BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a detachable panel structure, and more particularly to a display panel structure detachable from or attachable with a supporting stand. 
     2. Description of Related Art 
     As the technique is being developed, liquid crystal displays have already broadly used as the displays for computers, television and etc. 
     Please refer to  FIGS. 1A and 1B . A combining seat  12  is installed at the rear end of a general liquid crystal panel  11 . A supporting stand  13   i  is locked up on the combining seat  12  by means of pivoting shafts  132  engaged each with an elastic washer  132  and a nut  133  to allow the combining seat to be pivotally installed on the supporting stand  13  such that the liquid crystal panel  11  is fixed on the supporting stand  13 . However, because the combination structure of the LCD panel  11  and the supporting stand  13  is fixed, when a user needs to detach the LCD panel  11  freely from the supporting stand  13  or hang the panel  11  on a wall on other vertical surface, he is difficult to detach the panel from the supporting stand. Therefore, the positions for locating the panel  11  are extremely limited, and also because the panel  11  cannot be detached from the stand  13  freely, a box for packaging it always is over large so that the production cost cannot be reduced. 
     Therefore, how to make a LCD panel easier to be assembled on or detached from a supporting stand is the main topic of the present invention. 
     SUMMARY OF THE INVENTION 
     One object of the present invention is to provide a detachable panel structure, enabling a panel to be easy to be assembled on or detached from a supporting stand depending on a practical requirement and use occasion. 
     Another object of the present invention is to provide a detachable panel structure, enabling the volume of a package box to be able to be reduced effectively and the production cost further to be lowered when a panel is packed. 
     For attaining to the objects mentioned above, a detachable panel structure according to the present invention comprises a base seat installed on the panel, a sliding mass capable of being slid in the base seat. A base plate accepted in an accepting groove of the base seat can be directly pressed and positioned in the accepting groove by means of the sliding mass movable in the base seat. Whereby, the panel can be easily assembled on or detached from the supporting stand depending on the location and the requirement of its practical use.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to  FIGS. 2 to 5 . A detachable panel structure mainly comprises a base seat  20 , sliding mass  30  and base plate  40 , in which the back face (i.e. the surface faced to a display panel  11 ) is fixed on the back of the display panel  11  by means of fixing elements, such as screws. An accepting groove  22  for accepting the base plate  40  is disposed in the base seat  20  and the opening of the accepting groove  22  is faced to the supporting stand. A fixing raised rib  211  is disposed on an inner side of die accepting groove  22 , and a fixing space is formed between the lower surface of die fixing raised rib  211  and the bottom of the accepting groove  22 . Besides, a sliding groove  23  on the side of the base seat  20  opposite to the fixing raised rib  21  and an opening  231  is formed between the sliding groove  23  and the accepting groove  22  to allow the sliding groove  23  and the accepting groove  22  to communicate with each other. A barricade plate  2311  is extended at the middle of the upper side of the opening  231  along the direction of the panel  11  and the barricade plate  2311  is connected with the bottom of the accepting groove  22 . At least one straight groove  232  is opened at the bottom of the sliding groove  23 . A raised column  2321 , which can be engaged with an elastic element  50 , e.g. a linear spring, is disposed on the rear wall face in the straight groove  232  and extended along the length direction thereof, as  FIGS. 4 and 5  show. An indented portion  233  is opened at the upper end of the wall face at the front end of the straight groove  232 . Besides, a through groove  236  communicated with the bottom of the base seat  20  is opened at each side of the surface of the through groove  236  and an opening  2361  is disposed at the front end of the through groove  236 . Furthermore, the sliding mass  30  is passed through and assembled at the bottom of the sliding groove  23  by means of a communication state existed among the bottom of the base seat  20 , the sliding groove  23  and the accepting groove  22 . After the assembly, a front end part  31  of the sliding mass  30  is extended out of die opening  231  formed by the sliding groove  23  and the accepting groove  22 . Two holding plates  312  and  313  extended toward the center part of the accepting groove  22  are disposed at the upper end of a front end part  31  of the sliding mass  30  and the pitch between the two holding plates  312  and  313  forms a positioning indented portion  314 ; the holding plates  312  and  313  can he pressed against the two flank sides of the barricade plate  2311  in the opening  231  the positioning indented portion  314 , as  FIGS. 4 and 5  show. Besides, the lower surfaces of the holding plates  312  and  313  and the bottom of the accepting groove  22  form a fixing space  315 , as  FIG. 7  shows. Furthermore, long guide rails  32  corresponding to the indented portions  233  opened at the front ends of the straight grooves  232  are projected on the lower surface of the sliding mass  30 ; the number of the long guide rail  32  is same as the one of the straight grooves  232 . The side of the long guide rail  32  corresponding to the straight groove  232  is propped against by an elastic element  50  at the same time to allow the sliding mass  30  to be moved in the sliding groove  23  by means of the spring force of the elastic elements  50  and allow the distance formed between the holding plates  312  and  313  extended from the front end portion  31  of the sliding mass  30  and fixing raised rib  211  can be adjusted, as  FIGS. 3 and 7  show, in which a pair of hooks  34  and  35  extended downward respectively from the two flank sides of the sliding mass  30 . The hooks  34  and  35  enter through grooves  236  through an opening  2361  at the front end of the through groove  236  when the sliding mass  30  is passed through and combined with the sliding groove  23  and are slid in the through grooves  236  opened at the two ends of the sliding groove  23 . Alternatively, long guide notches may be respectively opened on two flank sides or the sliding mass, and a guide piece corresponding to each the long guide notch is disposed on each inner flank side of the base seat. Furthermore, a pull bar  33  is extended upward from the rear end of the sliding mass  30  for a user to exert a force to pull. The base plate  40  is installed at the upper end of a supporting stand  60 , an indented portion  401  is disposed at one side of the base plate  40  corresponding to the barricade plate  2311  extended from the opening for accepting the barricade plate  2311  of the opening  231 . 
     Please  FIGS. 6 to 8 . Align the fixing space  212  formed by the fixing raised rib  211  on the base seat  20  of the panel  11  with the upper end of the base plate  40  when the panel  11  wants to be assembled on the base plate  40 , and then place the upper end of the base plate  40  in the fixing space  212 . Exert a pull force on the pull bar  33  at the rear end of the sliding mass  30  so as to allow the long guide rails  32  disposed on the lower surface of the sliding mass  30  to be able to move in the indented portion  233  of the sliding groove  23  to press to deform the elastic elements  50 . Meanwhile, the sliding mass  30  is moved on the bottom of the sliding groove  23  along the direction of the pull force and the hooks  34  and  35  extended from the two sides of the sliding mass  30  can be moved and pressed on a rear wall face  2362  of the through groove of the sliding groove  236  to cause the holding plates  312  and  313  at the front end portion  31  of the sliding mass  30  to move together with them; this enlarges the distance between the fixing space  212  and the holding plates  312  and  313 . At this time, take the upper end of the base plate  40  placed in the fixing space  212  as an axle center to rotate the base plate  40  an angle, and because the distance between the fixing raised rib  211  and the holding plates  312  and  313  is enlarged, the opposite end (here is the lower end) of the base plate  40  can be accepted in the accepting groove  22  to allow the bottom of the accepting groove  22  to contact with the surface of the base plate  40 , as  FIG. 8  shows. The pull force can soon be released after the base seat  40  is accepted smoothly and completely in the accepting groove  22  to allow the elastic element  50  in the straight groove  232  of the sliding groove  23  to press against the flank side of a long guiding rail  32  by its own recovering elastic force to cause the sliding mass  30  to be moved reversely. Therefore, the positioning indented portion  314  formed between the two holding plates  312  and  313  at the front end part  31  of the sliding mass  30  can be allowed to recover to its original position and pressed against the flank side of the barricade plate  2311  of the opening  231  and the holding plates  312  and  313  at the front end of the sliding mass  30  just press against the surface at on flank side of the base plate  40  when the positioning indented portion  314  is pressed against the flank side of the barricade plate  2311 , as  FIG. 8  shows. The both ends of the base plate  40  are pressed against by the fixing raised rib  211  and the holding plates  312  and  313  to allow the base seat  40  to be accepted and fixed in the fixing spaces  212  and  315  respectively formed by the fixing raised rib  211  and the holding plates  312  and  313 . Therefore, the deviation or the loosing of the base plate  40  does not happen. 
     Vice versa, if the panel wants to be detached from the surface of the base plate  40 , a pull force is exerted again on the pull bar  33  of the sliding mass  33  to cause the holding plates  312  and  313  disposed at the front end of the sliding mass  30  to be moved together to displace to cause the distance between the fixing raised rib  211  and the holding plates to be enlarged so as to allow the base seat  20  to take the upper end of the base plate  40  in the fixing space  212  as a axle center again to rotate an angle reservedly. And then, the base seat  20  can be withdrawn out of the base plate  40 . The pull force can be removed to allow the sliding mass  30  to be recovered back to its original position after the base seat  20  is completely withdrawn out of the base plate  40 . 
     Please refer to  FIGS. 9 and 10 . A chamfering angle is disposed at the upper edge or a middle section of the upper edge of each of the two holding plates  312  and  313  of the sliding mass  30  relatively to the fixing raised rib  211 , as  FIG. 4  shows. The inclined faces formed by the chamfering angle are respectively caused to be guide inclined planes  3121  and  3131 . When the upper end of the base plate is aligned to the fixing space  212  formed under the fixing raised rib  211 , take the upper end of the base plate  40  located in the fixing space as an axle center, rotate the base plate  40  an angle to cause the side edge of the base plate to be pressed against the guide inclined planes  3121  and  3131  disposed at the upper edges of the holding plate  312  and  313 . The long guide rails  32  can be displaced in the indented portions  233  of the straight grooves  232  of the sliding groove  23  through the force exerted on the guide inclined planes  3121  and  3131  to press against the elastic elements  50  to cause them to be deformed. Meanwhile, the holding plates  312  and  313  disposed at the front end of the sliding mass  30  are moved together to displace so that the distance between the fixing raised rib  211  and the holding plates  312  and  313  to be enlarged to allow the base plate  40  to be accepted in the accepting groove  22  completely. 
     After the lower end of the base plate  40  is accepted in the accepting groove  22 , the force exerted originally on the guide inclined planes  3121  and  3131  suddenly disappears. At this time, the elastic element  50  is pressed against and exerts a force on the flank side of each long guide rail  32  at the lower surface of the sliding mass  30  to cause the sliding mass  30  to be displaced to recover to its original position. Thereafter, the holding plates  312  and  313  disposed at the front end of the sliding mass  30  can just be pressed against the surface at one side of the base plate  40  to allow the two ends of the base plate  40  to be accepted and fixed in the fixing spaces  212  and  315  respectively formed by the fixing raised rib  211  and the holding plates  312  and  313  by pressing the fixing raised rib and the holding plates  312 ,  313  respectively on the upper and lower sides of the base plate  40 . 
     As illustrated in  FIG. 4 , grid pieces  234  and  235  are respectively disposed at two opposite inner flank sides of the sliding groove  23  disposed on the base seat  20  and long guide notches  334  and  335  are respectively opened at the corresponding flank sides of the sliding mass  30 . When the sliding mass  30  is displaced by a pull force or the guiding force yielded from the guide inclined planes  3121  and  3131 , the wall faces of the long guide notches  334  and  335  are moved on the surfaces of the guide pieces  234  and  235  to allow the sliding mass to be kept in a fixed axial direction to displace so that the lower surface of the sliding mass  30  is able to be kept contacting with the bottom of the sliding groove  23 . Whereby, the warp phenomenon of the sliding mass  30  originated from a uneven force does not happen. 
     Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
