Abstract

The utility model relates to a theft-proof rain-drainage well cover which belongs to an accessory for urban section engineering. A hole is respectively arranged on two frame edges opposite to a frame seat of an ordinary rain-drainage well cover. A shaft which is matched with the hole is respectively arranged on the corresponding positions of two opposite edges on the well cover and is provided with an installing notch. After installed, the installing notches are sealed by construct material, and the well cover can only circle the two shafts to rotate. The theft-proof rain-drainage well cover is only composed of a frame seat and the well cover. The theft-proof rain-drainage well cover is not additionally provided with attachments. Finished products are made once. Thus, the utility model has the advantages of material saving, no secondary operation, labor saving, low cost, high safety, high theft-proof performance and easy installation and use; the theft-proof rain-drainage well cover is not easy to break.

Description

Theft-proof rain-drainage well cover

A kind of Theft-proof rain-drainage well cover belongs to the municipal engineering ancillary facility.

In the modern city, at road, ground such as square all are provided with the discharge pipe line that discharges ponding such as rainwater, be cleaning, safeguard discharge pipe line, certain distance at discharge pipe line, all be provided with cleaning on the ground, the wellhole of maintenance pipeline communicates with pipeline, on wellhole, be provided with the well lid of protection, usually well lid is made of skeleton frame and well lid, and skeleton frame separates with well lid, after well lid was moved apart skeleton frame, well head just exposed on ground like this, and driving or personal injury very easily take place, especially a nearly period, a few peoples steal well lid unexpectedly without restraint, and a large amount of well lids is stolen, not only badly damaged city urban operating mechanism, country is sustained a loss, and children or pedestrian mistake takes place frequently subside tragedy in well.For preventing the generation of this phenomenon, the someone designs, makes and use the Theft-proof rain-drainage well cover of various structures.This class Theft-proof rain-drainage well cover mainly contains three kinds of structures: a kind of is welding the preceding paragraph iron chains between former skeleton frame and well lid, with the iron chains of certain-length well lid is connected on the skeleton frame; Another kind of structure is on well lid and the contacted one side of skeleton frame, the welding upper hinge; Another structure is contacted one jiao of well lid and skeleton frame, establishes a fixed axis and hole.The Theft-proof rain-drainage well cover of these three kinds of structures all increases an annex, strengthens material consumption, all wants secondary operations, waste of manpower, and increase use cost, and the iron chains, hinge, the axis hole that increase, also easily destroyed, safety is not high, and theftproof performance is not high, installs, uses inconvenient.

The purpose of this utility model is: designs a kind of have only well lid and skeleton frame, do not increase material consumption, and the time processing moulding, use cost is low, safety good, theftproof performance is high, installation, anti-stolen water rain well lid easy to use.

The purpose of this utility model is achieved in that on two relative edges of skeleton frame (1) one side, respectively establish the hole (2a) of a coaxial line, (2b), on the relative both sides of well lid (4) one sides, respectively establish one with skeleton frame (1) on hole (2a), the axle that (2b) adapts (6a), (6b), and axle (6a) length should be greater than axle (6b), after axle (6a) penetrates hole (2a), again axle (6b) is penetrated in the hole (2b), like this after being sealed around the skeleton frame, well lid (4) is because of axle (6a), (6b) can not move axially and can't separate with skeleton frame, but can be around axle (6a), (6b) rotate and open or cover.

This Theft-proof rain-drainage well cover only is made of skeleton frame and well lid, and does not increase any annex, so economical with materials, the finished product of producing once out does not need secondary operations, the few manpower of joint, thereby use cost is low, and be difficult for destroyedly, safe, theftproof performance is good, is easy to simultaneously install, use.

Describe the structure of this Theft-proof rain-drainage well cover in detail below in conjunction with accompanying drawing.

Fig. 2 is the A-A sectional view of crib among Fig. 1 (1)

Fig. 3 is the B-B sectional view of crib among Fig. 1 (1)

Fig. 4 is the structural representation of well lid (4)

Fig. 5 is that the D of Fig. 4 is to view

Fig. 6 is the C-C sectional view of Fig. 4

The structure of this Theft-proof rain-drainage well cover as shown in Figure 1, consisted of by skeleton frame (1) and well lid (4), the structure of skeleton frame (1) such as Fig. 2, shown in Figure 3, three edge inboards in four edges are provided with convex (3), and on relative in addition two edges of edge one side that does not have convex, respectively establish hole (2a), (2b) of a coaxial line. The structure of well lid (4) such as Fig. 4, Fig. 5, shown in Figure 6, the same with general well lid, on well lid (4), be provided with a plurality of osculums (5), on two limits corresponding with hole (2a), (2b) of skeleton frame (1), be provided with axle (6a), (6b) of coaxial line, and axle (6a) length is greater than (6b), in order to penetrate in the hole (2a), respectively make an installation gap at axle (6a), (6b) two places of well lid (4) to axle (6a) (7a), (7b), so just can at first extend into axle (6a) in the hole (2a), afterwards when mobile well lid (4) round about, axle (6b) is extend in the hole (2b), well lid (4) is put into skeleton frame (1), well lid (4) is supported in skeleton frame (1) on the convex (3) of edge inboard in the skeleton frame (1), crib seat four limits after the installation, shut by construction material after the construction, like this, axle (6a), (6b) can not produce and move axially, and well lid (4) relies on the axle (6a) of coaxial line, (6b) can only upwards rotate, and can separatedly not hold, therefore can prevent reliably that well lid is stolen.

Execute example:

1, the skeleton frame of well (1) is made of casting method, does not have in the inboard on relative two edges in addition of the side of edge of convex (3), and the hole (2a) that is shaped on coaxial line (2b).

2, well lid (4) adopts casting method to make equally, remove and make well lid (4) and skeleton frame (1) can match and leave drain hole (5), also have three features in addition, the one, make axle (6a) length greater than (6b), the 2nd, at axle (6a), (6b) two places respectively establish an installation gap (7a), (7b), and at diaxon (6a), on the axial direction (6b), breach (7a) length is greater than the length of breach (7b), so that well lid (4) is during perpendicular to skeleton frame (1), can penetrate into axle (6a) in the hole (2a) fully, afterwards again can be well lid (4) when mobile round about, axle (6b) is penetrated in the hole (2b), axle (6a), length (6b) should guarantee well lid (4) when normal operation position, can be from the hole (2a), come off (2b); The 3rd, axle (6a), (6b) are positioned at the soffit of well lid (4), and be provided with the position of axle (6a), (6b) side upper surface at well lid (4), make arcwall face (8), to guarantee that well lid (4) is around axle (6a), (6b) when upwards rotating, the angle of rotating is keeped in repair, is cleared up to guarantee safety at the 100-120 degree.
