Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a sudden jump type temperature controller. Background Art

[0002] As we all know, the Jumping Temperature Controller is a special type of thermostat, also known as a stepping thermostat.

Jumping thermostats are widely used in fields that require precise temperature control, such as laboratory instruments, medical equipment, industrial heating or cooling systems, etc. It can provide higher temperature control accuracy and stability to meet the requirements of specific applications.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN220585137U discloses a thermostat, which includes a thermostat body; a fixing member, which is arranged on the thermostat body; a wiring mechanism, which is arranged on the thermostat body; the wiring mechanism includes: a wiring screw core, a support nut and a locking nut, the wiring screw core is fixedly connected to the thermostat body; the support nut is connected to the wiring screw core; the locking nut is connected to the outer side of the wiring screw core relative to the support nut. Although the existing jump-type thermostat uses bolts to lock the thermostat body, due to the influence of external factors such as vibration, long-term use will still cause the bolts to vibrate and become unthreaded, thereby making the installation stability of the thermostat weak.

[0004] Therefore, the prior art for the above problems still needs to be improved and developed. Utility Model Content

Through the above structure, when actually used, the movable part is pushed so that the movable part slides along the guide rod toward the fixed part, and the movable part squeezes the second spring at the same time, and then the cable reel is looped and sleeved on the outside of the movable part and the fixed part, and the movable part is released so that the second spring recovers its deformation, so that the movable part is always in contact with the cable, so as to ensure the tensioning effect of the movable part and the fixed part, and the cable can be stored and processed to avoid the problem of scattered cables.

[0011] According to the above scheme, the mounting plate is provided with a receiving groove, the guide rod is fixed in the receiving groove, the lower end of the fixing member is fixed on the guide rod, and the lower end of the fixing member is limited in the receiving groove, the lower end of the moving member is slidably inserted on the guide rod, and the lower end of the moving member is limited in the receiving groove, and the cable is wound around the outer side of the upper part of the fixing member and the moving member.
