[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1:

[0025] like Figures 1 to 3 As shown, this utility model embodiment provides a 3D printed integrated buckle, including a locking hook 1, a connecting piece 2 on one side of the locking hook 1, a locking ring 3 that is engaged with the locking hook 1, a connecting piece 4 at the lower end of the locking ring 3, a button 5 that is movably connected to one side of the locking ring 3, a connecting piece 6 at the lower end of the button 5, and the connecting piece 6 and the connecting piece 2 4 that are connected by a connecting block 7.

[0026] This utility model embodiment designs and models the locking hook 1, connecting piece 1 2, locking ring 3, connecting piece 2 4, button 5, connecting piece 3 6, and connecting block 7 as a whole. It is integrally formed using elastic plastic through 3D printing technology. The locking hook 1 is fixedly connected to the connecting piece 1 2, the locking hook 1 is snapped to the locking ring 3, the locking ring 3 is movably connected to the button 5, and the connecting piece 3 6 is fixedly connected to the connecting piece 2 4 through the connecting block 7. The 3D printing integral forming method reduces the assembly process of the parts, improves production efficiency, and reduces production costs. The overall structure design is compact, and the connection between the parts is stable, ensuring the reliability of the buckle.

[0027] In one feasible implementation scheme, such as Figures 1 to 3 As shown, the locking hook 1 is semi-circular, and the side of the locking hook 1 facing the locking ring 3 is inclined, with the inclined surface of the locking hook 1 sloping from a straight edge to an arc edge. By determining the shape of the locking hook 1 as semi-circular, and machining an inclined surface on the side of the locking hook 1 facing the locking ring 3, this inclined surface slopes from a straight edge to an arc edge. During 3D printing, it is directly formed according to this design parameter. The semi-circular locking hook 1 facilitates the snap-fit ​​operation with the locking ring 3, and the inclined surface design makes the locking hook 1 smoother when inserted into the locking ring 3, reducing insertion resistance. The inclined surface can also provide a certain guiding effect after snap-fit, making the snap-fit ​​between the locking hook 1 and the locking ring 3 tighter and less prone to loosening.

[0028] In one feasible implementation scheme, such as Figures 1 to 3As shown, the connecting piece 2 is a combination of a rectangle and a semicircle. The locking hook 1 is located in the middle of the semicircular part of the connecting piece 2, and the diameter of the semicircular part of the connecting piece 2 is larger than the diameter of the locking hook 1. By designing the shape of the connecting piece 2 as a combination of a rectangle and a semicircle, the position of the locking hook 1 is determined in the middle of the semicircular part of the connecting piece 2 during the modeling process before 3D printing, and it is ensured that the diameter of the semicircular part of the connecting piece 2 is larger than the diameter of the locking hook 1. During printing, the model is formed strictly according to this design. The rectangular and semicircular combination of the connecting piece 2 facilitates connection and fixation with other components and provides stable support for the locking hook 1. The locking hook 1 is located in the middle of the semicircular part, ensuring uniform force distribution. Furthermore, the larger diameter of the semicircular part of the connecting piece 2 than the diameter of the locking hook 1 makes the installation of the locking hook 1 on the connecting piece 2 more secure, enhancing the stability of the overall structure.

[0029] In one feasible implementation scheme, such as Figures 1 to 3 As shown, the inner diameter of the locking ring 3 is slightly larger than the diameter of the locking hook 1, and the outer diameter of the locking ring 3 is the same as the diameter of the semicircular portion of the connecting piece 2. By designing the inner diameter of the locking ring 3 to be slightly larger than the diameter of the locking hook 1, and the outer diameter of the locking ring 3 to be the same as the diameter of the semicircular portion of the connecting piece 2, the dimensional accuracy is strictly controlled during the 3D printing process to ensure that the design requirements are met. The inner diameter of the locking ring 3 being slightly larger than the diameter of the locking hook 1 ensures that the locking hook 1 can smoothly engage with the locking ring 3 to achieve the buckle connection function. The outer diameter of the locking ring 3 being the same as the diameter of the semicircular portion of the connecting piece 2 makes the overall appearance of the buckle more regular and coordinated, facilitating installation and use, and also facilitating cooperation with other components.

[0030] In one feasible implementation scheme, such as Figures 1 to 3 As shown, the button 5 is circular, and its diameter is the same as the outer diameter of the locking ring 3. A circular protrusion 8 is provided on the side of the button 5 facing the locking ring 3, and the diameter of the circular protrusion 8 is slightly smaller than the inner diameter of the locking ring 3. A metal piece 9 is embedded in the center of the side of the button 5 away from the protrusion 8. By designing the button 5 as circular with the same diameter as the outer diameter of the locking ring 3, and designing a circular protrusion 8 on the side of the button 5 facing the locking ring 3 with a diameter slightly smaller than the inner diameter of the locking ring 3, and reserving an inlay groove in the center of the side of the button 5 away from the protrusion 8, the metal piece 9 is inlaid in the groove after 3D printing. The circular button 5 is easy to operate, and the design with the same outer diameter as the locking ring 3 makes the overall structure more compact and beautiful. The cooperation between the circular protrusion 8 and the locking ring 3 can accurately control the movement of the locking hook 1 when the button 5 is pressed, realizing the opening and closing of the buckle. The inlay of the metal piece 9 facilitates cooperation with magnetic components, improving functional expandability.

[0031] Example 2:

[0032] like Figures 4 to 6As shown, this embodiment differs from Embodiment 1 in that it also includes a storage box 10. The storage box 10 includes a lid 101 and a body 102, which are connected by a hinge. A circular hole 103 is provided on the side of the storage box 10 away from the hinge. By assembling the lid 101 and the body 102 into a storage box 10, and setting a hinge structure on one side of the lid 101 and the body 102 to achieve the hinged connection between the two, and machining a circular hole 103 on the side of the storage box 10 away from the hinge, the two are integrally formed according to the design requirements during 3D printing. The hinged connection of the lid 101 and the body 102 facilitates the opening and closing of the storage box 10, making it easy to store and remove the buckles. The circular hole 103 provides space for the installation and use of the buckles, allowing the buckles to be used in conjunction with the storage box 10, increasing the practicality and portability of the product.

[0033] In one feasible implementation scheme, such as Figures 4 to 6 As shown, the lid 101 is inserted into the free end of the connecting piece 2, and the body 102 is inserted into the free end of the connecting piece 6. By fixing the lid 101 and the free end of the connecting piece 2 together, and connecting the body 102 and the free end of the connecting piece 6 in the same way, a firm connection is ensured. The connection between the lid 101 and the connecting piece 2, and between the body 102 and the connecting piece 6, makes the buckle and the storage box 10 a whole, which is convenient for carrying and use. This connection method ensures the stability of the buckle inside the storage box 10, and it is not easy to shake or fall off during use.

[0034] In one feasible implementation scheme, such as Figures 4 to 6 As shown, the hole 103 of the storage box 10 matches the locking ring 3, and the diameter of the hole 103 is slightly larger than the diameter of the locking ring 3. The side of the button 5 away from the protrusion 8 faces outwards from the storage box 10. By precisely machining the hole 103 of the storage box 10 according to the size of the locking ring 3, making its diameter slightly larger than the diameter of the locking ring 3; when installing the buckle, ensure that the side of the button 5 away from the protrusion 8 faces outwards from the storage box 10 for easy operation. The matching of the hole 103 with the locking ring 3 and its slightly larger diameter enable the installation of the buckle with the storage box 10. The setting of the button 5 facing outwards from the storage box 10 facilitates the user's pressing operation of the button 5 to open and close the buckle, improving the convenience of use.

[0035] In one feasible implementation scheme, such as Figures 4 to 6As shown, a decorative sleeve 104 is provided on the outside of the lid 101 and the body 102, and a magnetic decorative piece 105 is provided at the hole 103 of the storage box 10. The magnetic decorative piece 105 is magnetically connected to the metal piece 9. By covering the lid 101 and the body 102 with the decorative sleeve 104, which is fixed by adhesive, and installing the magnetic decorative piece 105 at the hole 103 of the storage box 10, it can be magnetically connected to the metal piece 9 on the button 5. The decorative sleeve 104 enhances the aesthetics and personalization of the storage box 10. The magnetic connection between the magnetic decorative piece 105 and the metal piece 9 not only serves a decorative purpose but also protects the button 5 and the locking ring 3 to a certain extent, preventing dust and impurities from entering. It also facilitates the user's opening and closing of the storage box 10.

[0036] In one feasible implementation scheme, such as Figures 4 to 6 As shown, the locking hook 1, connecting piece 1 2, locking ring 3, connecting piece 2 4, button 5, connecting piece 3 6, protrusion 8, storage box 10, and decorative sleeve 104 are made of elastic plastic through 3D printing. By selecting a suitable elastic plastic as the printing material, the locking hook 1, connecting piece 1 2, locking ring 3, connecting piece 2 4, button 5, connecting piece 3 6, protrusion 8, storage box 10, and decorative sleeve 104 are integrally printed according to the design model. The use of elastic plastic gives the buckle a certain degree of elasticity, which can better adapt to changes in force during the locking and opening process, and is not easily damaged. The integral printing process ensures the connection strength between the components and the stability of the overall structure, improving the quality and service life of the product.

[0037] The 3D-printed integrated buckle provided in this embodiment uses 3D modeling software to construct an integrated model of the hook 1, connecting piece 1 2, locking ring 3, connecting piece 2 4, button 5, connecting piece 3 6, and connecting block 7. The hook 1 is designed as a semi-circle, with a beveled surface machined on the side facing the locking ring 3. The diameter of the beveled surface must match the inner diameter of the locking ring 3. The connecting piece 2 adopts a combination structure of rectangle and semi-circle, with the diameter of the semi-circular part being larger than the diameter of the hook 1. The hook 1 is fixed in the middle of the semi-circle. The outer diameter of the locking ring 3 is the same as the diameter of the semi-circular part of the connecting piece 2, and the inner diameter is precisely designed according to the size of the hook 1. To ensure smooth engagement, button 5 is designed as a circle with a diameter matching the outer diameter of the locking ring 3. A circular protrusion 8 is located in the center facing the locking ring 3, and a slot for a metal piece 9 is reserved on the other side to form a hinge structure between the lid 101 and the body 102. A circular hole 103 is provided on the side away from the hinge to ensure a match with the locking ring 3. Fixed connection structures are provided between the lid 101 and the free end of connecting piece 1 2, and between the body 102 and the free end of connecting piece 3 6. Elastic plastic is used as the printing material to ensure the buckle is elastic, not easily damaged during engagement, and can adapt to deformation under stress. During printing, priority is given to ensuring the bevel of the locking hook 1, the inner diameter of the locking ring 3, and... The molding precision of key parts such as button 5 and protrusion 8 is ensured to avoid poor connection due to printing errors. After printing, the printing support structure is removed, and the beveled surface of locking hook 1 and the edge of connecting piece are polished to ensure a smooth and burr-free surface. A metal piece 9 is embedded in the reserved groove of button 5 and fixed with glue or pressing to enhance the strength and magnetic compatibility of button 5. The box cover 101 and the free end of connecting piece 1 2, and the box body 102 and the free end of connecting piece 3 6 are fixed together by insertion to ensure a firm connection. A magnetic decorative piece 105 is installed at the hole 103 of the storage box 10 to connect with the metal piece 9 of button 5. Alignment forms a magnetic connection, while covering the edge of the hole 103 to enhance aesthetics. The decorative sleeve 104 is fitted onto the outside of the lid 101 and body 102, adding a personalized design and anti-slip effect to the storage box 10. Manual operation button 5 tests the engagement and smooth opening / closing of the hook 1 and ring 3, ensuring the beveled design reduces insertion resistance. The protrusion 8 accurately controls the movement of the hook 1 when pressed. External force is applied to check the connection strength between the connecting piece and hook 1, and between the storage box 10 and the buckle body, ensuring the integrated molding structure is secure. The magnetic decorative piece 105 and the metal piece 9 are tested for adhesion to prevent detachment. Made of elastic plastic using 3D printing, durability is improved, making the buckle's application scenarios wider and more diverse.
