The specific embodiment
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is a kind of drawer type chamber door guide rail with auto-lock function, and it comprises outer guide 1, middle guide rail 3 and interior guide rail 5, and the back side of described outer guide 1 offers installing hole, so that fixing.Between described outer guide 1 and the middle guide rail 3 guiding rail 2 is installed, between middle guide rail 3 and interior guide rail 5 moving guide rail 4 is installed, by the setting of guiding rail 2 and moving guide rail 4, middle guide rail 3 and interior guide rail 5 can be pulled out forward in classification.
The rear end of described outer guide 1 is provided with horizontal chute 1.1, the front end of this chute 1.1 is provided with the stopper slot 1.2 of downward bending, activity is covered slide plate 7 is housed on chute 1.1, be provided with extension spring 6 between the rear end of outer guide 1 and the slide plate 7, under without other External Force Actings, extension spring 6 can make slide plate 7 automatically reset backward.Described extension spring 6 is provided with two, lays respectively at upside and the downside of chute 1.1, makes slide plate 7 upper and lower stressed even.Offer longitudinal hole 7.1 at slide plate 7, the guiding traveller 10 that is movably installed in the chute 1.1 is interspersed in the longitudinal hole 7.1, so slide plate 7 can move forward and backward along chute 1.1 with guiding traveller 10.The equal in length of the length of described longitudinal hole 7.1 and stopper slot 1.2 makes guiding traveller 10 can slip into stopper slot 1.2.In guiding traveller 10 embedding stopper slots 1.2, guiding traveller 10 just can't move forward and backward, and slide plate 7 also can't move forward and backward simultaneously.The rear end of described interior guide rail 5 is provided with and promotes draw-in groove 5.1, and the front end of this promotion draw-in groove 5.1 is inclined upwardly and is bent to form skewed slot 5.2, and the rear end that promotes draw-in groove 5.1 is opening 5.3, and described guiding traveller 10 can activity be interspersed in promotion draw-in groove 5.1.When interior guide rail 5 was positioned at rearmost end, guiding traveller 10 was positioned at the top of skewed slot 5.2.When interior guide rail 5 moved forward, skewed slot 5.2 meeting promotion guiding travellers 10 prolonged chute 1.1 and move forward, and slide plate 7 also moves forward together simultaneously.Guiding traveller 10 arrive chutes 1.1 foremost the time, the skewed slot 5.2 downward thrust of traveller 10 that leads makes guiding traveller 10 slip into stopper slot 1.2, this moment, slide plate 5 can't move forward again.When interior guide rail 5 moves backward, guiding traveller 10 enters from the opening 5.3 that promotes draw-in groove 5.1, after guiding traveller 10 arrives skewed slot 5.2, skewed slot 5.2 can be with guiding traveller 10 from stopper slot 1.2 interior releases, this moment is because the restoring force of extension spring 6, can drive slide plate 7, middle guide rail 3 and together backward indentation of interior guide rail 5, make the chamber door automatic pick.The open outer side of described promotion draw-in groove 5.1 is large, inboard little, enters with convenient guiding traveller 10.Utilize the autoshutdown of the pulling force realization chamber door of extension spring 6, the assurance chamber door is fastened automatically, is not easy outwards to skid off, and a process of tension is arranged when closing chamber door, and feel is pure.
The upper and lower two sides of described guiding rail 2 all are embedded with many to little ball 8, and the utility model has respectively been installed seven pairs of little balls 8 in the upper and lower both sides of guiding rail 2.Be embedded with equally manyly to large ball 9 in the upper and lower both sides of moving guide rail 4, the utility model has respectively been installed ten pairs of large balls 9 in the upper and lower both sides of moving guide rail 4, and this large ball 9 offsets with the medial surface of middle guide rail 3.The setting of ball makes the movement of middle guide rail 3, interior guide rail 5 more flexible, and sound is also lighter, is supported by ball, improve the bearing capacity of guide rail, and ball is very wear-resisting, improves the service life of guide rail.
Such as Fig. 4, shown in Figure 5, described interior guide rail 5 rear ends are provided with suspension hook 12, the front end of this suspension hook 12 opens, upside at suspension hook 12 is provided with step 12.1, and the front end of described middle guide rail 3 is provided with fixture block 11, when interior guide rail 5 moves forward, suspension hook 12 can embed in the fixture block 11, and the step on the suspension hook 12 12.1 interlocks with the rear end face of fixture block 11, deviates to prevent interior guide rail 5, forms self-locking device.Finger is downward one group of suspension hook 12 gently, just can make suspension hook 12 front ends open the place and merge, and this moment, step 12.1 also can pass through fixture block 11, interior guide rail 5 can be taken out.Because interior guide rail 5 all is fixing with the back side of chamber door, therefore interior guide rail 5 can shirk and just be equivalent to and chamber door can be shirked.The front end of the 11 pairs of moving guide rails 4 of fixture block on the described middle guide rail 3 is spacing, is provided with the rear end limited block of self limited block and moving guide rail 4 in the rear end of middle guide rail 3, effectively prevents firmly excessively, makes chamber door skid off the situation of casing.This guide rail is with a kind of self-locking device, and when the user did not want to pull out chamber door, how firmly chamber door can not break away from from casing again, and the big box door that effectively prevents from exert oneself skids off the situation of casing, fool proof reliably.When the user wants to pull out chamber door, when allowing chamber door break away from casing, only need downward one group gently on the finger of suspension hook 12 usefulness on the interior guide rail 5, make suspension hook 12 front ends open the place and merge, suspension hook 12 just can break away from fixture block immediately, removes self-locking state, and release is very convenient.
