Referring to fig. 1, a clamp type temperature sensor 10 includes: temperature sensor 100, clamp external member 200 and antiskid external member 300. The temperature sensor 100 is a core component of the clamp type temperature sensor 10, and functions as a temperature sensor. The clip kit 200 is a component for mounting a temperature sensor. The anti-slip kit 300 is a component for improving the installation stability of the temperature sensor.

Referring to fig. 1, 2 and 4, the clamp kit 200 includes a clamp ring 210, a stud 220, a first locking nut 230 and a second locking nut 240, the temperature sensor 100 is mounted on the clamp ring 210, the clamp ring 210 has two clamping arms 211, each of the two clamping arms 211 has a protrusion 212, each of the two protrusions 212 has a through hole (not shown), the stud 220 is located in the two through holes, one end of the stud 220 is exposed out of one of the through holes, the other end of the stud 220 is exposed out of the other through hole, the first locking nut 230 is screwed with one end of the stud 220, and the second locking nut 240 is screwed with the other end of the stud.

It should be noted that, when the temperature sensor 100 needs to be installed, the two clamping arms 211 of the clamp ring 210 are opened, the two clamping arms 211 preliminarily clamp the round object to be installed, the first locking nut 230 is screwed with one end of the stud 220, the second locking nut 240 is screwed with the other end of the stud 220, so that the two convex portions 212 can be close to and attached to each other, the round object to be installed is further stably clamped by the two clamping arms 211, and the installation of the temperature sensor 100 can be completed according to the above operation method. Meanwhile, if the temperature sensor 100 needs to be disassembled at a later stage, the disassembly of the temperature sensor 100 can be realized by reversing the operation process.

Referring to fig. 1, the anti-slip kit 300 includes a first anti-slip pad 310 and a second anti-slip pad 320, wherein the first anti-slip pad 310 is mounted on one of the clamping arms 211, and the second anti-slip pad 320 is mounted on the other clamping arm 211. It should be noted that, in the process of clamping the circular object to be installed by the clamp ring 210, the first anti-slip pad 310 and the second anti-slip pad 320 can both increase the friction force between the clamp arm 211 and the circular object to be installed, so that the temperature sensor 10 can be stably installed on the circular object to be installed, and even if the temperature sensor 100 is subjected to an external force, the problem of position deviation will not occur.

Referring to fig. 2, further, in some embodiments, the first non-slip mat 310 and the second non-slip mat 320 are provided with a plurality of elastic engaging portions 330. It should be noted that, due to the arrangement of the elastic snapping portion 330, in the process of clamping the round object to be mounted by the two clamping arms 211, the elastic snapping portion 330 can further increase the friction force between the two clamping arms 211, and further improve the mounting stability of the temperature sensor. In addition, some convex particles may be added on the surface of the elastic engaging portion 330, so as to further increase the friction force between the elastic engaging portion and the clipping arm 211.

Referring to fig. 3, in some embodiments, the clamp ring 210 is provided with two tension members 212 at a bottom position, wherein one tension member 212 is connected to one of the clamping arms 211, and the other tension member 212 is connected to the other clamping arm 211. It should be noted that, due to the arrangement of the two tension members 212, the tension members 212 can apply inward tension to the clamping arms 211, so as to well ensure the clamping force of the clamp ring 210 on the circular object to be mounted, and prevent the clamp ring 210 from losing the clamping force on the circular object to be mounted due to the long-term opening of the clamp ring 210.

Referring to fig. 2, further, in some embodiments, the temperature sensor 100 includes a housing 110, a thermistor (not shown), a first connecting member 120 and a second connecting member 130, the housing 110 is mounted on the clamp ring 210, the housing 110 is provided with a probe 111, the thermistor is encapsulated in the probe 111 through epoxy resin (not shown), one end of the first connecting member 120 is connected to one end of the thermistor, the other end of the first connecting member 120 is exposed out of the housing 110, one end of the second connecting member 130 is connected to the other end of the thermistor, and the other end of the second connecting member 130 is exposed out of the housing 110.

The housing 110 plays a role of protection and encapsulation. The thermistor plays a role in temperature sensing, when the ambient temperature of the temperature sensor 100 changes, ambient heat is transferred to the thermistor through the casing 110 to cause a change in the resistance value of the thermistor, and the external measuring device reads the current resistance value of the thermistor through the first connecting piece 120 and the second connecting piece 130 to correspondingly convert the current resistance value into an ambient temperature value.

Referring to fig. 2, in some embodiments, the probing tip 111 is provided with a copper powder layer 111a at a sidewall position. The copper powder layer 111a is provided to improve thermal conductivity and allow ambient heat to be more rapidly transferred to the thermistor through the case 110.
