Abstract
The utility model discloses a well lid seal structure and relates to a seal structure. The well lid seal structure comprises a well lid and a well seat. A lock hole is arranged in the well lid and a seal strip is arranged between the well lid and the well seat. A locking device is arranged to achieve firm contact between the well lid and the seal strip of the well seat and comprises a lifting ring, a locking piece, a press spring, a rubber gasket and a lifting lug. The locking piece is a cone-shaped body. A buckle used to be locked tightly with the well seat is arranged at the bottom of the locking piece. The lifting ring is connected with the top end of the locking piece. The lifting lug is a hollow cylinder and provided with ring-shaped clamping sides on the outer and inner surfaces. The clamping side on the inner surface of the lifting lug is provided with the rubber gasket. The press spring is connected with the locking piece and the rubber gasket. The locking device is arranged in the locking hole. A groove, corresponding to the ring-shaped clamping side on the outer surface of the lifting lug, is arranged in the inner surface of the locking hole. The well lid seal structure is good in sealing effect and can effectively prevent water from accumulating in a well.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, is specifically related to a kind of well lid hermetically-sealed construction.
Background technology
Traditional well lid hermetically-sealed construction mainly is comprised of well lid and well seat, and hermetically-sealed construction only relies on the contact surface of well lid, well seat self to play certain sealing function, if contact surface out-of-flatness or the slit is arranged just causes seal failure, and the easy phenomenon of ponding in the well
Rely on sealing joint strip to seal between well lid of the present invention and the well seat, and increased locking device, well lid is fully contacted with weather strip on the well seat, reach the effect of sealing.The elastic module that has demonstrated fully rubber among the present invention is large, the characteristic that shape is easily replied.Make well lid open the characteristics that repeatedly still can reach good sealing effect.
Summary of the invention
The utility model provides a kind of well lid hermetically-sealed construction, and the prior art sealing is poor to solve, the easy problem of ponding in the well.
The utility model comprises well lid and well seat, solving the technical scheme that its technical problem adopts is that keyhole is set on the well lid, between well lid and well seat, weather strip is set, also increase the locking device that well lid and weather strip on the well seat are fully contacted, locking device comprises suspension ring, locking member, stage clip, rubber sheet gasket and hanger, locking member is cone, the locking member bottom arranges the buckle that is used for the locking of well seat, suspension ring are connected with the locking member top, hanger is hollow cylindrical, the hanger surfaces externally and internally is provided with annular edge, on the hanger inner surface annular edge rubber sheet gasket is set, stage clip links to each other with rubber sheet gasket with locking member, and locking device is arranged in the keyhole, and the keyhole inner surface is provided with and the corresponding groove of hanger external surface annular edge.
Above-mentioned rubber sheet gasket is hollow ring.
The beneficial effects of the utility model are to carry out well lid sealing with weather strip, and locking device makes well lid fully contact with weather strip on the well seat, and the enhanced leaktightness effect has prevented the problem of easy ponding in the well effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is generalized section of the present utility model;
Fig. 2 is the utility model partial structurtes enlarged diagrams.
1 well lid, 2 well seats, 3 locking members, 4 rubber sheet gaskets, 5 hangers, 6 suspension ring, 7 weather strips, 8 stage clips, 9 keyholes, 10 grooves, 11 buckles, 51 annular edges among the figure.
The specific embodiment
Such as Fig. 1, shown in Figure 2: a kind of well lid hermetically-sealed construction, comprise well lid 1 and well seat 2, keyhole 9 is set on the well lid 1, between well lid 1 and well seat 2, weather strip 7 is set, also increase the locking device that well lid 1 and weather strip 7 on the well seat 2 are fully contacted, locking device comprises suspension ring 6, locking member 3, stage clip 8, rubber sheet gasket 4 and hanger 5, locking member 3 is cone, the buckle 11 with 2 lockings of well seat is not put in locking member 3 bottoms, suspension ring 6 are connected with locking member 3 tops, hanger 5 is hollow cylindrical, and hanger 5 surfaces externally and internallies are provided with annular edge 51, and rubber sheet gasket 4 is hollow ring, be placed on the hanger 5 inner surfaces annular edge 51, stage clip 8 links to each other with rubber sheet gasket 4 with locking member 3, and locking device is arranged in the keyhole 9, and keyhole 9 inner surfaces are provided with and hanger 5 external surfaces annular edge 51 corresponding grooves 10.
During use, suspension ring 6 are connected with locking member 3, and stage clip 8 can produce deformation, make locking member 3 be easy to rotational lock, suspension ring 6 drive locking member 3 makes stage clip 8 produce deformation, suspension ring 6 90-degree rotations, make the buckle 11 of locking member 3 bottoms stuck with the well seat, thereby play the locking effect; During open manhole cover 1, suspension ring 6 90-degree rotations separate locking member 3 lower snap 11 well seats, on carry locking member 3, it is connected with hanger 5, get final product open manhole cover 1.
