Functional well lid

Technical field

The utility model relates to a kind of well lid that is applied to sewer, manhole etc. in the urban construction, especially a kind of functional well lid.

Background technology

Well lid (inspection shaft lid) is widely used in places such as the maintenance of sewer, bilge well, communication pipe network in the urban construction and inspection eye, plays a very important role for making things convenient for the vehicle and the masses to pass through, beautify the road environment tool.Well lid of the prior art, its material is mainly the ironcasting of metal species or steel concrete spare etc., and ironcasting gets rusty easily and to influence road attractive in appearance, and theftproof is poor simultaneously, easily stolen and influence vehicles or pedestrians current, in addition the generation vehicle sinkage, topple, the pedestrian drops to the security incident of going in the well; And steel concrete spare is fragile, anti-impact force difference etc.; In addition, ironcasting or steel concrete spare seldom are provided with vibration absorber and prevent the tumbler of loam cake with respect to base between loam cake and base, so when automobile crossed on the well lid, vibrations were big, noise is big, loam cake is easy to rotation etc.; At last, the wearing no resistance of ironcasting or steel concrete spare surface, because of wearing and tearing need often to change, application life is not long in the use.

Summary of the invention

The utility model is at the above-mentioned deficiency of well lid in the prior art, and the functional well lid of a kind of simple in structure, damping, noiseproof, anti-rotation, macromolecular material is provided.

The technical solution of the utility model: a kind of functional well lid, comprise base, cover loam cake on the base, on cover and be provided with open hole, its improvements are: be provided with one or more locating convex block on described base, on described base and step surface that described loam cake engages, be provided with sealed groove, in sealed groove, be provided with sealing ring; On the bottom surface of described loam cake, be provided with one or more detents, the locating convex block on detent and the described base corresponding, locating convex block can stretch in the detent;

On the bottom surface of described loam cake, below open hole, be provided with the waterproof sealing cover;

The upper surface of described loam cake is the diamond dust wearing layer.

Functional well lid of the present utility model adopts the compression molding of macromolecule resin material material, good toughness, antirust attractive in appearance, simple in structure; Scurry on water-tight, the anti-odour; Reduce vibrations, reduce noise; Prevent that loam cake from rotating, guaranteeing vehicle, pedestrains safety; Supporting capacity is strong, long service life; The surface is a wearing layer, guarantees that long-term use is not worn; Fundamentally solved the problem that the well lid that troubles people is stolen, supporting capacity is poor, application life is short.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model base (part 1) structural representation.

Fig. 2 is the utility model loam cake (part 2) structural representation.

Fig. 3 be Fig. 1 along A-A to sectional view.

Fig. 4 be Fig. 2 along B-B to sectional view.

The specific embodiment

In Fig. 1,2,3,4,1-base, 2-loam cake, 3-locating convex block, 4-sealed groove, 5-sealing ring, 6-open hole, 7-waterproof sealing cover, 8-detent.

In figure, functional well lid of the present utility model, the loam cake of installing 2 that matches by base 1 with base 1 is formed.The material of base 1 and loam cake 2 all is nonmetallic macromolecule resin material, and resistance to compression, tensile strength be higher, can satisfy the demand, and the shape of base 1 and loam cake 2 serves as maximum with garden shape; Loam cake 2 can cover on the opening of base 1, plays the effect of the opening of sealing base 1.Be provided with one or more locating convex block 3 on base 1, locating convex block 3 specifically is located on base 1 and the step surface that loam cake 2 engages; If more than one locating convex block 3,, then evenly distribute along this garden shape step surface as 2,3 or 4 etc.Base 1 is provided with ring packing groove 4, is provided with sealing ring 5 in sealing groove 4; Sealed groove 4 is located on base 1 and the step surface that loam cake 2 engages, ringwise sealed groove 4 is complete circles, its inner seal ring 5 after setting completed, this step surface height of its aspect ratio, after loam cake 2 covers on the base 1, the bottom surface of loam cake 2 is pressed on the sealing ring 5, just can play the effect of scurrying on sealing, waterproof, the anti-odour and reducing vibrations, reduction noise.

For convenience, mobile loam cake 2 reliably, on loam cake 2, all be provided with open hole 6 usually, be generally two; Need with loam cake 2 when base 1 is removed, general or special-purpose Move tool be inserted in the open hole 6, just can play the effect of removing.On the bottom surface of loam cake 2 with open hole 6 corresponding positions, below open hole 6, be provided with waterproof sealing cover 7, waterproof sealing cover 7 be arranged on open hole 6 below, link together securely with modes such as bonding or screw connection and loam cake 2, prevent that rainwater, sewage etc. from passing through from open hole 6, play airtight effect, can prevent that especially outside water from entering in the well from open hole 6.On the bottom surface of loam cake 2, with the locating convex block 3 corresponding positions on the base 1, be provided with one or more detents 8 and locating convex block 3 corresponding, cooperatively interact; After loam cake 2 covered on the base 1, the locating convex block 3 on the base 1 can stretch into respectively in the detent 8 on loam cake 2 bottom surfaces, prevents that loam cake 2 from rotating relative to base 1.The quantity of locating convex block 3 is one, and then the quantity of detent 8 is identical with the quantity of locating convex block 3 when above, and the position is corresponding one by one.

The upper surface of loam cake 2 of the present utility model, be in for a long time the people trample or the rolling of automobile in, so require it to have higher abrasion resistance, can resist the long-term wearing and tearing of using.The material of loam cake 2 of the present utility model is macromolecule resin (unsaturated polyester resins), and itself just has certain abrasion resistance.In order to reach more high-wearing feature, in the manufacturing process that adopts prior art, add high-abrasive material, make the wearing layer that forms one deck densification on the upper surface of loam cake 2.Particularly, be in the raw material of making loam cake 2 upper surface layers, to add diamond dust inserts (diamond dust of fine particle state), diamond dust has very high abrasion resistance for making the primary raw material of grinding class grinding wheel.The diamond dust surface course lumps together with the bottom that is in molten condition (fluid state), after being integrated, solidifying, the hydraulic press pressurization just becomes loam cake 2 with diamond dust wearing coat, the upper surface of loam cake 2 forms the diamond dust wearing layer of one deck densification, this making processing method is a prior art, no longer is described further at this.

In addition, still can adopt anti-theft device between base 1 of the present utility model, the loam cake 2, as using special-purpose anti-theft screw etc.; In fact, material of the present utility model is a disposable material, can not reclaim, so can be not stolen; The purpose that adopts anti-theft device is to prevent that cable etc. in the hoistway from implementing the generation of situation such as destroyed, stolen.The utility model adopts anti-theft device of the prior art, and not as protection domain of the present utility model, no longer is described further at this.
