This creation is about a drawer slide with an automatic return device, especially a drawer slide with a stable structure and a good automatic positioning effect. [Previous technology]: In order to keep the drawers firmly closed, an automatic homing device with springs will be installed on the slide rails, which can provide automatic returning capabilities to pull back and close to a fixed point. However, the automatic homing device i currently sees has a variety of component forms. The cost is high and the furniture price of the safety drawer is increased. Therefore, the automatic homing device used by H f is mostly stable and not stable. Under the circumstances, it is easy to cause distortion of the automatic returning device, but instead cause the jam and failure of the drawer slide. [New content] In view of the problems existing in the design of the automatic homing device installed in the drawer described above, the creator has developed an automatic homing device: a waste extraction slide rail, which can mainly achieve a stable fixed position and provide rapid and effective pulling. Back to the drawer to achieve the purpose of automatic return. In order to achieve the aforementioned creative purpose, the technical means used in this creation is to provide a drawer slide rail with an automatic return device, which includes: ', a drawer slide rail with an automatic return device, its structure It includes a set of corresponding inner and outer rails; a push block formed on the outer or inner rail; a corresponding push block to be installed on the inner or outer rail; a certain M251524 has-front, -Back, top edge, bottom & first end and an opposite second end, a spring is formed on the front surface of the base near the bottom edge of the first end. A slider groove communicating with the elastic groove is formed in the slider groove. A longitudinal perforation penetrating the base is formed inside the slider groove, and a positioning groove communicating with the slider groove is formed on the bottom edge next to the second end of the base. A positioning slot is further formed in the positioning slot; a slider provided in the sliding slot is provided with a front surface, a rear surface, a top end, a bottom end, a first end, and a second end opposite to the _, Behind the top of the slider, corresponding to the longitudinal perforation extending through the base An extension is protruded, and a limiting opening is formed on the top surface of the extension for accommodating the pushing block. On the second end of the rear surface of the bottom of the slider, a position corresponding to the spring groove is formed-a spring post. A block is formed at the bottom end of the block near the first end, and the block can be operatively matched with a slot on the base; and a spring retractably disposed in a spring slot, the elastic base It has a fixed end and a free end. The fixed end in the middle is connected to the first end of the base, and the free end is connected to the elastic post of the slider. Preferably, a convex convex edge is formed on the inner wall of the base slider groove near the spring groove. Preferably, wherein the base is formed with a protruding post on the front near the first end and on the second end respectively; and two coupling holes are formed at positions opposite to the inner rail, and the protruding posts are snap-fitted. A constricted neck is formed on the fixed end of Che Huangjia's bullet yellow, and a pair of cool-holding cones are formed on the inner wall of the base shell tile to secure the inner part of the bullet; A hook is formed on the free end to catch the spring post on the slider. It is preferably formed on the upper side formed on the upper side formed on the upper side formed on the upper side and formed on the upper side to form a better plane column to prevent the ground, wherein the top end of the slider extends Qiu τ ° 丨 away from the first end inclined surface of the spring groove; The top of Shenbei Xi_, which is relatively close to the second end of the spring groove, is higher than the sloping surface of Qiu Wu '. Among them, the laterally perforated side wall of the center of the swell is aligned with the occlusion to prevent the slider from coming out. Also-the top end of the extension of the middle / lunar block is far from the first end of the spring groove. The top end of the inclined surface 'is relatively close to the second end of the spring groove. P ′, wherein the side wall of the central part of the bulge is longitudinally perforated with the side wall to prevent the slider from coming out. The ground 'is formed on the side of the slider facing the spring groove on the slider; and the spring bolt is formed on the opposite side of the elastic yellow surface to limit the withdrawal of the spring hook portion. The restriction of the yellow groove and the slider groove on the base allows the slider and the bullet to be moved by a stable traction, avoiding the distortion and deformation of the self-position device, causing damage to the extension slide rail, and cooperating with a variety of different Positioning components, such as spring 1 bolts, limiting posts, accommodating slots, positioning slots, etc., can be connected to each other. It is more solid, which makes the use of drawer slides with automatic return device better. [Embodiment] A drawer slide with an automatic returning device of the present invention includes: a set of inner and outer rails that are opposite to each other; a pushing block formed on the outer rail or an inner rail; Internal rail or externally-held base, a spring groove is formed on the side of the end of the base, and a slider groove communicating with the 7 M251524 spring groove is formed at the front end of the base. A longitudinal perforation is formed at the bottom of the slider groove. A positioning groove communicating with the slider groove is formed on the front side of the base at the same side as the spring groove, and a snap groove is formed at the bottom of the positioning groove; a slider is slidably arranged in the slider groove, and the top of the bottom surface of the slider Corresponding to the direction i extending toward the pushing block, there is an extension passing through the longitudinal penetration 1; or a limit opening is formed on the top surface of the extending portion for receiving the pushing block, and the bottom end of the bottom surface of the slider is determined by the spring groove. A spring post is formed at a position to fix a free end of the spring, and a ^ block is formed at a position where the bottom end of the bottom surface of the slider is relatively far from the spring post. ,
當滑執之内外執相對拉開移動時，推動塊藉由與縱向 穿槽的結合拉動滑塊滑移，直到滑塊到達定位槽並掉落於 定位槽之中’此時，滑塊產生偏移使推動塊脫出限止口的 限制以向前繼續移動，而當滑軌之内外執相對收合移動時 ，推動塊推向限止口並將滑塊導正，讓滑塊受到彈菁的拉 動，而自動回復定位。When the inside and outside of the slider are moved relatively apart, the push block slides through the combination of the longitudinal slot and the slider until the slider reaches the positioning slot and falls into the positioning slot. 'At this time, the slider is biased. Move the push block out of the limit stop to continue moving forward, and when the inside and outside of the slide rail are moved relative to the contraction, the push block is pushed to the limit stop and the slider is straightened, so that the slider is pulled by the bullet , And automatically respond to positioning.
