New description: [New technical field] This creation is about the kind of reply buffering device, especially the two kinds of furniture that are moved to open or close, so that the eyes are buffered when closed. The effect of the external furniture slide rail recovery buffer: set. [Prior Art] γ-like design is a relatively movable furniture, such as a cabinet and a drawer located in the eight inner cymbals, which can be arranged between the cabinet and the drawer - a cushioning device to alleviate the speed when the drawer is closed. The forgiveness caused a strong collision with the cabinet due to the excessive speed. Referring to the sixth figure, a prior art recovery buffer device (70) mainly includes a substrate (71), a spring (72) m moving piece (73); the matching is shown in the seventh figure, the substrate (71) is a long-shaped plate body for locking on the inner wall surface of the cabinet (not shown), so that the two ends of the substrate (71) are respectively a closed end and an open end. A tube body (711) is formed on the bottom side of the substrate (71) near the closed end, and a shaft rod (712) is bored in the tube body (711), and the shaft rod (712) is disposed in the tube body (711). One end portion is provided with a piston that can support the inner wall surface of the official body (711), and the other end of the shaft (7彳2). The dog extends to the outside of the body (711) to form a gas pressure bar, and a sliding groove (713) is formed on the opposite sides of the substrate (71彳) near the opening end. One end of the open end of the substrate (71) is bent upward to form a positioning portion (714); the elasticizing (72) is disposed on the top side of the substrate (71), and corresponds to the M359248 end of the closed end of the substrate (71) and the substrate (71) The interlocking pieces (73) are respectively disposed on the opposite sides of the substrate (7彳), and the sliding grooves (713) are formed at the opposite sides of the substrate, and the inner surfaces of the connecting pieces (73) are respectively protruded The at least one convex guiding portion (731) is formed between the corresponding sliding grooves (713) of the substrate (71), and the bottom side of the connecting piece (73) is formed. a fastening portion (732), wherein the end of the shaft (712) and the other end of the spring (72) are respectively clamped and fixed between the two interlocking pieces (73), so that when the linking piece (73) is along When the sliding groove (713) of the substrate (71) moves, the spring (72) and the shaft (71 2) can be pulled simultaneously. When a drawer in the above-mentioned cabinet is in a folded state, it is connected to the fastening portion (732) of the linkage piece (73) through a driving block; when the drawing is opened, it is driven by the driving block. The linking piece (73) moves along the sliding groove (713) of the substrate (7), while pulling the magazine (72) and the shaft (7 cut until the convex guiding portion (731) of the linking piece (73) moves After entering the positioning portion (714) of the chute (71 3), the linking piece (73) is read to be detached from the driving block, and then the drawer can continue to move until fully opened; thereafter, when the drawer is closed, the reverse When the driving block is driven, the driving block is again brought into phase with the fastening portion (732) of the interlocking M73), and the convex guiding portion (731) of the linking piece (73) is driven away from the substrate (71). The positioning portion (714), and then the spring is called the elastic restoring force to pull the linking piece (73) to move 'and the piston also produces a cushioning effect on the substrate (7) of the substrate (7), so that the interlocking piece ( 73) and the drawer is gently moved toward the closed end of the substrate (71) until the drawer is completely closed. However, in the above-described prior art recovery buffer device (70), the tube forming the gas is formed on the substrate (71), so that the buffering effect of the gas M359248 is inconsistent or Due to the wear after prolonged use, it is not possible to replace the gas J1 rod when it is not required for the Beijing equipment. It can only be used continuously, or the entire set of recovery buffers can be replaced. In addition, since the end of the spring (72) is sandwiched between the two interlocking pieces (73), the spring (72) is subjected to its elastic restoring force after being used for a long time after being used for a long time. Affecting the end of the spring (72) will push the two interlocking pieces (73) to the top, causing the bonding force between the end of the spring (72) and the linking piece (73) to become weak, so that It is easy to disengage the spring (72) from the interlocking piece (73), which causes the prior art recovery buffer device (70) to lose its automatic reset effect; further, the sliding plate (71 3) of the substrate (71) is The combined area between the convex guiding portions (731) of the linking piece (73) is small, and the combination is unstable, which will cause the linking piece (73) to move. Instability. As described above, the prior art restoring cushioning device (70) for hanging furniture rails does have further improvements. [New content] In view of the above-mentioned shortcomings of the prior art, the present invention provides a recovery buffer device for an external furniture slide rail, which is designed to solve the prior art buffer device in which a pneumatic rod is integrally formed on the buffer device.

The drawer gently moves toward the closed end of the substrate (1〇) until the drawer is completely closed. In the above design, since the cushioning member (40) is detachably disposed on the substrate (10), when the cushioning member (4〇) is inconsistent in specification, or the piston is worn due to long-term use, When the buffering effect is not satisfactory, the buffering member (40) can be directly removed, and another suitable cushioning member (40) can be replaced; and the upper portion is mainly fixed by the extended end of the elastic member (50) (4) Block (3〇) ' does not affect the joint relationship between the linkage block (3Q) and the slider (2G); and, by the connection portion (31) of the linkage block (30) and the substrate (1 ()) The second chute (10): the large-area combination 'effectively achieves the purpose of stably moving the linkage block (30) and/or the slider (20) is firmly coupled.
