In use, the positioning cap 621 is rotated and the positioning bar 622 slides in the guide ramp 614 to effect axial movement of the positioning pin 62 such that the positioning bar 622 slides from the first positioning portion 612 into the second positioning portion 613 or from the second positioning portion 613 into the first positioning portion 612.
As a preferable mode of the present invention, the first positioning portions 612 and the second positioning portions 613 are two, the two first positioning portions 612 are provided at both ends of the positioning column 61 in the radial direction, and the two second positioning portions 613 are provided at both ends of the positioning column 61 in the radial direction.
As a preferred mode of the present invention, the number of the positioning strips 622 is two, two positioning strips 622 are disposed on the inner wall of the positioning cap 621, and two positioning strips 622 are disposed on two radial ends of the positioning cap 621.
As a preferable mode of the present invention, the positioning pin 62 is provided with an annular groove 623, and the clamping portion is a clamping ring 624 clamped in the annular groove 623.
As a preferable mode of the present invention, the elastic member is a spring 63, one end of the spring 63 abuts against the snap ring 624, the other end abuts against the support table 615, when the positioning bar 622 slides from the first positioning portion 612 to the second positioning portion 613, the snap ring 624 compresses the spring 63, the positioning cap 621 does not automatically loosen under the action of the spring 63, and when the positioning bar 622 slides from the second positioning portion 613 to the first positioning portion 612, the spring 63 can push the positioning pin 62 to axially move.
As a preferred mode of the present invention, the mounting base 60 is provided with a clamping base 64, the clamping base 64 is provided with a first screw hole pillar 641, the first screw hole pillar 641 is provided with a first screw 642, the first screw 642 extends out of the mounting base 60, and the safety positioner 600 of the present invention is mounted at a corresponding position of a door or window through the first screw 642.
In a preferred mode of the present invention, a second screw hole post 643 is further provided in the clamping seat 64, a cover plate 645 is provided on the mounting seat 60, and the cover plate 645 is locked in the second screw hole post 643 by a second screw 644.
As a preferred mode of the present invention, the present invention further comprises a fixing frame 701, the mounting frame 702 is mounted on the fixing frame 701 in a manner of being capable of being pushed and pulled inside and outside through a hinge, a handle 705 is provided on the mounting frame 702 to facilitate the opening of the mounting frame 702, in order to limit the opening degree of the inner fan and the outer fan, a corresponding stop block 706 is provided on the fixing frame 701, and the inner fan or the outer fan is limited when moving to the position of the stop block 706. The invention can also provide corresponding safety nets on the mounting frame 702 as required.
The side-hung lifting door and window has stable lifting of the window sashes, no noise, excellent air tightness, excellent water tightness and excellent safety.
The product form of the present invention is not limited to the embodiments described herein, and any suitable variations or modifications of the similar concept should be regarded as not departing from the scope of the invention.
