Two thermocouple cores, the lower section of the outside protective case are equipped with two internal protective cover pipes, and every internal protective cover pipe is socketed thermocouple
Core, the outside protective case are equipped with adjustable lifting component；The thermocouple core passes through adjustable lifting component, described adjustable
Formula lifting assembly includes bellows, upper junction plate, lower connecting plate, hairspring, cage plate, and the upper end of the bellows passes through upper connection
Plate connects outside protective case, the lower end of the bellows by lower connecting plate connection outside protective case, it is described above and/or under connect
Plate is equipped with hairspring, and the hairspring is equipped with the cage plate with through-hole, and the thermocouple core passes through through-hole.
Further, pass through flanged joint between the outside protective case and terminal box.
Further, the inside of the outside protective case is equipped with thermal insulation layer.
Further, the inside of the internal protective cover pipe is equipped with anti-corrosion layer.
Further, the anti-corrosion layer is ceramic fiber cotton layer.
Further, the cage plate is rubber cage plate.
Compared with prior art, the invention has the benefit that thermocouple core is effectively protected in inside and outside double shielding casing,
Thermocouple core is not easily susceptible to corrode, long service life, meanwhile, adjustable lifting component is equipped on outside protective case, due to this
Component, as connector, is effectively stretched using bellows, adjusts length as needed, meanwhile, it can also be achieved a degree of
Bending, adjustment direction, realization quickly adjusts thermocouple in use, easy to use, easy to operate；Effectively avoid heat
Influence of the swollen shrinkage to thermocouple.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is structural schematic diagram of the invention.
In figure: terminal box 1, outside protective case 2, internal protective cover pipe 3, thermocouple core 4, adjustable lifting component 5, bellows
51, upper junction plate 52, lower connecting plate 53, hairspring 54, cage plate 55, flange 6, thermal insulation layer 7.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.
As shown in Figure 1 and Figure 2, a kind of adjustable corrosion-resistant from lifting thermocouple including terminal box 1, outside protective case 2, interior
Protection sleeve pipe 3, thermocouple core 4, adjustable lifting component 5, the lower section of terminal box connect outside protective case, are equipped in outer jointing jacket
Two thermocouple cores, the lower section of outside protective case are equipped with two internal protective cover pipes, and every internal protective cover pipe is socketed thermocouple core, outside
Protection sleeve pipe is equipped with adjustable lifting component；Thermocouple core passes through adjustable lifting component, and adjustable lifting component includes wave
The upper end of line pipe 51, upper junction plate 52, lower connecting plate 53, hairspring 54, cage plate 55, bellows connects outer protect by upper junction plate
The lower end of protecting pipe, bellows connects outside protective case by lower connecting plate, is equipped with thin bullet on upper junction plate and lower connecting plate
Spring, hairspring are equipped with the cage plate with through-hole, and thermocouple core passes through through-hole.The setting of hairspring primarily serves certain connection
The effect of support, while spring also acts as absorption displacement, reduces the effect of vibration, in hairspring upper joint sleeve plate, cage plate is main
Good supporting role and guiding function are played to thermocouple core, so that thermocouple core moves in through-hole.The structure of bellows
So that when in use, bellows can be stretched, the length variable length of bellows shortens, and can effectively draw according to actual needs
Bellows is stretched, the thermocouple core in bellows can also be stretched effectively, and certainly, the stretching distance of bellows itself is shorter, contracting
The length for being placed on the thermocouple core in bellows is shorter, therefore, when stretching, can't generate break, heating conduction etc.
Influence, its distance for stretching originally of the present invention is not long, mainly effectively prevent thermocouple when in use itself heat expansion it is cold
Contracting.Cage plate is using insulation cage plate.Meanwhile the structure setting of interior outside protective case of the invention, thermocouple core is played good
Protective action, it is effective corrosion-resistant.Can be filled in bellows resistant material such as ceramic fiber cotton play it is good corrosion-resistant
Effect.
