Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a modularly assembled guardrail for municipal engineering projects. Background Art

[0002] Municipal road guardrails are also called urban traffic galvanized spray-coated steel guardrails. They are beautiful and novel, easy to install, safe and reliable, and have favorable prices. They are suitable for isolation of urban traffic arteries, green belts in the middle of highways, bridges, secondary highways, township roads and various highway toll gates. Municipal guardrails include: municipal road isolation guardrails, pedestrian road guardrails, motorized and non-motorized isolation guardrails, road center isolation guardrails, lawn and flower bed guardrails, etc. Municipal road isolation guardrails have many specifications and varieties, and are used for safety protection of municipal projects, roads, factories, development zones, garden squares and other places.

DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1

[0024] Combine Figure 1-Figure 5 A modularly assembled guardrail for municipal engineering includes a base 100, a column 200 is fixedly connected to the top of the base 100, a splicing mechanism 300 is provided on the column 200, and a moving mechanism 400 is provided on the column 200 and the base 100.

[0025] See Figure 2 and Figure 3, it is further obtained that the splicing mechanism 300 includes square grooves 301 opened at both ends of the column 200, and the number of square grooves 301 is set four and is symmetrical about the center line of the column 200, the inner walls of the four columns 200 are rotatably connected with telescopic sleeves 302, and the inner walls of the four telescopic sleeves 302 are slidably connected with telescopic columns 303, one end of the telescopic column 303 on one side is rotatably connected with a threaded column 304, and one end of the telescopic column 303 on the other side is rotatably connected with a threaded sleeve 305, a threaded groove 306 is opened at the bottom end of the square groove 301 on one side, and an annular groove 307 is opened at the bottom end of the square groove 301 on the other side, two groups of threaded columns 304 are adapted to the threaded sleeve 305, two groups of threaded columns 304 are adapted to the threaded groove 306, and the threaded sleeve 305 is adapted to the annular groove 307.

[0026] Specifically, the telescopic column 303 can be stored in the telescopic sleeve 302, and the telescopic sleeve 303 can be stored in the square groove 301, and the threaded column 304 and the threaded sleeve 305 are rotated to rotate into the threaded groove 306 and the annular groove 307 respectively, so that the telescopic sleeve 302 and the telescopic column 303 can be limited, thereby completing the overall storage and organization, thereby reducing the overall volume, and when splicing, only the threaded column 304 needs to be rotated into the threaded sleeve 305 to complete the splicing operation, which is convenient and quick.

[0027] Example 2

[0028] See Figure 4 and Figure 5 , and on the basis of Example 1, it is further obtained that the moving mechanism 400 includes a groove 401 opened at the bottom end of the base 100, and a square block 402 is provided on the inner wall of the groove 401. The four corners of the bottom end of the square block 402 are fixedly connected to universal wheels 403. The moving mechanism 400 also includes a stopper 404 symmetrically fixedly connected to the bottom of the inner wall of the groove 401, and the two stoppers 404 are used to block the square blocks 402. Both sides of the top of the square block 402 are fixedly connected to a moving column 405 and pass through the base 100. Four telescopic grooves 406 are opened at both ends of the two moving columns 405, and the inner walls of the eight telescopic grooves 406 are provided with square stop columns 407. Springs 408 are fixedly connected between the eight groups of square stop columns 407 and the telescopic grooves 406. Square rings 409 are provided on the outer walls of the two moving columns 405, and the two square rings 409 are fixedly connected to the column 200 through the fixed block.

[0029] Specifically, the square block 402 moves up and down in the groove 401. When the universal wheel 403 contacts the ground, the whole can be moved, so that the position can be changed conveniently. When the universal wheel 403 does not contact the ground, the guardrail can be placed stably. The block 404 can prevent the square block 402 from leaving the groove 401 when it moves downward. The position of the square block 402 can be changed by moving the column 405, and the square ring 409 can block the square block column 407, so that the movement or placement can be limited.

[0030] The upper end of the square stop post 407 is clamped on the bottom end of the square ring 409 to complete the position restriction of the movable column 405, thereby completing the position restriction of the square block 402 and facilitating the movement of the guardrail through the universal wheel 403, thereby facilitating the change of the position. After the position is changed, the universal wheel 403 is stored in the groove 401 through the above structure, thereby increasing the placement stability and improving the stability effect.

[0031] After placement, the threaded column 304 and the threaded sleeve 305 can be rotated to leave the range of the threaded groove 306 and the annular groove 307 respectively, and the limit on the telescopic column 303 can be released. Then, the telescopic sleeve 302 and the telescopic column 303 can be adjusted to a horizontal state, and the telescopic column 303 can be stretched. Then, the threaded column 304 can be rotated into the threaded sleeve 305 to complete the splicing operation of the guardrail. It is simple and convenient, and when it needs to be moved, the telescopic sleeve 302 and the telescopic column 303 can be stored in the square groove 301, reducing the overall volume, facilitating subsequent moving operations, and increasing convenience.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
