Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a water temperature sensor.

In this embodiment, referring to fig. 1 to 5, this water temperature sensor includes measuring rod 1 and connecting plug 2, be equipped with mounting groove 3 that runs through the connecting plug 2 lateral wall on the lateral wall of connecting plug 2, the both sides of mounting groove 3 are equipped with spacing groove 4, be equipped with hold-down mechanism 5 in the mounting groove 3, hold-down mechanism 5 include compressing blade 6 and return elastic component 7, the both sides of compressing blade 6 extend there is spacing step 8, and compressing blade 6 can reciprocate in the mounting groove through spacing step 8 and the restriction of spacing groove 4, return elastic component one end links to each other with spacing step, and the other end links to each other with spacing groove upper wall in the mounting groove.
