[0027] In the description of the present utility model, unless otherwise clearly defined, words such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0028] It can be understood that, referring to Figures 1 to 5 , an inflation valve of the present utility model includes a valve seat 100 and a cover body 200. The valve seat 100 is provided with an installation groove 110, an air hole 120 is provided on the bottom wall of the installation groove 110, a valve plate 300 is slidably connected to the valve seat 100, and the valve plate 300 is used to block the air hole 120. A first sleeve 130 protrudes from the bottom wall of the installation groove 110, the first sleeve 130 surrounds the air hole 120, a limiting ring 131 protrudes from the outer peripheral wall of the first sleeve 130, and a plug-in groove 140 is formed between the outer wall of the first sleeve 130 and the wall surface of the installation groove 110; the cover body 200 is connected to the valve seat 100, a second sleeve 210 and a plug-in portion 220 protrude from one side of the cover body 200, the second sleeve 210 surrounds the plug-in portion 220, a snap ring 211 protrudes from the inner peripheral wall of the second sleeve 210, the second sleeve 210 can be inserted into the plug-in groove 140, the plug-in portion 220 can be inserted into the inner cavity of the first sleeve 130, the plug-in portion 220 and the first sleeve 130 are in interference fit, and the snap ring 211 can be buckled on the limiting ring 131 to limit the second sleeve 210 from disengaging from the first sleeve 130.

[0029] Install the valve seat 100 on the air vent of the inflatable product, and the gas enters and exits the air vent along the air hole 120, and the gas inlet and outlet are restricted by the valve plate 300 blocking the air hole 120. During sealing, by covering the cover body 200 on the valve seat 100, the second sleeve 210 is inserted into the plug-in groove 140, and at the same time the plug-in portion 220 is inserted into the inner cavity of the first sleeve 130. Since the first sleeve 130 surrounds the air hole 120, the inner cavity of the first sleeve 130 is sealed through the interference fit between the plug-in portion 220 and the first sleeve 130, and by the second sleeve 210 abutting against the wall surface of the plug-in groove 140, the risk of air leakage can be reduced and the sealing performance can be improved. In addition, by the snap ring 211 being buckled on the limiting ring 131 to limit the second sleeve 210 from disengaging from the first sleeve 130, the risk of the cover body 200 disengaging from the valve seat 100 can be reduced, thereby improving the stability of the seal.

[0030] It should be noted that when the valve plate 300 slides to the position where it abuts against the bottom wall of the valve seat 100, the air hole 120 can be blocked, thereby reducing the risk of gas leakage from the air hole 120. When the valve plate 300 slides to the position where it disengages from the bottom wall of the valve seat 100, gas can enter and exit the air hole 120.

[0031] Both the second sleeve 210 and the insertion part 220 are elastic and can produce elastic deformation. When the second sleeve 210 is inserted into the insertion slot 140, the second sleeve 210 can produce elastic deformation to increase the inner diameter, so that the snap ring 211 can slide along the wall surface of the limiting ring 131 to the lower side of the limiting ring 131. Through the elastic recovery of the second sleeve 210, the inner diameter decreases, so that the snap ring 211 is buckled on the limiting ring 131.

[0032] The valve seat 100 and the cover body 200 can be integrally formed through the hinge part 160, which can improve the connection strength between the valve seat 100 and the cover body 200 and reduce the possibility of the cover body 200 being lost after opening the cover.

[0033] It can be understood that with reference to Figure 3 and Figure 4 , the outer contours of the cross-sections of the limiting ring 131 and the snap ring 211 are both arc lines. Since the outer contours of the cross-sections of the limiting ring 131 and the snap ring 211 are both arc lines, when the snap ring 211 slides along the wall surface of the limiting ring 131 to the lower side of the limiting ring 131, the relative sliding of the snap ring 211 and the limiting ring 131 is guided by the mutual abutment of the two arc surfaces, which can reduce the wear between the snap ring 211 and the limiting ring 131 to improve the stability of the snap connection and limitation.

[0034] It can be understood that with reference to Figure 3 , a first guiding part 132 is provided at one end of the first sleeve 130 away from the air hole 120. Along the axial direction of the first sleeve 130, the inner diameter of the first guiding part 132 gradually decreases in the direction approaching the air hole 120. Since the inner diameter of the first guiding part 132 gradually decreases in the direction approaching the air hole 120 along the axial direction of the first sleeve 130, by sliding the insertion part 220 along the inner side wall of the first guiding part 132, the insertion part 220 can be guided to gradually align with and insert into the inner cavity of the first sleeve 130, thereby improving the accuracy and stability of the insertion and sealing of the insertion part 220.

[0035] It can be understood that with reference to Figure 4, at one end of the insertion part 220 away from the cover body 200, a second guiding part 221 is provided, and along the axial direction of the insertion part 220, the outer diameter of the second guiding part 221 gradually increases in the direction approaching the cover body 200. Since along the axial direction of the insertion part 220, the outer diameter of the second guiding part 221 gradually increases in the direction approaching the cover body 200, by sliding the first sleeve 130 along the outer side wall of the second guiding part 221, the first sleeve 130 can be guided to gradually align with and be sleeved on the insertion part 220, thereby improving the accuracy and stability of the insertion and sealing of the insertion part 220.

[0036] It can be understood that referring to Figure 1 and Figure 4 , an opening groove 222 is formed on the end face of the insertion part 220 facing away from the cover body 200, a cross-shaped reinforcing rib 223 is provided on the bottom wall of the opening groove 222, and the cross-shaped reinforcing rib 223 is connected to the side wall of the opening groove 222. When the insertion part 220 is inserted into the inner cavity of the first sleeve 130, the opening groove 222 can communicate with the inner cavity of the first sleeve 130, so that the gas leaking from the air hole 120 can enter the opening groove 222, so that the side wall of the opening groove 222 is pressed against the inner wall of the first sleeve 130 by the gas pressure, and the sealing stability can be improved. In addition, by connecting the side wall of the opening groove 222 with the cross-shaped reinforcing rib 223, the structural strength of the insertion part 220 can be improved to reduce the risk of the insertion part 220 being deformed under pressure, thereby improving the sealing stability.

[0037] It can be understood that referring to Figure 3 and Figure 4 , the outer diameter of the first sleeve 130 gradually increases in the axial direction towards the air hole 120, and the inner diameter of the second sleeve 210 gradually increases in the axial direction away from the cover body 200. Since the outer diameter of the first sleeve 130 gradually increases in the axial direction towards the air hole 120, and the inner diameter of the second sleeve 210 gradually increases in the axial direction away from the cover body 200, when the first sleeve 130 is inserted into the insertion groove 140, the inner wall of the second sleeve 210 can abut against the outer wall of the first sleeve 130, gradually guiding the second sleeve 210 to align with and insert into the insertion groove 140, and the accuracy and stability of the insertion of the second sleeve 210 can be improved.

[0038] It can be understood that referring to Figure 3 and Figure 5The valve plate 300 is provided with a push rod 310, and a vertical sliding hole 150 is provided at the center of the bottom wall of the mounting groove 110, and the push rod 310 is slidably connected to the sliding hole 150. The push rod 310 is slidably connected to the sliding hole 150, so that the push rod 310 can be guided to slide in the vertical direction toward or away from the valve seat 100, and the valve plate 300 can be driven to slide, so that the stability of the movement of the valve plate 300 can be improved, thereby improving the stability of blocking the air hole 120, and the push rod 310 is convenient for the user to apply force to push the valve plate 300 away from the air hole 120 to release the gas, thereby improving the convenience of deflation.

[0039] Specifically, refer to Figure 3 and Figure 5 The push rod 310 is provided with a conical limiting portion 311. Along the axial direction of the push rod 310, the diameter of the conical limiting portion 311 gradually increases in the direction approaching the valve plate 300. The conical limiting portion 311 can abut against the bottom wall of the mounting groove 110 to limit the push rod 310 from sliding in the direction of the notch away from the mounting groove 110. When the push rod 310 is inserted into the sliding hole 150 from the bottom of the valve seat 100 upward, the diameter of the sliding hole 150 is gradually enlarged by the conical limiting portion 311, and the conical surface of the conical limiting portion 311 guides the conical limiting portion 311 to pass through the sliding hole 150, so that the valve plate 300 is assembled to the valve seat 100, which can improve the convenience of assembling the valve plate 300. In addition, the conical limiting portion 311 abuts against the bottom wall of the mounting groove 110 to limit the push rod 310 from sliding in the direction of the notch away from the mounting groove 110, which can reduce the risk of the valve plate 300 detaching from the valve seat 100, thereby improving the stability of the assembly of the valve plate 300.

[0040] It is understandable that, referring to Figure 2 and Figure 4 A pressing groove 230 is provided on the side of the cover body 200 away from the plug-in portion 220, and a plurality of first anti-slip strips 231 are protruding from the wall surface of the pressing groove 230, and the plurality of first anti-slip strips 231 are evenly spaced. By providing the pressing groove 230 on the side of the cover body 200 away from the plug-in portion 220, it is convenient for the user to apply force to press the cover body 200, so as to improve the convenience of covering, and by protruding from the wall surface of the pressing groove 230, a plurality of first anti-slip strips 231 are evenly spaced, so as to increase the friction between the user's hand and the pressing groove 230, thereby reducing the risk of the user's hand slipping in the pressing groove 230, so as to improve the stability of covering.

[0041] It is understandable that, referring to Figure 1 , Figure 2 and Figure 4, the cover body 200 is provided with an opening part 240, and a plurality of second anti-slip strips 241 are convexly arranged on both opposite sides of the opening part 240, and the plurality of second anti-slip strips 241 are arranged at uniform intervals.
