[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the corner adjustment device for metal doors and windows provided by this utility model; Figure 2 for Figure 1 The side sectional view shown is shown below; Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The diagram shows the internal explosion structure. Figure 5 for Figure 4 The enlarged schematic diagram of section B is shown below; Figure 6 for Figure 4 The enlarged schematic diagram of section C is shown. The angle adjustment device for metal doors and windows includes: a rotating body 1, a connecting sleeve 11, and an angle adjustment carrier 12. The connecting sleeve 11 for rotating the angle is installed outside the rotating body 1, and the angle adjustment carrier 12 is installed outside the connecting sleeve 11. The angle adjustment carrier 12 is internally provided with an adjustment component 2 for adapting to different metal door and window sizes. The adjustment component 2 is externally provided with a locking component 3 for installing metal doors and windows, and the locking component 3 is externally provided with a protective component 4.

[0023] The adjustment assembly 2 includes a displacement groove 21 and a symmetrical motion transmission shaft 22. The displacement groove 21 is disposed outside the angle adjustment carrier 12, and the symmetrical motion transmission shaft 22 is disposed inside the displacement groove 21. The symmetrical motion transmission shaft 22 passes through the angle adjustment carrier 12 and extends to its outside. Both ends of the symmetrical motion transmission shaft 22 are provided with cross rotating blocks 23. The displacement groove 21 is slidably connected to a first movable clamping member 24 and a second movable clamping member 25, which are used to adjust the size by relative movement through cooperation with the symmetrical motion transmission shaft 22. The first movable clamping member 24 and the second movable clamping member 25 are both threadedly connected to the symmetrical motion transmission shaft 22. In addition, the exterior of the first movable clamping member 24 and the second movable clamping member 25 are provided with four symmetrically distributed threaded holes 26.

[0024] The adjusting component 2 plays a crucial role in the dimensional adaptation of the metal door and window angle adjustment device. The displacement groove 21, located outside the angle adjustment carrier 12, provides stable installation and movement space for other components. The symmetrical motion transmission shaft 22, located inside the displacement groove 21 and extending through the angle adjustment carrier 12 to the outside, has cross-shaped rotating blocks 23 at both ends for easy application of rotational force by the user. The first movable clamping member 24 and the second movable clamping member 25 are slidably connected within the displacement groove 21 and threadedly connected to the symmetrical motion transmission shaft 22. When the cross-shaped rotating blocks 23 are rotated, causing the symmetrical motion transmission shaft 22 to rotate, these two clamping members can move relative to each other, thereby adjusting the overall size of the device to accommodate the size requirements of different metal doors and windows. The four symmetrically distributed threaded holes 26 on the outside of the first movable clamping member 24 and the second movable clamping member 25 serve as the foundation for subsequent installation of metal doors and windows, facilitating the stable fixing and adjustment of the metal doors and windows by the device.

[0025] Among them, the symmetrical motion transmission shaft 22 includes, but is not limited to, a two-way lead screw, a rack and pinion transmission mechanism, and a synchronous belt transmission assembly;

[0026] In this embodiment, the symmetrical motion transmission shaft 22 is preferably a bidirectional lead screw. It has advantages such as high transmission accuracy, strong load-bearing capacity, and compact structure, and can accurately realize the symmetrical movement of the first moving clamping member 24 and the second moving clamping member 25, thereby meeting the requirements of the adjustment assembly 2 for dimensional adjustment accuracy and stability.

[0027] The locking component 3 includes a transmission component 31 and a rotating component 32. A positioning component 33 for preventing disengagement during rotation is fixedly connected to the front of the second movable clamping component 25. A rotating shaft 34 is movably connected inside the positioning component 33. The inside of the transmission component 31 is fixedly connected to the outside of the rotating shaft 34. The rotating shaft 34 passes through the transmission component 31 and extends to its outside. A turning block 35 is fixedly connected to the end of the rotating shaft 34. A stud 36 for fixing metal doors and windows is threaded inside the threaded hole 26. The stud 36 passes through the threaded hole 26 and extends to its outside. The rotating component 32 is installed at the end of the stud 36. The outer surface of the rotating component 32 engages with the outer surface of the transmission component 31. A limiting ring 37 is fixedly connected to the outer surface of the stud 36. A circular protrusion 38 is provided between the limiting ring 37 and the rotating component 32. The inside of the circular protrusion 38 is movably connected to the outer surface of the stud 36.

[0028] The locking component 3 plays a crucial role in the stable fixation during the installation of metal doors and windows. The positioning component 33 is fixed to the front of the second movable clamping component 25, effectively preventing the rotating shaft 34 from disengaging during rotation and laying a solid foundation for the stable operation of subsequent components. The rotating shaft 34 is movably connected to the positioning component 33, its exterior is fixed to the transmission component 31, and its end is connected to the turning block 35. The user can rotate the turning block 35 to drive the rotating shaft 34 and the transmission component 31 to rotate synchronously. The stud 36 is fixed by engaging with the threaded hole 26 through the thread, and is screwed into the reserved installation hole of the metal door and window. The rotating component 32 installed at its end meshes with the outer surface of the transmission component 31. When the transmission component 31 rotates in the forward or reverse direction, it drives the rotating component 32 to rotate in the opposite direction through the meshing action, realizing the axial movement of the stud 36 and completing the locking or unlocking operation of the metal door and window. The limiting ring 37 is fixed on the outer surface of the stud 36, and the circular protrusion 38 between it and the rotating part 32 restricts the axial position of the rotating part 32 and prevents it from moving excessively along the axial direction of the stud 36. On the other hand, the circular protrusion 38 can rotate flexibly around the stud 36 with the rotating part 32, ensuring that the entire locking process is smooth and stable, and ensuring the firmness and reliability of the metal door and window installation.

[0029] The transmission component 31 and the rotating component 32 include, but are not limited to, gear transmission, worm gear transmission, and belt transmission.

[0030] In this embodiment, the transmission component 31 and the rotating component 32 are preferably of the gear transmission type. This is because, in this metal door and window locking scenario, high transmission accuracy and efficiency are required to ensure that the stud 36 can accurately achieve axial movement, thereby reliably fixing the metal door and window.

[0031] The protective component 4 includes a protective cover 41 and a protective cap 42. The protective cover 41 is installed on the front of the second movable clamping component 25. The inner wall of the protective cover 41 is provided with four symmetrically distributed guide structures 43. The interior of the guide structure 43 is slidably connected to the exterior of the circular protrusion 38. The rotating shaft 34 passes through the protective cap 42 and extends to its exterior.

[0032] The protective component 4 provides comprehensive protection for the metal door and window corner adjustment device, greatly extending its service life. The protective cover 41, installed on the front of the second movable clamping component 25, effectively blocks dust, debris, and moisture, preventing them from entering the locking component 3 and preventing wear and malfunction due to foreign object intrusion. Four symmetrically distributed guide structures 43 on the inner wall of the protective cover 41 are slidably connected to the outside of the circular convex plate 38. These not only guide the smooth movement of the circular convex plate 38 and maintain the stable operation of the rotating component 32 and the stud 36, but also provide positioning and support for the protective cover 41, improving the overall structural stability. The protective cover 42 protects the rotating shaft 34 from direct exposure to impact or corrosion. The rotating shaft 34 passes through the protective cover 42 and extends to the outside, ensuring normal rotation of the rotating shaft 34 while allowing operators to easily operate the turning block 35 to lock or unlock the metal door and window.

[0033] Among them, the guide structure 43 includes, but is not limited to, guide rail type, slide type, and ball type;

[0034] In this embodiment, the guide structure 43 is preferably a chute type, which is relatively simple to design and manufacture, can effectively reduce production costs and manufacturing difficulty, and meets the needs of large-scale production. Furthermore, the outer side of the circular convex plate 38 has protrusions that are adapted to the chute, and the protrusions slide within the chute to achieve guidance.

[0035] An auxiliary component 5 is provided on the outside of the rotating body 1. The auxiliary component 5 includes an elastic seal 51 and a mounting connector 52. The elastic seal 51 is installed on the outside of the rotating body 1. The inside of the mounting connector 52 is movably connected to the outside of the rotating body 1. A concave ring block 53 for assisting rotation is provided on the outside of the rotating body 1. A circular block 54 is slidably connected inside the concave ring block 53. A threaded groove 55 for adding lubricating grease is provided on the outside of the rotating body 1.

[0036] The auxiliary component 5 provides comprehensive assistance and protection for the rotating body 1, greatly improving the performance of the metal door and window corner adjustment device. The elastic seal 51, installed on the outside of the rotating body 1, effectively blocks the intrusion of dust, moisture, and other impurities, preventing internal components from being damaged by corrosion or wear, while also preventing internal lubricant leakage, ensuring the stable operation of the rotating body 1. The mounting connector 52 is movably connected to the outside of the rotating body 1, facilitating the installation of the rotating body 1 with other parts of the device. The concave ring block 53 and the circular block 54 on the outside of the rotating body 1 slide together, effectively reducing friction during rotation and helping the rotating body 1 rotate easily and smoothly, making the corner adjustment process of the metal door and window smoother. The threaded groove 55 facilitates the periodic addition of lubricant, further reducing wear between components, extending the service life of the rotating body 1, and ensuring the long-term stable operation of the entire metal door and window corner adjustment device.

[0037] Among them, the elastic sealing element 51 includes, but is not limited to, O-rings, lip seals, and rubber gaskets;

[0038] In this embodiment, the elastic seal 51 is preferably an O-ring. In the application scenario of the rotating body 1, the seal needs to be able to adapt to the dynamic changes during rotation and achieve a reliable seal in a small space. The O-ring has the characteristics of simple structure and easy installation, and can provide a good sealing effect in a limited space.

[0039] The angle adjustment carrier 12 is provided with a storage component 6 on its exterior. The storage component 6 includes a receiving component 61 and a dustproof component 62. The receiving component 61 is disposed on the exterior of the angle adjustment carrier 12. The dustproof component 62 is slidably connected to the receiving component 61. A hand push-pull component 63 is fixedly connected to the exterior of the dustproof component 62.

[0040] The storage component 6, located outside the angle adjustment carrier 12, provides convenient storage and protection for the metal door and window angle adjustment device. The receiving component 61 provides dedicated storage space for adjustment tools, spare parts, etc., preventing loss and allowing easy access to necessary items during use, thus improving work efficiency. The dustproof component 62 is slidably connected to the receiving component 61, effectively preventing dust and impurities from entering the receiving component 61 when the storage space is not in use, avoiding dust accumulation that could affect normal use and extending the lifespan of stored items. The hand-operated push-pull component 63 is fixed to the outside of the dustproof component 62, greatly facilitating user operation. By pushing and pulling the hand-operated push-pull component 63, the dustproof component 62 can be easily slid, opening and closing the storage component 6. Operation is simple and convenient.

[0041] The hand-operated push-pull component 63 includes, but is not limited to, a handle, a pull ring, and a grinding block;

[0042] In this embodiment, the hand-pushing component 63 is preferably an abrasive block. It has a large coefficient of friction, which ensures sufficient friction when pushing and pulling the dustproof component 62 even if the hands are not dry or have a small amount of dirt, thus preventing hand slippage and ensuring the reliability of operation.

[0043] The working principle of the metal door and window angle adjustment device provided by this utility model is as follows: First, when the user operates the metal door and window, the connecting sleeve 11 and the rotating body 1 cooperate to change their relative positions, achieving flexible angle adjustment of the door and window. At the same time, the angle adjustment carrier 12 provides stable support for the installation of subsequent parts. Then, according to the size of different metal doors and windows, the adjustment component 2 adjusts its own structure inside the angle adjustment carrier 12 to adapt to the door and window. Next, the locking component 3 is used to fix the door and window firmly in a simple and efficient way, replacing the operation of tightening multiple nuts and bolts. Finally, during the use of the metal door and window, the protective component 4 is attached to the outside of the locking component 3 to prevent dust and impurities from entering the device, reducing wear on various components, thereby extending the service life of the device and ensuring stable and safe angle adjustment of the door and window.
