Description

Technical Field

[0001] The utility model relates to the field of file trays, in particular to a high-strength pressure-resistant file tray. Background Art

[0002] In daily life and work, file management and storage is a vital task. Whether in home, office or other organizations, people need to effectively manage and store files so that they can be consulted and used at any time. However, traditional file storage devices may deform, damage or collapse when faced with pressure and weight, especially when there are a large number of files or limited storage space. To solve this problem, existing file tray designs usually use reinforced structures or materials to enhance their load-bearing capacity. However, these designs often have some shortcomings, such as complex structure, high manufacturing cost, and inconvenience in use.

[0003] The existing patents have made some improvements, but there are still some shortcomings. For example, the patent with publication number CN217435368U discloses a multi-layer file tray. 1. This patent sets slots on the outside of the file tray and fixes and connects the multi-layer file tray through four connecting rods. This setting will cause a problem. Since the force points of the file tray are all concentrated at the slot positions on the outside, when the file tray is subjected to external pressure, these slots will be subjected to greater forces. This concentrated force situation may cause the outside of the file tray to deform or be damaged, and the file tray has poor stability when it is stacked in multiple layers or bears a large number of files, and is prone to tilting or collapse. 2. External wind or other external factors can cause the files to be blown off, which will cause the files to be scattered and lost, affecting the neatness and safety of the files, and also increasing the management and maintenance costs of the files.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution: a high-strength pressure-proof file tray, comprising a plurality of file tray bodies 1, a support mechanism 2 plugged into the left and right sides of the file tray body 1, and a file fixing mechanism 3 fixed in the middle of the inner edge of the file tray body 1; the file tray body 1 is the main part of the file tray, which is used to store files or other materials. Its function is to provide storage space so that files can be placed and sorted in an orderly manner, kept tidy and easy to manage. The support mechanism 2 is located on the left and right sides of the file tray body 1, and plays a role in supporting and stabilizing the file tray. The design of the support mechanism can ensure that the file tray remains stable when subjected to external pressure, and avoids deformation or tilting due to pressure. The file fixing mechanism 3 is located in the middle of the inner edge of the file tray body 1, and is used to fix the position of the file in the file tray. Its function is to prevent the files from becoming loose or disordered during storage, keep the files neat and orderly, and facilitate users to find and use them.

[0026] A plurality of snap-in blocks 11 are symmetrically arranged on both sides of the file tray body 1, a through cross groove 111 is arranged in the middle of the snap-in blocks 11, and a slide groove 12 is arranged on the left side of the file tray body 1. The snap-in blocks 11 are located on the side of the file tray body 1, and their main function is to install the support mechanism 2. The support mechanism 2 is arranged through the sides of every two file tray bodies 1, supporting the file tray body 1 and providing stable support. The design of the snap-in blocks 11 enables the support mechanism 2 to be firmly inserted and fixed on the file tray body 1, ensuring the stability and strength of the entire file tray structure. The slide groove 12 is located on the left side of the file tray body 1, and its function is to leave space for the stretch handle 331 in the file fixing mechanism 3. The file fixing mechanism is used to fix the position of the file in the file tray, and the setting of the slide groove can ensure that the handle in the file fixing mechanism has enough space for operation, which is convenient for users to insert or remove files, and improves the convenience and efficiency of file management. The lower end array of the file tray body 1 is provided with reinforcing ribs 13, which are located at the lower end of the file tray body 1, and their function is to enhance the structural stability and strength of the file tray. The design of the reinforcing ribs can effectively increase the load-bearing capacity of the bottom of the file tray, preventing the file tray from being deformed or damaged when storing a large number of documents or being under pressure.

[0027] The support mechanism 2 is arranged through the sides of every two file tray bodies 1. The support mechanism 2 includes a clamping rod 21. The outer contour of the clamping rod 21 is sequentially provided with a first limit block 22, a support block 23 and a second limit block 24. The first limit block 22 and the second limit block 24 are fixedly connected to the clamping rod 21, and the support block 23 is rotatably connected to the clamping rod 22. The clamping rod 21 is the main part of the support mechanism and is arranged through the sides of every two file tray bodies 1. The design of the clamping rod 21 enables the support mechanism to be firmly connected to the file tray body 1. The first limit block 22 and the second limit block 24: These two limit blocks are respectively located on the outer contour of the clamping rod 21 and are used to limit the insertion depth of the support mechanism. The first limit block 22 and the second limit block 24 are fixedly connected to the clamping rod 21 to ensure that the support mechanism is accurately and firmly positioned when it is plugged into the file tray body 1. The support block 23 is located on the outer contour of the clamping rod 21 and is rotatably connected to the clamping rod 21. The design of the support block 23 enables it to rotate flexibly when the support mechanism is plugged in, so as to adapt to different sizes and shapes of the file tray body 1, thereby improving the applicability and flexibility of the support mechanism.

[0028] The first limit block 22, the support block 23 and the second limit block 24 are cross-shaped. The cross-shaped design of the first limit block 22, the support block 23 and the second limit block 24 specifically refers to that their outer contour presents a cross shape. This design makes these components present a cross-shaped contour in the cross section, which has the following advantages: Enhanced structural stability: The cross-shaped design can increase the lateral support area of ​​the components, improve the stability and strength of the structure, and make the support mechanism more able to withstand external pressure and load. Improved connection accuracy: The cross-shaped shape makes the connection between the limit block and the support block and the clamping rod tighter, and can accurately control the insertion position and angle of the support mechanism, ensuring the stable connection between the support mechanism and the file tray body. Increased support capacity: The cross-shaped design can increase the force-bearing area of ​​the support block, effectively disperse the pressure, and improve the bearing capacity of the support mechanism, so that the file tray can more safely withstand the weight and pressure when storing documents. In summary, the cross-shaped design provides a more stable and reliable structure for the key components of the support mechanism, and enhances the overall stability and bearing capacity of the file tray.

[0029] The support block 23 includes contact parts 231 at the upper and lower ends and a pressure module 232 in the middle. An annular pressure network 2321 is arranged in an array on the pressure module 232. A pressure plate 2322 is arranged at the lower end of the annular pressure network 2321. The annular pressure network 2311 is cross-shaped as a whole. The contact parts 231 are located at the upper and lower ends of the support block 23, and are used to contact with the corresponding parts of the support mechanism or the file tray body 1 to ensure that the support block 23 can be firmly fixed at the desired position.

[0030] The pressure-bearing module 232 is located in the middle of the support block 23, and its function is to bear the external pressure and transmit it to the support mechanism or the file tray 1. An annular pressure-bearing network 2321 is arranged in an array on the pressure-bearing module 232. The design of the annular pressure-bearing network 2321 enables the support block 23 to disperse the pressure more evenly and improve the supporting capacity.

[0031] The design of the annular pressure-bearing network 2321 has the following effects: 1. Enhanced stability: Through the cross structure of the annular pressure-bearing network 2321, a stable mesh support frame is formed, so that the support block 23 can maintain a stable structure when subjected to force and is not easily deformed or deformed. Such a design can improve the overall stability of the support block 23 and ensure that the support mechanism will not become loose or unstable during use. 2. Increased strength: The cross structure of the annular pressure-bearing network 2321 can effectively increase the bearing capacity and strength of the support block 23. By dispersing the pressure to different parts, the annular pressure-bearing network 2321 can effectively reduce the pressure of a single part and improve the overall pressure resistance of the support block 23, thereby ensuring that the file tray is not easily deformed or damaged when carrying a large number of files. 3. Improved stability: The setting of the pressure plate 2322 can increase the pressure-bearing area of ​​the support block 23, further improving its bearing capacity and stability. The pressure plates 2322 are arranged in an array on the annular pressure network 2321, which can evenly disperse the pressure, so that the support block 23 can bear the external pressure more evenly, thereby improving the overall stability and safety of the file tray.

[0032] The support block 23 is designed to improve the stability and load-bearing capacity of the support mechanism, effectively disperse the pressure during the use of the file tray, and ensure the stability and safety of the file tray.

[0033] The file fixing mechanism 3 includes an L-shaped mounting plate 31 fixed to the built-in upper end of the file tray body 1, a compression spring 32 is clamped at the lower end of the L-shaped mounting plate, and a file fixing piece 33 is clamped at the lower end of the compression spring 32. A tension handle 331 is fixed to the outer side of the file fixing piece 33. The L-shaped mounting plate 31 is a component fixed to the built-in upper end of the file tray body 1, and its shape is "L". Its function is to provide a fixed point for installing the file fixing mechanism 3 and ensure that the file fixing mechanism is firmly installed on the top of the file tray body 1. The compression spring 32 is located at the lower end of the L-shaped mounting plate 31 and is clamped at its bottom. The function of the compression spring is to provide elastic support force so that the file fixing piece 33 can move freely and maintain a stable position. The file fixing piece 33 is a component fixed to the compression spring 32, and is used to fix files or other items on the file tray. It applies appropriate pressure to the file through the elastic force of the compression spring to ensure that the file remains in the desired position. The pull handle 331 is fixed on the outside of the file fixing piece 33, and its function is to facilitate the user's operation, so that the user can easily pull the file fixing piece 33 to insert or remove the file. The file fixing mechanism 3 can effectively fix the file on the file tray through the combination of the L-shaped mounting plate, the compression spring, the file fixing piece and the pull handle, and provides a convenient operation method, making the storage and management of the file more convenient and efficient.

[0034] Working principle: The installation process of the multi-layer file disk includes the following steps:

[0035] 1. Preparation: Place the file tray 1 on a horizontal surface and prepare four sets of supporting mechanisms 2.

[0036] 2. Connect the upper file tray: plug the four sets of support mechanisms 2 into the four clamping blocks 11 on the side of the file tray body 1. During the plugging process, ensure that the first limit block 22 of the support mechanism 2 is fully engaged and fixed on the file tray body 1 to ensure a stable connection. Then, the upper end is clamped and positioned by rotating the support block 23.

[0037] 3. Connect the lower file tray: fix and engage the lower file tray body 1 with the second limit block in the support mechanism 2. The completion of this step marks the completion of the installation of the entire multi-layer file tray.

[0038] Working principle analysis:

[0039] When the multi-layer file tray is under pressure, the force process is as follows:

[0040] Stress distribution: The stress points of the entire device are mainly concentrated on the lower surface of the four clamping blocks 11 in the upper file tray body 1 and the upper surface of the four clamping blocks 11 in the lower file tray body 1 and the support mechanism 2. This force distribution method is different from the traditional file tray and has better strength and pressure bearing effect.

[0041] Pressure dispersion: The pressure on the file tray will first be dispersed to the support block 23 through the support mechanism 2, and the overall strength level is improved by the design of the annular pressure-bearing network in the support block 23. The design of the support mechanism 2 enables the pressure to be evenly dispersed, avoiding the situation of excessive local force.

[0042] In summary, the multi-layer file tray can effectively disperse pressure and ensure a stable connection during use through a reasonably designed support mechanism and connection method, and has excellent strength and pressure-bearing effects, providing a reliable solution for file storage.
