Description

Technical Field

[0001] This invention relates to the field of door and window hardware technology, and in particular to a door and window hinge structure. Background Technology

[0002] Hinges are mechanical devices used to connect two fasteners and allow relative rotation between them. They are commonly used in the installation of doors and windows. However, during installation or after prolonged use, gaps may appear between the door / window sash and the frame, causing them to fail to meet technical or usage requirements. Hinges are then needed to adjust these gaps. However, traditional hinge structures lack gap adjustment capabilities, and even existing adjustable hinges only allow adjustment in one direction. Therefore, when door / window installation has progressed to a certain stage, or gaps appear after use causing misalignment or vertical discrepancies, the doors and windows must be disassembled, repositioned, and reinstalled – a cumbersome and labor-intensive process. Therefore, it is necessary to provide a hinge structure that allows for flexible adjustment of door / window gaps to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that traditional door and window hinges, which lack adjustment functions or have only one adjustment direction, require the disassembly of doors and windows for adjustment, resulting in complicated procedures and high costs. This invention provides a door and window hinge structure that allows for four-way adjustment of the gap size between door and window frames, without disassembly, offering high flexibility and ease of operation.

[0004] To address the aforementioned technical problems, embodiments of the present invention disclose a door and window hinge structure, comprising: a hinge, one end of which is used to connect to a first door and window frame; a connecting fastener, used to connect to a second door and window frame and connected to the other end of the hinge; a lateral adjustment assembly, at least a portion of which is connected between the connecting fastener and the other end of the hinge, the lateral adjustment assembly being movable vertically along the longitudinal direction to allow the connecting fastener to move horizontally left and right relative to the lateral adjustment assembly; and a longitudinal adjustment assembly capable of moving vertically along the longitudinal direction to drive the connecting fastener to move vertically relative to the hinge along the longitudinal direction.

[0005] Using the above technical solution, the hinge and the connecting fastener are interconnected and respectively fixed to the first and second door and window frames. The lateral adjustment component is located between the hinge and the connecting fastener. When the lateral adjustment component is adjusted to move vertically up and down, the connecting fastener will move horizontally left and right relative to it, thereby driving the second door and window frame fixed to the connecting fastener to move horizontally left and right, thus realizing the left and right adjustment of the lateral gap between the first and second door and window frames. At the same time, when the longitudinal adjustment component is adjusted to move vertically up and down, it will drive the hinge to move vertically, causing the connecting fastener to move vertically up and down, thereby driving the second door and window frame fixed to the connecting fastener to move vertically up and down, thus realizing the up and down adjustment of the longitudinal gap between the first and second door and window frames. Therefore, the door and window hinge structure of the present invention can simultaneously adjust the gap of the second door and window frame in four directions (up and down, left and right) without disassembling the door and window, saving time and effort, simplifying operation, and having high flexibility.

[0006] According to another specific embodiment of the present invention, the lateral adjustment assembly includes a lateral adjustment member and a lateral adjustment screw. The lateral adjustment member is located between the connecting fixing member and the other end of the hinge. The lateral adjustment member includes a first lateral adjustment body and a second lateral adjustment body connected to each other. The first lateral adjustment body extends along the longitudinal direction, and the second lateral adjustment body extends along the lateral direction. The second lateral adjustment body is provided with a first threaded hole.

[0007] The connecting fastener includes a first part and a second part that are spaced apart along the longitudinal direction. The first part is provided with a through hole corresponding to the first threaded hole. The second lateral adjustment body is located between the first part and the second part. The lateral adjustment screw is located at the through hole and is threadedly connected to the first threaded hole.

[0008] The first lateral adjustment body engages with the second inclined surface, such that when the lateral adjustment screw is driven to rotate by the tool located in the through hole, the first lateral adjustment body moves up and down along the longitudinal direction, and the second part moves laterally relative to the first lateral adjustment body.

[0009] According to another specific embodiment of the present invention, the first lateral adjustment body moves upward along the longitudinal direction, and the second part moves in the opposite direction to the first lateral adjustment body in the lateral direction; the first lateral adjustment body moves downward along the longitudinal direction, and the second part moves in the opposite direction to the first lateral adjustment body in the lateral direction.

[0010] Using the above technical solution, only tooling is needed. The horizontal adjustment screw is adjusted through the through hole. The horizontal adjustment screw cooperates with the first threaded hole on the second horizontal adjustment body to make the first horizontal adjustment body move vertically up and down. At the same time, the first horizontal adjustment body can cooperate with the second inclined surface to make the second part of the connecting fastener move horizontally left and right away from or towards the first horizontal adjustment body, thereby realizing the left and right horizontal adjustment of the door and window. The adjustment operation is simple.

[0011] According to another specific embodiment of the present invention, the first lateral adjustment body is provided with an inclined protrusion on the side facing the second part, and the second part is provided with an inclined groove on the side facing the first lateral adjustment body, wherein the inclined protrusion is disposed in the inclined groove and is engaged by an inclined surface.

[0012] By adopting the above technical solution, it is only necessary to set a slanted protrusion in the first lateral adjustment body of the lateral adjustment component and a slanted groove in the second part of the connecting fastener. The lateral adjustment of the door and window can be realized by the cooperation of the slanted protrusion and the slanted groove and the longitudinal movement of the lateral adjustment component, thus achieving efficient lateral adjustment while meeting low processing costs.

[0013] According to another specific embodiment of the present invention, the inclined protrusion includes a first inclined surface and a first flat surface, and the inclined groove includes a second inclined surface and a second flat surface; in an initial state, the first flat surface and the second flat surface are in contact, and the first inclined surface and the second inclined surface are in contact; in a lateral adjustment state, the first flat surface and the second flat surface are separated along the longitudinal direction, and the first inclined surface and the second inclined surface are in contact; in the initial state, the first inclined surface and the second inclined surface have a first contact area, and in the lateral adjustment state, the first inclined surface and the second inclined surface have a second contact area, wherein the first contact area is larger than the second contact area.

[0014] By adopting the above technical solution, by setting the inclined protrusion and the inclined groove, the original longitudinal force that the lateral adjustment component is subjected to as the driving force is transformed into a lateral component force, thereby guiding the first lateral adjustment body and the second part from the initial longitudinal movement to the lateral movement.

[0015] According to another specific embodiment of the present invention, the longitudinal adjustment assembly includes a longitudinal adjustment screw and a second threaded hole; the connecting fastener further includes a bearing portion, the bearing portion being disposed in the second portion, and the second threaded hole being disposed in the bearing portion and the first portion;

[0016] The hinge includes a bent portion that extends longitudinally and is located between the support portion and the first portion; the longitudinal adjusting screw is threadedly connected to the second threaded hole and abuts against the end of the bent portion to drive the support portion or the first portion to move up and down relative to the bent portion along the longitudinal direction, and to abut the end of the bent portion against the support portion or the first portion.

[0017] By adopting the above technical solution, it is only necessary to rotate the longitudinal adjustment screw to cooperate with the second threaded hole located in the bearing part and / or the first part, so that the bearing part or the first part moves up and down in the longitudinal direction relative to the bent part of the hinge, thereby driving the second door and window frame fixedly connected to the bearing part or the first part to move up and down in the longitudinal direction, thereby realizing the longitudinal up and down adjustment of the door and window sash. The operation is simple and the processing and manufacturing cost is low.

[0018] According to another specific embodiment of the present invention, the hinge further includes a hinge portion and a connecting portion, the hinge portion being used for rotatable connection with the first door and window frame; the bent portion is disposed on the side of the connecting portion facing the connecting fastener, and the bent portion is arranged perpendicular to the connecting portion.

[0019] According to another specific embodiment of the present invention, the connecting fastener further includes a second fixing seat that is longitudinally connected to the first part, the second part and the bearing part, the second fastener being located on the side of the first part, the second part and the bearing part, and the second fastener being used to connect with the second door and window frame.

[0020] According to another specific embodiment of the present invention, along the longitudinal direction, the surface of the second fastener near the first portion is provided with a longitudinal adjustment mark line, and the surface of the second fastener near the bearing portion is provided with a transverse adjustment mark line.

[0021] By adopting the above technical solution and setting horizontal and vertical adjustment marking lines on the connecting fasteners, the adjustment amount can be observed during the four-way adjustment process, making the four-way adjustment more flexible and accurate.

[0022] According to another specific embodiment of the present invention, the door and window hinge structure further includes a connecting screw and a washer. The connecting part, the first lateral adjustment body, and the second part are all provided with connecting holes. The washer is sleeved on the connecting screw and fits against the surface of the connecting part facing away from the first lateral adjustment body. The connecting screw passes through the connecting hole to detachably connect the connecting part, the first lateral adjustment body, and the second part in sequence along the lateral direction.

[0023] By adopting the above technical solution, the hinge, lateral adjustment component and connecting fastener are connected by connecting screws and washers, so that the door and window hinge structure of the present invention has the advantages of easy disassembly and assembly, not easy to be damaged, simple structure and replaceable parts, and at the same time, it is easy to make four-way adjustment.

[0038] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention is presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a deep understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] Please see Figure 1 and Figure 2In this embodiment of the application, a door and window hinge structure includes a hinge 1, a connecting fastener 2, a lateral adjustment component 3, and a longitudinal adjustment component 4. One end of the hinge 1 is fixedly connected to a first door and window frame 8, and the other end is connected to the connecting fastener 2. The connecting fastener 2 is fixedly connected to a second door and window frame 9. The first door and window frame 8 is used to fix itself to the wall, and the second door and window frame 9 is used to install door and window sashes. Therefore, in use, the door and window hinge structure of this embodiment of the application is such that the first door and window frame 8 and one end of the hinge 1 are aligned longitudinally (e.g., ...). Figure 2 (As shown in the Z-direction) is fixed. The first door / window frame 8 and the second door / window frame 9 are rotatably connected by a hinge 1, so that the first door / window frame 8 and the second door / window frame 9 are in a position as shown in the Z-direction. Figure 3a The closed state shown or as Figure 3b The state shown is the on state.

[0041] The aforementioned horizontal adjustment component 3 can realize the left and right horizontal adjustment of the second door and window frame 9, specifically as follows:

[0042] The lateral adjustment component 3 is connected between the other end of the hinge 1 and the connecting fastener 2. The lateral adjustment component 3 can move along the longitudinal direction (e.g., ...). Figure 2 (As shown in the Z direction) upwards (e.g.) Figure 2 Move the connecting fastener 2 relative to the lateral adjusting member 31 in the lateral direction (as shown in the m direction), so that the connecting fastener 2 moves in the lateral direction (as shown in the m direction). Figure 2 (As shown in the Y direction) to the right (e.g.) Figure 2 The movement (as shown in the p direction) drives the second door and window frame 9, which is fixedly connected to the connecting fastener 2, to move laterally to the right, thereby realizing the lateral rightward adjustment of the second door and window frame 9.

[0043] Alternatively, the lateral adjustment component 31 can be adjusted vertically downwards (e.g., ...). Figure 2 (As shown in the n-direction) moves, driving the connecting fixing member 2 to move laterally to the left relative to the lateral adjusting member 3, as shown in the n-direction. Figure 2 The movement (as shown in the o direction) drives the second door and window frame 9, which is fixed to the connecting fastener 2, to move laterally to the left, thereby achieving the lateral leftward adjustment of the second door and window frame 9.

[0044] The aforementioned vertical adjustment component 4 can realize the vertical adjustment of the second door and window frame 9, specifically as follows:

[0045] Along the longitudinal direction (e.g.) Figure 2 As shown in the Z-direction), the longitudinal adjustment component 4 can cooperate with the hinge 1 to move upward (as shown in the Z-direction). Figure 2 As shown in the middle m direction, the hinge 1 moves, and since the connecting fastener 2 is fixed relative to the hinge 1, the connecting fastener 2 can be driven downward relative to the hinge 1 (as shown in the middle m direction). Figure 2 The movement (as shown in the n direction) causes the second door and window frame 9, which is fixedly connected to the connecting fastener 2, to move downwards longitudinally, thereby achieving the downward adjustment of the second door and window frame 9.

[0046] Alternatively, the longitudinal adjustment component 4 can move downward in the longitudinal direction in conjunction with the hinge 1, so that the connecting fastener 2 moves upward relative to the hinge 1, thereby driving the second door and window frame 9, which is fixedly connected to the connecting fastener 2, to move upward in the longitudinal direction, thus realizing the longitudinal upward adjustment of the second door and window frame 9.

[0047] In summary, the door and window hinge structure of this application embodiment can simultaneously adjust the gap of the second door and window frame 9 in four directions (up, down, left, and right) without disassembling the door and window, which saves time and effort, is easy to operate, and has a high degree of flexibility.

[0048] Please continue to refer to this. Figure 2 The door and window hinge structure in this embodiment of the application also includes connecting screws 5 and washers 6. The hinge 1, the lateral adjustment component 3, and the connecting fastener 2 are all detachably connected by connecting screws 5 and washers 6. When making lateral or longitudinal adjustments, connecting screws 5 and washers 6 can be removed. For the specific form of the detachable connection between the hinge 1, the lateral adjustment component 3, the connecting fastener 2, and connecting screws 5 and washers 6, please refer to the description below.

[0049] The specific structure of the lateral adjustment component 3 and the lateral adjustment process are described in detail below with reference to the accompanying drawings.

[0050] Specifically, refer to Figure 2 The lateral adjustment assembly 3 includes a lateral adjustment member 31 and a lateral adjustment screw 32. The lateral adjustment member 31 includes a first lateral adjustment body 311 and a second lateral adjustment body 312 connected to each other. The first lateral adjustment body 311 is oriented longitudinally (e.g., ...). Figure 2 (As shown in the Z direction) downwards (e.g.) Figure 2 Extending in the direction shown in the middle n), the second lateral adjustment body 312 is disposed perpendicular to the first lateral adjustment body 311. For example, Figure 2 The lateral adjustment component 3 is shown to be in an inverted L shape, but this application does not limit the specific shape of the lateral adjustment component 3.

[0051] A first threaded hole 313 is provided on the second lateral adjustment body 312 to cooperate with the lateral adjustment screw 32; the lateral adjustment screw 32 that cooperates with the first threaded hole 313 is rotated to perform helical transmission. This application does not limit the thread parameters (such as pitch, lead, helix angle, etc.) and type of the lateral adjustment screw 32 and the first threaded hole 313. They can be selected according to the actual transmission requirements. High-efficiency transmission thread types such as trapezoidal thread or sawtooth thread can be used.

[0052] Continue to refer to Figure 2 The connecting fastener 2 includes a first part 21 and a second part 22 spaced apart. Exemplarily, both the first part 21 and the second part 22 are fixed to the second door / window frame 9, along the longitudinal direction (e.g., ...). Figure 2As shown in the Z direction, the first part 21 is located above the second part 22, and the second part 22 is vertically downward (as shown in the Z direction). Figure 2 Extending in the direction of n, the first part 21 and the second part 22 are spaced apart to form an active space S.

[0053] In the door and window hinge structure of this application embodiment, the second lateral adjustment body 312 is located in the activity space S when it is in the non-adjustment or adjustment state. For example, the longitudinal height of the activity space S is at least greater than the sum of the longitudinal heights of the second lateral adjustment body 312 and the lateral adjustment screw 32 nut, so as to ensure that the second lateral adjustment body 312 can move up and down longitudinally in the activity space S through the lateral adjustment screw 32.

[0054] A through hole 211 is provided on the first part 21 corresponding to the lateral adjustment screw 32. When performing lateral adjustment, for example, a wrench or other tool is used to rotate the lateral adjustment screw 32 located at the lower end of the first part 21 by passing through the through hole 211. For example, along... Figure 2 Rotating in direction B as shown, the lateral adjusting screw 32 engages with the first threaded hole 313 to perform the aforementioned helical transmission, thereby driving the first lateral adjusting body 311 longitudinally upward (as shown). Figure 2 (as shown in the middle m direction). Simultaneously, the first lateral adjustment body 311 and the second part 22 are also connected by an inclined plane, so that when the first lateral adjustment body 311 moves longitudinally upwards, it drives the second part 22, which is fixedly connected to the second door / window frame 9, to move laterally (as shown in the middle m direction). Figure 2 (as shown in the Y direction) to the right (e.g.) Figure 2 The movement (as shown in the p direction) is used to achieve the lateral rightward adjustment of the second door and window frame 9.

[0055] Furthermore, using a wrench or similar tool, passing through the through hole 211, the aforementioned transverse adjusting screw 32 is adjusted as follows: Figure 2 Rotating in the opposite direction to direction B, the lateral adjusting screw 32 engages with the first threaded hole 313 for helical transmission, thereby driving the first lateral adjusting body 311 along the longitudinal direction (e.g., Figure 2 (As shown in the Z direction) downwards (e.g.) Figure 2 As shown in the n-direction, the first lateral adjustment body 311 moves longitudinally downwards, while simultaneously, through the inclined surface cooperation between the first lateral adjustment body 311 and the second part 22, the first lateral adjustment body 311 drives the second part 22, which is fixedly connected to the second door and window frame 9, to move laterally (as shown in the n-direction). Figure 2 (as shown in the Y direction) to the left (e.g.) Figure 2 The movement (as shown in the middle o direction) is used to achieve the horizontal leftward adjustment of the second door and window frame 9.

[0056] It should be noted that the aforementioned inclined plane not only drives the second part 22 to move left and right in the lateral direction, but also limits the first lateral adjustment body 311, so that the first lateral adjustment body 311 moves only up and down in the longitudinal direction after being driven by the helical transmission of the lateral adjustment screw 32 and the first threaded hole 313, and not in other directions, thereby facilitating the driving of the second part 22 to move left and right in the lateral direction.

[0057] For example, the through hole 211 can be formed as a U-shaped hole, an elongated hole, etc. to facilitate the passage of tooling, but there is no limitation on the shape of the through hole 211, which can be selected according to the actual rotation requirements.

[0058] Continue to refer to Figure 2 and combined Figure 1 Furthermore, when the first lateral adjustment body 311 moves longitudinally upward through the lateral adjustment screw 32 that engages with the first threaded hole 313, due to the inclined surface engagement, the second part 22 moves laterally away from the first lateral adjustment body 311. Therefore, the second door and window frame 9, which is fixedly connected to the second part 22, also moves laterally away from the first lateral adjustment body 311, thereby realizing the lateral rightward adjustment of the second door and window frame 9, thereby increasing the lateral gap G of the door and window sash installed on the second door and window frame 9.

[0059] When the first lateral adjustment body 311 moves downward longitudinally, the second part 22 moves laterally toward the first lateral adjustment body 311, and the second door / window frame 9 also moves laterally toward the first lateral adjustment body 311 along with the second part 22, thereby realizing the lateral leftward adjustment of the second door / window frame 9. At this time, the lateral gap G of the door / window sash installed on the second door / window frame 9 is reduced accordingly. This further realizes the lateral left-right adjustment of the door / window sash gap. For details of the above-described bevel fitting process, please refer to [reference needed]. Figure 4a and 4b and combined Figure 1 As shown, a slanted protrusion 314 is provided on the side of the first lateral adjustment body 311 facing the second part 22, and a slanted groove 221 is provided on the side of the second part 22 facing the first lateral adjustment body 311. As the first lateral adjustment body 311 moves upward longitudinally, the slanted protrusion 314 exerts a rightward squeezing force on the slanted groove 221. Since the second part 22 with the slanted groove 221 is fixed to the second door / window frame 9, the second part 22 drives the second door frame 9 to move laterally to the right, increasing the lateral gap G of the door / window sash. When the first lateral adjustment body 311 moves downward longitudinally, the slanted protrusion 314 gradually disengages from the squeezing state relative to the slanted groove 221. At this time, the second part 22 then resets laterally to the left, driving the second door frame 9 to move laterally to the left, decreasing the lateral gap G of the door / window sash.

[0060] Further reference Figure 4a and 4b and combined Figure 1 When the oblique protrusion 314 and the oblique groove 221 are fully engaged, it represents the extreme state of the lateral leftward adjustment of the second door / window frame 9. At this point, the lateral gap G of the door / window sash is minimized. For example, the initial adjustment state can be set to the oblique protrusion 314 and the oblique groove 221 being fully engaged. This represents the minimum lateral adjustment state of the door / window hinge structure in this embodiment, with the lateral gap being the minimum lateral gap Gmin (e.g., ...). Figure 5a and Figure 5b (As shown). However, there is no restriction on the degree of fit between the inclined protrusion 314 and the inclined groove 221 in the initial adjustment state. It is also possible that the inclined protrusion 314 and the inclined groove 221 are not completely fitted in the initial adjustment state. Since the hinge 1, the lateral adjustment component 3, and the connecting fastener 2 are all detachably connected, the door and window sash can be fixedly installed and the lateral left and right adjustment of the door and window sash gap can be achieved at the same time even when they are not completely fitted. As long as the door and window hinge structure is stable in the non-adjustment state and lateral left and right adjustment can be performed in the adjustment state, it is within the protection scope of this application.

[0061] Further reference Figure 4a and 4b and combined Figure 1 When the oblique protrusion 314 is furthest away from the oblique groove 221, it is the limit state of the second door and window frame 9's lateral rightward adjustment. At this time, the lateral gap G of the door and window sash increases to the maximum, which is the maximum lateral adjustment state of the door and window hinge structure in this embodiment of the application. The lateral gap is the maximum lateral gap Gmax (e.g., Figure 5c and Figure 5d (As shown).

[0062] It should be noted that the aforementioned oblique protrusion 314 can be triangular, rectangular, or trapezoidal. The door and window hinge structure of this application does not limit the shape of the oblique protrusion 314 and the oblique groove 221. As long as the oblique protrusion and oblique groove can satisfy the above-mentioned horizontal left and right adjustment, the helical transmission of the horizontal adjustment screw 32 and the first threaded hole 313, and play the role of limiting the movement only in the longitudinal direction, they are all within the protection scope of this application.

[0063] Continue to refer to Figure 4a and 4b The inclined protrusion 314 includes a first inclined surface 3141 and a first flat surface 3142, and the inclined groove 221 includes a second inclined surface 2211 and a second flat surface 2212.

[0064] and combined Figure 5a and Figure 5bFor example, in the initial state, the first plane 3142 of the inclined protrusion 314 and the second plane 2212 of the inclined groove 221 are in contact, the first inclined surface 3141 and the second inclined surface 2211 are in contact, and the contact area of ​​the inclined surface is the first contact area a1. At this time, the area of ​​the first contact area a1 is the largest and the lateral gap G is the smallest, which is the aforementioned minimum lateral adjustment state.

[0065] Combined Figure 5c and Figure 5d When the first plane 3142 and the second plane 2212 separate, the first inclined plane 3141 and the second inclined plane 2211 remain in contact. The contact area of ​​the inclined planes is the second contact area a2. The area of ​​the second contact area a2 can increase as the first lateral adjustment body 311 moves longitudinally downward. At this time, the second door and window frame 9 is adjusted laterally to the left, and the lateral gap G of the door and window sash decreases accordingly until... Figure 5a and Figure 5b The diagram shows the minimum lateral adjustment state. The area of ​​the second fitting region a2 will decrease further as the first lateral adjustment body 311 decreases longitudinally upwards. At this point, the second door / window frame 9 is adjusted laterally to the right, and the lateral gap G of the door / window sash increases to [value missing]. Figure 5d The maximum lateral adjustment state is shown.

[0066] The specific structure of the longitudinal adjustment component 4 and the longitudinal adjustment process will be explained in detail below.

[0067] In this embodiment, the longitudinal adjustment component 4 is used to cooperate with the hinge 1 to drive the connecting fastener 2 to move up and down in the longitudinal direction, so that the second door and window frame 9, which is fixed to the connecting fastener 2, moves up and down in the longitudinal direction.

[0068] For details, please refer to Figure 2 and Figure 6 The longitudinal adjustment assembly 4 includes a longitudinal adjustment screw 41 and a second threaded hole 42; the connecting fastener 2 also includes a bearing portion 23, which is connected to the second part 22 along the longitudinal direction (e.g., Figure 2 The lower end (as shown in the Z direction) is used to support hinge 1, and the support part 23 is along... Figure 2 The length along direction A shown is greater than the length of the second part 22 along that direction. For example... Figure 2 As shown, a second threaded hole 42 is provided on the portion of the first part 21 and the portion of the supporting part 23 that protrudes from the second part 22.

[0069] When longitudinal adjustment begins, the screw end of the longitudinal adjusting screw 41 abuts against the longitudinal end of the hinge 1. (Reference) Figure 1 and Figure 2 The bottom end of hinge 1 along the longitudinal direction is fitted with the bearing part 23, such as Figure 7a As shown, this is the minimum longitudinal adjustment state. Continue to refer to... Figure 2Using the workpiece to rotate the longitudinal adjusting screw 41, exemplarily, along... Figure 2 As shown, rotating in the E direction causes the longitudinal adjusting screw 41 to engage with the second threaded hole 42 for longitudinal helical transmission, thereby applying longitudinal force to the hinge 1 (e.g., Figure 2 (As shown in the Z direction) upwards (e.g.) Figure 2 The force (as shown in the m direction) is such that, since both hinge 1 and bearing part 23 are fixed longitudinally, bearing part 23 is longitudinally downward relative to hinge 1 (as shown in the m direction). Figure 2 The movement (as shown in the n-direction) drives the second door / window frame 9, which is fixedly connected to the support part 23, to move downwards longitudinally, as shown in the n-direction. Figure 7b As shown, this is the maximum longitudinal adjustment state, with the top of hinge 1 along the longitudinal direction fitting against the first part 21.

[0070] Continue to refer to Figure 1 and Figure 2 and combined Figure 7b For example, the longitudinal adjusting screw 41 is rotated in the opposite direction of the E direction using the workpiece. The longitudinal adjusting screw 41 engages with the second threaded hole 42 in the longitudinal direction (e.g., Figure 2 As shown in the Z direction, it moves downwards. Since hinge 1 is fixed longitudinally, the bearing part 23 moves upwards relative to hinge 1 longitudinally (as shown in the Z direction). Figure 2 The hinge 1 moves in the direction shown in m. At this time, the gap between the bottom end of the hinge 1 in the longitudinal direction and the top surface of the bearing part 23 decreases until it is reset to the minimum longitudinal adjustment state as shown in 7a, so that the second door and window frame 9 moves upward in the longitudinal direction.

[0071] The embodiments of this application do not limit the number of longitudinal adjusting screws 41. Figure 2 , Figure 7a and Figure 7b As shown, there is one longitudinal adjustment screw, but there can also be two. As long as they can work with the hinge 1 to drive the second door and window frame 9 to adjust vertically, they are all within the scope of protection of this application.

[0072] In one possible implementation, continue to refer to Figure 1 and Figure 2 The longitudinal adjusting screw 41 can also be provided as two, respectively engaging with the second threaded hole 42 of the bearing portion 23 and the second threaded hole 42 of the first portion 21. Exemplarily, along the E direction, rotating the longitudinal adjusting screw 41 of the bearing portion 23 engages with the second threaded hole 42, applying longitudinal (e.g., ...) force to the hinge 1. Figure 2 (As shown in the Z direction) upwards (e.g.) Figure 2 The force (as shown in the m direction) on the bearing part 23 relative to the hinge 1 in the longitudinal direction downward (as shown in the m direction) Figure 2 The movement (as shown in the n-direction) causes the second door / window frame 9 to move downwards longitudinally, thus achieving the desired downward movement of the second door / window frame 9. Figure 7b The state shown.

[0073] At this time, the longitudinal adjusting screw 41 of the first part 21 can be rotated in the E direction to move it downward in the longitudinal direction, applying a downward force to the top of the hinge 1 in the longitudinal direction, causing the first part 21 to move upward in the longitudinal direction relative to the hinge 1, thereby driving the second door and window frame 9 to move upward in the longitudinal direction; at the same time, the longitudinal adjusting screw of the bearing part 23 is rotated in the opposite direction of the E direction, and the specific movement process is as described in the first embodiment above. Thus, the two longitudinal adjusting screws 41 of the bearing part 23 and the first part 21 can simultaneously drive the second door and window frame 9 to move upward in the longitudinal direction.

[0074] Further, please refer to Figure 2 and Figure 6 The hinge 1 includes a bent portion 11, which is located longitudinally (e.g., Figure 2 (As shown in the Z-direction) Extends and is located between the support portion 23 and the first portion 21. More specifically, the bent portion 11 is longitudinally parallel to the side of the second portion 22, and the nut of the longitudinal adjusting screw 41 is located on the bottom surface of the support portion 23 and / or the top surface of the first portion 21. For example, as shown in the Z-direction. Figure 6 As shown, the screw end of the longitudinal adjusting screw 41 passes through the second threaded hole 42 and abuts against the longitudinal end of the bent portion 11. By rotating the workpiece, the longitudinal adjusting screw 41 engages with the second threaded hole 42 to perform helical drive, thereby applying longitudinal pressure (e.g., ...) to the bent portion 11. Figure 2 The upward and downward forces (as shown in the Z direction) cause the bearing portion 23 or the first portion 21, which is against the end of the bent portion 11, to move the first portion 21 or the bearing portion 23 downward and upward relative to the bent portion 11 in the longitudinal direction, thereby driving the second door and window frame 9, which is fixedly connected to the first portion 21 or the bearing portion 23, to move upward and downward in the longitudinal direction.

[0075] Please refer to Figure 2 and combined Figure 1 The hinge 1 also includes a hinge portion 12 and a connecting portion 13. One end of the hinge portion 12 along the longitudinal direction is used to hinge with the first door / window frame 8, and the other end is connected to the connecting portion 13 along the longitudinal direction (e.g., Figure 2 The hinge 1 is connected to one end of the connecting part 13 (as shown in the Z direction). The bent portion 11 is perpendicularly disposed at the other end of the connecting part 13 along the longitudinal direction. The bent portion 11 is perpendicular to the side of the connecting part 13 facing the connecting fastener 2 and is disposed perpendicular to the other end of the connecting part 13 along the longitudinal direction. The hinge 1 also includes a first fixing seat 14 located at the upper and lower ends of the hinge part 12 along the longitudinal direction. A first fixing hole 141 is opened on the first fixing seat 14, and the hinge 1 and the first door and window frame 8 are fixedly connected by fastening screws. The embodiments of this application do not limit the number and shape of the first fixing hole 141. As long as the fixed connection between the first fixing seat 14 and the first door and window frame 8 can be achieved, it is within the protection scope of this application.

[0076] Continue to refer to Figure 2 and combined Figure 1 The connecting fastener 2 also includes a second fixing seat 24, the second fixing seat 24 being along the longitudinal direction (e.g., Figure 2 (As shown in the Z direction) Extends along the sides of the first part 21, the second part 22, and the support part 23, and along the longitudinal direction, the side of the second fixing seat 24 is sequentially fixedly connected to the first part 21, the second part 22, and the support part 23. A second fixing hole 241 is provided on the second fixing seat 24 so that the second fixing seat 24 and the second door and window frame 9 are fixed by fastening screws, that is, the connecting fastener 2 is fixed to the second door and window frame 9 as a whole.

[0077] In one possible implementation, continue to refer to Figure 2 The aforementioned detachable connection via connecting screw 5 and washer 6 is specifically achieved by opening connecting holes 7 on the longitudinally extending surfaces of connecting part 13, first lateral adjustment body 311, and second part 22. Washer 6 is fitted onto connecting screw 5 and adheres to the side surface of connecting part 13 facing away from first lateral adjustment body 311. Connecting screw 5 and washer 6 are inserted into connecting hole 7 to achieve detachable connection of hinge 1, lateral adjustment component 3, and connecting fastener 2 in sequence along the lateral direction.

[0078] Figure 2 As shown in the figure, there are 3 connecting holes 7. However, the number and shape of the connecting holes 7 are not limited in this application embodiment. There can be 1, 2 or more, and they can be circular holes, elongated holes, U-shaped holes, etc. As long as the hinge 1, the lateral adjustment component 3 and the connecting fastener 2 can be detachably connected in the lateral direction in sequence by using the connecting screw 5 and the washer 6, they are all within the protection scope of this application.

[0079] In one possible implementation, the connecting hole 7 of the connecting portion 13 and the first lateral adjustment body 311 may be an elongated hole to facilitate the bearing of the connecting screw 5 and the washer 6 when the connecting screw 5 and the washer 6 are loosened for longitudinal adjustment.

[0080] Continue to refer to Figure 2 A longitudinal adjustment mark line L1 is provided on the surface of the second fixed seat 24 on the side closer to the first part 21 in the A direction and on the surface of the movable space S in the Z direction. The longitudinal adjustment mark line L1 is parallel to the... Figure 2 As shown in direction A, during longitudinal adjustment, the bending portion 11 can be observed relative to the longitudinal direction (e.g., direction A). Figure 2 The upper end (along the Z-direction) Figure 2The adjustment amount is obtained by using the end face (shown in the m direction) and the longitudinal adjustment mark line L1, making the longitudinal vertical adjustment of the door and window hinge structure of this embodiment more accurate; a lateral adjustment mark line L2 is set on the surface of the second fixed seat 24 at the connection with the bearing seat 23, and when making lateral adjustment, the adjustment is obtained by observing the bending part 11 relative to the longitudinal direction (e.g., one end in the m direction). Figure 2 The lower end (along the Z-direction) Figure 2 The end face (shown in the n direction) and the lateral adjustment mark line L2 are used to obtain the adjustment amount, so that the lateral left and right adjustment of the door and window hinge structure in this embodiment of the application is more accurate.
