DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0025] Please refer to Figures 1-8 The present application provides an embodiment: an explosion-proof guardrail, comprising a plurality of identical protection pieces 12; the protection piece 12 comprises a first isolation piece 16 and a second isolation piece 17 movably mounted on the first isolation piece 16; the first isolation piece 16 comprises a bottom plate 1 and a fence plate 5; the bottom plate 1 is provided with a first shaft pin seat 7, and the lower portion of the fence plate 5 is further provided with a connecting plate 6, and the shaft pin rod 8 is provided to pass through the first shaft pin seat 7 and the connecting plate 6, so that one end of the fence plate 5 is rotatably mounted on the bottom plate 1; the upper portion of the fence plate 5 is further provided with a second shaft pin seat 9, and a first support rod 3 is mounted on the second shaft pin seat 9, and the other end of the first support rod 3 is connected with the third shaft pin seat 11 provided on the bottom plate 1.

[0026] In summary, the explosion-proof guardrail not only has the function of protection and enclosure, but also is easy to fold, so as to facilitate the rapid handling and transfer of the equipment; by increasing the height of the second isolation piece 17, the difficulty of climbing over the guardrail is increased, and the problem of equipment falling caused by artificial knocking down is avoided; therefore, compared with the existing technology such as steel wire mesh, the equipment has the advantages of strong protection, easy disassembly and assembly, and easy movement.

[0027] In addition, since the guard 12 can form a stable individual after unfolding, the device can effectively prevent pedestrians from climbing over the device and reduce the situation of the device being knocked down by people. Meanwhile, the device can be disassembled and moved, so as to effectively avoid the situation of driving pegs or pouring a base in the activity site, and avoid the situation of difficulty in recovering the site after the activity is over. Further, by rotating and folding, the volume of the device is reduced, so as to reduce the transportation and storage costs.

[0028] Further, the second support rod 4 is further arranged between the bottom plate 1 and the fence plate 5, so that the fence plate 5 can be supported by two support rods to improve the stability of the device after unfolding, and further improve the protection capability of the device.

[0029] Further, the bearing table 2 is rotatably arranged between the first support rod 3 and the second support rod 4, so as to provide a standing platform for the safety officer, and the bearing table 2 is rotatably arranged between the two support rods, so as not to affect the folding of the fence plate 5.

[0030] On the basis of the above-mentioned scheme, the supporting beam 10 for supporting the bearing table 2 is further arranged on the fence plate 5, so that when the fence plate 5 is unfolded, one end of the bearing table 2 is located between the two support rods, and the other end is placed on the supporting beam 10, thereby providing a more stable standing platform for the safety officer.

[0031] In addition, the first support rod 3 and the second support rod 4 are connected with the bottom plate 1 and the fence plate 5 in the following manner: a light rod bolt is connected with a nut after penetrating through the second shaft pin seat 9, so as to rotatably arrange one end of the first support rod 3 and the second support rod 4 on the fence plate 5; similarly, a light rod bolt is used to penetrate through the third shaft pin seat 11, so as to connect the first support rod 3 and the second support rod 4 with the bottom plate 1, and the shaft pin rod 8 is also preferably a light rod bolt; therefore, by disassembling the above-mentioned light rod bolt, the bottom plate 1, the fence plate 5, the first support rod 3, the second support rod 4 and the bearing table 2 constituting the guardrail can be disassembled and assembled with each other, so as to have the advantages of on-site assembly and on-site disassembly of the guardrail, thereby further improving the clearing efficiency of the guardrail.

[0032] On the basis of the above-mentioned scheme, the bottom of the second isolation piece 17 is provided with a clamping groove 18 clamped above the fence plate 5, so that the second isolation piece 17 can be smoothly connected with the fence plate 5, and the clamping groove 18 clamped on the fence plate 5 can improve the stability of the two isolation pieces after being connected.

[0033] Further, since the second partition 17 is connected with the first connecting seat 13 arranged on the fence plate 5 through the reinforcing plate 19, specifically, when the reinforcing plate 19 is connected with the first connecting seat 13, the light rod bolt is used to pass through both of them and is connected with the nut, so as to further improve the stability of the two partitions after being connected.

[0034] Since the second connecting seat 14 is arranged below the fence plate 5, when the side surfaces of the two guards 12 are attached, the light rod bolt is used to pass through the second connecting seat 14 on the two guards 12 and is connected with the nut, so as to further improve the stability between the side surfaces of the two guards 12.

[0035] As described above, all the connecting components of the explosion-proof guardrail are arranged on the back of the explosion-proof guardrail, that is, on the side facing the two support rods, so that the connecting parts can be prevented from being manually disassembled on the construction site, and the safety of the construction site is protected.

[0036] On the basis of the above-mentioned scheme, since the two ends of the bottom plate 1, the upper end of the fence plate 5 and the upper end of the second partition 17 are all provided with the connecting pin 20, when one guard 12 is connected with another guard 12, the connecting pin 20 can guide the smooth connection between the two guards.

[0037] Further, the connecting pin 20 comprises the bolt part 21, the guide rod 22, the borrowing pipe 23 which is screwed with the guide rod 22, and the locking part 24, and further, the opposite surfaces of the borrowing pipe 23 and the locking part 24 are both provided with inclined surfaces.

[0038] Therefore, before leaving the factory, the guide rod 22 is connected with the locking part 24 through the borrowing pipe 23, and then is placed in the guard 12, at this time, the guide rod 22 is rotated, and the locking part 24 slides along the inclined surface, so as to fix the connecting pin 20 in the guardrail, and the fixing of the connecting pin 20 is completed.

[0039] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications of the embodiments can be made without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
