[0002] During building construction, the protection of openings is crucial, such as elevator shafts, skylights, electrical wiring shafts, ventilation shafts, and chimney openings, to effectively ensure the safety of construction workers. In situations where frequent adjustments to the size or type of opening are required, retractable opening protection devices are essential.

[0003] Patent CN219826263U discloses a retractable opening protection device. It uses a first telescopic rod to extend and retract a first protective frame laterally, and a second telescopic rod to extend and retract a second protective frame laterally, making the device suitable for openings of different widths. A vertical sliding component allows for the vertical sliding of the first and second protective frames, and a fixing device secures the first and second protective frames respectively, making the device suitable for openings of different heights. However, this opening protection device relies on telescopic rods within its frame to adjust height and width, limiting its adjustment range and preventing the combination of more protective frames to protect higher or wider openings. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a multi-purpose retractable building construction opening protection facility.

[0005] A multi-purpose retractable building construction opening protection facility, comprising adjacent frames connected by an adjustable structure;

[0006] Two opposite sides of the frame are detachably connected to the sidewall of the opening via clips; the side of the frame can be selectively connected to another frame.

[0007] The adjustable structure is used to adjust the distance between adjacent frames.

[0008] Furthermore, the frame includes a left frame and a right frame, and several crossbeams are arranged between the left frame and the right frame, with columns arranged between adjacent crossbeams.

[0009] Furthermore, the topmost and bottommost crossbeams are respectively provided with upper through holes and lower through holes; the left frame is provided with a left through hole, and the right frame is provided with a right through hole.

[0010] Furthermore, the frame can also be detachably connected to a protective net.

[0011] Furthermore, the adjustable structure includes a snap-fit ​​sleeve fixed to a crossbeam of one of the frames and a hook connected to a crossbeam of another frame; the hook is attached to the snap-fit ​​sleeve of the crossbeam at different positions to form an overall protective frame of different heights.

[0012] Furthermore, the hook is fixedly or detachably connected to a crossbeam of another of the frames.

[0013] Furthermore, the adjustable structure includes a first sleeve and an adjusting rod threaded to both ends of the first sleeve;

[0014] The outer wall of the adjusting rod is threaded, and the threads of the two adjusting rods located at both ends of the first sleeve are in opposite directions;

[0015] The other end of the adjusting rod is also fixedly connected to a positioning clip, which is used to fix it to the uppermost or lowermost crossbeam.

[0016] Furthermore, the uppermost and lowermost crossbeams are also provided with threaded holes, which are threadedly connected to the adjustable structure;

[0017] The adjustable structure includes an upper rod, a second sleeve, and a lower rod that are fixedly connected in sequence; the upper rod and the lower rod are respectively provided with threads in opposite directions; the upper rod is threaded to the lowest crossbeam of the upper frame, and the lower rod is threaded to the highest crossbeam of the lower frame.

[0018] Furthermore, the clip is detachably connected to the left and right side frames of the frame, or detachably connected to the two crossbeams located at the edge of the frame;

[0019] The fastener includes a snap-fit ​​part for connecting to the left frame, right frame, or crossbeam, and a positioning part for connecting to the side wall of the opening.

[0020] Furthermore, the snap-fit ​​portion has a first positioning hole, and the positioning portion has a second positioning hole.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The detachable connections and adjustable structures between the frames of this multi-purpose retractable construction opening protection facility allow for combinations of protective measures to meet specific needs, achieving higher or wider opening protection and overcoming the limitation of adjustment range in existing technologies. Through the design of various adjustable structures, flexible adjustments to height and width can be made to adapt to the protection requirements of openings of different sizes and types.

[0023] Furthermore, this multi-purpose retractable construction opening protection facility consists of multiple frames, each including a left frame, a right frame, several crossbeams, and several columns. The sides of the frames are detachably connected to the sidewalls or inner walls of the opening via clips. The frames can be interlocked using an adjustable structure to form an adjustable protection facility to meet the size requirements of different construction openings. The distance between the frames is adjusted using the adjustable structure. Specifically, a snap-fit ​​sleeve is fixed to the crossbeam of one frame, while a hook is connected to the crossbeam of another frame. The hooks can be attached to the snap-fit ​​sleeves at different positions, thereby adjusting the height between the frames to form an overall protective frame of different heights.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0047] Example 1:

[0048] like Figures 1-6 As shown, this embodiment provides a multi-purpose retractable construction opening protection facility, including adjacent frames connected by an adjustable structure. Two opposite sides of frame 1 are detachably connected to the sidewall or inner wall of the opening via clips 2. The side of frame 1 can be selectively connected to another frame 1. Two frames 1 can be used to form an adjustable and retractable construction opening protection facility, or more than two frames 1 can be used to form an adjustable and retractable construction opening protection facility. The adjustable structure is used to adjust the distance between adjacent frames 1, thereby achieving the retractability of the construction opening protection facility.

[0049] Specifically, frame 1 includes a left frame 11 and a right frame 12. Several crossbeams 13 are arranged between the left frame 11 and the right frame 12, and columns 14 are arranged between adjacent crossbeams. The uppermost crossbeam 13, the lowermost crossbeam 13, and the left and right frames 11 together constitute the frame's border. The uppermost and lowermost crossbeams 13 have upper through holes 131 and lower through holes 132, respectively. The left frame 11 has a left through hole 111, and the right frame 12 has a right through hole 121, facilitating connection with other frames or fasteners 2. Furthermore, the left frame 11 has multiple sets of left through holes 111, each set including through holes on all four sides, with the through holes on opposite sides being flush for easy connection. Similarly, the right frame 12 is provided with multiple sets of right through holes 121, each set of right through holes 1211 including through holes located on the four sides, wherein the through holes on opposite sides are flush to facilitate connection. The top and bottom crossbeams 13 are designed in the same way, with corresponding through holes provided on the four sides.

[0050] The left frame 11, right frame 12, crossbeam 13, and column 14 are all made of square tubing. A protective net can also be detachably connected to the frame; bolts can be used to achieve this detachable connection, further enhancing the protective effect.

[0051] In this embodiment, the adjustable structure includes a snap-fit ​​sleeve 3 fixed to a crossbeam 13 of one frame 1 and a hook 4 connected to a crossbeam 13 of the other frame 1. The hook 4 is attached to the snap-fit ​​sleeves 13 of crossbeams at different positions to form an overall protective frame of different heights. More specifically, the hook 4 is fixed to the uppermost crossbeam 13 of the other frame 1. The snap-fit ​​sleeve 3 is a round tube, and the hook 4 is a hook-shaped component formed by bending steel bars.

[0052] In this embodiment, the frame 1 is connected to the inner wall or side wall of the opening via a clip 2. The clip 2 is detachably connected to the left frame 11 and the right frame 12 of the frame 1, or detachably connected to the two crossbeams 13 located at the edge of the frame 1. The clip 2 includes a snap-fit ​​part 21 for connecting to the left frame 11, the right frame 12 or the crossbeams 13 and a positioning part 22 for connecting to the side wall of the opening.

[0053] Among them, the snap-fit ​​part 21 of the card 2 adopts a U-shaped groove, such as Figure 3 As shown, the groove is adapted to the outer contour of the left frame 11, the right frame 12, or the crossbeam 13; the center of the snap-fit ​​part 21 is provided with a first positioning hole 211, which is adapted to the through hole provided in the left frame 11, the right frame 12, or the crossbeam 13, so as to facilitate the snap-fit ​​part to be bolted to the corresponding frame or the crossbeam 13 located at the edge; the ends of the two legs of the snap-fit ​​part are respectively connected to a flat positioning part 22, which is provided with a second positioning hole 221. By using fasteners such as bolts, expansion bolts, or positioning pins to pass through the second positioning hole, the snap-fit ​​part 2 can be fixed to the inner wall or side wall of the opening.

[0054] Another type of card, such as... Figures 4-6 As shown, its locking part 21 still adopts a U-shaped groove, and its two legs are provided with first positioning holes 211. The positioning part 22 is fixed to the outer end of the horizontal plate and is located on the top of one of the legs. The locking part 2 of this structural design can prevent the entire edge of the frame from contacting the side wall or inner wall of the construction opening when fixing the frame to the construction opening, thereby avoiding damage to the side wall or inner wall of the opening during construction.

[0055] The snap-fit ​​portion 21 and the positioning portion 22 of the clip 2 can also be equipped with anti-slip pads or made of more robust materials to improve the stability and reliability of the connection.

[0056] The multi-purpose retractable construction opening protection facility provided in this embodiment consists of multiple frames 1. Each frame 1 includes a left frame 11, a right frame 12, several crossbeams 13, and several columns 14. The sides of the frames 4 are detachably connected to the side wall or inner wall of the opening via fasteners 2. The frames 1 can be spliced ​​together with an adjustable structure to form an adjustable protection facility to meet the size requirements of different construction openings.

[0057] The distance between the frames 1 is adjusted via an adjustable structure. Specifically, a snap-fit ​​sleeve 3 is fixed to the crossbeam 13 of one frame 1, while a hook 4 is connected to the crossbeam 13 of the other frame 1. The hook can be attached to the snap-fit ​​sleeve at different positions, thereby adjusting the height between the frames to form an overall protective frame of different heights. This design allows the protective facility to flexibly adapt to construction openings of different heights.

[0058] Clip 2 is used to fix frame 1 to the side wall or inner wall of the construction opening. The snap-fit ​​part 21 of clip 2 adopts a U-shaped groove, which is adapted to the outer contour of the frame 1's edge or crossbeam, and is connected to frame 1 by bolts passing through the first positioning hole 211 of snap-fit ​​part 21. To further enhance the protective effect, the protective net can be detachably connected to the frame by bolts, which not only improves the safety of the protective facility but also facilitates quick installation or removal of the protective net when needed.

[0059] The multi-purpose retractable construction opening protection facility provided in this embodiment allows for quick adjustment of the height between frames 1 through the cooperation of hook 4 and snap-fit ​​sleeve 3, adapting to openings of different heights. Compared with the existing technology that adjusts height via telescopic rods, this method offers a wider adjustment range and is easier to operate. The detachable design of the clip 2 enables quick installation and disassembly of the protection facility, facilitating use when frequently adjusting the size or type of opening.

[0060] Example 2:

[0061] The multi-purpose retractable building construction opening protection facility provided in this embodiment differs from that in Embodiment 1 in that the hook 4 can be detachably connected to the crossbeam 13 of another frame 1.

[0062] Specifically, such as Figure 7As shown, threaded connection holes are also provided on the crossbeam 13 of another frame 1. The straight sections of the hooks 4 are threaded, and each hook is threaded to the corresponding threaded connection hole on one of the crossbeams 13, and tightened with a nut 41, thus forming an adjustable hook 4. When the construction opening is small, each hook 4 can be installed on the lower crossbeam 13 of the frame 1; when the construction opening is large, each hook 4 can be installed on the upper crossbeam of the frame. The detachable installation design of the hooks 4 facilitates adjustment according to actual needs, and allows for reasonable arrangement of the installation position of each hook according to the size of the construction opening, enhancing the applicability of this protective facility.

[0063] Example 3:

[0064] The multi-purpose retractable building construction opening protection facility provided in this embodiment differs from that in Embodiment 1 in that its adjustable structure is different. In this embodiment, as... Figures 8-11 As shown, the adjustable structure includes a first sleeve 5 and adjusting rods 6 threadedly connected to both ends of the first sleeve 5; wherein, the outer wall of the adjusting rods 6 is threaded, and the two adjusting rods 6 located at both ends of the first sleeve 5 have opposite thread directions. A positioning clip 7 is also fixedly connected to the other end of the adjusting rod 6 for fixed connection to the uppermost or lowermost crossbeam 13. The positioning clip 7 is a slot-shaped structure with one end open, and the positioning clip 7 has a third positioning hole 71 for connection.

[0065] In this embodiment, rotating the first sleeve 5 allows both adjusting rods 6 to simultaneously rotate inward or outward within the first sleeve 5, thereby adjusting the distance between the two frames and forming an overall height-adjustable construction opening protection facility. Alternatively, three or more frames 1 can be used, with two adjacent frames employing the adjustable structure described in this embodiment to form an overall structure with adjustable spacing, thus adapting to construction openings of different heights.

[0066] When applied to construction openings, if the width of the protective facility needs to be adjusted, the entire device can be rotated 90° for use. Since the left frame 11 and right frame 12 located on the outer side of the frame 1 have corresponding through holes on their four sides, when fixed to the inner wall or side wall of the construction opening, placing it in its original position or rotating it 90° facilitates the connection and installation of the clips 2.

[0067] Example 4:

[0068] The multi-purpose retractable building construction opening protection facility provided in this embodiment differs from that in Embodiment 1 in that its adjustable structure is different. In this embodiment, as... Figures 12-13As shown, the uppermost and lowermost crossbeams 13 are also provided with threaded holes 133, which are threaded to the adjustable structure. The adjustable structure includes an upper rod 8, a second sleeve 9, and a lower rod 10, which are sequentially fixed together. The upper rod 8 and the lower rod 10 are respectively provided with threads in opposite directions. The upper rod 8 is threaded to the lowermost crossbeam 13 of the upper frame 1, and the lower rod 10 is threaded to the uppermost crossbeam 13 of the lower frame 1.

[0069] Through the adjustable structure in this embodiment, rotating the second sleeve 9 can move two adjacent frames closer together or further apart, thereby enabling the overall structure of the construction opening protection device to be adjustable. When the construction opening is large, more frames can be used, and the adjustable structure in this embodiment can be used to connect adjacent frames to assemble a suitable protection device.

[0070] In the above examples, the design of various adjustable structures enables flexible adjustment of height and width to adapt to the protection needs of openings of different sizes and types.

[0071] The detachable connection and adjustable structure between the frames 1 allow the protective facilities to be combined according to actual needs, achieving higher or wider opening protection, thus solving the problem of limited adjustment range in the prior art.

[0072] The detachable design and adjustable structure of the clip 2 enable the protective facilities to be installed and dismantled quickly, improving construction efficiency.

[0073] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
