Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0013] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0014] like Figure 1-2As shown, the high-strength riveted temperature sensor includes a metal bottom shell 1, a plastic part 2 and a thermistor 3. The lower end of the plastic part 2 is sequentially provided with a rivet groove 4 and a rivet section 5. The metal bottom shell 1 is sequentially provided with a rivet portion 6, a nut portion 7, a plug-in portion 8 and a sensing portion 9. The interior of the rivet portion 6 is provided with an annular support platform 10. The outer side of the nut portion 7 is provided with a hexagonal nut 11 integrally formed with the nut portion 7. The rivet section 5 is inserted into the rivet portion 6 and placed on the annular support platform 10.
