Description

Technical Field

[0001] This utility model relates to the technical field of bra strap buckle assembly, specifically to a quick-change structure for the insert blade of a bra strap buckle machine. Background Technology

[0002] "Shoulder strap" generally refers to clothing-related parts such as shoulder straps, back straps, and shoulder straps, like those on backpacks, tops, or skirts. The production process of shoulder straps typically includes multiple steps such as length cutting, length inspection, perforation, and welding. Each step plays a crucial role in the quality and function of the shoulder strap. In the perforation process, a mechanism drives a cutting tool to contact the shoulder strap, ultimately folding the long strip of strap in half and inserting it into the buckle. However, during the folding process, depending on the width requirements of the shoulder strap and the buckle, simply inserting the cutting tool alone often fails to meet the process requirements. For example, if the shoulder strap width is too wide, the cutting tool can only contact a small portion of the strap during folding, resulting in an uneven inward contraction of the outer part. Conversely, if the width of the shoulder strap and the corresponding buckle is too small, and the cutting tool is too large, the buckling process cannot be completed. Utility Model Content

[0022] refer to Figure 1 , Figure 2 As shown in the accompanying drawings and specific embodiments, further explanation will be provided below:

[0023] The bra strap fastening machine has a quick-change insert mechanism, including a fixing block 1 and a shoulder screw 2 that is detachable from the fixing block 1. When the shoulder screw 2 is assembled on the fixing block 1, there is an installation gap 3 between the nut on the shoulder screw 2 and the fixing block 1. The assembly includes an assembly piece 4 and a fastening piece 5. The assembly piece 4 has a first hole 6 for the nut on the shoulder screw 2 to pass through and a second hole 7 that can be placed at the installation gap 3. The first hole 6 and the second hole 7 are in a connected state. After the assembly piece 4 enters the nut on the shoulder screw 2 through the first hole 6 and contacts the fixing block 1, it moves to move the second hole 7 on the assembly piece 4 to the installation gap 3 between the nut and the fixing block 1. At this time, the fastening piece 5 is exposed outside the fixing block 1 and is used to abut the shoulder strap.

[0024] The technical solution is designed to be assembled from two parts: a fixing block 1 and an assembly body. The purpose is to facilitate the quick disassembly and assembly of the integrated assembly piece 4 and the fastening piece 5 on the fixing block 1.

[0025] Specifically, regarding the structure of the fixing block 1, there are two threaded holes on the fixing block 1 as shown in the figure (the positions are staggered left and right), and the shoulder screw 2 is threaded onto it. The size of the installation gap 3 between the nut on the shoulder screw 2 and the fixing block 1 can be adjusted by adjusting the forward and reverse rotation of the thread.

[0026] To facilitate the operator's operation, the outer surface of the nut on the shoulder screw 2 is provided with a strip groove 8, which makes it easy to use tools (such as wrenches, pliers, etc.) to tighten or loosen the nut, increasing the convenience of operation and making it easier to adjust the size of the installation gap 3.

[0027] For the integrally molded assembly piece 4 and the through-fastening piece 5, the assembly piece 4 is provided with a first hole 6 for the nut on the shoulder screw 2 to pass through and a second hole 7 for placement in the installation gap 3. The first hole 6 and the second hole 7 are in a connected state. Specifically, the diameter of the first hole 6 is larger than the diameter of the nut on the shoulder screw 2, and the diameter of the second hole 7 is smaller than the diameter of the nut on the shoulder screw 2 but larger than the diameter of the stud on the shoulder screw 2. The installation method is that after the assembly piece 4 enters the nut on the shoulder screw 2 through the first hole 6 and contacts the fixing block 1, the second hole 7 on the assembly piece 4 is moved to the installation gap 3 between the nut and the fixing block 1. At this time, the through-fastening piece 5 is exposed outside the fixing block 1 and is used to abut the shoulder strap position, thereby facilitating the fastening operation.

[0028] Meanwhile, the fixing block 1 is also provided with an adsorption magnet 12 for magnetic attraction with the assembly piece 4, and the integrally formed assembly piece 4 and the buckle piece 5 are made of iron material that can be attracted to the adsorption magnet 12. This can further strengthen the assembly connection between the assembly piece 4 and the fixing block 1 (the adsorption magnet 12, the first hole 6, and the second hole 7 are arranged in two staggered sets as shown in the figure to ensure the stability of the assembly).

[0029] A side plate 9 is provided on one side of the fixing block 1, so that the assembled assembly can be assembled with the fixing block 1 by aligning the side plate 9 with the fixing block 1.

[0030] In summary, the working principle of this utility model is as follows: the operator adjusts the size of the installation gap 3 along the strip groove 8 using a tool, thereby loosening or tightening the assembly. First, the assembly piece 4 is inserted through the first hole 6 to the side near the fixing block 1, then upwards as shown in the figure, so that the second hole 7 is at the same level as the nut, and then the shoulder screw 2 is tightened to complete the assembly. This method allows for quick replacement of assemblies with buckle pieces 5 of different widths to accommodate shoulder straps and buckles of different widths.

[0031] Furthermore, an extension block 10 is provided on the fixed block 1, and an assembly hole 11 is provided for the extension block 10 to connect with the external components. The fixed block 1 and the extension block 10 are integrally formed into an L-shape. The purpose of the extension block 10 is mainly to facilitate connection with other mechanisms such as telescopic mechanisms, thereby driving the fixed block 1 to move. The assembly hole 11 is vertically located on the upper surface of the extension block 10, and the shoulder screw 2 is horizontally located on the surface of the fixed block 1, so that the connection is direct and more convenient in the drive connection.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
