Anti-pinch window opener

Abstract

This utility model provides an anti-pinch window opener, belonging to the field of window opener technology. Addressing the problem that over-reliance on sensors leads to delays in response when the sensors are interfered with or other objects are present, affecting window opening and closing, this utility model features an anti-pinch mechanism on one side of the window opener body and an emergency stop mechanism on the other side. The anti-pinch mechanism retracts when the window opener body is about to pinch a person, and the emergency stop mechanism stops the window opener body from pinching a person again. The anti-pinch mechanism, connecting both sides, softens under excessive pressure during retraction to prevent injury to the worker's hand. The emergency stop mechanism not only prevents injury but also stops the window from closing when squeezed, providing a secondary anti-pinch function.

Description

Technical Field

[0001] This utility model relates to the field of window opener technology, specifically to an anti-pinch window opener. Background Technology

[0002] With the continuous progress of society and the continuous development of science and technology, the things people use in their daily lives are gradually becoming automated. In order to improve convenience, people will install window openers in high-mounted windows, windows that are too heavy, and in locations where indoor temperature requirements are high. The window openers can be used to intelligently open and close sliding windows and can also be remotely controlled, making them very convenient to use.

[0003] For example, in the public disclosure (CN217501399U), an anti-pinch sliding window opener is installed on one side of the top of the main body. The touch sensor detects whether there is an object touching the top and transmits the detection result to the internal part of the single-sided machine for analysis. When a human body touches the touch sensor, the single-sided machine will automatically activate the alarm and prompt people to move their hands to the outside of the main body to prevent the human body from being pinched and causing personal injury when opening and closing the window. However, the following problems still exist in the use of this device.

[0004] The window opener relies entirely on sensors during use. If the sensors malfunction, they can still trap the worker's arm or hand. Slow sensor signal transmission or other objects above the window can also prevent the window from closing, affecting its effectiveness.

[0005] In summary, designing a window opener that can guarantee rapid response and prevent pinching injuries without relying on sensors becomes particularly important. Utility Model Content

[0006] The purpose of this invention is to overcome the problem in the above-mentioned background technology that relies too much on sensors, and that when the sensors are interfered with or there are other objects, they cannot react in time, thus affecting the opening and closing of the windows.

[0007] Based on the above technical ideas, the technical solution adopted by this utility model is as follows: by setting an anti-pinch mechanism that connects both sides, the anti-pinch mechanism will soften if it is subjected to excessive pressure during the recycling process to avoid pinching the worker's hand. In addition, by setting an emergency stop mechanism, on the one hand, it avoids pinching injury, and on the other hand, squeezing the emergency stop mechanism will stop the window from closing, thus performing secondary anti-pinch.

[0008] An anti-pinch window opener includes a main body. An anti-pinch mechanism is located on one side of the main body, and an emergency stop mechanism is located on the other side. The anti-pinch mechanism retracts the main body when it is about to pinch a person, and the emergency stop mechanism brings the main body to an abrupt stop when it is about to pinch a person. The anti-pinch mechanism further includes a support column, a sliding rod, an alloy memory spring, a primary anti-detachment block, and a secondary anti-detachment block. The support column is centrally connected to the alloy memory spring, and the sliding rod is also centrally connected to the support column. The sliding rod limits the movement of the support column to prevent it from wobbling.

[0009] Further defining the above technical solution, an installation component is provided on one side of the window opener body. The installation component consists of a threaded sleeve and a threaded pin, which are used to fix and install the window opener body. The installation component allows for quick installation of the window opener body, facilitating subsequent use.

[0010] Further defining the above technical solution, a rotating disk is connected to the top of the main body of the window opener, and an installation block is connected to the outside of the rotating disk. The installation block is used to connect the rotating disk and the support column. By cooperating with the support column, the rotating disk drives the slide rail to automatically reset, thereby realizing automatic opening and closing.

[0011] Further defining the above technical solution, the inner side of the support column is provided with a sliding groove for connecting the sliding rod, and the edge of the support column is also connected with a primary anti-detachment block for engaging a secondary anti-detachment block. The primary and secondary anti-detachment blocks cooperate to prevent the sliding rod from falling off.

[0012] Further defining the above technical solution, the sliding rod and the support column are connected in a sliding connection manner, and a secondary anti-detachment block is connected to the other side of the sliding rod to prevent the sliding rod from detaching from the support column. The secondary anti-detachment block limits the sliding rod and prevents the support column from moving.

[0013] Further defining the above technical solution, the emergency stop mechanism also includes a slide rail, a connecting block, protective rubber, a sensor, and a touch switch. The protective rubber is evenly and equidistantly distributed on the outer side of the slide rail, and a connecting block is connected below the slide rail to connect the slide rail and the support column.

[0014] Further defining the above technical solution, sensors are symmetrically distributed on the inner side of the protective rubber, and a touch switch is connected to the other side of the sensor. The touch switch is used to stop the rotating disk in an emergency. The purpose of emergency stop is achieved by the cooperation of the sensor and the touch switch.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Automatic retraction: By setting an alloy memory spring at the center of the support column, if the hand is above the main body of the window opener, the slide rail touches the hand, which increases the pressure, and the alloy memory spring softens instantly, causing the support column to retract and avoid pinching the hand. At the same time, a sliding rod is also connected to the center of the support column to prevent the support column from moving.

[0017] (2) Induction switch: By setting protective rubber and sensor on the inside of the slide rail, when the slide rail is about to clamp the hand, the hand squeezes the protective rubber, causing the sensor to move inward, so that the sensor touches the touch switch, causing the window opener to stop working and avoid pinching the hand.

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0025] This embodiment provides an anti-pinch window opener, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a window opener body 1. An anti-pinch mechanism 4 is provided on one side of the window opener body 1. This mechanism retracts the window opener body 1 when it is about to pinch a person. An installation component 11 is provided on one side of the window opener body 1. The installation component 11 consists of a threaded sleeve and a threaded pin, used to fix and install the window opener body 1. The installation component 11 allows for quick installation of the window opener body 1, facilitating subsequent use. A rotating disk 2 is connected to the top of the window opener body 1. An installation block 3 is connected to the outer side of the rotating disk 2. The installation block 3 connects the rotating disk 2 and the support column 401. The rotating disk 2, in cooperation with the support column 401, drives the slide rail 501 to automatically reset, achieving automatic opening and closing.

[0026] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment of the invention, the anti-pinch mechanism 4 further includes a support column 401, a sliding rod 402, an alloy memory spring 403, a primary anti-detachment block 404, and a secondary anti-detachment block 405. The center of the support column 401 is connected to the alloy memory spring 403, and the center of the support column 401 is also connected to the sliding rod 402. The sliding rod 402 is used to limit the support column 401 to prevent it from shaking. By limiting the support column 401, the two sides of the support column 401 are prevented from shaking and becoming misaligned. An opening is also provided on the inner side of the support column 401. There is a groove for connecting the sliding rod 402. The edge of the support column 401 is also connected to a primary anti-detachment block 404 for engaging a secondary anti-detachment block 405. The primary anti-detachment block 404 and the secondary anti-detachment block 405 cooperate to prevent the sliding rod 402 from falling off. The connection between the sliding rod 402 and the support column 401 is a sliding connection. The other side of the sliding rod 402 is connected to a secondary anti-detachment block 405 to prevent the sliding rod 402 from detaching from the support column 401. The secondary anti-detachment block 405 limits the sliding rod 402 and prevents the support column 401 from moving.

[0027] Combination Figure 1 and Figure 2 In this embodiment of the utility model, an emergency stop mechanism 5 is provided on the other side of the window opener body 1. The emergency stop mechanism 5 stops the window opener body 1 when it is about to trap a person. The emergency stop mechanism 5 also includes a slide rail 501, a connecting block 502, a protective rubber 503, a sensor 504, and a touch switch 505. The protective rubber 503 is evenly distributed on the outside of the slide rail 501. A connecting block 502 is also connected to the bottom of the slide rail 501 to connect the slide rail 501 and the support column 401. The connecting block 502 connects the slide rail 501 and the support column, which facilitates the movement of the slide rail 501. Sensors 504 are symmetrically distributed on the inside of the protective rubber 503. A touch switch 505 is connected to the other side of the sensor 504. The touch switch 505 is used to stop the rotating disk 2 in an emergency. The purpose of emergency stop is achieved by the cooperation of the sensor 504 and the touch switch 505.

[0028] Working principle: First, during use, the rotating disk 2 drives the support column 401 and the connecting block 502 to move through the mounting block 3. At this time, the connecting block 502 drives the slide rail 501 to move. If there is a hand placed above the window opener body 1, or if a hand is extended out of the window opener body 1 and placed between it and the slide rail 501, when the slide rail 501 drives the window to close, the protective rubber 503 on its inner side will first contact the hand. At this time, the hand squeezes the protective rubber 503, causing the sensor 504 to move inward and touch the touch switch 505, causing the rotating disk 2 to stop urgently to prevent the arm from being pinched.

[0029] As mentioned above, assuming that the sensor 504 reacts slowly due to an accident, or that the slide rail 501 continues to press towards the hand due to inertia, the pressure is transmitted to the support column 401 and the alloy memory spring 403 at its center. When the pressure increases instantaneously, the alloy memory spring 403 softens, and the support column 401 moves towards the center to avoid clamping the hand until the person has time to react and lift the hand. At this time, the sliding rod 402 slides inside the support column 401 to prevent the support columns 401 on both sides from becoming misaligned. After use, the alloy memory spring 403 resets and supports the different support columns 401 again.

[0030] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
