[0022] (3) Beneficial effects

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In order to solve the problem, the current safety protection device for the edge opening of the building is mainly composed of a fixed structure guardrail, which is used to block the opening outside the building to prevent construction workers from accidentally falling during construction. Although the fixed structure guardrail can block and protect the opening outside the building, on the one hand, the blocking area of ​​the fixed structure guardrail cannot be flexibly adjusted according to the size of the building opening, resulting in poor flexibility of the safety protection device for the edge opening of the building when in use. On the other hand, the fixed structure guardrail is mostly assembled by splicing when in use, which makes the installation process of the device more cumbersome and inconvenient for efficient installation and use of the device. The utility model solves the problem by symmetrically installing two extended baffles in the blocking sleeve and installing an adjusting component between the extended baffles and the blocking sleeve, so that the safety protection device for the edge opening of the building can extend the extended baffles from the blocking sleeve under the action of the adjusting component when in use, so that the shielding protection area between the blocking sleeve and the extended baffles matches the size of the building opening, making the safety protection device for the edge opening of the building more flexible to use. At the same time, by reserving limiting edges at the ends of each extended baffle, the limiting edges can be pressed against the corners of the inner wall of the building opening when adjusting the extended baffle, thereby realizing rapid limiting of the device after adjusting the shielding area, and facilitating efficient installation and use of the device.

The adjustment component 6 includes a hand wheel 601, a rotating shaft 602, a gear 2 604, a screw 605, a gear 1 606, and a sliding cavity 603. When fully protected, first move the blocking sleeve 1 to the middle of the hole, and align the limiting edge 4 with the corners of the wall inside the hole, then turn the hand wheel 601 to rotate the rotating shaft 602, so that the screw 605 can be rotated under the action of gear 1 606 and gear 2 604. After the screw 605 rotates, the extended baffle 5 will slide out under the guidance of the thread transmission and the sliding cavity 603, until the limiting edge 4 is in contact with the corners of the wall inside the outer hole of the building and is tightened, then the device can be put into use.

[0033] like Figures 1-4 As shown, in this embodiment, the sliding cavity 603 is symmetrically opened in the blocking sleeve 1 and cooperates with the extension baffle 5, and a limiting shoulder is reserved on the end of the extension baffle 5 facing away from the limiting edge 4. The design of the limiting shoulder can effectively prevent the extension baffle 5 from completely sliding out of the sliding cavity 603, so as to ensure the connection strength between the extension baffle 5 and the blocking sleeve 1 after it is extended.

[0034] like Figures 1-4 As shown, in this embodiment, the rotating shaft 602 is rotatably installed in the middle of the blocking sleeve 1, and the top end of the rotating shaft 602 passes through the blocking sleeve 1 and is welded and fixed with the handwheel 601. Rotating the handwheel 601 can realize the convenient rotation adjustment of the rotating shaft 602 relative to the blocking sleeve 1. Gear 1 606 is installed in the middle of the rotating shaft 602. There are two gears 2 604. The two gears 2 604 are symmetrically meshed on both sides of the upper end of gear 1 606. After gear 1 606 rotates under the action of the rotating shaft 602, gear 2 604 can be conveniently rotated. There are two screws 605, and each screw 605 is welded to the corresponding gear 2 604. At the same time, each screw 605 is threadedly connected to the corresponding extension baffle 5. After the screw 605 rotates with the gear 2 604, the extension baffle 5 can be slid and adjusted along the sliding cavity 603 under the guidance of the thread transmission and the sliding cavity 603.

[0035] like Figure 1-Figure 3As shown, in this embodiment, the limiting edge 4 is welded to the extended baffle 5, and the width of the limiting edge 4 is the same as the width of the blocking sleeve 1.

The base 3 cooperates with the universal wheel 2 to realize the flexible movement of the blocking sleeve 1 when in use. The universal wheel 2 is equipped with a wheel brake, and the connecting frame on the universal wheel 2 is bolted to the base 3. The design of the wheel brake allows the universal wheel 2 to be flexibly braked according to actual needs when in use.

[0037] The specific implementation process of this embodiment is as follows: when in use, first move the blocking sleeve 1 to the middle of the hole, and align the limiting edge 4 with the corners of the wall inside the hole, then turn the hand wheel 601 to rotate the shaft 602, so that the screw 605 can be rotated under the action of gear 1 606 and gear 2 604. After the screw 605 rotates, the extension baffle 5 will slide out under the guidance of the thread transmission and the sliding cavity 603, until the limiting edge 4 is in contact with the corners of the wall inside the hole outside the building and is tightened, then the device can be put into use. During use, by symmetrically installing two extension baffles 5 in the blocking sleeve 1 and An adjusting component 6 is installed between the plate 5 and the blocking sleeve 1, so that when the safety protection device for the edge opening of the building is in use, the extended baffle 5 can be extended from the blocking sleeve 1 under the action of the adjusting component 6, so that the shielding protection area between the blocking sleeve 1 and the extended baffle 5 matches the size of the building opening, making the use of the safety protection device for the edge opening of the building more flexible. At the same time, by reserving a limiting edge 4 at the end of each extended baffle 5, the limiting edge 4 can be pressed against the corner of the inner wall of the building opening while adjusting the extended baffle 5, thereby realizing rapid limiting of the device after adjusting the shielding area, facilitating efficient installation and use of the device.
