[0034] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0035] The present invention provides a waist buckle comprising a first component 1 and a second component 2. The first component 1 and the second component 2 are connected by a mortise and tenon structure, allowing relative rotation between the first component 1 and the second component 2. This means that the first component 1 and the second component 2 form a curved surface that conforms to the human body, improving the fit of the waist buckle. The technical solution of the present invention is described in detail below using a specific structure.

[0036] like Figure 2-8 As shown, the first component 1 includes a first body 11 and a tenon 12 , and the tenon 12 is provided on the first body 11 .

[0037] by Figure 2-6As shown in the perspective, the tenon 12 is arranged on a side of the first body 11 facing the second component 2. The tenon 12 is in the shape of a long cylinder. The tenon 12 is fixedly connected to the side of the first body 11 along its own length direction. After the first component 1 and the second component 2 are connected, the cylindrical tenon 12 can make the first component 1 and the second component 2 rotate relative to each other.

[0038] like Figure 2-6 As shown, the second component 2 includes a second main body 21, and the second main body 21 is provided with a tenon 28 that cooperates with the tenon 12. The tenon 12 is inserted from one end of the tenon 28, and the other end of the tenon 28 is closed to prevent the tenon 12 from escaping from the other end of the tenon 28.

[0039] It is easy to understand that the shape of the tenon 28 is adapted to the tenon 12, that is, the internal space of the tenon 28 is also cylindrical. The tenon 28 is a structure similar to a through groove, one end of which is closed. After the tenon 28 is connected to the tenon 12, the first body 11 and the second body 21 can rotate relative to each other within a certain range.

[0040] The first component 1 and the second component 2 can be stably connected in various ways. For example, the tenon 12 and the tenon groove 28 can be an interference fit to ensure a stable connection between the first component 1 and the second component 2. It is easy to understand that the interference fit of the tenon 12 and the tenon groove 28 can also be adjusted to form a curved surface between the first component 1 and the second component 2 to conform to the human body; or the waist buckle also includes a locking structure 3 to lock the tenon 12 and the tenon groove 28. It should be noted that in the present invention, the locking structure 3 can be various and can be provided within the tenon groove 28 and / or on the tenon 12, as long as it can achieve a stable connection between the first component 1 and the second component 2 and does not affect the relative rotation of the first component 1 and the second component 2. Several feasible locking structures 3 are listed below.

[0041] For example, the locking structure 3 may be a magnet, which is not shown in the accompanying drawings. A magnet may be provided in the tenon 12, and a matching magnet or an iron connector that can be magnetically attracted may be provided in the tenon groove 28. Alternatively, a magnet may be provided in the tenon groove 28, and a matching magnet or an iron connector that can be magnetically attracted may be provided in the tenon 12. After the tenon 12 is inserted into the tenon groove 28, it is fixed by magnetic attraction. Furthermore, a magnet may be provided on the inner wall of the closed end of the tenon groove 28, and a magnet or an iron connector may be provided on the end of the tenon 12 that contacts the inner wall of the closed end of the tenon groove 28.

[0042] For example, the locking structure 3 may also be a cover member, not shown in the drawings. A cover member is provided at the unsealed end of the mortise 28, and the cover member is slidably connected to the side surface of the second body 21. After the tenon 12 is fully inserted into the mortise 28, the cover member slides out of the unsealed end of the mortise 28 and locks it in place, preventing the tenon 12 from slipping out.

[0043] The present invention also proposes another feasible locking structure 3, such as Figure 2-6 As shown, it includes a spring 32 and a bead piece 31, the second main body 21 is provided with a mounting groove 22, and the mounting groove 22 is provided with a connecting hole 29 leading to the tenon 28, the bead piece 31 includes a bead head 311 and a limiting portion 312, the bead head 311 is provided on the limiting portion 312, the size of the bead head 311 is less than or equal to the size of the connecting hole 29, the size of the limiting portion 312 is larger than the size of the limiting portion 312, the bead piece 31 is provided in the mounting groove 22, the bead head 311 extends into the tenon 28 through the connecting hole 29, the spring 32 is provided in the mounting groove 22 and is between the limiting portion 312 and the wall of the mounting groove 22, an annular guide groove 13 is provided on the circumferential side of the tenon 12, the tenon 12 is inserted into the tenon 28, and the bead head 311 of the bead piece 31 is embedded in the annular guide groove 13.

[0044] Preferably, the part where the bead head 311 contacts the tenon 12 is a spherical surface, the connecting hole 29 is a circular hole, the maximum diameter of the bead head 311 is less than or equal to the aperture of the connecting hole 29, the limiting portion 312 is disc-shaped, and the outer diameter of the limiting portion 312 is greater than the aperture of the connecting hole 29.

[0045] The operating principle of the locking structure 3 is as follows: during the insertion of the tenon 12 into the mortise 28, when the portion of the tenon 12 other than the annular guide groove 13 contacts the bead head 311 of the bead member 31, pressure is applied to the bead head 311, causing the bead member 31 to retract entirely into the mounting groove 22. When the tenon 12 moves until the annular guide groove 13 is aligned with the bead member 31, the spring 32 pushes the bead member 31 out, causing the bead head 311 to engage with the annular guide groove 13, locking the tenon 12 in the mortise 28. Similarly, during the separation of the tenon 12 from the mortise 28, when the portion of the tenon 12 other than the annular guide groove 13 contacts the bead head 311 of the bead member 31, pressure is applied to the bead head 311, causing the bead member 31 to retract entirely into the mounting groove 22, allowing the tenon 12 to be smoothly withdrawn.

[0046] It should be noted that the tenon 12 and the mortise 28 are locked by the bead 31, but not tightly locked. Due to the compressibility of the spring 32, the tenon 12 can be inserted into or removed from the mortise 28 by applying sufficient external force to the tenon 12. When the tenon 12, i.e., the first component 1, is not affected by external force, the connection between the first component 1 and the second component 2 will not automatically separate. The annular guide groove 13 and the locking structure 3 not only lock the first component 1 and the second component 2, but also do not hinder the relative rotation of the first component 1 and the second component 2. Since the annular guide groove 13 is arranged along the circumferential side of the tenon 12, the direction of the annular guide groove 13 is consistent with the rotation direction of the tenon 12. When the first component 1 and the second component 2 rotate relative to each other, the friction between the spherical bead head 311 and the annular guide groove 13 is small and does not hinder the rotation of the tenon 12.

[0047] Preferably, in order to reduce the resistance when the tenon 12 is connected to the tenon groove 28, a guide slope 14 is provided at the end of the tenon 12 entering the tenon groove 28, such as Figure 2-3 As shown, when the tenon 12 enters the mortise 28, the end of the tenon 12 provided with the guide bevel 14 enters the mortise 28 first and contacts the bead 31. As the tenon 12 enters the mortise 28, the bead 31 gradually retracts into the mounting groove 22 under the action of the guide bevel 14, thereby reducing the resistance to the connection between the tenon 12 and the mortise 28. It is easy to understand that when the tenon 12 separates from the mortise 28, the separation process of the bead 31 from the annular guide groove 13 is similar to the separation process of the bead 31 from the guide bevel 14, thereby reducing the resistance.

[0048] Preferably, the number of locking structures 3 is greater than or equal to two, and the number of annular guide grooves 13 is less than or equal to the number of locking structures 3. For example, there are two locking structures 3 and one annular guide groove 13. The annular guide groove 13 can cooperate with any of the locking structures 3, reflecting different gear positions when the tenon 12 is connected to the tenon groove 28. More preferably, the number of annular guide grooves 13 is equal to the number of locking structures 3, and the number of annular guide grooves 13 is also greater than or equal to two, and multiple annular guide grooves 13 correspond one-to-one to multiple locking structures 3.

[0049] Preferably, the number of the mounting slots 22 is the same as the number of the locking structures 3 , that is, one locking structure 3 is provided in each mounting slot 22 .

[0050] As shown in the figure, the second body 21 is further provided with a decorative groove 23 and a gasket 24 . The mounting groove 22 is provided in the decorative groove 23 . The gasket 24 is fixed in the decorative groove 23 by screws 26 , and the gasket 24 covers the mounting groove 22 .

[0051] The connection method between the gasket 24 and the decorative groove 23 can be: screw fixing holes 25 are respectively provided at both ends of the gasket 24, and two threaded holes 27 are correspondingly provided on the bottom surface of the decorative groove 23. The gasket 24 is installed in the decorative groove 23, and the two screw fixing holes 25 are respectively aligned with the two threaded holes 27, and two screws 26 are respectively passed through the screw fixing holes 25 and screwed into the two threaded holes 27, so as to fix the gasket 24 in the decorative groove 23.

[0052] In order to pursue the overall beauty of the waist buckle, the first main body 11 is provided with a strip area 15, and the shape of the strip area 15 is the same as that of the gasket 24. A circular area 16 is provided in the strip area 15, and the shape of the circular area 16 is the same as that of the head of the screw 26. That is, on the first main body 11, the strip area 15 imitates the structure of the gasket 24, and the circular area 16 imitates the structure of the screw 26, thereby achieving a symmetrical effect with the second main body 21.

[0053] like Figure 2As shown, both the first body 11 and the second body 21 are provided with a webbing connector 4 to facilitate connection of the first body 11 and the second body 21 with external webbing.

[0054] The embodiments provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
