Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware accessories, specifically to a concealed adjustable hinge suitable for curtain wall profiles. Background Technology

[0002] Currently, hinges, as a common rotating connector between two profiles, are frequently used for connecting doors and windows. Hinges on the market generally consist of frame hinges, sash hinges, and a pivot. The frame and sash hinges rotate relative to each other around the pivot, thus opening and closing the window sash. However, traditional hinges are not adjustable after installation, making vertical movement difficult, and their exposed structure results in relatively poor aesthetics. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a concealed adjustable hinge applicable to curtain wall profiles, which can solve the problems of difficulty in adjusting the position after the hinge is installed and the inability to conceal the installation. The installation structure is simple and the overall aesthetics of the curtain wall after installation are high.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0005] A concealed adjustable hinge suitable for curtain wall profiles includes a pivot, a frame hinge, a sash hinge, a clamping block that mates with the frame hinge and the sash hinge, and fastening screws. The frame hinge and the sash hinge are rotatably connected via the pivot. Both the frame hinge and the sash hinge are clamped to the clamping block by the fastening screws, which include countersunk screws and self-tapping screws. The clamping force between the frame hinge and the sash hinge and the clamping block is adjusted by the countersunk screws. The frame hinge and the sash hinge with the clamping block are fixedly connected to the profile by the self-tapping screws. The outer end of the frame hinge and / or the sash hinge is also provided with an adjustment mechanism, which allows the installation position of the frame hinge and the sash hinge on the profile to be adjusted vertically.

[0006] Preferably, the adjustment mechanism includes an adjustment block, an adjustment screw hole on the adjustment block, an adjustment screw rod in the adjustment screw hole, and a plurality of self-tapping screws for fixing the adjustment block, wherein the front end of the adjustment screw rod abuts against one side of the frame hinge or the fan hinge.

[0007] Preferably, the frame hinge has a C-shaped structure, the fan hinge has a Z-shaped structure, the frame hinge and the fan hinge are connected by the pivot to form a double-wing structure, and the clamping surfaces of the frame hinge and the fan hinge are offset to the same side of the pivot.

[0008] Preferably, one side of the frame hinge is recessed towards the axis of the rotating shaft to form a first clamping groove, the outer side of the frame hinge is provided with a C-shaped positioning groove, and the side of the fan hinge away from the rotating shaft is recessed towards the axis of the rotating shaft to form a second clamping groove. The installed clamping blocks are respectively located in the first clamping groove and the second clamping groove.

[0009] Preferably, both the first clamping groove and the second clamping groove have an outwardly protruding clamping strip at one end near the rotating shaft. One side of the clamping block has a top edge that bends toward the frame hinge and the fan hinge. One side of the clamping block abuts against one side of the frame hinge and the fan hinge through the top edge. The clamping block and the clamping strip clamp and fix one side of the mounting surface of the profile.

[0010] Preferably, the top edge is made up of multiple edges and is spaced apart.

[0011] Preferably, both the frame hinge and the fan hinge are provided with a through hole, a bushing is provided in the through hole, and a stop ring is provided at one end of the bushing. The rotating shaft is connected to the through hole through the bushing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The frame hinges and sash hinges are first connected to the clamps using countersunk screws. The tightness of the clamps allows for vertical movement of the entire hinge. Once the hinge is in place, it is tightened and secured again with self-tapping screws. This effectively avoids the problem of difficulty in vertical adjustment that exists with existing hinges that are directly positioned to the profile using self-tapping screws during installation, especially the difficulty in readjusting vertically after installation. Additionally, one side of the hinge is equipped with an adjustment mechanism that drives the hinge to move, thus preventing the hinge from sliding awkwardly after being connected with countersunk screws.

[0020] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] like Figures 1-3 As shown, a concealed adjustable hinge suitable for curtain wall profiles includes a pivot 5, a frame hinge 1, a sash hinge 10, a clamping block 6 that cooperates with the frame hinge 1 and the sash hinge 10, and fastening screws 9. The frame hinge 1 and the sash hinge 10 are rotatably connected by the pivot 5. The frame hinge 1 and the sash hinge 10 are connected and clamped to the clamping block 6 by the fastening screws 9. The fastening screws 9 include countersunk screws 91 and self-tapping screws 92. The clamping force between the frame hinge 1 and the sash hinge 10 and the clamping block 6 is adjusted by the countersunk screws 91. The frame hinge 1 and the sash hinge 10, with the clamping block 6 installed, are fixedly connected to the profile by the self-tapping screws 92. The outer end of the frame hinge 1 and / or the sash hinge 10 is also provided with an adjustment mechanism 8, and the installation position of the frame hinge 1 and the sash hinge 10 on the profile can be adjusted up and down by the adjustment mechanism 8.

[0022] During hinge installation, frame hinge 1 and sash hinge 10 are connected to clamping block 6 via countersunk screws 91 to clamp and position the clamping area of ​​the profile mounting groove. After frame hinge 1 and sash hinge 10 are positioned, self-tapping screws 92 are used to securely fix the frame hinge 1 and sash hinge 10 with clamping block 6 to the profile, thus completing the fixation. Specifically, frame hinge 1 and sash hinge 10 are first connected to clamping block 6 via countersunk screws 91. The tightness of clamping block 6 allows for vertical movement of the entire hinge. Once the hinge is in place, it is tightened and locked again with self-tapping screws 92. This effectively avoids the problem of difficulty in vertical adjustment that exists in existing hinges where self-tapping screws 92 are directly used for positioning with the profile during installation, especially the difficulty in vertical adjustment after installation. Additionally, one side of the hinge is equipped with an adjustment mechanism 8, which drives the hinge to move, thus preventing the hinge from sliding inconveniently after being connected with countersunk screws 91.

[0023] A further improvement is made to the adjustment mechanism 8, which includes an adjustment block 81, an adjustment screw hole 82 on the adjustment block 81, an adjustment screw 83 in the adjustment screw hole 82, and a plurality of self-tapping screws 92 for fixing the adjustment block 81, wherein the front end of the adjustment screw 83 abuts against one side of the frame hinge 1 or the fan hinge 10.

[0024] In actual operation, the adjusting block 81 is installed on the curtain wall profile with self-tapping screws 92, so that one end of the adjusting screw 83 abuts against the outside of the frame hinge 1 or the sash hinge 10. When it is necessary to move the overall position of the hinge up and down on the curtain wall profile, the adjusting screw 83 is rotated with a tool, and the adjusting screw 83 pushes against one side of the hinge. With the tightness control of the countersunk screw 91, the position of the hinge after installation can be effectively adjusted, so that it is installed in a suitable position, avoiding the problems of difficulty in height adjustment and inconvenience after the hinge is installed. The whole adjustment operation is simple and convenient.

[0025] A further improvement is made in that the frame hinge 1 has a C-shaped structure and the fan hinge 10 has a Z-shaped structure. The frame hinge 1 and the fan hinge 10 are connected by the pivot 5 to form a double-wing structure, and the clamping surfaces of the frame hinge 1 and the fan hinge 10 are offset to the same side of the pivot 5.

[0026] The hinges and sash hinges 10 are connected by the pivot 5 to form a double-wing structure. The clamping surfaces of the frame hinges 1 and the sash hinges 10 are offset to the same side of the pivot 5. When combined with the curtain wall profile, it can be installed in a concealed manner, which is more concealed and more aesthetically pleasing.

[0027] A further improvement is made in that one side of the frame hinge 1 is recessed towards the axis of the rotating shaft 5 to form a first clamping groove 12, the outer side of the frame hinge 1 is provided with a C-shaped positioning groove 2, and the side of the fan hinge 10 away from the rotating shaft 5 is recessed towards the axis of the rotating shaft 5 to form a second clamping groove 7. The installed clamping block 6 is located in the first clamping groove 12 and the second clamping groove 7 respectively.

[0028] The first clamping groove 12, the C-shaped positioning groove 2, and the second clamping groove 7 allow one end of the frame hinge 1 and the sash hinge 10 to extend into the mounting groove of the profile. This allows the frame hinge 1 and the sash hinge 10 to form a stable, mutually abutting clamping surface after being clamped with the clamping block 6, thus ensuring that the hinges are firmly installed on the profile and avoiding problems with poor stability after installation.

[0029] A further improvement is made in that a clamping strip 13 protruding outward is provided at one end of the first clamping groove 12 and the second clamping groove 7 near the rotating shaft 5. One side of the clamping block 6 is provided with a top edge 11 that bends toward the frame hinge 1 and the fan hinge 10. One side of the clamping block 6 abuts against one side of the frame hinge 1 and the fan hinge 10 through the top edge 11. The clamping block 6 and the clamping strip 13 clamp and fix one side of the mounting surface of the profile.

[0030] The outward-protruding clamping strip 13 cooperates with the clamping block 6 to achieve internal and external clamping, which ensures good stability during installation and reduces overall weight. The top edge 11 provides sufficient positioning surface for the hinge after installation, allowing it to be firmly installed on the profile and avoiding problems with poor stability after installation.

[0031] A further improvement is made in that the top edge 11 is multiple and spaced apart.

[0032] The top edge 11 is formed into an inclined and curved structure after stamping. The contact between the top edge 11 and the frame hinge 1 and the fan hinge 10 can play a supporting role on one side, preventing loosening after clamping. At the same time, the side of the clamping block 6 between the two top edges 11 can also play a role in strengthening and assisting in positioning.

[0033] A further improvement is that both the frame hinge 1 and the fan hinge 10 are provided with a through hole 14, a bushing 3 is provided in the through hole 14, a stop ring 4 is provided at one end of the bushing 3, and the rotating shaft 5 is connected to the through hole 14 through the bushing 3.

[0034] One end of the bushing 3 is inserted into the through hole 14. The bushing 3 has a countersunk hole, a stop ring 4 protruding outward at one end, and a sealing structure at the other end. The bushing 3 can connect and limit the installed rotating shaft 5, preventing the rotating shaft 5 from falling out after installation, and also improving the service life of the through hole 14. When the rotating shaft 5 or bushing 3 is worn, only the corresponding rotating shaft 5 or bushing 3 needs to be replaced to achieve maintenance, thus avoiding the problem of disassembling the entire hinge.

[0035] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
