Description

Belt buckle and belt assembly Technical Field

[0001] The present invention relates to the field of clothing accessories, and more specifically, to a belt buckle and a belt assembly. Background Art

[0002] Belt buckles are essential components of belts, used to adjust the tightness and lock the belt. Existing belt buckles can be categorized as either inside-worn or outside-worn. When the fixed end and tail end of the belt overlap in the direction of wear, a buckle with the fixed end on the outside and the tail end on the inside is considered an inside-worn style, while an outside-worn style is considered an outside-worn style. The inside refers to the side closest to the abdomen. Inside-worn belt buckles prevent the tail end of the belt from lifting outward or falling out of the trouser loop, affecting the neatness of the wearer. Their market share has been steadily increasing in recent years.

[0003] In the related art, a locking structure is used to lock the inner-threading belt buckle of the belt, usually as shown in Figures 5 and 6. The fixed end of the belt is located on the outside, and the tail end of the belt is also located on the outside when it is initially threaded. When the tail end of the belt is threaded close to the fixed end of the belt, the tail end is easily blocked by the fixed end and cannot move forward. Therefore, a guide member is required to guide the tail end of the belt to avoid the obstruction of the fixed end and move to the inside, thereby realizing the inner threading of the belt. This method has the following problems due to the provision of a guide member: ① The gap between the tail end and the fixed end of the belt is large, the layers are not clear, and the wearing smoothness and appearance are reduced; ② The friction between the tail end of the belt and the guide member causes a large amount of belt wear. Technical issues

[0004] The purpose of the embodiments of the present application is to provide a belt buckle and belt assembly to solve the technical problems of the existing inner-wearing belt buckle that locks the belt through a locking structure, the large gap between the tail end and the fixed end of the belt and the unclear layers due to the provision of a guide, which reduces the smoothness and visual effect of wearing, as well as the large degree of bending and wear of the belt.

Modes for Carrying Out the Invention

[0063] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0064] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0065] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0066] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0067] 1A, 1B, 2A, 3A, 3B, and 4A, the belt buckle provided in this application will now be described. The belt buckle includes a base 1, a baffle 2, side wings 3, and a locking member 4. The base 1 has a first end 11 and a second end 12 that are opposite to each other in a first direction X. Specifically, the first direction X is the direction in which the belt is threaded. The first end 11 is used to fix the fixed end 81 of the belt.

[0068] The baffle 2 and the second end 12 of the base 1 are spaced apart in the second direction Y, and the second direction Y is the thickness direction of the belt; the side wing 3 is connected between the second end 12 of the base 1 and the baffle 2, and the side wing 3, the second end 12 of the base 1 and the baffle 2 form a passage cavity for the tail end 82 of the belt to pass through; the locking member 4 is movably provided on the side wing 3 or the base 1, and is located on the side of the baffle 2 close to the base 1, and is used to lock or release the tail end 82 of the belt between the baffle 2 and the locking member 4.

[0069] It should be noted here that the "locking member 4 locks the tail end 82 of the belt between the baffle 2 and the locking member 4" involved in this application means that the locking member 4 can limit the displacement of the tail end 82 of the belt in the direction of the belt's insertion, so that the tail end 82 of the belt can be fixed in the first direction X; the displacement of the tail end 82 of the belt in other directions can be restricted or not, that is, the tail end 82 of the belt can be fixed in other directions or not, as long as the tail end 82 of the belt can be fixed in the first direction X, no specific limitation is made here.

[0070] Specifically, the belt has a fixed end 81 and a tail end 82. The fixed end 81 of the belt is fixed to the first end 11 of the base 1. When the belt needs to be tightened, the tail end 82 of the belt is passed through the passage cavity between the side wing 3, the second end 12 of the base 1 and the baffle 2. When the belt is in place, the tail end 82 of the belt is locked between the baffle 2 and the locking member 4 by movably providing the locking member 4 on the side wing 3 or the base; when the belt needs to be loosened, the tail end 82 of the belt is loosened between the baffle 2 and the locking member 4 by movably providing the locking member 4 on the side wing 3 or the base, so that the tail end 82 of the belt can move freely.

[0071] The belt buckle provided in this embodiment is compared with the prior art. The first end 11 of the base 1 is used to fix the fixed end 81 of the belt, the baffle 2 and the second end 12 of the base 1 are spaced apart in the second direction Y, the side wing 3 is connected between the second end 12 of the base 1 and the baffle 2, and the tail end 82 of the belt can be passed through the passage cavity surrounded by the side wing 3, the second end 12 of the base 1 and the baffle 2, and locked or released between the baffle 2 and the locking member 4. At this time, the fixed end 81 of the belt is located on the outside, and the tail end 82 of the belt is located on the inside when it is initially passed through, so that the tail end 82 of the belt is directly placed on the inside and passes through the belt buckle in the forward direction. The fixed end 81 of the belt will not block the passing of the tail end 82 of the belt, so there is no need to set a guide for the tail end 82 of the belt. forward guide 10; based on this, on the one hand, the fixed end 81 and the tail end 82 of the belt can be clearly layered, the gap between the fixed end 81 and the tail end 82 of the belt can be reduced, and the wearing smoothness and visual experience can be improved; on the other hand, since there is no need to set the guide 10, the bending of the tail end 82 of the belt can be greatly reduced, and the problem of large wear caused by setting the guide 10 can be avoided; on the third hand, the threading cavity is surrounded by the side wing 3, the second end 12 of the base 1 and the baffle 2, and the tail end 82 of the belt is locked or released between the baffle 2 and the locking member 4. Since the locking member 4 is located on the side of the baffle 2 close to the base 1, the space can be fully utilized, the structure of the belt buckle is streamlined, and the comfort of the human body is increased.

[0072] In the prior art, as shown in FIG7 , the baffle 2 and the base 1 are spaced apart in the second direction Y, and the locking member 4 is provided on the side of the baffle 2 facing away from the base 1. This structure cannot make full use of the space, increases the thickness of the belt buckle in the second direction Y, and the locking member 4 is located on the side close to the human body and contacts the human body, which reduces the comfort of the human body.

[0073] In the present application, the locking member 4 is movably provided on the side wing 3 or the base 1, and is located on the side of the baffle 2 close to the base 1. In this way, not only can the space be fully utilized and the thickness of the belt buckle in the second direction Y be reduced, thereby streamlining the structure of the belt buckle, but also the locking member 4 can be prevented from directly contacting the human body, allowing the baffle 2 to be located on the side close to the human body and in contact with the human body, which will increase the comfort of the human body.

[0074] In actual applications, there are many ways in which the locking member 4 can be movably arranged on the side wing 3 or the base 1. For example, the locking member 4 can be moved relative to the side wing 3 or the base 1, or the locking member 4 can be rotated relative to the side wing 3 or the base 1. This embodiment does not make specific limitations on this.

[0075] In one embodiment, as shown in Figures 1A to 2E, a slide groove 31 is provided on the side wing 3, which runs through the third direction Z. The distance between the slide groove 31 and the baffle 2 gradually changes from the side close to the first end 11 to the side away from the first end 11. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. The locking member 4 is a roller 41, which is slidably arranged in the slide groove 31 and is used to lock or release the tail end 82 of the belt between the baffle 2 and the roller 41.

[0076] Since the distance between the slide groove 31 and the baffle 2 gradually changes from the side close to the first end 11 to the side away from the first end 11, the roller 41 is slid in the slide groove 31, so that the distance between the roller 41 in the slide groove 31 and the baffle 2 in the second direction Y is reduced, so that the belt is locked between the baffle 2 and the roller 41; when the belt needs to be loosened, the roller 41 is slid in the opposite direction in the slide groove 31, so that the distance between the roller 41 in the slide groove 31 and the baffle 2 in the second direction Y becomes larger, so that the belt is loosened between the baffle 2 and the roller 41, allowing the tail end 82 of the belt to move freely.

[0077] If the distance between the slide groove 31 and the baffle 2 gradually increases from the side close to the first end 11 to the side away from the first end 11, when the belt needs to be tightened, the tail end 82 of the belt is passed through the passage cavity between the side wing 3, the second end 12 of the base 1 and the baffle 2. When the belt is in place, the roller 41 is slid in the slide groove 31 toward the first end 11 of the base 1 until the roller 41 presses the belt until the belt is locked between the baffle 2 and the roller 41. At this time, the human abdomen will have an outward tension acting on the belt, causing the tail end 82 of the belt to retreat, driving the roller 41 to move in the direction away from the first end 11, and the distance between the roller 41 and the baffle 2 increases, so that the belt is loosened between the baffle 2 and the roller 41, and the belt cannot be locked.

[0078] If the distance between the chute 31 and the baffle 2 gradually decreases from the side close to the first end 11 to the side away from the first end 11, when the roller 41 presses the belt until the belt is locked between the baffle 2 and the roller 41, an outward-expanding tension will act on the belt from the abdomen of the human body, causing the tail end 82 of the belt to retreat, driving the roller 41 to move away from the first end 11, and the distance between the roller 41 and the baffle 2 to decrease, causing the belt to be locked between the baffle 2 and the roller 41, thus achieving automatic locking of the belt. When it is necessary to loosen the belt, the roller 41 can be moved toward the first end 11 to increase the distance between the roller 41 and the baffle 2, causing the belt to loosen between the baffle 2 and the roller 41, and then the tail end 82 of the belt can be withdrawn from the threading cavity; or the tail end 82 of the belt can be pulled forward, causing the tail end 82 of the belt to drive the roller 41 toward the first end 11, and then the tail end 82 of the belt can be withdrawn from the threading cavity. Therefore, preferably, as shown in Figures 1B and 1D, the distance between the slide groove 31 and the baffle 2 gradually decreases from the side close to the first end 11 to the side away from the first end 11, that is, the distance between the side of the slide groove 31 close to the first end 11 of the base 1 and the baffle 2 is the largest, and the distance between the side of the slide groove 31 away from the first end 11 of the base 1 and the baffle 2 is the smallest. In this way, not only can the automatic locking of the belt be achieved, but the loosening of the belt can also be facilitated.

[0079] It should be noted here that the distance between the slide groove 31 and the baffle 2 refers to the distance between the groove wall of the slide groove 31 on the side close to the baffle 2 and the baffle 2 in the direction perpendicular to the baffle 2. In this embodiment, from the side close to the first end 11 to the side away from the first end 11, the distance between the groove wall of the slide groove 31 on the side close to the baffle 2 and the baffle 2 in the direction perpendicular to the baffle 2 gradually decreases.

[0080] In actual application, the distance between the side of the slide 31 close to the first end 11 of the base 1 and the baffle 2 is greater than the thickness of the belt, and the distance between the side of the slide 31 away from the first end 11 of the base 1 and the baffle 2 is less than or equal to the thickness of the belt. In this way, when the roller 41 slides in the slide 31, the belt can be locked or released between the baffle 2 and the roller 41.

[0081] In practical applications, the shape of the slide groove 31 is not specifically limited. For example, the slide groove 31 can be an arc groove or a linear groove, as long as the roller 41 can lock or release the belt between the baffle 2 and the roller 41 when sliding in the slide groove 31.

[0082] In one embodiment, as shown in Figures 3A to 4F, the locking member 4 includes a rotating shaft 42 and a locking tongue 43. The rotating shaft 42 is mounted on the base 1 or the side wing 3 so as to rotate around a straight line parallel to the third direction Z. The locking tongue 43 is fixed to the rotating shaft 42 and is located in the penetration cavity, and is used to lock or release the tail end 82 of the belt between the baffle 2 and the locking tongue 43. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0083] Since the rotating shaft 42 is mounted on the base 1 or the side wing 3 so as to rotate around a straight line parallel to the third direction Z, the locking tongue 43 is fixed to the rotating shaft 42 and is located in the through-cavity. When the rotating shaft 42 is rotated to rotate the locking tongue 43 toward the baffle 2, the distance between the locking tongue 43 and the baffle 2 in the second direction Y is reduced, so that the belt is locked between the baffle 2 and the locking tongue 43; when the rotating shaft 42 is rotated to rotate the locking tongue 43 in a direction away from the baffle 2, the distance between the locking tongue 43 and the baffle 2 in the second direction Y is increased, so that the belt is loosened between the baffle 2 and the locking tongue 43, allowing the tail end 82 of the belt to move freely.

[0084] In practice, during the rotation of shaft 42, locking tongue 43 has two extreme states. In the first extreme state, the distance between locking tongue 43 and baffle 2 in the second direction Y is minimum, and this distance is less than or equal to the thickness of the belt. In the second extreme state, the distance between locking tongue 43 and baffle 2 in the second direction Y is maximum, and this distance is greater than the thickness of the belt. In this way, when rotating shaft 42 rotates, the belt can be locked or released between baffle 2 and locking tongue 43.

[0085] In one embodiment, as shown in Figures 3A and 4A, the locking member 4 further includes a reset structure 44, one end of the reset structure 44 is connected to the base 1 or the side wing 3, and the other end of the reset structure 44 is connected to the rotating shaft 42 or the lock tongue 43. The reset structure 44 is used to drive the lock tongue 43 to automatically reset to the locked state.

[0086] Specifically, in the initial state, the locking tongue 43 is in a locked state. When the belt needs to be tightened, the rotating shaft 42 is rotated to rotate the locking tongue 43 in the direction away from the baffle 2, so that the distance between the locking tongue 43 and the baffle 2 in the second direction Y increases. At this time, the belt can pass between the locking tongue 43 and the baffle 2. At this time, the reset structure 44 accumulates force; when the belt is in place, the rotating shaft 42 is stopped, and under the action of the restoring force of the reset structure 44, the locking tongue 43 is driven to rotate toward the baffle 2, so that the locking tongue 43 is automatically reset to the locked state, so that the belt is locked between the locking tongue 43 and the baffle 2.

[0087] In practical applications, the reset structure 44 can be a magnetic member or an elastic member, as long as it can drive the lock tongue 43 to automatically reset to the locked state. Those skilled in the art can choose the setting according to actual needs.

[0088] When the reset structure 44 is an elastic member, a tensile type, a compression type, a bending type, a torsion type, etc. can be selected according to the type of the elastic member, for example, a bending type or a torsion type spring sheet. The elastic member can act on the lock tongue 43 directly or indirectly. Direct connection methods include but are not limited to connection with the lock tongue 43 by means of set installation, press installation, welding installation, threaded connection installation, clamping connection, adhesive connection, etc. Indirect connection methods generally require the provision of a centering member, such as a support member connection, a lever member connection, a hook connection, etc., or the elastic member can achieve indirect action by connecting to the rotating shaft 42. For example, as shown in Figures 3A and 4A, the belt buckle head also includes a cover plate 6 covering the base 1, one end of the elastic member is connected to the rotating shaft 42, and the other end abuts against the cover plate 6. In this way, the belt buckle head as a whole can be made more compact and simple, simplifying the use process of the belt buckle head and simplifying the production and assembly process.

[0089] When the reset member is a magnetic member, it acts on the locking member 4 through magnetic force, so the magnetic member and the locking member 4 can be non-contact, wherein the magnetic source of the locking member 4 can be its own material, or it can be other magnetic members installed on the positioning member. Similarly, the connection methods of the magnetic member include magnetic suction installation, adhesive installation, threaded installation, snap ring bayonet installation, elastic clamping installation, support member connection, lever member connection, etc. There are also many ways to combine the position and quantity of the elastic member or magnetic member, such as using a single elastic member to be set on one side or in the middle of the rotating shaft 42, or using two elastic members to be symmetrically set on both sides or in the middle of the rotating shaft 42, etc. The reset structure 44 can make the belt buckle more convenient to use, but the reset structure 44 is not necessary for the operation of the belt buckle. In the absence of this reset structure 44, the belt buckle can also be reset to the locked state by manually turning the locking member 4.

[0090] In one embodiment, as shown in Figures 3A and 4A, the belt buckle also includes a limiting portion 46, which is provided on the locking member 4 or the base 1 or the side wing 3 or the baffle 2. The limiting portion 46 is used to limit the rotation of the rotating shaft 42 so that the locking tongue 43 is always facing the forward direction of the tail end 82 of the belt.

[0091] The following is an example in which the first direction X is the left-right direction, wherein the first end 11 of the base 1 is on the left and the second end 12 of the base 1 is on the right. The forward direction of the tail end 82 of the belt is from the second end 12 to the first end 11.

[0092] Due to the action of the reset structure 44, in the initial state, the locking tongue 43 is in a locked state. When the tail end 82 of the belt moves forward and contacts the locking tongue 43, since the locking tongue 43 is always facing the forward direction of the tail end 82 of the belt, that is, the locking tongue 43 is always located on the left side of the rotating shaft 42, the direction of the locking tongue 43 is consistent with the forward direction of the tail end 82 of the belt. The tail end 82 of the belt can push the locking tongue 43 to overcome the action of the reset structure 44, and the distance between the locking tongue 43 and the baffle 2 in the second direction Y increases, so that the tail end 82 of the belt can move forward smoothly. On the contrary, if the limiting portion 46 is not provided to limit the rotation of the rotating shaft 42, so that the locking tongue 43 can be rotated to the right side of the rotating shaft 42, the direction of the locking tongue 43 is inconsistent with the forward direction of the tail end 82 of the belt. When the tail end 82 of the belt moves forward, the locking tongue 43 will be pushed to overcome the action of the reset structure 44. At this time, the distance between the locking tongue 43 and the baffle 2 in the second direction Y is reduced, thereby blocking the forward movement of the tail end 82 of the belt, and it is easy for the tail end 82 of the belt to be unable to move forward.

[0093] By setting the limiting portion 46 to limit the rotation of the rotating shaft 42, the locking tongue 43 is always oriented towards the forward direction of the tail end 82 of the belt, which can avoid the situation where the tail end 82 of the belt cannot move forward and allows the tail end 82 of the belt to move forward smoothly.

[0094] The specific position and specific shape of the limiting portion 46 are not specifically limited. For example, the limiting portion 46 can be provided on the locking member 4 (for example, as shown in Figures 3A and 4A, the limiting portion 46 is provided on the rotating shaft 42 of the locking member 4), or it can be provided on the base 1, or it can be provided on the side wing 3 or the baffle 2. The limiting portion 46 can be a raised structure as shown in Figures 3A and 4A, or it can be other structures. As long as it can limit the rotation of the rotating shaft 42 and allow the locking tongue 43 to always face the forward direction of the tail end 82 of the belt, technical personnel in this field can choose the setting according to actual needs.

[0095] In one embodiment, as shown in Figures 3A, 3C, 4A, and 4C, the locking member 4 further includes a switch control structure 45, which is connected to the rotating shaft 42 and is used to drive the rotating shaft 42 to rotate. By providing the switch control structure 45, it is convenient for the user to drive the rotating shaft 42 to rotate through the switch control structure 45, thereby driving the locking tongue 43 to lock or release the tail end 82 of the belt between the baffle 2 and the locking tongue 43.

[0096] In actual use, the switch control structure 45 can directly control the rotation of the rotating shaft 42, or it can indirectly control the rotation of the rotating shaft 42. The direct control method is usually a mechanical switch directly connected to the rotating shaft 42 that can be toggled, rotated, pulled, pushed, rotated, or pressed. The indirect control method generally works by providing a centering member, such as a latch-type structure or a button-type structure. Of course, the switch control structure 45 is not necessary for the operation of the belt buckle head, and the state of the locking structure can be changed by directly toggling the locking member 4, but the provision of the switch control structure 45 can improve the user experience.

[0097] 3A and 4A , the switch control structure 45 is an operating handle connected to the end of the rotating shaft 42 away from the through-hole. The operating handle is a conventional component that allows the belt buckle to be compact, stable, and reliable.

[0098] In order to make the locking effect of the belt more stable when worn, some structures that can increase the friction between the locking part 4 and the belt and / or increase the friction between the belt and the baffle 2 can be set. For example, in some embodiments, as shown in Figures 1A to 1F and Figures 3A to 3G, the end surface of the baffle 2 facing the base 1 is provided with an anti-slip pattern 21. The anti-slip pattern 21 can be a strip pattern, a grid pattern, etc., as long as it can increase the friction. This embodiment does not make specific restrictions on this. In this way, the friction between the baffle 2 and the belt can be increased, making the locking of the belt more stable when worn, and the production process is simple. For another example, in some other embodiments, as shown in Figures 2A to 2E and Figures 4A to 4F, the end surface of the baffle 2 facing the base 1 is provided with a protrusion 22, and the protrusion 22 is used to respectively cooperate with a plurality of grooves 83 on the end surface of the belt facing the baffle 2, wherein the plurality of grooves 83 are spaced apart along the first direction X. The number of protrusions 22 can be one or more, and the shape of the protrusion 22 can be a trapezoidal protrusion 22, a semi-cylindrical oblique protrusion 22, a semi-square column oblique protrusion 22, a semi-rectangular column oblique protrusion 22, etc.; in this way, the friction between the baffle 2 and the belt can be increased, making the locking of the belt more stable when worn. For another example, in some other embodiments, the surface of the locking member 4 is provided with an anti-slip structure, which can be a stripe pattern, a grid pattern, etc., as long as it can increase friction. This embodiment does not specifically limit this. In this way, the friction between the locking member 4 and the belt can be increased, making the locking of the belt more stable when worn, and the production process is simple.

[0099] When a protrusion 22 is provided on the end face of the baffle 2 facing the base 1, for an embodiment in which the locking member 4 is a roller 41, the distance between the side of the slide 31 close to the first end 11 of the base 1 and the protrusion 22 is greater than the thickness of the belt, and the distance between the side of the slide 31 away from the first end 11 of the base 1 and the protrusion 22 is less than or equal to the thickness of the belt; for an embodiment in which the locking member 4 includes a rotating shaft 42 and a locking tongue 43, in a first limit state, the distance between the locking tongue 43 and the protrusion 22 in the second direction Y is the smallest, and the distance is less than or equal to the thickness of the belt; in a second limit state, the distance between the locking tongue 43 and the protrusion 22 in the second direction Y is the largest, and the distance is greater than the thickness of the belt.

[0100] In practical applications, the base 1 and the side wing 3 as well as the side wing 3 and the baffle 2 can be connected by, but not limited to, gluing, welding, riveting, pressing, screwing, threading and clamping, so that the production process is more flexible.

[0101] The base 1 and the side wings 3 can also be integrally formed. In this way, the connection structure and connection process between the base 1 and the side wings 3 can be omitted, which can effectively ensure and improve the convenience, consistency, and stability of the connection between the base 1 and the side wings 3. The side wings 3 and the baffle 2 can also be integrally formed. In this way, the connection structure and connection process between the side wings 3 and the baffle 2 can be omitted, which can effectively ensure and improve the convenience, consistency, and stability of the connection between the side wings 3 and the baffle 2.

[0102] Preferably, in one embodiment, as shown in Figure 1B, the base 1, the baffle 2 and the side wing 3 are integrally formed, for example, they can be integrally cast. In this way, the connection structure and connection process between the base 1 and the side wing 3 and between the side wing 3 and the baffle 2 can be omitted, which can effectively ensure and improve the connection convenience, connection consistency and connection stability between the base 1 and the side wing 3 and between the side wing 3 and the baffle 2.

[0103] In one embodiment, as shown in Figures 1D to 1F, Figures 2C to 2E, Figures 3E to 3G and Figures 4D to 4F, the belt buckle further includes a limiting member 5 provided at the first end 11, the limiting member 5 and the side wing 3 are located on the same side of the base 1, and a through hole is provided on the limiting member 5 for the belt to pass through.

[0104] Specifically, the tail end 82 of the belt passes through the cavity between the side wing 3, the second end 12 of the base 1 and the baffle 2, and passes out from the through hole of the limiter 5. The limiter 5 can not only provide secondary fixation for the tail end 82 of the belt, but also provide guidance for the tail end 82 of the belt, so that the tail end 82 of the belt is not easy to get the wrong direction before entering the trouser loop. At the same time, it can also make the entire belt buckle more symmetrical and smooth.

[0105] In one embodiment, the belt buckle further includes a cover plate 6 covering the base 1, and the cover plate 6 is located on the side of the base 1 facing away from the baffle 2. The cover plate 6 on the base 1 can not only prevent dust from falling into the belt buckle, but also improve the appearance of the belt buckle.

[0106] The cover plate 6 can be installed on the base 1 by, but not limited to, gluing, welding, riveting, pressing, screw fastening, threaded connection and clamping. The cover plate 6 can also be integrally formed with the base 1, which is not specifically limited in this embodiment.

[0107] In practical applications, the fixed end 81 of the belt can be fixed to the first end 11 of the base 1 by, but not limited to, gluing, welding, riveting, crimping, screwing, threading, and clamping.

[0108] In one embodiment, as shown in Figures 1F, 2E, 3G, and 4F, the belt buckle further comprises a mounting plate 7 disposed on the base 1. The mounting plate 7 is spaced apart from the cover plate 6, and the fixed end 81 of the belt is located between the mounting plate 7 and the cover plate 6. The mounting plate 7 has a first fixing hole extending through its thickness (not shown), and the cover plate 6 has a second fixing hole (not shown) on the side facing the mounting plate 7. The belt buckle further comprises a fastener 9, which passes through the first fixing hole and the belt and is then fixed to the second fixing hole. In this way, the fastener 9 can be concealed by the cover plate 6, thereby improving the aesthetics of the belt buckle.

[0109] The mounting plate 7 can be installed on the base 1 by means of, but not limited to, gluing, welding, riveting, pressing, screw fastening, threaded connection and clamping. The mounting plate 7 can also be integrally formed with the base 1, which is not specifically limited in this embodiment.

[0110] Specifically, the fastener 9 can be a structure such as a screw, a pin, a rivet, a latch, a buckle, etc. The first fixing hole and the second fixing hole can both be threaded holes, and the fastener 9 can be a screw. After the fastener 9 is threadedly connected to the first fixing hole, it passes through the belt and is threadedly connected to the second fixing hole. Alternatively, one of the first fixing hole and the second fixing hole can be a threaded hole. For example, when the first fixing hole is a plain hole and the second fixing hole is a threaded hole, the fastener 9 can be a screw. After the fastener 9 passes through the first fixing hole, it passes through the belt and is threadedly connected to the second fixing hole. Alternatively, the first fixing hole and the second fixing hole can both be plain holes, and the fastener 9 can be a pin. After the fastener 9 passes through the first fixing hole and the belt, it is located in the second fixing hole. The fastener 9 has an interference fit with the first fixing hole and the second fixing hole.

[0111] In one embodiment, as shown in Figures 1C, 1F, 2B, 2E, 3G, and 4F, the stopper 5 and the fastener 9 are spaced apart in the first direction X. In this way, when the fixed end 81 of the belt is fixed by the fastener 9, the stopper 5 can avoid obstructing the installation of the fastener 9, which can facilitate the installation of the fastener 9.

[0112] The present application also provides a belt assembly, as shown in Figures 1E, 1F, 2D, 2E, 3G, and 4F. The belt assembly includes a belt and the aforementioned belt buckle. The fixed end 81 of the belt is fixed to the first end 11, and the tail end 82 of the belt can be locked or released between the baffle 2 and the locking member 4. The belt assembly provided in the embodiment of the present application has the belt buckle of any of the aforementioned embodiments, and therefore has all the beneficial effects of the aforementioned belt buckle, which will not be detailed here.

[0113] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
