[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments.

[0024] Embodiment 1:

[0025] As shown in Attach Figure 1 to Attach Figure 5 shown:

[0026] The utility model provides an adjustable cylindrical formwork, comprising: an outer cylinder body 1; the outer cylinder body 1 adopts a semi-circular ring plate structure, and through screw hole structures are arranged in an annular array on both the upper and lower sides of the outer cylinder body 1. Semi-circular ring groove structures are arranged on both the upper and lower sides of the inner wall of the outer cylinder body 1, and through screw hole structures are arranged in an annular array in the semi-circular ring grooves on both the upper and lower sides of the inner wall of the outer cylinder body 1; a group of side plates 101 with a rectangular plate structure are fixedly arranged on both sides of the outer cylinder body 1, and a group of through screw hole structures are arranged on both the upper and lower sides of one side of the side plates 101; a limiting plate 105 with a rectangular block structure is fixedly connected to the outer sides of the two groups of side plates 101. A rectangular groove structure is arranged at the bottom of the limiting plate 105, and the width of the rectangular groove at the bottom of the limiting plate 105 matches the width of the two groups of side plates 101. A group of rectangular groove structures are arranged on both sides of the inner wall of the limiting plate 105. Through screw hole structures are arranged on both the upper and lower sides of the limiting plate 105, and a through rectangular through groove structure is arranged at the rear side of the top of the limiting plate 105.

[0027] Wherein, a limiting strip 102 with a rectangular rod structure is fixedly arranged on one side of the side plate 101.

[0028] Wherein, a fixing rod 106 with a U-shaped rod structure is fixedly arranged on the top of the limiting plate 105, and a spring is sleeved on the outer side of the fixing rod 106.

[0029] Wherein, a sliding block 107 with a wedge-shaped block structure is slidably arranged on the outer side of the fixing rod 106; a group of baffles 108 with an F-shaped plate structure are fixedly arranged at the bottoms of both sides of the sliding block 107, and the baffles 108 are arranged corresponding to the positions of the two groups of screw holes of the limiting plate 105; a group of bolts 109 are arranged in the screw holes on both the upper and lower sides of the limiting plate 105 through threaded cooperation.

[0030] The specific usage method and function of this embodiment:

[0031] During use, it is necessary to combine and connect two groups of outer cylinders 1. First, splice the two groups of outer cylinders 1 so that the side plates 101 on both sides of the two groups of outer cylinders 1 are aligned. Then, respectively sleeved two groups of limit plates 105 on the outside of each group of side plates 101, align the rectangular grooves on both sides of the inner wall of the limit plate 105 with the two groups of limit strips 102 respectively, and insert the limit plate 105 downward from the upper direction of the two groups of side plates 101, so as to snap the two groups of side plates 101 into the rectangular grooves at the bottom of the limit plate 105. When the limit plate 105 is snapped in place, the bottom end faces of the two groups of side plates 101 can contact the top of the inner wall of the limit plate 105. During this process, it can contact the inclined surface structure of the slider 107, so as to push the slider 107 to slide outward along the fixed rod 106. During this process, synchronously drive the two side baffles 108 to move outward, and make the baffle 108 lose the blockage of the screw hole. At this time, the bolt 109 can be passed through the screw holes of the limit plate 105 and the side plate 101 to fixedly connect the limit plate 105 and the side plate 101. If the limit plate 105 is not installed in place, the baffle 108 will not move away from the screw hole, so that the bolt 109 cannot be installed, thus avoiding the situation that the staff constructs under the condition that the limit plate 105 is not installed in place, resulting in accidents during the construction process. At the same time, by setting the limit plate 105, compared with the traditional method of simply combining and connecting two groups of outer cylinders 1 with screws, it can better ensure the tightness of the combination and connection of the two groups of outer cylinders 1, avoid the construction quality problems caused by the appearance of gaps between the two groups of side plates 101 during the construction process, and ensure the construction quality.

Semi-circular ring-shaped grooves are provided on the upper and lower sides of the inner wall of the inner cylinder 103. A group of semi-circular ring-shaped protrusions are fixedly arranged on the upper and lower outer walls of the inner cylinder 103. Through screw holes are arranged in an annular array on the semi-circular ring-shaped protrusions on the upper and lower sides of the inner cylinder 103; Semi-circular ring-shaped connecting rings 104 are fixedly arranged on the upper and lower sides of the inner cylinder 103, and through screw holes are arranged in an annular array on the top of the connecting ring 104.

[0035] The specific usage method and function of this embodiment:

[0036] In the present utility model, when it is necessary to change the diameter of the cylindrical construction, the inner cylinder body 103 can be installed inside the outer cylinder body 1, so that the connecting ring 104 is snapped into the semi-circular annular groove inside the outer cylinder body 1, and then the outer cylinder body 1 and the inner cylinder body 103 can be fixedly connected through the screw rod, so that the inner cylinder body 103 and the outer cylinder body 1 can be fixedly connected, thereby enabling the adjustment of the diameter inside the outer cylinder body 1 to meet the production requirements of cylinders with different diameters and improving the applicability of the device.
