[0024] The following describes the specific embodiments of the present invention to facilitate those skilled in the art of this technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are within the scope of protection.

[0025] As Figure 1 、 Figure 3 and Figure 4 shown, the present invention provides a telescopic protective fence, which includes a plurality of protective fence units. Each protective fence unit includes two vertically arranged mounting columns 1, and the two mounting columns 1 are horizontally spaced apart; a telescopic folding bracket 2 and a protective baffle 3 are horizontally arranged between the two mounting columns 1.

[0026] The protective baffle 3 includes a first baffle 301 and a second baffle 302. A sliding groove 4 is provided inside the first baffle 301. The sliding groove 4 penetrates through both end faces of the first baffle 301. A limiting plate 5 is provided at the opening on one side of the sliding groove. A notch 6 for the second baffle 302 to slide out is provided on the limiting plate 5. One side of the second baffle 302 is located inside the sliding groove 4 and a limiting block 7 cooperating with the limiting plate 5 is provided thereon. The other side of the second baffle 302 passes through the notch 6 and is located outside the sliding groove 4. The width of the limiting block 7 is greater than the width of the notch 6 and less than the width of the sliding groove 4. The purpose of such a setting is to prevent the second baffle 302 from moving to an excessive position and sliding out of the sliding groove 4, playing a role in restricting the maximum sliding displacement of the second baffle 302.

[0027] The side of the first baffle 301 away from the second baffle 302 and the other side of the second baffle 302 are respectively connected to the inner end faces of two mounting columns 1; both ends of the telescopic folding bracket 2 are respectively connected to the inner end faces of two mounting columns 1.

[0028] By providing the telescopic folding bracket 2 and the protective baffle 3 between the two mounting columns 1, the protective enclosure unit realizes the telescopic function. When transporting and stacking at the construction site, it can be conveniently stored, reduce the occupied space, facilitate transportation and installation, improve construction efficiency and safety, reduce resource waste and cost, and solve the problem that the protective fence in the prior art is not convenient for transportation due to its large volume.

[0029] As Figure 4 and Figure 5 shown, as a specific installation method between the telescopic folding bracket 2 and the protective baffle 3 and the two mounting columns 1, first mounting grooves 8 and second mounting grooves 9 are vertically and spacedly provided on the inner end faces of the two mounting columns 1; the side of the first baffle 301 away from the second baffle 302 and the other side of the second baffle 302 are respectively connected to two first mounting grooves 8; specifically, preferably, a plurality of locking screws 12 are provided on the front surface of the first baffle 301, and each locking screw 12 passes through the front surface of the first baffle 301 and abuts against the second baffle 302 in a tight manner. After the first baffle 301 and the second baffle 302 are unfolded, the relative position between the first baffle 301 and the second baffle 302 can be fixed by tightening the locking screws 12, avoiding the phenomenon that the ends of the first baffle 301 and the second baffle 302 slide out of the first mounting groove 8.

[0030] Both ends of the telescopic folding bracket 2 are respectively connected to two second mounting grooves 9. The telescopic folding bracket 2 is located behind the protective baffle 3, and the protective baffle 3 can play a role in protecting the telescopic folding bracket 2.

[0031] Specifically, the telescopic folding bracket 2 is a scissor mechanism. On both side walls of each second installation groove 9, a chute 10 is vertically arranged. The bottom of the end of the telescopic folding bracket 2 is fixed to the second installation groove 9. On both sides of the top of the end of the telescopic folding bracket 2, a connecting shaft 11 that cooperates with the chute 10 is arranged. The top of both sides of the end of the telescopic folding bracket 2 is slidably matched with the chute 10 through the connecting shaft 11.

[0032] Preferably but not limitedly, reflective stickers are provided on the front surfaces of the first baffle 301 and the second baffle 302; warning lights are provided at the tops of the two mounting columns 1. Both the reflective stickers and the warning lights are used to play a warning role.

[0033] As Figure 1 and Figure 6 As shown, specifically, at the bottom of each mounting column 1, a moving device 13 and a fixing device 14 are provided; the moving device 13 includes a threaded connecting shaft 15. The top of the threaded connecting shaft 15 is threadedly connected to the bottom of the mounting column 1. A locking nut 16 is threadedly connected to the middle of the threaded connecting shaft 15. The bottom of the threaded connecting shaft 15 is fixedly connected to a universal wheel 17.

[0034] The fixing device 14 includes a fixing rod 22. The top of the fixing rod 22 is fixedly connected to the bottom of the mounting column 1. The bottom of the fixing rod 22 is connected to a fixing plate 18 with a plurality of mounting holes 19. A mounting screw 20 is threadedly connected in each mounting hole 19. A wrench 21 is hinged to the top of each mounting screw 20.

[0035] The setting of the moving device 13 can facilitate the movement of the mounting column 1. When the mounting column 1 moves to the preset position, the universal wheel 17 can be lifted by screwing the threaded connecting shaft 15 until the fixing plate 18 contacts the ground and then stops. Then, the whole mounting column 1 can be fixed by screwing the wrench 21.

[0036] A construction method for a telescopic protective fence is as follows: When it is necessary to set up the protective fence, first, transport a plurality of protective fence units to the construction site according to the on-site requirements. Then, according to the required size on the site, carry the two mounting columns 1, the telescopic folding bracket 2, and the protective baffle 3 in the protective fence unit to the fixed place. Due to the setting of the moving device 13, it is time-saving and labor-saving to carry the protective fence unit. Then, fix one mounting column 1 at the installation position to be installed through the fixing device 14. Then, move the other mounting column 1 to another installation position for installation and fixation. When moving the other mounting column 1, the telescopic folding bracket 2 and the protective baffle 3 can be automatically unfolded, and the locking screw 12 can be tightened to fix the relative positions between the first baffle 301 and the second baffle 302, completing the construction work of a single protective fence unit. Then, according to the above scheme, construct and build a plurality of protective fence units one by one, so that the plurality of protective fence units are connected end to end to form a complete protective fence.

[0037] When demolition is required, loosen the mounting screw 20 with a wrench 21, and then rotate the threaded connection shaft 15 so that the universal wheel 17 moves downward until the universal wheel 17 contacts the bottom surface and lifts the fixing plate 18 off the bottom surface. Then loosen the locking screw 12 and push the two mounting columns 1 together to achieve the demolition and storage work of the telescopic protective fence.
