[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] This specific embodiment provides a pressure tank and a pressure tank cover, which solves the technical problem in the prior art where the pressure tank cover is time-consuming and labor-intensive to install on the tank body by means of a locking buckle.

[0026] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0027] Reference Figures 1-4 This utility model provides a pressure tank cover, including a cover body 1, an adjusting member 2, and an arc-shaped expansion hoop 3. The adjusting member 2 is installed on the cover body 1, specifically, there is an installation gap between the adjusting member 2 and the cover body 1, which facilitates the installation of the arc-shaped expansion hoop 3. At least two arc-shaped expansion hoops 3 are provided, evenly distributed along the circumference of the cover body 1. To facilitate the installation of the arc-shaped expansion hoop 3, the arc-shaped expansion hoop 3 includes a connected arc-shaped portion 34 and a connecting plate 31. The connecting plate 31 is installed on the inner side (arc center side) of the arc-shaped portion 34, that is, the connecting plate 31 is located in the first slide rail formed between the cover body 1 and the adjusting member 2, which facilitates the movement of the connecting plate 31. To facilitate the movement of the connecting plate 31, a connecting post 32 is provided at one end of the connecting plate 31. The adjusting member 2 is provided with... An adjustment knob 21 is provided, and an arc-shaped groove 22 is provided at one end of the adjustment knob 21 near the cover body 1. The arc-shaped groove 22 is eccentrically positioned, that is, the center of the arc of the arc-shaped groove 22 is offset from the circle of the cover body 1, and the arc-shaped groove 22 extends along the circumferential direction of the cover body. Rotating the adjustment knob 21 can simultaneously drive at least two arc-shaped expansion hoops 3 to move, so that multiple arc-shaped expansion hoops 3 can simultaneously extend outward or fit against the circumferential surface of the cover body 1. This makes it convenient for the arc-shaped expansion hoops 3 to press against and loosen the barrel body. Since the arc-shaped groove 22 is used to install connecting posts 32, the number of connecting posts 32 is the same as the number of arc-shaped grooves 22. This makes it convenient to place one connecting post 32 in one arc-shaped groove 22. People can select the number of arc-shaped expansion hoops 3 as needed, and at the same time, the position of the arc-shaped groove is set accordingly.

[0028] With this setup, by controlling the adjustment knob 21, at least two arc-shaped expansion hoops 3 can be moved to control the two arc-shaped expansion hoops 3 to simultaneously retract inward and expand outward, thereby closing or opening the opening of the barrel and achieving a one-button opening and closing effect.

[0029] To further optimize the design, a positioning plate 4 is provided at the center of the cover 1 to facilitate the limiting of the connecting plate 31. The positioning plate 4 is U-shaped, so that the positioning plate 4 is installed on the cover 1 to form an installation cavity between the positioning plate 4 and the cover 1 to accommodate the end of the connecting plate 31. The positioning plate 4 is provided with a second slide rail 41 for the connecting post 32 to slide, which facilitates the limiting of the connecting post 32 and also facilitates the insertion of the connecting post 32 into the arc groove 22.

[0030] To further optimize the design, in order to facilitate the positioning of the adjusting component 2, a recessed part corresponding to the shape and structure of the adjusting component 2 is provided on the cover 1. The adjusting component 2 is installed in the recessed part, thus limiting the adjusting component 2 to the recessed part and reducing the probability of the adjusting component 2 rotating.

[0031] To further optimize the design, and to facilitate the connection of the spraying tool to the cover 1, the cover 1 is provided with a first mounting hole and a second mounting hole. The first mounting hole is used to install the nozzle 7, and the second mounting hole is used to install the pressure relief valve 6.

[0032] To further optimize the design and enhance the strength of the adjusting component 2, a support rib 23 is provided on the adjusting component 2. The support rib 23 extends along the length of the adjusting component 2, and as shown... Figure 2 As shown, support ribs 23 are located on both sides of the adjustment knob.

[0033] To further optimize the design, and in order to limit the position of the arc-shaped expansion hoop 3 and prevent it from moving, a safety valve 5 is installed on the cover 1. A waist-shaped hole 33 is provided on the connecting plate 31. For ease of installation of the safety valve, a through hole is provided in the middle of the waist-shaped hole 33, with a diameter larger than the width of the through hole. The safety valve 5 has a third connecting part, a first connecting part 51, and a second connecting part 52 along its height. The cross-sectional area of ​​the first connecting part 51 is larger than that of the second connecting part 52, and the diameter of the first connecting part 51 is smaller than the diameter of the through hole. The first connecting part 51 is... Between the connecting plate 31 and the connecting piece 2, the first connecting part 51 is used to press the connecting plate 31 tightly. The third connecting part is used to be inserted into the adjusting piece 2. When the adjusting knob is turned, the first connecting part 51 can press against the connecting plate 31, that is, the positions on both sides of the waist-shaped hole 33, restricting the position of the connecting plate 31, that is, fixing the position of the arc-shaped expansion hoop 3. Specifically, when the pressure tank cover is installed on the tank body, the pressure inside the tank increases, which in turn drives the safety valve 5 to move downward. At the same time, the first connecting part 51 presses against the connecting plate 31, which can prevent the connecting plate 31 from moving and ensure the position of the arc-shaped expansion hoop 3.

[0034] To facilitate limiting the position of the adjusting component 2, a limiting hole is provided on the cover. The limiting post 11 passes through the limiting hole and is fixed on the cover. The limiting post is also inserted into the waist-shaped hole 33, which also facilitates limiting the distance the connecting plate 31 moves.

[0035] To further optimize the design, in order to ensure the airtightness between the lid 1 and the barrel, a sealing ring is provided on the inner wall of the lid 1. The sealing ring fits into the end of the barrel to ensure the airtightness between the two.

[0036] The scheme is further optimized by setting two arc-shaped expansion hoops and two arc-shaped grooves 22. The two arc-shaped grooves 22 form a tai chi shape, so that the adjustment knob 21 can control the two arc-shaped expansion hoops to move at the same time.

[0037] The design is further optimized by incorporating a bend in the arc-shaped portion 34 along its width to accommodate the edge of the cover 1, such as... Figure 1 As shown, the arc-shaped portion 34 includes a horizontal segment and a vertical segment, with an angle between the horizontal segment and the vertical segment to meet the peripheral requirements of the cover 1.

[0038] This application also provides a bucket, including the aforementioned pressure bucket lid, and a bucket body, with the pressure bucket lid mounted on the bucket body.
