Problems solved by technology
However, since thermistor sensors are usually packaged in glass, such thermal sensors are easily damaged by impact
In the absence of a self-locking protection device, the thermal sensor moving up and down is very likely to collide with the sample rack moving forward and backward, so that the thermal sensor is damaged due to the collision, which greatly limits its service life, thereby limiting The use of corresponding instruments

Embodiment Construction
[0020] The structure and working process of the thermistor sensor self-locking protection device of the present invention will be described below with reference to the drawings and embodiments.
[0021] Such as figure 1 , 2 As shown, the thermistor sensor self-locking protection device of the present invention comprises a sample rack 3, a thermosensitive sensor bracket 6, a self-locking mechanism 4 and a control system; the sample rack 3 is fixed on the motor bracket A8 by a guide rail slider A5 At the same time, the motor bracket A8 is fixed on the bottom plate 1, and the sample rack motor 9 fixed on the motor bracket A8 controls the forward and backward movement of the sample rack 3.
[0022] Described thermal sensor support 6 is fixed on the motor support B11 by guide rail slider B7, and simultaneously motor support B11 is fixed on the column 2, and column 2 is fixed on the base plate, and the thermal sensor motor 10 that is fixed on the motor support B11 controls heat Th...

The invention provides a self-lock protector for a thermistor sensor, which comprises a sample frame, a heat-sensitive sensor support, a self-lock mechanism and a control system; and the sample frame is fixed on an electrical machine support A by a guide way slide block A, the electrical machine support A is fixed on a base plate, and an electrical machine of the sample frame fixed on the electrical machine support A controls the sample frame to move forwards and backwards. The self-lock protector has the beneficial effects that a mechanical structure acts due to the motion of a program control electrical machine, so that the self-lock protector is started, and the aim of protecting the thermistor sensor is achieved. The thermistor sensor is fixed on a rack by the support and can move vertically by the means that a wheel / rack drive mechanism is driven by the electrical machine. Therefore, a thermistor sensor pole which moves vertically cannot be collided with the sample frame which moves forwards and backwards. Due to the self-lock protector, an apparatus and the thermistor sensor can be protected, and the service life of the apparatus and the thermistor sensor can be prolonged.
Description
technical field [0001] The invention relates to a self-locking device for a heat-sensitive sensor, in particular to a self-locking protection device for a heat-sensitive sensor, which is used to protect the heat-sensitive sensor so as to prevent the heat-sensitive sensor from being damaged due to collision. Background technique [0002] For a long time, thermal sensors have played a very important role in temperature measurement, temperature control, temperature compensation and temperature recording. It has been widely used in instruments and meters, especially for instruments closely related to temperature detection, such as osmolarity instrument. However, since the thermistor sensor is usually packaged in glass, the thermistor sensor is easily damaged after being bumped. In the absence of a self-locking protection device, the thermal sensor moving up and down can easily collide with the sample rack moving forward and backward, so that the thermal sensor is damaged due to...
