Abstract
The utility model discloses a plastic shoe tree, it include preceding palm portion (1), back heel (3) and be used for connecting before the palm portion (1) and back connecting portion (2) of heel (3), metal connecting piece (4) have been inlayed in the preceding palm portion (1), be equipped with axle ascending screw hole (401) on metal connecting piece (4), the one end screw thread fit connection of screw hole (401) and connecting portion (2). The utility model has the advantages that through the stability of palm portion before improving with connecting portion screw thread fit connection to realize improving on the whole shoe tree life.
Description
Technical field
The utility model relates to a kind of plastic cement shoe tree.
Background technology
Existing plastic cement 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, such plastic cement shoe tree in use for some time, easily occur that the connecting portion of connecting portion and front metacarpus damages, have impact on the normal use of this plastic cement shoe tree, cause the service life of shoe tree short.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of by improving the stability that front metacarpus is connected with connecting portion threaded engagement, thus realizes the plastic cement shoe tree improving service life on the whole.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of plastic cement shoe tree, 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, and the threaded one end of described screwed hole and connecting portion is connected.
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.
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.
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.
