block 12 includes afirst protruding shaft 121 and a second protrudingshaft 122 protruded outwardly and respectively from both sides of the slidingblock 12 and movably passed between the pair oflinear guide slots 112, wherein the pair of thefirst protruding shafts 121 have a length long enough to pass out from the pair oflinear guide slots 112, and thesliding block 12 has abuffer wheel 123 installed below the center position of thesliding block 12 and corresponding to thebuffer rail 113, so that thebuffer wheel 123 and thebuffer rail 113 are contacted with each other, and thesliding block 12 has asnap groove 124 formed thereon. It is noteworthy to point out that thebuffer wheel 123 of the present invention is a gear or a rubber wheel for engaging or connecting closely with thebuffer rail 113 to perform a linear movement, and thus the present invention uses engagement of thebuffer wheel 123 with thebuffer rail 113 or the property of a larger frictional force to slow down the moving speed of the slidingblock 12. In addition, ahook 1211 is disposed at an end of the first protrudingshaft 121 for hooking with theelastic element 13. - An end of the pair of

closing buffer assembly 1 of the present invention pulls thesliding block 12 by the pair ofelastic elements 13 to perform the returning and closing movements automatically. During the automatic returning and closing process, an action between thebuffer wheel 123 and thebuffer rail 113 slows down the sliding of the slidingblock 12 to achieve the effect of buffering the impact produced during the automatic closing movement. Therefore, the present invention simplifies the structural design and reduces the quantity of high-cost components such as the pneumatic rod or hydraulic rod to lower the manufacturing cost and the future maintenance cost effectively.
