Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, specifically to an ultra-soundproof polypropylene sealing strip. Background Technology

[0002] A sealing strip is a product used to seal something, making it difficult to open, and serving functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials, including rubber, paper, metal, and plastic. In modern construction, automobile manufacturing, home appliance production, and many other fields, sealing strips are widely used in the gaps of doors, windows, and enclosures, playing a vital role in sealing, sound insulation, and shock absorption. As people's demands for quality of life and working environment continue to increase, higher requirements are being placed on the sound insulation performance and ease of installation of sealing strips.

[0003] In terms of sound insulation performance, most existing sealing strips are made of ordinary rubber or plastic materials. Their internal structure lacks effective sound insulation design and cannot effectively block the transmission of sound. As a result, in noisy environments, such as buildings near roads or airports, or inside cars traveling at high speeds, noise can still enter the room or car through the gaps, affecting people's comfort and work efficiency.

[0004] Traditional sealing strip connection methods require the use of glue to bond the sealing strips at both ends. Installers not only need to precisely control the amount of glue used, but also need to ensure that it is applied evenly. Slight carelessness may lead to an unstable connection or poor sealing effect. The connection method is cumbersome and requires installers to have certain professional skills, which greatly reduces work efficiency. To address this, a super soundproof polypropylene sealing strip is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-soundproof polypropylene sealing strip to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a super soundproof polypropylene sealing strip, comprising a sealing strip body, wherein a first through groove and a second through groove are respectively opened inside the sealing strip body, and the inner sides of the first through groove and the second through groove are filled with sound-absorbing cotton, wherein the sound-absorbing cotton is used to block sound transmission.

[0007] Both sides of the sealing strip body are integrally formed with protrusions, and there are several protrusions. One end of the sealing strip body is provided with a guide head.

[0008] One end of the sealing strip body is provided with a connecting component, which is used to connect any two sealing strip bodies;

[0009] The connecting assembly includes a connecting rod and a support frame. The support frame has an insertion slot inside, and a first arc-shaped frame is fixed on both sides of the connecting rod.

[0010] Preferably, the above-mentioned first arc-shaped frame on both sides is two in number, and a first guide slope is provided on one side of the first arc-shaped frame.

[0011] Preferably, one side of the connecting rod is fixed to one end of the sealing strip body, and the outer side of the support frame is fixedly embedded in the other end of the sealing strip body.

[0012] Preferably, the first arc-shaped frame has a rounded corner at one end.

[0013] Preferably, the support frame has a second arc-shaped frame fixed on both sides of its inner wall, and a second guide slope is provided on one side of the second arc-shaped frame.

[0014] Preferably, the first guide slope and the second guide slope are inclined in opposite directions, and when the connecting rod is inserted into the insertion slot, the first arc-shaped frame and the second arc-shaped frame are in a snap-fit ​​state.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] The sealing strip is made of polypropylene, with a first and second through groove inside and filled with sound-absorbing cotton. When sound travels to the sealing strip, the sound-absorbing cotton can absorb and block the sound transmission. Some sound waves are absorbed, reducing the continued propagation of sound, effectively reducing the entry of external noise or the transmission of internal sound, creating a quiet environment for indoor or specific spaces, and improving user comfort.

[0017] The sealing strip body has a guide head with a rounded end. When the sealing strip body is inserted into the sealing groove, the rounded end of the guide head acts as a guide, allowing the sealing strip body to slide more smoothly along the shape of the sealing groove, reducing installation resistance, improving installation efficiency, and reducing installation difficulty and cost. After the sealing strip body is installed in the sealing groove, the protrusion can make close contact with the inner wall of the sealing groove, increasing the friction and sealing between the two, effectively preventing air, moisture and other substances from entering from the gaps, playing a good sealing role, and protecting the internal environment from external factors.

[0018] During the connection process, simply insert the connecting rod of one sealing strip body into the support bracket insertion groove of another sealing strip body. Through the sliding fit of the first guide slope and the second guide slope, as well as the guiding effect of the rounded corners, the sealing strip bodies can be connected. The connection method is simple to operate, requires no complicated tools or professional skills, greatly shortens the installation time, and improves work efficiency. Attached Figure Description

Example

[0028] Please see Figure 1-5This utility model provides a technical solution: a super soundproof polypropylene sealing strip, including a sealing strip body 1, the sealing strip body 1 being made of polypropylene, a first through groove 6 and a second through groove 7 respectively opened inside the sealing strip body 1, the inner sides of the first through groove 6 and the second through groove 7 being filled with sound-absorbing cotton 5, the first through groove 6 and the second through groove 7 being a closed cavity structure, the inner side of which is sealed after being filled with sound-absorbing cotton 5, the sound-absorbing cotton 5 being made of polyester fiber, the sound-absorbing cotton 5 being used to block sound transmission; both sides of the sealing strip body 1 are integrally formed with protrusions 2, the number of protrusions 2 being several, one end of the sealing strip body 1 is provided with a guide head 4, the end of the guide head 4 being an arc surface, the guide head 4 being used to guide the sealing strip body 1 to be inserted into the inner side of the sealing groove; one end of the sealing strip body 1 is provided with a connecting component 3, the connecting component 3 being used to connect any two sealing strip bodies 1.

[0029] The connecting component 3 includes a connecting rod 32 and a support frame 36. The support frame 36 has an insertion slot 31 inside. A first arc frame 34 is fixed on both sides of the connecting rod 32. The radius of curvature of the first arc frame 34 is 1.2-1.5mm. The connecting rod 32, the support frame 36, the first arc frame 34 and the second arc frame 38 are all made of plastic. The first arc frame 34 and the second arc frame 38 have a certain deformation capacity due to the material.

[0030] There are two first arc-shaped frames 34 on each side. One side of the first arc-shaped frame 34 is provided with a first guide slope 33. One side of the connecting rod 32 is fixed to one end of the sealing strip body 1. The outer side of the support frame 36 is fixedly embedded in the other end of the sealing strip body 1. The fixing and embedding can be injection molding, adhesive or snap connection. One end of the first arc-shaped frame 34 is provided with a rounded corner 35. During the connection process, the first arc-shaped frame 34 will undergo a certain deformation. The elastic deformation allows the connection structure to adapt to certain installation errors and the slight deformation of the sealing strip body 1 during use, without affecting the firmness and sealing performance of the connection.

[0031] The support frame 36 has two second arc-shaped frames 38 fixed on both sides of its inner wall. The second arc-shaped frame 38 has a second guide slope 37 on one side. When the connecting rod 32 is inserted into the insertion groove 31, the first guide slope 33 slides on one side of the second guide slope 37. Then the first arc-shaped frame 34 passes over one side of the second arc-shaped frame 38. At this time, the rounded corner 35 plays a guiding role. Then the first arc-shaped frame 34 and the second arc-shaped frame 38 are respectively snapped together, thus completing the connection between the two sealing strip bodies 1. After the first arc-shaped frame 34 passes over the second arc-shaped frame 38, the two achieve stable snapping due to elastic recovery deformation, thereby completing the connection between the two sealing strip bodies 1. The structure can provide a stable connection force, so that the two sealing strip bodies 1 are tightly joined together and are not easy to loosen or fall off.

[0032] The first guide slope 33 and the second guide slope 37 have opposite inclination directions. When the connecting rod 32 is inserted into the inner side of the insertion groove 31, the first arc frame 34 and the second arc frame 38 are in a snap-fit ​​state. The sealing strip body 1 has a certain elasticity. The deformation capacity of the first arc frame 34 and the second arc frame 38 allows the two ends of the sealing strip body 1 to self-adjust during connection, so that the first arc frame 34 and the second arc frame 38 can be easily snapped together.

[0033] Working principle: The main body 1 of the sealing strip is made of polypropylene. It has a first through groove 6 and a second through groove 7 inside. The inner sides of the first through groove 6 and the second through groove 7 are filled with sound-absorbing cotton 5. When sound travels to the sealing strip, the sound-absorbing cotton 5 can absorb and block the transmission of sound. When the sound encounters the sound-absorbing cotton 5 during the propagation process, some sound waves will be absorbed by the sound-absorbing cotton 5, thereby reducing the continued propagation of sound and achieving the effect of super sound insulation.

[0034] One end of the sealing strip body 1 is provided with a guide head 4. The end of the guide head 4 is an arc surface. When the sealing strip body 1 is inserted into the sealing groove, the arc surface of the guide head 4 can play a guiding role. The guide head 4 allows the sealing strip body 1 to slide more smoothly into the sealing groove along the shape of the sealing groove, reducing the resistance during installation and facilitating the installation of the sealing strip body 1. After the sealing strip body 1 is installed in the sealing groove, the protrusion 2 can make close contact with the inner wall of the sealing groove, increasing the friction and sealing between the sealing strip body 1 and the sealing groove, preventing air, moisture and other substances from entering from the gap between the sealing strip body 1 and the sealing groove, thus playing a good sealing role.

[0035] When it is necessary to connect two sealing strip bodies 1 together, the connecting rod 32 of one sealing strip body 1 is inserted into the insertion groove 31 of the support frame 36 of the other sealing strip body 1. During the insertion process, the first guide slope 33 on one side of the first arc frame 34 will slide on the second guide slope 37 on one side of the second arc frame 38. Since the inclination direction of the first guide slope 33 and the second guide slope 37 are opposite, as the connecting rod 32 continues to be inserted, the first arc frame 34 will undergo a certain deformation under the action of the second guide slope 37. At the same time, the rounded corner 35 at one end of the first arc frame 34 plays a guiding role, making it easier for the first arc frame 34 to pass over the second arc frame 38. After the first arc frame 34 passes over the second arc frame 38, the first arc frame 34 and the second arc frame 38 will return to their original deformation, thereby achieving a snap-fit ​​connection and completing the connection between the two sealing strip bodies 1.

[0036] In summary, by using polypropylene material for the main body 1 of the sealing strip, and opening the first through groove 6 and the second through groove 7 inside and filling it with sound-absorbing cotton 5, when sound travels to the main body 1 of the sealing strip, the sound-absorbing cotton 5 can absorb and block the sound transmission. Some sound waves are absorbed, reducing the continued propagation of sound, effectively reducing the entry of external noise or the transmission of internal sound, creating a quiet environment for indoor or specific spaces, and improving the comfort of use.

[0037] The sealing strip body 1 has a guide head 4 with a rounded end. When the sealing strip body 1 is inserted into the sealing groove, the rounded end of the guide head 4 acts as a guide, allowing the sealing strip body 1 to slide more smoothly along the shape of the sealing groove, reducing installation resistance, improving installation efficiency, and reducing installation difficulty and cost. After the sealing strip body 1 is installed in the sealing groove, the protrusion 2 can make close contact with the inner wall of the sealing groove, increasing the friction and sealing between the two, effectively preventing air, moisture and other substances from entering from the gap, playing a good sealing role, and protecting the internal environment from external factors.

[0038] During the connection process, simply insert the connecting rod 32 of one sealing strip body 1 into the insertion groove 31 of the support frame 36 of another sealing strip body 1. Through the sliding fit of the first guide slope 33 and the second guide slope 37 and the guiding effect of the rounded corner 35, the sealing strip body 1 can be connected. The connection method is simple to operate, requires no complicated tools or professional skills, greatly shortens the installation time, and improves work efficiency.
