DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 In an embodiment of the present invention, a security bracket with a reinforced load-bearing structure includes a base 1. The top of the base 1 is provided with a support assembly for load-bearing support, and the support assembly includes a pillar 21, a top rod 22, a support plate 23 and a latch 24. The top of the base 1 is welded with a pillar 21, and the inside of the pillar 21 is slidably connected with the top rod 22. The top end of the top rod 22 extends to the outside of the pillar 21 and is installed with the support plate 23 by bolts. The side wall of the top rod 22 is provided with multiple groups of equidistant limiting holes 6, and the top end of the side wall of the pillar 21 is provided with a through hole 7 connected to the limiting hole 6. The inside of the through hole 7 is slidably plugged with a latch 24 that is locked with the limiting hole 6. Both ends of the latch 24 are fixed to the side wall of the pillar 21 by a chain 8.

[0021] When in use, pull out the pin 24 from the through hole 7 and the limiting hole 6, then pull the support plate 23 upward so that the top rod 22 slides on the inner wall of the pillar 21. When the support plate 23 moves up to a suitable load-bearing support position, pick up the pin 24 and slide it through the through hole 7 into the corresponding limiting hole 6, so that the top rod 22 and the pillar 21 can be fixed together, and the height position of the support plate 23 will not move downward.

[0022] The outer wall of the pillar 21 is provided with an auxiliary component for strengthening its load-bearing capacity, the auxiliary component includes a support rod 31, a base plate 32 and a connecting rod 33. A mounting tube 9 is welded to the top of the outer wall of the pillar 21, and the side wall of the mounting tube 9 is hingedly connected to the support rod 31. The end of the support rod 31 away from the mounting tube 9 is rotatably connected to the top of the base plate 32 through a bearing. A rectangular groove 10 is provided on the side wall of the support rod 31, and a connecting rod 33 is slidably connected to the inside of the rectangular groove 10, and the side wall of the connecting rod 33 is connected to the support rod 31 by a limiting structure. The other end of the connecting rod 33 is hingedly connected to the bottom of the support plate 23. Three support rods 31 are provided and are distributed circumferentially on the side wall of the mounting tube 9, which are used to increase the stability of the support plate 23 when the support rod 31 and the connecting rod 33 assist in strengthening the load-bearing capacity.

[0023] The limiting structure includes a spring 41, a baffle 42 and a U-shaped rod 43. The connecting rod 33 is located on both sides of the rectangular groove 10 and has movable grooves 11. The inner wall of the movable groove 11 is welded with a spring 41. The other end of the spring 41 is welded to the side wall of the baffle 42. The end of the baffle 42 away from the spring 41 is fixedly installed with a U-shaped rod 43. Waist-shaped grooves 12 and several evenly distributed fixing holes 13 are symmetrically provided on both sides of the support rod 31. The waist-shaped groove 12 is connected to the rectangular groove 10 and is located above the fixing hole 13. One end of the U-shaped rod 43 passes through the waist-shaped groove 12 and is slidably inserted into the inside of the fixing hole 13.

[0024] When the support plate 23 stops adjusting the height, the force applied to the U-shaped rod 43 is released, and the spring 41 is reset, thereby allowing one end of the U-shaped rod 43 to slide into the corresponding fixing hole 13 through the baffle 42, thereby fixing one end of the connecting rod 33 to the support rod 31 together, and then strengthening the load-bearing support of the support plate 23 through the cooperation of the connecting rod 33 and the support rod 31, so that it can perform stable load-bearing support operation.

[0025] The side of the support rod 31 away from the connecting rod 33 is provided with a fixing assembly for supporting and fixing it. The fixing assembly includes a fixing rod 51, a sleeve 52 and a fixing ring 53. The middle part of the side of the support rod 31 away from the connecting rod 33 is hingedly connected to the fixing rod 51. The outer wall of the pillar 21 is slidingly sleeved with a sleeve 52. The other end of the fixing rod 51 is hingedly connected to the side wall of the sleeve 52. The bottom surface of the sleeve 52 is movably connected to the fixing ring 53 located on the outer wall of the pillar 21. The fixing ring 53 is rotatably connected to the pillar 21 through a thread. When in use, When the bottom end of the support rod 31 changes position as the connecting rod 33 moves upward, one end of the fixed rod 51 hingedly connected to the middle part of one side of the support rod 31 moves accordingly. At the same time, the other end of the fixed rod 51 drives the sleeve 52 to slide on the outer wall of the pillar 21. After the sleeve 52 stops moving, the fixing ring 53 is rotated to make it contact with the bottom surface of the sleeve 52, thereby fixing and restricting the position of the sleeve 52 so that it will not be displaced, thereby improving the stability of the support rod 31 when providing auxiliary support.

[0026] Working principle: When using the security bracket with a reinforced load-bearing structure, first pull out the pin 24 from the through hole 7 and the limit hole 6, then pull the U-shaped rod 43 to make one end of it disengage from the fixing hole 13. When the U-shaped rod 43 is pulled, the spring 41 is stretched through the baffle 42, and then the support plate 23 is pulled upward so that the top rod 22 moves upward synchronously on the inner wall of the pillar 21. When the support plate 23 is pulled, one end of the connecting rod 33 hingedly connected to it moves synchronously. At this time, the other end of the connecting rod 33 slides in the rectangular groove 10, thereby driving the bottom end of the support rod 31 to move, and the top end of the support rod 31 is in the rectangular groove 10. The side wall of the mounting tube 9 rotates, and at the same time, the fixing rod 51 hingedly connected to the middle part of one side of the support rod 31 drives the sleeve 52 to slide on the outer wall of the pillar 21. When the support plate 23 moves up to a suitable load-bearing support height, the pin 24 is slid through the through hole 7 and inserted into the corresponding limit hole 6, and then the force applied to the U-shaped rod 43 is released. At this time, the spring 41 elastically resets, so that the U-shaped rod 43 slides into the corresponding fixing hole 13, and then the fixing ring 53 is rotated to make it contact with the bottom surface of the sleeve 52, which can fix and limit the sleeve 52, thereby improving the load-bearing stability of the security bracket with a reinforced load-bearing structure.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
