Technical Field

[0001] This utility model belongs to the field of aluminum alloy door and window technology, and more specifically, it relates to a connection and fixing structure for aluminum alloy doors and windows. Background Technology

[0002] In the construction industry, aluminum alloy doors and windows are widely used due to their advantages such as lightweight, corrosion resistance, and excellent sealing performance. Traditional aluminum alloy door and window connections and fixing structures mostly employ screw fastening, welding, or corner bracket splicing. However, these methods have significant shortcomings. Firstly, welding damages the oxide film on the material surface, reducing the corrosion resistance of the doors and windows; moreover, the welding process is complex and requires highly skilled construction workers. Furthermore, traditional structures lack sufficient buffering capacity to cope with thermal expansion and contraction, easily leading to sealing failure and affecting the insulation and soundproofing effects of the doors and windows. To address these technical problems, this application proposes a solution. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a connection and fixing structure for aluminum alloy doors and windows. This fixing structure allows for faster installation of door and window frames and also changes the opening and closing method of doors and windows, making them more aesthetically pleasing.

[0004] The aforementioned aluminum alloy door and window connection and fixing structure includes a door and window fixing base and a door and window frame. The door and window frame is composed of four frames spliced ​​together. The frame has a groove inside, and multiple horizontal shafts are fixedly connected in the groove and horizontally arranged in the direction of the opening. Rubber wheels are rotatably connected to the horizontal shafts. Glass is placed inside the groove, and the glass abuts against the rubber wheels. Sealing strips are fixedly connected to the contact parts of the glass with the frame on both sides. Limiting holes are provided at both ends of the frame. A fixing mechanism is provided at the connection point of every two frames. The fixing mechanism includes an outer frame, which is "L"-shaped. Inside the outer frame, cylinders are fixedly connected in both the horizontal and vertical directions. Limiting gears are rotatably connected to the cylinders. Telescopic devices are meshed and driven on both sides of the limiting gears. The telescopic device includes a telescopic block that is slidably connected to the outer frame. A spring is fixedly connected to one side of the telescopic block, and one end of the spring is fixedly connected to the inside of the outer frame. A meshing toothed plate is provided on the side of the telescopic block near the limiting gear. The telescopic block is slidably connected to the limiting hole.

[0005] Preferably, a rotating wheel is fixedly connected to the middle position of the outer side of the upper and lower frames.

[0006] Preferably, the door and window fixing base includes an upper base and a lower base. The upper base has protrusions fixedly connected to both ends on one side. The bottom side of the protrusions has threaded holes that communicate with the upper base. The lower base is U-shaped, with grooves at the upper ends of the two protruding parts. Threaded holes are provided inside the grooves. The protrusions are slidably connected to the grooves. Bolts that fix the upper base and the lower base are threadedly connected inside the threaded holes. The bottom inner side of the lower base has an arc-shaped groove with two layers. The diameter of the groove on the upper layer near the frame is the same as the diameter of the rotating wheel, and the diameter on the other side is smaller than the diameter of the rotating wheel. The diameter of the lower layer is the same as the diameter of the rotating wheel.

[0007] Preferably, the arc-shaped groove is located near the middle of the lower base, and a locking mechanism is rotatably connected to the lower layer. The locking mechanism includes a gear rotatably connected to the lower base. A semi-circular baffle is fixedly connected above the gear. The semi-circular baffle is semi-circular, and one side of the inner side of the semi-circular baffle abuts against the outer surface of the rotating wheel. The upper surface of the gear is flush with the upper surface of the lower layer of the arc-shaped groove. A dial wheel is rotatably connected to the lower base near the locking mechanism. The dial wheel is meshed with the gear and is connected for transmission. The other side of the dial wheel is located on the outer side of the lower base.

[0008] Preferably, the outer sides of the left and right frames are arc-shaped, and the inner sides of the protruding parts on both sides of the lower base are arc-shaped, with the two arcs being consistent.

[0009] Preferably, the side of the upper base and the lower base opposite to the arc-shaped groove is also provided with an arc-shaped groove.

[0010] Preferably, one of the frames connected to the upper and lower frames has a handle fixedly connected to one side.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a fixed mechanism installed at the connection of two frames. By extending and retracting the telescopic device, the different frames are firmly fixed together. Unlike common fixing methods, this method is more concealed and aesthetically pleasing. In addition, rubber wheels are set inside the frame. When placing the glass inside the frame, it is only necessary to slide the glass in, which is more convenient. Moreover, the rubber wheels can cushion the glass and prevent damage.

[0013] 2. The door and window fixing base provided in this utility model is an assembly type. During installation, simply fix the lower base in the installation position, install the door and window frame into the lower base from the arc-shaped groove, and then fix the upper base and the lower base together with bolts.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1 to 10 As shown, an aluminum alloy door and window connection and fixing structure includes a door and window fixing base 1 and a door and window frame 2. The door and window frame 2 is composed of four frames 202 spliced ​​together, and the four frames 202 can be customized according to the required length. The frame 202 has a groove inside, and multiple horizontal shafts 2021 are fixedly connected within the groove in the direction of the opening. Rubber wheels 207 are rotatably connected to the horizontal shafts 2021. The rubber wheels 207 facilitate the movement of the glass 206 and also dampen the glass 206 placed on the rubber wheels 207, preventing damage from impacts. The glass 206 is placed inside the groove, abutting against the rubber wheels 207. Sealing strips 205 are fixedly connected to the contact parts of the glass 206 with the frame 202 on both sides to prevent hard contact between the glass 206 and the frame 202, thus preventing damage to the glass 206. Both ends of the frame 202 are provided with limiting holes 204. A fixing mechanism 208 is provided at the connection of every two frames 202. The fixing mechanism 208 includes an outer frame 2081, which is "L" shaped. Inside the outer frame 2081, cylinders 2084 are fixedly connected in both the horizontal and vertical directions. Limiting gears 2085 are rotatably connected to the cylinders 2084. Telescopic devices 2082 are meshed and driven on both sides of the limiting gears 2085. The telescopic device 2082 includes a telescopic block 2082A that is slidably connected to the outer frame 2081. A spring 2083 is fixedly connected to one side of the telescopic block 2082A. One end of the spring 2083 is fixedly connected to the inside of the outer frame 2081. Under normal circumstances, the spring 2083 is in a state of no force. When the telescopic block 2082A is pressed into the outer frame 2081, the spring 2083 is in a stretched state. The telescopic block 2082A has a meshing toothed plate 2082B on the side near the limiting gear 2085. The telescopic block 2082A and the limiting hole 204 are slidably connected. The toothed plate 2082B and the gear 2085 cooperate so that by pushing only one side of the telescopic block 2082A, the telescopic block 2082A on the other side can be extended and retracted synchronously through the limiting gear 2085, thereby locking and opening the frame 202.

[0028] A rotating wheel 201 is fixedly connected to the middle position of one side of the outer side of the two frames 202. For example... Figure 7 and Figure 8As shown, the door and window fixing base 1 includes an upper base 102 and a lower base 105. The upper base 102 has protrusions 103 fixedly connected to both ends on one side. The bottom side of the protrusions 103 has a threaded hole 109 that communicates with the upper base 102. The lower base 105 is U-shaped. The upper ends of the two protruding parts have grooves 104. The grooves have threaded holes 109 inside. The protrusions 103 and grooves 104 are slidably connected. The threaded holes 109 are threaded with bolts 101 that fix the upper base 102 and the lower base 105. The bottom inner side of the lower base 105 has an arc-shaped groove 106. The arc-shaped groove 106 has two layers. The diameter of the groove on the side of the upper layer near the frame is the same as the diameter of the rotating wheel 201, and the diameter on the other side is smaller than the diameter of the rotating wheel 201. The diameter of the lower layer is the same as the diameter of the rotating wheel 201. The advantage of this design is that when the rotating wheel 201 enters the lower layer of the arc-shaped groove 106, it will not slip out of the arc-shaped groove 106, which plays a limiting role.

[0029] The arc-shaped groove 106 is located near the middle side of the lower base 105, such as Figure 4 and Figure 5 As shown, a locking mechanism 107 is rotatably connected to the lower layer. The locking mechanism 107 includes a gear 1072 rotatably connected to the lower base 105. A semi-circular baffle 1071 is fixedly connected above the gear 1072. The semi-circular baffle 1071 is semi-circular, and one side of its interior abuts against the outer surface of the rotating wheel 201. The advantage of this design is that during normal use, the rotating wheel 201 is fixed only in the middle of the lower base 105, allowing the door and window frame 2 to be opened and closed arbitrarily. When a wider field of vision is needed or the door and window frame 2 needs to be installed or disassembled, the dial wheel 108 is rotated. The dial wheel 108 drives the gear 1072 to rotate, and the gear 1072 drives the semi-circular baffle 1071 to rotate, allowing the rotating wheel 201 to move left and right from its original restricted movement into the arc-shaped groove 106 of the rotating wheel 201. The upper surface of the gear 1072 is flush with the lower upper surface of the arc-shaped groove 106, mainly to ensure that it does not affect the movement of the rotating wheel 201 in the arc-shaped groove 106. A dial 108 is rotatably connected to the side of the lower base 105 near the locking mechanism 107. The dial 108 is meshed with the gear 1072 for transmission. The other side of the dial 108 is located on the outside of the lower base 105.

[0030] like Figure 9As shown, the outer sides of the two left and right frames 202 are arc-shaped, and the inner sides of the protruding parts on both sides of the lower base 105 are also arc-shaped, with both arcs being the same. This design allows the frames 202 to rotate within the lower base 105 without colliding with each other. The upper base 102 also has an arc-shaped groove 106 on the side opposite to the arc-shaped groove 106 of the lower base 105. This design allows for the fixing of the casters 201 on the frame 202, thus securing the frame 202 and preventing displacement during rotation. A handle 203 is fixedly connected to one side of one of the frames 202 that connects to the upper and lower frames 202, facilitating the opening and closing of the door and window frame 2.

[0031] Usage: First, locate the gears on the door / window frame. Press the telescopic blocks 2082A on both sides of the outer frame 2081 to slide one side of the outer frame 2081 into the frame 202. Then, slide the other side of the outer frame 2081 into the frame 202 in the same way. The telescopic blocks 2082A, pulled by the spring 2083, extend outwards and enter the limiting holes of the frame 202, completing the fixation. When the three-sided frame 202 is connected, slide the glass 206 into the frame 202. The rubber wheel 207 inside the frame 202 rotates, sliding the glass 206 inwards. After the glass 206 is in place, use the same method to fix the other frame 202 using the fixing mechanism 208. After fixing, install the sealing strip 205 at the contact position between the glass 206 and the frame 202 to provide cushioning and protect the glass 206.

[0032] After the door and window frame 2 is installed, place the door and window frame 2 on the lower base 105, so that the rotating wheel 201 slides from one side of the lower base 105 into the arc-shaped groove 106, and then install the upper base 102 on the lower base 105, and fix the upper base 102 and the lower base 105 with bolts 101.

[0033] Rotating the dial 108 causes the gear 1072 to rotate. The semi-circular baffle 1071 on the upper side of the gear 1072 can fix the rotating wheel 201 in the middle of the lower base 105, or it can move the rotating wheel 201 to one side of the door and window fixing base 1.

[0034] If the glass breaks, simply use a screwdriver to press against one side of the telescopic block 2082A. The other side's telescopic block 2082A will retract inward simultaneously due to the action of the intermediate limiting gear 2085. Remove one side of the frame 202, take out the broken glass 206, remove the sealing strip 205, reinstall the glass 206, and follow the installation steps described above.

[0035] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
