Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figures 1 to 6 As shown, this utility model provides a safety frame for building construction, including a base frame 1. A rear guardrail 2 is provided on the top surface of the base frame 1. A left guardrail 3 and a right guardrail 4 are respectively provided on opposite sides of the rear guardrail 2. The rear guardrail 2, left guardrail 3, and right guardrail 4 are all fence-like structures and are distributed in a U-shape. A movable guardrail 5 is hinged to the end of the right guardrail 4 away from the rear guardrail 2. A locking bar groove 6 is provided at the end of the left guardrail 3 away from the rear guardrail 2. A locking bar assembly 61 and a magnet block 62 are arranged sequentially from top to bottom in the locking bar groove 6. The locking bar assembly 61 and the magnet block 62 are magnetically attracted to each other. A rod slot 51 adapted to the locking bar assembly 61 is provided at the end of the movable guardrail 5 away from the right guardrail 4. The locking bar assembly 61 is movable at the end away from the locking bar groove 6. An extension railing assembly 7 is movably mounted on the top surfaces of the rear railing 2, left railing 3, and right railing 4, inserted into the rod slot 51. In use, the movable railing 5 can be opened by rotating the right railing 4. After the operator enters the bottom frame 1, the movable railing 5 can be closed. At this time, the end of the locking rod assembly 61 away from the locking rod groove 6 can be inserted into the rod slot 51. The locking rod assembly 61 and the magnet 62 are magnetically attracted, which helps prevent the locking rod assembly 61 from loosening in the locking rod groove 6, and thus prevents the end of the locking rod assembly 61 away from the locking rod groove 6 from falling out of the rod slot 51, improving safety. The extension railing assembly 7 can also be moved away from the top surfaces of the rear railing 2, left railing 3, and right railing 4 as needed, thereby adjusting the protective height within the safety frame for construction. Example

[0022] Based on Example 1, such as Figures 1 to 3 , Figures 5 to 6As shown, a slot 31 is provided on the top of the side wall of the left railing 3 away from the rear railing 2. A locking plate 32 adapted to the slot 31 is provided on the end of the movable railing 5 away from the right railing 4. The locking plate 32 is movably locked in the slot 31. The rod slot 51 penetrates the locking plate 32 vertically. The locking rod assembly 61 includes a fixing plate 611 horizontally disposed in the locking rod groove 6. A locking rod 612 is movably disposed on the fixing plate 611 and is perpendicular to the fixing plate 611. A magnetic disk 613 magnetically attracts the magnet block 62 at the lower end of the locking rod 612. The magnet block 62 is disposed on the bottom surface of the locking rod groove 6. An inverted U-shaped rod 615 is provided at the upper end of the locking rod 612. One end of the U-shaped opening of the inverted U-shaped rod 615 is connected to the upper end of the locking rod 612. The rod slot 51 is disposed on the locking plate 32 and is perpendicular to the U-shaped opening of the inverted U-shaped rod 615. The other end of the opening is adapted, and a through groove 616 corresponding to the position of the rod slot 51 is provided on the top surface of the slot 31. The other end of the U-shaped opening of the inverted U-shaped rod 615 moves through the rod slot 51 into the through groove 616. When the movable panel 5 is closed, the locking plate 32 on the movable panel 5 can be locked into the slot 31 on the left panel 3. At this time, the other end of the U-shaped opening of the inverted U-shaped rod 615 can be inserted through the rod slot 51 into the through groove 616 (at the same time, the lower end of the locking rod 612 moves towards the magnet block 62 in the locking rod groove 6), so that the movable panel 5 and the left panel 3 are connected. At the same time, the magnetic disk 613 and the magnet block 62 are magnetically attracted, which helps to keep the position of the locking rod 612 stable and prevents the other end of the U-shaped opening of the inverted U-shaped rod 615 from falling out of the through groove 616, thus improving safety.

[0023] A return spring 614 is provided on the bottom surface of the fixing plate 611. The return spring 614 is sleeved on the outside of the locking rod 612, and the end of the return spring 614 away from the fixing plate 611 is connected to the locking rod 612. Under the action of the return spring 614, it is beneficial to keep the locking rod 612 in the locking rod groove 6 (that is, to keep the lower end of the locking rod 612 close to the magnet block 62), thereby preventing the other end of the U-shaped opening of the inverted U-shaped rod 615 from loosening and detaching from the through groove 616.

[0024] A handle 6151 is provided at the top of the inverted U-shaped rod 615; this allows the operator to hold the handle 6151 to adjust the position of the inverted U-shaped rod 615, that is, to pass the other end of the U-shaped opening of the inverted U-shaped rod 615 through the rod slot 51 and insert it into the through groove 616 to close the movable panel 5, or to pull the other end of the U-shaped opening of the inverted U-shaped rod 615 out from the rod slot 51 and the through groove 616 to open the movable panel 5. Example

[0025] Based on Example 1, such as Figure 1 , Figures 3 to 4As shown, the extension rail assembly 7 includes a U-shaped extension rod 71, which is movably disposed on the top surface of the rear rail 2, left rail 3, and right rail 4, with the U-shaped opening of the extension rod 71 facing the movable rail 5. Multiple adjusting rods 72 are disposed on the bottom surface of the U-shaped extension rod 71, and the adjusting rods 72 respectively movably penetrate into the rear rail 2, left rail 3, and right rail 4. Multiple fastening bolts 73, corresponding one-to-one with the adjusting rods 72, are also threaded onto the top inner walls of the rear rail 2, left rail 3, and right rail 4. Multiple internal threaded holes 74, adapted to the fastening bolts 73, are spaced along the length of the adjusting rods 72, and the fastening bolts 73 are respectively connected to the corresponding positions of the fastening bolts 73. The internal threaded hole 74 is threaded for connection. When it is necessary to adjust the protective height inside the safety frame for construction of this building, the fastening bolt 73 can be loosened first, and then the U-shaped extension rod 71 can be moved away from the top surface of the rear railing 2, left railing 3 and right railing 4. The adjusting rod 72 can be moved synchronously (at this time, the distance from the U-shaped extension rod 71 to the top surface of the rear railing 2, left railing 3 and right railing 4 increases). Then, the fastening bolts 73 on the top inner wall of the rear railing 2, left railing 3 and right railing 4 are threaded to the corresponding internal threaded holes 74 on the adjusting rod 72, so that the U-shaped extension rod 71 and the adjusting rod 72 can be fixed, thereby adjusting the protective height inside the safety frame for construction of this building.

[0026] Since the rear panel 2, left panel 3, and right panel 4 are all fence-like structures, the adjusting rod 72 can be moved through the gaps in the rear panel 2, left panel 3, and right panel 4. When the U-shaped extension rod 71 is moved to the top surface of the rear panel 2, left panel 3, and right panel 4, the adjusting rod 72 can then pass through the corresponding gaps in the rear panel 2, left panel 3, and right panel 4, thereby reducing the size of the gaps. This prevents smaller tools or other items placed in the safety frame for construction from falling through the gaps in the rear panel 2, left panel 3, and right panel 4, thus improving safety.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
