Description

Technical Field

[0001] This invention belongs to the field of belt buckle technology, specifically relating to a tail clip for belt buckles and a belt buckle having the same. Background Technology

[0002] Belts have become a fashion statement; a close look at international fashion shows reveals that designers are inseparable from them. This shows that belts now serve more than just a waist-cinching function; with people's pursuit of fashion, belts have become a highlight of the overall outfit. Modern belts generally consist of a belt body and a buckle. Some belts also have loops. One end of the belt body passes through the buckle and is then secured using the loops on the buckle or clothing. This creates an overlap between the buckle and the loop. Sliding the loop along the belt body changes the position of the loop's end, thus altering the length of the overlap and adjusting the overall length of the belt.

[0003] Currently, the head of the belt body is typically fixed to the buckle using a tail clip with a retaining pin. This means the length of the belt body is fixed after connection. While the tail of the belt body can be adjusted by changing its position relative to the buckle, the overlap is usually limited for aesthetic reasons. Furthermore, the length of the fixing holes or slots on the belt is generally limited. This forces users to trim the head of the belt body upon receipt to suit their needs, resulting in material waste. Additionally, not everyone can adjust the length accurately, leading to occasional cutting errors or inaccuracies. Multiple cutting operations are required, which reduces the user experience. Therefore, to accommodate people of different body types and reduce waste, manufacturers and retailers often need to prepare belts of various lengths and sizes. However, a certain quantity of each length and size needs to be prepared, which leads to several problems: first, it increases inventory and costs; second, it requires separate storage of belts of different lengths to avoid mixing, resulting in storage difficulties and large space requirements; third, it is easy to package the wrong length during the packaging process; and fourth, if certain lengths of belts are not sold, it can easily lead to inventory backlog and increased costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technology and provide a tail clip for belt buckles. This tail clip can fix the beginning of the belt and make it easy to adjust its length at the beginning of the belt without cutting or adjusting the belt.

[0005] In a first aspect, to solve the above-mentioned technical problems, the present invention provides a tail clip for a belt buckle, comprising: The fixing seat has a through groove at one end for the belt to pass through and out; A locking element, which is rotatably and slidably disposed on the fixed base and through which a belt passing through the through slot is wound in the opposite direction; When the locking member moves relative to the fixed seat, the locking member moves closer to or further away from the through groove to clamp or loosen the belt that is threaded through the through groove.

[0006] Furthermore, the fixing base includes: Base; A limiting rod is provided on one side of the base and integrally formed with the base, and a through groove is formed between the limiting rod and the base.

[0007] Furthermore, a hollow groove is provided on the base at a position corresponding to the limiting rod.

[0008] Furthermore, the fixing base or locking member is provided with an oblong hole, and one end of the locking member is movably connected to the fixing base through a rotating shaft passing through the oblong hole, so that the locking member can be rotatably and slidably mounted on the fixing base.

[0009] Furthermore, the locking member is a U-shaped rod, with its two arm ends respectively positioned on both sides of the fixed base; the waist-shaped hole is provided on the fixed base so that the rotating shaft can be rotatably and slidably mounted on the fixed base; and both ends of the rotating shaft protrude from the fixed base and are respectively connected to the two arm ends of the locking member, thereby forming a through hole between the locking member and the fixed base for the belt to pass through.

[0010] Furthermore, the rotating shaft passes through the fixed base, and both ends of the rotating shaft protrude from the fixed base; the locking member is a U-shaped rod, with the two arm ends of the locking member respectively placed on both sides of the fixed base, and each of the two arm ends of the locking member is provided with the waist-shaped hole. The two ends of the rotating shaft are rotatably and slidably inserted into the waist-shaped holes of the two arm ends, thereby forming a through hole between the locking member and the fixed base for the belt to pass through.

[0011] Furthermore, the fixed seat has a connecting part at one end away from the through groove; the locking member has a through hole for the belt to pass through, and one end of the locking member has two pivot ears located on both sides of the connecting part respectively. The rotating shaft passes through the pivot ears and the connecting part, and the connecting part or pivot ears have waist-shaped holes for the rotating shaft to pass through.

[0012] Furthermore, the fixed seat has a connecting part on each side of the end away from the through groove; the locking member has a through hole for the belt to pass through, and one end of the locking member has at least one pivot lug located between the two connecting parts. The rotating shaft passes through the connecting part and the pivot lug, and the connecting part or the pivot lug has a waist-shaped hole for the rotating shaft to pass through.

[0013] Furthermore, the width of the fixing seat is the same as the width of the locking member, and the length of the through groove is the same as the length of the through hole.

[0014] In a second aspect, the present invention also provides a belt buckle, including a buckle body and a tail clip as described in any of the first aspects; wherein, the end of the fixing seat away from the through groove is rotatably or fixedly connected to the buckle body.

[0015] Furthermore, the buckle body has a through opening, and the end of the fixed seat away from the through groove is rotatably disposed in the opening via a movable rod. The rotating shaft is located between the movable rod and the through groove, and the locking member is located on the side of the fixed seat away from the buckle body. A first insertion groove and a second insertion groove are respectively formed between the movable rod and the two ends of the opening for the tail end of the belt to pass through. A needle rod is rotatably disposed in the middle of the movable rod, and the end of the needle rod away from the movable rod overlaps the outer side of one end of the buckle body.

[0016] Furthermore, the end of the fixed seat away from the through groove is rotatably located inside one end of the buckle body via a movable rod. The rotating shaft is located between the movable rod and the through groove, and the locking member is located on the side of the fixed seat away from the buckle body. A fixing groove is formed between the buckle body and the fixed seat for the tail end of the belt to pass through. The end of the fixed seat away from the through groove is provided with several fixing teeth perpendicular to the insertion direction of the fixing groove.

[0017] Furthermore, the buckle body is provided with a U-shaped groove, and the end of the fixing seat away from the through groove is rotatably disposed inside the opening end of the U-shaped groove via a rotating shaft. The outer side of the opening end of the buckle body is integrally formed with a U-shaped rod connecting the two sides of the opening end, and a limiting groove for the waist belt to pass through is formed between the U-shaped rod and the tail clip; a needle rod is rotatably disposed in the middle of the rotating shaft, and the movable end of the needle rod overlaps the outer side of the end of the U-shaped groove away from the opening.

[0018] Furthermore, the end of the fixed seat away from the through groove is rotatably mounted on one end of the buckle body via a rotating shaft, and the other end of the buckle body is provided with an automatic buckle. Gaps are formed between both ends of the buckle body and the automatic buckle and the tail clip for the belt to pass through.

[0019] The present invention has the following beneficial effects: In this invention, the end clip can fix the beginning of the belt and facilitate the adjustment of its length at the beginning. Specifically, during use, the beginning of the belt passes inward through the slot, wraps around the locking element in the opposite direction, and then exits through the slot. The length of the belt can be adjusted by changing the length of the belt exiting the slot. This eliminates the need for tailoring to fit different body types, and manufacturers and retailers only need to prepare belts of one length and size, thus solving various problems associated with preparing belts of different lengths in existing technologies.

[0020] Secondly, the tail clip structure allows the locking element to rotate and slide relative to the fixed seat. This facilitates the belt's insertion and allows it to pass through the locking element. During use, as the belt is tightened, the locking element moves outward under the pulling force, gradually approaching the through slot, thus reducing the gap between the locking element and the through slot and clamping the belt. This achieves a tightening effect, ensuring no loosening occurs during use. When it's necessary to loosen or adjust the belt length, simply push the belt into the through slot. The locking element moves away from the through slot and rotates outward under the pushing force (i.e., rotates away from the fixed seat). At this point, the locking element and the through slot move away from each other, easily loosening the belt and adjusting its length without the need for complicated, repeated pulling and pulling motions. The entire locking and loosening adjustment process is simple and convenient.

[0021] Furthermore, as an independent fixing structural unit, this tail clip can be applied to different types of belt buckles, such as pin buckles, plate buckles, and automatic buckles, thus improving the application range and versatility of the tail clip.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0024] To better understand the technical content of the present invention, the present invention will be further introduced and described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the use of terms such as "first" and "second" in the text is for distinguishing different components, and does not represent the order of events, nor does it limit "first" and "second" to different types.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1 like Figures 1 to 3As shown in the figure, the tail clip 100 for a belt buckle in this embodiment includes a fixed base 1 and a locking member 2 movably connected to the fixed base 1 at one end. One end of the fixed base 1 is provided with a through groove 10 for the belt to pass through and exit. The locking member 2 is rotatably and slidably set on the fixed base 1 and allows the belt that passes through the through groove 10 to pass through in the opposite direction. That is, the belt that passes through the through groove 10 can pass through the locking member 2 in the opposite direction, and then the belt exits from the through groove 10. That is, the belt enters and exits in the through groove and passes through the locking member, thereby fixing the beginning of the belt. The length of the belt can be adjusted by adjusting the length of the belt that exits from the through groove. This allows the length of the belt to be easily adjusted at the beginning of the belt, so that the length of the belt does not need to be cut to adapt to different body shapes. When manufacturers and retailers prepare belts, they only need to prepare belts of one length and size, thereby solving various problems existing in the prior art when it is necessary to prepare belts of different lengths.

[0027] Specifically, such as Figures 1 to 3 As shown, the locking element 2 is located on the inner side of the fixing seat so that the first end of the belt that passes through it is located on the inner side of the belt close to the body when in use. This allows the outer belt to cover it, preventing it from being exposed and affecting the aesthetics when in use. The outer belt part and the body can also be used to clamp the inner belt part together, preventing it from falling off or sticking up during use.

[0028] like Figures 1 to 3 As shown, to facilitate better and more convenient locking and unlocking of the belt, after the locking member 2 rotates and / or slides (i.e., moves) relative to the fixed seat 1, the free end of the locking member 2 (i.e., the end away from the rotatable connection with the fixed seat) approaches or moves away from the through groove 10 to clamp or unlock the belt passing through the through groove 10. That is, when the free end of the locking member 2 rotates toward the inner side of the fixed seat, it gradually approaches the position of the through groove 10, eventually making the locking member 2 located inside the through groove 10, thus forming a gap between the locking member 2 and the through groove 10 to clamp the belt. At this time, when the belt is pulled outward, the locking member 2 moves outward under the action of the pulling force and gets closer and closer to the through groove, thereby gradually reducing the gap between the locking member 2 and the through groove and further clamping the belt 110 (e.g., as shown in the diagram). Figure 4 As shown), this achieves a tightening effect as it is pulled, ensuring that it will not loosen during use. When it is necessary to loosen or adjust the length of the belt, simply push the belt 110 into the through groove. Under the action of the thrust, the locking member 2 moves away from the through groove and rotates outward (i.e., rotates away from the fixed seat). At this time, the locking member 2 and the through groove move away from each other (as shown). Figure 5 As shown in the image, it is easy to loosen the belt and adjust its length without the need for complicated repeated pulling and pulling of the belt. The entire locking and loosening adjustment process is simple and convenient.

[0029] In one embodiment, such as Figures 1 to 3 As shown, the fixed base 1 includes a base 11 and a limiting rod 111 integrally formed on one side of the base. A through groove 10 is formed between the limiting rod 111 and the fixed base 1.

[0030] In one embodiment, such as Figures 1 to 3 As shown, a hollow groove 12 is provided on the base 11 at a position corresponding to the limiting rod 111. The hollow groove 12 serves two purposes: first, it creates a clearance notch at the through groove 10, which effectively expands the width of the through groove, making it easier for the belt to be inserted and removed from the through groove. This avoids the belt being difficult to insert when the width of the through groove is similar to the thickness of the belt. Second, it also reduces the sliding friction between the belt and the fixing seat, making it easier for the user to push the belt inward to loosen it.

[0031] Specifically, such as Figures 1 to 3 As shown, due to the hollowed-out groove, the front end of the base 11 protrudes out of the through groove 10. One end of the protruding through groove 10 is misaligned with the limiting rod 111 to form a pressure rod 13. The pressure rod 13 can flatten the outer waist belt part, thus flattening the waist belt.

[0032] In a practical application, the width of the hollow groove 12 can be made greater than the width of the limiting rod 111, so that the waist belt has a larger range of motion when passing through the through groove.

[0033] In one embodiment, such as Figures 1 to 3 As shown, a waist-shaped hole 14 is provided through the base 11. The length of the waist-shaped hole 14 extends along the front and back of the fixed base 1. That is, one end of the waist-shaped hole 14 is close to the through groove 10, and the other end is away from the through groove 10. One end of the locking member 2 is connected to the base 11 through a rotating shaft 3 that passes through the waist-shaped hole 14. The width and length of the waist-shaped hole 14 are both greater than the outer diameter of the rotating shaft 3, so that the rotating shaft 3 can be rotatably and slidably passed through the waist-shaped hole 14, thereby allowing the locking member 2 to be rotatably and slidably mounted on the base 11.

[0034] Specifically, such as Figures 1 to 3 As shown, the locking member 2 is a U-shaped rod. The two arm ends of the locking member 2 are respectively placed on both sides of the base 11. Both ends of the rotating shaft 3 protrude from the base 11 and are movably or fixedly connected to the two arm ends of the locking member 2, that is, both arm ends of the locking member 2 are provided with through holes for the rotating shaft 3 to pass through; and the locking member 2 utilizes the U-shaped structure to form a through hole 20 between the locking member 2 and the base 11 for the belt to pass through.

[0035] In a practical application, the diameter of the through holes on the two arm ends of the locking component is equal to or slightly larger than the outer diameter of the rotating shaft.

[0036] Optionally, the rotating shaft is preferably a pin, and a limiting part with an outer diameter larger than the through hole is provided at both ends of the rotating shaft, so as to limit the locking member on the fixed seat.

[0037] In other embodiments, the maximum width of the fixing seat is the same as the maximum width of the locking member, and the length of the through groove is the same as the length of the through hole. That is, the fixing seat has recessed clearance positions on both sides at the end away from the through groove to accommodate the end of the locking member arm.

[0038] Example 2 like Figures 1 to 8 As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 1.

[0039] Specifically, such as Figures 6 to 8 As shown, the belt buckle also includes a buckle body 200, which has openings extending through both the inner and outer sides. One end of the fixing base 1 away from the through groove 10 is rotatably positioned within the opening via a movable rod 201. A rotating shaft 3 is located between the movable rod 201 and the through groove 10, and a locking member 2 is located on the side of the fixing base 1 away from the buckle body 200 (i.e., the inner side). A first insertion groove 204 and a second insertion groove 205 are formed between the movable rod 201 and the two ends of the opening, respectively, for the tail end of the belt to pass through. The first insertion groove 204 is positioned away from the tail clip 100. The tail clip 100 is located inside the second insertion groove 205. A needle bar 300 is rotatably provided in the middle of the movable rod 201. One end of the needle bar 300 away from the movable rod 201 is attached to the outer side of one end of the buckle body, and the needle bar 300 is located outside the first insertion groove. That is, when in use, the tail end of the belt passes through the first insertion groove 204 from the inside to the outside, and then is inserted into the fixing hole on the belt through the needle bar 300. Then the tail end of the belt passes through the second insertion groove 205 from the outside to the inside, so that the tail end of the belt is located outside the tail clip 100.

[0040] It is understandable that, in order to allow one end of the needle bar 300 to be rotatably located in the middle of the movable rod 201, a notch for accommodating the end of the needle bar 3 is provided in the middle of the end of the fixed seat away from the through groove 10.

[0041] It is understandable that, in order to form the first insertion slot and the second insertion slot, the movable rod 201 is rotatably positioned at or near the center of the opening.

[0042] Example 3 like Figures 9 to 13 As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 1.

[0043] Specifically, such as Figures 9 to 13As shown, the belt buckle also includes a buckle body 200. One end of the fixing base 1, away from the through groove 10, is rotatably mounted on the inner side of one end of the buckle body 200 via a movable rod 201. A rotating shaft 3 is located between the movable rod 201 and the through groove 10, and a locking member 2 is located on the side of the fixing base 1 away from the buckle body 200 (i.e., the inner side). A fixing groove 202 is formed between the buckle body 200 and the fixing base 1 for the end of the belt to pass through. Several fixing teeth 1 perpendicular to the insertion direction of the fixing groove 202 are provided on the end of the fixing base 1 away from the through groove 10. 01. In use, first rotate the buckle body 200 outward to open it, so that the end of the belt can be inserted into the fixing groove 202. After the end of the belt is inserted into the fixing groove 202, rotate the buckle body 200 to close it. The fixing teeth 101 exert a strong clamping force on the end of the belt inserted into the fixing groove 202, thereby fixing the end of the belt and preventing the belt from coming loose due to insufficient clamping force. The interaction force between the belt and the fixing teeth also prevents the buckle body from easily opening by self-rotation.

[0044] In one embodiment, such as Figures 9 to 13 As shown, a gap is formed between the fixing tooth 101 and the inner surface of the buckle body 200. The width of the gap (i.e., the opening size) is smaller than the thickness of the belt. This ensures that the fixing tooth 101 can effectively press and fix the belt, while also facilitating the buckle body 200 to rotate and open under the action of external force.

[0045] In one embodiment, such as Figures 9 to 13 As shown, the inner surface of the buckle 200 has a groove 203 at the position corresponding to each fixing tooth 101. When the fixing tooth 101 presses the belt, uneven anti-slip surfaces are generated on both sides of the belt, further preventing the belt from accidentally coming loose.

[0046] Example 4 like Figures 14 to 16As shown in the figure, the tail clip for a belt buckle in this embodiment includes a fixed base 1 and a locking member 2 movably connected to the fixed base 1 at one end. One end of the fixed base 1 is provided with a through groove 10 for the belt to pass through and exit. The locking member 2 is rotatably and slidably mounted on the fixed base 1 and allows the belt that passes through the through groove 10 to pass through in the opposite direction. That is, the belt that passes through the through groove 10 can pass through the locking member 2 in the opposite direction, and then the belt exits from the through groove 10. In other words, the belt enters and exits in the through groove and passes through the locking member, thereby fixing the beginning of the belt. The length of the belt can be adjusted by adjusting the length of the belt that exits from the through groove. This allows the length of the belt to be easily adjusted at the beginning of the belt, so that the length of the belt does not need to be cut to fit different body shapes. When manufacturers and retailers prepare belts, they only need to prepare belts of one length and size, thereby solving various problems existing in the prior art when it is necessary to prepare belts of different lengths.

[0047] Specifically, such as Figures 14 to 16 As shown, the locking element 2 is located on the inner side of the fixing seat so that the first end of the belt that passes through it is located on the inner side of the belt close to the body when in use. This allows the outer belt to cover it, preventing it from being exposed and affecting the aesthetics when in use. The outer belt part and the body can also be used to clamp the inner belt part together, preventing it from falling off or sticking up during use.

[0048] like Figures 14 to 16 As shown, in order to better and more conveniently lock and loosen the belt, after the locking member 2 rotates and / or slides (i.e., moves) relative to the fixed seat 1, the free end of the locking member 2 (i.e., the end away from the rotatable connection with the fixed seat) approaches or moves away from the through groove 10 to clamp or loosen the belt passing through the through groove 10. That is, when the free end of the locking member 2 rotates toward the inner side of the fixed seat, it gradually approaches the position of the through groove 10, and finally the locking member 2 is located inside the through groove 10, thereby forming a gap between the locking member 2 and the through groove 10 to clamp the belt. At this time, when the belt is pulled outward, the locking member 2 moves outward under the action of the pulling force. As it moves, it gets closer and closer to the through groove, gradually reducing the gap between the locking element and the through groove and further tightening the belt. This achieves a tightening effect as it is pulled, ensuring that there will be no loosening during use. When it is necessary to loosen or adjust the length of the belt, simply push the belt into the through groove. Under the force of the push, the locking element moves away from the through groove and rotates outward (i.e., rotates away from the fixed seat). At this time, the locking element and the through groove move away from each other, making it easy to loosen the belt and adjust its length. There is no need for complicated repeated pulling and pulling of the belt. The entire locking and loosening adjustment process is simple and convenient.

[0049] In one embodiment, such as Figures 14 to 16As shown, the fixed base 1 includes a base 11 and a limiting rod 111 integrally formed on one side of the base. A through groove 10 is formed between the limiting rod 111 and the fixed base 1.

[0050] In one embodiment, such as Figures 14 to 16 As shown, a hollow groove 12 is provided on the base 11 at a position corresponding to the limiting rod 111. The hollow groove 12 serves two purposes: first, it creates a clearance notch at the through groove 10, which effectively expands the width of the through groove, making it easier for the belt to be inserted and removed from the through groove. This avoids the belt being difficult to insert when the width of the through groove is similar to the thickness of the belt. Second, it also reduces the sliding friction between the belt and the fixing seat, making it easier for the user to push the belt inward to loosen it.

[0051] Specifically, such as Figures 14 to 16 As shown, due to the hollowed-out groove, the front end of the base 11 protrudes out of the through groove 10. One end of the protruding through groove 10 is misaligned with the limiting rod 111 to form a pressure rod 13. The pressure rod 13 can flatten the outer waist belt part, thus flattening the waist belt.

[0052] In a practical application, the width of the hollow groove 12 can be made greater than the width of the limiting rod 111, so that the waist belt has a larger range of motion when passing through the through groove.

[0053] In one embodiment, such as Figures 14 to 16 As shown, one end of the locking member 2 is rotatably and slidably mounted on the base 11 via the rotating shaft 3.

[0054] like Figures 14 to 16 As shown, the base 11 is provided with a through hole 15 for the rotating shaft 3 to pass through. The diameter of the through hole 15 is equal to or slightly larger than the outer diameter of the rotating shaft 3, and both ends of the rotating shaft 3 protrude from the through hole 15. The locking member 2 is a U-shaped rod. The two arm ends of the locking member 2 are respectively placed on both sides of the fixed base 1. Both arm ends of the locking member 2 are provided with waist-shaped holes 14. Both ends of the rotating shaft 3 are rotatably and slidably inserted into the waist-shaped holes 14 at the two arm ends. That is, the width and length of the waist-shaped holes 14 are both greater than the outer diameter of the rotating shaft 3. The locking member 2 utilizes a U-shaped structure to form a through hole 20 between the locking member 2 and the base 11.

[0055] Specifically, the length of the waist-shaped hole 14 extends back and forth along the arm end of the locking member 2.

[0056] In other embodiments, the maximum width of the fixing seat is the same as the maximum width of the locking member, and the length of the through groove is the same as the length of the through hole. That is, the fixing seat has recessed clearance positions on both sides at the end away from the through groove to accommodate the end of the locking member arm.

[0057] Example 5 like Figures 14 to 19As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 4.

[0058] Specifically, such as Figures 17 to 19 As shown, the belt buckle also includes a U-shaped buckle body 200, which has a U-shaped groove 206 with one end open for the belt to be inserted. The end of the fixing seat 1 furthest from the through groove 10 is rotatably positioned inside the open end of the U-shaped groove 206 via a rotating shaft 3. Specifically, both ends of the rotating shaft protrude from the two arm ends of the locking member 2 and are inserted into the open end of the buckle body 200. A U-shaped rod 207 is integrally formed on the outer side of the open end of the buckle body 200, connecting the two sides of the open end, to... A limiting groove 208 is formed between the U-shaped rod 207 and the tail clip 100 for the waist belt to pass through; a needle rod 300 is rotatably provided in the middle of the rotating shaft 3. The movable end of the needle rod 300 overlaps the outer side of the end away from the opening in the U-shaped groove 206. That is, when in use, the tail end of the waist belt passes through the U-shaped groove 206 from the inside to the outside, and then is inserted into the fixing hole on the waist belt through the needle rod 300. Then the tail end of the waist belt passes through the limiting groove 208, so that the tail end of the waist belt is located outside the tail clip 100.

[0059] It is understandable that, in order to allow one end of the needle bar 300 to be rotatably located in the middle of the movable rod 201, a notch for accommodating the end of the needle bar 300 is provided in the middle of the end of the fixed seat away from the through groove 10.

[0060] Example 6 like Figures 20 to 22 As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 4.

[0061] Specifically, such as Figures 20 to 22 As shown, the belt buckle also includes a buckle body 200. One end of the fixing seat 1, away from the through groove 10, is rotatably disposed in the middle of the inner side of the buckle body 200 via a rotating shaft 3. The two ends of the rotating shaft protrude from the two arm ends of the locking member 2 and are inserted into the buckle body 200, so that the tail clip 100 is located inside one end of the buckle body 200. A limiting member 400 is provided on the outer side of the other end of the buckle body 200. A limiting hole 401 for the belt to pass through is provided through the limiting member 400. One end of the limiting member 400 is rotatably disposed on the rotating shaft. The boom 402 and the buckle body 200 have an insertion groove 209 located inside the limiting member 400 through one end. The width of the insertion groove is greater than the coverage area of ​​the limiting member 400, so that a gap 403 is formed between the end of the limiting member 400 away from the rotating arm and the end of the insertion groove away from the rotating shaft 3 for the belt to pass through. That is, when in use, the tail end of the belt passes through the insertion groove 209 and the limiting hole 401 from the inside to the outside, and then the tail end of the belt passes through the limiting member and is inserted into the gap from the outside to the inside.

[0062] In one embodiment, when the number of rotating arms is two spaced apart, in order to connect the rotating arm 402 to the rotating shaft, a gap is formed between the two arm ends of the locking member and the rotating seat to accommodate the rotating arm 402.

[0063] In one embodiment, when there is only one rotating arm and it is located at the middle of one end of the limiting member, in order to connect the rotating arm 402 to the rotating shaft, a notch for accommodating the rotating arm 402 is provided at the middle of one end of the fixed seat away from the through groove 10.

[0064] Example 7 like Figures 27 to 29 As shown in the figure, the tail clip for a belt buckle in this embodiment includes a fixed base 1 and a locking member 2 movably connected to the fixed base 1 at one end. One end of the fixed base 1 is provided with a through groove 10 for the belt to pass through and exit. The locking member 2 is rotatably and slidably mounted on the fixed base 1 and allows the belt that passes through the through groove 10 to pass through in the opposite direction. That is, the belt that passes through the through groove 10 can pass through the locking member 2 in the opposite direction, and then the belt exits from the through groove 10. In other words, the belt enters and exits in the through groove and passes through the locking member, thereby fixing the beginning of the belt. The length of the belt can be adjusted by adjusting the length of the belt that exits from the through groove. This allows the length of the belt to be easily adjusted at the beginning of the belt, so that the length of the belt does not need to be cut to fit different body shapes. When manufacturers and retailers prepare belts, they only need to prepare belts of one length and size, thereby solving various problems existing in the prior art when it is necessary to prepare belts of different lengths.

[0065] Specifically, such as Figures 27 to 29 As shown, the locking element 2 is located on the inner side of the fixing seat so that the first end of the belt that passes through it is located on the inner side of the belt close to the body when in use. This allows the outer belt to cover it, preventing it from being exposed and affecting the aesthetics when in use. The outer belt part and the body can also be used to clamp the inner belt part together, preventing it from falling off or sticking up during use.

[0066] like Figures 27 to 29As shown, in order to better and more conveniently lock and loosen the belt, after the locking member 2 rotates and / or slides (i.e., moves) relative to the fixed seat 1, the free end of the locking member 2 (i.e., the end away from the rotatable connection with the fixed seat) approaches or moves away from the through groove 10 to clamp or loosen the belt passing through the through groove 10. That is, when the free end of the locking member 2 rotates toward the inner side of the fixed seat, it gradually approaches the position of the through groove 10, and finally the locking member 2 is located inside the through groove 10, thereby forming a gap between the locking member 2 and the through groove 10 to clamp the belt. At this time, when the belt is pulled outward, the locking member 2 moves outward under the action of the pulling force. As it moves, it gets closer and closer to the through groove, gradually reducing the gap between the locking element and the through groove and further tightening the belt. This achieves a tightening effect as it is pulled, ensuring that there will be no loosening during use. When it is necessary to loosen or adjust the length of the belt, simply push the belt into the through groove. Under the force of the push, the locking element moves away from the through groove and rotates outward (i.e., rotates away from the fixed seat). At this time, the locking element and the through groove move away from each other, making it easy to loosen the belt and adjust its length. There is no need for complicated repeated pulling and pulling of the belt. The entire locking and loosening adjustment process is simple and convenient.

[0067] In one embodiment, such as Figures 27 to 29 As shown, the fixed base 1 includes a base 11 and a limiting rod 111 integrally formed on one side of the base. A through groove 10 is formed between the limiting rod 111 and the fixed base 1.

[0068] In one embodiment, such as Figures 27 to 29 As shown, a hollow groove 12 is provided on the base 11 at a position corresponding to the limiting rod 111. The hollow groove 12 serves two purposes: first, it creates a clearance notch at the through groove 10, which effectively expands the width of the through groove, making it easier for the belt to be inserted and removed from the through groove. This avoids the belt being difficult to insert when the width of the through groove is similar to the thickness of the belt. Second, it also reduces the sliding friction between the belt and the fixing seat, making it easier for the user to push the belt inward to loosen it.

[0069] Specifically, such as Figures 27 to 29 As shown, due to the hollowed-out groove, the front end of the base 11 protrudes out of the through groove 10. One end of the protruding through groove 10 is misaligned with the limiting rod 111 to form a pressure rod 13. The pressure rod 13 can flatten the outer waist belt part, thus flattening the waist belt.

[0070] In a practical application, the width of the hollow groove 12 can be made greater than the width of the limiting rod 111, so that the waist belt has a larger range of motion when passing through the through groove.

[0071] In one embodiment, such as Figures 27 to 29 As shown, one end of the locking member 2 is rotatably and slidably mounted on the base 11 via the rotating shaft 3.

[0072] In one embodiment, such as Figures 27 to 29 As shown, one end of the locking member 2 is rotated via the rotating shaft 3 and slidably mounted on the fixed base 1.

[0073] Specifically, such as Figures 27 to 29 As shown, a connecting part 16 protrudes from both sides of the end of the fixed base away from the through groove 10; a through hole 20 for the belt to pass through is provided through the locking member 2; at least one pivot lug 21 is provided at one end of the locking member 2 located between the two connecting parts 16; the rotating shaft 3 passes through the connecting part 16 and the pivot lug 21; the pivot lug 21 is provided with a waist-shaped hole 14 for the rotating shaft 3 to pass through, so that the rotating shaft 3 can rotate and slide through the locking member 2, that is, the width and length of the waist-shaped hole 14 are both greater than the outer diameter of the rotating shaft 3.

[0074] It is understandable that the length of the waist-shaped hole 14 extends back and forth along the length of the pivot lug 21.

[0075] Of course, in another practical case, the waist-shaped hole can be set on the connecting part, and the length direction of the waist-shaped hole extends along the front and back of the fixed seat so that the rotating shaft can rotate and slide through the fixed seat. However, when the fixed seat is connected to the buckle body of the belt buckle, the rotating shaft is not connected to the buckle body. The connection method between the tail clip and the buckle body refers to the connection structure shown in Embodiments 2 and 3.

[0076] Example 8 like Figures 27 to 31 As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 7.

[0077] Specifically, such as Figures 30 to 31 As shown, the belt buckle also includes a buckle body 200 with an automatic buckle 210 at one end. The end of the fixing seat 1 away from the through groove 10 is rotatably mounted on the other end of the buckle body 200 via the rotating shaft 3. That is, the fixing seat 1 is rotatably connected to the end of the buckle body 200 away from the automatic buckle. Both ends of the buckle body 200 form gaps between the automatic buckle and the tail clip for the belt to pass through. That is, the tail end of the belt is inserted through the gap between the buckle body and the automatic buckle, and finally passes through the gap between the buckle body and the tail clip. During this process, the locking tongue on the automatic buckle 210 cooperates with the slot on the belt to lock the belt.

[0078] In one embodiment, the automatic buckle 210 is a conventional spring-loaded latch structure, and its method of securing the belt is a conventional technical means, which will not be described in detail here.

[0079] Example 9 like Figures 32 to 34As shown in the figure, the tail clip for a belt buckle in this embodiment is basically similar in structure to that shown in embodiment 7, except that the structure of the fixing base is different and the positions of the connecting part and the pivot ear are different, as detailed below: like Figures 32 to 34 As shown, the end of the fixed seat 1 away from the through groove 10 is integrally formed with a connecting plate 17 through the connecting part 16. Both sides of the connecting part 16 have concave positions relative to the connecting plate 17 and the fixed seat 1. The locking member 2 is provided with a through hole 20 for the belt to pass through. One end of the locking member 2 is provided with two pivot ears 21 located on both sides of the connecting part 16 respectively. That is, the pivot ears 21 are located in the concave positions. The rotating shaft 3 passes through the pivot ears 21 and the connecting part 16. The pivot ears 21 are provided with a waist-shaped hole 14 for the rotating shaft 3 to pass through, so that the rotating shaft 3 can rotate and slide through the locking member 2. That is, the width and length of the waist-shaped hole 14 are both greater than the outer diameter of the rotating shaft 3.

[0080] Specifically, the length of the waist-shaped hole 14 extends back and forth along the length of the pivot lug 21.

[0081] Of course, in another practical case, the waist-shaped hole can be set on the connecting part, and the length direction of the waist-shaped hole extends along the front and back of the fixed seat so that the rotating shaft can rotate and slide through the fixed seat. However, when the fixed seat is connected to the buckle body of the belt buckle, the rotating shaft is not connected to the buckle body. The connection method between the tail clip and the buckle body refers to the connection structure shown in Embodiments 2 and 3.

[0082] Example 10 like Figures 32 to 38 As shown in the figure, a belt buckle in this embodiment includes a tail clip 100 as described in embodiment 7.

[0083] Specifically, such as Figures 35 to 38As shown, the belt buckle also includes a buckle body 200, with a first end and a second end at its two ends. The end of the connecting plate 17 furthest from the fixing seat is fixed to the inner side of the first end of the buckle body 200 via an elastic telescopic member 500. The rotating shaft 3 is inserted and fixed to the inner side of the second end of the buckle body 200. A cover plate 600 is rotatably mounted on the outer side of the buckle body 200, with one end of the cover plate 600 rotatably positioned outside the first end of the buckle body 200. A fixing groove 202 is formed between the cover plate 600 and the connecting plate 17 for the end of the belt to pass through. The rotating end of the cover plate 600 is provided with several... The fixing teeth 101, which are perpendicular to the insertion direction of the fixing groove 202, allow the cover plate 600 to be opened by first rotating it outwards during use, so that the end of the belt can be inserted into the fixing groove 202. After the end of the belt is inserted into the fixing groove 202, the cover plate 600 is closed by rotating it. The fixing teeth 101 exert a strong clamping force on the end of the belt inserted into the fixing groove 202, thereby fixing the end of the belt and preventing the belt from coming loose due to insufficient clamping force. In addition, the interaction force between the belt and the fixing teeth can also prevent the buckle from easily opening by self-rotation.

[0084] In one embodiment, a gap is formed between the fixing tooth 101 and the inner surface of the connecting plate 17. The width of the gap (i.e., the opening size) is smaller than the thickness of the belt. This ensures that the fixing tooth 101 can effectively press and fix the belt, while also facilitating the rotation, closing and opening of the buckle 200 under the action of external force.

[0085] In one embodiment, such as Figures 35 to 38 As shown, the inner surface of the connecting plate 17 is provided with a groove 203 at the position corresponding to each fixing tooth 101. When the fixing tooth 101 presses the belt, uneven anti-slip surfaces will be generated on both sides of the belt, further preventing the belt from accidentally coming loose.

Specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the embodiments above are only for helping to understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
