Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and in particular to a power cord with a double-ended protection structure. Background Technology

[0002] A power cord is a carrier used to connect electrical appliances to a power source and to transmit current.

[0003] Existing power cords lack protection at the connection points when connecting devices, making them prone to breakage when subjected to external impacts. They are also susceptible to bending and damage when not in use, thus affecting their usability. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of lacking a protection mechanism at the connection end of the power cord. To this end, we propose a power cord with a double-head protection structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a power cord with a double-ended protection structure, comprising a power cord body, both ends of which are equipped with connecting ends, and a protective shell is provided around the connecting ends, one end of which is fixed to the power cord body;

[0006] The protective mechanism includes four protective covers disposed on the top of the protective shell. The four protective covers are distributed in a circle around the protective shell as the axis. Each protective cover has a through hole at both ends. A sliding rod is slidably connected inside the through hole, and one end of the sliding rod is fixed to the protective shell.

[0007] Preferably, the end of the slide bar away from the protective shell is fixed with a limiting block that works in conjunction with the protective cover.

[0008] Preferably, hollow connecting posts are fixed at both ends of the protective cover near the limiting block, and a first spring is sleeved on the surface of the slide rod. One end of the first spring is fixed to the hollow connecting post, and the other end of the first spring is fixed to the limiting block.

[0009] Preferably, the top of the protective cover has an inclined groove, which is a quarter circle.

[0010] Preferably, a limiting ring is fixed at the bottom of the outer surface of the protective shell, a movable cover is fitted on the surface of the protective shell, and a groove is provided on the top of the movable cover to cooperate with the protective cover.

[0011] Preferably, the bottom of the movable cover is provided with a connecting groove, and a second spring is fixed inside the connecting groove. The bottom of the second spring is fixed to the top of the limiting ring.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this utility model, when the power cord body is connected to the device through the connecting end, the top of the protective shell is inserted into the device by moving the protective cover, thus completing the docking of the connecting end. After the connection, the interface part is locked by adjusting the protective cover, thereby achieving protection of the connection. The cooperative design of the protective cover and the protective shell can preferentially absorb the impact when subjected to external force, avoid direct damage to the connecting end, and effectively protect the connection structure.

[0014] In this invention, by controlling the movement of the movable cover, it engages with the groove when the protective cover is closed, thereby achieving synchronous locking of multiple protective plates. The limiting ring restricts the sliding range of the movable cover to prevent it from falling off. At the same time, the second spring fixes the position of the movable cover during transportation or movement to avoid vibration causing locking failure and ensure that the protective structure always remains stable.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-4As shown, this utility model provides a technical solution: a power cord with a double-ended protection structure, including a power cord body 1, with connecting ends 2 installed at both ends of the power cord body 1, and a protective shell 3 surrounding the connecting ends 2. One end of the protective shell 3 is fixed to the power cord body 1. The protection mechanism includes four protective covers 4 disposed on the top of the protective shell 3, the four protective covers 4 being circumferentially distributed around the protective shell 3. Each end of the protective cover 4 has a through hole 5, and a sliding rod 6 is slidably connected inside the through hole 5. One end of the sliding rod 6 is fixed to the protective shell 3. When the power cord body 1 is connected to the device through the connecting ends 2, the through holes 5 are closed. The protective cover 4 is moved to allow the top of the protective shell 3 to be inserted into the equipment, connecting the connection end 2. After connection, the protective cover 4 is used to lock the connection, thus protecting the connection. The cooperation between the protective cover 4 and the protective shell 3 prevents direct damage to the connection end 2 in the event of an impact, thus protecting the connection end 2. When the power cord body 1 is not in use, the four protective covers 4 are moved to cover the top of the protective shell 3, thus enclosing the connection end 2 inside the protective shell 3, protecting the connection end 2 and preventing it from bending.

[0023] Reference Figure 4 As shown in this embodiment: a limiting block 7 is fixed at the end of the slide rod 6 away from the protective shell 3, which is used in conjunction with the protective cover 4. The limiting block 7 is used to limit the protective cover 4 and prevent the protective cover 4 from detaching from the surface of the slide rod 6.

[0024] Reference Figure 4 As shown in this embodiment: hollow connecting posts 8 are fixed at both ends of the protective cover 4 near the limiting block 7. A first spring 9 is sleeved on the surface of the slide rod 6. One end of the first spring 9 is fixed to the hollow connecting post 8, and the other end of the first spring 9 is fixed to the limiting block 7. By setting the first spring 9, the protective cover 4 can quickly cover the protective shell 3 after the connection between the power cord body 1 and the equipment is disconnected. The hollow connecting post 8 provides a fulcrum for the installation of the first spring 9, so as to facilitate the installation of the first spring 9.

[0025] Reference Figure 4 As shown in this embodiment: the top of the protective cover 4 is provided with a slanted groove 10, which is a quarter circle. By opening the slanted groove 10, when the power cord body 1 is directly connected, the protective cover 4 can be opened by itself through the cooperation of the device connector and the slanted groove 10, thereby reducing the operation steps.

[0026] Reference Figure 2 and Figure 5As shown in this embodiment: a limiting ring 11 is fixed to the bottom of the outer surface of the protective shell 3, and a movable cover 12 is fitted on the surface of the protective shell 3. The top of the movable cover 12 is provided with a groove 13 that cooperates with the protective cover 4. The movable cover 12 is used to limit the protective cover 4. When the protective cover 4 covers the protective shell 3, the movable cover 12 moves to release the protective cover 4 from the groove 13, thereby limiting multiple protective covers 4 at the same time and preventing the protective covers 4 from opening. The limiting ring 11 is used to limit the movable cover 12 and prevent the movable cover 12 from sliding to the surface of the power cord body 1.

[0027] Reference Figure 5 As shown in this embodiment: the bottom of the movable cover 12 is provided with a connecting groove 14, and a second spring 15 is fixed inside the connecting groove 14. The bottom of the second spring 15 is fixed to the top of the limiting ring 11. By setting the second spring 15, the movable cover 12 is limited when it limits the protective cover 4, so as to prevent the movable cover 12 from losing its limit on the protective cover 4 during the process of picking up and transporting the power cord body 1.

[0028] Working principle: When the power cord body 1 is connected to the device through the connecting end 2, the movement of the protective cover 4 allows the top of the protective shell 3 to insert into the device, completing the docking of the connecting end 2. After connection, the interface is tightened by adjusting the protective cover 4, thus protecting the connection. The design of the protective cover 4 and the protective shell 3 can preferentially absorb the impact when subjected to external force, avoiding direct damage to the connecting end 2 and effectively protecting the connection structure. When the power cord body 1 is not in use, the four protective covers 4 can move inward synchronously, completely covering the top of the protective shell 3, and enclosing the connecting end 2 within the internal space of the protective shell 3. This closed state can prevent the connecting end 2 from being damaged by external bending and also prevent dust or foreign objects from entering the interface. The limiting block 7 is used to limit the protection. The movement trajectory of cover 4 prevents it from detaching from the surface of slide rod 6; after the power cord body 1 is disconnected from the equipment, the first spring 9 drives the protective cover 4 to quickly return to the closed state, while the hollow connecting column 8 provides a fixed fulcrum for the first spring 9 to ensure the stable operation of the elastic element; in addition, the design of the inclined groove 10 allows the protective cover 4 to be automatically pushed open when the equipment connector is inserted, realizing manual operation and improving ease of use. By controlling the movement of the movable cover 12, it engages with the groove 13 when the protective cover 4 is closed, realizing the synchronous locking of multiple protective plates. The limiting ring 11 limits the sliding range of the movable cover 12 to prevent it from falling off; at the same time, the second spring 15 fixes the position of the movable cover 12 during transportation or movement to avoid vibration causing locking failure and ensure that the protective structure always remains stable.
