[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figure 1-6 This utility model provides a hinge structure that can limit the opening angle of the hinge cup 1, including the hinge cup 1, the hinge arm 2 and the rocker arm assembly. The hinge cup 1 and the hinge arm 2 are hinged to open and close through the rocker arm assembly. The hinge cup 1 is used to be installed on the cabinet door, and the hinge arm 2 is installed on the cabinet body through a fixed base, thereby realizing the hinged opening and closing between the cabinet door and the cabinet body.

[0023] The rocker arm assembly includes an outer rocker arm 3 and an inner rocker arm 4. One end of the outer rocker arm 3 is hinged to the hinge cup 1, and the other end is hinged to the hinge arm 2. One end of the inner rocker arm 4 is hinged to the hinge cup 1, and the other end is hinged to the hinge arm 2. It also includes a pin 5 passing through the hinge cup 1 and a detachable limiting clip 6 that is snapped onto the pin 5. One end of the inner rocker arm 4 is fitted onto the pin 5 and hinged to the hinge cup 1 via the pin 5. When the hinge cup 1 is opened, the outer rocker arm 3 and the inner rocker arm 4 can be simultaneously driven to swing. When the hinge cup 1 is opened to a certain angle, the limiting clip 6 abuts against the outer rocker arm 3 and the hinge cup 1 respectively to limit and fix the hinge cup 1.

[0024] Therefore, by embedding the limiting clip 6 on the pin 5 of the hinge cup 1, when the hinge cup 1 is opened to a certain angle, the limiting clip 6 can abut against the outer rocker arm 3 and the hinge cup 1 respectively to limit and fix the hinge cup 1, thereby limiting the opening angle of the cabinet door. The structure is simple and highly practical. In addition, since the limiting clip 6 is detachably embedded on the pin 5, when it is not necessary to limit the opening angle of the hinge cup 1, the limiting clip 6 can be removed, which is very convenient.

[0025] See Figure 3 and Figure 5 The limiting clip 6 includes a main board 61 and two side plates 62 located on both sides of the main board 61. Each side plate 62 has a locking hole 621. The limiting clip 6 is detachably engaged with the pin 5 through the locking hole 621. Specifically, the locking hole 621 includes an inlet portion 6211 and a locking portion 6212, with the inlet portion 6211 and the locking portion 6212 communicating. The inlet portion 6211 has an opening, and inlet ramps 62111 are formed on both sides of the inlet portion 6211.

[0026] Therefore, when it is necessary to insert the limiting clip 6 into the pin 5, it first passes through the opening of the guide part 6211 into the pin 5, then the guide inclined surface 62111 slides into the pin 5 to make the clamping part 6212 gradually approach the pin 5, and finally the clamping part 6212 and the pin 5 are clamped together to achieve the snap-fit ​​assembly.

[0027] See Figure 1 and Figure 4 The main board 61 and the two side plates 62 form a clearance groove. One end of the inner rocker arm 4 is bent to form a bent portion 41 for fitting onto the pin 5. This bent portion 41 is located within the clearance groove. Additionally, the hinge cup 1 has a groove 11 configured to accommodate at least a portion of the outer rocker arm 3 and the inner rocker arm 4 when the hinge cup 1 is closed. The hinge cup 1 also has a clearance hole 12 communicating with the groove 11, which is used to allow clearance from the main board 61.

[0028] Therefore, when the hinge cup 1 is fully opened, the top wall of the main board 61 and the two side plates 62 will abut against the outer rocker arm 3, and the bottom wall of the main board 61 and the two side plates 62 will abut against the hinge cup 1, thereby limiting the hinge cup 1 to prevent it from continuing to open.

[0029] In this embodiment, the motherboard 61 and the two side panels 62 are integrally formed.

[0030] In this embodiment, the limiting clip 6 is made of plastic. Of course, in other embodiments, the limiting clip 6 can also be made of other elastic materials, and this is not a limitation.

[0031] See Figure 2 and Figure 6 The hinge structure also includes a buffer assembly 8 disposed at the hinge cup 1. The buffer assembly 8 includes a buffer 82 and a drive block 81 that is driven and engaged with the buffer 82. The drive block 81 is driven and connected to the rocker arm assembly. When the hinge cup 1 is closed to a certain angle, the rocker arm assembly drives the drive block 81 to drive the buffer 82 to move. The buffer 82 provides a buffering effect on the hinge cup 1 to achieve door closing buffering.

[0032] Specifically, it also includes a drive shaft 7 that passes through the hinge cup 1. One end of the outer rocker arm 3 is fitted onto the drive shaft 7 and hinged to the hinge cup 1 via the drive shaft 7. The drive block 81 is fitted onto the drive shaft 7 and is linked to the drive shaft 7, thereby realizing its transmission connection with the outer rocker arm 3. Thus, when the outer rocker arm 3 is driven to swing, the drive block 81 can be driven to rotate via the drive shaft 7 to drive the buffer 82 to move.

[0033] The buffer 82 includes a cylinder 821 and a piston rod 822. A transmission block 83 is provided between the piston rod 822 and the drive block 81 to achieve a transmission connection. Specifically, the transmission block 83 is used for the piston rod 822 and the drive block 81 to abut against each other to achieve a transmission connection.

[0034] Therefore, when the hinge cup 1 is closed, the outer rocker arm 3 can swing synchronously, which in turn drives the drive block 81 to rotate synchronously. When the hinge cup 1 is closed to a certain angle, the outer rocker arm 3 drives the drive block 81 to abut against the transmission block 83, and the transmission block 83 abuts against and compresses the piston rod 822, thereby generating a buffering effect on the hinge cup 1.

[0035] In this embodiment, the buffer assembly 8 further includes a mounting base 84 mounted on the side of the hinge cup 1 and located outside the groove 11, and the buffer assembly 8 is disposed within the mounting base 84.

[0036] In summary, the hinge structure provided by this utility model, which can limit the opening angle of the hinge cup 1, uses a limiting clip 6 embedded in the pin 5 of the hinge cup 1. When the hinge cup 1 is opened to a certain angle, the limiting clip 6 can abut against the outer rocker arm 3 and the hinge cup 1 respectively to limit and fix the hinge cup 1, thereby limiting the opening angle of the cabinet door. The structure is simple and highly practical. In addition, since the limiting clip 6 is detachably embedded in the pin 5, it can be removed when the hinge cup 1 is closed when it is not necessary to limit the opening angle of the hinge cup 1, which is very convenient to operate.
