Description

Technical Field

[0001] This utility model relates to the field of clothing accessories technology, and in particular to an adjustable clothing accessory. Background Technology

[0002] Clothing accessories, such as waist chains, strap buckles, or decorative connectors, are indispensable elements in clothing coordination. They not only serve an aesthetic purpose but also often fulfill practical functions such as tightening garments and securing them. To accommodate different body types and the needs of styling clothing of varying thicknesses, these accessories typically require a degree of length adjustment.

[0003] However, most existing adjustable clothing accessories use traditional pinhole buckles, D-rings, or simple spring-fed friction clips to achieve length adjustment. The adjustment precision of pinhole buckles is limited by the hole spacing, making precise fine adjustments impossible and often resulting in the garment being too tight or too loose. While stepless adjustment structures relying on friction or spring force solve the precision problem, during vigorous exercise or large movements, the tension at both ends of the accessory can easily overcome internal friction, leading to unexpected length changes or even loosening. They also lack reliable mechanical self-locking functions, cannot maintain the set length for extended periods, and the adjustment process often lacks guidance, making it prone to jamming or wobbling, thus affecting the user experience.

[0004] Therefore, this utility model proposes an adjustable clothing accessory to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the technology of adjustable clothing accessories, such as limited adjustment precision, easy length change or even loosening due to force during the wearer's vigorous exercise, and low reliability due to lack of reliable mechanical self-locking function, this utility model aims to provide an adjustable clothing accessory with improved structure that can effectively solve the above problems.

[0006] This utility model provides an adjustable clothing accessory, including: a housing, a decorative body fixedly connected to the top of the housing, an adjustment component disposed inside the housing, and a connecting component disposed at the end of the adjustment component; as well as a tube shell, a drive rod, a worm gear, a two-way lead screw, a worm wheel, a connecting rod, and a knob.

[0007] The adjusting assembly has a precision transmission structure that includes a worm gear transmission pair and a bidirectional lead screw.

[0008] Furthermore, the tubular shell is fixedly connected to both sides of the housing, and the drive rod is slidably connected inside the tubular shell; the adjustment assembly includes the worm gear and the double-acting lead screw rotatably connected inside the housing, the worm wheel is fixedly connected to the middle of the double-acting lead screw, and the worm wheel meshes with the worm gear; one end of the drive rod extending into the housing is threadedly connected to the double-acting lead screw, and the other end of the drive rod away from the double-acting lead screw extends to the outside of the tubular shell and is connected to the connecting assembly; one end of the worm gear is fixedly connected to the connecting rod, and the other end of the connecting rod away from the worm gear extends to the outside of the housing and is fixedly connected to the knob; by rotating the knob, the worm gear is driven to rotate, which in turn drives the double-acting lead screw to rotate, thereby causing the two drive rods to move in opposite directions or in reverse along the tubular shell, thereby achieving length adjustment.

[0009] Preferably, two mounting blocks are fixedly connected inside the housing, and the worm gear is rotatably connected between the two mounting blocks to ensure the stability of the worm gear rotation and limit its axial displacement.

[0010] Preferably, two mounting plates are fixedly connected inside the housing, and the two ends of the bidirectional lead screw are rotatably connected inside the two mounting plates, so that the mounting plates provide stable axial support and positioning for the bidirectional lead screw.

[0011] Preferably, a sliding groove is formed inside the tube shell, and a sliding rod is fixedly connected to the outside of the drive rod. The sliding rod is slidably connected inside the sliding groove. The cooperation between the sliding rod and the sliding groove restricts the drive rod from rotating with the bidirectional lead screw, thus ensuring linear drive efficiency.

[0012] Preferably, a limiting block is fixedly connected to the drive rod. The limiting block is used to restrict the movement position of the drive rod, prevent it from falling off when adjusted to the limit position, and ensure structural safety.

[0013] Preferably, the connecting assembly includes a housing and a limiting plate, the limiting plate being fixedly connected to one end of the drive rod extending to the outside of the housing, and the housing being sleeved on the outside of the limiting plate.

[0014] Preferably, the limiting plate is rotatably connected inside the housing, allowing the housing to rotate relative to the drive rod, thereby preventing torque or knotting at the connection point.

[0015] Preferably, a hanging ring is fixedly connected to the outer shell, which is used to connect with clothing and provide a convenient hanging point.

[0016] Preferably, the decorative element is a detachable and replaceable structure, which can be changed according to preference to meet the user's personalized wearing and matching needs in different occasions.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a transmission structure of knob-driven worm gear and worm wheel in conjunction with bidirectional lead screw, utilizes the mechanical self-locking characteristics of the worm gear and worm wheel and the synchronous driving capability of the bidirectional lead screw to solve the problems of low adjustment precision and easy loosening and slippage of existing clothing accessories during wearing and exercise. It achieves the technical effect of precise and controllable adjustment length and stable and anti-loosening after fixing.

[0018] 2. This utility model solves the problem of the drive rod easily getting stuck due to rotation or lateral deviation during the screw drive process by setting a sliding groove inside the tube shell and setting a sliding rod on the drive rod.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides an adjustable clothing accessory, which aims to solve the structural defects of existing clothing accessories, such as insufficient length adjustment accuracy and the tendency to loosen or slip off due to force during wearing after adjustment.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustable clothing accessory includes a housing 1 and a decorative body 2 fixedly connected to the top of the housing 1. The housing 1 serves as the core mounting base of the entire device, providing support and protection space for the internal mechanical structure. The decorative body 2 is used to enhance the overall aesthetics of the accessory and serves a decorative function. The decorative body 2 adopts a detachable and replaceable structural design, allowing users to replace the decorative body 2 according to personal preferences or different clothing styles, thereby enhancing the diversity and personalized experience of the product.

[0026] The housing 1 is equipped with an adjustment component 3, which constitutes the core drive and transmission system of this device and is used to realize the length extension and retraction adjustment function. The outer walls on both sides of the housing 1 are respectively fixedly connected with tube shells 309. The tube shells 309 extend outward along the transverse axis of the housing 1, and play a role in guiding support and dust protection. The end of the adjustment component 3 extends through the tube shells 309 to the outside and is provided with a connecting component 4. The connecting component 4 serves as a terminal interface for hanging with external clothing. It can move closer to or away from the housing 1 under the drive of the adjustment component 3, thereby changing the length of the overall accessory. The adjustment component 3 includes a knob 301 set on the outside of the housing 1 and a transmission mechanism located inside the housing 1. The knob 301 serves as the power input end, allowing the user to control the operation of the internal mechanism by manual rotation.

[0027] To solve the above-mentioned technical problems, the adjustable clothing accessory also includes a worm gear transmission mechanism with a two-way lead screw structure, and the transmission mechanism forms a specific linkage and connection relationship with the aforementioned knob 301 and drive rod 310.

[0028] Please refer to the following carefully. Figure 3 The core structure will be described in detail below: A connecting rod 302 is fixedly connected to the side of the knob 301 facing the housing 1. The end of the connecting rod 302 away from the knob 301 extends through the side wall of the housing 1 and is fixedly connected to one end of the worm 303. Two mounting blocks 307 are fixedly connected to the bottom surface inside the housing 1. The worm 303 is rotatably connected between the two mounting blocks 307. The mounting blocks 307 limit the axial displacement of the worm 303 and support its smooth rotation. Two mounting plates 306 are fixedly connected inside the housing 1 and above the worm 303. The two ends of the bidirectional lead screw 305 are rotatably connected inside the two mounting plates 306. A worm wheel 304 is fixedly connected to the middle of the bidirectional lead screw 305. The worm wheel 304 meshes with the worm 303 below to form a worm wheel and worm gear speed reduction and torque increase transmission pair. This transmission pair has mechanical self-locking characteristics and can automatically lock the angle position of the bidirectional lead screw 305 when the adjustment stops to prevent the length from changing unexpectedly due to external tension.

[0029] Meanwhile, one end of the drive rod 310 extending into the housing 1 is threadedly connected to the bidirectional lead screw 305. Since the two ends of the bidirectional lead screw 305 are provided with threads of opposite directions, when the worm gear 304 drives the bidirectional lead screw 305 to rotate, the thread engagement causes the two drive rods 310 connected to the two ends of the bidirectional lead screw 305 to move synchronously towards each other or away from each other along the axial direction, thereby realizing the shrinking or stretching of the overall length of the clothing accessories. As for the power source for rotating the drive knob 301, this embodiment adopts a manual operation method, relying on human power to twist the knob 301 to provide input torque, which is simple and intuitive.

[0030] Based on the above embodiments, to ensure the motion stability and straightness of the drive rod 310 and prevent it from spinning freely along with the bidirectional lead screw 305, please refer to... Figure 4 The inner wall of the tube shell 309 is provided with a sliding groove 308 extending along the length direction. The drive rod 310 is located inside the tube shell 309 and is fixedly connected to a sliding rod 311. The sliding rod 311 is slidably connected inside the sliding groove 308. The sliding rod 311 and the sliding groove 308 form an anti-rotation guide fit, forcing the drive rod 310 to only reciprocate linearly along the axis of the tube shell 309. To prevent the drive rod 310 from falling off during the outward extension process, a limiting block 312 is fixedly connected to the outer surface of the drive rod 310. The limiting block 312 is located between the threaded connection between the drive rod 310 and the bidirectional lead screw 305 and the inner end face of the tube shell 309. When the limiting block 312 moves to the end position of the tube shell 309, it is blocked, thereby limiting the movement limit position of the drive rod 310.

[0031] Regarding the end connection structure, the connection component 4 includes a housing 401 and a limiting plate 403. The limiting plate 403 is fixedly connected to one end of the drive rod 310 extending to the outside of the tube housing 309. The housing 401 is sleeved on the outside of the limiting plate 403. The limiting plate 403 is rotatably connected in the cavity inside the housing 401, and the geometric dimensions of the limiting plate 403 are larger than the opening diameter of the housing 401 to prevent it from falling out. A hanging ring 402 is fixedly connected to the side of the housing 401 away from the drive rod 310. The hanging ring 402 is used to hang with clothing. This rotatable connection structure allows the hanging ring 402 to rotate freely relative to the drive rod 310, avoiding wrinkles in clothing or uneven force on accessories due to deadlock at the connection point during wearing or adjustment.

[0032] The working principle of this adjustable clothing accessory is as follows: In use, the decorative body 2 on the top of the shell 1 can be replaced according to personal preference or clothing style. The hanging rings 402 on the connecting components 4 on both sides can be attached to the corresponding positions of the clothing. When it is necessary to adjust the length of the clothing accessories, the knob 301 can be manually turned. The knob 301 drives the worm gear 303 to rotate between the mounting blocks 307 through the connecting rod 302. The worm gear 303 drives the worm wheel 304 that is meshed with it to rotate. The worm wheel 304 drives the bidirectional lead screw 305 to rotate synchronously inside the mounting plate 306.

[0033] Since the drive rod 310 is threaded to the end of the double-acting screw 305, and the slide rod 311 fixedly connected to the drive rod 310 is guided and restricted by the slide groove 308 inside the tube shell 309, the drive rod 310 cannot rotate with the double-acting screw 305. Therefore, the rotation of the double-acting screw 305 will be converted into the linear movement of the drive rod 310 along the axial direction of the tube shell 309, so that the two drive rods 310 simultaneously retract inward or extend outward, realizing precise adjustment of the overall length of the accessory. The limit block 312 plays a role in preventing it from falling off when adjusted to the limit position.

[0034] After adjustment, the length is kept fixed by the self-locking characteristic of the meshing transmission between the worm gear 304 and the worm 303, without the need for additional locking operation. During the wearing process, the outer shell 401 rotates freely relative to the drive rod 310 through the internal limiting plate 403, which drives the hanging ring 402 to adapt to the body movement and the shape of the clothing, preventing torque or dead knots from being generated at the connection.

[0035] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
