Detailed Description
In order to further illustrate the technical means and technical effects adopted by the present invention, the present invention is described in detail below with reference to the examples.
As shown in fig. 6-7, the invention comprises a fixed part, on which a fixed part 1 for assembling at the front end of a pressing part of the connector tail accessory, a ring groove 2 for providing an assembling space for the hose, a connecting part 3 for adapting to the hose and a screwing part 4 arranged at the tail end of the connecting part for screwing with a spiral groove 6 of the inner wall of the hose are arranged, the front end of the connecting part is connected with the bottom 12 of the ring groove, the bottom of the ring groove is connected with the fixed part through a side wall 5 of the ring groove, the whole fixed part, the side wall of the ring groove, the bottom of the ring groove, the connecting part and the screwing part are integrated, and the connecting part is a hollow structure for threading.
The spiral connection part is spiral and the middle part is disconnected, and the disconnection part and the tail end of the connection part form a gap for enabling the spiral connection part to be smoothly screwed with the spiral groove on the inner wall of the hose. The screw pitch of the screwing part is equal to that of the spiral groove, so that the screwing part is matched with the spiral groove to be screwed.
The spiral connection part can be formed by turning up the tail end of the connection part after opening treatment to form a flanging used for being screwed with the spiral groove, after the hose and the fixing part are screwed in place, the front end of the hose is positioned in the annular groove of the fixing part, the spiral connection part is clamped in a certain spiral groove in the inner wall of the hose, and when the hose is pulled outwards, the hose is matched with the spiral groove in the inner wall and the spiral connection part on the fixing part to ensure that the hose has certain tensile property.
The connector tail accessory comprises a fixing part 7 arranged at the tail part of the connector, a pressing piece 8 assembled at the rear end of the fixing part, a sealing piece 9 assembled at the rear end of the pressing piece, a fastener 10 assembled outside the connector shell and the like. When the fixing piece is used with the connector, the fixing part is assembled before the pressing piece, as shown in fig. 4. After the hose 11 and the screwing part of the fixing part are screwed in place, the front end of the hose is positioned in the annular groove of the fixing part, and the screwing part is clamped in a certain spiral groove on the inner wall of the hose. After the fastener is screwed up, the hose is tightly held together with the sealing element, and the fastener is screwed up to make the compressing part withstand the fixed part, and when the hose is outwards pulled, the hose is guaranteed to have certain tensile property through the cooperation of the spiral groove of the inner wall and the screwing part on the fixing part, thereby the tensile ability of the hose is further improved to the fixed part spacing by the compressing part simultaneously.
The structure of the male connector and the fixing member used in cooperation is the same as that of the connector using the fixing member, specifically, the fixing portion of the fixing member is assembled at the tail of the male connector so that the fixing portion of the fixing member is located before the pressing member, as shown in fig. 5, which is not described again.
The fixing part 7 at the tail part of the connector (or the male connector) is positioned in front of the fixing part of the fixing piece, namely the fixing part is assembled between the fixing part and the pressing piece to limit the fixing part, but the tensile property of the hose is further ensured by limiting the fixing part by the pressing piece when the hose is pulled outwards after the fixing part is assembled in front of the pressing piece.
Further, in order to ensure the tensile property of the hose, the width D of the screw part is equal to or slightly greater than or slightly less than the depth D of the spiral groove.
It should be noted that: the terms "side", "front", "rear", "end" and the like used herein to indicate orientation are based on the illustrated orientation or positional relationship, and are used only for the convenience of describing the present invention, and thus should not be construed as limiting the present invention.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and any simple modification, equivalent change and modification made by those skilled in the art according to the technical spirit of the present invention are still within the technical scope of the present invention without departing from the technical scope of the present invention.
