Description

Technical Field

[0001] This utility model relates to the field of power adapters, and more specifically, to a high-safety power adapter with waterproof and moisture-proof features. Background Technology

[0002] A power adapter, also known as an external power supply, is a voltage conversion device for small portable electronic devices and appliances. It is commonly found in small electronic products such as mobile phones, LCD monitors, and laptops.

[0003] Chinese Patent Publication No. CN219917690U discloses a power adapter. When the distance between the power supply and the electronic device is short, the plug assembly is connected directly to the power supply, reducing the space occupied by excess wires. When the distance is long, the input cable is plugged into the input interface for electrical connection, and then connected to the power supply. This extends the connection distance between the power supply and the electronic device, enabling longer-distance movement and operation of the electronic device. It minimizes the space occupied by the power adapter's connection cable while ensuring the electronic device and power supply are close together, and allows charging even when the electronic device and power supply are far apart.

[0004] In the above solution, the detachable connection parts of the main structure and plug structure, the parts through which the output line passes through the housing, the movable gaps between the plug assembly and the housing, and the input interface lack effective sealing and protection structures. In humid environments, when water vapor condenses, or when accidentally exposed to liquid, moisture can easily penetrate into the housing through these gaps and come into direct contact with the electronic control components, potentially causing safety hazards such as short circuits and leakage. At the same time, it will accelerate the corrosion and aging of electronic components, leading to a shortened product lifespan and affecting the reliability and safety of use. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-safety power adapter with waterproof and moisture-proof features. It achieves sealing protection of the power adapter body through a flip-up waterproof sealing cover and connecting strip. The sealing ring at the front end of the waterproof sealing cover, when closed, elastically deforms to fill the gap between itself and the power adapter body, effectively preventing moisture, dust, and other impurities from entering the interior through detachable connections between the main body and plug structure, and movable gaps between the plug assembly and the outer shell. This avoids direct contact between the electronic components and moisture, reduces the risk of short circuits and leakage, minimizes corrosion and aging of electronic components, extends product lifespan, and improves reliability and safety.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A high-safety power adapter with waterproof and moisture-proof features includes a power adapter body, characterized in that: a first rectangular strip is provided on both sides of the power adapter body; a waterproof sealing cap is fitted at the rear end of the power adapter body, the inner diameter of the waterproof sealing cap being adapted to the diameter of the power adapter body; a second rectangular strip is provided on both sides of the waterproof sealing cap; a connecting strip is fixedly installed at the front end of the second rectangular strip, the connecting strip being located on the outer surface of the first rectangular strip; a rectangular cavity is provided inside the first rectangular strip; a rectangular track is provided on the outer side of the first rectangular strip, communicating with the rectangular cavity; the width of the rectangular track is smaller than the inner width of the rectangular cavity; and fixing components are installed inside the rectangular cavity and at the front end of the connecting strip.

[0010] Furthermore, both of the aforementioned fasteners include a nut and an abutment plate. The nut is installed at the front end of the connecting strip via a threaded connection, and the abutment plate is installed inside the nut via a fixed connection. The abutment plate is located inside a rectangular cavity, and the diameter of the abutment plate is greater than the width of the rectangular track. Both of the aforementioned fasteners also include multiple silicone blocks, which are installed inside the abutment plate via a fixed connection.

[0011] Furthermore, a sealing ring is fixedly embedded in the front end of the waterproof sealing cover.

[0012] Furthermore, the power adapter body has a storage cavity at its front end, a cylindrical platform is fixedly installed in the middle of the storage cavity, a power plug is fixedly installed at the front end of the cylindrical platform, a power cord is fixedly installed inside the power adapter body, and the power cord is installed on the outside of the cylindrical platform by winding. An interface is fixedly installed at the end of the power cord away from the power adapter body, and a through hole is provided at the lower front end of the power adapter body, the inner diameter of the through hole being smaller than the diameter of the power cord.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can achieve the sealing protection of the power adapter body by setting a flip-up waterproof sealing cover and connecting strip. When the sealing ring at the front end of the waterproof sealing cover is closed, it fills the gap between the power adapter body through elastic deformation. This can effectively prevent moisture, dust and other impurities from entering the interior through the detachable connection parts of the main structure and plug structure, the movable gaps between the plug components and the shell, etc. This avoids direct contact between the electronic control components and moisture, reduces the risk of short circuit and leakage, reduces the corrosion and aging of electronic components, extends the product service life, and improves the reliability and safety of use.

[0016] (2) The rectangular cavity and rectangular track of the first rectangular strip cooperate with the connecting strip of the second rectangular strip. Combined with the abutment plate of the fixing part to restrict the connection strip from falling off, the nut achieves thread fastening, and the silicone block enhances the friction between the abutment plate and the inner wall of the rectangular cavity. This allows the waterproof sealing cover to be firmly connected to the power adapter body, preventing it from falling off during use. At the same time, it provides a structural basis for the installation and disassembly of the waterproof sealing cover, ensuring the reliability of the connection.

[0017] (3) The power cord can be wrapped around the outside of the cylindrical platform and stored in the storage cavity to achieve orderly organization of the power cord and avoid messy tangling; the inner diameter of the through hole is smaller than the diameter of the power cord, which can limit the power cord and allow the power cord to pass through the through hole when in use; the power plug is fixed at the front end of the cylindrical platform, which is convenient to use and can be easily wrapped and protected by a waterproof sealing cover, so that the power plug is protected when not in use, avoiding the deformation or damage of the plug pins caused by bumps and squeezing, while reducing the safety hazards caused by the exposed power plug and improving the safety and integrity of the product.

[0027] Example 1:

[0028] Please see Figure 1-4 A high-safety power adapter with waterproof and moisture-proof features includes a power adapter body 1. The power adapter body 1 has a first rectangular strip 11 on both sides, a waterproof sealing cap 2 fitted at the rear end of the power adapter body 1, the inner diameter of the waterproof sealing cap 2 matching the diameter of the power adapter body 1, a second rectangular strip 21 on both sides of the waterproof sealing cap 2, a connecting strip 22 fixedly installed at the front end of the second rectangular strip 21, the connecting strip 22 located on the outer surface of the first rectangular strip 11, a rectangular cavity 111 inside the first rectangular strip 11, a rectangular track 112 communicating with the rectangular cavity 111 on the outer side of the first rectangular strip 11, the width of the rectangular track 112 being smaller than the inner width of the rectangular cavity 111, and fixing members 6 installed inside the rectangular cavity 111 and at the front end of the connecting strip 22. The rectangular cavity 111 and rectangular track 112 of the first rectangular strip 11 cooperate with the connecting strip 22 of the second rectangular strip 21. Combined with the abutment plate 62 of the fixing member 6 to restrict the connecting strip 22 from disengaging, the nut 61 achieves threaded fastening, and the silicone block 63 enhances the friction between the abutment plate 62 and the inner wall of the rectangular cavity 111. This allows the waterproof sealing cover 2 to be firmly connected to the power adapter body 1, preventing it from falling off during use. At the same time, it provides a structural basis for the installation and disassembly of the waterproof sealing cover 2, ensuring the reliability of the connection.

[0029] Please see Figure 4Both fasteners 6 include a nut 61 and an abutment plate 62. The nut 61 is installed at the front end of the connecting strip 22 via a threaded connection. The abutment plate 62 is installed inside the nut 61 via a fixed connection. The abutment plate 62 is located inside the rectangular cavity 111, and the diameter of the abutment plate 62 is larger than the width of the rectangular track 112. Both fasteners 6 also include multiple silicone blocks 63. The silicone blocks 63 are installed inside the abutment plate 62 via a fixed connection. In use, the multiple silicone blocks 63 inside the abutment plate 62 are in close contact with the inner wall of the rectangular cavity 111 through elastic compression. This increases friction to prevent the fasteners 6 from loosening and improves the stability of the connection between the waterproof sealing cover 2 and the body 1. It also allows the silicone to buffer against slight vibrations or deformations, avoiding structural wear caused by rigid contact and extending the service life of the components.

[0030] Please see Figure 1 and Figure 3 A sealing ring 23 is fixedly embedded in the front end of the waterproof sealing cover 2. When in use, the sealing ring 23 is fixedly embedded in the front end of the waterproof sealing cover 2. When the waterproof sealing cover 2 and the power adapter body 1 are closed, the sealing ring 23 can fill the gap between them through elastic deformation, enhance the overall sealing performance, effectively prevent moisture, dust and other impurities from entering the adapter, protect the internal components, reduce the risk of short circuit and damage caused by moisture, and improve the safety and durability of the product.

[0031] The power adapter body 1 has a storage cavity 101 at its front end. A cylindrical platform 12 is fixedly installed in the center of the storage cavity 101. A power plug 3 is fixedly installed at the front end of the cylindrical platform 12. A power cord 4 is fixedly installed inside the power adapter body 1, and the power cord 4 is wound around the outside of the cylindrical platform 12. An interface 5 is fixedly installed at the end of the power cord 4 away from the power adapter body 1. A through hole 13 is provided at the lower front end of the power adapter body 1. The inner diameter of the through hole 13 is smaller than the diameter of the power cord 4. In use, the power cord 4 can be wound around the outside of the cylindrical platform 12. The power cord 4 is neatly organized within the storage cavity 101, preventing tangling and mess. The inner diameter of the through hole 13 is smaller than the diameter of the power cord 4, which limits the power cord 4 so that it can pass through the through hole 13 when in use. The power plug 3 is fixed to the front end of the cylindrical platform 12, which is convenient for use and allows the waterproof sealing cover 2 to wrap and protect it. This protects the power plug 3 when not in use, preventing the plug from being deformed or damaged by bumps or squeezing. It also reduces the safety hazards caused by the exposed power plug 3, improving the safety and integrity of the product.

[0032] The working principle of this utility model is as follows: the first rectangular strips 11 on both sides of the power adapter body 1 cooperate with the connecting strips 22 on both sides of the waterproof sealing cover 2. The connecting strips 22 are restricted from disengaging by the abutment plate 62 in the fixing member 6, and the nut 61 achieves threaded fastening. By flipping the waterproof sealing cover 2 and the connecting strips 22, the waterproof sealing cover 2 is positioned at the front or rear end of the power adapter body 1, realizing the switching between the sealed protection and open use state of the power adapter body 1. The silicone block 63 on the inner side of the abutment plate 62 makes tight contact with the inner wall of the rectangular cavity 111 through elastic compression to enhance the friction and ensure the waterproof sealing cover. 2. It is securely connected to the power adapter body 1; the sealing ring 23 at the front end of the waterproof sealing cover 2 fills the gap between the two through elastic deformation when closed, preventing moisture and dust from entering; the storage cavity 101 at the front end of the power adapter body 1 can store the power cord 4 wrapped around the outside of the cylindrical platform 12, and the through hole 13 limits the power cord 4 so that it can pass through the through hole 13 when in use. The power plug 3 at the front end of the cylindrical platform 12 can be wrapped and protected by the waterproof sealing cover 2 when not in use, so as to achieve waterproof and moisture-proof functions while ensuring the stable connection of the overall structure of the power adapter, component storage and use safety.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
