[0028] In view of the problems in the prior art, the utility model provides a kind of collapsible building construction safety protective fence, including support plate 1, the outside of support plate 1 is provided with two rollers 2, the side of support plate 1 close to each roller 2 is provided with rotating mechanism, each rotating mechanism includes accommodating groove 3, adjusting rod 4, adjusting block 5, passageway 6, limit screw 7 and locking thread hole 8, accommodating groove 3 is opened in the outside of support plate 1, adjusting rod 4 is rotatably connected in the inside of accommodating groove 3, adjusting block 5 is fixedly installed at the one end of adjusting rod 4 and passes through accommodating groove 3 to the outside of support plate 1, passageway 6 is opened in the outside of adjusting block 5, limit screw 7 is rotatably connected in the inside of passageway 6, locking thread hole 8 has two, two locking thread holes 8 are opened in the outside of support plate 1, limit screw 7 is screwedly connected in the inside of locking thread hole 8, locking thread hole 8 is below adjusting block 5, roller 2 is arranged in the outside of adjusting rod 4, by setting limit screw 7, cooperate adjusting rod 4, remove the connection of limit screw 7 and locking thread hole 8, at this time, when rotating roller 2, roller 2 rotates to the other end of support plate 1, at this time, adjusting block 5 rotates until another locking thread hole 8 is above, at this time, rotating limit screw 7 makes limit screw 7 and corresponding locking thread hole 8 connect and fix adjusting rod 4, at this time, roller 2 cannot rotate, the movable design of roller 2 effectively avoids the interference of roller 2 to the connection operation of protective fence, so that protective fence can be closely and smoothly connected, and the protection effect of protective fence is guaranteed.

[0029] The inside of each accommodating groove 3 is provided with a connecting hole 9, and a rotating shaft 10 is rotatably connected in the inside of the connecting hole 9.

[0030] The outside of each roller 2 is provided with a mounting groove 11, and the adjusting rod 4 is clamped in the inside of the mounting groove 11.

[0031] The outside of each adjusting rod 4 is provided with a threaded groove 12, and a fixed screw rod 13 is rotatably connected to the side of each roller 2 close to the adjusting rod 4, and the fixed screw rod 13 is screwedly connected in the inside of the threaded groove 12.

[0032] The side of each adjusting rod 4 close to the adjusting block 5 is provided with a limiting rod 14 for limiting the limit screw 7, and the outside of each adjusting rod 4 is provided with a moving groove 15, and the limiting rod 14 is slidably connected in the inside of the moving groove 15.

[0033] The interior of each mobile slot 15 is fixedly connected with a spiral spring 16, and the limiting rod 14 is fixedly connected outside the spiral spring 16.

[0034] Both ends of the support plate 1 are provided with a baffle 17 for limiting the limiting rod 14, and both ends of the support plate 1 are fixedly installed with a guide plate 18, which is a concave body. The baffle 17 is slidingly connected outside the guide plate 18.

[0036] The support plate 1 serves as the support structure of the entire protective fence, bearing other components. The roller 2 facilitates the movement of the protective fence on the construction site, reduces the labor intensity of manual carrying, and improves the construction efficiency.

[0037] The accommodating slot 3 provides installation space for the adjusting rod 4, so that the adjusting rod 4 can rotate freely in the accommodating slot 3, realizing the change of the position of the roller 2.

[0038] The adjusting block 5 facilitates the operation of the adjusting rod 4 and provides an installation position for the limiting screw rod 7. The adjusting rod 4 is driven to rotate by the rotation of the adjusting block 5. The channel 6 is used to install the limiting screw rod 7. The limiting screw rod 7 realizes the locking of the adjusting block 5 and the adjusting rod 4 by cooperating with the locking threaded hole 8.

[0039] By rotating the shaft 10 in the connecting hole 9, it is ensured that the adjusting rod 4 can rotate in the accommodating slot 3 without falling out of the interior of the accommodating slot 3.

[0040] The installation slot 11 provides an installation position for the adjusting rod 4, so that the roller 2 can be connected with the adjusting rod 4, and the roller 2 is firmly fixed on the adjusting rod 4 through the threaded connection of the fixed screw rod 13 and the threaded slot 12, reducing the probability of falling off of the roller 2 during use.

[0041] The limiting rod 14 is used to limit the rotation of the limiting screw rod 7, preventing the accidental loosening of the limiting screw rod 7 when it is not needed to rotate the roller 2. The mobile slot 15 provides a moving space for the limiting rod 14, so that it can move up and down in the slot, realizing the limitation and release of the limiting screw rod 7. The spiral spring 16 provides an elastic force, so that the limiting rod 14 can automatically reset when not subjected to external force and fit outside the limiting screw rod 7, playing a limiting role.

[0042] When the roller 2 needs to be rotated, the baffle 17 blocks the downward movement of the limiting rod 14, so that the limiting screw rod 7 can be smoothly rotated, the position of the roller 2 is adjusted, the guide plate 18 provides movement guide for the baffle 17, so that the baffle 17 can be stably moved below or away from the limiting rod 14, and the handle 19 facilitates the construction personnel to pull the baffle 17. The guide plate 18 can be regarded as three parts, two vertical plates and a horizontal plate. The baffle 17 is provided with a groove to be slidably connected outside the horizontal plate. Then, the two vertical plates are fixed at both ends of the horizontal plate, and then the two vertical plates are fixed outside the support plate 1. At this time, the baffle 17 is installed.

[0043] Working principle:

[0044] Firstly, the adjusting rod 4 is inserted into the inside of the installation groove 11. At this time, the fixed screw rod 13 is rotated to be connected with the threaded groove 12. At this time, the roller 2 is connected with the adjusting rod 4.

[0045] Secondly, when the two guardrails are connected, the limiting rod 14 is pulled upwards to be away from the limiting screw rod 7. At this time, the spiral spring 16 is stretched. At this time, the baffle 17 is pushed to move below the limiting rod 14. At this time, the limiting rod 14 is limited by the baffle 17 and cannot move downwards. At this time, the limiting screw rod 7 is rotated to be disconnected with the locking threaded hole 8. At this time, the roller 2 is rotated to the other side of the support plate 1. At this time, the adjusting block 5 is rotated to the other locking threaded hole 8. At this time, the limiting screw rod 7 is rotated to be connected with the locking threaded hole 8. At this time, the adjusting rod 4 is fixed. At this time, the baffle 17 is pushed to be away from the limiting rod 14. At this time, the limiting rod 14 is moved back under the action of the spiral spring 16. At this time, the limiting rod 14 is attached to the outside of the limiting screw rod 7.

[0046] Finally, it should be pointed out that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation mode. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation modes. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
