Car heater water tank with movable inflow and outflow pipes

Abstract

The invention proposes a vehicle heater water tank with movable inflow and outflow pipes, which includes a core body, a water chamber and inflow and outflow pipes. The sealing jacket is welded on the inlet and outlet of the water chamber, the center of which is a channel through which the top and bottom go, and there is a circle of bosses in the middle of the inner wall, and several notches are evenly opened in the upper part of the circumference. A ring of upset discs is arranged on the outer wall of the connecting end of the inflow and outflow pipes. The O-shaped sealing ring is installed on the boss on the inner wall of the sealing jacket, the inflow and outflow pipes are inserted into the sealing jacket, the O-ring is compressed between the lower surface of the upset plate and the upper plane of the boss, and the notch of the sealing jacket The upper wall is inwardly dented and snaps onto the upper surface of the upset plate. After the connection of the present invention, the inflow and outflow pipes cannot move linearly along the axial direction, but can rotate within a small angle without leakage. In this way, when assembling with the shell, the assembly angle of the pipeline can be adjusted according to the situation, so that it can be aligned with the casing. The shell is tightly fitted, thereby avoiding the failure of the pipeline due to fatigue fracture due to vibration.

Description

technical field [0001] The invention belongs to the vehicle accessory technology, and in particular relates to a vehicle heater water tank. Background technique [0002] see figure 1 , The warm air water tank is a supporting part used with the warm air device on the car, and generally consists of the core body 3, the left and right water chambers 1 and the inflow and outflow pipes 2. The inflow and outflow pipes are respectively connected to the water chambers, and usually the connected joints are fixed, thereby also fixing the positions of the inflow and outflow pipes. In the assembly of the heater water tank and the car body, the inflow and outflow pipelines need to be closely fitted and fixed with the heater shell during the assembly process. Since the shape of the inflow and outflow pipelines is relatively complicated, the connection between the inflow and outflow pipelines and the water chamber of the heater tank It is a rigid connection, and the position after connec...

Problems solved by technology

In the assembly of the heater water tank and the car body, the inflow and outflow pipelines need to be closely fitted and fixed with the heater shell during the assembly process. Since the shape of the inflow and outflow pipelines is relatively complicated, the connection between the inflow and outflow pipelines and the water chamber of the heater tank It is a rigid connection, and the position after connection is relatively fixed. In the actual assembly process, due to processing errors, the pipeline and the shell cannot fit well, and the pipeline is not fixed firmly, which will cause the pipeline to be damaged due to vibration and other reasons.
