Description

Technical Field

[0001] The utility model relates to a protective facility, more specifically, it relates to a temporary protective facility. Background Art

[0002] During temporary construction, temporary protective facilities are usually required to be set up to alert surrounding pedestrians and vehicles, and to protect personal safety and equipment facilities to a certain extent. In the prior art, temporary protective facilities usually use expansion bolts as the medium for connecting components, but in actual construction, it is found that expansion bolts cannot be used in a cyclical manner, and temporary protective facilities need to be dismantled and modified at any time during the formal construction of the project, and need to be dismantled again after the formal project is completed, but expansion bolts cannot be dismantled, and can only be used once, which leads to serious waste. In addition, expansion bolts are difficult to remove, and the remaining expansion bolts may hinder the reuse of temporary protective facilities. In practice, the expansion bolts must be removed by flame cutting or other methods. This method is time-consuming and labor-intensive, and there are safety hazards. Therefore, a temporary protective facility is needed, which can be quickly disassembled and assembled, and is easy to transfer and reuse.

[0003] In view of the above reasons, how to quickly disassemble and assemble is exactly the problem considered in this application. Utility Model Content

[0004] In view of the shortcomings of the prior art, a temporary protective facility is provided, which can be quickly disassembled and assembled, and is convenient for transfer and reuse.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: temporary protective facilities, including a blocking plate, the blocking plate is connected to a first pin symmetrically arranged at both ends of the blocking plate, the first pin is connected to a support column, the first pin includes a first support member fixedly connected to the blocking plate, the first support member is fixedly connected to a limiting ring with an axis centerline perpendicular to the ground, the support column is fixedly connected to a second support member, the second support member is fixedly connected to a hollow cylinder with an axis centerline perpendicular to the ground, the inner diameter of the limiting ring is the same as the inner diameter of the hollow cylinder, and the limiting ring is also slidably connected to a connector slidably connected to the hollow cylinder and with the axis centerline perpendicular to the ground.

[0006] In summary, the above technical solution has the following beneficial effects: usually, in order to maintain the stability of the temporary protective facilities when they are impacted, expansion screws are used to fix the blocking plate and the support column in all directions, but this makes the temporary protective facilities lose flexibility, and in actual use, it is found that the impact on the blocking plate is mainly lateral impact, that is, most of the impact force received is concentrated in the direction parallel to the ground, so a plug-in with an axial centerline perpendicular to the ground is set as the force-bearing body, and a combination limit is performed by inserting a limit ring and a hollow cylinder, and the axial centerlines of the limit ring and the hollow cylinder are further perpendicular to the ground, so that the plug-in method is more secure, and because the actual plug-in direction is perpendicular to the maximum force direction of the impact force received, it will not fall apart due to the impact;

[0007] In addition, the expansion screw is usually tightly connected to the junction of the blocking plate and the support column, so that the three form an inseparable whole. When the impact force is too large, the damage of the expansion screw will drive the junction of the blocking plate and the support column to be damaged together. The utility model adopts an open connection structure, so even if the impact force is too large, it will be concentrated on the plug-in connector, which will only cause the plug-in connector to break without damaging the limit ring and the hollow cylinder. Only the low-cost plug-in connector needs to be replaced to quickly restore the temporary protection facility;

[0008] The utility model adopts a limit ring, a hollow cylinder and a connector combination whose axis center line is perpendicular to the ground. The assembly can be completed by directly inserting the connector into the limit ring and the hollow cylinder, thereby achieving rapid disassembly and assembly, and facilitating transfer and reuse.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] Reference Figure 1-3 As shown, the temporary protection facility includes a blocking plate 1, the blocking plate 1 is connected to a first latch 2 symmetrically arranged at both ends of the blocking plate 1, the first latch 2 is connected to a support column 21, the first latch 2 includes a first support member 22 fixedly connected to the blocking plate 1, the first support member 22 is fixedly connected to a limiting ring 23 with an axial center line perpendicular to the ground, the support column 21 is fixedly connected to a second support member 24, the second support member 24 is fixedly connected to a hollow cylinder 25 with an axial center line perpendicular to the ground, the inner diameter of the limiting ring 23 is the same as the inner diameter of the hollow cylinder 25, and the limiting ring 23 is also slidably connected to a plug-in member 26 slidably connected to the hollow cylinder 25 and with an axial center line perpendicular to the ground;

[0019] Usually, in order to maintain the stability of the temporary protective facilities when they are impacted, expansion screws are used to fix the blocking plate 1 and the support column 21 in all directions. However, this makes the temporary protective facilities lose flexibility. In actual use, it is found that the impact on the blocking plate 1 is mainly lateral impact, that is, most of the impact force received is concentrated in the direction parallel to the ground. Therefore, a plug-in connector 26 with an axial centerline perpendicular to the ground is set as the force-bearing body, and a combination limit is performed by inserting a limit ring 23 and a hollow cylinder 25, and further the axial centerlines of the limit ring 23 and the hollow cylinder 25 are perpendicular to the ground, so that the plug-in method is more secure, and because the actual plug-in direction is perpendicular to the maximum force direction of the impact force received, it will not fall apart due to the impact;

[0020] In addition, the expansion screw is usually tightly connected to the junction of the blocking plate 1 and the support column 21, so that the three form an inseparable whole. When the impact force is too large, the damage of the expansion screw will drive the junction of the blocking plate 1 and the support column 21 to be damaged together. The utility model adopts an open connection structure, so even if the impact force is too large, it will be concentrated on the plug connector 26, so that only the plug connector 26 will be broken, and the limit ring 23 and the hollow cylinder 25 will not be damaged. Only the low-cost plug connector 26 needs to be replaced to quickly restore the temporary protection facility;

[0021] The utility model adopts a combination of a limit ring 23, a hollow cylinder 25 and a connector 26 with an axial centerline perpendicular to the ground. The connector 26 can be assembled by directly inserting the limit ring 23 and the hollow cylinder 25, thereby achieving rapid disassembly and assembly, and facilitating transfer and reuse.

[0022] Furthermore, the connector 26 includes a pin shaft 261 and a pin head 262 fixedly connected to the pin shaft 261. The inner diameter of the pin shaft 261 is the same as the inner diameter of the hollow cylinder 25. The pin head 262 is cylindrical and has an outer diameter that is the same as the outer diameter of the limiting ring 23. The outer diameter of the pin head 262 is 14 mm, and the length of the pin shaft 261 is 60 mm.

[0023] Further, the pin shaft 261 is detachably connected with a split pin 27 disposed below the hollow cylinder 25, and the pin shaft 261 is also provided with a through hole 263 for accommodating the split pin 27, and the split pin 27 includes a pull ring 271, and the pull ring 271 is fixedly connected with two plug-in posts 272 symmetrically disposed up and down, and the plug-in posts 272 are fixedly connected with a limiting post 273 vertically disposed on the plug-in posts 272, and the two limiting posts 273 are symmetrically disposed, and the length of the limiting posts 273 in the vertical direction is less than the inner diameter of the through hole 263, and the sum of the lengths of the two limiting posts 273 in the vertical direction is greater than the inner diameter of the through hole 263;

[0024] The cotter pin 27 can further prevent the connector 26 from detaching. The pull ring 271 and the plug-in column 272 need to be made of a material with a certain toughness. When in use, the two limit columns 273 need to be pressed to make the two plug-in columns 272 misaligned and crossed, so that the two limit columns 273 can overlap in the vertical direction, thereby passing through the through hole 263, and then the two limit columns 273 are loosened to reset the two plug-in columns 272. At this time, the two limit columns 273 will also be reset, and the sum of the lengths of the two limit columns 273 in the vertical direction is greater than the inner diameter of the through hole 263, which can prevent the cotter pin 27 from detaching from the through hole 263.

[0025] Furthermore, the inner diameter of the through hole 263 is 4 mm, and the length of the plug-in column 272 is 8 mm.

[0026] Furthermore, a blocking net 3 is fixedly connected above the blocking plate 1, and the blocking net 3 is also connected to second latches 4 symmetrically arranged at both ends of the blocking net 3 and connected to the support column 21, and the internal structure of the second latch 4 is the same as that of the first latch 2;

[0027] For regulatory purposes, a barrier net 3 is also required to facilitate workers to observe the construction status in a timely manner. Since solid construction materials cannot be blown up, a blocking plate 1 is set under the barrier net 3 to prevent some small solid construction materials from rolling out of the construction site through the mesh.

[0028] Furthermore, the hollow cylinder 25 is made of a galvanized pipe, the wall thickness of the hollow cylinder 25 is 2 mm, and the length is 20 mm. The hollow cylinder 25 is connected to the support column 21 by double-sided welding.

[0029] Furthermore, the support column 21 is also fixedly connected to a fixing plate 211 , and the fixing plate 211 is provided with four mounting holes 212 with an inner diameter of 8 mm.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
