Description

Technical Field

[0001] This utility model relates to the technical field of electrical accessories, and in particular to a power cord assembly structure and an electric water heater using the same. Background Technology

[0002] Currently, when assembling electrical appliances, such as electric water heaters, one end of the power cord needs to connect to the drive circuit board inside the casing, while the other end has a plug for connecting to a socket. Generally, the power cord needs to be securely connected to the casing to prevent damage to the internal structure, such as the drive circuit board, when the power cord is pulled from the outside. Currently, a fastener is typically used to secure the power cord. Pliers are used to clamp and tighten the fastener, then it is inserted into the casing through the power cord hole. The pliers are then released, thus locking the fastener to the outside of the power cord and leaving it protruding from the casing. Inside the casing, pulling the power cord from the outside won't damage the internal drive power board and other structures. However, this method is cumbersome and difficult. It requires squeezing the pliers tightly and aligning them with the holes in the casing. If the pliers aren't tight enough or the holes aren't aligned, the cord won't fit inside, requiring repeated attempts. This cumbersome and difficult process results in high labor costs, low assembly efficiency, and the fasteners can detach from the power cord, causing it to loosen. Pulling the power cord will then damage the drive circuit board and other internal structures. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to propose a power cord assembly structure and an electric water heater using the same, thereby solving the problems of cumbersome and difficult assembly operations, unstable structure, high labor costs, and low work efficiency in the existing technology.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A power cord assembly structure includes a power cord body and an assembly, wherein the assembly is disposed in the middle of the power cord body, and the power cord body and the assembly are integrally formed.

[0006] The assembly includes a limiting part, a mounting part, and a fixing part. The limiting part and the fixing part are respectively disposed at both ends of the mounting part. At least one end of the limiting part has a limiting protrusion protruding outward along the edge of the mounting part. The cross-sectional area of ​​the fixing part is larger than the cross-sectional area of ​​the mounting part.

[0007] Preferably, the limiting protrusion has a chamfered edge facing the mounting portion.

[0008] Preferably, there are two limiting protrusions, which are located at both ends of the limiting part, and the limiting part and the limiting protrusions form an integral structure with a rectangular cross-section.

[0009] Preferably, a mounting protrusion is provided on the side of the fixing part away from the mounting part.

[0010] Preferably, the surface of the mounting protrusion is provided with a plurality of anti-slip grooves, which are arranged on the outer wall of the mounting protrusion.

[0011] Preferably, a plurality of baffles are provided on the side of the fixing part away from the mounting part, and the baffles are vertically disposed on the fixing part.

[0012] Preferably, the fixing part has a positioning protrusion on the side facing the mounting part.

[0013] Preferably, an indicator block is provided on the side of the fixing part facing away from the mounting part, and the indicator block is located at the projection position of the positioning protrusion toward the fixing part.

[0014] This application also proposes an electric water heater that uses the aforementioned power cord assembly structure and includes a water heater housing. The water heater housing is provided with a mounting hole, the shape of which is consistent with the cross-sectional shape of the limiting part. The assembly is installed in the mounting hole, the mounting hole is sleeved on the outer periphery of the mounting part, and the limiting part and the fixing part are respectively located on both sides of the mounting hole.

[0015] Preferably, a positioning hole is also provided on one side of the mounting hole, and the positioning protrusion can be installed and inserted into the positioning hole.

[0016] One of the above technical solutions has the following advantages or beneficial effects:

[0017] 1. A power cord assembly structure and an electric water heater using the same, wherein the power cord body and the assembly are integrally formed, the structure is more stable and reliable, and the assembly will not fall off the power cord body.

[0018] 2. During assembly, insert the limiting part into the housing through the hole. The hole of the housing fits around the outer periphery of the mounting part. Then rotate the assembly to complete the installation. After installation, the other side of the hole of the housing is blocked by the limiting protrusion and the inner side of the fixing part and cannot move. Therefore, no matter whether the power cord body is pulled from the inside or outside, the assembly cannot be moved, thus protecting the drive circuit board and other structures. The assembly is convenient, which can not only improve work efficiency, but also effectively reduce labor costs. Attached Figure Description

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is combined Figures 1 to 3 This utility model describes a power cord assembly structure, including a power cord body 1 and an assembly 2, wherein the assembly 2 is disposed in the middle of the power cord body 1, and the power cord body 1 and the assembly 2 are integrally formed.

[0029] The assembly 2 includes a limiting part 21, a mounting part 22, and a fixing part 23. The limiting part 21 and the fixing part 23 are respectively disposed at both ends of the mounting part 22. At least one end of the limiting part 21 protrudes outward along the edge of the mounting part 22 and is provided with a limiting protrusion 221. The cross-sectional area of ​​the fixing part 23 is larger than the cross-sectional area of ​​the mounting part 22.

[0030] Specifically, in assembling electrical appliances, such as electric water heaters, one end of the power cord needs to connect to the drive circuit board inside the casing, while the other end has a plug for connecting to a socket. Generally, the power cord needs to be secured to the casing to prevent damage to the internal drive circuit board and other structures when the power cord is pulled from the outside. Currently, a fastener is typically used on the outside of the power cord. Pliers are used to clamp and tighten the fastener before it is inserted into the casing through the power cord hole. Then the pliers are released, locking the fastener outside the power cord but remaining inside the casing. Pulling the power cord from the outside prevents damage to the internal drive circuit board and other structures. However, this method is cumbersome and difficult. It requires not only squeezing the pliers tightly but also aligning them with the hole in the casing. Insufficient clamping or misalignment will prevent insertion, requiring repetition. This cumbersome and difficult process results in high labor costs and low assembly efficiency. In this embodiment, the power cord body 1 and the assembly 2 are integrally formed and do not require assembly. The outer shell of the appliance is provided with a hole of the same shape as the limiting part 21. During assembly, the limiting part 21 is inserted into the outer shell through the hole, and the hole of the outer shell fits around the outer periphery of the mounting part 22. Then, the assembly 2 is rotated so that the limiting protrusion 221 of the limiting part 21 leaves the position of the hole, so that the outer shell is between the limiting protrusion 221 and the fixing part 23. The cross-sectional area of ​​the fixing part 23 is larger than the cross-sectional area of ​​the mounting part 22. After installation, the other side of the hole of the outer shell is blocked and limited by the limiting protrusion 221 and the inner side of the fixing part 23, and cannot move. Therefore, no matter whether the power cord body 1 is pulled from the inside or the outside, the assembly 2 cannot be pulled, thereby protecting the drive circuit board and other structures. The structure of this utility model is easy to assemble, which can not only improve work efficiency, but also effectively reduce labor costs. The structure is also more stable and reliable, and the assembly 2 will not fall off the power cord body 1.

[0031] Furthermore, the limiting protrusion 221 has a chamfer 222 on its edge facing the mounting portion 22.

[0032] Specifically, in this embodiment, the limiting protrusion 221 is provided with a chamfer 222. During disassembly, it is necessary to rotate the assembly 2, align the limiting protrusion 221 with the hole in the electrical housing, and then pull it out. The chamfer 222 has a guiding function, which helps the limiting part 21 to be pulled out of the hole, making the operation more convenient and helping to improve the efficiency of the assembly work.

[0033] Furthermore, there are two limiting protrusions 221, which are located at both ends of the limiting part 21, and the limiting part 21 and the limiting protrusions 221 form an integral structure with a rectangular cross-section.

[0034] Specifically, in this embodiment, two limiting protrusions 221 are provided, which can limit the assembly from both ends of the limiting part 21, making the assembled power cord structure more stable and reliable, and further preventing the assembly 2 from falling out of the hole in the outer shell.

[0035] Furthermore, a mounting protrusion 231 is provided on the side of the fixing part 23 away from the mounting part 22.

[0036] Specifically, in this embodiment, the function of the mounting protrusion 231 is to provide a grip for the installer during installation. Since the outer end face of the fixing part 23 is relatively flat, it is necessary to grip the assembly 2 for assembly during installation. In this embodiment, the mounting protrusion 231 is provided so that the installer can grip the mounting protrusion 231 to insert the assembly 2 into the outer shell, making the operation more convenient and helping to improve the efficiency of the assembly work.

[0037] Furthermore, the surface of the mounting protrusion 231 is provided with a plurality of anti-slip grooves 232, which are arranged on the outer wall of the mounting protrusion 231.

[0038] Specifically, in this embodiment, the surface of the mounting protrusion 231 is provided with several anti-slip grooves 232, so that the installer will not slip when gripping the mounting protrusion 231, making the assembly operation more convenient and helping to improve the efficiency of the assembly work.

[0039] Furthermore, a plurality of baffles 233 are provided on the side of the fixing part 23 away from the mounting part 22, and the baffles 233 are vertically disposed on the fixing part 23.

[0040] Specifically, in this embodiment, a plurality of baffles 233 are provided on the side of the fixing part 23 away from the mounting part 22. The function of the baffles 233 is that when it is necessary to rotate the assembly 2, the assembly 2 can be rotated by moving the baffles 233, which makes the operation more convenient and also helps to improve the efficiency of the assembly work.

[0041] Furthermore, a positioning protrusion 234 is provided on the side of the fixing part 23 facing the mounting part 22.

[0042] Specifically, in this embodiment, a positioning protrusion 234 is provided on the side of the fixing part 23 facing the mounting part 22, and a positioning hole 102 is also provided on the corresponding electrical housing. When the assembly 2 is rotated so that the limiting protrusion 221 of the limiting part 21 leaves the position of the hole, and the housing is between the limiting protrusion 221 and the fixing part 23, the positioning protrusion 234 can be inserted into the positioning hole 102 of the housing, so that the assembly 2 cannot be rotated, thus avoiding the problem of the assembly 2 falling out of the hole of the housing due to rotation.

[0043] Furthermore, an indicator block 235 is provided on the side of the fixing part 23 facing away from the mounting part 22, and the indicator block 235 is located at the projection position of the positioning protrusion 234 toward the fixing part 23.

[0044] Specifically, in this embodiment, during assembly, since the fixing part 23 blocks the position of the positioning protrusion 234, the indicator block 235 is used to show the position of the positioning protrusion 234 to the installer, so that the installer can easily know the position of the positioning protrusion 234, thereby rotating the assembly 2 to install the positioning protrusion 234 into the positioning hole 102, making the operation more convenient and also helping to improve the efficiency of the assembly work.

[0045] like Figure 4 An electric water heater is proposed, which uses the power cord assembly structure as described above, and also includes a water heater housing 100. The water heater housing 100 is provided with a mounting hole 101. The shape of the mounting hole 101 is consistent with the cross-sectional shape of the limiting part 21. The assembly 2 is installed in the mounting hole 101. The mounting hole 101 is sleeved on the outer periphery of the mounting part 22. The limiting part 21 and the fixing part 23 are respectively located on both sides of the mounting hole 101.

[0046] Specifically, this embodiment proposes an electric water heater that utilizes the power cord assembly structure of this utility model. The limiting part 21 is inserted into the water heater housing 100 through the mounting hole 101. The mounting hole 101 of the water heater housing 100 fits around the outer periphery of the mounting part 22. Then, the assembly 2 is rotated so that the limiting protrusion 221 of the limiting part 21 moves away from the mounting hole 101, placing the water heater housing 100 between the limiting protrusion 221 and the fixing part 23. The cross-sectional area of ​​the fixing part 23 is larger than that of the mounting part 22. After installation, the other side of the mounting hole 101 of the water heater housing 100 is blocked and immobilized by the limiting protrusion 221 and the inner side of the fixing part 23. Therefore, regardless of whether the power cord body 1 is pulled from the inside or outside, the assembly 2 cannot be moved, thus protecting the drive circuit board and other structures. This makes the assembly of the electric water heater convenient, improving work efficiency and effectively reducing labor costs. The structure is also more stable and reliable, and the assembly 2 will not fall off the power cord body 1.

[0047] Furthermore, a positioning hole 102 is provided on one side of the mounting hole 101, and the positioning protrusion 234 can be installed and inserted into the positioning hole 102.

[0048] Specifically, in this embodiment, a positioning protrusion 234 is provided on the side of the fixing part 23 facing the mounting part 22, and a positioning hole 102 is also provided on the corresponding water heater housing 100. Rotating the assembly 2 causes the limiting protrusion 221 of the limiting part 21 to leave the position of the hole, so that the water heater housing 100 is locked when it is between the limiting protrusion 221 and the fixing part 23. At the same time, the positioning protrusion 234 can be inserted into the positioning hole 102 of the water heater housing 100, so that the assembly 2 cannot be rotated, thus avoiding the problem of the assembly 2 falling out of the hole of the water heater housing 100 due to rotation.
