Abstract
The invention discloses a slipping-prevention baby stroller provided with an M-shaped normally closed brake device which can effectively prevent a baby stroller slipping accident from happening. According to the technical scheme, wheel axles of the baby stroller are installed on wheel forks and rotate along with wheels, and the wheel forks and a stroller body are fixed together. One end of each one of two brake blocks is arranged on a brake block fixing pin in a sleeved mode, and the other end of each one of the two brake blocks is connected with a connecting rod. The two brake blocks and the two connecting rods are connected to form a symmetric M shape. One end of each steel wire is fixedly connected with a connecting rod pin, and a spring is arranged on the steel wire between each connecting rod pin and a corresponding fixing plate in a sleeved mode. At ordinary times, because the springs push the connecting rod pins to drive the connecting rods, the two brake blocks swing inwards and meanwhile suspend the wheel axles. The other end of each steel wire is fixedly connected with brake handles. When the baby stroller is pushed, the brake handles are clenched by the hands, the steel wires can drive the connecting rod pins to compress the springs, so that the connecting rods drive the two brake blocks to swing outwards, and the wheel axles are released. The brake handles are released, and then the two brake blocks can automatically suspend the wheel axles.
Description
Technical field:
Patent of the present invention relates to a kind of doll carriage, specifically, especially relates to a kind of doll carriage of anti-slip slope.
Background technology:
Present doll carriage does not generally have brake gear, even if some doll carriage has brake gear, while needing to stop, specially brake gear is pinned yet.Sometimes, because doll carriage does not have brake gear or forgotten pinning brake gear, can cause doll carriage to slip slope accident, the casualty that doll carriage slips into korneforos together with baby the most seriously occurred.
Summary of the invention:
The object of patent of the present invention is to provide a kind of doll carriage of anti-slip slope, with the normally closed brake gear of " M " shape, can effectively prevent that doll carriage from slipping the generation of slope accident.
In order to achieve the above object, the technical scheme of patent of the present invention is: a kind of doll carriage of anti-slip slope is made up of wheel, brake shoes set pin, wheel shaft, brake shoes, connecting rod pin, connecting rod, connecting pin, spring, adapter plate, steel wire casing, steel wire, wheel fork, handle setting plate, brake handle, lever pin, go-cart handrail, vehicle body etc.
The wheel shaft of patent of the present invention is arranged on wheel fork, and wheel is arranged on wheel shaft, and wheel shaft rotates with wheel, and wheel fork and vehicle body are fixed together.Wheel fork end is fixed with brake shoes set pin, and one end of two brake shoes is enclosed within brake shoes set pin, and brake shoes can inwardly or outwards swing around brake shoes set pin, and the other end of brake shoes is connected with connecting rod by connecting pin.Two connecting rod connecting rod pins that are connected with two brake shoes respectively link together.Two brake shoes and two connecting rods connect into symmetrical " M " shape by connecting pin and connecting rod pin respectively.Symmetrical " M " shape, as long as the movement of control link pin just can make two connecting rods inwardly drive two brake shoes or outwards swing simultaneously, embraces or decontrols wheel shaft.One end and the connecting rod pin of steel wire are fixed together, and on the steel wire between connecting rod pin and adapter plate, cover has spring, and connecting rod pin is withstood in one end of spring, and the other end of spring withstands adapter plate.Adapter plate and wheel fork are fixed together, and the one side of adapter plate is used for withstanding spring, and the another side of adapter plate is used for withstanding steel wire casing.In the middle of adapter plate, have threaded hole of steel, steel wire passes from threaded hole of steel.At ordinary times, because spring promotes connecting rod pin drivening rod, two brake shoes inwardly swing, and two symmetrical brake shoes are embraced wheel shaft simultaneously, and wheel can not rotate, and can prevent that doll carriage from slipping slope.The other end and the brake handle of steel wire are fixed together, and brake handle is arranged in handle setting plate by lever pin.Handle setting plate and go-cart handrail are fixed together, and steel wire empty set is in steel wire casing, and steel wire casing withstands handle setting plate, and steel wire casing length direction can not compress.While promoting doll carriage, with holding tight brake handle, brake handle can rotate around lever pin, because steel wire casing length direction can not compress, brake handle drives steel wire outwards to stretch, and the other end meeting drivening rod pin Compress Spring of steel wire also makes two connecting rods drive two symmetrical brake shoes outwards to swing simultaneously, and two brake shoes are decontroled wheel shaft simultaneously, now, doll carriage can freely be carried out.As long as decontrol brake handle, under the effect of spring, two brake shoes can be embraced wheel shaft automatically, and wheel can not rotate, and can prevent that doll carriage from slipping slope.
Patent of the present invention is compared with the prior art:
Present doll carriage does not generally have brake gear, even if some doll carriage has brake gear, while needing to stop, specially brake gear is pinned yet.
The doll carriage on a kind of anti-slip slope that patent of the present invention provides, with the normally closed brake gear of " M " shape, can prevent that doll carriage from slipping the generation of slope accident effectively.
Accompanying drawing explanation:
Fig. 1 is the structural representation of patent of the present invention;
Fig. 2 is the local enlarged diagram of patent of the present invention.
In above-mentioned accompanying drawing, the meaning of each numbering is: 1: wheel 2: brake shoes set pin; 3: wheel shaft, 4: brake shoes; 5: connecting rod pin; 6: connecting rod; 7: connecting pin 8: spring; 9: adapter plate; 10: steel wire casing 11: steel wire, 12: wheel fork; 13: handle setting plate; 14: brake handle 15: lever pin; 16: go-cart handrail; 17: vehicle body.
The specific embodiment:
Below in conjunction with accompanying drawing, patent of the present invention is further described.
Refer to Fig. 1~Fig. 2: a kind of doll carriage of anti-slip slope, comprise wheel (1), brake shoes set pin (2), wheel shaft (3), brake shoes (4), connecting rod pin (5), connecting rod (6), connecting pin (7), spring (8), adapter plate (9), steel wire casing (10), steel wire (11), wheel fork (12), handle setting plate (13), brake handle (14), lever pin (15), go-cart handrail (16), vehicle body (17).
