Description
Technical Field
The utility model relates to the technical field of sealing elements, in particular to a double-layer sound insulation sealing strip.
Background
As shown in fig. 2 and 3, a circle of door seam adhesive tape 1003 is adhered to the inner side of the periphery 1002 of the door frame of the automobile door 1001, so that when the door is closed, the impact force, the sound insulation and the sealing performance between the door and the automobile body are reduced;
as shown in fig. 4, the currently commonly used gate seam adhesive tape 1003 is a single-layer rubber sealing strip with a thickness less than 2mm, and the gate seam adhesive tape 1003 of the structure generally has the following disadvantages in practical application: firstly, when the automobile door frame 1001 is closed, the impact sound of the automobile door frame 1001 and the carriage door frame makes a sound, and if the force for closing is small, the automobile door frame 1001 cannot be bent and closed; secondly, the single-layer type door seam adhesive tape 1003 has poor sound insulation effect; thirdly, the sealing effect is not very good.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a double-layer sound-insulation sealing strip for solving the problems, and belongs to a noise-reduction door seam adhesive tape for a vehicle door, which comprises a sealing strip body with a double-layer structure, wherein the sealing strip body is an integral silicon rubber integral stretching piece, the lower end of the sealing strip body is provided with adhesive connected with the periphery of a door frame of a vehicle door frame, the main body of the sealing strip body is provided with a lower sealing strip, the upper end of the lower sealing strip is provided with an upper sealing strip, the upper sealing strip and the lower sealing strip are integrally connected, a plurality of inner cavities are respectively arranged in the lower sealing strip and the upper sealing strip, and the number of the inner cavities in the upper sealing strip is smaller than that of the inner cavities in the lower sealing strip.
The double-layer sound insulation sealing strip comprises a sealing strip body with a double-layer structure, wherein the sealing strip body is an integral silicon rubber integral stretching piece, and the lower end of a sealing strip main body is provided with adhesive;
the sealing strip body is provided with a lower sealing strip, the upper end of the lower sealing strip is provided with an upper sealing strip, and the upper sealing strip and the lower sealing strip are integrally connected;
a plurality of inner cavities are formed in the lower sealing strip, a plurality of inner cavities are formed in the upper sealing strip, and the number of the inner cavities formed in the upper sealing strip is smaller than that of the inner cavities formed in the lower sealing strip.
Further, three inner cavities are arranged in the lower sealing strip.
Further, two inner cavities are arranged in the upper sealing strip.
The beneficial effects of the utility model are:
the double-layer structure adopts the adhesive to be fixed on the periphery of the door frame along the ring, so that elastic deformation and buffer sealing can be realized to a greater extent, the air in the inner cavity can be effectively subjected to noise reduction and sound insulation, and the problems of noise and vibration when the conventional sealing strip is closed are solved.

In the figure: sealing strip body 1, sealing strip main part 2, paste and glue 3, upper seal strip 4, lower seal strip 5, inner chamber 6, car door frame 1001, door frame periphery 1002, crack adhesive tape 1003.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in figure 1, the double-layer sound insulation sealing strip comprises a sealing strip body 1 with a double-layer structure, belongs to a noise reduction door seam adhesive tape of a vehicle door, the sealing strip body 1 with the double-layer structure is an integral silicon rubber integral stretching piece, the lower end of the sealing strip body is provided with an adhesive 3 connected with the periphery of a door frame of a vehicle door frame, a sealing strip main body 1 is provided with a lower sealing strip 5, the upper end of the lower sealing strip 5 is provided with an upper sealing strip 4, the upper sealing strip 4 and the lower sealing strip 5 are integrally connected, and a plurality of inner cavities 6 are arranged in the sealing strip body, the width of the lower sealing strip 5 is larger than that of the upper sealing strip 4, and the number of the inner cavities 6 in the upper sealing strip 4 is smaller than that of the inner cavities 6 in the lower sealing strip 5.
When the concrete implementation is used, install the adhesion formula at the back that 3 outer protective films of 3 are glued in the subsides of the 5 lower extremes of sealing strip body 1, 3 glue of gluing are pasted the formula and are pasted the installation along door frame periphery 1002, including the lower sealing strip 5, top sealing strip 4 is outwards, when the door of car, when closing, door frame inboard periphery and sealing strip body 1 interior top sealing strip 4 elastic contact who contains inner chamber 6 coincide, the elastic deformation adjustment of inner chamber 6 ability self-adaptation that has the contractility, avoided car door and car door frame to produce great impact sound, 1001 fine syllable-dividing effect plays, the noise of closing the door has also been absorbed greatly to the air that persists in the inner chamber 6 simultaneously.
The setting of 1 bilayer structure of sealing strip body establishes the inner chamber 6 that can reserve the air in, fine play fall make an uproar and syllable-dividing function, noise and great vibration problem when also having avoided conventional sealing strip to close the door simultaneously.
