Description

Technical Field

[0001] This utility model relates to the field of data display equipment technology, and in particular to a multifunctional data rack. Background Technology

[0002] Document racks, as common devices for storing and displaying documents, books, or promotional materials, are widely used in office and business activities. In the technology service sector, the use of document racks is more complex, requiring not only the storage of traditional paper documents but also digital documents and specialized materials of varying thicknesses, such as technology service solution manuals and technical parameter sheets. Existing document racks are structurally welded or bolted, resulting in pre-set and unchangeable spacing between shelves. This fixed spacing wastes vertical space when storing documents of varying thicknesses, limits the rack's versatility for different document sizes, reduces space utilization efficiency, and fails to meet the diverse document storage needs of technology service scenarios.

[0003] Furthermore, commercially available document racks are primarily designed for fixed-location use, resulting in bulky structures that lack easy mobility. However, technology service activities often involve multiple scene transitions, such as booth adjustments at technology exhibitions, meeting room setups for internal technical seminars, and relocation of service points in open-plan offices. Moving fully loaded document racks is extremely difficult when these scenarios require reconfiguration, significantly reducing work efficiency and flexibility. More importantly, technology services often require the transport of auxiliary display tools such as small projectors and portable printers. Existing document racks cannot integrate and store these devices, necessitating additional personnel for transport, further increasing the complexity of scene transitions and failing to meet the high mobility requirements of modern technology service environments.

[0004] Furthermore, traditional information racks have a very limited function, confined to storing and displaying materials, lacking additional functional components that can integrate and display event themes or project guidance information. In situations like technology platform services where dynamic information dissemination is required, users often need to display real-time updated service processes, technical achievement case data, interactive consultation QR codes, event agendas, and schedules, etc. Traditional information racks cannot integrate and display this information. Users must use separate display boards, poster stands, or electronic displays, which not only increases equipment configuration costs but also makes the overall layout appear cluttered, making it difficult to unify the style of various equipment and create a professional and neat visual image for technology services, which is detrimental to improving the experience and trust of service recipients.

[0005] Therefore, this utility model proposes a multifunctional document holder to address the shortcomings of the prior art. Utility Model Content

[0017] Example: Please refer to Figures 1 to 5 This utility model embodiment provides a multifunctional document holder, including a base 1 that serves as the mounting base for the entire device, a bracket 3 mounted on the base 1, a slider 4 that is slidably sleeved on the bracket 3, and a shelf 9 supported by the slider 4.

[0018] The top of the base 1 has a groove 205 for inserting and fixing the lower end of the bracket 3. The bracket 3 is stably connected to the base 1 by cooperating with the groove 205. The bottom of the base 1 is provided with a portable mechanism 2, which includes a rotating shaft 207 fixed to the bottom of the base 1 and a wheel 208 rotatably sleeved on the rotating shaft 207. The rolling of the wheel 208 enables convenient movement of the entire document holder. The outer wall of the bracket 3 has an adjustment port 5 along the length direction. The slider 4 is slidably mounted on the bracket 3. The slider 4 has a through fixing hole 6. A pluggable fixing strip 7 passes through the fixing hole 6 and can be selectively inserted into the adjustment port 5 to lock the slider 4 at any height position on the bracket 3.

[0019] A shelf 201 is fixed to the top of the bracket 3. The bottom of the shelf 201 has a groove 206 for fitting and fixing the top of the bracket 3. The outer periphery of the shelf 201 is provided with a protective sleeve 202 for protection. An extension plate 203 is detachably hung on the front side of the shelf 201. A hook 204 is provided on the rear side of the extension plate 203. The extension plate 203 is hung on the shelf 201 by the hook 204 for displaying thematic information. A multifunctional document holder also includes a connecting strip 10. The bottom of the shelf 9 has a connecting hole 11. The connecting strip 10 passes through the connecting hole 11. At the same time, the connecting strip 10 is supported on the slider 4, so that the shelf 9 can pivot to open or close around the connecting strip 10. The front end of the slider 4 is also provided with a limiting block 8 for abutting and supporting the shelf 9 after it has pivoted and unfolded. The limiting block 8 is located at the front end of the slider 4 and below the connecting strip 10 to prevent the shelf 9 from over-flipping upwards.

[0020] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The fixing strip 7 is a pluggable rod-shaped structure. The outer diameter of the fixing strip 7 is adapted to the fixing hole 6 on the slider 4 and the adjustment port 5 on the bracket 3. It is used to pass through the fixing hole 6 and the adjustment port 5 to achieve locking. The adjustment ports 5 are arranged in a vertical array on the side wall of the column of the bracket 3. The adjustment port 5 is a through hole for the fixing strip 7 to be inserted. During operation, the fixing strip 7 is horizontally passed through the fixing hole 6 on the slider 4 and further inserted into the adjustment port 5 on the bracket 3. The function of the fixing strip 7 is to occupy the space of the fixing hole 6 and the adjustment port 5 at the same time through its own rod structure, thereby preventing the slider 4 from sliding relative to the bracket 3.

[0021] The slider 4 is provided with a horizontal through-hole 6. The inner cavity contour of the slider 4 matches the outer wall contour of the bracket 3, so that the slider 4 can slide smoothly along the length of the bracket 3. The axial direction of the fixing hole 6 and the axial direction of the hole of the adjustment port 5 can be aligned when the slider 4 moves to a specific height position. In the assembled state, the inner cavity of the slider 4 slides against the outer wall of the bracket 3. The user can move the slider 4 up and down. When the fixing hole 6 of the slider 4 is aligned with the selected target adjustment port 5, the fixing strip 7 is inserted to lock it. This ensures that the slider 4 can be reliably fixed on the bracket 3 when bearing the weight of the shelf 9. It is also easy to assemble and disassemble, realizes the quick adjustment of the height position of the shelf 9, and meets the needs of placing materials of different sizes.

[0022] The limiting block 8 is integrally formed or fixedly connected to the front end of the slider 4, and the position of the limiting block 8 is lower than the connecting strip 10 supporting the shelf 9. When the shelf 9 is pivoted upward from the folded state, the lower surface of the shelf 9 will abut against the upper surface of the limiting block 8, thereby preventing the shelf 9 from continuing to flip upward, ensuring the stability of the data placed on the shelf 9, and effectively improving the safety of use.

[0023] To ensure the entire multi-functional document holder is easily movable, please refer to... Figure 2 The base 1 has a portable mechanism 2 at its bottom. The portable mechanism 2 includes a rotating shaft 207 fixed to the bottom of the base 1 and a wheel 208 rotatably mounted on the rotating shaft 207. The wheel 208 can rotate freely around the rotating shaft 207, so that the entire device can be easily pushed to meet the needs of rapid deployment between different service areas.

[0024] To ensure the stability and detachability of the connection between bracket 3 and base 1, please refer to... Figure 1 The top surface of the base 1 has a groove 205. The inner contour shape of the groove 205 matches the cross-sectional shape of the lower end of the bracket 3. The lower end of the bracket 3 is installed in the groove 205 by vertical insertion. This connection method is simple in structure, which can ensure the vertical stability of the bracket 3 during use and facilitate the removal of the bracket 3 from the base 1 during transportation or storage.

[0025] To create additional storage space at the top of bracket 3, please refer to... Figure 1 The top of the bracket 3 is fixed with a shelf 201. The bottom of the shelf 201 is provided with a groove 206 for fitting and fixing the top of the bracket 3. The inner wall of the groove 206 fits tightly with the outer wall of the top of the bracket 3, so that the shelf 201 is securely installed at the top of the bracket 3. It can be used to place flower pots, signs and other items.

[0026] To improve device safety and avoid damage from accidental collisions, please refer to... Figure 1 The outer periphery of the shelf 201 is provided with a protective sleeve 202. The protective sleeve 202 is preferably made of elastic cushioning material such as rubber or silicone. The protective sleeve 202 is fixed to the edge of the shelf 201 by covering or bonding. When the shelf 201 collides with the wall or other objects, the protective sleeve 202 can play a cushioning role to protect the equipment and the user.

[0027] To enable the data rack to display thematic information, please refer to... Figure 1 and Figure 3 An extension board 203 is detachably attached to the front of the shelf 201. A hook 204 is integrally formed or fixedly connected to the rear of the extension board 203. The hook 204 is a downwardly curved hook structure. By hanging the hook 204 on the front edge of the shelf 201, the extension board 203 can be easily installed or removed for displaying the event name, platform introduction, and other information.

[0028] To further clarify the structural relationship of the limiting block 8 in preventing the shelf 9 from over-twisting, please refer to... Figure 4 The limiting block 8 is fixedly set at the front end of the slider 4, and in the vertical direction, the upper support surface of the limiting block 8 is located below the connecting strip 10. This positional layout ensures that when the shelf 9 is flipped upward to the working position, the shelf 9 will be naturally supported by the upper support surface of the limiting block 8, thereby achieving stable and reliable limiting.

[0029] Working principle: When the height of the shelf 9 needs to be adjusted, the user first pulls out the fixing strip 7 from the fixing hole 6 and the adjustment port 5. At this time, the lock between the slider 4 and the bracket 3 is released, and the slider 4 can slide freely along the length of the bracket 3. The user moves the slider 4 to the desired height position, aligning the fixing hole 6 on the slider 4 with the corresponding adjustment port 5 on the bracket 3. Then, the fixing strip 7 is reinserted into the aligned fixing hole 6 and adjustment port 5. Since the rod of the fixing strip 7 occupies the space of both the fixing hole 6 and the adjustment port 5, the slider 4 is reliably locked in the new position. Through this pin-type cooperative locking action of the slider 4, the fixing strip 7, and the adjustment port 5 on the bracket 3, the flexible adjustment of the spacing of the shelf 9 is achieved, solving the problem of fixed structure and low space utilization in the existing technology of document rack.

[0030] When materials need to be placed, the user pivots upwards to open the shelf 9. The shelf 9 will rotate around the connecting bar 10 supported by the slider 4. When the shelf 9 rotates to the horizontal working position, the rear end of the lower surface of the shelf 9 will abut against the limiting block 8 at the front end of the slider 4. Since the limiting block 8 is located below the connecting bar 10, the limiting block 8 provides stable support for the shelf 9, effectively preventing the shelf 9 from continuing to flip upwards excessively, thus ensuring the stability and safety when placing materials. When the entire device needs to be moved, the wheels 208 in the portable mechanism 2 at the bottom of the base 1 can roll easily, realizing the rapid deployment of the device in different locations. The top shelf 201 provides additional storage space, while the extension board 203, which is hung by the hook 204, can be used to display thematic information, enhancing the functionality of the device as a platform service tool.
