Description

Technical Field

[0001] The utility model relates to the technical field of metrological verification instruments, in particular to an adjustable spacing support net for a thermostatic bath verification frame and a thermostatic bath verification frame. Background Art

[0002] As a common calibration equipment for temperature measurement components, the thermostatic bath is generally used in conjunction with a calibration bracket during the calibration process to improve laboratory work efficiency and facilitate calibration and testing operations. Common thermocouple bracket devices are generally assembled from support rods and support nets, and several thermocouples are fixed to the bracket or support net surface using tools such as wires and clips. Since the calibration holes in the temperature cavity of the thermostatic bath are distributed in a ring shape and the diameters of the calibration holes are different, there will be mutual influence when fixing more thermocouples.

[0003] For example, the utility model patent with patent publication number CN219495516U discloses a "liftable multifunctional calibration frame suitable for PR600 series constant temperature baths". This device uses a lifting support net or support ring to fix the thermometer to be tested, thereby improving the calibration efficiency and providing stability, convenience and safety. By lifting the bamboo dragonfly clips that are not resistant to high temperatures and placing them on the calibration support net, the temperature is greatly reduced, eliminating high temperature safety hazards and improving calibration efficiency.

[0004] However, the supporting effect of the support net is still not ideal in actual use. When calibrating a large number of thermocouples, the support net surface with non-adjustable spacing and the calibration holes in the temperature cavity below cannot correspond well one to one, resulting in tilting and unstable fixation during thermocouple calibration. Therefore, it is urgent to design a support net device with more convenient use and adjustable spacing. Utility Model Content
