Abstract

The utility model discloses a kind of novel manhole covers, and including crib and the well lid being movably connected on the crib, the crib is equipped with movable chamber, is connected with lever piece in the movable chamber, described lever piece one end is connected with return unit；Be equipped in the movable chamber movable part matched with lever piece one end and with the matched sliding part of the lever piece other end, the sliding part and well lid are inconsistent.The utility model is by tapping movable part, so that sliding part hits well lid, and then boost well lid upwards upwards under lever principle, convenient for opening inspection well cover.

Description

A kind of novel manhole cover

Technical field

The utility model belongs to urban operating mechanism technical field, more particularly, to a kind of novel manhole cover.

Background technology

Current inspection well cover is all completed when opening by using crowbar, but due between well lid and well seat Gap in there are a large amount of soil and fine sand stone, these soil and fine sand stone increase the frictional force between well lid and well seat, This results in inspection well cover and is not easy to be opened.

Utility model content

The utility model a kind of opens easy inspection well cover to overcome the deficiencies of the prior art and provide.

To achieve these goals, the utility model uses following technical scheme：A kind of novel manhole cover, including crib and The well lid being movably connected on the crib, the crib are equipped with movable chamber, lever piece are connected in the movable chamber, Described lever piece one end is connected with return unit；Movable part matched with lever piece one end and and lever are equipped in the movable chamber The part other end matched sliding part is equipped with a position limiting structure, the sliding part and well lid between the movable part and movable chamber It is inconsistent.Since lever piece is inconsistent with movable part and sliding part respectively under the action of return unit, live when being tapped by tool During moving part, lever piece is flipped up under the extruding force effect of movable part, and then generates a upward support force to sliding part, sliding Moving part pushes up well lid under the action of support force, and due to the moment in percussion, the kinetic energy that movable part obtains is larger, Jin Er Under lever principle, sliding part is larger to the impact force of well lid so that the frictional force that well lid can overcome between soil, fine sand stone It moves up, convenient for the unlatching of well lid.

Further, the movable chamber includes first passage, second channel and chamber, the first passage and second channel Respectively with chamber, the lever piece, which may be reversed, to be connected on chamber inner wall, and the movable part is set in first passage, described Sliding part is set in the second channel；First and second channel can play limiting in movable part and sliding part motion process respectively Effect ensures that movable part and sliding part can be inconsistent with the both ends of lever piece respectively always, plays stably conducive to lever construction Working performance.

Further, the crib is equipped with groove, and the first passage is connected with the groove, the movable part one End is extend out in groove；Movable part one end is extended in groove, is not only convenient for tapping movable part by tool, it is thus also avoided that because of work Moving part extend out to crib surface and trips happening for pedestrian.

Further, it may be reversed in the recess sidewall and be connected with capping；By the way that capping is set to be further ensured that crib table The planarization in face, conducive to the passing of pedestrian and vehicle.

Further, the return unit is a spring, and the spring one end is connected on the support element, other end connection In on chamber bottom；Ensure that support element can be inconsistent with movable part and sliding part always under the action of the spring, conducive to support element The performance played stably.

Further, the well lid is equipped with U-lag, may be reversed in the U-lag and is connected with handle；Handle is arranged on U In shape slot, not only facilitate lifting well lid, be additionally favorable for the passing of pedestrian and vehicle.

In conclusion the utility model by tapping movable part, causes sliding part to hit well lid upwards under lever principle, And then well lid is boosted upwards, convenient for opening inspection well cover.

Specific embodiment

In order to which those skilled in the art is made to be better understood from the utility model, below in conjunction with the utility model reality The attached drawing in example is applied, clear, complete description is carried out to the technical scheme in the embodiment of the utility model.

As shown in Figs. 1-2, a kind of novel manhole cover, including crib 2 and the well lid 1 being movably connected on the crib 2, institute 1 side of well lid is stated to be articulated on the crib 2, the crib 2 be equipped with movable chamber, the movable chamber include first passage 21, Second channel 22 and chamber 23,21 upper end of first passage are connected to the upper surface of crib 2, and bottom end is connected with chamber 23, 22 upper end of second channel is connected to well lid lower surface, and bottom end is connected with chamber 23, may be reversed on 23 inner wall of chamber Lever piece 24 is connected with, specifically, the lever piece 24 is a Z-shaped metallic plate, the intermediate position of the metallic plate is hinged on chamber On 23 two side of room, the left side of the lever piece 24 is connected with return unit 28, specifically, the return unit 28 is a spring, institute It states spring one end to be connected on the lever piece, the other end is connected on 23 bottom wall of chamber；It is equipped with and lives in the first passage 21 Moving part 25, the movable part 25 are a metal cylinder, which can be up and down in first passage, the movable part 25 Bottom end and the left side of lever piece 24 it is inconsistent；Sliding part 26 is equipped in the second channel 22, specifically, the sliding part 26 Also it is a metal cylinder, 26 bottom end of sliding part and the right side of lever piece 24 are inconsistent, and top and 1 bottom surface of well lid are inconsistent, Under normal state, metallic plate provides a support force stablized to movable part and sliding part respectively in the effect of spring, is hammered into shape when passing through For son when tools tap the top of movable part, the bottom end of movable part can be pressed down against the left side of metallic plate, pass through lever principle, gold Sliding part can be pushed up by belonging to the right side of plate so that sliding part applies there are one upward thrust well lid, and due to The moment of percussion, the kinetic energy of the acquisition of sliding part is larger, therefore the instant impact that well lid is subject to has overcome well lid with soil, carefully enough Frictional force between sand relatively moves between well lid meeting and crib, so be in the soil between well lid and crib will It falls off, conducive to open manhole cover.

Preferably, the crib 2 is equipped with groove 27, and the first passage 21 is connected with the groove 27, the work The top of moving part 25 is extend out in groove 27, is not only convenient for tapping movable part top by tools such as hammers, it is thus also avoided that activity Part 25 extends to crib surface and is unfavorable for pedestrian and the passing of vehicle happens, further, 27 side wall of groove Upper may be reversed is connected with capping 271, specifically, the capping 271 is a metallic plate, and side is hinged on 27 side wall of groove, During normal state, metallic plate can cover groove, and then convenient for the passing of pedestrian and vehicle.

And for the ease of lifting well lid, U-lag 11 is equipped on the well lid 1, may be reversed and be connected in the U-lag 11 Handle 12.

Obviously, described embodiment is only the part of the embodiment of the utility model, instead of all the embodiments. Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained without making creative work Every other embodiment should all belong to the range of the utility model protection.
