The specific embodiment
as shown in accompanying drawing 7-accompanying drawing 9, a kind of child stroller, comprise the go-cart vehicle frame 1 with expanded position and folding position, be arranged at the seat mechanism on described go-cart vehicle frame 1, be arranged on four groups of wheels 2 of described go-cart vehicle frame 1 bottom, be arranged at the braking mechanism with normal danger and un-brake position between at least one group of described wheel 2 and described go-cart vehicle frame 1, described go-cart vehicle frame 1 comprises push rod 4, be arranged at the handle 5 on described push rod 4, described child stroller also comprises and makes described braking mechanism stably be positioned at the elastic component under normal danger, this elastic component is to comprise the first return springs 10 of mentioning in following embodiment and the second return springs 3.
described go-cart vehicle frame 1 also comprise for the trammer, grip and rotate after can control described braking mechanism and be converted to the handle 6 of un-brake position from normal danger, described handle 6 can be set on described handle 5 rotationally, between described handle 6 and described braking mechanism, is provided with trailing cable.The rotational axis line of described handle 6 and its line of centers coincide, and the line of centers of the handle 5 of described handle 6 place sections and the line of centers of described handle 6 coincide.
the rotational axis line of described handle 6 can be to extend along tilting forward and back direction, and parallel with the bilateral symmetry plane of go-cart vehicle frame 1, the rotational axis line that in the present embodiment is described handle 6 extends along left and right directions, will be through the bilateral symmetry plane of go-cart vehicle frame 1.
be provided with the stop gear of described handle 6 rotational angles of restriction between described handle 6 and described handle 5.By stop gear, make the relatively described handle 5 of described handle 6 to rotate in certain angular range.About stop gear so long as can limit the mechanism of two rotational angles between rotatable parts and can use at this.As stop gear can be, be provided with the first limiting section on described handle 6, be provided with two the second limiting sections on described handle 5, the first limiting section is between two the second limiting sections, when described the first limiting section and described second limiting section, when inconsistent, described handle 6 can not relatively described handle 5 rotations.
as shown in accompanying drawing 1-accompanying drawing 3, being connected between trailing cable and handle 6 arranges structure and be: have the elongated slot 7 that length direction extends along the centerline direction of described handle 6 on described handle 5, the length direction of this elongated slot 7 is also that centerline direction along described handle 5 extends; The upper end of described trailing cable is connected with the sliding part 9 with guidepost 8, described guidepost 8 is inserted in described elongated slot 7, there is the first screw inclined plane and the second screw inclined plane that slide for controlling described sliding part 9 on described handle 6, described the first screw inclined plane is contrary with the hand of spiral of described the second screw inclined plane, and form groove between described the first screw inclined plane and described the second screw inclined plane, the depth direction of this groove is to extend along the centerline direction of handle 6.
when described braking mechanism under normal danger, described guidepost 8 is positioned at the innermost of described groove, when described braking mechanism, under the un-brake position or when described braking mechanism, be in the switching process of normal danger and un-brake position, described guidepost 8 is inconsistent with described the first screw inclined plane or described the second screw inclined plane, thereby make the relatively described handle 5 of described guidepost 8 produce displacement, thereby drag described trailing cable, thereby control the braking mechanism be connected with the bottom of trailing cable.The first screw inclined plane and the second screw inclined plane are positive and negative both directions, so handle 6 can rotate by both direction, can realize braking mechanism is converted to the un-brake position in normal danger, in addition, after the following push rod of mentioning 4 commutations, no matter push rod 4 is under the first control position or under the second control position, and the trammer can select the rotation direction that is applicable to oneself to remove to rotate described handle 6.
have the handle inner chamber be connected with described elongated slot 7 on described handle 5, described sliding part 9 is positioned at described handle inner chamber.Described trailing cable also has part will be positioned at described handle inner chamber.The other parts of trailing cable can be also to be arranged in the tube cavity of other rod member of go-cart vehicle frame 1, in the tube cavity of after poppet 12 described as follows.
be provided with between described sliding part 9 and described handle 5 and make described braking mechanism stably be positioned at the first return springs 10 under normal danger, after rotating described handle 6, the trammer discharges again described handle 6, now under the effect of the first return springs 10, described handle 6 is returned to the position before rotating, contribute to braking mechanism is returned under normal danger.
described push rod 4 has two left and right sides sections that lay respectively at described go-cart vehicle frame 1, described handle 5 is arranged between the upper end of described push rod 4 of both sides, in the present embodiment, the described push rod 4 of both sides is integrated with middle described handle 5, and forms U-shaped.
the bottom of described push rod 4 has axial line extend and first rotating shaft that described push rod 4 can rotate around it along left and right directions, described push rod 4 has the first control position and the second control position, when described push rod 4 is positioned under the first control position, described handle 5 is positioned at the rear of described seat mechanism, when described push rod 4 is positioned under the second control position, described handle 5 is positioned at the place ahead of described seat mechanism, be provided with on described go-cart vehicle frame 1 and make described push rod 4 stably be positioned at the lockout mechanism under the first control position or the second control position.Without diagram, described lockout mechanism is not invention main points of the present invention, so long as two parts that rotate can be locked in to two lockout mechanisms under control position, can use, be affiliated to section and second and be affiliated to section as had first on the parts except push rod 4 of go-cart vehicle frame 1, and there is hook on push rod 4, when described push rod 4 is positioned under the first control position, described hook is hooked in first and is affiliated in section, when described push rod 4 is positioned under the second control position, described hook is hooked in second and is affiliated in section.
on described handle 5, be provided with for controlling the control mechanism of described lockout mechanism release.Operate described control mechanism, make above-mentionedly for described push rod 4 being locked in to the lockout mechanism release of the first control position or the second control position, push rod 4 can be changed between the first control position and the second control position.Control mechanism can be that activity arranges a button on handle 5, is provided with the push rod trailing cable between button and lockout mechanism, thereby press described button, by this push rod trailing cable, controls described lockout mechanism.
