Abstract
The utility model relates to an ejection type ball shape drop recreational parachute, which comprises a parachute body, a parachute line and a parachute bin which is two hollow hemispherical casings; the edge of the two hollow hemispherical casings is provided with a connecting place which causes the two casings be freely opened and closed; the inner side of the two hollow hemispherical casings of the edge connecting place is provided with an arc shape tension resilient piece which connects two casings; the edge of the opening of the two hollow hemispherical casings is provided with the parachute line which is connected with the lower edge of the parachute body; the external side of the connecting place of the edge of the two hollow hemispherical casings is connected with a rubber band which make the casings be ejected to ascend. The parachute bin is pressed by plastic, and two hollow hemispherical casings are hollow hemispheres made of ultra-thin plastic; the connecting place of the two is the uncut plastic, and the arc shape tension resilient piece connecting the inside of the two is the plastic flake whose both ends are connected with the casing to integration; the parachute body is a mushroom parachute body made of plastic or rubber film, and the lower edge of the parachute body is provided with a stiffening ring.
Description
Technical field
The utility model relates to the spherical falling body amusement of a kind of ejection type parachute, belongs to toys.
Background technology
In existing toy parachute, there are (Chinese patent 02289163.3), the rope packaging type of hand throwing type, metallic magnetism or metal spring to penetrate formula, as Chinese patent 00264755.9,96201511.3 or the like.They exist generally that complex structure, hang time are short, time-delay is wayward, can not be in weak points such as peak parachute-opening and manufacturing process complexity.And known products more early then is to add upper trigger with the compression spring, the structure of similar air gun, the anxiety of existence safety.
Summary of the invention
The purpose of this utility model is the toy parachute of the spherical falling body of a kind of ejection type of design.
1, solves parachute short defective of holdup time aloft.
2, solve parachute to the time-delay accuracy of peak with regard to parachute-opening.
3, solve the problem of parachute manufacturing cost.
The technical solution of the utility model: the spherical falling body amusement of this ejection type parachute, comprise that umbrella body, umbrella rope, umbrella storehouse are two hollow hemisphere shape housings, the limit portion of two hollow hemisphere shape housings makes both foldings junction freely, there is circular-arc tension force shell fragment that both are connected in two hollow hemisphere shapes housing inboard, limit portion junction, two hollow hemisphere shape shell nozzle place limit portions have the umbrella rope to be connected with the lower limb of umbrella body, are connected with in the outside, two hollow hemisphere shape housing limit portion junctions to make it launch the rubber band of lift-off.
The spherical falling body amusement of described ejection type parachute, the umbrella storehouse is formed by the plastics compacting, two hollow hemisphere shape housings are slim plastic hollow hemisphere, and both junctions are exactly the plastics that do not cut off, and the circular-arc tension force shell fragment that connects both inboards is the plastic tab that two ends and housing connect as one.
The spherical falling body amusement of described ejection type parachute, the umbrella body is the mushroom umbrella body that is made by plastics or rubber film.
The spherical falling body amusement of described ejection type parachute, the lower limb of umbrella body has stiffening ring.
Advantage of the present utility model:
1, the umbrella storehouse is by a compression moulding of plastics, and two hollow hemisphere shape housings are slim plastic hollow hemisphere, and both junctions are exactly the plastics that do not cut off, and the circular-arc tension force shell fragment that connects both inboards is the plastic tab that two ends and housing connect as one.Alleviate the weight of whole system, make it simple, reasonable, compact.Select to use the polypropylene plastics material, outstanding this material is made the fatigue proof characteristic of plastic hinge, can up to ten thousand times of folding between two hollow hemisphere shape housings and do not rupture.
2, the mushroom umbrella body that is made by plastics or rubber film, foldable one-tenth is small size very, and opens the mushroom umbrella shape that becomes big volume, can postpone the hang time.
One plastics shell fragment is set, it can be opened with motion state is different, close up.
3, the structure of circular-arc shell fragment is of moderate size elastic force, has solved the accuracy of time-delay parachute-opening.When launching peak, elastic force struts hemisphere to shell fragment because of motion state changes actively, reaches the purpose of time-delay parachute-opening.
4, use the abaculus of the mould of the injection mo(u)lding structure of loosing core, make two hemispheres housing, housing junction and the moulding of shell fragment time processing, can at full speed high efficiency production.
5, the design is simple in structure, compact, rationally, processing technology is easy, in light weight.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Fig. 1 is a structural representation of the present utility model: comprise umbrella body 1, umbrella rope 2, the umbrella storehouse comprises two hollow hemisphere shape housings 3,4, the limit portion of two hollow hemisphere shape housings makes both foldings junction 5 freely, two hollow hemisphere shape shell nozzle place limit portions have umbrella rope 2 to be connected with the lower limb 8 of umbrella body 1, there is circular-arc tension force shell fragment 6 to connect in 5 two hollow hemisphere shapes housing inboard, limit portion junction, is connected with in 5 outsides, portion junction, two hollow hemisphere shape housing limits and makes its rubber band that launches lift-off 7.The lower limb 8 of mushroom umbrella body is a stiffening ring.
Concrete structure and operation principle:
1, a bit of the linking up at the edge of two very thin plastic hollow hemisphere made it to become opening and closing ball freely, and install one in the junction both sides and make the two hemispheres can be with the different circular-arc shell fragments that open, close up of motion, select to use the polypropylene plastics material, use the abaculus of the mould of the injection mo(u)lding structure of loosing core, make two hemispheres housing, housing junction and the moulding of shell fragment time processing.Outstanding this material is made the plastic hinge of housing and junction, and fatigue proof characteristic is good, can up to ten thousand times of folding and do not rupture.
2, in addition, make a mushroom umbrella body with as thin as a wafer plastic foil or rubber membrane, and the reinforcement circle that makes at umbrella mouth place, strutted circular state to keep the umbrella mouth.The umbrella mouth is divided into several equal portions.Respectively link a fine rule as the umbrella rope in these places of equalization, and fine rule is divided into two groups,, fasten opening part respectively at two hemispherical shells two groups the other end.
When 3, using, with the choosing of mushroom umbrella body folding, put into hemisphere, two hollow hemisphere shape housings are closed up globulate, a hand is being pinched the ball that closes up, the another hand stretches rubber band, loose one's grip immediately, spheroid with bullet of rubber band in the air, be subjected to supporting out of shell fragment at peak hemisphere, air-flow is deviate from the umbrella body from hemisphere, launches, and landing slowly.
