TECHNICAL FIELD

[0001] The utility model relates to power plug technical field, concretely relates to a power plug with waterproof structure. BACKGROUND

[0002] The power plug is an important accessory in the use of electrical equipment, and when used outdoors and in the wild, the waterproof of the plug connection structure needs to be ensured to avoid water vapor from entering the inside and to avoid short circuit of the connection caused by rain.

[0003] However, in actual use, the conventional waterproof power plug is usually connected and fixed by simple sleeving, which still has gaps in actual use, causing rainwater to enter, and the conventional power plug usually lacks a fixing structure in use, so that it is easy to be pulled off in outdoor use, and in rainy weather, once the connection is disconnected, the plug is easy to be waterlogged and cause leakage, resulting in safety hazards. UTILITY MODEL CONTENTS

[0004] The utility model discloses a power plug with waterproof structure, which solves the problems of lack of waterproof structure, easy waterlogging and easy to be pulled off in outdoor use.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a power plug with waterproof structure, comprising a connecting head, a connecting barrel is inserted into one end of the connecting head, a sleeving ring is arranged on the outer wall of the connecting head away from the connecting barrel, a sealing ring is fixedly connected to one end of the sleeving ring close to the connecting barrel, and a surrounding air bag is arranged on the side of the sealing ring away from the sleeving ring.

[0006] The outer wall of the connecting head is sleeved with the sealing ring and the surrounding air bag, and a plurality of connecting pieces are fixedly connected to one end of the connecting head close to the connecting barrel.

[0007] A containing groove is formed in the inner end of the connecting barrel close to the connecting head, and a plurality of sliding grooves are formed in the inner wall of the containing groove close to the connecting head.

[0008] The outer wall of the sealing ring is sleeved with a plurality of clamping blocks, and the clamping blocks and the sliding grooves are slidably connected.

[0009] Preferably, the inner end of the containing groove is provided with an insertion hole corresponding to the insertion of the connecting piece, the outer diameter of the connecting head is smaller than the inner diameter of the containing groove, and the outer diameter of the sealing ring corresponds to the inner diameter of the containing groove.

[0010] Preferably, a fixing ring is provided at one end of the surrounding airbag near the connecting cylinder. The fixing ring is fixedly connected to the outer wall of the connector, and the side of the fixing ring near the surrounding airbag is inclined towards the center of the connector.

[0011] Preferably, one end of the slide groove penetrates the inner wall edge of the receiving groove, and the internal dimensions of the slide groove correspond to the snap-fit ​​block. Arc-shaped grooves are provided on both sides of the end of the slide groove near the inside of the connecting cylinder, and the width of the arc-shaped grooves corresponds to the width of the snap-fit ​​block.

[0012] Preferably, the inner wall of the sleeve ring is tightly fitted to the outer wall of the connector, and the outer wall of the sleeve ring is correspondingly fitted to the inner wall of the receiving groove. A knob ring is fixedly connected to the outer wall of the end of the sleeve ring away from the connecting cylinder.

[0013] Preferably, a power transmission cable is fixedly connected inside the end of the connector away from the connecting cylinder, and the power transmission cable is electrically connected to the connecting piece. Copper sheets are attached to both sides of the inside of the insertion hole. A power supply cable is provided at the end of the connecting cylinder away from the connector, and the power supply cable is electrically connected to the copper sheet inside the insertion hole.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The knob ring moves the connecting ring into the receiving groove, simultaneously ensuring that the outer walls of the sealing ring and the connecting ring are tightly fitted against the inner wall of the receiving groove, thus achieving a seal. The movement of the sealing ring also pushes the surrounding airbag, causing it to move towards one end of the fixed ring. Since the side of the fixed ring is tilted towards the connector, the internal diameter of the surrounding airbag expands as it is squeezed and moved, causing it to be squeezed outward. This further ensures that the outer wall of the surrounding airbag fits against the inner wall of the receiving groove, thus sealing the inside of the receiving groove again and further preventing moisture from entering, improving the waterproof performance during connection.

[0016] 2. The rotating sleeve ring drives the rotating sealing ring, which in turn rotates the locking block to the arc-shaped groove near the inner end of the connecting cylinder. This effectively prevents the sealing ring from moving in the opposite direction, allowing the sealing ring to continuously compress the surrounding airbag. The surrounding airbag, in turn, compresses the connector through the fixing ring, preventing the connector from being pulled out and ensuring a secure connection between the connector and the connecting cylinder, preventing accidental detachment. When separation is needed, the knob ring can be easily rotated, causing the knob ring to rotate through the sleeve ring, which in turn rotates the locking block back to the position of the sliding groove. The reverse push from the surrounding airbag then pushes the sealing ring to move in the opposite direction along the sliding groove, thus separating the locking block from the receiving groove and facilitating the pull-out of the connector to release the fixation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-5The power plug shown includes a connector 1, characterized in that: a connector tube 2 is inserted into one end of the connector 1; a connecting ring 101 is sleeved around the outer wall of the end of the connector 1 away from the connecting tube 2; a sealing ring 3 is fixedly connected to the end of the connecting ring 101 near the connecting tube 2; a surrounding airbag 4 is arranged around the side of the sealing ring 3 away from the connecting ring 101; the outer wall of the connector 1, the sealing ring 3, and the surrounding airbag 4 are sleeved around each other; multiple connecting pieces 103 are fixedly connected around the end of the connector 1 near the connecting tube 2; a receiving groove 201 is formed inside the end of the connecting tube 2 near the connector 1; multiple sliding grooves 202 are formed around the inner wall of the receiving groove 201 near the connector 1; the sealing ring 3... Multiple snap-fit ​​blocks 301 are arranged around the outer wall. The snap-fit ​​blocks 301 slide and snap into the interior of the sliding groove 202. The connecting piece 103 is inserted into the corresponding insertion hole 203. The outer wall of the connecting cylinder 2 blocks external rainwater from entering. At the same time, the knob ring 102 can be moved into the interior of the receiving groove 201, thereby causing the knob ring 102 to drive the sleeve ring 101 to move into the receiving groove 201. At the same time, the outer walls of the sealing ring 3 and the sleeve ring 101 are tightly fitted with the inner wall of the receiving groove 201, thereby achieving a seal. Furthermore, the movement of the sealing ring 3 can push the surrounding airbag 4 to move, thereby causing the surrounding airbag 4 to move towards one end of the fixing ring 401 to achieve a seal, further blocking water vapor from entering and improving the waterproof performance during connection.

[0027] The connecting ring 101 drives the sealing ring 3 to rotate, which in turn drives the locking block 301 to rotate to the arc-shaped groove at one end of the slide groove 202 near the inside of the connecting cylinder 2. This effectively prevents the sealing ring 3 from moving in the opposite direction, thus enabling the sealing ring 3 to continuously compress the surrounding airbag 4. The surrounding airbag 4 then compresses the connector 1 through the fixing ring 401, preventing the connector 1 from being pulled out. This ensures the connection and fixation between the connector 1 and the connecting cylinder 2, preventing accidental disengagement. This causes the locking block 301 to rotate back to the position of the slide groove 202. Then, under the reverse push of the surrounding airbag 4, the sealing ring 3 drives the locking block 301 to move in the opposite direction along the slide groove 202, thereby disengaging the locking block 301 from the receiving groove 201, making it easy to pull out the connector 1 and release the fixation.

[0028] like Figure 2 , Figure 5As shown, one end of the receiving groove 201 has an insertion hole 203 that corresponds to the connecting piece 103. The outer diameter of the connector 1 is smaller than the inner diameter of the receiving groove 201. The outer diameter of the sealing ring 3 corresponds to the inner diameter of the receiving groove 201. A power transmission cable is fixedly connected inside the end of the connector 1 away from the connecting cylinder 2, and the power transmission cable is electrically connected to the connecting piece 103. Copper sheets are attached to both sides of the insertion hole 203. A power supply cable is provided at the end of the connecting cylinder 2 away from the connector 1, and the power supply cable is connected to the insertion hole. The copper sheets inside 203 are electrically connected to each other. The connector 1 is inserted into the receiving groove 201 of the connecting cylinder 2, so that the connecting piece 103 and the insertion hole 203 are inserted into each other. The outer wall of the connecting cylinder 2 blocks external rainwater from entering. At the same time, the knob ring 102 can be moved into the receiving groove 201, which in turn causes the knob ring 102 to drive the sleeve ring 101 to move into the receiving groove 201. At the same time, the outer walls of the sealing ring 3 and the sleeve ring 101 are tightly fitted with the inner wall of the receiving groove 201, thereby achieving a seal.

[0029] like Figure 3 , Figure 4 As shown, a fixing ring 401 is provided at one end of the surrounding airbag 4 near the connecting cylinder 2. The fixing ring 401 is fixedly connected to the outer wall of the connecting head 1. The side of the fixing ring 401 near the surrounding airbag 4 is inclined towards the center of the connecting head 1. The movement of the sealing ring 3 can push the surrounding airbag 4 to move, thereby causing the surrounding airbag 4 to move towards one end of the fixing ring 401. Since the side of the fixing ring 401 is inclined towards the side of the connecting head 1, its inner wall and the outer wall of the fixing ring 401 are engaged when the surrounding airbag 4 is squeezed and moved. As the side wall of the fixing ring 401 is inclined, it can drive the inner diameter of the surrounding airbag 4 to expand, thereby driving the surrounding airbag 4 to be squeezed outward, thereby causing the outer wall of the surrounding airbag 4 to fit against the inner wall of the receiving groove 201, thereby achieving a seal on the inside of the receiving groove 201 again and further preventing water vapor from entering.

[0030] like Figure 2 , Figure 5As shown, one end of the slide groove 202 penetrates the inner wall edge of the receiving groove 201, and the internal dimensions of the slide groove 202 correspond to the snap-fit ​​block 301. Arc-shaped grooves are formed on both sides of the end of the slide groove 202 closest to the inside of the connecting cylinder 2, and the width of the arc-shaped grooves corresponds to the width of the snap-fit ​​block 301. The inner wall of the sleeve ring 101 is tightly fitted to the outer wall of the connector 1, and the outer wall of the sleeve ring 101 corresponds to and fits the inner wall of the receiving groove 201. A knob ring 10 is fixedly connected to the outer wall of the end of the sleeve ring 101 away from the connecting cylinder 2. 2. Rotating the knob ring 102 causes the sleeve ring 101 to rotate, which in turn causes the sleeve ring 101 to rotate the sealing ring 3, causing the snap block 301 to rotate to the arc-shaped groove at one end of the slide groove 202 near the inside of the connecting cylinder 2. This effectively prevents the sealing ring 3 from moving in the opposite direction, thereby enabling the sealing ring 3 to continuously compress the surrounding airbag 4. The surrounding airbag 4 then compresses the connector 1 through the fixing ring 401, thus preventing the connector 1 from being pulled out and ensuring the connection and fixation between the connector 1 and the connecting cylinder 2, preventing accidental detachment.

[0031] In use, one end of the connecting cylinder 2 can be easily connected to the power output terminal of the power supply equipment via a cable, and the cable of the connector 1 can be electrically connected to the corresponding input terminal of the electrical equipment. During use, the connector 1 can be easily inserted into the receiving groove 201 of the connecting cylinder 2, so that the connecting piece 103 and the insertion hole 203 are correspondingly inserted. The outer wall of the connecting cylinder 2 prevents external rainwater from entering. Simultaneously, the knob ring 102 can be moved further into the receiving groove 201, causing the knob ring 102 to move the sleeve ring 101 into the receiving groove 201. This ensures that the outer walls of the sealing ring 3 and the sleeve ring 101 are in contact with the receiving groove 201. The inner walls fit tightly together to achieve a seal, and the movement of the sealing ring 3 can push the surrounding airbag 4 to move, thereby causing the surrounding airbag 4 to move towards one end of the fixing ring 401. Since the side of the fixing ring 401 is inclined towards the side of the connector 1, when the surrounding airbag 4 is squeezed and moved, its inner wall and the outer wall of the fixing ring 401 are interlocked. As the side wall of the fixing ring 401 is inclined, it can drive the inner diameter of the surrounding airbag 4 to expand, thereby driving the surrounding airbag 4 to be squeezed outward, and thus causing the outer wall of the surrounding airbag 4 to fit together with the inner wall of the receiving groove 201, thereby achieving a seal on the inside of the receiving groove 201 again, further preventing water vapor from entering and improving the waterproof performance during connection.

[0032] Simultaneously, during use, the locking block 301 and the slide groove 202 can slide and connect with each other. When the knob ring 102 drives the sleeve ring 101 to press inward, the sealing ring 3 is pushed into the receiving groove 201. The sealing ring 3 then drives the locking block 301 to move along the slide groove 202. Furthermore, when fixing is required, the knob ring 102 can be easily rotated to rotate the sleeve ring 101, which in turn drives the sealing ring 3 to rotate. This causes the locking block 301 to rotate to the arc-shaped groove near the inner end of the connecting cylinder 2 in the slide groove 202, effectively preventing the sealing ring 3 from moving in the opposite direction. This ensures that the sealing ring 3 continuously surrounds the airbag 4. The airbag 4 is compressed, and the connecting head 1 is compressed by the fixing ring 401, thus preventing the connecting head 1 from being pulled out. This ensures the connection and fixation between the connecting head 1 and the connecting cylinder 2, preventing accidental detachment. At the same time, when separation is required, the knob ring 102 can be rotated easily. The knob ring 102 drives the sealing ring 3 to rotate through the sleeve ring 101, which causes the locking block 301 to rotate back to the position of the slide groove 202. Then, under the reverse push of the airbag 4, the sealing ring 3 can drive the locking block 301 to move in the opposite direction along the slide groove 202, thereby realizing the separation of the locking block 301 from the receiving groove 201, making it easy to pull out the connecting head 1 and release the fixation.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
