Description

Technical Field

[0001] This utility model relates to the field of power cord structure design technology, and in particular to an environmentally friendly power cord with a flame-retardant structure. Background Technology

[0002] With the increasing popularity of electrical appliances and the growing awareness of environmental protection and safety, power cords with flame-retardant properties and made of environmentally friendly materials have been widely used, especially in high-power household appliances such as rice cookers, electric ovens, and electric water heaters, providing power transmission assurance for the safe operation of these appliances.

[0003] In existing technologies, environmentally friendly power cords with flame-retardant properties typically employ a multi-layered composite structure design. A typical structure, from the inside out, generally includes a conductor layer, an insulation layer, a filler layer, a wrapping layer, a flame-retardant layer, and an outer sheath layer. The flame-retardant layer constitutes the core flame-retardant structure of the power cord, effectively preventing the spread of flames and improving the fire safety performance of the power cord. To meet environmental protection requirements, the conductor layer, insulation layer, flame-retardant layer, and outer sheath layer are all made of environmentally friendly materials. For example, the conductor layer uses lead-free plated copper conductors, the insulation layer and outer sheath layer use environmentally friendly polyvinyl chloride or environmentally friendly polyethylene materials, and the flame-retardant layer often uses environmentally friendly flame-retardant polyolefins or flame-retardant rubber materials. This achieves both flame-retardant effect and power transmission function while reducing environmental pollution.

[0004] However, existing environmentally friendly power cords with flame-retardant structures still have significant drawbacks in practical use: Because high-power appliances require high power supply stability, the plug and socket of the power cord are typically designed for a tight fit to avoid overheating and other safety hazards caused by poor contact. However, this design makes plugging and unplugging difficult, often requiring significant external force. During this process, users are prone to dragging the power cord itself instead of holding the plug. Over time, or with a single instance of significant external force, mechanical stress concentration can occur at the connection point between the power cord and the plug, leading to cracking and peeling of the insulation, flame-retardant layer, and outer sheath, and even conductor breakage. This not only affects the normal use of the power cord but may also cause electric shock, short circuits, and other safety accidents due to exposed wiring, seriously impacting the product's safety and lifespan. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly power cord with a flame-retardant structure that makes it easy to plug and unplug the plug in the socket of the appliance, reduces the phenomenon of the wire and plug connection being pulled, and improves the safety and service life.

[0006] This utility model discloses an environmentally friendly power cord with a flame-retardant structure, including a power plug, which is connected to an appliance plug via a wire, and further comprising:

[0007] The mounting base is symmetrically configured in two parts, and the two mounting bases are respectively installed on the two opposite side walls of the electrical plug. The two mounting bases are integrally formed with the electrical plug.

[0008] The support rods are symmetrically arranged in two, with one end of each support rod installed in a mounting base. The two support rods are arranged in parallel, and the connection point between the wire and the electrical plug is located between the two support rods. The other end of each support rod is provided with a hinge seat.

[0009] Pull handles are provided. There are two pull handles, which are symmetrically arranged on both sides of the two support rods. The two pull handles are respectively hinged to two hinge seats at the closer ends. The side wall of each hinge seat away from the electrical plug is provided with a limiting baffle to restrict the rotation angle of the pull handle.

[0010] Furthermore, it also includes a stabilizing rod, which is located between the two support rods, and the two opposite sidewalls of the stabilizing rod are respectively connected to the two opposite sidewalls of the two support rods.

[0011] Furthermore, both of the aforementioned pull handles are configured as arc-shaped structures that converge toward the electrical plug.

[0012] Furthermore, the side wall of the stabilizing rod is provided with a fastening hole, which is used to fix the wire.

[0013] Furthermore, an elastic clip is provided on the horizontal surface of the stabilizing rod, and the size of the elastic clip is adapted to the size of the wire.

[0014] Furthermore, the support rod is provided with an anti-disengagement plate at the location within the mounting base.

[0015] Furthermore, a protective cushioning pad is provided on the concave arc-shaped sidewall of the pull handle facing the electrical plug.

[0016] Furthermore, multiple sets of anti-slip ridges are provided on the convex arc-shaped sidewall of the pull handle away from the electrical plug.

[0019] 2. Enhanced structural stability and durability: The one-piece molded mounting base strengthens the connection between the support rod and the electrical plug, while the anti-detachment plate prevents the support rod from falling out of the mounting base; the stabilizing rod connects the two support rods to form a stable frame, further strengthening the overall structure and extending the service life of the power cord.

[0020] 3. Enhanced safety: By reducing damage to connection points, safety accidents such as electric shock and short circuits caused by exposed conductors are avoided. Combined with the flame-retardant structure of the wire itself, the safety performance is doubly improved.

[0021] 4. Optimized user experience: The curved pull handle conforms to the hand's force application habits, the anti-slip ridges increase grip friction, and the protective cushioning pad can improve hand comfort when unplugging the plug, thus improving the comfort and convenience of operation.

[0022] 5. Adaptable to wire fixing needs: The fastening holes and elastic clips on the stabilizing rod can help fix the wires, reducing the extra damage to the connection parts caused by wire shaking, and adapting to the wiring needs in different usage scenarios. Attached Figure Description

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 3 As shown,

[0029] This utility model discloses an environmentally friendly power cord with a flame-retardant structure, including a power plug 1, wherein the power plug 1 is connected to an electrical plug 2 via a wire 5, and further comprising:

[0030] Mounting base 3, two mounting bases 3 are symmetrically arranged, and the two mounting bases 3 are respectively installed on the two opposite side walls of the electrical plug 2. The two mounting bases 3 are integrally formed with the electrical plug 2.

[0031] Support rod 4, two support rods are symmetrically arranged, one end of the two support rods 4 are respectively installed in two mounting seats 3, the two support rods 4 are arranged in parallel, and the connection part of the wire 5 and the electrical plug 2 is located between the two support rods 4, and the other end of the two support rods 4 are provided with a hinge seat 6.

[0032] Pull handle 7, there are two pull handles 7, the two pull handles 7 are symmetrically arranged on both sides of the two support rods 4, the two pull handles 7 are respectively hinged to the two hinge seats 6 at the closer ends, and the two hinge seats 6 are provided with limiting baffles 8 on the side wall away from the electrical plug 2 to limit the rotation angle of the pull handle 7.

[0033] In this embodiment,

[0034] Mounting base 3: It is connected to the electrical plug 2 by an integral molding process, which not only ensures a firm fixation to the electrical plug 2, but also provides a stable mounting carrier for the support rod 4, ensuring that it does not loosen under stress;

[0035] Support rod 4: One end is fixed to the mounting base 3, and the other end carries the hinge base 6, which provides support and force transmission for the pull handle 7; the two support rods 4 are set in parallel and the spacing is appropriate, which encloses the connection part of the wire 5 and the electrical plug 2 in the middle to form a physical protective barrier.

[0036] Hinge 6: Serves as the fulcrum for the rotation of the pull handle 7, enabling the opening and closing rotation of the pull handle 7 and providing a structural basis for users to adjust the grip angle;

[0037] Limiting baffle 8: Located on the side wall of the hinge seat 6 away from the electrical plug 2, it can prevent the handle 7 from turning outwards excessively, so that the handle is always kept within a reasonable angle range that is convenient for the hand to apply force, and ensures the efficiency of force transmission during plugging and unplugging.

[0038] Furthermore, when the wire 5 is removed and not in use, it can be wrapped around the two pull handles 7 in a figure-eight pattern. Therefore, after the pull handles 7 are unfolded, they can not only help to disassemble the electrical plug 2, but also store the wire 5.

[0039] As a preferred embodiment of the above, a stabilizing rod 9 is also included. The stabilizing rod 9 is located between the two support rods 4, and the two opposite sidewalls of the stabilizing rod 9 are respectively connected to the two opposite sidewalls of the two support rods 4.

[0040] In this embodiment,

[0041] Stabilizing rod 9: It connects the two support rods 4 laterally, integrating the scattered support rods 4 into an overall frame structure, which greatly improves the bending and deformation resistance of the support rods 4, prevents the support rods 4 from shifting due to uneven force during insertion and removal, and further strengthens the protection of the middle connection part.

[0042] As a preferred embodiment of the above, both pull handles 7 are configured as arc-shaped structures that converge toward the electrical plug 2;

[0043] In this embodiment,

[0044] Arc-shaped pull handle 7: It adopts an arc-shaped design that converges towards the electrical plug 2, which perfectly fits the natural curve of the hand when holding it, allowing users to easily hold it in a wrap-around manner, making it easier to concentrate the force of plugging and unplugging, and reducing the intensity of operation.

[0045] As a preferred embodiment of the above embodiment, the side wall of the stabilizing rod 9 is provided with a fastening hole, and the fastening hole is fixedly fitted with the wire 5.

[0046] In this embodiment,

[0047] Fastening hole: It is opened through the side wall of the stabilizing rod 9 and is tightly fitted and fixed to the outer wall of the wire 5 to achieve a rigid connection between the wire 5 and the stabilizing rod 9, restricting the axial and radial sway of the wire 5 and reducing the fatigue wear caused by swaying to the connection part.

[0048] As a preferred embodiment of the above embodiment, an elastic clip 10 is provided on the horizontal surface of the stabilizing rod 9, and the size of the elastic clip 10 is adapted to the size of the wire 5;

[0049] In this embodiment,

[0050] Elastic clip 10: Made of elastic material, it is installed on the horizontal surface of the stabilizing rod 9. Its opening size can be adapted to wires 5 of different diameters by elastic deformation. It clamps the wires 5 by elastic tension, which can not only help fix the line, but also make it easy to adjust the fixing position according to the wiring requirements.

[0051] When storing the power cord 5 using the two pull handles 7, after the power cord 5 is wrapped around the two pull handles 7, the power cord 5 at the base of the power plug 1 can be clipped onto the elastic clip 10, which greatly improves the storage effect.

[0052] As a preferred embodiment of the above embodiment, the support rod 4 is provided with an anti-disengagement plate 11 at the part located inside the mounting base 3;

[0053] In this embodiment,

[0054] Anti-detachment plate 11: integrally formed at the end of the support rod 4 that extends into the mounting base 3, in the form of a barb-shaped structure, which can engage with the mounting base 3 to prevent the support rod 4 from coming out of the mounting base 3 under the repeated action of long-term insertion and removal force, thus ensuring the long-term reliability of the overall structure. The part of the support rod 4 located in the mounting base 3 and the anti-detachment plate 11 are integrally injection molded with the mounting base 3.

[0055] As a preferred embodiment of the above embodiment, a protective buffer pad 12 is provided on the concave arc sidewall of the pull handle 7 facing the electrical plug 2;

[0056] In this embodiment,

[0057] Protective cushioning pad 12: Made of flexible elastic material (such as silicone, sponge, etc.), it is attached to the concave arc surface of the pull handle 7, that is, the inner arc surface that contacts the hand. When the hand grips the handle and applies force, it can fill the gap between the hand and the handle. Through its own deformation, it cushions the pressure of the hand, significantly improving the comfort of the hand during gripping and insertion, and avoiding the problem of hand discomfort caused by hard contact.

[0058] As a preferred embodiment of the above, the convex arc-shaped sidewall of the pull handle 7 away from the electrical plug 2 is provided with a plurality of anti-slip ridges 13;

[0059] In this embodiment,

[0060] Anti-slip ridges 13: When inserting the electrical plug 2, the two pull handles 7 can be brought together and rotated to retract, and then the two pull handles 7 can be held together and pushed forcefully. At this time, the electrical plug 2 can be inserted into the socket of the electrical device. Multiple sets of parallel or mesh-like ridges are set on the convex arc surface of the pull handle 7 away from the electrical plug 2, which can increase the friction between the skin of the hand and the surface of the handle, effectively preventing the hand from slipping due to force when plugging and unplugging, and ensuring stable force application without deviation.

[0061] The working principle of this utility model is as follows:

[0062] When in use, to unplug the appliance plug 2, first rotate and unfold the two pull handles 7. At this time, the pull handles 7 rotate around the hinge seat 6, and the limiting baffle 8 restricts excessive rotation, keeping the handles at the optimal force application angle. The user can place both hands on the concave arc surfaces of the two curved pull handles 7 respectively. The protective cushioning pad 12 directly contacts the hand, providing a comfortable grip, while the anti-slip ridges 13 prevent the hand from slipping. When the user applies an outward pulling force, the pulling force is transmitted sequentially through the pull handles 7 to the hinge seat 6, then through the support rod 4 to the mounting base 3, and finally the mounting base 3 drives the appliance plug 2 to smoothly detach from the appliance socket. Throughout the process, the user does not need to touch the power cord 5, fundamentally avoiding stress concentration caused by dragging at the connection point, and preventing hand slippage. At the same time, the stabilizing rod 9 connects the two support rods 4 into a stable frame, the anti-detachment plate 11 prevents the support rods 4 from falling off, ensuring the stability of the stress-bearing structure; the fastening hole fixes the power cord 5, reducing shaking loss. Through the coordinated operation of all components, the plug can be easily plugged in and out, protecting key parts of the power cord, extending its service life, and improving safety and comfort during use.

[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
