Description

Technical Field

[0001] This utility model relates to the field of waterproof plug-in technology, specifically to a high-power three-core waterproof plug-in. Background Technology

[0002] The term "mop socket" is easy to understand literally; it's a socket that can be dragged on the floor. This type of socket is also known as a power strip. Unlike wall sockets, which are fixed to a corner of the wall, mop sockets usually have a longer power cord. After plugging the plug into another fixed socket, the socket itself can be dragged in various directions, making it convenient to charge various appliances and equipment.

[0003] A search of publication number "CN214754576U" reveals "a one-to-two two-plug power cord, comprising a plug, two tail plugs, and a one-to-two cable. The plug is connected to each of the two tail plugs via the one-to-two cable. The characteristic feature is that the live wire core of the plug and the live wire cores of the two tail plugs are crimped together using a crimp terminal to form the live wire core of the one-to-two cable. The neutral wire core of the plug and the neutral wire cores of the two tail plugs are crimped together using another crimp terminal to form the neutral wire core of the one-to-two cable. This utility model's one-to-two two-plug power cord, with the plug cores crimped to the two tail plug cores using crimp terminals, improves transmission efficiency and is suitable for high-power transmission."

[0004] In practical use, the above design is often limited, specifically: the length of the wire in the above patent is fixed and cannot be adjusted. When the wire is not long enough, it will affect the use of the electrical appliances. When the wire is too long, it will be inconvenient to store and cause fire hazards. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a high-power three-core waterproof plug, including an intermediate block. Side wires are fixedly connected to both ends of the intermediate block. An outer tube is fixedly connected to the lower end of the intermediate block. An assembly sleeve is fixedly connected to the circumferential surface of the outer tube. A first transmission wire is fixedly connected to the lower end of the intermediate block. A conductive post is rotatably connected to the inner circumferential wall of the assembly sleeve.

An adjusting rod is fixedly connected to the lower end of the connecting plate. A connector is fixedly connected to the lower end of the adjusting rod. An angle control mechanism is provided at one end of the assembly sleeve to control the rotation angle of the conductive post.

[0008] Furthermore, the angle control mechanism consists of a ratchet, a pawl, a fixed plate, and a first spring.

[0009] Furthermore, a fixing mechanism is provided on the lower side of the connecting plate. The fixing mechanism consists of multiple fixing slots, a mounting plate, a fixing rod, two second springs, and two force-bearing blocks. The multiple fixing slots are all opened on the circumferential surface of the adjusting rod. The mounting plate is fixedly connected to the lower end of the outer tube. The fixing rod movably passes through one end of the mounting plate and is engaged in one of the fixing slots. The two second springs are fixedly connected to one end of the mounting plate. The two force-bearing blocks are respectively fixedly connected to one end of the two second springs, and both force-bearing blocks are fixedly connected to the fixing rod.

[0010] Furthermore, one end of the mounting plate is fixedly connected to two limiting rods, and one end of each of the two force-bearing blocks is provided with a horizontal hole, and the two force-bearing blocks are slidably connected to the circumferential surfaces of the two limiting rods through the two horizontal holes respectively.

[0011] Furthermore, an anti-detachment disc is fixedly connected to one end of each of the two limiting rods, and the diameter of the two anti-detachment discs is larger than the diameter of the two limiting rods.

[0013] Furthermore, a limiting ring is fixedly connected to the circumferential surface of the conductive post, and a limiting groove is formed on the inner circumferential wall of the rotating collar. The rotating collar is slidably connected to the circumferential surface of the limiting ring through the limiting groove.

[0014] Furthermore, a pulling block is fixedly connected to one end of the fixing rod, and threaded sleeves and threaded shafts are respectively provided on the circumferential surfaces of the two side guides.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. Current is introduced into this device through one of the two side conductors. When the length of the connector needs to be adjusted, the connector is pulled down. At this time, the adjusting rod and the connecting plate will move down. Then, the wire wrapped on the second transmission line is pulled down, and the conductive post rolls. This changes the length of the connector. The current then passes through the first transmission line, the conductive post, the second transmission line, the connecting plate, and the adjusting rod to finally reach the connector. The current is then transmitted to the electrical appliance through the connector. Through the above design, the length of the connector can be conveniently adjusted and controlled.

[0018] Second, when the conductive post rolls, it will drive the ratchet to rotate. The intermittent engagement of the pawl and the ratchet can prevent the ratchet from rotating in the opposite direction, thereby controlling the rotation angle of the conductive post and thus controlling the pulling length of the second transmission line to achieve a certain degree of stability.

[0019] Third, after the connector has moved a certain distance, the adjusting rod can be fixed by the fixing mechanism, thereby fixing the position of the connector and further controlling the connector so that it will not retract unexpectedly during use. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] See attached document Figure 1-7A high-power three-core waterproof plug includes an intermediate block 1, with side wires 2 fixedly connected to both ends of the intermediate block 1. An outer tube 5 is fixedly connected to the lower end of the intermediate block 1, and an assembly sleeve 6 is fixedly connected to the circumferential surface of the outer tube 5. A first transmission wire 14 is fixedly connected to the lower end of the intermediate block 1. A conductive post is rotatably connected to the inner circumferential wall of the assembly sleeve 6. A rotating collar 15 is fixedly connected to the lower end of the first transmission wire 14, and the rotating collar 15 is slidably connected to the circumferential surface of the conductive post. A second transmission wire 32 is wound around the circumferential surface of the conductive post, and a connecting plate 22 is fixedly connected to one end of the second transmission wire 32. The lower end of the connecting plate 22 is fixedly connected to... An adjusting rod 31 is connected to the assembly sleeve 6. The lower end of the adjusting rod 31 is fixedly connected to a connector 7. An angle control mechanism is provided at one end of the assembly sleeve 6. The angle control mechanism is used to control the rotation angle of the conductive column. The angle control mechanism consists of a ratchet 8, a pawl 11, a fixing plate 12, and a first spring 13. The ratchet 8 is rotatably connected to one end of the assembly sleeve 6 through a rotating shaft. The conductive column and the rotating shaft are fixedly connected. The pawl 11 is rotatably connected to one end of the assembly sleeve 6 through a rotating rod. The pawl 11 and the ratchet 8 are intermittently engaged. The fixing plate 12 is fixedly connected to one end of the assembly sleeve 6. The first spring 13 is fixedly connected to the near ends of the fixing plate 12 and the pawl 11.

[0032] In a specific embodiment of this utility model, during actual use, the side wire 2 is first electrically connected to the external conductor. Then, when the distance of the connector 7 needs to be adjusted, the connector 7 is pulled. At this time, the adjusting rod 31 and the connecting plate 22 will move downwards, thereby winding the second transmission wire 32 around the circumference of the conductive post. At this time, the current flows through the first transmission wire 14, the rotating collar 15, the second transmission wire 32, the connecting plate 22, and the adjusting rod 31 to the connector 7. It should be noted that the adjusting rod 31, the connecting plate 22, and the connector 7 are equipped with circuits. The transmission wire 32 is connected to the circuit and conducts electricity to the connector 7. The adjustment rod 31, the connecting plate 22 and the surface of the connector 7 are not charged, thereby increasing the working distance of the connector 7. When the second transmission wire 32 is pulled, the conductive post will inevitably rotate, and the conductive post will drive the ratchet 8 to rotate. The rotation angle of the conductive post is controlled by the intermittent engagement of the pawl 11 and the ratchet 8, thereby controlling the pulling distance of the second transmission wire 32 and improving stability. The intermittent engagement stability of the pawl 11 and the ratchet 8 is improved by the elastic expansion of the first spring 13.

[0033] Please refer to the details. Figure 1-7A fixing mechanism is provided on the lower side of the connecting plate 22. The fixing mechanism consists of multiple fixing slots 23, a mounting plate 25, a fixing rod 24, two second springs 26, and two force blocks 28. The multiple fixing slots 23 are all opened on the circumferential surface of the adjusting rod 31. The mounting plate 25 is fixedly connected to the lower end of the outer tube 5. The fixing rod 24 movably passes through one end of the mounting plate 25 and is snapped into one of the fixing slots 23. The two second springs 26 are fixedly connected to one end of the mounting plate 25. The two force blocks 28 are respectively fixedly connected to one end of the two second springs 26, and the two force blocks 28 are fixedly connected to the fixing rod 24.

[0034] In this embodiment: after the adjusting rod 31 moves a certain distance, the force block 28 is pulled by the elastic pull of the second spring 26. At this time, the fixing rod 24 will move to one end and be inserted into the fixing groove 23. The movement distance of the adjusting rod 31 is locked by the insertion of the fixing rod 24 and the fixing groove 23, thereby improving the stability of the length control of the connector 7.

[0035] Please refer to the details. Figure 1-7 Two limiting rods 27 are fixedly connected to one end of the mounting plate 25. Horizontal holes are opened at one end of each of the two force-bearing blocks 28, and the two force-bearing blocks 28 are slidably connected to the circumferential surfaces of the two limiting rods 27 through the two horizontal holes. Anti-detachment discs 29 are fixedly connected to one end of each of the two limiting rods 27, and the diameters of the two anti-detachment discs 29 are larger than the diameters of the two limiting rods 27.

[0036] In this embodiment: when the force block 28 moves, it can slide on the circumferential surface of the limit rod 27 through the horizontal hole, which improves the horizontal movement stability of the force block 28. The anti-detachment disc 29 can prevent damage caused by excessive movement of the force block 28.

[0037] Please refer to the details. Figure 1-7 One end of the pawl 11 is fixedly connected to a swing block 10. A limiting rod 9 is fixedly connected to the circumferential surface of the assembly sleeve 6. The limiting rod 9 is located on one side of the swing block 10. A limiting ring 17 is fixedly connected to the circumferential surface of the conductive post. A limiting groove 16 is opened on the inner circumferential wall of the rotating collar 15. The rotating collar 15 is slidably connected to the circumferential surface of the limiting ring 17 through the limiting groove 16. One end of the fixed rod 24 is fixedly connected to a pulling block 30. Threaded sleeves 3 and threaded shafts 4 are respectively provided on the circumferential surfaces of the two side conductors 2.

[0038] In this embodiment: when the pawl 11 swings, it will drive the swing block 10 to swing. The swing arc of the swing block 10 is controlled by the limiting rod 9 to prevent the pawl 11 from swinging excessively. When the conductive post rotates, it rotates in the limiting groove 16 through the limiting ring 17 to improve the smoothness of the connection between the conductive post and the rotating collar 15. The threaded sleeve 3 and the threaded shaft 4 can be used to easily connect the side wire 2 and the external power supply, improving the waterproofness.

[0039] Preferably, a stabilizing groove 18 is provided on the inner circumference of the outer tube 5, and a stabilizing block 19 is fixedly connected to the circumferential surface of the connecting plate 22. When the connecting plate 22 moves, it will drive the stabilizing block 19 to slide in the stabilizing groove 18, thereby improving the vertical movement stability of the connecting plate 22.

[0040] Preferably, a vertical rod 20 is fixedly connected to the lower inner wall of the outer tube 5, and a stabilizing hole is provided at the upper end of the connecting plate 22. The connecting plate 22 slides on the circumferential surface of the vertical rod 20 through the stabilizing hole, thereby improving the vertical movement stability of the connecting plate 22. The anti-detachment plate 21 fixedly connected to the upper end of the vertical rod 20 can prevent the connecting plate 22 from sliding excessively.

[0041] Working principle: In actual use, first connect the side wire 2 to the external electrical connection. Then, when it is necessary to adjust the distance of the connector 7, pull the connector 7. At this time, the adjusting rod 31 and the connecting plate 22 will move downward, thereby winding the second transmission wire 32 around the circumference of the conductive post. At this time, the current flows through the first transmission wire 14, the rotating collar 15, the second transmission wire 32, the connecting plate 22, and the adjusting rod 31 to the connector 7. It should be noted that the adjusting rod 31, the connecting plate 22, and the connector 7 are equipped with circuits. The second transmission wire 32... The device is connected to the circuit and conducts electricity to the connector 7. The surfaces of the adjusting rod 31, connecting plate 22, and connector 7 are not charged, thereby increasing the working distance of connector 7. When the second transmission line 32 is pulled, the conductive post will inevitably rotate, and the conductive post will drive the ratchet 8 to rotate. The rotation angle of the conductive post is controlled by the intermittent engagement of the pawl 11 and the ratchet 8, thereby controlling the pulling distance of the second transmission line 32 and improving stability. The intermittent engagement stability of the pawl 11 and the ratchet 8 is improved by the elastic expansion of the first spring 13.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
