Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] 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.

[0034] 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.

[0035] Example 1

[0036] like Figure 1 As shown, this embodiment provides a door and window system, including a frame 5, a door leaf, a hinge 7, and a door and window gap adjustment mechanism. This embodiment also provides a door and window gap adjustment mechanism, including a support 1 and a connecting component 2. The support 1 is used to fix itself to the frame 5 and has a suspension part. The connecting component 2 is used to fix itself to the door leaf via the hinge 7. The connecting component 2 includes a crossbeam 22, which can be suspended from the suspension part, thereby suspending the door leaf from the frame 5.

[0037] Among them, "doors and windows" is a general term for doors and windows.

[0038] The support 1 has mounting holes 14, and the frame 5 has fixing holes. Fasteners 4 pass through the mounting holes 14 and fixing holes and are fixedly connected to the fixing holes to fix the support 1 to the frame 5. For example, the support 1 has two mounting holes 14 in the horizontal direction, and the fasteners 4 are screws. The two screws pass through the two mounting holes 14 and the two fixing holes respectively. The screws engage with the internal threads of the fixing holes to connect with the frame 5, thereby enabling the support 1 to be installed on the frame 5, which is convenient for assembly.

[0039] The suspension part is a suspension groove 12. The opening of the suspension groove 12 is away from the door leaf. The crossbeam 22 can pass through the opening to be suspended in the suspension groove 12, which facilitates the installation between the crossbeam 22 and the support 1.

[0040] The connecting assembly 2 also includes a mounting base 21, which is used to fix the door leaf to the hinge 7. The mounting base 21 is connected to the crossbeam 22, so that the door leaf is suspended from the frame 5 in sequence by the hinge 7, the mounting base 21 and the crossbeam 22. The crossbeam 22 can adjust the movement of the mounting base 21 relative to the support 1, thereby moving the door leaf relative to the frame 5 and adjusting the gap between the door leaf and the frame 5.

[0041] The mounting base 21 includes a through hole 211 with internal threads, and a crossbeam 22 has external threads 221. The crossbeam 22 passes through the through hole 211, and the external threads 221 and internal threads are threadedly connected. The crossbeam 22 rotates relative to the suspension part to move the mounting base 21 relative to the support 1. For example, a hexagonal groove is provided at the end of the crossbeam 22. By using a hexagonal wrench to tighten the crossbeam 22, the mounting base 21 can move on the crossbeam 22, that is, move relative to the mounting base 21. This is convenient to operate, has a simple structure, and is easy to implement. Furthermore, the threaded connection allows for high adjustment accuracy.

[0042] The connecting assembly 2 also includes a locking member. The mounting base 21 has a locking hole communicating with the through hole 211. The locking member passes through the locking hole to lock the crossbeam 22. This ensures that the crossbeam 22 is stably installed within the mounting base 21, guaranteeing installation stability and reliability. For example, the locking member is a tapered nut screw with an internal thread in the locking hole. The tapered nut screw is threaded into the locking hole, and its end facing the crossbeam 22 is pressed against the crossbeam 22 to achieve locking, preventing the crossbeam 22 from moving left or right and affecting the installation effect.

[0043] In this embodiment, the support 1 is installed on the upper frame profile of the frame 5 as an example for illustrative purposes. The crossbeam 22 enables the mounting base 21 to move horizontally (left or right) relative to the support 1, thereby allowing the door leaf to move horizontally (left or right) relative to the frame 5. In other embodiments, the support 1 can also be installed on the lower frame profile of the frame 5, or two door / window gap adjustment mechanisms can be provided simultaneously, with the two supports 1 respectively located on the upper and lower frame profiles. Optionally, the crossbeam 22 can be at a slight angle to the horizontal direction to adapt to different door and window systems and increase its applicability.

[0044] like Figures 1-4 As shown, optionally, the door and window system is assembled using the aforementioned door and window gap adjustment mechanism, and the steps include:

[0045] S100 and support 1 are fixed to the upper frame profile by self-tapping screws at both ends.

[0046] S200, mounting base 21 and crossbeam 22 are connected by threads, and then the tapered nut screw and locking hole 212 are threaded together to lock the crossbeam 22.

[0047] S300. At the assembly site, fix the connecting component 2, hinge 7, and door leaf together, that is, the hinge 7 connects the connecting component 2 and the door leaf to form a structure as shown in the figure. Figure 3 The structure shown.

[0048] S400, The door leaf is directly suspended in the hanging groove 12 of the support 1 via the crossbeam 22 of the connecting component 2, thus completing the installation and forming a shape as shown. Figure 4 The structure shown.

[0049] S500. Adjustment is performed with the door closed. First, loosen the tapered nut screws. Then, by turning the crossbeam 22, move the door left and right to adjust the left and right gaps. While adjusting, observe whether the gaps are uniform. Once the desired position is reached, tighten the tapered nut screws. The door and mounting base 21 are suspended from the support 1 via the crossbeam 22 and then installed on the frame 5.

[0050] At the assembly site, support 1 is fixed to frame 5, and mounting bracket 21 in connecting component 2 is fixed to the door leaf. Workers can suspend the crossbeam 22 from support 1, achieving rapid installation between the door leaf and frame 5. This makes installation easier for workers and avoids difficulties under load, theoretically allowing for single-person installation. When adjusting the gap, on the one hand, by operating the crossbeam 22, such as driving the crossbeam 22 to rotate, the door leaf can be moved left or right to adjust the gap, which is simple to operate. On the other hand, compared to existing technologies where hinge 7 can only be adjusted when the door leaf is open, and then the door leaf needs to be closed to confirm whether the adjustment is in place, and sometimes even requires repeated adjustments, this solution allows adjustment when the door leaf is closed. During adjustment, the uniformity of the door leaf gap can be observed at any time, eliminating the need for repeated opening and closing of the door leaf for adjustment. This allows for faster confirmation of whether the adjustment is in place, improving the product's adjustment efficiency and avoiding the tedious and complex adjustment, alignment, and assembly problems associated with hinge 7, thereby improving the installation efficiency of the door and window system.

[0051] Optionally, door panels can be fitted with corner protectors to enhance the sealing at the corners, which is especially suitable for situations where the door panel adjustment range is small.

[0052] Both the support 1 and the mounting base 21 are installed on the same side of the door and window system, either on the inside or the outside, with the crossbeam 22 suspended from the support 1. Operating the crossbeam 22 is not affected by the operating space, increasing the adjustable range of the door leaf, reducing the precision requirements for door leaf manufacturing and installation, lowering costs, and further improving installation efficiency. In folding door installation, assembly using existing methods typically takes one hour, but using the door and window gap adjustment mechanism reduces it to about ten minutes, significantly improving installation efficiency. The aforementioned door and window system can be either hinged or folding doors, and the door and window gap adjustment mechanism has a wide range of applications.

[0053] In one embodiment, the support 1 includes a recess 11, and the mounting base 21 can be embedded in the recess 11. An adjustment gap exists between the recess 11 and the mounting base 21. Increasing the adjustment gap appropriately increases the adjustable range of the door leaf. Compared to adjusting the door gap on the hinge 7, the traditional adjustment range is 0-3mm. In this solution, a larger adjustment range can be achieved through the adjustment between the crossbeam 22 and the mounting base 21, currently ±6mm.

[0054] The support 1 has two protrusions 15, forming an inlay groove 11 between them. Each protrusion 15 has a corresponding suspension part, and the two ends of the crossbeam 22 are suspended from the two suspension parts. That is, the suspension groove 12 is opened in the protrusion 15, and the crossbeam 22 is suspended in the suspension groove 12 located on both sides of the mounting base 21. The two ends of the crossbeam 22 are supported in the suspension groove 12, so that the crossbeam 22 is evenly stressed and can withstand greater bending moment and shear force, thereby better bearing the weight of the door leaf.

[0055] During assembly, in step S200, the mounting base 21 is adjusted to the middle position of the crossbeam 22, and then locked in place. With the mounting base 21 in the middle position, both ends of the crossbeam 22 are exposed for suspension within the suspension groove 12. Adjustments can be made left or right as needed to minimize movement.

[0056] In other embodiments, the mounting base 21 can be located on one side of the support 1, and the mounting base 21 is suspended from one end of the crossbeam 22 that extends out of the suspension groove 12, thereby having a larger adjustment space.

[0057] In this embodiment, the mounting base 21 and the hinge 7 are separate structures. One end of the mounting base 21 is embedded in the mounting groove 11, and the other end is provided with a mounting head for connecting to the hinge 7. The hinge 7 includes a hinge plate and a hinge shaft 71 rotatably connected to the hinge plate. The hinge shaft 71 is connected to a connecting hole on the mounting head. Specifically, the two can be connected by a detachable connection method such as plug-in, threaded connection, or snap-fit. Furthermore, the mounting head also has a first locking hole communicating with the connecting hole. A locking screw 8 is connected to the first locking hole, with one end pressing against the hinge shaft 71 to further fix the hinge shaft 71. Furthermore, the mounting head is also provided with an outer cover 9. The shape of the outer cover 9 is adapted to the mounting head to improve aesthetics. The outer cover 9 has a second locking hole. The locking screw 8 is connected to both the first and second locking holes. By providing the second locking hole, the length of the first locking hole is extended, ensuring the reliability of the connection of the locking screw 8 to the first locking hole. Furthermore, two locking screws 8 and two first locking holes are provided, with the two locking screws 8 correspondingly connected to the two first locking holes, which improves the reliability of locking the hinge shaft 71.

[0058] In other embodiments, the mounting base 21 and the hinge 7 can be connected by means such as welding, or the mounting base 21 and the hinge 7 can be an integral structure, that is, the hinge shaft 71 and the mounting base 21 are welded or integrally connected, and the hinge 7 and the door and window gap adjustment mechanism are used as a set.

[0059] Example 2

[0060] like Figure 5As shown, this embodiment provides a door and window gap adjustment mechanism and a door and window system including the mechanism. The structure of this embodiment is basically the same as that of Embodiment 1, and the similar parts will not be described again. The difference is that the support 1 has three mounting holes 14 in the horizontal direction, and the fastener 4 is a self-tapping screw. The three self-tapping screws pass through the three mounting holes 14 and are connected to the frame 5, which is convenient for assembly. By increasing the number of self-tapping screws and mounting holes 14, the connection reliability between the support 1 and the frame 5 is improved, and the door leaf is prevented from falling off.

[0061] The assembly of the door and window system using the above-mentioned door and window gap adjustment mechanism is basically the same as the assembly steps in Embodiment 1. The difference is that after step S400, it further includes: fixing the mounting hole 14 in the middle position of the support 1 to the upper frame profile with self-tapping screws to achieve complete fixation of the support 1.

[0062] The connecting assembly 2 also includes a locking member 23. The mounting base 21 has a locking hole 212 communicating with the through hole 211. The locking member 23 passes through the locking hole 212 to lock the crossbeam 22. This ensures that the crossbeam 22 is stably installed in the mounting base 21, guaranteeing installation stability and reliability. For example, the locking member 23 is a tapered nut screw. The locking hole 212 has internal threads. The tapered nut screw is threadedly connected to the locking hole 212, and its end facing the crossbeam 22 presses against the crossbeam 22 to achieve locking, preventing the crossbeam 22 from moving left or right and affecting the installation effect.

[0063] Example 3

[0064] like Figure 6 and Figure 7 As shown, this embodiment provides a door and window gap adjustment mechanism and a door and window system including the mechanism. The structure of this embodiment is basically the same as that of Embodiments 1 and 2, and the similar parts will not be described again. The difference is that: the side of the frame 5 is connected to the adjustment profile 6, and the door and window gap adjustment mechanism also includes a locking component 3. The locking component 3 includes a shaped locking block 31 and a locking rod 32. The locking rod 32 is parallel to the crossbeam 22. The shaped locking block 31 is connected to the mounting base 21 through the locking rod 32. The shaped locking block 31 is used to engage with the mounting groove 61 of the adjustment profile 6 on the frame 5 to drive the adjustment profile 6 to adjust its position synchronously. For example, the shaped locking block 31 is long and has protrusions at both ends along its length. By rotating the angle of the shaped locking block 31, when its two sides in the width direction face the groove sidewall of the mounting groove 61, it can enter from the groove opening of the mounting groove 61. After rotation, its protrusions lock when they touch the groove sidewall of the mounting groove 61.

[0065] By setting up locking component 3 and adjusting profile 6, the adjusting profile 6 is connected to the door leaf through the locking component and mounting base 21. When the door leaf moves, the adjusting profile 6 moves synchronously. The compression of the sealing strip between the adjusting profile 6 and the door leaf remains constant, ensuring good sealing performance. This avoids the problem of excessive gaps between the frame and the door leaf caused by the accumulation of errors such as door leaf production errors, installation errors, and errors caused by door leaf adjustment, which can easily lead to insufficient compression of the sealing strip and a decrease in the sealing performance between the frame and the door leaf. In other words, it solves the problem of water leakage caused by the increased gap between the door leaf and the frame 5 after the door leaf is adjusted. It is more suitable for folding doors that require a larger adjustment range. By adding adjusting profile 6, the gaps in the door leaf are improved, and the airtightness is enhanced.

[0066] Optionally, the locking rod 32 is a screw, and the irregularly shaped locking block 31 is threadedly connected to the locking rod 32. The mounting base 21 has a threaded hole 213, through which the locking rod 32 passes and is threadedly connected. Optionally, the locking assembly 3 also includes a connecting seat 33, which is detachably connected to the mounting base 21, and the locking rod 32 is connected to the connecting seat 33. The locking rod 32 is connected to the connecting seat 33, meaning the locking rod 32 is connected to the mounting base 21 via the connecting seat 33, replacing the direct connection of the locking rod 32 to the mounting base 21. Optionally, both of the above solutions can be provided simultaneously, allowing for selective installation according to requirements. Optionally, the connecting seat 33 can be connected to the mounting base 21 via screws or snap-fit ​​connections.

[0067] Optionally, one or more sets of locking components 3 can be provided. By increasing the number of locking components 3, the installation stability and reliability of the adjustable profile 6 can be improved. When multiple sets of locking components 3 are provided, the connecting seat 33 can be an integral structure or a split structure.

[0068] The assembly steps are basically the same as those in Embodiment 1 and Embodiment 2. The difference is that between steps S300 and S400, the following is also included: connecting the adjusting profile 6 to the irregular locking block 31, selecting the appropriate adjusting profile 6 according to the requirements, and locking it through the locking rod 32 and the irregular locking block 31 to make the door gap more uniform.

[0069] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
