Description

Technical Field

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

[0002] Cable winding mechanisms are widely used in various electronic devices, household appliances, and industrial tools to neatly store and easily retrieve cables during use and storage. Existing cable winding mechanisms often employ spring-driven or manual operation, but these methods have significant drawbacks in practical applications. For example, traditional cable reels typically rely on mechanical latches for locking, which cannot achieve flexible locking at any position. This makes it difficult for users to freely control the cable length according to actual needs, often requiring repeated adjustments or forced pulling of the cable, which can easily lead to excessive stretching, wear, or even breakage. Furthermore, existing winding mechanisms have complex structures and unstable locking mechanisms, frequently resulting in accidental unlocking or locking, affecting safety and efficiency. Utility Model Content

[0003] In order to solve at least some of the problems existing in the prior art, this utility model provides a winding mechanism with a simple and stable structure, convenient cable winding, and the cable reel can be locked at any position.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cable winding mechanism includes a housing, within which a cable reel is rotatably connected. One side of the reel has a winding section for winding cables, and the other side of the reel, between it and the housing, has an elastic winding member that drives the reel to rotate along the cable winding direction. The edge of the reel has several circumferentially distributed limiting sections, and the housing contains a movable limiting component. This limiting component has a locked state (abutting against the limiting sections) and an unlocked state (separated from the limiting sections). In the unlocked state, the reel automatically rotates along the winding direction under the torque of the elastic winding member; in the locked state, the reel stops rotating.

[0005] By adopting the above technical solution: the reel provides automatic winding force through the elastic winding component, and the limiting component cooperates with the limiting part to achieve locking at any position, so that the cable length can be flexibly adjusted; at the same time, by switching between the locking and unlocking states, the winding process is ensured to be stable and reliable, avoiding cable loosening or excessive stretching, and improving the convenience and safety of use.

[0006] Preferably, the limiting component includes a limiting member and an elastic reset member. The limiting member is rotatably connected to the housing. The inner end of the limiting member has a limiting lug facing the limiting part, and the outer end of the limiting member has a lever. The elastic reset member drives the limiting lug to abut against the limiting part. In the natural state, the abutment between the limiting lug and the limiting part locks the coil. When the lever is pressed, the limiting component rotates by a preset angle, causing the limiting lug to separate from the limiting part, and the coil unlocks. By adopting the above technical solution, the limiting member automatically resets through the elastic reset member, achieving rapid locking and unlocking; at the same time, the linkage between the lever and the limiting lug simplifies the operation process, ensures a stable locking state, and prevents accidental contact or unlocking.

[0007] Preferably, a button is provided on the housing corresponding to the lever, the button being slidably connected to the housing, and the lever abutting against the inner end of the button; when the button is pressed, the coil is in the unlocked state, and when the button is released, the coil is in the locked state. By adopting the above technical solution, button operation is more convenient, and users can control the locking state with simple pressing.

[0008] Preferably, the inner side of the button is provided with several connecting posts, and the outer side of the housing is provided with a cavity for accommodating the button. The bottom surface of the cavity is provided with a connecting hole corresponding to the connecting post, and the connecting post slides through the connecting hole. The button has latches on both sides, and the bottom of the cavity corresponding to the latch is provided with an avoidance hole, through which the latch slides. By adopting the above technical solution, the connecting posts and latches ensure the button is securely installed and prevent it from falling off; at the same time, the sliding connection design guides the button's movement, ensuring smoother button movement and preventing jamming.

[0009] Preferably, the limiting part is configured as a ratchet, and the limiting lug is configured as a pawl; in the natural state, the pawl abuts against the ratchet, causing the coil to be unidirectionally locked in the winding direction; when the pawl rotates to separate from the ratchet, the coil is released from locking. By adopting the above technical solution, the meshing structure of the ratchet and pawl provides a reliable unidirectional locking function, allowing the cable to be pulled out freely, but preventing it from being freely wound up after being pulled out, thereby flexibly adjusting the cable length and further improving the convenience of operation.

[0010] Preferably, a cover plate is provided on the outer side of the winding section, and a winding limiting groove for positioning the cable is provided between the cover plate and the spool. By adopting the above technical solution, the cover plate and the winding limiting groove guide the cable to wind up in an orderly manner, ensuring that the cable is wound neatly, preventing tangling or deviation, and thus reducing wear and malfunctions.

[0011] Preferably, the inner wall of the housing is provided with a rotating shaft, and the center of the turntable has a shaft hole for rotatable connection with the rotating shaft. The elastic winding component is configured as a coil spring, which is sleeved on the rotating shaft. One end of the coil spring is connected to the rotating shaft, and the other end of the coil spring is connected to the turntable. By adopting the above technical solution, the rotating shaft and the coil spring provide stable torque output, driving the coil to automatically wind up; at the same time, the precise fit between the shaft hole and the rotating shaft reduces rotational friction, ensuring a smooth and efficient winding process.

[0012] Preferably, the inner wall of the housing has an outer ring, and the turntable has an inner ring on the side facing the outer ring. The coil spring is disposed within the inner ring, and the outer ring is fitted onto the inner ring to form a clearance fit. By adopting the above technical solution, the outer and inner rings form a protective structure, which on the one hand prevents the coil spring from shifting or being damaged, and on the other hand provides a relatively enclosed space for the coil spring, reducing the influence of external impurities, moisture, etc. on the coil spring and improving the stability of the coil spring.

[0013] Therefore, this utility model has the following beneficial effects: (1) By cooperating with the limiting component and the limiting part, the spool can be reliably locked at any position, meeting the user's need to flexibly adjust the cable length; (2) The elastic winding component drives the spool to automatically wind up, simplifying the operation steps and improving the winding efficiency and convenience; (3) The coordinated design of the button and the limiting component ensures a fast response in the locking and unlocking process, improving the user experience.

Detailed Implementation

[0021] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0022] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0023] like Figures 1-6 The cable winding mechanism shown includes a housing 1, within which a cable reel 2 is rotatably connected. One side of the reel 2 has a winding section 21 for winding the cable, and the other side of the reel 2, between it and the housing 1, has an elastic winding member 3 that drives the reel 2 to rotate along the cable winding direction. The edge of the reel 2 has several circumferentially distributed limiting sections 22. A movable limiting component 4 is located within the housing 1, having a locked state (abutting against the limiting sections 22) and an unlocked state (separated from the limiting sections 22). In the unlocked state, the reel 2 automatically rotates along the winding direction under the torque of the elastic winding member 3; in the locked state, the reel 2 stops rotating. In this structure, the limiting component 4 cooperates with the limiting sections 22, allowing the reel 2 to be locked at any rotational position, enabling the user to flexibly control the cable length as needed. Simultaneously, the elastic winding member 3 provides automatic winding force, ensuring the cable automatically retracts after use, preventing tangling and improving convenience and efficiency.

[0024] In some embodiments, such as Figure 2 and Figure 4 As shown, a cover plate 211 is provided on the outer side of the winding section 21, and a winding limiting groove 212 for positioning the cable winding is provided between the cover plate 211 and the cable reel 2. The cover plate 211 protects the cable from external damage, and at the same time guides the cable to wind up in an orderly manner through the winding limiting groove 212, preventing tangling and knotting, extending the service life of the cable, and ensuring a smooth winding process.

[0025] A rotating shaft 13 is provided on the inner wall of the housing 1. A shaft hole 23 is provided at the center of the reel 2, which is rotatably connected to the rotating shaft 13. The elastic winding member 3 is configured as a coil spring 31, which is sleeved on the rotating shaft 13. One end of the coil spring 31 is connected to the rotating shaft 13, and the other end of the coil spring 31 is connected to the reel 2. The rotating shaft 13 and the shaft hole 23 provide stable rotational support and reduce wear; at the same time, the coil spring 31 stores and releases energy to drive the reel 2 to automatically wind the cable, ensuring uniform and lasting winding force.

[0026] like Figure 5 and Figure 6 As shown, the limiting component 4 includes a limiting member 41 and an elastic reset member 42. The limiting member 41 is rotatably connected to the housing 1. The inner end of the limiting member 41 is provided with a limiting lug 411 facing the limiting part 22, and the outer end of the limiting member 41 is provided with a lever 412. The elastic reset member 42 drives the limiting lug 411 to abut against the limiting part 22. In the natural state, the limiting lug 411 abuts against the limiting part 22, locking the coil 2. When the lever 412 is pressed, the limiting component 4 rotates by a preset angle, causing the limiting lug 411 to separate from the limiting part 22, and the coil 2 is unlocked. In this embodiment, the elastic reset member 42 is a torsion spring.

[0027] To further improve the ease of rotation of the limiting component, in some embodiments, such as Figure 2 As shown, a button 11 is provided on the housing 1 corresponding to the lug 412. The button 11 is slidably connected to the housing 1, and the lug 412 abuts against the inner end of the button 11. When the button 11 is pressed, the coil 2 is in the unlocked state; when the button 11 is released, the coil 2 is in the locked state. Several connecting posts 111 are provided on the inner side of the button 11, and a cavity 12 for accommodating the button 11 is provided on the outer side of the housing 1. The bottom surface of the cavity 12 is provided with connecting holes 121 corresponding to the connecting posts 111, and the connecting posts 111 slide through the connecting holes 121. Buckles 112 are provided on both sides of the button 11, and clearance holes 122 are provided at the bottom of the cavity 12 corresponding to the buckles 112, allowing the buckles 112 to slide through the clearance holes 122. Integrating the button 11 onto the surface of the housing 1, and with the button slidably guided by the connecting posts and connecting holes, ensures smooth button pressing, prevents tilting, and prevents jamming. Users can quickly unlock the button by pressing it, and it automatically resets and locks after being released by a torsion spring, making it very convenient to use.

[0028] like Figure 5As shown, the limiting part 22 is configured as a ratchet 221, and the limiting lug 411 is configured as a pawl 413. In the natural state, the pawl 413 abuts against the ratchet 221, causing the coil 2 to be unidirectionally locked in the winding direction. When the pawl 413 rotates to separate from the ratchet 221, the coil 2 is released from locking. The unidirectional locking is achieved by the cooperation of the ratchet 221 and the pawl 413, allowing the coil to rotate freely in the winding direction but preventing reverse rotation. At the same time, the even distribution of the ratchet ensures that the coil can be locked at any position, meeting the user's precise control requirements for cable length.

[0029] like Figure 4 As shown, in some embodiments, an outer ring 14 is provided on the inner wall of the housing 1, and an inner ring 24 is provided on the side of the coil 2 facing the outer ring 14. The coil spring 31 is disposed inside the inner ring 24, and the outer ring 14 is sleeved on the inner ring 24 to form a clearance fit. The outer ring 14 and the inner ring 24 form a protective layer to prevent dust and impurities from entering the area of ​​the coil spring 31; at the same time, the clearance fit ensures that the coil 2 rotates flexibly without jamming, improving the reliability of the mechanism.

[0030] Referring to the accompanying drawings, the working principle of this invention is as follows: When cable 5 needs to be pulled out, due to the unidirectional limiting of the pawl 413 and ratchet 221, the user can directly pull the cable to any length. When the pawl 413 and ratchet 221 are released, they automatically lock and limit the cable, preventing the reel from rotating along the winding direction. When the cable needs to be wound up, button 11 is pressed. Pressing the button causes the limiting member 41 to rotate through the lug, separating the limiting lug 411 (pawl 413) from the limiting part 22 (ratchet 221). At this time, the reel 2 is unlocked, and the cable is automatically wound up under the torque of the elastic winding member 3 (coil spring 31), winding the entire cable into the winding limiting groove 212. This winding mechanism has a stable overall structure, and the reel can be locked at any position, allowing the cable to be positioned at any length. Pressing the button automatically winds up the cable, making it very convenient to use.

[0031] In the description of this invention, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solutions of this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting this invention.

[0032] Although specific embodiments of the invention have been described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications can be conceived without departing from the spirit and scope of the invention.
