Summary of the invention
The purpose of this utility model is to provide a kind of making simple, and moulding is quick, lower, the safe and reliable new oil sensor of manufacture cost.
For achieving the above object, the utility model provides following technological scheme: a kind of new oil sensor, comprise housing, and buoyancy aid is installed in the housing, buoyancy aid and metal float shaft are connected as a single entity; The lower end of metal float shaft is exposed at outside the buoyancy aid, the interior one-body molded tinsel that has of housing top wall, one end of tinsel stretches out housing and is connected with wire, the middle part of tinsel forms the hole of passing and contacting with each other for float shaft, and the upper end of float shaft is passed described hole and is equipped with and stops it to withdraw from the limit stoper in this hole.
Above-mentioned tinsel is copper sheet.
Above-mentioned housing top wall inboard forms more than one projection downwards; The front side at housing middle part offers groove.
Above-mentioned limit stoper is split washer, and the bottom of float shaft forms baffle ring, and the split washer at float shaft middle part is with the spacing bottom in float shaft of buoyancy aid.
The end that above-mentioned wire is connected with tinsel is through in the rubber spool, and the outer end of rubber spool is connected with link, and link is fixed on the outlet bolt with coupling nut, and wire passes the outlet bolt, and its end has sheath and outlet joint.
The utility model beneficial effect compared to existing technology is: the interior one-body molded tinsel that has of housing top wall of the present utility model, the left end of tinsel stretches out housing and is connected with wire, tinsel is molded directly within the sensor housing roof, need not other component for fixing such as screw, need not the to worry loosening problem of tinsel and housing has been saved manufacture cost, has reduced process step, be conducive to the environmental protection low-carbon (LC), improved the working life of sensor.
Description of drawings
Fig. 1 is schematic representation of the present utility model.
Fig. 2 is sensing principle figure of the present utility model.
Among the figure: 1, inserts; 2, housing; 3, buoyancy aid; 4, float shaft; 5, rubber spool; 6, link; 7, coupling nut; 8, wire; 9, sheath; 10, outlet joint; 11, baffle ring; 12, tinsel; 13, limit stoper; 21, pipeline positioning part; 22, groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-2, a kind of new oil sensor comprises housing 2, and buoyancy aid 3 is installed in the housing 2, and buoyancy aid 3 is connected as a single entity with metal float shaft 4; The lower end of metal float shaft 4 is exposed at outside the buoyancy aid 3, the interior one-body molded tinsel 12 that has of housing 2 roofs, solved tinsel and housing and after long-time the use, loosening problem has occured, one end of tinsel 12 stretches out housing 2 and is connected with wire 8, wire 8 is connected with the engine ignition primary air, the middle part of tinsel 12 forms the hole of passing and contacting with each other for float shaft 4, and the upper end of float shaft 4 is passed described hole and is equipped with and stops it to withdraw from the limit stoper 13 in this hole.
Above-mentioned tinsel 12 is copper sheet, and the electric conductivity of copper is better than aluminium, and suitable sensor uses.
Above-mentioned housing 2 roof inboards form more than one projection 23 downwards, in the present embodiment, the quantity of projection 23 has three, and be evenly distributed on the housing 2 roof inner side surfaces, when filling it up with machine oil in the motor, buoyancy aid 3 rises to buoyancy aid 3 end face contact tabs 23 under the floating function of machine oil, avoid buoyancy aid 3 end faces and housing 2 roof inner side surfaces contact (buoyancy aid 3 end faces then are not easy to separate with the contact of housing 2 roof inner side surfaces, may cause buoyancy aid 3 can not easy on and off to move); The front side at housing middle part offers groove 22, is convenient to housing inner chamber and outside exchange fluid.
Above-mentioned limit stoper 13 is split washer, and the middle part of float shaft 4 is provided with split washer, and the bottom of float shaft 4 forms baffle ring 11, and the split washer at float shaft middle part is with buoyancy aid 3 spacing bottoms in float shaft.
The end that above-mentioned wire is connected with tinsel is through in the rubber spool 5, and the outer end of rubber spool is connected with link 6, and link is fixed on the outlet bolt with coupling nut 7, and wire passes the outlet bolt, and its end has sheath 9 and outlet joint 10.
