Description
Technical field
The utility model relates to a kind of well lids, refer in particular to a kind of bolt interlocking formula well lid.
Background technique
Well lid prevents people or object from falling for covering road or family's middle-deep well.It include well lid and cover seat of manhole, lid
Well seat is fixed on well head by cement slurry, and well lid is fixed on cover seat of manhole by lock solid structure；For well lid and cover seat of manhole two
Person's lock solid structure problem has developed the patent document CN106436769A as disclosed on February 22nd, 2017, is related to a kind of knot
The high well lid of structure intensity；Wherein locked between well lid and cover seat of manhole by drum connector, forms first party on the well lid
The second rectangular through-hole section is formed in shape through-hole section, cover seat of manhole；The first rectangular through-hole section relative on two inner walls respectively at
Type has the first fin with spacing, and it is logical that at least one end of two first fins forms first in the first rectangular through-hole section
Slot, the spacing between two first fins form the first passage being connected to the first through slot；The second rectangular through-hole section pair
Two first fins are answered to form two second fins, at least one end of two second fins is in the second rectangular through-hole section
The second through slot is formed, and the spacing between two second fins forms the second channel being connected to the second through slot；The drum
Connector has the first transverse part being snapped in above the first fin, the second transverse part being snapped in below the second fin and connection
First transverse part and the second transverse part and it is placed in first passage, the first vertical interconnecting piece in second channel, this locking knot
Structure, which facilitates, locks together well lid and cover seat of manhole；Because between the first transverse part and the second transverse part of drum connector
Away from be it is fixed, the spacing between the first transverse part and the second transverse part can not be adjusted；If the first transverse part and second is laterally
The spacing in portion is equal to or less than the spacing between the top surface of the first fin and the bottom surface of the second fin, and drum connector is inserted with regard to bad
It sets and is buckled in the first fin and the second fin, install that there are problems；If the spacing of the first transverse part and the second transverse part is big
Spacing between the top surface of the first fin and the bottom surface of the second fin, there are gaps between each component；Since well lid is assembled in
On road, vibration is rolled by vehicle for a long time, the gap between each component results in mutual generating collision, collides for a long time each
Modular construction is easily broken off damage, and then influences the fastness of well lid mounting structure.
In view of this, the designer, which is directed in said structure design not attain, improves caused many missings and inconvenience, and
Deeply design, and actively research improvement has a fling at and develops and design this case.

Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
It please refers to Fig.1 to Fig.3, the utility model discloses a kind of bolt interlocking formula well lid comprising has well lid 1, well lid
The bolt 3 of seat 2 and multiple connection well lids 1 and cover seat of manhole 2, the well lid 1 are provided with multiple deep gouges 11 and the slot through deep gouge 11
The wears groove 12 of bottom wall, the corresponding wears groove 12 of the cover seat of manhole 2 are provided with screw hole 21, and the bolt 3 has bolt head 31 and screw rod 32,
The screw rod 32 passes through 12 interlockings of perforation in screw hole 21 and bolt head 31 is placed on deep gouge 11 and locks well lid 1 and cover seat of manhole 2
It is connected together.
The utility model well lid during installation, needs first to close the lid of well lid 1 above cover seat of manhole 2, and by wears groove 12 and spiral shell
Hole 21 is aligned, and bolt 3 is then passed through wears groove 12 and is locked in screw hole 21, bolt head 31 is placed on deep gouge 11,32 end of screw rod
Lock with cover seat of manhole 2, and then well lid 1 and cover seat of manhole 2 are locked together；The utility model can lock screw hole 21 by bolt 3
Depth carry out the tautness that adjustment bolt head 31 is placed on deep gouge 11, improve bolt 3 well lid 1 and 2 interlocking of cover seat of manhole is secured
Property, it is easy to assembly and be easily installed adjustment.
The wears groove 12 of the utility model is arranged in the middle part of the groove bottom wall of deep gouge 11, and the length and width of the wears groove 12
Degree is greater than the diameter of the screw hole 21；It can be adjusted on length and width direction, facilitate wears groove 12 and screw hole 21 to be aligned, assembling is more
It is convenient.
The screw hole 21 of the utility model runs through the two sides up and down of the cover seat of manhole 2, when bolt 3 locks screw hole 21 deeply
