After installation, it can not be rotated again, and the flow direction of medium to be measured is also all fixed unidirectional so that thermocouple is always single
Face is by momentum effect, so as to which thermocouple be caused to be susceptible to bending or the problem of single side is perforated, lead to its reduced service life.
Invention content
Based on above-mentioned background technology, the present invention proposes a kind of thermoelectricity of rotary anti-single side perforation
It is even.
The present invention proposes a kind of thermocouple of rotary anti-single side perforation, including：It terminal box and connect with terminal box
Temperature detector, the junction box are equipped with binding post, and the temperature detector includes thermode and is sleeved on thermode periphery successively
Insulating sleeve, protection tube, wherein：
The side of terminal box be additionally provided with it is outwardly extending and with its integrally formed docking section, docking section is internally provided with by remote
One end from terminal box is to the linearly extended butt hole in one end close to terminal box, and the bottom of butt hole is equipped with and junction box
The duct of connection；
Protection tube is rotatablely connected with insulating sleeve, and one end of protection tube stretches in butt hole and turns with docking section
Dynamic connection, thermode stretch into junction box across duct and are contacted with binding post；Protection tube is close to the outer of terminal box side
Wall is equipped with the push handle being secured to.
Preferably, binding post is located along the same line with duct, and binding post be equipped with from close to the one end in duct to remote
From the linearly extended line chamber in the one end in duct, and when one end of protection tube is stretched in butt hole and is rotatablely connected with docking section
When, one end of the thermode is stretched into line chamber across duct and is bonded with line chamber inner wall.
Preferably, rotary seal between protection tube and butt hole.
In the present invention, by setting docking section in terminal box, butt hole is set inside docking section, at the bottom of butt hole
Portion sets duct, and push handle is set in the outer wall of protection tube, and one end of protection tube is made to stretch in butt hole and and docking section
Rotation connection, and make under protection tube and docking section connection status, thermode stretches into junction box and and wiring across duct
Binding post connection inside box, during thermometric, staff can timing promotion push handle to rotate protection tube, with switching
Its stress surface, to avoid protection tube due to long-term single side by erosion occur being bent or single side perforate the problem of, so as to have
Effect extends the service life of thermocouple.
Description of the drawings
Fig. 1 is a kind of structure diagram of the thermocouple of rotary anti-single side perforation proposed by the present invention.
Specific embodiment
In the following, technical scheme of the present invention is described in detail by specific embodiment.
As shown in FIG. 1, FIG. 1 is a kind of structure diagrams of the thermocouple of rotary anti-single side perforation proposed by the present invention.
With reference to Fig. 1, a kind of thermocouple of rotary anti-single side perforation of proposition of the embodiment of the present invention, including：1 He of terminal box
The temperature detector 2 being connect with terminal box 1, the terminal box 1 are internally provided with binding post 3, the temperature detector 2 include thermode 21 and according to
The secondary insulating sleeve 22 for being sleeved on 21 periphery of thermode, protection tube 23, wherein：
The side of terminal box 1 be additionally provided with it is outwardly extending and with its integrally formed docking section 11, set inside docking section 11
Have and be equipped with from one end far from terminal box 1 to the linearly extended butt hole in one end close to terminal box 1, the bottom of butt hole with connecing
The duct that 1 inside of wire box connects.Protection tube 23 is rotatablely connected with insulating sleeve 22, and one end of protection tube 23 stretches to pair
It connects in hole and is rotatablely connected, and rotary seal between protection tube 23 and butt hole with docking section 11, thermode 21 passes through duct
It stretches into 1 inside of terminal box and is contacted with binding post 3；Outer wall of the protection tube 23 close to 1 side of terminal box is equipped with what is be secured to
Push handle 24.
The present invention works in this way：By setting docking section 11 in terminal box 1, docking is set inside docking section 11
Hole sets duct in the bottom of butt hole, sets push handle 24 in the outer wall of protection tube 23, stretches into one end of protection tube 23
It is rotatablely connected, and makes under protection tube 23 and 11 connection status of docking section in butt hole and with docking section 11, thermode 21 is worn
