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 first short tube body (6) is internally provided with an internal thread, and the second short tube body (7) is externally provided with an external thread. The first short tube body (6) is in threaded connection with 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 two central through holes (3) are concentric. The special flange is simple in structure and ingenious in design; when the special flange is used, the length of the flange short tube can be changed through threaded connection between the first short tube body and the second short tube body as required; accordingly, the special flange can meet various use requirements, and the application range of the flange short tube can be greatly expanded.
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, normal length is non-adjustable, is difficult in a special case satisfy the demand.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of length-adjustable 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, internal thread is provided with in described first short tube pipe, outside thread is provided with outside described second short tube pipe, be threaded between described first short tube and the second 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, design ingenious, so in use, can utilize and state being threaded between the first short tube and the second short tube and change the length of flange short tube as required, be adapted to various demand, greatly increase the using scope of flange short tube.
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.
