Description
Technical field
The utility model relates to a kind of plastic shoe tree of novel easy-pulling.
Background technology
Existing plastic shoe tree, comprise front metacarpus, rear heel and the connecting portion for being connected front metacarpus and rear heel, in prior art, connecting portion and front metacarpus directly adopt threaded engagement to be connected, and such plastic cement shoe tree in use for some time, easily occurs that the connecting portion of connecting portion and front metacarpus damages, have impact on the normal use of this plastic cement shoe tree, secondly, shoe tree, owing to have employed entity structure, not easily takes out by existing plastic shoe tree from shoes.
Summary of the invention
The technical problems to be solved in the utility model is, providing a kind of by improving the stability that front metacarpus is connected with connecting portion threaded engagement, realizing improve service life on the whole, the plastic shoe tree of the novel easy-pulling can extracted from shoes by shoe tree easily again.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of plastic shoe tree of novel easy-pulling, it comprises front metacarpus, rear heel and the connecting portion for being connected front metacarpus and rear heel, metal connecting piece is embedded with in described front metacarpus, described metal connecting piece is provided with screwed hole axially, the threaded one end of described screwed hole and connecting portion is connected, and the bottom surface of described front metacarpus is provided with cavity, and described cavity extends to form opening towards the rear end of front metacarpus.
Preferred as one, described metal connecting piece is cylinder, and its outer surface is provided with strip groove.
Preferred as one, metal connecting piece is embedded in front metacarpus by the mode of thermoplastic by described metal connecting piece and front metacarpus.
Preferred as one, described metal connecting piece is cylinder, and its outer surface is provided with bar shaped projection.
Preferred as one, metal connecting piece is embedded in front metacarpus by the mode of thermoplastic by described metal connecting piece and front metacarpus.
Preferred as one, the width of described cavity transverse direction is 3/4ths of front metacarpus transverse width.
Preferred as one, the degree of depth of described cavity longitudinal direction is 1/2nd of the longitudinal height of front metacarpus.
After adopting above structure, the utility model compared with prior art, have the following advantages: our inventive point mainly before embedded in the metal connecting piece of the screwed hole be provided with axially in metacarpus, and the threaded one end of screwed hole and connecting portion is connected, instead of connecting portion directly to adopt with front metacarpus and be threaded, threaded engagement before being equivalent to be replaced by the threaded engagement between metal and metal between plastic cement material and metal, thus in greatly degree, improve the service life of threaded engagement, thus improve the service life of this plastic cement shoe tree on the whole, on the other hand, the bottom surface that our inventive point is also embodied in front metacarpus arranges cavity, cavity extends to form opening towards the rear end of front metacarpus, in the process that plastic cement shoe tree is extracted from shoes, air enters and enters into cavity by opening, can accommodating enough air in cavity, the air in cavity is made to act on sole, the power acting on the sole of shoes is comparatively large, thus it is convenient that plastic cement shoe tree is extracted from shoes, more easily.
Wherein, adopt cylindrical metal connecting piece, and arrange strip groove on its outer surface, metal connecting piece is embedded in front metacarpus by the mode of thermoplastic by metal connecting piece and front metacarpus.Being all to make metal connecting piece and front metacarpus realize coordinating securely, preventing metal connecting piece from occurring circumferentially rotating.
Wherein, adopt cylindrical metal connecting piece, and arrange bar shaped projection on its outer surface, metal connecting piece is embedded in front metacarpus by the mode of thermoplastic by metal connecting piece and front metacarpus.Equally also being to make metal connecting piece and front metacarpus realize coordinating securely, preventing metal connecting piece from occurring circumferentially rotating.
Wherein, by the width design of cavity transverse direction be 3/4ths of front metacarpus transverse width; Be 1/2nd of the longitudinal height of front metacarpus by the depth design of cavity longitudinal direction.Be enough large in order to be designed to by the cavity volume of cavity, thus add the inlet of air, the process finally making plastic cement shoe tree extract from shoes is convenient, is more prone to, more laborsaving.
