Invention content
The purpose of the present invention is to provide a kind of manhole sealers to realize warning staff and closing manhole.
The present invention provides a kind of manhole sealer, including warning sign, supporting rod, hook-type holding section and lock part, the police Show that board is flexibly connected the supporting rod, one end and one end of the supporting rod of the hook-type holding section are hinged, the supporting rod The other end be fixedly connected with lock part.
Further, the lock part includes upper lock pillar and lock, and the other end of the upper lock pillar and the supporting rod is fixed It connects, lockhole is offered on the upper lock pillar.
Further, the first-class spacing of upper lock pillar offers multiple lockholes.
Further, the supporting rod includes quiet bar and lever, and the lever can stretch relative to the quiet bar, the hook One end of shape holding section and the end of the quiet bar are hinged, and the upper lock pillar is fixedly connected with the end of the lever;Or institute The one end and the end of the lever for stating hook-type holding section are hinged, and the upper lock pillar is fixedly connected with the end of the quiet bar.
Further, the warning sign is fixedly connected with department of assembly, and the department of assembly offers the pluggable supporting rod Installation opening, the department of assembly is connected with adjusting screw at installation opening.
Further, one end of the hook-type holding section is fixedly connected with catch, and the catch is located at hook-type holding section One end and the both sides of one end hinged place of supporting rod.
Compared with prior art, manhole sealer of the invention has the characteristics that and advantage:
1st, manhole sealer of the invention, it is compact-sized, it is easy to use convenient for storing, carrying.
2nd, manhole sealer of the invention can realize warning staff and close the purpose of manhole.
After the specific embodiment of the present invention is read in conjunction with the figure, the features and advantages of the invention will become clearer.

Specific embodiment
As shown in Figures 1 to 3, the present embodiment provides a kind of manhole sealer, including warning sign 41, supporting rod, hook-type engaging Portion 2 and lock part.Supporting rod includes quiet bar 11 and lever 12, and lever 12 can be flexible relative to quiet bar 11, lever 12 and quiet bar 11 Overall length after elongation just can across man-hole opening, when manhole sealer when not in use, lever 12 is shunk in quiet bar 11, is subtracted The small overall volume of manhole sealer, easy to carry, storage.Warning sign 41 is fixedly connected with department of assembly 42, and department of assembly 42 opens Installation opening equipped with pluggable supporting rod, the department of assembly 42 are connected with adjusting screw 43 at installation opening.The present embodiment In, the quiet bar 11 of supporting rod is inserted into the installation opening of warning sign 41, when adjusting warning sign 41 is located at manhole middle position, is screwed Adjusting screw 43 is to fix the position of warning sign 41.One end of hook-type holding section 2 and 11 end of quiet bar of supporting rod are hinged, and hook One end of shape holding section is fixedly connected with catch 21 in the both sides of hinged place, to avoid hook-type holding section 2 by artificially easily from It is disassembled on supporting rod, the upper lock pillar 3 in lock part is fixedly connected with 12 end of lever of supporting rod;It can certainly make hook One end of shape holding section 2 and 12 end of lever of supporting rod are hinged, 11 end of quiet bar of the upper lock pillar 3 in lock part and supporting rod It is fixedly connected.The other end of hook-type holding section 2 can be sticked in the bolt hole 51 of manhole flange 5, and upper lock pillar 3 can be inserted into manhole method In the bolt hole 51 of orchid 5.Multiple lockholes 31 are opened up on upper lock pillar 3 at equal intervals, lock is hung up on lockhole 31, it can be in hook-type On the basis of holding section engaging bolt hole 51 by manhole sealer lock on manhole flange 5.Equidistant multiple lockholes 31 can be with Ensure that manhole sealer is suitable for the manhole flange 5 of the different multi-series of thickness.As shown in Fig. 2, the other end of hook-type holding section 2 End where plane be less than people less than the plane where the supporting rod but with the distance between the supporting rod lower face The thickness of hole flange, i.e. d1<d2;Alternatively, as shown in figure 3, the plane where the end of the other end of hook-type holding section 2 is higher than institute State supporting rod lower face.It certain hook-type holding section 2 can also be there are many deformation so that hook-type holding section 2 is sticked in bolt hole 51 On, details are not described herein.The engaging with manhole flange 5, locking in this way by hook-type holding section 2 and lock part, it is ensured that manhole seals Close device in use, hook-type holding section 2 will not by other staff under conditions of lock part is not opened it is artificial easily from It is disassembled on bolt hole 51.
A kind of manhole sealer of the present embodiment, in use, is first sticked in manhole flange 5 by hook-type holding section 2 Bolt hole 51 in, then rotate supporting rod and by quiet bar 11 and the relative displacement elongate support bar of lever 12, upper lock pillar 3 blocks Warning sign 41 is made to be located at manhole center together in warning sign 41 in the bolt hole 51 of 5 opposite side of manhole flange, is adjusted in the process Position simultaneously screws adjusting screw 43, by lock hanging on lockhole 31, can lock manhole sealer on manhole flange 5, with reality The now purpose of warning staff and closing manhole.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck The variations, modifications, additions or substitutions that the technical staff in domain is made in the essential scope of the present invention should also belong to the present invention's Protection domain.
