Technical Field

[0001] The utility model relates to safety equipment for working at heights, and particularly to a device for preventing falling during the decoration of high-rise building windows. Background Art

[0002] In China, the peak of the renovation of old communities has arrived. When high-rise houses are sold and renovated again, it is difficult for a single household to take exterior wall scaffolding protection measures. During the renovation of doors and windows, "high-altitude falling objects" are likely to occur.

[0003] Currently, the mainstream decoration protection measures for house decoration are to use screens or nets to fix. The protection effect of these protection measures is not good, they are easy to break, and there are risks during the installation process. Some even do not take protection measures directly and only set warning lines below. The existing patents for window protection devices mainly focus on the protection of workers during building construction and daily life protection, and are not applicable to the window decoration scenario.

[0004] The existing devices cannot solve the problem of debris falling during the disassembly of window frames during the decoration of house windows, and can only be used for daily protection or the protection of workers during building construction.

[0005] Therefore, a device for preventing falling during the decoration of high-rise building windows is needed. Summary of the Utility Model

A cloth surface is installed on the framework.

[0008] Furthermore, the pipe fitting is detachably connected to the support base, and the framework is detachably connected to the seat shell of the electric push rod and the telescopic rod.

[0009] Furthermore, the framework includes a first pipe fitting detachably connected to the front part of the seat shell of the electric push rod. A first fixing ring is installed at the front end of the first pipe fitting. A plurality of connecting rods are hinged at intervals along the circumferential direction of the first fixing ring. A second pipe fitting is detachably connected to the front part of the telescopic rod. A second fixing ring is fixed at the front end of the second pipe fitting. A plurality of support rods are hinged at intervals along the circumferential direction corresponding to the second fixing ring. The other end of the connecting rod is hinged to the support rod.

[0010] Furthermore, the first pipe fitting is placed on the front of the seat shell of the electric push rod and locked by bolts, the second pipe fitting is placed on the front of the telescopic rod and locked by bolts, and the outer diameter of the second pipe fitting is greater than the inner diameter of the first fixing ring.

[0011] Furthermore, at least four support rods are hinged on the second fixing ring and cooperate to form an "X" shape when unfolded, and pressure sensors are installed at the ends of the support rods.

[0012] Furthermore, eight support rods are hinged on the second fixing ring and form a "M" shape after being unfolded, and pressure sensors are installed at the ends of the support rods located diagonally upward.

Detailed implementation mode

[0025] To make the above features and advantages of the present utility model more understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings, but the present utility model is not limited thereto.

[0026] Reference Figures 1 to 4

[0027] A device for preventing the fall of high-rise building window decoration includes a support base 10. A telescopic rod 30 driven by an electric push rod 20 is horizontally installed at the upper end of the support base. A skeleton 40 that unfolds when the telescopic rod contracts is installed between the front end of the seat shell of the electric push rod and the telescopic rod. A cloth surface is installed on the skeleton.

[0028] In this embodiment, the pipe fitting is detachably connected to the support base, and the skeleton is detachably connected to the seat shell of the electric push rod and the telescopic rod, which facilitates the disassembly and assembly between components, reduces the space occupied during storage, and is convenient for handling.

[0029] In this embodiment, the skeleton includes a first pipe fitting 41 detachably connected to the front part of the seat shell of the electric push rod. A first fixing ring 42 is installed at the front end of the first pipe fitting. A plurality of connecting rods 43 are hinged at intervals along the circumferential direction of the first fixing ring. A second pipe fitting 44 is detachably connected to the front part of the telescopic rod. A second fixing ring 45 is fixed at the front end of the second pipe fitting. A plurality of support rods 46 are correspondingly hinged at intervals along the circumferential direction of the second fixing ring. The other end of the connecting rod is hinged to the support rod. The cloth surface is rectangular, and each support rod is sewn or anchored to the cloth surface.

[0030] In this embodiment, the first pipe fitting is sleeved on the front part of the seat shell of the electric push rod and locked by bolts. The second pipe fitting is sleeved on the front part of the telescopic rod and locked by bolts, so as to facilitate the disassembly and assembly between the skeleton and the electric push rod and the telescopic rod. The outer diameter of the second pipe fitting is larger than the inner diameter of the first fixing ring to limit the contraction of the telescopic rod.

[0031] In this embodiment, at least four support rods that form an "×" shape after being unfolded are hinged on the second fixed ring, and pressure sensors 47 are installed at the ends of the support rods. Specifically, eight support rods that form a "rice" shape after being unfolded can be hinged on the second fixed ring, and eight connecting rods are correspondingly hinged on the first fixed ring. Pressure sensors are installed at the ends of the support rods that are diagonally upward. The pressure sensors are electrically connected to the electric telescopic rods through a single-chip microcomputer, so as to detect the pressure when the support rods are unfolded and contact the window edge through the pressure sensors.

[0032] In this embodiment, the connecting rods are of equal length, and hinge members 48 fixedly connected to the support rods are hinged at the other ends of the connecting rods. The fixed positions of the hinge members on each support rod and the distance between the hinge points where the support rods are hinged to the second fixed ring are equal or close, so as to better control the synchronous unfolding of the support rods.

[0033] In this embodiment, the support base includes a floor base 11, and a height-adjustable telescopic tube 12 is vertically fixed on the floor base. The pipe fitting is fixed to the upper end of the telescopic tube. The height of the pipe fitting is adjusted through the telescopic tube.

[0034] In this embodiment, a fixed seat 21 is installed on the electric telescopic rod. The fixed seat is sleeved on the upper end of the telescopic tube and locked by bolts, so as to facilitate disassembly and assembly.

[0035] In this embodiment, the telescopic tube is composed of at least two pipes sleeved one by one, and after the pipes are extended to the required positions, they are locked by radial bolts.

[0036] In this embodiment, the sizes of the rods of the adjustable framework can be adjusted to adapt to different window sizes, but the overall structure and working principle remain unchanged.

[0037] In this embodiment, as Figure 5 shown: 80C51 is a 51 single-chip microcomputer; K0, K1, and K2 are the motor forward rotation switch, the motor reverse rotation switch, and the motor stop switch respectively; L298 is a motor drive module, ADC0832 is an analog-to-digital conversion module, and MPX4115 is a pressure sensor. Circuit working principle: After pressing the motor reverse rotation switch, the motor rotates in reverse. When it is detected that the pressure sensor reaches a specified value (this value can be adjusted according to the usage situation), the reverse rotation of the motor is blocked, but the forward rotation of the motor is not affected.

[0038] Specific implementation action process and principle of achieving protection: The device framework is equipped with fabric materials. After assembling all components, place the device on the ground at a certain distance in front of the window. Control the motor in the electric push-pull rod to reverse, causing the telescopic rod to contract inward, thereby making the connecting rod and the support rod expand outward until they contact the outer edge of the window and reach a certain supporting force, at which point the motor automatically stops. In this way, the outside of the window can be covered. When debris falls onto the fabric surface of the device, it can catch the debris or bounce it back into the room, thus preventing it from falling downstairs. When controlling the motor of the electric push-pull rod to rotate forward to extend the push rod, the lever mechanism can be used to make the connecting rod contract inward, achieving the purpose of retracting the mechanism.

[0039] If terms such as "first" and "second" are used in the present utility model to limit components, those skilled in the art should be aware that the use of "first" and "second" is only for the convenience of differentiating components in the description. Unless otherwise stated, the above terms have no special meaning.

[0040] If the present utility model discloses or involves components or structural members that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, using bolts or screws), or it can also be understood as: an inseparable fixed connection (for example, riveting, welding). Of course, the mutually fixed connection can also be replaced by an integral structure (for example, manufactured by integral casting process) (except when it is clearly impossible to use the integral forming process).

[0041] In addition, for the terms used to represent positional relationships or shapes in any of the technical solutions disclosed in the present utility model, unless otherwise stated, their meanings include states or shapes that are approximate, similar, or close to them.

[0042] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.

[0043] The above are only the preferred embodiments of the present utility model. All equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
