Description

Quick opening manhole

Technical field

This utility model relates to a kind of manhole sealer, more specifically, it relates to a kind of quick opening manhole.

Background technology

Manhole is sewer access hole, and a kind of often with the duct of lid, people thus hole turnover can arrange road, boiler, Xia Shui Pipe, filling shape container also include the light current well that telecommunications, cable television use, the inner passage etc. of large bridge maintenance.

At present, modal manhole structure is generally similar to disclosed in the Chinese patent that notification number is CN203450647U A kind of manhole assembly, it includes that upper cover and Xia Quan, lower circle are fixed on powder tank, and upper cover is hinged on lower circle, and described upper cover passes through Fixation kit and lower circle closing seam, be additionally provided with security component between upper cover and lower circle.This kind of upper cover in use, because of Only being fixed with two ends, under environment under high pressure, in the middle of upper cover, the area of the overwhelming majority is subject at stress, the position especially proximate to center Power is the strongest, thus makes upper cover easily produce the trend of upwards jack-up deformation, the most just loses sealing effectiveness.

For improving the problems referred to above, notification number is a kind of manhole cover disclosed in the Chinese patent of CN203517166U, its bag Include the body and lid matched each other, described body is fixed with the first hinged seat and the second hinged seat, with the stud of nut Lower end is hinged with the first hinged seat, and described lid is provided with screens auricle, screens auricle and the first hinged seat and the second hinged seat Coaxially, screens auricle is provided with horizontal stripe, and described horizontal stripe one end is hinged with the second hinged seat, and the horizontal stripe other end is provided with through hole, described Through-hole diameter is more than stud diameter and less than handle diameters, and through hole is to being externally provided with the opening that appearance stud passes.Setting by horizontal stripe Put, be not only beneficial to operation, lid can be made to be distributed on horizontal stripe by active force when bearing pressure inside the tank simultaneously, thus be difficult to produce Change shape, improves and seals timeliness, but lid needs complete buckle closure just can realize when the port of body effectively sealing, but horizontal stripe was both Need and hinged seat be hinged, in addition it is also necessary to and screens auricle connects, therefore lid in switching process can buckle closure at the end of body Need higher machining accuracy and assembly precision on mouth, thus add processing request, be unfavorable for reducing processing cost.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is that providing a kind of can reduce assembly precision Quick opening manhole.

For achieving the above object, this utility model provides following technical scheme: a kind of quick opening manhole, including port lid, pipe Body and crossbeam, the opposite sides of described body is respectively equipped with hinged seat and clamping seats, and described clamping seats includes mounting ear, connection Bar and handle, described crossbeam is provided with mounting hole, and described mounting hole is arranged along the length direction of crossbeam, wears in described mounting hole There is the connector for connecting hole lid.

By using technique scheme, port lid is installed on crossbeam by connector, overturns port lid by rotating beam Time, connector can sliding along its length in mounting hole such that it is able to make port lid along the length direction sliding of crossbeam, port lid Skidding distance is regulated such that it is able to ensure that port lid can be kissed with it buckle closure upper tube body end when during sliding Closing, reduce machining accuracy and assembly precision, the buckle closure sealing of port lid but still can be effectively ensured, this structure is easy to add Work, advantageously reduces processing cost.

This utility model is further arranged to: described port lid is provided with fixed strip, and described fixed strip is provided with for connector The installing hole passed.

By using technique scheme, port lid can have fixed strip to realize with crossbeam by extra soldered to be connected, fixes The long enough that bar can be arranged, thus increase the contact area of fixed strip and port lid, desirably prevent port lid and produce when being stressed Deformation, plays the effect of reinforcement.

This utility model is further arranged to: the u-shaped structure of cross section of described fixed strip is arranged.

By using technique scheme, can ensure that crossbeam is effectively connected by connector with fixed strip, the most also side Keep good stability when producing sliding the most between the two, will not be partial to；The most also further enhancing fixed strip as adding Action effect during strong muscle.

This utility model is further arranged to: described crossbeam and fixed strip are equipped with two or more.

By using technique scheme, it is greatly enhanced the structural strength above port lid such that it is able to be prevented effectively from port lid It is deformed.

This utility model is further arranged to: some crossbeams collect setting and clamp block with one near one end of clamping seats Fixing connection, described clamping block is provided with the open slot slipped into for connecting rod.

By using technique scheme, while strengthening port lid sealing timeliness, it is possible to can be real by clamped one time Existing port lid is fixed, it is simple to manhole realizes changing up soon dress, improves service efficiency.

This utility model is further arranged to: be arranged with the pad between handle and clamping block in described connecting rod.

By using technique scheme, pad increases the connection tightness between handle and clamping block, it is to avoid because shaking Move and produce and loosen.

This utility model is further arranged to: described pad is provided with rounding towards clamping block one end, and described clamping block sets There is the arc groove embedded for pad.

By using technique scheme, increase the contact area of pad and clamping block, thus improve handle and act on folder Clamping stability on tight block, stops to loosen.

This utility model is further arranged to: the peripheral edge of described port lid is available for the flange of body port insertion along being provided with.

By using technique scheme, enable port lid flange to be wrapped up by the port of body, hole can be improved The buckle closure sealing of lid, also is able to strengthen the structural strength of port lid simultaneously, desirably prevents port lid stress and produce deformation.

In sum, this utility model has the advantages that the middle part of crossbeam is provided with mounting hole, mounting hole edge The length direction of crossbeam is arranged, and port lid is provided with fixed strip, and fixed strip is provided with the installing hole passed for connector, and port lid passes through Connector realizes being flexibly connected with crossbeam after waist-shaped hole and installing hole, during by rotating beam upset port lid, and connector Meeting sliding along its length in mounting hole such that it is able to making port lid along the length direction sliding of crossbeam, port lid is in sliding During regulate skidding distance such that it is able to ensure port lid buckle closure upper tube body end when can with its coincide, reach fall Low machining accuracy and assembly precision.
