 1 and the second upright post 7.

[0025] In this embodiment, the first upright post 1 is of a square tubular structure. Through holes 11 matching the pins 22 are formed in the left and right side walls of the first upright post 1. The width of the slot 21 is the same as the width of the first upright post 1. An annular groove 23 is formed at one end of the pin 22 close to the first upright post 1. The distance from the bottom end of the annular groove 23 to the bottom of the slot 21 is the same as the width of the first upright post 1. When the cross bar 2 is installed on the upright post, the pin 22 is aligned with the through hole 11 and inserted into the through hole 11, thereby installing the cross bar 2, the first upright post 1 and the second upright post 7 together. The slot 21 abuts against the front and rear side walls of the upright post, preventing relative rotation between the cross bar 2 and the upright post, and improving the connection stability between the cross bar 2 and the upright post. The bottom end of the annular groove 23 is flush with the side wall of the upright post, so as to facilitate the fixing of the cross bar 2 by the limiting plate 4.

[0026] In this embodiment, a first T-shaped groove 24 is formed in the side wall of the cross bar 2, and a second T-shaped groove 12 is formed in the side wall of the first upright post 1. The depth directions of the first T-shaped groove 24 and the second T-shaped groove 12 are parallel to the axis of the pin 22. T-shaped blocks 31 corresponding to the T-shaped grooves are provided at both ends of the support rod 3. The T-shaped blocks 31 at both ends of the support rod 3 are sequentially inserted into the first T-shaped groove 24 and the second T-shaped groove 12, and the connection part between the cross bar 2 and the upright post is strengthened by the support rod 3.

[0027] In this embodiment, a connecting shaft 32 is fixedly installed on the T-shaped block 31 at one end of the support rod 3 close to the upright post. A kidney-shaped hole 41 matching the connecting shaft 32 is formed at the lower end of the limiting plate 4. An anti-separation platform 33 is provided at the end of the connecting shaft 32 to prevent the limiting plate 4 from separating from the support rod 3 through the anti-separation platform 33. A clamping groove 42 matching the annular groove 23 is formed at the upper end of the limiting plate 4. A notch 43 is formed at one end of the clamping groove 42 close to the kidney-shaped hole 41. The limiting plate 4 is movably installed on the connecting shaft 32. When installing the bracket, the limiting plate 4 is rotated and the notch 43 is aligned with the pin 22 to make the pin 22 located in the clamping groove 42. Then, the limiting plate 4 is pulled downward to insert the annular groove 23 into the clamping groove 42, and the cross bar 2 is fixed under the cooperation of the annular groove 23 and the clamping groove 42.

[0028] In this embodiment, a fixing groove 13 is fixedly installed and welded on the side wall of the first upright post 1 where the second T-shaped groove 12 is formed. The fixing groove 13 is located below the second T-shaped groove 12. The limiting plate 4 slides downward into the fixing groove 13, and the limiting plate 4 is fixed by the fixing groove 13.

[0029] In this embodiment, the left and right crossbars 2 are interconnected by a reinforcing bar assembly. Two sets of mounting grooves 25 for fixing the reinforcing bar assembly are provided at the top of the crossbar 2. The reinforcing bar assembly includes a first reinforcing bar 5 and a second reinforcing bar 6. The first reinforcing bar 5 and the second reinforcing bar 6 are arranged crosswise. The first reinforcing bar 5 and the second reinforcing bar 6 are respectively installed in the mounting grooves 25 at the top of the crossbar 2 and fixed by bolts, so as to improve the stability of the bracket through the reinforcing bar assembly.

[0030] When the utility model is installed, first, the pins 22 at both ends of the crossbar 2 are aligned with the through holes 11 and inserted into the through holes 11, so as to connect the left and right first upright posts 1 and second upright posts 7 through the crossbar 2. Then, the support rods 3 are inserted into the joints of the first upright post 1 and the second upright post 7 and the crossbar 2 to strengthen the joints of the crossbar 2 and the upright posts. The limiting plates 4 are connected to the pins 22 to position the crossbar 2 and the support rods 3. Then, the top rods 8 are inserted into the tops of the front and rear first upright posts 1 and second upright posts 7. Finally, the first reinforcing bar 5 and the second reinforcing bar 6 are respectively installed on the left and right crossbars 2 to complete the installation of the bracket. Most of the components of the bracket are connected by clamping or plugging, reducing the number of fastening screws, thus effectively reducing the installation time of the bracket and being beneficial to the improvement of work efficiency.
