Abstract
The utility model discloses a compressed air line force-unloading head-varying device, characterized in that: the compressed air line force-unloading head-varying device is composed of an inner tube (1) and an outer tube (3), wherein part of the inner tube (1) is sleeved in the inner cavity of the outer tube (30 and the inner tube (1) and the outer tube (3) counter rotate and are in sealed fit with each other and a cylindrical surface of the inner tube (1) is provided with an annular groove (5) and the outer tube (3) is provided with a positioning screw (6) to form a positioning fit with the annular groove (5) and a cylindrical surface of the inner tube (1) is provided with at least two sealing rings (2) in close fit with the inner cavity of the outer tube. One end of the outer tube is provided with a screwed joint (40 and one end of the inner tube (1) is provided with a rubber hose connector (8). The beneficial effects of the utility model are that: because of the counter rotation of the inner tube and the outer tube, the torsion of the rubber hose is broken and the hose is prevented from being disengaged and furthermore the human is prevented from being hurt hose during disassembling and assembling the compressed air line in engineering construction and the construction safety is increased.
Description
Technical field
The utility model relates to a kind of connection set that is used for pressing wind (pressurized air) delivery line, especially can keep under the sealing situation, guarantees the pipeline connecting device of the personal safety when flexible pipe presses wind to carry unimpeded or protection personnel disassembling pipe.
Background technique
At present, be used to carry the general main employing steel pipe of pipeline of pressing wind, adopt sebific duct to connect at movable position, sebific duct connects and is made up of sebific duct and fixed connector.When sebific duct was opened for extended state by the rolling state, sebific duct produces warping force can turn round the flat hose pipeline, or personnel meet with the Personal Risk when dismantling the glue head.Extensively retrieve at the problems referred to above, still find no the solution of effect.
The model utility content
The purpose of this utility model is exactly in order to solve the problem that sebific duct connection set in the existing pressure ventilation pipe can not crack sebific duct torsion; a kind of new pressure ventilation pipe that provides unloads power and becomes head unit; personal safety when the winding torsion that this device can not only crack flexible pipe guarantees that flexible pipe presses wind to carry unimpeded or protection personnel disassembling pipe, and can rotate under the sealing situation keeping.
The technical scheme in the invention for solving the technical problem is:
A kind of pressure ventilation pipe unloads power and becomes head unit, it is characterized in that: it is made up of with an outer tube that is connected with sebific duct an interior pipe that is connected with pressure ventilation pipe, the part of interior pipe is set in the inner chamber of outer tube 3, they can rotate relatively and be and be sealed and matched, the cylndrical surface of interior pipe is provided with circular groove one, outer tube is provided with screw hole, and screw hole is provided with positioning screwn and cooperates with circular groove formation location.
According to above-mentioned basic technical scheme, following further technological scheme can be arranged:
The cylndrical surface of interior pipe is provided with the seal ring that twice and outer tube bore at least are sealed and matched;
Outer tube one end is provided with the inipple that is connected with pressure ventilation pipe, and an end of interior pipe 1 is provided with rubber hose coupling.
The utility model working principle is that when air line drew the sebific duct of folding because of need of work extends, under the effect of sebific duct torsion, inner and outer pipe generation relative rotary motion cracked torsion.Seal ring and limit structure are arranged, sealing and can not coming off when guaranteeing rotation between the inner and outer pipe.
The beneficial effects of the utility model are:
By using this model utility pressure ventilation pipe power of unloading to become head unit, make inner and outer pipe generation relative rotary motion, crack the torsion of sebific duct, flexible pipe disconnection whipping casualty accident takes place when having avoided in engineering construction the dismounting air line, promote working security.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is that the utility model pressure ventilation pipe power of unloading becomes head unit and connects and sectional structure chart in pipeline.
Embodiment:
As shown in Figure 1, a kind of pressure ventilation pipe unloads power and becomes head unit, it is made up of with an outer tube that is connected with sebific duct 3 an interior pipe 1 that is connected with pressure ventilation pipe, the part of interior pipe 1 is set in the inner chamber of outer tube 3, they can rotate relatively, the cylndrical surface of interior pipe 1 is provided with circular groove 5 one, and outer tube 2 is provided with screw hole 7, and screw hole 7 is provided with positioning screwn 6 and cooperates with circular groove 5 formation location.In pipe 1 cylndrical surface be provided with the seal ring 2 that twice at least cooperate with outer tube 2 bore seal.Outer tube 3 one ends are provided with and pressure ventilation pipe inipple 4, and an end of interior pipe 1 is provided with rubber hose coupling 8.
During use, the inipple 4 of outer tube 3 is connected with main pressure ventilation pipe adaptor spool 9, the following end connector 8 of interior pipe 1 is connected with sebific duct again, and the sebific duct colligation is firm.When pipe rotates in sebific duct drives the change head unit, keep sealing under seal ring 2 effects, the positioning screwn 6 on outer tube cooperates with circular groove 5, and inner and outer pipe can not disconnected.
Claims (3)
1, a kind of pressure ventilation pipe power of unloading becomes head unit, it is characterized in that: it is made up of a pipe (1) and an outer tube (3) in one, the part of interior pipe (1) is set in the inner chamber of outer tube (3), they can rotate relatively and be and be sealed and matched, the cylndrical surface of interior pipe (1) is provided with one circular groove (5), outer tube (3) is provided with screw hole (7), and screw hole (7) is provided with positioning screwn (6) and cooperates with circular groove (5) formation location.
