Description
Technical field
The utility model relates to a kind of foot-operated air-inflating device.
Background technique
Usually two kinds of modes are had to inflation of tire mode, one is Manual inflating mode with automatic pumping mode another kind, automatic pumping normally by air compressor to inflation of tire, air compressor work must have electricity to work, therefore air compressor using scope is more limited, Manual inflating uses more convenient not by the restriction of electric energy for automatic pumping.But existing Manual inflating mode normally hand-operated air-inflating device, hand-operated air-inflating device makes piston rod drive piston press gas thus inflate to tire by hand piston rod.Need people to bend over to inflate when using hand-operated air-inflating device, use inconvenience, working strength is large.
There is use inconvenience in existing hand-operated air-inflating device as can be seen here, the deficiency that working strength is large.
Model utility content
The technical problems to be solved in the utility model exists for existing hand-operated air-inflating device to use inconvenience, and the deficiency that working strength is large, provide a kind of foot-operated air-inflating device to have easy to use, working strength is little.
The utility model is intended to provide a kind of foot-operated air-inflating device, comprise piston cylinder, the first foot treadle, crus secunda pedal and base, described first foot treadle and crus secunda pedal are all positioned at above base, described piston cylinder is positioned on base, described piston is provided with flexible pipe, described hose end is provided with air tube, piston is provided with in described piston cylinder, described upper piston area is provided with piston rod, described piston cylinder upper end is provided with end cap, described piston rod is through end cap, and described piston cylinder lower end is provided with unidirectional air pressure valve, described piston rod upper end and the first foot treadle ball-joint, described base is provided with strut, described strut lower end is fixedly connected with base, post upper and the first foot treadle ball-joint, described first foot treadle top is provided with groove, the projection with groove fit is provided with bottom described crus secunda pedal, described base top is provided with slide slot, slide blocks is provided with between described crus secunda pedal and base, the boss mated with slide slot is provided with bottom described slide blocks, supported spring is provided with between described crus secunda pedal and slide blocks, one end of described supported spring is fixedly connected with crus secunda pedal, the other end is fixedly connected with slide blocks, the end of described base is provided with positioning block, described positioning block is provided with adjusting bolt, described adjusting bolt is threaded with positioning block, described piston cylinder position and positioning block lay respectively at the two ends end of base, strut is positioned in the middle part of base.
Foot-operated air-inflating device in this programme is provided with the first foot treadle and crus secunda pedal, crus secunda pedal can regulate on the first foot treadle in slippage, the foot-operated district that first foot treadle and crus secunda pedal are formed is applicable to the sole of user, pin steps on the first foot treadle makes piston rod promote piston movement, air in piston press piston cavity, makes the air in piston cavity enter in tire through the gentle stylus printer of flexible pipe.Unidirectional air pressure valve plays one-way conduction effect unidirectional air pressure valve when the air pressure in piston cavity increases and cuts out, air in piston cavity is extruded in tire, when the air pressure in piston cavity is negative pressure, unidirectional air pressure valve is opened, and the air of piston cylinder outside is flow in piston cavity.Piston rod and the first foot treadle ball-joint make foot treadle first foot treadle in the process rotated drive piston rod to move up and down.Strut plays support first foot treadle, and strut and the first foot treadle ball-joint are that the first foot treadle can be rotated around articulating point.First foot treadle top is provided with groove, is provided with the projection with matching grooves bottom crus secunda pedal, and projection can slippage in groove, then make crus secunda pedal and foot treadle can relative movement.Supported spring plays a part to support crus secunda pedal, and crus secunda pedal supported spring in the process of rotating together with the first foot treadle is drawn high or compresses.The lower end of supported spring connects slide blocks, owing to being provided with boss bottom slide blocks, slide slot on boss and base matches, because supported spring is all fixedly connected with slide blocks with crus secunda pedal, when then regulating crus secunda pedal position, supported spring moves thereupon, and supported spring moves and drives slide blocks to move.The positioning block that base is established is provided with adjusting bolt, is positioned by the movement direction of adjusting bolt to slide blocks, when slide blocks position by after fixed then the position of crus secunda pedal also just determine.
Compare with the hand-operated air-inflating device of prior art, the utility model is inserted in the valve of tire by air tube, rotating bolt makes movable block move left and right on base to carry out spacing to the position of movable block, slide blocks drives supported spring to move left and right, supported spring drives crus secunda pedal to move, and the foot-operated district that the first foot treadle is become with crus secunda step configuration is applicable to the sole of user.User steps on the first foot treadle makes piston rod move down, supported spring is in extended state, air in the piston cavity that piston rod drives piston to move down piston and piston cylinder are formed is compressed and is pressed in tire by flexible pipe and air tube by the air in piston cavity, and when the air in piston cavity is compressed, unidirectional air pressure valve cuts out.When user steps on crus secunda pedal, crus secunda pedal makes the first foot treadle drive piston rod to move upward, and piston rod drives piston to move up the negative pressure in piston cavity is increased, and unidirectional air pressure valve is opened, and makes to fill slow air in piston cavity.So repeated multiple times the first foot treadle and the crus secunda pedal of jamming on is to tire aerating.
The utility model is adopted the mode that tramps with one's feet and is inflated fairly simple convenience to tire as can be seen here, and user does not need to bend over to inflate, and working strength is little.
Further, described piston cylinder outer wall is provided with spiral chute, and flexible pipe can be wrapped in convenient for collecting in spiral chute.
Further, be provided with Returnning spring between described piston and piston cylinder end cap, Returnning spring helps out to during piston reset.
Further, described slide slot is dovetail groove, and boss planing stability in dovetail groove is better, and dovetail groove can bear certain pressure.
