Based on above scheme, the material of the installation outer tube of this scheme is brass or stainless steel. Above-mentioned scheme adopts the installation outer tube to avoid temperature probe to receive external disturbance and installation spring to guarantee that temperature probe inserts the installation and targets in place, wherein the installation outer tube provides the passageway of extension for temperature probe's installation, better shielding external disturbance's effect has been played, the one end and the temperature probe of installation spring are connected, the other end is fixed on the rear end of installation outer tube after temperature probe and the effective heat conduction contact of temperature measurement point, continuously exert an elastic pressure for temperature probe, guarantee the stability of heat conduction contact, temperature probe job stabilization nature has effectively been improved, the accuracy of temperature measurement has been improved.
In order to realize that one end of the installation outer sleeve extends into the temperature measuring hole of the object to be measured to form fixed connection, as shown in fig. 1-3, one end of the installation outer sleeve of the scheme is provided with an installation external thread, the installation external thread and the installation internal thread in the temperature measuring hole of the object to be measured form thread fixed connection, and one end of the installation outer sleeve forms fixed connection with the temperature measuring hole of the object to be measured through the thread fixed connection. Based on the above scheme, in order to realize the positioning of the other end of the mounting spring, the present scheme discloses the following examples.
Example one
As shown in fig. 1 and 2, the other end of the installation outer sleeve of the scheme is provided with an internal thread pin hole, an external thread positioning pin is arranged in the internal thread pin hole, and the external thread positioning pin positions the other end of the installation spring. The external thread positioning pin is screwed into the internal thread pin hole until the pin head of the external thread positioning pin clamps the other end of the mounting spring, so that the other end of the mounting spring is positioned.
Example two
As shown in fig. 3, in order to overcome the problem that the installation outer sleeve of the first embodiment is not convenient to be locked by a wrench, a nut structure is arranged at the other end of the installation outer sleeve, and one end of the installation outer sleeve is screwed into the temperature measuring hole of the object to be measured by twisting the nut structure.
