Abstract

The utility model discloses a theftproof manhole cover and a drain cover, which relate to municipal construction facilities for water supply, gas supply, sewerage, conduits, cable shafts, and water drainage. The theftproof manhole cover and the drain cover are only composed of a base and a top cover. The theftproof manhole cover and the drain cover are mainly characterized in that one side of the base is provided with two slots in a cambered surface shape, while one side of the top cover is provided with two supporting shafts in a half sphere shape. Before construction, the base and the top cover can be organically sheathed together by the slots and the supporting shafts; after construction, the base is fixed by concrete, and slot ports are closed, and the upper cover can only be opened or closed but can not be taken off easily. The utility model has the advantages of simple structure, convenient opening and closure, high theftproof performance, high safety, high durability, easy making and obvious social and economic benefits.

Description

Theftproof manhole cover and drain cover

The utility model belongs to the urban construction facility, relates to supply water, the antitheft manhole cover of usefulness such as air feed, sewage, pipeline, cable shaft and the antitheft rainwater that the ditch draining is used comb.

In recent years in the town road and near the manhole cover the building and rainwater comb often stolenly, therefore the human casualty accident that causes is also the time and take place, this not only makes national urban operating mechanism be damaged, and driving and pedestrains safety are all caused very big infringement.In order to address this problem technically, many people have designed various types of manhole covers and rainwater is combed, but the complex structure that has, the theftproof performance that has is also not really desirable, and the folding that has is also not too convenient.

The purpose of this utility model is exactly that the antitheft manhole cover and the rainwater that will provide a kind of improvement to form are combed, and it is not only simple in structure, and theftproof performance is better, and folding is also very convenient.

The total design of the utility model is achieved in that antitheft manhole cover and rainwater comb by base and loam cake composition, and base one side is provided with the groove of two arc shapes, and loam cake one side is provided with the fulcrum of two hemisphere shapes.Base and loam cake can organically be sleeved on together by groove and fulcrum before the construction, the construction rear base is fixed by concrete, and the ditch notch also is closed, and at this moment fulcrum can only make loam cake rotate folding under the constraint of groove, and can not take away easily, thereby reach antitheft purpose.

The utility model has following advantage:

1, have only base and loam cake to form from structure, thereby structure is simple especially.

2, the construction rear base is fixed, the sealing of ditch notch, and difficult ditch notch engraving tool is opened of stealer taken loam cake away, thereby theftproof performance is reliable.

3, do not have pintle hook lock, thereby folding is very convenient.

4, fulcrum is the hemisphere shape, and is cast in loam cake, thereby not fragile, is difficult for silting up, more can not become flexible, and rotate flexibly, and is durable in use.

5, base and loam cake form through casting, and without machining, thereby manufacture craft is not too complicated.

6, open the back loam cake and move down, existing side by side is placed on a side, upwards do not carry and can not cover, thereby when work is as safe as a house.

7, use the utility model, base and loam cake just must be sleeved on together at the beginning, thereby can avoid original standard well lid and rainwater to comb and the sort ofly after reaching fashionable dress lid or dress lid, do not stolen the dangerous accident that takes place again, have tangible economic benefit and social benefit.

Structure of the present utility model and shape are drawn by Figure of description: Fig. 1 is the construction cut-away view of antitheft manhole cover, and Fig. 2 is the vertical view of antitheft manhole cover; Fig. 3 is the construction cut-away view that antitheft rainwater is combed, and Fig. 4 is the vertical view that antitheft rainwater is combed, the direction when arrow is represented folding among the figure.

For the ease of implementing, structure of the present utility model, shape and principle are described in more detail below in conjunction with Figure of description.

The utility model is to improve slightly on the basis that well lid and inlet for stom water are combed in " national general water supply and drainage standard collective drawings (S147 and S235) " to form.Its structure is formed by base (1) and loam cake (2); Its principal character all is the groove (3) that is provided with two arc shapes in a side of base (1), and be provided with the fulcrum (4) of two hemisphere shapes in a side of loam cake (2), set groove (3) is what erect, and the ditch notch is downward, set fulcrum (4) is at side two ends of loam cake (2), and symmetry.In fulcrum (4) can pack groove (3) into from the ditch notch before the construction, and be sleeved on the base (1) through turning handle loam cake (2); Construction rear base (1) is fixed by concrete, and the ditch notch also is closed simultaneously, and at this moment loam cake (2) can only be pressed the direction folding of arrow indication, and can not arbitrarily take away.After loam cake (2) is opened, can stand in a side of base (1).Loam cake when covering (2) should omit upwards mentions, and rotates and can build by the arrow direction again.

Be explained as follows again in order to implement better:

1, is shaped as the basic configuration that antitheft manhole cover and rainwater are combed shown in accompanying drawing 2 and the accompanying drawing 4, if can design heavy, the light-duty series of products that vary in size with specification by the principle of eigen.

2, the pattern of antitheft manhole cover end face is not drawn, and can make with reference to domestic S147 standard, can design voluntarily by customer requirements yet.

When 3, using antitheft manhole cover in the utility model, be coated with a little antirust oil at the fulcrum place before Ying Yu will construct, and when concrete does not solidify fully folding once, in case do solid after bad uncapping, also A place concrete to be disposed when uncapping first.

Claims

1, antitheft manhole cover and rainwater are combed and are formed by base (1) and loam cake (2); Its principal character is the groove (3) that is provided with two arc shapes in a side of base (1), and a side of loam cake (2) is provided with the fulcrum (4) of two hemisphere shapes.

2, antitheft manhole cover according to claim 1 and rainwater are combed, and it is characterized in that set groove (3) erects, and notch are downward.

3, antitheft manhole cover according to claim 1 and rainwater are combed, and it is characterized in that the side two ends of set fulcrum (4) at loam cake (2), and symmetry.
