Description
Technical field
The utility model relates to a kind of joint, especially a kind of gas-tpe fitting.
Background technique
At present; The automobile production press workshop all adopts robot automation's production model; Workshop required material when manufactured parts all is to transmit through robot; Because the part of producing is different, robot carries the structure of the terminal-collecting machine sucker layout of carrying also with different, so need be through changing and using different terminal-collecting machines to satisfy production requirement; Because of the required source of the gas of terminal-collecting machine sucker work is to be connected with terminal-collecting machine from robot body is inner, therefore need satisfy the connection usage requirement through gas-tpe fitting.The sub-joint of original terminal-collecting machine tracheae docks the back each other with the female joint of robot interior just can make the source of the gas mutual conduction; Be distributed in the inside of terminal-collecting machine and robot because of the tracheae route; Put in place so can't detect from the outside whether to install between the two to connect; Can occur gas-tpe fitting thus and possibly be in semi-connection state, also be that the sub-joint of terminal-collecting machine tracheae does not insert robot female joint inside fully, thereby cause the existence of gas leak phenomenon.
The Chinese patent notice of authorization number is CN201368288Y; Notice of authorization day is on December 23rd, 2009, and the name of innovation and creation is called " gas circuit rapid pipe joint ", and this application case discloses a kind of gas circuit rapid pipe joint; But comprise negative joint and the male connector of sliding fit in the negative joint passage; Described negative joint comprises a joint cap and a pipeline connector, and described negative joint also comprises one-way valve, and described one-way valve can and produce by male connector phase pushing tow and endwisely slip with conducting; One end of said one-way valve is removable the connection with joint cap, and its other end is removable the connection with a pipeline connector.In this structure, negative joint comprises a joint cap and a pipeline connector, and structurally comparatively complicated, part causes the difficulty of producing and assembling at most easily, but also can bring bigger loss risk.
Chinese patent notice of authorization CN201407393Y; Notice of authorization day is on February 17th, 2010, and the name of innovation and creation is called " a kind of one-way valve ", and this application case discloses a kind of one-way valve; Include the tubular valve body of fluid inlet/outlet; Be provided with the spool that is used for the sealing fluid import in the valve body, the fluid outlet of described valve body is provided with the joint of crossing the mouth of a river with some, and joint has fixed component towards a side of fluid inlet; The fixed component outside is with spring and is used for spool is applied the thrust towards the fluid inlet direction, the valve body importer is sealed to end by spring force at the nature spool.In this structure, spool is receiving under the spring force effect working stability good inadequately, and needs higher precision to cooperate could to keep good unlatching and sealing effect, increase the difficulty of production technology thus, increase labor intensity and cost of production.
Summary of the invention
In order to overcome the deficiency of existing technology, it is a kind of simple in structure that the utility model provides, and cost of production is low, and the gas-tpe fitting of unlatching and good sealing effect.
The utility model solves the technological scheme that its technical problem adopted: a kind of gas-tpe fitting, include the sub-joint of tracheae and the tracheae female joint of tubulose, and be respectively equipped with sub-joint passage of tracheae and tracheae female joint passage in sub-joint of tracheae and the tracheae female joint; Be provided with one-way valve in the said tracheae female joint passage; This one-way valve includes valve seat, spool and stage clip, installs in tracheae female joint passage said valve base sealing, offers the valve opening of conducting tracheae female joint passage on the valve seat; Spool is inserted in the valve opening; End than the sub-joint far-end of tracheae on the spool convexes with seal ring, and the diameter of seal ring is greater than the diameter of valve opening, compression spring sleeve be located on the spool with respect to seal ring place end than far-end; One end of stage clip and valve seat are inconsistent fixing, and the other end is connected fixing with spool.
Further being set to of the utility model: be provided with limiting stopper with respect to what held at the seal ring place than far-end on the said spool; Compression spring sleeve is located on the spool and is positioned at limiting stopper and valve base chamber; The stage clip two ends are inconsistent fixing with limiting stopper and valve seat successively, and the diameter of said limiting stopper is greater than the diameter of valve opening.
Adopt technique scheme; Limiting stopper not only can make stage clip contact at the relative fixed that the top constitutes stage clip and spool, and simultaneously, limiting stopper can also be avoided when the sub-joint jacking force of tracheae is excessive; The situation that spool is ejected valve opening occurs, and improves the stability of spool running.
Further being set to of the utility model: said seal ring and valve base chamber are provided with the valve opening seal ring, and sub-joint of said tracheae and tracheae female joint interchannel are provided with the channel seal circle.
Further being set to of the utility model: said spool is that column and constitute with valve opening is slidingly matched, and said valve opening seal ring is installed on seal ring and with seal ring is concentric and is provided with, and said channel seal snare is located on the outer wall of the sub-joint of tracheae.
Adopt technique scheme; The valve opening seal ring can constitute seal ring and valve opening is sealed and matched; The channel seal circle can constitute the sub-joint outer wall of tracheae and tracheae female joint vias inner walls is sealed and matched; When seal ring pressed on the valve seat, the valve opening seal ring had promptly constituted the sealing of valve opening, and the channel seal circle promptly constitutes being sealed and matched between sub-joint outer wall of tracheae and tracheae female joint vias inner walls.
Further being set to of the utility model: also be provided with medium channel on the said spool, an end opening of this medium channel is on the spool perisporium, and the other end is opened on the spool and the relative end of the sub-joint passage of tracheae.
Adopt technique scheme, when gas-tpe fitting was in opening state, the two ends of medium channel constituted the conducting of the gentle pipe coupling passage of tracheae female joint passage respectively, and medium channel can improve the flow of medium from the sub-joint passage of tracheae to tracheae female joint passage.
Further being set to again of the utility model: sub-joint of said tracheae and tracheae female joint guide rail guide groove cooperate.
Adopt technique scheme, when the sub-joint of tracheae is inserted in the tracheae female joint, improve when plugging each other along sliding and stable, can one-time-reach-place during insertion.
The beneficial effect of the utility model is: when needs are connected sub-joint of tracheae and tracheae female joint; Only need the sub-joint of tracheae is inserted the tracheae female joint; The sub-joint of tracheae this moment will press on the spool in the tracheae female joint; Make spool move axially and remove being sealed and matched of spool upper sealing ring and valve base chamber along valve opening, sub-joint passage of conducting tracheae and tracheae female joint passage are realized the conducting between sub-joint of tracheae and tracheae female joint thus.If it is not in place that the sub-joint of tracheae does not insert or insert the tracheae female joint, then spool is sealed and matched with the valve seat formation under the effect of stage clip all the time, and keeps the sealing of valve opening.
