The primary characteristic of the reel of the present invention lies in simple assembling by hooking and fast manufacturing. Therefore, with the injection manufacturing procedure, the period of manufacturing can be greatly reduced to increase the productivity. Further, with the design of simple hooks, the operators at work site can easily understand and perform the assembling sequences.
First, with reference to
The faces on both sides of the spool 11 of the reel 10 are provided with a plurality of means to be hooked 21, respectively. Also, the face on one side of the tray 12 is correspondingly provided with a plurality of hooking means 22. The hooking means 22 and the means to be hooked 21 can be correspondingly hooked with each other, whereby to tightly connect the spool 11 and the tray 12.
The faces on both sides of the spool 11 are provided with a plurality of means to be hooked 21 arranged in an annular form. Each means to be hooked 21 comprises two pieces to be hooked 211 extending inwardly from the wall face of the inner hole. In addition, it can be seen from the drawing that both pieces 211 to be hooked of all means to be hooked 21 are not connected to each other, but an insertion groove 212 having a suitable width is provided in advance between the two pieces 211 to be hooked.
According to the above, the reel 10 of the present invention can be constituted of a spool 11 and two trays 12. Since the faces on both sides of the spool 11 have the same construction for connecting to the tray 12, both trays 12 can be respectively assembled to the surfaces on both sides of the spool 11 in the same manner.
The above-mentioned rib 222 and the insertion groove 212 are used for positioning in the assembling. In addition, as shown in the figure, one set of the rib 222′ and the insertion groove 212′ can be formed into another shape different from that of the other sets. The rib 222′ and the insertion groove 212′ have a larger length or width of extension, so that the spool 11 and the tray 12 cannot be completely assembled if this set of rib 222′ and insertion groove 212′ different from other sets are not correctly aligned and connected to each other. In other words, although the spool 11 and the tray 12 are correspondingly provided with the same amount of the means to be hooked 21 and the hooking means 22, due to the one different set of rib and insertion groove, the spool 11 and the tray 12 are not allowed to be arbitrarily assembled with each other but have to conform to the predetermined orientation to complete the assembling.
The above-mentioned set of rib 222′ and insertion groove 212′ having a different shape can be regarded as the aligning and positioning means for the spool and the tray. The reason is that not only they prevent the relative rotation between the spool 11 and the tray 12, but also they serve as an idiot-proof design in assembling. With such arrangement, the operators can easily recognize it to improve the guiding effect so as to prevent the mistake in assembling.
According to the above, the present invention is directed to a reel 10 constituted of multiple pieces and can be formed by assembling a spool 11 and two trays 12. The spool 11 and the tray 12 are provided on the connecting surfaces with the same amount of the means to be hooked 21 and the hooking means 22 for hooking with each other. In this way, the spool 11 and the tray 12 can be rapidly hooked and connected with each other. Further, among the means to be hooked 21 and the hooking means 22 on the spool 11 and the tray 12, one set of the means to be hooked and the hooking means has an idiot-proof design, that is, they cannot be assembled with each other if only they are correctly aligned. With this idiot-proof design, the operators can easily recognize it to improve the guiding effect so as to prevent the mistake in assembling.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still be occurred to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
