The utility model relates to a thermal dual-metal sheet temperature control switch,which is used for controlling the on-off of an engine cooling fan in a motor car,comprising a case,a guide seat,a bimetallic sheet,a tappet and a switch composed of a spring leaf and a binding post.The bimetallic sheet is symmetrical and smaller than a circle such as a triangle and a square.The bimetallic sheet overcomes the defect that the circle metal sheet gets large temperature difference when the circle metal sheet converts up and down.[#89206646#] The utility model relates to an improvement for a gearing device of an X-ray machine remote controller.The utility model is designed for the moving of a fluoroscopic screen and the gearing of a gastrointestinal compressor.A long trip-shaped chain is designed on the framework of the motor ,and the fluoroscopic screen driven by the running of the motor moves oppositely along the chain.The motor drives the cam and pokes two half-concave wheels,causing the two half-concave wheels to bite with each other and change positions with each other ,so that the swinging movement of the gastrointestinal compressor comes true .Provided with an AC speed-reducing and reversible motor,the utility model does not need rectification or speed reducing,and has the advantages of small size,light weight,large force moment,etc.In addition,the gearing device has the advantages of simple structure,reliable and stable movement,no noise and long service life.

Answer 1

The utility model relates to a temperature controlled switch,comprising a thermal dual-metal sheet,an adjusting mechanism and a set of electrical contacts.The utility model is characterized in that the electrical contacts are normally open,and the contacts convert original off-state into on-state when the temperature of the thermal dual-metal which is heated goes up to the designated value.With an acoustic device,an acousto-optical device or a corresponding acting device,the utility model can be used for temperature control alarming,dangerous alarming or security protection and energy-saving operation for the heating device,the cooker which is heated or the water and food in the cooker,under the situation of various thermal sources such as electricity,coal ,firewood,gas,oil,etc.The utility model has the advantages of simple structure ,low cost,convenience use ,and high efficiency .[#89209324#] The utility model relates to a safety power saving lighting lamp for machine tool aperation,comprising a universal ball lamp socket (1),a laminated board(2),a universal ball (5),a flexible snake skin lampholder(6),electric wires (7)and(8),a lamp cap(13),a transformer B-[1],full-bridge rectifiers D-[1]～D-[4],a capacitor C-[1] and a trichromatic fluorescent lamp.Instead of a 60w bulb,a 9w trichromatic fluorescent lamp is arranged on the utility model,saving 80% power.Compared with the existing lighting lamp for machine tool aperation ,the service life of the utility model increases to 7 times ,and the light is softer .With a 10w power transformer,the loss is less .
