Description

Technical Field

[0001] This invention relates to the field of multimedia cable storage technology, specifically to an automatic storage mechanism for multimedia cables. Background Technology

[0002] Multimedia cables are used to transmit high-definition multimedia video signals. They can transmit uncompressed high-definition video and multi-channel audio data with a maximum data transfer rate of 5Gbps. Furthermore, they eliminate the need for digital-to-analog or analog-to-digital conversion before signal transmission, ensuring the highest quality audio and video signal delivery. However, if multimedia cables are not properly stored, they will become tangled and easily accumulate dust. Therefore, storage boxes are typically used to store multimedia cables.

[0003] Most current storage boxes have an automatic storage mechanism inside, which automatically stores the multimedia connection cable using the rebound force of a spring or clockwork. However, in order to ensure that the multimedia connection cable is completely stored inside the storage box, the rebound force of the spring or clockwork is increased. At the same time, excessive rebound force will also cause the rotation speed of the storage roller to increase, and the bending speed of the multimedia connection cable will also increase during storage. This can easily cause damage to the internal circuitry of the multimedia connection cable. Summary of the Invention

[0004] The technical problem of the present invention is to provide an automatic storage mechanism for multimedia connection cables, and to simultaneously slow down the rotation speed of the storage roller when the spring turns the storage roller, so that the multimedia connection cable is slowly and automatically stored and wound on the outer wall of the storage roller.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic storage mechanism for multimedia cables, comprising a storage box and a multimedia cable body. A cover is rotatably mounted on one side of the storage box. The storage box is equipped with a storage rod, and a circular shaft is coaxially fixed to both the upper and lower ends of the storage rod. The lower end of the circular shaft is rotatably connected to the bottom surface of the storage box. A spring is fixedly mounted on the outer wall of the lower end of the circular shaft. The end of the spring away from the lower end of the circular shaft is fixedly mounted to the bottom surface of the storage box. A disc is rotatably connected to the top surface of the storage box, and a disc is fixedly mounted on the lower end of the disc. There are two mirror-distributed mounting blocks, each with a sliding column that passes through and is slidably connected to it; a first pawl is fixedly mounted at one end of each of the two sliding columns, and a limit ring is fixedly mounted at the other end of each of the two sliding columns; a second spring is sleeved on the outer wall of each of the two sliding columns; one end of each of the two second springs is fixedly mounted on the first pawl, and the other end of each of the two second springs is fixedly mounted on the side wall of the mounting block; a turntable is fixedly mounted on the outer wall of the upper end of the circular shaft, and a ratchet groove for cooperating with the movement of the first pawl is opened on the upper end face of the turntable; a ratchet mechanism is provided on the outer wall of the upper end of the circular shaft. As a further embodiment of the present invention, the ratchet mechanism includes a ratchet body, a second pawl that moves in coordination with the ratchet body, a rotating shaft fixedly disposed at the end of the second pawl away from the ratchet body, the upper end face of the rotating shaft passing through the top of the storage box and rotatably connected to the storage box, a knob fixedly disposed at the upper end face of the rotating shaft, and a second torsion spring sleeved on the outer ring surface of the rotating shaft; one end of the second torsion spring is fixedly disposed on the second pawl, and the other end of the second torsion spring is fixedly disposed on the inner top surface of the storage box; As a further embodiment of the present invention, two lead screws are rotatably connected to the bottom surface of the storage box. The two lead screws have the same pitch, and the two lead screws are not on the same horizontal plane at the same position. A limit plate is fixedly provided on the upper end face of each of the two lead screws, and a lifting block is threadedly connected to each of the two lead screws. One side of each of the two lifting blocks is vertically slidably connected to the inner wall of the storage box, and a wire ring is fixedly provided on the other side of each of the two lifting blocks. As a further embodiment of the present invention, a second gear is fixedly provided at the lower end of the outer wall of each of the two lead screws, and a first gear is fixedly provided on the outer wall of the lower end of the round shaft, and the second gear is meshed with the first gear. As a further embodiment of the present invention, the storage box is provided with two elastic ropes inside, and the two elastic ropes are located on both sides of the storage rod. As a further embodiment of the present invention, a through hole is provided at the lower end of the outer wall of the storage rod, and wire take-up holes are provided at the lower ends of both sides of the storage box. The upper surfaces of the two wire take-up holes are rounded on both sides. The multimedia connection cable body passes through the storage box through the wire take-up holes, the wire ring and the through hole. As a further embodiment of the present invention, baffles are rotatably connected to both sides of the storage box, both baffles are located below the cable take-up hole, and a first torsion spring is fixedly provided between both sides of the two baffles and the side wall of the storage box. As a further embodiment of the present invention, a support plate is fixedly provided on both sides of the inner wall of the storage box. Both support plates are located below the cable take-up hole. A slider is slidably connected to the top of both support plates. A first spring is fixedly provided between the slider and the support plate. A frame is fixedly provided on the top of each slider. The frame presses against the upper surface of the baffle. A pull ring is fixedly provided on the lower surface of the baffle.

[0006] Compared with the prior art, the beneficial effects of the present invention are: 1. When the mainspring drives the storage roller to rotate, the ratchet groove on the upper surface of the turntable and the first pawl cooperate with each other, causing the first pawl to slide in the ratchet groove. This allows the sliding pin fixed on the first pawl to slide on the mounting block, driving the limiting ring to fit against the outer wall of the upper round shaft. Through the friction between the limiting ring and the outer wall of the upper round shaft, the rotation speed of the upper round shaft can be reduced, thereby slowing down the storage speed of the multimedia connection cable body by the storage roller. This avoids the problem that when the mainspring drives the storage roller to rotate and the rotation speed of the storage roller cannot be controlled, the multimedia connection cable body will be wound too fast, causing the bending speed of the multimedia connection cable body to increase during storage. This can easily cause damage to the internal circuitry of the multimedia connection cable body.

[0007] 2. This invention controls the pitch distribution on the two lead screws. When the lead screws rotate synchronously with the lower circular shaft, they can drive the wire ring to rise, guiding the multimedia connection cable body to wind around the outer wall of the storage roller in sequence. This avoids the multimedia connection cable bodies overlapping and causing entanglement between the wound parts when the staff pulls the multimedia connection cable bodies later, resulting in local entanglement and twisting, which could damage the internal circuitry of the multimedia connection cable body.

[0008] 3. In the process of storing the multimedia cable body, the connectors at both ends of the multimedia cable body slide the frame into the upper surface of the support plate, so that the baffle automatically rotates to seal the cable take-up hole by the rebound force of the first torsion spring. This not only prevents dust from entering the storage box from the cable take-up hole, but also simultaneously retracts the connectors at both ends of the multimedia cable body into the storage box, protecting the connectors.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] Please see Figure 1 - Figure 9 This invention provides a technical solution: an automatic storage mechanism for multimedia cables, comprising a storage box 1 and a multimedia cable body 4. A cover plate 2 is rotatably mounted on one side of the storage box 1. The storage box 1 is provided with a storage rod 11, and a circular shaft 12 is coaxially fixedly mounted on both the upper and lower ends of the storage rod 11. The lower end of the circular shaft 12 is rotatably connected to the inner bottom surface of the storage box 1. A spring 20 is fixedly mounted on the outer wall of the lower end of the circular shaft 12. The end of the spring 20 away from the lower end of the circular shaft 12 is fixedly mounted on the inner bottom surface of the storage box 1. A disc 19 is rotatably connected to the inner top surface of the storage box 1. Two mirror-distributed mounting brackets are fixedly mounted on the lower end surface of the disc 19. The mounting blocks 27 are each connected by sliding pins 28. One end of each sliding pin 28 is fixedly provided with a first pawl 29, and the other end of each sliding pin 28 is fixedly provided with a limit ring 30. The outer wall of each sliding pin 28 is fitted with a second spring 31. One end of each second spring 31 is fixedly provided on the first pawl 29, and the other end of each second spring 31 is fixedly provided on the side wall of the mounting block 27. A turntable 22 is fixedly provided on the outer wall of the upper end of the round shaft 12. The upper end surface of the turntable 22 is provided with a ratchet groove 35 that cooperates with the movement of the first pawl 29. A ratchet mechanism is provided on the outer wall of the upper end of the round shaft 12.

[0013] Before using this invention, such as Figure 1 As shown, from Figure 1 The front of this device is viewed from the bottom left to the top right. Figure 1 Looking down from above shows the top of this device. The following description will use the device's orientation and will not be repeated.

[0014] In use, the ratchet mechanism is operated to release the upper circular shaft 12. The storage rod 11, through the rebound force of the spring 20 fixed between the lower circular shaft 12 and the bottom surface of the storage box 1, can rotate counterclockwise (viewed from the top of the device). When the storage rod 11 rotates counterclockwise, the upper circular shaft 12 drives the turntable 22 to rotate synchronously. Since the upper surface of the turntable 22 has a ratchet groove 35 for driving the first pawl 29, when the turntable 22 rotates counterclockwise, it can drive the first pawl 29 to slide within the ratchet groove 35. This causes the sliding post 28 fixed on the first pawl 29 to slide on the mounting block 27, so that the limiting ring 30 installed at the end of the sliding post 28 away from the first pawl 29 fits against the outer wall of the upper circular shaft 12 (e.g., ...). Figure 3 and Figure 9 As shown, when the storage rod 11 rotates, the first pawl 29 slides through the ratchet groove 35 on the upper surface of the turntable 22, causing the limiting ring 30 to engage with the upper round shaft 12. This slows down the rotation speed of the upper round shaft 12, thus reducing the rotation speed of the storage rod 11 when driven by the spring 20. This avoids the situation where the storage mechanism inside the traditional storage box 1 cannot control the speed of the multimedia connection cable during storage, which could lead to the multimedia connection cable winding too fast and causing damage. The bending speed of the cable increases during the winding process, which can easily damage the internal wiring of the multimedia connection cable. Since the outer wall of each sliding post 28 is fitted with a second spring 31, which is installed between the first pawl 29 and the mounting block 27, when the first pawl 29 slides within the ratchet groove 35, the second spring 31 allows the first pawl 29 to slide back and forth along the inner wall of the ratchet groove 35, causing the limiting ring 30 to repeatedly contact the upper end of the round shaft 12 (e.g., ...). Figure 3 and Figure 9As shown, the limiting ring 30 intermittently contacts the outer wall of the upper circular shaft 12 via a spring. This prevents the problem that if the limiting ring 30 is in constant contact with the outer wall of the upper circular shaft 12, the spring force of the mainspring 20 in the later stages of rotating the lower circular shaft 12 will be less than the friction between the upper circular shaft 12 and the limiting ring 30, thus preventing further rotation and the exposed multimedia connection cable from being retracted into the storage box 1. When the storage rod 11 rotates clockwise (viewed from the top of the device), the storage rod 11 is coaxially fixed to the upper surface of the circular shaft 12. Shaft 12 drives turntable 22 to rotate. Due to the principle of ratchet groove 35 and first pawl 29, when turntable 22 rotates clockwise, it can drive first pawl 29 to rotate synchronously. Since a sliding post 28 is installed on first pawl 29, and the sliding post 28 passes through and is slidably connected to mounting block 27, mounting block 27 is fixedly installed on the lower end face of disc 19, and the upper end face of disc 19 is rotatably connected to the top surface inside storage box 1, when first pawl 29 rotates clockwise with turntable 22, it can drive disc 19 to rotate clockwise at the top inside storage box 1 (e.g., Figure 9 As shown, the turntable 22, through the cooperation of the first pawl 29 and the ratchet groove 35, can drive the first pawl 29 to slide in the ratchet groove 35 when the turntable 22 rotates counterclockwise. This allows the storage rod 11 to store the multimedia connection cable body 4, and the sliding column 28 can drive the limiting ring 30 to fit against the upper round shaft 12, thereby slowing down the rotation speed of the storage rod 11. When the turntable 22 rotates clockwise, the first pawl 29 can be driven to rotate simultaneously through the principle of the first pawl 29 and the ratchet groove 35. Since the first pawl 29 does not slide, it will not drive the limiting ring 30 to fit against the upper round shaft 12. Therefore, when the staff pulls the multimedia connection cable body 4 out of the storage box 1, it will not be subject to the resistance between the upper round shaft 12 and the limiting ring 30.

[0015] When the spring 20 drives the storage roller 11 to rotate, the ratchet groove 35 on the upper surface of the turntable 22 and the first pawl 29 cooperate with each other, causing the first pawl 29 to slide in the ratchet groove 35. This allows the sliding column 28 fixed on the first pawl 29 to slide on the mounting block 27, driving the limiting ring 30 to fit against the outer wall of the upper round shaft 12. Through the friction between the limiting ring 30 and the outer wall of the upper round shaft 12, the rotation speed of the upper round shaft 12 can be reduced, thereby slowing down the storage speed of the storage roller 11 on the multimedia connection cable body 4. This avoids the problem that when the spring 20 drives the storage roller 11 to rotate and cannot control the rotation speed of the storage roller 11, the multimedia connection cable body 4 will be wound too fast, causing the bending speed of the multimedia connection cable body 4 to increase during storage. This can easily cause damage to the internal circuitry of the multimedia connection cable body 4.

[0016] As a further embodiment of the present invention, the ratchet mechanism includes a ratchet body 21, on which a second pawl 32 is provided to cooperate with the movement of the ratchet body 21. A rotating shaft 33 is fixedly provided at one end of the second pawl 32 away from the ratchet body 21. The upper end face of the rotating shaft 33 passes through the top of the storage box 1 and is rotatably connected to the storage box 1. A knob 3 is fixedly provided on the upper end face of the rotating shaft 33. A second torsion spring 34 is sleeved on the outer ring surface of the rotating shaft 33. One end of the second torsion spring 34 is fixedly provided on the second pawl 32, and the other end of the second torsion spring 34 is fixedly provided on the inner top surface of the storage box 1.

[0017] When using this invention, rotating the knob 3 to retract the cord causes the rotating shaft 33 to rotate on the storage box 1, driving the second pawl 32, which is fixedly mounted on the rotating shaft 33, to move away from the ratchet body 21. At this time, the ratchet mechanism will relax its restriction on the storage rod 11. When the knob 3 is released, the second torsion spring 34, which is fixedly mounted between the second pawl 32 and the inner top surface of the storage box 1, can cause the second pawl 32 to automatically return to the ratchet body 21 and abut against the ratchet body 21 for restriction.

[0018] As a further embodiment of the present invention, two lead screws 15 are rotatably connected to the bottom surface of the storage box 1. The two lead screws 15 have the same pitch, and the two lead screws 15 are not on the same horizontal plane at the same position. A limit plate 16 is fixedly provided on the upper end surface of each of the two lead screws 15. A lifting block 17 is threadedly connected to each of the two lead screws 15. One side of each of the two lifting blocks 17 is vertically slidably connected to the inner wall of the storage box 1, and a guide ring 18 is fixedly provided on the other side of each of the two lifting blocks 17. A second gear 14 is fixedly provided at the lower end of the outer wall of each of the two lead screws 15, and a first gear 13 is fixedly provided on the outer wall of the lower end of the round shaft 12. The second gear 14 is meshed with the first gear 13.

[0019] When the mainspring 20 rotates the lower end of the circular shaft 12, it causes the first gear 13 fixedly mounted on the outer wall of the lower end of the circular shaft 12 to rotate. The first gear 13 is meshed with two second gears 14. Therefore, when the first gear 13 rotates, it can drive the lead screw 15 on the second gear 14 to rotate synchronously, causing the lifting block 17 threadedly connected to the outer wall of the lead screw 15 to rise synchronously. Since the two lead screws 15 are not on the same horizontal plane at the same pitch position, the height of one lifting block 17 is higher than that of the other. When the lifting block 17 rises, it can drive the guide ring 18 to rise synchronously (e.g., Figure 5As shown, the lead rings 18 are not on the same horizontal plane at the same position of the two lead screws 15. When the two lead rings 18 guide the multimedia connection cable body 4 to gradually wind around the outer wall of the lead rod, the multimedia connection cable body 4 guided by the two lead rings 18 will not overlap when winding. This allows the multimedia connection cable body 4 to be stacked and wound around the outer wall of the storage rod 11 in sequence, avoiding the problem of the multimedia connection cable body 4 overlapping and slipping during winding, and then winding itself.

[0020] This invention controls the pitch distribution on the two lead screws 15. When the lead screws 15 rotate synchronously with the lower end of the round shaft 12, they can drive the wire ring 18 to rise, guiding the multimedia connection cable body 4 to wind around the outer wall of the storage rod 11 in sequence. This avoids the multimedia connection cable bodies 4 overlapping together, which could cause entanglement and local twisting when the staff pulls the multimedia connection cable bodies 4 later, thus preventing damage to the internal circuitry of the multimedia connection cable body 4.

[0021] As a further embodiment of the present invention, the storage box 1 is provided with two elastic ropes 26 inside, and the two elastic ropes 26 are located on both sides of the storage rod 11.

[0022] In this invention, after the multimedia connection cable body 4 is sequentially wound around the outer wall of the storage rod 11, the elastic ropes 26 on both sides can limit the position of the multimedia connection cable body 4, preventing the ends of the multimedia connection cable body 4 from becoming loose and thus causing it to fall off after being sequentially wound around the outer wall of the storage rod 11 (e.g.). Figure 6 As shown, the multimedia connector cable body 4 is limited by elastic cords 26 on both sides. The elasticity of the elastic cords 26 not only allows it to be used with multimedia connector cables of different thicknesses, but also the smoothness of the surface of the elastic cords 26 can prevent the elastic cords 26 from scraping against the surface of the multimedia connector cable body 4 when limiting it, thus avoiding damage to the surface of the multimedia connector cable body 4.

[0023] As a further embodiment of the present invention, a through hole is provided at the lower end of the outer wall of the storage rod 11, and wire take-up holes 5 are provided at the lower ends of both sides of the storage box 1. The upper surfaces of the two wire take-up holes 5 are rounded corners 6. The multimedia connection cable body 4 passes through the storage box 1 through the wire take-up holes 5, the wire ring 18 and the through hole.

[0024] The present invention avoids the problem that the right angles on both sides of the upper end face of the cable take-up hole 5 would damage the surface of the multimedia cable body 4 when the multimedia cable body 4 is wound upwards on the outer wall of the storage rod 11, by using rounded corners 6 on both sides of the upper end face of the cable take-up hole 5.

[0025] As a further embodiment of the present invention, baffles 8 are rotatably connected to both sides of the storage box 1. Both baffles 8 are located below the cable take-up hole 5. A first torsion spring 10 is fixedly installed between both sides of the two baffles 8 and the side wall of the storage box 1. Support plates 23 are fixedly installed on both sides of the inner wall of the storage box 1. Both support plates 23 are located below the cable take-up hole 5. A slider 24 is slidably connected to the top of both support plates 23. A first spring 25 is fixedly installed between the slider 24 and the support plate 23. A frame 7 is fixedly installed on the top of each slider 24. The frame 7 presses against the upper surface of the baffle 8. A pull ring 9 is fixedly installed on the lower surface of the baffle 8.

[0026] After the multimedia cable body 4 is wound up, the connectors at both ends of the multimedia cable body 4 will contact the frame 7. The frame 7 is slidably connected to the support plate 23 via a slider 24 fixed at the bottom. The frame 7 can be driven to slide from the winding hole 5 to the upper surface of the support plate 23. At this time, when the lower surface of the frame 7 separates from the upper surface of the baffle 8, the baffle 8 can automatically rotate counterclockwise (viewed from the front of the device) via the first torsion springs 10 fixed between its two sides and the side wall of the storage box 1, sealing the winding hole 5 (e.g., ...). Figure 2 and Figure 4 As shown, the frame 7 opens the baffle 8 by pressing. After the storage rod 11 has stored the multimedia connection cable body 4, the connectors at both ends of the multimedia connection cable body drive the frame 7 to slide into the storage box 1. This not only allows the baffle 8 to automatically close and seal the cable hole 5 to prevent dust from entering the storage box 1, but also allows the connectors at both ends of the multimedia connection cable to be simultaneously engaged with the frame 7 and stored inside the storage box 1. When the multimedia connection cable needs to be used, pulling the pull ring 9 on the lower end of the baffle 8 will cause the baffle 8 to rotate clockwise (viewed from the front of the device). At this time, the first spring 25, which is fixed between the slider 24 and the support plate 23, can automatically push the frame 7 to the initial position (as shown). Figure 4 As shown, the frame 7, through the rebound force of the first spring 25, can not only automatically push the frame 7 back to the initial position to press the upper surface of the baffle 8, but also automatically drive the connectors at both ends of the multimedia connector to move outside the storage box 1, making it convenient for staff to retrieve the connectors.

[0027] This invention, during the process of storing the multimedia cable body 4, causes the connectors at both ends of the multimedia cable body 4 to slide into the upper surface of the support plate 23, so that the baffle 8 automatically rotates to seal the cable take-up hole 5 by the rebound force of the first torsion spring 10. This not only prevents dust from entering the storage box 1 from the cable take-up hole 5, but also simultaneously retracts the connectors at both ends of the multimedia cable body 4 into the storage box 1, protecting the connectors.
