Description

Technical Field

[0001] This utility model relates to the technical field of silent cabin hinge structure, specifically, to a silent cabin concealed top and bottom hinge. Background Technology

[0002] In modern society, soundproof booths, as facilities that provide quiet and independent spaces, are widely used in various scenarios such as offices, libraries, homes, and public places. They create an environment where people can focus on work, study, make phone calls, record, or rest, effectively isolating themselves from external noise interference and meeting people's needs for private and quiet spaces.

[0003] Traditional hinges often have rotating parts made of metal in direct contact. During the opening and closing of the door, the friction and collision between the metal parts can easily generate abnormal noises. These noises can disrupt the quiet environment inside the soundproof cabin, which contradicts the original design purpose of the soundproof cabin. Therefore, a hidden top and bottom hinge for soundproof cabins is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a silent cabin concealed hinge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a hidden hinge for a soundproof cabin, comprising a soundproof cabin body, a hidden door leaf on the soundproof cabin body, a hidden doorpost strip fixedly connected to the middle of the hidden door leaf, a mechanical lock located on one side of the hidden door leaf away from the center, limit strips on the top and bottom sides of the hidden door leaf, the two limit strips being fixedly connected to the inner walls of the top and bottom sides of the soundproof cabin body respectively, and a hinge assembly on the hidden doorpost strip. With the help of the two limit strips and the hinge assembly, the hidden door leaf rotates on the soundproof cabin body.

[0006] As a further improvement to this technical solution, the hinge assembly includes a first flush door leaf step and a second flush door leaf step. Both of the limiting strips are provided with circular mounting grooves. A first limiting post is fixedly connected to the bottom side of the first flush door leaf step. A first gasket is sleeved on the outer side of the first limiting post. A first bearing is fixedly sleeved on the bottom end of the first flush door leaf step, and the first bearing is located at the bottom of the first gasket. The first bearing is engaged in one of the circular mounting grooves.

[0007] As a further improvement to this technical solution, a second limiting post is fixedly connected to the top side of the second flush door leaf step, a second gasket is sleeved on the outer side of the second limiting post, a second bearing is fixedly sleeved on the top of the second gasket, the second bearing is located on the top of the second gasket, and the second bearing is engaged in another circular mounting groove.

[0008] As a further improvement to this technical solution, the first flush door leaf step and the second flush door leaf step are respectively snapped onto the concealed door post strip, and the first flush door leaf step and the second flush door leaf step are symmetrically arranged.

[0009] As a further improvement to this technical solution, two fresh air hoods are provided on the top side of the main body of the soundproof cabin, and the two fresh air hoods are arranged far apart from each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In the concealed hinges of the soundproof cabin, the hinge assembly allows the concealed door panel and concealed doorpost strip to rotate between two limit strips. At the same time, the sound emitted when the concealed door panel and concealed doorpost strip open and close is relatively small. This is mainly achieved by two first bearings and two second bearings. In addition, the first and second gaskets reduce the spread of noise and prevent abnormal noises from disrupting the quiet environment inside the soundproof cabin. Attached Figure Description

[0019] Please see Figures 1-3 As shown, this embodiment provides a silent cabin concealed hinge, including a silent cabin body 1, a concealed door 2 on the silent cabin body 1, a concealed doorpost strip 3 fixedly connected to the middle of the concealed door 2, a mechanical lock on one side of the concealed door 2 away from the center, limit strips 4 on the top and bottom sides of the concealed door 2, the two limit strips 4 being fixedly connected to the inner walls of the top and bottom sides of the silent cabin body 1 respectively, and a hinge assembly 5 on the concealed doorpost strip 3. With the help of the two limit strips 4 and the hinge assembly 5, the concealed door 2 rotates on the silent cabin body 1.

[0020] In practical applications, the soundproof cabin body 1, as a facility that can provide a quiet and independent space, is widely used in various scenarios such as offices, libraries, homes, and public places. Due to the design defects of the existing soundproof cabin body 1, it is easy to produce abnormal noise when closing the door, which violates the original design intention of the soundproof cabin body 1. By using the hinge assembly 5 set on the invisible door post strip 3, the abnormal noise can be reduced when opening and closing. At the same time, under the action of the first bearing 504 and the second bearing 509, the resistance of the invisible door post strip 3 and the invisible door leaf 2 is reduced when opening and closing.

[0021] Please see Figures 1-3As shown, the hinge assembly 5 includes a first flush door leaf step 501 and a second flush door leaf step 506. Both limiting strips 4 have circular mounting grooves 505. A first limiting post 502 is fixedly connected to the bottom side of the first flush door leaf step 501. A first gasket 503 is sleeved on the outer side of the first limiting post 502. A first bearing 504 is fixedly sleeved at the bottom end of the first flush door leaf step 501, and the first bearing 504 is located at the bottom of the first gasket 503. The first bearing 504 is engaged in one of the circular mounting grooves 505. The second flush door leaf step 506... A second limiting post 507 is fixedly connected to the top side of the door leaf step 506. A second gasket 508 is sleeved on the outside of the second limiting post 507. A second bearing 509 is fixedly sleeved on the top of the second gasket 508. The second bearing 509 is located on the top of the second gasket 508 and is engaged in another circular mounting groove 505. The first flush door leaf step 501 and the second flush door leaf step 506 are respectively engaged on the concealed door post strip 3, and the first flush door leaf step 501 and the second flush door leaf step 506 are symmetrically arranged.

[0022] In practical applications, the hinge assembly 5 allows the concealed door panel 2 and the concealed doorpost strip 3 to rotate between the two limiting strips 4. The opening and closing of the concealed door panel 2 and the concealed doorpost strip 3 is relatively quiet, primarily due to the opening and closing achieved by the two first bearings 504 and the second bearing 509. Furthermore, the first gasket 503 and the second gasket 508 reduce noise diffusion, preventing abnormal noises from disrupting the quiet environment inside the soundproof chamber.

[0023] Please see Figure 1 As shown, two fresh air hoods 6 are provided on the top side of the soundproof cabin body 1, and the two fresh air hoods 6 are arranged far apart from each other.

[0024] In practical applications, the two fresh air hoods 6 can ventilate the main body 1 of the soundproof cabin, thereby achieving the effect of air exchange inside the main body 1 of the soundproof cabin and allowing air to circulate inside the main body 1 of the soundproof cabin.
