Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge structure. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. It is commonly found in doors, windows, furniture, and other components that require opening and closing. Conventional hinges with adjustable angles have fewer positions, cannot achieve 360° adjustment, and require resetting to the original position after adjustment. Furthermore, the adjustment of the positions is not flexible. Utility Model Content

[0003] The purpose of this invention is to provide a hinge structure with flexible gear adjustment.

[0004] To achieve the above objectives, this utility model proposes a hinge structure, including a first rotating part, a second rotating part, an adjusting part, a clutch member, and an elastic member. The first rotating part is stacked on top of the second rotating part and is hinged to the second rotating part. The clutch member is coaxially arranged with the second rotating part and is slidably connected to the second rotating part in the vertical direction. The clutch member and the second rotating part are engaged with the second rotating part in the circumferential direction. The clutch member and the first rotating part are arranged opposite to each other. One of the clutch member and the first rotating part has a plurality of limit holes arranged in a ring, and the other has a plurality of limit blocks arranged in a ring that can be inserted into the limit holes. The elastic member is used to apply an upward elastic force directly or indirectly to the clutch member to keep the limit holes and limit blocks engaged, thereby locking the rotation of the first rotating part and the second rotating part. The adjusting part is connected to the clutch member and provides a force application point. By applying external force to the adjusting part, the clutch member is driven to move downward, thereby releasing the rotation lock of the first rotating part and the second rotating part.

[0005] Preferably, the adjusting part is a hinge shaft with a T-shaped head that extends upward in the vertical direction, and the first rotating part is provided with a through hole, through which the adjusting part passes and is fixedly connected to the clutch.

[0006] Preferably, the elastic element is sleeved on the hinge shaft and disposed between the T-shaped head of the hinge shaft and the first rotating part.

[0007] Preferably, the second rotating part is provided with a receiving cavity with an opening facing the first rotating part, and the clutch is disposed in the receiving cavity. One of the receiving cavity and the clutch is provided with a positioning hole, and the other is provided with a positioning block corresponding to the position of the positioning hole. The positioning block extends in the vertical direction, and the positioning hole and the positioning block are slidably connected in the vertical direction and are upper-positioned in the circumferential direction.

[0008] Preferably, the first rotating part is provided with a first swing arm, and the second rotating part is provided with a second swing arm.

[0009] The beneficial effects of this utility model are as follows:

[0010] The hinge proposed in this utility model includes a first rotating part, a second rotating part, an adjusting part, a clutch element, and an elastic element. The first rotating part is superimposed on the second rotating part and is hinged to the second rotating part, more specifically, it is a hinge that can be locked relative to the rotation. The locking and unlocking functions of the first and second rotating parts are realized by a clutch element provided between the first and second rotating parts. The clutch element is coaxially arranged with the second rotating part, and the clutch element is slidably connected to the second rotating part in the vertical direction and is engaged with the second rotating part in the circumferential direction. The clutch element and the first rotating part are arranged opposite to each other. One of the clutch element and the first rotating part has a plurality of limit holes arranged in a ring, and the other has a plurality of limit blocks arranged in a ring that can be inserted into the limit holes. The elastic element is used to apply an upward elastic force directly or indirectly to the clutch element to keep the limit holes and limit blocks engaged, thereby locking the rotation of the first and second rotating parts. This allows the first and second rotating parts to rotate and be fixed at any angle an unlimited number of times without needing to re-adjust them between adjustments. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] See Figure 1-4 As shown, in a preferred embodiment of this utility model, a hinge structure is proposed, including a first rotating part 2, a second rotating part 3, an adjusting part 1, a clutch 4, and an elastic element 5. The first rotating part 2 is superimposed on the second rotating part 3 and the first rotating part 2 and the second rotating part 3 are hinged together. More specifically, the first rotating part 2 and the second rotating part 3 are relatively rotatably lockable hinges, wherein the locking and unlocking functions are structurally realized by the adjusting part 1, the clutch 4, and the elastic element 5.

[0019] The clutch 4 is disposed between the first rotating part 2 and the second rotating part 3. The second rotating part 3 has a receiving cavity 31 with an opening facing the first rotating part 2. The clutch 4 is placed in the receiving cavity 31. The clutch 4 has a positioning hole 41. The receiving cavity 31 has a positioning block 32 protruding towards the cavity. The positioning block 32 extends in the vertical direction. The positioning hole 41 and the positioning block 32 are slidably connected and engaged. There are multiple sets of positioning holes 41 and positioning blocks 32. In this way, due to the limiting engagement formed by the positioning hole 41 and the positioning block 32, the clutch 4 and the second rotating part 3 are engaged in a circumferential upper limit engagement in the second rotating part 3. The clutch 4 and the second rotating part 3 are coaxially arranged, and the clutch 4 and the second rotating part 3 are slidably connected in the vertical direction.

[0020] In other embodiments, the receiving cavity 31 may be omitted, and the clutch 4 and the second rotating part 3 may be connected solely through the positioning hole 41 and the positioning block 32. Furthermore, the positioning hole 41 and the positioning block 32 may be reversed, i.e., a protruding positioning block structure is provided on the clutch 4, and a recessed positioning hole structure is provided within the receiving cavity 31. In this embodiment, the positioning hole 41 and the positioning block 32 are provided in two sets at 180° intervals. In other embodiments, three, four, or more sets of positioning holes 41 and positioning blocks 32 may be provided.

[0021] The clutch 4 has a plurality of annularly arranged limiting holes 42, and the first rotating part 2 has a plurality of annularly arranged limiting blocks 21 that can be inserted into the limiting holes 42. Thus, when the limiting blocks 21 on the first rotating part 2 are inserted into the limiting holes 42 on the clutch 4, the relative rotation between the first rotating part 2 and the second rotating part 3 is locked. Once the limiting blocks 21 on the first rotating part 2 disengage from the limiting holes 42 on the clutch 4, the relative rotation between the first rotating part 2 and the second rotating part 3 is unlocked. Both the limiting holes 42 and the limiting blocks 21 are provided in N numbers along the circumference of the first rotating part 2, where N is greater than or equal to 2. Therefore, the first rotating part 2 can be locked by the clutch 4 for every (360 / N)° of rotation, which facilitates adjustment of the locking angle of the first rotating part 2 relative to the second rotating part 3.

[0022] The limiting hole 42 and the limiting block 21 can also be reversed, that is, multiple annularly arranged limiting holes are provided on the first rotating part, and multiple annularly arranged upward protruding limiting blocks are provided on the clutch for insertion into the limiting holes, so as to realize the insertion between the clutch and the first rotating part.

[0023] The up-and-down sliding of the clutch 4 corresponds to the insertion or disengagement of the limiting block 21 and the limiting hole 42. When the clutch 4 slides upward and remains in the upper position, the limiting block 21 and the limiting hole 42 remain engaged. When the clutch 4 slides downward, the connection between the limiting block 21 and the limiting hole 42 disengages. The up-and-down sliding of the clutch 4 is controlled by the adjusting part 1 and the elastic element 5. The adjusting part 1 is a hinge shaft with a T-shaped head that extends upward in the vertical direction. The first rotating part 2 is provided with a through hole 23, through which the hinge shaft passes and is fixedly connected to the clutch 4 (this fixed connection is an interference fit connection in this embodiment). Thus, the adjusting part 1 also serves as the shaft for hinged connection between the first rotating part 2 and the second rotating part 3. Of course, in other embodiments, other structures can also be used to achieve the hinge connection between the first rotating part 2 and the second rotating part 3.

[0024] An elastic element 5 is disposed between the T-shaped head of the first rotating part 2 and the adjusting part 1. In this embodiment, the elastic element 5 is a compression spring. Since the adjusting part 1 and the clutch 4 are fixedly connected, the upward elastic force applied by the elastic element 5 can indirectly act on the clutch 4. Therefore, in the natural state, due to the elastic force of the elastic element 5, the clutch 4 is held in the upper position, and the limiting hole 42 and the limiting block 21 remain engaged, thereby locking the rotation of the first rotating part 2 and the second rotating part 3. When it is necessary to unlock the first rotating part 2 and the second rotating part 3, a downward force is applied to the head of the adjusting part 1 to separate the clutch 4 from the first rotating part 2. At this time, the limiting hole 42 and the limiting block 21 separate, and the first rotating part 2 and the second rotating part 3 are unlocked to achieve relative rotation between them. This allows the first rotating part 2 and the second rotating part 3 to rotate and be fixed at any angle an unlimited number of times without having to re-adjust the first rotating part 2 and the second rotating part 3 between the next adjustment.

[0025] In other embodiments, such as Figure 5As shown, the elastic element 5' can also be disposed between the clutch 4 and the second rotating part 3 to directly apply an upward elastic force to the clutch 4, so that the limiting hole 42 and the limiting block 21 remain engaged, realizing a lockable hinge between the first rotating part 2 and the second rotating part 3. In this embodiment, the adjusting part 1' can be integrally formed with the clutch 4. In this embodiment, the adjusting part 4 can simply be a shaft extending upward in the vertical direction for hinged connection between the first rotating part 2 and the second rotating part 3. Of course, the adjusting part can also be designed to be detachably connected to the clutch, that is, a stepped hole with a stepped surface facing the first rotating part can be provided on the clutch, and one end of the adjusting part can be adapted to the shape of the stepped hole. The adjusting part 1' only needs to provide a force application point to realize the tight contact and separation of the first rotating part 2 and the clutch 4, satisfying the locking and unlocking of the first rotating part 2 and the second rotating part 3 during relative rotation.

[0026] The locking and unlocking of the first rotating part 2 and the second rotating part 3 is achieved by setting a clutch 4 between them. When the clutch 4 ages or is damaged, the hinge structure can be repaired by replacing the clutch 4 without replacing the entire second rotating part 3, which is more convenient and reduces repair costs. In other embodiments, a circular receiving cavity 31 can be used instead of a circular one to achieve the same effect of restricting the rotation of the clutch 4 within the receiving cavity 31.

[0027] In order to facilitate the angle adjustment between the first rotating part 2 and the second rotating part 3, in this embodiment, the first rotating part 2 is provided with a first swing arm 22 and the second rotating part 3 is provided with a second swing arm 33.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
