Abstract
The invention discloses a special flange. The special flange comprises a first flange body (1) and a second flange body (2) which are arranged at the two ends of a connecting tube (5) and matched with each other. The connecting tube (5) is formed by splicing a first short tube body (6) and a second short tube body (7), and the center of the first short tube body (6) and the center of the second short tube body (7) are located on the same axis. The inner diameter of the first short tube body (6) and the inner diameter of the second short tube body (7) are equal. The outer diameter of the first short tube body (6) is 10-40 mm larger than that of the second short tube body (7). A step is formed on the spliced joint of the first short tube body (6) and the second short tube body (7). The first flange body (1) and the second flange body (2) are each provided with a central through hole (3), and the central through holes (3) are concentric. The special flange is simple in structure and ingenious in design; when the special flange is used, the flange can be supported through the step-type structure on the outer portion of the connecting tube so that the flange can be stably supported; accordingly, the special flange is safe and convenient to use.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of special flange.
Background technique
At present, existing pair of flange short tube, intermediate portion is isometrical connecting tube, for the flange of this structure, can not be fixed well according to special situation.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of special flange.
In order to reach above object, the technological scheme that the present invention adopts is: a kind of special flange, comprise the first flange cooperatively interacted and the second flange that are arranged on connecting tube two ends, described connecting tube is in the first short tube on same axis and the second short tube by center and splices and form, described first short tube is identical with the internal diameter of the second short tube, external diameter 10 ~ the 40mm larger than the external diameter of the second short tube of described first short tube, form a step in the stitching portion of the first short tube and the second short tube, described first flange and the second flange are provided with same central through bore.
The invention has the beneficial effects as follows: structure of the present invention is simple, designs ingenious, so in use, the staircase structural model outside connecting tube can be utilized gently to be erected by flange, play the object of firm support, convenient, safety.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is plan view of the present invention.
In figure: 1-first flange; 2-second flange; 3-central through bore; 4-fixes ear; 5-connecting tube; 6-first short tube; 7-second short tube.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As depicted in figs. 1 and 2, the special flange of one provided by the present invention, comprise the first flange 1 and the second flange 2 cooperatively interacted being arranged on connecting tube 5 two ends, described connecting tube 5 is in the first short tube 6 on same axis and the second short tube 7 by center and splices and form, described first short tube 6 is identical with the internal diameter of the second short tube 7, the external diameter 30mm larger than the external diameter of the second short tube 7 of described first short tube 6, form a step in the stitching portion of the first short tube 6 and the second short tube 7, described first flange 1 and the second flange 2 are provided with same central through bore 3.
Structure of the present invention is simple, designs ingenious, so in use, the staircase structural model outside connecting tube can be utilized gently to be erected by flange, play the object of firm support, convenient, safety.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
