The fluffy eaves extension mechanism of a kind of break campTechnical field
The utility model relates to a kind of break camp, refers in particular to the fluffy eaves extension mechanism of a kind of break camp.
Background technology
In prior art, foldable tent frame generally comprises column, collapsible side lever assembly and collapsible push rod assembly and king-rod; Every root post is provided with a holder that is fixed on column top and pivot bush unit sliding seat on column; Collapsible side lever assembly is at least formed by the pivot joint of two " Z " type poles intersections, and wherein the two ends of " Z " type pole are articulated on the holder of adjacent two root posts, and the two ends of another root " Z " type pole are articulated on the sliding seat of adjacent two root posts; Collapsible push rod assembly is at least comprised of four groups of push rod unit, and each group push rod unit is at least formed by the pivot joint of two poles intersections; A wherein pole one end and the pivot joint of " Z " type pole, another pole one end and the pivot joint of another root " Z " type pole, and the other end of two poles is articulated on king-rod.
During use, foldable tent frame is opened, tent cloth is covered on foldable tent frame and forms tent inner space, and now, the inner space of tent is defined by four root posts, space is relatively narrow and small, conventionally, for expanding the inner space of tent, be generally to adopt the distance expanding between adjacent upright posts, its defect is: need to increase the length that is connected in the collapsible side lever assembly between adjacent upright posts, increase the weight of tent rack; Expand the distance between adjacent upright posts, weaken the intensity of tent.
In view of the described defect of prior art, the inventor develops a kind of fluffy eaves extension mechanism of break camp that overcomes described defect, and this case produces thus.
Utility model content
It is a kind of simple in structure and can expand the fluffy eaves extension mechanism of break camp of tent internal construction that the purpose of this utility model is to provide.
For reaching above-mentioned purpose, solution of the present utility model is:
A fluffy eaves extension mechanism, comprises the first support bar, the second support bar and hound; Hound one end is articulated in column upper end; First support bar one end is arranged on collapsible side lever assembly in rotatable mode, and the other end is arranged on hound stage casing in rotatable mode; Second support bar one end is arranged on adjacent collapsible side lever assembly in rotatable mode, and the other end is arranged on hound stage casing in rotatable mode; Under tent rack deployed condition, the first support bar and the second support bar are propped up hound.
Further, first support bar one end is arranged on collapsible side lever assembly by universal joint, and the other end is arranged on hound stage casing by universal joint; Second support bar one end is arranged on adjacent collapsible side lever assembly by universal joint, and the other end is arranged on hound stage casing by universal joint.
Further, every root post is provided with a holder that is fixed on column top and pivot bush unit sliding seat on column; Collapsible side lever assembly is at least formed by the pivot joint of two poles intersections, and wherein the two ends of a pole are articulated on the holder of adjacent two root posts, and the two ends of another root pole are articulated on the sliding seat of adjacent two root posts; The first support bar and second support bar one end are arranged on respectively on adjacent and two poles sliding seat pivot joint, and the other end is arranged on respectively hound stage casing.
Adopt after such scheme, tent rack is under deployed condition, and the first support bar and the second support bar are propped up hound under the effect of collapsible side lever assembly, thus by the fluffy eaves of tent to external expansion, expand the inner space of tent; During tent folding, the first support bar and the folding under the effect of collapsible side lever assembly of the second support bar, meanwhile, the first support bar and the drop-down hound of the second support bar are packed up it, easy to carry.
