Description
Technical field
The utility model relates to the armrest on a kind of child's tricycle.
Background technology
Armrest on a kind of child's tricycle, comprise handrail, back support bar, handrail comprises the multistage bonded assembly handrail monomer that rotates, be positioned at the setting that rotates of the handrail monomer at handrail two ends and back support bar, back support bar is inserted on the seat, be provided with lockout mechanism between handrail monomer and the back support bar, lockout mechanism comprises the projection that is slidingly arranged on the handrail monomer, be opened in the groove on the back support bar, in the time of in projection injects groove, handrail monomer and back support bar fix, child is sitting on the seat, handrail, back support bar all is in running condition stably, after projection and groove are separated, the handrail monomer is free to rotate with respect to back support bar, thereby also can freely rotate between handrail monomer and the handrail monomer, then can be according to the next space size of freely regulating handrail of child's body size, but projection and groove in the existing lockout mechanism all are exposed to the outside, cause this structure very not attractive in appearance like this.
Summary of the invention
The purpose of this utility model is to provide the armrest of profile better appearance on a kind of child's tricycle.
In order to reach above purpose, the technical solution adopted in the utility model is: the armrest on a kind of child's tricycle, comprise handrail, back support bar, described handrail comprises the multistage bonded assembly handrail monomer that rotates, be positioned at the setting that rotates of the handrail monomer at described handrail two ends and described back support bar, an end that is positioned at the handrail monomer of described handrail end is set on the described back support bar slidably, the inside of this handrail monomer end, has a circle groove on two one of them parts of parts of described back support bar, form restriction protrusion between the adjacent groove, have on another parts and be used to insert in the described groove with the block piece inconsistent with described restriction protrusion.
Be provided with the elastic component that is used to provide an elastic-restoring force of described handrail monomer between described handrail monomer and the described back support bar.
Have a described circle groove on the described back support bar, the inside of described handrail monomer end has described block piece.
Described block piece has at least a pair of, and described a pair of block piece is oppositely arranged.
The channel opening direction of described groove upwards.
Because the utility model has adopted above technical scheme, its advantage is: in the time of in block piece injects groove, because block piece and restriction protrusion are inconsistent, then handrail monomer and back support bar fix, child is sitting on the seat, handrail, back support bar all is in running condition stably, lift the handrail monomer, the handrail monomer upwards slides with respect to back support bar, block piece and groove are separated, then the handrail monomer is free to rotate with respect to back support bar, and also can freely rotate between handrail monomer and the handrail monomer, then can be according to the next space size of freely regulating handrail of child's body size, when normal use handrail and back support bar, groove, block piece all is positioned at the inside of handrail monomer end, then can not influence the profile of this armrest, so the good looking appearance of this armrest.
Description of drawings
Accompanying drawing 2 is a birds-eye view of the present utility model;
Accompanying drawing 3 is the cutaway view (block piece insert groove in) of accompanying drawing 2 along the B-B direction.
The specific embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1-3, armrest on a kind of child's tricycle, comprise handrail 9, back support bar 3, handrail 9 comprises four sections bonded assembly handrail monomers 1 that rotate, one end of first section handrail monomer 1 rotates with an end of second section handrail monomer 1 and is connected, the other end of second section handrail monomer 1 rotates with an end of the 3rd section handrail monomer 1 and is connected, the other end of the 3rd section handrail monomer 1 rotates with an end of the 4th section handrail monomer 1 and is connected, the setting that rotates of the handrail monomer 1 that is positioned at handrail 9 two ends and back support bar 3, the i.e. other end of first section handrail monomer 1, the other end of the 4th section handrail monomer 1 respectively with the setting that rotates of the back support bar 3 of both sides, seat, an end that is positioned at the handrail monomer 1 of handrail 9 ends is set on the back support bar 3 slidably, as shown in Figures 1 and 2, the end of first section handrail monomer 1, the end of the 4th section handrail monomer 1 is set on the back support bar 3 slidably, has a circle groove 10 on the back support bar 3, form restriction protrusion 11 between the adjacent groove 10, the opening direction of groove 10 upwards, the inside of handrail monomer 1 end has block piece 12, block piece 12 has a pair of, and a pair of block piece 12 is oppositely arranged in the inside of handrail monomer 1 end.When block piece 12 injects in the groove 10, because block piece 12 is inconsistent with restriction protrusion 11, then handrail monomer 1 fixes with back support bar 3, child is sitting on the seat, handrail 9, back support bar 3 all is in running condition stably, lift handrail monomer 1, handrail monomer 1 upwards slides with respect to back support bar 3, block piece 12 is separated with groove 10, then handrail monomer 1 is free to rotate with respect to back support bar 3, and also can freely rotate between handrail monomer 1 and the handrail monomer 1, then can be according to the next space size of freely regulating handrail 9 of child's body size, after the space size of determining good handrail 9, handrail 9 transferred to block piece 12 inject again in the groove 10, then handrail 9, back support bar 3 is in running condition stably again, is provided with the elastic component 8 that is used to provide 1 one elastic-restoring forces of described handrail monomer between handrail monomer 1 and the back support bar 3, have spring pressure ring 6 on the back support bar 3, the two ends of elastic component 8 are against spring pressure ring 6 respectively, on the handrail monomer 1.Up lift handrail monomer 1, block piece 12 and groove 10 are separated, then elastic component 8 is in compressive state, after the space size of determining good handrail 9, unclamp handrail monomer 1, under the elastic-restoring force effect of elastic component 8, handrail monomer 1 glides, and block piece 12 injects in the groove 10 again.Certainly, a circle groove 10 also can be located at the inside of handrail monomer 1 end, and block piece 12 is located on the back support bar 3.Be sitting on the seat child, when normally using handrail 9 and back support bar 3, a circle groove 10, block piece 12 all are positioned at the inside of handrail monomer 1 end, then can not influence the profile of this armrest, so the good looking appearance of this armrest.
