Description

Technical Field

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

[0002] In daily life and outdoor settings, cable locks are widely used as a convenient protective tool for locking bags, temporarily securing bicycles and scooters, and other items. However, existing cable locks have gradually revealed many significant shortcomings in practical use, failing to meet users' needs for efficient, convenient, and secure protection.

[0003] Currently, traditional cable locks have a relatively simple structural design, mostly consisting of a separate cable and lock, often as separate units. This design necessitates manual organization and storage of the cable when not in use, which is not only cumbersome but also prone to tangling and knotting, significantly impacting ease of use in the future. Furthermore, adjusting the cable length using traditional cable locks often requires tedious steps, such as manual knotting or the use of additional fasteners. This is not only time-consuming and labor-intensive but also makes it difficult to accurately control the effective usable cable length, failing to flexibly adapt to the protection needs of different scenarios.

[0004] Furthermore, some cable retractable locks currently on the market generally have small cable diameters (usually only around 3mm). While this makes them easy to wind and store, they have weak shear resistance and are easily damaged by ordinary cutting tools, resulting in a low level of anti-theft protection and failing to meet the high security needs of outdoor use (such as theft prevention for valuables like bicycles and electric scooters). Simply increasing the cable diameter to improve strength can lead to increased cable rigidity, making winding difficult and causing problems like tangled winding and jamming, thus affecting the user experience.

[0005] Therefore, this utility model provides a novel cable telescopic lock to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a cable telescopic lock. This cable telescopic lock, through the cooperation of the locking tongue, combination lock and locking buckle assembly, can quickly fix and release the cable length, meeting the user's flexible needs for different lengths. Moreover, the combination lock design improves the anti-theft performance of the device. It can only be unlocked through correct operation, effectively preventing the cable from being accidentally operated or maliciously pulled.

[0007] This utility model adopts the following technical solution: a cable telescopic lock, comprising:

[0008] case;

[0009] A winding device is disposed within the receiving cavity of the housing, comprising a support shaft fixedly installed within the housing, a winding wheel sleeved on the support shaft, an energy storage device disposed between the support shaft and the winding wheel, and a cable wound on the winding wheel; one end of the energy storage device is fixedly connected to the support shaft, and the other end is fixedly connected to the winding wheel; one end of the cable is fixedly connected to the winding wheel, and the other end is provided with a locking tongue;

[0010] A locking device is disposed within the housing and includes a latch assembly that engages with the latch, and a combination lock that drives the latch assembly to open and close.

[0011] Furthermore, the outer wall surface of the latch is provided with an annular groove, which is used to form a snap-fit ​​with the latch assembly to achieve locking or unlocking of the latch.

[0012] Furthermore, the locking assembly includes a base, a slider slidably mounted on the base, and a reset elastic member disposed between the slider and the base; one end of the reset elastic member is connected to the slider, and the other end is connected to the base;

[0013] The slider has a limiting groove and an unlocking groove communicating with the limiting groove; the outline of the limiting groove matches the annular groove so as to fix the locking tongue through a snap-fit ​​engagement.

[0014] The slider has a locked position and an unlocked position; the reset elastic element can drive the slider to reset to the locked position.

[0015] Furthermore, when the reset elastic element drives the slider to reset to the locked position, the annular groove of the locking tongue engages with the limiting groove of the slider, thereby achieving locking and fixing between the locking tongue and the slider;

[0016] When the slider is in the unlocked position, the annular groove of the latch disengages from the limiting groove and enters the unlocking groove, thus unlocking the latch from the slider.

[0017] Furthermore, the limiting groove of the slider has a first guide slope formed on the end face near the locking tongue insertion side;

[0018] The insertion end of the locking tongue is provided with a second guide slope, the angle of which is complementary to that of the first guide slope.

[0019] Furthermore, the combination lock includes a lock body and a lever, the lock body being driven to the lever to push the slider to the unlock position.

[0020] Furthermore, the lever has a first inclined surface at one end near the slider, the slider has a boss on the side opposite to the lever, and the boss has a second inclined surface on the side facing the lever that matches the first inclined surface.

[0021] Furthermore, the winding wheel includes a wheel body and a double-sided baffle wheel sleeve, and the double-sided baffle wheel sleeve is snapped into connection with the wheel body;

[0022] The double-sided baffle wheel sleeve includes a wheel sleeve and baffles disposed on both sides of the wheel sleeve. The baffles are integrally formed with the wheel sleeve, and the outer diameter of the baffles is larger than the maximum diameter of the cable winding layer on the winding wheel.

[0023] Furthermore, the outer diameter of the wheel sleeve is 10 cm to 35 cm;

[0024] The diameter of the cable is 5mm to 12mm.

[0025] Furthermore, the energy storage component is a torsion spring, one end of which is snapped into the support shaft and the other end is snapped into the wheel body.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1) The general working principle of the cable telescopic lock in this utility model:

[0028] When the cable is needed, the user pulls the cable end with the locking tongue outward, causing the cable to rotate around the support shaft. At this time, the energy storage device between the support shaft and the winding wheel is twisted and stores energy. As the cable continues to be pulled out, the winding wheel continues to rotate and maintain energy storage until the cable reaches the required length.

[0029] Once the cable is pulled out to the target length, insert the locking tongue into the locking assembly to form a mechanical engagement. At this point, the locking tongue is fixed, and the cable cannot be pulled back by the rebound force of the energy storage component, thus locking the cable length.

[0030] When it is necessary to retrieve the cable, the combination lock is operated correctly (such as entering the correct password, turning the key, etc.) to open the latch assembly and release the constraint on the bolt. At this time, the energy storage device releases the stored elastic potential energy, causing the winding wheel to rotate in the opposite direction, automatically winding the cable back onto the winding wheel, completing the retrieval.

[0031] The cable retractable lock of this invention integrates the cable, support shaft, winding wheel, and energy storage device into a single unit, housed together with the locking device within the casing, thus reducing the overall size of the device to some extent. Simultaneously, utilizing the elastic potential energy of the energy storage device, the cable can be automatically retracted and wound after unlocking, eliminating the need for manual handling, simplifying the operation process, and improving efficiency. Furthermore, the cooperation of the locking tongue, combination lock, and latch assembly allows for quick fixing and release of the cable length, meeting users' flexible needs for different lengths. The combination lock design enhances the device's anti-theft performance; unlocking is only possible through correct operation (such as entering a password or using a key), effectively preventing accidental or malicious pulling of the cable.

[0032] 2) The cable diameter in the cable telescopic lock of this application can be made from 5mm to 12mm. Cables from 5mm to 12mm (especially metal cables) require specialized heavy-duty cutting tools to break, significantly improving the lock's anti-theft level and enhancing its protection of locked items. Furthermore, by simultaneously increasing the outer diameter of the wheel sleeve, a larger bending radius is provided for thicker cables. With an increased outer diameter, the bending curvature of the cable during winding decreases, allowing harder cables to conform more smoothly to the wheel sleeve surface, reducing frictional resistance caused by forced bending and preventing jamming during stretching or retraction.

[0043] The technical solutions of 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 some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The present invention will be described in detail with reference to specific embodiments:

[0045] like Figures 1 to 6 As shown, this utility model provides a cable telescopic lock, which can be used in various scenarios such as bag locking and outdoor protection (e.g., bicycle and scooter protection), and includes:

[0046] Housing 1; In this embodiment, the housing 1 consists of an upper housing 10 and a lower housing 11, which are detachably connected by fasteners, which not only ensures the sealing and stability of the overall structure, but also facilitates the assembly, inspection and maintenance of the internal winding device 2 and locking device 3; the fasteners can be bolts, screws, etc.

[0047] A winding device 2 is disposed within the receiving cavity of the housing 1, and includes a support shaft 20 fixedly installed within the housing 1, a winding wheel 21 sleeved on the support shaft 20, an energy storage element 22 disposed between the support shaft 20 and the winding wheel 21, and a cable 23 wound on the winding wheel 21; one end of the energy storage element 22 is fixedly connected to the support shaft 20, and the other end is fixedly connected to the winding wheel 21; one end of the cable 23 is fixedly connected to the winding wheel 21, and the other end is provided with a locking tongue 24;

[0048] Locking device 3, which is disposed in the housing 1, includes a latch assembly 30 that cooperates with the latch 24, and a combination lock 31 that drives the latch assembly 30 to open and close.

[0049] The general working principle of the cable telescopic lock in this utility model is as follows:

[0050] When the cable is needed, the user pulls the end of the cable 23 with the locking tongue 24 outward, causing the cable 23 to drive the winding wheel 21 to rotate around the support shaft 20. At this time, the energy storage element 22 between the support shaft 20 and the winding wheel 21 is twisted and stores energy. As the cable 23 is continuously pulled out, the winding wheel 21 continues to rotate and maintains energy storage until the cable 23 reaches the required length.

[0051] Once the cable 23 is pulled out to the target length, the locking tongue 24 is inserted into the locking assembly 30, forming a mechanical engagement. At this point, the locking tongue 24 is fixed, and the cable 23 cannot be pulled back by the rebound force of the energy storage component 22, thus locking the cable length.

[0052] When the cable needs to be retrieved, the locking assembly 30 is opened by correctly operating the combination lock 31 (such as entering the correct password, turning the key, etc.), releasing the constraint on the locking tongue 24. At this time, the energy storage component 22 releases the stored elastic potential energy, driving the winding wheel 21 to rotate in the opposite direction, automatically winding the cable 23 back onto the winding wheel 21, completing the storage.

[0053] In this utility model, the cable retractable lock integrates the cable 23, support shaft 20, winding wheel 21, and energy storage device 22 into one unit, which, together with the locking device 3, is built into the housing 1, thus reducing the overall size of the device to a certain extent. Simultaneously, utilizing the elastic potential energy of the energy storage device 22, the cable 23 can automatically retract and wind itself after unlocking, eliminating the need for manual handling, simplifying the operation process, and improving efficiency. Furthermore, through the cooperation of the locking tongue, combination lock 31, and latch assembly 30, the cable length can be quickly fixed and released, meeting the flexible needs of users for different lengths. The design of the combination lock 31 enhances the anti-theft performance of the device; it can only be unlocked through correct operation (such as entering a password or using a key), effectively preventing accidental or malicious pulling of the cable.

[0054] Furthermore, in some specific embodiments, the winding wheel 21 includes a wheel body 211 and a double-sided baffle wheel sleeve 212, the double-sided baffle wheel sleeve 212 being snapped into connection with the wheel body 211.

[0055] Specifically, one end of the wheel body 211 may be provided with a plurality of slots 2111 spaced apart along its circumference;

[0056] The double-sided baffle wheel sleeve 212 is provided with a snap-fit ​​protrusion 2121 that matches the snap-fit ​​groove 2111. The snap-fit ​​protrusion 2121 is placed in the snap-fit ​​groove 2111 to realize the snap-fit ​​connection between the double-sided baffle wheel sleeve 212 and the wheel body 211. It should be noted that in this utility model, the position and number of the snap-fit ​​groove 2111 are not limited, and can be selected by those skilled in the art according to the actual situation.

[0057] The circumferentially spaced slots 2111 of the wheel body 211 and the engaging protrusions 2121 of the double-sided baffle wheel sleeve 212 form a multi-point interlocking structure, which can evenly distribute stress circumferentially. During the rotation of the winding wheel 21 (especially under the torque of cable stretching or retraction), this multi-contact interlocking method can effectively prevent relative slippage between the wheel body 211 and the double-sided baffle wheel sleeve 212, ensuring synchronous rotation and avoiding transmission loss or structural noise caused by loose connection. In addition, the circumferentially spaced slots 2111 and engaging protrusions 2121 form a mutually restraining radial locking force after assembly, which, combined with the rotational inertia of the winding wheel 21 during operation, can further enhance the anti-loosening effect of the connection. Compared with a single snap-fit ​​structure, the multi-point distribution can avoid overall connection failure due to local wear and extend the product's service life.

[0058] More specifically, the double-sided baffle wheel sleeve 212 includes a wheel sleeve 2122 and baffles 2123 disposed on both sides of the wheel sleeve 2122. The baffles 2123 are integrally formed with the wheel sleeve 2122; and the outer diameter of the baffles 2123 is larger than the maximum diameter of the cable winding layer on the winding wheel 21.

[0059] The outer diameter of the baffle 2123 is larger than the maximum diameter of the cable winding layer on the winding wheel 21, so that the baffle 2123 is always higher than the outer edge of the cable winding layer, whether the cable is fully retracted (thickest winding) or partially pulled out (thinner winding). This can effectively prevent the cable 23 from axial movement caused by vibration, tension fluctuation or accidental contact, fundamentally avoiding the risk of the cable 23 falling off the winding wheel 21 and ensuring the safety of equipment operation.

[0060] More specifically, in this embodiment, the outer diameter of the wheel sleeve 2122 is 10CM to 35CM;

[0061] The diameter of the cable 23 is 5mm to 12mm. In existing cable telescopic locks, the diameter of the cable 23 is generally only about 3mm. Existing cables of about 3mm are too thin and can be easily cut by cutting tools (such as wire cutters). However, the diameter of the cable 23 in the cable telescopic lock of this application can be made to be 5mm to 12mm. Cables of 5mm to 12mm (especially those made of metal) require special heavy-duty cutting tools to break, which greatly improves the anti-theft level of the lock and enhances the protection of the locked items.

[0062] It should be noted that thin cables of about 3mm are relatively flexible and easy to bend and fit into the winding wheel during the winding process, making winding easier. However, cables of 5mm to 12mm have significantly increased rigidity due to their larger diameter. If the outer diameter of the wheel sleeve 2122, which is compatible with thin cables, is used, the bending radius may be too small, resulting in increased winding resistance. This may even lead to problems such as the cable not fitting into the wheel sleeve 2122 and irregular winding (such as lifting or stacking), affecting the smoothness of stretching and retraction.

[0063] Therefore, this application increases the outer diameter of the sleeve 2122 simultaneously to provide a larger bending radius for the thicker cable 23. With the increased outer diameter of the sleeve 2122, the bending curvature of the cable during winding decreases, and the stiffer cable 23 can fit more smoothly against the surface of the sleeve 2122, reducing frictional resistance caused by forced bending and avoiding jamming during stretching or retraction.

[0064] Specifically, in this embodiment, the energy storage element 22 is a torsion spring. As an energy storage element, the torsion spring works by storing elastic potential energy through torsional deformation. When released, it generates a stable reverse torque, which is exactly matched with the rotational driving force required by the winding wheel 21 when retrieving the cable.

[0065] One end of the torsion spring is snapped into the support shaft 20, and the other end is snapped into the wheel 211. No additional fasteners (such as screws or clips) are required; positioning and fixation are achieved solely through elastic deformation during assembly, significantly simplifying the assembly process of the winding device and reducing production time and costs. It should be noted that this invention does not specifically limit how the snap-fit ​​connection between the torsion spring and the support shaft 20, as well as the wheel 211, is implemented; such design can be created by those skilled in the art based on actual conditions.

[0066] Furthermore, in some specific embodiments, the outer wall surface of the latch 24 is provided with an annular groove 241, which is used to form a snap-fit ​​with the latch assembly 30 to realize the locking and fixing or unlocking of the latch 24.

[0067] Specifically, the locking assembly 30 includes a base 301, a slider 302 slidably mounted on the base 301, and a reset elastic member 303 disposed between the slider 302 and the base; one end of the reset elastic member 303 is connected to the slider 302, and the other end is connected to the base 301.

[0068] The slider 302 has a limiting groove 3021 and an unlocking groove 3022 communicating with the limiting groove 3021; ​​the outline of the limiting groove 3021 matches the annular groove 241 so as to fix the locking tongue 24 by snap-fit.

[0069] The slider 302 has a locked position and an unlocked position, and the reset elastic element 303 can drive the slider 302 to reset to the locked position.

[0070] More specifically, when the reset elastic element 303 drives the slider 302 to reset to the locked position, the annular groove 241 of the locking tongue 24 engages with the limiting groove 3021 of the slider 302, thereby locking and fixing the locking tongue 24 and the slider 302.

[0071] When the slider 302 is in the unlocked position, the annular groove 241 of the latch 24 disengages from the limiting groove 3021 and enters the unlocking groove 3022, thus unlocking the latch 24 and the slider 302.

[0072] When the cable is pulled out to the required length, the locking tongue 24 moves with the cable and inserts into the working position of the locking assembly 30. At this time, the slider 302 is in the locked position under the elastic force of the reset elastic element 303. The limiting groove 3021 of the slider 302 engages with the annular groove 241 of the locking tongue 24, forming an axial constraint. The locking tongue 24 cannot move axially, thus locking the cable length.

[0073] Next, when the combination lock 31 drives the slider 302 to slide to the unlocked position against the elastic force of the reset elastic element 303, the limiting groove 3021 disengages from the annular groove 241, and the annular groove 241 of the latch 24 enters the unlocking groove 3022 of the slider 302. Since the unlocking groove 3022 does not have axial constraint on the annular groove 241, the latch 24 can move axially, realizing the retraction of the cable 23.

[0074] Finally, when the combination lock 31 releases the driving force on the slider 302, the reset elastic element 303 releases its elastic force, pushing the slider 302 to automatically reset from the unlocked position to the locked position, waiting for the next locking operation.

[0075] The slider 302 switches between locking and unlocking by sliding, and with the automatic reset function of the reset elastic element 303, the operation stroke is short and the response is fast. When the combination lock 31 is unlocked, the slider 302 can instantly switch to the unlocked position to avoid delays in cable 23 retraction due to structural jamming; and after the combination lock 31 is released, the slider 302 can immediately reset to the locked position to ensure immediate locking capability for the next use. At the same time, the contour matching design of the annular groove 241 and the limiting groove 3021 forms a surface contact engagement, which can evenly distribute the axial tensile force on the locking tongue 24, especially the large tension brought by the 5MM to 12MM thick cable.

[0076] More specifically, the limiting groove 3021 of the slider 302 has a first guide slope 3021-1 formed on the end face near the insertion side of the locking tongue 24;

[0077] The insertion end of the locking tongue 24 is provided with a second guide slope 242, the angle of which is complementary to the first guide slope 3021-1.

[0078] During the insertion of the latch 24 into the latch assembly 30, the guide ramps of both achieve force transmission and direction conversion through ramp contact:

[0079] When the latch 24 extends along with the cable and moves toward the locking assembly 30, the second guide slope 242 at the insertion end of the latch 24 will first contact the first guide slope 3021-1 of the limiting groove 3021 of the slider 302. Since the inclination angles of the two slopes are complementary (i.e., the sum of the slope angles is about 90°), the axial thrust of the latch 24 will be decomposed into a normal force perpendicular to the slope through the slope, and then converted into a component force that drives the slider 302 to slide laterally. This component force overcomes the elastic force of the reset elastic element 303, pushing the slider 302 temporarily away from the locking position, making way for the insertion of the latch 24.

[0080] When the locking tongue 24 is fully inserted into the annular groove 241 and aligned with the limiting groove 3021, the slider 302 is reset under the action of the reset elastic element 303, and the limiting groove 3021 engages with the annular groove 241 to complete the locking.

[0081] More specifically, the combination lock 31 includes a lock body 311 and a lever 312. The lock body 311 and the lever 312 are drivenly connected, driving the lever 312 to push the slider 302 to the unlock position. In this utility model, the lock body 311 can be a combination lock cylinder or a key lock cylinder, etc., and is not specifically limited in this utility model. In this embodiment, the lock body 311 is a combination lock cylinder.

[0082] Meanwhile, a first inclined surface 3121 is provided at one end of the lever 312 near the slider 302, a boss 304 is provided on the side of the slider 302 opposite to the lever 312, and a second inclined surface 3041 matching the first inclined surface 3121 is provided on the side of the boss 304 facing the lever 312.

[0083] When the user correctly operates the combination lock 311 (such as entering the correct password or turning the key), the lock body 311 drives the lever 312 to move linearly, causing the first inclined surface 3121 of the lever to gradually approach the second inclined surface 3041 of the boss 304 of the slider 302. The first inclined surface 3121 pushes the second inclined surface 3041 to overcome the elastic force of the reset elastic element 303 in the latch assembly 30, pushing the slider 302 from the locked position to the unlocked position until the limiting groove 3021 of the slider 302 disengages from the annular groove 241 of the latch 24, the latch 24 is released, and the cable 23 is automatically retracted under the action of the energy storage element 22.

[0084] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
