Detailed Description
The invention is further illustrated by the following examples.
Referring to fig. 1 to 4, a double-sheet type manual reset snap-action thermostat comprises a sealing cover 1, a1 st bimetallic disk 2, a1 st action rod 3, a guide frame 4, a shell 6, a terminal 7, a rivet 8, a moving contact support 9, a cover plate 10, a fixed contact connecting plate 14, a fixed contact 15, a moving contact 16, a reset rod 18 and a reset handle 19, wherein the 1 st bimetallic disk 2 is placed on the guide frame 4, one side of the terminal 7 is connected with the moving contact support 9 and the shell 6 through the rivet 8 in a riveting way, the center of the cover plate 10 is provided with a manual reset mechanism consisting of the reset rod 18 and the reset handle 19, a bracket 5 is arranged between the guide frame 4 and the shell 6, a 2 nd bimetallic disk 12 is arranged in a space between the guide frame 4 and the bracket 5, the periphery of the 2 nd bimetallic disk 12 is in contact connection with the bracket 5, a 2 nd action rod 11, a transmission rod 3 and a push rod 17 are arranged between the shell 6 and the 1 st action rod 3, the 1 st action rod 3 penetrates through a middle through hole of the 2 nd action rod 11 to be in contact connection with the upper end face of the push rod 17, the upper end face of the 1 st action rod 3 is in movable contact connection with the 1 st bimetallic disk 2, the push rod 17 is in movable sleeve connection with the transmission rod 3, a circular groove is arranged in the middle of the upper top of the transmission rod 13 and is in matched contact connection with a cylindrical head at the upper top of the push rod 17, the 2 nd action rod 11 is in movable contact connection with the end face of the transmission rod 3, the lower end face of the transmission rod 13 is in contact connection with the moving contact support 9, and the lower end face of the push rod 17 is in movable contact connection with the upper end face of the reset rod 18.
The reset temperature of the 1 st bimetal disc 2 is minus 35 ℃ or lower. The reset rod 18 and the reset handle 19 are pressed together to form a manual reset mechanism, and the manual reset mechanism moves up and down between the cover plate 10 and the ejector rod 17.
The working process of the double-sheet type manual reset kick temperature controller is as follows:
Referring to fig. 3, when the reset lever 19 is pressed upwards, the push rod 17 and the 1 st action lever 3 are pushed to move upwards, so that the 1 st bimetal disc 2 cannot act when sensing temperature, and the 2 nd bimetal disc 12 can normally act when sensing temperature, so that the 2 nd action lever 11 is driven to push the transmission rod 13 to move downwards, thereby pushing the moving contact bracket 9 downwards, and separating the moving contact 16 from the fixed contact 15, and at the moment, the normal action of the temperature controller is not influenced by pressing the reset mechanism upwards.
Referring to fig. 2, when the 1 st bimetal disc 2 senses a temperature action (overturns downwards), the 1 st action rod 3 is driven to push the ejector rod 17 and the transmission rod 13 downwards, so that the moving contact bracket 9 is pushed downwards, and the moving contact 16 is separated from the fixed contact 15; meanwhile, the 2 nd bimetal disc 12 also senses temperature and acts simultaneously (overturns downwards), so that the 2 nd actuating rod 11 is driven to push the transmission rod 13 downwards, thereby pushing the moving contact bracket 9 downwards, and separating the moving contact 16 from the fixed contact 15. When the ambient temperature is lower than the operating temperature of the temperature controller (for example, the range of 40-140 ℃) and higher than the normal operating temperature (for example, the range of 0-100 ℃), if an upward external force is applied to the reset handle 19 at this time, the reset lever 18 acts on the push rod 17 and the 1 st operating lever 3 to reset (upward) the 1 st bimetallic disk 2, and the 2 nd bimetallic disk 12 does not reach the reset temperature rebound (still is downward) due to the fact that the ambient temperature is higher than the normal operating temperature, the movable contact 16 and the fixed contact 15 still remain in a separated state, as shown in fig. 3. As the ambient temperature continues to decrease, when the 2 nd bimetal disc 12 is cooled to the normal operation temperature, the reset temperature jumps back (upward) to bring the moving contact 16 into contact with the fixed contact 15 again, as shown in fig. 1, so that not only the "M1-automatic trip" function can be realized, but also the requirement of the customer on the normal operation temperature range can be met by adjusting the reset temperature of the 2 nd bimetal disc 12.
When the 1 st bimetal disc 2 senses temperature action (overturns downwards), the 1 st action rod 3 is driven to push the ejector rod 17 and the transmission rod 13 downwards, so that the movable contact support 9 is pushed away, and the movable contact 16 is separated from the fixed contact 15; meanwhile, the 2 nd bimetal disc 12 also senses temperature and acts simultaneously (overturns downwards), so that the 2 nd actuating rod 11 is driven to push the transmission rod 13 downwards, thereby pushing the movable contact support 9 away, and separating the movable contact 16 from the fixed contact 15, as shown in fig. 2. When the manual reset mechanism is in the initial position, the 2 nd bimetal disc 12 jumps back when the ambient temperature is reduced to the normal operation temperature, but the moving contact 16 and the fixed contact 15 still keep the separated state as the 1 st bimetal disc 2 does not jump back when the ambient temperature is reduced to the reset temperature, as shown in fig. 4. Only when the ambient temperature drops below-35 c, the 1 st bimetal disc 2 reaches its reset temperature and jumps back, at which point the moving contact 16 and the fixed contact 15 come into contact again, as shown in fig. 1.
