[0013] By adopting the above technical solution, a countersunk groove is opened on the connection side of the connecting seat, which not only provides installation space for the retaining spring, but also makes the installation of the retaining spring more concealed, improves the aesthetics of the hinge, and reduces the potential risk of damage caused by the protrusion of the retaining spring.

[0014] Optionally, a washer is mounted on the rotating shaft, and a groove for installing the washer is formed on a side of the connecting seat away from the countersunk groove.

[0015] By adopting the above technical solution, the friction between the retaining spring and the connecting seat is reduced, the wear is reduced, and the service life of the hinge is increased.

[0016] Optionally, one end of the connecting seat where the through hole is opened is tilted outwards toward one side along the horizontal direction.

[0017] By adopting the above technical solution, the mechanical properties of the hinge during operation are improved and the rotational flexibility of the movable carrier is enhanced.

[0018] In a second aspect, the present application provides a connection structure, which adopts the following technical solution:

[0019] A connection structure includes the above-mentioned hinge and a shaft sleeve, wherein the shaft sleeve is used to be sleeved on the rotating shaft, and the shaft sleeve is provided with a connecting piece for fixed connection with a carrier.

[0020] By adopting the above technical solution, the connection between the hinge and the carrier is made stronger, thereby improving the stability of the overall structure.

[0021] Optionally, the connecting member includes a locking nut, an axially extending external thread is provided on the outer peripheral side of the sleeve, and a limiting ring is coaxially fixed to one end of the sleeve.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] The present application discloses a hinge, referring to Figure 1 、 2 The hinge comprises a connecting base 1 and a rotating shaft 2. The connecting base 1 is fixed to the upper and lower end surfaces of a movable support, such as a door, while the rotating shaft 2 is vertically connected to one end of the connecting base 1 for rotational connection with another fixed support, such as a door frame. In other words, the hinge is located on the upper and lower sides of the two supports, which are obscured by the supports themselves, improving the overall aesthetics while reducing the space occupied by the adjacent sides.

[0037] Reference Figure 1 、 2 The connection base 1 is provided with a connection hole 11, and the connection base 1 can be fixed on the carrier by the cooperation of bolts and nuts. When facing a carrier with a frame, the connection base 1 can be hidden in the frame of the carrier.

[0038] Reference Figure 2 、3 One end of the connector 1 defines a through hole 12, through which the shaft 2 is rotatably connected to the connector 1. One end of the shaft 2 is chamfered to facilitate insertion into the carrier for a secure connection. To ensure that the shaft 2 does not separate from the connector 1, a limiter is provided on the shaft 2.

[0039] Specifically, refer to Figure 4 The limiting member includes a retaining spring 21, which can be made of deformable plastic or metal. The rotating shaft 2 is provided with two annular grooves 22 for the retaining spring 21 to engage, and the connecting base 1 is located between the two annular grooves 22. In this way, the retaining spring 21 can effectively prevent the rotating shaft 2 from falling out of the connecting base 1.

[0040] Reference Figure 2 The connection side of the connecting base 1 is provided with a countersunk groove 13, which is coaxial with the through hole 12 and is used to install the circlip 21. One of the circlips 21 can be concealedly installed in the countersunk groove 13 without protruding from the surface of the connecting base 1, avoiding contact with another fixed carrier and reducing wear of the circlip 21.

[0041] Reference Figure 3 、 4 In order to reduce the friction between the other retaining spring 21 and the connecting seat 1, a washer 23 is mounted on the rotating shaft 2, and a groove 14 is provided on the connecting seat 1 for the installation of the washer 23. When the retaining spring 21 rotates with the rotating shaft 2, the washer 23 rotates accordingly, effectively reducing the friction between the retaining spring 21 and the connecting seat 1.

[0042] The present application also discloses a connection structure, referring to Figure 5 、 6 The connection structure includes a sleeve 3, which is used to be sleeved on the rotating shaft 2. A connecting piece is provided on the sleeve 3, and the sleeve 3 is fixedly connected to the carrier through the connecting piece.

[0043] Specifically, refer to Figure 6 、 7 The connecting member includes a lock nut 4. The outer circumference of the sleeve 3 is provided with an axially extending external thread 32. To limit the position of the sleeve 3 on the rotating shaft 2, a limit ring 31 is coaxially fixed to one end of the sleeve 3. During installation, the sleeve 3 is inserted through a mounting hole in the carrier and securely fixed to the carrier by tightening the lock nut 4.

[0044] Reference Figure 6 、 7 To facilitate installation, a positioning notch 33 extending along the axial direction is provided on the external thread 32. The mounting hole has the same structure as the projection surface of the external thread 32 in the axial direction. During installation, the positioning notch 33 can limit the rotation of the sleeve 3, making it easier to tighten the lock nut 4.

[0045] Before installation, first fix the shaft sleeve 3 on the carrier, and then insert the rotating shaft 2 on the connecting seat 1 into the shaft sleeve 3 to form a rotating connection between the two carriers.

[0046] 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.
