Description

Technical Field

[0001] The utility model relates to the field of door and window corner turners, in particular to a door and window corner turner. Background Art

[0002] Corner turners are one of the commonly used hardware accessories for doors and windows. They are usually installed at the corners of window sashes and are used to connect other hardware on the two sides of the window sashes to achieve the linkage of the door and window hardware system. However, the existing corner turners still have some shortcomings. Specifically, Figure 6 As shown, it is the general structure of the angle turner in the prior art, which usually includes two fixed connecting parts and a flexible sheet body connecting the two fixed connecting parts. The two fixed connecting parts are correspondingly installed to connect the transmission rods in two directions in the door and window profiles. The angle turner of this structure has the disadvantage that the flexible sheet body will gradually deform during long-term use, thereby affecting the use effect and even failing. At the same time, the angle turner of this structure will also have transmission deviation (usually 2-3 mm) during the transmission process, which increases the difficulty of the designer's design work; in addition, the transmission smoothness of the transmission device of this structure is not so good.

[0003] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0032] Refer to the attached Figures 1 to 6 In the embodiment of the utility model, a door and window angler includes an angler body 10, a transmission assembly 20, a first connecting member 31, and a second connecting member 32.

In actual application, the first connecting member 31 and the second connecting member 32 are connected to the first transmission rod and the second transmission rod respectively.

[0034] Preferably, the rotating plate 21 is an isosceles triangle (in some embodiments, it can also be an equilateral triangle), the third rotating shaft 213 is set corresponding to the vertex angle of the isosceles triangle, and the first rotating shaft 211 and the second rotating shaft 212 are set corresponding to the two base angles of the isosceles triangle. Figure 5When the second connecting member 32 is pulled downward, the rotating plate 21 rotates counterclockwise around the third rotating shaft 213, and then the rotating plate 21 pulls the first transmission chain 22 (and the first connecting member 31) to move leftward, thereby realizing the transmission function of the transmission assembly 20. When the first connecting member 31 moves leftward, the rotating plate 21 rotates clockwise around the third rotating shaft 213, and then the rotating plate 21 pulls the second transmission chain 23 (and the second connecting member 32) to move upward, thereby realizing transmission. It should be supplemented that during the transmission process, relative rotation occurs between the first transmission chain 22 and the first connecting member 31, and therefore, a first avoidance groove 111 is correspondingly provided on the lateral side 11 of the corner turner body 10, and relative rotation occurs between the second transmission chain 23 and the second connecting member 32, and therefore, a second avoidance groove 121 is correspondingly provided on the vertical side 12 of the corner turner body 10.

[0035] Specifically, the angle turner body 10 includes a horizontal side 11 and a vertical side 12 that are connected to each other, and the horizontal side 11 and the vertical side 12 are perpendicular to each other.
