Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing strips, in particular to a beveled edge sealing strip. Background Art
[0002] Office silent warehouse doors are generally soundproofed by setting sealing strips. The existing technical solution is to use D-shaped sealing strips made of a single material such as PVC and EVA, and the back side of the sealing strips is glued to the door body. The defect is that it cannot solve the two major problems of sound insulation effect and door closing feel (i.e. shock absorption effect) at the same time. If the sound insulation effect is good, the hardness of the sealing strip needs to be about 60 Shore A, but at this time, closing the door requires relatively large force; and if the door closing feel is appropriate, the hardness of the sealing strip needs to be about 20 Shore A, but the sound insulation effect is not up to standard. In this context, the applicant is committed to researching a beveled edge sealing strip that achieves both good sound insulation effect and good shock absorption effect. Utility Model Content
[0003] The purpose of the utility model is to achieve both good sound insulation effect and good shock absorption effect.
[0004] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:
[0005] A beveled sealing strip comprises a dense portion and a foamed portion, wherein the interior of the dense portion is hollow and its cross-section is rectangular, and the foamed portion comprises a straight-edge strip and a beveled strip, one side of the straight-edge strip and one side of the beveled strip are integrally formed, and the other side of the straight-edge strip and the other side of the beveled strip are respectively integrally formed on an outer side of the dense portion, and the beveled strip protrudes outward, the dense portion is densely made of EPDM rubber, and the foamed portion is foamed by EPDM rubber.
[0006] Furthermore, the side surface of the dense portion is integrally formed with an anti-slip raised strip.
[0007] Furthermore, there are three anti-slip raised strips, and the cross section of the anti-slip raised strips is semicircular.
[0008] Furthermore, the radius of the anti-slip raised strip is in the range of 0.3-0.8 mm.
[0009] Furthermore, the wall thickness of the inclined rubber strip of the foaming portion is in the range of 1.2-1.3 mm, and the wall thickness of the straight-edge rubber strip is in the range of 1.3-1.5 mm.
[0010] Furthermore, the hardness of the foamed portion is 20 Shore A.
[0011] Furthermore, the wall thickness of the dense portion ranges from 1.8 to 2 mm.
[0012] Furthermore, the hardness of the dense portion is 60 Shore A.
[0013] Furthermore, the surface of the bevel rubber strip is sprayed with tactile oil.
[0014] The beneficial effects of the present invention are as follows: the present invention forms the dense part and the foamed part into one piece by setting a dense part and a foamed part, and the dense part is made of EPDM rubber by dense molding, and the foamed part is made of EPDM rubber by foaming, so that the dense part has a higher density and a higher hardness, making its texture harder, while the foamed part has a lower density and a lower hardness, making its texture softer. After the present invention is pasted on the door body, when closing the door, the door body squeezes the foamed part with a softer texture, thereby obtaining a better shock-absorbing effect. People can clearly feel the good door closing feel produced when squeezing the foamed part. When the door is completely closed, the door body squeezes the foamed part on the dense part, and sound insulation between the door body and the wall is achieved through the dense part, thereby achieving good sound insulation effect through the dense part. Compared with the sealing strip with a single hardness used in traditional technology, the present invention achieves the purpose of having both good sound insulation effect and good shock absorption effect.

[0017] The accompanying drawings are:
[0018] Dense part 1, foaming part 2, straight edge rubber strip 21, inclined rubber strip 22, anti-slip raised strip 3. DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figure 1 、 Figure 2 The beveled edge sealing strip shown includes a dense portion 1 and a foamed portion 2.
[0021] The interior of the dense part 1 is hollow and its cross-section is rectangular. The foaming part 2 includes a straight-edge rubber strip 21 and a bevel rubber strip 22. One side of the straight-edge rubber strip 21 and one side of the bevel rubber strip 22 are integrally formed, and the other side of the straight-edge rubber strip 21 and the other side of the bevel rubber strip 22 are respectively integrally formed on an outer side of the dense part 1, that is, the dense part 1 and the foaming part 2 are integrally formed.
[0022] The inclined rubber strip 22 protrudes outwards, and when closing the door, a better shock-absorbing effect and a better door-closing feel are obtained through the protruding inclined rubber strip 22 .
[0023] The dense part 1 is made of EPDM rubber, and the foamed part 2 is made of EPDM rubber, so that the dense part 1 has a higher density and a higher hardness, making its texture harder, while the foamed part 2 has a lower density and a lower hardness, making its texture softer.
[0024] The side of the dense portion 1 is integrally formed with anti-slip raised strips 3. There are three anti-slip raised strips 3, and the cross section of the anti-slip raised strips 3 is semicircular. The radius of the anti-slip raised strips 3 is in the range of 0.3-0.8 mm.
[0025] The purpose of designing the anti-slip raised strip 3 is to replace the double-sided tape for installation. The advantage of the EPDM rubber material is its long service life. Such a structural design makes the utility model firmly installed and not easy to fall off, easy to install and durable.
[0026] The wall thickness of the inclined rubber strip 22 of the foaming part 2 is in the range of 1.2-1.3mm, the wall thickness of the straight-edge rubber strip 21 is in the range of 1.3-1.5mm, and the hardness of the foaming part 2 is 20Shore A; the wall thickness of the dense part 1 is in the range of 1.8-2mm, and the hardness of the dense part 1 is 60Shore A. This design can ensure the qualified sealing and sound insulation effect when closing the door. At the same time, the hardness is very soft, and the contact surface between the rubber strip and the glass can be deformed to a large extent, so no great force is required when closing the door.
[0027] After the utility model is pasted on the door body, when closing the door, the door body squeezes the softer foaming part 2, thereby obtaining a better shock-absorbing effect. People can clearly feel the good door closing feel produced when squeezing the foaming part 2. When the door is completely closed, the door body squeezes the foaming part 2 on the dense part 1, and the sound insulation between the door body and the wall is achieved through the dense part 1, thereby achieving a good sound insulation effect through the dense part 1.
[0028] The surface of the bevel rubber strip 22 is sprayed with tactile oil. The surface of the bevel rubber strip 22 is first treated with a plasma processor, which can greatly improve the surface wettability, form an active surface and remove dust and oil. Fine cleaning and destaticization improve the surface adhesion ability, improve the reliability and durability of the surface bonding, and then the tactile oil is sprayed on the surface of the bevel rubber strip 22 to make the surface soft and glossy, while improving the surface waterproof and oil-proof properties.
[0029] When installing the utility model at a corner, the corner portion of the utility model is set to a circular arc transition shape and is manufactured in an integrated molding manner using a corner joint machine, so that the overall shape fits more closely to the door body installation groove, ensuring the flatness, practicality and aesthetic requirements of the corner portion after installation.
[0030] The working principle of the present invention is: after the present invention is pasted on the door body, when closing the door, the door body squeezes the softer foaming part 2, thereby obtaining a better shock absorption effect. People can clearly feel the good door closing feel produced when squeezing the foaming part 2. When the door is completely closed, the door body squeezes the foaming part 2 on the dense part 1, and the sound insulation between the door body and the wall is achieved through the dense part 1, thereby achieving a good sound insulation effect through the dense part 1.

Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention. The above does not impose any limitation on the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
