Title: Connecting Structure for Coin Machine

Description:
FIELD OF THE INVENTION 
     The present invent relates to a connecting structure for a coin machine in which at least two positioning tabs are securely retained between at least two limiting recesses and at least two tenons by abutting at least two guiding faces against the at least two positioning tabs so that a receiving funnel is connected with a coin machine firmly. 
     BACKGROUND OF THE INVENTION 
     A conventional connecting structure for a coin machine contains a receiving funnel comprised of a first main body, a male retaining member, and at least one positioning tab. The first main body has the male retaining member disposed on an opening of one end thereof, and the male retaining member has the at least one positioning tab arranged around an outer periphery thereof. A coin machine contains a second main body, a female retaining member, and at least one limiting recess. The female retaining member is fixed on a connecting portion of the second main body and the first main body, and the female retaining member has the at least one positioning tab arranged around an outer periphery thereof. 
     Thereby, the at least one positioning tab is retained in the at least one limiting recess so as to connect the receiving funnel and the coin machine together. However, the at least one position tab of the receiving funnel disengages from the at least one limiting recess after a long period of using time, so the receiving funnel removes from the coin machine easily. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention is to provide a connecting structure for a coin machine in which at least two positioning tabs are securely retained between at least two limiting recesses and at least two tenons by abutting at least two guiding faces against the at least two positioning tabs so that a receiving funnel is connected with a coin machine firmly. 
     To obtain the above objectives, a connecting structure for a coin machine contains: 
     a receiving funnel including a first main body, a male retaining member, and at least two positioning tabs. The first main body has the male retaining member with an opening, the male retaining member is served to retain with a female retaining member of a coin machine and has the at least two positioning tabs arranged around an outer peripheral side thereof. 
     The coin machine includes a second main body, the female retaining member, at least two extending portions, and the at least two limiting recesses. The female retaining member is mounted on a connecting portion of the second main body and the first main body, the female retaining member has the at least two extending portions formed around an outer peripheral side thereof and corresponding to the at least two positioning tabs, each extending portion has a respective one of the at least two limiting recesses defined therein. 
     Each positioning tab has a respective one of at least two guiding faces defined on an end surface thereof, and the respective one of the at least two limiting recesses has a respective one of at least two tenons extending outwardly from one end thereof.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to  FIG. 1 , a connecting structure for a coin machine according to a preferred embodiment of the present invention comprises: a receiving funnel  1  including a first main body  11 , a male retaining member  12 , at least two positioning tabs  13 , and at least two guiding faces  14 . The first main body  11  is used to hold coins and has the male retaining member  12  with an opening, the male retaining member  12  is served to retain with a female retaining member  22  of a coin machine  2  and has the at least two positioning tabs  13  arranged around an outer peripheral side thereof, wherein each positioning tab  13  has a respective one of the at least two guiding faces  14  defined on an end surface thereof so that each positioning tab  13  retains between a respective one of at least two limiting recesses  24  and a respective one of at least two tenons  25  of the coin machine  2 . 
     The coin machine  2  includes a second main body  21 , the female retaining member  22 , at least two extending portions  23 , the at least two limiting recesses  24 , and the at least two tenons  25 . The second main body  21  is applied to control a supply of coins, and the female retaining member  22  is mounted on a connecting portion of the second main body  21  and the first main body  11 , the female retaining member  22  has the at least two extending portions  23  formed around an outer peripheral side thereof and corresponding to the at least two positioning tabs  13 , wherein each extending portion  23  has the respective one of the at least two limiting recesses  24  defined therein, and the respective one of the at least two limiting recesses  24  has the respective one of the at least two tenons  25  extending outwardly from one end thereof. 
     Referring further to  FIGS. 3 and 4 , in assembly, the male retaining member  12  of the first receiving body  11  is retained with the female retaining member  22  of the second main body  21  so that the at least two positioning tabs  13  are locked into the at least two limiting recesses  24 , and then the first main body  11  is rotated so that the at least two guiding faces  14  of the at least two positioning tabs  13  abut against the at least two tenons  25 , such that the at least two positioning tabs  13  are retained between the at least two limiting recesses  24  and the at least two tenons  25 , hence the at least two positioning tabs  13  and the at least two tenons  25  are fixed securely. 
     Accordingly, the connecting structure for the coin machine has the following advantage: 
     The at least two positioning tabs  13  are securely retained between the at least two limiting recesses  24  and the at least two tenons  25  by abutting the at least two guiding faces  14  against the at least two positioning tabs  13  so that the receiving funnel  1  is connected with the coin machine  2  firmly. 
     While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
