Detailed description of the invention
Invention below for the present invention is described further:
nullAs shown in the figure，A kind of thermorelay，Including pedestal 1、Tripping mechanism、Thermal compensation mechanism、Contact Breaking/Making Operations mechanism and stop button 2，Described thermal compensation mechanism matches with tripping mechanism，Described tripping mechanism includes dropout swing arm 3、Spring 4 and push rod 5，Described push rod 5 matches with Contact Breaking/Making Operations mechanism，Described stop button 2 matches with Contact Breaking/Making Operations mechanism，Described pedestal 1 is provided with support 6，Described dropout swing arm 3 can swing along support 6，And described dropout swing arm 3 is connected with push rod 5，Described spring 4 is connected with dropout swing arm 3，Described pedestal 1 is provided with chute 7，Described stop button 2 slides up and down along chute 7，Described stop button 2 is provided with push rod 8，Described push rod 8 is corresponding with dropout swing arm 3，Also between the side of dropout swing arm 3 and stop button 2, there is certain free gap 9 in the top of described chute 7，Described stop button 2 is swung to the right by free gap 9 and constitutes described push rod 8 and push up pressure-off and buckle swing arm 2 and swing along support 6，Described dropout swing arm 2 drives push rod 5 to move and makes the disjunction of Contact Breaking/Making Operations mechanism.Contact Breaking/Making Operations mechanism includes normally closed interlock, and under normal circumstances, normally closed interlock is in closure state, when needing stopping function, presses stop button, thus drives normally closed interlock disjunction, the most normal or purpose of urgent need cut-off loop with realization test product；When performing test function, the most only need to operate stop button 2, stir to the right the operating side of stop button, owing to there is certain free gap between stop button and chute, therefore, stop button swings and drives push rod top to be pressed in dropout swing arm 3, support is Y-shaped structure, under the action of the spring, dropout swing arm 3 along bracket slide, and can be plugged in the socket of push rod during the lower end of swing arm 3 of threading off, therefore, drive push rod is moved to the left, and drives normally closed interlock disjunction by push rod, to realize the purpose of test.According to such scheme, owing to this thermorelay uses, a push rod is set on stop button, replace existing mechanism for testing, stop button is provided simultaneously with stopping function and test function, it is effectively reduced parts, reduces production cost, and the structure of product is simpler, reasonable, the stability of test function is effectively ensured, convenient and simple for operation.
In the present invention, described push rod 8 is connected with stop button 2 one.Both use integrated injection molding, easy to process.
In the present invention, being provided with limiting plate 10 between upper end and the support 6 of described chute 7, formed and penetrate mouth 11 between described limiting plate 10 and pedestal 1 surface, described push rod 8 pushes up press-fit through penetrating mouth 11 with dropout swing arm 3.The upper end of support has with the upper end of chute and communicates structure, communicates contact position arrange a limiting plate at this, and formed between limiting plate 10 and pedestal 1 and penetrate mouth 11, pass for push rod, play spacing purpose, prevent push rod from deviateing shift position, cause the inefficacy of test function.
In the present invention, described tripping mechanism also includes that connecting rod 12, lever 13 and rocking arm 14, described connecting rod 12 match with thermal compensation mechanism, and described lever 13 matches with connecting rod 12, described rocking arm 14 matches with lever 13, and described dropout swing arm 3 is connected with rocking arm 14 by described spring 4.Thermal compensation mechanism includes double gold compensating plate, during its heated bending, drivening rod, and connecting rod drives lever, lever drives rocking arm, and rocking arm drives dropout swing arm that product is threaded off.Dropout good stability, effectiveness is high.
In the present invention, the lower section of described stop button is provided with and extends and elasticity of plastics sheet 15 integrated with pedestal towards horizontal direction, and the described downward sliding of stop button 2 also pushes up pressure described elasticity of plastics sheet 15 flexural deformation.This stop button structure replaces original spring by increasing elastic plastic member at pedestal, thus decreases a part, saves assembly process, and easy to assembly, the used time is less, effectively stops to cause the generation of product failure situation because spring comes off.
In the present invention, the outer end of described elasticity of plastics sheet 15 is bending part 16, and described bending part 16 is serpentine, and described stop button 2 pushes up press-fit with the outer end of bending part 16.The outer end of this flexure strip 4 uses bending part 16, and is the serpentine structure of upwards bending so that when stop button top is pressed in this end, and the elastic deformation effect of generation is more preferable, and reset function is higher.
In the present invention, on described pedestal 1 and be positioned at the lower section of stop button 2 and be provided with vertical direction upwardly extending elasticity of plastics part 17, described elasticity of plastics part 17 is integrally formed by connecting with pedestal 1, and described stop button 2 slide downward also pushes up pressure described elasticity of plastics part 17 compression.This stop button structure, by the optimization to existing structure, increases feature at pedestal, utilizes the elastic deformation of working of plastics to play the effect of original spring.Having an advantage in that and decrease a part, spring assembly process can save, easy to assembly, and the used time is less, fundamentally stops to cause the generation of product failure situation because spring comes off.
Described elasticity of plastics part 17 is sequentially overlapped by multiple annular rings 18 and is formed by connecting.This elasticity of plastics part 17 is formed by connecting by multiple annular rings 18 being sequentially overlapped, the annular ring 18 of compression molding material elastic component 17 is pushed up at stop button 2, annular ring 18 is deformed, by the Superposed Deformation of multiple annular rings 18 so that the elastic performance of overall elasticity of plastics part 17 is more preferable.
Invention is not construed as the restriction invented, but any spiritual improvements introduced based on the present invention, all should be within protection scope of the present invention.
