Description

Technical Field

[0001] The utility model relates to an air cover structure for an air valve. Background Art

[0002] Prior art, such as the Chinese utility model patent document with publication number CN213176923U, discloses a vacuum bag air valve, comprising a base and a top cover, wherein the base is provided with a cavity wall upward, an air plug cavity and an air inlet are provided in the base, an air plug is provided in the air plug cavity and cooperates with the air inlet for opening and closing the air inlet, the cavity wall also includes a notch, the top cover is movably engaged with the base, the top cover and the notch cooperate to form an exhaust structure, and the size of the exhaust structure is controlled by relative movement between the top cover and the base, thereby performing exhaust adjustment.

[0003] Based on the above, in the prior art, the air cap and the air nozzle in the air valve are opened and closed by means of screw threads, which is a relatively common connection method. Due to cost issues, the air cap is mostly made of cheap plastic material, and the product is relatively soft after molding. Therefore, when the air cap is pinched and screwed by hand, a certain pressure will be generated on the air cap, causing local deformation of the air cap. When this deformation occurs in the position where there is a screw thread structure, it will inevitably cause the air cap and the air nozzle to be screwed together, resulting in the problem of the knob getting stuck and not being smooth during the screwing process, which needs to be improved. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems in the prior art. To this end, the utility model provides an air cover structure that is not easily deformed.

[0005] An air cap structure for an air valve designed for this purpose includes an air cap body, a rotating connection part for connecting to an air nozzle is provided on the air cap body, a holding drive part is provided on the outer side of the rotating connection part, and a transition buffer space is provided between the holding drive part and the rotating connection part.

[0006] Preferably, the rotating connection portion is a threaded connection ring, and the threaded connection ring is threadedly connected to the gas nozzle;

[0007] The gripping driving portion is an annular structure.

[0008] Preferably, the rotating connection portion and the gripping drive portion are connected with a reinforced connection portion.

[0009] Preferably, there are at least two reinforced connection parts and the transition buffer space is located between the two reinforced connection parts.

[0010] Preferably, air holes are provided on the air cover body in the rotating connection portion.

[0011] Preferably, a limiting ring that fits with the air plug is provided on the air cover body in the rotating connection part, and the air hole is provided between the limiting ring and the rotating connection part.

[0012] Preferably, anti-slip grooves are evenly distributed on the outer wall of the gripping driving part.

[0013] Compared with the prior art, the present invention is provided with a gripping drive part and a transition buffer space, so that when the air cap is rotated, the air cap can be screwed by gripping the gripping drive part. When screwing, the gripping drive part is subjected to force and deformed toward the transition buffer space. Due to the existence of the transition buffer space, the rotating connection part can be prevented from being deformed by force, thereby avoiding the problem of the air cap rotating unsmoothly due to the deformation of the rotating connection part, thereby achieving the purpose of smooth rotation of the air cap.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See also Figures 1-6 A gas cap structure for an air valve includes an air cap body 10. The air cap body 10 is provided with a rotating connection portion 110 for connecting to a gas nozzle 20. A gripping drive portion 120 is provided on the outer side of the rotating connection portion 110. A transition buffer space 100 is provided between the gripping drive portion 120 and the rotating connection portion 110. The provision of the gripping drive portion and the transition buffer space allows the gas cap to be twisted by gripping the gripping drive portion when rotating the gas cap. During twisting, the gripping drive portion is deformed toward the transition buffer space due to force. The presence of the transition buffer space prevents the rotating connection portion from being deformed by force, thereby avoiding the problem of uneven rotation of the gas cap caused by deformation of the rotating connection portion, thereby achieving the purpose of smooth rotation of the gas cap.

[0022] In the present invention, the air cap body 10, the rotating connection part 110 and the gripping driving part 120 are an integrated structure.

[0025] See also Figure 2 There are at least two reinforcing connection parts 160 and the transition buffer space 100 is located between the two reinforcing connection parts 160 .

[0026] See also Figure 2 The air cover body 10 in the rotating connection portion 110 is provided with an air hole 150 , and when the air valve is exhausting or intake, the external or internal air flow flows through the air hole 150 .

[0027] See also Figure 2 and Figure 5 A limiting ring 170 that fits with the air plug 30 is provided on the air cover body 10 in the rotating connection part 110 , and the air hole 150 is provided between the limiting ring 170 and the rotating connection part 110 .

[0028] See also Figure 1 and Figure 2 The outer wall of the gripping driving portion 120 is evenly distributed with anti-slip grooves 130 to facilitate gripping and rotation, and avoid slipping and affecting twisting.
