Description

Technical Field

[0001] This utility model relates to the field of watch strap technology, and in particular to an easy-to-disassemble watch strap. Background Technology

[0002] Existing watch chains consist of multiple individual chains. When these individual chains are connected, their heads and tails are typically connected to each other to secure the connection. However, in existing technologies, the heads and tails of individual chains are usually connected by welding or abutting against each other to create a closed loop and prevent the individual chains from falling off.

[0003] However, watch bracelets composed of multiple individual chains have a certain length and can only be worn by users of a specified size. For users whose size is too large or too small, the number of individual chains needs to be increased or decreased to fit different sizes. However, existing technologies use welding or making the head and tail of the individual chains abut against each other to form a closed loop, which makes disassembly and assembly difficult. If it is necessary to change the individual chain from a closed loop state to an open state, the operation involved is difficult and may cause irreversible damage to the individual chain.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides an easy-to-disassemble watch chain, which is simple to disassemble and assemble with the individual chains, and the disassembly and assembly process will not damage the individual chains.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easily detachable watchband includes multiple interconnected single chains, with two adjacent single chains being designated as a first single chain and a second single chain. Both the first and second single chains have recessed portions, and each recessed portion of the first and / or second single chain has an opening. During assembly, the recessed portions of the first and second single chains are pressed together to open the openings, thereby connecting the first and second single chains.

[0008] Furthermore, the recess is formed between the head and tail of the first single chain and between the head and tail of the second single chain.

[0009] Furthermore, both the head and tail of the first and second single chains are conical.

[0010] Furthermore, the diameter of the end of the head near the tail is greater than the diameter of the end of the head away from the tail, and the diameter of the end of the tail near the head is greater than the diameter of the end of the tail away from the head.

[0011] Furthermore, the head and tail of the first single chain and the second single chain are pyramidal or conical.

[0012] Furthermore, the opening is formed between the head and the tail of the first single chain, and / or the opening is formed between the head end and the tail end of the second single chain.

[0013] Furthermore, the width of the opening is 0.3mm-0.35mm, and the axial direction of the head or tail of the first single chain or the second single chain is the width direction of the opening.

[0014] Furthermore, each of the single chains has facets on both sides, and one side of the single chain has two facets, with the two facets located at opposite corners of the single chain.

[0015] Furthermore, the cross-sections on both sides of the single chain are parallel to each other, and the cross-sections on the same side of the single chain are coplanar.

[0016] Compared to existing technologies, the easily detachable watchband provided by this invention includes multiple interconnected single chains. Two adjacent single chains are designated as a first single chain and a second single chain. Both the first and second single chains have recessed portions, and each recessed portion of the first and / or second single chain has an opening. During assembly, the recessed portions of the first and second single chains are pressed together to open the openings, connecting the first and second single chains. This invention allows for quick assembly and disassembly of adjacent single chains through these openings, enabling adjustment of the watchband length. Assembly and disassembly of the single chains is simple and does not damage the chains during the process. Attached Figure Description

[0028] like Figure 1 and Figure 2 As shown, this utility model provides an easy-to-assemble watch chain, comprising multiple interconnected single chains. Two adjacent single chains are respectively a first single chain 1 and a second single chain 2. Both the first single chain 1 and the second single chain 2 are provided with a recess 3. The recess 3 of the first single chain 1 and / or the second single chain 2 is provided with an opening 4. During assembly, the recesses 3 of the first single chain 1 and the second single chain 2 are pressed against each other to open the opening 4, thereby connecting the first single chain 1 and the second single chain 2.

[0029] It is understood that the recesses 3 on the first single chain 1 and the second single chain 2 may both have the opening 4, or the recesses 3 on either the first single chain 1 or the second single chain 2 may have the opening 4. Through the opening 4, the first single chain 1 and the second single chain 2 can be fastened together. By simply aligning the recesses 3 on the first single chain 1 and the second single chain 2 and prying them outwards, the first single chain 1 and the second single chain 2 can be easily separated.

[0030] Compared with the prior art, the technical solution of this utility model enables the quick assembly and disassembly of two adjacent single chains through the opening 4, thereby achieving the adjustment of the watch chain length. The assembly and disassembly of the single chains is simple and will not damage the single chains during the assembly and disassembly process, resulting in a better user experience.

[0031] Furthermore, the recessed portion 3 is formed between the head and tail of the first single chain 1 and between the head and tail of the second single chain 2. It is understood that the recessed portion 3 is formed between the head and tail of the first single chain 1 and between the head and tail of the second single chain 2. Taking the manufacture of the first single chain 1 as an example, the first single chain 1 is formed by bending and folding a straight bar to form a closed loop. That is, the head and tail of the bar are the head and tail of the first single chain 1. When the head and tail of the first single chain 1 form a closed loop, the recessed portion 3 is formed between them. The recessed portion 3 facilitates the positioning of the first single chain 1 and the second single chain 2 during assembly and disassembly, allowing them to quickly enter the designated assembly / disassembly position, effectively improving the efficiency of assembly and disassembly.

[0032] Furthermore, the head and tail of the first single chain 1 and the second single chain 2 are both conical, which facilitates the quick engagement of the recessed portions 3 of the first single chain 1 and the second single chain 2 when they are assembled or disassembled. Subsequently, only a small amount of external pulling force is needed to separate the first single chain 1 and the second single chain 2 through the opening 4.

[0033] Specifically, the diameter of the end of the head near the tail is greater than the diameter of the end of the head away from the tail, and the diameter of the end of the tail near the head is greater than the diameter of the end of the tail away from the head, so as to facilitate the separation of the first single chain 1 and the second single chain 2 through the opening 4, thereby achieving the effect of disassembly.

[0034] Furthermore, the head and tail of the first single chain 1 and the second single chain 2 are pyramidal or conical. It is understood that the pyramidal or conical shape of the head and tail facilitates the rapid positioning of the recessed portion 3 of the first single chain 1 and the second single chain 2, and also allows for rapid separation of the first single chain 1 and the second single chain 2 through the opening 4.

[0035] Furthermore, the opening 4 is formed between the head end and the tail end of the first single chain 1, and / or between the head and the tail of the second single chain 2. It should be noted that since the head and tail are arranged in a pyramidal or conical shape, i.e., the opening 4 is located between the head and the tail, it ensures that the contact area on both sides of the opening 4 is minimized, thus enabling the first single chain 1 and the second single chain 2 to separate through the opening 4.

[0036] In one embodiment, the recessed portion 3 on the first single chain 1 is provided with the opening 4, while the recessed portion 3 on the second single chain 2 is not provided with the opening 4. That is, the second single chain 2 can be separated from the first single chain 1 through the opening 4 on the recessed portion 3 of the first single chain 1, thereby achieving the separation of the first single chain 1 and the second single chain 2.

[0037] It should be noted that a cylinder is provided at the lowest point of the recess 3 of the second single chain 2, that is, the cylinder is located at the connection between the head and tail of the second single chain 2. The width of the opening 4 is equal to or less than the diameter of the cylinder to prevent the opening 4 from separating from the cylinder, which would cause the first single chain 1 to separate from the second single chain 2.

[0038] Furthermore, the width of the opening 4 is 0.3mm-0.35mm, which provides better assembly and disassembly. The axial direction of the head or tail of the first single chain 1 or the second single chain 2 is the width direction of the opening 4.

[0039] Furthermore, each of the single chains has a facet 5 on both sides, and one side of the single chain has two facets 5, with the two facets 5 located at opposite corners of the single chain. This prevents the chain from bulging excessively and causing discomfort when wearing the watch chain.

[0040] Furthermore, the cut surfaces 5 on both sides of the single chain are parallel to each other, and the cut surfaces 5 on the same side of the single chain are coplanar, so that the watch chain can be placed horizontally on the table, making it convenient to store and place the watch chain.

[0041] In summary, the easily detachable watchband provided by this utility model features a recessed portion that facilitates positioning when the first and second single chains are detached or assembled, allowing them to quickly enter the designated detachment / assembly positions and effectively improving efficiency. The head and tail are pyramidal or conical in shape, both contributing to the rapid positioning of the recessed portions of the first and second single chains and facilitating quick separation through the opening. Furthermore, the opening allows for rapid detachment / assembly of adjacent single chains, enabling adjustment of the watchband length. The detachment / assembly of single chains is simple and does not damage them, resulting in a superior user experience.

[0042] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
