Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a hidden hinge. Background Art

[0002] Hinges play an important role in people's lives. Hinges occupy an important position in furniture hardware accessories. The quality of hinges is directly related to the use of furniture and doors. With the continuous improvement of people's living standards, adjustable hidden hinges are also constantly improved to meet people's needs. However, there are still some deficiencies in the adjustable hidden hinges in the existing technology. For example, when the door panel is opened, some adjustment parts such as adjusting screws and locking screws will be exposed, which affects the overall sense and appearance of the furniture after the door is opened. In addition, due to long-term exposure to air, the screws are eroded by moisture and dust in the air, causing them to rust, making the screws unusable, affecting the performance and service life of the hidden hinges. Utility Model Content

[0040] Reference below Figure 1-Figure 5 A hidden hinge is described in detail with a specific embodiment. It is worth noting that the following description is merely an illustrative description and is not intended to limit the utility model.

[0041] like Figure 1-Figure 5 As shown, a hidden hinge includes a fan housing 100, a frame housing 130 and a dustproof decorative cover 210.

[0042] Among them, a fan bracket 110 is provided in the fan housing 100, and a drive shaft 120 is installed in the fan bracket 110; a frame bracket 140 is provided in the frame housing 130, and an adjusting swing arm 150 is installed in the frame bracket 140. The adjusting swing arm 150 is provided with a swing arm assembly and is hinged to the drive shaft 120, and an adjusting cavity 160 is provided on the adjusting swing arm 150, and an adjusting screw 170 and a locking screw 180 are installed in the adjusting cavity 160. The bottom of the adjusting cavity 160 is provided with a docking hole 190, and the top edge of the adjusting cavity 160 is provided with a side hole 200; a dustproof decorative cover 210 is installed at the opening of the adjusting cavity 160, and the bottom surface of the dustproof decorative cover 210 is provided with a docking column 220 docking with the docking hole 190, and the upper part of the docking column 220 is provided with a rebound notch 230. The fan housing 100 is installed on the door leaf, and a fan bracket 110 is set inside the fan housing 100 to install the drive shaft 120. The frame housing 130 is installed in the door frame, and a frame bracket 140 is set inside the frame housing 130 to install the adjustment swing arm 150. The adjustment swing arm 150 is provided with a swing arm assembly and is hinged with the drive shaft 120, so that the door leaf and the door frame can be opened and closed. An adjusting chamber 160 is provided on the adjusting swing arm 150, and an adjusting screw 170 and a locking screw 180 are installed in the adjusting chamber 160, which can adjust the position of the door leaf and lock it. By setting a dustproof decorative cover 210, the adjusting screw 170 and the locking screw 180 can be hidden from view, thereby achieving an aesthetic and dustproof effect. The bottom surface of the dustproof decorative cover 210 is provided with a docking column 220 docked with the docking hole 190, and the upper part of the docking column 220 is provided with a rebound notch 230. During installation, tightening the rebound notch 230 is conducive to the coordinated installation of the docking column 220 and the docking hole 190. After installation, the rebound notch 230 rebounds to connect and tighten the dustproof decorative cover 210 to the adjusting chamber 160. The top edge of the adjusting chamber 160 is provided with a side hole 200 to facilitate the opening of the dustproof decorative cover 210. Therefore, the hidden hinge can prevent the adjusting screw 170 and the locking screw 180 from being exposed, thereby achieving an aesthetic and dustproof effect and preventing the screws from corroding and rusting. In addition, the dustproof decorative cover 210 is easy to disassemble and assemble, and is convenient to use.

[0043] Specifically, if Figure 3 and Figure 4As shown, the projections of the adjustment cavity 160 and the dustproof decorative cover 210 are both rectangular. This makes it easier to arrange the adjustment cavity 160 and install the dustproof decorative cover 210. Furthermore, the dustproof decorative cover 210 is provided with a side edge 240 that mates with the upper edge of the adjustment cavity 160. This facilitates docking and installation with the upper edge of the adjustment cavity 160. Furthermore, the side edge 240 of the dustproof decorative cover 210 is provided with a supporting post 250 that abuts the bottom surface of the adjustment cavity 160. The supporting post 250 provides support for the dustproof decorative cover 210, thereby ensuring the installation depth of the dustproof decorative cover 210. The resilient notch 230 on the docking post 220 also reduces pressure on the docking post 220. Furthermore, both the docking hole 190 and the docking post 220 are cylindrical in shape. This cylindrical shape facilitates docking between the docking hole 190 and the docking post 220. Furthermore, the top of the docking post 220 is beveled. The bevel can play a guiding role, which is conducive to the insertion of the docking column 220 into the docking hole 190. It is understandable that there are two docking holes 190 and docking columns 220. The two docking holes 190 and docking columns 220 play a positioning role and also play a reinforcing role.

[0044] like Figure 1 、 Figure 2 and Figure 5 As shown, both ends of the fan housing 100 and the frame housing 130 are provided with lugs 260, which are provided with mounting holes 270. Lugs 260 are provided with snap-fits 280 on both sides of the lugs 260. An ear cover 290 is provided on the mounting surface of the lug 260, and snap-fits 300 are provided on both sides of the ear cover 290 to engage with the snap-fits 280. The snap-fits 280 on both sides of the lug 260 and the snap-fits 300 on both sides of the ear cover 290 facilitate the snap-fit ​​installation of the ear cover 290 on the lug 260, thereby preventing the mounting screws in the mounting holes 270 from being exposed. This provides an aesthetically pleasing and dustproof effect, preventing the screws from corroding and rusting. Furthermore, the dustproof decorative cover 210 is easy to assemble and disassemble, making it convenient to use.

[0045] like Figure 1 and Figure 2 As shown, the swing arm assembly includes a concave plate 310 and a convex rocker arm 320. The concave plate 310 is hingedly connected to the adjustment swing arm 150, while the convex rocker arm 320 is hingedly connected to the drive shaft 120. The concave plate 310 has a notch that mates with the convex rocker arm 320 and is hingedly connected via a rotating shaft. The swing arm assembly facilitates the hinged connection between the adjustment swing arm 150 and the drive shaft 120 through the concave plate 310 and the convex rocker arm 320, ensuring smooth opening and closing of the door leaf.

[0046] It is worth mentioning that the two sides of the notch are connected with reinforcing ribs 330. The reinforcing ribs 330 are provided to connect the notches of the concave plate 310. On the one hand, the notch can be covered to improve the appearance, and on the other hand, the load-bearing capacity of the hinge can be enhanced.

In this specification, illustrative uses of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention 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 invention.
