Abstract
The invention discloses a pulling device of a brake cable of a cart. The pulling device of the brake cable of the cart comprises a pressing block (1), a lever bar (2) and a casing pipe (3), wherein the lever bar (2) is arranged inside the inner cavity (41) of a push rod (4), the casing pipe (3) can move up and down to wrap the upper portion of the push rod (4), an opening (42) is formed in the top of the push rod (4), the lower portion of the pressing block (1) stretches into the inner cavity (41) of the push rod (4) through the opening (42) to be connected with one end of the lever bar (2) in a supporting mode, the other end of the lever bar (2) is connected with the brake cable (5), the lever bar (2) is movably connected with the push rod (4) through a rotary shaft (6), and the upper portion of the pressing block (1) is supported on the inner wall of the top surface of the casing pipe (3). The pulling device of the brake cable of the cart has the advantages that when the casing pipe on the push rod is held by the hand and is pressed downward automatically under the action of the gravity, the casing pipe moves downwards to drive the pressing block to be pressed downward, a brake core is pulled upward, and the cart can be moved front and back normally; when the push rod is disengaged from the hand, one end of the lever bar tilts upward due to the self-weight of the lever bar and the casing pipe is driven move upward to return to the original position, namely the brake part is automatically locked by the brake core.
Description
Technical field
The present invention relates to a kind of brake gear manufacture technology field of go-cart, especially refer to a kind of pull unit of go-cart brake cable.
Background technology
Existing a kind of patent No. is 201110194869.0 and is called that the Chinese invention patent of " a kind of doll carriage dead-man's device " discloses a kind of structure, its structure includes left side and the right side that independently is present in the go-cart rear end respectively, each independent braking device comprises that moving position cover, locating bush, wheel seat, a compressing spring, the axle of stopping, upper end carry the line etc. of stopping of cross-peen, the line of stopping directly is connected or connects indirectly by double-deck external member with the axle of stopping, and utilizes go-cart person to be applied to thrust on the handgrip and promotes adjacent stop axle and the realization of stopping between the tooth of stop line and the wheel release of braking; Artificial thrust on handgrip removes, and the spring tension in the wheel seat promotes to stop adjacent stop between the tooth of the swift incision wheel of axle and realizes brake.This dead-man's device has improved the baby's personal safety coefficient in the go-cart and has used the convenience of go-cart.But the shortcoming of this brake gear is, project organization is unreasonable, stretching the position because of brake cable in the brake gear needs handgrip to press down to spur brake cable, so the pulling structure is easy to damage, heavier because of handgrip again, therefore it is also bad that it returns effect again, namely causes braking can not in time checking doll carriage and accident occurring.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 is that a kind of pull unit ingenious, easy to operate, not fragile and the go-cart brake cable that use is sensitive that designs is provided at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of pull unit of go-cart brake cable, comprise the controller that is installed in the 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, the lever bar, sleeve pipe, described lever bar places the inner chamber of push rod, the L shaped inner chamber of the shape of described lever bar and push rod one side is suitable, described sleeve pipe can be up or down be wrapped in the top of push rod wherein, be provided with the opening with the intracavity inter-connection of push rod at described push rod top, the bottom of described briquetting extend into from opening that the end with described lever bar is supported on the inner chamber of push rod, 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, and the end face inwall of the top of described briquetting and sleeve pipe supports mutually.
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 the push rod inner chamber bottom surface.
As improvement, the bottom of described briquetting also can be concaved with groove, an end of described lever bar be end face and groove floor kinematic support together.Thereby it is more accurate, stable that briquetting is contacted with the lever bar.
As improvement, in the inner chamber of described sleeve pipe and be positioned at the elastomer block that also can be provided with reset response on the push rod upper surface of briquetting the right and left position, this elastomer block can be preferably sponge block.
Improve, also can be provided with extruding block on the push rod bottom surface away from a side of lever bar, described sleeve pipe bottom surface is provided with perforate, and an end of described extruding block stretches out the bottom surface of sleeve pipe from perforate.When hand is pressed extruding block, sleeve pipe is moved down, further promote to move on the brake cable and make the brake core keep pulling up state.
Improve, the bottom surface of described extruding block is connected with the more comfortable attached plate of shaking hands again, make shake hands more comfortable.
Improve, described sleeve pipe can be preferably and involutory push rod is wrapped in wherein, and fixed with each other by screw or bolt again.
Improve, the corresponding inner wall shape with sleeve pipe of described briquetting end face shape is suitable again, and is provided with cavity at briquetting end face middle part, and the bottom surface of described sleeve pipe and cavity correspondence position is provided with projection, and described projection can be inserted in the cavity versatilely.
Improve, on the described push rod and the below that is positioned at the lever bar is provided with the limiting stopper of brake cable again, is provided with the position-limited trough of brake cable process in described limiting stopper.
Compared with prior art, pull unit of the present invention comprises briquetting, the lever bar, sleeve pipe, described lever bar places the inner chamber of push rod, the L shaped inner chamber of the shape of described lever bar and push rod one side is suitable, described sleeve pipe can be up or down be wrapped in the top of push rod wherein, be provided with the opening with the intracavity inter-connection of push rod at described push rod top, the bottom of described briquetting extend into from opening that the end with described lever bar is supported on the inner chamber of push rod, 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, and the end face inwall of the top of described briquetting and sleeve pipe supports mutually.This design advantage is: during sleeve pipe on holding push rod, automatically press down owing to the gravity effect, sleeve pipe is moved down and drive briquetting and press down, because the bottom of briquetting contacts with lever bar one end, force an end of lever bar to move down, and the other end that makes the lever bar upwarps and spurs brake cable, and the brake core is upwards pulled up, and realizes normally moving forward and backward of go-cart; And when hand breaks away from push rod, owing to upwarping lever bar one end to drive to move on the sleeve pipe, the deadweight of lever bar automatically resets, the core that namely brakes blocks brake portion automatically, therefore, no matter on the road surface, plane still is the road surface, slope, go-cart needs only and just can stop automatically under no external force effect, thereby has realized the purpose of safe handling; And the present invention is simple in structure, the design is ingenious, easy to operate, flexible, specious, and uses feel very free and relaxed, has reached the control effect processed of brake effectively.
