New description: • [New technical field] ‘This creation relates to a rail device, especially a three-section sliding device with a simple fixing and unlocking mechanism. [Prior Art] Slipper is generally applied to a device capable of carrying articles for relatively moving/moving two objects, and is initially used in furniture such as drawers, computer keyboard trays, etc., and later used in electronic devices such as servers. _ Three-section slipper usually includes - external, one middle and one inner. The above two are lightly coupled to each other, and the inner rail and the middle handle can slide back and forth relative to the outer handle in the same axis direction. This three-section slip often requires a snap-on structure to maintain the slide rail in this position when it is pulled out to the full position. For example, the sliding structure of the sliding type is provided by the first lip holder for the second hand to move into the movement. The first end has a stop block, and the first one has a card on the side of the card. The end is formed by a small slanted shoulder, and the lower end of the other side forms a locking portion; the second rail is provided with a stop block and the first stop block T is connected with the other end, and the other end is combined with a latching block. The first contact with the first rail is provided with a clamping body having two elastically closed clamping legs, and the two clamping members are respectively connected with the cool body by the middle portion, and the two ends of the two clamping legs are respectively protruded from the body. One of the two clamping legs has a small spacing at the end, and can be snapped into the cartridge portion of the clamping block to form a locking function, and a third holding can be set in the second rail, and the third rail is provided with a locking member. The second card card block is abutted. When the sliding operation is performed, the sliding structure can be engaged by the fastening structure, and when the sliding rail is retracted, the card is provided with appropriate clamping force to prevent the sliding rail from being unintentionally retracted. However, the γ哕2 M323840 rail has a complicated structure and is costly to manufacture. [New content] In view of the above, it is necessary to provide a sliding device with a simple locking and unlocking structure. A sliding device includes a first sliding handle, a second sliding rail and a third sliding rail. The second sliding sliding member is slidably mounted on the first sliding rail, and the third sliding rail (7) is mounted on the first sliding rail. On the first sliding handle, a convex portion having a beveled surface is disposed on the inner side of the first sliding handle, and a receiving groove is formed on the sliding handle of the far-seat, the underwear α is a gravity pin, and the third sliding inner side is installed. Having an unlocking member, when the first sliding handle extends outward from the first sliding handle to a locking position, one end of the gravity pin passes over the convex portion along the inclined surface of the convex portion of the first sliding handle When the gravity moves back to the bottom of the receiving groove to lock the protrusion of the first sliding handle # ' ^ the second sliding rail retracts inward from the second sliding, the other end of the gravity lock The unlocking element is lifted to avoid the position of the raised portion so that the 4th slide rail can be freely retracted from the clamped position within the first slide. Compared with the prior art, the creative device drives the gravity pin to move upward along the receiving slot when the second sliding stretch is extended by the convex portion disposed on the inner side of the first sliding handle, and when the gravity pin is over the (four) raised tribe When the bottom of the pocket is at the bottom of the pocket, the second sliding latch is locked. When the third sliding slip is returned to the second sliding rail, the unlocking member holds the gravity lock to prevent the second sliding rail from avoiding the locking function of the protruding portion. And can slide back to the first slip (four). The structure of the slide rail device is simple [embodiment] ', please refer to FIG. 1. The preferred embodiment of the present slide device includes a M323840 first slide rail 10, a second slide rail, a stack-t 4 inch, and Unlock section 50. 2nd slide rail 3G, - gravity pin fold open / Γ 2 off 2, the first slide rail 1G upper and lower edges respectively bend the second slide 2G slide rail 12, the first slide rail 10 = inwardly convex a pair of axially symmetric projections 14, each of which includes a guiding slanting surface 141, the first sliding rail ig being convexly inwardly at its front & and the rear end of the raised portion 14 - Position block 16. The upper and lower edges of the second sliding rail 20 are also respectively bent to form an obstruction 22 for the three materials 30, and the second sliding block 2 is provided with a clamping block 24 in the front end, and the movable device is arranged. A longitudinal receiving groove of the gravity pin 4 and a laterally punched clamping piece 28 are provided. The positioning block 24 and the clamping piece 28 are respectively protruded from the second sliding rail 2〇. The maximum inclination height of the convex portion 14 of the first sliding handle is less than - half of the longitudinal length of the storage sample % of the second sliding handle 2 (). The height of the card tab 28 is approximately equal to one-half of the longitudinal length of the slot. The upper and lower edges of the third sliding handle are respectively bent to form a sliding wall 32 slidable in the first sliding handle 20, and the front end of the third sliding handle 3 is vertically inwardly punched. The clamping piece 34 and the pair of mounting posts 36 are engaged at the rear end of the positioning block 24 of the second sliding handle 2 . The gravity pin 40 is formed by a pair of pin members. The center of the gravity pin 4 is movably mounted in the receiving groove 26 of the second sliding handle 20, and the two ends are respectively protruded from the two sides of the receiving groove 26. The unlocking member 50 includes a body 52 of substantially isosceles trapezoidal shape and a pair of inclined supporting faces 54 formed by vertically bending the two waists of the body 52. The body 52 corresponds to the installation of the third sliding handle 30. The post 36 defines a pair of mounting holes. 56. After the mounting posts 36 of the third sliding handle 30 respectively extend into the mounting holes 56 of the unlocking member 50_, the unlocking member 50 can be mounted inside the third sliding handle 30. The maximum height of the inclined supporting surface 54 of the unlocking member 50 is not lower than the maximum height of the inclined surface 141 of the convex portion 14 of the first sliding rail 10. Referring to FIG. 1 to FIG. 4 , the second sliding handle 20 is slidably mounted on the inner side of the first sliding rail 10 from the rail 12 of the first sliding handle 10 , and the third sliding handle 30 is mounted on the first sliding rail 10 . The sliding wall 32 of the second sliding rail 20 is slidably mounted on the inner side of the second sliding rail 20. When the second sliding handle 20 is extended rearward from the first sliding handle 10, the gravity pin 40 on the second sliding rail 20 gradually approaches the convex portion 14 on the inner side of the first sliding rail 10 and from the convex portion 14 The inclined surface 141 is moved upward until one end of the gravity pin 40 completely passes over the inclined surface 141 of the convex portion 14 , and the gravity pin 40 falls back to the bottom end of the receiving groove 26 by gravity and abuts against the convex portion 14 . The tail portion is configured to restrict the second slide rail 20 from slipping forward. At this time, the end φ end of the latching tab 28 of the second slide rail 20 abuts against the front end of the positioning block 16 adjacent to the boss portion 14 to limit The second slip 20 continues to extend rearwardly, so that the second slide 20 extends to the inside of the first slide 10 when it is extended to the position. If the second sliding handle 20 is to be slid back from the locking position to the first sliding handle 10, the third sliding handle 30 must first be extended backward from the second sliding handle 20 to ensure the third sliding portion 30. The unlocking member 50 on the inner side of the sliding handle 30 is located at the rear end of the gravity pin 40. At this time, the third sliding handle 30 is slid forward along the road 22 of the second sliding rail 20 until the other end of the gravity pin 40 slides. Up on the inclined supporting surface 54 of the lower end of the unlocking member 50, the gravity pin 40 is lifted by the inclined supporting surface 54 of the unlocking member 50 to the receiving slot when the second sliding rail 30 of the second sliding rail 30 slides forward horizontally. The middle portion of 26 avoids the raised portion 14 of the first sliding handle, and at this time, the second sliding handle 20 can be freely retracted into the first sliding handle 10. In summary, the creation department meets the requirements for new patent applications, and Mai filed a patent application. m is only for the best of the best.
