Abstract
The present invention discloses a automobile secure water tank cover including a cover buckles up a water tank opening, a vent peg and a pressure spring pressed on the vent peg; a valve barrel is set on the lower part of the cover which locates inside the water tank opening and seals with inner mouth of the water tank opening; the vent peg is set inside the valve barrel; a core rod passes through the cover; a sliding closure sleeves over the cover; the vent peg fixed on the lower end of the core rod; a wheel gear set on the upper end of the core rod; and a gear ring set on the sliding closure corresponding to the wheel gear. When the water temperature too high, high pressure steam impels the vent peg to jack-up the wheel gear and be separated from the gear ring, the sliding closure breaks away from the driving motion connection with the cover, and the sliding closure slips when being rotated, hence cannot open the water tank cover, and prevent being scalded by hot-water, guarantees usage security.
Description
Technical field
The present invention relates to auto parts and components, particularly to the improvement of tank lid.
Background technique
Radiator is the vitals of car engine cooling system, and the heat and the air of the engine cooling water of high temperature carried out heat exchange, plays the effect of heat radiation.Automobile works overloadingly or travels in hot environment, and engine overheat can't proper functioning when serious.Coolant-temperature gage is too high in the water tank simultaneously, easily causes boiling, water to evaporate in a large number and reduce.Case lid adds water if fetch boiling water this moment, because water, vapour in the water tank have pressure, can spray and scald the people, causes security incident.
Summary of the invention
The object of the invention is to provide a kind of safety type automobile water tank lid that can not be opened when water temperature is too high, to guarantee safety.
The solution of the present invention is: safety water tank cover of vehicle, comprise that buckle buckle closure by its bead is at lid, the valve plug of tank port and be pressed in stage clip on the valve plug, it is characterized in that: the bottom of lid is provided with valve cylinder, valve cylinder is positioned at tank port, seal by the seal washer of its outer and the internal orifice of tank port, valve plug is located in the valve cylinder, be equipped with plug in the lid, lid is with slip lid outward, valve plug is fixed on the lower end of plug, the upper end of plug is provided with gear, and the position of answering with gear mesh on the slip lid is provided with gear ring.
The hole at lid center and plug cross section adopt square or hexagon, perhaps are shaped on spline in correspondence with each other on hole and plug.
Open on the wall of valve cylinder and be shaped on relief hole, be positioned at the top of seal washer.
Advantage of the present invention is: since lid outside sheathed slip lid, the gear ring on the slip lid is in transmission connection by gear, plug and lid, the rotation slip lid can open or close tank lid; When water temperature was too high, high pressure steam promoted valve plug, with gear jack-up, separated with gear ring, and slip lid and lid disengaging are in transmission connection, and slip lid skids when rotating slip lid, and the case lid of can't fetching boiling water has prevented that hot water from scalding the generation of people's accident, guaranteed safe in utilization.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a cross-sectional view of the present invention.
Mark among the figure: 1 end cap, 2 plugs, 3 gears, 4 gear rings, 5 seal washers, 6 water tanks, 7 valve cylinders, 8 screws, 9 valve plugs, 10 relief holes, 11 steam bleeding mouths, 12 stage clips, 13 lids, 14 slip lids.
Embodiment
Referring to accompanying drawing, the bead of lid 13 is shaped on buckle, and the lower edge that turns edge of tank port bead is shaped on the inclined-plane of spiral, and by the button card of buckle and screw inclined plane, lid 13 buckle closures are on tank port, and this linkage structure is the existing structure of water tank.
The bottom of lid 13 is provided with valve cylinder 7, is welded on the inner face of lid 13, and this appliance cover is on water tank 6 time, and valve cylinder 7 is positioned at tank port, and the outer wall of valve cylinder 7 is welded with a back-up ring, and seal washer 5 is arranged under the back-up ring, and the internal orifice step by tank port seals with it.
Lid 13 center drillings are equipped with plug 2 in the hole, hole and plug 2 cross sections adopt square or hexagon, perhaps are shaped on spline in correspondence with each other on hole and plug 2, make it to move axially and can not rotate mutually.
Be with slip lid 14 outside the lid 13, the hole at slip lid 14 centers is greater than the cross section of plug 2, and slip lid 14 can freely rotate with respect to lid 13, also is fixed with end cap 1 on the slip lid 14.
Be provided with valve plug 9 in the valve cylinder 7, valve plug 9 is fixed on the lower end of plug 2 with screw 8.
The upper end of plug 2 is fixed with gear 3, and slip lid 14 is provided with gear ring 4, and is corresponding with gear 3 positions, and gear ring 4 and gear 3 are engageable.
Stage clip 12 is located at 9 of lid 13 and valve plugs, is pressed on the valve plug 9.
During the automobile proper functioning, water temperature is no more than 100 ℃.At this moment, because pressure is little in the water tank, stage clip 12 is depressed valve plug 9, by plug 2 gear 3 of leaving behind, makes it and gear ring 4 engagements.This moment, if gear ring 4 driven gears 3, plug 2 rotated rotary end cover 1 or slip lid 14, finally drove lid 13 and rotated, and can open water tank or it is covered, seals.
When water temperature too high, above 100 ℃, water boiling, vaporization, pressure increases in the water tank, and it is up that water vapor promotes valve plug 9, it is up that plug 2 pushes gear 3, separate with gear ring 4, this moment, slip lid 14 slided over each other with lid 13 as if rotary end cover 1 or slip lid 14, can not drive lid 13 and rotate, prevent from that lid 13 from opening to cause the hot water ejection to hurt sb.'s feelings.
Open on the wall of valve cylinder 7 and be shaped on relief hole 10, be positioned at the top of seal washer 5.Its effect is when water temperature is too high, and valve plug 9 goes upward to the top of relief hole 10, and water vapor can be discharged by original steam bleeding mouth 11 on this Kong Bingjing water tank, bursts to prevent the water case.
