All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 2-3, the present utility model is a door and window error preventer 100, which comprises an error preventing seat 1 and a sliding member 2 slidably connected with the error preventing seat 1. The error preventer 100 is used for being mounted on a door and window and matched with a frame of the door and window, the door and window is also provided with a driver 110 and a handle 120 matched with the driver 110, and an operator can rotate the handle 120 to drive the driver 110 to work, so that the door and window can be opened and closed. The driver 110 is also provided with a moving rod 111, the moving rod 111 is provided with an error-preventing protruding block 112 which is matched with the error-preventing device 100, and the error-preventing device 100 limits the movement of the driver 110 by clamping the error-preventing protruding block 112 so as to limit the movement of the brake rod 111, so that the handle 120 cannot be screwed, and the handle 120 is prevented from being screwed by error.
Referring to fig. 4-7, the anti-misoperation seat 1 has a first end and a second end opposite to each other, a sliding space 11 extending from the first end to the second end is disposed in the anti-misoperation seat 1, and a first opening 12 and a second opening 13 are respectively formed on the front and the back of the sliding space 11; two opposite guide hole parts 14 are arranged on two sides of the sliding space 11, and a spring 3 is arranged in each guide hole part 14;
the sliding member 2 is integrally formed, is inserted into the sliding space 11 from the first end of the error-preventing seat 1, can reciprocate between a first position and a second position along the extending direction of the sliding space 11, comprises a sliding sheet 21 and sliding blocks 22 arranged on two sides of the sliding sheet 21, wherein the sliding blocks 22 are arranged in the guide hole part 14, a push plate 23 which is vertical to the sliding sheet 21 and extends from the first opening 12 is arranged at the tail part of the front surface of the sliding sheet 21, and a limit area 24 arranged at the tail part and an unlocking area 25 arranged above the limit area 24 are arranged at the back surface of the sliding sheet 21;
when the sliding member 2 is located at the first position, the sliding piece 21 extends out of the sliding space 11 from the first end of the error preventing seat 1, the limiting area 24 is located in the second opening 13, and the unlocking area 25 is located at least partially outside the second opening 13; when the sliding member 2 is in the second position, the sliding piece 21 is located in the sliding space 11, and the limiting area 24 and the unlocking area 25 are both located in the second opening 13.
The error preventer 100 is used for being installed on a door or window, when the door or window is in a closed state, the frame of the door or window applies a force from the first end toward the second end of the error preventing seat 1 to the push plate 23, so that the compression spring 3 pushes the whole sliding member 2 to slide along the sliding space 11 toward the second end, and the error preventing protruding block 112 on the moving rod 111 is separated from the limiting area 24 and enters the unlocking area 25, so that the moving rod 111 of the driver 110 can move freely, and finally an operator can rotate the handle 120 to open the door or window. When the door and window is in the open state, the force applied on the push plate 23 disappears due to the separation of the frame of the door and window from the push plate 23, so that the whole sliding member 2 slides to the first end along the sliding space 11 under the rebound action of the spring 3 after losing the pressure, and the error-preventing bump 112 on the moving rod 111 is separated from the unlocking zone 25 to enter the limiting zone 24, thereby limiting the movement of the moving rod 111 of the driver 110, and finally enabling an operator to be unable to rotate the handle 120 under the condition that the door and window is opened. Thus, when the door and window is opened, the error preventing device 100 can automatically prevent the door and window from being damaged by rotating the handle 120 due to misoperation, and has simple and reliable structure and better working stability.
