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, also known as a hinge leaf, is a component that connects two parts of an object and allows them to move. It is commonly used in cabinet doors, windows, and doors.

[0003] Conventional hinges on the market lack a positioning function. In this case, the door or window sash is prone to rotating around the pivot point under slight external forces (such as wind or accidental contact) and colliding with other objects, causing unnecessary damage. If a positioning function is needed, the conventional approach is to add accessories, such as door catches or positioners; however, adding door catches and positioners increases costs and installation difficulty, and may also affect the overall appearance of the hinged door. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a hinge structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hinge structure includes a first hinge plate, a second hinge plate, and a rivet rotatably connecting the two. A first sleeve is provided on one side of the first hinge plate, and a second sleeve is provided on one side of the second hinge plate. The rivet passes through the first sleeve and the second sleeve respectively. A V-shaped elastic piece is provided at the end of the first sleeve near the second sleeve. A plurality of positioning grooves are evenly distributed along the circumference at the end of the second sleeve near the first sleeve, and one end of the V-shaped elastic piece abuts against the positioning groove.

[0007] In some embodiments, a T-shaped groove is provided on the outer wall of the first sleeve along its axial direction. A support block is provided in the T-shaped groove, and a V-shaped elastic sheet is provided in the T-shaped groove. The end cap of the rivet can restrict the support block from moving outward along the T-shaped groove. The other end of the support block abuts against the V-shaped elastic sheet, so that one end of the V-shaped elastic sheet remains extended outward and abuts against the positioning groove.

[0008] In some embodiments, a limiting flange is provided at the inner end of the T-shaped groove, and outwardly extending baffles are provided at both ends of the V-shaped elastic sheet opening. The baffles abut against the limiting flange and are pressed together by the support block.

[0009] In some embodiments, two first sleeves are provided at intervals, and a second sleeve is provided between the two first sleeves.

[0010] In some embodiments, the end of the rivet away from the end cap is provided with a threaded hole, and a nut is threaded into the threaded hole.

[0011] In some embodiments, four or eight positioning slots are evenly distributed along the circumference.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a V-shaped elastic piece at one end of the first sleeve near the second sleeve, and having a plurality of positioning grooves evenly distributed along the circumference at one end of the second sleeve near the first sleeve, with one end of the V-shaped elastic piece abutting against the positioning groove, that is, positioning can be achieved by the elasticity of the V-shaped elastic piece itself and the positioning groove, thereby realizing the positioning and fixing between the sash hinge and the frame hinge while the door or window sash is opening and closing, improving the stability during use, and having a simple structure and low cost.

[0017] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0018] like Figures 1-4 The hinge structure shown includes a first hinge plate 1, a second hinge plate 2, and a rivet 3 rotatably connecting the two. A first sleeve 4 is provided on one side of the first hinge plate 1, and a second sleeve 5 is provided on one side of the second hinge plate 2. The rivet 3 passes through the first sleeve 4 and the second sleeve 5 respectively. A V-shaped elastic piece 6 is provided at the end of the first sleeve 4 near the second sleeve 5. A plurality of positioning grooves 7 are evenly distributed around the circumference at the end of the second sleeve 5 near the first sleeve 4. One end of the V-shaped elastic piece 6 abuts against the positioning groove 7.

[0019] Based on the above structure, the V-shaped elastic sheet 6 can be positioned by its own elasticity and positioning groove 7, thereby enabling the door or window sash to be opened and closed while the sash hinge and frame hinge are positioned and fixed, improving the stability during use. The structure is simple and the cost is low.

[0020] See Figures 2-4 As shown, a T-shaped groove 21 is provided on the outer wall of the first sleeve 4 along its axial direction. A support block 22 is provided in the T-shaped groove 21. The V-shaped elastic sheet 6 is provided in the T-shaped groove 21. The end cap 30 of the rivet 3 can restrict the support block 22 from moving outward along the T-shaped groove 21. The other end of the support block 22 abuts against the V-shaped elastic sheet 6, so that one end of the V-shaped elastic sheet 6 is kept extending outward and abutting against the positioning groove 7.

[0021] Furthermore, a limiting flange 31 is provided at the inner end of the T-shaped groove 21, and outwardly extending baffles 32 are provided at both ends of the opening of the V-shaped elastic sheet 6. The baffles 32 abut against the limiting flange 31 and are pressed tightly by the support block 22.

[0022] When installing the V-shaped elastic sheet 6, it can be placed into the T-shaped slide groove 21. The baffle 32 of the T-shaped slide groove 21 is set on the limiting flange 31 to position the V-shaped elastic sheet 6, while the other end of the V-shaped elastic sheet 6 extends out of the T-shaped slide groove 21. Then, the support block 22 is placed in and the baffle 32 is pressed. Finally, the rivet 3 is inserted. However, the end cap 30 of the rivet 3 can restrict the support block 22 from moving outward along the T-shaped slide groove 21, thereby fixing the V-shaped elastic sheet 6. The structure is simple and the installation is convenient.

[0023] In addition, the T-shaped groove 21 is provided on the outer wall of the first sleeve 4, which facilitates its processing and forming.

[0024] Preferably, there are two first sleeves 4 spaced apart, and the second sleeve 5 is disposed between the two first sleeves 4. Of course, each first sleeve 4 is provided with a T-shaped groove 21, a V-shaped elastic sheet 6 and a support block 22 to improve the stability during positioning.

[0025] The rivet 3 has a threaded hole 51 at the end away from the end cap 30. A nut 52 is internally threaded into the threaded hole 51. After the nut 52 is connected to the threaded hole 51, it can restrict the support block 22 from moving outward along the T-shaped slide groove 21.

[0026] Preferably, four or eight positioning grooves 7 are evenly distributed along the circumference.
