Description

Technical Field

[0001] This utility model relates to the technical field of inflatable boat inflation valves, and in particular to a structure for an inflatable boat inflation valve. Background Technology

[0002] An inflatable rubber boat is a lightweight vessel made of rubber or other synthetic materials. It has an air valve on its hull for inflation. Inflatable rubber boats are stored empty, taking up little space and easy to store. When in use, they are inflated using the air valve.

[0003] In the prior art, the utility model patent with patent publication number CN217272012U discloses an inflation valve structure for an inflatable boat. This inflation valve structure rotates the valve cover to drive the sealing gasket to rotate, so that the first vent hole and the second vent hole are connected or misaligned, forming and closing the inflation channel. The inflation channel has a large diameter and a fast opening and closing speed, which facilitates rapid inflation.

[0004] Although the inflation valve structure in the aforementioned patent facilitates rapid inflation, in actual operation, since the valve cover is threaded, it is necessary to open and close the inflation channel by turning the valve cover, which makes it inconvenient to open and close the inflation channel, resulting in low inflation convenience. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rubber boat inflation valve structure that makes it easier to open and close the inflation channel of the air valve, thereby improving the convenience of inflating the rubber boat.

[0006] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a rubber boat inflation valve structure, comprising a valve body and an opening and closing mechanism. The valve body has an installation groove on its outer wall for connecting to the rubber boat skin. An inflation channel, matching the inflation head of an air pump, is provided through the middle of the valve body. A sealing groove is provided at the bottom end of the valve body, communicating with the inflation channel. Two sets of limiting grooves are symmetrically provided on the wall of the inflation channel. Three sets of T-shaped sliding grooves are provided at equal intervals in an annular shape at the bottom end of the valve body. The opening and closing mechanism includes a T-shaped cylindrical sealing plug, which communicates with the inflation channel... The sealing plug is tightly fitted onto the sealing groove. A connecting column is fixedly connected to the center of the top of the T-shaped cylindrical sealing plug. A limiting plate is fixedly connected to the top of the connecting column. The width of the limiting plate is the same as the width of the limiting groove. The limiting plate is slidably installed in the inflation channel by cooperating with the limiting groove. Three sets of transmission rods are rotatably connected to the bottom side of the T-shaped cylindrical sealing plug in annular shape. T-shaped sliders are slidably connected to the three sets of T-shaped grooves. The tops of the three sets of transmission rods are rotatably connected to the three sets of T-shaped sliders respectively. A sealing spring is fixedly connected between the inner side of the T-shaped slider and the inner side of the T-shaped groove.

[0007] Preferably, the bottom edge of the T-shaped cylindrical sealing plug is provided with three sets of equidistant clearance grooves. The bottom ends of the three sets of transmission rods are rotatably connected to the T-shaped cylindrical sealing plug through cooperation with the clearance grooves. The bottom ends of the three sets of T-shaped sliders are provided with connecting grooves. The top sides of the top of the three sets of clearance grooves are fixedly connected with shaft heads. The top ends of the three sets of clearance grooves are rotatably connected to the three sets of T-shaped sliders through cooperation between the shaft heads and the connecting grooves. The width of the transmission rods is the same as the width of the clearance grooves and the connecting grooves.

[0008] Preferably, the top of the valve body is fitted with a protective rubber plug through a cover that mates with the inflation channel, and a connecting rubber rod is fixedly connected between the top of the protective rubber plug and the top of the valve body.

[0009] Preferably, a sealing ring is fixedly connected to the bottom end of the sealing trough.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the valve body is fixedly connected to a suitable position on the rubber boat hull via the mounting groove. When the valve body is installed on the rubber boat, the T-shaped cylindrical sealing plug is inside the rubber boat, while the limiting plate is exposed outside. Initially, the sealing spring is in a compressed state. The compression of the sealing spring generates a thrust from the axis outwards, pushing the T-shaped slider. This causes the T-shaped slider to pull the T-shaped cylindrical sealing plug through the transmission rod, thus ensuring that the T-shaped cylindrical sealing plug tightly covers the inflation channel and the sealing groove. The T-shaped cylindrical sealing plug then functions to seal the inflation channel and the sealing groove. During inflation, the inflation head on the air pump inflation pipe is inserted into the inflation channel from the outside, pushing the limiting plate downwards. This causes the limiting plate to push the T-shaped sealing plug through the connecting column. The cylindrical sealing plug moves downward, causing the T-shaped cylindrical sealing plug to pull the T-shaped slider inward along the T-shaped groove via the transmission rod. This further compresses the sealing spring, causing the T-shaped cylindrical sealing plug to disengage from the inflation channel, opening the inflation channel. The operator holds the inflation head of the inflation tube, ensuring it is against the limiting plate, allowing the air pump to inflate the inflatable boat. After inflation, the inflation head is quickly pulled out, causing the sealing spring to rebound rapidly and push the T-shaped slider outward along the T-shaped groove. This, in turn, causes the T-shaped slider to pull the T-shaped cylindrical sealing plug upward via the transmission rod, quickly covering the inflation channel and sealing groove, closing the inflation channel. This makes opening and closing the inflation channel more convenient, improving inflation ease. Attached Figure Description

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example

[0013] Please see Figures 1-6This utility model discloses an inflatable boat inflation valve structure, comprising a valve body 1 and a T-shaped cylindrical sealing plug 7. The outer wall of the valve body 1 has an installation groove 2 for connecting to the inflatable boat skin. An inflation channel 3, which mates with the inflation head of an air pump, runs through the middle of the valve body 1. A sealing groove 4 is formed at the bottom of the valve body 1, communicating with the inflation channel 3. Two sets of limiting grooves 5 are symmetrically formed on the wall of the inflation channel 3. Three sets of T-shaped sliding grooves 6 are circumferentially spaced at the bottom of the valve body 1. The T-shaped cylindrical sealing plug 7 tightly covers the inflation channel 3 through its fit. On the sealing groove 4, a connecting post 8 is fixedly connected to the center of the top of the T-shaped cylindrical sealing plug 7. A limiting plate 9 is fixedly connected to the top of the connecting post 8. The width of the limiting plate 9 is the same as the width of the limiting groove 5. The limiting plate 9 is slidably installed in the inflation channel 3 by cooperating with the limiting groove 5. Three sets of transmission rods 10 are rotatably connected to the bottom side of the T-shaped cylindrical sealing plug 7 at equal intervals. T-shaped sliders 11 are slidably connected to the three sets of T-shaped sliding grooves 6. The tops of the three sets of transmission rods 10 are rotatably connected to the three sets of T-shaped sliders 11 respectively. A sealing spring 12 is fixedly connected between the inner side of the valve body 1 and the inner side of the T-shaped slide 6. In use, the valve body 1 is fixedly connected to the appropriate position on the rubber boat hull via the mounting groove 2, so that the valve body 1 is installed on the rubber boat. At this time, the T-shaped cylindrical sealing plug 7 is inside the rubber boat, while the limiting plate 9 is exposed outside. Initially, the sealing spring 12 is in a compressed state. The compression of the sealing spring 12 generates a thrust from the axis outward, pushing the T-shaped slider 11. This causes the T-shaped slider 11 to pull the T-shaped cylindrical sealing plug 7 through the transmission rod 10, thereby causing the T-shaped cylindrical sealing plug 7 to tightly cover the inflation channel 3 and the sealing groove 4, thus enabling the T-shaped cylindrical sealing plug 7 to seal the inflation channel 3 and the sealing groove 4. During inflation, the inflation head on the air pump inflation pipe is inserted into the inflation channel 3 from the outside, pushing the limiting plate 9 downward. This causes the limiting plate 9 to push the T-shaped cylindrical sealing plug 7 through the connecting column 8. The T-shaped cylindrical sealing plug 7 moves downward, causing the T-shaped cylindrical sealing plug 7 to pull the T-shaped slider 11 inward along the T-shaped groove 6 via the transmission rod 10. This further compresses the sealing spring 12, causing the T-shaped cylindrical sealing plug 7 to disengage from the inflation channel 3, opening the inflation channel 3. The operator holds the inflation head of the inflation tube, ensuring the inflation head is against the limiting plate 9, allowing air to be pumped into the rubber boat. After inflation, the inflation head is quickly pulled out, causing the sealing spring 12 to rebound rapidly and push the T-shaped slider 11 outward along the T-shaped groove 6. This causes the T-shaped slider 11 to pull the T-shaped cylindrical sealing plug 7 upward rapidly via the transmission rod 10, quickly covering the inflation channel 3 and the sealing groove 4, closing the inflation channel 3. This makes opening and closing the inflation channel 3 more convenient and improves inflation convenience.

[0014] The T-shaped cylindrical sealing plug 7 has three sets of equidistant, annular clearance grooves 16 on its bottom side. The bottom ends of the three sets of transmission rods 10 are rotatably connected to the T-shaped cylindrical sealing plug 7 through cooperation with the clearance grooves 16. The bottom ends of the three sets of T-shaped sliders 11 are each provided with a connecting groove 17. Shaft heads 18 are fixedly connected to both sides of the top of the three sets of clearance grooves 16. The top ends of the three sets of clearance grooves 16 are rotatably connected to the three sets of T-shaped sliders 11 through cooperation between the shaft heads 18 and the connecting grooves 17. The width of the transmission rod 10 is equal to that of the clearance grooves 16 and the connecting grooves 17. The width of 17 is the same; when the T-shaped cylindrical sealing plug 7 drives the T-shaped slider 11 to slide through the transmission rod 10, the two ends of the transmission rod 10 cooperate with the clearance groove 16 and the connecting groove 17 to limit the axial movement of the transmission rod 10, which can effectively prevent the transmission rod 10 from axially shaking, making the transmission rod 10 more stable during transmission, and thus making the T-shaped cylindrical sealing plug 7 more stable and reliable when opening and closing, so that the T-shaped cylindrical sealing plug 7 can stably return to cover the inflation channel 3 and the sealing groove 4.

[0015] The top of the valve body 1 is fitted with a protective rubber plug 13 that mates with the inflation channel 3. A connecting rubber rod 14 is fixedly connected between the top of the protective rubber plug 13 and the top of the valve body 1. By setting the protective rubber plug 13 and the connecting rubber rod 14, when not inflating, the protective rubber plug 13 is inserted into the top of the inflation channel 3 to block the inflation channel 3 and prevent dust and debris from entering the inflation channel 3. When inflating, the protective rubber plug 13 is removed from the inflation channel 3 to allow inflation, thus providing a sealing and protection function for the inside of the inflation channel 3.

[0016] A sealing ring 15 is fixedly connected to the bottom of the sealing groove 4. By setting the sealing ring 15, when the T-shaped cylindrical sealing plug 7 is covered onto the inflation channel 3 and the sealing groove 4 by the elastic force of the sealing spring 12, the T-shaped cylindrical sealing plug 7 squeezes the sealing ring 15, causing the sealing ring 15 to undergo a certain degree of compression deformation, thereby improving the sealing performance of the T-shaped cylindrical sealing plug 7 after it is installed and preventing air leakage.

[0017] This utility model discloses an inflation valve structure for an inflatable boat. In use, the valve body 1 is fixedly connected to a suitable position on the inflatable boat hull via the mounting groove 2. When the valve body 1 is installed on the inflatable boat, the T-shaped cylindrical sealing plug 7 is inside the inflatable boat, while the limiting plate 9 protrudes outside. Initially, the protective rubber plug 13 covers the outside of the inflation channel 3, and the sealing spring 12 is in a compressed state. The compression of the sealing spring 12 generates a thrust from the axis outwards, pushing the T-shaped slider 11. This causes the T-shaped slider 11 to pull the T-shaped... The cylindrical sealing plug 7, in turn, tightly covers the inflation channel 3 and the sealing groove 4. At this time, the limiting plate 9 abuts against the top of the limiting groove 5. The elastic coefficient and thickness of the sealing spring 12 meet the requirements of the operating environment, so that the sealing spring 12 provides sufficient elastic force, causing the T-shaped cylindrical sealing plug 7 to press against the sealing rubber ring 15 under the action of elastic force, thereby sealing the inflation channel 3 and the sealing groove 4. When inflating, the protective rubber plug 13 is pulled out from the inflation channel 3, and then the inflation head on the air pump inflation tube is inserted from the outside for inflation. In channel 3, the limiting plate 9 is pushed downwards, causing the limiting plate 9 to push the T-shaped cylindrical sealing plug 7 downwards via the connecting column 8. This causes the T-shaped cylindrical sealing plug 7 to pull the T-shaped slider 11 inwards along the T-shaped groove 6 via the transmission rod 10, further compressing the sealing spring 12. This disengages the T-shaped cylindrical sealing plug 7 from the inflation channel 3, opening the inflation channel 3. The operator holds the inflation head of the inflation tube, ensuring it presses against the limiting plate 9 and remains in contact with the inner wall of the inflation channel 3. The air can then be pumped into the rubber boat. After inflation, quickly pull out the inflation head. At this time, the sealing spring 12 begins to rebound quickly and pushes the T-shaped slider 11 to slide outward along the T-shaped groove 6. This causes the T-shaped slider 11 to pull the T-shaped cylindrical sealing plug 7 upward quickly through the transmission rod 10, so that the T-shaped cylindrical sealing plug 7 quickly covers the inflation channel 3 and the sealing groove 4. The T-shaped cylindrical sealing plug 7 squeezes the sealing ring 15, closing the inflation channel 3. Finally, the protective rubber plug 13 is placed on the outside of the inflation channel 3 to block the inflation channel 3.

[0018] The present invention relates to an air valve structure for inflating a rubber boat. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
