[0002] The reserved hole casing is a hole reserved for the pipe to pass through brick walls, concrete beams, concrete walls and other components. Generally, the diameter of the embedded casing is two specifications larger than the diameter of the pipe to pass through the component.
[0003] At present, when workers are constructing water supply and drainage pipelines in buildings, they often need to place a section of reserved hole casing in the installation position of the water supply and drainage pipes. During actual use, the reserved hole casing for water supply and drainage in the prior art needs to be poured around the reserved hole casing with concrete, and then the reserved hole casing is disassembled after the concrete is dry. At this time, since the concrete and the reserved hole casing are closely fitted, it is difficult to remove the reserved hole casing. Forcible removal will cause the reserved hole casing to be damaged and cannot be used any more, thereby increasing the cost of construction and causing inconvenience to the workers. Therefore, it is necessary to improve it.

[0020] The technical features of this solution can be clearly explained. The solution is described below through a specific implementation method.
[0021] See also Figures 1 to 4 As shown, the present embodiment is a water supply and drainage reserved hole casing, comprising a reserved hole casing body 1, a fixing rod 2 is fixedly installed on the inner side of the reserved hole casing body 1, a movable plate 3 and a first spring 4 are movably sleeved on the outer surface of the fixing rod 2, a round rod 5 is fixedly installed on the outer side of the first spring 4, a sealing plate 6 is fixedly connected to the tail end of the round rod 5, and two arc blocks 7 are movably sleeved on the outer side of the reserved hole casing body 1.
[0022] Through the cooperation between the movable plate 3 and the fixed rod 2, the movable plate 3 can drive the sealing plate 6 to move left and right along the outer surface of the fixed rod 2 and separate from the arc block 7, so that the arc block 7 can be disassembled through the cooperation between the reserved hole sleeve body 1 and the arc block 7. At this time, the limit of the arc block 7 will be released, so that a gap will be generated between the arc block 7 and the dry concrete, which is convenient for disassembly.
[0023] Among them, a mounting plate 13 is fixedly installed at the bottom of the reserved hole sleeve body 1, two mounting rods 8 are movably sleeved inside the mounting plate 13, and a connecting plate 9 is fixedly connected to the top of the two mounting rods 8. The outer surfaces of the mounting rods 8 are movably sleeved with a second spring 10, and a fixing plate 11 is fixedly installed on the inner side of the reserved hole sleeve body 1, and a threaded rod 12 is threadedly connected to the top of the fixing plate 11.
[0024] Through the cooperation between the threaded rod 12 and the fixing plate 11 , the threaded rod 12 can be rotated along the inside of the fixing plate 11 and moved up and down, so that the connecting plate 9 can be squeezed through the cooperation between the threaded rod 12 and the connecting plate 9 .
[0025] The sealing plate 6 and the arc block 7 are movably connected, and a circular ring is formed between the two arc blocks 7 and the sealing plate 6 .
[0026] Through the cooperation between the sealing plate 6 and the arc block 7, the outside of the reserved hole casing body 1 can be sealed to prevent concrete from penetrating into the outside of the reserved hole casing body 1 and making it difficult to disassemble.
[0027] There are two first springs 4 , and both first springs 4 are elastically supported between the two movable plates 3 .
[0028] Through the design of the first spring 4, the movable plate 3 has good elastic reset performance. At this time, the first spring 4 is in a compressed state, so it will apply an elastic force to the movable plate 3, so that the movable plate 3 can drive the round rod 5 to squeeze the sealing plate 6, so that the sealing plate 6 and the arc block 7 can be more closely matched.
[0029] The mounting rod 8 is in a conical shape, and the bottom end of the mounting rod 8 passes through the ground.
[0030] By passing the installation rod 8 through the ground, the reserved hole sleeve body 1 is prevented from positional displacement. At this time, concrete can be poured on the edge of the arc block 7, thereby reserving an installation position for the drainage pipe.
[0031] The second spring 10 is elastically supported between the connecting plate 9 and the mounting plate 13 , and the bottom end of the threaded rod 12 is extruded and connected to the connecting plate 9 .
[0032] The design of the second spring 10 enables the connecting plate 9 to have good elastic reset performance, thereby driving the mounting plate 13 to separate from the ground.
[0033] The working principle and use process of this utility model:
[0034] First, through the cooperation between the fixing plate 11 and the threaded rod 12, the threaded rod 12 can be rotated along the top of the fixing plate 11 and moved up and down, so that the connecting plate 9 can be squeezed by the cooperation between the threaded rod 12 and the connecting plate 9. At the same time, due to the cooperation between the mounting rod 8 and the mounting plate 13, the mounting rod 8 can be driven to pass through the mounting plate 13 to fix it, and it can be installed without carrying screws;
[0035] Afterwards, through the cooperation between the movable plate 3 and the fixed rod 2, the movable plate 3 can drive the sealing plate 6 to move left and right along the outer surface of the fixed rod 2 and separate from the arc block 7, so that the arc block 7 can be disassembled through the cooperation between the reserved hole sleeve body 1 and the arc block 7. At this time, the limit of the arc block 7 will be released, so that a gap will appear between the arc block 7 and the concrete, and then the arc block 7 can be driven to move, which is convenient for its disassembly.
