[0002] Liquid expansion thermostats, also known as pressure-type temperature switches and capillary temperature protectors, utilize the physical property of liquid thermal expansion and contraction. Through components such as diaphragms, capillaries, and temperature sensing cylinders, the heat exchange medium of the controlled object is heated or cooled and contracts, thereby controlling the contact or separation of the spring contacts inside the liquid expansion thermostat to produce an on / off action, thus achieving the function of temperature control.

[0003] During the factory testing phase of liquid expansion thermostats, testing their temperature control performance is crucial. Traditional testing methods mainly rely on manual operation, and the specific steps include: taking a single liquid expansion thermostat and placing it in a heating furnace; then, raising the temperature to a predetermined value using heating elements in the furnace; finally, observing whether the liquid expansion thermostat can correctly disconnect the circuit when the predetermined temperature is reached to determine whether its performance is qualified.

[0004] However, traditional methods can only test one liquid-expansion temperature controller at a time. In mass production, this inefficient testing method obviously cannot meet production needs, seriously affecting production efficiency and product quality. Utility Model Content

[0009] Both the display device and the probe are electrically connected to an external controller.

[0010] Furthermore, the mounting plate has an arc-shaped structure and a wiring hole in the middle;

[0011] When the mounting plate rotates by a predetermined angle, the wiring hole is opposite to the opening of the heating furnace, and the temperature sensing bag of each liquid expansion temperature controller enters the heating furnace through the wiring hole.

[0012] Further, the two probes are fixedly connected to the mounting plate and are clamped to the bent pin of the liquid expansion temperature controller.

[0013] Further, the clamp comprises a first pressing block and a second pressing block fixedly installed on the mounting plate, and a top block is slidably connected between the first pressing block and the second pressing block, and the first pressing block and / or the second pressing block is provided with a locking piece for locking the top block.

[0014] Further, the top of the mounting plate is provided with a guide block, and the top block and the guide block are slidably connected.

[0015] Further, the clamp comprises a stop seat, the front end of the stop seat is provided with two limiting blocks, the upper side of the mounting plate is provided with two elastic sheets, and a space for placing the liquid expansion temperature controller is formed between the two limiting blocks, the stop seat and the two elastic sheets, and the limiting blocks are connected to the mounting plate by fasteners.

[0016] Further, the two probes are respectively installed on the side edges of the two limiting blocks and extend through the front side of the limiting blocks, and the front ends of the probes abut against the bent pin of the liquid expansion temperature controller.
