[0035] Please see Figure 1-13 In this embodiment of the present invention, a guardrail with adjustable support includes multiple guardrail components 1, and a support 2 is provided between the multiple guardrail components 1. The two sides of the multiple support 2 are respectively fixedly connected to the ends of the multiple guardrail components 1.
[0036] The guardrail assembly 1 includes a guardrail body 11, the upper end of which is fixedly connected to a connecting shaft 12, and the length of the connecting shaft 12 is greater than the length of the guardrail body 11; the bracket 2 includes a housing assembly 21, inside which two adjusting components 24 are symmetrically arranged, and the two adjusting components 24 are respectively connected to two driving components 23.
[0037] The adjustment assembly 24 includes a connecting cylinder 241, with the end of the connecting shaft 12 located inside the connecting cylinder 241; one end of the connecting cylinder 241 away from the connecting shaft 12 is fixedly connected to the middle of the support plate 242, and both ends of the support plate 242 away from the connecting cylinder 241 are provided with threaded seats 243, and both threaded seats 243 are provided with through threaded holes; the drive assembly 23 includes a lead screw 231, and the lead screw 231 is located inside the threaded holes of the two threaded seats 243 and is threadedly connected to the two threaded holes.
[0038] The bearing plate 242 is cross-shaped, and connecting plates 244 are fixedly connected to both sides of the bearing plate 242. Auxiliary wheels 245 are rotatably connected to both ends of the side of the two connecting plates 244 away from the bearing plate 242. The two threaded seats 243 are fixedly connected to the bearing plate 242 by multiple angle irons 246.
[0039] The top of the lead screw 231 is coaxially fixedly connected to a handle wheel 232, and the handle wheel 232 is located above the housing assembly 21; both sides of the housing assembly 21 are fixedly connected to side plate assemblies 22.
[0040] By adopting the above technical solution, the operator can rotate the screw 231 by rotating the handle wheel 232. During the rotation, the screw 231 can drive the two threaded seats 243 that are meshed together to move vertically. The connecting cylinder 241 can move synchronously with the threaded seats 243, thereby allowing the guardrail assembly 1 to move vertically as a whole. By changing the height of the guardrail assembly 1, the guardrail can be installed on uneven ground, increasing the applicability of the guardrail.
[0041] In this embodiment, the outer shell assembly 21 includes an outer shell 211, and multiple guide grooves 212 are symmetrically fixedly connected to both sides of the inner side of the outer shell 211. The multiple guide grooves 212 are all arranged vertically, and the length of the multiple guide grooves 212 is less than the length of the lead screw 231. The side of the multiple auxiliary wheels 245 away from the connecting plate 244 is respectively located in the multiple guide grooves 212.

The multiple movable grooves 222 limit the range of motion of the bearing plate 242, preventing the lead screw 231 from spinning freely. In addition, the multiple auxiliary wheels 245 can make the bearing plate 242 move more smoothly, reduce the wear of the thread of the lead screw 231, and extend the service life of the lead screw 231.
[0045] The working principle of this utility model is as follows: the operator can drive the lead screw 231 to rotate by rotating the handle wheel 232. During the rotation, the lead screw 231 can drive the two threaded seats 243 that are meshed together to move vertically. The connecting cylinder 241 can move synchronously with the threaded seats 243, thereby allowing the guardrail assembly 1 to move vertically as a whole. By changing the height of the guardrail assembly 1, the guardrail can be installed on uneven ground, increasing the applicability of the guardrail.
[0046] The movable groove 222 of the side plate 221 provides sufficient range of motion for the vertical movement of the connecting cylinder 241; when the threaded seat 243 moves vertically, multiple auxiliary wheels 245 slide vertically in multiple movable grooves 222 respectively. The multiple movable grooves 222 limit the range of motion of the bearing plate 242 and prevent the lead screw 231 from spinning freely. In addition, the multiple auxiliary wheels 245 can make the bearing plate 242 move more smoothly, reduce the wear of the thread of the lead screw 231, and extend the service life of the lead screw 231.
