In addition, the size of the bolt 8 can be replaced or shortened according to actual conditions, various errors in the production process can be coped with, and the installation of the door and window is facilitated.

[0043] When the door and window need to be disassembled, the locking tongue 12 is lowered by rotating the adjusting knob 16, the locking tongue 12 is separated from the bolt 8, and then the sliding block 7 is separated from the locking part and the door and window. As can be seen from the above, by arranging the locking part, the disassembly process is fast and no other tools are needed, which effectively improves the work efficiency; and in an emergency, it can be quickly disassembled to avoid the situation that violent damage to the door and window is needed due to the short time.

[0044] An electric door and window adopts the electric door and window switch, which comprises a door and window upper slide 25, a door and window fan material 26, as shown in Figure 6 The guide sliding groove 1 of the electric door and window switch is installed in the door and window upper slide 25, and the lock box fixing piece 10 of the electric door and window switch is threadedly connected with the door and window fan material 26, so that the door and window fan material 26 is driven by the sliding block 7 and the lock box 9 to move along the axis direction of the lead screw 4.

[0045] Embodiment two, as shown in Figure 7 , Figure 8

[0046] Different from embodiment one, the flat steel 2 is provided with sliding block limiting units on both sides, and the sliding block limiting units are located on the inner sides of the first bearing box 5 and the second bearing box 6, respectively. The sliding block limiting unit comprises a limiting block 20 threadedly connected with the bottom surface of the flat steel 2, and the inner side of the limiting block 20 is provided with a proximity switch sliding block 21 which is slidingly connected with the bottom surface of the flat steel 2. Specifically, a sliding groove matched with a sliding protrusion connection mode can be selected, which is a prior art and will not be described in detail. The lead screw 4 penetrates the limiting block 20 and the proximity switch sliding block 21, but the lead screw 4 does not contact the limiting block 20 and the proximity switch sliding block 21. A stroke adjusting screw 22 is arranged between the limiting block 20 and the proximity switch sliding block 21. The stroke adjusting screw 22 comprises a nut and a screw rod, wherein the screw rod is divided into a smooth section and a threaded section in the direction away from the nut. The stroke adjusting screw 22 is inserted from the inner side of the proximity switch sliding block 21 and penetrates out from the outer side of the limiting block 20. The nut abuts against the proximity switch sliding block 21, and one end of the stroke adjusting screw 22 exposed from the limiting block 20 is fixed to the limiting block 20 by a nut.

[0047] A buffer spring 23 is arranged between the opposite surfaces of the limiting block 20 and the proximity switch sliding block 21, and the buffer spring 23 is sleeved on the periphery of the stroke adjusting screw 22. The inner side surface of the proximity switch sliding block 21 is further provided with a proximity switch 24. The proximity switch 24 is used for sensing the distance between the proximity switch sliding block 21 and the sliding block 7. The signal output end of the proximity switch 24 is electrically connected with the signal input end of a microcontroller (not shown in the figure). In this embodiment, the model of the microcontroller is 32F103C8, and the signal output end of the microcontroller is electrically connected with the motor 3.

[0048] ​When in use, the slider 7 slides along the screw rod 4, when the slider 7 approaches the proximity switch 24, that is, the slider 7 reaches the maximum stroke, the proximity switch 24 senses the position of the slider 7 and transmits a signal to the microcontroller, the microcontroller controls the motor to be turned off, the screw rod 4 stops driving while the slider 7 is not moving, so as to ensure that the slider 7 slides within the predetermined range.

[0049] However, under the action of the rotation inertia of the motor 3, when the motor 3 receives the signal of the microcontroller, the screw rod 4 will still rotate and the slider 7 will slide slightly, at this time, the slider 7 will contact the proximity switch slider 21, so that the proximity switch slider 21 slides along the stroke adjusting screw rod 22 and compresses the buffer spring 23, thereby buffering the slider 7 and protecting the motor 3 and the bearing box outside.

[0050] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
