Technical Field

[0001] The utility model relates to the technical field of door and window anglers, in particular to an angle-adjustable door and window angler. Background Art

[0002] Door and window corner connectors are commonly found at the diagonal corners of doors and windows, especially when the diagonal angle of the doors and windows is not 90 degrees. This connector helps to connect the profiles on the two sides together to ensure smooth movement of the doors and windows during opening and closing.

[0003] After searching, it is found that a Chinese patent document discloses an angle-adjustable door and window angle device [application number: CN202222936992.1]. This angle-adjustable door and window angle device includes a transmission rod, a flexible transmission member, a first connection member and a second connection member respectively connected to two adjacent sides of the window sash, the first connection member and the second connection member are pivotally connected to each other; the transmission rod and the second connection member are slidably matched, the flexible transmission member is slidably matched with the first connection member and the second connection member at the same time, and one end of the flexible transmission member is fixedly connected to the transmission rod.

[0004] When the device disclosed in the patent is in use, since the first connecting member and the second connecting member are connected in a hinged manner, the angle between the first connecting member and the second connecting member can be freely adjusted to adapt to different angles. At the same time, the flexible transmission member itself is flexible and can be bent arbitrarily to adapt to the angle between the first connecting member and the second connecting member. However, when the device is in use, when it is necessary to adjust the angle between the first connecting member and the second connecting member, it is necessary to contact external tools for adjustment, which leads to a decrease in the adjustment efficiency of the device, increases the adjustment time of the staff, reduces the subsequent installation efficiency of doors and windows, and has low practicality and convenience. In view of this, we propose an angle-adjustable door and window angler to solve the above problems. Utility Model Content

The device can achieve adjustment without the staff carrying tools, saves the staff's adjustment time and operation steps, and avoids the situation of forgetting to bring tools. It is highly practical and flexible.

[0024] Furthermore, the driving assembly includes a telescopic base 13, the telescopic base 13 is fixedly connected to the first connecting rod 11, a groove 12 is provided on the right side surface of the first connecting member 1, the telescopic base 13 and the left side surface and the inner wall of the groove 12 are rotatably connected, a sliding groove 15 is provided inside the telescopic base 13, a sliding rod 14 is slidably connected inside the sliding groove 15, the sliding rod 14 extends out of the telescopic base 13, a second cavity 16 is provided inside the telescopic base 13, the second cavity 16 is communicated with the sliding groove 15, the sliding rod 14 extends into the second cavity 16, a rotating disk 19 is rotatably connected to the bottom wall of the second cavity 16, a spring 20 is fixedly connected between the rotating disk 19 and the sliding rod 14, four card slots 17 are provided on the inner wall of the sliding groove 15, and the outer surface of the sliding rod 14 at one end of the second cavity 16 is fixedly connected There are four blocks 18 connected, and the blocks 18 and the slots 17 are adapted to each other. A protective component is arranged inside the sliding rod 14. When the staff needs to drive the first connecting rod 11 to rotate, the sliding rod 14 is first pulled outward. At this time, the sliding rod 14 will slide inside the second cavity 16 and the sliding slot 15, and the spring 20 will be stretched. Subsequently, the sliding rod 14 is slowly rotated. The rotation of the sliding rod 14 will drive the spring 20 and the rotating disk 19 to rotate synchronously. The sliding rod 14 is rotated while the sliding rod 14 is slowly rotated. When the block 18 and the slot 17 are aligned, the block 18 can slide into the slot 17. Then, the rotation of the telescopic base 13 can be driven by rotating the sliding rod 14. The rotation of the first connecting rod 11 is driven by the rotation of the telescopic base 13, and finally the rotation of the first connecting member 1 and the second connecting member 2 is realized.

When the staff needs to drive the sliding rod 14 to rotate, the driving handle 25 is first rotated out of the groove 12. At this time, the driving handle 25 will bring The movable connecting plate 22 rotates with the second connecting rod 21 as the axis, thereby driving the rotation of the second connecting rod 21. At this time, the torsion spring 24 will be stretched, so that the driving handle 25 is located outside the groove 12. The staff can subsequently shake the driving handle 25 to realize the initiative of the sliding rod 14. When the staff drives to store the driving handle 25, the driving handle 25 is turned to be on the same axis as the sliding rod 14.
