The warning device has simple structure and convenient use, and can warn passengers and vehicles after a well cover is damaged or stolen for avoiding traffic accidents.

Description

A kind of well lid is lost alarming device

Technical field:

The utility model relates to a kind of safety alarm device, and especially a kind of well lid is lost alarming device.

Background technology:

Along with the development in city, the missile silo quantity of various uses constantly increases, and the damaged or stolen phenomenon of well lid is also increasing simultaneously.Well lid itself there is no much value, but the disappearance of well lid, the infringement of causing for vehicle and pedestrian is serious.Although correlation technique department has carried out some technological improvements to well lid, also do not overcome the damaged and stolen problem of well lid effectively.Because of well lid disappearance has uncertainty, be difficult in time find to repair again by administrative department, thus how to guarantee well lid damaged or stolen after traffic safety be a problem demanding prompt solution.

The utility model content:

The utility model provides a kind of well lid to lose alarming device, and it is simple in structure, and is easy to use, can well lid damaged or stolen after, give pedestrian and vehicle with caution, avoided the generation of traffic accident, solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises the U-lag that is connected with manhole cover base, on U-lag, be connected with warning sign by rotating shaft, be set with spring in the rotating shaft in U-lag, spring one end and U-lag are connected, the other end is against the warning sign back side, two lateral wall tops at U-lag are respectively equipped with a limited block, and the positive basifacial of warning sign is resisted against on the limited block.

Two sides at warning sign also scribbles reflectorized material and warning picture.

When the utility model has well lid at well head, warning sign is overwhelmed in well by well lid, and the warning sign extrusion spring is after the well lid breakage or being stolen, well lid has lost the pressure effect to warning sign, warning sign rotates around the axis under the effect of spring force, treats to stop when warning sign and limited block lean, and this moment, warning sign stretched out outer vertical hard the rising of well, remind pedestrian and vehicle to note, can avoid hurting sb.'s feelings and the accident of vehicle damage takes place, improve the image of government, embody harmonious society for the people; Two sides at warning sign also scribbles reflectorized material and warning picture, can strengthen the caution effect at night by light, moonlight.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A portion enlarged drawing among Fig. 1.

Fig. 3 is that B-B among Fig. 1 is to cutaway view Amplified image.

Among the figure, 1, U-lag; 2, rotating shaft; 3, warning sign; 4, spring; 5, limited block.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～3, the utility model comprises the U-lag 1 that is connected with manhole cover base, on U-lag 1, be connected with warning sign 3 by rotating shaft 2, be set with spring 4 in the rotating shaft 2 in U-lag 1, spring 4 one ends and U-lag 1 are connected, the other end is against warning sign 3 back sides, is respectively equipped with a limited block 5 on two lateral wall tops of U-lag 1, and warning sign 3 positive basifacials are resisted against on the limited block 5.

Two sides at warning sign 3 also scribbles reflectorized material and warning picture.Can strengthen the caution effect at night by light, moonlight.

Overwhelmed in well by well lid when warning sign 3 is flat, warning sign 3 extrusion springs 4, after the well lid breakage or being stolen, well lid has lost the pressure effect to warning sign 3, and warning sign 32 rotates under the effect of spring 4 elastic force around the shaft, treats to stop when warning sign 3 and limited block 5 lean, this moment, warning sign 3 stretched out outer vertical hard the rising of well, remind pedestrian and vehicle to note, can avoid hurting sb.'s feelings and the accident of vehicle damage takes place, make traffic safer.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
