Description

Technical Field

[0001] This utility model relates to the field of vacuum filling of antifreeze in expansion tanks of heavy-duty trucks, and particularly to an adapter device for vacuum filling of antifreeze in expansion tanks of heavy-duty trucks. Background Technology

[0002] When filling antifreeze into the expansion tank of heavy-duty trucks, vacuum filling is often used. However, the antifreeze vacuum filling nozzle of most domestically used four-in-one vacuum filling machines does not match well with the expansion tank of heavy-duty trucks, making it impossible to achieve vacuum filling. This results in low online filling efficiency and frequent secondary replenishment of antifreeze during the commissioning process. There is an urgent need for an intermediate matching and docking device. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an adapter device for vacuum filling of antifreeze in the expansion tank of heavy-duty trucks.

[0004] This utility model is achieved using the following technical solution:

[0005] An adapter device for vacuum filling antifreeze into the expansion tank of heavy-duty trucks includes an adapter body, one end of which is a filling machine connector and the other end is an expansion tank connector; a filling channel is provided on the axis of the adapter body, passing through the filling machine connector and the expansion tank connector.

[0006] Furthermore, a rotating clamping protrusion is provided on the outer side of the dispensing machine connector end, and a dispensing gun head hole is provided inside the dispensing machine connector end, the dispensing gun head hole communicating with the dispensing channel.

[0007] Furthermore, an expansion tank connector hole is provided on the expansion tank connector end, the expansion tank connector hole is provided with an internal thread, and a sealing ring communicating with the filling channel is provided at the bottom of the internal thread.

[0008] Compared with the prior art, the present invention has the following beneficial technical effects:

[0009] This utility model serves as an intermediate matching and docking device between the filling gun of the injection machine and the expansion box interface of the heavy truck. It has low manufacturing cost, is easy for operators to use, and requires less work intensity. It is suitable for the assembly line operation of heavy trucks. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise explicitly specified and limited, the embodiments and features described in the embodiments of this application can be combined with each other. In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-2 As shown, an adapter device for vacuum filling antifreeze in the expansion tank of a heavy truck includes an adapter body, one end of which is a filling machine connector end 2, and the other end is an expansion tank connector end 5; a filling channel 4 is provided on the axis of the adapter body, passing through the filling machine connector end 2 and the expansion tank connector end 5.

[0017] A rotating clamping protrusion 1 is provided on the outer side of the dispensing machine connector end 2, and a dispensing gun head hole 3 is provided inside the dispensing machine connector end 2, which communicates with the dispensing channel 4. The diameter of the dispensing gun head hole 3 is larger than the diameter of the dispensing channel 4. In use, the dispensing gun of the dispensing machine is connected to the dispensing machine connector end 2, and tightened by rotating the clamping protrusion 1.

[0018] An expansion tank connector hole is provided on the expansion tank connector end 5, and an internal thread 7 is provided on the expansion tank connector hole. A sealing ring 6, which communicates with the filling channel 4, is provided at the bottom of the internal thread 7. The diameter of the expansion tank connector hole is larger than the diameter of the filling channel 4, and the diameter of the sealing ring 6 is larger than the diameter of the expansion tank connector hole. Before use, check whether the sealing ring 6 is intact and whether the adapter is clean. During use, install the expansion tank connector end 5 onto the expansion tank interface of the heavy truck and tighten it.
