Abstract
Description
Technical Field
[0001] This utility model relates to the field of noise-reducing wooden door technology, specifically to a spliced sound-insulating and noise-reducing wooden door. Background Technology
[0002] Interlocking soundproof and noise-reducing wooden doors are functional wooden doors made of modular design, multi-layer composite structure, and special sound insulation materials. They aim to reduce noise transmission (such as airborne sound and impact sound) and improve the indoor acoustic environment. In existing technologies, the outermost layer of the wooden door is made of solid wood boards, which can achieve an aesthetic effect. Further, sound-absorbing materials such as glass wool, polyester fiber, and foam ceramics are used as interlayers to achieve sound absorption and sound insulation effects. For example, the patent with announcement number CN216517684U discloses an interlocking soundproof wooden door. Specifically, it achieves the splicing of the door body by setting installation boxes on each door panel for the splicing panels to be embedded. However, although it can achieve the effect of splicing the door panels, gaps are inevitably left at the splicing points, which leads to sound leakage in the spliced door body, thereby reducing the noise reduction effect.
[0003] Based on the above description, there is an urgent need for a spliced soundproof and noise-reducing wooden door with a stable connection and good sound insulation effect. Utility Model Content
[0004] The purpose of this utility model is to provide a spliced soundproof and noise-reducing wooden door, which aims to solve the technical problem that existing doors inevitably have gaps at the splicing points, resulting in sound leakage after splicing and thus reducing the noise reduction effect.

Detailed Implementation
[0021] The specific implementation method is described below with reference to the accompanying drawings.
[0022] Example 1
[0023] Please see Figures 1 to 3 This utility model provides the following technical solution: a spliced soundproof and noise-reducing wooden door, applicable to the case of spliced soundproof and noise-reducing doors.
[0024] Specifically, such as Figures 1 to 3 As shown, a spliced soundproof and noise-reducing wooden door includes a head module 1, multiple unit modules 2, a tail module 3, and multiple snap-fit components 4; the snap-fit components 4 include a pair of vertical plates 41 and a horizontal partition 42; the pair of vertical plates 41 are divided into a pair of open slots 5 by the horizontal partition 42; the multiple unit modules 2 are located between the head module 1 and the tail module 3; the two ends of the unit modules 2, the bottom end of the head module 1, and the top end of the tail module 3 are all snapped into the slots of the open slots 5.
[0025] In this embodiment, a pair of vertical plates 41 are divided into a pair of open slots 5 by a horizontal partition 42. Then, when splicing the modules, by inserting the two ends of the unit module 2, the bottom end of the first module 1 and the top end of the tail module 3 into the slot of the open slot 5, the splicing point can be wrapped to avoid sound leakage at the splicing point and improve the noise reduction effect. At the same time, it can also achieve a stable splicing, ensure the stability of the entire door after splicing, and facilitate flexible disassembly and assembly.
[0026] In this embodiment, the head module 1, the multi-unit module 2, and the tail module 3 are all made of wood. Different types of wood or composite wood can be used depending on aesthetic or production requirements.
[0027] Specifically, such as Figures 1 to 3 As shown, the bottom of the first module 1 extends with a pair of side plates 6; each of the side plates 6 is embedded in both ends of an open slot 5 and engages with the open slot 5. A first inverted L-shaped locking block 10 is provided at one end of the side plate 6 near the open slot 5; both ends of the transverse partition 42 are recessed with slots for the ends of the first inverted L-shaped locking blocks 10 to be inserted. Supporting blocks 7 protrude from both sides of the transverse partition 42 to support the side plates 6; the slots are located at the ends of the transverse partition 42 near the supporting blocks 7.
[0028] In this embodiment, the pair of side plates 6 can serve as edging, and can also be further provided with a first inverted L-shaped locking block 10 to connect the bottom of the head module 1 to the horizontal partition 42, and then connect the horizontal partition 42 to the top of the unit module 2. The receiving block 7 is located in the middle of the outer wall of the horizontal partition 42, and is sandwiched between the side plate 6 and the vertical plate of the second inverted L-shaped locking block 11 at the top of the unit module 2; and so on, the side plate 6, the vertical plate of the second inverted L-shaped locking block 11, and the vertical plate of the third inverted L-shaped locking block 12 are spliced together to form the side of the door.
[0029] Specifically, such as Figure 2 and Figure 3 As shown, both sides of the transverse partition 42 are provided with grooves for multiple telescopic beads 8 to be inserted; the telescopic beads 8 are located in the side plate 6 near the end of the transverse partition 42.
[0030] In this embodiment, by embedding the telescopic ball 8 into the groove, the side plate 6 can be positioned on the outer side wall of the transverse partition 42 more quickly, thereby improving the stability of the door after splicing and the accuracy of splicing.
[0031] Specifically, such as Figure 2 and Figure 3 As shown, multiple limiting slide bars 9 are provided on one outer wall of unit module 2, one outer wall of head module 1, and one outer wall of tail module 3; the inner walls of a pair of vertical plates 41 are provided with limiting grooves for the limiting slide bars 9 to slide into.
[0032] In this embodiment, multiple limiting slides 9 slide into multiple limiting grooves to further ensure the stability of the assembled door and the accuracy of the assembly.
[0033] Specifically, such as Figure 1 and Figure 2 As shown, a pair of second inverted L-shaped locking blocks 11 are provided at both the bottom and top of unit module 2. A pair of third inverted L-shaped locking blocks 12 are provided at the top of the tail module 3.
[0034] In this embodiment, the snap-fit between the tail module 3 and the unit module 2, as well as the snap-fit between adjacent unit modules 2, are the same as the snap-fit between the head module 1 and the unit module 2. In this embodiment, the tail module 3 may not use the inverted L-shaped snap-fit block set on the inner side of the side plate 6, and can also be implemented by directly using the third inverted L-shaped snap-fit block 12.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, the unit module 2, the head module 1 and the tail module 3 are all provided with sound-insulating inner grooves 13.
[0036] In this embodiment, unit module 2, head module 1 and tail module 3 are equivalent to wooden shells, which can be further filled with various noise reduction, sound insulation or attraction materials to further improve the sound insulation effect of the spliced door.
