AI Technical Summary
[0003]这种结构有一个显著缺点，因为负责固定表带尾部的那个箍圈是活动的，可以自由移动，而人手部的活动非常频繁，箍圈经常在手腕的活动下与其他物体摩擦接触，极易产生滑动移位，经常会完全滑出表带尾部一点都起不到固定表带尾部的作用，表带尾部没有箍圈固定就会翘起，既不美观，翘起的表带尾也容易刮到其他物品，使用感受非常不好
本实用新型的显著特点，就是将表带常规设计的内径较大的活动尾箍圈，改进为内径较小的能箍紧表带的作为尾箍圈的第二箍圈，并利用短带的宽窄差或者厚薄差进一步限制第二箍圈的移动，达到箍紧长带尾部，不让长带尾部随意翘起的目的。

Description
Technical Field
[0001] This utility model belongs to the field of watch strap manufacturing technology, specifically relating to a leather watch strap with a tail ring tightening anti-slip self-locking structure. Background Technology
[0002] Leather watch straps are a common type of watch strap. The main body of the strap, the strap itself, is divided into two sections: a short strap and a long strap. The most common design is as follows: one end of the short strap connects to one end of the watch case, and the other end has a buckle, such as a pin buckle or butterfly buckle. Near the buckle, there are usually two loops to secure any excess strap after it passes through the buckle, preventing it from sticking up unsightly. One loop is sewn in place near the buckle, while the other is free to move. One end of the long strap connects to the other end of the watch case, and this other end, the strap tail, is usually pointed to make it easier to pass through the buckle and loops. When wearing a watch, after the long strap passes through the buckle and is secured, any excess strap is bent and passed through the fixed loop. Because wearers' wrists vary in size, there may be a section of the long strap that is longer or shorter than the fixed loop; this section is then secured by the movable loop.
[0003] This structure has a significant drawback: the hoop that secures the end of the watchband is movable and can move freely. Since the human hand moves very frequently, the hoop often rubs against other objects during wrist movements, making it prone to sliding and shifting. It often slides completely off the end of the watchband and fails to secure it at all. Without the hoop to hold it in place, the end of the watchband will stick up, which is not only unsightly but also makes it easy to snag other items, resulting in a very poor user experience.
[0004] To address the shortcomings of existing structural designs, this utility model provides a leather watch strap with a tail ring-type anti-slip self-locking structure that is reasonably designed, simple in structure, provides a good user experience, and does not increase production costs. Utility Model Content
[0005] The purpose of this utility model is to provide a leather watch strap with a tail ring tightening anti-slip self-locking structure, which can realize the tail ring tightening anti-slip self-locking function.
[0006] The specific technical solution adopted by this utility model is as follows: A leather watch strap with a self-locking anti-slip structure featuring a tail loop fastening mechanism includes a long strap and a short strap. One end of the short strap is connected to one end of the watch case, and a buckle is installed at the other end. Two loops are provided on the short strap. One end of the long strap is connected to the other end of the watch case, and the tail of the other end of the long strap is adapted to the buckle. The tail of the other end of the long strap has a triangular tip structure. Both loops are movably fitted onto the short strap. The two loops are a first loop and a second loop. The first loop is closer to the buckle, and the second loop, as a tail loop, is closer to the watch case. The inner diameter of the first loop is larger than the inner diameter of the second loop, and the inner diameter of the second loop is smaller than the total circumference of the short and long straps overlapping at the base of the triangular tip of the long strap.
[0007] Preferably, the long strap and the short strap are made of leather.
[0008] Preferably, the width of the long strip decreases sequentially from the root to the end, and the width of the short strip decreases sequentially from the root to the end.
[0009] Preferably, the thickness of the short strip decreases sequentially from the root to the end.
[0010] The technical effects achieved by this utility model are as follows: The most significant feature of this invention is that the conventional watchband design with a large inner diameter movable end ring is improved into a second end ring with a smaller inner diameter that can tighten the watchband. The movement of the second end ring is further restricted by the width or thickness difference of the short band, so as to tighten the end of the long band and prevent it from sticking up at will.
[0011] This utility model provides a leather watch strap with a tail ring clamping anti-slip self-locking structure that is reasonably designed, simple in structure, provides a good user experience, and does not increase production costs. Attached Figure Description

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example 1
[0015] like Figure 1 as well as Figure 4 As shown, a leather watch strap with a self-locking anti-slip structure featuring a tail ring includes a long strap 1 and a short strap 2. The root of one end of the short strap 2 is connected to one end of the watch case 3, and a buckle 4 is installed at the other end of the short strap 2. Two rings are provided on the short strap 2. The root of one end of the long strap 1 is connected to the other end of the watch case 3, and the tail of the other end of the long strap 1 has a triangular pointed structure. The tail of the other end of the long strap 1 is adapted to the buckle 4. The surface area of the longitudinal section of the short strap 2 decreases sequentially from the root to the end. Both rings are movably fitted on the short strap 2. The two rings are a first ring 5 and a second ring 6. The first ring 5 is close to the buckle 4, and the second ring 6 is close to the watch case 3.
[0016] Preferably, the long strap 1 and the short strap 2 are made of leather. This utility model is compatible with leather watch straps, and the friction and expansion characteristics of leather watch straps can enhance the locking effect at the base.
[0017] Preferably, the width of the second band 6 is smaller than the width of the first band 5, thereby making the inner diameter of the first band 5 larger than the inner diameter of the second band 6. The inner diameter of the second band 6 is smaller than the total circumference at the root of the triangular tip after the long band 1 and the short band 2 overlap. When wearing the watch, the second band 6 can only be inserted into the second band 6 at the triangular tip of the end of the long band 1. Specifically, only the triangular tip of the end of the long band 1 can be inserted into the second band 6. Figure 4 As shown, when corresponding to the different arm thicknesses of different users, first slide the second hoop 6 on the short strap 2 to the corresponding position, after the buckle 4 fastens the long strap 1, insert the triangular tip of the end of the long strap 1 into the second hoop 6 and then tighten the triangular tip of the end of the long strap 1.
[0018] Preferably, the width of the long strip 1 decreases sequentially from the root to the end, and the width of the short strip 2 decreases sequentially from the root to the end.
[0019] In this embodiment, since the long strap 1 and short strap 2 of a typical leather watch strap are generally wider at the end near the watch case 3 than at the end near the buckle 4 (e.g., the end near the watch case 3 is 20mm, then the end near the buckle 4 is about 18mm or 19mm), they generally taper gradually, forming a trapezoidal shape. This design makes both loops movable, and the two loops have different inner diameters: the first loop 5 has a larger inner diameter, and the second loop 6 has a smaller inner diameter. The larger loop, the first loop 5, is closer to the buckle 4, while the smaller loop, the second loop 6, is further away from the buckle 4; that is, the end loop of the watch strap. After the long strap 1 passes through the buckle 4, the excess portion can easily pass through the first loop 5. The inner diameter of the second loop 6, as the end loop, is designed to be relatively small, with the standard being that only the pointed end of the long strap 1 can pass through the second loop 6. The second loop 6 plays a major role in fixing the triangular tip of the long strap 1, while the first loop 5, as the larger loop, only plays an auxiliary role.
[0020] This design fully utilizes the gradual change in size at both ends of the short strap 2, that is, the wider it is as far away from the buckle 4, to restrict the movement of the second hoop 6 towards the wider part of the short strap 2. When the pointed part of the long strap 1 is inserted into the second hoop 6, the overlapping part of the pointed parts of the short strap 2 and the long strap 1 tightens the second hoop 6. At the same time, the second hoop 6 also tightens the overlapping part of the long strap 1 and the short strap 2. During the wearing process, even if there is an external force that causes the second hoop 6 to move to both sides, the base of the short strap 2 becomes wider on one side, and the pointed end of the long strap 1 becomes wider on the other side. Both sides play a limiting role on the second hoop 6, generating resistance to the movement of the second hoop 6 and restricting the second hoop 6 to move only within a very small range. The second hoop 6 achieves self-locking, thereby providing a reliable fixing effect on the end of the strap. Example 2
[0021] like Figure 2 As shown, the difference from Embodiment 1 is that the widths of the long strap 1 and the short strap 2 remain unchanged. Instead, the thickness of the short strap 2 decreases sequentially from the root to the end. Therefore, in addition to using the width difference of the short strap 2 to restrict the movement of the second hoop 6, the thickness difference of the short strap 2 can also be used to restrict the movement of the second hoop 6. That is, the short strap 2 is made thinnest near the buckle 4 and thicker further away from the buckle 4. When the pointed part of the long strap 1 is inserted into the second hoop 6, the second hoop 6 also achieves self-locking because it cannot move towards the thicker part of the short strap 2. The two methods of achieving self-locking of the tail hoop using the width difference of the short strap 2 and achieving self-locking of the tail hoop using the thickness difference of the short strap 2 can be used individually. Example 3
[0022] like Figure 3 As shown, the self-locking of the tail ring can be achieved by using the width difference of the short belt 2 and the thickness difference of the short belt 2. These two methods can also be used in combination. That is, a short belt 2 can have both width and thickness differences, and the combination can also achieve a very good self-locking effect.
[0023] In this utility model, embodiments one to three are preferred implementations. Some leather watch straps need to be designed as straight; that is, except for the pointed end of the strap, all parts of the strap body are of uniform width and thickness. For example, in ultra-thin leather watch straps, the short strap 2 of this type of leather watch strap cannot use the difference in width and thickness to restrict the movement of the second hoop 6, which is used as the end ring. However, because the inner diameter of the second hoop 6 is designed to be small, it has a frictional force when it is fitted onto the short strap 2 and is not easy to slip. When the pointed end of the long strap 1 is inserted into the second hoop 6, the overlapping part of the pointed end of the short strap 2 and the long strap 1 will tighten the second hoop 6. At the same time, the second hoop 6 will also tighten the overlapping part of the long strap 1 and the short strap 2. The second hoop 6 cannot move in a large range, and its fixing effect on the end of the long strap 1 is much better than the movable end ring of other ordinary leather watch straps.
[0024] The most significant feature of this invention is that the conventional design of the movable end ring of the leather watch strap, which has a relatively large inner diameter, is improved into a second ring 6 with a smaller inner diameter that can tighten the leather watch strap. Furthermore, the width or thickness difference of the short strap 2 is used to further restrict the movement of the second ring 6, thereby achieving the purpose of tightening the end of the long strap 1 and preventing the end of the long strap 1 from sticking up at will.
[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
