Abstract
The utility model relates to an end part sealing device with a telescopic link, which comprises the telescopic link and an outer cover, wherein the telescopic link is installed on the outer cover in a telescopic manner; a sealing nozzle is hermetically installed at the end part of the outer cover, and the end part of the sealing nozzle is a convex head made of an elastic material; and a closed opening which can be opened when the telescopic link abuts and contacts is formed on the convex head. The end part sealing device with the telescopic link is convenient to use.
Description
Technical field
The utility model relates to a kind of end seal, and especially a kind of expansion link end seal is such as e-Pointer of Extensible pen core etc.
Background technology
The e-Pointer of existing Extensible pen core comprises the pen cap, pen core and overcoat, and described pen core telescopically is sleeved in the pen cap, is set with overcoat on the pen cap of the external part of described pen core; When the user uses, overcoat is taken off rear use, the problem of existence: if after the user finishes using, forget overcoat is put on, easily causing pen core to solidify can not reuse; Inconvenient when the sealing of above-mentioned overcoat is used, therefore, need a kind of new hermetically-sealed construction to solve the problems referred to above.
Summary of the invention
In order to overcome the deficiency of the use inconvenience that has the expansion link end face seal structure, the utility model provides a kind of expansion link end seal easy to use.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of expansion link end seal, comprise expansion link and overcoat, described expansion link telescopically is installed on the coat, the end part seal of described overcoat is installed sealed mouth, the end of described sealed mouth is the plush copper of elastomeric material, and described plush copper is provided with the closed opening in order to can open when expansion link contacts.
Further, described closed opening is half-open half-and-half type structure.Certainly, also can adopt other similar hatch frames.
Further, described expansion link comprises cylindrical section and leading portion, and the external diameter of described front end is less than described cylindrical section.
Further again, be provided with the to conflict outer convex closure of described closed opening of the junction between described cylindrical section and front end.
Described sealed mouth is installed on the coat by sealing ring.
The beneficial effects of the utility model are mainly manifested in: easy to use, effectively guarantee the sealing state of expansion link end.
Description of drawings
Fig. 1 is the schematic diagram of expansion link end seal.
Fig. 2 is the schematic diagram of plush copper.
Fig. 3 is the structural representation of water-color paintbrush or e-Pointer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 3, a kind of expansion link end seal, comprise expansion link 1 and overcoat 2, described expansion link 1 telescopically is arranged on overcoat 2, the end part seal of described overcoat 2 is installed sealed mouth 3, the end of described sealed mouth 3 is the plush copper 4 of elastomeric material, and described plush copper 4 is provided with the closed opening 5 in order to can open when expansion link contacts.
Described closed opening 5 is half-open half-and-half type structure.Certainly, also can adopt other similar hatch frames.
Further, described expansion link 1 comprises cylindrical section and leading portion, and the external diameter of described front end is less than described cylindrical section.
Further again, be provided with the to conflict outer convex closure 6 of described closed opening of the junction between described cylindrical section and front end.
Described sealed mouth 3 is arranged on overcoat 2 by sealing ring.
The scheme of the present embodiment, with reference to Fig. 3, said structure is applied to e-Pointer or water-color paintbrush, during use, pen core is stretched out described sealed mouth, can write normally, when not using, with pen core retraction, sealed mouth plays good sealing function, can effectively avoid the end of pen core exposed in air and cause the problem that can not reuse; Easy to use, effectively guarantee the sealing state of expansion link end.
