[0002] In related technologies, door panels and frames are connected by hinges, which include frame hinge pieces and panel hinge pieces. During installation, one method requires first installing two hinge pieces onto the frame and door panel respectively, then connecting the two hinge pieces to achieve the connection between the door panel and frame. Another method requires first assembling two hinge pieces, then installing the hinge onto one of the door panel or frame, and finally installing the hinge onto the other. Both of these installation methods are prone to misalignment of the upper and lower hinges, uneven force on the hinges, etc., requiring repeated adjustments. However, hinges become difficult to install and adjust under load, often requiring multiple people working together, resulting in low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a hinge installation structure and door and window system that reduces installation difficulty and improves installation efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A hinge installation structure, comprising:

[0006] Support assembly for fixing to the bottom edge of the frame;

[0007] The connecting assembly includes a second connector and a hinge connected to each other. The second connector can be inserted vertically into the support assembly, and the hinge is used to fix the door leaf so that the door leaf is supported by the lower frame.

[0008] In some possible implementations, the support assembly includes a base, a first connector, and a slider slidably connected to the base in a horizontal direction. The connector is inserted into the slider. The base is used to connect to the lower edge of the frame. The first connector is capable of driving the slider to move, so that the slider causes the connector to move relative to the base.

[0009] In some possible implementations, the first connector includes a rod having a first external thread, the slider having a threaded connection hole, the rod passing through the threaded connection hole in a horizontal direction, and the first external thread and the threaded connection hole being threadedly connected, the first connector being horizontally confined to the base, and the first connector being rotatable to move the slider.

[0010] In some possible implementations, the second connector has a first connecting portion, the slider has a second connecting portion, and the first connecting portion and the second connecting portion are connected by a first locking member so that the second connecting portion is connected to the slider.

[0011] In some possible implementations, the base is provided with a horizontally extending groove, and the slider is slidably connected to the groove.

[0012] In some possible implementations, the slide is provided with a limiting groove on one side along the horizontal direction, and the limiting groove is provided with a first clearance opening and a second clearance opening at both ends along the horizontal direction. The first connecting member includes a limiting block provided at one end of the rod, the limiting block being limited in the limiting groove, and the rod passing through the first clearance opening and connected to the slider.

[0013] In some possible implementations, the tops of the chute and the limiting groove are both open, and the first connector can pass through the top opening to be disposed within the limiting groove and the first clearance opening; the slider can pass through the top opening to be disposed within the chute.

[0014] In some possible implementations, the connecting assembly further includes a pivot, the hinge and the pivot are rotatably connected, one end of the pivot extends out of the hinge and is threadedly connected to the second connector.

[0015] In some possible implementations, the base is connected to the lower frame via a second locking element.

[0016] A door and window system includes a frame, a door leaf, and a hinge mounting structure as described in any of the preceding claims. A support assembly is fixed to the lower edge of the frame, and a connecting assembly is fixed to the door leaf. A first connector of the support assembly and a second connector of the connecting assembly are inserted vertically to allow the door leaf to be supported by the lower edge.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a hinge installation structure and door / window system. Through connecting components and support components, the door leaf is supported by the frame, which bears the weight of the door leaf. This avoids the need for installation and adjustment after the hinge is loaded, reducing the number of workers required for installation and making it more convenient. Since the second connecting piece and the support component are plugged in, they automatically adapt to installation errors between the hinge and the door leaf without adjustment, reducing the accuracy requirements for door leaf installation and improving the vertical adjustment efficiency of the door leaf and frame. Furthermore, because the second connecting piece and the support component are plugged in vertically, compared to threaded connections, the plug-in connection has a certain degree of tolerance in practical applications. When the vertical position of the door leaf needs to be adjusted, the second connecting piece can move simultaneously with the door leaf, and the second connecting piece and the support component adapt to each other, still able to plug into each other. Therefore, the door leaf position adjustment is more flexible. Through these aspects, the installation difficulty of the door leaf is reduced and the installation efficiency is improved.

[0032] Example 1

[0033] like Figures 1-3As shown, this embodiment provides a door and window system, including a frame, a door leaf 200, and a hinge mounting structure. This embodiment provides a hinge mounting structure, including a support assembly 1 and a connecting assembly 2. The support assembly 1 is used to fix the door leaf 200 to the lower frame 100 of the frame. The connecting assembly 2 includes a second connector 21 and a hinge 23. The second connector 21 can be inserted vertically into the support assembly 1, and the hinge 23 is used to fix the door leaf 200, so that the door leaf 200 is connected to the support assembly 1 through the connecting assembly 2 and is supported by the lower frame 100. Here, "door and window" is a general term for both doors and windows.

[0034] When the door and window system uses the above-described hinge installation structure, its assembly includes the following steps: First, the support assembly 1 is fixed to the lower frame 100, and the second connector 21 is vertically inserted into the first connector 11, so that the connecting assembly 2 and the support assembly 1 are connected. The upper hinge of the door leaf 200 is then fixed to the frame. Afterwards, the door leaf 200 is connected to the hinge 23 of the connecting assembly 2, so that the door leaf 200 is connected to the lower frame 100 through the support assembly 1 and the connecting assembly 2, thereby completing the installation of the door leaf 200 and the frame.

[0035] By connecting component 2 and support component 1, the door leaf 200 is supported on the frame, which bears the weight of the door leaf 200. This avoids the need for installation and adjustment of the hinge 23 after it has been loaded with weight, reducing the number of workers required for installation and making the process more convenient. Since the second connector 21 and support component 1 are plugged in, they automatically adapt to the installation errors of the hinge 23 and door leaf 200 without adjustment, reducing the installation accuracy requirements of the door leaf 200 and improving the vertical adjustment efficiency of the door leaf 200 and the frame. Furthermore, because the second connector 21 and support component 1 are plugged in, when the vertical position of the door leaf 200 needs to be adjusted, the second connector 21 can move simultaneously with the door leaf 200, and the second connector 21 and the first connector 11 adaptably cooperate. Through these aspects, the installation difficulty of the door leaf 200 is reduced and the installation efficiency is improved.

[0036] The support assembly 1 also includes a base 12, a first connector 11, and a slider 14 slidably connected to the base 12 in a horizontal direction. The base 12 is used to connect to the lower frame 100 of the frame. Optionally, the base 12 is connected to the lower frame 100 by a second fastener. Exemplarily, the base 12 is elongated and is placed in the mounting groove 110 of the lower frame 100. The base 12 has mounting holes 124. The second fastener is such as an auto-tapping screw. During on-site assembly, the base 12 is placed in a preset position, and the self-tapping screw passes through the mounting hole 124 and connects to the lower frame 100, thereby achieving the installation and fixation of the base 12.

[0037] The connecting component 2 is inserted into the slider 14, and the base 12 is used to connect to the lower frame 100 of the frame. The first connecting member 11 can drive the slider 14 to move, so that the slider 14 drives the connecting component 2 to move relative to the base 12. In one embodiment, the first connecting member 11 includes a rod with a first external thread 113. The slider 14 is provided with a threaded connection hole 141. The rod passes through the threaded connection hole 141 in a horizontal direction, and the first external thread 113 and the threaded connection hole 141 are threadedly connected. The first connecting member 11 is limited to the base 12 in a horizontal direction, and the first connecting member 11 can rotate to move the slider 14.

[0038] With the door 200 open, rotating the first connecting member 11 causes the slider 14 to slide relative to it, as the first connecting member 11 is limited. Therefore, the slider 14 moves relative to the first connecting member 11 due to the threaded action between them. Since the first connecting member 11 and the slider 14 are plugged in and relatively fixed, the slider 14 moves the door 200 via the first connecting member 11, thus adjusting the position of the door 200. During adjustment, observe the change in the gap between the door 200 and the side frame; stop adjusting when the desired position is reached.

[0039] The base 12 is provided with a horizontally extending groove 125, and the slider 14 is slidably connected to the groove 125 to ensure the movement accuracy of the slider 14 relative to the base 12, thereby ensuring the movement accuracy of the door leaf 200.

[0040] Furthermore, the second connector 21 is provided with a first connecting portion 215, and the slider 14 is provided with a second connecting portion 143. The first connecting portion 215 and the second connecting portion 143 are connected by a first fastener 15, so that the second connecting portion 143 is connected to the slider 14, increasing the connection strength and ensuring the reliability of the connection between the slider 14 and the door leaf 200, thereby ensuring that the door leaf 200 moves simultaneously with the slider 14. The first fastener 15 is such as a screw. The first connecting portion 215 is provided with a countersunk hole, etc., and the second connecting portion 143 is provided with a threaded hole. The screw passes through the hole of the first connecting portion 215 and the threaded hole of the second connecting portion 143, and then is threadedly connected to the threaded hole, thereby realizing the connection between the first connecting portion 215 and the second connecting portion 143. When space is limited, the first fastener 15, the first connecting portion 215, and the second connecting portion 143 and other related structures can be omitted to prevent structural interference and simplify the structure.

[0041] In one embodiment, the slider 14 is provided with two second connecting portions 143, and the second connector 21 is provided with two first connecting portions 215, further improving the connection reliability between the slider 14 and the door leaf 200. A insertion groove 142 is formed between the two second connecting portions 143, and an insertion block 216 is formed between the two first connecting portions 215. The insertion block 216 has a protruding ridge 2161 along the extending direction of the slide groove 125. The ridge 2161 increases the contact area between the insertion block 216 and the insertion groove 142, improving connection reliability. Furthermore, the ridge 2161 limits the movement of the insertion groove 142 and the insertion block 216 along the width direction of the slide groove 125, ensuring installation accuracy.

[0042] A limiting groove 126 is provided on one side of the slide groove 125 along the horizontal direction. The limiting groove 126 has a first clearance opening 1261 and a second clearance opening 1262 at its two ends along the horizontal direction. The first connecting member 11 includes a limiting block at one end of the rod portion, which limits the limiting groove 126. The rod portion passes through the first clearance opening 1261 and connects to the slider 14, thus achieving horizontal limiting of the limiting groove 126. The structure is simple. Furthermore, the tops of both the slide groove 125 and the limiting groove 126 are open, allowing the first connecting member 11 to pass through the top opening and be disposed within the limiting groove 126 and the first clearance opening 1261; the slider 14 can also pass through the top opening and be disposed within the slide groove 125. For example, the first connecting member 11 is a bolt, where the head of the bolt forms a limiting block, and the bolt shank forms a rod portion for connection with the threaded connection hole 141. During assembly, the slider 14 is connected to the bolt's screw. Then, the slider 14 and the first bolt are installed together from the open end to the preset position. The screw passes through the first clearance opening 1261, and the head of the bolt is located in the limiting groove 126, making assembly convenient. The second clearance opening 1262 is used to allow tools such as wrenches to pass through. The tool passes through the second clearance opening 1262 to drive the head to rotate, that is, to drive the bolt to rotate, thereby realizing the movement of the slider 14.

[0043] The connecting assembly 2 also includes a pivot 22, a hinge 23, and a pivot 22 rotatably connected to the pivot 22. One end of the pivot 22 is an extension end 223 extending out of the hinge 23, and the extension end 223 is threadedly connected to the second connecting member 21. The hinge 23 can move up and down along the extension direction of the pivot 22, i.e., the vertical direction. When the door leaf 200 needs to move up and down or adjust its position in the vertical direction, this can be achieved by moving the extension end 223 relative to the second connecting member 21.

[0044] Example 2

[0045] like Figure 4As shown, this embodiment provides a door and window system and hinge installation structure, which is basically the same as the structure of Embodiment 1, except that: the first connector 11 is rod-shaped, and one end of the first connector 11 is provided with a plug 111. The second connector 21 has a slot 211 with its opening facing downwards, and the slot 211 and the plug 111 are inserted into each other. A limiting stop is provided in the slot 211, which can limit the axial movement of the plug 111 along the first connector 11, thereby limiting the relative movement between the door leaf 200 and the first connector 11 and keeping them relatively fixed.

[0046] The base 12 has a receiving groove 122. The base 12 has a threaded hole (not shown in the figure), and the first connector 11 has a first external thread 113. The first connector 11 passes through the threaded hole and is threadedly connected to the threaded hole through the first external thread 113. On the one hand, the connection between the first connector 11 and the base 12 is realized. On the other hand, the first connector 11 is driven to rotate, so that the first connector 11 moves horizontally relative to the base 12, thereby enabling the door leaf 200 to be adjusted in position horizontally relative to the frame.

[0047] For example, the first connector 11 is a bolt, the end of which forms the aforementioned plug 111 that inserts into the slot 211. The end of the bolt has a hexagonal groove, and the first connector 11 can be rotated by inserting a wrench into the hexagonal groove, which is convenient to operate. Optionally, the end of the base 12 is provided with a clearance opening 123, so that a wrench can pass through the clearance opening 123 to rotate the first connector 11.

[0048] The base 12 is also provided with a second locking hole 121, which is connected to the threaded hole on the base 12. After the position of the first connecting member 11 is adjusted, the second locking member 13 passes through the second locking hole 121 and its end abuts against the first connecting member 11, thereby locking the first connecting member 11 relative to the base 12. The second locking member 13 is like a set screw.

[0049] The connecting component 2 also includes a rotating shaft 22. The hinge 23 has a through hole 231. The rotating shaft 22 passes through the through hole 231 and is rotatably connected to the hinge 23. The rotating shaft 22 is vertically connected to the second connecting member 21 and can move vertically relative to the second connecting member 21, thereby enabling the door leaf 200 to move vertically relative to the frame and achieve vertical position adjustment. For example, the rotating shaft 22 has a second external thread, and the second connecting member 21 has a threaded hole. The rotating shaft 22 passes through the threaded hole, and the second external thread and the threaded hole are threadedly connected. On the one hand, this connects the rotating shaft 22 and the second connecting member 21. On the other hand, by rotating the rotating shaft 22, the position of the rotating shaft 22 relative to the second connecting member 21 can be adjusted vertically, thereby achieving vertical position adjustment of the door leaf 200.

[0050] Optionally, the second connector 21 includes a main body 212 and an extension 213 provided on the side of the main body 212. The main body 212 is threadedly connected to the rotating shaft 22, and the extension 213 is provided with a slot 211 for insertion into the first connector 11.

[0051] The connecting assembly 2 also includes a sliding sleeve 26 and two sleeves 25. The two sleeves 25 are installed at both ends of the through hole 231 of the hinge 23. The rotating shaft 22 passes through and rotates on the two sleeves 25, so that the rotating shaft 22 is rotatably connected to the hinge 23 through the sleeves 25. One end of the rotating shaft 22 is threaded to the second connecting member 21, and the other end is provided with an end cap 222. The sliding sleeve 26 and the hinge 23 are sequentially sleeved on the rotating shaft 22. One end of the hinge 23 abuts against the end cap 222 through the sleeve 25 and one end of the sliding sleeve 26, and the other end abuts against the second connecting member 21 through the other sleeve 25. The sliding sleeve 26 can realize the sliding connection between the hinge 23 and the end cap 222. Both the sleeves 25 and the sliding sleeve 26 can prevent the hinge 23 from directly contacting the rotating shaft 22 and the second connecting member 21, thus preventing wear on the hinge 23.

[0052] The pivot 22 has a groove 221, and the hinge 23 has a first locking hole 232 communicating with the through hole 231. The first locking member 24 passes through the first locking hole 232 and is confined in the groove 221, thereby limiting the relative displacement between the hinge 23 and the pivot 22 and achieving locking between them. For example, the groove 221 is an annular groove opened along the circumference of the pivot 22, and the first locking member 24 can abut against the bottom of the annular groove. The first locking member 24 is a set screw or a screw.

[0053] The frame is connected to an adjustable profile on its side. The hinge mounting structure also includes a locking assembly 3 on the second connector 21, which is used to connect with the adjustable profile. Optionally, the locking assembly 3 includes a shaped locking block 31 and a locking rod 32. The locking rod 32 is parallel to the first connector 11. The shaped locking block 31 is connected to the second adjusting seat through the locking rod 32. For example, the locking rod 32 is connected to the connecting hole 214 opened in the extension 213. The shaped locking block 31 is used to engage with the mounting groove 110 of the adjustable profile on the frame to drive the adjustable profile to adjust its position synchronously. For example, the shaped locking block 31 is elongated 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 110, it can enter through the groove opening of the mounting groove 110. After rotation, its protrusions lock when they touch the groove sidewall of the mounting groove 110.

[0054] By setting up locking component 3 and adjusting profile, the adjusting profile is connected to the door leaf 200 through locking component 3 and adjusting seat. When the door leaf 200 moves, the adjusting profile moves synchronously. The amount of pressure on the sealing strip between the adjusting profile and the door leaf 200 remains constant, ensuring good sealing performance. This avoids the problem of excessive gaps between the frame and the door leaf 200 due to accumulated errors from production errors, installation errors, and adjustments of the door leaf 200, which can lead to insufficient pressure on the sealing strip and reduced sealing performance. In other words, it solves the problem of water leakage caused by increased gaps between the door leaf 200 and the frame after adjustment. This is more suitable for folding doors requiring a larger adjustment range, as the addition of adjusting profile improves the gaps in the door leaf 200 and enhances airtightness.

[0055] The locking rod 32 is a screw, the irregular locking block 31 is threadedly connected to the locking rod 32, the connecting hole 214 is a threaded hole, the locking rod 32 passes through the threaded hole and is threadedly connected to the threaded hole.

[0056] Optionally, one or more sets of locking components 3 can be provided. Correspondingly, an equal number of connecting holes 214 are provided on the second adjusting seat. By increasing the number of locking components 3, the installation stability and reliability of the adjusting profile can be improved.

[0057] Example 3

[0058] like Figure 5 As shown, this embodiment provides a door and window system and hinge installation structure, which is basically the same as the structure of Embodiment 2, except that: the first connecting member 11 is rod-shaped, the first connecting member 11 is provided with a plug 111, and the plug 111 has limiting blocks 112 at both ends, which can restrict the second connecting member 21 from moving axially along the first connecting member 11. Compared with Figure 4 The structure shown in Embodiment 2 enables the thinning design of the second connector 21.
