Description

Technical Field

[0001] This utility model belongs to the technical field of fall protection devices, and specifically relates to a stage fall protection device that is easy to install. Background Technology

[0002] As the core venue for artistic performances and large-scale events, the stage requires staff to move between platforms of varying heights. Actors may also approach dangerous edges due to large movements on the stage, obstructed views, or temporary adjustments to their positions. Without effective protection, accidents such as people slipping or equipment falling off can easily occur.

[0003] Most current mainstream protective devices adopt a modular assembly design, typically comprising dozens of independent components. During installation, workers must first verify the model numbers of each component, and then use hand tools to complete multiple steps such as bracket fixing, hook mounting, rope tensioning, and bolt locking. Furthermore, a large number of components require separate packaging during transportation and storage, and some smaller parts are easily lost during assembly and disassembly. Utility Model Content

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a stage fall protection device that is easy to install, including a frame 1. A protective net 2 is fixedly connected inside the frame 1. A bracket 3 is fixedly installed at the bottom of the frame 1. A movable component 4 is fixedly connected to the bottom of the bracket 3. A support component 5 is provided on the outer surface of the bracket 3. A connecting component 6 is provided between the support component 5 and the bracket 3. Limiting components 7 are provided on the outer surfaces of both the connecting component 6 and the support component 5. The movable component 4 is used to reduce the friction when the bracket 3 moves. The support component 5 and the connecting component 6 cooperate with each other to support and limit the bracket 3. The limiting component 7 is used to lock the support component 5 and the connecting component 6.

[0029] The support bracket 3 is moved by the moving component 4. After multiple sets of support brackets 3 are moved to the installation site, the support component 5 on the outer surface of the support bracket 3 is unfolded. The support component 5 pulls the connecting component 6 to rotate. When the support component 5 contacts the ground, the limiting component 7 locks the support component 5 and the connecting component 6. The support bracket 3 is fixed by the friction between the support component 5 and the ground to prevent unnecessary sliding of the support bracket 3. Then, the staff can climb onto the support bracket 3 to install the frame 1 and the protective net 2.

[0030] The support component 5 and the connecting component 6 of this utility model are both integrated on the outer surface of the bracket 3. The bracket 3 can be limited by unfolding the support component 5 and the connecting component 6. The limiting component 7 used to lock the support component 5 and the connecting component 6 is also integrated. It does not need to be separated during assembly, disassembly and transportation, which can avoid the loss of parts.

[0031] In one embodiment, the moving component 4 includes a base frame 401, which is fixedly connected to the bottom of the support 3. A screw 402 is threadedly connected to the inside of the base frame 401. A sliding rod 403 is rotatably connected to the lower end of the screw 402. A limit rod 404 is fixedly connected to the outer surface of the sliding rod 403. A pulley 405 is rotatably connected to the bottom of the sliding rod 403. There are multiple sets of pulleys 405.

[0032] Rotating screw 402 is threadedly connected to base frame 401. The rotation tendency of sliding rod 403 is blocked by limit rod 404. Screw 402 pushes sliding rod 403 to slide up and down inside base frame 401. When sliding rod 403 extends out of base frame 401, sliding rod 403 abuts against the ground through pulley 405, which can raise base frame 401. Conversely, when sliding rod 403 retracts into base frame 401, base frame 401 is lowered, which makes it easier to adjust the height of support 3 on top of base frame 401.

[0033] In one embodiment, the support component 5 includes a first hinge seat 501, which is fixedly mounted on the outer surface of the bracket 3. An inner rod 502 is fixedly connected to the outer surface of the first hinge seat 501, and an outer rod 503 is slidably connected to the outer surface of the inner rod 502. Limiting holes 504 are provided on the outer surfaces of the inner rod 502, the outer rod 503, and the bracket 3. There are multiple sets of limiting holes 504. A movable bolt 505 is threadedly connected to the outer surface of the outer rod 503. The movable bolt 505 passes through the outer rod 503 and extends into the interior of the inner rod 502. A second hinge seat 506 is fixedly connected to the end of the outer rod 503, and a square plate 507 is fixedly connected to the outer surface of the second hinge seat 506.

[0034] In one embodiment, the connecting component 6 includes a third hinge seat 601, which is fixed to the outside of the bracket 3. A connecting plate 602 is fixedly connected to the outer surface of the third hinge seat 601, and a fourth hinge seat 603 is fixedly connected to the outer surface of the connecting plate 602. The fourth hinge seat 603 is slidably connected to the outer rod 503.

[0035] Rotate the movable bolt 505 to separate it from the limiting hole 504 on the outer surface of the bracket 3, releasing the limiting fixation between the inner rod 502, the outer rod 503 and the bracket 3. At this time, the inner rod 502 and the outer rod 503 can be pushed to rotate through the first hinge seat 501, so that the inner rod 502 and the outer rod 503 are away from the bracket 3. At the same time, the outer rod 503 pulls the connecting plate 602 to rotate through the fourth hinge seat 603. Continue to rotate the movable bolt 505 to separate it from the inner rod 502, releasing the limiting fixation between the inner rod 502 and the outer rod 503. The outer rod 503 can be pulled to slide. Adjust the position of the second hinge seat 506 and the square plate 507 at the end of the outer rod 503. After the square plate 507 contacts the ground, put the movable bolt 505 back into the interior of the inner rod 502 to lock the inner rod 502 and the outer rod 503.

[0036] In one embodiment, the limiting component 7 includes a fixing bolt 701, which is fixedly connected to the pin of the second hinge seat 506. The end of the fixing bolt 701 is fixedly connected to a limiting plate 702, and the outer surface of the fixing bolt 701 is threadedly connected to a limiting nut 703.

[0037] In one embodiment, for the first hinge seat 501, the internal components of the first hinge seat 501, the second hinge seat 506, the third hinge seat 601, and the fourth hinge seat 603 are all fixedly connected to their pins, and the external components of the first hinge seat 501, the second hinge seat 506, the third hinge seat 601, and the fourth hinge seat 603 are all rotatably connected to their pins.

[0038] Rotating the limiting nut 703 causes it to move along the fixing bolt 701, moving it away from the external components of the second hinge seat 506 and releasing its limiting fixation. At this point, the second hinge seat 506 can drive the square plate 507 to rotate, facilitating contact between the square plate 507 and the ground. Then, rotating the limiting nut 703 back to press against the external components of the second hinge seat 506 allows for its limiting and locking. The fourth hinge seat 603 is equipped with the same fixing bolt 701, limiting plate 702, and limiting nut 703, operating on the same principle.

[0039] In one embodiment, for the bracket 3, a crossbar 8 is fixedly connected to the outer surface of the bracket 3, and there are multiple sets of crossbars 8.

[0040] The multiple sets of horizontal bars 8 can serve as leverage points for climbing supports 3. Workers can use the horizontal bars 8 to climb onto supports 3 to install the frame 1 and the protective net 2 without the need for additional climbing equipment, making installation convenient.

[0041] Through the above technical solutions, 1. The support component 5 and the connecting component 6 are both integrated on the outer surface of the bracket 3. The bracket 3 can be limited by unfolding the support component 5 and the connecting component 6. The limiting component 7 used to lock the support component 5 and the connecting component 6 is also integrated. It does not need to be separated during assembly, disassembly and transportation, which can avoid the loss of parts; 2. The bracket 3 is composed of multiple sets of horizontal bars 8 and vertical bars. The multiple sets of horizontal bars 8 are located between the vertical bars. The horizontal bars 8 are set to provide a foothold for climbing the bracket 3. Workers can climb to the top of the bracket 3 by stepping on the horizontal bars 8, which facilitates the assembly, disassembly and maintenance of the frame 1 and the protective net 2 at the top of the bracket 3 without the need for additional climbing equipment.
