Description
Technical field
The present invention relates to a kind of brake gear manufacture technology field of go-cart, especially a kind of pull unit of brake cable of cart.
Background technology
Existing a kind of patent No. is 201110194869.0 and is called that the Chinese invention patent of " a kind of automatic brake device for baby stroller " discloses a kind of structure, its structure includes the left side and right side that are independently present in go-cart rear end, the line etc. of stopping that each independent braking device comprises dynamic position cover, locating bush, wheel seat, compressing spring, axle of stopping, upper end carry cross-peen, line of stopping directly is connected with axle of stopping or is indirectly connected by double-deck external member, utilize go-cart person be applied to hand upper thrust promote stop line and wheel adjacent stop between tooth stop axle and realize brake unlock; When hand removes upper artificial thrust, the spring tension in wheel seat promotes the adjacent realization brake between tooth of stopping of axle swift incision wheel of stopping.This dead-man's device improves the baby's personnel safety factor in go-cart and uses the convenience of go-cart.But the shortcoming of this brake gear is, project organization is unreasonable, stretching position because of brake cable in brake gear needs hand to pull brake cable pressing down, so pull structure to be easy to damage, again because hand is heavier, therefore its to return effect again also bad, namely cause brake not check doll carriage in time and to occur accident.Therefore, the structure of this dead-man's device also needs further improvement.
Summary of the invention
Technical matters to be solved by this invention provides a kind of design ingenious, easy to operate, not fragile for above-mentioned prior art present situation and use the pull unit of sensitive brake cable of cart.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of pull unit of brake cable of cart, comprise the controller be installed in go-cart, it is characterized in that: described controller is installed and is placed on the push rod of go-cart, described controller comprises briquetting, lever bar, sleeve pipe, described lever bar is placed in the inner chamber of push rod, the shape of described lever bar and the inner chamber of push rod side L shape suitable, the top of push rod can be wrapped in wherein by described sleeve pipe up or down, described push rod top is provided with the opening with the intracavity inter-connection of push rod, the bottom of described briquetting is together with opening extend into the inner chamber of push rod and is supported on one end of described lever bar, the other end of described lever bar is connected with brake cable, described lever bar is movably connected by rotating shaft and push rod and connects, the top of described briquetting supports mutually with the end face inwall of sleeve pipe.
As improvement, the maximum displacement that described sleeve pipe moves up and down is greater than the maximum displacement distance between lever bar bottom surface and push rod inner chamber bottom surface.
As improvement, the bottom of described briquetting also can be arranged with groove, and one end of described lever bar is that end face is together with groove floor kinematic support.Thus make briquetting contact with lever bar more accurately, stablize.
As improvement, in the inner chamber of described sleeve pipe the push rod upper surface being positioned at briquetting the right and left position also can be provided with the elastomer block played reset role, this elastomer block can be preferably sponge block.
Improve, the push rod bottom surface of the side away from lever bar also can be provided with extruding block, described sleeve pipe bottom surface is provided with perforate, the bottom surface of sleeve pipe is stretched out in one end of described extruding block from perforate.When hand pressing extruding block, sleeve pipe can be made to move down, promote further brake cable is moved and makes brake core keep pulling up state.
Improve, the bottom surface of described extruding block is connected with more comfortable attached plate of shaking hands again, and makes to shake hands more comfortable.
Improve, described sleeve pipe can be preferably and to be involutoryly wrapped in wherein by push rod again, and by screw or bolt fixed with each other.
Improve, described briquetting top surface shape inner wall shape corresponding to sleeve pipe is suitable, and is provided with cavity in the middle part of briquetting end face, and the bottom surface of described sleeve pipe and cavity correspondence position is provided with projection again, and described projection can be inserted in cavity actively.
Improve, on described push rod and the below being positioned at lever bar is provided with the limiting stopper of brake cable, is provided with the position-limited trough of brake cable process in described limiting stopper again.
Compared with prior art, pull unit of the present invention comprises briquetting, lever bar, sleeve pipe, described lever bar is placed in the inner chamber of push rod, the shape of described lever bar and the inner chamber of push rod side L shape suitable, the top of push rod can be wrapped in wherein by described sleeve pipe up or down, described push rod top is provided with the opening with the intracavity inter-connection of push rod, the bottom of described briquetting is together with opening extend into the inner chamber of push rod and is supported on one end of described lever bar, the other end of described lever bar is connected with brake cable, described lever bar is movably connected by rotating shaft and push rod and connects, the top of described briquetting supports mutually with the end face inwall of sleeve pipe.This design advantage is: when holding the sleeve pipe on push rod, automatically press down due to Action of Gravity Field, sleeve pipe is moved down and drives briquetting to press down, because the bottom of briquetting contacts with lever bar one end, one end of lever bar is forced to move down, and make the other end of lever bar upwarp and pull brake cable, brake core is upwards pulled up, realizes the normal movable of go-cart; And when hand departs from push rod, make due to the deadweight of lever bar lever bar one end upwarp and drive sleeve pipe moves and automatically resets, namely the core that brakes blocks brake portion automatically, therefore, no matter on plane road surface or on slope pavement, as long as go-cart just can stop automatically without under External Force Acting, thus achieves the object of safe handling; And structure of the present invention simple, design ingenious, easy to operate, flexible, specious, and use feel very free and relaxed, effectively reach the control effect processed of brake.
