Abstract
The invention provides a rotational molding inspection shaft, belongs to the technical field of rotational molding, and solves the problems that the existing connector of the inspection shaft is soft and easy to deform, so that the connection is not firm or the sealing effect is bad. The rotational molding inspection shaft comprises a matrix with an opening at the upper end and connectors at two ends respectively, and a connecting pipe connected to the connectors, wherein the opening and the two connectors are communicated; and the connectors are double-layered structures and are provided with detachable structures that can be connected with the connecting pipe. The rotational molding inspection shaft is provided with the connectors with the double-layered structures, and has the characteristics of good rigidity, high strength, good corrosion resistance, good shock resistance and low die cost.
Description
Technical field
The invention belongs to the rotational moulding technical field, relate to a kind of rotational moulding inspection well.
Background technology
At present, the manhole on market mainly is divided into two large classes: injection moulding manhole and rotational moulding inspection well, and wherein injection moulding manhole rigidity is better, and die cost is expensive, and the rotational moulding inspection well rigidity is not good enough, die cost is cheap.Utilize the general bore of manhole dimensions of Shooting Technique production less than Φ 600, and rotational moulding inspection well can be accomplished the manhole of diameter of phi 4000.The mould of injection moulding manhole is revised difficulty, produces easily and scraps, and the rotational moulding inspection well mould is revised very convenient.
When rotational moulding inspection well is connected with pipeline, if pipe diameter changes, so whole rotational moulding inspection well 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 such as the Chinese patent announcement, comprise that the upper end has parent and two tube connectors that opening and two ends have respectively connector, 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.Can be so that the advantage that cost is low and the mould in saving workshop takes up room as long as make the tube connector mould of a parent mould and different bores when producing different manhole thereby this manhole has.But the connector of this manhole is softer, and easily distortion causes connecting insecure or sealing effectiveness is poor.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed the large rotational moulding inspection well of a kind of structural strength.
Purpose of the present invention can realize by following technical proposal: a kind of rotational moulding inspection well, 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 respectively connector, 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 is not easy distortion so that parent strength and stiffness when being connected with tube connector are better, has improved the stability of parent two connectors.
In above-mentioned rotational moulding inspection well, 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 inspection well, 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 inspection well, 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 inspection well, 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 inspection well, described parent bottom is fixed with some legs for supporting parent.Leg can make the parent can be steady when installing or place.
Compared with prior art, this rotational moulding inspection well has double-deck connector, good rigidly, and intensity is high, 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 be designed with the size of different size, thereby realizes that easily same connector diameter connects from different pipelines, has reduced die cost.

Fig. 2 is the parent internal construction schematic diagram of rotational moulding inspection well of the present invention.
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 embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1 and Figure 2, this rotational moulding inspection well 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 respectively connector, 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 to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
