Description

Technical Field

[0001] This utility model relates to the field of cavity sealing technology, and in particular to a rotatable expansion block structure used in automotive sheet metal installation. Background Technology

[0002] During the installation of expansion rubber blocks onto sheet metal, because the sheet metal and rubber blocks are installed in a specific order, if a rubber block is installed and fixed onto a sheet metal piece first, the surrounding sheet metal pieces that are not yet installed will interfere with the already installed rubber block when the next piece is installed, making it impossible to install the sheet metal. Currently, commonly used expansion rubber blocks are made using a two-color injection molding process and do not have a rotation function. When the expansion rubber block interferes with the sheet metal, the interfered part cannot be installed smoothly. If the sheet metal is forcibly installed, the expansion rubber block will be deformed by the sheet metal, losing its sound insulation and noise reduction function. Summary of the Invention

[0003] The purpose of this invention is to provide a rotatable expansion block structure, which solves the problem of interference between the body panel and the expansion block during installation of the expansion block in the existing technology.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: The rotatable expansion block structure has a fixed block 2 that is rotatably connected to the rotating block 1 by a mounting pin 4. The mounting pin 4 and the fixed block 2 are tightly fitted and held in the installation position by friction, so that the rotating block 1 is fixed at an inclined angle. The rotating block 1 rotates around the central axis of the mounting pin 4 and is positioned by a limit block 3, so that the rotating block 1 moves from position A to position B and remains horizontal with the fixed block 2.

[0005] The left side of the fixing block 2 is provided with two circular connectors 12. The center of the connector 12 is a hollow circular hole 13 for the installation nail 4 to be inserted. After the installation nail 4 is inserted, it is completely sunk into the hole without any protrusion.

[0006] The rotating rubber block 1 has a circular connector 10 on its right side, which is placed between two connectors 12. The center of the connector 10 is a hollow circular hole 11 for the installation nail 4 to be inserted. The circular hole 11, the outer contour of the connector 10 and the installation nail 4 are concentric circles. A limiting block 3 is provided on the outer side of the connector 10. When the rotating rubber block 1 rotates to the horizontal position, it is limited by the limiting block 3, and the installation is completed at this time.

[0007] The advantages of this invention are: the product has a simple mold structure, is easy to assemble, and the expandable rubber block, which can be partially rotated, is convenient to use and solves the problem of interference between the expandable rubber block and the mounting sheet metal. It is highly practical. Attached Figure Description

The fixed expansion block 2 is connected to the rotating expansion block 1 by the mounting pin 4 to form an integral expansion block. The mounting pin 4 and the fixed expansion block 2 are tightly fitted and held in the installation position by friction, so that the rotating expansion block 1 is fixed at an inclined angle. After being subjected to external force, the rotating expansion block 1 can rotate around the central axis of the mounting pin 4 by a certain angle. After rotation, it is positioned by the limiting block 3, so that the rotating expansion block 1 moves from position A to position B and remains horizontal with the fixed expansion block 2.

[0013] The left side of the fixing block 2 is provided with two circular connectors 12. The center of the connector 12 is a hollow circular hole 13 for the installation nail 4 to be inserted. After the installation nail 4 is inserted, it is completely sunk into the hole without any protrusion.

[0014] The rotating rubber block 1 has a circular connector 10 on its right side, which is placed between two connectors 12. The center of the connector 10 is a hollow circular hole 11 for the insertion of the mounting pin 4. The circular hole 11, the outer contour of the connector 10, and the mounting pin 4 are concentric circles. A limiting block 3 is provided on the outer side of the connector 10. When the rotating rubber block 1 rotates to a horizontal position, it is limited by the limiting block 3, and the installation is completed at this time.

Sheet metal 3 7 and sheet metal 4 8 are welded together by weld point 9, and rotating rubber block 1 is at position A at this time; 4. Sheet metal parts 3 7 and 4 8 are joined along the Z direction and then welded and fixed to sheet metal parts 2 6. Rotating rubber block 1 is at position A at this time. V. This will not affect the installation of sheet metal parts 3.7 and 4.8 at this time; 6. The worker uses tools to press the rotating rubber block 1 from position A to position B. The rotating rubber block 1 is now in position B, and the installation is complete.
