Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and in particular to a power cord that is easy to expand and splice. Background Technology

[0002] As a basic electronic connection device, the technology of power cords can be traced back to the early development of the power industry. With the increasing popularity of electrical equipment and the continuous progress of technology, the design and manufacturing of power cords have also undergone many changes to meet the needs of different application scenarios.

[0003] When using existing power cords, the length is often insufficient, necessitating extension and splicing. However, during extension and splicing, the power plug and splice connector cannot be properly secured, leading to detachment during use. This loose connection results in poor contact, increased resistance, and heat generation, potentially causing overheating or even a fire over time. Furthermore, unstable power cord connections cause current fluctuations, which can damage connected electronic devices, particularly precision instruments and high-power equipment.

[0004] To address the above issues, we have introduced a power cord that is easy to expand and connect. Utility Model Content

[0005] This utility model discloses a power cord that is easy to expand and connect, aiming to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An expandable power cord includes a power cord body and an expansion power cord. A power plug is fixedly connected to one end of both the power cord body and the expansion power cord. Limiting grooves are formed on both sides of the power plug. A splicing connector is fixedly connected to the end of the expansion power cord away from the power plug. Two fixing blocks are fixedly connected to both sides of the splicing connector. A connecting rod is fixedly connected between each pair of fixing blocks. Limiting hooks are rotatably connected to the outside of each connecting rod, and each limiting hook cooperates with a corresponding limiting groove. A torsion spring is sleeved on the outside of each connecting rod, located between the fixing block and the limiting hook. Both ends of the torsion spring are fixedly connected to one side of the corresponding limiting hook and fixing block.

[0008] The design enables convenient splicing of power cords via a power plug and connector. The use of a limiting groove and a limiting hook ensures a stable connection between the power plug and the connector, preventing the plug from loosening or falling off. A torsion spring provides elasticity to the limiting hook, allowing it to automatically lock when inserted into the limiting groove and easily release when disconnection is required. This simplifies the power cord splicing process, improves the stability and reliability of the connection, and is suitable for occasions where frequent length adjustments are required.

[0009] In a preferred embodiment, a three-pronged power connector is fixedly connected to the end of the power cord body away from the power plug.

[0010] The three-prong plug design allows it to be adapted to various power outlets, improving the versatility and flexibility of the power cord.

[0011] In a preferred embodiment, both ends of the power cord body and the extension power cord, located on one side of the power plug, splice connector, and connection plug, are fixedly connected with anti-bending sheaths.

[0012] The design with a bend-resistant sheath protects the power cord body and both ends of the extension cord, preventing internal wires from breaking or being damaged due to excessive bending.

[0013] In a preferred embodiment, anti-slip protrusions are fixedly connected at equal intervals on both sides of the power plug.

[0014] The design with anti-slip ridges increases the friction between the power plug and your fingers, making plugging and unplugging easier and safer.

[0015] In a preferred embodiment, one end of the limiting hook is provided with an inclined surface that cooperates with the limiting groove.

[0016] The beveled design at one end of the limit hook makes it easier to insert into the limit groove, improving the ease of splicing and ensuring that the limit hook can be quickly locked after insertion.

[0017] In a preferred embodiment, both the power cord body and the extended power cord are designed to be waterproof.

[0018] The waterproof structure protects the power cord body and the internal circuitry of the extension power cord, preventing moisture penetration that could cause short circuits or damage.

[0019] The power cord provided by this utility model, which is easy to expand and connect, has the following advantages:

[0020] In this invention, the combined use of a limiting groove and a limiting hook ensures a stable connection between the power plug and the connector, preventing the plug from becoming loose or falling off. The torsion spring provides elasticity to the limiting hook, allowing it to automatically lock when inserted into the limiting groove. This ensures a secure connection between the power plug and the connector, reducing the risk of leakage due to poor contact and protecting users from electric shock. It also ensures a stable power cord connection, preventing current fluctuations due to loosening, thus reducing damage to electronic equipment, especially precision instruments and high-power devices. Compared to traditional devices, this invention significantly improves operational quality and efficiency. Attached Figure Description

The limiting hooks 8 are used in conjunction with the corresponding limiting grooves 4. Torsion springs 9 are sleeved on the outside of the connecting rod 7 and between the fixing blocks 6 and the limiting hooks 8. Both ends of the torsion springs 9 are fixedly connected to the corresponding limiting hooks 8 and one side of the fixing blocks 6.

[0030] In this embodiment, the power cord is conveniently spliced ​​using the power plug 3 and the connector 5. The cooperation between the limiting groove 4 and the limiting hook 8 ensures a stable connection between the power plug 3 and the connector 5, preventing the plug from loosening or falling off. The torsion spring 9 provides elasticity to the limiting hook 8, enabling it to automatically lock when inserted into the limiting groove 4 and easily release when disconnection is required. This simplifies the splicing process of the power cord, improves the stability and reliability of the connection, and is suitable for occasions where frequent length adjustments are required.

[0031] In a preferred embodiment, a three-pronged power connector 10 is fixedly connected to the end of the power cord body 1 away from the power plug 3.

[0032] In this embodiment, the three-pronged power plug 10 is designed to adapt to various power sockets, improving the versatility and flexibility of the power cord.

[0033] In a preferred embodiment, both ends of the power cord body 1 and the extended power cord 2, and located on one side of the power plug 3, the connector 5 and the power connector 10, are fixedly connected with anti-bending sheaths 11.

[0034] In this embodiment, the design of the anti-bending sheath 11 protects both ends of the power cord body 1 and the extension power cord 2, preventing the internal wires from breaking or being damaged due to excessive bending.

[0035] In a preferred embodiment, anti-slip protrusions 12 are fixedly connected at equal intervals on both sides of the power plug 3.

[0036] In this embodiment, the anti-slip ridge 12 design increases the friction between the power plug 3 and the fingers, making plugging and unplugging operations more convenient and safer.

[0037] In a preferred embodiment, one end of the limiting hook 8 is provided with an inclined surface that cooperates with the limiting groove 4.

[0038] In this embodiment, the beveled design at one end of the limiting hook 8 makes it easier for the limiting hook 8 to be inserted into the limiting groove 4, improving the ease of splicing and ensuring that the limiting hook 8 can be quickly locked after insertion.

[0040] In this embodiment, the waterproof structure protects the internal circuitry of the power cord body 1 and the extended power cord 2, preventing moisture penetration that could cause short circuits or damage.

[0041] Working principle: During use, the user inserts the power plug 3 of the power cord body 1 into a power socket or device. The user aligns the splice 5 of the extension power cord 2 with the power plug 3 of the power cord body 1, ensuring that the limiting hook 8 of the splice 5 is aligned with the limiting grooves 4 on both sides of the power plug 3. When the splice 5 is inserted into the power plug 3, one end of the limiting hook 8 will contact the limiting grooves 4 on both sides of the power plug 3. The inclined structure of the limiting hook 8 will cause the limiting hook 8 to rotate outward along the connecting rod 7. Once the splice 5 is fully inserted, the limiting hook 8 will automatically rotate back to its original position under the action of the torsion spring 9 and lock in the limiting groove 4, achieving automatic locking. This ensures the stability of the splicing and the stability of the power cord connection, preventing current fluctuations due to loosening, thereby reducing damage to electronic equipment, especially precision instruments and high-power equipment. Compared with traditional devices, this greatly improves the quality of operation and efficiency of use.
