Description

Technical Field

[0001] This invention relates to the field of belt technology, and more specifically, to a composite adjustment buckle for a comfort belt. Background Technology

[0002] Leather belts, generally referring to waist belts made of leather, have become the mainstream in the market due to the international environmental protection concept, while the market share of genuine leather belts is gradually declining. As the world's largest exporter of belts, my country's products exported to the EU, the US and other regions must meet strict environmental protection and non-toxic standards, with clear requirements on material safety and environmental protection of production processes.

[0003] Existing belts generally use single locking structures such as pin buckles and rack and pinion buckles. Adjustment relies on fixed holes or rack positions, which cannot achieve millimeter-level precise fit. At the same time, the locking relies on a single meshing or friction action. In high-intensity scenarios such as vigorous exercise and large movements, the locking is prone to failure due to impact, resulting in the belt loosening or slipping off, and failing to guarantee stable fixation. On the other hand, some belts use strong locking structures to improve reliability. Although the locking is secure, it is cumbersome to operate when quickly putting on and taking off in daily life, has poor adaptability, and cannot balance the dual needs of quick positioning in daily life and stable locking under high intensity. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a comfort belt composite adjustment buckle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comfortable waist belt composite adjustment buckle, comprising a first buckle and a second buckle, wherein the top surface of the second buckle is provided with a perforation, the outer side of the first buckle is sewn with fabric, the bottom of the fabric is provided with a rubber-coated part, the top surface of the rubber-coated part is provided with a notch, the inner wall surface of the notch is provided with a groove, a webbing is provided between the first buckle and the second buckle, a protective cover is hinged to the top of the first buckle, and a winding rod for winding the webbing is fixedly connected inside the first buckle;

[0006] A fully locking mechanism is provided between the first fastener and the webbing; a spring-loaded locking mechanism is provided inside the first fastener; and a magnetic locking mechanism is provided on the outside of the webbing.

[0007] The fully locking mechanism includes an adjusting slide rail located on the bottom surface of the webbing and installed inside the webbing. The adjusting slide rail has multiple toothed grooves inside. A fixed housing is fixedly connected to one side of the first fastener. A threaded rod is rotatably connected inside the fixed housing. A knob is fixedly connected to one end of the threaded rod, and a threaded sleeve is threadedly connected to the other end of the threaded rod. A moving block is fixedly connected to the bottom of the threaded sleeve. A moving clamping plate for clamping the webbing is fixedly connected to the bottom of the moving block. Multiple friction blocks are fixedly connected to the bottom of the moving clamping plate. A through groove is opened on one side surface of the first fastener.

[0008] Preferably, the spring-loaded locking mechanism includes two fixing plates, both of which are fixed to one side of the inner wall of the first fastener, and a fixing shaft is fixedly connected between the two fixing plates.

[0009] Preferably, a rotating sleeve is provided on the outer side of the fixed shaft, a torsion spring is fixedly installed between the rotating sleeve and the fixed plate, and a latch is fixedly connected to one side of the rotating sleeve.

[0010] Preferably, the latch and the adjusting slide rail are in sliding engagement, and the latch alternately engages or disengages with multiple toothed grooves during sliding. The distance between each pair of toothed grooves is 1 mm, and the multiple toothed grooves are evenly arranged along the length direction of the adjusting slide rail.

[0011] Preferably, the magnetic locking mechanism includes multiple low-carbon steel sheets, which are uniformly fixed on the top surface of the webbing, and a magnet is fixedly installed inside one end of the webbing.

[0012] Preferably, the threaded sleeve is fixedly connected to both sides with limiting slide rods, and the inner wall of the fixed shell is provided with limiting slide grooves on both sides, and the limiting slide rods are slidably connected to the limiting slide grooves.

[0013] Preferably, the friction block is used to increase the friction between the movable clamp and the webbing, and the movable block is slidably connected to the through groove.

[0014] Preferably, a silicone plate is provided at the bottom of the fabric on the outside of the coated part.

[0015] Preferably, the overmolded part is a TPU overmolded part.

[0016] Preferably, a hot melt adhesive film is provided on the top surface of the silicone plate and the coated part that contacts the fabric.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. The snap-lock mechanism achieves temporary positioning through the engagement of the latch and the tooth groove, ensuring that the webbing does not slide arbitrarily during adjustment. In the magnetic locking mechanism, the magnet at one end of the webbing and the low-carbon steel plate at the top generate an attraction force for quick attraction and locking. The fully locking mechanism uses a threaded rod to drive the moving clamp and the winding rod to hold the webbing. Combined with the resistance increase effect of the friction block and the secondary engagement of the latch and the tooth groove, the three locking structures together form a two-way rigid locking of tooth groove engagement, magnetic attraction and mechanical clamping. This solves the pain points of traditional belt locking being weak and easy to loosen, and can maintain stable fixation even in special scenarios of vigorous movement. Temporary positioning is achieved through the engagement of the latch and the tooth groove, which is suitable for daily quick positioning scenarios. Simply pull the webbing to achieve initial temporary positioning, improving the convenience of use. Initial fixation during wearing can be completed with one hand, which is especially suitable for scenarios with obstructed vision or one-handed operation, improving the use effect. The three levels of constraint correspond to medium, daily use and high intensity scenarios, which not only avoids the cumbersome operation of a single strong lock, but also solves the reliability problem of a single weak lock, realizing one buckle for multiple uses.

[0019] 2. The snap-lock mechanism, through the cooperation of the latch and the tooth groove, enables the adjustment accuracy of the webbing to reach 1mm level, which solves the problem of the fixed adjustment position of the traditional waist belt and the inability to accurately fit the waist size. At the same time, the preload of the torsion spring produces a clear click feedback when the latch and the tooth groove are engaged. Users can intuitively perceive the adjustment progress through touch and hearing, avoiding blind pulling and improving adjustment efficiency and accuracy.

[0020] 3. The outer fabric of the first fastener comes into contact with the human body, and the silicone plate at the bottom is fixed by hot melt adhesive film. Together with the TPU-coated parts and silicone plate, it reduces the pressure of metal or hard materials directly contacting the skin. At the same time, the anti-slip properties of silicone prevent the adjustment buckle from shifting when wearing. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] As attached Figure 1-6 The comfort belt composite adjustment buckle shown includes a first buckle 1 and a second buckle 2. The top surface of the second buckle 2 has a perforation 3. The outer side of the first buckle 1 is sewn with fabric 4. The bottom of the fabric 4 is provided with a rubber-coated part 5. The top surface of the rubber-coated part 5 has a notch 6. The inner wall surface of the notch 6 has a groove 7. A webbing 8 is provided between the first buckle 1 and the second buckle 2. The top of the first buckle 1 is hinged with a protective cover 9. A winding rod 10 for winding the webbing 8 is fixedly connected inside the first buckle 1.

[0030] A fully locking mechanism is provided between the first fastener 1 and the webbing 8. A spring-loaded locking mechanism is provided inside the first fastener 1, and a magnetic locking mechanism is provided on the outside of the webbing 8.

[0031] The fully locking mechanism includes an adjusting slide rail 11, which is located on the bottom surface of the webbing 8 and installed inside the webbing 8. The adjusting slide rail 11 has multiple toothed grooves 12 inside. A fixed housing 13 is fixedly connected to one side of the first fastener 1. A threaded rod 14 is rotatably connected inside the fixed housing 13. A knob 15 is fixedly connected to one end of the threaded rod 14. A threaded sleeve 16 is threadedly connected to the other end of the threaded rod 14. A moving block 17 is fixedly connected to the bottom of the threaded sleeve 16. A moving clamping plate 18 for clamping the webbing 8 is fixedly connected to the bottom of the moving block 17. Multiple friction blocks 19 are fixedly connected to the bottom of the moving clamping plate 18. A through groove 20 is opened on one side surface of the first fastener 1.

[0032] As attached Figure 6As shown, the spring-loaded locking mechanism includes two fixed plates 21, both of which are fixed to one side of the inner wall of the first fastener 1. A fixed shaft 22 is fixedly connected between the two fixed plates 21. A rotating sleeve 23 is rotatably sleeved on the outside of the fixed shaft 22. A torsion spring 24 is fixedly installed between the rotating sleeve 23 and the fixed plate 21. A latch 25 is fixedly connected to one side of the rotating sleeve 23. The latch 25 slides in cooperation with the adjusting slide rail 11. When sliding, the latch 25 alternately engages or disengages with multiple toothed grooves 12. The distance between each pair of toothed grooves 12 is 1 mm. The multiple toothed grooves 12 are evenly arranged along the length of the adjusting slide rail 11 to facilitate the latch 25 to rebound. The preload of the torsion spring 24 produces a clear snapping feedback when the latch 25 engages with the toothed grooves 12, improving the adjustment efficiency and adjustment accuracy.

[0033] As attached Figure 1 , 3 As shown in Figure 5, the magnetic locking mechanism includes multiple low-carbon steel sheets 26, which are evenly fixed on the top surface of the webbing 8. A magnet 27 is fixedly installed inside one end of the webbing 8 to facilitate quick positioning and locking, achieving approximate locking, and is suitable for rapid use scenarios.

[0034] As attached Figure 6 As shown, the threaded sleeve 16 is fixedly connected to both sides of the limiting slide rod 28, and the inner wall of the fixed shell 13 is provided with both sides of the limiting slide groove 29. The limiting slide rod 28 and the limiting slide groove 29 are slidably connected to each other, which plays a limiting role, so that the threaded sleeve 16, the moving block 17 and the moving clamping plate 18 will not rotate, which makes it easy to clamp and lock the webbing 8.

[0035] As attached Figure 6 As shown, the friction block 19 is used to increase the friction between the movable clamping plate 18 and the webbing 8. The movable block 17 is slidably connected to the through groove 20 to increase the friction and improve the locking effect of the movable clamping plate 18 on the webbing 8.

[0036] As attached Figure 1-5 As shown, a silicone plate 30 is provided at the bottom of the fabric 4 on the outside of the overcoated part 5. The overcoated part 5 is a TPU overcoated part. A hot melt adhesive film 31 is provided on the contact surface between the silicone plate 30 and the top of the overcoated part 5 and the fabric 4, which facilitates a stable connection between the silicone plate 30 and the overcoated part 5 and the fabric 4, and improves the softness of the silicone plate 30 and the overcoated part 5 in contact with the body, thereby improving comfort.

[0037] Working principle of the invention: The comfort belt composite adjustment buckle achieves the wearing and adjustment of the belt through the synergistic action of the first buckle 1 and the second buckle 2. The second buckle 2 allows the webbing 8 to pass through the perforation 3. The first buckle 1 contacts the human body through the fabric 4 sewn on the outside. The rubber-coated part 5 at the bottom of the fabric 4 can be embedded into the corresponding structure of the second buckle 2. The groove 7 on the inner wall of its notch 6 is used for auxiliary positioning. The protective cover 9 on the top of the first buckle 1 can protect the internal structure. The internal winding rod 10 is used to wind the webbing 8 to adjust the length. The silicone plate 30 at the bottom of the fabric 4 is fixed to the fabric 4 by the hot melt adhesive film 31, which enhances the comfort and anti-slip properties when wearing.

[0038] The snap-locking mechanism is the basic adjustment unit of the adjustment buckle. The webbing 8 is positioned stepwise by the engagement of the latch 25 and the toothed groove 12. The fixing plate 21 is fixed to the inner wall of the first fastener 1. A rotating sleeve 23 is sleeved on the outside of the fixing shaft 22 between the two fixing plates 21. The torsion spring 24 between the rotating sleeve 23 and the fixing plate 21 provides a continuous preload force, so that the latch 25 on one side of the rotating sleeve 23 always tends to fit towards the webbing 8. The adjustment slide rail 11 built into the bottom surface of the webbing 8 has multiple evenly arranged adjacent toothed grooves 12 with a spacing of 1mm. When the webbing 8 is pulled to adjust the length, the latch 25 slides along the adjustment slide rail 11 and alternately engages or disengages with the toothed groove 12. When engaged, the preload force of the torsion spring 24 causes the latch 25 to engage with the toothed groove 12, generating a snapping feedback and achieving temporary positioning. When sliding, the external force overcomes the preload force and causes the latch 25 to disengage from the toothed groove 12, completing the fine adjustment with a precision of 1mm.

[0039] After the spring-loaded locking mechanism completes its basic adjustment, the fully locking mechanism achieves complete fixation of the webbing 8 through mechanical clamping. A threaded rod 14 is provided in the fixing shell 13 on one side of the first fastener 1. One end of the rod is connected to the knob 15, and the other end is threadedly engaged with the threaded sleeve 16. The limiting slide rods 28 on both sides of the threaded sleeve 16 slide along the limiting slide groove 29 on the inner wall of the fixing shell 13 to ensure that the threaded sleeve 16 moves only axially. When the knob 15 is rotated, the threaded rod 14 drives the threaded sleeve 16 to move the moving block 17 along the through slide groove 20, so that the moving clamp 18 at the bottom of the moving block 17 moves closer to the winding rod 10. The friction block 19 at the bottom of the moving clamp 18 and the winding rod 10 clamp the webbing 8 together. At the same time, the toothed groove 12 in the adjusting slide rail 11 engages with the latch 25 for a second time to achieve bidirectional rigid locking of the webbing 8.

[0040] The magnetic locking mechanism on the outside of the webbing 8 is used to improve the positioning efficiency when wearing it. The low carbon steel sheet 26 that is uniformly fixed on the top surface of the webbing 8 can be attracted by the magnet 27 inside one end of the webbing 8. When the webbing 8 passes through the hole 3 of the second buckle 2 and moves closer to the first buckle 1, the magnetic attraction between the magnet 27 and the low carbon steel sheet 26 guides the webbing 8 to quickly align with the adjustment slide rail 11, reducing the operation cost of manual alignment, and is especially suitable for single-hand wearing scenarios.

[0041] Pass the webbing 8 through the hole 3 of the second fastener 2, pull the webbing 8 to bring the first fastener 1 closer to the waist, magnet 27 and low carbon steel sheet 26 magnetically align, rubber-coated part 5 is embedded in the corresponding structure of the second fastener 2, and the slot 7 assists in initial fixation. By pulling the webbing 8, the latch 25 slides along the toothed groove 12 of the adjustment slide rail 11 with feedback every 1mm, adjusting to the tightness that fits the waist, and making fine adjustments. Rotate the knob 15 to drive the moving clamp 18 and the winding rod 10 to clamp the webbing 8, achieving bidirectional rigid locking. The silicone plate 30 and the rubber-coated part 5 reduce the pressure on the skin. Rotate the knob 15 in the opposite direction, the moving clamp 18 disengages from the webbing 8, and the latch 25 can slide along the toothed groove 12 again under the action of the torsion spring 24. Repeat the adjustment process. This adjustment buckle achieves a comfortable experience throughout the entire process of quick positioning, fine adjustment and rigid locking, ensuring the unity of adjustment accuracy, locking reliability and wearing comfort.
