Description

Technical Field

[0001] The present application relates to the technical field of hinges, and in particular to a hinge. Background Art

[0002] In the prior art, hinges are a mechanical connection device widely used to achieve relative rotation between two solid objects. These devices typically consist of two main components: two connecting pieces and a rotating shaft. In this structure, each end of the connecting piece is fitted with a sleeve that mates with the rotating connection point of the shaft. By fitting the sleeves of the two connecting pieces onto the shaft, a rotational connection is achieved.

[0003] However, in traditional designs, once the two connecting pieces are attached to the shaft via their sleeves, riveted stoppers are placed at each end of the shaft to prevent the two connecting pieces from falling off the shaft. While this riveted structure provides a certain degree of connection stability, it also presents a significant drawback: once riveted, the hinge becomes a single, integral unit, making replacement or repair particularly inconvenient. Utility Model Content

[0004] In order to improve the inconvenience of replacing or repairing a hinge, the present application provides a hinge.

[0005] This application provides a hinge, which adopts the following technical solution:

[0006] A hinge includes two connecting plates and a rotating shaft. One side of each connecting plate is fixed with a shaft sleeve mounted on the rotating shaft. One end of the rotating shaft is fixed with a limit block. The rotating shaft is provided with a limit spring for preventing the fixed plate and the connecting plate from detaching from the rotating shaft. The rotating shaft is provided with a slot for the limit spring to be engaged.

[0007] By adopting the above technical solution and designing the limit block and the limit spring, it is ensured that the connecting piece will not fall off the rotating shaft, and the hinge is detachable, which is convenient for maintenance and replacement.

[0008] Optionally, the limit block and the rotating shaft are an integrally formed structure.

[0009] By adopting the above technical solution, the strength and stability of the overall structure are enhanced, while the manufacturing process is simplified and the production cost is reduced.

[0010] Optionally, one end of the rotating shaft away from the limiting block is provided with a chamfer.

[0011] By adopting the above technical solution, the chamfered design facilitates the installation and disassembly of the shaft, reducing friction and resistance during operation.

[0012] Optionally, two sleeves of one of the connecting pieces are fixed along one side of the fixing piece, the sleeve of the other connecting piece is located between the two sleeves of the fixing piece, and the limiting retaining spring is located between adjacent sleeves.

[0013] By adopting the above technical solution, the limiting retaining spring is arranged between the two shaft sleeves, which can effectively prevent the connecting piece from being separated from the rotating shaft on the one hand, and can shorten the length of the rotating shaft and reduce costs on the other hand.

[0014] Optionally, a drag reducing member is mounted on the rotating shaft, and the drag reducing member is located between adjacent sleeves to reduce the friction resistance between the two connecting plates.

[0015] By adopting the above technical solution, the friction resistance of the connecting piece during rotation is reduced, the rotation is made smoother, and the service life of the hinge is extended.

[0016] Optionally, the drag reducing member is a thrust bearing sleeved on the rotating shaft.

[0017] By adopting the above technical solution, not only the friction resistance is reduced and the noise is reduced, but also more stable rotation support is provided, thereby improving the overall performance of the hinge.

[0018] Optionally, the sleeve of the connecting piece is arranged to be tilted upward, and the outer contour of the sleeve is higher than the side of the connecting piece away from the tilting direction of the sleeve.

[0019] By adopting the above technical solution, when the connecting piece is fixed, the shaft sleeve does not contact the carrier of the connecting piece.

[0020] In summary, this application has at least one of the following beneficial effects:

[0021] 1. By employing a stopper and retaining spring, the present invention achieves detachable hinges. This design allows users to easily remove and reinstall the hinge when replacement or repair is necessary without destroying or damaging any components. This significantly improves the maintainability and ease of use of the hinge, reducing maintenance costs and time.

[0022] 2. A thrust bearing is installed on the rotating shaft as a drag reducing part. This design not only reduces the friction resistance of the connecting piece during rotation, but also reduces noise; it also improves the rotation flexibility and service life of the hinge.

[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] The embodiments of the present application disclose a hinge, which aims to solve the problems of traditional hinges being non-detachable and inconvenient to repair.

[0028] Reference Figure 1 、 2 The hinge comprises two connecting pieces 1 and a rotating shaft 2. A sleeve 11 is integrally formed on one side of each connecting piece 1. Sleeve 11 is sleeved onto the rotating shaft 2, achieving a rotational connection between the two connecting pieces 1 and the rotating shaft 2. In actual use, the two connecting pieces 1 can be represented as a fixed piece for fixing to a carrier and a movable piece for fixing to a movable body, respectively.

[0029] The sleeve 11 of the connecting piece 1 is tilted upward, and its outer profile is higher than the side of the connecting piece 1 facing away from the sleeve 11. When the connecting piece 1 is installed, the sleeve 11 does not come into contact with the mounting surface (such as a door frame or cabinet). Furthermore, a certain clearance is maintained between the sleeve 11 and the mounting surface during use. This reduces wear and noise caused by direct contact, improving the hinge's quietness and durability.

[0030] One end of the shaft 2 is fixedly connected to a limit block 21. The limit block 21 and the shaft 2 are integrally formed and can be directly machined, eliminating the need for connecting the limit block 21 to the shaft 2. A chamfer 22 is provided on the end of the shaft 2 away from the limit block 21 to facilitate passage of the shaft 2 through the sleeve 11.

[0031] Reference Figure 2 A retaining spring 23 is also provided on the rotating shaft 2 to prevent the connecting piece 1 from detaching from the rotating shaft 2. Specifically, a slot 24 is provided on the rotating shaft 2 for the retaining spring 23 to engage. The retaining spring 23 is a ring structure larger than one-half of a circle and can be made of plastic with a certain degree of elastic deformation. In the absence of external force, the retaining spring 23 is secured in the slot 24, thereby retaining the connecting piece 1 in position. This prevents the connecting piece 1 from detaching from the rotating shaft 2, even without riveting.

[0032] At the same time, when disassembly is required, the limiting clamping spring 23 can be taken out from the rotating shaft 2 by simply opening the limiting clamping spring 23 from the position of the notch with the help of a tool, thereby realizing the detachability of the hinge.

[0033] Reference Figure 1 、2 In the layout of the connecting pieces 1, one connecting piece 1 has two sleeves 11 fixed along one side of the fixing piece, while the sleeve 11 of the other connecting piece 1 is located between these two sleeves 11, and the limiting spring 23 is located between adjacent sleeves 11. This layout makes the connection more compact and improves the limiting effect. Moreover, because the limiting spring 23 is located between adjacent sleeves 11, compared to the end position, the rotating shaft 2 does not need to be longer than the sleeve 11.

[0034] Reference Figure 1 To reduce frictional resistance during rotation of the connecting piece 1, a drag reducing member 25 is mounted on the rotating shaft 2, located between adjacent sleeves 11. Specifically, the drag reducing member 25 can be a thrust bearing mounted on the rotating shaft 2. Its excellent load-bearing capacity and wear resistance significantly improve the hinge's rotational performance and stability, while also effectively reducing noise during rotation. In other embodiments, the drag reducing member 25 can also be replaced by a spacer, a lubricating coating, or other alternatives.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
