Description

Technical Field

[0001] This utility model relates to the field of mobile power bank technology, and in particular to a structure for preventing loosening of the connection port of a mobile power bank. Background Technology

[0002] Portable power banks, as portable charging devices, have become indispensable items in people's daily lives and work. When using a power bank to charge electronic devices or transmit data, the electronic device needs to be connected to the power bank's port via a plug. However, existing power bank ports typically rely solely on the plug's insertion and removal mechanism for connection. When subjected to external impacts, vibrations, or pulling, the plug can easily detach from the port, leading to charging interruptions or data transmission failures, causing inconvenience to users.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the connection port of existing power banks usually only relies on the plug itself to achieve connection. When subjected to external force collision, vibration or pulling, the plug is easy to come loose from the connection port, resulting in charging interruption. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, the connection port of a power bank usually only relies on the plug itself to achieve connection. When subjected to external force collision, vibration or pulling, the plug is easy to come loose from the connection port, resulting in charging interruption. To this end, we propose a power bank connection port anti-loosening structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a mobile power bank connection port anti-loosening structure, comprising a mobile power bank body: an input terminal is provided on the side wall of the mobile power bank body, two output terminals are provided on the bottom of the mobile power bank body, a display screen and a switch are electrically connected to the surface of the mobile power bank body, two sliding chambers are fixedly connected to the bottom of the mobile power bank body, a U-shaped plate is slidably connected to the inner wall of the sliding chamber, two springs are fixedly connected to one side of the U-shaped plate, the other end of the springs is fixedly connected to the inner wall of the sliding chamber, and two support plates are fixedly connected to the bottom of the mobile power bank body.

Detailed Implementation

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figure 1-4 As shown, this utility model provides a technical solution: a mobile power bank connection port anti-loosening structure, including a mobile power bank body 1; an input terminal 2 is provided on the side wall of the mobile power bank body 1, and two output terminals 5 are provided on the bottom of the mobile power bank body 1; a display screen 3 and a switch 4 are electrically connected to the surface of the mobile power bank body 1; two sliding chambers 6 are fixedly connected to the bottom of the mobile power bank body 1; a U-shaped plate 7 is slidably connected to the inner wall of the sliding chamber 6; two springs 8 are fixedly connected to one side of the U-shaped plate 7; the other end of the spring 8 is fixedly connected to the inner wall of the sliding chamber 6; and two support plates 9 are fixedly connected to the bottom of the mobile power bank body 1. Through the U-shaped plate 7 and the springs 8 in the sliding chamber 6, a stable clamping force is formed on the connection cable after it is inserted into the output terminal 5. The elastic force of the springs 8 continuously applies clamping force, effectively preventing the connection cable from loosening or falling off due to accidental contact, vibration, or pulling, ensuring a stable and reliable electrical connection between the output terminal 5 of the mobile power bank and the connection cable, and guaranteeing the normal power supply of the electrical equipment.

[0023] Reference Figure 4 As shown in this embodiment: a groove is formed on the surface of the sliding chamber 6, a connecting plate 10 is fixedly connected to the surface of the U-shaped plate 7, and an operating block 11 is fixedly connected to the surface of the connecting plate 10. The surface of the connecting plate 10 is slidably connected to the groove of the sliding chamber 6. Through the groove on the surface of the sliding chamber 6, in conjunction with the connecting plate 10 and the operating block 11 on the U-shaped plate 7, the user can easily move the U-shaped plate 7 along the groove by moving the operating block 11. This facilitates flexible control of the opening and closing of the U-shaped plate 7 when inserting or removing the connecting wire, which simplifies the operation process and ensures the accuracy of operation during clamping and anti-loosening, thus improving the overall ease of use.

[0024] Reference Figure 4As shown in this embodiment: an adsorption sheet 12 is fixedly connected to the side of the U-shaped plate 7 near the support plate 9, and a magnetic suction sheet 13 is fixedly connected to the side of the support plate 9 near the adsorption sheet 12. The magnetic suction sheet 13 is adsorbed and connected to the adsorption sheet 12. When the output terminal 5 is not in use, the U-shaped plate 7 can be adsorbed and fixed to the magnetic suction sheet 13 on the support plate 9 through the adsorption sheet 12, so that the U-shaped plate 7 and the support plate 9 together form a shielding structure for the output terminal 5, which can effectively prevent dust, impurities, etc. from entering the interior of the output terminal 5, and at the same time prevent external objects from accidentally touching the output terminal 5 and causing damage, thus playing a good protective role and extending the service life of the output terminal 5.

[0025] Reference Figure 4 As shown in this embodiment: a telescopic rod 14 is fixedly connected to the side of the U-shaped plate 7 away from the adsorption sheet 12, and the other end of the telescopic rod 14 is fixedly connected to the inner wall of the sliding chamber 6. The telescopic rod 14 connected to the side of the U-shaped plate 7 away from the adsorption sheet 12, with its other end fixed to the inner wall of the sliding chamber 6, can guide and limit the sliding of the U-shaped plate 7, preventing the U-shaped plate 7 from shifting, tilting, or becoming unstable under the action of the spring force 8 or when affected by external forces, ensuring that the U-shaped plate 7 always moves smoothly along the preset trajectory, thereby ensuring a stable and reliable clamping and anti-loosening effect on the connecting wire.

[0026] Reference Figure 4 As shown in this embodiment, two anti-slip pads 15 are fixedly connected to the inner wall of the U-shaped plate 7, and anti-slip grooves are formed on the surface of the anti-slip pads 15. The anti-slip pads 15 on the inner wall of the U-shaped plate 7, together with the anti-slip grooves on the surface, can increase the friction between the pads and the connecting wires, effectively preventing the connecting wires from sliding or shifting under clamping conditions. Especially when the power bank is being carried or slightly shaken, it can further improve the tightness of the clamping, ensuring the continuous and stable electrical connection. At the same time, the anti-slip pads 15 can also protect the surface of the connecting wires, avoiding wear caused by excessive clamping.

[0027] Reference Figure 1 As shown in this embodiment: a sealing plug 16 is slidably connected to the inner wall of the input terminal 2, and a flexible rope 17 is fixedly connected to the surface of the sealing plug 16. One end of the flexible rope 17 is fixedly connected to the side wall of one end of the power supply body. The sealing plug 16 slidably connected to the inner wall of the input terminal 2 can tightly seal the port when the input terminal 2 is not in use, effectively preventing dust, moisture and other impurities from entering, avoiding contamination or corrosion of internal components, and playing a good sealing and protective role. The sealing plug 16 is connected to the power supply body 1 through the flexible rope 17, which can prevent the sealing plug 16 from being lost after being removed.

[0028] Reference Figure 1As shown in this embodiment, a dustproof and waterproof membrane 18 is adhered to the surfaces of the display screen 3 and the switch 4. The dustproof and waterproof membrane 18 adhered to the surfaces of the display screen 3 and the switch 4 effectively prevents dust from adhering to the surface and affecting display clarity and operational sensitivity. It also isolates them from corrosion caused by water vapor and liquid splashes, preventing problems such as display screen 3 malfunction and switch 4 failure due to dust accumulation or water ingress. This extends the service life of the display screen 3 and the switch 4 without affecting normal observation and operation, thus improving the reliability of the power bank.

[0029] Reference Figure 3 As shown in this embodiment, a handle 19 is fixedly connected to the side of the power bank body 1 away from the switch 4. The handle 19 is made of elastic rubber. The elastic rubber handle 19 on the power bank body 1 provides a convenient grip for the user, making it easy to pick up or carry the power bank at any time, thus improving portability. At the same time, the elastic rubber material has good flexibility and anti-slip properties, conforming to the contour of the hand when gripped, reducing hand pressure, improving grip comfort, and preventing it from slipping out of the hand, thus balancing the convenience of carrying and the safety of use.

[0030] Working principle: When output end 5 is in use, the user moves the operating block 11, causing the connecting plate 10 to slide along the groove of the sliding chamber 6, thereby causing the U-shaped plate 7 to compress the spring 8 and move inward into the sliding chamber 6. At this time, the connecting wire can be inserted into output end 5. After releasing the operating block 11, the elastic force of the spring 8 pushes the U-shaped plate 7 back to its original position, so that it cooperates with the support plate 9 to form a stable clamping force on the connecting wire. At the same time, the anti-slip pad 15 and anti-slip groove on the inner wall of the U-shaped plate 7 increase the friction force, further preventing the connecting wire from loosening. The telescopic rod 14 ensures that the U-shaped plate 7 moves smoothly along the preset trajectory, ensuring a stable clamping effect. When output end 5 is not in use, the U-shaped plate 7 returns to its original position under the action of the spring 8, and its surface... The adsorption sheet 12 on the surface is adsorbed and fixed to the magnetic sheet 13 on the support plate 9. The U-shaped plate 7 and the support plate 9 together form a shielding structure, which protects the output end 5 from dust and contact. When the input end 2 is not in use, the sealing plug 16 is tightly sealed by sliding connection and connected to the power bank body 1 by soft rope 17 to prevent loss and prevent dust and moisture from entering. When in use, the sealing plug 16 can be removed to connect the charging cable normally. In addition, the dustproof and waterproof film 18 on the surface of the display screen 3 and the switch 4 provides dustproof and waterproof protection without affecting normal observation and operation. The handle 19 made of elastic rubber provides a convenient and comfortable grip experience for carrying the power bank.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
