[0024] 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.

[0025] Please see Figures 1-8 This utility model provides a technical solution: an elevator fault protection device, including a housing 2. Two horizontal baffles 8 are arranged inside the housing 2. A hinge 4 is fixedly connected to one side of each horizontal baffle 8. A side baffle 9 is rotatably connected to each horizontal baffle 8 via the hinge 4. A lower support plate 14 is fixedly connected to the bottom of both the horizontal baffle 8 and the side baffle 9. The side of the lower support plate 14 is slidably connected to the bottom of the inner wall of the housing 2. A baffle 5 is fixedly connected to the side of the horizontal baffle 8 near the hinge 4. The top of the housing 2 has two side baffles... Insert plates 6 are inserted through and movable. The top of the horizontal baffle 8 and the side baffle 9 are provided with sliding grooves. The side of the insert plate 6 is movably inserted into the inner wall of the movable groove. The outer side of the horizontal baffle 8 is provided with a fixing groove. A hinge 7 is fixedly connected to one side of the box body 2. The box body 2 is rotatably connected to the insert rod 3 through the hinge 7. With the assistance of the insert rod 3 and the insert plate 6, the device completes the rigid construction of the structure, so that the device is more stable when in use. The end of the insert rod 3 away from the hinge 7 is movably inserted into the inner wall of the fixing groove.

[0026] Furthermore, the top of the horizontal baffle 8 and the side baffle 9 are respectively fixedly connected to the upper sliding plate 10 and the upper sliding plate 2 11 to improve the stability of the horizontal baffle 8 and the side baffle 9 when they move. The sides of the upper sliding plate 10 and the upper sliding plate 2 slidably connect to the top of the inner wall of the box 2.

[0027] Furthermore, limit blocks 13 are fixedly connected to both sides of the upper slide plate 10 to prevent the horizontal baffle 8 from completely sliding out of the box 2, thereby increasing the installation difficulty. The side of the limit block 13 is slidably connected to the inside of the top of the box 2.

[0028] Furthermore, both sides of the housing 2 are provided with insertion slots, which can be used to fix the horizontal baffle 8 and the side baffle 9 when they are not in use, thereby preventing the horizontal baffle 8 and the side baffle 9 from slipping out of the housing 2 during movement. The end of the insertion rod 3 away from the hinge 7 is movably inserted into the inner wall of the insertion slot.

[0029] Furthermore, both the inner surfaces of the horizontal baffle 8 and the side baffle 9 are fixedly connected with protrusions 15, and both the inner surfaces of the horizontal baffle 8 and the side baffle 9 are provided with mating grooves. This not only improves the stability of the horizontal baffle 8 and the side baffle 9 when they are stored, but also allows the device to be ventilated, thereby reducing the possibility of the device tipping over due to airflow in the elevator shaft or strong winds from the outside. The side of the protrusion 15 on the inner surface of the side baffle 9 is movably inserted into the mating groove on the inner surface of the horizontal baffle 8, and the side of the protrusion 15 on the inner surface of the horizontal baffle 8 is movably inserted into the mating groove on the inner surface of the side baffle 9.

[0030] Furthermore, an anti-slip pad 12 is fixedly connected to the side of the side baffle 9 away from the horizontal baffle 8, which can prevent the side baffle 9 from slipping, thus making the side baffle 9 more stable when placed.

[0031] Furthermore, the anti-slip pad 12 is trapezoidal to increase the contact area with the wall, thereby further improving the stability of the device when it is placed. A recycling trough is provided on one side of the horizontal baffle 8, and one end of the anti-slip pad 12 is movably inserted into the inner wall of the recycling trough.

[0032] Furthermore, a handle 1 is fixedly connected to the top of the housing 2 to facilitate the movement of the device.

[0033] Working principle: The device can be moved to the desired installation position using handle 1. Then, hinge 2 7 is rotated to open the insertion rod 3. At this time, the horizontal baffle 8 and the side baffle 9 are movable. The two sets of horizontal baffles 8 and side baffles 9 are pulled out from the sides of the housing 2 respectively. Then, hinge 1 4 is used to rotate the side baffle 9. When one side of the side baffle 9 is attached to the side of the baffle 5, the included angle between the horizontal baffle 8 and the side baffle 9 is 90 degrees. Then, the insertion plate 6 is pulled out from the top of the housing 2 and its two ends are inserted into the... The horizontal baffle 8 and the side baffle 9 are fixed in the sliding grooves at the top. Then, the horizontal baffle 8 is extended or retracted according to the width of the elevator. When it moves to the appropriate width, the plug rod 3 is rotated through the hinge 7 so that one end is inserted into the fixing groove on the outer side of the horizontal baffle 8, thereby fixing the horizontal baffle 8. At this time, both the horizontal baffle 8 and the side baffle 9 are immobile. Then, the anti-slip pad 12 on one side of the side baffle 9 is attached to the wall. The installation of the device is then completed.
