Technical Field

[0001] This utility model relates to the field of archive storage equipment technology, specifically an adjustable archive rack anti-tipping reinforcement device. Background Technology

[0002] Adjustable filing racks, as a type of high-efficiency, space-saving, dense storage device, are widely used in archives, libraries, and enterprise and institutional data rooms. They move forward and backward via sliding rails, effectively saving aisle space and increasing storage capacity per unit area.

[0003] As the amount of archives increases, the weight that existing adjustable filing racks can bear increases. During frequent pushing and pulling operations, the rack is prone to tilting or even falling over due to uneven force or inertia. This can not only cause structural deformation and damage to the guide rails, but also seriously threaten the personal safety of the operators.

[0004] Therefore, this utility model provides an adjustable file rack anti-tipping reinforcement device to solve the above problems. Utility Model Content

[0005] This utility model provides an adjustable file rack anti-tipping reinforcement device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable file rack anti-tipping reinforcement device, comprising a base plate and several file racks connected to the top of the base plate via a pulley structure, wherein guide rods are provided on both sides of the file racks, and both ends of the guide rods are connected to the top of the base plate via connecting frames, and the surface of the guide rods is slidably provided with an anti-tipping structure that cooperates with the side wall of the file rack; The base plate is provided with protective frames on both sides of the top. The inner side wall of the protective frame is bolted to a toothed plate. A movable plate is provided on one side of the toothed plate. The top of one side of the movable plate is provided with an upper inclined surface that cooperates with the toothed plate. The bottom of the other side of the movable plate is provided with a lower inclined surface that cooperates with the toothed plate. A U-shaped plate is provided on one side of the movable plate. The side wall of the movable plate is provided with an elastic connection structure that cooperates with the U-shaped plate. One side of the U-shaped plate is provided with a vertical plate that connects to the side wall of the anti-tipping structure, and one side of the vertical plate is provided with a vertical adjustment structure that cooperates with the U-shaped plate.

[0007] As a preferred technical solution of this application, the anti-tipping structure includes a displacement seat slidably connected to the outer ring of the guide rod and an abutment plate bolted to the side wall of the file rack, wherein the displacement seat and the abutment plate are connected by a connecting plate.

[0008] As a preferred technical solution of this application, the elastic connection structure includes a return spring and a damper disposed inside the return spring. One end of the return spring is connected to one side of the U-shaped plate, and the other end is connected to the side wall of the moving plate.

[0009] As a preferred technical solution of this application, a circular groove is provided on the top of one side and the bottom of one side of the U-shaped plate, and a circular rod connected to the movable plate is slidably connected inside the circular groove.

[0010] As a preferred technical solution of this application, a vertical groove is provided on one side of the vertical plate, and the vertical adjustment structure includes a sliding plate slidably connected inside the vertical groove and a lead screw rotatably connected inside the vertical groove. The lead screw is threadedly engaged with the sliding plate, and one end of the lead screw rotatably passes through the top of the vertical plate and is connected to a handle.

[0011] As a preferred technical solution of this application, one side of the sliding plate is connected to the side wall of the U-shaped plate, and one side of the vertical plate is fixedly connected to the displacement seat bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By installing guide rods on both sides of the filing shelf and an anti-tipping structure that slides with them, and by fixing the guide rods stably to the base plate through a connecting frame, a dual constraint is formed on the lateral displacement and tilting tendency of the filing shelf. This significantly enhances the structural stability of the shelf during dynamic movement and reduces the risk of shelf deformation and guide rail damage caused by tipping. Simultaneously, the protective frames on both sides of the base plate integrate a one-way limiting and locking system consisting of a toothed plate, a movable plate, an upper inclined surface, a lower inclined surface, a U-shaped plate, an elastic connecting structure, and a vertical adjustment structure. This allows for flexible switching of the filing shelf according to actual usage needs. The design allows for reliable one-way or two-way locking, avoiding the safety hazards associated with traditional devices that rely solely on manual positioning or static limit blocks. This design not only enhances the safety and controllability of the operation process but also reduces collisions or tipping accidents caused by misoperation, effectively protecting the personal safety of on-site personnel. The moving plate is connected to the U-shaped plate through an elastic connection structure, providing buffering and automatic reset capabilities during engagement with the toothed plate. This allows the file rack to smoothly pass over the toothed structure during normal movement and quickly lock under reverse force, balancing ease of operation with safety performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides an adjustable file rack anti-tipping reinforcement device, such as... Figures 1-5 As shown, the adjustable file rack anti-tipping reinforcement device includes a base plate 2 and several file racks 1 connected to the top of the base plate 2 by a pulley structure. Guide rods 8 are provided on both sides of the file rack 1. Both ends of the guide rods 8 are connected to the top of the base plate 2 through connecting frames 6. The surface of the guide rods 8 is slidably provided with an anti-tipping structure that cooperates with the side wall of the file rack 1. The top two sides of the base plate 2 are provided with protective frames 4. The inner side wall of the protective frame 4 is bolted to a toothed plate 5. A movable plate 10 is provided on one side of the toothed plate 5. An upper inclined surface 11 that cooperates with the toothed plate 5 is opened on the top of one side of the movable plate 10. A lower inclined surface 12 that cooperates with the toothed plate 5 is opened on the bottom of the other side of the movable plate 10. A U-shaped plate 15 is provided on one side of the movable plate 10. An elastic connection structure that cooperates with the U-shaped plate 15 is provided on the side wall of the movable plate 10. A vertical plate 16 is provided on one side of the U-shaped plate 15, which is connected to the side wall of the anti-tipping structure. A vertical adjustment structure that cooperates with the U-shaped plate 15 is provided on one side of the vertical plate 16.

[0017] Specifically, the adjustable file rack 1 is slidably connected to the top of the base plate 2 via a pulley structure at its bottom, allowing it to move back and forth along the length of the base plate 2 to meet the flexible adjustment needs of dense storage space. Anti-tipping structures are installed on the side walls of the file rack 1 to cooperate with guide rods 8. The guide rods 8 are fixedly connected to the top of the base plate 2 via connecting brackets 6 at both ends, forming a stable guiding support system. When the file rack 1 tilts back and forth due to uneven weight distribution of the files or sudden changes in operating force during pushing and pulling, the anti-tipping structure slides along the guide rods 8 and... The lateral constraint of the guide rod 8 effectively limits the swing amplitude of the file rack 1 in the front-to-back direction, preventing it from tipping over. Meanwhile, inside the protective frames 4 located on both sides of the top of the base plate 2, toothed plates 5 are bolted together. These toothed plates 5 form a one-way limiting relationship with the upper inclined surface 11 and lower inclined surface 12 on the moving plate 10. When the file rack 1 needs to move in one direction, the operator adjusts the vertical adjustment structure, causing the vertical plate 16 to move the U-shaped plate 15 downwards. This, in turn, pushes the moving plate 10 downwards through the elastic connection structure, causing the upper inclined surface... When the upper inclined surface 11 engages with the toothed plate 5, it slides along the toothed structure of the toothed plate 5 when the file rack 1 moves forward, achieving smooth one-way passage. When attempting to move in the opposite direction, the slope structure of the upper inclined surface 11 is blocked by the toothed plate 5, thus achieving a reverse locking function. When it is necessary to move the file rack 1 in the opposite direction, the vertical adjustment structure is operated again to lift the vertical plate 16 upward, causing the U-shaped plate 15 and the moving plate 10 to move upward as a whole, so that the lower inclined surface 12 engages with the toothed plate 5. At this time, the inclined structure of the lower inclined surface 12 allows the file rack 1 to slide backward, while it is blocked by the toothed plate 5 when moving forward. Plate 5 is locked in place, achieving one-way locking during reverse movement. When no movement is required and the file rack 1 needs to be completely fixed, the vertical adjustment structure can be adjusted to the middle position, so that the moving plate 10 can be limited both up and down. Alternatively, the pre-tightening force of the elastic connection structure can keep the moving plate 10 in contact with the toothed plate 5, forming a two-way locking effect. Since the moving plate 10 is connected to the U-shaped plate 15 through the elastic connection structure, it can produce elastic deformation when squeezed by the toothed plate 5 during movement, achieving automatic repositioning and reset, avoiding jamming and ensuring smooth operation.

[0018] The anti-tipping structure includes a displacement seat 9 that is slidably connected to the outer ring of the guide rod 8 and an abutment plate 3 that is bolted to the side wall of the file rack 1. The displacement seat 9 and the abutment plate 3 are connected by a connecting plate 7.

[0019] The elastic connection structure includes a return spring 14 and a damper 20 disposed inside the return spring 14. One end of the return spring 14 is connected to one side of the U-shaped plate 15, and the other end is connected to the side wall of the movable plate 10.

[0020] The top and bottom sides of the U-shaped plate 15 are provided with circular grooves, and a circular rod 13 connected to the movable plate 10 is slidably connected inside the circular groove.

[0021] Specifically, through the cooperation of the displacement seat 9, the contact plate 3, and the connecting plate 7 in the anti-tipping structure, the displacement seat 9 is slidably sleeved on the outer ring of the guide rod 8, and the contact plate 3 is fixed to the side wall of the file rack 1 by bolts. The two are rigidly connected by the connecting plate 7. When the file rack 1 moves back and forth or tilts under force, the displacement seat 9 slides synchronously along the guide rod 8. The connecting plate 7 transmits the lateral displacement and overturning tendency of the file rack 1 to the guide rod 8 system. The guide rod 8 provides lateral support reaction force to limit its excessive swing, thereby enhancing the connection stability between the anti-tipping structure and the file rack 1 and ensuring the reliable transmission of the guiding and limiting functions. At the same time, it is convenient for disassembly and maintenance, and improves the overall structural adaptability and assembly flexibility of the device. Through the cooperation of the return spring 14 and the damper 20 in the elastic connection structure, one end of the return spring 14 is connected to the U-shaped plate 15, and the other end is connected to the moving plate 10. The damper 20 is set inside it. When the moving plate 10 is squeezed or... During the rebound action, the return spring 14 provides elastic restoring force to achieve automatic reset, while the damper 20 buffers and controls the deformation process of the spring, suppressing high-frequency vibration and impact. This achieves the effect of enabling the moving plate 10 to have good dynamic response performance during the meshing process with the toothed plate 5, ensuring smooth one-way passage and avoiding impact noise and structural damage caused by excessively fast spring rebound, thus improving operational stability and service life. Through the cooperation of the circular groove on the U-shaped plate 15 and the circular rod 13, the circular rod 13 is slidably connected in the circular grooves at the top and bottom of the U-shaped plate 15. The other end of the circular rod 13 is fixedly connected to the moving plate 10. This structure, together with the return spring 14 and the damper 20, constitutes a guiding and elastic composite connection system, preventing deflection or jamming during elastic deformation. This achieves the effect of improving the movement accuracy and stability of the moving plate 10, ensuring that the upper inclined surface 11 and the lower inclined surface 12 can be accurately aligned with the toothed plate 5, and ensuring the reliability of the one-way locking function.

[0022] A vertical groove is provided on one side of the vertical plate 16. The vertical adjustment structure includes a sliding plate 17 that is slidably connected inside the vertical groove and a lead screw 18 that is rotatably connected inside the vertical groove. The lead screw 18 is threadedly engaged with the sliding plate 17. One end of the lead screw 18 rotatably passes through the top of the vertical plate 16 and is connected to a handle 19.

[0023] One side of the sliding plate 17 is connected to the side wall of the U-shaped plate 15, and one side of the vertical plate 16 is bolted to the displacement seat 9.

[0024] Specifically, through the cooperation of the vertical groove on the vertical plate 16 with the sliding plate 17, the lead screw 18, and the handle 19, the sliding plate 17 is slidably connected in the vertical groove, and the lead screw 18 passes through the vertical groove and is threadedly engaged with the sliding plate 17. Its top extends out of the vertical plate 16 and is connected to the handle 19. When the operator turns the handle 19, it drives the lead screw 18 to rotate, driving the sliding plate 17 to move smoothly up and down in the vertical groove, thereby driving the U-shaped plate 15 connected to it to achieve precise lifting and lowering, thus controlling the meshing position of the moving plate 10 and the toothed plate 5. This achieves the effect of providing a manually adjustable and continuously controllable vertical adjustment method, allowing the device to flexibly switch the moving direction or lock the state. The operation is intuitive and convenient, the adjustment accuracy is high, and it meets the needs of different applications. Safety control requirements in the scenario; through the connection and cooperation of sliding plate 17 and U-shaped plate 15, and vertical plate 16 and displacement seat 9, one side of sliding plate 17 is fixedly connected to U-shaped plate 15, and vertical plate 16 is fixedly connected to displacement seat 9 by bolts, so that the entire vertical adjustment structure and anti-tipping structure form a linkage system. When the file rack 1 moves as a whole, displacement seat 9 moves synchronously with it, and vertical plate 16 moves accordingly, thereby driving sliding plate 17, lead screw 18 and other adjustment components to move together, ensuring that the vertical adjustment structure always maintains a relatively static relationship with file rack 1, achieving the effect of integrated movement of adjustment mechanism and file rack, avoiding interference or failure caused by structural separation, and enhancing the integration and operational coordination of the system.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
