Example one

Fig. 1 is the utility model discloses a sewer well lid sectional structure schematic diagram, fig. 3 is the enlarged schematic diagram of A department's structure in fig. 1, it is shown with fig. 3 to combine, this embodiment provides a sewer well lid, is applied to well seat 1, including well lid 2 and coupling mechanism, well seat 1 is used for fixed setting subaerial, and there is the open-ended ring form at 1 position middle part of well seat, and the opening is linked together with the sewer, and well

lid

2 and 1 swing joint of well seat, and well lid 2 set up on well seat 1, well lid 2 can shield well seat 1's opening completely. In this embodiment, be provided with four heavy grooves 6 on the well lid 2, four heavy grooves 6 are around well lid 2's center looks interval arrangement to the interval between per two heavy grooves 6 is all the same, and each heavy groove 6 department all is provided with a coupling mechanism, and well lid 2 and well seat 1 are connected through coupling mechanism. It should be noted that the number of the sinking grooves 6 is arranged according to actual needs, and only the well lid 2 needs to be jacked up by water without side turning, so that at least two sinking grooves 6 need to be arranged.

Fig. 4 is the utility model discloses the structural schematic of connecting rod, it is shown with fig. 1, fig. 3 and fig. 4 to combine, and coupling mechanism specifically includes connecting rod 3 and connecting portion, and connecting rod 3 is including connecting gradually fixed pole cap 31, pole body 32 and pole hook 33, and the diameter of pole cap 31 is greater than the diameter of pole body 32, so the junction of pole body 32 and pole cap 31 forms the second anchor ring, when well lid 2 was by who dashes, the second anchor ring can block the bottom of sink 6 of well lid 2, prevents that the well lid from breaking away from.

Further, a through hole is formed at the bottom of the sink 6, another part of the rod 32 passes through the through hole, a rod hook 33 is fixedly arranged at the bottom end of the rod 32, a hook angle is formed between the rod hook and the rod 32, a connecting part is arranged on the inner circumferential surface of the well lid 2, and the rod hook 33 is detachably hooked with the connecting part. It is noted that the connecting portion may be an ear hook 5 or other member having a notch for hooking with the stem hook 33.

When meetting the well lid when water pressure is too big, ponding will push the well lid 2 upwards open, because ear hook 5 sets up on the interior circumference of well seat 1,

pole hook

33 and 5 looks hookups of ear hook, so connecting rod 3 upward movement not, and well lid 2 can be at upward movement, because the junction of pole body 32 and pole cap 31 forms the second anchor ring, can prevent breaking away from of well lid 2, wait to the water pressure decline under well lid 2, well lid 2 will be covered once more under the effort of self gravity and establish on well seat 1, realize the automatic re-setting of well lid 4, and the device has good practicality.

Further, please continue to refer to fig. 5, in the normal connection process of the well lid 2 and the well base 1, or in the process that the well lid 2 is driven by the water pressure to move the rod body 32 of the connecting rod 3 upward, in order to avoid the dirt in the well from permeating into the sink groove 6 from the connecting gap between the rod body 32 and the through hole, and further cause the relevant parts in the sink groove 6 to be soaked, corroded, etc. by the sewage, the life cycle of the relevant parts is shortened to generate unnecessary maintenance cost.

As an embodiment of the sealing mechanism, the sealing mechanism may be a groove 14 which is provided on the inner wall of the through hole and has a ring shape, the groove 14 is provided in an embedded manner on the inner wall of the through hole, and a flexible sealing ring, such as a rubber ring having a contracting or elastic function, is provided in the groove 14, so that the sealing ring is provided in the groove and seals the contact between the shaft 32 and the through hole when the shaft 32 passes through the through hole.

As another embodiment of the sealing mechanism, the sealing mechanism may be a rubber patch that is stuck on the inner wall of the through hole and has a shrinking or elastic function, and the rubber patch is compressed when the shaft 32 passes through the through hole to seal the contact between the shaft 32 and the through hole.
