Description

Technical Field

[0001] The present invention relates to the field of doors and windows, and particularly to an eccentric adjustment device for a hinge and doors and windows. Background Art

[0002] A door and window hinge, also known as a friction stay hinge, is mostly made of stainless steel. It is a link-type movable connection device used to connect a window sash and a window frame to enable the window to be opened and closed. Door and window hinges generally include a slide rail, a slider, a support arm, a long cantilever, a short cantilever, and an inclined cantilever. The slider is installed on the slide rail, the long cantilever is hinged between the slide rail and the support arm, the short cantilever is hinged between the slider and the support arm, and the inclined cantilever is hinged between the slider and the long cantilever.

[0003] Due to assembly errors during the assembly process of door and window hinges, that is, position offsets caused by assembly positions or the gravity of doors and windows during assembly, it is necessary to perform position calibration and position adjustment. Among them, the position offset is mainly height error and horizontal clearance error. There are existing technologies in the art to solve the height error. For example, a hinge that can be quickly disassembled and assembled, disclosed in CN113309432A on August 27, 2021, can slightly adjust the height of the window sash and adjust and relieve the drooping of the tie rod. For the existing solution to the horizontal clearance error in the art, it is to manually move the door and window or the door and window hinge after removing the bolts assembled on the door and window for adjustment and correction. However, this method is difficult and cumbersome to operate, resulting in low adjustment efficiency and poor adjustment effect. Moreover, the height adjustment device cannot play a role in horizontal adjustment. Therefore, the defects of door and window hinges in horizontal adjustment urgently need to be developed and solved by the inventor. Summary of the Invention

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides an eccentric adjustment device for a hinge and doors and windows, which solves the problem of horizontal clearance error of door and window hinges.

[0005] The technical solution adopted by the present invention to solve its problems is:

[0006] An eccentric adjustment device for a hinge, comprising an eccentric rotating member, a fixed seat, and a hinge slide plate for assembling doors and windows; one end of the eccentric rotating member is inserted into the hinge slide plate, and the other end is rotatably connected to the fixed seat. The hinge slide plate is slidably engaged with the fixed seat. By rotating the eccentric rotating member, a relative position change is generated between the hinge slide plate and the fixed seat, that is, the hinge slide plate is linearly slidably adjusted along the length direction of the hinge slide plate. Therefore, when an assembly gap problem is found during the assembly of doors and windows, the adjustment of the doors and windows can be completed by turning the eccentric rotating member. At the same time, the adjustment of the doors and windows in the horizontal direction can be achieved through the mutual cooperation of the eccentric rotating member, the fixed seat, and the hinge slide plate. This not only changes the traditional method of manually pushing the doors and windows to adjust the assembly gap by disassembling or loosening the bolts assembled on the hinge slide plate (i.e., the entire friction hinge), but also, compared with the traditional method, in addition to the more convenient adjustment operation, unexpectedly, more precise adjustment of the assembly gap can be achieved through the rotation angle of the eccentric rotating member, making the overall assembly of the doors and windows more delicate and beautiful. In addition, only by adding a fixed seat that is beneficial to the eccentric rotating member on the basis of the existing door and window components, on the premise of realizing the horizontal adjustment of the doors and windows, the effect of simple structure can be achieved, which is also beneficial to the more concise and beautiful overall assembly of the doors and windows.

[0007] Further, the eccentric rotating member includes a rotating portion and a driving portion. The rotating portion is fixedly connected to the driving portion, and the rotation axis line of the rotating portion is misaligned with the center line of the driving portion; an adjustment groove is provided on the fixed seat and is movably connected to the rotating portion; an assembly hole for inserting the driving portion is provided on the hinge slide plate. When the rotating portion abuts and moves in the adjustment groove during the eccentric rotation of the eccentric rotating member, the hinge slide plate will be driven to move through the driving portion, thereby achieving the purpose of adjusting the hinge slide plate through the eccentric rotating member.

[0008] Further, a driving groove adapted to a screwdriver or a hex wrench is provided on the driving portion.

[0009] Further, the eccentric rotating member further includes a connecting column, and the connecting column is fixedly connected to the rotating portion; an adjustment hole for inserting the connecting column is further provided on the fixed seat.

[0010] Further, a sliding adjustment groove is further provided on the fixed seat, and a limiting column slidably connected in the sliding adjustment groove is provided on the hinge slide plate. When the eccentric rotating member rotates to drive the hinge slide plate to move, under the limiting action of the sliding adjustment groove, the hinge slide plate linearly moves inside the sliding adjustment groove, achieving the purpose of linearly sliding and adjusting the hinge slide plate along the length direction of the hinge slide plate.

[0011] Further, an eccentric adjustment device for a hinge further includes a reinforcement member for assembling the fixed seat onto a door and window assembly. The fixed seat is provided with a reinforcement hole, and the reinforcement member is assembled inside the reinforcement hole, thereby ensuring that the fixed seat is assembled on a building body or a corresponding door and window assembly on the building body, achieving the purpose of keeping the fixed seat stationary, ensuring the accuracy of the eccentric rotating member driving the hinge slide plate to slide and adjust, and achieving the purpose of adjusting the assembly gap of the entire door and window.

[0012] Further, the hinge slide plate is provided with a mounting through hole, and the mounting through hole is correspondingly arranged with the reinforcement hole, that is, the mounting through hole communicates with the reinforcement hole, facilitating the assembly of the reinforcement member, that is, facilitating the assembly of the fixed seat, and improving the assembly efficiency of the eccentric adjustment device.

[0013] Further, the reinforcement member is a bolt or a screw or a rivet.

[0014] The present invention also discloses a door and window applying the above hinge eccentric adjustment device, including a window body, and the window body is fixedly connected to the hinge slide plate of the eccentric adjustment device. Specifically, the door and window is fixedly connected to the hinge slide plate. Therefore, by inserting a screwdriver or a hex wrench into the driving groove to rotate the driving part, the rotating part of the eccentric rotating member is driven to rotate inside the adjustment groove. Under the abutting action of the rotating part in the adjustment groove, the driving part is instead urged to move eccentrically, and further the hinge slide plate slides and adjusts on the fixed seat. In summary, the door and window of the hinge eccentric adjustment device has the purpose of horizontal precise adjustment during the assembly process, thereby achieving a more delicate effect after the entire door and window is assembled.

[0015] In summary, a kind of eccentric adjustment device for a hinge and a door and window provided by the present invention have the following technical effects:

[0016] 1) By the combined use of the eccentric rotating member, the fixed seat and the hinge slide plate, the purpose of horizontally adjusting the hinge slide plate is achieved, that is, the adjustment of the entire door and window in the horizontal direction is realized. It changes the traditional way of manually pushing the door and window to adjust the assembly gap by disassembling or loosening the bolts assembled on the hinge slide plate after the assembly gap appears in the door and window, solves the problem that the bolts of the hinge slide plate need to be disassembled and moved to adjust during the assembly of the existing door and window, and achieves the purpose of conveniently adjusting the entire door and window. It should be noted that here it is to adjust the position of the entire door and window in the horizontal direction, not the adjustment at the hinge position of the door and window. At the same time, through the rotation angle of the eccentric rotating member, a more precise adjustment of the assembly gap is realized, making the assembly gap of the entire door and window assembled on the building body or the door and window assembly smaller, and making the entire door body structure more delicate and beautiful;

[0017] 2) The ingenious effect of this solution lies in adding a fixed seat that is conducive to the eccentric rotating member only on the basis of the existing door and window components. This enables horizontal adjustment of the entire door and window while achieving a simple structure and convenient installation. It also facilitates a more concise and aesthetic overall assembly of the door and window. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Embodiment 1

[0026] Figure 2 Shows the assembly schematic diagram of the eccentric adjustment device of the present invention, Figure 3 Shows the exploded view of the eccentric adjustment device of the present invention. Please refer to Figure 2 and Figure 3As shown in the figure, the present invention discloses an eccentric adjustment device for a hinge, which includes an eccentric rotating member 1, a fixed seat 2, and a hinge slide plate 3 for assembling doors and windows; one end of the eccentric rotating member 1 is inserted into the hinge slide plate 3, and the other end is rotatably connected to the fixed seat 2. The hinge slide plate 3 is slidably matched with the fixed seat 2. By rotating the eccentric rotating member 1, a relative position change is generated between the hinge slide plate 3 and the fixed seat 2, that is, the hinge slide plate 3 slides linearly along the length direction of the hinge slide plate 3. Among them, the fixed seat 2 is used to be assembled on the building body or the corresponding door and window assembly on the building body, so that the fixed seat 2 is fixed, ensuring more stable adjustment of the hinge slide plate 3, that is, adjusting the position of the door and window. In addition, the sliding direction of the hinge slide plate 3 on the fixed seat 2 is parallel to the length direction of the hinge slide plate 3, so as to realize the adjustable gap distance between the door and window and both sides of the door and window assembly.

[0027] The specific adjustment principle of this eccentric adjustment device is that when assembling the door and window onto the hinge slide plate 3, check the assembly gaps on both sides of the door and window and the door and window assembly. When the assembly gap is large, or the assembly gap is small, or the assembly gaps on both sides are uneven, at this time, the eccentric rotating member 1 can be rotated. Since the center of the eccentric rotating member 1 is not at the rotation point, the distance between the farthest position on the outer edge where the eccentric rotating member 1 acts and the rotation point is not equal to the distance between the nearest position on the outer edge where the eccentric rotating member 1 acts and the rotation point. Therefore, when the position gradually moves from the farthest position to the nearest position, a displacement variable will be generated, which is the adjustable displacement variable of the eccentric rotating member 1. When the eccentric rotating member 1 rotates, since the fixed seat 2 interacting with the eccentric rotating member 1 is fixed, the position of the rotation point changes, prompting the hinge slide plate 3 to slide, so as to realize the linear sliding adjustment of the hinge slide plate 3 along the length direction of the hinge slide plate 3, and further achieve the purpose of adjusting the assembly gap of the door and window within the adjustable displacement variable range of the eccentric rotating member 1.

[0028] Based on the above, when problems with assembly gaps are found during the assembly of doors and windows, the adjustment of the doors and windows can be completed by rotating the eccentric rotating member 1. At the same time, the adjustment of the doors and windows in the horizontal direction (the length direction of the hinge slide plate 3) can be achieved through the mutual cooperation of the eccentric rotating member 1, the fixed seat 2, and the hinge slide plate 3. This not only changes the traditional method of manually pushing the door and window to adjust the assembly gap by disassembling or loosening the bolts assembled on the hinge slide plate 3 after the assembly gap appears in the traditional doors and windows. Compared with the traditional method, in addition to the more convenient adjustment operation, unexpectedly, more precise adjustment of the assembly gap can be achieved through the rotation angle of the eccentric rotating member 1, making the overall assembly of the doors and windows more delicate and beautiful. In addition, only by adding a fixed seat 2 that is beneficial to the eccentric rotating member 1 on the basis of the existing door and window assembly, on the premise of realizing the horizontal adjustment of the doors and windows, the effect of simple structure can be achieved, which is also beneficial to the more concise and beautiful overall assembly of the doors and windows.

[0029] In this embodiment, specifically, please combineFigure 1 As shown Figure 1 Figure 1 shows a schematic structural diagram of the eccentric rotating member 1 in an embodiment of the present invention. The eccentric rotating member 1 includes a rotating portion 11 and a driving portion 12. Among them, the rotating portion 11 can be a circular wheel or a cam body. The rotating portion 11 is fixedly connected to the driving portion 12, and the rotation axis line of the rotating portion 11 is offset from the center line of the driving portion 12. Specifically, the rotating portion 11 and the driving portion 12 can be integrally formed, welded, or connected and formed by using existing technologies in the mechanical field. Among them, the rotation axis line of the rotating portion 11 is parallel to and does not coincide with the center line of the driving portion 12. Then, the driving portion 12 performs eccentric rotation around the rotation axis line of the rotating portion 11, and the displacement variable is twice the distance between the rotation axis line of the rotating portion 11 and the center line of the driving portion 12. Further, an adjustment groove 21 for movably connecting with the rotating portion 11 is provided on the fixed seat 2, that is, the rotating portion 11 is located in the adjustment groove 21, and the rotating portion 11 abuts against the inside of the adjustment groove 21. The adjustment groove 21 is preferably a waist-shaped groove or a circular counterbore with a diameter larger than the diameter of the rotating portion 11. Then, when the driving portion 12 is rotated, due to the action of the rotating portion 11 on the adjustment groove 21, the driving portion 12 performs eccentric rotation around the rotation axis line of the rotating portion 11, achieving the purpose of the eccentric movement of the eccentric rotating member 1; furthermore, an assembly hole 31 for inserting the driving portion 12 is provided on the hinge slide plate 3. Therefore, when the eccentric rotating member 1 performs eccentric rotation, it will drive the hinge slide plate 3 to move, and further achieve the adjustment purpose of the hinge slide plate 3 through the eccentric rotating member 1.

[0030] For the convenience of the operator to rotate the driving portion 12, specifically, please refer to Figure 2 and Figure 3 As shown, a driving groove 13 adapted to a screwdriver or a hex wrench is provided on the driving portion 12, that is, a flat groove or a cross groove adapted to a screwdriver or an internal hexagon groove adapted to a hex wrench is provided on the driving portion 12. Then, the operator can insert tools such as a screwdriver or a hex wrench into the driving groove 13 to rotate the driving portion 12 to apply a force.

[0031] Further, specifically, please refer to Figure 1 and Figure 3 As shown, the eccentric rotating member 1 further includes a connecting column 14, and the connecting column 14 is fixedly connected to the rotating portion 11; an adjustment hole 22 for inserting the connecting column 14 is further provided on the fixed seat 2.

[0032] Further, specifically in combination with Figure 2 and Figure 3As shown, a sliding adjustment groove 23 is further provided on the fixed seat 2, and a limit post 32 which is slidably connected in the sliding adjustment groove 23 is provided on the hinge slide plate 3. Preferably, the groove width of the sliding adjustment groove 23 is adapted to the size of the limit post 32. Therefore, the limit post 32 is limited to move inside the sliding adjustment groove 23. Then, when the eccentric rotating member 1 rotates to drive the hinge slide plate 3 to move, under the limiting action of the sliding adjustment groove 23, the hinge slide plate 3 moves linearly in the sliding adjustment groove 23, achieving the purpose of linearly sliding and adjusting the hinge slide plate 3 along the length direction of the hinge slide plate 3.

[0033] Furthermore, specifically in combination with Figure 2 and Figure 3 shown, the eccentric adjustment device for the hinge further includes a reinforcement member 4 for assembling the fixed seat 2 to the door and window assembly. Here, the reinforcement member 4 is preferably a screw, or it can be a bolt, or it can be a rivet. A reinforcement hole 24 is provided on the fixed seat 2, and the reinforcement member 4 is assembled inside the reinforcement hole 24. Among them, the reinforcement hole 24 can be a through hole or a threaded hole adapted to the reinforcement member 4, thus ensuring that the fixed seat 2 is assembled on the building body or the corresponding door and window assembly on the building body, achieving the purpose of fixing the fixed seat 2 immobile, ensuring the accuracy of the eccentric rotating member 1 rotating to drive the hinge slide plate 3 to slide and adjust, and achieving the purpose of adjusting the assembly gap of the door and window.

[0034] For the convenience of assembling the reinforcement member 4, that is, for the convenience of assembling the fixed seat 2 and improving the assembly efficiency of the eccentric adjustment device, specifically in combination with Figure 2 and Figure 3 shown, an installation through hole 33 is provided on the hinge slide plate 3, and the installation through hole 33 is correspondingly arranged with the reinforcement hole 24, that is, the installation through hole 33 communicates with the reinforcement hole 24. Then, when assembling the fixed seat 2, the reinforcement member 24 can pass through the installation through hole 33 and then be assembled into the reinforcement hole 24 to achieve the purpose of installing and fixing the fixed seat 2, thereby improving the installation efficiency.

[0035] Embodiment 2

[0036] The present invention also provides a door and window based on the eccentric adjustment device of Embodiment 1. Since the assembly of the door and window on the hinge slide plate 3 is prior art in the art, no drawings are shown in this embodiment. The door and window with the hinge eccentric adjustment device includes a window body, and the window body is fixedly connected to the hinge slide plate 3 of the eccentric adjustment device.

[0037] In this embodiment, the door and window is specifically fixedly connected to the hinge slide plate 3. Then, a screwdriver or a hex wrench is inserted into the driving groove 13 to rotate the driving part 12, driving the rotating part 11 of the eccentric rotating part 1 to rotate inside the adjusting groove 21. Under the abutting action of the rotating part 11 in the adjusting groove 21, the driving part 12 is instead forced to move eccentrically, and further the hinge slide plate 3 slides and adjusts on the fixed seat 2. Therefore, the door and window of this hinge eccentric adjustment device has the purpose of horizontal precise adjustment during the assembly process, thereby achieving a more beautiful effect after the entire door and window is assembled.
