Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a torsion spring type three-dimensional hinge. Background Technology

[0002] Hinges, also known as hinges, are often two-fold components that connect two parts of an object and allow them to move. Currently, hydraulic hinges have complex structures, leading to high costs.

[0003] Existing hydraulic hinges rely on precision hydraulic cylinders and sealing systems, requiring the machining of multiple micro-oil passages. The manufacturing process is complex, the material costs are high (such as copper hydraulic cylinder bodies), and the assembly precision requirements are stringent.

[0004] Difficult to repair and maintain:

[0005] Once the hydraulic system leaks oil or the damping fails, the entire hydraulic module must be replaced; partial repairs are not possible. Once the seals age, disassembly becomes difficult, and it is hard for non-professionals to operate.

[0006] Over-reliance on hydraulics for functionality:

[0007] The closed buffer is entirely achieved by hydraulic oil damping. In low-temperature environments, the viscosity of hydraulic oil changes greatly (such as the oil solidifying below -10℃), which can lead to buffer failure or uneven speed. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a torsion spring type three-dimensional hinge, which solves the problems of high cost, difficult maintenance, and excessive reliance on hydraulic systems in current hydraulic hinges.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a torsion spring type three-dimensional hinge, including a first mounting base and a second mounting base, a first connecting block and a second connecting block are fixedly installed in the inner cavity of the first mounting base respectively, and a first inclined groove is opened on the opposite side of the first connecting block and the second connecting block. A first sliding rod is slidably sleeved in the inner cavity of the first inclined groove. An installation rod and a first connecting rod are respectively sleeved between the first connecting block and the second connecting block, and a torsion spring is sleeved on the surface of the installation rod. A first connecting plate is fixedly installed at the bottom of the first connecting block and the second connecting block.

[0010] The inner cavity of the second mounting base is fixedly installed with a third connecting block and a fourth connecting block, and a second inclined groove is opened on the opposite side of the third connecting block and the fourth connecting block. A second sliding rod is slidably sleeved in the inner cavity of the second inclined groove. A buffer cylinder is provided in the inner cavity of the fourth connecting block, and a second connecting rod is sleeved between the first connecting block and the second connecting block, and the surface of the second connecting rod extends into the inner cavity of the fourth connecting block.

[0011] The surfaces of the second connecting rod, the first sliding rod, the second sliding rod, and the first connecting rod are respectively rotatably fitted with the first leaf and the second leaf through bearings, and a shaft core is installed between the first leaf and the second leaf through bearings.

[0012] Preferably, the buffer cylinder is inclined and abuts against one end of the first leaf, and one end of the buffer cylinder extends to the outside of the inner wall of the fourth connecting block.

[0013] Preferably, the two ends of the torsion spring are hooked onto the surface of the first sliding rod near the edges of the first connecting block and the second connecting block.

[0014] Preferably, the middle extension end of the torsion spring abuts against the first connecting plate.

[0015] Preferably, the second sheet is located inside the cavity of the first sheet.

[0016] Preferably, a second connecting plate is fixedly installed at the bottom of the third connecting block and the fourth connecting block.

[0017] This invention provides a torsion spring type three-dimensional hinge. Compared with the prior art, it has the following advantages:

[0018] This torsion spring three-dimensional hinge generates a torsional force by rotating the first and second leaf plates. The first leaf plate, rotating on the second connecting rod, presses against the buffer cylinder, and the torsion spring automatically resets through its elastic force. Compared with hydraulic hinges, this hinge features a simpler structure, requires no complex design, is easy to maintain, avoids buffer failure or uneven speed due to low temperature hydraulic oil, and has lower production costs.

[0029] 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.

[0030] Please see Figures 1-7This utility model provides a technical solution: a torsion spring type three-dimensional hinge, including a first mounting base 1 and a second mounting base 2. A first connecting block 11 and a second connecting block 12 are fixedly mounted in the inner cavity of the first mounting base 1, and a first inclined groove 13 is formed on the opposite side of the first connecting block 11 and the second connecting block 12. A first sliding rod 16 is slidably sleeved in the inner cavity of the first inclined groove 13. An installation rod 15 and a first connecting rod 17 are respectively sleeved between the first connecting block 11 and the second connecting block 12, and a torsion spring 5 is sleeved on the surface of the installation rod 15. The two ends of the torsion spring 5 are hooked near the first connecting block. On the surface of the first sliding rod 16 at the edge of the first connecting block 11 and the second connecting block 12, a first connecting plate 14 is fixedly installed at the bottom of the first connecting block 11 and the second connecting block 12. The middle extension end of the torsion spring 5 abuts against the first connecting plate 14. The inner cavity of the second mounting base 2 is fixedly installed with the third connecting block 21 and the fourth connecting block 22 respectively. The bottom of the third connecting block 21 and the fourth connecting block 22 is fixedly installed with the second connecting plate 24. The opposite sides of the third connecting block 21 and the fourth connecting block 22 are provided with a second inclined groove 23. The inner cavity of the second inclined groove 23 is slidably sleeved with the second sliding rod 26. The fourth connecting block... A buffer cylinder 8 is installed in the inner cavity of the fourth connecting block 22. The buffer cylinder 8 is inclined and abuts against one end of the first leaf 3. One end of the buffer cylinder 8 extends to the outer wall of the fourth connecting block 22. A second connecting rod 25 is sleeved between the first connecting block 11 and the second connecting block 12, and the surface of the second connecting rod 25 extends into the inner cavity of the fourth connecting block 22. One end of the first leaf 3 rotates on the second connecting rod 25, and the other end rotates on the first sliding rod 16, driving the first sliding rod 16 to move in the first inclined groove 13. One end of the second leaf 4 rotates on the first connecting rod 17. The first end moves while the other end rotates on the second sliding rod 26, causing the second sliding rod 26 to move in the second inclined groove 23, thereby causing the first leaf 3 and the second leaf 4 to rotate. The first inclined groove 13 and the second inclined groove 23 are used to change the distance between the first mounting base 1 and the second mounting base 2 when the first leaf 3 and the second leaf 4 rotate, and to generate a torsional force on the torsion spring 5. The first leaf 3, which rotates on the second connecting rod 25, will squeeze the buffer cylinder 8. The torsion spring 5 achieves automatic reset through elasticity, while the buffer cylinder 8 buffers, so that the first leaf 3 and the second leaf 4 slowly and automatically reset.

[0031] The surfaces of the second connecting rod 25, the first sliding rod 16, the second sliding rod 26, and the first connecting rod 17 are respectively rotatably sleeved with the first sheet 3 and the second sheet 4 via bearings 7. The second sheet 4 is located in the inner cavity of the first sheet 3, and a shaft core 6 is installed between the first sheet 3 and the second sheet 4 via bearings 7. The first sheet 3 and the second sheet 4 are connected via shaft core 6, and the first sheet 3 and the second sheet 4 can rotate via bearings 7.

[0032] Please see Figures 8-9This refers to the working state where the hinge is fully closed and rotated 90 degrees.

[0033] During operation or use, the first mounting base 1 and the second mounting base 2 are first installed on the bathroom door and the door frame respectively. When the bathroom door is rotated, the first leaf 3 and the second leaf 4 will rotate relative to each other through the connection of the shaft core 6. One end of the first leaf 3 rotates on the second connecting rod 25, and the other end rotates on the first sliding rod 16, driving the first sliding rod 16 to move in the first inclined groove 13. At the same time, the torsion spring 5 is pulled, and the middle extension end of the torsion spring 5 will tightly abut against the first connecting plate 14, causing the torsion spring 5 to generate a torsional force. The first leaf 3 rotating on the second connecting rod 25 will squeeze the buffer cylinder 8, while one end of the second leaf 4 rotates on the first connecting rod 17, and the other end rotates on the second connecting rod 18. The sliding rod 26 rotates, causing the second sliding rod 26 to move in the second inclined groove 23, thereby causing the first leaf 3 and the second leaf 4 to rotate. When the first mounting seat 1 or the second mounting seat 2 is released, the torsion spring 5 will reset under the elastic force, thereby automatically driving the first sliding rod 16 to reset, which in turn drives the first leaf 3 and the second leaf 4 to reset. At the same time as resetting, the buffer cylinder 8 provides buffering, so that the first leaf 3 and the second leaf 4 slowly and automatically reset. Compared with hydraulic hinges, the elastic force of the torsion spring 5 and the buffering setting of the buffer cylinder 8 are simpler in structure, do not require complex structure, are easy to maintain, and will not cause buffer failure or uneven speed due to low temperature of hydraulic oil. In addition, the production cost is lower.
