Abstract
Description
Technical Field
[0001] This utility model relates to a device for human fitness and exercise, and in particular to a weighted belt that can be worn on the wrist, ankle or waist to achieve fitness effects by bearing weight. Background Technology
[0002] Weighted rings, a common type of exercise equipment, are primarily worn on the wrists, ankles, and other areas to increase exercise intensity by adding weight, thereby enhancing muscle strength, improving cardiovascular function, and promoting fat burning. They typically consist of a band, a counterweight structure, and a connecting structure. The design of the connecting structure directly affects the stability, comfort, and ease of use, and is a key area for continuous optimization within the industry.
[0003] In the prior art, there are various forms of connection methods for the strap of a weight-bearing ring. For example, the "weight-bearing wristband" with patent number CN219149142U discloses a structure that uses Velcro for connection. This structure includes a strip, an end block, and a locking structure. The sub-locking structure (rounded surface) of the locking structure is located on the strip, and the female locking structure (ragged surface) is set on the surface of the end block. The strip is fixed by the adhesion of the two.
[0004] Another type, such as the "weight-adjustable load-bearing bracelet" with patent number CN 219501930 U, uses a pinhole plug-in structure for connection. Specifically, one end of the load-bearing part is provided with a connecting buckle, and the connecting part is provided with multiple connecting holes. The connection and tightness adjustment of the strap are achieved by the cooperation of the connecting buckle and the connecting holes.
[0005] However, both of the above connection methods have certain drawbacks. While the Velcro connection is relatively simple to operate, over long-term use, the rounded surface of the Velcro is prone to wear and tear, dust accumulation, and decreased adhesion, leading to a looser fit and affecting stability. The pinhole connection, although more secure and less prone to loosening, requires precise alignment of the buckle and hole for adjustment or disassembly, and the separation process requires external force, making it relatively cumbersome and inconvenient for users. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a load-bearing belt that is convenient for both connection and separation operations.
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a load-bearing belt that is convenient for connection and separation operations, including a belt part and a connecting buckle connected to one end of the belt part. The belt part is made of a flexible elastic material and is divided into two parts: a counterweight section and a connecting section. The counterweight section and the connecting section are an integral structure or fixedly connected. At least one counterweight block is fixedly installed on the counterweight section. The counterweight blocks are distributed along the length direction of the counterweight section. The connecting section includes a base belt with opposite first and second surfaces. The first surface of the base belt is provided with a plurality of raised first teeth, which are spaced apart along the length direction of the base belt. The second surface of the base belt is provided with a plurality of raised second teeth, which are also spaced apart along the length direction of the base belt.
[0008] The connecting buckle has a slot for the connecting segment to pass through. The size of the slot is adapted to the width of the connecting segment, and the inner side of the slot has a locking structure that matches the first tooth and the second tooth. When the connecting segment passes through the slot, the first tooth and the second tooth on the connecting segment engage with the corresponding locking structure on the inner side of the slot, so that the load-bearing belt can form a loopable ring structure.
[0009] When it is necessary to untangle the ring structure, pull the connecting segment away from the slot to release the engagement between the first tooth, the second tooth and the slot, and the connecting segment will be pulled out of the slot.
[0010] A further technical solution of this utility model is: the first teeth on the first surface and the second teeth on the second surface are symmetrically arranged with respect to the baseband.
[0011] A further technical solution of this utility model is as follows: the first tooth is formed by a first inclined surface and a first vertical surface, the first vertical surface being perpendicular to the extension surface of the baseband; the second tooth is formed by a second inclined surface and a second vertical surface, the second vertical surface being perpendicular to the extension surface of the baseband.
[0012] A further technical solution of this utility model is as follows: the counterweight section includes multiple interconnected parcel units, each parcel unit is provided with a counterweight compartment, the counterweight block is placed in the compartment, and adjacent parcel units are connected by a narrow band.
[0013] A further technical solution of this utility model is as follows: the connecting buckle includes a rectangular frame, the rectangular frame is provided with a lower tooth and an upper tooth, the slot is formed between the lower tooth and the upper tooth, the inner side of the upper tooth is a third inclined surface, the outer side of the upper tooth is a third vertical surface, the inner side of the lower tooth is a fourth inclined surface, and the outer side of the lower tooth is a fourth vertical surface.
[0014] A further technical solution of this utility model is as follows: the thickness from the first tooth to the second tooth is L1, the thickness of the base strip is L2, and the height of the groove is L3, where L1>L3>L2.
[0015] Another technical solution adopted by this utility model to solve the above-mentioned technical problems is: a load-bearing belt that is convenient for connection and separation operations, including a belt part and a connecting buckle connected to one end of the belt part. The belt part is made of a flexible elastic material and is divided into two parts: a counterweight section and a connecting section. The counterweight section and the connecting section are an integral structure or fixedly connected. At least one counterweight block is fixedly installed on the counterweight section. The counterweight blocks are distributed along the length direction of the counterweight section. The connecting section includes a base belt. The base belt has a first surface and a second surface that are arranged opposite to each other. A plurality of protruding teeth are provided on at least one surface of the base belt. The teeth are arranged at intervals along the length direction of the base belt.
[0016] The connecting buckle has a slot, the size of which is adapted to the width of the connecting section, allowing the connecting section to pass through. When the connecting section passes through the slot, the teeth on the connecting section can engage with the locking structure inside the slot, thereby forming a loopable ring structure for the load-bearing belt.
[0017] When it is necessary to untangle the ring structure, pull the connecting segment away from the slot. The connecting segment can be pulled out of the slot, and the engagement between the teeth and the slot is released.
[0018] A further technical solution of this utility model is that the toothed part includes an inclined surface and a vertical surface.
[0019] A further technical solution of this utility model is as follows: the counterweight section includes multiple interconnected parcel units, each parcel unit is provided with a counterweight compartment, the counterweight block is placed in the compartment, and adjacent parcel units are connected by a narrow band.
[0020] A further technical solution of this utility model is as follows: the connecting buckle includes a rectangular frame, the rectangular frame is provided with a lower tooth and an upper tooth, and the groove is formed between the lower tooth and the upper tooth.
[0021] Compared with existing technologies, the advantages of this utility model are: the load-bearing belt achieves a highly stable locking effect through a unique structural design. The first and second surfaces of the base belt of the connecting section are respectively provided with raised first and second teeth arranged at intervals along the length direction, while the inner side of the groove of the connecting buckle is provided with a matching engaging structure. When the connecting section passes through the groove, the first and second teeth can tightly engage with the engaging structure inside the groove, forming a stable locking effect. This technical means ensures that the load-bearing belt will not loosen during movement, improving the stability and safety of use.
[0022] While ensuring stable locking, this load-bearing belt also features a convenient unlocking function. When it is necessary to disengage the ring structure, simply pull the connecting section away from the slot; the first and second teeth will then separate from the locking mechanism within the slot, allowing the connecting section to be easily pulled out. This makes the unlocking process simple and quick, eliminating the need for complicated operations and improving the user experience.
[0023] This weight-bearing belt is designed with mechanical performance and user experience in mind. The base band, made of a flexible material, not only offers excellent flexibility but also absorbs impact to a certain extent, reducing discomfort during exercise. Furthermore, the well-designed dimensions between the base band and the slot ensure smooth sliding of the connecting section as it passes through the slot, reducing sliding friction, minimizing wear, and extending the product's lifespan. This also allows the weight-bearing belt to better conform to the body's curves, improving wearing comfort. Attached Figure Description

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0041] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.
[0042] like Figures 1 to 4 The diagram shows the wearing and unfolded states of the weighted belt 100. The weighted belt 100 includes a belt portion 101 and a connecting buckle 102 connected to one end of the belt portion 101. The belt portion 101 is made of a flexible material and is divided into a counterweight section 101a and a connecting section 101b. The counterweight section 101a and the connecting section 101b are an integral structure or fixedly connected. At least one counterweight block 80 is fixedly installed on the counterweight section 101a, and the counterweight blocks 80 are distributed along the length direction of the counterweight section 101a.
[0043] Specifically, the connecting segment 101b includes a base band 10 having opposing first surfaces s1 and second surfaces s2. The first surface s1 of the base band 10 is provided with a plurality of raised first teeth a, which are spaced apart along the length of the base band 10. The second surface s2 of the base band 10 is provided with a plurality of raised second teeth b, which are also spaced apart along the length of the base band 10. The connecting buckle 102 is provided with a slot 20 for the connecting segment 101b to pass through. The size of the slot 20 is adapted to the width of the connecting segment 101b, and the inner side of the slot 20 is provided with a locking structure f that matches the first teeth a and the second teeth b.
[0044] Preferably, after the connecting segment 101b passes through the slot 20, the first tooth a and the second tooth b on the connecting segment 101b engage with the corresponding engaging structure f inside the slot 20, thereby enabling the load-bearing strap 100 to form a loopable ring structure r. This technical feature not only simplifies the wearing process, allowing for fixation without additional tools, but also enhances the product's load-bearing capacity and increases the safety factor through a self-locking mechanism that tightens as it is pulled.
[0045] It should be noted that when the ring structure needs to be untied, pulling the connecting segment 101b away from the slot 20 will release the engagement between the first tooth a, the second tooth b, and the slot 20, allowing the connecting segment 101b to be pulled out of the slot 20. This technical feature reduces the resistance generated by the inclined surface during untiing, making it easier to release the locked state. At the same time, the baseband 10 absorbs some of the impact force during the stretching phase, avoiding the jerky feeling caused by unlocking and improving the user's wearing experience.
[0046] like Figures 5 to 8 The diagram shows the load-bearing belt in use. The first tooth a on the first surface s1 and the second tooth b on the second surface s2 are symmetrically arranged relative to the base belt 10. The first tooth a is formed by a first inclined surface a1 and a first vertical surface a2, with the first vertical surface a2 perpendicular to the extension surface of the base belt 10. This technique allows the teeth on both sides to simultaneously engage with the engaging structure f, distributing the circumferential tension evenly across the two engagement lines, improving product stability. Simultaneously, the base belt 10 slides out in a straight line along the axis within the slot 20 without swaying, reducing unlocking resistance.
[0047] The aforementioned technical means ensure that the thickness center plane of the base belt 10 is kept on the geometric center line of the slot 20, reducing wear from unilateral load. At the same time, the double-row symmetrical teeth and flexible counterweight work together to improve the reliability and comfort of the load belt.
[0048] Furthermore, the counterweight section 101a includes multiple interconnected wrapping units 30, each wrapping unit 30 having a counterweight compartment 31. Counterweight blocks 80 are placed within the compartment 31, and adjacent wrapping units 30 are connected by narrow straps 40. This technique allows the counterweight blocks 80 to be evenly distributed along the length of the counterweight section 101a, thus achieving a stable load distribution. During exercise, the weight distribution of the load belt is more uniform, preventing localized overload due to concentrated counterweight blocks, thereby improving wearing comfort and stability.
[0049] Moreover, with the aforementioned technologies, trainees can flexibly adjust the number and position of the weights according to their training needs and strength levels. Users can add or remove weights, or adjust the distribution of weights across the weight range, to achieve the best training effect. This flexibility allows the weight belt to adapt to the personalized needs of different users.
[0050] like Figures 9 to 11 The diagram shows a sectional view of the side structure of the load-bearing belt. The connecting buckle 102 includes a rectangular frame 50, within which are a lower toothed portion c and an upper toothed portion d. A groove 20 is formed between the lower toothed portion c and the upper toothed portion d. The inner surface of the upper toothed portion d is a third inclined surface d1, and the outer surface of the upper toothed portion d is a third vertical surface d2. The inner surface of the lower toothed portion c is a fourth inclined surface c1, and the outer surface of the lower toothed portion c is a fourth vertical surface c2. The thickness from the first toothed portion a to the second toothed portion b is L1, the thickness of the base belt 10 is L2, and the height of the groove 20 is L3; L1>L3>L2.
[0051] This technology allows the first tooth a and the second tooth b to engage tightly with the locking structure within the slot 20, achieving a stable locking effect. Simultaneously, the baseband 10 reduces sliding friction as it passes through the slot 20. During wearing and unwearing, the baseband 10 slides more smoothly without jamming or wear due to excessive friction, thus improving the user experience and making the wearing and unwearing process easier and faster.
[0052] Furthermore, the weighted belt in this embodiment will not cause pressure marks or numbness even after prolonged wear, improving the user experience and making it suitable for weight training needs of different intensities in multiple parts such as the wrist and ankle.
[0053] It should also be noted that the load-bearing belt of this utility model achieves a highly efficient locking effect through a specifically designed toothed section and engaging structure. Specifically, the inclined surfaces of the upper toothed section d and the lower toothed section c of the groove 20 of the connecting buckle 102 can slide smoothly and continuously to the desired position based on the inclined surfaces of the first toothed section a and the second toothed section b of the connecting segment 101b. After sliding into place, the vertical surface of the groove 20 (the third vertical surface d2 and the fourth vertical surface c2) will precisely self-lock and engage with the vertical surface of the toothed section (the first vertical surface a2 and the second vertical surface b2). This process benefits from the axial connection design of the connecting buckle 102, which allows the load-bearing belt to be in a pre-circular state when worn. The connecting buckle 102 will automatically rotate to the first direction, and the inclined surfaces of the groove 20 (the third inclined surface d1 and the fourth inclined surface c1) and the inclined surfaces of the toothed section (the first inclined surface a1 and the second inclined surface b1) will be approximately in the same inclined direction, making it easier to slide to the desired position. In the annular state, the vertical surface of the groove 20 and the vertical surface of the teeth can more fully and comprehensively limit each other, ensuring the stability and safety of the load-bearing belt during movement.
[0054] The unlocking process is equally convenient. The user simply needs to manually rotate the connecting buckle 102 to the second direction. At this point, the vertical surfaces of the slot 20 (the third vertical surface d2 and the fourth vertical surface c2) and the vertical surfaces of the teeth (the first vertical surface a2 and the second vertical surface b2) are not fully engaged or locked. Furthermore, because the connecting section 101b is made of a flexible material with a certain degree of deformability, the user can easily slide the connecting buckle 102 off the connecting section 101b by applying a certain amount of external force. This not only improves the convenience of unlocking but also reduces the jerking sensation during unlocking, enhancing the user's wearing experience.
[0055] like Figures 12 to 15 The diagram shows a load-bearing band 100 with other tooth shapes. The cross-section of the tooth shape can be semi-circular, semi-circular, rectangular, or rectangular. Different tooth cross-sections, such as semi-circular, semi-circular, rectangular, and rectangular, can be embedded in the engaging structure f and produce equivalent technical functions. Semi-circular shapes reduce stress concentration, while rectangular shapes increase rigidity. Users can select different tooth shapes according to load levels or training scenarios without modifying other structures of the base band 10 or connecting buckle 102. The tooth cross-section shape is open and compatible, adapting to users' personalized needs.
[0056] Preferably, to enhance user experience and ensure focus during training, the weighted belt 100 is equipped with a positioning ring. This technology secures the excess length of the connecting segment 101b within the positioning ring, effectively preventing any swaying or interference that might occur with the excess portion in its free state, thus ensuring that the user can remain undisturbed and focus on their workout.
