Description
Technical field
The utility model belongs to well lid technical field, more particularly, to a kind of dropproof manhole cover structure.
Background technique
Inspection shaft be the power supply for Urban Underground infrastructure, water supply, draining, blowdown, communication, cable television, gas pipe,
Public lighting circuit etc. maintenance and it is easy for installation and be arranged.It is laid and is needed due to pipeline, inspection shaft can be located at the road surface of size road
On, at inspection shaft well head be arranged well lid, inspection shaft by well lid close, prevent pedestrian be strayed into or accident back drop in.It needs
To in inspection shaft pipeline or equipment overhaul when, open well lid, inspection personnel, which goes into the well, maintenance or passes through specific purpose tool
It is overhauled.
In the prior art, there are two types of mounting means for existing well lid:
1. top cover is rest directly upon on pedestal, when causing the hydraulic pressure in sewer pipe larger due to precipitation or congestion, top
Lid is often opened, and when pedestrian walks out-of-date, is easy to drop into sewer, be caused danger.
2. anti-drop net is used, and the service life of anti-drop net is short, the case where personal injury easily occurs.
Utility model content
The purpose of the utility model is to provide a kind of dropproof manhole cover structure, the well lid of the manhole cover structure is mounted on cover seat of manhole
So that L shape fixture block and well lid is blocked cover seat of manhole by rotating well cover after upper, prevent well lid from being opened or being taken away easily, promotes safety
Property.
The technical solution of the utility model is: a kind of dropproof manhole cover structure, it includes pit shaft, well lid, cover seat of manhole, spy
Sign is that the well lid is rounded and edge is resisted against on cover seat of manhole, and several L shape fixture blocks, the well are equipped with below well lid
Cage is in circular ring shape and is fixed in pit shaft, and cover seat of manhole edge is fixed on shaft in wall, is provided on cover seat of manhole several for L shape card
The groove that block passes through, cover seat of manhole inlay card is between L shape fixture block and well lid when well lid rotates.
Firstly, well lid is placed on cover seat of manhole, the L shape fixture block below well lid is set to pass through groove, then well lid is rotated one
Determining angle makes cover seat of manhole inlay card between L shape fixture block and well lid, and well lid is enable to fix, and prevents from being opened or be taken away easily,
Security performance gets a promotion, and in inspection shaft installation and maintenance process, only need to circumferentially rotate well lid, can make well lid and cover seat of manhole
Separation, it is convenient for disassembly and assembly.
Further, the triangle limited block of several support cover seat of manhole is fixed with inside the pit shaft.Triangle limited block is used
In support cover seat of manhole, support force is further strengthened.
Further, the triangle limited block is located at two sides below groove.Position-limiting action is risen to the steering of well lid.
Further, there are two groove tools, there are two L shape fixture block tools, and L shape fixture block and groove location quantity are homogeneous
It is corresponding.
Further, the well lid upper surface has knob.Knob facilitates user to rotate and lift well lid.
Further, the corresponding well lid upper surface of L shape fixture block has arrow logo one, the corresponding pit shaft side of groove
Edge has arrow logo two.Arrow logo one and arrow logo two facilitate the installation and dismounting of well lid, and well lid upper surface is had
Arrow logo one and pit shaft edge have the alignment of arrow logo two i.e. mountable or pull out well lid, and the installation Later Zhou Dynasty, one of the Five Dynasties makes to rotating well cover
Arrow logo one and arrow logo two misplace, and well lid is fixed on cover seat of manhole by L shape fixture block and will not be opened.
The advantages of this dropproof manhole cover structure, has:
L shape fixture block and well lid is set to block well lid by rotating well cover afterwards 1. the well lid of the manhole cover structure is mounted on cover seat of manhole
Seat, prevents well lid from being opened or being taken away easily, promotes safety.
2. installation and dismounting that arrow logo one and arrow logo two facilitate well lid.

Specific embodiment
As shown in Figure 1-3, the technical solution of the utility model is a kind of dropproof manhole cover structure, it includes pit shaft 1, well lid
4, cover seat of manhole 5, which is characterized in that the well lid 4 is rounded and edge is resisted against on cover seat of manhole 5, is equipped with below well lid 4 several
L shape fixture block 6, the cover seat of manhole 5 is in circular ring shape and is fixed in pit shaft 1, and 5 edge of cover seat of manhole is fixed on 1 inner wall of pit shaft, well
Several grooves 7 passed through for L shape fixture block 6 are provided on cage 5,5 inlay card of cover seat of manhole is in L shape fixture block 6 and well lid 4 when well lid 4 rotates
Between.
The triangle limited block 2 of several support cover seat of manhole 5 is fixed with inside the pit shaft 1.Triangle limited block 2 is used to support
