A press-activated guide rail rebound box

Abstract

This invention discloses a press-linked guide rail rebound box, including a stop block, a hook, a synchronous slide, and a synchronous rod. The synchronous slide has a moving resistance block extending into a guide channel. As the synchronous slide slides, the moving resistance block abuts against or separates from a fixed resistance block pre-formed in the guide channel. The fixed resistance block and the moving resistance block together divide the guide channel into a communicating inlet section and an outlet section. When in an abutting state, the moving resistance block blocks and restricts the hook at the junction of the inlet and outlet sections. When in a separated state, the moving resistance block avoids the hook at the junction of the inlet and outlet sections. The synchronous slide has a synchronous groove that coincides with the outlet section of the guide channel and allows the hook to move. The hook applies force to push against the inner wall of the synchronous groove to drive the synchronous slide relative to the box body.

Description

Technical Field

[0001] This invention relates to the technical field of guide rail rebound structures, and in particular to a guide rail rebound box with press-linkage. Background Technology

[0002] Currently, in widely used drawer slides or concealed slides, a rebound box is used to enable the slide to open by pressing and rebounding. In order to solve the problem that traditional rebound boxes (such as Chinese Patent CN 213282174 U, a slide rebounder) are "easily damaged by impact when forcibly pulled outwards", the applicant previously proposed the technical solution "CN2022109394963, a press-rebound slide rebound box". By cooperating between the reset block and the elastic key at the blocking section, the drawer slide can be opened even when forcibly pulled outwards, which protects the slide rebound box and effectively extends its durability and lifespan.

[0003] Secondly, in actual use, drawers are often equipped with two guide rails, each with one rebound box. In this case, the two rebound boxes do not have a synchronized linkage mechanism. If the user applies pressure to the center of the drawer panel, the two rebound boxes experience almost equal forces, resulting in synchronized locking or unlocking. However, if the user applies force to one side of the drawer panel, the forces experienced by the two rebound boxes will differ significantly.

[0004] Specifically, the rebound box adjacent to the point of force application receives greater force and can complete the unlocking and rebounding operation normally, while the rebound box far from the point of force application receives less force and is insufficient to complete the unlocking. As a result, one of the two rebound boxes is in an unlocked state while the other is still in a locked state, which ultimately causes the drawer and guide rail to be unable to open normally, requiring the user to press the button again, affecting the user experience. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a press-linked guide rail rebound box with synchronous linkage function, stable and reliable characteristics.

[0006] To achieve the above objectives, the present invention provides a press-linked guide rail rebound box, comprising a stop block elastically slidably disposed on the box body, and a hook member hinged to the stop block. The hook member moves along a pre-set guide channel on the box body. It also includes a synchronous slide block slidably fitted onto the box body and a synchronous rod hinged to the box body and driven by the synchronous slide block. The synchronous slide block is formed with a moving resistance block extending into the guide channel. As the synchronous slide block slides, the moving resistance block abuts against or... Separation and engagement: The fixed resistance block and the moving resistance block together divide the guide channel into a conductive inlet section and an outlet section, wherein the moving resistance block in the abutting state blocks and restricts the hook at the junction of the end of the inlet section and the outlet section; the moving resistance block in the separated state avoids the hook at the junction of the end of the inlet section and the outlet section; the synchronous slide is formed with a synchronous groove that coincides with the outlet section of the guide channel and allows the hook to move, wherein the hook applies force to push against the inner wall of the synchronous groove to drive the synchronous slide relative to the box body to slide.

[0007] Furthermore, the hook can engage with the inner wall of the rear end of the synchronization groove, thereby pushing the synchronization slide relative to the box body to slide backward.

[0008] Furthermore, when the synchronous slide block slides backward, the front end of the synchronous groove abuts against the constant resistance block to block and restrict the hook member from moving forward along the guide section, so that the hook member can contact and cooperate with the inner wall of the front end of the synchronous groove, thereby pushing the synchronous slide block forward relative to the box body.

[0009] Furthermore, the synchronous slide block is formed with a straight tooth section, and the end of the synchronous rod is provided with a linkage gear that meshes with the straight tooth section.

[0010] Furthermore, the abutting moving resistance block and the fixed resistance block form a groove at the rear end of the blocking hook component.

[0011] Furthermore, a clearance is formed between the phase-separated dynamic resistance block and the fixed resistance block, allowing the rear end of the hook to pass directly through.

[0012] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: 1) The locking function is achieved by blocking and restricting the pulling member through the abutting fixed resistance block and the moving resistance block; 2) The moving resistance block and the fixed resistance block are separated by the pressing action or the synchronous slide block, so that the pulling member can smoothly enter the guide section and achieve the unlocking function; 3) The synchronous linkage function between the two rebound boxes can be achieved by the synchronous slide block and the synchronous rod.

[0021] To facilitate understanding of the present invention, a more complete description is given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete.

[0022] See appendix Figure 1-6As shown, in this embodiment, a press-activated guide rail rebound box includes a box body 1, a stop block 2, a reset block 3, a hook 4, and a tension spring 21. The buffer self-closing function and structural principle between the rebound box and the guide rail 6 can be found in the applicant's previously filed patent "CN2022109394963, A Press-Activated Guide Rail Rebound Box". For ease of understanding, the basic functions and structure are explained below; other principles will not be elaborated further. Specifically, the stop block 2 is slidably mounted on the box body 1 in the front-back direction. A tension spring 21 is provided between the front end of the stop block 2 and the box body 1. The elastic force of the tension spring 21 allows the stop block 2 to slide forward relative to the box body 1 without restriction. The rear end of the stop block 2 is hinged to the hook 4, and the rear end of the hook 4 moves along a pre-set guide channel 5 on the box body 1. The reset block 3 is movably hinged to the front end of the stop block 2, allowing the reset block 3 to move synchronously back and forth with the stop block 2. The reset block 3 slides along the reset guide rail 6 pre-set on the housing 1. The reset guide rail 6 is divided into a clearance section and a blocking section along its front-to-back extension direction. The clearance section of the reset guide rail 6 has a clearance groove formed for the reset block 3 to slide into. Specifically, when the reset block 3 moves forward synchronously with the stop block 2, the reset block 3 moves forward along the reset guide rail 6 from the blocking section to the clearance section, and the reset block 3 slides down into the clearance groove, thus allowing the reset block 3 to slide down and clear the clearance. Conversely, when the reset block 3 moves backward synchronously with the stop block 2, the reset block 3 moves forward along the reset guide rail 6 from the clearance section to the blocking section, and the reset block 3 slides up into the blocking section, thus allowing the reset block 3 to slide up and block the clearance. A gap space is formed between the stop block 2 and the reset block 3 to accommodate the contact block 61 of the guide rail 6, so that the contact block 61 can abut against the stop block 2 and the reset block 3, thereby realizing the linkage between the contact block 61 and the rebound box in the open and closed states of the guide rail 6.

[0023] In this embodiment, see Appendix Figure 3 As shown, it also includes a synchronous slide block 7 that slides and fits on the box body 1 and a synchronous rod 8 that is hinged to the box body 1 and has a toothed transmission with the synchronous slide block 7. Specifically, the end of the synchronous slide block 7 is formed with a straight tooth portion 73, and the end of the synchronous rod 8 is provided with a linkage gear 81 that meshes with the straight tooth portion 73. In actual use, the two ends of the synchronous rod 8 act on the two rebound boxes respectively, and the rotation of the synchronous rod 8 enables the synchronous slide blocks 7 of the two rebound boxes to achieve synchronous linkage.

[0024] In this embodiment, the synchronous slide 7 is integrally formed with a moving resistance block 71 extending into the guide channel 5. The moving resistance block 71 moves synchronously with the synchronous slide 7 as the synchronous slide 7 slides relative to the housing 1. Furthermore, a fixed resistance block 51 is formed within the guide channel 5 of the housing 1. As the synchronous slide 7 slides, the moving resistance block 71 and the fixed resistance block 51 abut or separate. Specifically, when the synchronous slide 7 slides forward relative to the housing 1, the moving resistance block 71 abuts against the fixed resistance block 51; conversely, when the synchronous slide 7 slides backward relative to the housing 1, the moving resistance block 71 separates from the fixed resistance block 51.

[0025] Furthermore, the constant resistance block 51 and the moving resistance block 71 together divide the guide channel 5 into a connected inlet section 52 and an outlet section 53, so that the rear end of the hook member 4 can move along the inlet section 52 and the outlet section 53 respectively. Specifically, when the stop block 2 slides backward along the box body 1, the rear end of the hook member 4 moves along the inlet section 52; conversely, when the stop block 2 slides forward along the box body 1, the rear end of the hook member 4 moves along the outlet section 53.

[0026] In this embodiment, the moving resistance block 71, which is in an abutting state, blocks and restricts the hook member 4 at the junction of the end of the inlet section 52 and the outlet section 53. The abutting moving resistance block 71 and the fixed resistance block 51 form a groove that blocks the rear end of the hook member 4. That is, the rear end of the hook member slides forward into the groove from the inlet section 52, and conversely, the rear end of the hook member needs to move backward to slide out of the groove to the outlet section 53.

[0027] Specifically, when the stop block 2 is subjected to a backward external force and slides backward against the elastic force of the tension spring 21, the hook 4 moves backward along the guide section 52 until the stop block 2 slides backward to the designated position, and the hook 4 reaches the end of the guide section 52. At this time, the external force is removed, allowing the stop block 2 to slide forward under the elastic force of the tension spring 21, and the hook 4 moves forward and slides into the groove formed by the moving resistance block 71 and the fixed resistance block 51. The rear end of the hook 4 engages with the groove to restrict the forward sliding of the hook 4 and the stop block 2, thus locking the block. In the locked state, when the stop block 2 is subjected to a backward external force and slides backward, the hook 4 moves backward and slides out of the groove, unlocking the block. At this time, the external force is removed, allowing the stop block 2 to slide forward under the elastic force of the tension spring 21, and the hook 4 moves along the guide section 53, achieving a rebound opening effect.

[0028] Further details can be found in the appendix. Figure 4As shown, the moving resistance block 71 in a separated state avoids the hook piece 4 at the junction of the end of the inlet section 52 and the outlet section 53. That is, a clearance gap is formed between the separated moving resistance block 71 and the fixed resistance block 51, allowing the rear end of the hook piece 4 to pass directly through. This allows the hook piece 4 to slide forward under the elastic force of the tension spring 21, so that its rear end slides directly out to the outlet section 53 through the clearance gap, achieving the effect of rebound opening.

[0029] In this embodiment, the synchronous slide 7 is formed with a synchronous groove 72 that overlaps with the guide channel 5's outlet section 53 and allows the hook member 4 to move. Specifically, the rear end of the hook member 4 moves simultaneously along the area where the outlet section 53 overlaps with the synchronous groove 72. During the movement of the hook member 4 along the outlet section 53, the hook member 4 can abut against the inner wall of the synchronous groove 72. See attached diagram for details. Figure 5 As shown, in the locked state, the stop block 2 is subjected to an outward force, causing the hook 4 to move backward. This causes the rear end of the hook 4 to slide backward out of the slot and continuously contact the inner wall of the rear end of the synchronization groove 72. Consequently, the hook 4 exerts force to push the synchronization slide 7 backward relative to the housing 1, thus unlocking the mechanism. When the external force is removed, the stop block 2 slides forward under the elastic force of the tension spring 21, and the hook 4 moves along the guide section 53 and the synchronization groove 72, achieving a rebound opening effect.

[0030] Furthermore, during the backward movement of the synchronous slide 7 of the aforementioned rebound box, the synchronous slide 7 drives the synchronous rod 8 to rotate via the spur gear 73 and the linkage gear 81. The rotation of the synchronous rod 8 causes the synchronous slide 7 of the other rebound box connected to its other end to move backward in sync. This backward movement of the synchronous slide 7 of the other rebound box causes the moving resistance block 71 to separate from the fixed resistance block 51. After the external force is removed, the hook 4 of the other rebound box can slide directly out through the clearance to the guide section 53 and can move along the guide section 53 and the synchronous groove 72. Thus, through the linkage action of the synchronous rod 8, the synchronous linkage and rebound opening effect of the two rebound boxes is achieved.

[0031] See appendix Figure 6As shown, in this embodiment, when the synchronous slide 7 is in the rearward state, the front end of the synchronous groove 72 abuts against the constant resistance block 51 to block and restrict the hook 4 from moving forward along the guide section 53, so that the pull member can contact the inner wall of the front end of the synchronous groove 72. Thus, during the rebound opening period, the rear end of the hook 4 moves forward along the guide section 53 and continuously contacts the inner wall of the front end of the synchronous groove 72, thereby the hook 4 applies force to push the synchronous slide 7 forward relative to the box 1, realizing the reset of the synchronous slide 7 (at this time, the synchronous slide 7 of the other rebound box moves forward to reset by means of the rotation linkage of the synchronous slide 7); after the synchronous slide 7 is completely reset, the hook 4 disengages from the synchronous groove 72 and continues to rebound open along the guide section, thus realizing the linkage reset effect of the synchronous slides 7 of the two rebound boxes.

[0032] In summary, for ease of understanding, the following explanations are provided in conjunction with specific practical application scenarios. See appendix. Figure 7 As shown, in actual use, two guide rails 6 are configured on each side of a drawer, and a rebound box is set on each guide rail 6. The two rebound boxes are linked together by a synchronous rod 8.

[0033] When the user closes the drawer, the two guide rails 6 gradually close, so that the contact blocks 61 of the two guide rails 6 act on the two rebound boxes respectively, thereby synchronously pushing the stop blocks 2 of the two rebound boxes to move backward, and then causing the pull member to move backward along the guide section 52 until the guide rails 6 are completely closed. When the user releases the external force, the rear ends of the pull members of the two rebound boxes slide forward into the slots formed by the moving resistance block 71 and the fixed resistance block 51 under the elastic force of the tension spring 21, thus realizing the locking function.

[0034] When the user presses the center of the drawer, the force on both sides of the drawer is almost equal, causing the stop blocks 61 of the two guide rails 6 to push the stop blocks 2 backward in sync. This causes the pull members of the two rebound boxes to move backward in sync, exiting their respective slots and sliding into the guide section 53, thus unlocking the drawer. The user then releases the pressure, and the elasticity of the tension spring 21 causes the stop blocks 2 to slide forward, which in turn causes the pull members to move forward along the guide section 53. (At this point, the stop blocks 2 touch the stop blocks 61 and move forward in sync until the reset block 3 slides into the clearance groove, allowing the stop blocks 61 to jump over the reset block 3 without obstruction, and the drawer guide rails 6 to rebound and open due to inertia.)

[0035] When the user presses the drawer to one side, the force on both sides of the drawer is uneven. The side with greater force becomes the active side, and the side with less force becomes the passive side (the force on the passive side is insufficient to move the pull member backward out of the slot). The pull member of the rebound box on the active side moves backward out of the slot and slides into the guide section 53, pushing the synchronous slide block 7 backward. Then, with the help of the rotational linkage of the synchronous rod 8, the synchronous slide block 7 of the rebound box on the passive side moves backward, causing the moving resistance block 71 on the passive side to separate from the fixed resistance block 51, thus avoiding the pull member. The pull member on the passive side then slides into the guide section 53 under the elastic force. Afterward, the user releases the pressure, and the elastic force of the tension spring 21 drives the stops 2 on both the passive and active sides to slide forward synchronously. This causes the pull members on the passive and active sides to move forward along their respective guide sections 53, achieving synchronous rebound opening of the two rebound boxes.

[0036] The aforementioned rebound box's locking and unlocking rebound functions are stable, reliable, easy to operate, and synchronized, greatly enhancing the user experience.
