Technical Field

[0001] The utility model relates to the technical field of wood-plastic doors and windows, in particular to a flame-retardant and sound-absorbing wood-plastic door and window. Background Art

[0002] Wood-plastic doors and windows are made of a mixture of ultra-fine wood powder and polymer resin through a molding process. They have the excellent properties of both wood and plastic, and the products produced achieve a true wood-like effect. Because the raw materials used and the production process do not use glue, they will not produce harmful substances such as formaldehyde, benzene, ammonia, and trichloroethylene. They are a green and environmentally friendly new material to replace traditional wood.

[0003] Among them, the window sashes and window frames of wood-plastic doors and windows are pressed together by sealing strips to improve the sound insulation effect after closing. Therefore, the sealing strip sound-absorbing structure used in traditional wood-plastic door and window structures is relatively simple. If a gap appears between the sealing strip and the window frame due to factors such as aging of the sealing strip, the existing door sash sound insulation structure will be destroyed. In addition, the wood-plastic window has a poor flame retardant effect. In the event of a fire, the wood-plastic window is very likely to become a flame retardant, increasing the safety hazard. Therefore, the present application designs a flame retardant and sound-absorbing wood-plastic door and window to solve this technical defect of the prior art. Utility Model Content

DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1 to 4 The fire-retardant sound-damping wood-plastic door and window in the embodiments of the present application comprises a door frame 1 and a door leaf 2 hinged to the front side of the door frame 1, wherein the door frame 1 and the door leaf 2 are both made of wood-plastic material, and the bodies of the door frame 1 and the door leaf 2 are covered with a high-temperature-resistant layer and a fire-retardant layer on the outside to improve the fire-retardant effect, thereby reducing the possibility of the wood-plastic window becoming a fuel in a fire.

[0033] It is additionally pointed out that the side of the door frame 1 away from the door leaf 2 extends to form a buckling plate for contacting and blocking the door leaf 2, which makes the longitudinal section of the door frame 1 have an L-shaped structure.

[0034] Further, the door leaf 2 is provided with a glass mounting groove 5, and the glass 3 is arranged in the glass mounting groove 5. The glass 3 is specifically three-layer hollow glass, which is used to improve the sound insulation effect of the door and window. The front surface of the door frame 1 is further fixedly provided with a hardware handle 4, which is used to complete the opening and closing locking of the door leaf 2.

[0035] In the embodiment, the door frame 1 and the door leaf 2 are both hollow structures, and the steel structure lining 6 is embedded in the door frame 1 and the door leaf 2 to improve the overall strength of the door and window.

[0036] In this way, on the one hand, the overall quality of the door and window is reduced, and on the other hand, multiple independent cavities can be formed in the door frame 1 and the door leaf 2, and the multi-cavity heat insulation strip can be arranged in the door frame 1 or the door leaf 2, so that a vertical isothermal design can be formed to improve the heat preservation capacity of the door and window.

[0037] Further, the door leaf 2 is provided with a sealing strip mounting groove, which includes a first mounting groove 201, a second mounting groove 202 and a third mounting groove 203,

[0038] The side surface of the door leaf 2 away from the door frame 1 extends to form an L-shaped corner, the second mounting groove 202 is located on the corner surface of the door leaf 2, and the first mounting groove 201 is vertically distributed relative to the second mounting groove 202.

[0039] In this way, it can be ensured that the extended corner vertical surface of the door leaf 2 contacts the door frame 1 through the sealing strip to improve the sealing effect.

[0040] Notably, the inner side surface of the door frame 1 is recessed with a circular-arc-shaped groove corresponding to the third mounting groove 203, so that the positioning of the sealing strip between the door frame 1 and the door leaf 2 is stable.

[0041] In order to improve the contact effect of the sealing strip between the door frame 1 and the door leaf 2, the door frame 1 is provided with a pressing structure corresponding to the position of the first mounting groove 201, which can extrude the sealing strip arranged in the first mounting groove 201 to improve the contact effect of the sealing strip.

[0042] In the embodiment, the door frame 1 is provided with a receiving cavity 101 corresponding to the position of the first mounting groove 201, and the pressing structure includes an actuator, a sliding plate 102 and a pressure head 7 arranged in the receiving cavity 101.

[0043] In use, the sliding plate 102 is pushed by the actuator and acts on the pressure head 7, so that additional force can be applied to the sealing strip, and the sealing strip can be tightly pressed.

[0044] Furthermore, a mounting seat 103 is fixedly installed on the slide 102, and the pressure head 7 is fixedly connected to the mounting seat 103 for being set on the slide 102. At the same time, the upper end of the pressure head 7 and the upper end of the accommodating cavity 101 slide with each other, so that the lifting activity of the pressure head 7 is stable.

[0045] Furthermore, a boss 8 is integrally extended from the bottom of the slide plate 102 , and the actuator includes a slide 10 that slides in the accommodating cavity 101 , with the end of the slide 10 contacting the boss 8 .

[0046] It should be noted that the longitudinal cross-section of the boss 8 is a right-angled trapezoid, and the inclined end of the boss 8 and the end of the slide 10 are in contact with each other.

[0047] With this design, the slide plate 102 connected to the boss 8 can be forced to lift and slide in the accommodating cavity 101 under the horizontal push of the slide table 10.

[0048] In order to improve the contact stability of the slide 10 relative to the boss 8, the cross-section of the slide 10 close to the boss 8 is semicircular, so the end of the slide 10 is in an arc shape and contacts the inclined surface of the boss 8, so that under the extrusion of the slide 10, the boss 8 moves in position, and the two can still maintain good contact.

[0049] In this embodiment, a guide bar 9 is fixedly installed on the inner bottom wall of the accommodating cavity 101. The guide bars 9 include several guide bars 9, and all of them pass through the slide 10. A straight slot is opened on the slide 10 for horizontal sliding relative to the guide bar 9 to facilitate the positioning of the horizontal sliding of the slide 10.

[0050] In order to cooperate with the closing action of the door leaf 2, a pressing pin 11 is fixedly installed on the end of the sliding platform 1 facing the outside of the door frame 1, and extends to the outside of the door frame 1. The pressing pin 11 is evenly distributed along the shape direction of the door frame 1, and the length of the pressing pin 11 extending straight outside the door frame 1 is in the range of 1-3mm.

[0051] Therefore, in actual use, the pressing pin 11 extending to the outside of the door frame 1 can be squeezed into the inside of the door frame 1 by closing the door leaf 2, and at the same time, the sealing strip between the door leaf 2 and the door frame 1 is squeezed, forcing the sealing strip to obtain sufficient extrusion force to improve the fitting effect.

[0052] The working principle of the above embodiment is: by rotating the door leaf 2 hinged to the door frame 1 relative to the door frame 1 until it fits the door frame 1, at this time the angled surface of the door leaf 2 contacts the outer side surface of the door frame 1, and the outer side surface of the door leaf 2 and the door frame 1 are closed by the contact of the sealing strips located on the first mounting groove 201, the second mounting groove 202 and the third mounting groove 203. At the same time, the pressing pin 11 extending to the outside of the door frame 1 is squeezed by the door leaf 2, so that the pressing pin 11 slides toward the door frame 1, and the slide 10 connected to the pressing pin 11 slides in the accommodating cavity 101, and is slid and squeezed toward the boss 8 through the slide 10, and the slide plate 102 is pushed to slide in the accommodating cavity 101. At this time, the pressure head 7 located on the slide plate 102 is lifted up to squeeze the sealing strip installed on the first mounting groove 201, so that the fitting effect of the sealing strip is improved and the sound insulation effect of the doors and windows is enhanced.
