Technical Field

[0001] This utility model relates to the field of hinges, specifically a hinge that is easy to position. Background Technology

[0002] Hinges are a common type of hardware, mainly used to connect doors, windows, cabinets, and other objects, allowing them to open and close smoothly. They are typically made of metal, are sturdy and durable, and are easy to install. Common types of hinges include ordinary hinges, spring hinges, and hydraulic hinges, suitable for different applications, and are indispensable small parts in furniture and construction.

[0003] One existing type of hinge that is easy to position can be found in the bearing hinge with application number CN202021180051.4, which includes a first hinge plate, a second hinge plate, and a hinge shaft. The first hinge plate and the second hinge plate are rotatably connected by the hinge shaft. The key feature is that a bearing is installed at the connection between the first hinge and the second hinge, and the hinge shaft is rotatably connected to the bearing. By installing a bearing on the hinge, the mechanical friction between the hinge shaft and the hinge plate can be converted into roller friction, which effectively extends the service life of the hinge. Furthermore, the bearing configuration can effectively improve the lubrication of the hinge rotation.

[0004] The aforementioned device does not include a component for positioning. Since the hinge can be rotated by a slight external force during use, it cannot be used to position the door. A slight external force can move the door. Therefore, a hinge that is easy to position is proposed to address the above problem. Utility Model Content

[0005] To overcome the shortcomings of existing technology, the existing devices do not have a component for positioning. Since the hinge can be rotated by a slight external force during use, it is impossible to rely on the hinge to position the door during use. The problem of the door being moved by a slight external force is addressed by this invention, which proposes a hinge that is easy to position.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the hinge that is easy to position according to this utility model includes a device base; the top end of the device base is fixedly connected to the bottom end of the first main body, a second main body is provided at the rear position of the device base, the top end of the second main body is provided with a storage groove, and a positioning mechanism is provided between the first main body and the second main body.

[0007] The positioning mechanism includes a movable positioning rod, which is also located on the left and right sides of the second main body. One end of the movable positioning rod passes through the second main body and reaches the storage slot opened inside the second main body. The other end of the movable positioning rod is fixedly connected to the movable plate. A fixed sleeve block is sleeved on the outside of the movable positioning rod, and the movable positioning rod is slidably connected to the fixed sleeve block.

[0008] Preferably, the front and rear ends of the fixed sleeve block are also provided with fixed support rods, and the side end of the fixed sleeve block is fixedly connected to one end of the fixed support rod, while the other end of the fixed support rod is fixedly connected to the outer side of the second main body.

[0009] Preferably, a return spring is sleeved on the outer side of the movable positioning rod, one end of the return spring is fixedly connected to the fixed sleeve block, and the other end of the return spring is fixedly connected to the movable plate.

[0010] Preferably, fixed guide rods are also provided on the left and right sides near the lower position of the second main body, and the side end of the second main body is fixedly connected to one end of the fixed guide rod.

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 scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a hinge that is easy to position includes a device base 1; the top end of the device base 1 is fixedly connected to the bottom end of the first body 2, and a second body 3 is provided at the rear of the device base 1. The top end of the second body 3 is provided with a storage groove 20, and a positioning mechanism is provided between the first body 2 and the second body 3.

[0024] The positioning mechanism includes a movable positioning rod 10, which is also set on the left and right sides of the second main body 3. One end of the movable positioning rod 10 passes through the second main body 3 and reaches the storage slot 20 opened inside the second main body 3. The other end of the movable positioning rod 10 is fixedly connected to the movable plate 11. A fixed sleeve block 12 is sleeved on the outside of the movable positioning rod 10, and the movable positioning rod 10 is slidably connected to the fixed sleeve block 12. The movable positioning rod 10 has a circular design, and both the upper and lower ends of one end of the movable positioning rod 10 are designed with bevels.

[0025] During operation, when the rotating plate 18 reaches the inside of the storage slot 20, it contacts the movable positioning rod 10. Since both the upper and lower ends of the movable positioning rod 10 are designed with bevels, the rotating plate 18 contacts the movable positioning rod 10 and the rotating plate 18 continues to move into the storage slot 20 at the same time, which will squeeze the movable positioning rod 10 to move outward. When the movable positioning rod 10 moves outward, it will move outward along the inside of the second main body 3. At the same time, the movable positioning rod 10 drives the moving plate 11 to move outward. When the movable positioning rod 10 moves outward, it will move outward along the inside of the fixed sleeve block 12.

[0026] Furthermore, fixed support rods 13 are also provided at the front and rear ends of the side of the fixed sleeve block 12, and one end of the fixed support rod 13 is fixedly connected to the side of the fixed sleeve block 12, and the other end of the fixed support rod 13 is fixedly connected to the outside of the second main body 3. The fixed support rod 13 is a round rod design.

[0027] During operation, the fixed support rod 13 is used to fix and support the position of the fixed sleeve block 12.

[0028] Furthermore, a return spring 14 is sleeved on the outside of the movable positioning rod 10. One end of the return spring 14 is fixedly connected to the fixed sleeve block 12. The fixed sleeve block 12 is circular in design, and the other end of the return spring 14 is fixedly connected to the movable plate 11.

[0029] During operation, the movable plate 11 moves outward, which will pull the return spring 14 to extend.

[0030] Furthermore, fixed guide rods 15 are also provided on the left and right sides of the second main body 3 near the lower position, and the side end of the second main body 3 is fixedly connected to one end of the fixed guide rod 15. The movable plate 11 is sleeved on the outside of the fixed guide rod 15, and the movable plate 11 is slidably connected to the fixed guide rod 15. The fixed guide rod 15 is a round rod design, and the other end of the fixed guide rod 15 is fixedly connected to the first limiting block 16.

[0031] During operation, the movable plate 11 will move along the outside of the fixed guide rod 15, and the first limiting block 16 is used to limit the position of the movable plate 11.

[0032] Furthermore, a rotating plate 18 is fitted inside the rear end of the first main body 2, and the first main body 2 is rotatably connected to the rotating plate 18. The other end of the rotating plate 18 is fitted on the outside of the fixed rod 17, and the rotating plate 18 is rotatably connected to the fixed rod 17. The left and right ends of the fixed rod 17 are fixedly connected to the second main body 3. The fixed rod 17 is a circular rod design.

[0033] During operation, the second main body 3 rotates, and the rotating plate 18 rotates along the inside of the first main body 2 and moves into the storage slot 20 opened in the second main body 3. At the same time, the rotating plate 18 rotates along the outside of the fixed rod 17.

[0034] Furthermore, the fixing rod 17 is also provided with second limiting blocks 19 on both the left and right sides, and the fixing rod 17 is fixedly connected to the inner wall of the second limiting block 19. The second limiting block 19 is a circular design.

[0035] During operation, the second limit block 19 can limit the position of the rotating plate 18.

[0036] Working principle: When the second main body 3 rotates, the rotating plate 18 will rotate along the interior of the first main body 2 and move into the storage slot 20 opened in the second main body 3. At the same time, the rotating plate 18 rotates along the outside of the fixed rod 17, and the second limiting block 19 can limit the position of the rotating plate 18 until the rotating plate 18 rotates into the storage slot 20. When the rotating plate 18 reaches the storage slot 20 and contacts the moving positioning rod 10, since both the upper and lower ends of the moving positioning rod 10 are designed with bevels, the rotating plate 18 contacts the moving positioning rod 10 and continues to move into the storage slot 20, thereby squeezing the moving positioning rod 10 outward. When the moving positioning rod 10 moves outward, it will move outward along the interior of the second main body 3. At the same time, the moving positioning rod 10 drives the moving plate 11 to move outward. When moving outward, it will move outward along the inside of the fixed sleeve 12, and the fixed support rod 13 is used to fix and support the position of the fixed sleeve 12. At the same time, when the moving plate 11 moves outward, it will pull the return spring 14 to extend. Simultaneously, the moving plate 11 will move along the outside of the fixed guide rod 15, and the first limit block 16 is used to limit the position of the moving plate 11 until the rotating plate 18 has completely rotated and moved into the storage groove 20 and disengaged from the moving positioning rod 10. The moving positioning rod 10 will automatically reset under the rebound force of the return spring 14 and press against the rotating plate 18 to position it. When it is necessary to close, only a large external force needs to be applied to drive the rotating plate 18 to rotate outward and disengage from the storage groove 20. During the process, the rotating plate 18 will press against the inclined surface below the moving positioning rod 10 and squeeze the moving positioning rod 10 again to move outward until it disengages.
