Description

Technical Field

[0001] This utility model relates to the field of belt technology, and in particular to a belt buckle. Background Technology

[0002] The belt buckle is a key component of a belt, used to connect the two ends of the belt and to achieve both fixing and adjustment of tightness. Its core function is to ensure the belt remains stable when worn, while also allowing the user to quickly adjust the length as needed. Traditional belt buckles mainly use pin buckles or ratchet mechanisms; however, these structures have revealed many shortcomings in practical use:

[0003] (1) The pin buckle relies on the cooperation between the pin and the buckle hole to achieve fixation. The adjustment accuracy is low and it needs to be frequently inserted and removed. After long-term use, it is easy to loosen due to wear. Although the ratchet mechanism can achieve continuous adjustment, it requires pressing or flicking a specific part when releasing. The operation is cumbersome and may cause difficulty in unlocking or accidental loosening due to fatigue of the locking teeth.

[0004] (2) Some ratchet or multi-functional buckles need to integrate multiple springs, teeth and other parts, which not only increases the difficulty of assembly and manufacturing cost, but may also lead to overall failure due to wear of parts, reducing service life.

[0005] As users demand a higher level of user experience in wearable devices, developing a belt buckle that is easy to operate, structurally reliable, and ergonomic has become a key challenge in the industry. Currently, there is no solution that achieves quick fastening and release through a simple mechanical structure while also controlling costs. Utility Model Content

[0006] The purpose of this utility model is to provide a belt buckle to solve the problems existing in the prior art and improve the ease of operation and structural reliability of the belt buckle.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] This utility model provides a belt buckle, comprising:

[0009] Matrix;

[0010] A locking body, wherein a first end of the locking body is rotatably connected to one end of the base, and a channel for the belt to pass through is formed between the locking body and the base, and a second end of the locking body is far away from the first end, and a stop tooth for limiting the groove on the belt is fixed on the side of the second end of the locking body near the channel, and the end of the stop tooth away from the locking body is farther away from the first end of the locking body than the other end of the stop tooth.

[0011] A lever, the first end of which is rotatably connected to the second end of the locking body on the side away from the channel, a groove for preventing the rear end of the belt from being pushed off is formed between the lever and the locking body, and a plurality of locking pins for pressing the rear end of the belt are fixed on the side of the first end of the lever near the groove; the first end of the locking body can limit the middle part of the lever, and the contact point between the first end of the locking body and the lever serves as the fulcrum of the lever.

[0012] Preferably, the locking body is rotatably connected to the base body via a first connecting pin;

[0013] The first end of the lever is rotatably connected to the locking body via a second connecting pin.

[0014] Preferably, a limiting rod is provided at the other end of the base, the limiting rod being used to limit the waist belt within the channel along the thickness direction of the waist belt.

[0015] Preferably, the substrate is frame-shaped.

[0016] Preferably, the placement slot is located within the locking body.

[0017] Preferably, the lever is plate-shaped, the locking pin is conical, and the tip of the locking pin is far from the lever.

[0018] Preferably, the number of locking pins is 7, and all the locking pins are arranged sequentially along the width direction of the lever.

[0019] Preferably, the limiting rod is fixedly connected to the base.

[0020] Preferably, both ends of the limiting rod are rotatably connected to the base.

[0021] The present invention achieves the following technical advantages over the prior art:

[0022] This utility model's belt buckle, through its innovative design of a lever mechanism and a stop tooth, significantly improves the convenience, comfort, and mechanical performance of belt use. By turning the lever, the user can lift the stop tooth, thereby releasing it from the groove on the belt. Compared to traditional pin buckles that require repeated insertion and removal, and ratchet buckles that require pressing complex components, this utility model allows the user to lock and release the belt with just one hand, greatly simplifying the operation and saving significant time and effort. The stop tooth securely locks the belt in place, and because it is angled, it only prevents the belt from moving in the loosening direction; when tightening the belt, it does not prevent movement. The lever is relatively long, and by utilizing the mechanical lever principle, the force required to release the stop tooth is significantly reduced. Actual testing shows that compared to conventional belt buckles, it significantly reduces the force required to unlock, effectively preventing hand fatigue or belt damage caused by excessive force, while also enhancing the buckle's lifespan and stability. The belt buckle of this invention has a simple structure, with core components including only a base, a locking body, a lever, and a stop tooth. Compared to complex structures such as ratchet buckles, the number of parts is reduced, lowering the difficulty of production and assembly and reducing manufacturing costs. Furthermore, its one-handed operation design is suitable for users of different ages and physical strengths, possessing broad market application potential. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this utility model is to provide a belt buckle to solve the problems existing in the prior art and improve the ease of operation and structural reliability of the belt buckle.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6 As shown, this embodiment provides a belt buckle, including:

[0035] Matrix 1;

[0036] Locking body 2, the first end of locking body 2 is rotatably connected to one end of base body 1, a channel 9 is formed between locking body 2 and base body 1 for waist belt 11 to pass through, the second end of locking body 2 is far away from the first end, a stop tooth 4 for limiting the groove 12 on waist belt 11 is fixed on the side of the second end of locking body 2 near the channel 9, and the end of stop tooth 4 away from locking body 2 is farther away from the first end of locking body 2 than the other end of stop tooth 4.

[0037] The lever 3 has its first end rotatably connected to the second end of the locking body 2 on the side away from the channel 9. A placement groove 8 for placing the rear end of the belt 11 is formed between the lever 3 and the locking body 2, and the placement groove 8 is open at the second end of the locking body 2. Several locking pins 5 for pressing the rear end of the belt 11 are fixed on the side of the first end of the lever 3 near the placement groove 8. The first end of the locking body 2 can limit the middle part of the lever 3, and the contact point between the first end of the locking body 2 and the lever 3 serves as the fulcrum of the lever 3.

[0038] The specific method of using the belt buckle in this embodiment is as follows:

[0039] First, lever 3 is moved away from the first end of locking body 2 so that locking pin 5 on lever 3 rotates out of placement groove 8, providing clearance for placing the rear end of belt 11 in placement groove 8; then, the rear end of belt 11 is placed in placement groove 8, and lever 3 is moved closer to the first end of locking body 2 so that locking pin 5 on lever 3 presses the rear end of belt 11 into placement groove 8, thus fixing the rear end of belt 11; then, the front end of belt 11 is inserted into the aforementioned channel 9 from the end of base 1 near locking body 2, and exits the aforementioned channel 9 from the other end of base 1. After adjusting the waist, the stop tooth 4 on locking body 2 limits the groove 12 inside belt 11. Since the stop tooth 4 is inclined, the stop tooth 4 only prevents belt 11 from moving in the loosening direction. When it is necessary to tighten belt 11, the stop tooth 4 will not prevent belt 11 from moving, making it convenient to use;

[0040] When it is necessary to loosen the belt 11, the user pulls the lever 3 away from the locking body 2. The lever 3 causes the locking body 2 to rotate relative to the base 1, driving the stop tooth 4 to lift, thereby releasing the lock of the stop tooth 4 on the groove 12 of the belt 11 and loosening the belt 11. The design of the lever 3 utilizes the principle of mechanical lever 3, which greatly reduces the force required to release the stop tooth 4. Actual testing shows that compared with conventional belt buckles, it significantly reduces the operating force required for unlocking, effectively avoiding hand fatigue or damage to the belt 11 caused by excessive force, while also enhancing the service life and stability of the buckle.

[0041] It is worth noting that, Figures 1 to 6 The length of lever 3 shown is for illustrative purposes only. In actual applications, in order to reduce the operating force required for unlocking, technicians can make adaptive adjustments to the design length of lever 3 to ensure the best performance.

[0042] In this embodiment, the locking body 2 is rotatably connected to the base 1 via the first connecting pin 6; the first end of the lever 3 is rotatably connected to the locking body 2 via the second connecting pin 7. It is worth noting that in practical applications, it is not necessary to use connecting pins to achieve the rotatable connection between the locking body 2 and the base 1 and between the lever 3 and the locking body 2. It is also possible to achieve the rotatable connection between the locking body 2 and the base 1 and between the lever 3 and the locking body 2 through other means.

[0043] In the optional solutions of this embodiment, the more preferred one is as follows: Figure 5 and Figure 6 As shown, a limiting rod 10 is provided at the other end of the base 1. The limiting rod 10 is used to limit the waist belt 11 in the channel 9 along the thickness direction of the waist belt 11. The setting of the limiting rod 10 can prevent the waist belt 11 from slipping away from the channel 9, and ensure the stability and reliability of the waist belt buckle during use.

[0044] It is worth noting that in practical applications, the limiting rod 10 can be fixedly connected to the base 1, or both ends of the limiting rod 10 can be rotatably connected to the base 1. Fixing the limiting rod 10 to the base 1 fixes its posture and ensures stability during use. Rotating the limiting rod 10 to the base 1 allows it to rotate under friction with the belt 11 when the belt 11 is moved, increasing the enjoyment of use.

[0045] In the optional solutions of this embodiment, it is more preferred that the substrate 1 is frame-shaped. The frame-shaped substrate 1 has a simple structure, uses less material, and has low cost. Of course, in practical applications, technicians can make adaptive adjustments to the specific shape and appearance of the substrate 1 according to actual needs while ensuring the basic function of the substrate 1.

[0046] In this embodiment, the placement slot 8 is located inside the locking body 2, which allows the rear end of the belt 11 to be hidden inside the locking body 2, improving aesthetics.

[0047] In the optional scheme of this embodiment, it is more preferred that the lever 3 is plate-shaped and the locking pin 5 is conical, with the tip of the locking pin 5 far away from the lever 3; the plate-shaped lever 3 has a larger width, which increases the contact area between the user's finger and the lever 3 when the user turns the lever 3 with their finger, reduces the pressure per unit area of ​​the finger when turning it, and thus improves the comfort of use.

[0048] In the optional scheme of this embodiment, it is more preferred that the number of locking pins 5 is 7, and all the locking pins 5 are arranged sequentially along the width direction of the lever 3; the setting of multiple locking pins 5 can improve the stability of locking the rear end of the belt 11, and can also make the force on the rear end of the belt 11 as uniform as possible, so as to ensure the stability and fixation effect of the belt 11.

[0049] In the optional solutions of this embodiment, it is more preferred that the base 1, locking body 2, stop tooth 4 and lever 3 can be made of metal, plastic or other materials with sufficient structural strength and durability, such as stainless steel, aluminum alloy, engineering plastic, etc. The specific materials can be selected according to the actual application requirements.

[0050] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. 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 idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
