Description

Technical Field

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

[0002] A power plug is an electrical interface device that connects electrical equipment to a power source. It is used to transmit electrical energy from the power source to the electrical equipment to ensure the normal operation of the equipment. It is widely used in household appliances, industrial equipment, and special environments. Three-phase power plugs are also a type of power plug. However, when three-phase power plugs are actually used with a computer case for power connection, the plug may become loose and fall off due to the frequent movement of the computer case. This can lead to a sudden power outage of the computer case and unnecessary losses, making it less practical.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN201822210797.4, application date 2018-12-26), a computer chassis power plug anti-detachment device, when there is a sign of detachment, the anti-detachment tip drives the L-rod to rotate slightly, and then the upper part of the L-rod groove restricts the rotation of the L-rod. In this way, the anti-detachment tip has the function of preventing the plug from coming off. The structure is simple, and the entire anti-detachment device can be made into a detachable structure through the upper part of the L-rod groove and can be embedded into the plug as a whole. Although the prior art can achieve anti-detachment treatment of the power plug, when the plug is unplugged after use, it will be exposed to the outside world. However, the plug does not have a waterproof and dustproof mechanism to protect it from water and dust. This will cause the plug to come into contact with moisture in the air, which will affect subsequent use and is very dangerous. Its practicality is poor. Therefore, a waterproof three-phase power plug has been proposed to solve the above problems well. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof three-phase power plug to solve the problem mentioned in the background art that, when plugs on the market are unplugged after use, they are exposed to the outside world, but the plugs do not have waterproof and dustproof mechanisms to protect them from water and dust. This can cause the plugs to come into contact with moisture in the air, affecting their subsequent use and posing a great danger and poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof three-phase power plug, comprising a plug body and a mounting plate disposed above the plug body. A protective plate is rotatably mounted on the left side of the mounting plate, and the plug body is correspondingly mounted on the inner side of the protective plate. A sealing gasket is disposed on the right side of the protective plate, and the plug body is attached to the outer side of the sealing gasket. Two limiting blocks are slidably mounted inside the mounting plate, and the outer ends of the two limiting blocks are engaged with limiting grooves. Two limiting grooves are formed inside the plug body.

[0006] Preferably, the output end of the protective plate is connected to one end of a torsion spring, and the other end of the torsion spring is connected to a mounting plate.

[0007] Preferably, the mounting plate and the protective plate form a right angle shape.

[0008] Preferably, the mounting plate has symmetrically arranged return springs inside, and the side of the two return springs away from the mounting plate is connected to a limit block.

[0009] Preferably, two compression springs are connected above the mounting plate, and levers are connected to the side of the two compression springs away from the mounting plate, wherein the two levers are symmetrically slidably mounted on the upper surface of the mounting plate.

[0010] Preferably, the two levers are connected to pull ropes on the side away from the mounting plate, and the two pull ropes are connected to limit blocks via guide wheels, and dustproof pads are connected to the opposite sides of the two levers.

[0011] Preferably, a top plate is slidably mounted inside the plug body via two storage springs, and a mounting plate is attached to the top of the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A protective plate is provided. An installation plate is installed on the top of the plug body, and a protective plate is installed on the outside of the installation plate. The plug body can be sealed and waterproofed by the sealing gasket set on the inside of the protective plate, so as to avoid moisture, dust and impurities in the outside world from sticking to the surface of the plug body and affecting the later use of plugging in. When using the plug body to plug in, you only need to flip the protective plate to drive the sealing gasket to flip, so that the plug body can be plugged in for convenient use, which is more practical.

[0014] (2) Furthermore, by using the installation plate connected to the output end of the protective plate by a torsion spring, the protective plate can be flipped and swung by the elastic force of the torsion spring itself. This makes it convenient for the plug body to be pulled out. The protective plate will then use the elastic force of the torsion spring to drive the sealing gasket to seal the plug body for dust and water protection, thus improving the protective effect of the plug body.

[0015] (3) Setting limit blocks: Two limit blocks are slidably installed inside the mounting plate by means of a reset spring. When the protective plate is quickly positioned and installed, the mounting plate is simply pressed and moved into the inside of the plug body. At this time, the two inclined limit blocks will retract and move by the squeezing of the plug body. Then, the two reset springs will automatically spring the two limit blocks into the limit groove, thereby limiting and fixing the position of the mounting plate after installation, avoiding the phenomenon of loosening and falling off during the use of the protective plate later, and improving stability.

[0016] (4) Furthermore, when it is necessary to disassemble and replace the protective plate, simply pull the two levers to drive the two pull ropes through the guide wheel to drive the two limit blocks to retract and move, so that the plug body is separated from the mounting plate. At this time, the mounting plate can be taken out from the plug body, so as to realize the quick disassembly and replacement of the protective plate, which is more time-saving and labor-saving.

[0017] (5) A top plate is provided. The top plate is slidably installed inside the plug body by two energy storage springs. Then, a mounting plate is correspondingly installed above the top plate. During the process of disassembling and replacing the mounting plate, the two energy storage springs, after being squeezed and stored, will use their own elasticity to drive the top plate to push the mounting plate out to the outside of the plug body, so as to realize the auxiliary disassembly and replacement of the mounting plate, making the operation more time-saving and labor-saving.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides the following technical solution: a waterproof three-phase power plug.

[0028] Example 1: To address the problem that existing plug bodies 1 are exposed to the outside environment after being unplugged, but the plug body 1 does not have a waterproof and dustproof mechanism to prevent the plug from coming into contact with moisture in the air, which affects subsequent use and is very dangerous and impractical, the following invention is disclosed: a plug body 1 and a mounting plate 2 set above the plug body 1. A protective plate 3 is rotatably mounted on the left side of the mounting plate 2, and the plug body 1 is corresponding to the inner side of the protective plate 3. A sealing gasket 4 is set on the right side of the protective plate 3, and the plug body 1 is attached to the outer side of the sealing gasket 4. Two limiting blocks 10 are slidably installed inside the mounting plate 2, and the outer ends of the two limiting blocks 10 are engaged with limiting grooves 12. Two limiting grooves 12 are opened inside the plug body 1.

[0029] The output end of the protective plate 3 is connected to one end of the torsion spring 9, and the other end of the torsion spring 9 is connected to the mounting plate 2. The mounting plate 2 and the protective plate 3 form a right angle shape. The mounting plate 2 is symmetrically provided with reset springs 11, and the two reset springs 11 are connected to the limit block 10 on the side away from the mounting plate 2.

[0030] like Figures 1-4 As shown, when the plug body 1 is unplugged from the chassis and the power-on use is finished, the torsion spring 9 will use its own elasticity to flip and reset the position of the flipped protective plate 3. At this time, the protective plate 3 will drive the sealing gasket 4 to seal and protect the plug body 1, preventing external moisture or dust impurities from sticking to the surface of the plug body 1 and affecting the subsequent power-on use, thus improving the safety of the plug body 1. When using the plug body 1 for power-on use, simply flip the protective plate 3 to flip the sealing gasket 4 to easily plug the plug body 1 for power-on use, which is very time-saving and labor-saving.

[0031] Example 2 differs from Example 1 in that it allows for quick disassembly and replacement of the protective plate 3, saving considerable time and effort. The following is disclosed:

[0032] Two compression springs 7 are connected to the top of the mounting plate 2, and levers 5 are connected to the side of the two compression springs 7 away from the mounting plate 2. The two levers 5 are symmetrically slidably mounted on the upper surface of the mounting plate 2. Pull ropes 6 are connected to the side of the two levers 5 away from the mounting plate 2, and the two pull ropes 6 are connected to limit blocks 10 through guide wheels. Dustproof pads 8 are connected to the opposite sides of the two levers 5. The top plate 13 is slidably mounted inside the plug body 1 through two storage springs 14, and the mounting plate 2 is attached to the top of the top plate 13.

[0033] like Figures 1-7 As shown, when positioning and installing the mounting plate 2, simply place the mounting plate 2 on the plug body 1 and press it down. At this time, the two inclined limiting blocks 10 will retract and move under the pressure of the plug body 1, causing the two limiting blocks 10 to retract and move into the interior of the mounting plate 2. Then, the two return springs 11 will automatically spring the two limiting blocks 10 into the interior of the limiting groove 12, thereby limiting and fixing the position of the mounting plate 2 after installation, preventing the protective plate 3 from loosening and falling off during later use, and improving stability.

[0034] When the protective plate 3 needs to be disassembled and replaced, simply press the two levers 5 to retract and move them through the compression springs 7. Then, the two retracting levers 5 will drive the two pull ropes 6 to retract and move through the guide wheels to drive the two limit blocks 10, so that the plug body 1 is separated from the mounting plate 2. At this time, the two compression and storage springs 14 will elastically reset the position of the top plate 13 after compression and descent. The mounting plate 2 can then be pushed out to the outside of the plug body 1 through the top plate 13, so as to realize the auxiliary disassembly and replacement of the mounting plate 2, making the operation more time-saving and labor-saving.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
