The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-6, the present invention provides a technical solution:

a novel multifunctional guard rail special for road and bridge green belts comprises a placing plate 1, a bottom plate 2 is fixedly arranged on the upper side of the placing plate 1, a plurality of first hinged supports 201 are linearly and equidistantly arranged on the upper side of the bottom plate 2, supporting rods 202 are rotatably connected to the upper sides of the first hinged supports 201 through pin shafts, a limiting block 203 is arranged at the upper end of the right side of the supporting rod 202 at the right end, a clamping groove 204 is formed in the middle of the upper side of the limiting block 203, two limiting pins 205 are symmetrically and fixedly arranged at the right end of the bottom plate 2, an annular groove 206 is formed in the middle of the circumferential outer wall of each limiting pin 205, a top plate 3 is arranged above the bottom plate 2, a plurality of second hinged supports 301 are linearly and equidistantly arranged on the bottom surface of the top plate 3, a limiting frame 302 is arranged at the right end of each second hinged support 301 on the right side, two guide grooves 303 are symmetrically formed in the middle of the inner side of the limiting frame 302, an L-shaped handle 304 is formed in the middle of the upper side of the L-shaped handle 304, a circular groove 306 is internally connected and fixed with a spring A307, cavity 308 has been seted up to L type 304 left side inside of shaking hands, L type 304 left side below of shaking hands is equipped with limiting cam 309, limiting cam 309 upper end is passed L type and is shaken hands 304 outer wall and extend to cavity 308 inside and weld limiting plate 3010, limiting plate 3010 upside is equipped with spring B3011, two limiting cavity 207 have been seted up to the inside symmetry in bottom plate 2 left side, 2 left sides of bottom plate are connected with push rod 4 through the round pin hub rotation, 4 rear ends of push rod pass bottom plate 2 outer wall and extend to limiting cavity 207 inside and weld the fore-set 401, the inside sliding connection of limiting cavity 207 has limiting sleeve 402, two through-holes 403 have been seted up to limiting sleeve 402 left side circumference outer wall symmetry, the inside sliding connection of limiting sleeve 402 has clamp plate 404, clamp plate 404 left side symmetry is equipped with even limiting ball 405, clamp plate 404 right side is equipped with spring C406. Cooperation between the structure for the device is through the design of L type 304 and the spacing cam 309 of shaking hands, make guard rail all around all can be put down, construction and maintenance extremely convenient to the greenbelt, need not the detour can directly go on, the efficiency of construction is improved, staff's work load has been reduced, simultaneously when not being under construction or unmanned, can lift it the back automatic fixation, it is very convenient, avoided reserving the mouth and leaded to the condition that pedestrian etc. can pass in and out easily or will destroy the greenbelt.

Specifically, the upper end of the support rod 202 is rotatably connected with the lower side of the second hinge base 301 through a pin shaft, the support rod 202 and the limiting frame 302 on the right side are arranged in an integrally formed structure, and the upper end of the spring a307 is fixedly connected with the bottom surface of the top plate 3. Through the arrangement of the spring a307, after the support rod 202 is rotatably supported, the L-shaped handle 304 can be pushed down and fixed.

Further, the right end of the limiting block 203 is arranged in an inclined plane structure, the inclined plane of the limiting block 203 is connected with the lower end of the limiting cam 309 in a sliding mode, and the clamping groove 204 is matched with the limiting cam 309 in a clamping mode. Through the design of the inclined plane of the limiting block 203, when the top plate 3 is lifted, the limiting cam 309 can directly enter the clamping groove 204 through the guide of the inclined plane of the limiting block 203, and through the design of the spring B3011, the limiting cam 309 can be shortened, and the limiting cam 309 can be conveniently inserted into the clamping groove 204 to be fixed and limited.

Still further, two slide rails 305 are symmetrically arranged on the outer wall of the left side of the L-shaped handle 304, and the guide groove 303 is slidably connected with the slide rails 305. The L-shaped handle 304 can only move up and down along a straight line due to the design of the slide rail 305.

Furthermore, the diameter of the limiting ball 405 is larger than that of the through hole 403, and the outer circumferential wall of the limiting ball 405 penetrates through the inside of the through hole 403 to extend to the outside and is in clamping fit with the annular groove 206. The push rod 4 enables the jack posts 401 to push the limiting sleeves 402 to move rightwards, at the moment, the springs C406 still push the pressing plates 404, so that the limiting balls 405 are outward, the limiting balls 405 are separated from the annular grooves 206, the limiting balls are directly detached, and manpower and material resources are saved.

It is worth to be noted that the limiting cavity 207 and the limiting sleeve 402 are both arranged in a structure with a small outside and a large inside, so that the limiting sleeve 402 can move in the limiting cavity 207, but the moving distance is limited due to different diameters; the top column 401 is abutted against the outer side of the left end of the limiting sleeve 402. The top column 401 is abutted against the outer side of the left end of the limiting sleeve 402, so that the limiting sleeve 402 can be pushed to move.

The working principle is as follows: when the novel special multifunctional guard rail for the road and bridge green belt is needed, firstly, the folded guard rail is transported to a required position, at the moment, one side with a limiting pin 205 is inserted into the limiting cavity 207, because the diameter of the limiting ball 405 is larger than that of the through hole 403, the peripheral outer wall of the limiting ball 405 penetrates through the through hole 403 to extend to the outside and is in clamping fit with the annular groove 206, because the spring C406 pushes the pressing plate 404, the limiting ball 405 is clamped with the annular groove 206, at the moment, the top plate 3 is pulled by hand, because the upper end of the supporting rod 202 is rotatably connected with the lower side of the second hinge base 301 through the pin shaft, the supporting rod 202 and the limiting frame 302 on the right side are arranged in an integrated structure, the upper end of the spring A307 is fixedly connected with the bottom surface of the top plate 3, the supporting rod 202 is rotatably supported, and because the spring A307 and the right end of the limiting block 203 are arranged in an inclined surface structure, the inclined surface of the limiting block 203 is slidably connected with the lower end of the limiting cam 309, draw-in groove 204 and spacing cam 309 joint cooperation, design on the inclined plane through stopper 203, make it when lifting up roof 3, spring A307 promotes the L type 304 of shaking hands, thereby inside spacing cam 309 can directly enter into draw-in groove 204 through the inclined plane direction of stopper 203, and through the design of spring B3011, make spacing cam 309 can shorten, it is fixed spacing to make things convenient for spacing cam 309 to insert in draw-in groove 204, thereby form the fixed stay, when needs some as the opening, only need shake hands the L type 304 and go up to push away put can.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
