Description

  The present invention relates to a fitting, and more particularly to a fitting having a cover disposed around a fitting body.

  Some fitting members have a cover attached to the periphery of the fitting body. For example, in a female fitting member used as a hydrogen injection nozzle connected to a hydrogen supply hose extending from a dispenser at a hydrogen station, substantially the entire female fitting body is covered with a cover (housing) (Patent Document 1). The cover of the male fitting member constitutes a grip for facilitating the operator's grip, and protects the main components of the female fitting body. The cover is comprised of a plurality of parts and is fixed against movement relative to the female fitting body.

JP, 2016-27280, A

  At a hydrogen station, hydrogen is charged into a hydrogen tank of a fuel cell vehicle under a high pressure condition of usually 70 MPa. Therefore, the hose for hydrogen supply is required to have high pressure resistance, and the rigidity is inevitably high. Therefore, the orientation of the female fitting member connected to such a highly rigid hose is greatly influenced by the orientation of the hose. The direction around the longitudinal axis of the male fitting connected to the tip of the hose is around the longitudinal axis of the hose, in particular since a large force is required to rotate the hose around its longitudinal axis. It will be substantially constrained in direction. Therefore, when attaching and detaching the female fitting member which is a hydrogen injection nozzle to the male fitting member (receptacle) which is a hydrogen supply port of the fuel cell vehicle, the direction of the male fitting member is handled by the operator It may be difficult to work, and the workability of hydrogen filling may be deteriorated. Also, if the female fitting member is rotated by the force received from the hose when gripping the cover and moving the female fitting member to the position of the male fitting member, the gripping position on the cover must be changed Therefore, the female pipe joint member may be dropped when changing the gripping position. Such a problem may occur not only in the hydrogen supply nozzle but also in other joint members.

  An object of the present invention is to provide a pipe joint member in which the direction of the cover disposed around the pipe joint body is not constrained by the direction of the pipe joint body in view of the problems of the prior art described above.

That is, the present invention
A fitting body having a fluid passage,
A tubular cover disposed around the fitting body and pivotally attached to the fitting body about the longitudinal axis of the fitting body;
Providing a fitting member comprising:

  In the pipe joint member, since the cylindrical cover disposed around the pipe joint body is configured to rotate with respect to the pipe joint body, the direction of the cylindrical cover around the longitudinal axis is It is not substantially constrained by the orientation of the fitting body. Therefore, for example, when the worker grips the cylindrical cover to perform work, the gripping position in the circumferential direction of the cylindrical cover can be set to an arbitrary position of the worker regardless of the direction of the pipe joint member It is also possible to make it unnecessary to change the gripping position of the tubular cover when the fitting body is pivoted around the longitudinal axis. In particular, in the case where a pipe member such as a hose is connected to the pipe joint body, the pipe body may be constrained in the direction around the longitudinal axis by the force received from the pipe member. Also, the direction of the cylindrical cover can be set to any direction regardless of the direction of the fitting body.

  Specifically, the tubular cover is a front cover member removably and rotatably attached around the fitting body from the front end side of the fitting body, and around the fitting body. And a rear cover member removably and rotatably attached from the rear end side of the pipe joint body, wherein the front cover member and the rear cover member are respectively attached to the pipe joint body In addition, they can be engaged with each other in the pivoting direction to pivot integrally with the fitting body.

Also,
The fitting member is a female fitting member such that the fitting body is adapted to receive a male fitting member from the front end of the fitting body into the fluid passage.
The fitting body is
A locking member for fixedly connecting a male type pipe joint member received in the fluid passage to the pipe joint body, the locked position for fixedly connecting the male type pipe joint body, and releasing the fixed connection A locking member displaceable between an unlocking position,
A locking operation member which is displaceable in the direction of the longitudinal axis between a connecting position for holding the locking member in the locking position and a mounting and demounting position for permitting the locking member to be in the unlocking position;
Equipped with
An opening is formed between the front cover member and the rear cover member of the cylindrical cover, and the locking operation member has an operating portion that protrudes to the outside of the cylindrical cover through the opening. Can.

  In this case, furthermore, the locking operation member is an engaging member which engages with the locking member for a locking operation, and the engaging member is rotatably attached to the engaging member around the longitudinal axis. And a cylindrical operating member which is displaced in the front-rear direction, and the operating member has the operating portion and is rotatable with respect to the pipe joint body together with the cylindrical cover. it can.

  Since the operating member rotates together with the cylindrical cover, the operability of the operating member can be prevented from being influenced by the direction of the pipe fitting body.

In particular,
It further comprises an annular sliding member that is circumferentially slidable on the outer peripheral surface of the fitting body,
The tubular cover may be pivotably attached to the fitting body via the annular sliding member.

  At this time, the tubular cover further has a locking through hole which penetrates in the radial direction, the fixing screw is screwed to the annular sliding member through the locking through hole, and the head of the fixing screw is By engaging with the inner peripheral surface of the locking through hole, the tubular cover can be fixed to the annular sliding member in the direction and circumferential direction of the longitudinal axis.

  Such a configuration makes it possible to reduce the wall thickness of the cylindrical cover and at the same time prevent the head of the fixing screw from protruding from the cylindrical cover. Further, since the cylindrical cover is not strongly tightened by the fixing screw, for example, when the cylindrical cover is made of a material such as resin, which is relatively low in rigidity and wear resistance, the cylindrical cover is tightened by the fixing screw. It is possible to prevent the fixing screw from being loosened due to breakage due to an applied force or abrasion or deformation of the cylindrical cover.

Preferably,
It further comprises a first rolling member and a second rolling member disposed between the outer peripheral surface of the pipe fitting body and the inner peripheral surface of the cylindrical cover,
A first holding recess for partially receiving and rotatably holding the first rolling member is formed on the outer peripheral surface of the pipe coupling body, and the second rolling member is partially formed on the inner peripheral surface of the cylindrical cover. A second retaining recess is formed for receiving and rotatably holding the
The first rolling member and the second rolling member are in contact with each other when the tubular cover is pivoted with respect to the pipe fitting main body so as to limit the pivoting range of the tubular cover. Can.

  By restricting the rotation range of the cylindrical cover, for example, when a cable or the like extends in the cylindrical cover, it is possible to prevent excessive twisting of the cable.

  Hereinafter, an embodiment of a pipe joint member concerning the present invention is described based on an attached drawing.

  The pipe joint member according to one embodiment of the present invention is, as shown in FIG. 1, a female pipe joint main body (pipe joint main body) 12 and a cylinder rotatably attached around the female pipe joint main body 12. It is a female type pipe joint member 10 which consists of an annular cover 30. The female fitting member 10 is a hydrogen injection nozzle attached to a hydrogen supply hose (not shown) of a hydrogen station, and a male fitting member (not shown) which is a receptacle connected to a hydrogen tank of a fuel cell vehicle The hydrogen station is detachably connected to the hydrogen station and fluidly connects the hose of the hydrogen station and the male joint member to fill the hydrogen tank of the fuel cell vehicle with high pressure hydrogen from the hydrogen station. The female pipe coupling member 10 is provided with a communication terminal at the front end of the cylindrical cover 30 as described later, and when the female pipe coupling member 10 is connected to the corresponding male pipe coupling member, the communication terminal corresponds The position is opposed to the corresponding communication terminal provided on the male pipe coupling member, and information can be transmitted and received between the communication terminals.

  The female fitting body 12 has a configuration substantially the same as that disclosed in the above-mentioned Patent Document 1, and thus the details thereof will be omitted. However, the front end 14 for receiving and coupling the corresponding male fitting member and the hose It has a rear end 16 to be mounted and a fluid passage 18 extending in the direction of the longitudinal axis L from the front end 14 to the rear end 16. The female fitting body 12 further includes a locking member 20 for fixedly connecting the male fitting member received in the fluid passage 18, and a locking operation member 22 for operating the locking member 20. In the locking member 20, a locking projection 20b protruding radially inward at the front end 20a engages with an engaging groove formed on the outer peripheral surface of the male pipe joint member to fix and connect the male pipe joint member And the locking projection 20b is displaced radially outward from the locking position to the position shown in the figure so as to be displaceable between the locking position for releasing the fixed connection with the male pipe joint member . In addition, the locking operation member 22 is displaced rearward (left in the figure) in the direction of the longitudinal axis L from the connection position to the locking position to hold the locking member 20 in the locking position, and becomes the illustrated position. Is displaceable in the front-rear direction (left and right direction as viewed in the drawing) in the direction of the longitudinal axis L with respect to the attachment / detachment position where it is permitted to be the unlocked position. The female tube fitting main body 12 has a chuck structure in which the male tube fitting member is detachably connected by the locking member 20 and the locking operation member 22 as described above.

  The cylindrical cover 30 is rotatably mounted on the periphery of the female pipe fitting body 12 via an annular sliding member 32 mounted slidably on the outer peripheral surface 12 a of the female pipe fitting body 12 in the circumferential direction. It is done. The cylindrical cover 30 is formed of a cylindrical front cover member 34 and a rear cover member 36, respectively. As shown in FIG. 2, the front cover member 34 protrudes from the front cylindrical portion 38 radially outward from the front cylindrical portion 38 surrounding the periphery of the female fitting body 12 and extends in the front-rear direction And an elongated front raised portion 40. Similarly, the rear cover member 36 has a rear cylindrical portion 42 surrounding the periphery of the female fitting body 12 and an elongated rear raised portion 44 protruding radially outward from the rear cylindrical portion 42 and extending in the front-rear direction . The front raised portion 40 extends further rearward than the rear end 38 a of the front cylindrical portion 38. When front cover member 34 and rear cover member 36 are attached to female fitting body 12 respectively, rear end portion 40a of front raised portion 40 is inserted into and engaged with rear raised portion 44 Be done. As a result, the front cover member 34 and the rear cover member 36 engage with each other in the rotational direction, and rotate integrally with the female pipe fitting body 12. Also, a circumferentially extending opening 46 is formed between the rear end 38 a of the front cylindrical portion 38 and the front end 42 a of the rear cylindrical portion 42. The female pipe coupling member 10 is configured to grip and operate mainly the rear cover member 36 of the cylindrical cover 30.

  As shown in FIG. 1, the front cover member 34 constitutes a major part of the front cover member 34 and holds a communication terminal 72 described later from the outside, and a front cover outer member 34-1, and a front cover main body A front cover inner member 34-2 is fixed to the inside of 34-1 and holds the communication terminal 72 from the inside, and a fitting portion 48 projecting radially inward is formed on the front cover inner member 34-2. It is provided. The front cover member 34 is fitted around the female pipe joint body 12 so that the inner peripheral surface 48 a of the fitting portion 48 fits with the outer peripheral surface 12 a of the front end portion of the female pipe joint body 12. It is attached from the side. An annular groove 50 is formed on the outer peripheral surface 12 a of the female pipe coupling body 12, and the front cover member 34 is provided from the front with respect to the female pipe coupling body 12 by the stop ring 52 attached to the annular groove 50. It is held. As shown in FIG. 3, the stop ring 52 is composed of a front arc 52a and a rear arc 52b bent parallel to each other in an arc, and a connecting part 52c connecting them. When the stop ring 52 is attached to the annular groove 50 of the female fitting body 12, it is between the front side 50 a of the annular groove 50 and the front side 48 b of the fitting portion 48 of the front cover member 34. , And is pressed in the direction of the longitudinal axis L to press the fitting portion 48 rearward. The front cover member 34 pressed rearward by the stop ring 52 is locked to the step 54 on the outer peripheral surface 12 a of the female pipe fitting body 12 by the rear side surface 48 c of the fitting portion 48, Lateral displacement is blocked. That is, the front cover member 34 is fixed in the direction of the longitudinal axis L with respect to the female fitting body 12 by the fitting portion 48 being pinched by the step 54 and the stop ring 52.

  The rear cover member 36 is fitted around the female fitting body 12 from the side of the rear end 16. Specifically, the rear cover member 36 is fitted to the annular sliding member 32, and a fixing screw is screwed to the annular sliding member 32 through a locking through hole 56 formed to penetrate in the radial direction. When the head 58a of 58 engages with the inner peripheral surface 56a of the locking through hole 56, the annular sliding member 32 is fixed in the front-rear direction and the circumferential direction. The rear cover member 36 fixed to the female pipe fitting main body 12 via the annular sliding member 32 is fixed to the female pipe fitting main body 12 in the front-rear direction but can be rotated in the circumferential direction It has become. When a member is fixed by a screw, usually, a screw is made to sandwich and fasten a member to be fixed between the screwed member and the head of the screw. The rear cover member 36 is fixed to the annular sliding member 32 by engaging the head 58a of the fixing screw 58 with the inner peripheral surface 56a of the locking through hole 56 as described above. By adopting such a fixing method, the rear cover member 36 can not be tightened by a strong force, and therefore, when the rear cover member 36 is made of a material such as resin that is relatively low in rigidity and wear resistance, the rear cover It is possible to prevent the fixing screw 58 from being loosened when the member 36 is broken by the tightening force of the fixing screw 58 or when the rear cover member 36 is worn or deformed. Further, even if the wall thickness of the rear cover member 36 is reduced, the fixing screw 58 can be prevented from projecting outward.

  The locking operation member 22 is rotatably attached around the longitudinal axis L to the engagement member 60 and the engagement member 60 having the front end 60 a engaged with the locking member 20, and extends to the outside of the cylindrical cover 30. It comprises the operating member 62 which extends. The engagement member 60 is a cylindrical member extending inward of the front cylindrical portion 38 of the front cover member 34 in the direction of the longitudinal axis L from the front end portion 60a to the rear, and is biased forward by the spring 63. ing. The operating member 62 has a cylindrical mounting portion 62a attached to slide in the circumferential direction on the outer peripheral surface 60b of the engaging member 60, and the front cover member 34 and the rear cover member 36 from the cylindrical mounting portion 62a. And an operating portion 62 b extending outward through the opening 46 between the rear cover members 36. As shown in FIG. 2, the operating portion 62 b extends in the circumferential direction along the outer peripheral surface 42 b of the rear cylindrical portion 42, and has a C shape having a notch formed at a position corresponding to the rear raised portion 44. have. Since the engaging member 60 and the operating member 62 are fixed in the direction of the longitudinal axis L, by operating the operating portion 62 b of the operating member 62 in the direction of the longitudinal axis L, the engaging member 60 and the operating member 62 are elongated. The direction of the axis L is displaced. Therefore, by operating the operating portion 62b located outside the cylindrical cover 30 in the direction of the longitudinal axis L, the locking member 20 located inside the cylindrical cover 30 can be operated between the locking position and the unlocking position. It can be done. On the other hand, the operation member 62 is rotatable relative to the engagement member 60, and when the cylindrical cover 30 is rotated about the longitudinal axis L with respect to the female fitting body 12, the rear raised portion 44 Are engaged in the circumferential direction and rotate with the cylindrical cover 30. Since the engagement member 60 is biased by the spring 63 and receives a relatively large frictional resistance at the contact portion with the spring 63 and the locking member 20, a relatively large force is required to turn the engagement member 60. And if it is forced to rotate in such a state where a large frictional resistance is generated, wear will also occur between the members, but as described above, the operating member 62 may rotate independently. As a result, it is possible to realize smooth rotation and to prevent wear between members. In addition, although such an effect can not be produced, in order to simplify the structure, the engaging member 60 of the locking operation member 22 and the operation member 62 may be formed as an integral member. That is, a cylindrical portion extending rearward of the front cylindrical portion 38 of the front cover member 34 from the front end portion 60a engaging the locking member 20 with the locking member 20; and a front cover member from this cylindrical portion It may also be a single piece having an operating portion 62b which extends through the opening 46 between 34 and the rear cover member 36 to the outside of the rear cylindrical portion 42.

  The female pipe coupling member 10 includes a swivel mechanism for rotatably attaching the cylindrical cover 30 to the female pipe coupling body 12. The swivel mechanism, as shown in FIG. 4, is disposed around a female tube fitting body (inner member) 12 having an outer circumferential surface 12b with a circular cross-sectional circle, and the female tube fitting body 12 and has a circular cross-sectional circle. A first rolling member 64 disposed between an annular sliding member (outer member) 32 having a circumferential surface 32 a, an outer circumferential surface 12 b of the female pipe fitting main body 12 and an inner circumferential surface 32 a of the annular sliding member 32 And a second rolling member 66. Two first holding recesses 68 are formed on the outer peripheral surface 12b of the female pipe fitting main body 12 at positions opposed in the radial direction, and the positions opposed to the inner peripheral surface 32a of the annular sliding member 32 in the radial direction similarly The two second holding recesses 70 are formed in the. The first rolling member 64 is partially received in the first holding recess 68 and rotatably held therein. Similarly, the second rolling member 66 is partially received in the second holding recess 70 and rotatably held therein. The first rolling member 64 and the second rolling member 66 are both spherical members, and are arranged at positions aligned with each other in the direction of the longitudinal axis L. The first rolling member 64 and the second rolling member 66 may have other shapes, such as a circular cylinder or a barrel, whose cross section is circular.

  When the cylindrical cover 30 rotates with respect to the female pipe fitting body 12, the first rolling member 64 is held in the first holding recess 68 and its position is maintained, while the second rolling member 66 is a cylinder. It is displaced circumferentially around the longitudinal axis L together with the cover 30. At this time, the first rolling member 66 and the second rolling member 68 receive the first holding recess 68 according to the frictional force received from the outer peripheral surface 12 b of the female pipe fitting main body 12 and the inner peripheral surface 32 a of the annular sliding member 32. The rotation of the annular sliding member 32 relative to the female fitting body 12 is smoothened by rotating in the second holding recess 70 respectively. When the cylindrical cover 30 is rotated clockwise with respect to the female fitting body 12 as viewed in FIG. 4, the second rolling member 66 watches the first rolling member 64 as shown in FIG. 5. Contact in the direction of rotation. Therefore, the cylindrical cover 30 is further restricted from pivoting clockwise from the position of FIG. Similarly, when the cylindrical cover 30 is turned counterclockwise as viewed in FIG. 4 with respect to the female pipe fitting main body 12, the second rolling member 66 becomes the first rolling member 64 as shown in FIG. 6. Abut against in the counterclockwise direction. Therefore, the cylindrical cover 30 is further restricted from rotating in the counterclockwise direction from the position shown in FIG. That is, in the swivel mechanism, when the first rolling member 64 and the second rolling member 66 abut in the rotational direction, the annular sliding member 32 as the outer member and the cylindrical cover 30 fixed thereto are rotated. It is designed to limit the range. In the swivel mechanism, as described above, the first rolling member 66 and the second rolling member 66 facilitate the rotation between the female fitting body 12 as the inner member and the annular sliding member 32 as the outer member. The rotational range of the annular sliding member 32 and the cylindrical cover 30 fixed thereto is limited by the rolling member 68 abutting in the circumferential direction, and a structure only for limiting the rotational range is separately provided. Since it is not necessary to provide, the structure can be simplified as compared with the conventional one. In the embodiment, the first rolling member 64 and the second rolling member 66, and the first holding recess 68 and the second holding recess 70 are disposed two by two, respectively, whereby the rotation range of the cylindrical cover 30 is obtained. Is set to less than 180 °, but for example, three rotations are arranged at equal intervals, and the rotation range is less than 120 °, or only one is arranged less than 360 °, according to the desired rotation range The arrangement can also be changed as appropriate.

  The front cover member 34 includes a communication terminal 72 provided on the front end portion 34a, a communication cable 74 extending rearward from the communication terminal 72, and a connector terminal 76 connected to the rear end of the communication cable 74. A communication material 78 is provided. The connector terminal 76 is connected to a corresponding connector terminal (not shown) attached to a communication cable connected to the controller of the hydrogen station dispenser. The communication cable 74 extends rearward from the communication terminal 72 through the inside of the cable hole 80 provided on the front raised portion 40 of the front cover member 34 on the outside of the female fitting body 12 and further to the rear. It extends inside the rear cover member 36 through a cable groove 82 provided so as to open radially inward at the raised portion 44 and extends further to the rear than the rear end 36 a of the rear cover member 36. When the female pipe joint member 10 is connected to the corresponding male pipe joint member, the communication terminal 72 is positioned opposite to the corresponding communication terminal similarly disposed on the male pipe joint member, Infrared signals are transmitted / received to / from the corresponding communication terminals. The communication means is not limited to infrared rays, and may be wireless communication means using electromagnetic waves in other frequency bands.

  The rear portion 74 a of the communication cable 74 is held on the outer peripheral surface of the hose by a spiral tube wound around the hose connected to the rear end 16 of the female fitting body 12. Therefore, when the cylindrical cover 30 is rotated relative to the female pipe fitting body 12, the communication cable 74 is held on the front portion 74b held in the cable hole 80 of the front cover member 34 and the outer peripheral surface of the hose. Twisting will occur with the rear portion 74a. When the rotation range of the cylindrical cover 30 is not limited, the cylindrical cover 30 is largely rotated and a large load is applied to the communication cable 74, the communication cable 74 is broken, the communication terminal 72 or the like There is a possibility that the connector terminal 76 may be detached. However, in the female pipe joint member 10, since the rotation range of the cylindrical cover 30 is limited by the above-mentioned swivel mechanism, the cylindrical cover 30 is rotated as the communication cable 74 is given a large load. It is possible to prevent the disconnection of the communication cable 74 and the like with the rotation of the cylindrical cover 30 without causing the problem.

  The tubular cover 30 is removably attached to the female fitting body 12 as described above, and in particular the front cover member 34 can easily be a female fitting with the communication material 78 as described below. It can be removed from the main body 12.

  When removing the front cover member 34, first, the fixing screw 58 fixing the rear cover member 36 to the annular sliding member 32 is removed (FIG. 7). Although only one fixing screw 58 is shown in the drawing, similar fixing screws 58 are disposed at positions 90 ° circumferentially on both sides from the illustrated fixing screw 58, respectively. Next, the rear cover member 36 was passed through a hose (not shown) attached to the rear end 16 of the female fitting body 12 and a communication cable 74 extending rearward from the front cover member 34 in the front-rear direction. In the state, it is displaced rearward from the female fitting body 12 (FIG. 8). At this time, a gap sufficient for passing the connector terminal 76 is formed between the inner peripheral surface 36 b of the rear cover member 36 and the hose, and the rear cover member 36 passes the connector terminal 76 inside the connector terminal 76. It can be displaced to a position further rearward than that. Next, the stop ring 52 attached to the annular groove 50 of the female fitting body 12 is removed (FIG. 9), and the front cover member 34 is displaced forward (FIG. 10). As a result, the communication member 78 is also removed from the female fitting body 12 together with the front cover member 34. For example, when the communication material 78 breaks down due to breakage of the communication terminal 72 or disconnection of the communication cable 74, the communication material 78 is removed together with the front cover member 34 in this way, and a new communication material is obtained. The communication material 78 can be replaced by attaching the front cover member 34 having the member 78 to the female fitting body 12 in the reverse procedure to the above. In the replacement operation, the rear cover member 36 does not have to be displaced to the rear of the connector terminal 76. For example, a position where the front end 36c of the rear cover member 36 is in contact with the rear end 16 of the female pipe joint body 12 Position the rear cover member 36 so that the connector terminal 76 is still behind the rear cover member 36, and when removing the front cover member 34, the communication cable 74 and the connector terminal 76 along the hose. The inside of the rear cover member 36 may be pulled forward. As described above, in the female pipe coupling member 10, the communication material 78 can be easily replaced without disassembling the female pipe coupling body 12.

  Although one embodiment of the present invention has been described, the present invention is not limited to this, and various modifications are possible. For example, the pipe joint member according to the present invention may be a pipe joint member used for flowing other gas or liquid instead of a hydrogen supply nozzle, or a male pipe joint member not a female type It may be
