Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to the outer casing of a loose-leaf notebook with a quick-release mechanism featuring hinge rings. Background Technology

[0002] Loose-leaf notebooks, with their advantage of freely replaceable and reorganized paper, have become a common stationery item for students and working professionals. However, the traditional loose-leaf notebook covers rely on springs to control the opening and closing. After long-term use, the springs are prone to elasticity failure, leading to difficulty in opening and closing. In addition, many loose-leaf notebook covers are made of metal with tight snap-fit ​​connections, requiring effort to remove paper, which is very inconvenient. Some loose-leaf notebooks require the entire cover to be opened to take out or put in the inner pages, making the operation cumbersome. In order to meet users' core need for efficient loose-leaf replacement, a loose-leaf notebook cover with a quick-release structure of loose-leaf rings has emerged. Currently, the binder casing with a quick-release mechanism for hinge rings uses a threaded drive to achieve rapid hinge ring removal. The structure is precise and durable. The inner side of the casing has a symmetrical clamping mechanism, which consists of a fixed ring, a movable ring, and a transmission component. Rotating the outer main knob will drive the coaxial threaded shaft to rotate. Through the threaded engagement, the moving frame will move axially. The moving frame pulls the control frame and the connecting frame to transmit force, causing the movable frame to rotate around the movable shaft fixed to the casing, allowing the movable ring to separate from the fixed ring and form a gap. At this time, the hinge ring can be easily replaced. Rotating the main knob in the opposite direction will reset all components, and the movable ring and fixed ring will close and fix together again. This design abandons the traditional spring structure, avoids elastic failure, and balances stability and ease of operation. Currently, when the rings on the cover of a loose-leaf notebook are damaged, only the ring itself needs to be replaced, without discarding the entire cover. Combined with a wear-resistant and durable cover material, it can be reused for a long time, reducing usage costs and making it more economical and environmentally friendly. Most covers have rounded edges, so they won't feel uncomfortable when writing and support smooth writing across pages without affecting the user experience. However, the rings on these loose-leaf notebooks are mostly fixed with screws, requiring a screwdriver or other tools for disassembly, making quick disassembly and assembly difficult and causing inconvenience when replacing rings or organizing the pages. Therefore, a loose-leaf notebook cover with a quick-release ring structure is proposed to solve these problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a binder cover with a quick-release mechanism for the binder rings. It aims to improve the problem that in the prior art, the binder rings are fixed with screws, which requires the use of tools such as screwdrivers for disassembly, making quick disassembly and assembly impossible and causing inconvenience for replacing the rings or organizing the inner pages.

[0005] This utility model has the following beneficial effects: 1. In this utility model, pressing the card seat causes the connecting column and the fixing block to move downwards. The conical surface of the fixing block squeezes the wedge block to slide into the card slot, pushing the spring to compress. The limiting column guides the sliding trajectory. After the fixing block slides past, the spring pushes the wedge block to reset and abut against its top, realizing the locking function. Pressing the card seat again causes the connecting column to move the fixing block and the slider downwards. The slider is restricted by the positioning block and abuts against its bottom, squeezing the wedge block to slide again. Pulling the card seat upwards causes the fixing block to disengage, realizing the quick separation function.

[0006] 2. In this utility model, the support rod is rotated outward to drive the rotating column to rotate synchronously. The rotating column drives the suction cup to adapt to the placement surface direction. The support rod adjusts the support angle around the connecting rod. The suction cup adheres to different inclined contact surfaces with the help of adsorption force to achieve stable support function. The support rod is rotated in the opposite direction to drive the rotating column and suction cup to move together and be stored in the groove to achieve the support rod storage function.

[0009] 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. Example

[0010] The binder cover with a quick-release mechanism featuring hinged rings is shown in the reference. Figures 1 to 3 The device includes a protective shell 1, which is made of high-strength engineering plastic and integrally injection molded, possessing excellent impact resistance and wear resistance. A connecting plate 3 is fixedly connected to one side of the protective shell 1, and a protective shell 2 is fixedly connected to the other side of the connecting plate 3. The protective shell 1 and the protective shell 2 are connected by the connecting plate 3. The material of the protective shell 2 is the same as that of the protective shell 1. A support mechanism 5 is provided at the bottom of the protective shell 2. The support mechanism 5 can flexibly adjust its angle according to the usage scenario to ensure the stability of the entire device when placed. A quick-release mechanism 4 is provided on the inner wall of the connecting plate 3, allowing the hinge rings to be quickly released without the need for additional tools. Disassembly and assembly can be completed quickly. The top of the connecting plate 3 is movably connected to the card seat 6. The card seat 6 is connected to the connecting plate 3 through the quick-release mechanism 4. The quick-release mechanism 4 allows the card seat 6 to be quickly disassembled. The inner wall of the card seat 6 is rotatably connected to the retaining ring 7. The inner wall of the card seat 6 is rotatably connected to the retaining ring 7 for fixing the component through the bearing. The retaining ring 7 is composed of two semi-circular rings. It is opened and closed by a hinge on one side and a latch on the other side. When closed, it can form a complete circle. The retaining ring 7 is made of stainless steel. This material not only has excellent corrosion resistance and rust resistance, but also has high hardness and toughness. It can withstand a certain amount of external impact without easily deforming. Specifically, the protective shell 1 and the protective shell 2, made of the same high-strength material, protect the writing paper installed inside. The support mechanism 5 adjusts the angle to change the overall placement of the device, providing a stable reference for subsequent writing. The quick-release mechanism 4 can drive the card holder 6 to quickly separate or reset along the connecting plate 3, realizing convenient disassembly and assembly of the card holder 6. The bearing on the inner wall of the card holder 6 provides rotational support for the retaining ring 7. The retaining ring 7 completes the opening and closing action to fix the target component through the cooperation of hinge rotation and locking. The stainless steel material ensures that it is not easily deformed during opening and closing.

[0011] The quick-release mechanism 4 includes two wedge-shaped blocks 46, which are symmetrically distributed inside the connecting plate 3. The outer walls of the two wedge-shaped blocks 46 are slidably connected to the inner wall of the connecting plate 3. The outer walls of the two wedge-shaped blocks 46 are precisely matched with the reserved slides on the inner wall of the connecting plate 3 to achieve smooth sliding. A connecting post 41 is fixedly connected to the bottom of the card holder 6. A positioning block 43 is fixedly connected to the outer wall of the connecting post 41. The positioning block 43 is fixed at a position close to the card holder 6. A slider 44 is slidably connected to the outer wall of the connecting post 41. The positioning block 43 controls the sliding range of the slider 44. The bottom of the connecting column 41 is fixedly connected to a fixing block 45. The inclined surface of the fixing block 45 fits against the inclined surface of the wedge block 46, allowing the fixing block 45 to slide over the wedge block 46. The wedge block 46 abuts against the top of the fixing block 45. The inner wall of the connecting plate 3 has two slots 42, which are symmetrically distributed. The inner wall of the slots 42 is fixedly connected to a reset component 47, which provides reset power to the wedge block 46. The outer wall of the wedge block 46 is slidably connected to the inner wall of the slots 42. The fixing block 45 is shaped like a flat-topped cone. Specifically, pressing the card holder 6 causes the fixing block 45 to move downwards, and its conical surface presses against the symmetrically distributed wedge blocks 46, causing the wedge blocks 46 to slide into the card slot 42. After the fixing block 45 slides past the wedge blocks 46, the reset component 47 releases its elastic force to push the wedge blocks 46 back to their original position. The wedge blocks 46 abut against the top of the fixing block 45 to lock it in place. If the card holder 6 needs to be removed, press the card holder 6 again, and the slider 44 moves downwards synchronously with the fixing block 45 on the connecting post 41. Restricted by the positioning block 43, the slider 44 slides past the wedge blocks 46, causing the wedge blocks 46 to slide into the card slot 42 again. Pulling the card holder 6 upwards can quickly separate the card holder 6 from the connecting plate 3.

[0012] The reset assembly 47 includes a limiting post 472, which is fixedly connected to the inner wall of the slot 42. The limiting post 472 restricts the movement of the wedge block 46. A spring 471 is sleeved on the outer wall of the limiting post 472. The spring 471 provides the wedge block 46 with the power to rebound and reset. One side of the spring 471 is fixedly connected to one side of the wedge block 46, and the other end of the spring 471 is fixedly connected to the inner wall of the slot 42. One side of the limiting post 472 is slidably connected to the inner wall of the wedge block 46. The cross-section of the wedge block 46 is trapezoidal, and the inclined surface of the wedge block 46 matches the inclined surface of the fixing block 45. Specifically, the fixed block 45 moves down, its inclined surface pressing against the wedge block 46. The wedge block 46 slides inward along the slot 42, simultaneously pushing the spring 471 to compress and store force. The limiting post 472 guides the wedge block 46 to maintain a stable sliding trajectory and avoid deviation. After the fixed block 45 slides past, the compressed spring 471 releases its elasticity, pushing the wedge block 46 to slide back and reset. The limiting post 472 limits its maximum stroke to ensure that the wedge block 46 accurately abuts against the top of the fixed block 45. The trapezoidal structure of the wedge block 46 fits the inclined surface of the fixed block 45, ensuring the smooth transmission of force during the pressing and resetting process.

[0013] Reference Figure 1 and Figure 4 The support mechanism 5 includes two connecting rods 52, which are symmetrically distributed and fixedly connected to the inner wall of the second protective shell 2. The outer walls of the two connecting rods 52 are rotatably connected to support rods 53. A rotating column 54 is rotatably connected to one side of the support rod 53, and a suction cup 55 is fixedly connected to one side of the rotating column 54. The angle of the suction cup 55 can be adjusted by the rotating column 54. A groove 51 is opened at the bottom of the second protective shell 2. The two connecting rods 52 are fixedly connected to the inner wall of the groove 51. By rotating the connecting rods 52, the connecting rods 52 can be stored inside the groove 51. The suction cup 55 is rotatably connected to the bottom of the support rod 53, and the suction cup 55 provides stability for the support rod 53. Specifically, the support rod 53 is rotated around the connecting rod 52 to expand outward from the groove 51. The rotating column 54 adjusts the angle of the suction cup 55 to match the contact surface. The suction force of the suction cup 55 ensures stability. The support rod 53 can be rotated into the groove 51 to store it, realizing the flexible switching between support and storage of the support rod 53.

[0014] The implementation principle of this application embodiment is as follows: Pressing the card seat 6 causes the connecting column 41 to move the fixing block 45 downward, and its conical wedge block 46 is squeezed, causing the wedge block 46 to slide into the card slot 42, pushing the spring 471 to compress and store force. The limiting column 472 guides the wedge block 46 to maintain a stable sliding trajectory. After the fixing block 45 slides past the wedge block 46, the spring 471 releases its elastic force to push the wedge block 46 to reset, so that the wedge block 46 abuts against the top of the fixing block 45 to lock. If the card seat 6 needs to be removed, press the card seat 6 again, and the slider 44 moves down synchronously with the fixing block 45 on the connecting column 41. Restricted by the positioning block 43, the slider 44 abuts against the bottom of the positioning block 43 and no longer slides. The slider 44 slides past the wedge block 46, causing the wedge block 46 to slide into the card slot 42 again, pulling the card seat 6 upward, and causing the fixing block 45 to disengage from the inside of the connecting plate 3, thereby achieving rapid separation of the card seat 6 and the connecting plate 3. Rotate the support rod 53 outward to disengage it from the groove 51 and unfold it. Rotate the support rod 53 around the connecting rod 52 to adjust the support angle. The rotating column 54 rotates synchronously with the support rod 53, causing the bottom suction cup 55 to adapt to the placement surface direction. The rotating column 54 allows the suction cup 55 to flexibly fit the contact surface with different inclinations. The suction force enhances the stability of the support. When the support is not needed, rotate the support rod 53 in the opposite direction to store it together with the rotating column 54 and the suction cup 55 into the groove 51.
