Description

Technical Field

[0001] This application relates to a sound insulation firewall. Background Art

[0002] A sound insulation firewall is a special wall structure designed to isolate sound transmission, reduce sound propagation and reflection. By using sound-absorbing materials and sound-insulating materials, the sound insulation wall can effectively reduce sound propagation and reflection.

[0003] In the existing patent document "CN215054528U A heat-insulating and sound-insulating firewall structure", a sound insulation firewall is disclosed. Although this sound insulation firewall can be spliced, combined and fixed, gaps are likely to be left at the splicing joint positions, which may lead to sound leakage, thus reducing the sound insulation effect. At the same time, when used in an environment with relatively drastic temperature changes, due to temperature changes, the joints will expand and contract, and the contraction will cause the joints to widen, further leading to the problem of reduced sound insulation effect.

[0004] That is, the existing technology has the following technical problems. When an ordinary sound insulation firewall is used in an environment with relatively drastic temperature changes, due to temperature changes, the joints will expand and contract, resulting in a reduction in the sound insulation effect.

Further, this application designs a rubber gasket 4, through which the interface can be sealed to avoid the phenomenon of sound leakage at the joint, ensuring that the soundproof performance of the firewall reaches the best state. Further, in order to solve the problem in the prior art that when the ordinary spliced soundproof wall panel expands and contracts due to temperature changes, the joint is prone to expand, resulting in a reduction in the soundproof effect, this application designs a closed compensation member 6, through which the gap generated by shrinkage can be compensated, further playing the role of closing the joint, and is particularly suitable for use in an environment with a relatively high temperature change.

[0049] The splicing protrusion 2 is fixedly arranged on one side of the wall panel body 1, and fillets 201 are arranged at both the upper and lower ends of the splicing protrusion 2;

[0050] Circular grooves 202 are arranged on both the upper and lower sides of the arc surface of the splicing protrusion 2.

The locking component 5 includes a circular chute 501, a circular limiting slider 502, a push rod 503, a limiting spring 504 and a round head 505. The circular chute 501 is arranged inside the wall panel body 1, and a circular limiting slider 502 is slidably connected in the inner cavity of the circular chute 501;

[0053] One end of a limiting spring 504 is fixedly connected to one side wall of the circular limiting slider 502, and the other end of the limiting spring 504 is fixedly connected to the side wall of the circular chute 501;

[0054] One end of a push rod 503 is fixedly connected to the other side wall of the circular limiting slider 502. The other end of the push rod 503 extends to the splicing slot 3, and a round head 505 is fixedly arranged at one end of the push rod 503. Through this technical solution, when the wall panel body 1 needs to be spliced and combined and fixed, by docking and inserting the splicing protrusion 2 into the splicing slot 3, the splicing protrusion 2 is completely inserted into the splicing slot 3. During the insertion process of the splicing protrusion 2, the round head 505 will be squeezed, causing the push rod 503 to retract. When the circular groove 202 moves to the position of the round head 505, through the elastic action of the limiting spring 504, the round head 505 is tightly pressed against the circular groove 202 to realize the positioning and fixing function. It is convenient for combination and fixing, and the operation is simple and convenient. When disassembly is required, since the round head 505 is circular, one side of one wall panel body 1 can be hammered with a rubber hammer, so that the splicing protrusion 2 slides in the splicing slot 3, thereby separating the two wall panel bodies 1;

[0055] The closed compensation component 6 includes a rectangular sliding groove 601, a circular groove 602, a contact slider 603, a connecting rod 604, a compensation spring 606 and a fixed cylinder 608.

A contact slider 603 is slidably connected to the rectangular sliding groove 601, and inclined surfaces are provided on both sides of the contact slider 603;

[0056] One end of a connecting rod 604 is fixedly connected to a side wall of the contact slider 603. The other end of the connecting rod 604 extends to the circular groove 602. A connecting circular plate 605 is fixedly connected to one end of the connecting rod 604. The connecting circular plate 605 is slidably matched with the circular groove 602;

[0057] A fixed cylinder 608 is fixedly connected to the inner wall of the circular groove 602. A moving piston 609 is slidably connected to the inner cavity of the fixed cylinder 608. One end of a push rod 610 is fixedly connected to one side of the moving piston 609.

A circular plate 607 is fixedly connected to one end of the push rod 610. The circular plate 607 is slidably matched with the circular groove 602. A compensation spring 606 is fixedly connected between the circular plate 607 and the connecting circular plate 605. An inner cavity is provided inside the rubber gasket 4. One end of a connecting pipe 611 is fixedly connected to the inner cavity of the fixed cylinder 608. The other end of the connecting pipe 611 is fixedly connected to the inner cavity of the rubber gasket 4. Through this technical solution, when the wall panel bodies 1 are assembled and combined with each other, after the splicing protrusion 2 enters the splicing slot 3, the contact slider 603 will be extruded, so that the contact slider 603 moves into the rectangular sliding groove 601, thereby driving the connecting rod 604 to move, and further pushing the connecting circular plate 605 to move, so that the compensation spring 606 is compressed. The elastic force generated by the continuous compression of the compensation spring 606 can transmit the force to the push rod 610, and then push the moving piston 609 to move, so that the gas in the inner cavity of the fixed cylinder 608 is transported to the inner cavity of the rubber gasket 4 through the connecting pipe 611, so that the rubber gasket 4 expands sufficiently, and further can seal the joint, achieving a good sealing effect. At the same time, when the wall panel body 1 shrinks, the gap will increase. The elastic force generated by the continuous compression of the compensation spring 606 will further push the moving piston 609, so that the rubber gasket 4 expands further, playing a compensating role, and avoiding the problem of reduced sealing performance caused by the expansion of the gap.

[0058] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
