[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] According to the attached Figures 1 to 9 As shown, the anti-failure slide rail push-out mechanism of the present invention comprises an upper rail 1, a middle rail 2 and a lower rail 3 which are slidably connected in sequence. The lower rail 3 can be detachably provided with a push-out device, and the upper rail 1 is provided with a toggle block 4 which is engaged or separated with the push-out device as it is opened and closed, and the push-out device comprises a rebound shell 5, a rebound tension spring 6, a sliding block 7 and a rotating member 8. Among them, the rebound shell 5 is installed on the outer side of the lower rail 3, and the two elastic ends of the rebound tension spring 6 are respectively buckled on the rebound shell 5 and the sliding block 7, and the rotating member 8 is installed on the sliding block 7 and slidably connected with the sliding block 7 on the rebound shell 5, and the sliding block 7 is axially connected with a rebound hook 9. The rebound shell 5 is provided with a directional motion track groove 10, and the rebound shell 5 is provided with an anti-failure intervention component 11 for the rebound hook 9 to slide in a directional manner on the directional motion track groove 10 so that the sliding block 7 can achieve directional sliding energy storage, rebound locking and press-to-reset unlocking under the elastic action of the rebound tension spring 6. The anti-failure intervention component 11 includes a magnet 111 magnetically adsorbed and connected to the rebound hook 9, and the magnet 111 is installed on one side of the directional motion track groove 10.

[0040] In practical applications, the directional motion track slot 10 includes an energy storage guide slot 101, a rebound locking hook 102, and a push-reset unlocking slot 103. The energy storage guide slot 101, the rebound locking hook 102, and the push-reset unlocking slot 103 are connected end to end in sequence and form a Y-shaped directional motion track slot 10 for the rebound hook 9 to slide, and the magnet 111 is arranged on one side of the entrance end of the energy storage guide slot 101.

[0041] When the slide rail is closed, the upper rail 1 of the slide rail moves to a specific position, and at the same time, the toggle block 4 is buckled on the rotating member 8 and pushes the sliding block 7 to move. During this period, the rebound hook 9 moves with the sliding block 7. When the rebound hook 9 reaches the entrance end of the energy storage guide slot 101, the rebound hook 9 swings under the intervention of the magnetic attraction of the magnet 111 and slides into the energy storage guide slot 101, realizing the push-to-pop mechanism to press and store energy. When the rebound hook 9 reaches the end of the energy storage guide slot 101, the sliding block 7 moves forward to the rebound locking hook position 102 under the elastic reset force of the rebound tension spring 6, realizing the locking and energy storage of the push-to-pop mechanism.

[0042] When the slide rail is opened, the drawer is pressed inward to push the upper rail 1 of the slide rail, so that the rebound hook 9 escapes from the rebound locking hook position 102, and the push-pull mechanism is unlocked. Subsequently, under the elastic reset force of the rebound tension spring 6, the rebound hook 9 moves forward along the press-reset unlocking slot 103, causing the rotating member 8 to separate from the toggle block 4, and the slide rail is fully opened.

[0043] In this way, under the magnetic adsorption intervention of the magnet 111, the rebound hook 9 moves along the directional motion trajectory groove 10 according to the specified motion trajectory, realizing the closing and energy storage of the push-to-pop mechanism, rebound locking, and pressing to unlock and open, with stable operation, avoiding reverse entry into the directional motion trajectory groove 10, which would cause the push-to-pop mechanism to fail, and ensuring the normal movement of the slide rail.

[0044] Reference Figures 1 to 9 As shown, in further detail, the rebound housing 5 is provided with a mounting groove 51 , and the mounting groove 51 is provided on a side close to the entrance end of the directional motion trajectory groove 10 , and the magnet 111 can be disassembled and assembled in the mounting groove 51 .

[0045] Through the structure of the magnet 111 and the mounting groove 51, the magnet 111 is firmly mounted on the rebound housing 5, thereby enhancing the structural stability, ensuring the magnetic adsorption intervention effect, and ensuring the normal use of the product.

[0046] In addition, the sliding block 7 is provided with a connecting shaft 71 that passes through the rotating member 8 and is slidably connected to the rebound shell 5. The swinging end of the rotating member 8 is provided with a swinging shaft 81 that swings relatively around the connecting shaft 71. The inner side of the rebound shell 5 is provided with a guide groove 53 for the sliding movement of the connecting shaft 71 and the swinging shaft 81. The rebound shell 5 is provided with an open guide protrusion 52 that is slidably connected to the rotating member 8 and rotates simultaneously to engage or separate with the toggle block 4.

[0047] The structural coordination of the sliding block 7, the rotating member 8 and the rebound housing 5 improves the structural stability, enables the pushing device to be smoothly engaged or separated from the upper rail 1, and improves the running smoothness.

[0048] At the same time, the rear end of the guide slide groove 53 is provided with a mounting groove 55 for facilitating the rotation member 8 to slide into or out of the rebound housing 5, and the mounting groove 55 is communicated with the guide slide groove 53, and the rotation member 8 is slidably mounted on the guide slide groove 53 through the mounting groove 55. The structure is simple, the assembly is convenient, and the normal opening and closing of the slide rail is ensured.

[0049] Furthermore, the front end of the sliding block 7 is buckled with a rebound soft rubber 12 for elastic connection with the rebound housing 5, and the rear end shaft of the sliding block 7 is connected with a rebound hook 9.

[0050] Under the action of the rebound soft rubber 12, the sliding block 7 is prevented from colliding with the rebound shell 5 due to the rebound action of the rebound tension spring 6 when the push is opened, thereby protecting the push-open mechanism and improving the user experience.

[0051] Another option, see Figures 10 to 15 As shown, an anti-failure slide rail push-out mechanism comprises an upper rail 1, a middle rail 2 and a lower rail 3 which are slidably connected in sequence. The lower rail 3 can be detachably provided with a press-rebound device, the upper rail 1 is provided with a toggle block 4 which is engaged or separated with the press-rebound device as it is opened and closed, and the press-rebound device comprises a rebound housing 5, a rebound tension spring 6, a sliding block 7 and a rotating member 8. The rebound housing 5 is installed on the outer side of the lower rail 3, the two elastic ends of the rebound tension spring 6 are respectively buckled on the rebound housing 5 and the sliding block 7, the rotating member 8 is installed on the sliding block 7 and is slidably connected with the sliding block 7 on the rebound housing 5, and the sliding block 7 is axially connected with a rebound hook 9. The rebound shell 5 is provided with a directional motion track groove 10, and the rebound shell 5 is provided with an anti-failure intervention component 11 for the rebound hook 9 to slide in a directional manner on the directional motion track groove 10 so that the sliding block 7 can achieve directional sliding energy storage, rebound locking and press-to-reset unlocking under the elastic action of the rebound tension spring 6. The anti-failure intervention component 11 includes a boss 112 frictionally connected to the rebound hook 9, and the boss 112 is arranged on one side of the directional motion track groove 10.

[0052] In practical applications, the boss 112 is arranged on one side close to the output end of the directional motion trajectory groove 10, and the boss 112 is arranged to be an inclined boss 112 integrally formed with the rebound housing 5 and gradually inclined upward along the energy storage direction of the sliding block 7.

[0053] Moreover, the directional motion track groove 10 includes an energy storage guide groove 101, a rebound locking hook 102, and a press-reset unlocking groove 103. The energy storage guide groove 101, the rebound locking hook 102, and the press-reset unlocking groove 103 are connected end to end in sequence and form a Y-shaped directional motion track groove 10 for the rebound hook 9 to slide, and the boss 112 is arranged on one side of the output end of the press-reset unlocking groove 103.

[0054] When the slide rail is closed, the upper rail 1 of the slide rail moves to a specific position, and at the same time, the toggle block 4 is buckled on the rotating member 8 and pushes the sliding block 7 to move. During this period, the rebound hook 9 moves with the sliding block 7. When the rebound hook 9 reaches the entry end of the energy storage guide slot 101, since the boss 112 is on the side of the output end of the directional motion track slot 10, the friction resistance on one side of the output end of the directional motion track slot 10 is increased, prompting the rebound hook 9 to swing toward the input end of the directional motion track slot 10 under the intervention of the friction resistance of the boss 112 and slide into the energy storage guide slot 101, so that the push-to-pop mechanism presses and stores energy. When the rebound hook 9 reaches the end of the energy storage guide slot 101, the sliding block 7 moves forward to the rebound locking hook position 102 under the elastic reset force of the rebound tension spring 6, so that the push-to-pop mechanism is locked and stored energy.

[0055] When the slide rail is opened, press inwards on the drawer to push the upper rail 1 of the slide rail, so that the rebound hook 9 escapes from the rebound locking hook position 102, and the push-pull mechanism is unlocked. Subsequently, under the elastic reset force of the rebound tension spring 6, the rebound hook 9 moves forward along the push-reset unlocking slot 103. During this period, since the boss 112 is set as an inclined boss 112 integrally formed with the rebound housing 5 and gradually tilted upward along the energy storage direction of the sliding block 7, the connection friction resistance between the rebound pendant and the boss is gradually reduced, ensuring that the rebound pendant flows smoothly from the push-reset unlocking slot 103, so that the rotating member 8 is separated from the toggle block 4, and the slide rail is fully opened.

[0056] Under the intervention of the friction resistance of the boss 112, the rebound hook 9 moves along the directional motion trajectory groove 10 according to the specified motion trajectory, so that the push-to-pop mechanism closes and stores energy, rebounds to lock, and is unlocked and opened by pressing. The operation is stable, and reverse entry into the directional motion trajectory groove 10 is avoided, which causes the push-to-pop mechanism to fail, thereby ensuring the normal movement of the slide rail.

[0057] Reference Figures 10 to 15 As shown, in further detail, the sliding block 7 is provided with a connecting shaft 71 that passes through the rotating member 8 and is slidably connected to the rebound housing 5, the swinging end of the rotating member 8 is provided with a swinging shaft 81 that swings relatively around the connecting shaft 71, the inner side of the rebound housing 5 is provided with a guide groove 53 for the sliding movement of the connecting shaft 71 and the swinging shaft 81, and the rebound housing 5 is provided with an open guide protrusion 52 that is slidably connected to the rotating member 8 and rotates simultaneously to engage or separate with the toggle block 4.

[0058] The structural coordination of the sliding block 7, the rotating member 8 and the rebound housing 5 improves the structural stability, enables the pushing device to be smoothly engaged or separated from the upper rail 1, and improves the running smoothness.

[0059] Meanwhile, the rear end of the guiding sliding groove 53 is provided with an installation through groove 55 for facilitating the sliding of the rotating member 8 into or out of the rebounding housing 5. The installation through groove 55 is communicated with the guiding sliding groove 53, and the rotating member 8 is slidably mounted on the guiding sliding groove 53 through the installation through groove 55. The structure is simple and the assembly is convenient, ensuring the normal opening and closing of the slide rail.

[0060] In addition, a rebounding soft rubber 12 elastically connected to the rebounding housing 5 is buckled at the front end of the sliding block 7, and a rebounding hook 9 is axially connected to the rear end of the sliding block 7.

[0061] Under the action of the rebounding soft rubber 12, when pressing to open, it can avoid the sliding block 7 colliding with the rebounding housing 5 due to the excessive rebounding action of the rebounding spring 6, generating noise, protecting the bullet pushing mechanism and improving the use experience.

[0062] The third solution, referring to Figures 16 to 20 As shown, different from the first solution and the second solution: the anti-failure intervention component 11 includes a magnet 111 magnetically adsorbed and connected to the rebounding hook 9 and a convex platform 112 frictionally connected to the rebounding hook 9. The magnet 111 is installed on one side of the directional movement track groove 10, and the convex platform 112 is arranged on one side of the directional movement track groove 10.

[0063] By using the adsorption and intervention effect of the magnet 111 of the anti-failure intervention component 11 and the frictional resistance intervention effect of the convex platform 112, the rebounding hook 9 can smoothly move along the specified track of the directional movement track groove 10, avoiding the failure of the pressing anti-lock mechanism, improving the structural stability and reliability, and ensuring the normal use of the slide rail.

[0064] The above specific embodiments are only the specific embodiments with better effects of the present invention. Any structure identical or equivalent to the duplex stainless steel frame bar for photovoltaic frame and the photovoltaic frame using the duplex stainless steel frame bar of the present invention is within the protection scope of the present invention.
