DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In actual use, when installing the water supply and drainage pipes, workers are required to adjust the height between the two pipes to facilitate splicing of the connections, which reduces the work efficiency of the workers.

[0021] In view of this, the utility model provides a prefabricated connection device for water supply and drainage pipes, which solves the problem that in actual use, when the water supply and drainage pipes are installed, the staff need to adjust the height between the two pipes to make the connection convenient during splicing, thereby reducing the work efficiency of the staff.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Example 1: By Figure 1-4It can be seen that a prefabricated connection device for water supply and drainage pipes includes an upper pressure plate 1, a lower support plate 11 is installed at the bottom of the upper pressure plate 1, and a rubber sleeve 16 is fixedly connected to the side where the upper pressure plate 1 and the lower support plate 11 are close to each other, wherein the rubber sleeve 16 is made of rubber material. When the two connecting pipes are leveled, the rubber sleeve 16 is put on the outer wall of the two connecting pipes to seal the gap at the connection. An adjustment device 2 is installed on both sides of the rubber sleeve 16, and the adjustment device 2 includes: two clamping plates 21, which are respectively installed on the inner walls of the upper pressure plate 1 and the lower support plate 11; two mounting plates 22 are respectively fixedly connected to the side of the two clamping plates 21 away from each other; two threaded rods 23 are provided, which are respectively The two fixing plates 22 are respectively threadedly connected to the inner walls of the two mounting plates 22, and are respectively rotatably connected to the inner walls of the upper pressing plate 1 and the lower supporting plate 11 through sealed bearings; two groups of limiting columns 24 are provided, which are respectively plugged into the inner walls of the two mounting plates 22 and fixedly connected to the inner walls of the upper pressing plate 1 and the lower supporting plate 11; two adjusting members 25 are provided, which are respectively fixedly connected to the ends of the two threaded rods 23 that are away from each other, and the ends of the adjusting members are sunk into the surface grooves of the upper pressing plate 1, and the surface is provided with an inner hexagon for easy adjustment with a wrench; wherein, through the cooperation of the adjusting members 25 and the threaded rods 23, the mounting plate 22 drives the clamping plate 21 to adjust the pipeline, and the limiting columns 24 ensure that the mounting plate 22 is stable when moving;

[0024] In the specific implementation process, it is worth noting that the upper pressing plate 1 and the lower supporting plate 11 are used to seal and fix the connection of the pipes. When the heights of the connecting pipes are different, the upper pressing plate 1 and the lower supporting plate 11 are used to wrap the pipes. After wrapping, the handle is used to drive the adjusting member 25 to rotate. When the adjusting member 25 is rotated, it will drive the threaded connection between the threaded rod 23 and the mounting plate 22, so that the mounting plate 22 moves on the outer wall of the limiting column 24, and drive the clamping plate 21 to lift the pipe. The adjusting members 25 on both sides rotate the same number of circles to lift the pipes on both sides to the same height. After the upper pressing plate 1 and the lower supporting plate 11 are fixedly connected, the clamping plate 21 can also fix the pipe, making the connection between the two pipes more stable.

[0025] Furthermore, sealing gaskets 12 are inserted at both ends of the upper pressing plate 1 and the lower supporting plate 11;

[0026] In the specific implementation process, it is worth noting that the material of the sealing gasket 12 is rubber. When the upper pressing plate 1 and the lower supporting plate 11 are merged, the sealing gasket 12 will be squeezed, and the pipe and the sealing gasket 12 are in close contact to avoid gaps and leakage.

[0027] Furthermore, a support base 15 is fixedly connected to the bottom of the lower support plate 11;

[0028] In the specific implementation process, it is worth noting that the support base 15 is used to support the upper pressing plate 1 and the lower supporting plate 11 to prevent the pipe and the fixed structure from sinking after landfilling, which would affect the connection effect.

[0029] Specifically, when using the prefabricated connection device for water supply and drainage pipes, when connecting the pipes, the two pipes are placed between the upper pressure plate 1 and the lower support plate 11, and inserted between the rubber sleeves 16. Before connecting, the heights of the two pipes are adjusted to the same height. At this time, the handle is used to drive the adjusting member 25 to rotate, and when the adjusting member 25 is rotated, the threaded rod 23 is driven to be threadedly connected with the mounting plate 22, so that the mounting plate 22 moves on the outer wall of the limit column 24, and drives the clamping plate 21 to lift the pipe, and by rotating the adjusting members 25 on both sides the same number of circles, the pipes on both sides are lifted to the same height, and after the upper pressure plate 1 and the lower support plate 11 are fixedly connected, the clamping plate 21 can also fix the pipe, making the two pipes more stable when connected, and when the upper pressure plate 1 and the lower support plate 11 are merged, the sealing gasket 12 is squeezed, and the pipe and the sealing gasket 12 are in close contact to avoid gaps and leakage. Moreover, when filling, the support seat 15 supports the pipe and the connection device.

[0030] Example 2: By Figure 1-4 The cam 33 is fixed to the upper and lower support plates 11 so as to prevent the upper and lower support plates from sliding out of the way and thus causing the cam 33 to slide in and out of the support plates 11.

[0031] In the specific implementation process, it is worth noting that when the pipe is inserted into the rubber sleeve 16, the limiting plates 31 on both sides are pressed against the outer wall of the pipe under the action of the spring 33, so that the pipe is fixed between the upper pressure plate 1 and the lower support plate 11, and cooperates with the rubber sleeve 16 to connect the two connecting pipes together;

[0032] Furthermore, the outer walls of the upper pressing plate 1 and the lower supporting plate 11 are fixedly connected with connecting blocks 13, a rubber pad 14 is pressed between the two connecting blocks 13, and the two connecting blocks 13 are fixedly connected by bolts;

[0033] In the specific implementation process, it is worth noting that the rubber pad 14 is placed between the connecting blocks 13, and the connecting blocks 13 are connected using bolts. When connecting, the rubber pad 14 is squeezed to seal the gap between the upper pressing plate 1 and the lower supporting plate 11 to avoid leakage.

[0034] Specifically, based on the above embodiment, when connecting the pipeline, the spring 33 is used to squeeze the support rod 32 so that the limit plate 31 is pressed against the outer wall of the pipeline, making it convenient when connecting. After the connection is completed, the two connecting blocks 13 are fixed with bolts, and the rubber pad 14 is squeezed to seal the upper pressure plate 1 and the lower support plate 11.
