Abstract

The utility model relates to a well cover, particularly a well cover which is suitable for being used for the maintenance of telecommunication cables or sewage pipelines on a street. The utility model is composed of a well cover and a well seat. The well cover and the well seat are connected by a rotary shaft. A hook shape 14 is presented on the side surface of a locking handle. A through hole is arranged on the well cover. The rotary shaft is arranged in the through hole. The upper end part of the rotary shaft is in a triangle or a regular polygon, and the lower end part of the rotary shaft is a hook shape 15 which is matched with the hook shape 14 on the locking handle. At least four circular holes 5 are uniformly distributed on the well seat. The utility model has the advantages and obvious technical effects that only a rotary shaft of a locking hook is rotated, a rotary shaft of the locking handle can be rotated, the corresponding safe performance of the well cover is ensured. In addition, due to the fact that at least four circular holes 5 are uniformly distributed on the well seat, the well seat and a base are firmly connected together by bolts, or steel ribs and concrete, all components are not easily damage components, therefore the integral safe well cover is firm and durable. Due to the fact that both ends of the well cover are fixed, the stability of the well cover is good, the well cover is not easy to steal or to press to be turned by an automobile and the well cover has good safe performance. Due to the fact that the opening and the locking of the well cover are operated by a special inner triangle spanner, the utility model is not only safe, but also convenient.

Description

A kind of Safety well cover

Technical field

The utility model relates to well lid, is specially adapted to the well lid of communication cable on the road or sewage conduct maintenance usefulness.

Background technology

Usually, the various well lids that use in the urban construction, it is most of that what use is the split type well lid of cylinder iron making, this well lid is divided into two parts, i.e. the base of well lid and the lid that cooperates with base.This well lid so the phenomenon in " road black hole " often occurred, has caused very big potential safety hazard or even life accident for the trip of pedestrian and vehicle because its reasons in structure is very easy stolen.Also usually by the automobile pressure, easily cause traffic accident on the other hand.The Chinese patent literature publication number is a kind of Safety well cover of 91208225.9, and its structure shows it is to fix with bolt, rotating shaft at well lid one end, and the other end is fixed with locking bolt, rotation hammerlock.But this rotation lock arm configuration can at will rotate, and is therefore, fool proof not enough in actual use.

The utility model content

The utility model purpose is according to above-mentioned the deficiencies in the prior art part, proposes the fixing Safety well cover in a kind of two ends, and on the rotation hammerlock retaining mechanism is set, and reaches the purpose of antitheft and good stability.

The utility model purpose is realized by following technological means:

The utility model is by well lid, well seat, well lid connects by rotating shaft with the well seat, well lid is provided with locking device, the rotatable bottom that extends to the well seat of shank of the key, and the upper end of locking device is triangle or regular polygon, it is characterized in that, present hook-shapedly 14 on the side of shank of the key, a through hole is set on well lid again, in the hole, be provided with rotating shaft, the upper end of this rotating shaft is triangle or regular polygon, the bottom for shank of the key on hook-shaped 14 be complementary hook-shaped 15; On the well seat, be evenly distributed to few 4 circular holes 5.

Advantage of the present utility model and significant technique effect are, have only and rotated the latch hook rotating shaft, could rotate the shank of the key rotating shaft, guaranteed the relative safety of well lid, in addition, owing to be evenly distributed to few 4 circular holes 5 on the well seat, by bolt or reinforcing bar and concrete and well-grounded linking together, and all parts are not consumable accessorys, and therefore whole Safety well cover is sturdy and durable; Because well lid is that two ends are fixed, the good stability of well lid is difficult for going adrift or by the automobile pressure, safety is good; Because the unlatching of well lid and locking are to use special-purpose interior triangle wrench operated, both safety is convenient again.

Specific embodiments

The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician of the same trade understands:

Show as accompanying drawing 1,2,3,4,5,6,7,8, wherein label 1-16 represents hole, garden, the rotating shaft of 6-latch hook, the rotating shaft of 7-shank of the key, 8-latch hook handle, 9-latch hook rotating shaft triangular prism, 10-shank of the key, 11-shank of the key rotating shaft triangular prism, 12-shank of the key axle bracing or strutting arrangement, hole, 13-garden that 1-well lid, 2-well seat, 3-shank of the key fastening devices, 4-rotating shaft fastening devices, 5-and ground are fixing respectively; The 14-latch hook; The 15-latch hook; 16-latch hook rotating shaft bracing or strutting arrangement

Embodiment 1:

The utility model is by well lid 1, well seat 2, well lid 1 connects by rotating shaft 4 with well seat 2, well lid 1 is provided with locking device 3, locking device 3 comprises shank of the key rotating shaft 7 and shank of the key 10, shank of the key 10 is fixed on the bottom of shank of the key rotating shaft 7, the shank of the key 10 rotatable bottoms that extend to well seat 2, the upper end of shank of the key rotating shaft 7 is a triangle 11, there is a shank of the key axle bracing or strutting arrangement that is groove 12 bottom of shank of the key rotating shaft 7, its objective is rotating shaft 7 can rationally be installed, present hook-shaped 15 on the side of shank of the key 10, a through hole is set on well lid 1 again, in the hole, be provided with latch hook rotating shaft 6, the upper end of this rotating shaft 6 is a triangle 9, the bottom for shank of the key on hook-shaped 15 be complementary hook-shaped 14, the described implication that is complementary is can make latch hook 14 and 15 interlockings by rotating shaft 6 and 7, there is a latch hook rotating shaft bracing or strutting arrangement that is groove 16 bottom of latch hook rotating shaft 6, its objective is rotating shaft 6 can rationally be installed; On the well seat, be evenly distributed to few four circular holes 5, pass hole 5 and combine with concrete by bolt or reinforcing bar well seat 3 and well-grounded linking together, two rotating shafts 6,7 can only be pulled and could rotate with the special spanner of interior triangle, have guaranteed the relative safety of well lid.
