[0002] In the installation of doors and windows in existing high-rise and super-high-rise buildings, safety accidents of falling from heights often occur. In order to ensure safety, some construction sites will first install guardrails and then install doors and windows. This construction method will bring inconvenience to the inner window frame when the construction is implemented. Because the gap between the protective pull rod and the doors and windows is too small, the space is not enough for the flexible adjustment of the glue gun for applying glass sealant, so the operation of the glue gun will be limited, and the line of sight will be limited during the adjustment of the glue gun, resulting in uneven glue application or missed glue application, which will cause quality defects in the installation of doors and windows and lead to safety hazards. If the guardrails are not installed first and the doors and windows are installed directly, the lack of protective devices during high-altitude operations will easily lead to safety accidents such as falling from heights. In addition, although the operators will use safety ropes when working at high altitudes, there is no suitable position or structure in the main building of the building under construction for the operators to hang the safety rope. Therefore, it is inconvenient for the operators to use safety ropes for protection. Utility Model Content

DETAILED DESCRIPTION

[0018] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0019] like Figure 1 , Figure 2 As shown, the anti-fall safety device for high-altitude operation of the present invention comprises a first support member 10 and a second support member 20. The first support member 10 and the second support member 20 can be inserted into each other and the connection length can be adjusted so that they can be tightly supported between the floor slabs. A locking assembly 30 is provided between the first support member 10 and the second support member 20, and the locking assembly 30 can lock the first support member 10 and the second support member 20 at the current connection length, and can be used to adjust the connection length of the first support member 10 and the second support member 20.

[0020] In order to facilitate hanging of a safety rope, a rope hanging portion 23 is provided on the second supporting member 20 .

[0021] In order to facilitate tightening between floor slabs and prevent loosening, the first supporting member 10 includes a first supporting plate 11 and a first supporting rod 12 , and the second supporting member 20 includes a second supporting plate 21 and a second supporting rod 22 .

[0022] The first support plate 11 is fixedly arranged at the end of the first support rod 12, and its area is relatively large, which can increase the friction force when in use, and prevent the first support member 10 and the second support member 20 from loosening. The shape of the first support plate 11 is not limited, and it is vertically fixed to the first support rod 12. The fixing method between the first support plate 11 and the first support rod 12 is not limited. In this embodiment, the first support plate 11 and the first support rod 12 are both made of steel material, the first support plate 11 is a steel plate, and the first support rod 12 is a steel pipe or a steel column, and the two are welded together.

[0023] The second support plate 21 is fixedly arranged at the end of the second support rod 22, and its area is relatively large, which can increase the friction force when in use, and prevent the first support member 10 and the second support member 20 from loosening. The shape of the second support plate 21 is not limited, and it is vertically fixed to the second support rod 22. The fixing method between the second support plate 21 and the second support rod 22 is not limited. In this embodiment, the second support plate 21 and the second support rod 22 are both made of steel material, the second support plate 21 is made of steel plate, and the second support rod 22 is made of steel pipe, and the two are welded together.

[0024] Furthermore, for the convenience of plugging, the second support rod 22 is in a tubular shape so as to be inserted into the first support rod 12. In a specific embodiment, the second support rod 22 can be made of a steel pipe.

[0025] The first support rod 12 can be a solid rod or a hollow tube, as long as its strength meets the requirements. Of course, for easy disassembly and transportation, the first support rod 12 is preferably a steel tube, whose outer diameter is smaller than the inner diameter of the second support rod 22, so that it can be inserted into the second support rod 22.

[0026] When in use, the first support member 10 is used to be tightly braced with the top floor, and the second support member 20 is used to be tightly braced with the bottom floor. In order to strengthen the stability of the structure, a plurality of reinforcing plates 24 may be arranged between the second support plate 21 and the second support rod 22. One end of the reinforcing plate 24 is fixedly connected to the second support plate 21, and the other end is fixedly connected to the second support rod 22. The reinforcing plate 24 may be a triangular steel plate, which is welded between the first support plate 11 and the first support rod 12.

[0027] Furthermore, in order to facilitate locking the connection and adjusting the connection length, a plurality of positioning holes 13 distributed along the axial direction thereof are provided on the first support rod 12. The positioning holes 13 penetrate the first support rod 12 in a direction perpendicular to the axial direction. Preferably, the positioning holes 13 penetrate the circumferential side wall of the first support rod 12 in a radial direction. The shape and size of the positioning holes 13 are not limited. In this embodiment, the positioning holes 13 are configured as circular holes. The distance between the positioning holes 13 can be set as required, and can be distributed at equal intervals or at non-equal intervals. By adjusting the positioning holes 13 at different height positions, the connection length can be quickly adjusted. However, the connection length is adjusted by the positioning holes 13 with low precision and is not suitable for fine-tuning.

[0028] The second support rod 22 is provided with an external thread section 221. The external thread section 221 refers to a section of the second support rod 22 provided with external threads, which is a part of the second support rod 22.

[0029] In this embodiment, the external thread segment 221 is disposed at the proximal end of the second support rod 22 opposite to the second support plate 21. In other embodiments, the external thread segment 221 may also be disposed at a non-end portion, for example, at the middle portion of the second support rod 22.

[0030] An adjustment hole 25 extending in the axial direction is provided on the external thread section 221. The adjustment hole 25 penetrates the second support rod 22 in a direction perpendicular to the axial direction. In other words, the adjustment hole 25 is a through hole penetrating in the radial direction. The shape of the adjustment hole 25 is not limited. In this embodiment, the adjustment hole 25 is a strip hole with a rectangular cross section.

[0031] Furthermore, the axially extending length of the adjustment hole 25 should be greater than the axial length of the positioning hole 13 (ie, the diameter of the positioning hole 13 ), so that the adjustment hole 25 can play an adjustment role.

[0032] Furthermore, the axially extending length of the adjustment hole 25 is smaller than the axially arranged length of the external thread section 221 , so that it is convenient to adjust the locking assembly 30 to adjust the connection length.

[0033] The locking assembly 30 can be connected to the external thread section 221 and inserted between the positioning hole 13 and the adjustment hole 25 to lock the first supporting member 10 and the second supporting member 20 at a current connection length.

[0034] Furthermore, the locking assembly 30 includes a latch pin 31 and a locking ring 32 .

[0035] The latch 31 is used to be inserted into the corresponding adjustment hole 25 and the positioning hole 13. The shape of the latch 31 is not limited, as long as it can pass through the adjustment hole 25 and the positioning hole 13. In this embodiment, in order to prevent the latch 31 from easily falling out of the adjustment hole 25 and the positioning hole 13, the latch 31 is arranged in a ring shape, and a notch 311 is provided on it to present a broken ring shape. When in use, the latch 31 can be inserted into the adjustment hole 25 and the positioning hole 13 from the notch 311, so that the first support rod 12 and the second support rod 22 are connected together.

[0036] The locking ring 32 is threadedly connected to the external thread section 221 and can axially limit the latch 31. Since the distance between the positioning holes 13 is large, the adjustable length range is large, but the adjustable accuracy is low. Adjusting the length through positioning holes 13 at different heights does not necessarily make the length of the first support member 10 and the second support member 20 match the distance between the floor slabs, so that the first support member 10 and the second support member 20 cannot be tightly supported between the floor slabs. The locking ring 32 is threadedly connected to the external thread section 221, and it can move axially relative to the external thread section 221 to fine-tune its height, thereby fine-tuning the height of the latch 31, and then fine-tuning the connection length of the first support member 10 and the second support member 20.

[0037] The locking ring 32 is annular and has an internal thread, which can not only be used for fine-tuning but also enhance the reliability of the connection between the first support rod 12 and the second support rod 22 .

[0038] When the first support member 10 and the second support member 20 are inserted together, the plug 31 is inserted into the adjustment hole 25 and the positioning hole 13 at a certain height, and the connection length of the first support member 10 and the second support member 20 can be roughly adjusted. At this time, the plug 31 still has a certain degree of freedom and can move within the range of the adjustment hole 25. At this time, by adjusting the locking ring 32, the height of the plug 31 in the axial direction can be adjusted, thereby achieving fine adjustment of the connection length.

[0039] In order to facilitate the hanging of the safety rope, a rope hanging part 23 is provided on the second support rod 22. The rope hanging part 23 is ring-shaped, and a hole is formed between the rope hanging part 23 and the second support rod 22 for the safety rope to pass through.

[0040] The location of the hanging rope portion 23 is not limited. In this embodiment, the hanging rope portion 23 is disposed between the external thread segment 221 and the second support plate 21 .

[0041] The hanging rope portion 23 is fixedly connected to the second support rod 22 . Preferably, the hanging rope portion 23 is made of steel and is welded to the second support rod 22 .

[0042] The number of the hanging rope parts 23 is not limited. In this embodiment, two hanging rope parts 23 are provided on the second support rod 22 .

[0043] When in use, the first support rod 12 is inserted into the second support rod 22, so that the first support plate 11 is supported on the ground, and the second support plate 21 is in contact with the top floor, and then the latch 31 is inserted into the adjustment hole 25 and the positioning hole 13 of the corresponding height to connect the first support member 10 and the second support member 20. Then adjust the locking ring 32 so that the latch 31 is adjusted to a suitable position, thereby fine-tuning the connection length of the first support member 10 and the second support member 20, so that the first support member 10 and the second support member 20 are tightly supported between the floor and cannot be loosened. Then, the operator can hang the safety rope on the hanging rope part 23. During operation, the safety rope is tied to the operator, so that even if he accidentally falls out of the window, he can be pulled by the safety rope to avoid falling, thereby protecting the safety of the operator.

[0044] During disassembly, the first supporting member 10 and the second supporting member 20 only need to be adjusted to prevent them from being tightened, so that they can be taken out and carried to other working floors.

[0045] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
