Problems solved by technology

The existing guardrail is generally fixed on the wall near the window by expansion bolts, but once the guardrail is fixed, it cannot be moved or expanded to the outside of the window, so it has certain limitations
At the same time, after living in high-rise buildings, every household has installed protective fences. The protective fences of the downstairs residents provide convenience for thieves and bring many unsafe threats to the upstairs residents.
But people often neglect the safety of the guardrails in high-rise buildings, and seldom set up alarm devices

Embodiment 1

[0017] Such as figure 1 , 3 As shown, a safe and reliable retractable window guardrail includes a fixed frame 3, an outer guardrail 2 and an infrared alarm device. The fixed frame 3 is fixed on the wall 1 by expansion bolts, and the window is enclosed in the fixed frame 3. The size of the fixed frame 3 is adapted to the size of the guardrail 2, and the movement between the fixed frame 3 and the outer guardrail 2 A crank arm 7 is connected, and one end of the crank arm 7 is provided with a power device 8 for driving the crank arm 7 to rotate. The crank arm 7 is composed of two mutually hinged pipes or plates, which can rotate around each other. There are four power units 8 and four curved arms 7, which are respectively installed at the four vertices of the fixed frame 3 and the outer layer guardrail 2 in one-to-one correspondence. There are four curved arms, and the four curved arms are respectively connected one by one at the four vertices of the outer protective fence ...

Embodiment 2

[0024] On the basis of Embodiment 1, the power device 8 is a motor, and the output shaft of the motor is connected to one end of the crank arm 7, and drives the crank arm 7 to rotate, and adjusts the distance between the fixed frame and the outer protective fence, thereby realizing the protective fence. The space is adjustable.

Embodiment 3

[0026] On the basis of the first embodiment, the power device 8 is a handle, and one end of the handle is connected with one end of the crank arm 7 . By shaking the handle, the crank arm 7 is driven to rotate, and the distance between the fixed frame and the outer protective fence is adjusted, so that the space of the protective fence can be adjusted.

Abstract

The invention discloses a contractible window protective guard reliable in safety. The contractible window protective guard reliable in safety comprises an outer layer protective guard, an infrared alarm device and a fixing frame matched with the outer layer protective guard, wherein the fixing frame is fixed to a wall face through expansion bolts and surrounds a window, a stretching mechanism used for adjusting the distance between the fixing frame and the outer layer protective guard is connected between the fixing frame and the outer layer protective guard, guardrails I connected with the fixing frame are arranged at the left side, the right side and the bottom surface of the outer layer protective guard respectively, each guardrail I is formed by mutually hinging a plurality of overlapped pieces, the two ends of each guardrail I are hinged to the fixing frame and the outer layer protective guard respectively, the outer layer protective guard comprises a protective guard framework and two sets of guardrails II, each guardrail II is installed inside sliding grooves of the protective guard framework through idler wheels at two ends of the guardrail II and slides left and right along the sliding grooves, the infrared alarm device is provided with an infrared emitter and an infrared receiver, and the infrared emitter and the infrared receiver are arranged on the two sets of guardrails II respectively. The contractible window protective guard reliable in safety widens the space conveniently and rapidly, is good in anti-theft effect, and is reliable in safety.

Description

technical field [0001] The invention relates to the field of building facilities, in particular to a safe and reliable retractable window guardrail arranged outside windows of houses. Background technique [0002] In recent years, with the increase of the urban population, the ground space can no longer meet the needs of the urban population, so high-rise buildings have sprung up, and people have moved into the high-rise buildings. For safety, people usually add protective barriers outside their windows to prevent people or objects from falling down from the windows, and also play a certain role in preventing theft. The existing guardrail is generally fixed on the wall near the window by expansion bolts, but once the guardrail is fixed, it cannot be moved or expanded to the outside of the window, so it has certain limitations. At the same time, after living in high-rise buildings, every household has installed protective fences. The protective fences of the downstairs r...
