The utility model relates to a kind of brake gear, especially relates to a kind of brake gear that is applied on the baby carriage; The utility model also relates to a kind of baby carriage.
Background technology
The brake gear of existing baby carriage has multiple, each tool merits and faults.Common brake gear is to utilize to step on to pull inserted tooth to be embedded the teeth groove of trailing wheel, and the releasing of this brake gear must will be stepped on to pull and upwards be triggered, but this is easy to damage vamp or causes scratch.General brake gear, step on and pull for two about being typically provided with, by about two step on to pull the and arranged on left and right sides trailing wheel realized brake control, this structure in case of emergency can't checked two trailing wheels simultaneously, and cause rolling to move easily or spin and cause toppling over, work the mischief.At present, there is the brake gear of " steps on dual brake " on the market, steps on and pull for two about this brake gear is provided with, step on a left side and step on to pull and to realize brake, step on the right side and step on to pull and to realize un-brake, but this allows the operator obscure easily, cause maloperation and produce the generation safety misadventure.
The utility model content
The brake that exists at the brake gear of above-mentioned " steps on dual brake " and the processing ease of un-brake allow the operator obscure this problem, the utility model provides a kind of brake gear, this brake gear only is provided with one and steps on and pull, and can realize " one steps on dual brake, one step on bilingual ".
The utility model brake gear is by the following technical solutions:
A kind of brake gear comprises:
Axletree;
Step on the assembly of pulling, comprise the collar that is socketed on the axletree, be fixed in stepping on of the collar outside and pull, and the projectile body that the collar is resetted, described collar two ends arrange the first arc slope;
Movable sleeve is socketed on the axletree and is positioned at collar both sides, and movable sleeve is provided with the second arc slope of matching with the first arc slope with an end of cover loop contacts, and the described movable sleeve outside is provided with deck;
First spring, an end acts on the opposite side of movable sleeve, and the other end directly or indirectly is fixed on axletree;
The elasticity coupler body, an end directly or indirectly is fixed on axletree, but other end hasp is on deck;
The inserted tooth seat, be fixed in the axletree two ends, comprise the assembling stand that is fixed in the axletree two ends and mounting hole is set, at least part of mounting hole and axially movable inserted tooth of mounting hole relatively of being positioned at, and be positioned at mounting hole and make inserted tooth that second spring that ejects mounting hole trend be arranged, described mounting hole opening is outside, and described second spring is less than the stiffness coefficient of first spring, and described assembling stand also is provided with the through hole that communicates with the mounting hole bottom;
First steel rope passes described through hole, and two ends link to each other with movable sleeve, inserted tooth bottom respectively.
When needs transfer brake gear to braking state, trampling described stepping on pulls, the collar rotates with the axle center, the first arc slope forces movable sleeve mobile laterally, until elasticity coupler body hasp on deck, movable sleeve separates with the collar, and inserted tooth at utmost is positioned at outside the mounting hole, and this moment, brake gear was in braking state.When needs transfer brake gear to the un-brake state, trampling described stepping on pulls, the collar rotates with the axle center, the first arc slope forces movable sleeve mobile laterally, leaves deck until the elasticity coupler body, and first spring is greater than second stiffness coefficient that launches, make movable sleeve mobile until joining with the collar to the inside, simultaneously, inserted tooth at utmost is positioned at mounting hole, and this moment, brake gear was in the un-brake state.
Described brake gear can be realized " one steps on dual brake, one step on bilingual ", and its brake or un-brake all be by to same step on to pull carry out identical operations, simple to operate.
The utility model also provides a kind of baby carriage, and described baby carriage comprises above-mentioned brake gear and rear wheel assemblies, and the wheel inboard of described rear wheel assemblies is provided with the teeth groove that can allow inserted tooth embed.
