Abstract

The utility model relates to a conjoined composite material well cover, mainly comprising a composite material well cover and a composite material frame, two corresponding inner sides at one end of the composite material frame are provided with a rotating pin respectively, two corresponding sides at one end of the composite material well cover are provided with a pin hole respectively, four sides in the composite material frame are provided with a bearing support respectively, the pin hole is a bar-shaped groove along the composite material well cover side direction, the composite material well cover is supported on the bearing support of the composite material frame in the way that the bar-shaped groove is matched with the rotating pin, and the length of the bar-shaped groove is more than or equal to the thickness of the composite material well cover. According to the utility model, by employing the relative movement of the bar-shaped groove at the side of the well cover and the rotating pin in the frame, the well cover can be quickly opened on a ring of bearing support at the inner side of the frame, after the well cover is closed, the pressure can be extorted on the ring of bearing support at the inner side of the frame below the well cover completely, moreover, the conjoined composite material well cover has simple structure convenient production and manufacture, stable structure, good pavement bearing performance, high safety and long service life.

Description

The disjunctor composite drain cover

Technical field

The utility model relates to a kind of well lid, is a kind of disjunctor composite drain cover specifically.

Background technology

The well lid that tradition is used for the road inlet of sewer is an absolute construction, and well lid is stolen by the people easily, thereby influences the current of road.Existing Contiuum type well lid adopts well lid to connect pre-buried framework, and pre-buried framework and road construction are integral, well lid can be on framework Unscrew or close to satisfy maintenance, to clear up requirements such as sewer, well lid can't be stolen by the people, has ensured road safety.

The patent No. is the disclosed a kind of thief-proof rain grid made that lifts of CN87201534, adopt metal shaft that cast iron double-edged fine-toothed comb and concrete frame are connected together, both having prevented effectively that cast iron grate on the grate water device is removed steals, the cast iron grate upwards can be started the carrying out that does not influence desilting scrubbing work again, its weak point is: the concrete frame inboard is provided with the seat ring of placing cast iron grate pressure-bearing, the seat ring of metal shaft one side concrete frame inboard must hollow out so that the cast iron grate rotates around metal shaft and not cause interference, the seat ring of metal shaft opposite side concrete frame inboard is a bearing surface, the no bearing surface in cast iron grate below of no seat ring one side, as vehicle when no seat ring one side crosses, easily cause the upset of cast iron grate, or the metal bearing compressive strain damages the initiation security incident.

Summary of the invention

In order to solve the deficiencies in the prior art, the purpose of this utility model provide a kind of simple in structure, easily manufactured, open and close rapidly, load-carrying properties are good, not fragile, security performance is high disjunctor composite drain cover.

In order to achieve the above object, the technical solution adopted in the utility model is: the disjunctor composite drain cover, mainly comprise composite drain cover and composite material frame, be equipped with rotating dog on corresponding two inner side edges of composite material frame one end, on the corresponding dual-side of composite drain cover one end pin-and-hole is arranged all, its technical characterictic is that the inboard four side of described composite material frame is equipped with supporting base, described pin-and-hole is a bar-shaped trough along the composite drain cover side directions, composite drain cover cooperates rotating dog to be supported on the composite material frame supporting base through bar-shaped trough, and the length of described bar-shaped trough is more than or equal to the thickness of composite drain cover.When composite drain cover was opened, well lid rotated around axis of rotation, and the relative rotating dog of the bar-shaped trough of well lid side slides and makes well lid be rotated down supporting base and the relative framework of well lid that end pushes against the framework inboard to move up simultaneously, and well lid can normally be opened; When composite drain cover was closed, well lid rotated around axis of rotation, and the relative rotating dog slip of the bar-shaped trough of well lid side simultaneously makes well lid be rotated down the relative framework of end and moves down, and well lid is closed the complete pressure-bearing of back well lid on the inboard circle supporting base of framework.The well lid conveniently opening and closing, load-carrying properties are good, and rotating dog is difficult for deformed damaged, long service life.

The utility model adopts well lid side bar-shaped trough to cooperate the rotating dog of framework inboard to relatively move, well lid can be opened rapidly on the inboard circle supporting base of framework, and the complete pressure-bearing of the inboard circle supporting base of square bearer under the well lid after the well lid closure, it is simple in structure, it is convenient to manufacture, Stability Analysis of Structures, and the road surface load-carrying properties are good, the security performance height, long service life.

Description of drawings

Fig. 1 is the utility model closing structure schematic diagram;

Fig. 2 is the utility model Unclosing structure schematic diagram;

Fig. 3 is the perspective view of Fig. 2.

Among the figure: composite drain cover 1, composite material frame 2, rotating dog 3, supporting base 4, bar-shaped trough 5.

The specific embodiment

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

Disjunctor composite drain cover shown in Fig. 1,2,3, mainly comprise composite drain cover 1 and composite material frame 2, composite material frame 2 inboards are provided with a circle supporting base 4, be equipped with rotating dog 3 on corresponding two inner side edges of composite material frame 2 one ends, on the corresponding dual-side of composite drain cover 1 one ends pin-and-hole is arranged all, pin-and-hole is a bar-shaped trough along the composite drain cover side directions, the length of bar-shaped trough is more than or equal to the thickness of composite drain cover, and composite drain cover cooperates rotating dog to be connected on the composite material frame through bar-shaped trough.Well lid is around axis of rotation Unscrew or closure, and the relative rotating dog slip of the bar-shaped trough of well lid side simultaneously is rotated down well lid and holds the supporting base and the relative framework of well lid that push against the framework inboard to move up or down, realize opening or closure of well lid.
