Description
Technical field
The utility model relates to a kind of temperature sensor, especially a kind of antivibration temperature sensor.
Background technique
Existing temperature sensor includes protection pipe, installation set, terminal box, and protection tube cavity lower end is equipped with temperature element,
Temperature element is connect by the conducting wire inside protection pipe with terminal box.The end of protection pipe, which is inserted into equipment, needs temperature collection
The position of signal.The sensor of this structure is logical without antivibration function, protection pipe end and measured piece category hard contact, when vibration
It will appear and leave each other phenomenon, cannot keep certain contact force, the temperature signal of acquisition is not accurate.
Summary of the invention
A kind of the purpose of the utility model is to provide structures simple, protecting tube for temperature sensor end and measured piece can be always
Keep certain contact force, temperature signal collection accurately antivibration temperature sensor.
The antivibration temperature sensor of the utility model, including protection pipe, installation set, terminal box, protection tube cavity lower end are set
There is temperature element, temperature element is connect by the conducting wire inside protection pipe with terminal box；It is equipped in the inner hole of the installation set
Spring, washer, sealing ring, snap ring are fixed with upper cover in the upper end surface of installation set, and washer is located at the upper end of spring, washer with
Sealing ring is equipped between upper cover, snap ring is located between the step on the lower end and installation set inner hole of spring, in the lower end of installation set
Have an external screw thread, the protection pipe be inserted into upper cover, sealing ring, washer, spring, snap ring centre bore in, snap ring and protection pipe
Between be fixedly connected.
The antivibration temperature sensor of the utility model, due to snap ring fixed connection opposite with protection pipe, protection pipe after installation
End is contacted with measured piece, and spring is kept to have a certain amount of compression, and snap ring and protection pipe are relative to installation set after spring-compressed
There is a certain amount of axial movement, in vibration processes, can also remain that protection pipe end is contacted with measured piece, there is structure letter
Single, protecting tube for temperature sensor end and measured piece can remain the accurate advantage of certain contact force, temperature signal collection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Fig. 2 is the section view three-dimensional structure diagram at installation set shown in FIG. 1.
Specific embodiment
It is as shown in Figure 1, 2: the antivibration temperature sensor of the utility model, including protection pipe 8, installation set 3, terminal box 10,
8 inner cavity lower end of protection pipe is equipped with temperature element, and temperature element is connect by the conducting wire inside protection pipe 8 with terminal box 10.Installation
It is equipped with spring 5, washer 4, sealing ring 2, snap ring 6 in the inner hole of set 3, is fixed with upper cover 1, washer 4 in the upper end surface of installation set 3
Sealing ring 2 is equipped between the upper end of spring 5, washer 4 and upper cover 1, snap ring 6 is located at 3 inner hole of lower end and installation set of spring 5
On step between, have an external screw thread 7 in the lower end of installation set 3, protection pipe 8 be inserted into upper cover 1, sealing ring 2, washer 4, spring 5,
In the centre bore of snap ring 6, it is fixedly connected between snap ring 6 and protection pipe 8.
The antivibration temperature sensor of the utility model is protected after installation due to snap ring 6 and the relatively fixed connection of protection pipe 8
8 end of pipe is contacted with measured piece 9, and spring 5 is kept to have a certain amount of compression, and snap ring 6 and protection pipe 8 are opposite after the compression of spring 5
There is a certain amount of axial displacement in installation set 3, in vibration processes, can also remain that 8 end of protection pipe connects with measured piece 9
Touching, with structure, simple, protecting tube for temperature sensor end and measured piece can remain that certain contact force, temperature signal are adopted
Collect accurate advantage.
