Description

Technical Field

[0001] This utility model relates to the field of plug technology, and specifically to a plug. Background Technology

[0002] Many portable electrical appliances connect to power cords using a combination of plugs and sockets in a triangular pattern, such as electric kettles. To reduce the contact resistance between the plug and socket, the fit is very tight, often requiring considerable force to separate them.

[0003] To facilitate the removal of a plug from a socket, patent number 202022903335.8 discloses a power plug with easy removal capability. The plug includes a female plug body and an easy-removing device. This device includes a rotating shaft and a driving component. The driving component comprises a pushing part for pushing against the socket surface and a handle part for rotating the pushing part to push against the socket surface. The pushing part is rotatably connected to the plug body via the rotating shaft. Two driving components are symmetrically arranged on the left and right sides of the plug body. This easy-removing device uses a lever principle to push against the socket surface, achieving the separation action of the plug from the socket. The structure is simple and effortless.

[0004] However, in actual operation, this technical solution also has some shortcomings. For example, the split structure between the rotating shaft and the driving component increases the number of parts in the plug, thereby increasing manufacturing and maintenance costs. Furthermore, the lack of a necessary linkage structure between the two driving components means their actions are independent. Users cannot simultaneously drive both components to move synchronously, potentially causing the plug to disengage from the socket at an angle. This not only increases the risk of physical damage to both the plug and socket, raising maintenance costs and replacement frequency, but also, during the tilting movement of the plug, uneven force increases the friction on the socket, further hindering the smooth removal of the plug, reducing operational efficiency, and impacting the user experience. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a plug.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A plug includes a plug body, a first driving member, and a second driving member. The plug body includes a plug portion and a wrapping portion that wraps around the rear end of the plug portion. The plug portion is characterized in that: two mounting portions that are respectively connected to the first driving member and the second driving member are integrally formed on the rear end of the plug portion. One end of each of the two mounting portions protrudes outside the wrapping portion and is provided with a pivot hole. The first driving member and the second driving member are both integrally formed with a pivot portion that can be rotatably fitted in the pivot hole.

[0008] In this utility model, the first driving member is provided with a first arc-shaped tooth, and the second driving member is provided with a second arc-shaped tooth that meshes with the first arc-shaped tooth. The first driving member and the second driving member operate synchronously based on the meshing transmission of the first arc-shaped tooth and the second arc-shaped tooth.

[0009] In this utility model, the front end of the plug is a plug end for insertion into a socket, the plug end is provided with a power connection hole, the power connection hole is provided with a power connection component, and the wrapping part is provided with a power cord for connecting and supplying power to the power connection component.

[0010] In this utility model, a side inlet is provided on one side of the mounting part for the rotating shaft part to be inserted into the rotating shaft hole, and the side inlet is provided to penetrate and communicate with the rotating shaft hole radially.

[0011] In this invention, the inlet width of the side inlet gradually decreases from front to back, and the minimum width of the side inlet is less than the diameter of the pivot hole.

[0012] In this utility model, both the first driving member and the second driving member include a handle portion and an upper linkage portion and a lower linkage portion integrally formed and connected to the front end of the handle portion. The front end of the upper linkage portion is provided with an upper pushing portion or / and the front end of the lower linkage portion is provided with a lower pushing portion. The upper and lower ends of the rotating shaft portion are integrally formed and connected to the upper linkage portion and the lower linkage portion, respectively.

[0013] In this utility model, the upper linkage part and the lower linkage part are respectively covered on the upper and lower parts of the plug body. The upper linkage part and the lower linkage part of the first driving member are integrally formed with the first arc-shaped tooth part, and the upper linkage part and the lower linkage part of the second driving member are integrally formed with the second arc-shaped tooth part. Each first arc-shaped tooth part meshes with one second arc-shaped tooth part.

[0014] In this utility model, the bottom of the upper pushing part extends downward and protrudes to form a pushing reinforcement part, the front end face of the pushing reinforcement part is flush with the front end face of the upper pushing part, and the upper front end of the wrapping part is provided with a pushing receiving groove for accommodating the pushing reinforcement part.

[0015] In this utility model, a drive mating groove is formed between the upper linkage part and the lower linkage part for the installation part to be inserted, and the rotating shaft part is located in the drive mating groove.

[0016] In this utility model, a first filling groove is provided on the rear end face of the plug part, and a plurality of first filling holes communicating with the first filling groove are provided on the outer rear end face of the plug part. A second filling groove is provided at one end of the mounting part facing another mounting part, and at least part of the wrapping part is filled in the first filling groove, the first filling holes and the second filling groove.

[0017] The beneficial effects of this utility model are as follows: Firstly, two mounting portions are integrally formed at the rear end of the plug, connecting the first and second driving components respectively. Both the first and second driving components have integrally formed pivot portions that rotatably engage with the pivot holes in the mounting portions. This integral design of the mounting portions and pivot portions simplifies the plug's structure, reduces the number of parts, and improves the overall stability and durability of the plug. Simultaneously, the first driving component has a first arc-shaped tooth, and the second driving component has a second arc-shaped tooth that meshes with the first arc-shaped tooth. This design allows the first and second driving components to achieve synchronous movement based on the meshing transmission of the arc-shaped teeth. During operation, the user only needs to drive one driving component, and the other driving component will move synchronously, thus avoiding the problem of the plug tilting and disengaging from the socket. This not only reduces the risk of physical damage to the plug and socket, lowers maintenance costs and replacement frequency, but also ensures uniform force on the plug during the pulling process, reduces friction, improves operating efficiency, and enhances the user experience. When this utility model is in operation, the socket is pushed outwards simultaneously from both above and below, causing the plug and socket to separate coaxially, making the process smoother and easier.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0027] Reference Figure 1-5 A plug includes a plug body, a first driving member 1, and a second driving member 2. The plug body includes a plug portion 3 and a wrapping portion 4 that wraps around the rear end of the plug portion 3. Both the plug portion 3 and the wrapping portion 4 are manufactured using injection molding. The hardness of the plug portion 3 is greater than that of the wrapping portion 4. The front end of the plug portion 3 is a plug-in end for insertion into a socket 100. The plug-in end is a female plug. The plug-in end is provided with a power connection hole. A power connection element is provided inside the power connection hole. A power cord 5 for connecting and supplying power to the power connection element is provided inside the wrapping portion 4.

[0028] Furthermore, the rear end of the plug portion 3 is integrally formed with two mounting portions 31, which are respectively connected to the first driving member 1 and the second driving member 2. One end of each mounting portion 31 protrudes outside the wrapping portion 4 and is provided with a pivot hole 32. The first driving member 1 and the second driving member 2 are both integrally formed with a pivot portion 101 that can be rotatably fitted in the pivot hole 32. The diameter of the pivot portion 101 is the same as or substantially the same as the diameter of the pivot hole 32. Thus, after the pivot portion 101 is fitted in the pivot hole 32, the first driving member 1 and the second driving member 2 rotate more smoothly and steadily. In addition, the pivot portion 101 is integrally formed on both the first driving member 1 and the second driving member 2, resulting in a simple and stable structure.

[0029] Furthermore, the first driving member 1 is provided with a first arc-shaped tooth 11, and the second driving member 2 is provided with a second arc-shaped tooth 21 that meshes with the first arc-shaped tooth 11. The first driving member 1 and the second driving member 2 move synchronously based on the meshing transmission of the first arc-shaped tooth 11 and the second arc-shaped tooth 21, so that the first driving member 1 and the second driving member 2 can move synchronously when the user operates.

[0030] In this embodiment, a side inlet 33 is provided on one side of the mounting part 31 for the rotating shaft part 101 to be inserted into the rotating shaft hole 32. The side inlet 33 is located on the front side of the mounting part 31 and is arranged to penetrate and communicate with the rotating shaft hole 32 radially. The inlet width of the side inlet 33 gradually decreases from front to back. The minimum width of the side inlet 33 is smaller than the diameter of the rotating shaft hole 32. When the rotating shaft part 101 is installed, it can be directly squeezed into the rotating shaft hole 32 through the side inlet 33, which is simple and convenient. Since the minimum width of the side inlet 33 is smaller than the diameter of the rotating shaft hole 32, the rotating shaft part 101 is not easy to fall out after being inserted into the rotating shaft hole 32, thereby ensuring the installation stability of the first driving member 1 and the second driving member 2. In addition, the side inlet 33 is located on the front side of the mounting part 31, so that during the process of the first driving member 1 and the second driving member 2 rotating and pushing against the socket 100 at the front end of the plug body, the pivot part 101 is not easy to come out of the pivot hole 32, making the installation of the first driving member 1 and the second driving member 2 more stable.

[0031] In this embodiment, both the first driving member 1 and the second driving member 2 include a handle portion 102 and an upper linkage portion 103 and a lower linkage portion 104 integrally formed and connected to the front end of the handle portion 102. The front end of the upper linkage portion 103 is provided with an upper pushing portion 1031, and the front end of the lower linkage portion 104 is provided with a lower pushing portion 1041. The upper and lower ends of the rotating shaft portion 101 are integrally formed and connected to the upper linkage portion 103 and the lower linkage portion 104, respectively. Further, the bottom of the upper pushing portion 1031 extends downward and protrudes with a pushing reinforcement portion 1032. The front end face of the pushing reinforcement portion 1032 is flush with the front end face of the upper pushing portion 1031. The upper part of the front end of the wrapping portion 4 is provided with a pushing receiving groove 401 for accommodating the pushing reinforcement portion 1032. The pushing reinforcement portion 1032 can work together with the upper pushing portion 1031 to push against the socket 100, ensuring the quality of plug removal.

[0032] In this embodiment, the upper linkage part 103 and the lower linkage part 104 are respectively covered on the upper and lower parts of the plug body. The upper linkage part 103 and the lower linkage part 104 of the first driving member 1 are integrally formed with the first arc-shaped tooth part 11, and the upper linkage part 103 and the lower linkage part 104 of the second driving member 2 are integrally formed with the second arc-shaped tooth part 21. Each first arc-shaped tooth part 11 engages with one second arc-shaped tooth part 21. Through the above structural arrangement, the upper and lower ends of the first driving member 1 and the second driving member 2 move synchronously, so that the upper linkage part 103 and the lower linkage part 104 are simultaneously subjected to force, which solves the problem of deflection torque hindering separation during separation, and makes it easy and balanced to pull out the plug.

[0033] In this embodiment, a drive mating groove for inserting the mounting part 31 is formed between the upper linkage part 103 and the lower linkage part 104, and the rotating shaft part 101 is located in the drive mating groove. By inserting the mounting part 31 into the drive mating groove, the mounting part 31, the upper linkage part 103 and the lower linkage part 104 can be positioned vertically relative to each other, ensuring the installation quality of the first driving component 1 and the second driving component 2.

[0034] In this embodiment, to improve the quality of the plug portion 3 and the mounting portion 31 being partially wrapped and fixed by the wrapping portion 4, a first filling groove 34 is provided on the rear end face of the plug portion 3, and a plurality of first filling holes 35 communicating with the first filling groove 34 are provided on the outer rear end face of the plug portion 3. A second filling groove 36 is provided at one end of the mounting portion 31 facing another mounting portion 31. The wrapping portion 4 is at least partially filled in the first filling groove 34, the first filling holes 35 and the second filling groove 36, thereby enhancing the combined quality between the plug portion 3, the mounting portion 31 and the wrapping portion 4.

[0035] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
