Description

Technical Field

[0001] This utility model relates to the field of metal hinge technology, specifically a multi-directional positioning metal hinge structure. Background Technology

[0002] Metal hinges are the core connecting components that enable objects to rotate and open. They typically consist of two metal plates and an intermediate pivot assembly. The rotational characteristics of the pivot allow the connected components to open and close flexibly. They are often made of stainless steel, cold-rolled steel, or aluminum alloy, combining high strength and corrosion resistance. They can withstand the wear and pressure from long-term opening and closing, effectively extending their service life.

[0003] In actual use, traditional metal hinges often require fixing the positions of connected components after rotation to achieve hinge stability. However, this method is limited by structural design or installation methods, making it difficult for operators to quickly and easily rotate and fix some components. Consequently, the hinge itself may not be able to complete rotation and fixation in a timely manner, significantly impacting operational efficiency. Furthermore, traditional metal hinges have a significantly limited range of positioning directions, making it impossible to flexibly rotate and position the hinge and its connected components from multiple angles and positions. After connecting the connecting plates at both ends of the hinge to external fixing components and rotating components (such as the door body and door frame) respectively, and adjusting the angle between the rotating component and the fixing component by pushing the rotating component, it is impossible to quickly fix it at different angles. This makes it difficult to meet the rotation angle positioning requirements between the fixing and rotating components in different usage scenarios, directly leading to a significant reduction in the applicability of traditional metal hinges. In scenarios requiring flexible angle adjustment or quick fixation, this not only increases the difficulty of operation but may also cause problems such as loosening of components and safety hazards due to inaccurate positioning, seriously affecting its application effect and promotion value in various scenarios. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a multi-directional positioning metal hinge structure. This addresses the current problem in the actual use of metal hinges. Traditional metal hinges, after rotation, often require fixing the positions of the connected components to achieve rotational fixation. However, this fixing method is limited by the structural design or installation method of some connected components, making it difficult for operators to quickly and conveniently rotate and fix them. Consequently, the metal hinge cannot be rotated and fixed in a timely manner, greatly affecting operational efficiency. Furthermore, the positioning direction range of traditional metal hinges is significantly limited, unable to be positioned from multiple angles... The multi-position flexible rotation and positioning of metal hinges and their connecting components, after connecting the connecting plates at both ends of the hinge to the external fixing and rotating components respectively, and adjusting the angle between the rotating and fixing components by pushing the rotating component, cannot quickly fix it for different angles. Therefore, it is difficult to meet the rotation angle positioning requirements between the fixing and rotating components in different usage scenarios. This directly leads to a significant reduction in the applicability of traditional metal hinges. In scenarios that require flexible angle adjustment or quick fixation, it not only increases the difficulty of operation, but may also cause problems such as loosening of components and safety hazards due to inaccurate positioning. These technical problems seriously affect its application effect and promotion value in various scenarios.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a multi-directional positioning metal hinge structure is designed, including a fixed shaft, a first hinge plate and a second hinge plate. A first rotating sleeve and a second rotating sleeve are respectively rotatably sleeved on both sides of the outer wall of the fixed shaft. A connecting block is fixedly installed on the outer wall of each first rotating sleeve and second rotating sleeve. The side ends of every two sets of connecting blocks are respectively fixedly connected to the outer walls of the first hinge plate and the second hinge plate. Both ends of the fixed shaft are rotatably sleeved with fixed blocks, and the side walls of the two sets of fixed blocks are respectively fixedly connected to the outer walls of the first rotating sleeve and the second rotating sleeve. Each fixed block is provided with a pressing mechanism and a reset mechanism on its outer side. Both ends of the outer wall of the fixed shaft are provided with limit mechanisms, and the limit mechanisms and the pressing mechanism are connected in a transmission manner.

[0006] Preferably, there are two sets of the first rotating sleeve and the second rotating sleeve, and the first rotating sleeve and the second rotating sleeve are alternately rotated and sleeved on the outer wall of the fixed shaft.

[0007] Preferably, the pressing mechanism includes a transmission plate and a pressing plate. Each fixed block has a support plate fixedly installed at both ends of its side wall. A rotating shaft is rotatably installed through a bearing at the side ends of every two sets of support plates. A transmission plate is fixedly sleeved at the middle of the outer side of each rotating shaft. A pressing plate is fixedly installed at the side end of each transmission plate.

[0008] Preferably, the limiting mechanism includes a limiting block, and a limiting block is fixedly installed on the outer side wall of each of the pressing plates. Mounting blocks are fixedly installed at both ends of the side wall of the fixed shaft, and the limiting block is movably located outside the mounting block.

[0009] Preferably, the mounting block has several sets of limiting slots equidistantly spaced on its outer side, and the side end of the limiting block is slidably inserted into the limiting slot.

[0010] Preferably, the reset mechanism includes a push spring reset torsion spring, and a connecting column is fixedly installed on the outer wall of each fixed block and the side wall of the pressure plate, with a push spring sleeved between the outer walls of every two sets of connecting columns.

[0011] Preferably, a fixing tube is fixedly installed on the outer wall of each support plate, and the side end of the rotating shaft extends rotatably into the interior of the fixing tube. A connecting shaft is rotatably installed inside each fixing tube via a bearing, and the side end of the connecting shaft and the side end of the rotating shaft are fixedly connected.

[0012] Preferably, each of the rotating shafts is movably fitted with a reset torsion spring on its outer wall, and the two ends of the reset torsion spring abut against the outer wall of the rotating shaft and the inner wall of the fixed tube, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model involves rotatably connecting a first rotating sleeve and a second rotating sleeve to the outside of a fixed shaft, and connecting two sets of fixing blocks to the first and second rotating sleeves respectively. This allows the first and second hinge plates to be connected to the external rotating and fixing components respectively. Since the fixing component itself cannot move, the second hinge plate also cannot rotate relative to the outer wall of the fixed shaft. At this point, combined with the locking and limiting effect of the limiting block connected to the second hinge plate on the fixed shaft, this allows for... The fixed shaft is secured in a snap-fit ​​manner. When the fixed and rotating parts are rotated, the fixed shaft itself cannot rotate. This ensures that when the first hinge plate needs to be positioned after rotation, the fixed shaft can provide a corresponding abutment and limiting force. Subsequently, when the operator needs to adjust the included angle between the two hinge plates, they only need to press down the pressure plate, causing it to move towards the outer wall of the fixed block. This will drive the transmission plate to rotate around the rotating shaft as the center, so that as the side end of the transmission plate rises, it drives the limiting block to move synchronously from the limiting slot. When the internal mechanism is lifted and moved out, the limiting slot loses its resistance to the limiting block. Simultaneously, the first hinge plate and the first rotating sleeve rotate on the outer wall of the fixed shaft, allowing the limiting block at the top of the fixed block to rotate synchronously. This allows for adjustment of the position of the limiting block, thereby adjusting the rotation angle between the rotating and fixed components. When positioning the fixed and rotating components, i.e., the first and second hinge plates, is required, the operator simply needs to release the pressure plate. After the downward pressure is applied, combined with the reverse pushing action of the push spring, the pressure plate and transmission plate can return to their original positions, while the transmission plate and the limit block move down synchronously. The limit block is simultaneously engaged with the limit slots evenly distributed on the outside of the mounting block. With the rotational limiting action of the limit slots on the limit block and the fixing limiting action of the fixed shaft on the transmission plate, the rotational positioning of the hinge plate connected to the rotating part can be completed. This improves the stability of the hinge plate and external components, and enables multi-directional positioning of the entire hinge.

[0014] 2. This utility model, by setting a fixed tube on the outside of the support plate and connecting the reset torsion spring and the rotating shaft through the connecting shaft, enables the transmission plate to be pressed to rotate and adjust the hinge between the first and second hinge plates, i.e., to simultaneously rotate and adjust the position of the limiting block. After releasing the pressure on the transmission plate, the reset torsion spring provides the torque required for the transmission plate and the limiting block to return to their original rotation, further improving the speed at which the limiting block is inserted into the limiting slot and simultaneously improving the stability of the first and second hinge plates during use.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A multi-directional positioning metal hinge structure, see [link / reference] Figures 1 to 4 A first rotating sleeve 11 and a second rotating sleeve 12 are respectively rotatably sleeved on both sides of the outer wall of the fixed shaft 1. A connecting block 13 is fixedly installed on the outer wall of each first rotating sleeve 11 and second rotating sleeve 12. The side ends of each pair of connecting blocks 13 are fixedly connected to the outer walls of the first hinge plate 14 and the second hinge plate 15, respectively. The first hinge plate 14 and the second hinge plate 15 are respectively located on both sides of the outside of the fixed shaft 1. There are two sets of first rotating sleeves 11 and second rotating sleeves 12. The first rotating sleeves 11 and the second rotating sleeves 12 are alternately rotatably sleeved on the outer wall of the fixed shaft 1. The first rotating sleeve 11 is connected to the first hinge plate 14, and the second rotating sleeve 12 is connected to the second hinge plate 15.

[0017] Specifically, as shown in Figures 1-2, both ends of the sidewall of the fixed shaft 1 are rotatably sleeved with fixed blocks 2, and the sidewalls of the two sets of fixed blocks 2 are respectively fixedly connected to the outer walls of the first rotating sleeve 11 and the second rotating sleeve 12. Each fixed block 2 is provided with a pressing mechanism and a resetting mechanism on its outer side. The pressing mechanism includes a transmission plate 23 and a pressing plate 26. Each end of the sidewall of the fixed block 2 is fixedly installed with a support plate 21. A rotating shaft 22 is rotatably installed through a bearing at the side ends of every two sets of support plates 21. A transmission plate 23 is fixedly sleeved at the middle of the outer side of each rotating shaft 22. A pressing plate 26 is fixedly installed at the side end of each transmission plate 23.

[0018] Furthermore, referring to Figures 1-2, both ends of the outer wall of the fixed shaft 1 are provided with limiting mechanisms. The limiting mechanisms include limiting blocks 27. Each pressing plate 26 has a limiting block 27 fixedly installed on its outer wall. Both ends of the side wall of the fixed shaft 1 are fixedly installed with mounting blocks 28. The limiting blocks 27 are movably located outside the mounting blocks 28. Several sets of limiting slots 29 are equidistantly opened on the outside of the mounting blocks 28. The side ends of the limiting blocks 27 are slidably inserted into the limiting slots 29.

[0019] It is worth noting that, referring to Figures 1-2, the reset mechanism includes a push spring 25 and a reset torsion spring 32. Each fixed block 2 and the side wall of the pressure plate 26 are fixedly installed with a connecting column 24. A push spring 25 is sleeved between the outer walls of every two sets of connecting columns 24, and the side end of the push spring 25 is inserted into the inside of the connecting column 24, while the whole is movably sleeved between the outer walls of the two sets of connecting columns 24. Each support plate 21 is fixedly installed with a fixed tube 3, and the side end of the rotating shaft 22 extends rotatably into the inside of the fixed tube 3. Each fixed tube 3 is rotatably installed with a connecting shaft 31 through a bearing, and the side end of the connecting shaft 31 is fixedly connected to the side end of the rotating shaft 22. Each rotating shaft 22 is movably sleeved with a reset torsion spring 32, and the two ends of the side of the reset torsion spring 32 abut against the outer wall of the rotating shaft 22 and the inner wall of the fixed tube 3, respectively.

[0020] During operation, when the hinge structure consisting of the first hinge plate 14, the second hinge plate 15, and the fixed shaft 1 needs to be used, the first hinge plate 14 and the second hinge plate 15 are connected to the external rotating and fixing components respectively by passing bolts through the connecting holes inside the hinge plates. Alternatively, the installation positions of the first hinge plate 14 and the second hinge plate 15 can be interchanged according to actual needs, as long as the two hinge plates are connected to the fixing and rotating components respectively. After the overall assembly of the hinge is completed, when the hinge structure needs to be rotated and adjusted, the outer wall of the fixed shaft 1... The first rotating sleeve 11 and the second rotating sleeve 12 are respectively rotatably sleeved on both sides, and the outer walls of the first rotating sleeve 11 and the second rotating sleeve 12 are fixedly connected to the hinge plate through the connecting block 13. At the same time, the two sets of fixing blocks 2 are fixed to the outer walls of the first rotating sleeve 11 and the second rotating sleeve 12 respectively. Therefore, when the operator applies a rotational force to the first hinge plate 14, the first hinge plate 14 will drive the corresponding first rotating sleeve 11 to rotate on the outer wall of the fixed shaft 1, and then synchronously drive the fixing block 2 connected to the first hinge plate 14 to rotate at the top of the side wall of the fixed shaft 1, providing a basic transmission path for the multi-directional rotation of the hinge. Before rotational adjustment, the rotational constraint of the limiting mechanism on the fixed block 2 and the connecting plate must be released. At this time, the operator needs to apply downward pressure to the pressing mechanism connected to the first hinge plate 14, so that the pressing plate 26 moves towards the outer wall of the fixed block 2. Since the pressing plate 26 is fixedly connected to the transmission plate 23, and the transmission plate 23 is rotatably mounted between the support plates 21 through the rotating shaft 22, the downward movement of the pressing plate 26 will drive the transmission plate 23 to rotate around the rotating shaft 22. As the transmission plate 23 rotates, its side end will rise upward, and the limiting block 27 fixed to the outer wall of the pressing plate 26 will move synchronously with the transmission plate 23, rising and moving out from the limiting slot 29 on the outside of the mounting block 28. When the limiting block 27 is completely disengaged from the limiting slot 29, the limiting... The abutting and limiting force of the locking slot 29 on the limiting block 27 disappears, and the fixed block 2 and the first rotating sleeve 11 connected to it obtain free rotation space on the fixed shaft 1. At this time, since the second hinge plate 15 is connected to the fixing member, the fixing member itself cannot rotate, which in turn causes the second rotating sleeve 12 connected to the second hinge plate 15 to also be unable to rotate synchronously on the outer wall of the fixed shaft 1. Consequently, the limiting block 27, which is connected to the second rotating sleeve 12, is still inserted from the bottom end of the fixed shaft 1 into the corresponding limiting slot 29, abutting and limiting the fixed shaft 1 itself so that it cannot rotate. Only when the rotating member connected to the first hinge plate 14 rotates can the first rotating sleeve 11 rotate flexibly to achieve multi-angle adjustment. After the rotating component is adjusted to the target position, it needs to be positioned and fixed by the cooperation of the reset mechanism and the limit mechanism. On the one hand, when the operator releases the downward pressure on the pressure plate 26, the spring 25 is pushed to release its elastic potential energy, generating a reverse pushing force, which pushes the pressure plate 26 away from the fixed block 2, thereby driving the transmission plate 23 to rotate in the opposite direction and reset. On the other hand, the reset torsion spring 32, which is movably sleeved on the outer wall of the rotating shaft 22, has its two ends abutting against the outer wall of the rotating shaft 22 and the inner wall of the fixed tube 3, respectively. At this time, the reset torsion spring 32... Releasing the torque, the auxiliary transmission plate 23 rotates rapidly in the opposite direction around the rotating shaft 22, further accelerating the reset process of the transmission plate 23 and the limiting block 27. Under the dual action of the pushing spring 25 and the reset torsion spring 32, the limiting block 27 moves down quickly and precisely engages with the limiting slots 29 evenly distributed on the outside of the mounting block 28. Since the limiting slots 29 form a rotational constraint on the limiting block 27, the rotation of the fixing block 2 is restricted, fixing the first hinge plate 14 in the target position and completing multi-directional positioning.
