One or more embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
1-5, a reusable mechanical temperature out-of-limit indicating device includes a mounting base 1, a base 2 connected to the mounting base 1. The mounting base 1 is provided with a plurality of connecting thread through holes which are mainly distributed on the periphery of the mounting base 1 and are provided with countersunk grooves. The mounting base 1 is connected to the base body 2 by means of bolts 11 through these threaded holes. And an external connection threaded blind hole is formed in the middle of the mounting base 1 and used for connecting and fixing the mounting base 1 to a wire clamp.
The inside of the base body 2 is connected with a warning mechanism, a reset mechanism for popping the warning mechanism and a butterfly-shaped bimetallic strip 5 with a kick function. The warning mechanism comprises a warning rod 3, the inside of the warning rod 3 is hollow, and a limiting groove 9 is formed in the outer circumferential surface of the warning rod 3. The shell of the warning rod 3 is provided with a strip-shaped long groove 10. The reset mechanism comprises a reset spring 4, the reset spring 4 is connected in the warning structure, and one end of the reset spring is propped against the bottom of the hole groove of the base body 2.
The base body 2 is internally provided with a hole groove matched with the warning rod 3, the warning rod 3 can be placed in the hole groove, a limiting step matched with the strip-shaped long groove 10 of the warning rod 3 is arranged in the hole groove, and the limiting step can limit the warning rod 3 from rotating and the like to cause the sudden jump failure of the butterfly-shaped metal sheet. And one side of the hole groove is provided with a butterfly-shaped metal sheet placing hole. Specifically, should place the hole and can set up in the bottom of base member 2, place the hole and can let the butterfly sheetmetal place and enter into collectively, be connected the back at base member 2 and installation base 1, restrict the butterfly sheetmetal and drop.
The butterfly bimetallic strip 5 is an annular metal strip and comprises an elastic strip head 6, a jump groove 7 and a supporting part 8, wherein the jump groove 7 is symmetrical along the center of the elastic strip head 6 and is in a butterfly shape. The supporting part 8 is a solid metal sheet, the elastic sheet head 6 is provided with a free end and a connecting end, the connecting end is fixed on the supporting part, the elastic sheet head 6 is inclined, the free end tilts, the elastic sheet head 6 of the butterfly-shaped bimetallic strip 5 is matched with the limiting groove 9 of the warning rod 3, and the free end is finally supported on the warning mechanism and can limit the displacement of the warning rod 3 before sudden jump of temperature rise.
In practical use, as shown in fig. 4-5, when the assembly is completed, the warning rod 3 is placed in the hole groove of the base body 2 together with the return spring 4, and at this time, the return spring 4 is compressed.
