Technical Field

[0001] The present invention relates to a multi-purpose power strip that can prevent splashing water and mud and pass through the corner of a wall. Background Art

[0002] A power strip is an indispensable electrical device in people's daily life. It is mainly used to expand the number of jacks and extend the power cord for electrical appliances with insufficiently long power cords.

[0003] However, the jacks of existing power strips are basically open, without waterproof and dustproof measures. When used outdoors, in case of rainy weather, rainwater easily enters the jacks of the power strip, causing electric leakage incidents and bringing great potential safety hazards to people's lives; when used in a construction environment with a lot of dust, the sludge formed by the mixture of dust and sewage easily enters the jacks of the power strip, or the raised dust accumulates and blocks the jacks of the power strip, which brings inconvenience to the normal and safe use of the power strip.

[0004] Therefore, there is an urgent need to provide a multi-purpose power strip that can prevent splashing water and mud and pass through the corner of a wall to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-purpose power strip that can prevent splashing water and mud and pass through the corner of a wall. The multi-purpose power strip has a simple structure, is convenient to assemble and use, has good waterproof, dustproof, mud-proof and anti-dragging and falling-off effects, has a long service life, and can ensure safety and reliability during use.

[0006] To achieve the above purpose, the present invention provides a multi-purpose power strip that can prevent splashing water and mud and pass through the corner of a wall, including a shuttle-shaped outer shell with an open top part, a shuttle-shaped inner shell installed inside the outer shell, and a sliding cover that can slidably close the open top part of the outer shell; wherein,

[0007] A socket is detachably installed inside the inner shell, and the power supply cord of the socket passes through the inner shell and extends outward from one end of the outer shell; a cavity for accommodating the power cord and the power plug of the electrical device is also formed inside the shuttle-shaped inner shell, and the power cord of the electrical device inserted into the socket passes through the inner shell and extends outward from the other end of the outer shell.

[0008] A waterproof rubber sleeve is formed at the end of the outer shell close to the power supply cord, a drain hole is opened at the end of the outer shell close to the power cord of the electrical device, and a drain groove is formed at the edge of the inner shell close to the sliding cover. The drain groove and the drain hole are communicated through a drain gap formed between the outer shell and the inner shell.

[0009] Preferably, a snap claw and a snap head that can be snap-fitted and assembled and fixed to each other are respectively formed at one end of the sliding cover and the outer shell close to the drain hole.

[0010] Preferably, the surface shapes of both ends of the housing and the end of the sliding cover fixed by the buckle are rounded.

[0011] Preferably, the edge of the inner shell is turned outward to form a sliding lip plate, and the sliding cover can be slid along the sliding lip plate and assembled and fixed by snapping.

[0012] Preferably, the waterproof rubber sleeve is a conical rubber sleeve made of flexible material.

[0013] Preferably, the multi-purpose extension strip that is splash-proof and mud-proof and can pass through corners also includes an inner cover, which is arranged at the connection between the power cord and the power plug, and an arc-shaped guide groove is formed on the bottom end surface of the inner cover, so that the power cord extends along the arc-shaped guide groove at the bottom and passes through the outer shell after entering the inner cover.

[0014] Preferably, the inner cover is fixed by matching the undercut claw groove and the limiting protrusion on the inner shell through the undercut claw and the limiting notch.

[0015] Preferably, the outer shell and the inner shell are detachably connected via bolts, and the socket and the inner shell are detachably connected via bolts.

[0016] According to the above technical scheme, the main body of the present invention is composed of a shuttle-shaped outer shell with an open top portion, a shuttle-shaped inner shell installed inside the outer shell, and a sliding cover that can slide to close the open top portion of the outer shell; at the same time, a socket is detachably installed inside the inner shell, and the power supply line of the socket passes through the inner shell and extends outward from one end of the outer shell; a cavity for accommodating the power supply line and the power plug of the electrical device is also formed inside the shuttle-shaped inner shell, and the power supply line inserted into the socket passes through the inner shell and extends outward from the other end of the outer shell. In this way, when in use, the socket is connected to the circuit, the sliding cover is slid open, the socket is exposed, and the power plug of the electrical device is inserted into the socket to connect the power supply to use the electrical appliance. At this time, the sliding cover is slid closed again to seal the entire extension board, which can achieve a good waterproof and dustproof effect, and even sludge formed in the use environment is difficult to easily enter the extension board. Furthermore, a waterproof rubber sleeve is formed on the end of the outer shell near the power supply line, a drainage hole is opened on the end of the outer shell near the power supply line, and a drainage groove is formed on the edge of the inner shell near the sliding cover, and the drainage groove and the drainage hole are connected through the drainage gap formed between the outer shell and the inner shell. With this structure, when the extension board is hung up for use, the waterproof rubber sleeve faces upward, and the good waterproof effect can effectively prevent outdoor rain or water droplets generated in the indoor use environment from entering the extension board from the upper end, preventing the socket from leaking or short-circuiting due to water ingress. Most of the water droplets will flow down along the outer wall of the outer shell. Even if some water droplets enter the interior through the gap between the sliding cover and the outer shell, they will enter the drainage gap along the drainage groove, and then be discharged from the extension board through the drainage gap through the drainage hole, without affecting the dry use environment in the inner shell, and it is waterproof and safe.

[0035] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] In the present invention, unless otherwise stated, the orientation terms included in terms such as "upper, lower, inner, outer" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation to the term.

[0037] See Figure 1 , the present invention provides a multi - purpose extension cord that can prevent splashing water and mud and can pass through the corner, including a shuttle - shaped outer shell 1 with an open top part, a shuttle - shaped inner shell 2 installed inside the outer shell 1, and a sliding cover 3 that can slidably close the open top part of the outer shell 1; wherein,

[0038] A socket 4 is detachably installed inside the inner shell 2, and the power supply cord 5 of the socket 4 passes through the inner shell 2 and extends outward from one end of the outer shell 1; a cavity for accommodating the power cord 6 of the electrical device and the electrical plug is also formed inside the shuttle - shaped inner shell 2, and the power cord 6 of the electrical device inserted into the socket 4 passes through the inner shell 2 and extends outward from the other end of the outer shell 1;

[0039] A waterproof rubber sleeve 7 is formed at the end of the outer shell 1 near the power supply cord 5, a drain hole 8 is opened at the end of the outer shell 1 near the power cord 6 of the electrical device, and a drain groove 9 is formed at the edge of the inner shell 2 near the sliding cover 3. The drain groove 9 and the drain hole 8 are communicated through a drain gap 10 formed between the outer shell 1 and the inner shell 2.

[0040] Through the above technical solutions, the main body of the multi - purpose extension cord that can prevent splashing water and mud and can pass through the corner is composed of a shuttle - shaped outer shell 1 with an open top part, a shuttle - shaped inner shell 2 installed inside the outer shell 1, and a sliding cover 3 that can slidably close the open top part of the outer shell 1; at the same time, a socket 4 is detachably installed inside the inner shell 2, and the power supply cord 5 of the socket 4 passes through the inner shell 2 and extends outward from one end of the outer shell 1; a cavity for accommodating the power cord 6 of the electrical device and the electrical plug is also formed inside the shuttle - shaped inner shell 2, and the power cord 6 of the electrical device inserted into the socket 4 passes through the inner shell 2 and extends outward from the other end of the outer shell 1. In this way, when in use, the socket 4 is connected to the circuit, the sliding cover 3 is slid open, the socket 4 is exposed, and the electrical plug of the electrical device is inserted into the socket 4 to connect the power supply and use the electrical appliance. At this time, the sliding cover 3 is slid closed again to enclose the entire extension cord, which can achieve a good waterproof and dust - proof effect, and even the sludge formed in the use environment is difficult to easily enter the extension cord. Further, as Figure 2As shown, a waterproof rubber sleeve 7 is formed at the end of the outer shell 1 near the power supply cord 5, and a drain hole 8 is provided at the end of the outer shell 1 near the power consumption cord 6. Moreover, a drain groove 9 is formed at the edge of the inner shell 2 near the sliding cover 3, and the drain groove 9 is communicated with the drain hole 8 through a drain gap 10 formed between the outer shell 1 and the inner shell 2. With this structure, when the power strip is used in a suspended state, the waterproof rubber sleeve 7 faces upward, and the good waterproof effect can effectively prevent outdoor rainwater or water droplets generated in the indoor use environment from entering the power strip from the upper end, preventing the socket 4 from getting waterlogged and causing electric leakage or short circuit. Most of the water droplets will flow down along the outer wall of the outer shell 1. Even if some water droplets enter the interior through the gap between the sliding cover 3 and the outer shell 1, they will flow into the drain gap 10 along the drain groove 9, and then be discharged outside the power strip through the drain hole 8 from the drain gap 10, without affecting the dry use environment inside the inner shell 2, ensuring waterproof safety.

[0041] In this embodiment, in order to facilitate the quick and convenient assembly and disassembly between the sliding cover 3 and the outer shell 1, preferably, a snap claw and a snap head that can be snap-fitted and assembled and fixed to each other are respectively formed at one end of the sliding cover 3 and the outer shell 1 near the drain hole 8.

[0042] During the actual use of the multi-purpose power strip with splash and mud protection and corner-passing ability, overall dragging often occurs. When passing through a door frame or a corner during dragging, the protruding and sharp door frame or corner is very likely to block the power strip, hindering the user from continuing to drag forward with force, and the user needs to go back to the door frame or corner to deal with it, wasting precious time. Therefore, in order to avoid the above situation, preferably, the surface shapes of both ends of the outer shell 1 and the end of the sliding cover 3 where they are snap-fixed are rounded. In this way, when passing through a door frame or a corner during the pulling process, its smooth outer surface is not easily blocked, and a little force can achieve smooth traction and pulling, facilitating wiring and saving time and effort.

[0043] In addition, in order to make the sliding of the sliding cover 3 more smooth and the sliding structure more stable and not easily fall off, preferably, a sliding lip plate 11 is formed by turning up the edge of the inner shell 2, and the sliding cover 3 can slide and cover along the sliding lip plate 11 and be snap-fitted and assembled and fixed.

[0044] In addition to having good waterproof performance, in order for the above-mentioned waterproof rubber sleeve 7 to also have buffering, anti-collision, and smooth effects at the same time, preferably, the waterproof rubber sleeve 7 is a conical rubber sleeve made of a flexible material.

[0045] When in use, when the multi-purpose extension cord that is splash-proof and mud-proof and can pass through corners is pulled hard to shift, the power cord 6 connected to the power plug will be subjected to a certain pulling force. If this pulling force is all applied to the power cord 6, it is very easy to cause the power plug connected thereto to fall off from the socket hole. At this time, it is necessary to reopen the multi-purpose extension cord that is splash-proof and mud-proof and can pass through corners and reconnect the plug, which wastes time and is not worth the loss. In order to avoid the above situation, the multi-purpose extension cord that is splash-proof and mud-proof and can pass through corners preferably also includes an inner cover 12, which is arranged at the connection between the power cord 6 and the power plug, and an arc guide groove 13 is formed on the bottom end surface of the inner cover 12, so that the power cord 6 enters the inner cover 12 and extends along the arc guide groove 13 at the bottom and passes through the outer shell 1. In this way, when the power cord 6 outside the multi-purpose extension board that is splash-proof and mud-proof and can pass through corners is pulled, the power cord 6 that has been constrained to bend will directly exert pressure on the surface of the inner cover 12, and the force directly acting on the power plug will be greatly reduced, thereby ensuring the connection of the power circuit. At the same time, the arc-shaped guide groove 13 can also regulate the direction of the power cord 6 to prevent the power cord 6 from being twisted or folded after long-term use, thereby ensuring its service life.

[0046] Furthermore, in order to realize quick assembly and disassembly between the inner cover 12 and the inner shell 2, preferably, the inner cover 12 is fixed by the undercut claw 14 and the limiting notch 15 in cooperation with the undercut claw groove and the limiting protrusion on the inner shell 2. In this way, the relative position between the inner cover 12 and the inner shell 2 is more stable and the overall structure is more compact through the combination of the undercut claw 14 and the limiting notch 15.

[0047] In addition, the detachable connection in the present embodiment can be any connection method commonly used in the art to achieve quick fixing and disassembly functions. However, from the perspective of facilitating operation and controlling product production costs, preferably, the outer shell 1 and the inner shell 2 are detachably connected by bolts, and the socket 4 and the inner shell 2 are detachably connected by bolts.

[0048] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0050] In addition, any combination can be made among various different embodiments of the present invention, as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
