[0047] Embodiment 1

[0048] Suitable for external convex bay windows

[0049] like Figures 1 to 10 As shown, the present application includes a protective frame and an outwardly protruding fixing frame. When applied to an outwardly protruding bay window, the protective frame and the outwardly protruding fixing frame need to be used in conjunction with each other.

[0050] The protective frame includes two columns 1, at least one coarse-adjustable telescopic cross bar 3 with adjustable length is arranged between the inner sides of the two columns 1, side supports 12 abutting against the wall are respectively arranged on the outer sides of the two columns 1, and the front sides of the two columns 1 are rotatably connected with protruding connecting rods 2; the protruding fixing frame 10 includes a mounting plate 5 and at least one group of fixing rod groups, the fixing rod groups include a first fixing rod 8 and a second fixing rod 6 respectively installed on both sides of the mounting plate 5, the first fixing rod 8 is inclined to open a first threaded hole in the horizontal direction, and the first threaded rod 9 is screwed into the first threaded hole, and the second fixing rod 6 is inclined to open a second threaded hole in the horizontal direction, and the second threaded rod 7 is screwed into the second threaded hole.

[0051] Before the construction workers start working on the convex bay window and before the bay window is installed, they first adjust the telescopic length of the coarse adjustment telescopic cross bar 3 to make it fit the width of the bay window so that the protective frame can be put into the bay window, then fine adjust the length of the side support 12 to make the side support 12 contact the wall, then rotate the convex connecting rod 2 to make the convex connecting rod 2 perpendicular to the column 1 at 90°, then adjust the first threaded rod 9 and the second threaded rod 7 to fix the convex fixing frame 10 to the indoor wall, and the convex fixing frame 10 plays a role of pressing and limiting the convex connecting rod 2 to prevent the protective frame from falling off or tipping over. Multiple coarse adjustment telescopic cross bars 3 form a guardrail to limit the workers from falling down, thereby achieving the purpose of protecting the safety of the construction workers working near the bay window.

[0052] It should be noted that the column 1 and the externally protruding connecting rod 2 are rotatably connected by a hinge. The hinge includes a core shaft, a first sleeve 42 and a second sleeve 43 rotatably connected to the two ends of the core shaft, and the first sleeve 42 is provided with a first hinge piece 41 for connecting the column 1; the second sleeve 43 is provided with a second hinge piece 44 for connecting the externally protruding connecting rod 2. Through holes are provided on the first hinge piece 41 and the second hinge piece 44, and the first hinge piece 41 and the second hinge piece 44 are respectively connected to the column 1 and the externally protruding connecting rod 2 by screws.

[0053] It should be noted that the first threaded hole and the second threaded hole are arranged obliquely, so that the first threaded rod 9 screwed into the first threaded hole and the second threaded rod 7 screwed into the second threaded hole form an acute angle, thereby preventing the external protruding fixing frame 10 from sliding down.

[0054] In this embodiment, the angle between the first threaded hole and the second threaded hole and the horizontal plane is 10° to 30°. In actual use, when the first fixing rod 8 slides downward when the force is released, the second fixing rod 6 is subjected to an upward reaction force, thereby ensuring that the outer protruding fixing frame 10 does not fall off.

[0055] In this embodiment, a first anti-skid pad is provided on the side of the first threaded rod 9 facing the second fixing rod 6, and a second anti-skid pad is provided on the side of the second threaded rod 7 facing the first fixing rod 8. Both the first anti-skid pad and the second anti-skid pad are rubber pads.

[0056] In this embodiment, the fine-adjustment telescopic cross rod 13 includes a second inner telescopic rod 131, a second outer telescopic rod 132, a rack 135 and a gear 134. The gear 134 is installed in the second inner telescopic rod 131 through a support plate 133. A screw block 136 exposed from the second inner telescopic rod 131 is fixedly installed in the middle of the gear 134. The gear 134 is meshed with the rack 135, and the end of the rack 135 is fixedly connected to the second outer telescopic rod 132.

[0057] When the screwing block 135 is rotated, the gear 134 rotates, the gear 134 drives the rack 135 to move, and the rack 135 drives the second outer telescopic rod 132 to extend into the second inner telescopic rod 131 or withdraw from the second inner telescopic rod 131, thereby achieving the purpose of fine-tuning the length of the telescopic cross bar 13.

[0058] By using a combination of the gear 134 and the rack 135, the minimum step length of telescopic movement is equal to the tooth pitch of the gear 134, and the adjustment effect is good, so that the side support 12 can be close to the wall.

[0059] In this embodiment, the outwardly protruding connecting rod 2 is a telescopic rod with adjustable length. At least one outwardly protruding connecting rod 2 is arranged on each column 1.

[0060] In this embodiment, a limiting piece 11 is provided at the end of the externally protruding connecting rod 2 , and the limiting piece 11 is used to abut against the mounting plate 5 when the externally protruding connecting rod 2 moves horizontally.

[0061] The externally protruding fixing frame 10 plays a role of pressing and limiting the externally protruding connecting rod 2 to prevent the protective frame from falling off or tipping over. A plurality of coarse adjustment telescopic cross bars 3 form a guardrail to limit the falling of workers, thereby achieving the purpose of protecting the safety of construction workers working near the bay window.

[0062] In this embodiment, the upright column 1, the outwardly protruding connecting rod 2, the coarse adjustment telescopic cross rod 3 and the outwardly protruding fixing frame 10 are all made of plastic.

[0063] In actual use, since the protective frame needs to be manually carried to the bay window by construction workers, making the protective frame out of plastic can reduce the labor of construction workers and avoid the chance of loss of metal products.

[0064] In actual use, there are multiple coarse adjustment telescopic cross bars 3, and the multiple coarse adjustment telescopic cross bars 3 are arranged in parallel. The intervals between the multiple coarse adjustment telescopic cross bars 3 are 10 to 20 cm.

[0065] During actual use, a reminder device is provided on the coarse adjustment telescopic cross bar 3. During actual use, the reminder device is a reflective strip attached to the coarse adjustment telescopic cross bar 3.

[0066] Embodiment 2

[0067] Suitable for recessed bay windows

[0068] like Figures 5 to 10As shown, the present application includes a protective frame and an outwardly protruding fixing frame. When applied to a recessed bay window, only the protective frame is used. Before the construction workers start working on the recessed bay window and before the bay window is installed, the protective frame is used as a side guardrail. First, adjust the telescopic length of the coarse-adjustment telescopic cross bar 3 to make it compatible with the width of the bay window so that the protective frame can be placed in the bay window, and then fine-adjust the length of the side support 12 so that the side support 12 abuts against the wall. Multiple coarse-adjustment telescopic cross bars 3 form a guardrail, which serves to limit the workers from falling below, thereby achieving the purpose of protecting the safety of construction workers working near the bay window.
