Abstract
The utility model discloses an anti-falling type well lid and belongs to the technical field of well lids. The anti-falling type well lid aims to achieve the technical aim that after a top cover is stolen or is jacked open by overhigh water pressure in a sewer, pedestrians can be prevented from falling into the sewer. According to the technical scheme, the anti-falling type well lid comprises the top cover, a protective grate and a base, wherein the base and the top cover are hinged together, the outer diameter of the protective grate conforms to the inner diameter of the base, and the protective grate is movably clamped on the inner wall of the base. The protective grate is arranged inside the base and clamped on the base through locking clamps on the base; when water pressure in the sewer is overhigh, the top cover will be jacked open, and due to the fact that the protective grate is arranged in the well lid, the pedestrians can walk on the protective grate and will not fall into the sewer.
Description
Technical field
A kind of dropproof type well lid of the utility model, belong to the well lid technical field.
Background technology
Well lid is widely used in urban construction, and the top cover of common well lid just is placed on base, and due to precipitation or block up while causing water pressure in sewer pipe larger, top cover is often backed down, and when the pedestrian walks out-of-dately, easily drops in sewer, causes danger.In addition, top cover is without any antitheft measure, be easy to stolen, and, between the contact surface of top cover and base without any padded coaming, when top cover was pressed in pedestrian or driving, the collision between top cover and base can be sent noise, affects people's life.
The utility model content
The utility model overcomes the deficiency that prior art exists, technical problem to be solved be to provide a kind of in due to sewer hydraulic pressure cross that senior general's top cover backs down or top cover stolen after, can prevent that the pedestrian from falling into the well lid of sewer.
In order to solve the problems of the technologies described above; the technical scheme that the utility model adopts is: a kind of dropproof type well lid, comprise top cover, protection comb and base, and base and top cover are hinged; the external diameter that described protection is combed and the internal diameter of base adapt, and protection comb active card is contained on the inwall of base.
The inwall of described base is provided with the boss that a circle support protection is combed; uniformly above described boss be provided with a plurality of locking clamps; uniformly on the circumference that described protection is combed be provided with a plurality of grooves that match with locking clamp, and the protection comb is arranged between boss and locking clamp by screwing.
Be provided with rubber strip on the contact surface of described top cover and base.
Described top cover, protection are combed and base is the ductile iron cast structure.
Be provided with opening groove on described base.
The beneficial effect that a kind of dropproof type well lid of the utility model compared with the existing technology had is.
1, the utility model is provided with the protection comb in the inside of base; protection is combed and is stuck on base by the locking clamp on base; when the hydraulic pressure in sewer is excessive; the hydraulic pressure of sewer backs down top cover, owing to being provided with protection in well lid, combs, and the pedestrian can walk on protection is combed; do not have the danger dropped in sewer; and the gap that current can be combed by protection is discharged to the outside of sewer, reduce the hydraulic pressure in sewer.
2, top cover of the present utility model and base are hinged, top cover is had good theftproof, and opening and closing flexibly.
3, the utility model is equipped with rubber strip on the contact surface of top cover and base, avoids top cover and base collision and the generation noise.
4, the utility model is provided with opening groove on base, when needs are opened top cover, crowbar is stretched in opening groove, prizes top cover and gets final product, simple to operation.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is base in the utility model.
In figure: 1 is top cover, and 2 comb for protection, and 3 is base, and 4 is rubber strip, 5 locking clamps, and 6 is groove, 7 is opening groove.
The specific embodiment
As shown in Fig. 1-2; a kind of dropproof type well lid of the utility model, comprise top cover 1, protection comb 2 and base 3, and base 3 is hinged with top cover 1; the external diameter of described protection comb 2 and the internal diameter of base 3 adapt, and protection comb 2 active card are contained on the inwall of base 3.
The inwall of described base 3 is provided with the boss of a circle support protection comb 2; uniformly above described boss be provided with a plurality of locking clamps 5; described protection is combed and uniformly on 2 circumference is provided with a plurality of grooves 6 that match with locking clamp 5, and protection comb 2 is arranged between boss and locking clamp 5 by screwing.
Be provided with rubber strip 4 on the contact surface of described top cover 1 and base 3.
Described top cover 1, protection comb 2 and base 3 are the ductile iron cast structure.
Be provided with opening groove 7 on described base 3.
Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing:
In the utility model, be provided with a plurality of grooves 6 on the circumference of protection comb 2, during installation, the locking clamp 5 that groove 6 is aimed on base 3 inwalls, protection is combed 2 to be fallen on its boss of support, to protect again the angle of 2 rotations of combing, like this, protection is combed and 2 just to be installed between boss on base 2 inwalls and locking clamp 5, when the hydraulic pressure in sewer is excessive, even the hydraulic pressure of sewer backs down top cover 1, protection also is installed in the utility model and combs 2, the pedestrian can walk on protection comb 2, do not have the danger dropped in sewer, and, current can be discharged to the outside of sewer by comb 2 gap of protection, reduce the hydraulic pressure in sewer, simultaneously, top cover 1 of the present utility model is hinged with base 3, make top cover 1 there is good theftproof, and opening and closing flexibly, and, between top cover 1 and base 3, rubber strip 4 is installed, avoid top cover 1 and base 3 collisions and produce noise, when top cover 1 needs to open, the utility model is provided with opening groove 7 on base 3, crowbar is stretched in opening groove 7, prizing top cover 1 gets final product, simple to operation.
