DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] The components in the present case are sequentially connected by those skilled in the art, and the specific connection and operation sequence should be referred to the following working principle. The detailed connection means is the commonly known technology in the art, and the following mainly introduces the working principle and process.

[0024] At present, when the building fence is transported, because the building fence adopts an integrated design, the building fence cannot be folded, and a large space area is occupied during transportation, so the building fence needs to be transported in batches, which increases the transportation cost of the building fence;

[0025] Therefore, the building fence with an auxiliary positioning structure is provided, which can be folded before being transported by workers, so that the land occupation area of the building fence is reduced, more building fences can be transported at one time, the transportation frequency of the building fence is reduced, and the transportation cost of the building fence is effectively reduced.

[0026] Embodiment one: by Figure 1 , 2 , 3, 4, 5 and 8, a building fence with an auxiliary positioning structure, comprising a first base 1, a second base 8 is arranged on one side of the first base 1, a first top plate 6 is arranged above the first base 1, a second top plate 7 is arranged above the second base 8, an auxiliary positioning device 4 is arranged above the first base 1 and the second base 8, and a folding device 2 is arranged between the first base 1 and the second base 8 and the first top plate 6 and the second top plate 7, the folding device 2 comprises: a plurality of support plates 21, which are fixedly connected to the top of the first base 1 and the second base 8; a plurality of cavities 22, which are arranged above the plurality of support plates 21; a plurality of vertical plates 23, which are inserted into the internal cavities 22 of the plurality of support plates 21 and are fixedly connected to the bottom of the first top plate 6 and the second top plate 7; a plurality of first horizontal rods 24, which are rotatably connected to the top of the cavities 22 of the plurality of support plates 21 through bearings and are fixedly connected to the bottom of the plurality of vertical plates 23; and a limiting mechanism 25, which is arranged above the support plates 21 on both sides of the first base 1 and the second base 8; wherein, after the limiting mechanism 25 is released, the worker pulls the first top plate 6 and the second top plate 7, which drives the plurality of vertical plates 23 to rotate along the inner walls of the plurality of support plates 21, so as to fold the building fence;

[0027] In the specific implementation process, it is particularly worth pointing out that when the worker folds the building fence, the limiting mechanism 25 is first released, then the worker pulls the first top plate 6 and the second top plate 7, at the same time, the plurality of vertical plates 23 begin to be stressed and rotate along the internal cavities 22 of the plurality of support plates 21 through the plurality of first horizontal rods 24, until the worker rotates the plurality of vertical plates 23 to the appropriate position, at this time, the plurality of vertical plates 23 are retracted into the internal cavities 22 of the plurality of support plates 21, and the land occupation area between the plurality of vertical plates 23 and the plurality of support plates 21 is reduced after folding, and finally the worker limits the plurality of vertical plates 23 and the plurality of support plates 21 by opening the limiting mechanism 25.

[0028] Further, the limiting mechanism 25 comprises: a plurality of second horizontal rods 251, rotatably connected to the inner wall above the plurality of supporting plates 21 on the top of the first base 1 and the second base 8 respectively, and fixedly connected to the bottom of the plurality of vertical plates 23 on both sides of the bottom of the first top plate 6 and the second top plate 7 respectively; a plurality of polygonal vertical plates 252, arranged at both ends of the second horizontal rods 251, and fitted to the outer wall above the plurality of supporting plates 21 on both sides of the top of the first base 1 and the second base 8 respectively; a plurality of grooves 253, machined on the inner wall above the plurality of supporting plates 21 on the top of the first base 1 and the second base 8 respectively; a plurality of limiting plates 254, inserted into the grooves 253 of the plurality of supporting plates 21 respectively; a plurality of springs 255, sleeved on the outer wall of the plurality of limiting plates 254 respectively, and abutting against the inner grooves 253 of the plurality of supporting plates 21 at one end, and abutting against the outer wall of the plurality of limiting plates 254; a plurality of supporting rods 256, rotatably connected to the outer wall of the plurality of limiting plates 254 by a pin; and a plurality of limiting blocks 257, fixedly connected to the outer wall of the plurality of limiting plates 254. When the plurality of limiting plates 254 are separated from the outer wall of the plurality of polygonal vertical plates 252, the plurality of springs 255 are compressed along the inner grooves 253 of the plurality of supporting plates 21, and then the plurality of vertical plates 23 are rotated to fold the plurality of second horizontal rods 251 into the inner cavities 22 of the plurality of supporting plates 21.

[0029] In specific implementation process, it is worth pointing out that, after opening the limiting mechanism 25, the plurality of polygonal vertical plates 252 and the plurality of second cross bars 251 are limited, at this time, the plurality of vertical plates 23 on both sides of the first base 1 and the second base 8 can no longer rotate along the internal cavity 22 of the plurality of supporting plates 21 through the plurality of second cross bars 251, the number of edges of the plurality of polygonal vertical plates 252 is not limited, which meets the use requirement, when the plurality of limiting plates 254 limit the edges of the plurality of polygonal vertical plates 252 at different positions, the folding angle between the plurality of vertical plates 23 and the plurality of supporting plates 21 can be changed, so that the folding angle of the building fence can be changed, the workers need to replace the plurality of springs 255 regularly, so as to avoid the decrease of the elastic potential of the plurality of springs 255 after long time use, the bottom of the plurality of supporting rods 256 is arc-shaped, when it is needed to remove the limiting mechanism 25, the workers can rotate the plurality of supporting rods 256 through the pin shaft, until the bottom arc of the plurality of supporting rods 256 abuts against the outer wall of the plurality of supporting plates 21, since the length of the plurality of supporting rods 256 is greater than the distance between the outer wall of the plurality of limiting plates 254 and the outer wall of the plurality of supporting plates 21 when the limiting mechanism 25 is opened, the plurality of limiting plates 254 will be separated from the outer wall of the plurality of polygonal vertical plates 252, so that the limiting mechanism 25 can be removed, the plurality of limiting blocks 257 can limit the plurality of supporting rods 256, so as to prevent the plurality of supporting rods 256 from being separated from the outer wall of the plurality of supporting plates 21 under the influence of external force when the plurality of supporting rods 256 abut against the outer wall of the plurality of supporting plates 21;

[0030] Specifically, when the construction fence with the auxiliary positioning structure is used, when the worker wants to fold the construction fence, first, the worker removes the limit of one side of the construction fence on one side of the first top plate 6, pulls the two limiting plates 254 away from the two polygonal vertical plates 252, at this time, the two limiting plates 254 start to move along the outer walls of the two polygonal vertical plates 252, and at the same time, the two limiting plates 254 will move along the inner grooves 253 of the support plate 21, at this time, the plurality of springs 255 will be compressed due to the movement of the two limiting plates 254, until the two limiting plates 254 are separated from the outer walls of the two polygonal vertical plates 252, the worker rotates the support rod 256 along the outer wall of the two limiting plates 254 in turn through the pin shaft, until the bottom arc of the plurality of support rods 256 is tightly abutted with the outer wall of the support plate 21, at this time, the plurality of support rods 256 will limit the two limiting plates 254, so that the two limiting plates 254 cannot limit the two polygonal vertical plates 252 again, the removal of the limit of the other side of the construction fence is the same as the above, until the worker removes the limit of both sides of the construction fence, the worker pulls the first top plate 6, at this time, the first top plate 6 will drive the plurality of vertical plates 23 to start rotating along the inner cavities 22 of the plurality of support plates 21 through the first horizontal rod 24 and the second horizontal rod 251, when the worker rotates the plurality of vertical plates 23 to the appropriate angle, then restores the limit of one side of the construction fence on one side of the first top plate 6, at this time, the worker reversely rotates the support rod 256 along the outer wall of the two limiting plates 254 in turn through the pin shaft, until the bottom arc of the plurality of support rods 256 is separated from the outer wall of the support plate 21, at this time, the plurality of support rods 256 no longer limit the two limiting plates 254, and at the same time, the plurality of springs 255 no longer force the original state, and drive the two limiting plates 254 to move towards the two polygonal vertical plates 252, until the inner walls of the two limiting plates 254 are connected with the outer walls of the two polygonal vertical plates 252, the two limiting plates 254 start to limit the two polygonal vertical plates 252, at this time, the vertical plates 23 on one side of the first base 1 and the second base 8 can no longer rotate along the inner cavities 22 of the support plate 21 through the second horizontal rod 251, the restoration of the limit of the other side of the construction fence is the same as the above, until the worker restores the limit of both sides of the construction fence, at this time, the construction fence on one side of the first top plate 6 cannot be rotated again, the opening and removal of the limit of the construction fence on one side of the second top plate 7 is the same as the above.

[0031] Embodiment two: by Figure 1 、 2As shown in FIGS. 6 and 7, the first roof 6 and the lower part of the second roof 7 are provided with the fixing device 3, which comprises: two housings 31, the outer wall of the housing 31 near the first roof 6 is fixedly connected to the outer wall above the vertical plate 23 near the second roof 7 and fixedly connected to the bottom of the first roof 6, and the outer wall of the housing 31 away from the first roof 6 is fixedly connected to the outer wall above the vertical plate 23 away from the first roof 6 and fixedly connected to the bottom of the second roof 7; two threaded rods 33, the outer wall of the threaded rod 33 near the first roof 6 is fixedly connected to the outer wall above the vertical plate 23 away from the second roof 7 and fixedly connected to the bottom of the first roof 6, and the outer wall of the threaded rod 33 away from the first roof 6 is fixedly connected to the outer wall above the vertical plate 23 near the first roof 6 and fixedly connected to the bottom of the second roof 7; two vertical pipes 32, which are respectively rotatably connected to the inner wall of the two housings 31 through bearings, and the outer wall of the vertical pipe 32 near the first roof 6 is sleeved with the outer wall of the threaded rod 33 near the second roof 7; two nuts 34, which are respectively threadedly connected to the outer wall below the two threaded rods 33, and the outer wall of the nut 34 away from the first roof 6 abuts against the bottom of the vertical pipe 32 near the first roof 6; wherein, after the worker inserts the threaded rod 33 into the inner wall of the vertical pipe 32, the worker tightens the nut 34 and the threaded rod 33 to complete the fixing, and the housing 31 rotates along the outer wall of the vertical pipe 32 through the bearing when it is stressed;

[0032] In the specific implementation process, it is particularly worth noting that the angle between the two building fences on one side of the first roof 6 and one side of the second roof 7 can be adjusted. When it is necessary to adjust the angle of the two building fences, the worker rotates the building fence on one side of the first roof 6. At this time, the housing 31 near the first roof 6 begins to rotate along the outer wall of the vertical pipe 32 near the first roof 6 through the bearing until the building fence on one side of the first roof 6 is rotated to the appropriate position. The worker stops rotating the building fence on one side of the first roof 6. At this time, the angle between the building fence on one side of the first roof 6 and the building fence on one side of the second roof 7 changes, thereby completing the angle adjustment operation between the two building fences on one side of the first roof 6 and one side of the second roof 7.

[0033] Specifically, on the basis of the above embodiment one, when the worker wants to splice and fix the building fence on one side of the second roof 7 with the building fence on one side of the first roof 6, the worker first lifts the building fence on one side of the second roof 7, then inserts the threaded rod 33 near the second roof 7 into the inner wall of the vertical pipe 32 near the first roof 6, until the threaded rod 33 near the second roof 7 passes through the inner wall of the vertical pipe 32 near the first roof 6, the worker tightens the nut 34 and the threaded rod 33 near the second roof 7, thereby completing the splicing and fixing operation of the two building fences on one side of the first roof 6 and one side of the second roof 7.

[0034] Embodiment three: from Figure 1 , 2 and 7, the auxiliary positioning device 4 includes: two horizontal plates 41, which are arranged below the two housings 31, the outer wall of the horizontal plate 41 near the first base 1 is fixedly connected to the lower outer wall of the support plate 21 near the second base 8 and fixedly connected to the top of the first base 1, and the outer wall of the horizontal plate 41 near the second base 8 is fixedly connected to the lower outer wall of the support plate 21 away from the first base 1 and fixedly connected to the top of the second base 8; two auxiliary pipes 42, which are rotatably connected to the inner walls of the two horizontal plates 41 through bearings; two insertion rods 43, which are respectively inserted into the inner walls of the two auxiliary pipes 42, and the outer wall of the insertion rod 43 away from the second base 8 is fixedly connected to the lower outer wall of the support plate 21 away from the second base 8 and fixedly connected to the top of the first base 1, and the outer wall of the insertion rod 43 near the second base 8 is fixedly connected to the lower outer wall of the support plate 21 near the first base 1 and fixedly connected to the top of the second base 8; wherein the auxiliary pipe 42 drives the insertion rod 43 to rotate along the inner wall of the horizontal plate 41 through the bearing when it is stressed;

[0035] In the specific implementation process, it is particularly worth noting that the top width of the two auxiliary pipes 42 is greater than the bottom width, so that when the worker inserts the insertion rod 43 into the inner wall of the auxiliary pipe 42 from the top of the auxiliary pipe 42, it is not necessary to spend a lot of time to align the top opening of the auxiliary pipe 42, thereby playing an auxiliary positioning role in the splicing of the building fence, when the angle between the two building fences on one side of the first top plate 6 and one side of the second top plate 7 is adjusted, because the housing 31 near the first top plate 6 will rotate along the outer wall of the vertical pipe 32 near the first top plate 6 through the bearing, thereby causing the auxiliary pipe 42 near the first top plate 6 to rotate along the inner wall of the horizontal plate 41 near the first top plate 6 through the bearing, because the insertion rod 43 near the second top plate 7 is inserted into the auxiliary pipe 42 near the first top plate 6, so that the auxiliary pipe 42 near the first top plate 6 will not be affected when it rotates along the inner wall of the horizontal plate 41 near the first top plate 6 through the bearing;

[0036] Specifically, on the basis of the above embodiment one, before the worker inserts the threaded rod 33 near the second top plate 7 into the inner wall of the vertical pipe 32 near the first top plate 6, the worker first lifts the building fence near the second top plate 7 side, and then inserts the insertion rod 43 near the second top plate 7 side into the top of the auxiliary pipe 42 near the first top plate 6 side. Because the width of the top of the auxiliary pipe 42 is greater than the width of the insertion rod 43, the worker can easily put the insertion rod 43 into the top of the auxiliary pipe 42. As the insertion rod 43 continuously penetrates into the bottom of the auxiliary pipe 42, the inner wall of the auxiliary pipe 42 begins to gradually narrow until the lower side of the outer wall of the insertion rod 43 is in contact with the lower side of the inner wall of the auxiliary pipe 42, and the bottom of the threaded rod 33 near the second top plate 7 side is aligned with the middle opening of the vertical pipe 32 near the first top plate 6 side. When the insertion rod 43 near the second top plate 7 side continues to move downward and penetrates through the bottom of the auxiliary pipe 42 near the first top plate 6 side, the threaded rod 33 near the second top plate 7 side is simultaneously inserted into the inner wall of the vertical pipe 32 near the first top plate 6 side. Until the support plate 21 of the building fence near the second top plate 7 side contacts the ground, the threaded rod 33 near the second top plate 7 side and the insertion rod 43 stop moving, and the auxiliary positioning operation of the fixing device 3 is completed.

[0037] Embodiment four: from Figure 1 、 2 and 8, the first base 1 and the second base 8 are provided with a protective device 5, the protective device 5 comprises: a plurality of iron nets 51, which are respectively fixedly connected to the lower side of the outer wall of the plurality of support plates 21 through bolts, and are respectively fixedly connected to the upper side of the outer wall of the plurality of vertical plates 23 through bolts; two warning signs 52 are respectively fixedly connected between the plurality of iron nets 51 through bolts; wherein the iron net 51 plays an intercepting role for pedestrians, and the warning sign 52 plays a prompting role for pedestrians;

[0038] In the specific implementation process, it is particularly worth pointing out that when the iron net 51 is damaged, the worker can remove the damaged iron net 51 from between the two support plates 21 or between the two vertical plates 23 by loosening the bolts, and then fix the new iron net 51 between the two support plates 21 or between the two vertical plates 23 with bolts;

[0039] Specifically, on the basis of the above embodiment one, when pedestrians approach the building fence, the plurality of iron nets 51 can block the pedestrians to prevent them from entering the protection area, and the worker can mark text on the two warning signs 52, which can prompt pedestrians to pay attention to safety.
