[0002] A power bank, also known as a portable charger, is a portable power source that can charge mobile devices such as smartphones and tablets. It stores electrical energy through an internal rechargeable battery and outputs current via a USB port or its own charging cable. Power banks have solved the problem of insufficient battery power for mobile devices when there are no power outlets available.

[0003] The power bank comes with a built-in charging cable, allowing users to charge it directly. The charging cable has a cable clip; the charging head snaps into a slot on the clip to secure it, creating a carrying strap for easy portability or storage.

[0004] Currently, the charging cable retainer has an opening on the side facing away from the power bank casing to ensure the charging head fits properly into the slot. However, with this type of retainer, the charging head is prone to detaching from the slot, especially when the retainer is made of plastic, this problem is more pronounced. Utility Model Content

[0005] This utility model provides a lanyard structure and a power bank to solve the problem that the card holder head is easy to detach from the card slot, especially when the card holder is made of plastic, this problem is more prominent.

[0006] This utility model discloses a hanging rope structure, including a rope body and a wire clamping device. One end of the rope body is used to be installed on the outer shell of the object being set, and the other end is provided with a clamping head. The wire clamping device is installed on the rope body and has a wire clamping cavity. Taking the outer shell of the object being set as a reference, the side of the wire clamping device facing away from the outer shell is the outer side, and the side of the wire clamping device adjacent to the outer side is the adjacent side. The wire clamping cavity has an upper opening on the top surface of the wire clamping device and a lower opening on the bottom surface. The wire clamping cavity has an inlet opening on the adjacent side, which connects the upper opening and the lower opening. The rope body is inserted into the wire clamping cavity from the inlet opening, and the clamping head is clamped in the wire clamping cavity to form a hanging rope structure.

[0007] Optionally, one side of the inlet opening is provided with a first protruding edge protruding towards the other side, the first protruding edge blocking the side of the locking head.

[0008] Optionally, a second protrusion protrudes in the direction of the first protrusion and the second protrusion blocks the side of the locking head.

[0009] Optionally, the lower opening edge is provided with a tapering flange, which supports the tail end of the locking head.

[0010] Optionally, the size of the upper opening is larger than the size of the lower opening.

[0011] Optionally, the cable clip has a threading hole extending from the top to the bottom, and a fixing sleeve is installed in the threading hole, with the rope being fixedly threaded through the fixing sleeve.

[0012] Optionally, the outer layer of the rope is a woven outer layer.

[0013] Optionally, the rope is a charging cable and the locking head is a charging head; and / or, when the locking head is locked in the opening of the cable, the head end of the locking head does not protrude from the top surface.

[0014] Optionally, on the wire clamping component, the wire threading hole is located close to the housing, and the wire clamping cavity is located away from the housing relative to the wire threading hole.

[0015] This utility model also discloses a portable power supply, including a housing and the aforementioned lanyard structure; the lanyard is a charging cable, and the clip is a charging head for the charging cable; one end of the charging cable is installed on the housing, and the charging head is disposed on the other end of the charging cable and is used to plug into an external charging object to charge the charging object.

[0016] The beneficial effects of the hanging rope structure provided in this embodiment are as follows: the hanging rope structure of this utility model has an inlet side opening on the adjacent side of the hanging rope clamping cavity. The rope is inserted into the hanging rope clamping cavity through the inlet side opening, thereby locking the clamping head in the hanging rope clamping cavity. When used as a lifting rope structure, when the hanging rope clamping cavity is pulled by external force, the clamping head mainly forms resistance with the side of the outer side of the hanging rope clamping component and the opposite side. The inlet side opening is located on the adjacent side, which is different from the force position of the clamping head. Therefore, the clamping head is not easy to detach from the hanging rope clamping cavity or the inlet side opening. Even when the hanging rope clamping component is made of plastic, the clamping head is not easy to detach from the hanging rope clamping cavity. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] This utility model embodiment provides a hanging rope structure, such as Figures 1 to 6 As shown, the hanging rope structure includes a rope body 2 and a wire clamping component 3. One end of the rope body 2 is used to install on the outer shell 1 of the object being set, and the other end is provided with a clamping head 21; the wire clamping component 3 is installed on the rope body 2, and the wire clamping component 3 has a wire clamping cavity 31. Taking the outer shell 1 of the object being set as a reference, the side of the wire clamping component 3 facing away from the outer shell 1 is the outer side surface 32, and the side of the wire clamping component 3 adjacent to the outer side surface 32 is the adjacent side surface 33. The wire clamping cavity 31 opens at the top surface 34 of the wire clamping component 3 to form an upper opening 311, and opens at the bottom surface 35 of the wire clamping component 3 to form a lower opening 312; the wire clamping cavity 31 opens at the adjacent side surface 33 to form a wire inlet side opening 313, and the wire inlet side opening 313 connects the upper opening 311 and the lower opening 312. The rope 2 is inserted into the wire clamping cavity 31 from the wire inlet 313, and the clamping head 21 is clamped in the wire clamping cavity 31 so that the rope 2 forms a hanging rope structure.

[0022] The cable clamping cavity 31 of the present invention has an inlet side opening 313 on the adjacent side 33. The rope 2 is inserted into the cable clamping cavity 31 through the inlet side opening 313, thereby locking the clamping head 21 in the cable clamping cavity 31. When used as a lifting rope structure, when the cable clamping cavity 31 is pulled by external force, the clamping head 21 mainly forms a resistance with the side of the outer side 32 of the cable clamping component 3 and the opposite side. The inlet side opening 313 is located on the adjacent side 33, and the force position is different from that of the clamping head 21. The clamping head 21 is not easy to detach from the cable clamping cavity 31 or the inlet side opening 313. Even when the cable clamping component 3 is a plastic part, the clamping head 21 is not easy to detach from the cable clamping cavity 31.

[0023] The aforementioned installation target is a device with an application of a lanyard structure. For example, if the lanyard structure is applied to a power bank, then the installation target is the power bank itself, and the outer casing is the power bank's outer shell. Of course, the lanyard structure of this invention can also be applied to other suitable devices, and this invention does not impose any specific limitations.

[0024] In contrast, taking a power bank as an example, the slot of the current cable clip 3 has an opening on the side away from the power bank housing (i.e., the outer side 32 mentioned above), thus ensuring that the charging head 21 can be properly inserted into the slot. However, with this cable clip 3, when the charging cable 2 is used as a lanyard, the point of force applied to the charging head 21 coincides with the opening on the slot, making it easy for the charging head 21 to be pulled out unexpectedly from the opening. This problem is even more pronounced when the cable clip 3 is made of plastic, as plastic parts are more prone to deformation.

[0025] Specifically, in this utility model, the rope body 2 of the hanging structure is inserted into the cable clamping cavity 31 through the cable inlet side opening 313. Then, pulling the rope body 2 causes the clamping head 21 to be clamped into the cable clamping cavity 31 through the upper opening 311, thus forming a hanging structure for easy carrying or hanging. When using the rope body 2, the clamping head 21 is pushed out from the cable clamping cavity 31 through the upper opening 311, and the rope body 2 is removed from the cable inlet side opening 313. The rope body 2 can then be detached from the cable clamping component 3 for normal charging.

[0026] Combination Figure 1 and Figure 2 As shown, the side of the cable clip 3 facing away from the outer casing 1 is the outer side 32, and the side adjacent to the outer side 32 is the adjacent side 33. In this state, the top surface 34 and the bottom surface 35 of the cable clip 3 are two opposing surfaces. At this time, the bottom surface 35 faces the placement platform of the lanyard structure, and the top surface 34 faces away from the placement platform of the lanyard structure. The end of the rope 2 opposite to the clip head 21 is introduced into the interior of the outer casing 1 and electrically connected to the necessary circuit board of the lanyard structure. The specific implementation can adopt conventional technology in the art, which will not be described in detail here. The lanyard structure also includes necessary lithium batteries, charging interfaces such as Type-C interfaces, switches, etc. The specific implementation can adopt conventional technology in the art, which will not be described in detail here. The outer casing 1 can be assembled from multiple sub-casings according to specific needs. The specific implementation can adopt conventional technology in the art, which will not be described in detail here. The cable clip 3 can be a plastic part.

[0027] Furthermore, a first protruding edge 36 protruding towards the other side is provided on one side of the wire inlet opening, and the first protruding edge 36 abuts against the side of the locking head 21. The first protruding edge 36 on one side of the wire inlet opening, protruding towards the other side, can abut against the side of the locking head 21, which can effectively limit the lateral displacement of the locking head 21 within the wire clamping member 3, prevent it from sliding out of the wire inlet opening due to lateral external force, enhance the fixing effect of the wire clamping member 3 on the locking head 21, and improve the stability of the rope 2 when used as a hanging rope.

[0028] Furthermore, a second protruding edge 37 is provided on the other side of the wire inlet opening, protruding towards the first protruding edge 36. The second protruding edge 37 provides resistance to the side of the locking head 21. A second protruding edge 37 is also provided on the other side of the wire inlet opening, protruding towards the first protruding edge 36, further enhancing the resistance to the side of the locking head 21. The locking head 21 is limited on both sides by the first protruding edge 36 and the second protruding edge 37 respectively, making it more stable within the wire clamping cavity 31, significantly improving the reliability of the rope 2 as a hanging rope, and reducing the risk of use due to the locking head 21 falling off.

[0029] Specifically, the lower opening 312 has a tapering flange 38 along its edge, which supports the tail end 211 of the locking head 21. The edge of the lower opening 312 is one of the main stress-bearing positions when the rope 2 is used as a hanging rope structure. The tapering flange 38 along the lower opening 312 supports the tail end 211 of the locking head 21, providing support for the locking head 21 from below and preventing it from falling out of the wire clamping cavity 31. This improves the all-round limiting of the locking head 21, further reduces the probability of the locking head 21 accidentally falling out of the wire clamping component 3, and ensures the stability of the hanging rope structure when used as a hanging rope.

[0030] More specifically, the opening size of the upper opening 311 is larger than the opening size of the lower opening 312.

[0031] The upper opening 311 is larger than the lower opening 312, making it easier to insert and remove the locking head 21. When inserted, the larger upper opening 311 allows the locking head 21 to easily enter the cable clamping cavity 31; after locking, the smaller lower opening 312, together with the tapered protrusion 38, can tightly support the tail end 211 of the locking head 21, enhancing the fixing effect, while making the rope 2 more compact when used as a hanging rope.

[0032] The cable clamp 3 has a threading hole 39 extending from the top surface 34 to the bottom surface 35. A fixing sleeve 310 is installed in the threading hole 39, and the rope 2 is fixedly threaded through the fixing sleeve 310. The cable clamp 3 has a threading hole 39 and a fixing sleeve 310, through which the rope 2 is fixedly threaded. The fixing sleeve 310 enhances the connection strength between the rope 2 and the cable clamp 3, preventing the rope 2 from slipping or loosening from the cable clamp 3 during use, ensuring that the rope 2 will not fall off when it is used as a hanging rope to bear tension, and improving the safety and stability of the hanging rope structure. The fixing sleeve 310 can be a rubber sleeve, silicone sleeve, etc. The fixing sleeve 310 can be glued to the threading hole 39.

[0033] The outer layer of rope 2 is a braided outer layer. This braided outer layer increases the strength, abrasion resistance, and tensile strength of rope 2. When rope 2 is frequently bent, pulled, or rubbed against other objects, the braided outer layer effectively reduces the risk of damage, extends its service life, enhances its appearance and texture, and allows it to withstand greater tensile force when used as a hanging rope, making it less prone to breakage.

[0034] Specifically, the rope body 2 is the charging cable, and the clip head 21 is the charging head. The charging head can be a Type-C charging head, which has advantages such as strong universality, good compatibility, fast transmission speed, and support for reversible insertion. Using a Type-C interface can easily connect to most electronic devices, meet different charging needs, and facilitate users to charge different devices in scenarios such as when they are out and about, thus improving the practicality of the lanyard structure.

[0035] When the locking head 21 is engaged in the cable clamping cavity 31, its head end 212 does not protrude from the top surface 34. This ensures the overall appearance of the lanyard structure remains flat and aesthetically pleasing. Simultaneously, it prevents the protruding part of the locking head 21 from colliding or scratching with other objects during carrying or placement, reducing the risk of damage to the locking head 21.

[0036] Furthermore, on the cable clamping component 3, the threading hole 39 is located close to the housing, while the cable clamping cavity 31 is located away from the housing relative to the threading hole 39. This arrangement of the threading hole 39 being close to the outer housing 1 and the cable clamping cavity 31 being away from the outer housing 1 facilitates the rational allocation of space in the cable clamping component 3, ensuring that the rope 2 will not adversely affect the structural strength of the cable clamping component 3 during insertion and fixation. It also facilitates the installation and operation of the rope 2, allowing the clamping head 21 to smoothly engage with the cable clamping cavity 31 and form a hanging rope structure. This ensures that the rope 2 is both securely fixed and easily detached from the cable clamping component 3 when charging is required.

[0037] like Figures 1 to 6As shown, this utility model also discloses a portable power bank, including a housing 1 and the aforementioned lanyard structure; the lanyard 2 is a charging cable, and the charging head is a charging head for the 21-pin charging cable; one end of the charging cable is mounted on the housing 1, and the charging head is disposed on the other end of the charging cable 1 and is used to plug into an external charging object to charge the object, such as charging a mobile phone. Since this portable power bank has the aforementioned lanyard structure, it also possesses the technical effects and specific structure related to the aforementioned lanyard structure, which will not be elaborated upon here.

[0038] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
