Description:
FIELD OF THE INVENTION 
     The present invention relates to components used in airbeds, especially to a multiple tubes combination structure for being assembled with air tubes of an airbed, wherein each individual component of the combinational structure has a specific element having a predetermined configuration. Thereby, when it is desired to assemble the combinational structure, it is only necessary to assure the configurations of elements. 
     BACKGROUND OF THE INVENTION 
     A medical airbed has a plurality of airbags. Air is filled into the airbags. In the prior art, the body of the airbed is divided into several sections. The sections are inflated and vented alternatively. Thereby, the inflation condition of the airbed can be changed. There are a plurality of air tubes which are used to supply air to the airbags. Thus, the end of the air pump of the bed has a plurality of tubes for being connected with air pipes connected to the airbags. As a result, the assembling work of the airbed is complicated and thus it is often that some incorrect connections between the air pipes and tubes are induced. Thereby, the alternation of the operations of inflating air and venting air in the airbed is sometimes incorrect. Thereby, the patient lying on the bed will feel uneasy. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a multiple tubes combination structure for being assembled with air tubes of an airbed, wherein a plurality of tubes are assembled in a combinational structure. Each individual component of the combinational structure has a specific element having a predetermined configuration. Thereby, when it is desired to assemble the combinational structure, it is only necessary to assure the configurations of elements. No error occurs. Thereby, the multiple tubes combination structure has a beautiful outlook. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to appended drawings, the multiple tubes combination structure of the present invention is illustrated. In the following, one embodiment of the present invention will be described. 
     Referring to the appended drawings, the combinational structure  1  of multiple tubes includes a base  2 , a buckle seat  3 , a first connecting plate  4 , a tube assembly  5 , a second connecting plate  6 , a toggle  7 , and an outer buckle  8 . 
     One lateral side of the base  2  is used to connect an air valve of an air supply pump. Another lateral side thereof is connected to the buckle seat  3 . One side of the base has a plurality of tracks  22 . The base has a plurality of penetrating tube bodies  21 . One of the tubes is a positioning tube body  211  which has a special shape. 
     The buckle seat  3  is a hollow ring. A plurality of buckling plates  32  are arranged around an outer edge of the buckle seat  3 . The number of the buckling plate  32  is equal to that of the tracks  22 . The buckling plate  32  can be buckled in the track  22 . Thereby, the buckling seat  3  can be combined to the base  2 . A plurality of locking holes  63  are formed on the buckling seat  3 . 
     The first connecting plate  4  is a round plate corresponding to the buckle seat  3 . A plurality of through holes  41  are formed on the first connecting plate  4 . The arrangement and number of the first opening  41  are identical to those of the tube bodies  21 . One of the plurality of through holes  411  is a positioning through hole  411  having a predetermined shape for being inserted by the positioning tube body  211 . One side of the first connecting plate  4  has a plurality of posts  42 . A top of each post  42  has a locking hole  43 . 
     The tube assembly  5  has a plurality of tubes  51 . One of the tubes  51  is a positioning tube  50 . The shape of the positioning tube  50  is like that of the positioning through hole  411 . The upper and lower ends of each tube body  51  are installed with an upper buckling portion  511  and a lower buckling portion  512 , respectively. The upper buckling portion  511  can be inserted into the opening  41  of the first connecting plate  4 . 
     The second connecting plate  6  is a round plate approximately identical to that of the first connecting plate  4 . A plurality of openings  61  corresponding to the openings  41  are formed on the second connecting plate  6 . A positioning opening  611  having a predetermined shape is installed in the opening  61 . The positioning tube  50  in the tube assembly  5  can be inserted into the positioning opening  611 . A plurality of posts  62  are installed at one side of the second connecting plate  6 . The top of each post  62  is installed with a locking hole  63 . 
     A toggle  7  is a hollow tube. The toggle  7  can enclose the tube assembly  5 . The outer periphery of the toggle  7  has a plurality of locking holes  71 . The positions and number of the locking holes  71  are identical to those of the locking holes  31 . 
     The outer buckle  8  has a shape and a structure approximately identical to those of the first connecting plate  4  and second connecting plate  6 . A plurality of openings  81  are formed on the outer buckle  8 . One of the openings  81  is a positioning opening  811  with a predetermined shape. Moreover, the outer buckle  8  has a plurality of locking holes  82  the number of which is equal to that of the locking holes  63 . 
     In assembly, the tube assembly  5  can be buckled between the first connecting plate  4  and second connecting plate  6 . Especially, the positioning tube  50  can be inserted between the positioning openings  411  and  611 . Then the first connecting plate  4  and second connecting plate  6  are locked by screwing a plurality of screws into the locking holes  43 . Then, the toggle  7  encloses the tube assembly  5 . Then, screws  33  screws through the locking holes  31  so that the buckle seat  3  is locked to the toggle  7 . Finally, the tube assembly  5  protruding from the first connecting plate  4  is buckled to the tube bodies  21  of the base  2 . The buckling plates  32  are buckled to the tracks  22 . Thereby, the assembly of the multiple tubes combination structure is complete. 
     The present invention has the following advantages and characteristics. 
     1. The plurality of tube bodies  51  are cylinders and modulized. When it is desired to install the tube bodies  51  with the tube bodies  21  of the base  2 . It is only necessary to assure the configurations of the positioning tubes  50  and  211 . No error occurs, while conventionally, the tubes are assembled one by one. Thereby, the multiple tubes combination structure of the present invention has a beautiful outlook. 
     2. Referring to FIG. 6, when it is desired to combine the air tubes  9  to the present invention, the air tubes  9  are inserted to the protruding ends of the tube assembly  5 . Then, the buckle  8  is assembled. By screwing the screws  83  through the locking holes  82 , the buckle  8  is locked to the second connecting plate  6 . By tightening the opening  81  with the buckling portions  512  of the tube body  51 , the air tubes can be tightly engaged. Obviously, the assembly of the present invention is very easy. 
     3. Since the positioning tube  211 , positioning openings  411 ,  611  and  811  all having special shapes are installed, each component can be assembled correctly. Therefore, a correct modulized structure can be obtained.
