BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a puncture-proof structure for tires, which can be rapidly installed into a tire and is adaptive to various tire types by using fine tuning, thereby ensuring driving safety. 
         [0003]    2. Description of Related Art 
         [0004]    Generally, tires can be categorized into regular tires that have an inner tube therein and tubeless tires without using an inner tube, both of which are not resistant to damages caused by external force. A tire with an inner tube is ready to work when the inner tube is inflated to expand an outer tube of the tire. Upon puncture by a knife or a sharp article, the tire becomes flat and unusable immediately, bringing the driver with much trouble, such as shoving the car. In the case such a tire gets punctured when the car using it is running fast, traffic accidents are likely to happen. On the other hand, tubeless tires are known to be able to defer the tire&#39;s complete flatness upon puncture, so as to provide sufficient buffer time for the driver to drive the car to a nearby repair workshop. While this buffering function does allow a driver with a damaged tubeless tire to safely arrive at a repair workshop, this function can also hinder a car driver from immediately noticing the tire damage as the tire pressure does not drop sharply. In this case, if the car driver is not aware of the tire damage drives his/her car in high speed or on a rugged road, the tire is likely to become unusable immediately and put the driver into the risk of a traffic accident that endangers his/her life. 
         [0005]    In view of the shortcomings of the prior-art devices, the present inventor is concerned about the public traffic safety and has invented numerous novel tire improvements, including many that have been patented in many countries. Nevertheless, instead of being complacent about his achievements, the inventor continues to research and improve his patented inventions and herein provides a further improved simplified structure that can be assembled rapidly in order to benefit the public in terms of driving safety. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention is directed to a puncture-proof structure for tires. Particularly, the puncture-proof structure provides a spare tire body that can be installed to a tire rapidly and is applicable to various tire types by using fine tuning. The tire has its two top inner edges formed with circular hooked portions for engaging with the spare tire body made of serially connected combining blocks. When the tire gets punctured and damaged by a knife or a sharp article, the spare tire body allows the tire to keep work safely. Therein, the spare tire body is a C-shaped member composed of two C-shaped holding pieces. It can be engaged with the hooked portions of the tire rapidly and arm the tire with puncture-proof ability. 
         [0007]    The objective of the present invention is to provide such a puncture-proof structure, wherein the preassembled spare tire body is a C-shaped part that can be directly engaged with the hooked portions of the tire, thereby achieving rapid installation. Besides, a tire using the spare tire body is puncture-proof such that when punctured by sharp articles or knifes, the tire can still work to make safe arrival at a nearby repair workshop. This saves a car driver who has a flat tire from shoving the car along a high-traffic road and risking his/her life, thereby ensuring the public traffic safety.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0024]    The present invention provides an improved puncture-proof structure for tires. Referring to  FIG. 1 , a tire  10  has its two top inner edges formed with hooked portions  101  and is reinforced by cords arranged therein. 
         [0025]    Referring to  FIG. 10 , two C-shaped holding pieces  40  each have a C-shaped body formed with plural spaced locking holes  401  and bumps  402  raised from its inner surface. 
         [0026]    A plurality of combining blocks  20 , as shown in  FIGS. 2, 3 and 4 , is a hollow member with two lateral sides thereof provided with through holes  201  and with its top formed as an engaging valley  202 . The combining block  20  has its two lengthwise ends diagonally formed with projecting portions  203 . An engaging rib  204  is formed above each of the through holes  201  at the two sides of the combining block  20 . Additionally, each of the combining blocks  20  has its bottom provided with embossment. 
         [0027]    Two linking frames  30 , as shown in  FIG. 5  and  FIG. 5A , each of which has two linking plates  31  and a spacer arranged therebetween and is formed into an H-like body. The linking plate  31  has its two ends each provided with a pivot hole  31   a.  Therein, one of the linking plates  31  has its pivot hole  31   a  at one end thereof additionally attached by a bush  32 . 
         [0028]    Referring to  FIG. 6 , a pressing shaft  50  is an axle that has its two ends formed with threaded holes  501 , and has a through hole  502  running radially therethrough. 
         [0029]    A pressing bolt  60 , as shown in  FIG. 7 , is an axle that has its two ends formed with threaded holes  601 , and has a threaded retaining hole  602  running radially therethrough. 
         [0030]    A plurality of connecting members  61 , as shown in  FIG. 8 , each is formed like a humpback bridge with two ends thereof each having a through hole  610 . A rib  612  is formed above the through hole  610 . 
         [0031]    A plurality of first connectors  90 , as shown in  FIG. 9 , has a slat  90   a  and two separated bushes  90   b.    
         [0032]    A plurality of second connector  91 , has a slat  91   a  and two separated threaded aims  91   b  (also referring to  FIG. 14 ). 
         [0033]    When assembled, the threaded arms  91   b  of one second connector  91  are combined with two bushes  90   b  from two different first connectors  90 , and then retained by two nuts  92 , separately. 
         [0034]    Also included are a screw  91   c,  a locking tube  94   
         [0035]    a packing screw  70  ( FIG. 13 ), 
         [0000]    a locknut  71  ( FIG. 13 ), and
 
a plurality of adjusting members  80 , as shown in  FIG. 13 , having a plurality of spaced notches  801  formed at one edge thereof.
 
         [0036]      FIG. 11  is a partially exploded view of a spare tire body formed by the puncture-proof structure. As shown in  FIG. 11  and  FIG. 12 , the two C-shaped holding pieces  40  are retained by the engaging ribs  204  at two edges of the combining blocks  20 . Meanwhile, the locking holes  401  of the two C-shaped holding pieces  40  are aligned with the through holes  201  at two sides of the combining blocks  20 . Then the bushes  90   b  of the first connector  90  (referring to  FIGS. 9 and 14 ) and the threaded arms  91   b  of the second connector  91  are inserted into the locking holes  401  of the two C-shaped holding pieces  40 , respectively, and enter the through holes  201  of the combining blocks  20 . At this time, each bush  90   b  of the first connectors  90  receives one threaded arm  91   b  of the second connector  91 , so that the combining blocks  20  are connected in series. Afterwards, the nuts  92  fix the threaded arms  91   b  of the second connector  91 , so the components are combined into two C-shaped assemblies. Additionally, a screw  91   c  is inserted into the locking holes  401  of the two C-shaped assemblies and the through holes  201  of the combining blocks  20  as preliminarily positioned. Therein, the foremost and the rearmost combining blocks  20  each have a linking frame  30  attached thereto, as also shown in  FIGS. 5, 5A, 11 and 12 . As shown in  FIG. 13 , the space between the two linking plates  31  at one end of the linking frame  30  allows one later wall of one combining block  20  to be received therein, so that when the linking frame  30  and the combining block  20  are assembled, the pivot hole  31   a  and the bush  32  of the linking plate  31  are aligned with the through hole  201  of the combining blocks  20 . The screw  91   c  and one threaded arm  91   b  of the second connector  91  are respectively inserted into the locking holes  401  of the C-shaped holding piece  40 , the pivot holes  31   a  of the linking frame  30 , the through holes  201  of the combining block  20 , the bushes  32  of the linking frame  30 , and the through holes  201  of the combining blocks  20 , and are exposed outside the locking holes  401  of the C-shaped holding piece  40  as preliminarily positioned. The space between the two linking plates  31  at the opposite end of the linking frame  30  allows one later wall of another combining block  20  to be received therein. At this time, the pivot holes  31   a  of the two linking plate  31  are aligned with the through holes  201  of the combining block  20 . Then a pressing shaft  50  and a pressing bolt  60  are inserted into the through holes  201  of the two combining blocks  20 , respectively, as also shown in  FIGS. 5 and 5A . Two screws  100  are inserted into two through holes  610  from two different connecting members  61  and screwed into the threaded holes  501 ,  601  of the pressing shaft  50  and the pressing bolt  60 , respectively. Meanwhile, two additional screws  100  are screwed into threaded holes  501 ,  601  at the opposite end of the pressing shaft  50  and the pressing bolt  60 . Then a bush  90   b  of a first connector  90  is inserted into the other through hole  610  of a connecting members  61 . Thus, the two bushes  90   b  of the first connector  90  receive the threaded aim  91   b  of the second connector  91  and the screw  91   c.  Then nuts  92  are screwed to the threaded arm  91   b  and the screw  91   c  for fixing. The locking tube  94  is inserted into the other through hole  610  of another connecting members  61  and receives the threaded arm  91   b  of the second connectors  91 . Then a nut  92  is screwed to the threaded arm  91   b  for fixing, so as to form the C-shaped spare-tire body  1000 . 
         [0037]    Therein, the two C-shaped holding pieces  40  have the bumps  402  at their inner surface inlaid between the combining blocks  20 , thereby further ensuring the overall stability of the spare-tire body  1000 . 
         [0038]    As shown in  FIGS. 12, 13, 14 and 15 , the engaging valleys  202  of the combining blocks  20  of the spare-tire body  1000  are combined with the hooked portions  101  of the tire  10 . A packing screw  70  is inserted into the through hole  502  of the pressing shaft  50  and screwed into the threaded hole  601  of the pressing bolt  60  at the combining blocks  20  at the front and rear ends of the spare-tire body  1000 , so as to retain the spare-tire body  1000  along the hooked portions  101  of the tire  10 . Afterward, a locknut  71  is screwed to the packing screw  70  for preventing the packing screw  70  from unscrewing. Then the four screws  100  screwed to the spare-tire body  1000  at the threaded holes  501 ,  601  of the pressing shaft  50  and the pressing bolt  60  are slightly unscrewed to allow the notches  801  of the adjusting members  80  to fit on the screws  100 . Afterward, the screws  100  are screwed tight. Therein, the ribs  612  of the connecting members  61  press against the upper edges of the adjusting members  80  so as to firmly secure the adjusting members  80  from escape, thereby provide the tire with puncture-proof capability. 
         [0039]    To sum up, the present invention is effective in preventing puncture and ensuring driving safety with simple configuration that requires significantly reduced manufacturing costs and time and can be assembled easily.
