Description of the invention: [Technical field to which the invention pertains] The present invention relates to a rim, and more particularly to a rim of a structure. [Prior Art] Referring to Fig. 1, there is known a rim 2 for erecting a plurality of light-array light wires 1 and including a ring-shaped and 1_ spaced inner mounting hole 2U. The inner ring wall 21 and the inner ring 3 have a plurality of ports Pm% around the outer ring wall 22 of the inner ring wall 21, and two of the inner ring wall 21 and the outer ring wall u are respectively connected to the left and right sides. The side wall 23 of the side and the outer ring wall 22 and the side wall 23 4 · define the ring groove 220 ' the ring groove 220 is for the tire % installation: the above side wall 23 includes a connection to the inner ring wall The engaging portion 2 of the i, and the outer end portion 232 extending from the engaging portion 231 and corresponding to the annular groove 22g, and the outer side of the side wall 23 have a braking surface 233 facing the greedy (10) block 25. In addition, some rims 2 are also provided with a lining 24 for improving the airtight effect.

P 63 is connected to the outside of the inner wall portion 63 to be spaced apart from the outer ring wall & the outer wall portion 64, and a hollow loop 65 defined by the inner wall portion 63 and the outer wall portion. The radially inner end of the outer wall portion is connected to the connecting portion 61, and has an obliquely extending portion 641 extending obliquely outward from the connecting portion 61, - an outer portion (4) extending upward from the obliquely extending portion (4) And a radially outer end region 643 that extends laterally inwardly from the radially outer end of the outer region 642 and connects the radially outer end of the inner wall portion. The radially outer end region 643 is provided with a plurality of outer portions The elongated venting opening and the venting opening 64G of the surface of the hollow annular passage are radially arranged to surround the entire rim, and the venting opening 64 〇 and the right radial outer end of the left radial outer end region 643 The position of the 640 vent 640 on the area (4) corresponds. When the present invention is in the case of enthalpy, (4) when the external flow is cut through the orifice of the venting hole, the drainage effect is generated and the gas inside the loop is quickly taken out, and the sound is selected and the sound is a ^ The airflow inside the channel 65 is cyclically updated to generate a heat dissipation effect. The towel venting hole _ is disposed on the radially outer end region 643 of the radially outer end of the outer wall 6, and cooperates with the rim of the rim in the centrifugal direction of the rotating cymbal to self-discharge and dissipate heat. 'W3' is a second preferred embodiment of the rim of the present invention having a ventilation and heat dissipation structure; the embodiment 'is substantially identical to the structure of the first preferred embodiment, and also includes a winding around the central axis' The inner ring wall 4 and the outer ring wall and: 200831311 are connected to the side wall 6 on the outer side of the inner ring wall 4 and the outer ring wall 5. The difference between this embodiment and the first preferred example is that The embodiment provides another side wall 6 of the structure, and the vents 640 of the side walls 6 are of a circular hole type. Referring to FIG. 4, a third preferred embodiment of the rim of the present invention has a ventilating structure. The structure of the first preferred embodiment is substantially the same, except that the vent 640 of the present embodiment is disposed on the outer region 642 of the outer wall portion 64 and axially penetrates from the outer portion 642 and communicates with the ring & Of course, there are several ventilating holes arranged on the outer side 642 of the left and right sides. 640 〇 Referring to FIG. 5, the fourth preferred embodiment of the rim with the ventilation and heat dissipation structure of the present invention is applied to a single layer of rim, so the rim of this embodiment is available for a tube and a tire The card is sleeved and includes: an inner ring wall 4, and two side walls 6', and the vent holes 64G are also disposed on the outer side 642 of the side wall 6. As can be seen from the above description, the present invention mainly borrows By arranging ^ 640 65, 65 on the side wall 6 from the venting hole 640, the air flow is cyclically renewed, thereby generating a heat dissipating effect ° ^ 640 $ to limit the scope of the implementation of the present invention, that is, the scope of the application and the description of the invention according to the present invention The simple equivalent changes and modifications made by the content are within the scope of the patent of the present invention.
