Description
Technical field
The present invention relates to a kind of hand barrow, the control device automatic processed especially on a kind of hand barrow.
Background technology
Existing a kind of patent No. is 200720060910.4 and is called that the Chinese utility model patent of " baby stroller " discloses a kind of structure, its structure comprises vehicle frame, be installed on carrying hurdle framework, be installed on vehicle frame top and the push rod carried between hurdle framework and be installed on the front and back wheel group of bottom of frame of vehicle frame top, front and back wheel group is respectively arranged with braking mechanism, and this braking mechanism comprises brake lever, is installed on the brake frame at brake lever two ends, is installed on the brake mount between the brake frame at two ends and is installed on the brake combination on brake frame.When baby stroller turns to downslope road, user can slam the brake mount be installed on rear car wheels by pin, order about whole braking mechanism direction backward to move, and drive the front truck wheels on vehicle frame to move backward, front and back wheel group is moved simultaneously backward, thus makes whole baby stroller stop or slowing down front and back wheel speed; Thus avoid because causing wayward faster rotating wheel when walking on the road of slope.But its shortcoming is, this brake device of handcart needs manually to control, the stopping that just reaching hand barrow or the effect slowed down, when under the state that this baby stroller is in slope pavement, and when adult does not note and do not protect hand barrow, namely hand barrow is without under the effect of external force, will slide below trend slope, thus cause the generation of contingency, baby's skin and flesh that the lighter is sitting on baby's hand push is injured, severe one also entail dangers to the life security of baby, therefore how to realize hand barrow and self-actuating brake can become head of a family's problem very deeply concerned on slope pavement, the applicant have developed a kind of control device automatic processed of hand barrow finally by unremitting effort for this reason.
Summary of the invention
Technical matters to be solved by this invention provides a kind of to design ingenious, sound construction and can not have under external force state can the control device automatic processed of self-stopping hand barrow for above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above adopted technical scheme: the control device automatic processed of this hand barrow, include can with the pillar stiffener of axletree phase support, vertical cavity is provided with in described pillar stiffener, it is characterized in that: in the bottom of described cavity, be provided with energy rotary drum, together with described cylinder and wheel link mutually, the center of described cylinder and wheel can be overlapped rotationally and be through in axletree, the periphery of described cylinder is provided with radial jack, the inserted link that can move up and down is provided with at the cavity being arranged in the pillar stiffener above described cylinder, the top of described inserted link is connected with stay cord, when described cylinder turn to jack be positioned at the below of inserted link time, the vibrational power flow extracted from jack by inserted link by stay cord again to be inserted in jack in cavity in the lower end of described inserted link.
As improvement, the lower end of described inserted link is provided with magnetic patch; The bottom of described jack is provided with the iron block that can attract each other with magnetic patch or magnet, or the lower end of described inserted link is provided with iron block part, is provided with the magnetic patch part that can attract each other with iron block part in the bottom of described jack.
As improvement, when the lower end of described inserted link is set to magnetic patch, the outer surface of cylinder at the described jack back side is also provided with the iron plate or magnet that can attract each other; Or, when the lower end of described inserted link is set to iron block part, the outer surface of cylinder at the described jack back side is also provided with magnetic patch part.The advantage of this design is: under the effect losing external force, the iron plate at the jack back side or magnetic patch are when rollers roll, first the bottom surface of inserted link is attracted mutually with magnetic sheet or magnetic patch sheet, and inserted link is pulled down automatically, make inserted link and jack distance more close, with the gravitation increased bottom inserted link and in jack between magnetic sheet or iron plate, after cylinder is rolled to 180 degree again, inserted link can be properly inserted in jack, thus it is sensitiveer that inserted link is used, and namely self-actuating brake is more accurate.
As improvement, described inserted link top can be provided with spring, and the upper end of described spring supports mutually with the cavity inwall in pillar stiffener, and the lower end of described spring is together with the upper support of inserted link; Described spring is tubular spring, the top of described inserted link is provided with annular table terrace, described spring is the top being placed on inserted link, and described spring bottom end supports mutually with the annular table terrace of inserted link, and the upper end of described spring and the bottom surface in the ring part in cavity support mutually, described stay cord lower end is connected with inserted link through the inner chamber of spring, and the outside of pillar stiffener is extended in the upper end of described stay cord through the through hole in ring part.This design makes inserted link accurately be inserted in jack, thus it is sensitiveer that inserted link is used, and namely self-actuating brake is more accurate.
As improvement, the lower end of described stay cord can preferably be provided with convex button, and the axial hole clipping energy dismountable type in described convex button and inserted link is fastened togather.
As improvement, the structure that described cylinder and wheel are connected is optional is excellently: the side that pillar stiffener bottom is extended in one end of described cylinder is connected with circle ring disk, described circle ring disk is provided with the buckle that can fix with wheel.
As improvement, described circle ring disk and the buckle be positioned on circle ring disk and cylinder can be preferably disposable injection molded integral structure.Thus make to make more convenient.
Improve, described stay cord is connected with the pressing board on trolley pole by sleeve pipe again.
Compared with prior art, the present invention adopts in pillar stiffener and is provided with vertical cavity, energy rotary drum is provided with in the bottom of described cavity, described cylinder and axletree are connected, the periphery of described cylinder is provided with radial jack, the inserted link that can move up and down is provided with at the cavity being arranged in the pillar stiffener above described cylinder, the top of described inserted link is connected with stay cord, when described cylinder turn to jack be positioned at the below of inserted link time, the vibrational power flow extracted from jack by inserted link by stay cord again to be inserted in jack in cavity in the lower end of described inserted link.The advantage of this design is, hand barrow no matter on plane road surface or on slope pavement, as long as without under the effect of external force, the inserted link in pillar stiffener will automatic inserting apparatus in jack, such hand barrow just can stop automatically; Thus achieve the object of safe handling, and this device uses laborsaving and easily, not only can be used on perambulator, but also can be applied in car type that tricycle for the disabled etc. needs people to nurse.
