Pendulum bodies are fixed and arranged vertically by a shaft and both ends of the shaft respectively; the lower part of each of the pendulum body are connected into integration via a connection rod; a cradle is arranged on the shaft; the bottom edge of the pendulum body is composed of a short edge structure, and the middle position of the short edge structure is in the shape of a circular arc, and both ends of the arc are the short edges, wherein, the epitaxy of which is as long as the chord. The utility model with the advantages of less components, simple structure of the perambulator after assembled, easy fabrication, low cost, labor saving, comfortable and durable use is an ideal perambulator, and solves defects of complicated structure and high cost of the existing perambulator.

Description

Baby rocking cart

A kind of Baby rocking cart belongs to children special-purpose furniture.

At present, the Baby rocking cart complex structure, required member is more, makes the assembling difficulty, the cost height.The patent No. provides a kind of larry for 89204004 Chinese patent, this larry is made up of pendulum mass, bearing support, ratchet, ratchet, clockwork spring, shift fork, its feature is that the other end of clockwork spring is connected with pendulum mass, pendulum mass, bearing support are equipped with respectively and the cooresponding ratchet of ratchet, ratchet has the contact of interlock, be set in ratchet shaft with the shift fork running-fit that contact touches mutually, all sides of shift fork have balance weight body.The used member of this larry is more, and the assembly relation complexity during making, needs engineering worker, drops into morely, and the cost height of larry because parts are many, belongs to the machinery swing again, easy break-down during use.

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, provide a kind of simple in structure, structural elements is few, be easy to make, cost is low and practical, use laborsaving, comfortable Baby rocking cart.

The utility model is realized with following technical scheme: comprise pendulum mass and cradle, it is by axle, axle two ends difference vertical fixing pendulum mass to be installed, the bottom of two pendulum masses is linked into an integrated entity by connecting rod, be equipped with cradle on the axle, the end of pendulum mass, make that the middle part is circular shape and the arc two ends constitute for the minor face structure of the isometric extend outwards of its string.

The beneficial effect that the utility model had: 1, this larry is linked into an integrated entity by connecting rod by pendulum mass, two pendulum masses of axle, the installation of axle two ends, cradle is installed on the axle to be constituted, belong to framed structure, used member is few, and the material of required usefulness is few, it is less investment, larry after the assembling is simple in structure, is easy to make, therefore, cost is low, is convenient to promote.2, because being the middle part, the end of pendulum mass is circular shape and the arc two ends constitute for the minor face structure of the isometric extend outwards of its string, be integral structure, car body is light, therefore, as long as promote cradle gently, cradle will move, it is moving that cradle in the motion drives pendulum mass, according to the principle of application force and antagonistic force, larry will before and after the swing that do not stop, this utility model is easy to use, and laborsaving.Minor face place at the bottom of pendulum mass is provided with elastomeric layer again, cushions to some extent when it is contacted to earth, and then shaking of larry can be more steady, comfortable, and durable, and can form series of products.

Description of drawings:

Fig. 1 is the Baby rocking cart structural front view;

Fig. 2 is a Baby rocking cart structure side view;

Fig. 3 is the lateral plan of cradle in the Baby rocking cart structure.

Further describe the utility model below in conjunction with accompanying drawing, accompanying drawing has provided the structural representation of a kind of most preferred embodiment of the present utility model, it is by pendulum mass 3, the pendulum mass 3 of present embodiment is designed to equilateral triangle, its end, manufacture that the middle part is circular shape and minor face structure that the arc two ends form for the isometric extend outwards of its string, be drilled with the mounting hole of axle 1 on the top of pendulum mass 3, on the equidistant string of distance line of centers, be drilled with the mounting hole of connecting rod 4, the top of cradle 2 is drilled with the mounting hole of axle 1, it is that the axle mounting hole of cradle 2 from the top is placed in it on axle 1, the vertical respectively plug-in mounting in axle 1 two ends advances in the axle mounting hole of two pendulum masses, 3 upper ends and fixes, it is become one, in the connecting rod mounting hole of two pendulum masses, 3 bottoms, inject two connecting rods 4 again and the bottom of two pendulum masses 3 is linked into an integrated entity make.For reducing material and making its car body light and handy, firm, pendulum mass 3 is made for integral structure, and the middle part also can be made into the hollow structure form.

Claims (1)

1, a kind of Baby rocking cart, comprise pendulum mass and cradle, it is characterized in that by axle, pendulum mass is installed at axle two ends vertical fixing respectively, the bottom of two pendulum masses is linked into an integrated entity by connecting rod, be equipped with cradle on the axle, the end of pendulum mass, make that the middle part is circular shape and the arc two ends constitute for the minor face structure of the isometric extend outwards of its string.
