Abstract
The utility model discloses a rotatable flange connection structure, characterized in that the rotatable flange connection structure includes an outer tube and an inner tube, wherein an external diameter of the inner tube is adapted to an inner diameter of the outer tube, the inner tube is sleeved in the outer tube, an external side wall of the inner tube is provided with an annular recess I, the inner wall of the outer tube is provided with an annular recess II at a corresponding position to the annular recess of the inner tube, the outer tube wall is provided with a throughhole communicating with the outer tube annular recess II, a plurality of blocks are stopped between the inner tube annular recess I and the outer tube annular recess II through the throughhole to permanently connect the outer tube and the inner tube. The outer tube and the inner tube are connected through blocks not screws, in this way, after the outer tube and the inner tube are connected completely, it is capable of implementing a rotation of 360 DEG C without disassembly them. Comparing with the existing flange connection mode, the installation and debug are all simple and convenient, and it is capable of saving time and saving labor.
Description
Technical field
The utility model relates to a kind of link, particularly a kind of rotatable flanged connecting structure.
Background technique
Pipeline often uses flange connection in installation.It is by screw two flange plate butt joints to be fixed that existing flange connects.This flange connection is wasted time and energy, and particularly during high-lift operation, inconvenience more seems.And after pipeline connects by this flange mode, with regard to relative fixed, can't rotate between the two tubes, when needs are debugged, just must dismantle the screw on the flange, two tubes be separated, after the dismounting, water in the pipe just oozes out, and has promptly influenced working environment, wastes time and energy again.
The model utility content
The purpose of this utility model is to overcome the prior art defective, and it is simple and convenient to provide a kind of installation to connect, and need not to dismantle the rotatable flanged connecting structure that can realize 360 ° of rotations.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of rotatable flanged connecting structure, it is characterized in that: described rotatable flanged connecting structure includes outer tube and interior pipe, the external diameter of interior pipe and the internal diameter of outer tube are suitable, interior pipe box is gone in the outer tube, offer a circular groove I on the tube wall in the outside of interior pipe, outer tube wall and the corresponding position of interior pipe circular groove also are provided with circular groove II, described outer tube wall is provided with a through hole that is communicated with outer tube circular groove II, between pipe circular groove I and the outer tube circular groove outer tube is fixedlyed connected with interior pipe in a plurality of fixture blocks are stuck in by this through hole.
The beneficial effects of the utility model are: fixedly connected rather than screw is connected by fixture block for outer tube of the present utility model and interior pipe, like this, after installing between outer tube and the interior pipe, need not dismounting between the two and can realize 360 ° of rotations.Compare existing flange connection, Installation and Debugging are simple and convenient, and are time saving and energy saving.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1 is the utility model specific embodiment structural representation;
Embodiment
As shown in Figure 1, a kind of rotatable flanged connecting structure, include outer tube 1 and interior pipe, the external diameter of interior pipe 4 and the internal diameter of outer tube 1 are suitable, interior pipe 4 is inserted in the outer tube 1, offer a circular groove I7 on the tube wall in the outside of interior pipe 4, outer tube wall and the corresponding position of interior pipe circular groove I7 also are provided with circular groove II6, described outer tube 1 tube wall is provided with a through hole that is communicated with outer tube circular groove II6, between pipe 4 circular groove I7 and the outer tube circular groove II6 outer tube 1 is fixedlyed connected with interior pipe 4 in a plurality of fixture blocks 3 are stuck in by this through hole.
Fixedly connected rather than screw is connected by fixture block 3 for outer tube 1 of the present utility model and interior pipe 4, after installing between outer tube 1 and the interior pipe 4 like this, need not dismounting between the two and can realize 360 ° of rotations.Compare existing flange connection, Installation and Debugging are simple and convenient, and are time saving and energy saving.
Outer tube 1 inwall among the embodiment is provided with a step 2, and the end face of interior pipe 4 props up this step 2.Outer tube 1 and interior pipe 4 directly can not be subjected to displacement to direction like this.Outer tube 1 inwall is provided with many annular containing grooves, all is provided with an O-ring seal 5 in every annular containing groove.Seal ring 5 can prevent that liquid from oozing out from the slit of outer tube 1 and interior pipe 4.
Certainly, protection domain of the present utility model is not limited only to above-mentioned mode of execution, and any improvement to the utility model unsubstantiality all should be within protection domain of the present utility model.
Claims (3)
1. rotatable flanged connecting structure, it is characterized in that: described rotatable flanged connecting structure includes outer tube and interior pipe, the external diameter of interior pipe and the internal diameter of outer tube are suitable, interior pipe box is gone in the outer tube, offer a circular groove I on the tube wall in the outside of interior pipe, outer tube wall and the corresponding position of interior pipe circular groove also are provided with circular groove II, described outer tube wall is provided with a through hole that is communicated with outer tube circular groove II, between pipe circular groove I and the outer tube circular groove outer tube is fixedlyed connected with interior pipe in a plurality of fixture blocks are stuck in by this through hole.
