Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, specifically relating to a one-way adjustable slot-free invisible hinge. Background Technology

[0002] Traditional surface-mounted hinges typically only provide basic turning functionality. Exposed hinges, screws, and pivots disrupt the visual continuity between the door leaf and frame, "dividing" a complete door into several parts. This is particularly jarring in minimalist, clean designs. Exposed hinges mean their pivots and fixing screws are exposed, making them vulnerable to vandalism or technical unlocking. Once installed, the position of ordinary surface-mounted hinges is fixed. If the door sags or deforms due to gravity, causing difficulty in opening and closing, it's difficult to fine-tune and often requires reinstallation or shims, which is very troublesome. These are the main technical problems with existing hinges that cannot be concealed. Utility Model Content

[0003] This addresses the technical issues of insufficient aesthetics and poor security of existing surface-mounted hinges.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a one-way adjustable slotless invisible hinge, comprising a housing and an inner sleeve. The housing includes an invisible groove and a connecting opening, the connecting opening being located on the side of the invisible groove. Mounting holes are provided in both side walls of the connecting opening. The inner sleeve includes a door leaf connecting portion and a housing hinge portion, the housing hinge portion being located on one side of the door leaf connecting portion. The interior of the housing hinge portion is hollow. The housing hinge portion of the inner sleeve is located within the connecting opening of the housing. The upper and lower ends of the hollow structure of the housing hinge portion are aligned vertically with the mounting holes on both sides, respectively. A hinge core is provided in the hollow structure of the inner sleeve and in the mounting holes on both sides. The housing and the inner sleeve move around the hinge core as an axis. The door leaf connecting portion is located within the invisible groove.

[0005] Furthermore, the inner sleeve has height adjustment grooves at both the upper and lower ends of the door leaf connection part, and fasteners that are fixedly connected to the door leaf are provided in the height adjustment grooves.

[0006] Furthermore, the surface of the inner door panel connection is provided with an inner decorative panel.

[0007] Furthermore, the inner decorative panel is bonded to the inner sleeve using 3M adhesive.

[0008] Furthermore, the hinge core is fitted with a spacer on the outer side of both the upper and lower ends, and the spacer is located between the hinge part of the inner box and the side wall of the box.

[0009] Furthermore, the box body has door frame connecting parts at both ends, and the door frame connecting parts have connecting holes, and the connecting holes have fasteners that are fixedly connected to the door frame.

[0010] Furthermore, the surface of the door frame connection is provided with a box-shaped decorative panel.

[0011] Furthermore, the decorative panel of the box can be bonded to the box body using 3M adhesive.

[0012] The present invention has the following advantages: the box body is fixedly installed with the door frame, and the inner sleeve is fixedly installed with the door leaf. When the door leaf and the door frame need to be closed, the box body and the inner sleeve move around the hinge core, so that the door leaf connecting part of the inner sleeve is placed in the hidden groove of the box body to complete the storage and realize the hidden hinge. The hinge is completely hidden in the door gap, and the hinge shape cannot be seen from any angle, making the lines between the door leaf and the door frame clean and neat. Since the hinge is hidden inside, when the door is closed, the rotating shaft and connecting parts of the hinge cannot be accessed from the outside, which greatly improves the door's anti-pry capability and security.

Detailed Implementation

[0020] This utility model provides a technical solution to the problem of installing ultra-narrow aluminum alloy door frames without slotting. Its key feature is the optimization of the door panel connection structure, creating a vertically adjustable, square, integrated structure that is concealed within the door frame housing through an embedded design. The door panel mounting surface and the door frame mounting surface are at the same height, thus eliminating the need for slotting on one side of the door panel during installation, while only requiring a small square slot on one side of the door frame, thereby solving the installation problem of ultra-narrow aluminum alloy doors.

[0021] Meanwhile, the door frame mounting box has been further optimized, reducing its height within the aluminum alloy frame to less than 8mm, making it compatible with most aluminum profiles on the market. To improve the load-bearing capacity of this concealed hinge, we have designed a wraparound structure for the door frame box, extending the connection length of the pivot.

[0022] like Figures 1 to 6 As shown, a one-way adjustable slotless invisible hinge includes a housing 10 and an inner sleeve 20. The housing 10 includes an invisible groove 11 and a connecting opening 12. The connecting opening 12 is located on the side of the invisible groove 11. Mounting holes 13 are provided in both side walls of the connecting opening 12. The inner sleeve 20 includes a door leaf connecting part 21 and a housing hinge part 22. The housing hinge part 22 is located on one side of the door leaf connecting part 21. The interior of the housing hinge part 22 is hollow. The housing hinge part 22 of the inner sleeve 20 is located in the connecting opening 12 of the housing 10. The upper and lower ends of the hollow structure of the housing hinge part 22 are aligned with the mounting holes 13 on both sides. A hinge core 14 is provided in the hollow structure of the inner sleeve 20 and in the mounting holes 13 on both sides, so that the housing 10 and the inner sleeve 20 are hinged through the hinge core 14.

[0023] When in use, the box 10 is fixedly installed with the door frame, and the inner sleeve 20 is fixedly installed with the door leaf. When the door leaf and the door frame need to be closed, the box 10 and the inner sleeve 20 move around the hinge core 14, so that the door leaf connecting part 21 of the inner sleeve 20 is placed in the hidden groove 11 of the box 10 to complete the storage and realize the hidden hinge. The hinge is completely hidden in the door gap, and the hinge shape cannot be seen from any angle, making the lines between the door leaf and the door frame clean and neat. Since the hinge is hidden inside, when the door is closed, the rotating shaft and connecting parts of the hinge cannot be accessed from the outside, which greatly improves the door's anti-pry capability and security.

[0024] The inner sleeve 20 has height adjustment grooves 23 at both the upper and lower ends of the door leaf connection part 21. The height adjustment grooves 23 are equipped with fasteners that are fixedly connected to the door leaf. When the position between the inner sleeve 20 and the door leaf needs to be set, first loosen the fasteners connected to the door leaf, then move the inner sleeve up and down, adjust to the appropriate position, and then tighten the fasteners to complete the position adjustment.

[0025] In order to conceal the internal structure of the door leaf connection part 21 of the inner sleeve 20 and make the product more aesthetically pleasing, the surface of the inner sleeve door leaf connection part 21 is provided with an inner sleeve decorative panel 24, which can be bonded to the inner sleeve 20 with 3M adhesive.

[0026] The hinge core 14 is fitted with a spacer 15 on the outer side of its upper and lower ends. The spacer 15 is located between the hinge part 22 of the inner sleeve 20 and the side wall of the box body 10. During use, the spacer can reduce the friction between the box body and the inner sleeve and extend the service life of the hinge.

[0027] The two ends of the box body 10 are respectively provided with door frame connecting parts 16. The door frame connecting parts 16 are provided with connecting holes 17. The connecting holes 17 are provided with fasteners that are fixedly connected to the door frame. The surface of the door frame connecting parts 16 is provided with a box body decorative panel 18. The box body decorative panel 18 and the box body 10 can be bonded together with 3M adhesive. The box body decorative panel can make the overall appearance of the hinge more beautiful.
