Description

Technical Field

[0001] This utility model relates to the technical field of car door sealing strip structure, and in particular to a fluororubber car door sealing strip structure. Background Technology

[0002] Fluororubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Door sealing strips are used between the door and the body to prevent wind, rain, water and dust from entering the car. They also act as a buffer when the door is closed and to prevent the door from vibrating when the car is in motion.

[0003] In existing automotive door sealing strip assembly technologies, snap-on installation and tape bonding are generally used. However, these methods are prone to deformation and detachment during prolonged use, affecting the sealing performance. Therefore, we propose a fluororubber door sealing strip structure. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a fluororubber door sealing strip structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fluororubber car door sealing strip structure, including a snap-fit ​​part, the snap-fit ​​part having a hollow rectangular cross-section, a protrusion fixedly installed on the side of the snap-fit ​​part, the protrusion having a rectangular cross-section, a pressing part fixedly installed on the side of the protrusion away from the snap-fit ​​part, a pressing side fixedly installed on the side of the pressing part, two symmetrically formed edge-fitting edges on the side of the protrusion, the edge-fitting edges having an arc-shaped cross-section, a guide cavity opened on the inner side of the snap-fit ​​part corresponding to the edge-fitting edge, a pressing cavity opened on the side of the guide cavity, a movable pressing structure provided inside the guide cavity and the pressing cavity, and a pressing part with an arc-shaped cross-section fixedly installed on the side of the pressing part corresponding to the edge-fitting edge.

[0006] Preferably, the extrusion structure includes a first support portion fixedly installed inside the snap-fit ​​portion, a first extrusion block fixedly installed on one side of the first support portion corresponding to the position of the guide cavity, and a second extrusion block fixedly installed on one end of the first extrusion block corresponding to the position of the extrusion cavity.

[0007] Preferably, a second support is fixedly installed inside the extrusion part, and the cross-section of the second support is "W".

[0008] Preferably, the cross-section of the extrusion section is an inverted "D" shape.

[0009] Preferably, both the side of the snap-fit ​​portion and the side of the compression portion are provided with circular vent holes.

[0010] Preferably, the outer sides of the snap-fit ​​portion, the extrusion portion, and the extrusion side are all coated with a wear-resistant and sound-absorbing coating.

[0011] Beneficial effects

[0012] This invention provides a fluororubber door sealing strip structure. It has the following advantages:

[0013] (1) The structure of the fluororubber door sealing strip is such that the snap-fit ​​part is snapped into the slot of the door where the sealing strip is specially installed, the protrusion extends out from the slot where the sealing strip is specially installed, and the edge is tightly attached to the outside of the slot where the sealing strip is specially installed. When the door is closed, the door squeezes the squeezing part, and the squeezing part drives the pressing part to squeeze one side of the edge. When the squeezing part squeezes the snap-fit ​​part, the squeezing structure squeezes the inside of the snap-fit ​​part to improve the sealing effect. Attached Figure Description

[0022] like Figures 1-3 As shown, a fluororubber door sealing strip structure includes a snap-fit ​​part 1, which has a hollow rectangular cross-section. A protrusion 2, also rectangular in cross-section, is fixedly installed on the side of the snap-fit ​​part 1. A compression part 3, with an inverted "D" shaped cross-section, is fixedly installed on the side of the protrusion 2 away from the snap-fit ​​part 1. Circular vent holes are provided on both the side of the snap-fit ​​part 1 and the side of the compression part 3. A compression side edge 4 is fixedly installed on the side of the compression part 3. Two symmetrically arranged edges 10, arc-shaped in cross-section, are provided on the side of the snap-fit ​​part 1 corresponding to the edge 10. A compression cavity 6 is provided on the side of the guide cavity 5. Movable compression structures are provided inside the guide cavity 5 and the compression cavity 6. A pressing part 11 with an arc-shaped cross section is fixedly installed on the side of the pressing part 3 corresponding to the edge 10. When in use, an adhesive is sprayed inside the slot for installing the sealing strip, and the snap-fit ​​part 1 is snapped into the slot for installing the sealing strip on the car door. The protrusion 2 extends out from the slot for installing the sealing strip. The edge 10 is tightly attached to the outside of the slot for installing the sealing strip. When the car door is closed, the car door presses the pressing part 3. The pressing part 3 drives the pressing part 11 to press one side of the edge 10. When the pressing part 3 presses the snap-fit ​​part 1, it presses the inside of the snap-fit ​​part 1 through the pressing structure to improve the sealing effect. The snap-fit ​​part 1, the pressing part 3 and the outside of the pressing side 4 are all sprayed with a wear-resistant and sound-absorbing coating.

[0023] The extrusion structure includes a first support 9 fixedly installed inside the snap-fit ​​part 1. A first extrusion block 7 is fixedly installed on one side of the first support 9 corresponding to the position of the guide cavity 5. A second extrusion block 8 is fixedly installed on one end of the first extrusion block 7 corresponding to the position of the extrusion cavity 6. Through the first support 9, the first extrusion block 7 and the second extrusion block 8, the side wall of the snap-fit ​​part 1 is pressed tightly against the inside of the slot for installing the sealing strip during the extrusion process. A second support 12 is fixedly installed inside the extrusion part 3. The second support 12 has a "W" shaped cross section and supports the inside of the extrusion part 3.

[0024] The working principle of this utility model:

[0025] During use, adhesive is sprayed inside the slot for installing the sealing strip. The snap-fit ​​part 1 is then snapped into the slot for installing the sealing strip on the car door. The protrusion 2 extends out from the slot for installing the sealing strip, and the edge 10 is tightly attached to the outside of the slot for installing the sealing strip. When the car door is closed, the door presses against the compression part 3. The compression part 3 drives the pressing part 11 to press against one side of the edge 10. When the compression part 3 presses against the snap-fit ​​part 1, it uses the compression structure to press against the inside of the snap-fit ​​part 1 to improve the sealing effect. The first support part 9, the first compression block 7, and the second compression block 8 ensure that the side wall of the snap-fit ​​part 1 is tightly attached to the inside of the slot for installing the sealing strip during the compression process. The second support part 12 provides support for the inside of the compression part 3.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
