Abstract
The invention discloses a compound rectangular expansion joint. The compound rectangular expansion joint comprises a cylindrical rectangular outer frame, a fixed screw rod is arranged in the internal space of the outer frame in the radial direction, the outer wall of the fixed screw rod is connected with an inner frame through a plurality of reinforcing ribs, the inner frame and the outer frame are parallel to each other, a plurality of inner cavities in the radial direction are formed between the inner frame and the fixed screw rod, the inner frame is connected with the outer frame through a plurality of reinforcing ribs, a plurality of outer cavities in the radial direction are formed between the inner frame and the outer frame, four reinforcing ribs are arranged between the fixed screw rod and the inner frame, and eight reinforcing ribs are arranged between the inner frame and the outer frame. The compound rectangular expansion joint disclosed by the invention is formed by connecting the outer frame, the inner frame and the fixed screw rod through the reinforcing ribs, while in use, the compound rectangular expansion joint is connected with a pipeline at the internal part through the fixed screw rod, and the inner cavities inside the expansion joint have the functions of conduction drainage; as the whole expansion joint is of a three-dimensional frame structure, the compound rectangular expansion joint is high in mechanical strength, difficult to deform and damage in the use process and long in service life.
Description
Technical field
The present invention relates to a kind of expansion joint, more precisely, be a kind of compound rectangular expansion joint.
Background technology
Expansion joint is the additional stress caused because of temperature difference and mechanical vibration for compensation, and a kind of flexible structure being arranged on container casing or pipeline.Owing to it is as a kind of elastic compensation element that can freely stretch, there is the advantage such as reliable operation, functional, compact conformation, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.
But, some rectangular expansion joint are not high enough owing to being restricted its mechanical strength by structure, be easily deformed, thus have impact on the service life of rectangular expansion joint in using.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of compound rectangular expansion joint with higher mechanical strength.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of compound rectangular expansion joint, comprise a tubular rectangular outer frame, the inner space of described housing is radially provided with a standing screw, the outer wall of described standing screw is connected with inside casing by some reinforcements, described inside casing is parallel to each other with housing, forming some inner chambers radially between inside casing and standing screw, inside casing is connected with housing by some reinforcements, forms some exocoels radially between inside casing and housing.
As preferred embodiment of the present invention, the reinforcement between described standing screw and inside casing is 4.
As preferred embodiment of the present invention, the reinforcement between described inside casing and housing is 8.
The compound rectangular expansion joint of the present invention is formed by connecting by reinforcement by housing, inside casing and standing screw, it is connected with pipeline in inside by standing screw when of use, expansion joint internal cavity plays the effect of conduction drain, owing to whole expansion joint is space frame structure, mechanical strength is higher, being unlikely to deform damage during use, service life is longer.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the compound rectangular expansion joint of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention are made apparent clear and definite defining.
As shown in Figure 1, a kind of compound rectangular expansion joint 1, comprise a tubular rectangular outer frame 2, the inner space of described housing 2 is radially provided with a standing screw 3, the outer wall of described standing screw 3 is connected with inside casing 4 by some reinforcements, and described inside casing 4 is parallel to each other with housing 2, forms some inner chambers 5 radially between inside casing 4 and standing screw 3, inside casing 4 is connected with housing 2 by some reinforcements, forms some exocoels 6 radially between inside casing 4 and housing 2.
As to further improvement of the present invention, the reinforcement between described standing screw 3 and inside casing 4 is 4.
As to further improvement of the present invention, the reinforcement between described inside casing 4 and housing 2 is 8.
The compound rectangular expansion joint of this invention is formed by connecting by reinforcement by housing, inside casing and standing screw, it is connected with pipeline in inside by standing screw when of use, expansion joint internal cavity plays the effect of conduction drain, owing to whole expansion joint is space frame structure, mechanical strength is higher, being unlikely to deform damage during use, service life is longer.
The mentality of designing of the present invention is below described the most in one embodiment, and in the case of system allows, the present invention can expand to the most external more functional module, thus extends its function to greatest extent.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any change expected without creative work or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
