Further, described lock part comprises lock and lock, and described upper lock is fixedly connected with the other end of described strut bar, and described upper lock offers lockhole.
Further, the first-class spacing of described upper lock offer multiple lockhole.
Further, described strut bar comprises quiet bar and lever, and described lever can be stretched relative to described quiet bar, one end of described hook-type engagement section and the end of described quiet bar hinged, described upper lock is fixedly connected with the end of described lever; Or one end of described hook-type engagement section and the end of described lever hinged, described upper lock is fixedly connected with the end of described quiet bar.
Further, described warning sign is fixedly connected with department of assembly, and described department of assembly offers the installation opening that can insert described strut bar, and described department of assembly is connected with governing screw at installation opening place.
Further, one end of described hook-type engagement section is fixedly connected with catch, and described catch is positioned at the both sides of one end of hook-type engagement section and the hinged place, one end of strut bar.
Compared with prior art, manhole obturator of the present invention has following characteristics and advantage:
1, manhole obturator of the present invention, compact conformation, is convenient to deposit, carry, easy to use.
2, manhole obturator of the present invention, can realize the object warning staff and closed manhole.
After reading the specific embodiment of the present invention by reference to the accompanying drawings, the features and advantages of the invention will become clearly.

Detailed description of the invention
As shown in Figures 1 to 3, the present embodiment provides a kind of manhole obturator, comprises warning sign 41, strut bar, hook-type engagement section 2 and lock part.Strut bar comprises quiet bar 11 and lever 12, lever 12 can be stretched relative to quiet bar 11, overall length after lever 12 and quiet bar 11 extend just in time can across man-hole opening, when manhole obturator does not use, lever 12 is shunk in quiet bar 11, reduce the overall volume of manhole obturator, be easy to carry, deposit.Warning sign 41 is fixedly connected with department of assembly 42, and department of assembly 42 offers the installation opening that can insert strut bar, and described department of assembly 42 is connected with governing screw 43 at installation opening place.In the present embodiment, the quiet bar 11 of strut bar inserts in the installation opening of warning sign 41, when regulating warning sign 41 to be positioned at manhole middle position, screws governing screw 43 with the position of fixing warning sign 41.One end of hook-type engagement section 2 and quiet bar 11 end of strut bar hinged, and one end of hook-type engagement section is fixedly connected with catch 21 in the both sides of hinged place, to avoid hook-type engagement section 2 artificially to be disassembled from strut bar like a cork, the upper lock 3 in lock part is fixedly connected with lever 12 end of strut bar; Lever 12 end of one end of hook-type engagement section 2 and strut bar can certainly be made hinged, and the upper lock 3 in lock part is fixedly connected with quiet bar 11 end of strut bar.The other end of hook-type engagement section 2 can be sticked in the bolt hole 51 of manhole flange 5, and upper lock 3 can insert in the bolt hole 51 of manhole flange 5.Equally spacedly on upper lock 3 offer multiple lockhole 31, lockhole 31 hangs up lock, just on the basis of hook-type engagement section engaging bolt hole 51, manhole obturator can be locked on manhole flange 5.Equally spaced multiple lockhole 31 can guarantee that manhole obturator is suitable for the manhole flange 5 of the different multi-series of thickness.As shown in Figure 2, the plane at the end place of the other end of hook-type engagement section 2 lower than described strut bar place plane but and distance between described strut bar lower surface be less than the thickness of manhole flange, i.e. d1<d2; Or as shown in Figure 3, the plane at the end place of the other end of hook-type engagement section 2 is higher than described strut bar lower surface.Certain hook-type engagement section 2 can also have various deformation to be sticked on bolt hole 51 to make hook-type engagement section 2, does not repeat them here.Like this by engaging, the locking of hook-type engagement section 2 and lock part and manhole flange 5, guarantee manhole obturator in use, hook-type engagement section 2 artificially can not be disassembled from bolt hole 51 under the condition not opening lock part like a cork by other staff.
A kind of manhole obturator of the present embodiment, in use, first hook-type engagement section 2 is sticked in the bolt hole 51 of manhole flange 5, then rotary support bar by the relative displacement elongate support bar of quiet bar 11 and lever 12, upper lock 3 is sticked in the bolt hole 51 of manhole flange 5 opposite side, warning sign 41 is regulated to make warning sign 41 be positioned at manhole middle position and screw governing screw 43 in the process, by lock hanging on lockhole 31, just manhole obturator can be locked on manhole flange 5, to realize the object warning staff and closed manhole.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
