Description
Technical field
The utility model relates to automation instrumentations, and in particular to a kind of oil-filled bimetallic thermometer of inner guide type.
Background technique
Bimetallic thermometer is a kind of on-site test instrument for measuring medium and low temperature.Various production processes can directly be measured
In -80 DEG C -+500 DEG C within the scope of liquid vapour and gas medium temperature.The industrial main element of bimetallic thermometer is one
It is a to be forced together the multilayered metal film of composition with two or more metal film stacks, it is swollen when temperature changes using two kinds of different metals
The different principle of swollen degree.It is based on the forniciform bimetal leaf composition of coiling cyclization.When the expanded by heating of one end, pointer is driven
Rotation, work instrument just show thermoelectrical potential temperature value.
Silicone oil, is filled in bimetallic thermometer by existing filling type bimetallic thermometer aperture on watchcase from hole,
But this way is often that the gauge outfit of bimetallic thermometer is partially filled with silicone oil, and really need antidetonation protection is in protection pipe
Bimetal leaf, the shortcomings that such structure is：Anti seismic efficiency is poor, is easy oil leak, and wants aperture encryption blocking not beautiful on watchcase
It sees.
Utility model content
To solve the above problems, providing a kind of oil-filled bimetallic thermometer of inner guide type, make the inner cavity of entire product full of silicon
Oil, anti seismic efficiency are good.
The purpose of this utility model is realized in the following manner：
A kind of oil-filled bimetallic thermometer of inner guide type, including watchcase 1, protection pipe 4, dial plate 2, pointer 3, needle pivot 5 and set
Temperature-sensing element 6 in protection pipe 4, watchcase 1 are connect with protection pipe 4, and the inside of watchcase 1 is equipped with accommodating chamber, dial plate 2 and pointer 3
It is respectively positioned in accommodating chamber, dial plate 2 is located at the lower section of pointer 3, and pointer 3 is mounted on one end of needle pivot 5, and needle pivot 5 passes through setting
It is fixedly connected after dial plate 2 below pointer 3 with one end of temperature-sensing element 6, the other end of temperature-sensing element 6 is fixed on protection pipe 4
The junction of tail portion, the protection pipe 4 and watchcase 1 is equipped with the bearing 7 cooperated with needle pivot 5, and the bearing 7 is equipped with connection
The oil-through-hole 8 of protection pipe 4 and watchcase accommodating chamber, the tail portion of the protection pipe 4 set protection pipe support 11,11 center of supporting member
If oil filler point 9, oil filler point 9 is sealed by screw plug 10.
The oil-through-hole 8 is two inclined holes for being located at 5 two sides of needle pivot.
The beneficial effects of the utility model：The utility model can make the inner cavity of entire bimetallic thermometer be full of silicone oil,
Anti seismic efficiency is good, and sealing structure effect is good, good appearance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is watchcase；2 be dial plate；3 be pointer, and 4 be protection pipe；5 be needle pivot；6 be temperature-sensing element；7 be axis
It holds, 8 be oil-through-hole；9 be oil filler point；10 be screw plug, and 11 be supporting member.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of oil-filled bimetallic thermometer of inner guide type, including watchcase 1, protection pipe 4, dial plate 2, pointer 3, refer to
Needle shaft 5 and the temperature-sensing element 6 being located in protection pipe 4, watchcase 1 are connect with protection pipe 4, and the inside of watchcase 1 is equipped with accommodating chamber, dial plate
2 and pointer 3 be respectively positioned in accommodating chamber, dial plate 2 is located at the lower section of pointer 3, and pointer 3 is mounted on one end of needle pivot 5, needle pivot 5
It is fixedly connected after the dial plate 2 being arranged in below pointer 3 with one end of temperature-sensing element 6, the other end of temperature-sensing element 6 is fixed on
The junction of 4 tail portion of protection pipe, the protection pipe 4 and watchcase 1 is equipped with the bearing 7 cooperated with needle pivot 5, on the bearing 7
Oil-through-hole 8 equipped with connective protection pipe 4 Yu watchcase accommodating chamber, the tail portion of the protection pipe 4 set protection pipe support 11, the bearing
11 center of part sets oil filler point 9, and oil filler point 9 is sealed by screw plug 10.
The oil-through-hole 8 is two inclined holes for being located at 5 two sides of needle pivot.
Watchcase can be connected to by the utility model by the inclined hole, that is, oil-through-hole on bearing both sides with protection pipe, and pass through protection
Silicone oil is filled in bimetallic thermometer by the oil filler point at the support holes center below pipe, fills the inner cavity of entire bimetallic thermometer
Full silicone oil, anti seismic efficiency is good, and sealing structure effect is good, good appearance.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
