Description

Technical Field

[0001] The utility model relates to the technical field of thermal resistors, and more specifically to a vibration-resistant thermal resistor. Background Art

[0002] Thermal resistors are the most commonly used temperature detectors in the medium and low temperature range. Thermal resistors are mostly made of pure metal materials, with platinum and copper being the most commonly used. There are many types of temperature sensing materials commonly used for metal thermal resistors, with platinum wire being the most commonly used. In addition to platinum wire, other metal thermal resistor materials used for industrial measurement include copper, nickel, iron, etc. The main features of thermal resistor temperature measurement are high measurement accuracy and stable performance. Among them, platinum thermal resistors have the highest measurement accuracy. They are not only widely used in industrial temperature measurement, but also made into standard reference instruments. Thermal resistor temperature measurement is based on the characteristic that the resistance value of a metal conductor increases with the increase of temperature to measure temperature.

[0003] However, after the thermal resistor in the prior art is installed on the air compressor, the air compressor will generate severe vibration when it is in operation. Excessive vibration may cause the thermal resistor to loosen, resulting in a decrease in measurement accuracy or even failure. In view of this, we propose an anti-vibration thermal resistor.

[0008] A movable seat is fixedly mounted on one end of a plurality of the reset mechanisms facing the monitoring assembly, and a plurality of rubber anti-skid diagonal lines are constructed in a circular array on one side of the movable seat.

[0009] The utility model screws a threaded ring arranged at one end of a thermal resistor body into the device, so that a movable seat provided with a plurality of rubber anti-skid diagonal lines abuts against one side of the device, and squeezes a plurality of reset mechanisms, so that the movable seat is pushed to abut against one side of the device through the plurality of reset mechanisms, so that during the operation of the device, vibration is absorbed through the plurality of reset mechanisms, thereby avoiding the occurrence of loose connection due to vibration, and preventing the occurrence of a decrease in measurement accuracy or even malfunction.

[0010] Preferably, the reset mechanism comprises a guide rod, the guide rod is slidably disposed in the through hole, and one end of the guide rod is fixedly connected to the movable seat.

[0011] Preferably, a limiting ring is fixedly mounted on one end of the guide rod away from the movable seat, and the limiting ring abuts against one side of the fixed seat.

[0012] Preferably, a spring is sleeved on the guide rod, and a plurality of annular cavities are formed in an annular array on one side of the fixed seat facing the movable seat, and two ends of the spring are respectively in contact with the movable seat and one side of the annular cavity.

[0013] Preferably, the monitoring assembly comprises a socket, and a probe is configured on a side of the socket away from the threaded ring.

[0014] Preferably, a plug-in cavity is centrally provided on one side of the threaded ring away from the thermal resistor body, and the plug socket is plugged into the plug-in cavity.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model screws a threaded ring provided at one end of the thermal resistor body into the device, so that a movable seat provided with a plurality of rubber anti-skid diagonal lines abuts against one side of the device, and squeezes a plurality of reset mechanisms, so that the movable seat is pushed to abut against one side of the device through the plurality of reset mechanisms, so that during the operation of the device, vibration is absorbed through the plurality of reset mechanisms, thereby avoiding the occurrence of loose connection due to vibration, and preventing the occurrence of a decrease in measurement accuracy or even failure.

[0017] 2. The utility model also abuts against one side of the device through the movable seat. Since one side of the movable seat is provided with a plurality of rubber anti-skid diagonal lines, after abutting against one side of the device, the plurality of rubber anti-skid diagonal lines abut against the one side of the device and deform, thereby increasing the friction after contact, and pushing the movable seat provided with the plurality of rubber anti-skid diagonal lines to further abut against the device through a plurality of springs, achieving a pressure-maintaining effect, further avoiding the occurrence of loose connection due to vibration.
