Description

A kind of road manhole

Technical field

This utility model relates to municipal facilities, refers specifically to a kind of road manhole.

Background technology

Generally, the various well lids used in urban construction, major part uses the split type well lid cylinder iron made, This well lid is divided into two parts, i.e. well lid base and with the lid of base engagement.This well lid holds due to its reasons in structure very much The most stolen, therefore often occur in that the phenomenon in " road black hole ", cause the biggest potential safety hazard to the trip of pedestrian and vehicle； On the other hand the most usually by automobile pressure, vehicle accident is easily caused.

Chinese patent literature publication number is a kind of Safety well cover of 91208225.9, and its structure is to use in well lid one end Bolt, rotating shaft are fixed, and other end locking bolt, rotation hammerlock are fixed.But this rotation lock arm configuration can at will rotate, therefore, The safest.

Chinese patent literature publication number is a kind of Safety well cover of ZL200520043314.6, and this utility model is by well Lid, well seat, well lid is coupled by rotating shaft with well seat, the side of shank of the key presents hook-shaped, arranges a through hole on well lid again, Being provided with rotating shaft in hole, the upper end of this rotating shaft is triangle or regular polygon, and bottom matches for hook-shaped with on shank of the key Hook-shaped；Being uniformly distributed at least 4 circular holes on well seat, this utility model has certain advantage and technique effect, but constructs Comparatively laborious, easily vibrate through well lid, well lid at running car, be simultaneously fabricated into this higher.

Utility model content

This utility model purpose be according to the deficiencies in the prior art in place of, it is provided that a kind of road manhole, this road manhole It is to use three-point mount, good stability, is difficult to go adrift or good by automobile pressure, safety；And there is no movable part, letter Single reliable, easy to use, sturdy and durable.

This utility model purpose is realized by techniques below scheme:

A kind of road manhole, including well seat, well lid, described well seat is circular, including outer ring step and inner ring step, institute Stating to be uniformly provided with on inner ring step and extend three prominent handles to horizontal direction, the height of described outer ring step is higher than inner ring step；Institute Stating well lid lower surface and be provided with three L-type grooves, described L-type groove is the groove of unidirectional opening, opening direction level, and each recessed The circumferencial direction of channel opening is provided with a slideway, is provided with one section of transition, described transition when described slideway is close to groove The most gradually step-down, when transition is close to slot opening, the highly gradient of slideway is zero；Described well lid can pass through with well seat Three prominent handles and three L-type grooves are connected.

And, the side of described L-type groove is provided with ribs.

And, described well lid upper surface indicates the arrow of direction of rotation.

And, described well lid upper surface indicates primary importance scale, and the upper surface of described outer ring step indicates second Put scale.

And, described well lid upper surface is provided with 2-3 the circular hole not penetrated through.

And, also have 1 rotation matched with the circular hole not penetrated through to start instrument when needing to open well lid.

Advantage of the present utility model and significantly having the technical effect that

1, this utility model novel structure, simple and reliable, easy to use, do not have movable part, well lid is sturdy and durable.

2, upper well lid described in the utility model can be connected by three prominent handles and three L-type grooves with well seat；I.e. adopt With three-point mount, the good stability of well lid, it is difficult to go adrift or by automobile pressure, safety is good.

3, the circumferencial direction of each slot opening of this utility model is provided with a slideway, sets when described slideway is close to groove There are one section of transition, the height gradually step-down of described transition, the highly gradient of slideway when transition is close to slot opening It is zero；The design of this structure facilitates the precession of well lid and back-out, time saving and energy saving.

4, it is provided with ribs between L-type groove described in the utility model and transition；The design of this structure improves road The intensity of well lid, extend service life of road manhole, use safe and reliable, firm.

5, this utility model due to the unlatching of well lid and locking be to start tool operation, both safety with special rotating, Facilitate again.

Fig. 1 is this utility model well lid upward view.

Fig. 2 is Fig. 1 front view (not shown in ribs figure).

Fig. 3 is this utility model well seat top view.

Fig. 4 is Fig. 3 front view.

Wherein: well lid 1, well seat 2, L-type groove 3, prominent handle 4, slideway 5, the arrow 6 of direction of rotation, primary importance scale 7, The circular hole 8 that do not penetrates through, transition 9, outer ring step 10, inner ring step 11, ribs 12, second position scale 13.

Detailed description of the invention

Below by specific embodiment, the utility model is described in further detail, and following example are illustrative, no It is determinate, it is impossible to limit protection domain of the present utility model with this.

Structure, annexation and the method not described in detail in this utility model, all can be understood as the public affairs in this area Know general knowledge.

A kind of road manhole, as shown in Figure 1, Figure 2, Figure 3, Figure 4, including well seat 2, well lid 1, well lid 1, well seat 2 are by casting Iron material is made, and described well seat 2 is in circular, including outer ring step 10 and inner ring step 11, on described inner ring step 11 uniformly Being provided with and extend three prominent handles 4 to horizontal direction, the height of described outer ring step 10 is higher than inner ring step 11；

Described well lid 1 lower surface is provided with three L-type grooves 3, and described L-type groove 3 is the groove of unidirectional opening, opening direction Level, and the circumferencial direction of each L-type slot opening is provided with a slideway 5, is provided with one when described slideway 5 is close to L-type groove Section transition 9, the height gradually step-down of described transition 9, when transition 9 is close to L-type slot opening, the height of slideway 9 is gradually Vanishing；
