Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, specifically a hinge with a limiting structure. Background Technology
[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow relative rotation between them. It is widely used in various industries. A hinge consists of two hinges: a fixed hinge that is fixed to the door frame and a movable hinge that is mounted on the door or window sash. The two hinges are connected by a pin, which serves as the central axis of rotation.
[0003] Existing patent CN22134664U discloses a hinge, including a connecting block and a rotating shaft. Limiting caps are fixed to the upper and lower ends of the rotating shaft. Two fixing flaps are fixed to the left end of the connecting block, spaced apart vertically and located between the two limiting caps. The left parts of the two fixing flaps are rotatably connected to the rotating shaft. A washer is provided at the end of each fixing flap that is close to each other, and both washers are fitted onto the rotating shaft. This invention connects multiple hinges through a connecting block and a connecting groove.
[0004] However, existing hinges still have certain drawbacks. During use, the hinges have a large rotation angle, while the hinges with positioning structures have a fixed positioning angle, making it difficult to precisely adjust the hinge's limit. This causes inconvenience when it is necessary to control the hinge's rotation angle.
[0005] Based on this, a hinge with a limiting structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0006] The purpose of this invention is to provide a hinge with a limiting structure to solve the problem of inconvenient adjustment of the limiting angle in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: A hinge with a limiting structure includes an upper hinge plate, two upper connecting grooves are formed on both sides of the interior of the upper hinge plate, and two upper connecting rings are installed on the two right sides of the upper hinge plate; A damping assembly is installed on one side of the upper connecting ring. The damping assembly includes a support tube, which is installed on one side of the upper connecting ring. A damper is installed on the outside of the support tube, and a fixing tube is installed on the outside of the damper. A fixing groove is opened inside the fixing tube. A connecting component is installed on the outside of the fixed tube; An adjustment component is installed inside the fixing groove.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a rotating rod is rotatably connected inside the upper connecting ring, and a lower connecting ring is rotatably connected to the outer middle part of the rotating rod.
[0009] In one alternative: a lower hinge plate is installed on one side of the lower connecting ring, and two lower connecting grooves are formed on both sides of the interior of the lower hinge plate.
[0010] In one alternative: the connecting assembly includes a mounting ring mounted on the outside of the fixing tube, and a first slot is mounted on one side of the mounting ring.
[0011] In one alternative: the adjusting assembly includes a spring mounted inside a fixing groove, and a support ring is mounted on one side of the spring.
[0012] In one alternative: a limiting component is installed on the outer side of the support ring.
[0013] In one alternative: a fixing ring is installed on the outer side of the support ring, a second slot is installed on one side of the fixing ring, and a limit plate is installed on one side of the fixing ring.
[0014] In one alternative: the limiting plate is L-shaped and is made of high-carbon alloy steel.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using a damping component, this utility model can buffer the impact when the limiting plate is subjected to a large impact force through the rotation of the damper, thus avoiding the problem of damage to the hinge limiting component due to excessive impact force, and improving the practicality of the device. The angle of the limiting plate can be easily adjusted by adjusting the component, so that the hinge can limit the position at different angles.
[0016] 2. This utility model uses the limiting component and the connecting component to be connected by the first slot and the second slot to support the angle of the limiting plate, thereby improving the convenience of the device and facilitating quick adjustment of the limiting angle. By using two limiting plates to limit both sides of the hinge at the same time, the limiting effect and practicality of the device are improved. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] In one embodiment, such as Figures 1-4 As shown, a hinge with a limiting structure includes an upper hinge plate 1, two upper connecting grooves 11 are opened on both sides of the interior of the upper hinge plate 1, and two upper connecting rings 12 are installed on the two right sides of the upper hinge plate 1. A damping assembly is installed on one side of the upper connecting ring 12. The damping assembly includes a support tube 2. The support tube 2 is installed on one side of the upper connecting ring 12. A damper 21 is installed on the outside of the support tube 2. A fixing tube 22 is installed on the outside of the damper 21. A fixing groove 23 is opened inside the fixing tube 22. A connecting component is installed on the outside of the fixed tube 22; An adjustment component is installed inside the fixing groove 23.
[0024] In this embodiment, the upper hinge plate 1 is installed by passing bolts or rivets through the upper connecting groove 11 inside the upper hinge plate 1. The upper hinge plate 1 supports the upper connecting ring 12, and the support tube 2 supports the damper 21. When the device is subjected to a large impact, the rotation of the damper 21 provides a buffering effect, avoiding damage to the equipment. The fixing groove 23 inside the fixing tube 22 supports the adjustment component, and the connection component and the limiting component are connected.
[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, a rotating rod 13 is rotatably connected inside the upper connecting ring 12, and a lower connecting ring 14 is rotatably connected to the outer middle of the rotating rod 13. The lower connecting ring 14 is rotated on its outer side by rotating the rod 13.
[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, a lower hinge plate 15 is installed on one side of the lower connecting ring 14. Two lower connecting grooves 16 are opened on both sides of the interior of the lower hinge plate 15. Bolts or rivets are passed through the lower connecting grooves 16 inside the lower hinge plate 15 to install and fix the lower hinge plate 15.
[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the connecting assembly includes a mounting ring 24, which is mounted on the outside of the fixing tube 22. A first slot 25 is mounted on one side of the mounting ring 24, and the mounting ring 24 supports the first slot 25.
[0028] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment component includes a spring 3, which is installed inside the fixing groove 23. A support ring 31 is installed on one side of the spring 3. The spring 3 facilitates the connection of the support ring 31, and pulling the support ring 31 facilitates the disengagement of the limiting component from the first slot 25.
[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, a limiting component is installed on the outer side of the support ring 31 to limit the hinge.
[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, a fixing ring 32 is installed on the outer side of the support ring 31. A second slot 33 is installed on one side of the fixing ring 32, and a limiting plate 34 is installed on one side of the fixing ring 32. The limiting plate 34 is supported by the interlocking connection of the second slot 33 and the first slot 25, thereby fixing the angle of the limiting plate 34.
[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, the limiting plate 34 is L-shaped and made of high-carbon alloy steel. The high strength of the limiting plate 34 avoids the problem of breakage when limiting the hinge.
[0032] The above embodiment discloses a hinge with a limiting structure. Bolts or rivets pass through the upper connecting groove 11 inside the upper hinge plate 1 and the lower connecting groove 16 inside the lower hinge plate 15, facilitating the installation of the hinge. A rotating rod 13 supports the upper connecting ring 12 and the lower connecting ring 14, allowing for a rotatable connection between the upper hinge plate 1 and the lower hinge plate 15. A support tube 2 supports the damper 21. When the angle of the limiting plate 34 needs adjustment, pulling the limiting plate 34 causes the support ring 31 to slide outward in the fixing groove 23 inside the fixing tube 22, extending the spring 3 and disengaging the first locking groove 25 inside the mounting ring 24 and the second locking groove 33 inside the fixing ring 32. Rotating the support ring 31 allows for... The angle of the limiting plate 34 is adjusted by moving the limiting plate 34. The support ring 31 is released, and the spring 3 automatically rebounds, causing the second slot 33 on one side of the fixing ring 32 to insert into the first slot 25 on the one side of the mounting ring 24. This allows the first slot 25 and the second slot 33 to engage and connect, facilitating the positioning of the angle of the limiting plate 34. When the lower hinge plate 15 is flipped, it is limited by the two limiting plates 34, improving the convenience and limiting effect of the device. When the hinge is closed with excessive force, the lower hinge plate 15 impacts the limiting plate 34. The impact is buffered by the rotation of the damper 21, preventing damage to the hinge limiting structure due to excessive impact force, thus improving the practicality of the device.
[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
