[0001] The utility model relates to the technical field of plastic -steel door and window, concretely relates to a push -pull type plastic -steel door and window. BACKGROUND

[0002] Plastic -steel door and window are with polyvinyl chloride (UPVC) resin as main raw material, plus certain proportion stabilizer, colorant, filler, ultraviolet absorber etc., extrusion profile is then made through cutting, welding or screwing way and is made into door and window frame, is equipped with sealing strip, wool, hardware and so on, at the same time for reinforcing the rigidity of profile, the cavity of more than certain length profile needs to fill steel lining (reinforcing rib), and the door and window made in this way are called plastic -steel door and window. It has good safety and practical effect, and the production cost is lower, and is widely used in various fields. However, the existing push -pull type plastic -steel door and window is easy to wear after long time use, the sealing effect is poor, and the sealing strip is not convenient to replace quickly, thereby affecting the sealing property of the push -pull type plastic -steel door and window.

[0003] For example, China patent CN214576537U discloses a push -pull type plastic -steel door and window, including installation frame, first window frame and second window frame, the inner side upper surface and lower surface of installation frame are equipped with two slide rails, the first window frame and the second window frame are installed on the slide rail in staggered movement, the first window frame and the second window frame are installed with the scraper for cleaning the sundries in the inner side of installation frame along the two side faces of self -movement, the both ends of slide rail are equipped with the scrap container containing sundries, the installation frame above scrap container is equipped with rectangular hole.

[0004] The push -pull type plastic -steel door and window has the following shortcomings: although the sundries in the inner side of installation frame are pushed to the end angle of installation frame by scraper when the first window frame and the second window frame move, at this time, the sundries can fall into the scrap container through the rectangular hole to realize the collection of sundries, and the scrap container can be cleaned by pulling, but the sealing strip is easy to wear after long time use, the sealing effect is poor, and the sealing strip is not convenient to replace quickly, thereby affecting the sealing property of the push -pull type plastic -steel door and window.

[0005] For the problems in the related art, no effective solution has been proposed so far. SUMMARY

[0006] In view of the problems in the related art, the utility model provides a push -pull type plastic -steel door and window to overcome the above technical problems existing in the prior art.

[0007] Therefore, the utility model adopts the specific technical scheme as follows:

[0008] The utility model provides a kind of push-pull type plastic steel door and window, including plastic steel mounting frame, plastic steel window frame one and plastic steel window frame two, the structure of plastic steel window frame one and plastic steel window frame two is same, the inner top and bottom of plastic steel mounting frame are provided with slide rail, plastic steel window frame one and plastic steel window frame two are misaligned and movably installed on slide rail, one side of plastic steel window frame one is provided with clamping groove, the inside both ends side wall of clamping groove is provided with sealing strip, the top and bottom end of sealing strip are provided with fixed assembly, the inside both ends side wall of the top and bottom of clamping groove is provided with the installation hole matched with fixed assembly.

[0009] Further, in order to achieve the sound insulation, sealing, waterproof and impact resistance effect of the push-pull type plastic steel door and window under the action of the sealing strip, the durability of the sealing strip itself is improved, thereby improving the sealing effect of the push-pull type plastic steel door and window.

[0014] 3. By setting up a fixing component, when the sealing strip needs to be installed, the fixing component is placed inside the fixing component, and then the rotating shaft is turned forward to make the rotating shaft rotate forward with the rotating hole 1 as the center, and with the cooperation of the rotating hole 2 and the limiting rod, the limiting rod is moved away from the fixed shaft. When the limiting rod is away from the fixed shaft, the insertion rod moves outward in the slide groove. When the end of the insertion rod moves into the insertion hole, the rotation of the rotating shaft is stopped, so that the sealing strip can be installed on the side walls at both ends of the slot. When the sealing strip needs to be replaced, When the strip is moved, the rotating shaft is twisted to reverse, so that the rotating shaft is reversed with the rotating hole one as the center, and with the cooperation of the rotating hole two and the limiting rod, the limiting rod is close to the fixed shaft. When the limiting rod is close to the fixed shaft, the plug rod moves inward in the slide groove. When the end of the plug rod leaves the inside of the insertion hole, the rotating shaft is stopped from being twisted, and the sealing strip can be removed from the side walls at both ends of the slot for replacement, thereby realizing quick installation and removal of the sealing strip, improving the convenience of the sliding plastic steel door and window, and having a wider applicability.
