Low-energy door and window with high sealing performance

Abstract

This utility model relates to the field of door and window technology, specifically to a low-energy-consumption door and window with high sealing performance, comprising four sets of frames, with two frames connected by connecting corner blocks. Each frame includes an H-shaped frame beam. This utility model allows expanding foam to flow into the expanding foam filling section through the feeding guide. The expanding foam filling section is gradually filled with expanding foam. Under the guiding action of the pushing inclined section, the expanding foam accumulates to the rear. When a certain amount of expanding foam is injected, it overflows from the front of the frame. During the insertion process, the hexagonal head of the self-tapping screw squeezes the hard rubber retaining ring at the inner end of the hard rubber cylinder, causing the hard rubber cylinder to move outward within the first through hole. Under the guiding action of the discharge guide and the pushing inclined section, as well as the blocking action of the feeding guide, the expanding foam overflows into the rear gap between the frame and the wall, thereby improving the sealing performance between the frame and the wall.

Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a low-energy door and window with high sealing performance. Background Technology

[0002] Doors and windows are an important component of the building envelope system. Depending on their location, doors and windows are classified as enclosure components or partition components, and have different design requirements. In addition, doors and windows generally also play a certain role in heat preservation, heat insulation, and sound insulation.

[0003] Traditionally, when installing door and window frames to walls, the gaps are typically sealed by filling them with expanding foam from the inside of the house, followed by fixing with self-tapping screws. Uneven walls inevitably create gaps of varying sizes between the doors / windows and the walls. Larger gaps require more expanding foam, and applying foam from the outside is inconvenient, often resulting in uneven application and poor sealing. Consequently, when air conditioning or other temperature-controlled systems are used indoors, air circulation makes it difficult to maintain a stable indoor temperature, leading to energy loss and increased energy consumption. Therefore, we propose a low-energy-consumption door and window with high sealing performance to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-energy-consumption door and window with high sealing performance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-energy-consumption door and window with high sealing performance, comprising four sets of frames, two of which are connected by connecting corner blocks. Each frame includes an H-shaped frame beam, and two trapezoidal blocks are provided inside the side of the H-shaped frame beam that contacts the wall. A trapezoidal plate is slidably connected to the outer area of ​​the H-shaped frame beam. Two first through holes are provided inside the H-shaped frame beam, and two second through holes are provided on the trapezoidal plate. Self-tapping bolts are inserted into the first and second through holes, and the frame is fixedly connected to the wall by means of the self-tapping bolts.

[0006] More preferably, the diameter of the first through hole is larger than the diameter of the second through hole, the diameter of the second through hole is larger than the diameter of the self-tapping bolt shank, and a hard rubber cylinder is provided between the self-tapping bolt and the first through hole.

[0007] More preferably, the rigid rubber cylinder is in movable contact with the threaded part of the self-tapping bolt and the inner wall of the first through hole, and rigid rubber retaining rings are fixedly connected to both ends of the rigid rubber cylinder, the diameter of the rigid rubber retaining rings being larger than the diameter of the first through hole.

[0008] More preferably, the inclined surface of the trapezoidal plate is configured as a pushing inclined surface, which is configured to be higher at the front and lower at the rear.

[0009] More preferably, a foam filling section is set between the pusher slope and the left side area of ​​the H-shaped frame beam for sealing between the frame and the wall. When the self-tapping bolt is wedged into the wall, the hexagonal screw head pushes the hard rubber cylinder to move the trapezoidal plate outward, and the foam in the foam filling section is squeezed out. With the setting of the pusher slope of the trapezoidal plate, the foam overflows to the rear, thereby effectively improving the sealing between the frame and the wall.

[0010] More preferably, the inclined surfaces of the two trapezoidal blocks are placed in opposite directions, with the inclined surface of the front trapezoidal block facing outward to form a feed guide section, and the inclined surface of the rear trapezoidal block facing inward to form a discharge guide section.

[0011] More preferably, the frame and the connecting corner block are fixedly connected by multiple screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the frame is fixedly connected to the connecting corner blocks with screws. Then, the assembled frame is placed at the reserved window frame position on the wall. Excess expanding foam is injected from inside the room into the connection between the frame and the wall. The expanding foam flows into the expanding foam filling part through the feeding guide part. The expanding foam filling part is gradually filled with expanding foam. Under the guiding action of the pushing inclined part, the expanding foam accumulates to the rear side. When a certain amount of expanding foam is injected, it overflows from the front side of the frame. At this time, self-tapping screws are sequentially inserted into the first through hole and the second through hole. Inside, a self-tapping screw is driven into the wall using an electric drill. During the driving process, the hexagonal head of the self-tapping screw squeezes the hard rubber retaining ring on the inner end of the hard rubber cylinder, causing the hard rubber cylinder to move outward in the first through hole. The hard rubber retaining ring on the outer end of the hard rubber cylinder pushes the trapezoidal plate. The pusher slope of the trapezoidal plate pushes the excess foam in the foam filling part. Under the guiding action of the discharge guide part and the pusher slope, as well as the blocking action of the feed guide part, the foam overflows into the gap between the frame and the wall, thereby improving the sealing between the frame and the wall.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1-5This utility model provides a technical solution: a low-energy-consumption door and window with high sealing performance, comprising four sets of frame bodies 1, with two frame bodies 1 connected by connecting corner blocks 2. Each frame body 1 includes an H-shaped frame beam 3, with two trapezoidal blocks 4 disposed inside the side of the H-shaped frame beam 3 that contacts the wall. A trapezoidal plate 7 is slidably connected to the outer area of ​​the H-shaped frame beam 3. Two first through holes 9 are opened inside the H-shaped frame beam 3, and two second through holes are opened on the trapezoidal plate 7. Self-tapping screws 12 are inserted into the first and second through holes 9 and 2 through holes, respectively, to fix the frame body 1 to the wall. In use, the frame body 1 is fixedly connected to the connecting corner blocks 2 using screws 14. Then, the assembled frame body 1 is placed at the pre-reserved window frame position on the wall. Excessive expanding foam is injected from inside the room into the connection between the frame body 1 and the wall. The expanding foam flows into the expanding foam filling part 13 through the feeding guide part 5. Foam is gradually filled into the filling part 13. Under the guiding action of the pusher slope 8, the foam accumulates to the rear. When a certain amount of foam is injected, it overflows from the front of the frame 1. At this time, the self-tapping bolts 12 are sequentially inserted into the first through hole 9 and the second through hole. The self-tapping bolts 12 are driven into the wall using an electric drill. During the driving process, the hexagonal head of the self-tapping bolts 12 squeezes the hard rubber retaining ring 11 at the inner end of the hard rubber cylinder 10, causing the hard rubber cylinder 10 to move outward in the first through hole 9. The hard rubber retaining ring 11 at the outer end of the hard rubber cylinder 10 pushes the trapezoidal plate 7. The pusher slope 8 of the trapezoidal plate 7 pushes the excess foam in the foam filling part 13. Under the guiding action of the discharge guide part 6 and the pusher slope 8, and the blocking action of the feed guide part 5, the foam overflows into the gap between the frame 1 and the wall, thereby improving the sealing between the frame 1 and the wall.

[0021] In this embodiment, specifically: the diameter of the first through hole 9 is larger than the diameter of the second through hole, the diameter of the second through hole is larger than the diameter of the screw portion of the self-tapping screw 12, and a hard rubber cylinder 10 is provided between the self-tapping screw 12 and the first through hole 9.

[0022] In this embodiment, specifically: the hard rubber cylinder 10 is in movable contact with the screw part of the self-tapping bolt 12 and the inner wall of the first through hole 9. Hard rubber retaining rings 11 are fixedly connected to both ends of the hard rubber cylinder 10, and the diameter of the hard rubber retaining rings 11 is larger than the diameter of the first through hole 9.

[0023] In this embodiment, specifically: the inclined surface of the trapezoidal plate 7 is set as a pushing inclined surface 8, and the pushing inclined surface 8 is set with the front side higher than the rear side;

[0024] In this embodiment, specifically: a foam filling part 13 is set between the pusher inclined part 8 and the left side area of ​​the H-shaped frame beam 3. The foam filling part 13 is filled with excess foam for sealing between the frame 1 and the wall. When the self-tapping bolt 12 is wedged into the wall, the head of the hexagonal screw pushes the hard rubber cylinder 10 to move the trapezoidal plate 7 outward. The foam in the foam filling part 13 is squeezed out. With the setting of the pusher inclined part 8 of the trapezoidal plate 7, the foam overflows to the rear, thereby effectively improving the sealing between the frame 1 and the wall.

[0025] In this embodiment, specifically: the inclined surfaces of the two trapezoidal blocks 4 are placed in opposite directions, with the inclined surface of the front trapezoidal block 4 facing outward to form the feed guide section 5, and the inclined surface of the rear trapezoidal block 4 facing inward to form the discharge guide section 6.

[0026] In this embodiment, specifically, the frame 1 and the connecting corner block 2 are fixedly connected by multiple screws 14.

[0027] In operation, this utility model is used as follows: The frame 1 is fixedly connected to the connecting corner block 2 using screws 14. The assembled frame 1 is then placed at the pre-reserved window frame position on the wall. Excess expanding foam is injected from inside the room into the connection between the frame 1 and the wall. The expanding foam flows through the feed guide 5 into the expanding foam filling part 13, which is gradually filled. Under the guiding action of the pusher inclined part 8, the expanding foam accumulates to the rear. When a certain amount of expanding foam has been injected, it overflows from the front of the frame 1. At this point, self-tapping screws 12 are sequentially inserted into the first through hole 9 and the second through hole. An electric drill is then used to drill the self-tapping screws 12 into the first through hole 9 and the second through hole. 2. When the self-tapping bolt 12 is driven into the wall, the hexagonal head of the self-tapping bolt 12 squeezes the hard rubber retaining ring 11 on the inner end of the hard rubber cylinder 10 during the driving process, causing the hard rubber cylinder 10 to move outward in the first through hole 9. The hard rubber retaining ring 11 on the outer end of the hard rubber cylinder 10 pushes the trapezoidal plate 7. The pusher slope 8 of the trapezoidal plate 7 pushes the excess foam in the foam filling part 13. Under the guiding action of the discharge guide part 6 and the pusher slope 8, and under the blocking action of the feed guide part 5, the foam overflows into the gap between the frame 1 and the wall, thereby improving the sealing between the frame 1 and the wall.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
