Abstract
The utility model provides a rotational molding inspection well, belongs to the technical field of rotational molding and solves problems that connection ports of the existing inspection well are soft and easy to deform and accordingly infirm connection or the bad sealing effect is caused. The rotational molding inspection well comprises a main body and a connection pipe, wherein the upper end of the main body is provided with an opening, two ends of the main body are provided with connection ports respectively, the connection pipe can be connected with the connection ports, the opening is communicated with the two connection ports in double-layer structures, and each connection port is provided with a detachable structure connected with the connection pipe. The rotational molding inspection well is provided with the connection ports in the double-layer structures and is good in rigidity, corrosion resistance and shock resistance, high in strength and low in mold cost.
Description
Technical field
The utility model belongs to the rotational moulding technical field, relates to a kind of rotational moulding manhole.
Background technology
At present, the manhole on market mainly is divided into two big classes: injection moulding manhole and rotational moulding manhole, and wherein injection moulding manhole rigidity is better, the die cost costliness, and rotational moulding manhole rigidity is not good enough, die cost is cheap.Utilize the general bore of manhole dimensions of Shooting Technique production less than Ф 600, and the rotational moulding manhole can be accomplished the manhole of diameter Ф 4000.The mould of injection moulding manhole is revised difficulty, is easy to generate and scraps, and rotational moulding manhole mould is revised very convenient.
When the rotational moulding manhole is connected with pipeline, if pipe diameter changes, so whole rotational moulding manhole will be made again, and the redesign mould has caused the raising of cost of production like this.For this reason, people have designed dismountable manhole, a kind of manhole as the Chinese patent announcement, comprise that the upper end has parent and two tube connectors that opening and two ends have connector respectively, opening and two connectors are interconnected, and the inner mouth of pipe of two tube connectors can be connected with two connector removable seals respectively.Thereby this manhole has when producing different manhole as long as make the advantage that the tube connector mould of a parent mould and different bores can make that cost mould low and the saving workshop takes up room.But the connector of this manhole is softer, and easy deformation causes connecting insecure or sealing effectiveness is poor.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the big rotational moulding manhole of a kind of structural strength.
The purpose of this utility model can realize by following technical proposal: a kind of rotational moulding manhole, comprise that the upper end has parent and the tube connector that can link to each other with connector that opening and two ends have connector respectively, described opening is connected with two connectors, it is characterized in that described connector is double-decker and has the demountable structure that is connected with tube connector.
Double-deck connector makes that parent strength and stiffness when being connected with tube connector are better, is not easy distortion, has improved the stability of parent two connectors.
In above-mentioned rotational moulding manhole, described demountable structure comprises the convex body of connector external surface and the groove of tube connector inboard, and described projection can embed parent is linked to each other with tube connector.
In above-mentioned rotational moulding manhole, described demountable structure comprises the external screw thread that the connector external surface is offered, and is provided with the internal thread that is complementary with external screw thread in the described tube connector internal diameter.Tube connector can be enclosed within to be realized on the bellmouth closely cooperating, and is not easy to come off, and realizes removably connecting.
In above-mentioned rotational moulding manhole, described opening part axially is evenly equipped with the reinforcing rib one of annular.Reinforcing rib one structure has improved intensity and the rigidity of parent opening part.
In above-mentioned rotational moulding manhole, axially be evenly equipped with reinforcing rib two between two described connectors.Reinforcing rib two structures have improved intensity and the rigidity at parent two connector places.
In above-mentioned rotational moulding manhole, described parent bottom is fixed with some for the leg that supports parent.Leg can make the parent can be steady when installing or place.
Compared with prior art, this rotational moulding manhole has double-deck connector, good rigidly, and the intensity height, good corrosion resistance, shock resistance is good, and die cost is low; And only needing a manhole parent of processing and fabricating mould, tube connector can design the size of different size, thereby realizes that easily same connector diameter connects with different pipelines, has reduced die cost.
Description of drawings
Fig. 1 is the external structure schematic diagram of rotational moulding manhole described in the utility model.
Fig. 2 is the parent internal construction schematic diagram of rotational moulding manhole described in the utility model.
Among the figure, 1, parent; 2, opening; 3, connector; 4, reinforcing rib one, 5, reinforcing rib two; 6, tube connector; 7, double-decker.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1 and Figure 2, this rotational moulding manhole comprises that the upper end has parent and the tube connector that can link to each other with connector that opening and two ends have connector respectively, opening is connected with two connectors, and connector is double-decker 7 and has the demountable structure that is connected with tube connector.
Specifically, demountable structure comprises the external screw thread that the bellmouth external surface is offered, and is provided with the internal thread that is complementary with external screw thread in the tube connector internal diameter.Opening part axially is evenly equipped with between annular one, two connector of reinforcing rib and axially is evenly equipped with reinforcing rib two.The parent bottom is fixed with two legs that are used for supporting parent.
During production, produce parent as long as make a parent mould, because precursor structure can be general, according to reality of work, make the be complementary tube connector of size of different and pipe diameter, so both reduced the mfg. moulding die cost, also avoided mould too much to take the space, workshop.
In use, when running into the pipeline of different bores, as long as can satisfy the connection requirement of each pipeline at the tube connector of the corresponding caliber size of parent installation.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
