[0033] Reference Figures 1 to 5 A hinge with smooth-fitting rotating arms includes: a base 100, an adjusting seat 200, and a rotating arm assembly 300. The adjusting seat 200 is disposed on the base 100 and can be adjusted in position relative to the base 100. The rotating arm assembly 300 includes at least two rotating arms 310, which are movably connected to the adjusting seat 200. The adjusting seat 200 includes a seat body 210 and a mating component 220. The seat body 210 and the mating component 220 are separate structures. The seat body 210 is disposed on the base 100, and the mating component 220 is connected to the seat body 210. The mating component 220 is provided with at least two rotating arm connecting portions for correspondingly connecting the rotating arms 310. The seat body 210 and the rotating arms 310 are metal parts, and the mating component 220 is a self-lubricating plastic part.
[0034] With the above structure, the adjusting seat 200 is divided into two parts: a metal seat body 210 and a self-lubricating plastic mating part 220. The rotating arm 310 does not directly mate with the metal seat body 210, but rather with the mating part 220. The smoothness of the mating of the rotating arm 310 is improved by the self-lubricating effect of the plastic part. In addition, for different rotating arms 310, the mating part 220 is provided with a one-to-one rotating arm connecting part for mating, so that all rotating arms 310 are uniformly connected to the mating part 220, thereby avoiding the need for multiple bushings. The structure is simple and the assembly is convenient.
[0035] In this embodiment, the seat body 210 and the rotating arm 310 are metal parts, which may be zinc, copper, aluminum or their alloys; the mating part 220 is a self-lubricating plastic part, which may be nylon, POM or other self-lubricating plastics.
[0036] In this embodiment, mating parts 220 are arranged in pairs on the seat body 210. The two mating parts 220 clamp the rotating arm 310. The rotating arm 310 and the two mating parts 220 respectively cooperate, so that the structure is balanced and the connection is stable.
[0037] In this embodiment, the base 100 and the adjusting seat 200 are provided in two sets to form two single-sided components. Each adjusting seat 200 of the two single-sided components includes a seat body 210 and a mating component 220. The two ends of the rotating arm 310 are respectively connected to the mating components 220 of the two single-sided components. It is conceivable that, for cost or structural considerations, only a portion of the adjusting seat 200 may be configured with a combination of the seat body 210 and the mating component 220.
[0038] In this embodiment, two single-sided components are used to fix the door and the door frame respectively. Specifically, the two bases 100 can be fixed to the door and the door frame respectively with screws. In this embodiment, the body 210 of the adjusting seat 200 of one of the single-sided components is provided with a front-to-back adjusting slot 211. A front-to-back adjusting screw 400 passes through the front-to-back adjusting slot 211 and is threaded to the corresponding base 100. Thus, the adjusting seat 200 can be adjusted in front and back relative to the base 100 to realize the front-to-back adjustment of the door. The main body 210 of the adjustment seat 200 of another single-sided component is divided into two parts: the front side 212 and the bottom side 213. The corresponding base 100 is threaded with left and right adjustment screws 500. The bottom side 213 is provided with a through hole 2131. The left and right adjustment screws 500 pass through the through hole 2131 and are threaded to the corresponding base 100. The front side 212 and the bottom side 213 hold the nuts of the left and right adjustment screws 500. The front side 212 is provided with an upper and lower adjustment bar hole 2121. The upper and lower adjustment bar hole 2121 extends vertically. The upper and lower adjustment screws 600 pass through the upper and lower adjustment bar hole 2121 and are threaded to the bottom side 213. When the left-right adjusting screw 500 is turned, the left-right position of the entire adjusting seat 200 can be adjusted, thereby realizing the left-right adjustment of the door; when the up-down adjusting screw 600 is loosened, the up-down position of the face side part 212 relative to the bottom side part 213 can be adjusted. The face side part 212 is used to connect with the hinge arm 310. Through the above structure, the hinge can be adjusted in three dimensions, and the door can be adjusted relative to the door frame in the up-down, front-back, and left-right directions.
[0039] In this embodiment, at least one swing arm connecting portion is a groove 221 and at least one swing arm connecting portion is a shaft hole 222. One swing arm 310 is provided with a sliding pivot 311, and the other swing arm 310 is provided with a rotating pivot 312. The sliding pivot 311 is slidably disposed in the groove 221 and can rotate within the groove 221. The rotating pivot 312 engages with the shaft hole 222. With the above structure, the mating part 220 integrates both the groove 221 and the shaft hole 222, and can be used by the swing arm assembly 300 that requires both the groove 221 and the shaft hole 222 for engagement. In some embodiments, if the swing arm assembly 300 adopts, for example, a four-swing arm 310 structure, all swing arm connecting portions can be provided as shaft holes 222, and the number of such holes can be adaptively set according to the number of positions that the swing arms 310 need to connect. It is understood that the number, structure, and arrangement of the swing arm connecting portions provided on the mating part 220 can be adaptively set according to the structure adopted by the swing arm assembly 300.
[0040] In this embodiment, the sliding pivot 311 and the rotating pivot 312 extend symmetrically from both sides of the rotating arm 310. The grooves 221 of the paired mating parts 220 engage with the sliding pivot 311 on the corresponding side, and the shaft holes 222 of the paired mating parts 220 engage with the rotating pivot 312 on the corresponding side. With the above structure, the structure is balanced, and the movement of the rotating arm 310 is smooth.
[0041] In this embodiment, the mating component 220 is provided with a plug-in post 223, and the base body 210 is provided with a plug-in hole 214. The plug-in hole 214 is adapted to and plugs into the plug-in post 223. The shaft hole 222 is a hollow hole in the plug-in post 223. The rotating arm 310 is provided with a rotating pivot 312, which is disposed in the shaft hole 222. With the above structure, the rotating pivot 312 can stably support both the base body 210 and the mating component 220 simultaneously, providing stable support. In addition, a stable connection can also be formed between the mating component 220 and the base body 210 through the above structure.
[0042] In this embodiment, the slide groove 221 is open at least one end along its extending direction. A rotating arm 310 is provided with a sliding pivot 311, which is slidably disposed in the slide groove 221 and rotatable relative to it. The sliding pivot 311 can enter and exit the slide groove 221 through the opening at its end. The opening in the slide groove 221 facilitates the assembly and disassembly of the sliding pivot 311 of the rotating arm 310.
[0043] In this embodiment, the end faces of the seat body 210 and the mating component 220 that mate with each other are concave and convex end faces, and the seat body 210 and the mating component 220 are interlocked through the concave and convex end faces. Using the above structure, the mating between the seat body 210 and the mating component 220 can be accurately achieved, and the overall structure is more stable.
[0044] In this embodiment, the mating component 220 includes a main body plate 224 and an overlapping plate 225. The main body plate 224 and the overlapping plate 225 are connected to each other and arranged perpendicularly to each other. The overlapping plate 225 overlaps one end face of the seat body 210, and the main body plate 224 fits snugly against the seat body 210. With the above structure, the fit between the mating component 220 and the seat body 210 is more stable.
[0045] 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.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
