[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides an aluminum alloy door and window multi-locking point structure, including an outer fixed frame 1 and an inner movable frame 2 movably hinged to the inner side of the outer fixed frame 1, two installation openings 3 are arranged on the upper and lower right sides of the outer side of the inner movable frame 2, a turning handle 4 is rotatably installed on the inner side of the inner movable frame 2, locking members 5 are movably installed inside the two installation openings 3, and a fixing cover 6 corresponding to the installation opening 3 is fixedly installed on the outer side of the inner movable frame 2.

[0024] By setting the installation opening 3 inside the inner movable frame 2 and installing the locking member 5 inside the installation opening 3, the installation opening 3 is closed from the inner side of the inner movable frame 2 using the fixed cover 6, and the locking member 5 is slid inward and outward so that the locking member 5 passes through the inner movable frame 2 and is fixed inside the outer fixed frame 1, and the inner movable frame 2 and the outer fixed frame 1 are locked from the upper and lower sides in cooperation with the turning handle 4, and the safety is improved by increasing the locking points. The locking member 5 is separately arranged, and during installation, the locking member 5 is installed in the installation opening 3 for connection, and the installation opening 3 is closed by the fixed cover 6, so that the installation is simple and easy to use.

[0025] like Figures 2 to 5 As shown, the mounting opening 3 includes a sliding groove 31, a locking opening 1 32 is provided on one side of the sliding groove 31 close to the outer fixed frame 1, a limiting groove 33 connected to the sliding groove 31 is provided inside the fixed cover 6, a locking opening 2 34 is provided on the top of the sliding groove 31, an inner groove 35 is provided on the outer side of the sliding groove 31, and a limiting edge strip 36 is fixedly connected inside the sliding groove 31.

[0026] The locking member 5 includes a slider 51, a side of the slider 51 close to the block 52 is fixedly connected to the block 52, the inner side of the slider 51 is fixedly connected to a protrusion 53, the outer side of the protrusion 53 is bolted to a push plate 54, the slider 51 is provided with a movable groove 55, the movable groove 55 is movably connected to a support plate 56, the top of the support plate 56 is fixedly connected to a column 57, and the outer side of the column 57 is movably sleeved with a support spring 58.

[0027] By pushing the push plate 54 from the inner side of the inner movable frame 2 toward the direction of the turning handle 4, the push plate 54 drives the connected protrusion 53 to slide outward along the limiting groove 33, thereby driving the slider 51 located inside the sliding groove 31 to drive the card block 52 to slide outward, so that the card block 52 passes through the locking opening 1 32 and is fixed in the inner part of the outer fixed frame 1. At the same time, as the slider 51 moves, the support plate 56 on the inner side of the movable groove 55 is forced to slide upward along the movable groove 55, and the support spring 58 is compressed by the support plate 56 sliding up to lift the card column 57, so that the card column 57 passes through the locking opening 2 34 and is fixed on the upper and lower sides of the outer fixed frame 1, thereby locking the inner movable frame 2 from the upper and lower sides, increasing the locking points to cooperate with the turning handle 4 to improve safety.

[0028] like Figure 4 As shown, the slider 51 is movably engaged with the inner lower part of the sliding groove 31 , the block 52 is matched with the locking opening 32 , the protrusion 53 is movably engaged with the limiting groove 33 , and the push plate 54 is located on the outer side of the fixed cover 6 .

[0029] By sliding the push plate 54 located outside the fixed cover 6 and connecting with the protrusion 53 , the slider 51 can be driven to slide along the inside of the sliding groove 31 , so as to facilitate the adjustment of the locking state.

[0030] like Figure 4 As shown, the clamping column 57 is movably clamped in the interior of the second locking opening 34 , and the supporting spring 58 is movably clamped between the supporting plate 56 and the inner movable frame 2 .

[0031] The inner movable frame 2 can be locked from both the upper and lower sides by the support spring 58 located between the support spring 58 and the inner movable frame 2 in cooperation with the clamping column 57 in the second locking opening 34, thereby improving safety.

[0032] like Figure 2 As shown, the clamping column 57 and the support plate 56 are connected by threads, and a hexagonal hole is provided on the side of the clamping column 57 away from the support plate 56.

[0033] The clamping column 57 can be connected to the support plate 56 by rotating the clamping column 57 with a hexagonal wrench through the hexagonal hole provided on the outer side of the clamping column 57, so as to facilitate installation and use.

[0034] like Figure 5As shown, a damper is arranged between the slider 51 and the sliding groove 31, and the movable groove 55 and the supporting plate 56 are arranged in an inclined surface.

[0035] By setting a damping between the slider 51 and the sliding groove 31, when the slider 51 slides, the support plate 56 slides up and down along the movable groove 55 to squeeze the support spring 58 to control the locking state of the card column 57. By setting the damping force to be greater than the elastic force of the support spring 58, it is prevented that the support spring 58 pushes the support plate 56 located in the movable groove 55 to cause the slider 51 to move inward, thereby ensuring the stability of the locking.

[0036] like Figure 5 As shown, locking grooves corresponding to the clamping blocks 52 and the clamping columns 57 are arranged inside the outer fixing frame 1 .

[0037] The inner movable frame 2 is locked from both the upper and lower sides by means of locking grooves corresponding to the clamping blocks 52 and the clamping columns 57 provided in the outer fixed frame 1, thereby improving stability.

[0038] The following is a detailed description of the working principle of the multi-locking point structure of aluminum alloy doors and windows.

[0039] like Figures 1 to 5 As shown, the inner movable frame 2 is rotated inwardly along the outer fixed frame 1 and the inner movable frame 2 is fixed to the inner side of the outer fixed frame 1 by rotating the turning handle 4, and then the push plate 54 is pushed from the inner side of the inner movable frame 2 toward the turning handle 4, and the connected protrusion 53 is driven by the push plate 54 to slide outward along the limiting groove 33, thereby driving the slider 51 located inside the sliding groove 31 to drive the block 52 to slide outward, so that the block 52 passes through the locking opening 32 and is fixed inside the outer fixed frame 1, and at the same time, as the slider 51 moves, the support plate 56 inside the movable groove 55 is forced to move along the movable groove 55 to the inner side of the outer fixed frame 1. The support plate 56 slides upward to compress the support spring 58 so that the clamping column 57 is lifted up, so that the clamping column 57 passes through the locking opening 34 and is fixed to the upper and lower sides of the outer fixed frame 1. A damping force greater than the elastic force of the support spring 58 is set between the slider 51 and the sliding groove 31 to prevent the support spring 58 from releasing and causing the support plate 56 to push the slider 51 inward along the movable groove 55. The inner movable frame 2 is locked from the middle of the turning handle 4, and the clamping block 52 is used to cooperate with the clamping column 57 to lock from the upper and lower sides close to the side of the outer fixed frame 1 to reinforce the locking of the turning handle 4 and ensure safety.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
