Description

TECHNICAL FIELD

[0001] The utility model relates to sound insulation accessories technical field especially, it relates to a sound insulation device convenient to dismount. BACKGROUND

[0002] At present, the door structure is usually provided with elastic rubber strip at the bottom, which is used for tightly abutting with the door frame or the door sill and the like structure to achieve the sound insulation, dust prevention and sealing effects inside and outside the door. However, the elastic rubber strip is usually made of rubber or plastic material, and with long time use, the rubber or plastic material will age, harden, deform and the like, which reduces the sealing effect and leads to the significant decrease of sound insulation performance. When the elastic rubber strip needs to be replaced due to aging or damage, it needs to be disassembled by bending down, and the process is usually more complicated. On the other hand, in the closing process of the existing door body structure, even if the damping assembly is installed to slow down the impact force when closing the door, the collision phenomenon between the door and the door frame is still inevitable. Such collision not only produces a large noise, which affects the user experience, but also causes damage to the sound insulation device due to long-term impact, which shortens the service life of the door body. SUMMARY

[0003] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to provide a sound insulation device convenient to dismount, which adopts the following technical scheme:

[0004] A sound insulation device convenient to dismount is arranged between an openable and closable movable plate and a blocking plate, which comprises

[0005] A mounting piece is detachably fixed in a clamping groove of the movable plate, a cavity is arranged in the middle of the mounting piece, and a mounting slot is arranged on the side of the cavity close to the blocking plate;

[0011] Further, the cavity is provided with a limiting groove, the wide end of the mounting part is clamped in the limiting groove, and the shape of the limiting groove matches the shape of the wide end of the mounting part.

[0012] Further, the elastic rubber strip can move forward and backward along the opening direction of the mounting slot, when the movable plate is closed with the blocking plate, the elastic rubber strip moves into the cavity, and the trailing edge of the abutting part abuts against the leading edge of the mounting slot; when the movable plate is separated from the blocking plate, the mounting part is reset under the action of the limiting groove.

[0013] Further, the distance of forward or backward movement of the elastic rubber strip is 3-8mm.

[0014] Further, the clamping groove is a T-shaped groove penetrating along the width direction of the movable plate.

[0029] Example 1

[0030] like Figure 1 and Figure 2As shown, this application provides a sound insulation device that is easy to assemble and disassemble, disposed between an openable movable plate 300 and a barrier plate 400, including a mounting component 1 and an elastic rubber strip 2. Specifically, a T-shaped groove extending through the movable plate 300 along its depth direction serves as a slot 301 for connecting the mounting component 1. One end of the mounting component 1 is provided with a snap-fit ​​portion matching the T-shaped groove, and the length of the mounting component 1 is consistent with the depth length of the movable plate 300. The other end of the mounting component 1 is provided with an elastic rubber strip 2. More specifically, in one embodiment, the movable plate 300 is a door, and the barrier plate 400 is a threshold stone. The aforementioned mounting component 1 and elastic rubber strip 2 are disposed at the lower edge of the door. When the door is closed, the elastic rubber strip 2 abuts against the threshold stone, achieving the effect of sound insulation on both the inside and outside of the door.

[0031] Furthermore, such as Figure 1 As shown, the mounting component 1 has a cavity 11 in the middle. The cavity 11 has a mounting slot 12 on the side near the baffle plate 400. One end of the elastic rubber strip 2 is detachably installed inside the cavity 11 through the mounting slot 12, and the other end extends to the outside of the cavity 11 to abut against the baffle plate 400.

[0032] Preferably, mounting component 1 is made of aluminum alloy, which has high strength, good rigidity, is not easily deformed, and is easy to process. The elastic rubber strip 2 is made of rubber, which has excellent elasticity and resilience. During installation, first press one end of the elastic rubber strip 2 into the cavity 11 along the mounting groove 12 to fix it, and then insert the mounting component 1 into the T-slot from the side of the movable plate 300. During disassembly, the elastic rubber strip 2 can be removed together with the mounting component 1, and then the elastic rubber strip 2 can be separated from the mounting component 1. Clean the residual elastic rubber strip 2 debris in the mounting groove 12 due to aging or damage. There is no need to bend over to operate, which saves time and effort and is convenient to operate.

[0033] like Figure 1 and Figure 2 As shown, the elastic rubber strip 2 includes an abutment part 21, an installation part 23, and a connecting part 22 that connects the abutment part 21 and the installation part 23. The connecting part 22 passes through the installation slot 12, and the installation part 23 is disposed inside the cavity 11 and engages with the inner side of the installation slot 12. The abutment part 21 is used to abut against the baffle plate 400.

[0034] In one specific embodiment, the longitudinal section of the mounting part 23 is a trapezoid with a wider front and a narrower back. The wider end of the mounting part 23 is larger than the width of the mounting groove 12, and the narrower end is smaller than the width of the mounting groove 12. When installing the elastic rubber strip 2, the narrower end of the mounting part 23 is aligned with the mounting groove 12, and the abutment part 21 is pressed towards the inside of the cavity 11. The mounting part 23 is gradually pressed into the cavity 11 from one side to the other. The installation process is simple.

[0035] like Figure 1 and Figure 2As shown, for ease of installation, an arc-shaped guide edge is provided on the front side of the mounting slot 12 to facilitate the entry of the mounting part 23.

[0036] like Figure 1 and Figure 2 As shown, the abutment part 21 is hollow inside, and the side near the baffle plate 400 is arc-shaped. When the movable plate 300 abuts against the baffle plate 400, the hollow abutment part 21 deforms and fits tightly against the baffle plate 400, which enhances the sound insulation effect. At the same time, it can also save the processing cost of the elastic rubber strip 2 and improve the shock absorption effect of the abutment part 21.

[0037] Example 2

[0038] like Figure 3 As shown, the difference from Embodiment 1 is that a limiting groove 13 is provided in the cavity 11, the wide end of the mounting part 23 is engaged in the inside of the limiting groove 13, and the shape of the limiting groove 13 matches the shape of the wide end of the mounting part 23.

[0039] The technical effect achieved by the above structure is that the elastic rubber strip 2 can move back and forth along the opening direction of the mounting groove 12. Specifically, the longitudinal cross-sectional shape of the limiting groove 13 is a right-angled triangle with the base facing forward. After the elastic rubber strip 2 is inserted into the mounting part 1, the wide end of the mounting part 23, which has a trapezoidal cross-section, extends into the limiting groove 13. The limiting groove 13 matches the shape of the wide end of the mounting part 23. For the specific structure, please refer to [reference needed]. Figure 3 When the movable plate 300 and the baffle plate 400 are closed, the elastic rubber strip 2 moves into the cavity 11, and the rear edge of the abutting part 21 abuts against the front edge of the mounting slot 12.

[0040] In this process, such as Figure 3 As shown, under the action of the limiting groove 13, the mounting part 23 deforms, and the elastic rubber strip 2 moves into the cavity 11. The air in the cavity 11 is compressed and discharged from the gap between the elastic rubber strip 2 and the mounting part 1. This process creates resistance to the elastic rubber strip 2, forming a buffering effect, improving the service life of the rubber strip, and reducing the impact between the blocking plate 400 and the movable plate 300 when the plate is closed forcefully. When the movable plate 300 separates from the blocking plate 400, the mounting part 23 resets under the action of the limiting groove 13 due to the elastic rebound energy of the elastic rubber strip 2 itself. Preferably, the distance that the elastic rubber strip 2 moves forward or backward is 3 to 8 mm.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
