Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a reinforced aluminum alloy door and window. Background Art

[0002] The aluminum alloy doors and windows on the market have guide rails inside the window slots, and the movable windows slide on the guide rails to open and close the windows. Therefore, when removing the movable windows, the user needs to lift the movable windows upwards and tilt them to remove them, which is laborious. At the same time, in order to tilt the movable windows, the slots where the movable windows are stuck in the movable rails need to be wider than the width of the slots. When strong winds blow, the movable windows will shake, resulting in the movable windows being not strong enough.

[0003] The utility model with the publication number CN219638685U proposes a reinforced aluminum alloy door and window, including a bottom frame and a side frame, the bottom frame and the side frame are vertically connected to each other, a fixed guide rail is fixedly connected above the bottom frame, a movable guide rail is vertically slidably connected to one side of the fixed guide rail on the bottom frame, and a movable window is placed on the fixed guide rail and the movable guide rail; a spring is connected between the bottom end of the bottom frame and the movable guide rail, a rotating rod is rotatably connected below the movable guide rail inside the bottom frame, a sprocket is fixedly connected to one end of the rotating rod, a cam is fixedly connected to both sides of the movable guide rail on the rotating rod, a limiting rod is fixedly connected to one side of the cam, and one end of the limiting rod is located above both sides of the movable guide rail. By designing the movable guide rail, the movable window can be moved forward and backward by retracting the movable guide rail into the upper and lower bottom frames, which is convenient for users to remove the movable window, and at the same time avoids the need for tilting the movable window, so that the slot below the movable window is more in line with the guide rail, avoiding the shaking of the movable window, and being more solid.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The structure for driving the cam to rotate is hidden in the side frame. Due to the small space of the side frame and the large resistance to driving the movable guide rail to move downward, the driving method of the rack and gear meshing is used to transmit power to the chain drive, and then it is difficult to generate a large driving force in the structure that drives the cam to rotate, which leads to the defect that the operation of removing the restriction on the movable window is relatively laborious and inconvenient; 2. After the movable guide rail is lowered, the movable window is removed by pulling the movable window in the direction of the descending movable guide rail. However, since the movable window is heavy, force needs to be applied to keep the movable window when manually pulling it upward to the descending movable guide rail to prevent it from tilting and affecting the smoothness of movement. In addition, the auxiliary movable window needs to be aligned with one end of the fixed guide rail during installation, so there is a defect that the disassembly and assembly of the movable window is labor-intensive.

[0005] To this end, the utility model provides a reinforced aluminum alloy door and window. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1 to 7 The utility model provides a technical solution: a reinforced aluminum alloy door and window, comprising a rectangular window frame 1, two movable windows 101, and an upper guide rail 2 and a lower guide rail 3 located in the rectangular window frame 1. The top and bottom of the movable window 101 are provided with grooves 1011 respectively rolling or sliding with the upper guide rail 2 and the lower guide rail 3. The two movable windows 101 are staggered, and the opening and closing of the windows can be controlled by pushing and pulling the movable windows 101.

[0026] In the present technical solution, a groove 11 is provided at the bottom of the rectangular window frame 1, and a supporting plate 4 is slidably connected to the groove 11 up and down. The length and width of the supporting plate 4 are approximately equal to the length and width of the groove 11. The lower guide rail 3 is fixedly arranged on the top of the supporting plate 4. When the supporting plate 4 moves up and down, the distance between the upper guide rail 2 and the lower guide rail 3 can be changed. When the distance between the upper guide rail 2 and the lower guide rail 3 increases, the groove 1011 at the top of the movable window 101 will be separated from the upper guide rail 2, and the movable window 101 can be easily removed at this time.

[0027] There are two rotating shafts 5 rotatably connected between the front and rear side walls in the sink 11, and in specific implementation, it is preferred that the limiting sleeves rotatably connected to the rotating shafts 5 can be welded on both sides of the sink 11. An eccentric disk 6 is fixedly provided on the rotating shaft 5, and the outer peripheral wall of the eccentric disk 6 is against the bottom of the bearing plate 4. When the eccentric disk 6 rotates, it can drive the bearing plate 4 to rise by its eccentric characteristics, and the bearing plate 4 descends by its own weight to maintain the state of being against the eccentric disk 6. One end of the rotating shaft 5 extends to the outside of the rectangular window frame 1 and is fixedly connected with an arm 7. When the bearing plate 4 is at the highest point, the arm 7 on the two rotating shafts 5 is in line, and the arm 7 acts as a force arm, thereby reducing the driving force required for manually swinging the arm 7. This arrangement makes the lifting and lowering control of the bearing plate 4 that supports the movable window 101 more labor-saving and convenient.

[0028] Furthermore, one end of the arm 7 is fixedly connected to one end of the rotating shaft 5. When the supporting plate 4 is at the highest point, the free ends of the arms 7 on the two rotating shafts 5 are opposite to each other. Therefore, by manually holding the two arms 7 and swinging them upward at the same time, the supporting plate 4 can be controlled to descend, and by controlling the two arms 7 to swing downward at the same time, the supporting plate 4 will rise.

[0029] In this embodiment, the front sides of the arms 7 on the two rotating shafts 5 are rotatably connected via an elastic telescopic rod 8. The arrangement of the elastic telescopic rod 8 has the function of preventing the arms 7 from accidentally rotating. That is to say, due to the elastic traction of the movable elastic telescopic rod 8, the impact arm 7 will not rotate accidentally. Moreover, when the impact arm 7 rotates accidentally, the impact force of the large swing generated by the arm 7 can be effectively buffered. This impact force is provided by the weight of the movable window 101.

[0030] Furthermore, the elastic telescopic rod 8 includes a connecting tube 81, a tension spring 82 and a pull rod 83, one end of the pull rod 83 is sleeved on one end of the connecting tube 81 and is slidably matched, the tension spring 82 is sleeved in the connecting tube 81 and its two ends are respectively fixedly connected to the bottom of the connecting tube 81 and one end of the pull rod 83, the front side of the arm 7 is welded with a connecting shaft 71 close to the rotating shaft 5, and one end of the connecting tube 81 and the pull rod 83 are both provided with a connecting hole 9 that can be detachably matched with the connecting shaft 71, and the connecting shaft 71 is a T-shaped structure. Since the connecting shaft 71 is close to the rotating shaft 5, the elastic telescopic rod 8 can be easily extended by manually swinging the arm 7, without affecting the labor-saving rotation control of the eccentric disk 6. Moreover, the detachable setting of the elastic telescopic rod 8 relative to the arm 7 facilitates the reset installation of the movable window 101.

[0031] In this embodiment, an upper baffle 102 is fixedly connected to the top of the rectangular window frame 1, and an upper guide rail 2 is fixedly arranged on the lower end surface of the upper baffle 102. The bottom of the upper baffle 102 is fixedly connected to a protective plate 1021 located on the outside of the movable window 101. The outside here refers to the side of the movable window 101 facing the outdoors, that is, the protective plate 1021 is located outdoors. This arrangement ensures that when the top of the movable window 101 detaches from the upper guide rail 2, it will be blocked by the protective plate 1021 to prevent it from tilting outward and falling. The two ends of the protective plate 1021 are respectively fixedly connected to the two sides inside the rectangular window frame 1. This arrangement can improve the positioning strength of the protective plate 1021 and improve the strength of the entire rectangular window frame 1. One side of the upper baffle 102 is fixedly connected with a block 1022 close to one end and located on the inner side of the movable window 101. The function of this block 1022 is to prevent the movable window 101 that has separated from the upper guide rail 2 from tilting inward and falling. Since the block 1022 is arranged close to one end of the upper baffle 102, the movable window 101 can be manually pushed to bypass the block 1022, and then the movable window 101 can be smoothly disassembled.

[0032] In this embodiment, at least two guide shafts 41 are welded to the bottom of the bearing plate 4, a guide sleeve 111 which is sleeved on the outside of the guide shaft 41 is welded to the bottom of the sink 11, and a reinforcing plate 42 close to the front and rear sides is fixedly connected to the bottom of the bearing plate 4. The function of the reinforcing plate 42 is to improve the strength of the bearing plate 4 against bending deformation, and under the guiding cooperation of the guide sleeve 111 and the guide shaft 41, the strength of the bearing plate 4 supporting the movable window 101 is greatly improved.

[0033] Working principle: when the movable window 101 needs to be disassembled, hold the two arm bars 7 and swing them up at the same time, the elastic telescopic rod 8 extends, the tension spring 82 stretches, the two rotating shafts 5 rotate in opposite directions to drive their respective eccentric disks 6 to rotate, the carrying plate 4 and the two movable windows 101 thereon descend, the groove 1011 at the top of the movable window 101 disengages from the upper guide rail 2, and then manually push the movable window 101 to bypass the block 1022, and the movable window 101 can be easily removed.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
