Description

Technical Field

[0001] This utility model relates to the field of soundproof door technology, specifically a safety door with soundproofing effect. Background Technology

[0002] Soundproof doors primarily serve to insulate against noise, preventing the most direct harm to the human body from noise, which is hearing damage. This noise then affects the central nervous system, causing neurasthenia problems such as headaches, insomnia, and memory loss.

[0003] However, existing soundproof doors are not very effective at blocking external noise, allowing noise to spread. They also make noise when opening and closing, which can affect the sleep of sensitive people. Utility Model Content

[0004] The purpose of this invention is to provide a safety door with sound insulation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soundproof security door, including

[0007] The outer door panel has several arc-shaped grooves on both sides of the center of the front side, and the distance between the arc-shaped grooves is equal. The two corners of the front side of the outer door panel are provided with buffer components. The inner door body is fixedly connected to the back side of the outer door panel.

[0008] The interior door has a rectangular groove inside, an I-shaped frame inside the rectangular groove, and a square groove inside the I-shaped frame. Several noise reduction components are installed inside the square groove. Both sides of the top of the interior door have vertically penetrating pipe grooves, and sound insulation components are installed inside the pipe grooves.

[0009] Preferably, the noise reduction component includes a tenon column and a blocking block. The top of the tenon column is interference-fitted to the inner top of the I-shaped frame. The bottom of the tenon column is fixedly connected to the blocking block. The bottom of the blocking block has a mortise, the size of which matches the tenon column. Several slots are formed on both sides of the top of the blocking block. A rubber block is placed inside the slot. A through groove is formed inside the rubber block. An arc-shaped damping block is interference-fitted to the inner side wall of the through groove. A damping connecting block is fixedly connected to the side of the arc-shaped damping block opposite to the through groove. A damping tube is fixedly connected to the side of the damping connecting block opposite to the arc-shaped damping block. A damping strip is fixedly connected inside the damping tube.

[0010] Preferably, the sound insulation component includes a metal sheet and an air cushion. One side of the metal sheet is fixedly connected to the inner wall of one side of the pipe groove, and the other side of the metal sheet is fixedly connected to the air cushion. A rubber column is provided on the side of the air cushion facing away from the metal sheet.

[0011] Preferably, the buffer assembly includes a connecting block and a U-shaped sponge pad. One end of the connecting block is fixedly connected to the front corner of the outer door panel, and the other end of the connecting block is fixedly connected to the U-shaped sponge pad, with a compression airbag provided in the middle of the U-shaped sponge pad.

[0012] Preferably, there is a gap between the outer surface of the barrier block and the inner walls of both sides of the I-shaped frame, and the gap is filled with sound-absorbing cotton.

[0013] Preferably, a door lock structure is provided on one side of the front of the outer door panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This type of soundproof security door uses a combination of sound-insulating blocks and mortise and tenon joints. In use, the sound-insulating blocks are interlocked using these joints and mortises. The two beveled surfaces at the bottom form an angle with the empty flat surface. This angle effectively disperses and blocks sound. When sound vibrates and penetrates the surface of the sound-insulating block, it is reflected by the beveled surfaces. The sound-absorbing cotton then absorbs the remaining sound wave energy. If absorption is insufficient, the empty flat surface of the sound-insulating block receives the remaining sound wave energy and reflects it again.

[0016] This type of soundproof security door, through the setting of damping connecting strips and damping tubes, when the door is impacted, the blocking blocks are squeezed against each other, and the friction between the blocking blocks is mitigated by rubber blocks, preventing the mortise and tenon columns at the top from breaking in the mortise. At the same time, the arc-shaped damping blocks set inside the rubber blocks can receive kinetic energy, and the setting of damping connecting strips, damping tubes and damping strips reduces resonance. The damping connecting strips are used to transmit force, the damping tubes can deform to buffer and reduce vibration, and the damping strips prevent the damping tubes from deforming excessively, thereby achieving buffering of external impact forces.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 As shown, this utility model provides a technical solution:

[0027] A soundproof security door, including

[0028] The outer door panel 1 has several arc-shaped grooves 2 on both sides of the center of the front of the outer door panel 1, and the distance between the arc-shaped grooves 2 is equal. The two corners of the front of the outer door panel 1 are provided with buffer components. The back of the outer door panel 1 is fixedly connected to the inner door body 3.

[0029] Please refer to the attached document for details. Figure 1 The outer door panel 1 is made of metal plate, and combined with several arc-shaped grooves 2 on its surface, when the sound encounters the outer door panel 1, its relatively hard metal material can reflect the sound well. Furthermore, the dense arc-shaped grooves 2 on the surface of the outer door panel 1 can increase the number of reflections, thereby reducing the sound penetration.

[0030] Furthermore, the outer door panel 1 can increase the overall mass of the door, and according to the law of mass, the greater the mass of the door, the better the sound insulation effect is usually;

[0031] The inner door body 3 has a rectangular groove inside, and an I-shaped frame 4 is installed inside the rectangular groove. The I-shaped frame 4 has a square groove inside, and several noise reduction components are installed inside the square groove. Both sides of the top of the inner door body 3 have vertically penetrating pipe grooves, and sound insulation components are installed inside the pipe grooves.

[0032] Please refer to the attached document for details. Figure 1 and attached Figure 2 The inner door body 3 is composed of two metal plates, and the surface of the inner door body 3 is also fitted with a door shell. The outer door panel 1 and the four edges of the door shell are all equipped with sealing strips. The sealing strips are PU-coated sealing strips to reduce the transmission of sound through the gap between the door and the door frame, so as to further isolate noise.

[0033] Furthermore, the outer door panel 1, inner door body 3, I-beam frame 4, and door shell are all made of metal plates (including but not limited to: cold-rolled steel plates, stainless steel) or composite materials, and are all installed using existing threaded bolts. The inner door body 3 and I-beam frame 4 both adopt a double-layer steel plate structure, and a damping sound insulation plate is filled between the inner door body 3 and I-beam frame 4 to absorb and dissipate vibration energy and reduce material resonance. When sound waves cause the material to vibrate, the damping material will convert the vibration energy into heat energy, thereby reducing the propagation of sound.

[0034] In this embodiment, preferably, the noise reduction component includes a tenon column 5 and a blocking block 6. The top of the tenon column 5 is interference-connected to the inner top of the I-shaped frame 4. The bottom of the tenon column 5 is fixedly connected to the blocking block 6. The bottom of the blocking block 6 is provided with a mortise, and the size of the mortise matches that of the tenon column 5. Several slots are provided on both sides of the top of the blocking block 6. A rubber block 7 is provided inside the slot. A through groove is provided inside the rubber block 7. An arc-shaped damping block 8 is interference-connected to the inner side wall of the through groove. A damping connecting strip 9 is fixedly connected to the side of the arc-shaped damping block 8 away from the through groove. A damping tube 10 is fixedly connected to the side of the damping connecting strip 9 away from the arc-shaped damping block 8. A damping strip 11 is fixedly connected inside the damping tube 10.

[0035] Please refer to the attached document for details. Figure 2 Appendix Figure 4 and attached Figure 5 There are several blocking blocks 6, which are connected and combined with each other through the setting of mortise and tenon columns 5 and mortise holes. At the same time, the blocking block 6 is specifically composed of two equilateral triangles of different sizes that are inverted and combined with each other. That is, the outer surface of the blocking block 6 has four inclined planes with an inclination of 60 degrees.

[0036] In this embodiment, preferably, there is a gap between the outer surface of the barrier block 6 and the inner walls of both sides of the I-shaped frame 4, and the gap is filled with sound-absorbing cotton 17.

[0037] Please refer to the attached document for details. Figure 2 and attached Figure 3 The gap between the outer surface of the blocking block 6 and the I-beam frame 4 is filled with high-density sound-absorbing cotton 17 (including but not limited to: rock wool, glass fiber, polyester fiber, etc.). Through the porous structure of the sound-absorbing cotton 17, sound wave energy is effectively absorbed and sound propagation is reduced.

[0038] Specifically, the blocking block 6 is made of solid wood. Its upper sloping surface is covered by the mortise and tenon joint 5 and the mortise. After the blocking block 6 is assembled, it fits tightly. Its remaining two sloping surfaces and the empty plane will form an angle. By setting this angle, it can play the role of differentiating and blocking sound. That is, when the sound penetrates into the surface of the blocking block 6 through vibration, it will be reflected by the sloping surface. The sound-absorbing cotton 17 will absorb the residual sound wave energy again. If it is still not completely absorbed, the empty plane of the blocking block 6 will receive the remaining sound wave energy and reflect it again.

[0039] Furthermore, when the entire door is subjected to a violent impact from the outside to the inside, the outer door panel 1 absorbs the force and transmits the remaining force to the inner door body 3. The inner door body 3 further weakens the force and then transmits it to the damping sound insulation board. The damping sound insulation board absorbs and dissipates vibration energy, reduces material resonance, and greatly weakens the impact force. Then, the residual force is transmitted through the sound-absorbing cotton 17 to the surface of the blocking block 6. The blocking block 6 vibrates under the force. At this time, the blocking blocks 6 are prone to squeezing each other. When squeezing, the rubber block 7 set in the slot at the top of the blocking block 6 eases the friction between the blocking blocks 6 and prevents the mortise and tenon at the top from breaking in the mortise.

[0040] Furthermore, if the force is too great and the properties of the rubber block 7 itself are insufficient to mitigate the energy generated by the vibration, the arc-shaped damping block 8 inside it will receive the kinetic energy immediately and reduce resonance through the setting of the damping connecting strip 9, the damping tube 10 and the damping strip 11. The damping connecting strip 9 is used to transmit force, the damping tube 10 can deform to buffer and reduce vibration, and the damping strip 11 prevents the damping tube 10 from deforming excessively, thereby achieving buffering of external impact force.

[0041] In this embodiment, preferably, the sound insulation component includes a metal sheet 12 and an air cushion 18. One side of the metal sheet 12 is fixedly connected to the inner wall of one side of the pipe groove, and the other side of the metal sheet 12 is fixedly connected to the air cushion 18. A rubber column 13 is provided on the side of the air cushion 18 facing away from the metal sheet 12.

[0042] Please refer to the attached document for details. Figure 2 and attached Figure 6 The metal sheet 12 is made of the same material as the I-beam frame 4 mentioned above, so it will not be described in detail here. Meanwhile, the air cushion 18 is a rubber pad that is injected with air. It is not very hard but has toughness. The rubber column 13 is a column made of rubber, which is existing and will not be described in detail here.

[0043] Understandably, when the portal is subjected to external force, after the external force is absorbed by multiple structural buffers, the remaining sound wave energy generated by the force will continue to radiate and diffuse through the I-beam frame 4 as a carrier. The propagation efficiency will be reduced by the rubber column 13, and then received by the air cushion 18. The compressibility and elasticity of the gas inside the air cushion 18 can absorb and disperse the sound wave energy. Finally, the remaining sound wave will be reflected by the metal plate 12 and absorbed and dispersed again by the air cushion 18. In addition, the metal plate 12 can also reflect the sound outside the door, and together with the sealing strip, further prevent noise from seeping in.

[0044] In this embodiment, preferably, the buffer assembly includes a connecting block 14 and a U-shaped sponge pad 15. One end of the connecting block 14 is fixedly connected to the front corner of the outer door panel 1, and the other end of the connecting block 14 is fixedly connected to the U-shaped sponge pad 15. A compression airbag 16 is provided in the middle of the U-shaped sponge pad 15.

[0045] Please refer to the attached document for details. Figure 1 and attached Figure 7 A connecting block 14 is glued to one corner of the front edge of the outer door panel 1. The side of the connecting block 14 facing away from the outer door panel 1 has an installation hole. A U-shaped sponge pad 15 folded into a U-shape is inserted into the installation hole and is glued to fix it in place to prevent it from falling off the connecting block 14. At the same time, a compression airbag 16 is inserted at the fold of the U-shaped sponge pad 15.

[0046] Understandably, if the door slips out of your hand when it is opened, the outer surface of the door and the handle will collide with the wall due to inertia. At this time, the U-shaped sponge pad 15 can buffer the force of the collision, and the compression airbag 16 can absorb the kinetic energy. The overall thickness of the connecting block 14 and the U-shaped sponge pad 15 is higher than that of the door handle, so it will contact the wall before the door handle during the collision.

[0047] In this embodiment, preferably, a door lock structure is provided on one side of the front of the outer door panel 1.

[0048] In this embodiment, a safety door with sound insulation effect can effectively reflect sound through the relatively hard metal material of the outer door panel 1. The dense arc-shaped grooves 2 on the surface of the outer door panel 1 can increase the number of reflections, thereby reducing sound penetration. Subsequently, the sealing strip reduces the transmission of sound through the gap between the door and the door frame, so as to further isolate noise. The damping sound insulation board filled between the inner door body 3 and the I-beam frame 4 is used to absorb and dissipate vibration energy and reduce material resonance.

[0049] Furthermore, by setting the angle of the blocking block 6, it can achieve the effect of separating and blocking sound. That is, when sound penetrates into the surface of the blocking block 6 through vibration, it will be reflected by the obstruction of the inclined surface, and the residual sound wave energy will be absorbed again by the sound-absorbing cotton 17. If it is still not completely absorbed, the empty plane of the blocking block 6 will receive the remaining sound wave energy and reflect it again.

[0050] At the same time, the barrier blocks 6 press against each other. When they are pressed, the rubber block 7 set in the slot at the top of the barrier block 6 can alleviate the friction between the barrier blocks 6 and prevent the mortise and tenon at the top from breaking in the mortise.

[0051] In addition, the damping connecting strip 9 can transmit force, the damping tube 10 can deform to buffer and reduce vibration, and the damping strip 11 prevents the damping tube 10 from deforming excessively, thereby achieving buffering of external impact forces.

[0052] Finally, if the door slips out of your hand when it is opened, the outer surface of the door and the handle will collide with the wall due to inertia. At this time, the U-shaped sponge pad 15 can buffer the force of the collision, and the compression airbag 16 can absorb its kinetic energy. The overall thickness of the connecting block 14 and the U-shaped sponge pad 15 is higher than that of the door handle, so it will contact the wall before the door handle during the collision.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
