The base is connected between the grinding disc and the grinding hand tool. Wherein, the quick change back up pad comprises a gap formed between the base and the grinding disc and communicated to the outside, a plurality of air holes communicated with the gap is formed through the base, and the plurality of air holes forms an airflow for performing heat exchange on the grinding disc during a rotation process of the quick change back up pad.
- In one embodiment, the plurality of air holes is circularly disposed in the base. The plurality of air holes is disposed in the outer edge of the base. Further, a distance between any two of the plurality of air holes is the same as each other.
- In one embodiment, shapes of the plurality of air holes are all circular shapes.
- In one embodiment, the base comprises a concave surface facing the gap. In one embodiment, the grinding disc comprises a first assembly portion disposed at the center of a surface of the grinding disc, and the base comprises a second assembly portion disposed at the center of the base and used for the first assembly portion to assemble and fix.
- Compared with conventional implementation, the present invention has the following features through the above embodiments:
- In the present invention, the gap is formed between the grinding disc and the base and the base comprises the plurality of air holes communicated with the gap, such that the airflow may flow into from the gap due to the rotation of the quick change back up pad to bring heat energy generated by the operation of the quick change back up pad to the outside of the plurality of air holes, thereby solving a problem that a grinding disc is difficult to perform heat dissipation since a surface thereof is covered in the conventional implementation.

- Please referring to
FIG. 1 ,FIG. 2 ,FIG. 3 , andFIG. 4 , the present invention provides a quick change back uppad 1. The quick change back uppad 1 can be mounted on a grinding hand tool 2 such that the grinding hand tool 2 performs a grinding operation on an object (not shown) after driving the quick change back uppad 1 to rotate. The quick change back uppad 1 includes agrinding disc 11 and abase 12. Thegrinding disc 11 is mounted on one side of thebase 12 such that agap 13 communicated to the outside is formed between thegrinding disc 11 and thebase 12. Specifically, a surface of thegrinding disc 11 may comprises a ground particle (e.g., metal or a stone grain), and thebase 12 can be made of a elastic material (e.g., rubber). A plurality ofair holes 121 is formed through thebase 12, and the plurality ofair holes 121 is communicated with thegap 13, respectively. In one embodiment, the plurality ofair holes 121 is circularly disposed in thebase 12, as shown inFIG. 4 . A distance between any two of the plurality ofair holes 121 can be the same as each other. If viewed from the assembled structure of thegrinding disc 11 and thebase 12, thegrinding disc 11 comprises afirst assembly portion 111, thebase 12 comprises asecond assembly portion 122, and thefirst assembly portion 111 can be mounted in thesecond assembly portion 122 such that thegrinding disc 11 is fixed to one side of thebase 12, as shown inFIG. 3 . In one embodiment, thefirst assembly portion 111 is a stud, and thesecond assembly portion 122 is a screw hole for the stud (i.e., the first assembly portion 111) to screw and fix. In another embodiment, thefirst assembly portion 111 is a plurality of fitting pieces, and thesecond assembly portion 122 is a plurality of fitting holes for one of the plurality of fitting pieces to fit respectively. - The detailed configuration of the quick change back up
pad 1 can be clearly known from the above technical description. Therefore, the present invention will further describe a use procedure of the quick change back uppad 1 and an implementation generated by the use procedure. During the use procedure of the quick change back uppad 1, thebase 12 is connected between thegrinding disc 11 and the grinding hand tool 2 such that the grinding hand tool 2 drives thegrinding disc 11 to rotate through thebase 12. In one embodiment, thebase 12 comprises anshaft hole 123, the grinding hand tool 2 comprises adrive shaft 21, thedrive shaft 21 can be mounted in theshaft hole 123, and the grinding hand tool 2 can interlock thedrive shaft 21 to drive the quick change back uppad 1 to rotate through a pneumatic drive mode or electric drive mode. When the quick change back uppad 1 in rotation comes into contact with an object surface (not shown) to perform a grinding operation, since thegap 13 is formed between thegrinding disc 11 and thebase 12 and thebase 12 comprises the plurality ofair holes 121 communicated with thegap 13, such that the plurality ofair holes 121 forms an airflow during the rotation process of the quick change back uppad 1. Wherein, the airflow flows from thegap 13 into a space between thegrinding disc 11 and thebase 12 due to the rotation of the quick change back uppad 1, and then brings heat energy generated by the operation of the quick change back uppad 1 to the outside of the plurality ofair holes 121 from between thegrinding disc 11 and thebase 12. In addition, if thegrinding disc 11 is deformed because of extruding the object surface, the airflow flows from one side of thegap 13 having a smaller space towards one side of thegap 13 having a larger space and is discharged by part of the plurality ofair holes 121. Accordingly, the quick change back uppad 1 performs a heat exchange action on thegrinding disc 11 through the airflow generated in the plurality ofair holes 121 to perform heat dissipation, thereby solving a problem that agrinding disc 11 is difficult to perform heat dissipation since a surface thereof is covered in the conventional implementation. Therefore, in order to enable the quick change back uppad 1 to have better heat dissipation effects at the time of the rotation, in one embodiment, as shown inFIG. 4 , shapes of the plurality ofair holes 121 are all circular shapes such that the airflow discharges heat energy smoothly from the plurality ofair holes 121. In addition, the plurality ofair holes 121 can be disposed in the periphery of the base 12 (in other words, the plurality ofair holes 121 is disposed at positions of thebase 12 close to the outer side), such that the airflow can quickly flow to the plurality ofair holes 121 to discharge the heat energy after entering a space between thegrinding disc 11 and thebase 12 from thegap 13. In addition to two embodiments described above, thebase 12 comprises aconcave surface 124 facing thegap 13, and as shown inFIG. 3 , theconcave surface 124 may lengthen thegap 13 between thegrinding disc 11 and thebase 12, thereby increasing the heat dissipation space of the airflow.
