Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a corner guide structure and door / window. Background Technology

[0002] The outer wall of the window sash is connected to various movable hardware components, such as transmission housings, locking rods, and tilting lock pins. These movable hardware components are connected by transmission rods.

[0003] In existing technology, each movable hardware component is located on a different frame of the window sash, and these components on different frames need to transmit power to each other. However, the transmission rods are usually made of a rigid material and cannot be bent at the corners of the frame. Existing technology discloses a transmission structure in which a transmission rope is installed at the corner of the frame, and a transmission rod is installed along the straight edge of the frame. The two ends of the transmission rope are connected to the transmission rods on both sides. Because the transmission rope has good flexibility, it can be bent at the corners of the frame, thereby achieving transmission between the two transmission rods.

[0004] However, after prolonged use, the transmission rope is easily worn by the corners of the sash frame, and may even break. Therefore, there is an urgent need to propose a corner guide structure and a door / window to solve the above-mentioned technical problems. Utility Model Content

[0009] A flexible transmission element is configured to be movably connected to at least a portion of the fan frame along the circumference of the fan frame. The flexible transmission element spans across the side of the roller opposite to the outer corner and is movably connected to the roller.

[0010] Optionally, the roller is provided with a guide groove that extends along the circumference of the roller and is connected end to end, and the flexible transmission component is movably connected in the guide groove.

[0011] Optionally, the number of guide grooves and flexible transmission components is at least two and they correspond one-to-one.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly 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," "over," and "on top" of the second feature includes the first feature 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. "Below," "below," and "under" the second feature includes the first feature 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.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] This embodiment provides a corner guide structure, which can reduce the friction between the roller and the flexible transmission component by rotating the roller, thereby reducing the probability of wear and breakage of the flexible transmission component.

[0034] Specifically, such as Figures 1 to 4 As shown, the corner guide structure includes a roller assembly and a flexible transmission member 300. The roller assembly includes a roller frame 210 and a roller 220. The roller frame 210 is used to connect with the outer corner portion 110 of the fan frame. The roller 220 is rotatably connected to the roller frame 210. The axial direction of the roller 220 is configured to be parallel to the thickness direction of the fan frame (i.e., the x direction in the figure). The flexible transmission member 300 is configured to be movably connected to at least a portion of the fan frame along the circumference of the fan frame. The flexible transmission member 300 spans the side of the roller 220 away from the outer corner portion 110 and is movably connected to the roller 220.

[0035] It is understandable that the thickness direction of the fan frame is the extension direction of the edge 111 of the outer corner 110. For ease of description, the thickness direction of the fan frame will be referred to as the first direction below.

[0036] The corner guide structure includes a roller assembly. A roller frame 210 connects to the outer corner portion 110. The axis of the roller 220 is configured to be parallel to a first direction, and the roller 220 is rotatably connected to the roller frame 210. A flexible transmission component 300 spans the side of the roller 220 away from the outer corner portion 110 and is movably connected to the roller 220. This reduces the friction between the roller 220 and the flexible transmission component 300 through the rotation of the roller 220, thus lowering the probability of wear and breakage of the flexible transmission component 300. The flexible transmission component 300 is a transmission element with certain flexibility, such as a steel rope, steel belt, aluminum rope, or aluminum belt.

[0037] Optionally, the roller frame 210 includes a rotating shaft 211 and two frame bodies 212. The two ends of the rotating shaft 211 are respectively connected to the two frame bodies 212. The roller 220 is located between the two frame bodies 212 and is rotatably connected to the rotating shaft 211. The two frame bodies 212 can play a certain protective role for the roller 220 and prevent the roller 220 from being bumped.

[0038] Furthermore, the roller 220 is provided with an assembly hole 223, and the rotating shaft 211 passes through the assembly hole 223. The roller 220 rotates around the rotating shaft 211. A lubricating layer is provided between the hole wall of the assembly hole 223 and the side wall of the rotating shaft 211 to reduce the noise emitted when the roller 220 rotates and improve the user experience.

[0039] The lubricating layer can be a lubricating oil layer, a lubricating grease layer, a graphite layer, or a polytetrafluoroethylene layer, etc., which will not be listed here.

[0040] Optionally, the two ends of the rotating shaft 211 are respectively inserted into the corresponding frame 212, and the two ends of the rotating shaft 211 are respectively riveted and fixed to the corresponding frame 212 to improve the overall stability of the roller frame 210.

[0041] Optionally, the flexible transmission component 300 abuts against the side of the roller 220 away from the outer corner portion 110 to press the two frames 212 onto the outer corner portion 110, thereby realizing the connection between the roller assembly and the fan frame. This structure simplifies the connection structure between the roller frame 210 and the fan frame, eliminating the need for bolts or rivets and other connecting parts, thus reducing production costs.

[0042] Optionally, both frames 212 are bonded to the outer corner portion 110, which not only connects the roller assembly to the fan frame, but also improves the stability of the connection between the roller frame 210 and the fan frame.

[0043] In this embodiment, the frame 212 includes a first frame plate 2121 and a second frame plate 2122 connected to each other. The included angle between the first frame plate 2121 and the second frame plate 2122 is the same as the angle at the corner of the outer corner portion 110. The side wall of the first frame plate 2121 facing the outer corner portion 110 is connected to the outer corner portion 110, and the side wall of the second frame plate 2122 facing the outer corner portion 110 is also connected to the outer corner portion 110, thereby forming a structure in which the roller frame 210 is connected to the outer corner portion 110. This structural design can improve the stability of the connection between the roller frame 210 and the outer corner portion 110, and on the other hand, it can reduce the weight and volume of the roller frame 210, which is beneficial for applying the roller assembly to the sash frame with limited installation space, and also helps to reduce the overall weight of the door and window.

[0044] Optionally, the roller 220 is provided with a guide groove 221, which extends along the circumference of the roller 220 and is connected end to end. The flexible transmission component 300 is movably connected in the guide groove 221. The guide groove 221 can provide guidance for the flexible transmission component 300, improve the consistency of the movement trajectory of the flexible transmission component 300 on the roller 220, and thus achieve the effect of improving the transmission accuracy.

[0045] Furthermore, the number of guide grooves 221 and flexible transmission components 300 is at least two and corresponds one-to-one. When there are multiple flexible transmission components 300, the roller 220 can provide good guidance for each flexible transmission component 300, further improving the transmission accuracy.

[0046] In this embodiment, there are two guide grooves 221. Of course, in other embodiments, the number of guide grooves 221 can also be three, four or five, etc.

[0047] Furthermore, in the axial direction of the roller 220, the middle part of the roller 220 is the reference part 222, and all guide grooves 221 are symmetrically arranged about the reference part 222. Specifically, when the number of guide grooves 221 is even (e.g., two or four guide grooves 221), half of the guide grooves 221 are located on one side of the reference part 222, and the other half of the guide grooves 221 are located on the other side of the reference part 222; when the number of guide grooves 221 is odd (e.g., three or five guide grooves 221), the center line of one guide groove 221 coincides with the reference part 222, and the remaining guide grooves 221 are located on both sides of the reference part 222. Since the flexible transmission member 300 is movably connected to the side of the roller 220 away from the outer corner portion 110, the flexible transmission member 300 applies a force to the roller 220 in the direction of the outer corner portion 110. In particular, when the flexible transmission member 300 abuts against the roller 220, the force is relatively large. The structure provided in this embodiment can make the roller 220 more uniformly subjected to force in the first direction, thereby avoiding the problem of skewing due to uneven force on the roller 220.

[0048] In one embodiment, all guide grooves 221 are evenly distributed along the axial direction of roller 220 to improve the uniformity of force on roller 220 along the first direction.

[0049] This embodiment also provides a door / window, which includes a sash frame and the aforementioned corner guide structure. The sash frame includes an outer corner portion 110, and a roller frame 210 is connected to the outer corner portion 110. The axial direction of the roller 220 is parallel to the thickness direction of the sash frame, and the flexible transmission member 300 is movably connected to at least a portion of the sash frame along its circumference. This door / window employs the aforementioned corner guide structure. The roller 220 in the roller assembly reduces the probability of wear and breakage of the flexible transmission member 300 and provides guidance for the flexible transmission member 300, thus ensuring the transmission reliability and accuracy of the flexible transmission member 300.

[0050] Furthermore, the fan frame also includes several borders 120. For example, the number of borders 120 can be three, four, five, or more. Adjacent borders 120 are connected by a corner portion, wherein the corner portion includes an outer corner portion 110 and an inner corner portion. This forms a polygonal fan frame. For example, the fan frame provided in this embodiment includes four borders 120 and four outer corner portions 110. The four borders 120 and four outer corner portions 110 are alternately connected to enclose and form a quadrilateral fan frame. Of course, in other embodiments, the fan frame can also be a triangle, pentagon, hexagon, or other shapes, which will not be listed here.

[0051] Furthermore, the number of outer corner portions 110 and roller assemblies are equal and correspond one-to-one. For example, in this embodiment, there are four outer corner portions 110 and four roller assemblies, with one roller assembly at each outer corner portion 110. This ensures that the flexible transmission member 300 can cooperate with the roller 220 when passing through each outer corner portion 110, reducing the probability of wear on the flexible transmission member 300 at the outer corner portion 110.

[0052] Furthermore, the door and window also include at least two moving parts. For example, the number of moving parts can be two, three, five or more. At least two of all moving parts are connected to the flexible transmission member 300. The following example uses three moving parts connected to the flexible transmission member 300. For clarity, the moving parts connected to the flexible transmission member 300 are referred to as the first moving part 410, the second moving part 420 and the third moving part 430. The first moving part 410, the second moving part 420 and the third moving part 430 are mutually driven through the flexible transmission member 300. The roller assembly provides guidance for the flexible transmission member 300 located at the outer corner 110, thereby improving the transmission accuracy between the first moving part 410, the second moving part 420 and the third moving part 430. Furthermore, when the flexible transmission component 300 moves, the roller 220 rotates on the shaft 211, thereby reducing the friction between the roller 220 and the flexible transmission component 300, reducing the probability of wear and breakage of the flexible transmission component 300, and improving the transmission stability and reliability between the first moving component 410, the second moving component 420 and the third moving component 430.

[0053] It should be noted that the flexible transmission component 300 can be movably connected to a portion of the fan frame or to the entire fan frame. For example, in this embodiment, the flexible transmission component 300 can be wrapped around the outer periphery of the entire fan frame or can be movably connected only to the outer periphery of the left side frame and the outer periphery of the lower side frame. Both of these methods can achieve the transmission connection of the first movable component 410, the second movable component 420, and the third movable component 430, as long as the first movable component 410, the second movable component 420, and the third movable component 430 are all connected to the flexible transmission component 300.

[0054] The aforementioned moving parts refer to components that move around the outer periphery of the sash frame and are interconnected through transmission. Taking a side-press window as an example, the moving parts can be a transmission housing, a locking rod, a side-press lower pulley, a side-press upper pulley, and a side-press lock hook, etc.; taking an inward-opening and tilt-and-turn window as an example, the moving parts can be a transmission housing, a locking rod, and a tilt-and-turn lock pin, etc., which will not be listed here.

[0055] It should be noted that the term "doors and windows" refers to both doors and windows collectively; that is, it can refer to either doors or windows. Similarly, the term "sash frame" refers to both door and window sash frames; that is, it can refer to either door or window sash frames.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
