Abstract
The utility model relates to a machine-oil alarm triggering device, comprising a shell body. A machine-oil chamber is arranged in the shell body. A floater triggering mechanism is arranged in the machine-oil chamber. An upper contact piece and a lower contact piece are arranged at the upper end and the lower end of the machine-oil chamber. One end of the floater triggering mechanism is normally connected with the upper contact piece. The corresponding position where the lower contact piece is arranged at the lower end of the shell body is provided with a support base body. The floater triggering mechanism comprises a float needle and a floater which is fixedly connected with the float needle. The upper end of the float needle is communicated and connected with the upper contact piece in a slide mode.

Embodiment
As shown in Figure 2, the utility model adopts, a kind of machine oil alarm trigger equipment, include housing 1, be provided with machine oil cavity volume 11 in the housing 1, float trigger mechanism 2 is installed in the machine oil cavity volume 11, the upper and lower side of machine oil cavity volume 11 is provided with, following contact chip 3,4, and float trigger mechanism 2 one ends often are connected with last contact chip 3, described housing 1 lower end is installed down, and the corresponding site of contact chip 4 is provided with support pedestal 5, float trigger mechanism 2 includes float needle 21 and is fixedly connected on float 22 on the float needle 21, and the upper end of float needle 21 is connected with last contact chip 3 slip conductings, the lower end of float needle 21 and pilot hole 51 sliding connections of supporting on the pedestal 5.
The utility model further is set to, and described housing 1 upper end is provided with annular boss 12, and annular boss 12 connects with machine oil cavity volume 11, takes to be provided with the structure of annular boss 12, can make the housing 1 convenient tobacco pipe sleeve pipe 7 that connects.Location copper spare 6 is installed in annular boss 12, fixedlys connected with last contact chip 3 in the upper end of location copper spare 6, and the upper end of float needle 21 is slidingly matched with the location hole 61 of locating on the copper spare 6, and float needle 21 is connected with last contact chip 3 slip conductings by location copper spare 6.The gap that float needle 21 cooperates with location hole 61 is littler with the gap that pilot hole 51 cooperates than float needle 21, has guaranteed that float needle 21 can not make the pilot hole 51 that supports on the pedestal 5 hinder float needles 21 with the contacts of contact chip 4 down when crooked.Offer two grooves 23 on float needle 21 circumferential surfaces, place collar 24 in the groove 23, collar 24 is connected float 22 holdings on the float needle 21.The bottom of float needle 21 is a cone-shaped, following contact chip 4 is installed on the surface of supporting pedestal 5, and an end be positioned at pilot hole 51 under, because float needle 21 lower ends are pointed, make float needle 21 cranks, have crooked, thereby guarantee float needle 21 connect with contact chip 4 down reliable, and also can conducting when there is dirt in contact chip 4 surfaces down.5 offer several mudholes 52 on the support pedestal, and mudhole 52 is distributed in down the periphery of contact chip 4, have avoided the accumulation precipitation of oil dirt, and the machine oil alarm was lost efficacy.
