Abstract
An anti-theft combination of an inspection well cover and an inspection well base comprises the inspection well cover with water falling holes and the inspection well base. The inspection well cover is placed in the inspection well base. The lower end face of the inspection well cover extends downwards to form a cylinder. The lower end of the outer circular face of the cylinder extends downwards to form a plurality of limiting blocks. The inner wall face of the inspection well base is provided with a plurality of limiting stop rings extending inwards from top to bottom. Each limiting stop ring is provided with a notch corresponding to one limiting block. The notches in the limiting stop rings are arranged in a stagger mode. The limiting blocks on the inspection well cover and the radial limiting stop rings in the inspection well base are in axial limiting fit. A code is arranged on the inspection well cover, an opening password is preset, the position of the inspection well cover is recorded, and then data of the password and the position can be stored. When the inspection well cover needs to be opened, the inspection well cover can be rapidly opened only by checking the stored data. The anti-theft combination of the inspection well cover and the inspection well base is simple in structure and convenient to install, the inspection well cover is difficult to move without the opening password or an opening method, the inspection well cover can be effectively prevented from being lost, and the market prospects are wide.
Description
Technical field
The utility model relates to the municipal engineering technical field, especially a kind of antitheft inspection well cover and inspection well seat.
Background technology
The urban pavement inspection well cover mostly is the cast iron manufacture, because of without locking device, sewer is anti-during often because of stolen or heavy rain flows that impacting offs normal loses for inspection well cover, without the inspection shaft of inspection well cover, pedestrians and vehicle are caused to potential safety hazard, and the personal injury accident that inspection shaft causes often has generation.
Summary of the invention
The utility model provides a kind of antitheft inspection well cover and inspection well seat, the anti-problem of offing normal and losing of impacting that flows of sewer while having solved the stolen or heavy rain of inspection well cover.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of antitheft inspection well cover and inspection well seat, comprise inspection well cover and inspection well seat with water falling hole, inspection well cover is placed in inspection well seat, it is characterized in that: the lower surface of described inspection well cover is extended with cylinder downwards, and the periphery lower end of cylinder is outward extended with a plurality of limited blocks; The internal face of described inspection well seat a plurality of spacing back-up rings that from top to bottom extended internally, be equipped with the breach corresponding with limited block on each spacing back-up ring, the breach interlaced arrangement on spacing back-up ring; Limited block on described inspection well cover coordinates with the radially spacing back-up ring formation axial limiting in inspection well seat.
To the further improvement of technique scheme, the upper surface of described inspection well cover is provided with the coding uniform along circumferential edges, and the English alphabet of coding projection and numeral form; The upper surface of described inspection well seat be provided with the projection to the code triangle body.
Beneficial effect: the utility model is compared with inspection well seat with traditional inspection well cover, because having changed the structure of inspection well cover and inspection well seat, make both can carry out the axial limiting cooperation, thus the anti-problem of offing normal and losing of impacting that flows of sewer while having solved the stolen or heavy rain of inspection well cover; Coding is set on inspection well cover, after being scheduled to open password and recording its position, these data storings can be got up, when needs are opened certain inspection well cover, as long as check the data of storage, just can open rapidly inspection well cover.The utility model is simple in structure, easy for installation, and does not know to open password and the very difficult mobile well lid of method, can effectively prevent the loss of well lid, has more wide market prospects.
The accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Fig. 2 is the inspection well cover structural representation in the utility model.
Fig. 3 is the inspection well seat sectional view in the utility model.
In figure, 1 is inspection well cover, the 2nd, and inspection well seat, the 3rd, cylinder, the 4th, limited block, the 5th, spacing back-up ring, the 6th, breach, the 7th, coding, the 8th, to the code triangle body.
The specific embodiment
As shown in Figure 1,2 and 3, a kind of antitheft inspection well cover and inspection well seat, comprise inspection well cover 1 and inspection well seat 2 with water falling hole, and inspection well cover 1 is placed in inspection well seat 2, the lower surface of described inspection well cover 1 is extended with cylinder 3 downwards, and the periphery lower end of cylinder 3 is outward extended with two limited blocks 4; The internal face of described inspection well seat 2 three the spacing back-up rings 5 that from top to bottom extended internally, be equipped with the breach corresponding with limited block 46 on each spacing back-up ring 5, breach 6 interlaced arrangement on spacing back-up ring 5; Limited block 4 on described inspection well cover 1 coordinates with the radially spacing back-up ring 5 formation axial limitings in inspection well seat 2.The upper surface of described inspection well cover 1 is provided with the coding 7 of circumference uniform distribution, encodes 7 protruding English alphabet and numeral, to consist of; The upper surface of described inspection well seat 2 be provided with the projection to code triangle body 8.
Using method of the present utility model: in the coding on inspection well cover, optional one of them English alphabet and numeral are made as the indication code that reads password.Such as selecting " k ", " L " or " 8 " in English alphabet and numeral to read indication code as password.During installation, first use special tool to go deep in two water falling holes on inspection well cover, inspection well cover is placed in inspection well seat, limited block on inspection well cover can not move down because of stopping of the spacing back-up ring in inspection well seat, need the rotation inspection well cover, make corresponding to the code triangle body with on inspection well seat of English alphabet " k " on inspection well cover, now, limited block falls in the breach on the first spacing back-up ring and moves down.Limited block can not move down because of stopping of the second spacing back-up ring in inspection well seat, needed the rotation inspection well cover, made corresponding to the code triangle body with on inspection well seat of English alphabet " L " on inspection well cover, and now, it is interior and move down that limited block falls into breach on the second spacing back-up ring.Limited block can not move down because of stopping of the 3rd spacing back-up ring in inspection well seat, needed the rotation inspection well cover, made corresponding to the code triangle body with on inspection well seat of numeral " 8 " on inspection well cover, and now, it is interior and move down that limited block falls into breach on the 3rd spacing back-up ring.When the limited block on inspection well cover is worn to the lower end of inspection well seat, more arbitrarily angled rotate inspection well cover, the breach on limited block and spacing back-up ring is staggered, thereby limited block is coordinated with spacing back-up ring axial limiting; The opening process of inspection well cover is just in time contrary with the sequence of coden of put procedure.In the situation that do not know to open password and method, be difficult to mobile inspection well cover, can effectively prevent the loss of inspection well cover.
