[0029] In order to solve the problem of frequent disassembly and assembly increasing the safety hazard of workers, the present invention provides a protective device for edge openings. The following is a further description of the protective device for edge openings using specific embodiments in conjunction with the accompanying drawings.

[0030] See Figures 1 to 8 As shown, a protective device for an edge opening includes:

[0031] The bracket is used to be fixed in the elevator shaft. The bracket includes a plurality of vertical poles 1. The plurality of poles 1 are arranged along the edge of the elevator shaft, and the height of the poles 1 is adapted to the depth of the elevator shaft.

[0032] Multiple first protection plate groups, respectively arranged between each two adjacent floors, each first protection plate group includes multiple first protection plates, and the multiple first protection plates are vertically arranged and respectively fixed between each two adjacent vertical poles 1 to form vertical protection for the elevator shaft; and

[0033] There are multiple second protective plate groups, the number of which is the same as that of the first protective plate group, each second protective plate group includes multiple second protective plates, and the multiple second protective plates are arranged around the outside of the bracket, and the multiple second protective plates are horizontally arranged and fixed on the first protective plate group, for covering the gap between the first protective plate group and the floor edge 4, so as to form horizontal protection for the elevator shaft.

[0034] Specifically, in this embodiment, there are four vertical poles 1, and the four vertical poles 1 are respectively fixed at the four corners of the elevator shaft, so that the first protective plate fixed between two adjacent vertical poles 1 respectively blocks the four sides of the elevator shaft, thereby protecting the elevator shaft opening in the vertical direction;

[0035] By adopting the above design, the elevator shaft opening can be protected vertically by the enclosed first protective plate, and the gap between the vertical pole 1, the first protective plate and the floor edge 4 can be blocked by the horizontally arranged second protective plate, thereby achieving horizontal protection. After the entire protective device is installed to form protection, it will not hinder the secondary construction of the floor, and it does not need to be frequently disassembled and assembled. The overall installation is simple and reusable, with high economic benefits.

[0036] Among them, see Figure 1 and 3 As shown, the first protective plate is formed by splicing a plurality of first plates 2, and each two adjacent first plates 2 are spliced and connected by a first connecting member 5;

[0037] The plurality of first plates 2 in each first protective plate are arranged in an array, and each first plate 2 is provided with a plurality of first punching holes 8 in an array. Each two adjacent first plates 2 are overlapped with each other in the width direction and / or in the height direction, and at least one first connecting member 5 is used to selectively connect at least one pair of first punching holes 8 located in the overlapped area and facing each other, so as to achieve splicing of the two adjacent first plates 2 in the width direction or in the height direction.

[0038] The first punching hole 8 is a waist-shaped hole extending along the width direction / height direction.

[0039] For details, see Figure 1 and 3 As shown, the first punching holes 8 on the first plate 2 are formed in multiple columns, and the multiple columns of first punching holes 8 are arranged equidistantly along the width direction of the first plate 2, and each column of first punching holes 8 includes multiple first punching holes 8 arranged equidistantly along the height direction of the first plate 2;

[0040] By laying out two adjacent first plates 2 along the width direction, one of the rows of first punching holes 8 on one of the first plates 2 is selectively aligned with the other row of first punching holes 8 on the other first plate 2, and then at least one first connecting member 5 is used to selectively connect at least one pair of first punching holes 8 located in the laying area and facing each other, so as to realize the horizontal splicing of the two adjacent first plates 2.

[0041] By adopting the above design, two adjacent first plates 2 can be spliced in the transverse direction, and the transverse length of the formed first protective plate can be controlled and adjusted, which is convenient for adjustment and use.

[0042] Further, the plurality of first punching holes 8 in the plurality of first punching hole 8 columns are arranged along the width direction of the first plate 2 to form a plurality of first punching hole 8 rows;

[0043] By arranging two adjacent first plates 2 in the height direction, the rows of first punching holes 8 on one of the first plates 2 are selectively aligned with the rows of first punching holes 8 on the other first plate 2, and then at least one first connecting member 5 is used to selectively connect at least one pair of first punching holes 8 located in the arrangement area and facing each other, so as to realize vertical splicing of the two adjacent first plates 2.

[0044] By adopting the above design, two adjacent first plates 2 can be spliced vertically, and the vertical length of the formed first protective plate can be controlled and adjusted, and the horizontal and vertical lengths of the formed first protective plate can be adjusted.

[0045] As shown in the figure, the first connecting member 5 includes a connecting shaft 501, a first clamping plate 502 and a second clamping plate 503 arranged perpendicular to the connecting shaft 501 and parallel to each other. The first clamping plate 502 is fixed to one end of the connecting shaft 501, and the second clamping plate 503 is movably connected to the connecting shaft 501 relative to the first clamping plate 502. The first connecting member 5 also includes a driving member connected to the other end of the connecting shaft 501 and used to drive the second clamping plate 503 to move relative to the first clamping plate 502. The first clamping plate 502 is adapted to the size of the first punching hole 8.

[0046] By aligning the first clamping plate 502 and passing it through the pair of first punching holes 8 that are positioned opposite each other, and rotating the connecting shaft 501 so that the first clamping plate 502 and the second clamping plate 503 intersect with the long sides of the first punching holes 8, when the second clamping plate 503 is driven close to the first clamping plate 502, the second clamping plate 503 and the first clamping plate 502 can respectively abut against the plate surfaces of the two adjacent first plates 2, thereby achieving splicing and fixing of the two adjacent first plates 2;

[0047] The driving member includes a rotating cylinder 504 and a first screw 506. The first end of the rotating cylinder 504 is rotatably connected to the other end of the connecting shaft 501. One end of the first screw 506 is fixed to the second clamping plate 503, and the other end is screwed to the rotating cylinder 504. By rotating the rotating cylinder 504, the first screw 506 can be driven to move the second clamping plate 503 relative to the first clamping plate 502.

[0048] Specifically, in this embodiment, a nut 505 is fixedly connected to one end of the rotating cylinder 504 facing the first screw 506 , and the rotating cylinder 504 is screwed to the first screw 506 through the nut 505 ;

[0049] By adopting the above design, when in use, the rotating cylinder 504 can be rotated to drive the nut 505 to rotate, and the first screw rod 506 can be driven by the thread to pull the second clamping plate 503 away from the first clamping plate 502, so that a gap is formed between the first clamping plate 502 and the second clamping plate 503, and then the opposite sides of the two adjacent first plates 2 are stacked and the first punching holes 8 on the two first plates 2 are aligned in columns or rows, so that the first punching holes 8 in the stacking areas of the two adjacent first plates 2 are aligned, and the first clamping plate 502 can be passed through the opposite side. The two first punching holes 8 are aligned, and then the connecting shaft 501 is deflected to drive the first clamping plate 502 and the second clamping plate 503 to rotate 90 degrees, and then the rotating cylinder 504 is rotated in the opposite direction. The first screw 506 can be used to push the second clamping plate 503 and the first clamping plate 502 closer to each other, so that the second clamping plate 503 and the first clamping plate 502 are respectively pressed against the two sides of the stacking area of the adjacent two first plates 2, thereby fixing the adjacent two first plates 2 to achieve splicing, and the adjacent two first plates 2 can be spliced through multiple first connecting members 5.

[0050] Furthermore, a slideway is provided on the connecting shaft 501, and the second splint 503 is slidably connected to the slideway to achieve relative movement with the connecting shaft 501. The second splint 503 is fixedly connected to a U-shaped block 507 on the side facing the first splint 502, and a spring 508 fixed to the first splint 502 is fixedly connected in the U-shaped groove of the U-shaped block 507. The first splint 502 and the second splint 503 are fixed with rubber pads 509 on the sides that are opposite to each other. The spring 508 with elastic force can always give the U-shaped block 507 a supporting force, which is transmitted to the first screw 506, which can make the adjustment have texture and prevent the rotating cylinder 504 from being easily rotated by force; by providing the rubber pad 509, the first splint 502 and the second splint 503 can be prevented from hard contact with the first plate 2, thereby avoiding indentations.

The first semicircular ring 606 is fixed to the other end of the connecting plate 602. The second semicircular ring 607 can be connected to the first semicircular ring 606 in an openable and closable manner. The first semicircular ring 606 and the second semicircular ring 607 are closed and are used to be sleeved on the vertical pole 1. The second connecting member 601 also includes a locking member for locking the closed first semicircular ring 606 and second semicircular ring 607.

[0053] Specifically, a second punched hole 603 is formed at one end of the connecting plate 602 away from the first semicircular ring 606. The second connecting member 601 has the same structure as the first connecting member 5. When in use, the connecting plate 602 can be fixed to the first protective plate by aligning the second punched hole 603 with the first punched hole 8 on the first plate 2 and then fixing them with the second connecting member 601.

[0054] Furthermore, the locking member includes a posting plate 608, a horizontal plate 609, a vertical plate 610, a second screw 611, a through-hole 604 and a baffle 605. The posting plate 608 is fixed on the second semicircular ring 607. When the second semicircular ring 607 and the first semicircular ring 606 are closed, the posting plate 608 is in contact with the connecting plate 602. The horizontal plate 609 is vertically fixed to the side of the posting plate 608 facing the connecting plate 602. The vertical plate 610 is vertically fixed to the horizontal plate 609. The second screw 611 is screwed and connected to the vertical plate 610. The through-hole 604 is opened on one side of the connecting plate 602 near the first semicircular ring 606. At the end, the baffle 605 is rotatably connected to the connecting plate 602. In the process of closing the first semicircular ring 606 and the second semicircular ring 607, the horizontal plate 609, the vertical plate 610 and the second screw 611 will pass through the through opening 604. When the sticking plate 608 is attached to the connecting plate 602, the baffle 605 can be rotated to block between the vertical plate 610 and the connecting plate 602, and then the second screw 611 is turned to rotate and push against the baffle 605, so as to achieve locking of the first semicircular ring 606 and the second semicircular ring 607. When disassembly is required, the reverse operation can be performed. The disassembly and assembly are convenient and flexible and can be used repeatedly.

The outer portion of the end is provided with a thread, and the slider 706 is screwed into the outer portion of the rotating rod 709 through the thread. By rotating the twisting rod 710, the worm gear 711 is rotated, thereby driving the worm 712 to rotate, which will drive the rotating rod 709 to rotate. The thread can drive the slider 706 to move along the slide rail 707, thereby pushing the support rod 705 or pulling the support rod 705, so as to adjust the angle between the third plate 702 and the fourth plate 703, so that even if the first protective plate is not in a vertical state, the second protective plate can be adjusted to be horizontally set, which can well cover the gap; a third screw (not shown) is screwed into the box body 708, and after the third plate 702 and the fourth plate 703 are adjusted, the third screw can be rotated to extend into the box body 708 and press against the outer portion of the worm 712, which can limit the easy rotation of the worm 712 to achieve locking of the worm 712 and prevent the twisting rod 710 from being easily rotated by external force, thereby affecting the use effect.
