Description

Technical Field

[0001] This utility model relates to the field of building sound insulation technology, specifically a building sound insulation structure. Background Technology

[0002] Building sound insulation is a technology that uses material selection and structural design (such as soundproof walls, soundproof doors and windows) to block or absorb sound transmission. Its core value is not only to "reduce noise", but also to improve the practicality of buildings from multiple dimensions such as living experience, health and safety, quality of life and asset value.

[0003] In daily life, the sound insulation of room doors is particularly important, as it can block out the sound of televisions in the living room, family conversations, and the noise of kitchen range hoods, ensuring undisturbed rest. However, existing room doors often have a gap between the bottom of the door and the ground to prevent friction and allow the door to open and close freely. This gap, however, facilitates sound transmission and therefore needs improvement. To address this, a new building sound insulation structure is proposed. Utility Model Content

It includes a sound insulation plate 401, an inverted U-shaped plate 402 is fixedly installed on the upper end of the sound insulation plate 401, a plurality of guide holes 403 are provided on the inverted U-shaped plate 402, the plurality of guide holes 403 are arranged in a linear array, a connecting plate 404 is fixedly installed on the upper middle part of the inverted U-shaped plate 402, and a trigger plate 405 is fixedly installed on the upper middle part of the connecting plate 404.

[0027] The guide assembly 300, located above the sound insulation assembly 400, guides the sound insulation panel 401. It includes a fixing block 301, which is fixedly connected to the door body 100 via a fixing assembly 500. The guide assembly 300 has an internal movable groove 302 for accommodating the inverted U-shaped plate 402. Several guide posts 304 are arranged inside the movable groove 302, with their upper and lower ends fixedly connected to the upper and lower inner walls of the movable groove 302. Each guide post 304 is connected to a specific guide post. Holes 403 correspond one-to-one, guide posts 304 slide and fit with guide holes 403, springs 305 are wound around the outer surface of guide posts 304, the bottom of springs 305 are fixedly connected to the bottom of the inner cavity of movable groove 302, the upper end of springs 305 are fixedly connected to the bottom of inverted U-shaped plate 402, a central through groove 306 is opened in the middle of the upper end of movable groove 302, connecting plate 404 slides and fits with central through groove 306, a storage groove 307 is opened at the opening of central through groove 306, and the storage groove 307 is compatible with trigger plate 405;

[0028] Baffle 600 is located at the upper end of fixed block 301 and moves relative to fixed block 301 via sliding component 700.

[0029] The movable groove 302 has side holes 303 on both sides of its bottom. The side holes 303 extend to the bottom of the fixed block 301 and are used to accommodate the two parallel plates of the inverted U-shaped plate 402.

[0030] The fixing component 500 includes a fixing plate 501, which is distributed in a U-shape at the edge of the fixing block 301. The fixing plate 501 and the fixing block 301 are integrally formed, and the fixing plate 501 is fixedly connected to the door body 100 by multiple fixing screws 502.

[0031] like Figure 5 As shown, the sliding component 700 includes a slider 701, which is fixedly connected to the bottom side of the baffle 600. The length of the slider 701 is less than the length of the baffle 600. The upper end of the fixing block 301 is provided with a sliding groove 702, which is located on one side of the storage groove 307. The slider 701 slides and fits with the slider 701. The upper end of the sliding groove 702 is provided with a connecting groove 703, which is used to accommodate the connection area between the baffle 600 and the slider 701.

[0034] This utility model provides a building sound insulation structure, the specific working principle of which is as follows:

[0035] Initially, under the pressure of the movable groove 302 (which is always in a compressed state), the upper end of the inverted U-shaped plate 402 will adhere to the top of the inner cavity of the movable groove 302. At this time, the bottom of the sound insulation plate 401 is aligned with the bottom of the door 100, and the trigger plate 405 will protrude from the upper surface of the guide assembly 300. After the door 100 is closed, press the trigger plate 405 down by hand to further compress the movable groove 302. After the trigger plate 405 is embedded in the storage groove 307, move the baffle 600 so that... When the baffle 600 blocks the upper surface of the trigger plate 405, the sound insulation plate 401 moves downward and just blocks the gap at the bottom of the door 100, thereby reducing the sound propagation path and improving the sound insulation effect of the door 100. When the door needs to be opened, the baffle 600 is moved to one side of the trigger plate 405. Under the action of the spring 305 restoring its deformation, the inverted U-shaped plate 402 will move upward, thereby moving the sound insulation plate 401 upward to return to its initial position, so as to prevent the sound insulation plate 401 from affecting the movement of the door 100.

[0036] The hinge and mechanical locking structure of door 1 are common knowledge in this field, and a suitable model can be selected, so they will not be described in detail here.

[0037] It should be noted that the need for additional sound insulation of the door is only required when people are inside closing the door. When no one is inside, there is basically no need for additional sound insulation. Therefore, the sound insulation component can be installed only on the inside of the door 100.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
