[0002] Guardrails mainly have the functions of isolation and safety warning. For isolation, guardrails have the characteristics of isolating different sections and can be used in environments such as roads and lawns to play the role of isolation and to prevent pedestrians from crossing the line. For safety warning, guardrails also have a striking appearance and can block the flow of people. They can be used in scenes such as parks, scenic spots, and high-rise corridors. They can play the role of safety warning and prevent people from walking into dangerous areas. The role of guardrails here is to remind people to pay attention.
[0003] Most existing guardrails are made in fixed sizes when in use. Therefore, they can only provide protection within a specified range when in use, resulting in the guardrail being unable to be adjusted in height and width according to actual protection needs. At the same time, the size of the guardrail is large and inconvenient, which brings inconvenience to the movement of the guardrail. Therefore, we propose a lightweight guardrail assembly and guardrail. Utility Model Content

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0027] Example 1
[0028] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a lightweight guardrail assembly, including two brackets 1, each of which is fixedly connected to a base 11, a non-slip pad 12 is fixedly connected to the bottom of the left bracket 1, and a plurality of grooves are opened on the bottom of the right base 11. The front and rear sides of the inner walls of the plurality of grooves are rotatably connected to movable wheels 13 through a rotating shaft. The bottom of the plurality of movable wheels 13 is in the same plane as the bottom of the non-slip pad 12. The opposite side of the two brackets 1 includes:
[0029] The adjustable guardrail assembly 2 includes a plurality of long guardrails 21 and a short guardrail 22. The plurality of long guardrails 21 are arranged in an interlaced manner, and the plurality of short guardrails 22 are arranged on the left and right sides.
[0030] The connecting component 3 includes multiple first connecting shafts 31. Multiple circular openings are opened in front of the long guardrail 21 and the front of the short guardrail 22. The multiple first connecting shafts 31 are arranged inside the circular openings. The front and rear ends of the first connecting shafts 31 are fixedly connected to the limiting blocks. Two connecting frames 32 are arranged inside the bracket 1. A second connecting shaft 33 is arranged below the inside of the bracket 1. The second connecting shaft 33 is arranged below the connecting frame 32.
[0031] The rod walls of multiple first connecting shafts 31 are rotatably connected to the inner walls of the corresponding two long guardrails 21 and the inner walls of the short guardrails 22. The inner walls of multiple connecting frames 32 are rotatably connected to one end of the long guardrail 21 and one end of the short guardrail 22 through rotating shafts. The rod walls of the two second connecting shafts 33 are rotatably connected to the lower ends of the long guardrails 21 on the left and right sides, and the front and rear ends of the second connecting shafts 33 are rotatably connected to the front and rear sides of the inner wall of the bracket 1 respectively.
[0032] An adjustment assembly 4 is provided inside the left bracket 1. The adjustment assembly 4 includes a screw rod 41. The screw rod 41 is provided on the left side of the connecting frame 32. A moving block 42 is threadedly connected to the upper side of the rod wall of the screw rod 41. A connecting block 43 is sleeved at the center of the rod wall of the screw rod 41.
[0033] The upper and lower ends of the screw rod 41 are rotatably connected to the upper and lower sides of the inner wall of the bracket 1 respectively, and the right side of the moving block 42 and the right side of the connecting block 43 are fixedly connected to the left side of the connecting frame 32 on the left.
[0034] A driving assembly 44 is provided below the inner wall of the left side bracket 1, and the driving assembly 44 includes a worm gear 441. The right side of the worm gear 441 is meshed with a worm 442, and the front end of the worm 442 is fixedly connected to a rotating handle 443. The rotating handle 443 is provided in front of the bracket 1, and the front end of the worm 442 passes through the front side of the inner wall of the bracket 1 to the front thereof.
[0035] The inner wall of the worm wheel 441 is fixedly connected to the lower side of the rod wall of the screw rod 41, and the front and rear ends of the worm 442 are rotatably connected to the front and rear sides of the inner wall of the bracket 1 respectively.
[0036] During use, the guardrail body is moved to the position of use, and all the long guardrails 21 and short guardrails 22 are adjusted according to the length of protection required. At this time, the left bracket 1 is placed on the ground through the anti-slip pad 12 on the base 11. Under the action of the anti-slip pad 12, the friction coefficient with the ground is increased to prevent the left bracket 1 from moving;
[0037] By turning the rotating handle 443, the worm 442 is driven to rotate, and the worm 442 drives the worm wheel 441 on the screw rod 41 to rotate, so that the screw rod 41 can rotate. At this time, after the screw rod 41 rotates, it drives the moving block 42 to move. When the moving block 42 moves upward, the overall height of the long guardrail 21 and the short guardrail 22 increases and the width becomes narrower. When the moving block 42 moves downward, the overall height of the long guardrail 21 and the short guardrail 22 decreases and the width becomes wider, thereby achieving the adjustment of the height and width of the guardrail body and adjusting the guardrail to the required size;
[0038] After the screw rod 41 moves, the long guardrail 21 and the short guardrail 22 are connected through the first connecting shaft 31. Therefore, when the long guardrail 21 on the upper left changes, the angle between the long guardrail 21 and the short guardrail 22 changes. The long guardrail 21 in the lower middle part of the bracket 1 rotates inside the bracket 1 through the second connecting shaft 33, and the position of the lower end of all the long guardrails 21 remains unchanged. After the angle of the short guardrail 22 changes, the long guardrail 21 slides in the bracket 1 through the connecting block 43 on the connecting frame 32.

[0040] Reference Figure 1-4 , which is the second embodiment of the present utility model, a limiting assembly 5 is provided inside the right bracket 1, and the limiting assembly 5 includes a limiting rod 51, and the upper and lower ends of the limiting rod 51 are fixedly connected to the upper and lower sides of the inner wall of the right bracket 1 respectively, and the rod wall of the limiting rod 51 is slidably connected to two sliders 52, and the left sides of the two sliders 52 are fixedly connected to the right side of the connecting frame 32 on the right.
[0041] During use, after the moving block 42 on the left moves, the connecting frame 32 on the right slides on the limit rod 51 through the slider 52, connecting the long guardrail 21 and the short guardrail 22 to the brackets 1 on the left and right sides. Therefore, after the height of the long guardrail 21 on the left is adjusted, the height of all the long guardrails 21 and the short guardrail 22 changes, and the length changes at the same time. Therefore, the slider 52 on the right connecting frame 32 will slide on the limit rod 51, and through the change of the overall length of the long guardrail 21 and the short guardrail 22, the moving wheel 13 on the right bracket 1 is driven to move on the ground.
[0042] The remaining structures are the same as those of Example 1.
