Description

Antistatic protective pail with easy tilt adjustment

The present invention relates to an antistatic protection container that is easy to adjust the inclination, and comprises a main body of the upper convex hemispherical and open top and bottom structure, and constitutes a length adjusting opening of the pipe structure assembled to the open bottom of the main body, The upper part is assembled with a lid, and the lower side is composed of a hemispherical inclined knob which is convex upward. The length adjusting device is installed so as to surround the still water, and the main body is provided on the length adjusting device. Assemble the sphere and the lid in sequence, and configure the anti-static protection container for fixing the inclined adjustment mechanism to the main body by the fixing means, to protect the anti-static, and to adjust the position of the inclined adjustment mechanism with respect to the main body It is easy to match.

In general, an anti-exhaust guard is a wrap around and protects the exponential warfare that controls the water flow and the singularity between the pipelines. It consists of a lid that closes the top, and the anti-static protective container prevents foreign matter from entering the anti-static and anti-static handles.

Conventional anti-static protection box is simply composed of a long pipe structure connecting the ground while surrounding the exponential warfare, or built a base on the ground around the exponential warfare with brick, and composed of a manhole-like structure on the foundation.

However, as the conventional anti-exposure protection container is not easy to install and easy to manage after construction, technologies for improving this are being developed. For example, in Korean Patent Registration No. 750345, the basic block and the basic block are provided. A plunging support having a masonry pipe masonry installed on the red brick and a PE structured wall tube seated on an upper portion of the masonry pipe, a fixed portion fixed to an upper end of the PE structured wall tube, and a support portion extending from the fixed portion; The content of the 'waterworks dividing manhole', which is supported by the reinforcement support and includes a reinforcement support plate having an inner diameter larger than the outer diameter of the PE structure wall tube and the reinforcement fixed to the reinforcement support plate, is posted.

And the example of the technology for adjusting the inclination and height of the manhole, in Korea Patent Registration No. 1535946, the manhole frame communicating with the interior of the valve chamber body on the upper side of the valve chamber body is inclined by several screw height adjusters In the valve chamber installed to be adjustable in height, the lower portion of the manhole frame is formed with a tubular vertical connecting pipe for installing the upper portion of the rubber tube downward, the lower portion of the rubber tube on the upper plate of the valve chamber body formed with an opening The tubular vertical connecting pipe for the installation is formed upward, the upper and lower side vertical connecting pipe portion is provided with a rubber tube, the upper and lower parts of the rubber tube is formed with a long length in the vertical direction of the upper and lower vertical connecting pipe part And corresponding to each other through the fixing bolt through the long hole and then installed by tightening as a nut, the screw height adjuster It is installed between the top of the manhole frame and the top plate of the outer tube is stretchable up and down, and between the manhole frame and the top plate of the outside of the screw height adjuster is provided with a structure that is installed up and down the length of the earth block The contents of the 'valve chamber easy to adjust the inclination and height of the manhole frame' is characterized.

However, the second illustrated 'Korean Patent Registration No. 1535946,' the valve chamber that is easy to adjust the inclination and height of the manhole frame 'is not a simple structure for adjusting the inclination and height, by turning the screw height adjuster to adjust the inclination The length of the left and right height adjusters have to be adjusted to different lengths, but there is an inconvenience that can not be applied directly to the desired slope, and there is a problem that there is a limitation of the slope adjustment that can be formed within the difference in the diameter of the movable earth block and fixed earth block there was.

In addition, in the case of the 'waterworks dividing manhole' of the first patent registration No. 750345 and the conventional general anti-static protective casing or mandrel-shaped exponential protective casing, the upper portion of the exponential protective casing close to the ground to fit the site of the site It was not easy to adjust the inclination, and there was a problem that it was not easy to adjust the height of the antistatic guard box according to the construction site. There is a problem that the cracks and breakage of the pipelines act on the surrounding pipelines, resulting in leakage of the pipelines.

Therefore, the present invention is to solve the above problems, the upper convex up the hemispherical and the upper and lower structure of the main body of the structure, the pipe structure of the assembly structure is assembled into the lower part of the main body, the top and bottom open The lid is assembled and the lower inner surface is composed of a hemispherical inclined knob which is convex upward. The length adjusting device is installed so as to surround the still water, the main body is provided on the length adjusting device, and the inclined adjusting device and the lid are sequentially placed on the upper part of the main body. To assemble and secure the inclined guard to secure the inclined adjustment mechanism to the main body by means of fastening means, to protect the exponential warfare, and to easily match the inclination of the lid with the inclination of the ground by adjusting the position of the inclined adjuster relative to the main body. do.

In addition, the assembling hole formed in the center is formed and constitutes a plate-shaped body support plate, the packing is assembled in the assembly hole, the body support plate is integrally coupled to the lower part of the body, the height adjustment opening is assembled to fit into the packing, According to the position adjustment of the main body assembled in the height adjustment port to adjust the height of the whole protective container.

As described above, the present invention constitutes a main body of a hemispherical and open top and bottom structure convex upward, and constitutes a length adjusting mechanism of a pipe structure that is assembled into the open lower part of the main body, and the upper and lower open upper part is assembled with a lid and a lower part. The inner side is composed of a convex hemispherical inclined upwards, the length adjusting device is installed so as to surround the index water, the main body is installed on the length adjusting part, and the inclined adjusting part and the lid are assembled in order, and fixed. By means of the means to configure the anti-static protection container for fixing the inclined adjustment mechanism to the main body, it is effective to protect the antistatic and to easily match the inclination of the lid and the inclination of the ground by adjusting the position of the inclined adjustment mechanism relative to the main body.

In addition, the assembling hole formed in the center is formed and constitutes a plate-shaped body support plate, the packing is assembled in the assembly hole, the body support plate is integrally coupled to the lower part of the body, the height adjustment opening is assembled to fit into the packing, According to the position adjustment of the main body is assembled in the height adjustment has the effect of easy adjustment of the height of the whole water-proof protective pail.
