They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0026] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0027] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0028] 1 and 2 , a three-dimensional adjustable dimming hinge according to an embodiment of the present application includes a hinge body 100 , a first hinge seat 200 , a second hinge seat 300 and an adjustment assembly 400 .

[0029] Among them, the hinge body 100 is formed by a hinge combination with two middle sections hinged to each other, one hinge is provided with a first adjustment block 110 at both ends, and the other hinge is provided with a second adjustment block 120 at both ends. The two ends of the hinge with the second adjustment block 120 are respectively slidably connected to the two first adjustment blocks 110, and the two ends of the hinge with the first adjustment block 110 are respectively slidably connected to the two second adjustment blocks 120 to ensure that the hinge body 100 can be smoothly unfolded or folded.

[0030] The first adjustment block 110 is connected to the first hinge base 200, and the second adjustment block 120 is connected to the second hinge base 300. Both the first hinge base 200 and the second hinge base 300 are provided with a receiving slot 201 for accommodating the folded hinge. The first hinge base 200 is typically connected to the door frame, while the second hinge base 300 is connected to the door body, thus achieving the installation of a three-dimensional adjustable concealing hinge.

[0031] It should be noted that the three-dimensional adjustment of the hinge is solely dependent on the first and second adjustment blocks 110, 120 at the ends of the hinge body 100, and is unrelated to the structure of the two hinge leaves. Therefore, the hinge body 100 can be a simple, easy-to-install five-axis hinge, or a strong, flexible seven-axis hinge. Users can also choose other hinge body 100 types based on their specific needs, as long as the hinge body 100 can be smoothly unfolded or folded to fit within the accommodating slot 201.

[0032] 2 and 3 , it can be understood that rotatable rivet screws 210 are respectively provided at both ends of the inside of the first hinge seat 200, that is, the rivet screws 210 are riveted to the first hinge seat 200 and rotatably cooperate with the first hinge seat 200. The front end of the rivet screw 210 is provided with a hexagonal slot for the user to rotate. The rivet screw 210 is extended in the front and rear directions. The rivet screw 210 corresponds one-to-one with the first adjustment block 110 and is threadedly cooperated. The rivet screw 210 is rotated to drive the second hinge seat 300 to move relative to the first hinge seat 200 in the front and rear directions through the hinge body 100; the first adjustment block 110 is provided with a locking screw 111, which is threadedly installed on the first adjustment block 110 and abuts against the first hinge seat 200.

[0033] By setting the locking screw 111, after the user rotates the rivet screw 210 to adjust the position of the second hinge seat 300, the user can continue to rotate the locking screw 111 to make the locking screw 111 abut against the first hinge seat 200, thereby cooperating with the rivet screw 210 to lock the first adjustment block 110, preventing the first adjustment block 110 from loosening, effectively improving the installation stability of the first adjustment block 110, and thereby improving the overall structural stability of the hinge.

[0034] 2 and 4 , it can be understood that connecting platforms 310 are respectively provided at both ends of the interior of the second hinge seat 300; the adjustment component 400 is arranged in a one-to-one correspondence with the connecting platform 310, and the adjustment component 400 is located between the second adjustment block 120 and the connecting platform 310. The second adjustment block 120 is connected to the connecting platform 310 through the adjustment component 400, and the adjustment component 400 is used to drive the first hinge seat 200 to move relative to the second hinge seat 300.

[0035] Specifically, the adjustment assembly 400 includes a third adjustment block 420, a first adjustment member 430 and a second adjustment member 440, the limit screw 410 is installed on the third adjustment block 420, the third adjustment block 420 is slidably connected to the connecting platform 310 in the vertical direction, the first adjustment member 430 is connected to the connecting platform 310 and is suitable for locking or releasing the third adjustment block 420, the second adjustment block 120 is slidably connected to the third adjustment block 420 in the left and right directions, and the second adjustment member 440 is connected to the third adjustment block 420 and is suitable for locking or releasing the second adjustment block 120.

[0036] The first adjusting member 430 is usually configured as a bolt structure that is easy to operate and adjust, and the third adjusting block 420 is locked or released by rotating the first adjusting member 430. The first adjusting member 430 and the second adjusting member 440 are usually similar in structure to improve the structural consistency of the entire hinge.

[0037] The user can move the second adjustment block 120 to drive the first hinge seat 200 to move in the left and right direction relative to the second hinge seat 300, and then fix the movable second adjustment block 120 to the third adjustment block 420 through the second adjustment member 440 to complete the left and right position adjustment of the hinge; the user can also move the third adjustment block 420 to drive the first hinge seat 200 to move in the vertical direction relative to the second hinge seat 300, and then fix the movable third adjustment block 420 to the connecting platform 310 through the first adjustment member 430 to complete the vertical position adjustment of the hinge.

[0038] By providing the third adjustment block 420, the first adjustment member 430, and the second adjustment member 440, the left-right and vertical adjustment functions of the adjustment assembly 400 can be distinguished and independently locked or released. The rivet screw 210, the first adjustment member 430, and the second adjustment member 440 are combined to achieve three-dimensional position adjustment of the hinge, facilitating user assembly and adjustment of the door. Furthermore, the third adjustment block 420, the first adjustment member 430, and the second adjustment member 440 simplify the structure of the adjustment assembly 400 and facilitate user assembly and use.

[0039] 4 and 5 , it can be understood that the first adjusting member 430 is a first screw 431 , the third adjusting block 420 is provided with a first waist-shaped hole 4202 arranged in a vertical direction, the first screw 431 is passed through the first waist-shaped hole 4202 and is connected to the connecting platform 310 .

[0040] A first screw 431 is inserted through the first waist-shaped hole 4202, allowing the third adjustment block 420 to slide vertically with the connecting platform 310. A user can tighten or loosen the third adjustment block 420 by turning the first screw 431. Using the first adjustment member 430 as the first screw 431 further simplifies the structure of the adjustment assembly 400, significantly reducing the production and design costs of the hinge.

[0041] It should be noted that when the first adjusting member 430 is configured as a first screw 431, the first adjusting member 430 compresses the third adjusting block 420 via the screw head. Alternatively, the first adjusting member 430 can be configured as a nut. In this case, the connecting platform 310 is provided with a stud that passes through the first waist-shaped hole 4202, and the nut engages with the stud in a threaded manner. By configuring the stud and nut, the user can tighten or loosen the third adjusting block 420 by turning the nut. Since the structure and effect of the first adjusting member 430 configured as a nut are similar to those of the first screw 431, they will not be further described here.

[0042] 4 and 5 , it can be understood that a gasket 432 is provided between the screw head of the first screw 431 and the third adjusting block 420 , the gasket 432 is sleeved on the first screw 431 , and the outer diameter of the gasket 432 is greater than the diameter of the first waist-shaped hole 4202 .

[0043] By setting the gasket 432, on the one hand, the gasket 432 can disperse the pressure of the screw head or nut, and by increasing the contact area and improving the contact conditions, the reliability of the first adjusting member 430 is improved, ensuring that the first adjusting member 430 is more stable when subjected to force; on the other hand, since the first screw 431 needs to adjust the installation position of the third adjusting block 420 within the range of the first waist-shaped hole 4202, at this time, setting a gasket 432 with an outer diameter larger than the diameter of the first waist-shaped hole 4202 can provide convenience for installation and adjustment of the first adjusting member 430, compensate for the position deviation of the first waist-shaped hole 4202, ensure that the first adjusting member 430 can be installed correctly, and reduce the accuracy and assembly requirements of the first adjusting member 430.

[0044] 4 and 6 (part of the second hinge seat 300 structure has been omitted), it should be added that the second adjusting member 440 can be set as a second screw with a structure similar to the first screw 431, and a gasket 432 is provided between the second screw and the second adjusting block 120. The connection structure and effect of the second screw can refer to the previous description of the first screw 431 and will not be repeated here.

[0045] 2 and 4 , it can be understood that the second hinge seat 300 is connected to a cover plate 330, which can be screwed, clamped, or glued to the second hinge seat 300, which will not be described in detail here. The cover plate 330 matches the appearance of the second hinge seat 300, and the cover plate 330 is located on the side of the third adjustment block 420 away from the connecting platform 310 to cover the adjustment assembly 400. At the same time, the first hinge seat 200 is also connected to a panel structure for covering the rivet screws 210 and the locking screws 111.

[0046] By providing the cover plate 330 , the adjustment component 400 can be hidden inside the second hinge seat 300 , thereby improving the overall aesthetics of the hinge while reducing the impact of the external environment on the adjustment component 400 , further extending the service life of the adjustment component 400 .

[0047] 4 and 6 , it can be understood that the second hinge seat 300 is provided with two limiting portions 320, which are symmetrically arranged on both sides of the connecting platform 310 and are integrally formed with the second hinge seat 300. The two limiting portions 320 are respectively provided with limiting inclined surfaces 321 on one side facing the third adjustment block 420, and the adjustment component 400 includes a limiting screw 410, which abuts against the corresponding limiting inclined surfaces 321 to limit the adjustment component 400 in the vertical direction.

[0048] It should be noted that the rivet screws 210 of the first hinge seat 200 and the connecting platform 310 of the second hinge seat 300 are symmetrically arranged to ensure that the hinge can be applied to door bodies with different door opening directions (that is, the hinge can be used upright or inverted). Since the connecting platforms 310 are respectively provided at both ends of the second hinge seat 300, two limiting parts 320 are provided on both sides of each connecting platform 310, and each limiting part 320 is provided with a limiting inclined surface 321.

[0049] The limiting bevel 321 generally has two forms. One of the limiting bevels 321 is offset forward along the front-to-back direction at one end of the limiting bevel 321 near the center of the second hinge seat 300. In this case, the limiting bevel 321 located below the hinge body 100 abuts against the corresponding limiting screw 410 to disperse the stress of the door body. The other limiting bevel 321 is offset forward along the front-to-back direction at one end of the limiting bevel 321 away from the center of the second hinge seat 300. In this case, the limiting bevel 321 located above the hinge body 100 abuts against the corresponding limiting screw 410 to disperse the stress of the door body. The form of the limiting bevel 321 is not specifically limited herein, as long as it can cooperate with the limiting screw 410 to disperse the stress of the door body and extend the service life of the hinge.

[0050] It should be added that the first hinge seat 200 and the second hinge seat 300 can be integrally formed by die-casting, pouring, milling and other processes. The processing is fast and stable, with high consistency, which can ensure that the first hinge seat 200 and the second hinge seat 300 have good structural strength.

[0051] 4 and 5 , it can be understood that two protrusions 421 are provided on the side of the third adjustment block 420 facing the limiting inclined surface 321, and the protrusions 421 extend toward the limiting portion 320 in the front-to-back direction. The limiting screw 410 is passed through the protrusion 421, and a first guide groove 4201 is formed between the two protrusions 421 and the inner end surface of the third adjustment block 420. The connecting platform 310 is slidably assembled in the first guide groove 4201 along the vertical direction.

[0052] By providing the protrusions 421, the guide groove formed between the two protrusions 421 can guide the third adjustment block 420 to move on the connecting platform 310 in the vertical direction, effectively improving the fit between the third adjustment block 420 and the connecting platform 310 and improving the movement stability of the third limit block.

[0053] It should be added that a limiting groove 4203 is provided on the front end face of the third adjustment block 420. The limiting groove 4203 cooperates with the second screw to limit the deflection of the second adjustment block 120 and guide the second adjustment member 440 to move along the left and right directions on the third adjustment block 420, thereby effectively improving the fit between the second adjustment block 120 and the third adjustment block 420 and improving the movement stability of the second limiting block.

[0054] 4 , it can be understood that the limiting portion 320 of the second hinge seat 300 is provided with a pressing surface 322 , which is connected to an end of the limiting inclined surface 321 close to the third adjustment block 420 and abuts against the protrusion 421 .

[0055] Because the third adjustment block 420 has a protrusion 421, when the first screw 431 is tightening the third adjustment block 420, the protrusion 421 may contact the limiting portion 320. The provision of the pressing surface 322 increases the contact area between the protrusion 421 and the limiting portion 320, preventing the edge of the limiting inclined surface 321 from scraping the protrusion 421 and affecting the movement of the third adjustment block 420.

[0056] 4 and 6 , it can be understood that the third adjustment block 420 is provided with a connecting portion 422, the second adjustment member 440 is connected to the connecting portion 422, a second guide groove 3201 is formed between the two limiting portions 320 and the inner end surface of the second hinge seat 300, and the rear end of the connecting portion 422 is slidably assembled in the second guide groove 3201 along the vertical direction.

[0057] By setting the second guide groove 3201, on the one hand, the internal space of the second hinge seat 300 is reasonably utilized to set the second guide groove 3201, and the second guide groove 3201 guides the movement of the connecting part 422, further improving the movement stability of the third limit block while improving the space utilization of the hinge; on the other hand, since the second screw is installed on the connecting part 422, after the user adjusts the hinge in three dimensions, the second screw can be rotated so that the second screw passes through the connecting part 422 and abuts against the inner end surface of the second hinge seat 300. At this time, the second screw can approximate the effect of the locking screw 111, that is, the second screw can cooperate with the first screw 431 to lock the third adjustment block 420, effectively improving the installation stability of the third adjustment block 420, and further improving the overall structural stability of the hinge.

[0058] It can be understood that by setting the rivet screws 210 and the adjustment assembly 400, the user can adjust the position of the door body in three dimensions through the rivet screws 210, the first adjustment member 430 and the second adjustment member 440 when installing the door body, so that the door body and the door frame are aligned, ensuring installation accuracy and reducing adjustment difficulty.

[0059] By setting the limiting screw 410 and the limiting bevel 321, on the one hand, the limiting bevel 321 is located in the second hinge seat 300 and is integrally formed with the second hinge seat 300, which can simplify the hinge structure, reduce the assembly requirements of the hinge, facilitate user assembly and use, and improve the appearance of the hinge; on the other hand, the limiting bevel 321 and the second hinge seat 300 are integrally formed, and when the limiting screw 410 and the limiting bevel 321 are locked, the hinge can disperse the stress of part of the door body through the limiting bevel 321, relieve the pressure of the adjustment component 400, and effectively extend the service life of the hinge.

[0060] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
