Description

Field of the InventionThe present invention relates to a connector and, more particularly, to a quick-action closure connector for hydraulic pipes.Prior ArtIn existing bicycles, during travel under various road conditions, there is often a need to change the front end. When changing the front end, a hydraulic pipe which is located between the link and the disc brake and is connected to the two has to be removed in order to be able to mount the new front end. After the new front end has been assembled, the hydraulic pipe must be attached again. This process is not only monotone and cumbersome, but also the hydraulic pipe is easily crushed, deformed, broken and damaged by repeated joining. Therefore, the development of a quick-release terminal which is easy to remove presents a problem in this technical field to be solved urgent.Object of the InventionA quick-action lock terminal includes a first terminal, a second terminal, and at least one groove, wherein each of the first terminal and the second terminal is formed in a hollow tube shape, and one end of the first terminal and one end of the second terminal are detachably connected to each other so that the first terminal and the second terminal are continuously connected to each other, wherein at least one groove is recessed into the inner wall of the other end of the first terminal or the second terminal.Here, the first port includes: a first connector tube through which a first flow channel passes, the first connector tube having at least one connector tube-side bore passing through the ring side wall of the first connector tube, and the at least one connector tube-side bore being continuously connected to the first flow channel; a lock-push ring surrounding the outer periphery of the first connector tube and slidable relative to the first connector tube to close or open at least one connector tube-side bore; a first ring inner wall annularly protruding from the inner wall of a first sleeve, wherein a lock-push spring abuts at both ends thereof against the lock-push ring and the first ring inner wall and applies an abutting pressure to the lock-push ring; and two connector recesses respectively passing through both opposite sides of the first sleeve.Here, a second flow passage is provided in the second port, the second port including: a second plug pipe through which a plug pipe flow passage continuously connected to the second flow passage extends; a blocking member disposed near the open end of the second port and slidable within the second flow passage relative to the second plug pipe to open or close the second flow passage; a blocking spring having both ends respectively abutting against the blocking member and the second plug pipe to apply an abutting pressure to the blocking member; and two snap clip grooves respectively recessed on the two opposite sides of the second sleeve.When an end of the first port and an end of the second port abut each other, the lock-push ring receives the pressure displacement of an end of the second port and at least one plug-pipe-side bore is opened, the lock member receives the pressure displacement of the first plug pipe and the second flow channel is opened. At this time, the first flow channel is continuously connected to at least one plug-pipe-side bore and the second flow channel is continuously connected to the plug-pipe flow channel.Further, the quick-action lock terminal according to the present invention includes a snap-fit handle having a bent rod shape with a lifting handle and two snap-fit feet extending from both ends of the lifting handle, wherein when one end of the first terminal and one end of the second terminal abut each other, the two snap-fit recesses are respectively aligned with the two snap-fit strap grooves, at which time the two snap-fit feet of the snap-fit handle are inserted into the two snap-fit recesses and the two snap-fit strap grooves which are respectively aligned.In use, the two connecting pipes are respectively connected to one end of the first pipe joint portion and the second pipe joint portion, wherein when one of the connecting pipes is pushed into the first annular gap along the outer wall of the first pipe joint portion, the outer wall of the connecting pipe corresponds to the plural grooves, and the first flow channel is continuously connected to the connecting pipe, wherein when the other connecting pipe is pushed into the second annular gap along the outer wall of the second pipe joint portion, the second flow channel is continuously connected to the connecting pipe.Note that when a connection pipe is connected to the first port, the outer surface and the inner surface of the connection pipe are respectively compressed by the first shell and the first plug pipe to achieve press-fitting and prevent fluid leaks. By the arrangement of the at least one groove, the tension of the compressed connecting pipes caused by the compression can be dissipated in the direction of the groove, so that the connecting pipes do not easily break and be damaged by long-term compression.Brief Description of the DrawingsFIG. 1 is a perspective view of a preferred embodiment of the present invention; FIG. 2 is a sectional view of the preferred embodiment of the present invention; FIG. 3 is a sectional view of the preferred embodiment of the present invention after connection; Fig. 4 is a sectional view of another preferred embodiment according to the present invention.DETAILED DESCRIPTION OF THE EMBODIMENTReference is made to the preferred embodiment shown in Figures 1 to 3.
