Description
Technical field
The present invention relates to a kind of hand barrow, especially refer to the control device automatic processed on a kind of hand barrow.
Background technology
Existing a kind of patent No. is that 200720060910.4 Chinese utility model patents that are called " baby stroller " disclose a kind of structure, its structure comprises vehicle frame, is installed on the front and back wheel group of carrying the hurdle framework, being installed on vehicle frame top and carrying the push rod between the hurdle framework and be installed on bottom of frame on vehicle frame top, be respectively arranged with braking mechanism on the front and back wheel group, this braking mechanism comprises brake lever, be installed on the brake frame at brake lever two ends, be installed on the brake mount between the brake frame at two ends and be installed on brake combination on brake frame.When baby stroller turns to the downslope road, the user can slam the brake mount that is installed on the rear wheel group by pin, ordering about whole braking mechanism direction backward moves, and the front truck wheels on the drive vehicle frame move backward, make the front and back wheel group move backward simultaneously, thereby make whole baby stroller stop or slowing down front and back wheel speed; Thereby cause wayward faster rotating wheel when avoiding because of walking on the road of slope.but its shortcoming is, this brake device of handcart need to manually be controlled, just can reach the effect that stops or slowing down of hand barrow, be in when this baby stroller under the state of slope pavement, and in the situation that not noting, the adult do not protecting hand barrow, be that hand barrow is under the effect without external force, will slide from below, trend slope, thereby 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 arrives baby's life security, therefore how to realize that hand barrow can self-actuating brake become head of a family's problem very deeply concerned on slope pavement, the applicant has 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 be provide for above-mentioned prior art present situation a kind of design ingenious, sound construction and can not have under the external force state can self-stopping hand barrow control device automatic processed.
the present invention solves the problems of the technologies described above the technical scheme that adopts: the control device automatic processed of this hand barrow, include can with the pillar stiffener of axletree phase support, be provided with vertical cavity in described pillar stiffener, it is characterized in that: be provided with the energy rotary drum in the bottom of described cavity, described cylinder and wheel link together mutually, the center of described cylinder and wheel can be overlapped rotationally and be through in axletree, be provided with jack radially on the periphery of described cylinder, be provided with the inserted link that can move up and down at the cavity that is arranged in the pillar stiffener above described cylinder, the top of described inserted link is connected with stay cord, when described cylinder turns to jack and is positioned at the below of inserted link, the lower end of described inserted link can be inserted in jack and can be arranged in cavity by stay cord is extracted inserted link from jack structure again.
As improvement, the lower end of described inserted link is provided with magnetic patch; Be provided with iron block or the magnet that can attract each other with magnetic patch in the bottom of described jack, perhaps, the lower end of described inserted link is provided with iron block spare, is provided with the magnetic patch spare that can attract each other with iron block spare in the bottom of described jack.
As improvement, when the lower end of described inserted link is set to magnetic patch, also be provided with iron plate or the magnet that can attract each other on the outer surface of cylinder at the described jack back side; Perhaps, when the lower end of described inserted link is set to iron block spare, also be provided with magnetic patch spare on the outer surface of cylinder at the described jack back side.The advantage of this design is: under the effect that loses external force, the iron plate at the jack back side or magnetic patch are when rollers roll, at 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 between magnetic sheet or iron plate in increase inserted link bottom and jack, after cylinder is rolled to 180 degree again, inserted link can be properly inserted in jack, thereby 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 is supported mutually with cavity inwall in pillar stiffener, and the upper support of the lower end of described spring and inserted link together; Described spring is the tubular spring, the top of described inserted link is provided with the annular table terrace, described spring is the top that is placed on inserted link, and the annular table terrace of described spring bottom and inserted link supports mutually, and the bottom surface in the ring part in the upper end of described spring and cavity is supported mutually, the inner chamber that spring is passed in described stay cord lower end is connected with inserted link, and the through hole in ring part is passed and the outside of extending pillar stiffener in the upper end of described stay cord.This design can accurately be inserted in jack inserted link, thereby 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 protruding the button, and the axial hole clipping in described protruding button and inserted link can be fastened togather by dismountable type.
As improvement, the structure that described cylinder and wheel link is optional excellently is: the side that an end of described cylinder extends the pillar stiffener bottom is connected with circle ring disk, is provided with the buckle that can fix with wheel on described circle ring disk.
As improvement, described circle ring disk and the buckle and the cylinder that are positioned on circle ring disk can be preferably disposable injection molded integral structure.Thereby make make more convenient.
Improve, described stay cord can be connected with pressing board on trolley pole by sleeve pipe again.
compared with prior art, the present invention adopts and is provided with vertical cavity in pillar stiffener, be provided with the energy rotary drum in the bottom of described cavity, described cylinder and axletree link, be provided with jack radially on the periphery of described cylinder, be provided with the inserted link that can move up and down at the cavity that is arranged in the pillar stiffener above described cylinder, the top of described inserted link is connected with stay cord, when described cylinder turns to jack and is positioned at the below of inserted link, the lower end of described inserted link can be inserted in jack and can be arranged in cavity by stay cord is extracted inserted link from jack structure again.The advantage of this design is, no matter hand barrow is on the road surface, plane or on slope pavement, as long as under the effect without external force, the inserted link in pillar stiffener will automatic inserting apparatus in jack, hand barrow just can stop automatically like this; Thereby realized the purpose of safe handling, and this device use is laborsaving and light, not only can be used on perambulator, needs on car type that the people nurses but also can be applied to tricycle for the disabled etc.
