Description

Technical Field

[0001] This utility model relates to the field of belt technology, specifically a belt with a nylon-coated steel sheet structure that can be quickly disassembled and assembled. Background Technology

[0002] Belts, as common functional accessories in the apparel industry, are widely used for securing trousers, workwear, and outdoor gear. Traditional belts typically use a combination of metal buckles and eyelets with a locking mechanism to achieve length adjustment. This design suffers from low assembly and disassembly efficiency, requiring repeated unbuckling and unlocking each time the belt is worn. In particular, belts with locking mechanisms often result in inconsistent waist length adjustments each time, leading to discomfort and requiring repeated adjustments, thus presenting certain drawbacks. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-release belt with a nylon-coated steel sheet structure. It has the advantages of improving the speed of belt assembly and disassembly, and eliminating the need for repeated adjustments after the initial adjustment of the appropriate waist length. This solves the problems of slow belt assembly and disassembly speed and the need for repeated waist length adjustments every time the belt is worn.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release waist belt with a nylon-coated steel sheet structure, comprising a front buckle plate, a waist belt, and a rear buckle plate. One end of the front buckle plate has an installation groove, and a retaining hole is provided on one side of the front buckle plate. The retaining hole communicates with the installation groove, and a screw is threaded into the retaining hole. Two retaining holes are equidistantly provided at one end of the front side of the front buckle plate, and a screw is threaded into the retaining hole. By rotating the screw in both directions, the depth to which the screw moves into the installation groove can be adjusted.

[0007] The mounting slot is movably fitted onto one end of the waist belt, and one end of the screw is attached to the corresponding position on the side of the waist belt. The width and thickness of the waist belt match the size of the mounting slot. By inserting one end of the waist belt into the mounting slot and rotating the screw nut, the screw shank gradually moves into the mounting slot and fits tightly against the corresponding position on the side of the waist belt, thus fixing the waist belt to the front buckle plate.

[0008] The back of the front buckle plate has a groove, and a connecting groove is formed in the groove. A front magnetic block is fixed in the connecting groove. The connecting groove is located in the center of the groove, and a front magnetic block of the same size is installed in the connecting groove.

[0009] A rear buckle is movably connected to the back of the front buckle. A groove 2 is provided on the front side of the rear buckle. An installation frame is provided in the groove 2. A rear magnetic block is fixed in the installation frame. The rear magnetic block is positioned opposite the front magnetic block. The installation frame is located in the center of the groove 2. A rear magnetic block of the same size is installed in the installation frame. When the front buckle and the rear buckle are closed, the front magnetic block and the rear magnetic block are opposite each other and magnetically fixed.

[0010] Side plates are provided on both sides of the back of the rear buckle plate. Guide plates and limiting plates are fixed at both ends of the side plates respectively. A locking mechanism is movably connected in the limiting plate. The guide plate is used to guide one end of the waist belt to pass through the back of the rear buckle plate and between the guide plate, so that it can stably pass through the limiting plate during continuous guiding and conveying, and be locked and fixed by the locking mechanism.

[0011] The belt has a movable steel plate inside, which is made of stainless steel and can be attracted and fixed by magnetic objects. The steel plate also has a certain degree of flexibility and can be bent freely, so it can be worn stably around the user's waist.

[0012] Furthermore, during disassembly, the flexible and springy force of the steel sheet can be used to separate the front and rear buckle plates, increasing the belt disassembly speed.

[0013] When using this quick-release belt, one end of the belt is inserted into the mounting slot, and a screw is inserted into the retaining hole. The screw is then rotated so that the front end of the screw is pressed against the corresponding position on the side of the belt, thus fixing one end of the belt to the front buckle plate. At this time, the rear buckle plate is fixed by mutual attraction between the front buckle plate and the rear buckle plate. Then, the other end of the belt is passed through the rear buckle plate between the guide plate and the limiting plate and tightened to a suitable tightness. It is then fixed by the locking mechanism. For quick disassembly, the front buckle plate and the rear buckle plate are pushed in opposite directions, causing the limiting clip on the retaining button to separate from the limiting piece. At the same time, the buckle rises along the inclined section, causing the magnetic block to separate, thus completing the disassembly.

[0014] As a further improvement to the above solution, a sloping section is provided on the front buckle plate at one end of the groove.

[0015] On the rear buckle plate, a slanted section two is provided at one end of the groove two.

[0016] The opposite faces of inclined section one and inclined section two are set parallel to each other.

[0017] With the above technical solution, when the front and rear buckles are closed, the first inclined section and the second inclined section are opposite and fit together. When they are separated, the front buckle separates from the rear buckle by sliding along the inclined section. When they are joined, the front buckle joins the rear buckle by sliding along the inclined section.

[0018] As a further improvement to the above scheme, side strips are provided on both sides of the groove 2, and the two sides of the groove 1 are attached to the opposite outer side of the side strips.

[0019] With the above technical solution, when the front and rear buckles are closed or separated, the edge strip slides against the inner side of the groove, thereby ensuring the stability of the sliding connection between the front and rear buckles and thus ensuring accurate alignment of the front and rear magnetic blocks.

[0020] As a further improvement to the above solution, a retaining groove is provided at one end of the groove, the retaining groove penetrates the surface of the front buckle plate, and a limiting piece is provided at one end of the retaining groove.

[0021] A retaining button is fixed at one end of the groove, and a limit slot is provided on the side of the retaining button.

[0022] The retaining button is movably connected in the retaining slide groove, and the limiting slot is engaged with the side of the limiting piece.

[0023] Through the above technical solution, the front buckle and the rear buckle are separated and merged by sliding, so that the fixing button slides in the fixing groove. When the limiting slot is engaged with the side of the limiting piece, it plays the role of locking and fixing the front buckle and the rear buckle after they are merged.

[0024] As a further improvement to the above solution, a protruding button is provided at one end of the back of the front buckle, and a guide groove is provided at one end of the rear buckle, located in the second groove, with the protruding button movably connected in the guide groove.

[0025] With the above technical solution, when the front and rear buckle plates are combined and separated, the convex button slides in the guide groove, which improves the stability of the connection between the buckle plates and avoids the phenomenon of shifting to the side.

[0026] As a further improvement to the above solution, the locking mechanism includes a connecting rod rotatably connected between the side plates, and the side of the connecting rod is fixed with a toothed buckle.

[0027] The belt has a groove on the side, and the side of the buckle engages with the side of the groove.

[0028] With the above technical solution, when the connecting rod rotates, it drives the side buckle to rotate at the same time. When the front end of the buckle disengages from the corresponding strip groove on the side of the belt, the belt can be pushed and pulled freely to adjust the waist size of the belt. When the front end of the buckle engages in the corresponding strip groove on the side of the belt, it can fix the adjusted waist size.

[0029] As a further improvement to the above solution, torsion springs are movably sleeved on the sides of both ends of the connecting rod, and the two ends of the torsion springs are fixed between the toothed buckle and the side plate, respectively.

[0030] Through the above technical solution, the torsion spring is used to reverse the twisting of the toothed buckle, so that the front end of the toothed buckle remains engaged in the corresponding slot.

[0031] As a further improvement to the above solution, a button is fixed to one end of the connecting rod, and the button is attached to the side of the side plate.

[0032] With the above technical solution, by turning the button, the connecting rod drives the toothed buckle to rotate, and the front end of the toothed buckle disengages from the strip groove. At this time, the torsion spring tightens. When the button is released, the torsion spring releases the torque, causing the connecting rod to drive the toothed buckle to rotate in the opposite direction, so that the toothed buckle engages in the corresponding strip groove.

[0033] As a further improvement to the above solution, the steel sheet is a high-manganese steel sheet.

[0034] As a further improvement to the above solution, the steel sheet is hardened to improve its wear resistance.

[0035] Compared with the prior art, this utility model provides a quick-release belt with a nylon-coated steel sheet structure, which has the following advantages:

[0036] 1. This quick-release belt features a front buckle plate and a rear buckle plate. It uses magnetic attraction technology in conjunction with the limiting slot on the side of the retaining button and the limiting piece in the retaining groove to lock in place. Quick disassembly is achieved by pushing the two buckle plates in opposite directions.

[0037] 2. This quick-release waist belt is fixed to the front buckle plate at the front end, and the other end passes between the rear guard plate, guide plate, and limit plate. After being fixed by the buckle mechanism, after the initial adjustment to the appropriate waist length, the two buckles are simply placed together, the magnetic block is attracted and fixed, and the limit plate is engaged with the side of the limit plate to achieve fixation. The two buckles are pushed in opposite directions to quickly separate, thus eliminating the need to repeatedly adjust the waist length each time it is worn, further improving the practicality of the waist belt.

[0038] 3. This quick-release belt features steel plates that increase its strength, allowing for the hanging of various weights and facilitating outdoor use. Attached Figure Description

[0050] 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.

[0051] Example 1

[0052] Please see Figures 1-7 As shown, the quick-release belt proposed in this embodiment includes a front buckle plate 1, a belt 2, and a rear buckle plate 3. One end of the front buckle plate 1 is provided with a mounting groove 101, and a retaining hole 102 is provided on one side of the front buckle plate 1. The retaining hole 102 communicates with the mounting groove 101, and a screw 1021 is threaded into the retaining hole 102. Two retaining holes 102 are provided at equal intervals on one side of the front buckle plate 1. A screw 1021 is threaded into the retaining hole 102. By rotating the screw 1021 in the clockwise or counterclockwise direction, the depth to which the screw 1021 moves into the mounting groove 101 can be adjusted.

[0053] The mounting groove 101 is movably fitted onto one end of the waist belt 2, and one end of the screw 1021 is attached to the corresponding position on the side of the waist belt 2. The width and thickness of the waist belt 2 match the size of the mounting groove 101. By inserting one end of the waist belt 2 into the mounting groove 101 and rotating the nut of the screw 1021, the screw shank of the screw 1021 gradually moves into the mounting groove 101 and is tightly attached to the corresponding position on the side of the waist belt 2, thereby fixing the waist belt 2 to the front buckle plate 1.

[0054] The back of the front buckle plate 1 has a groove 103, and a connecting groove 106 is provided in the groove 103. A front magnetic block 107 is fixed in the connecting groove 106. The connecting groove 106 is located at the center of the groove 103. A front magnetic block 107 of matching size is installed in the connecting groove 106.

[0055] A rear buckle plate 3 is movably connected to the back of the front buckle plate 1. A second groove 301 is provided on the front side of the rear buckle plate 3. An installation frame 306 is provided in the second groove 301. A rear magnetic block 307 is fixed in the installation frame 306. The rear magnetic block 307 is opposite to the front magnetic block 107. The installation frame 306 is located at the center of the second groove 301. The rear magnetic block 307 of the same size is installed in the installation frame 306. When the front buckle plate 1 and the rear buckle plate 3 are closed, the front magnetic block 107 and the rear magnetic block 307 are opposite to each other and magnetically fixed.

[0056] Side plates 309 are arranged opposite each other on both sides of the back of the rear buckle plate 3. A guide plate 310 and a limiting plate 311 are fixed at both ends of the side plates 309 respectively. A locking mechanism 32 is movably connected in the limiting plate 311. The guide plate 310 is used to guide one end of the waist belt 2 through the back of the rear buckle plate 3 and between the guide plate 310, so that it can stably pass through the limiting plate 311 during continuous guiding and conveying, and be locked and fixed by the locking mechanism 32.

[0057] It should be further explained that one end of the waist belt 2 is movably sleeved between the rear buckle plate 3, the guide plate 310, and the limiting plate 311, while the locking mechanism 32 is used to adjust and fix the length of the waist belt 2.

[0058] The belt 2 has a movable steel plate 202 inside. The steel plate 202 is made of stainless steel and can be attracted and fixed by magnetic objects. The steel plate 202 also has a certain degree of flexibility and can be bent freely, so that it can be stably worn on the user's waist.

[0059] Furthermore, during the disassembly process, the flexible rebound force of the steel sheet 202 can be used to spring apart the separated front buckle plate 1 and rear buckle plate 3, thereby improving the belt disassembly speed.

[0060] The working principle of the quick-release waist belt proposed in this embodiment is as follows: When in use, one end of the waist belt 2 is inserted into the mounting groove 101, and a screw 1021 is inserted into the fixing hole 102. The screw 1021 is rotated so that the front end of the screw 1021 is close to the corresponding position on the side of the waist belt 2, thereby fixing one end of the waist belt 2 to the front buckle plate 1. At this time, the rear buckle plate 3 is fixed by mutual attraction of magnets on the rear side of the front buckle plate 1. Then, the other end of the waist belt 2 is passed through the rear side of the rear buckle plate 3 between the guide plate 310 and the limiting plate 311 and tightened to a suitable tightness. At this time, it is fixed by the locking mechanism 32. When quickly disassembling, the front buckle plate 1 and the rear buckle plate 3 are pushed in opposite directions, so that the limiting slot 305 on the fixing button 304 separates from the limiting piece 105 and rises along the inclined section, so that the magnetic block is separated, and the disassembly is completed.

[0061] Example 2

[0062] Please see Figures 1-7 As shown, the quick-release belt proposed in this embodiment, based on the first embodiment, further includes a slanted section 100 on the front buckle plate 1, located at one end of the groove 103.

[0063] An inclined section 302 is provided on the rear buckle plate 3, located at one end of the groove 301.

[0064] The opposite surfaces of inclined section 100 and inclined section 2 302 are set parallel to each other.

[0065] More specifically, when the front buckle 1 and the rear buckle 3 are closed, the first inclined section 100 and the second inclined section 302 are opposite to and fit together. When they are separated, the front buckle 1 separates from the rear buckle 3 by sliding along the inclined section. When they are joined together, the front buckle 1 joins the rear buckle 3 by sliding along the inclined section.

[0066] Furthermore, two sides of the groove 2 301 are provided with side strips 303 facing each other, and the two sides of the groove 1 103 are attached to the opposite outer side of the side strips 303.

[0067] More specifically, when the front buckle 1 and the rear buckle 3 are closed or separated, the edge strip 303 slides against the inside of the groove 103, thereby ensuring the stability of the sliding connection between the front buckle 1 and the rear buckle 3, so as to accurately align the front magnetic block 107 and the rear magnetic block 307.

[0068] Furthermore, a retaining groove 104 is provided at one end of the groove 103, the retaining groove 104 penetrates the surface of the front buckle plate 1, and a limiting piece 105 is provided at one end of the retaining groove 104.

[0069] A retaining button 304 is fixed at one end of the groove 301, and a limiting slot 305 is provided on the side of the retaining button 304.

[0070] The retaining button 304 is movably connected within the retaining slide 104, and the limiting slot 305 is engaged with the side of the limiting piece 105.

[0071] More specifically, when the front buckle plate 1 and the rear buckle plate 3 are separated and joined by sliding, the fixing button 304 slides in the fixing groove 104. When the limiting slot 305 is engaged with the side of the limiting piece 105, it plays the role of locking and fixing the front buckle plate 1 and the rear buckle plate 3 after they are joined.

[0072] It should be further explained that during the merging process, when the front buckle 1 and the rear buckle 3 slide down along the inclined section until their opposite surfaces are completely in contact, the retaining button 304 is placed in the retaining groove 104. As they continue to slide until the front magnetic block 107 and the rear magnetic block 307 are aligned and attracted, the limiting slot 305 on the side of the retaining button 304 engages with the side of the limiting piece 105. This prevents the buckle from separating due to the displacement of the magnetic blocks after the front buckle 1 and the rear buckle 3 are squeezed. This structural design ensures that when squeezed, the front buckle 1 and the rear buckle 3 move in opposite directions, making the engagement between the limiting slot 305 and the limiting piece 105 more tight.

[0073] During separation, the front buckle plate 1 and the rear buckle plate 3 are pushed in opposite directions and slid along the inclined section until the limiting slot 305 disengages from the limiting piece 105, thus separating the front buckle plate 1 from the rear buckle plate 3.

[0074] Furthermore, a protruding button 108 is provided at one end of the back of the front buckle plate 1, and a guide groove 308 is provided at one end of the rear buckle plate 3, which is located in the groove 301, and the protruding button 108 is movably connected in the guide groove 308.

[0075] More specifically, when the front buckle 1 and the rear buckle 3 are combined and separated, the protruding button 108 slides in the guide groove 308, which improves the stability of the connection between the buckles and avoids the phenomenon of shifting to the side.

[0076] Furthermore, the locking mechanism 32 includes a connecting rod 312 rotatably connected between the side plates 309, and a toothed buckle 315 is fixed on the side of the connecting rod 312.

[0077] The side of the belt 2 is provided with a strip groove 201, and the side of the buckle 315 is engaged with the side of the strip groove 201.

[0078] More specifically, when the connecting rod 312 rotates, it drives the side buckle 315 to rotate simultaneously. When the front end of the buckle 315 disengages from the corresponding strip groove 201 on the side of the waist belt 2, the waist belt 2 can be pushed and pulled freely to adjust the waist size bound by the waist belt 2. When the front end of the buckle 315 engages in the corresponding strip groove 201 on the side of the waist belt 2, it achieves the function of fixing the adjusted waist size.

[0079] Furthermore, torsion springs 314 are movably sleeved on the sides of both ends of the connecting rod 312, and the two ends of the torsion springs 314 are respectively fixed between the toothed buckle 315 and the side plate 309.

[0080] More specifically, the torsion spring 314 is used to reverse the twisting of the toothed buckle 315, so that the front end of the toothed buckle 315 remains engaged in the corresponding slot 201.

[0081] Furthermore, a button 313 is fixed to one end of the connecting rod 312, and the button 313 is attached to the side of the side plate 309.

[0082] More specifically, by turning the button 313, the connecting rod 312 drives the toothed buckle 315 to rotate, and the front end of the toothed buckle 315 disengages from the strip groove 201. At this time, the torsion spring 314 tightens. When the button 313 is released, the torque is released through the torsion spring 314, causing the connecting rod 312 to drive the toothed buckle 315 to rotate in the opposite direction, so that the toothed buckle 315 is engaged in the corresponding strip groove 201.

[0083] Example 3

[0084] The belt in this application has a steel plate inside, which increases the strength of the belt itself and allows different weights to be hung on the belt, such as water bottles, outdoor gear, protective equipment, etc., making it convenient for outdoor use.

[0085] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
