Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 and 2, a melt thermometer with a protection device comprises a fixed seat 1, a protection sleeve 2 and a metal ceramic thermocouple 9, wherein the protection sleeve 2 is welded on one side of the fixed seat 1, a sleeve 4 for protection is sleeved on the periphery of the protection sleeve 2, one end of the sleeve 4 is connected with a supporting seat 3 through a bolt, the protection sleeve 2 penetrates through the supporting seat 3, a push rod 5 is welded on the periphery of the protection sleeve 2 on one side of the fixed seat 1, and the push rod 5 penetrates through the supporting seat 3.

Wherein, the periphery of sleeve 4 one end is fixed and is provided with cooling tank 12, be provided with miniature fan 13 in the cooling tank 12.

In this embodiment, as shown in fig. 4, after the cermet thermocouple 9 is used, the cooling tank 12 and the micro fan 13 can perform auxiliary blowing heat dissipation cooling treatment on the cermet thermocouple, so that the use is safer and more reliable.

The periphery of the push rod 5 is positioned between the fixed seat 1 and the supporting seat 3, a pressure spring 6 is sleeved on the periphery of the push rod 5, fixing screws 7 are arranged on two sides of the supporting seat 3 through reserved openings, and threaded holes 8 corresponding to the fixing screws 7 are formed in the surface of the push rod 5.

In this embodiment, as shown in fig. 1 and 3, the supporting seat 3 is pushed by the elastic force of the pressure spring 6, so that the reset action can be quickly completed, the periphery of the metal ceramic thermocouple 9 is protected, and the supporting seat 3 and the sleeve 4 can be limited and fixed in the using process through the fixing screw 7 and the threaded hole 8.
