Description

Technical Field

[0001] This utility model relates to the field of electrical equipment manufacturing technology, and in particular to a power cord plug with an anti-derailment structure. Background Technology

[0002] Electrical equipment manufacturing refers to the process from the procurement of raw materials to the manufacturing of the final product, involving technologies from multiple disciplines such as electrical, electronic, and mechanical. In the use of electrical equipment, the power cord plug refers to the device that connects electrical appliances and other devices to the power source.

[0003] In existing power cord plugs, the power cord is usually plugged into one end of the connector. Under the action of external force, it cannot get enough physical support to disperse and offset the external force, which can easily cause the power cord to loosen from the plug body. This not only makes the equipment unable to work properly, but also significantly reduces the stability and safety during the use of electricity. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing technology, there are power cord plugs. When in use, due to the lack of sufficient physical support to disperse and offset external forces, the power cord is prone to loosening from the plug body. This not only affects the normal use of the equipment, but also reduces the stability and safety of the power supply. Therefore, we propose a power cord plug with an anti-detachment structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a power cord plug with an anti-detachment structure, comprising a plug body, an auxiliary block fixed to one end of the plug body, inserts fixed to both ends of one side of the auxiliary block, a power cord body installed at the other end of the plug body, an inner sheath fixed to the surface of the power cord body near one end of the plug body, a left clamping block provided on one side of the inner sheath, a right clamping block provided on the other side of the inner sheath, an upper housing fixed to both sides of the left clamping block, a lower housing fixed to both ends of the right clamping block, a lower protrusion provided inside the lower housing, a pull rod fixed to one end of the lower protrusion, a circular plate fixed to one end of the pull rod, an upper protrusion slidably connected to one side of the lower protrusion, the lower protrusion and the upper protrusion being slidably connected, an elastic locking block fixed to one side of the upper protrusion, and a T-shaped groove for cooperating with the elastic locking block being provided inside the upper housing.

[0006] Preferably, a first slider is fixed to the other side of the lower protrusion, and a first groove is provided inside the lower housing to cooperate with the first slider.

[0007] Preferably, a spring is fixed to the end of the lower protrusion away from the pull rod, and the other end of the spring is fixed to the interior of the lower housing.

[0008] Preferably, a second slider is fixed at both ends of the upper protrusion, and a second groove is provided inside the lower housing to cooperate with the second slider.

[0009] Preferably, push rods are slidably connected to both ends inside the upper housing, and a push plate is fixed to one end of each push rod.

[0010] Preferably, both ends of the right clamping block are fixed with positioning blocks, and both ends of the left clamping block are provided with positioning grooves that cooperate with the positioning blocks.

[0011] Preferably, the left and right clamping blocks are fixed with convex anti-slip pads on the side near the inner sheath.

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

[0013] In this invention, by aligning the left and right clamping blocks, and then pushing the pull rod to move the lower protrusion, the inclined surface at the top of the lower protrusion exerts a pushing force on the upper protrusion. The upper protrusion then moves the elastic locking block towards the upper housing. During this process, the two ends of the top of the elastic locking block first contact the inclined surface inside the T-slot, and smoothly enter the interior of the T-slot through compression, thereby achieving the connection between the left and right clamping blocks. Through the above-mentioned design, the power cord body is effectively prevented from coming out of the plug body, and the power cord body is tightly clamped inside the plug body, improving the connection stability between the power cord body and the plug body, ensuring the normal operation of electrical equipment, providing additional physical support, effectively dispersing and offsetting external forces, and greatly improving the safety and stability during the use of electricity.

[0019] 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.

[0020] Reference Figures 1-4 As shown, this utility model provides a technical solution: a power cord plug with an anti-detachment structure, including a plug body 1, an auxiliary block 2 fixed to one end of the plug body 1, inserts 3 fixed to both ends of one side of the auxiliary block 2, a power cord body 4 installed at the other end of the plug body 1, an inner sheath 5 fixed to the surface of the power cord body 4 near one end of the plug body 1, a left clamping block 6 provided on one side of the inner sheath 5, a right clamping block 7 provided on the other side of the inner sheath 5, an upper housing 8 fixed to both sides of the left clamping block 6, a lower housing 9 fixed to both ends of the right clamping block 7, a lower protrusion 10 provided inside the lower housing 9, a pull rod 11 fixed to one end of the lower protrusion 10, a circular plate 12 fixed to one end of the pull rod 11, an upper protrusion 13 slidably connected to one side of the lower protrusion 10, the lower protrusion 10 and the upper protrusion 13 are slidably connected, an elastic locking block 14 fixed to one side of the upper protrusion 13, and an opening inside the upper housing 8 for... The T-slot 15 used in conjunction with the elastic locking block 14 aligns the left clamping block 6 and the right clamping block 7, and then pushes the pull rod 11 to move the lower protrusion 10. The inclined surface at the top of the lower protrusion 10 will generate a pushing force on the upper protrusion 13. The upper protrusion 13 will drive the elastic locking block 14 to move towards the upper housing 8. During this process, the two ends of the top of the elastic locking block 14 will first contact the inclined surface opened inside the T-slot 15, and smoothly enter the interior of the T-slot 15 through compression, thereby realizing the connection between the left clamping block 6 and the right clamping block 7. Through the above settings, the power cord body 4 is effectively prevented from coming out of the plug body 1, and the power cord body 4 is tightly clamped inside the plug body 1, which improves the connection stability between the power cord body 4 and the plug body 1, ensures the normal operation of electrical equipment, provides additional physical support, can effectively disperse and offset external forces, and greatly improves the safety and stability during the use of electricity.

[0021] Reference Figure 4As shown in this embodiment: a first slider 16 is fixed on the other side of the lower protrusion 10, and a first groove 17 that cooperates with the first slider 16 is provided inside the lower housing 9. By setting the structure of the first slider 16 and the first groove 17, the movement trajectory of the lower protrusion 10 is effectively constrained, and shaking is avoided.

[0022] Reference Figure 4 As shown in this embodiment: a spring 18 is fixed to one end of the lower protrusion 10 away from the pull rod 11, and the other end of the spring 18 is fixed to the inside of the lower housing 9. Push rods 21 are slidably connected to both ends inside the upper housing 8. A push plate 22 is fixed to one end of the push rod 21. By setting the structure of the spring 18, when the connection between the left clamping block 6 and the right clamping block 7 is released, the push plate 22 is pushed to drive the push rod 21 to squeeze the two ends of the elastic block 14. At the same time, the rebound force of the spring 18 can be used to quickly push the lower protrusion 10 back to the initial position. The lower protrusion 10 will pull the upper protrusion 13 to move, and then the upper protrusion 13 will drive the elastic block 14 away from the inside of the T-slot 15, thereby releasing the connection. The operation is very simple and convenient for the next use.

[0023] Reference Figure 4 As shown in this embodiment: both ends of the upper protrusion 13 are fixed with second sliders 19, and the interior of the lower housing 9 is provided with a second sliding groove 20 that cooperates with the second sliders 19. By setting the structure of the second sliders 19 and the second sliding groove 20, it is ensured that the upper protrusion 13 moves along the prescribed route and to prevent deviation.

[0024] Reference Figure 3 As shown in this embodiment: both ends of the right clamping block 7 are fixed with positioning blocks 23, and both ends of the left clamping block 6 are provided with positioning grooves 24 that cooperate with the positioning blocks 23. By setting the structure of positioning blocks 23 and positioning grooves 24, it is possible to effectively prevent the left clamping block 6 and the right clamping block 7 from shifting or loosening during use, thereby enhancing the firmness of the connection and the anti-fall-off effect.

[0025] Reference Figure 3 As shown in this embodiment: a convex anti-slip pad 25 is fixed on the side of the left clamping block 6 and the right clamping block 7 near the inner sheath 5. By setting the structure of the convex anti-slip pad 25, the friction between the power cord body 4 and the contact surfaces of the left clamping block 6 and the right clamping block 7 can be effectively increased, thereby preventing the power cord body 4 from sliding or shifting during use, ensuring a more secure and stable connection, and reducing the direct friction between the left clamping block 6, the right clamping block 7 and the power cord body 4, thereby extending the service life of the power cord body 4.

[0026] Working principle: The user aligns the left clamp 6 and right clamp 7, then pushes the lever 11 to move the lower protrusion 10. The inclined surface at the top of the lower protrusion 10 exerts a pushing force on the upper protrusion 13. The upper protrusion 13 then moves the elastic locking block 14 towards the upper housing 8. During this process, the two ends of the top of the elastic locking block 14 first contact the inclined surface inside the T-slot 15, and smoothly enter the interior of the T-slot 15 through compression, thereby achieving the connection between the left clamp 6 and the right clamp 7. Through the above setting, the power cord body 4 is effectively prevented from being connected. The power cord body 4 is tightly clamped inside the plug body 1 after being disengaged from the plug body 1, improving the connection stability between the power cord body 4 and the plug body 1, ensuring the normal operation of the electrical equipment, providing additional physical support, effectively dispersing and offsetting external forces, and greatly improving safety and stability during power use. The structure of the first slider 16 and the first groove 17 effectively constrains the movement trajectory of the lower protrusion 10, preventing wobbling. The spring 18 structure allows for release of the connection between the left clamping block 6 and the right clamping block 7. Pushing the push plate 22 causes the push rod 21 to press against both ends of the elastic block 14. Simultaneously, the rebound force of the spring 18 quickly pushes the lower protrusion 10 back to its initial position. The lower protrusion 10 then pulls the upper protrusion 13 to move, causing the upper protrusion 13 to move the elastic block 14 away from the T-slot 15, thus disengaging the connection. The operation is very simple and convenient for future use. The structure of the second slider 19 and the second slide groove 20 ensures that the upper protrusion 13 moves along a predetermined path, preventing deviation. The positioning block 23 and... The structure of the positioning groove 24 can effectively prevent the left clamp 6 and the right clamp 7 from shifting or loosening during use, enhancing the firmness and anti-detachment effect of the connection. By setting the structure of the convex anti-slip pad 25, the friction between the power cord body 4 and the contact surfaces of the left clamp 6 and the right clamp 7 can be effectively increased, thereby preventing the power cord body 4 from sliding or shifting during use, ensuring a more firm and stable connection, and reducing the direct friction between the left clamp 6, the right clamp 7 and the power cord body 4, thereby extending the service life of the power cord body 4.
