Abstract
This utility model provides a chip gasket block suitable for heavy-duty truck oil coolers, relating to the field of cooler core sealing technology. It includes a skeleton ring body with extension plates on both sides. Positioning holes are provided on the extension plates. Inner liner rings are provided on the upper and lower sides of the skeleton ring body. A sealing ring gasket is fitted onto the outer wall of the inner liner ring. Symmetrically arranged clamping half-rings are pivotally connected to the extension plates. A guide ring is fixed to the end of each clamping half-ring facing the positioning hole. The guide ring is concentric with the positioning hole, and its upper surface is a sliding conical surface. An open spring is connected to the end of each clamping half-ring away from the pivot axis. In this utility model, the guide rings are gradually aligned by screw contact, causing the two clamping half-rings to engage and deform the sealing ring gasket, thus forming a seal.
