FIELD OF THE INVENTIONThe invention relates to a back-clip structure, especially to a back-clip having the structure for hanging a mobile phone and capable of making the display of the mobile phone being directly viewed by the user while the mobile phone is hanging on the waist belt of the user through the back-clip.[0001]
PRIOR ARTWhereas conventional back-clip, please refer to FIG. 1, is provided with a[0002]body1, one side of thebody1 is provided with an embedded groove (not shown in the FIG.), awedge10 is provided movably in proper place of the embedded groove, and thewedge10 projects to the other side of thebody1. The other side of thebody1 is in sequence provided with asliding plate12, anelastic plate14, and aclip piece16, wherein one end of thesliding plate12 projects out of one end edge of thebody1, the other end is against thewedge10. There is anelastic device18 provided between thesliding plate12 and thebody1, such that through pressing thesliding plate12, thewedge10 can be gradually inserted into the other side of thebody1, and while the force pressing on thesliding plate12 is released, thesliding plate12 will be moved to its original position by the elastic force of theelastic device18. One end of theelastic plate14 adjacent to thebody1 is fixed on thebody1, and the other end adjacent to theclip piece16 is fixed to theclip piece16, which makes one end of theclip piece16 adjacent to thewedge10 be against thebody1, such that the back-clip can be clipped on any object.
Further, there is a hanging rivet[0003]2 provided on a mobile phone which can be inserted into the embedded groove, the hanging rivet2 can slide into the embedded groove, and is restricted by thewedge10. Such that after it has slid into the embedded groove, it won't slide out of the embedded groove, the hanging rivet2 is generally provided on the leather case of a mobile phone, or is directly provided on the mobile phone, and the back-clip is generally clipped on the waist belt surrounding the waist of a user, so that the mobile phone can be easily carried.
However, after the mobile phone has been inserted into the embedded groove via the hanging rivet[0004]2, the display of the mobile phone is generally located opposite to the belt, therefore, which makes user cannot view the display of the mobile phone directly, more particularly, while there is anyone calling to the mobile phone, the user cannot view the message displayed on the display; at that time, the user generally must press thesliding plate12 to make the hanging rivet2 slide out of the embedded groove, and then take the mobile phone to the front of eyes to view the display, or directly pull the mobile phone to view the display, thus, makes great inconvenience and trouble in use, especially when pulling the mobile phone directly for viewing the display, it is more possible to make damage to the back-clip or waist belt.
SUMMARY OF THE INVENTIONIn view of these, to improve the disadvantage that the user cannot directly view the display while using conventional back-clip which is clipped on the waist belt of a user, or the back-clip of belt will be damaged due to directly pull the mobile phone for viewing the display. Through long-term hard research and experiment, eventually the inventor develops and designs a back-clip structure of the invention, which is provided with a movable piece, one side of the movable piece is provided with an embedded groove, the other side adjacent to the end edge thereof is pivotally provided with a body, the movable piece can be against the body or can be moved away from being against the body. The side of body which is opposite to the movable piece is provided with a clip piece, and an elastic device is provided between the body and clip piece. Through the elastic force of the elastic device, one end of the clip piece can be exactly against the body making the back-clip being clipped on any object. Such that while the embedded groove is inserted with the hanging rivet provided on the mobile phone, the user of the mobile phone can directly view the display of the mobile phone through lifting the body pivotally.[0005]
One object of the invention is that an axial hole is provided on the movable piece at the place connecting with the body, a restrictive hole is provided on the body at the place connecting with the movable piece, and an axial bar is provided between the axial hole and the restrictive hole, making the movable piece connect movably and pivotally with the body. One side of the restrictive hole near its central part is provided with an arc projection, the restrictive hole is of the shape formed by two holes having two axial centers respectively, such that while the axial bar is located on the axial center of one hole, the movable piece can be against the body, and cannot slide out of the body, if the axle bar is moved to locate on the axial center of the other hole, the body will be able to be rotated pivotally from the movable piece around the axis of the axial bar.[0006]
The present invention is to provide a back-clip structure, please refer to FIG. 2, the present invention is a back-clip structure which is in sequence provided with a[0011]movable piece3, abody4, and a clip piece5, wherein the side of themovable piece3 opposite to thebody4 is provided with an embedded groove (not shown in the FIG.), themovable piece3 is movably provided on one end edge of thebody4, which can be against thebody4, or can be moved away from being against thebody4, between thebody4 and the clip piece5 is provided with anelastic device6, one end of theelastic device6 is fixed on thebody4, and the other end thereof is fixed to the clip piece5, through the elastic force of theelastic device6, one end of the clip piece5 can be against thebody4, such that the back-clip can be clipped on any object, and thus while the embedded groove is inserted with a hanging rivet providing on the mobile phone, through lifting thebody4 pivotally, the user of the mobile phone can directly view the display of the mobile phone hanging on his waist belt through he back-clip.
In present invention, a[0012]wedge30 is provided movably in proper place of the embedded groove, and thewedge30 projects out of the other side of themovable piece3, the other side of themovable piece3 is in sequence provided with asliding plate32, a fixedelastic plate34, wherein one end of thesliding plate32 projects out of one end edge of themovable piece3, the other end of which is against thewedge30, and there is furtherelastic device36 provided between thesliding plate32 and themovable piece3, the fixedelastic plate34 is fixedly connected with themovable piece3 and is movably connected with thewedge30, such that through pressing thesliding plate32, thewedge30 can be gradually inserted into the other side of themovable piece3, and while the force pressing on thesliding plate32 is released, thesliding plate32 will be moved to its original position by the elastic force of furtherelastic device36 while thewedge30 can be moved to its original position by the elastic force of the fixedelastic plate34.
In a preferred embodiment of the present invention, please refer to FIG. 3 and[0014]4, anaxial hole38 is provided on themovable piece3 at the place connecting with thebody4, arestrictive hole40 is provided on thebody4 at the place connecting with themovable piece3, and anaxial bar7 is provided between theaxial hole38 and therestrictive hole40, making themovable piece3 connect movably and pivotally with thebody4, one side of therestrictive hole40 near its central part is provided with anarc projection402, therestrictive hole40 is of the shape formed by two holes having two axial centers respectively, such that while theaxial bar7 is located on the axial center of onehole40, themovable piece3 can be against thebody4, and cannot slide out of thebody4, if theaxial bar7 is moved to locate on the axial center of theother hole40, themovable piece3 will be able to be rotated pivotally away from thebody4 around the axis of theaxial bar7.
