Description

Five preventing well covers

Technical field

The utility model is related to urban operating mechanism field, specially a kind of anti-settling, leap preventing, noise control, antitheft, fall arrest Five preventing well covers.

Background technology

Because the manhole cover loss on road and caused by personal injury event and power communications facility it is stolen produced by wealth Production loss occurs often.When well lid is lost, easily cause the generation for the security incident that personnel fall.Well lid mounting structure does not conform to Reason, makes well lid be easy to and displacement.Traditional well lid is also easy to when locomotive is rolled the escape from cover seat of manhole, works as well lid It when popping out cover seat of manhole, can fly the whole vehicle body bullet of moving traffic, or fall into well head, What is more can then collide To sailing below or head-on on next vehicle, the tragedy of several car chain collisions is caused.When locomotive rolls well lid, well lid and walling crib rigidity Collision produces noise greatly, greatly affected resident's living environment on both sides of the road.

Utility model content

The purpose of this utility model is to provide a kind of five preventing well cover, it is ensured that well lid possesses anti-settling, leap preventing, noise control, anti- Robber, the characteristic of fall arrest.

To achieve these goals, the scheme that the utility model is used for：A kind of five preventing well covers, including well lid, the well Lid is hinged with walling crib by jointed shaft, is offered on the well lid and trapezoidal shock absorption bar, the well are fixed with sled mouth, the walling crib Base face and trapezoidal shock absorption bar against；The well being covered on well head is provided with the walling crib to comb；It is provided with the well lid anti- Steal lock；It is fixed with the well lid bottom surface on U-shaped dop, the inner peripheral surface of the walling crib and offers neck, the neck and U-shaped card Head coordinates to fix well lid.

Compared with prior art, technique effect of the present utility model is：By being provided with theftproof lock, such well on well lid Lid just possesses antitheft function；U-shaped dop is fixed with well lid bottom surface, is offered on the inner peripheral surface of walling crib and U-shaped card Corresponding neck, neck coordinates to fix well lid with U-shaped dop, effectively can prevent well lid from jumping；It is solid in the walling crib Surely there is trapezoidal shock absorption bar, the well lid bottom surface is with trapezoidal shock absorption bar against such well lid is contacted with walling crib to be non-rigid, not only greatly The generation of noise is reduced greatly, and further can prevent well lid from jumping；It is provided with and is covered on well head in the walling crib Well is combed, even if so well lid is lost, can also prevent personnel from falling to well, it is ensured that the life security of personnel.Possess well lid excellent Different anti-settling, leap preventing, noise control, antitheft, fall arrest characteristic.

Brief description of the drawings

Fig. 1 is the overall dimensional structure diagram of the utility model.

Embodiment

The utility model is described in further detail with reference to Fig. 1.

A kind of five preventing well covers, including well lid 10, the well lid 10 is hinged with walling crib 20 by jointed shaft, on the well lid 10 Offer sled mouth 13, be fixed with trapezoidal shock absorption bar 21 in the walling crib 20, the bottom surface of well lid 10 and trapezoidal shock absorption bar 21 against； The well comb 22 being covered on well head is provided with the walling crib 20；Theftproof lock 11 is provided with the well lid 10；The well lid 10 It is fixed with bottom surface on U-shaped dop 12, the inner peripheral surface of the walling crib 20 and offers neck 24, the neck 24 and U-shaped dop 12 Coordinate to fix well lid 10.

In such scheme, when the effect of applying power is constant on well lid 10, increase walling crib 20 and the contact area on ground, this Sample just reduces size of the walling crib 20 to ground pressure, considerably increases the effect of the anti-settling of well lid 10；By on well lid 10 Theftproof lock 11 is provided with, such well lid 10 just possesses antitheft function；U-shaped dop 12 is fixed with the bottom surface of well lid 10, The neck 24 corresponding with U-shaped dop 12 is offered on the inner peripheral surface of walling crib 20, neck 24 coordinates to fix well with U-shaped dop 12 Lid 10, automobile can effectively prevent well lid 10 from jumping when rolling well lid 10；Trapezoidal shock absorption bar is fixed with the walling crib 20 21, the bottom surface of well lid 10 is with trapezoidal shock absorption bar 21 against such well lid 10 is contacted with walling crib 20 to be non-rigid, is not only dropped significantly The low generation of noise, and can further prevent well lid 10 from jumping；It is provided with and is covered on well head in the walling crib 20 Well comb 22, even if so well lid 10 is lost, can also prevent personnel from falling to well, it is ensured that the life security of personnel.Make well lid 10 Possess excellent anti-settling, leap preventing, noise control, antitheft, fall arrest characteristic.

As well 22 specific mounting structures of comb, the well combs 22 entirety in netted, solid on the inner peripheral surface of the walling crib 20 Surely there are at least two chutes 23, the chute 23 includes flute length direction and first and second axially in parallel groove, first and second groove Between connected by flute length direction with axially vertical short groove, the well is combed and is fixed with slide-bar 221, first groove on 22 side faces Notch slip into upwards for slide-bar 221.

When well combs 22 installation, by the slide-bar 221 of well comb 22 after the notch of the first groove is slipped into, slide-bar 221 and short groove Cell wall is against then rotating well and comb 22 so that slide-bar 221 is fallen into the second groove.Well comb 22 is quick and easy for installation.

Preferably, three chutes 23 are fixed with the inner peripheral surface of the walling crib 20.The inner peripheral surface of walling crib 20 is general Three chutes 23 are provided with, to ensure that well comb 22 is reliably seated to precalculated position.
