DETAILED DESCRIPTION

[0027] The utility model will be further described in connection with the drawings and specific embodiments.

[0028] As Figures 1 to 2 shown, the embodiment of the utility model discloses a construction site safety fence, which comprises:

[0029] The guardrail is provided with a rectangular plate 15 at the top of the guardrail;

[0030] The mounting mechanism comprises a top frame 8, a plurality of rotating handles 17, a plurality of threaded columns 18, a plurality of top clamping plates 23 and a plurality of bottom clamping plates 20, the bottom of the top frame 8 is fixedly connected with the top of the rectangular plate 15, the bottom of the plurality of bottom clamping plates 20 is fixedly connected with the inner wall of the bottom of the top frame 8 to form a mounting position, the spray pipe 7 is placed in the mounting position formed by the plurality of bottom clamping plates 20, the bottom of the plurality of rotating handles 17 is respectively fixedly connected with the top of the plurality of threaded columns 18, the top of the top frame 8 is provided with a plurality of threaded holes, the bottom of the plurality of threaded columns 18 is respectively screwed through the threaded holes and is respectively rotatably connected with the top of the plurality of top clamping plates 23, the top clamping plate 23 is fixedly connected with the bottom clamping plate 20 from the top to realize the fixation of the spray pipe 7.

[0031] Because the bottom of the plurality of bottom clamping plates 20 is fixedly connected with the inner wall of the bottom of the top frame 8 to form a mounting position, the bottom of the handle is fixedly connected with the top of the threaded column 18, the top of the top frame 8 is provided with a threaded hole, the bottom of the threaded column 18 is screwed through the threaded hole and is rotatably connected with the top of the top clamping plate 23, therefore, when the spray pipe 7 is mounted on the guardrail, the user can place the spray pipe 7 in the mounting position formed by the plurality of bottom clamping plates 20, then rotate the rotating handle 17 to make the top clamping plate 23 move downward, so that the top clamping plate 23 and the bottom clamping plate 20 respectively clamp and fix the spray pipe 7 from both sides; when the spray pipe 7 is disassembled from the guardrail, the user can rotate the rotating handle 17 to make the top clamping plate 23 move upward, so that the top clamping plate 23 is separated from the spray pipe 7, then the spray pipe 7 is taken off from the mounting position formed by the plurality of bottom clamping plates 20, the disassembly is completed, compared with the prior art of fixing the spray pipe 7 on the guardrail by a strap or a band, the mounting and dismounting of the present application are simpler, thereby improving the dismounting efficiency.

[0032] It should be noted that the top frame 8 can be connected to the rectangular plate 15 by welding or other fixing methods.

[0033] It can be understood that the general spray pipe 7 is generally cylindrical, therefore, in the present embodiment, the top clamping plate 23 and the bottom clamping plate 20 are provided in an arc shape, so as to increase the contact area with the spray pipe 7 and better fix the spray pipe 7. If the spray pipe 7 is of other shapes, the shape of the top clamping plate 23 and the bottom clamping plate 20 can be adaptively adjusted according to the surface shape of the spray pipe 7, so as to strengthen the clamping and fixing ability of the top clamping plate 23 and the bottom clamping plate 20 to the spray pipe 7.

[0034] As shown in FIG. 1, Figure 2 In some embodiments, the mounting mechanism further comprises a plurality of anti-skid pads 19, the anti-skid pads 19 are installed on the contact surface of the top clamping plate 23 and the spray pipe 7, and the contact surface of the bottom clamping plate 20 and the spray pipe 7.

[0035] The anti-skid pads 19 are arranged on the contact surfaces between the top clamping plates 23 and the spraying pipes 7 and between the bottom clamping plates 20 and the spraying pipes 7, so as to further enhance the clamping ability of the top clamping plates 23 and the bottom clamping plates 20 on the spraying pipes 7 and prevent the spraying pipes 7 from falling off.

[0036] As shown in Figure 2 some embodiments, the bottom clamping plates 20 are provided with connecting rods 21, and the bottoms of the bottom clamping plates 20 are fixedly connected to the inner walls of the bottom of the top frame 8 through the connecting rods 21.

[0037] As shown in Figure 3 some embodiments, the side of the top frame 8 is provided with a vertical sliding groove 14, and one side of the top clamping plate 23 is provided with a sliding plate 13, and the sliding block on the sliding plate 13 is slidably connected to the sliding groove 14.

[0038] Since the bottom of the threaded column 18 is rotatably connected to the top of the top clamping plate 23, in order to avoid that the top clamping plate 23 is affected by the friction force and rotates with the threaded column 18 during rotation, the sliding plate 13 is arranged on one side of the top clamping plate 23, and the sliding block can slide in the sliding groove 14 on the side of the top frame 8, so as to limit the rotation of the top clamping plate 23 and increase the stability of the top clamping plate 23.

[0039] As shown in Figure 2 some embodiments, in order to make the installation more convenient, the number of the rotating handles 17, the threaded columns 18, the top clamping plates 23 and the bottom clamping plates 20 is set to two, and the number of the anti-skid pads 19 is set to four. By reducing the number of the rotating handles 17, the threaded columns 18, the top clamping plates 23 and the bottom clamping plates 20, the objects that need to be operated by the user are reduced, and the installation is thus more simple. It should be noted that the number of the rotating handles 17, the threaded columns 18, the top clamping plates 23 and the bottom clamping plates 20 can be selected by the user, for example, the user can increase the number of the rotating handles 17, the threaded columns 18, the top clamping plates 23 and the bottom clamping plates 20 if the user wants to install more firmly.

[0040] As shown in Figures 2 to 4 some embodiments, the inner walls of the bottom of the top frame 8 are provided with inclined surfaces 16 on both sides, and the outer side of the spraying pipe 7 is provided with a plurality of spray heads for dust removal. Since the spray heads of the spraying pipe 7 are affected by the environment or the process during the spraying process, a part of the water mist enters the top frame 8. In order to avoid water accumulation in the top frame 8, the inner walls of the bottom of the top frame 8 are provided with inclined surfaces 16 on both sides, so that the water mist entering the top frame 8 can flow out of the inside of the top frame 8 from the inclined surfaces 16.

[0041] In some embodiments, the installation mechanism further comprises a shielding mechanism installed on the installation mechanism and used in cooperation with the top frame 8 to shield the spraying pipe 7.

[0042] Because the spray pipe 7 is exposed during construction, it is easy to be damaged by collision and other accidents, which leads to the replacement of the spray pipe 7 and affects the construction. Therefore, the shielding mechanism cooperates with the top frame 8 to shield the spray pipe 7 that does not need to spray, so as to avoid damage to the spray pipe 7, ensure the construction progress, and prolong the service life of the spray pipe 7.

The top of the top frame 8 is provided with a through slot 26, the shielding plate 12 penetrates through the through slot 26, the shielding plate 12 can slide up and down on the through slot 26 of the top frame 8, the limiting plate 24 is fixedly connected with the shielding plate 12 and is used for limiting the shielding plate 12 from separating from the through slot 26 of the top frame 8, the clamping ring 22 is hinged to the top of the top frame 8, and the clamping block 25 is fixedly connected with the limiting plate 24.

[0044] When the spray pipe 7 needs to spray, the shielding plate 12 slides up, the clamping ring 22 is clamped with the clamping block 25, and the position of the shielding plate 12 is fixed.

[0045] When the spray pipe 7 does not need to spray, the shielding plate 12 slides down, the bottom of the shielding plate 12 abuts against the inner wall of the bottom of the top frame 8, and the top frame 8 shields the spray pipe 7.

[0046] The user can expose or shield the spray pipe 7 by controlling the shielding plate 12 to slide up and down, which does not affect the work of the spray pipe 7 and can protect the spray pipe 7.

[0047] As shown in Figure 1 , Figure 3 , Figure 4 some embodiments, the shielding mechanism further includes a top plate 9, a connecting strip 11, and a connecting plate 10. The bottom side of the top plate 9 is fixedly connected with the top of the shielding plate 12, the other bottom side of the top plate 9 is fixedly connected with the top of the connecting strip 11, and the side surface of the top plate 9 is fixedly connected with the connecting plate 10.

[0048] The top plate 9 and the connecting strip 11 together can shield the threaded column 18 and the rotating handle 17, so that the overall structure is more tidy, and the user can use the connecting plate 10 to pull the shielding plate 12.

[0049] As shown in Figure 1 some embodiments, the guardrail includes a guard plate 1, two side rods 2, two bottom plates 3, and two tapered nails 5. The two sides of the guard plate 1 are fixedly connected with the side close to the two side rods 2, respectively. The top of the two bottom plates 3 is fixedly connected with the bottom of the two side rods 2, respectively. The two tapered nails 5 are fixedly connected with the bottom of the two bottom plates 3, respectively. The top of the guard plate 1 is fixedly connected with the rectangular plate 15.

[0050] The guard plate 1 is connected with the inner side of the two side poles 2 by welding or other fixing means as the main protection component, the two bottom plates 3 are fixed at the bottom of the two side poles 2 for stability, the conical nails 5 are fixed at the bottom of the bottom plates 3 for fixing the whole guard rail by inserting into the ground or other plane, and the top of the guard plate 1 is welded with a rectangular plate 15.

[0051] As shown in the drawings, in some embodiments, the guard rail further comprises two side plates 4 and a plurality of reflective strips 6, the two side plates 4 are fixedly connected with the side of the two bottom plates 3 away from each other, and the plurality of reflective strips 6 are arranged on the two sides of the guard plate 1. Figure 1

[0052] The user can press the side plates 4 to facilitate the conical nails 5 to insert into the ground or other plane, and the arrangement of the reflective strips 6 improves the visibility of the guard rail at night or in low light conditions, thereby increasing the safety.

[0053] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.​
