Abstract
The present invention relates to a secondary safety device of a pulling cable drive mechanism for a baby carriage, which compromise a main shell body 1, a handle rod 14 and a pulling cable drive mechanism, wherein the handle rod 14 is fixedly connected with both sides of the main shell body 1, and the pulling cable drive mechanism is arranged in the inner chamber of the main shell body 1; a hand knob 17 is arranged at the lower part of the pulling cable drive mechanism, a first shielding hood 2 and a second shielding hood 3 are pivoted on the main shell body 1, a first part gear 7 is arranged on the first shielding hood 2, a second part gear 8 is arranged on the second shielding hood 3, and the first part gear 7 is engaged with the second part gear 8. When the hand knob can not be operated, the lower part of the hand knob can be shielded by the shielding hoods, and hands can not be in contact with the hand knob, so the using safety of a baby carriage is ensured.
Description
Technical field
The present invention relates to a kind of doll carriage, particularly the trailing cable driver train of doll carriage pushing hands bar place setting.
Background technology
In the prior art, doll carriage trailing cable driver train is arranged at the pushing hands bar middle part of doll carriage, trailing cable driver train in the pushing hands bar that it comprises main casing, be fixedly connected with the both sides of main casing, the inner chamber that is arranged at described main casing, the bottom of described trailing cable driver train is for handling knob, when upwards pressing handling knob, two trailing cables (comprising first trailing cable, second trailing cable) in the trailing cable driver train tension pushing hands bar inner chamber, drive folding catch gear by trailing cable and make this mechanism's release, the vehicle frame of go-cart can fold.But when in go-cart, having taken the baby, promote the phenomenon that maloperation can appear in the pushing hands bar, cause vehicle frame folding, jeopardize baby's safety.
Summary of the invention
The object of the invention provides a kind of secondary safety device of doll carriage trailing cable driver train, and it can prevent the maloperation phenomenon.
Technical scheme of the present invention is: a kind of secondary safety device of doll carriage trailing cable driver train, comprise main casing, the pushing hands bar that is fixedly connected with the both sides of main casing, be arranged at the trailing cable driver train in the inner chamber of described main casing, the bottom of described trailing cable driver train is for handling knob, by the first block cover rotating shaft and the second block cover rotating shaft pivotal joint first block cover and second block cover are arranged respectively on the described main casing, described first block cover is provided with first's gear, described second block cover is provided with the second portion gear, first's gear is meshed with the second portion gear, be in when closing up state in first block cover and second block cover, the downside that the bottom retaining of the bottom of described first block cover and second block cover is being handled knob, when first block cover and second block cover were in open mode, the downside of handling knob was left in the bottom of the bottom of described first block cover and second block cover.
The present invention compared with prior art has following advantage:
By stirring one of them block cover, two block covers are opened simultaneously, make operation knob be achieved, when not allowing operation knob, block cover can be kept off below handling knob, and hand can not touch handles knob, and then doll carriage is safe in utilization.
Description of drawings
