CN2161643Y - Safety theft-proof sewage well cover - Google Patents

Abstract

The utility model relates to a well cover for sewage discharge, comprising a well cover and a well seat. At present, well covers in the urban road service installation are often stolen or pressed over to cause accidents. The utility model relates to a well cover which can be locked for overcoming the disadvantages. When in use, only the well cover is rotated. Top wires on the upper side of the well cover can automatically fastened by the convex table of the well seat, which enables the well cover not to be taken out. Thus, theft-proof and turning-proof purposes are obtained. The utility model can be widely used on the top sides of sewage or water well mouths.

Description

Safety theft-proof sewage well cover

The utility model belongs to the communal facilities of a kind of sewage effluent in the urban road, particularly a kind of well lid that is used for the shutoff sink hole.

Continuous development along with urban traffic, road construction constantly increases, sewage emissions is again a vital thing in the road, but cesspool cover is but lost often, cause the pedestrian to fall in the well, casualty accident takes place, particularly night the street lighting deficiency the road surface problem more serious, according to reports, 6000 of cesspool covers were lost in certain city altogether at 92 years 1 year, more than 40 ten thousand yuan of direct economic losses, well lid lose the safety that is directly threatening people's lives, but can prevent that at present the device that well lid is lost from yet there are no report.

The purpose of this utility model is exactly that provide in order to overcome above-mentioned shortcoming a kind of can lock the cesspool cover that hole cover can play antitheft anti-canting.

Implementation of the present utility model is:

This device is to have increased an anti-picking device on traditional cesspool cover basis, during manufacturing, at first casts out three convex platforms on the inwall of garden shape well seat; Corresponding site at well lid also casts out three onesize boss, at this fixing a slice steel plate more respectively above boss, after well lid is put into the well seat, as long as rotary well cover a little clockwise, this moment, well lid and well toilet can be blocked by steel plate, make the well lid can not be up and down, the utility model takes out well lid for preventing any rotary well cover of unrelated person in the well seat, special in the well lid top by having put locking device, as not utilizing special instrument, well lid is taken out in the well seat or make the well lid upset, thereby realize the task of the utility model proposes.

The utility model compared with prior art has characteristics simple in structure, novel, thus since well lid have locking device played antitheft, anti-effect of rolling, both safety in the use is difficult for upset again, can not cause the personal safety accident.

The utility model is provided by following examples:

Below in conjunction with accompanying drawing the utility model is described further

Accompanying drawing 1 safe antitheft cesspool cover principle schematic

Accompanying drawing 2 safe antitheft cesspool cover locking device principle schematic

Accompanying drawing 3 safe antitheft cesspool cover retaining mechanism principle schematic

A place enlarged diagram in the accompanying drawing 4 safe antitheft cesspool cover principle schematic.

This device is made up of well lid 1, well seat 2, shaft-cup 3, Xiao Zi 4, convex step 5, axle 6, jackscrew 7, pick-proof steel plate 12.

During manufacturing, at first on the inwall of the sink hole seat 2 that is cast, cast out equally distributed three convex shape steps 5, also cast three convex shape steps (shown in Figure 1) accordingly above the well lid 1 and then each fixes a pick-proof steel plate 12(Fig. 3 with bolt below three boss of well lid 1) at circle, during use, earlier well lid 1 is put into above the well seat 2, well lid then turns clockwise, the anti-skid plate 12 that is fixed on above the well lid just in time is positioned at below the well seat boss, at this moment, well lid and well seat are fixed together, play anti-turn over, antitheft effect.

During convex step on make well seat 2, one of them step will be made into " ┌ " shape.The effect of this step is when the jackscrew of well lid top forwards latched position to, and well lid just can not continue to do to have turned clockwise, and indicate that well lid locked complete this moment.

When using locking device to open well lid, to turn on shaft-cup 3 with special spanner earlier, use special spanner other end axis of rotation 6 then, at this moment, jackscrew 7 above the well lid is also and then to being rotated counterclockwise, the steel plate 12 of well lid bottom leaves the boss of well seat bottom, and at this moment well lid just can be moved away from the sewage well head.For preventing that well lid from arbitrarily prying open, be provided with a shaft-cup 3 above the well lid, get up regulating axle 6 shutoff that well lid rotates, so just can't come rotary well cover and take out it by axle.Adopt the frame mode of this dual fail-safe can guarantee safe in utilization.

Claims (3)

1, a kind of well lid that is used for the sewage well head is made up of well lid 1 and well seat 2, it is characterized in that under the described well lid and be uniform-distribution with three convex shape steps 5 above the well seat inwall, below three boss of well lid, respectively be fixed with an anti-skid plate 12, on well lid, be provided with a jackscrew 7 with bolt.

2, cesspool cover according to claim 1; It is characterized in that having above the well lid locking device, this device is made up of a shaft-cup 3 and jackscrew 7.
