[0035] Reference Figures 1 to 8 A hinge capable of being configured with different decorative covers includes: two single-sided components 100 and a rotating arm structure 200. Each single-sided component 100 includes a mounting base 110 with a mounting portion 111 and a mounting hole 112. The rotating arm structure 200 connects the two single-sided components 100, forming a movable structure that allows relative rotation for opening and closing. The mounting portion 111 is also provided with a plastic cover mounting structure 113 and a metal cover mounting structure 114. The plastic cover mounting structure 113 is suitable for mounting a plastic decorative cover 300, and the metal cover mounting structure 114 is suitable for mounting a metal decorative cover 400. The plastic decorative cover 300 and the metal decorative cover 400 cover the mounting portion 111.

[0036] The hinge described above, by simultaneously providing a plastic cover mounting structure 113 and a metal cover mounting structure 114 to the mounting part 111 of the mounting base 110, allows the hinge to be fitted with either a plastic decorative cover 300 or a metal decorative cover 400 as needed, thereby avoiding the need to produce different hinges to accommodate the two decorative covers, and making manufacturing convenient.

[0037] In this embodiment, the plastic cover mounting structure 113 is a snap-fit ​​hole, and the plastic decorative cover 300 is provided with a snap-fit ​​post 310, which has a snap-fit ​​protrusion 311. The snap-fit ​​post 310 is used to insert into the snap-fit ​​hole, and the snap-fit ​​protrusion 311 is used to engage with the mounting part 111 to prevent the snap-fit ​​post 310 from disengaging from the snap-fit ​​hole. The plastic decorative cover 300 is installed using the above-described structure, which is simple and easy to install.

[0038] In this embodiment, the snap-fit ​​post 310 is formed by at least two snap-fit ​​pieces 312. One end of each snap-fit ​​piece 312 is connected to the cover surface of the plastic decorative cover 300. The snap-fit ​​pieces 312 are spaced apart and are elastic, allowing them to retract and expand. A snap-fit ​​protrusion 311 is located on the opposite side of the snap-fit ​​pieces 312. During the insertion of the snap-fit ​​post 310 into the snap-fit ​​hole, the snap-fit ​​pieces 312 can retract elastically, facilitating the insertion of the snap-fit ​​protrusion 311 into the snap-fit ​​hole. When the snap-fit ​​protrusion 311 reaches the position of the snap-fit ​​mounting part 111, the snap-fit ​​pieces 312 can expand elastically, allowing the snap-fit ​​protrusion 311 to automatically snap into place. This structure facilitates the installation of the snap-fit ​​post 310. In this embodiment, the snap-fit ​​protrusion 311 can snap onto the inner edge of the snap-fit ​​hole, or it can engage with the snap-fit ​​protrusion 311 by providing a snap-fit ​​step on the inner wall of the snap-fit ​​hole.

[0039] In this embodiment, for each individual plastic decorative cover 300, at least two sets of snap holes and snap posts 310 are provided, thereby enabling the plastic decorative cover 300 to be secured more firmly.

[0040] In this embodiment, the snap-on post 310 is integrally formed with the cover body of the plastic decorative cover 300, thereby facilitating manufacturing.

[0041] In this embodiment, the metal cover mounting structure 114 consists of snap-fit ​​portions located on the two opposite edges of the mounting portion 111. The two opposite sides of the metal decorative cover 400 are each provided with an elastic buckle 410. The metal decorative cover 400 is snapped into place by the elastic buckles 410 on both sides, corresponding to the two snap-fit ​​portions. Using the aforementioned metal cover mounting structure 114, the structure is simple, and the installation of the metal decorative cover 400 is convenient and secure.

[0042] In this embodiment, the elastic buckle 410 is a spring sheet, which is bent to form a crest portion 411, and the engaging portion is an engaging step. The elastic buckle 410 engages with the engaging step through the crest portion 411. With the above structure, the elastic buckle 410 has a simple structure and is easy to implement.

[0043] In this embodiment, the elastic buckle 410 and the cover body of the metal decorative cover 400 are integrally formed, which facilitates manufacturing.

[0044] In this embodiment, the mounting base 110 includes a base body 115 and two mounting parts 111. The two mounting parts 111 are respectively connected to the upper and lower ends of the base body 115, so that the mounting base 110 can be fixed at both the upper and lower ends, making the fixation more secure.

[0045] In this embodiment, one of the single-sided components 100 is provided with a left-right adjustment seat 120. The left-right adjustment seat 120 is slidably mounted on the mounting base 110 via a left-right guide limiting structure. The mounting base 110 is rotatably provided with a left-right adjustment stud 130. The left-right adjustment seat 120 is provided with a left-right adjustment screw hole 121, and the left-right adjustment stud 130 is threadedly connected to the left-right adjustment screw hole 121. The rotating arm structure 200 is connected to the left-right adjustment seat 120. By rotating the left-right adjustment stud 130, the left-right adjustment seat 120 can be adjusted left-right relative to the mounting base 110 through the threaded drive structure. Since the rotating arm structure 200 is connected to the left-right adjustment seat 120, the other single-sided component 100 can be adjusted left-right relative to it, thereby realizing the left-right position adjustment of the door relative to the door frame (door gap size adjustment). The left-right guide limiting structure ensures that the left-right adjustment seat 120 will not wobble and can stably adjust its left-right position.

[0046] In this embodiment, the upper and lower ends of the left and right adjustment seat 120 are provided with protrusions 122, and the mounting base 110 is provided with grooves 116 corresponding to the protrusions 122. The protrusions 122 are disposed in the corresponding grooves 116. The left and right guide and limiting structure includes two abutting protrusions 117 disposed on the opposite groove walls of the grooves 116. The two abutting protrusions 117 abut against the two sides of the protrusions 122 respectively and slide in cooperation with the protrusions 122. With the above structure, the left and right adjustment seat 120 can be stably guided and limited.

[0047] In this embodiment, the mounting base 110 is provided with a receiving cavity 118, and the left and right adjustment seat 120 is disposed in the receiving cavity 118. The left and right guide and limiting structure includes a guide insert 510 and a pair of limiting clips 520. The guide insert 510 and the pair of limiting clips 520 are respectively disposed on the cavity walls of the left and right adjustment seat 120 and the receiving cavity 118. The pair of limiting clips 520 are spaced apart and form a guide limiting groove 530. The guide insert 510 is adapted to the guide limiting groove 530 and is inserted into the guide limiting groove 530 and slides in cooperation with the pair of limiting clips 520. Two sets of guide inserts 510 and limiting clips 520 are provided and are respectively disposed on the upper and lower parts of the left and right adjustment seat 120. With the above structure, the guide and limiting of the left and right adjustment seat 120 can be achieved by the cooperation of the guide insert 510 and the guide limiting groove 530, resulting in more stable guidance and better limiting.

[0048] In this embodiment, both left and right guide and limiting structures function simultaneously, thereby enabling the left and right adjusting seats 120 to adjust their positions more stably and preventing them from becoming loose. It is conceivable that in some embodiments, only one type of left and right guide and limiting structure may be implemented.

[0049] In this embodiment, another single-sided component 100 is provided with a composite adjustment seat 140. The upper and lower ends of the composite adjustment seat 140 are respectively provided with front-to-back adjustment slots 141. The mounting base 110 is provided with upper-lower adjustment slots 119 corresponding to the two front-to-back adjustment slots 141. Composite adjustment screws 150 pass through the front-to-back adjustment slots 141 and the corresponding upper-lower adjustment slots 119. The composite adjustment screws 150 are threadedly connected to fastening nuts 160. The composite adjustment screws 150 and fastening nuts 160 are used to fasten the composite adjustment seat 140 to the mounting base 110. The rotating arm structure 200 is connected to the composite adjustment seat 140. With the above structure, when the composite adjustment screws 150 and fastening nuts 160 are loosened, the upper-lower and front-to-back positions of the composite adjustment seat 140 can be adjusted through the front-to-back adjustment slots 141 and the upper-lower adjustment slots 119. This allows for the adjustment of the vertical and horizontal positions of this single-sided component 100 relative to the other single-sided component 100, i.e., the adjustment of the front-to-back and vertical positions of the door relative to the door frame.

[0050] In this embodiment, the hinge structure 200 adopts a four-hinged structure. In other embodiments, the hinge structure 200 may also adopt a double-hinged structure or other structural forms. It is understood that there are many implementations of the hinge structure 200 that realizes the hinge function in the art. Those skilled in the art can configure it according to the actual situation, and it will not be repeated here.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
