Description

Technical Field

[0001] This utility model relates to a cable storage box, specifically a retractable multimedia cable storage box for exhibition halls, and belongs to the technical field of cable storage boxes. Background Technology

[0002] Exhibition halls, as important venues for showcasing corporate image, product technology, or cultural content, typically integrate various multimedia devices such as projectors, displays, audio equipment, and interactive devices. The normal operation of these devices relies on numerous cable connections, including power cords, HDMI cables, and network cables, resulting in a complex and tangled web of cables within the exhibition hall. Currently, conventional cable management methods mostly involve fixed storage boxes or simple bundling.

[0003] However, because the internal space of a fixed storage box is fixed, it is difficult to accommodate cables of different quantities and specifications. When adding new equipment or replacing cables, the lack of storage space often leads to the stacking and compression of cables, which not only affects heat dissipation but may also cause problems such as wear on the cable sheath and loosening of the interface, which in turn leads to unstable signal transmission or even equipment failure. Utility Model Content

[0004] The purpose of this utility model is to provide a retractable multimedia cable storage box for exhibition halls in order to solve the above-mentioned problems. The rotating positioning block separates it from the side wall of the fixed plate. Pulling the pull rod causes it to slide the locking rod in the sliding groove. The locking frame slides away from the fixed frame, which increases the accommodation space between the locking frame and the fixed frame. This helps to prevent the cable from being stacked and squeezed due to insufficient storage space, thus affecting the heat dissipation of the storage box.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a retractable multimedia cable storage box for exhibition halls, including a mounting plate, a fixed frame fixedly connected to the mounting plate, a slotted frame slidably installed inside the fixed frame, a positioning mechanism fixed on the fixed frame and the slotted frame, the positioning mechanism including a fixed plate and a sliding groove, a fixed plate fixedly connected to the side wall of the fixed frame, a sliding groove provided inside the fixed plate, a slotted rod slidably installed in the sliding groove, a positioning block threadedly connected to the slotted rod, the positioning block abutting against the fixed plate, a pull rod fixedly installed on the slotted rod, the pull rod being fixedly connected to the slotted frame, a sealing mechanism engaging and installed on the fixed frame and the slotted frame, and several sets of cable clamping mechanisms engaging and installed inside the mounting plate.

[0006] Preferably, the diameter of the end of the clamping rod near the fixed plate is larger than the diameter of the end of the clamping rod near the pull rod, and the diameter of the longer end of the clamping rod is equal to the width of the slide groove.

[0007] Preferably, the shorter end of the clamping rod is located inside the fixing plate, the pull rod is located at the end of the clamping rod away from the fixing frame, and the clamping frame is slidably connected to the mounting plate.

[0008] Preferably, the sealing mechanism includes a second cover plate and a connecting plate, the top of the card frame is fitted with the second cover plate and the connecting plate, and the second cover plate and the connecting plate are fixedly connected, and the top of the fixed frame is fitted with the first cover plate.

[0009] Preferably, the length of the connecting plate is greater than the length of the second cover plate, and the first cover plate, the second cover plate, and the connecting plate are all in communication with the interior of the fixing frame and the card frame.

[0010] Preferably, the connecting plate and the first cover plate are slidably connected, and the thickness of both the first cover plate and the second cover plate is greater than the thickness of the connecting plate.

[0011] Preferably, the wire clamping mechanism includes a clamping slot and a wire clamping block. The mounting plate has several sets of clamping slots at equal intervals. The clamping slots are fitted with wire clamping blocks, and the top of the wire clamping blocks has an arc-shaped structure.

[0012] Preferably, several sets of the wire-clamping blocks are located inside the fixed frame and the clamping frame, and the bottom end of the wire-clamping block is engaged with the mounting plate.

[0013] Preferably, the wire clamping mechanism further includes a wire feeding groove. Both the fixing frame and the clamping frame are provided with wire feeding grooves. A gasket is adhered to the part of the fixing frame and the clamping frame near the wire feeding groove. The gasket is arranged with an arc surface structure.

[0014] Preferably, the wire clamping mechanism further includes a through groove, and both sides of the fixing frame and the clamping frame are provided with through grooves, which are located near the pull rod of the fixing frame and the clamping frame.

[0015] The beneficial effects of this utility model are as follows: Before adding new equipment or replacing cables, the positioning block can be rotated using a tool. The positioning block is threaded onto the side wall of the clamping rod and abuts against the fixing plate installed on the fixing frame. When it is rotated to a state where it is separated from the side wall of the fixing plate, the operator can pull the pull rod fixed on the clamping frame by hand. Since the other end of the pull rod is fixed to the end of the clamping rod, the pull rod slides, causing the clamping rod to move in the sliding groove provided in the fixing plate. When the clamping rod slides towards the clamping frame, it can cause the clamping frame to move away from the fixing frame, thereby increasing the distance between the clamping frame and the fixing frame. This increases the accommodating space between the clamping frame and the fixing frame, which helps to prevent the cables from being stacked and squeezed due to insufficient storage space, thus affecting the heat dissipation inside the storage box. After adjusting the accommodating space of the storage box, the positioning block is rotated back to a state where it abuts against the side wall of the fixing plate, and then the clamping frame is fixed and limited by the friction between the positioning block and the fixing plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7As shown, a retractable multimedia cable management box for exhibition halls includes a mounting plate 1. A fixed frame 2 is fixedly connected to the mounting plate 1. A retaining frame 3 is slidably installed inside the fixed frame 2. The retaining frame 3 is slidably connected to the mounting plate 1. A positioning mechanism 4 is fixed to the fixed frame 2 and the retaining frame 3. The positioning mechanism 4 includes a fixed plate 404 and a sliding groove 405. The fixed plate 404 is fixedly connected to the side wall of the fixed frame 2. The sliding groove 405 is provided inside the fixed plate 404. A retaining rod 402 is slidably installed in the sliding groove 405. The diameter of the retaining rod 402 near the fixed plate 404 is larger than the diameter of the retaining rod 402 near the pull rod 401. The diameter of the longer end of the retaining rod 402 is equal to the width of the sliding groove 405. The shorter end of the retaining rod 402 is located inside the fixed plate 404. A positioning block 403 is threadedly connected to the retaining rod 402. The positioning block 403 can be rotated to separate it from the side wall of the fixing plate 404; the positioning block 403 abuts against the fixing plate 404, and a pull rod 401 is fixedly installed on the locking rod 402. When the pull rod 401 is pulled, the locking rod 402 will slide in the sliding groove 405. When the locking rod 402 slides towards the locking frame 3, it will drive the locking frame 3 to move away from the fixing frame 2, thereby increasing the distance between the locking frame 3 and the fixing frame 2, so that the storage space between the two can be expanded. This adjustable design can effectively avoid the stacking and squeezing of cables due to insufficient storage space, ensure air circulation inside the storage box, improve heat dissipation, and reduce the risk of cable failure due to high temperature; the pull rod 401 is fixedly connected to the locking frame 3, and a sealing mechanism 5 is engaged on the fixing frame 2 and the locking frame 3. Several sets of cable clamping mechanisms 6 are engaged in the mounting plate 1.

[0026] As a technical optimization of this utility model, the sealing mechanism 5 includes a second cover plate 502 and a connecting plate 503. The top of the frame 3 is fitted with the second cover plate 502 and the connecting plate 503, and the second cover plate 502 and the connecting plate 503 are fixedly connected. The top of the fixed frame 2 is fitted with a first cover plate 501. The length of the connecting plate 503 is greater than the length of the second cover plate 502, and the first cover plate 501, the second cover plate 502, and the connecting plate 503 are all in communication with the interior of the fixed frame 2 and the frame 3. The connecting plate 503 is connected to the first cover plate 501. The two sides slide together. After the cable is stored, the first cover plate 501 is snapped onto the top of the fixed frame 2, and then the second cover plate 502 and the connecting plate 503 are snapped onto the top of the frame 3. The connecting plate 503 can slide along the first cover plate 501 to achieve seamless connection during the extension and retraction process. This effectively prevents dust and debris from entering the storage box and ensures that the cable is stored in a clean and safe environment. At the same time, it improves the overall aesthetics and coordination of the storage box, making it better suited to the display needs of the exhibition hall. The thickness of the first cover plate 501 and the second cover plate 502 is greater than the thickness of the connecting plate 503.

[0027] As a technical optimization of this utility model, the cable clamping mechanism 6 includes a clamping slot 604 and a cable clamping block 605. Several sets of clamping slots 604 are equidistantly arranged inside the mounting plate 1. Cable clamping blocks 605 are engaged with the clamping slots 604. These sets of cable clamping blocks 605 are located inside the fixing frame 2 and the clamping frame 3. The bottom end of each cable clamping block 605 is engaged with the mounting plate 1. Due to the arc-shaped structure design at the top of the cable clamping block 605, it can fix the cable while preventing damage from excessive bending. Both the fixing frame 2 and the clamping frame 3 are provided with cable feeding grooves 60. 3. A gasket 602 is glued to the part of the fixed frame 2 and the card frame 3 near the cable tray 603. The gasket 602 is set with an arc surface structure. The gasket 602 can further buffer the friction between the cable and the storage box and protect the integrity of the cable sheath. Both sides of the fixed frame 2 and the card frame 3 are provided with through slots 601. The through slots 601 are located near the pull rod 401 of the fixed frame 2 and the card frame 3. The cable can be introduced through the through slots 601 on the fixed frame 2 and the card frame 3, guided by the cable tray 603, and then inserted into the cable clamping block 605 in the card tray 604 of the mounting plate 1.

[0028] When using this utility model, before adding new equipment or replacing cables, the operator can use a screwdriver or other tools to rotate the positioning block 403. The positioning block 403 is threaded onto the side wall of the clamping rod 402 and abuts against the side wall of the fixing plate 404 installed on the fixing frame 2. By rotating the positioning block 403, it can be separated from the side wall of the fixing plate 404. At this time, the operator pulls the pull rod 401 fixed on the clamping frame 3 by hand. Since the other end of the pull rod 401 is fixed to the end of the clamping rod 402, when the pull rod 401 is pulled, the clamping rod 402 will slide in the groove 405 provided in the fixing plate 404. When the clamping rod 402... When the cable tray is slid towards the card frame 3, it will move the card frame 3 away from the fixed frame 2, thereby increasing the distance between the card frame 3 and the fixed frame 2 and expanding the storage space between them. This adjustable design can effectively prevent the cables from being piled up and squeezed due to insufficient storage space, ensure air circulation inside the storage box, improve heat dissipation, and reduce the risk of cable failure due to high temperature. After adjusting the storage space of the storage box according to the actual number and specifications of cables, the operator rotates the positioning block 403 again so that it is in close contact with the side wall of the fixed plate 404 again. At this time, a gap is formed between the positioning block 403 and the fixed plate 404. The friction generated provides a stable limiting effect on the clamping rod 402, thereby fixing the position of the clamping frame 3 and ensuring that the telescopic structure of the storage box remains stable during equipment operation and cable use, without loosening or displacement. When storing the cable inside the fixing frame 2 and the clamping frame 3, the cable can be introduced through the through slot 601 on the fixing frame 2 and the clamping frame 3, guided by the cable release slot 603, and then inserted into the cable clamping block 605 in the clamping slot 604 of the mounting plate 1. Due to the arc-shaped structure design at the top of the cable clamping block 605, it can fix the cable and prevent the cable from being damaged due to excessive bending. At the same time, the fixing frame 2 and the clamping frame 3 are close to the cable release slot 604. The gasket 602, which is bonded to the cable tray 603, can further buffer the friction between the cable and the storage box, protecting the integrity of the cable sheath. After the cable is stored, the first cover plate 501 is snapped onto the top of the fixed frame 2, and then the second cover plate 502 and the connecting plate 503 are snapped onto the top of the frame 3. The connecting plate 503 can slide along the first cover plate 501 to achieve seamless connection during the extension and retraction process, effectively preventing dust and debris from entering the storage box and ensuring that the cable is in a clean and safe storage environment. At the same time, it improves the overall aesthetics and coordination of the storage box, making it better suited to the display needs of the exhibition hall.
