Abstract
Propelling pencil, comprise shell, be located at the inner casing in shell and be located at the pressure cap of inner casing upper end, be provided with a pair symmetrical elastomeric element between described shell and inner casing, described elastomeric element is provided with foam-rubber cushion, be provided with air bag in described inner casing, described air bag is provided with stopper.Propelling pencil of the present utility model, structure is simple, effectively protects pen core, resistance toly falls, and is applicable to children and uses.
Description
Technical field
The utility model relates to pencil field, is specifically related to a kind of propelling pencil.
Background technology
Propelling pencil is the stationery that pupil commonly uses, and children use pencil, and protective awareness is poor, often falls on the ground by pencil, causes pen core to rupture, not only wastes resource, also delays child's use.At present, on market, the pattern of propelling pencil is various, but pencil autoprotection performance is poor, so need to research and develop a kind of resistance to propelling pencil fallen.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of propelling pencil, and resistance to falling property is good.
For solving prior art problem, the technical scheme that the utility model is taked is:
Propelling pencil, comprise shell, be located at the inner casing in shell and be located at the pressure cap of inner casing upper end, be provided with a pair symmetrical elastomeric element between described shell and inner casing, described elastomeric element is provided with foam-rubber cushion, be provided with air bag in described inner casing, described air bag is provided with stopper.
As preferably, the thickness of described foam-rubber cushion is 0.02-0.04cm.
As preferably, described elastomeric element is made up of 2-4 spring.
As preferably, the gap outside described foam-rubber cushion and inner casing is 0.01-0.03cm.
As preferably, the length 0.2-0.3cm shorter in inner casing of described foam-rubber cushion.
As preferably, the pen core bore of described inner casing is 0.5mm.
beneficial effect
Containing good buffering effect in propelling pencil of the present utility model, when pencil land, any one side lands, and pen core all can well be protected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model propelling pencil, wherein, and 1. pressure cap, 2. stopper, 3. air bag, 4. foam-rubber cushion, 5. shell, 6. elastomeric element, 7. inner casing.
Detailed description of the invention
embodiment 1
Propelling pencil, comprise shell 5, be located at the inner casing 7 in shell 5 and be located at the pressure cap 1 of inner casing 7 upper end, be provided with a pair symmetrical elastomeric element 6 between described shell 5 and inner casing 8, described elastomeric element is provided with foam-rubber cushion 4, be provided with air bag 3 in described inner casing 7, described air bag 3 is provided with stopper 2.
Propelling pencil of the present utility model, after add pen core in inner casing 7, blows afloat air bag 3, and clogs in rear loading shell 5 with stopper 2.When propelling pencil is dropped, if side lands, foam-rubber cushion 4 and elastomeric element 6 will reduce the impact on ground effectively, protection pen core, if nib lands, pen core can be pricked when upspringing and reduce impact to air bag 3, avoids fracture.
