Description

Technical Field

[0001] This utility model relates to the field of tool accessories technology, and in particular to a rope hanging device. Background Technology

[0002] One end of the lanyard device is attached to the user's body or clothing, such as hanging one end on the user's wrist or attaching it to a keychain on clothing, while the other end is attached to an item, such as a mobile phone or a tool, to provide functions such as preventing items from being lost and freeing up the hands for other operations.

[0003] However, existing lanyard devices have some shortcomings. First, lanyard devices generally have a reel-in mechanism for automatic reel-in; however, this also means that the phone or other item is constantly under the pull of the reel-in mechanism, making operation inconvenient. Furthermore, a fastener is usually used between the lanyard device and the item, requiring the item to be released by unfastening it; however, the current fastener release process is rather cumbersome, and its convenience needs improvement.

Detailed Implementation

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1-16 As shown, this embodiment provides a hanging rope device 1, including a hook assembly 2, a locking assembly 3, and a rope 4. The hook assembly 2 has a winding mechanism inside. The rope 4 has a first end and a second end. The first end of the rope 4 is wound inside the hook assembly 2, and the second end of the rope 4 is a free end. The second end of the rope 4 is connected to the locking assembly 3, which is connected to the user's item 5. Figure 3The image shows the locking assembly 3 connected to the user's mobile phone 5, but it is not limited to this. The lanyard device 1 of this embodiment can also be used in outdoor activities, such as mountaineering, skiing, and fishing. The lanyard device 1 can be hung on the body or bag to suspend small items that are easily accessible, such as keys, knives, and pliers, improving convenience. When the rope 4 is fully wound, the locking assembly 3 can lock the free end of the rope 4 to the hook assembly 2, preventing the free end of the rope 4 from coming loose and causing the item 5 to fall, thus allowing for safer use of the lanyard device 1.

[0022] See Figures 1-3 The hook assembly 2 includes a first housing 21 and a second housing 26, which are assembled to form a complete housing 20, and an inner cavity is formed in the housing 20. The hook assembly 2 also includes a hook portion 22, a coil spring 23, a winding reel 24, and a swing block 25. The hook portion 22 is connected to the housing 20, or, in some other embodiments, the hook portion 22 may be integrally formed with the housing 20 or a part of the housing 20.

[0023] The coil spring 23, the winding reel 24, and the oscillating block 25 are installed inside the housing 20. (See also...) Figure 4 The winding reel 24 includes a reel surface 241 and a sidewall 242 extending vertically from the reel surface 241. A central hole 2411 is provided at the center of the reel surface 241. A central post 211 protrudes inward from the first housing 21. The central hole 2411 and the central post 211 are pivotally engaged, allowing the winding reel 24 to be rotatably disposed within the inner cavity of the housing 20. The reel surface 241 and the sidewall 242 enclose an open mounting space 243. A coil spring 23 is installed in the mounting space 243, with one end connected to a slot 2111 on the central post 211 and the other end connected to the sidewall 242 of the winding reel 24. The rope 4 is wound around the outer periphery of the winding reel 24, and the coil spring 23 provides a winding force for winding the rope 4; Figure 7 As shown, the elastic force of the coil spring 23 causes the winding reel 24 to rotate along the first direction A, thereby winding the rope 4 into the reel 24. In this embodiment, the first direction A is clockwise.

[0024] See Figure 5 and Figure 6The second housing 26 has an inner surface 261 facing the winding reel 24, and a pivot shaft 262 protrudes from the inner surface 261. The swing block 25 includes a swing block body 251, which has a pivot hole 253. The pivot shaft 262 pivotally engages with the pivot hole 253, thereby allowing the swing block 25 to be mounted on the inner surface 261 of the second housing 26 in a swingable manner. The swing block body 251 also has a protruding post 252. The protruding post 252 and the pivot hole 253 are spaced apart from each other on the swing block body 251. For example, the protruding post 252 and the pivot hole 253 are located at different ends of the swing block body 251, so that the protruding post 252 can pivot and swing around the pivot shaft 262 with the swing block 25. Figure 6 As indicated by the middle arrow S, the protrusion 252 extends from the swing block body 251 toward the winding reel 24, and the protrusion 252 is substantially perpendicular to the reel surface 241.

[0025] Further reading Figure 6 The inner surface 261 of the second housing 26 is also provided with a groove 263, and the swing block 25 is fitted and limited in the groove 263, thereby limiting the swing angle range of the swing block 25 and making the swing block 25 more stable.

[0026] See Figure 7 and Figure 8 The winding reel 24 has an outer track groove 51 and an inner track groove 52 recessed on its surface 241. The outer track groove 51 surrounds the inner track groove 52. The reel surface 241 also has a first connecting groove 53 and a second connecting groove 54 that connect the outer track groove 51 and the inner track groove 52. Thus, an annular boss 61 with a notch is formed between the outer track groove 51 and the inner track groove 52, and a guide boss 62 is provided in the notch of the annular boss 61. The annular boss 61 has a first end 611 and a second end 612. The first connecting groove 53 is located between the first end 611 and the guide boss 62, and the second connecting groove 54 is located between the second end 612 and the guide boss 62.

[0027] The protruding post 252 extends into the interior of one of the outer track groove 51, the inner track groove 52, the first connecting groove 53, or the second connecting groove 54 and can slide therein. The pivoting swing of the swing block 25 works in coordination with the rotation of the winding disc 24, so that the protruding post 252 slides and switches between the outer track groove 51, the inner track groove 52, the first connecting groove 53, or the second connecting groove 54, as will be described later.

[0028] The guide boss 62 has a pointed end facing the first end 611, which protrudes outward. The first side of the pointed end forms part of the sidewall of the inner track groove 52. The second side 621 of the pointed end is inclined. The distance between the end of the second side 621 facing the center and the rotation center of the disk surface 241 is less than the distance between the inner side of the first end 611 and the rotation center of the disk surface 241. The second side 621 also serves as one sidewall of the first connecting groove 53, thus the first connecting groove 53 is also inclined. The inclination direction of the first connecting groove 53 is from the inside out and generally inclined along the first direction A. Here, "from the inside out" refers to the direction from the rotation center of the disk surface 241 to the edge of the disk surface 241. The first connecting groove 53 is used to guide the protrusion 252 from the inner track groove 52 into the outer track groove 51, such as... Figure 9 As shown.

[0029] See Figure 8 A central boss 63 is formed on the disk surface 241, and an inner track groove 52 surrounds the outer periphery of the central boss 63, that is, the inner track groove 52 is located between the central boss 63 and the annular boss 61. The central boss 63 is provided with a guide protrusion 631, which is close to the opening of the first connecting groove 53. The guide protrusion 631 can push the protrusion 252 away from the center of the disk surface 241, so that the protrusion 252 can enter the first connecting groove 53 more easily from the inner track groove 52.

[0030] See Figure 8 The guide boss 62 has a concave structure 622 at one end facing the second end 612, which serves as the first sidewall of the second connecting groove 54. The second sidewall of the second connecting groove 54 is the second guide surface 613 of the second end 612. The opening of the concave structure 622 faces the first direction A. The concave structure 622 has a first guide surface 623 on the side facing the outer track groove 51. The distance between the end of the first guide surface 623 facing the outer track groove 51 and the rotation center of the disk surface 241 is greater than the distance between the outer side of the second end 612 and the rotation center of the disk surface 241. The first guide surface 623 is used to guide the protrusion 252 from the outer track groove 51 into the second connecting groove 54, and the protrusion 252 can be received in the concave structure 622. Figure 10 As shown. The second guide surface 613 is used to guide the protrusion 252 in the concave structure 622 from the second connecting groove 54 into the inner track groove 52, as shown. Figure 8 As shown.

[0031] See Figure 7 ,definition Figure 7The initial state is when the central protruding post 252 is received in the concave structure 622. In the initial state, since the opening of the concave structure 622 faces the first direction A, and the elastic force of the coil spring 23 causes the winding disc 24 to tend to rotate along the first direction A, the concave structure 622 is limited by the protruding post 252, thus limiting the winding disc 24. The rotation of the winding disc 24 along the first direction A is locked. That is, in the initial state, the protruding post 252 is received in the concave structure 622, and the rotation of the winding disc 24 along the first direction A is locked.

[0032] Further reading Figure 8 From the initial state, when the rope 4 is pulled outward along the W direction, the winding reel 24 rotates along a second direction B, which is opposite to the first direction A. In this embodiment, the second direction B is counterclockwise. The second guide surface 613 is inclined, and the inclination direction of the second guide surface 613 is from the inside out and generally inclined along the second direction B. Here, "from the inside out" means from the rotation center of the reel surface 241 to the edge of the reel surface 241. Under the guidance of the second guide surface 613, the protruding post 252 in the concave structure 622 is guided to enter the inner track groove 52 via the second connecting groove 54. At this time, further refer to Figure 9 If rope 4 continues to be pulled outward in the W direction, the protrusion 252, after being pushed by the guide protrusion 631, enters the first connecting groove 53 and is guided into the outer track groove 51. As rope 4 is continuously pulled out, the protrusion 252 continuously circulates in the outer track groove 51; this is the rope 4 pulling operation. When rope 4 is pulled out to a suitable length, pulling rope 4 can be stopped and rope 4 can be released. Further details can be found at this point. Figure 10 The spring force of the coil spring 23 causes the winding reel 24 to rotate along the first direction A. Under the action of the coil spring 23, the rope 4 is wound up a small length along the N direction. The protrusion 252 is guided by the outer track groove 51 into the second connecting groove 54 under the action of the first guide surface 623 and is received in the concave structure 622. At this time, the rotation of the winding reel 24 along the first direction A is locked, thus completing the pulling-out operation of the rope 4. Since the rotation of the winding reel 24 along the first direction A is locked, the rope 4 pulled out to a certain length can basically maintain the length pulled out. The rope 4 can be locked, so the item 5 connected to the rope 4 will not be affected by continuous tension, making the operation more convenient.

[0033] See Figure 11When you want to retract rope 4, pull rope 4 outward a short distance (about 2 cm). The winding reel 24 rotates in the second direction B. Under the guidance of the second guide surface 613, the protrusion 252 in the concave structure 622 is guided through the second connecting groove 54 into the inner track groove 52. Since rope 4 is only pulled a short distance, the protrusion 252 remains in the inner track groove 52 and will not enter the outer track groove 51 through the first connecting groove 53. Since rope 4 is released after being pulled outward a short distance, see further... Figure 12 After the rope 4 is released, the elastic force of the coil spring 23 causes the winding disc 24 to rotate in the first direction A. The protrusion 252 continuously circulates in the inner track groove 52, and under the continuous action of the elastic force of the coil spring 23, the rope 4 is completely wound up. This is the rope 4 retraction operation.

[0034] Furthermore, during the retraction of rope 4, when it is desired that rope 4 stop retracting at a certain length, it is only necessary to pull rope 4 out a further length and then release it. The length of rope 4 pulled out allows the protrusion 252 to enter the outer track groove 51 from the inner track groove 52 via the first connecting groove 53. After rope 4 is released, the elasticity of the coil spring 23 causes the winding reel 24 to rotate along the first direction A. The protrusion 252 is guided by the first guide surface 623 and received by the concave structure 622. The rotation of the winding reel 24 along the first direction A is locked, thereby partially winding rope 4. That is, rope 4 can also be operated and locked during the retraction process. In summary, the rope hanging device 1 of this embodiment can achieve automatic locking during both pulling out and retraction of rope 4. Specifically, the rope 4 of the rope hanging device 1 can be pulled out to adjust the length of rope 4. After the rope 4 is pulled out, the rope hanging device 1 will automatically lock at certain intervals of pulled-out length, which greatly facilitates operation. Moreover, the item 5 connected to the rope 4 will not be continuously affected by the tension, resulting in higher comfort. To retract the rope, simply pull rope 4 out a short length (about 2 cm) and release it; rope 4 will then retract automatically.

[0035] See Figure 3 , Figures 13-15 When the rope 4 is fully retracted, the locking assembly 3 locks the free end of the rope 4 to the hook assembly 2, preventing the free end of the rope 4 from coming off. This ensures that the rope 4 is locked after retraction, and the item 5 is secured to the rope hanging device 1, preventing it from falling off easily, thus allowing for safer use of the rope hanging device 1. The locking assembly 3 includes a base 31 and a pull buckle 32, with the base 31 connected to the hook assembly 2; see further details. Figure 6A latching structure 27 is provided at the cable outlet of the housing 20 of the hook assembly 2. A latching connector 315, T-shaped, is provided on the top of the base 31 and can engage with the latching structure 27, thereby connecting the base 31 to the hook assembly 2. The base 31 has a cable passage hole 314 through which the free end of the rope 4 passes and connects to the pull buckle 32. The pull buckle 32 has a wiring hole 376 through which the free end of the rope 4 connects to the pull buckle 32. The pull buckle 32 includes a buckle ring 377 for connecting to the item 5. The pull buckle 32 and the base 31 can engage or disengage, thereby locking or separating the free end of the rope 4 from the hook assembly 2.

[0036] The base 31 includes a downwardly opening cavity structure with an inner cavity 312. A first magnet 311 is mounted on the top surface of the inner cavity 312. The sidewall of the inner cavity 312 has multiple channels 313, which are evenly distributed along the circumference of the base 31. Ball bearings 33 are slidably installed in the channels 313. In this embodiment, three channels 313 are shown. The buckle 32 includes an outer sleeve 34, a retaining ring 35, a spring 36, and a central post 37. The central post 37 is connected to a buckle ring 377. The outer sleeve 34 is displaceably fitted over the central post 37. In this embodiment, the middle region of the inner wall of the outer sleeve 34 has an annular protrusion 341, and the lower part of the central post 37 has a shoulder 371. The two ends of the spring 36 abut against the shoulder 371 and the annular protrusion 341, respectively, so that the outer sleeve 34 is subjected to an upward elastic force relative to the central post 37. The central column 37 is provided with a retaining ring groove 373, which is used to install the retaining ring 35. The upper end of the annular protrusion 341 can abut against the retaining ring 35, thereby limiting the outer sleeve 34.

[0037] The upper end of the central post 37 is provided with a second magnetic attractor 375. The second magnetic attractor 375 can be a magnet or a metal that can be attracted by the first magnet 311, such as iron. The second magnetic attractor 375 can also be integrated with the central post 37. The central post 37 is also provided with a snap-fit ​​groove 372 above the retaining ring groove 373.

[0038] The diameter of the ball 33 is larger than the wall thickness of the inner cavity 312 of the base, so that at least a portion of the ball 33 protrudes from the side wall of the inner cavity 312 of the base. This "at least a portion of the ball 33 protruding from the side wall of the inner cavity 312 of the base" includes both cases where a portion of the ball 33 protrudes inwards or outwards from the side wall of the inner cavity 312 of the base. The upper end of the outer sleeve 34 can be fitted onto the outer peripheral surface of the base 31, and the upper end of the outer sleeve 34 can cover the center position of the channel 313, thereby limiting the movement of the ball 33.

[0039] See Figure 14In this configuration, the latching assembly 3 is in a locked state. The ball bearing 33 is limited by the upper end of the outer sleeve 34 and moves inward to engage with the locking groove 372, thereby locking the base 31 and the pull buckle 32. The elastic force of the spring 36 keeps the latching assembly 3 in the locked state. Furthermore, the first magnet 311 and the second magnetic attractant 375 attract each other, further maintaining the locked state of the latching assembly 3.

[0040] When the latch assembly 3 is to be unlocked, the outer sleeve 34 is pulled downwards. The outer sleeve 34 moves downwards against the elastic force of the spring 36, and the upper end of the outer sleeve 34 separates from the channel 313. The ball 33 is no longer limited by the upper end of the outer sleeve 34. The downward pulling force on the outer sleeve 34 is transmitted to the central post 37 via the spring 36. Under the action of the downward pulling force, the edge of the locking groove 372 of the central post 37 pushes the ball 33 outwards. The ball 33 is pushed and at least partially exits the inner cavity 312 of the base, so that the central post 37 can be pulled out of the inner cavity 312 of the base. At this time, the downward pulling force also overcomes the attraction between the first magnet 311 and the second magnetic attractor 375. The unlocking pull direction of the outer sleeve 34 of the buckle assembly 3 is the same as the direction in which the buckle 32 separates from the base 31. The unlocking operation can be achieved with a single pull, which can be completed with one hand, unlike traditional buckles that require two hands. When the rope 4 needs to be pulled out, the buckle assembly can be easily pulled out with a simple unlocking operation, which greatly improves the convenience of use.

[0041] Furthermore, the channel 313 has a tapered structure, with its diameter gradually decreasing towards the inner cavity 312 of the base. Thus, the channel 313 has a minimum diameter towards the inner cavity 312 of the base and a maximum diameter away from the inner cavity 312. The diameter of the ball 33 is between the maximum and minimum diameters of the channel 313. The ball 33 is made of ferromagnetic material and can be attracted by the first magnet 311, thereby keeping the ball 33 within the channel 313 and preventing it from falling out, making assembly more convenient.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
