Description

A kind of anti-lost inspection shaft mouth and inspection shaft lid

Technical field

The utility model is used on the road in city, and the inspection shaft mouth is embedded on the well head of road sewer, and the inspection shaft lid will be automatically locked with the inspection shaft mouth after inspection shaft covers on the inspection shaft mouth, rotates an angle, thereby has reached anti-lost purpose.

Background technology

Manhole cover on the road of city does not all have self-locking mechanism at present, covering the back just is pressed on the inspection shaft mouth by its deadweight, this is easy to by the people inspection shaft lid be stolen, when vehicular traffic was pressed the inspection shaft lid sometimes, also the inspection shaft lid can have been seized and has lost, thereby cause the uncovered inspection shaft, this causes great danger to passing vehicle and pedestrian.Often have at present because of the stolen pedestrian of making of inspection shaft lid falls into report in the inspection shaft, pedestrian's life is constituted great prestige association.The utility model designs at this phenomenon.

Summary of the invention

The purpose of this utility model is that a kind of anti-lost inspection shaft mouth and inspection shaft lid is provided at above-mentioned weak point.

Technical solution of the present utility model is: a kind of anti-lost inspection shaft mouth and inspection shaft lid, comprise inspection shaft mouth and inspection shaft lid, and it is characterized in that: be provided with two breach on the seam of the support well lid in the inspection shaft mouth, be provided with a location boss in indentation, there; Corresponding inspection shaft mouth indentation, there is respectively equipped with two " [" type hooks on the base of inspection shaft lid.

Can be in that " inboard of [" type hook be provided with a cylinder, and a thrust block is installed on cylinder in the technical solution of the present utility model.

The utility model provides anti-lost inspection shaft mouth and the inspection shaft lid of using on a kind of urban road, it is installed on the sewer mouth of urban road, this inspection shaft mouth and inspection shaft lid are owing to be provided with self-locking device, when inspection shaft covers on the inspection shaft mouth, the inspection shaft lid will be automatically locked with the inspection shaft mouth after rotating an angle, thereby prevented losing of inspection shaft lid well, eliminated the unsafe factor that causes of losing effectively, reached anti-lost purpose pedestrian and vehicle because of the inspection shaft lid.

Description of drawings

Fig. 1 is the structural representation of the utility model inspection shaft mouth; Fig. 2 is the A-A sectional drawing of Fig. 1; Fig. 3 is the B-B sectional drawing of Fig. 1; Fig. 4 is the structural representation of the utility model inspection shaft lid; Fig. 5 is the C-C section of Fig. 4; Fig. 6 is the D-D section of Fig. 4.

The specific embodiment:

Be provided with two breach, 1,2 (see figure 1)s on the seam 3 of the support inspection shaft lid in the inspection shaft mouth, 1 place is provided with positioning boss 4 at breach; Breach 1,2 places at the corresponding inspection shaft mouth in the base of inspection shaft lid are provided with two " [" type hook 5,6 (see figure 5)s.

" [" type hook 5 alignment notch 1 that during lid inspection shaft lid inspection shaft covered, " after [" type hook 6 alignment notch 2 cover, the inspection shaft lid just is buckled on the seam 3 of inspection shaft mouth, and " claw hook of [" type hook then stretches to the below of seam 3 by two breach 1,2 on the seam 3 of inspection shaft lid.With special tool well lid is clockwise rotated, forward always that " [" type hook 6 is by till the last positioning boss 4 to; Because well lid rotate that the seam 3 of back inspection shaft mouth is stuck in just in time that inspection shaft covers " centre of [" type hook makes inspection shaft lid and inspection shaft interruption-forming one, thus the inspection shaft lid can not at will uncover, thereby reach anti-lost purpose.In the time of need opening well lid, must well lid be rotated counterclockwise to original position with special tool and just can open.

In the inboard of hook 5, be provided with a cylinder 7 in addition, on cylinder 7, adorn short thrust block 8 (see figure 6)s of the long end of one one end.

What thrust block 8 was long when covering well lid one corrects and rests on the positioning boss 4, clockwise rotate well lid with special tool, thrust block 8 long ends just can leave positioning boss 4 is in positioning boss 4 by the deadweight whereabouts side, when well lid being rotated counterclockwise with special tool, thrust block 8 just can push up the side of positioning boss 4, cause the inspection shaft lid can not go to original position,, cover and inspection shaft mouth interlocking purpose thereby reach inspection shaft so the inspection shaft lid can't be uncovered; Open well lid, also will thrust block 8 long ends be lifted with (see figure 1) in the circular hole of a special key from the well lid, well lid just can be opened to original position in the last plane that makes it to be higher than positioning boss 4 rotating well cover again.

The utility model covers a little at former inspection shaft mouth and inspection shaft and changes, and need not increase cost, just can reach the anti-antitheft purpose of losing, and has improved the safety that vehicle and pedestrian pass through on the road of city greatly.

Preferred embodiment of the utility model as mentioned above, " [" type hook, as required, " [" type hook and corresponding breach can be made as more than two places to be provided with two places.
