Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a door and window fork transmission balance mechanism, a door and window fork, and a door and window. Background Technology
[0002] Door and window levers are a common mechanism on aluminum alloy doors and windows. A lever connected to a handle on the door or window rotates, and the lever drives a slider to move back and forth, locking or unlocking the door or window. In existing technology, the slider connected to the lever is mostly a rectangular block. When the lever applies force to the slider, the slider exerts a force against the side wall of the door / window track profile, resulting in friction. This can easily lead to increased sliding resistance, uneven sliding, and friction noise. Utility Model Content

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Reference Figures 1-7 As shown, a door and window fork transmission balancing mechanism includes a slider body 2 connected to a door and window fork 1, with rollers 3 installed at the four corners of the slider body 2; the slider body 2 slides in contact with the side wall of the door and window track profile 4 through the rollers 3. This can effectively reduce the frictional resistance and noise when the slider body 2 slides.
[0029] In this embodiment, the slider body 2 preferably includes a first roller mounting part 2-1, a second roller mounting part 2-2, and a transition connection part 2-3. The transition connection part 2-3 is connected between the first roller mounting part 2-1 and the second roller mounting part 2-2 and protrudes outward. Corresponding roller mounting grooves 2-4 with external openings are respectively provided on the connecting side of the transition connection part between the first roller mounting part 2-1 and the second roller mounting part 2-2. Corresponding roller mounting posts 2-5 for forming roller shafts are provided on each roller mounting groove 2-4.
[0030] The advantages of this design are: 1) It facilitates the formation of a fork mounting part 2-6 between the first roller mounting part 2-1 and the second roller mounting part 2-2, which is beneficial for the connection of door and window forks; 2) It facilitates the connection of the transmission intermediate part 5 at the transition connection part 2-3, thereby realizing the linkage of other transmission components; 3) The slider body 2 will form a semi-enclosed protection for the roller 3, reducing the occurrence of failures such as roller jamming and extending the service life of the roller 3.
[0031] Obviously, those skilled in the art can appropriately change the shape of the slider body 2 according to different actual needs, as long as it can install rollers to form sliding contact and connect transmission intermediate parts.
[0032] In this embodiment, the slider body 2 is preferably made of stainless steel, and the roller is preferably made of plastic, which provides the best application effect. In some embodiments, the plastic slider body can be made of metal such as aluminum alloy or copper alloy, and the roller can be made of rubber; however, this is not limited to this embodiment.
[0033] In this embodiment, preferably, the transition connection 2-3 is provided with a screw hole 2-7 for connecting the transmission intermediate component 5, and the transmission intermediate component 5 is provided with a through hole 5-1 corresponding to the screw hole 2-7. A bolt 6 passes through the through hole 5-1 to fix the transmission intermediate component 5 to the slider body 2; this facilitates the connection and disassembly of the transmission intermediate component 5 and the slider body 2.
[0034] In this embodiment, it is preferable that the depth of the roller mounting groove 2-4 is greater than the thickness of the roller 3. In this way, after the roller 3 is installed on the roller mounting groove 2-4, it only protrudes from the outer opening, which effectively reduces the contact between the roller 3 and other components, thereby better reducing frictional resistance and operating noise.
[0035] Combined Figures 4-7 As shown, the door and window track profile 4 has two tracks, upper and lower, which are connected by a notch 4-1. The transmission intermediate component 5 and the slider body 2 are respectively set in two different tracks, and the transition connection part 2-3 is set through the notch 4-1.
[0036] Figure 7 The image shows the state of the door and window pull fork 1 being pushed downwards. At this time, rollers C and D will exert a lateral force on the side wall of the door and window track profile 4, while the other two rollers will not exert a lateral force. The sliding contact area is small, and the sliding resistance and noise are low.
[0037] It should also be noted that in the description of this utility model, directional terms such as "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.
[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in this description of the utility model, "at least" means one or more, unless otherwise explicitly specified.
[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0040] In this utility model, unless otherwise specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "below," and "over" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Above," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
