DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Please refer to Figures 1 - 7 , which are the structural diagrams of the adjustable hinge mechanism of the present utility model and the structures of its components respectively.

[0024] As shown in the figure, the embodiment of the present utility model provides an adjustable hinge mechanism, the overall structure of which includes a hinge fan 1, a hinge frame 4 and a shaft 5. The hinge fan 1 is connected to the hinge frame 4 through the shaft 5. An up-and-down adjustment assembly is provided between the hinge frame 4 and the hinge fan 1, and a left-and-right adjustment assembly is provided on the hinge fan 1. The up-and-down adjustment assembly is fixed to the hinge frame 4 through a set screw 8, and the hinge frame 4 is fixed to the door frame profile through a positioning pin 3.

[0025] Among them, the up-and-down adjustment assembly includes an up-and-down adjustment screw 9 and a bushing 7. The bushing 7 is sleeved in the shaft hole of the hinge frame 4. The up-and-down adjustment screw 9 is screwed into the shaft hole of the hinge frame 4. The bottom end of the bushing 7 abuts against the up-and-down adjustment screw 9. The bushing 7 is fixed to the hinge frame 4 through a set screw 8. Thus, by adjusting the up-and-down movement of the up-and-down adjustment screw 9, the bushing 7 is driven to move up and down.

[0026] During specific adjustment, use an Allen wrench to loosen the set screw, and adjust the up-and-down adjustment screw up or down, which can drive the bushing to move in the up-and-down direction, and then drive the hinge fan to move up and down, so that the up-and-down overlap amount of the door leaf can be adjusted without disassembling the door leaf. Specifically, a distance adjustment of ±2 mm in the up-and-down direction can be achieved.

[0027] Among them, the top end of the bushing 7 is an external hexagonal nut 11, and the front and rear sealing of the door leaf can be adjusted by rotating the bushing 7. The bushing 7 is an eccentric structure, and the different apex angles or sides of the external hexagon are used to abut against the hinge frame, so as to adjust the sealing performance. Specifically, a sealing adjustment effect of ±2 mm can be achieved, as Figure 5 shown.

[0028] During specific adjustment, first use an Allen wrench to loosen the set screw, and then use a wrench to rotate the bushing so that the positioning groove in the bushing coincides with the protrusion of the hinge frame to achieve initial positioning. Then tighten the set screw, so that the sealing performance of the door leaf can be adjusted without disassembling the door leaf.

[0029] In a possible implementation, please refer to Figure 7 As shown, a plurality of positioning grooves 15 are arranged along the circumferential direction on the outer wall of the bottom end of the bushing 7, and a plurality of protrusions (not shown in the figure) for positioning in cooperation with the positioning grooves are arranged on the inner wall of the hinge frame 4. Through the design of the positioning grooves, initial positioning can be achieved when rotating to different positions during the rotation of the bushing, and further locked by the set screw.

[0030] Among them, the left and right adjustment components include a left and right adjustment slider 2 and a left and right adjustment screw 10. The left and right adjustment slider 2 cooperates with the two chute through holes of the hinge fan 1, and the left and right adjustment slider 2 is provided with a threaded hole that cooperates with the left and right adjustment screw 10 for screwing, so that the hinge fan 1 and the left and right adjustment slider 2 can be driven to move left and right under the action of the left and right adjustment screw 10.

[0031] During specific adjustment, use an Allen wrench to adjust the left and right adjustment screws. Under the action of the left and right adjustment screws, the hinge fan and the left and right adjustment slider can move relative to each other in a direction perpendicular to the hinge frame, so that the left and right overlap of the door leaf can be adjusted without disassembling the door leaf. Specifically, an adjustment effect of ±2 mm for the left and right overlap can be achieved.

[0032] Among them, in a possible implementation, a card slot is provided on the hinge fan, and a part of the left and right adjustment screw is placed in the card slot.

[0033] Among them, in a possible implementation, please refer to Figure 6 As shown, there is a gap 12 between the hinge fan 1 and the shaft 5, and the angle between the hinge fan 1 and the hinge frame 4 is adjusted by the hinge adjustment screw 6. Specifically, in the normal state, the hinge fan and the hinge frame are at 90 degrees. The hinge adjustment screw can be adjusted with an Allen wrench, and the hinge fan can be lifted up, so that the problem of the door leaf falling off the corner can be solved. Specifically, a maximum angle adjustment of 2° can be achieved. As Figure 6 shown, the left side is the normal state and the right side is the adjusted state.

[0034] Among them, in a possible implementation, in order to achieve the aesthetic effect of the overall hinge, a hinge decorative cover 14 is also provided on the hinge fan. The main function of the hinge decorative cover is to cover the internal components to achieve the overall simple and beautiful effect of the product. The hinge decorative cover can be fixed to the hinge fan by conventional connection methods. For the purpose of convenient disassembly and assembly, for example, connection methods such as snap connection, snap fit, and socket connection can be used, and the specific implementation form of the present utility model is not specifically limited.

[0035] Through the above detailed description of the adjustable hinge mechanism in combination with the attached drawings of the present invention, it can be understood that the adjustable hinge mechanism of the present invention includes a hinge frame, a hinge leaf, and a shaft. The hinge leaf is connected to the hinge frame through the shaft. An up-and-down adjustment assembly is provided between the hinge frame and the hinge leaf, and a left-and-right adjustment assembly is provided on the hinge leaf. The up-and-down adjustment assembly is fixed to the hinge frame through set screws, and the hinge frame is fixed to the door frame profile through positioning pins. The up-and-down adjustment of the hinge can be achieved through the up-and-down adjustment assembly, and the left-and-right adjustment can be achieved through the left-and-right adjustment assembly. Moreover, the sleeve structure of the up-and-down adjustment assembly can be further utilized to complete the adjustment of the sealing performance. Therefore, the adjustable hinge mechanism of the present invention can achieve high load-bearing capacity and realize three-dimensional adjustment without disassembling the door leaf.

[0036] Furthermore, through the gap between the hinge leaf insertion shaft positions, the hinge leaf can be lifted upward by using the hinge adjustment screw, so as to adjust the problem of the door leaf corner dropping and solve the problem of the door leaf corner dropping.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
