Description

Technical Field

[0001] The present invention relates to the field of doors and windows, and particularly to an adjustable door and window hinge and a door and window. 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 open and close. A door and window hinge generally includes a slide rail, a slider, a support arm, a long cantilever, a short cantilever, and an inclined cantilever. Among them, 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 the door and window hinge, that is, position offsets in the horizontal direction are caused by the assembly position or the gravity of the door and window during assembly. Therefore, position calibration and adjustment are required. The existing solution in the art for horizontal clearance errors 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, the adjustment effect is not good, and there is a risk that the rotating piece on the door and window hinge is easily separated from the card slot of the door and window frame, causing the door and window to fall. 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 adjustable door and window hinge and a door and window, which achieve the purpose of facilitating the adjustment of the door and window in the horizontal direction. At the same time, it also avoids the door and window from being prone to falling during horizontal adjustment, and improves the safety of the door and window during the adjustment process.

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

[0006] An adjustable door and window hinge includes a hinge assembly, a limit fixing assembly for limiting on a door and window frame, and a horizontal adjustment assembly for adjusting the horizontal position of the hinge assembly; the adjustment end of the horizontal adjustment assembly and the limit fixing assembly are both connected to the hinge fixing member of the hinge assembly. Among them, the hinge assembly is clamped and limited in the card slot of the door and window frame through the limit fixing assembly, so that the hinge assembly is stably assembled on the door and window frame during the horizontal adjustment process, avoiding the hinge assembly from detaching from the door and window frame, and improving the safety of the door and window hinge during the assembly and adjustment process. Further, the horizontal adjustment assembly is fixed on the door and window frame, and its adjustment end is connected to the hinge assembly. Then, by driving the adjustment end of the horizontal adjustment assembly, the hinge assembly linearly moves horizontally on the door and window frame, thereby achieving the purpose of horizontal adjustment of the hinge assembly on the door and window frame. Therefore, only by the horizontal adjustment assembly can the horizontal adjustment of the door and window be realized, making the movement adjustment of the door and window in the horizontal direction more convenient and effective.

[0007] Furthermore, the horizontal adjustment component includes an eccentric rotating member and a fixed seat, and the hinge fixing member is movably connected to the fixed seat through the eccentric rotating member.

[0008] Furthermore, the eccentric rotating member includes a rotating portion and a driving connection portion. The rotating portion is fixedly connected to the driving connection portion, and the rotation axis line of the rotating portion is offset from the center line of the driving connection portion. An adjustment groove for movably assembling with the rotating portion is provided on the fixed seat. When the driving connection portion rotates to drive the rotating portion to rotate, the driving connection portion synchronously makes an eccentric rotation centered on the rotating portion, thereby driving the hinge fixing member to move along the length direction of the adjustment groove. Specifically, when the rotating portion is driven to rotate, since the rotation axis line of the rotating portion is offset from the center line of the driving connection portion and the side wall of the rotating portion abuts against the groove wall of the adjustment groove, the rotating portion also generates a displacement in the horizontal direction during the rotation process, achieving the effect of the eccentric rotation of the eccentric rotating member. At the same time, the other end of the driving connection portion is inserted into the hinge fixing member, that is, a hinge driving hole for inserting the other end of the driving connection portion is provided on the hinge fixing member. Then, while the driving connection portion rotates in the hinge driving hole, the horizontal displacement generated by the eccentric movement of the eccentric rotating member also acts on the hinge fixing member, driving the hinge fixing member to generate a horizontal displacement, achieving the purpose of horizontally adjusting the hinge fixing member.

[0009] Furthermore, a sliding adjustment groove is further provided on the fixed seat, and a sliding limiting portion slidably connected in the sliding adjustment groove is provided on the hinge fixing member. Therefore, the sliding limiting portion is limited to move inside the sliding adjustment groove. Then, when the eccentric rotating member rotates to drive the hinge fixing member to move, under the limiting action of the sliding adjustment groove, the hinge fixing member linearly moves in the sliding adjustment groove, achieving the purpose of linearly sliding adjustment of the hinge fixing member along the length direction of the hinge fixing member and achieving the purpose of horizontally adjusting the hinge assembly.

[0010] Furthermore, the horizontal adjustment component further includes a fixing member, and the fixing member is connected to the fixed seat. Then, the fixed seat is assembled and fixed to the door and window frame body through the fixing member, achieving the purpose of keeping the fixed seat stationary, ensuring the accuracy of the sliding adjustment of the hinge fixing member driven by the rotation of the eccentric rotating member, and achieving the purpose of adjusting the assembly gap of the door and window.

[0011] Furthermore, the limit fixing component includes a rotating piece body, a connecting piece and a limiting piece. The rotating piece body is rotatably connected to the hinge fixing member through the connecting piece. The limiting piece is located within the rotation range of the rotating piece body, and the limiting piece is connected to the hinge fixing member. Then, the limiting piece is arranged within the rotation range of the rotating piece body to ensure that the limiting piece can abut against and limit the rotation of the rotating piece body, thereby achieving the purpose of preventing the rotating piece body from disengaging from the card slot of the door and window frame body.

[0012] Furthermore, the limit fixing component further includes a fitting, and the fitting is connected to the hinge fixing member. Then, after the hinge fixing member is horizontally corrected, the fitting is installed on the hinge fixing member, so that the hinge fixing member is assembled and fixed at the corrected position of the door and window frame, ensuring that the hinge fixing member and the door and window no longer shift.

[0013] Furthermore, the fitting is located inside the rotation range of the swivel blade body, so that the swivel blade body can only swing between the fitting and the limiting member, and will not disengage from the notch of the door and window assembly, achieving the unexpected effect of double anti-disengagement of the swivel blade body.

[0014] Furthermore, the limiting member and the fitting are located on the center line of the hinge fixing member along the length direction of the hinge fixing member. On the one hand, when the limiting member and the fitting are assembled on the hinge fixing member, both the limiting member and the fitting are located in the middle of the notch of the door and window assembly, ensuring that the swivel blade body will not disengage from the notch during any swing. On the other hand, both sides of the swivel blade body are clamped on the door and window assembly, so that the contact area of the swivel blade body with the door and window assembly is larger and the load that can be borne is greater, and the stress effect of the door and window hinge is better.

[0015] The present invention also discloses a door and window, including a door and window body and the above-mentioned door and window hinge. The hinge assembly of the door and window hinge further includes a movable assembly, the movable assembly is hinged to the hinge fixing member, and the door and window body is installed on the movable assembly.

[0016] In summary, the adjustable door and window hinge and door and window provided by the present invention have the following technical effects:

[0017] The door and window hinge and the door and window ensure that the door and window hinge and the door and window are clamped on the door and window frame during horizontal movement adjustment through the limit fixing component, ensuring the stability and safety of the door and window hinge and the door and window during the movement adjustment process. At the same time, the door and window hinge and the door and window realize the horizontal movement adjustment of the door and window and the door and window hinge through the horizontal adjustment component, replacing the traditional way of pushing the door and window to move, making the horizontal movement adjustment of the door and window more convenient and effective.

[0031] Embodiment 1

[0032] Figure 1Shows the overall structure diagram of the adjustable door and window hinge of the present invention, Figure 2 Shows the exploded schematic diagram of the adjustable door and window hinge of the present invention, Figure 3 Shows the limit state diagram of the horizontal adjustment component 3 in the present invention, Figure 4 Shows Figure 2 The partial enlarged view in the direction A of Figure 8 Shows Figure 2 The partial enlarged view in the direction B of Figure 9 Shows Figure 3 The partial enlarged view in the direction C of, in which, the hinge fixing member 11 is shown in cross-section. For details, please refer to Figures 1 to 4 And in combination with Figure 8 、 Figure 9 As shown, the present invention discloses an adjustable door and window hinge, including a hinge assembly 1, a limit fixing assembly 2 for limiting the door and window frame, and a horizontal adjustment assembly 3 for adjusting the horizontal position of the hinge assembly 1; the adjustment end of the horizontal adjustment assembly 3 and the limit fixing assembly 2 are both connected to the hinge fixing member 11 of the hinge assembly 1.

[0033] In this embodiment, the hinge assembly 1 is clamped and limited in the card slot of the door and window frame through the limit fixing assembly 2, so that the hinge assembly 1 is stably assembled on the door and window frame during the horizontal adjustment process, avoiding the hinge assembly 1 from detaching from the door and window frame, and improving the safety of the door and window hinge during the assembly and adjustment process.

[0034] Furthermore, the horizontal adjustment assembly 3 is fixedly assembled on the door and window frame, and its adjustment end is connected to the hinge assembly 1. Then, by driving the adjustment end of the horizontal adjustment assembly 3, the hinge assembly 1 can be linearly moved horizontally on the door and window frame. Therefore, only through the horizontal adjustment assembly 3 can the horizontal adjustment of the door and window be conveniently and effectively realized.

[0035] Among them, for details, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7, the horizontal adjustment component 3 includes an eccentric rotating member 31 and a fixed seat 32. The hinge fixing member 11 is movably connected to the fixed seat 32 through the eccentric rotating member 31. Specifically, the fixed seat 32 is bolted to the door and window frame body to achieve the purpose of fixing the horizontal adjustment component 3 on the door and window frame body. Further, the eccentric rotating member 31 includes a rotating portion 311 and a driving connection portion 312. Among them, the driving connection portion 312 is the adjustment end of the horizontal adjustment component 3. The rotating portion 311 is fixedly connected to the driving connection portion 312, and the rotation axis line of the rotating portion 311 is offset from the center line of the driving connection portion 312, that is, the rotation axis line of the rotating portion 311 is parallel to and does not coincide with the center line of the driving connection portion 312; an adjustment groove 321 for movably assembling with the rotating portion 311 is provided on the fixed seat 32; when the driving connection portion 312 rotates to make the rotating portion 311 rotate, the driving connection portion 312 synchronously makes an eccentric rotation around the center of the rotating portion 311, thereby driving the hinge fixing member 11 to move along the length direction of the adjustment groove 321.

[0036] The above-mentioned rotating portion 311 can be a circular wheel or a cam body. The rotating portion 311 and the driving connection portion 312 can be integrally formed, welded, or connected by using existing technologies in the mechanical field to form a connection between the rotating portion 311 and the driving connection portion 312.

[0037] A connection adjustment hole 323 is provided on the fixed seat 32. The connection adjustment hole 323 is preferably an oval hole to facilitate a certain offset of the driving connection portion 312 in the connection adjustment hole 323 during rotation. One end of the driving connection portion 312 of the eccentric rotating member 31 is inserted into the connection adjustment hole 323, then the rotating portion 311 is driven to rotate. Since the rotation axis line of the rotating portion 311 is offset from the center line of the driving connection portion 312, and the side wall of the rotating portion 311 abuts against the groove wall of the adjustment groove 321, the rotating portion 311 also generates a displacement in the horizontal direction during rotation, achieving the effect of eccentric rotation of the eccentric rotating member 31. At the same time, the other end of the driving connection portion 312 is inserted into the hinge fixing member 11, that is, a hinge driving hole 112 for inserting the other end of the driving connection portion 312 is provided on the hinge fixing member 11. Then, while the driving connection portion 312 rotates in the hinge driving hole 112, the horizontal displacement generated by the eccentric movement of the eccentric rotating member 31 also acts on the hinge fixing member 11, driving the hinge fixing member 11 to generate a horizontal displacement, achieving the purpose of horizontal movement adjustment of the hinge fixing member 11.

[0038] To further ensure the horizontal movement of the hinge fixing member 11 under the eccentric rotating member 31, specifically, please refer to Figure 5 and Figure 7As shown, a sliding adjustment groove 322 is further provided on the fixed seat 32, and a sliding limit portion 111 slidably connected in the sliding adjustment groove 322 is provided on the hinge fixing member 11. Preferably, the groove width of the sliding adjustment groove 322 is adapted to the size of the sliding limit portion 111. Therefore, the sliding limit portion 111 is limited to move inside the sliding adjustment groove 322. Then, when the eccentric rotating member 31 rotates to drive the hinge fixing member 11 to move, under the limiting action of the sliding adjustment groove 322, the hinge fixing member 11 moves linearly in the sliding adjustment groove 322, achieving the purpose of linearly sliding adjustment of the hinge fixing member 11 along the length direction of the hinge fixing member 11, and achieving the purpose of horizontal movement adjustment of the hinge assembly 1.

[0039] For details, please refer to Figure 4 , the horizontal adjustment assembly 3 further includes a fixing member 33, and the fixing member 33 is connected to the fixed seat 32. Specifically, the fixing member 33 is preferably a screw, and bolts or rivets are also optional. The fixed seat 32 is assembled and fixed to the door and window frame through the fixing member 33, achieving the purpose of keeping the fixed seat 32 stationary, ensuring the accuracy of the sliding adjustment of the hinge fixing member 11 driven by the rotation of the eccentric rotating member 31, and achieving the purpose of adjusting the assembly gap of the door and window.

[0040] To achieve the above purpose that the hinge assembly 1 is clamped and limited in the card slot of the door and window frame by the limit fixing assembly 2, so that the hinge assembly 1 is stably assembled on the door and window frame during the horizontal adjustment process, the inventor provides a preferred solution. For details, please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 , the limit fixing assembly 2 includes a rotating piece body 21, a connecting piece 22 and a limiting piece 23. Among them, the connecting piece 22 is preferably a rivet, and the limiting piece 23 can be a bolt, a screw, a rivet, a shaft pin or a plug. The rotating piece body 21 is rotatably connected to the hinge fixing member 11 through the connecting piece 22. The limiting piece 23 is located within the rotation range of the rotating piece body 21, and the limiting piece 23 is connected to the hinge fixing member 11. Specifically, the limiting piece 23 is threadedly connected or inserted and connected to the hinge fixing member 11. Then, the limiting piece 23 is arranged within the rotation range of the rotating piece body 21 to ensure that the limiting piece 23 can abut against and limit the rotation of the rotating piece body 21, thereby achieving the purpose of preventing the rotating piece body 21 from detaching from the card slot of the door and window frame.

[0041] Furthermore, for details, please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9The limiting fixing component 2 also includes an assembly part 24, where the assembly part 24 is preferably a screw or a bolt. The assembly part 24 is connected to the hinge fixing part 11. When the hinge fixing part 11 is horizontally corrected, the assembly part 24 is installed on the hinge fixing part 11, so that the hinge fixing part 11 is assembled and fixed in the corrected position of the door and window frame, ensuring that the hinge fixing part 11 and the door and window will no longer be offset.

[0042] For further details, please refer to Figure 9 As shown, the assembly part 24 is located inside the rotation range of the rotary vane body 21. Therefore, the assembly part 24 not only connects and fixes the hinge fixing part 11 to the door and window assembly, but also limits the rotary vane body 21 at another position, so that the rotary vane body 21 can only swing between the assembly part 24 and the limiting part 23, and will not fall off from the notch of the door and window assembly, thereby achieving the unexpected effect of double anti-falling off of the rotary vane body 21.

[0043] For further details, please refer to Figure 9 As shown, the limit member 23 and the assembly member 24 are located on the center line of the hinge fixing member 11 along the length direction of the hinge fixing member 11. On the one hand, when the limit member 23 and the assembly member 24 are assembled on the hinge fixing member 11, the limit member 23 and the assembly member 24 are both located in the middle of the slot of the door and window assembly, ensuring that the rotary vane body 21 will not escape from the slot when swinging at will. On the other hand, the two side edges of the rotary vane body 21 are clamped on the door and window assembly, so that the force-bearing area of the rotary vane body 21 in contact with the door and window assembly is larger, and the load that can be borne is larger, so the force-bearing effect of the door and window hinge is better.

[0044] To sum up, the assembly steps and principles of adjustable door and window hinges are:

[0045] (Assemble and fix the fixing seat 32 on the door and window frame through the fixing member 33, and assemble the eccentric rotating member 31 with the fixing seat 32);

[0046] Step S1, after rotating the connecting member 22 to adjust the rotating blade body 21 to a suitable angle, the door and window hinge is placed on the door and window frame, and the hinge fixing member 11 of the door and window hinge is plugged into and matched with the driving connecting part 312 of the eccentric rotating member 31.

[0047] Step S2, rotating the connecting member 22 to rotate the vane body 21 to a certain angle, on the one hand, the vane body 21 is initially clamped on the door and window frame, on the other hand, it is convenient for the next step to install the stopper 23 more properly.

[0048] Step S3: Assemble and connect the limiting member 23 to the hinge fixing member 11, and rotate the connecting member 22 again so that the side of the rotating vane body 21 abuts against the limiting member 23. At this time, the clamping force receiving surface between the rotating vane body 21 and the clamping groove of the door and window frame is the largest, achieving the best clamping effect.

[0049] Step S4: Drive the driving connection part 312 of the eccentric rotating member 31 to move eccentrically to push the hinge fixing member 11 to move linearly until the gaps between the two sides of the hinge fixing member 11 or the two sides of the door and window and the door and window frame are symmetrical.

[0050] Step S5: Assemble and connect the fitting 24 to the hinge fixing member 11, and assemble and fix the hinge fixing member 11 on the door and window frame.

The hinge assembly 1 of the door and window hinge further includes a movable assembly 12. The movable assembly 12 is hinged to the hinge fixing member 11, and the door and window body is installed on the movable assembly 12. Specifically, the movable assembly 12 includes a support arm, a long cantilever, a short cantilever, and an inclined cantilever. According to the prior art in this field, the support arm, the long cantilever, the short cantilever, and the inclined cantilever are hinged to each other, and the support arm, the long cantilever, the short cantilever, and the inclined cantilever are all hinged to the hinge assembly 1 and the hinge fixing member 11, and the door and window body is bolted to the movable assembly 12.
