Description

  The present invention relates to a joint main body device that constitutes a main portion of the pipe joint, and a coupling ring member used in the joint main body device, in particular, in a pipe joint for connecting and connecting pipe members to be connected. It is possible to effectively absorb vibrations etc. that are sometimes transmitted to the pipe joint.

  In general, in various types of equipment using pressurized fluid such as pressurized air, for example, manual pneumatic tools, the inlet port and outlet port that are the flow path of the pressurized fluid for operation, Pressure resistance to allow one end base side of the pipe joint device to be attached and fixed in advance to the relay portion, etc. as necessary, and to allow the pressurized fluid to flow through the other end connection portion side of the pipe joint device. In addition, the connecting end portion of the connected pipe member (pressure tube, pressure hose, etc.) having flexibility is detachably inserted and connected, and the connection end is connected by being pulled and locked at the insertion position (connection position). It is often configured so that the connected pipe member can be released and released and removed while it is in the connected state. Configuration of so-called one-touch detachable pipe joint device As for the one-touch detachable pipe joint device, it is well known that the present inventor, for example, Japanese Patent Laid-Open Nos. 8-277985, 9-68293, 9-96384, or 9-184588. As previously disclosed, various new apparatus configurations have already been proposed and implemented.

  Thus, in this type of one-touch detachable pipe joint device, since the working fluid to be handled is a pressurized fluid set to a relatively high pressure, the connected pipe constituting the flow path of the pressurized fluid The pipe joint device provided in each member and each important point must have an appropriate pressure resistance in consideration of safety. For this reason, with respect to the connected pipe member, the rigidity during use tends to increase due to the applied pressure-resistant structure and the pressure applied by the pressurized fluid flowing through the interior, and in particular, it is carried by the hand. In the case of manual pneumatic equipment to be used, for example, a manual pneumatic tool, it is necessary to move and make full use of it while holding it with a hand during use. Flexibility is required to make the moving operation follow quickly and satisfactorily.

Various vibrations and shocks associated with air pressure discharge and air discharge after operation are transmitted through the connected pipe member, and the transmitted vibrations and shocks are also propagated to the air compression source side through the pipe joint device. Each of these phenomena may cause various undesirable results not only to the pipe joint device itself but also to the air compression source side, the manual pneumatic equipment side, and the operator. there were.

  The adverse effects due to vibration, impact, etc. during use of the pipe joint device as described above are caused by a substantial vibration absorption mechanism or vibration buffer mechanism for the vibration, impact, etc. in the corresponding flow path of pressurized air, that is, pressurized fluid.

In the configuration of each of these drawings, the same reference numerals indicate the same or corresponding parts.

[First Embodiment]

FIG. 1A is a half-side view, and FIG. 1B is a longitudinal sectional view. 2 shows the mode of the coupling ring member used in the joint main body apparatus shown in FIG. 1, wherein FIG. 2 (a) is an overall perspective view and FIG. 2 (b) is a longitudinal sectional view.

1 and 2, the joint main body device 10 according to the first embodiment is
A mounting portion having a required structure, for example, a male thread 12 for screwing and coupling to a discharge port of a pressurized fluid, and a hexagonal head 13 for hanging a screwing operation spanner are provided on the outer peripheral surface of the mounting side of one end. In addition, the first retaining ring 15 is provided in a radially intermediate portion of the first coupling end surface 14 on the other end side, and has a required axial length, and is provided in the axially inner portion. A first main member 11 configured using an appropriate material having a relatively high rigidity, for example, a resin, a metal, or the like, through which one internal flow path 16 is formed;
A required outer peripheral surface shape for detachably connecting a required connecting / disengaging mechanism, for example, a connecting / disengaging mechanism comprising the one-touch detachable pipe coupling device 100 of FIG. Is formed with a connection introduction cam surface 33 and a connected portion 32 consisting of a mooring circumferential groove 34, and in the same manner as described above, at the radial intermediate portion of the second coupling end surface 35 on the other end side, An appropriate material having a relatively high rigidity, such as a resin, having a second retaining ring 36 that protrudes in the required length in the circumferential direction and has a second internal flow path 37 formed in the axial direction. A second main body member 31 made of a rigid material such as metal;
Between the first and second coupling end faces 14 and 35 of each of the first and second main members 11 and 31, here, the first and second retaining fixing rings 15 and 36 are included. As a member for connecting the first and second coupling end faces 14 and 35 together at a predetermined interval, one of the third ends of the first and second main body members 11 and 31 is one third. A third engagement groove 53 that receives and retains the first retaining ring 15 that protrudes circumferentially from the connection end surface 14 of the first main body member 11 is provided on the other end surface 52 of the first main body member 11. Similarly, a fourth occlusion groove 55 for receiving and holding the second retaining ring 36 that protrudes from the coupling end surface 35 of the second main body member 31 is provided in the fourth coupling end surface 54. A third internal flow having the same inner diameter corresponding to each of the first and second internal flow paths 16 and 37 is formed in each of the perforations. Relatively material rigid with the required vibration absorbing property is high is that 56 is formed, for example, the coupling ring member 51 constituted by a resin material,
Have each.

  Here, with respect to the first and second retaining fixing rings 15 and 36 projecting from the coupling end faces 14 and 35 of the first and second main members 11 and 31, the coupling ring member 51 is provided. In order to make the all-in-one coupling and holding through the inner wall more effective, it is preferable to form a plurality of circumferential retaining projections 15a, 36a, etc. for fixing on both the inner and outer circumferential surfaces. And also important. In order to make the bonding and holding more effective, it is also effective to apply and form an appropriate adhesive on the entire bonding surface as necessary, and to use an adhesive means together.

  Further, for the coupling ring member 51, a resin material having a relatively high rigidity after molding and capable of giving a required vibration absorbing property, for example, a selected resin such as polyurethane resin, polyester resin, polyether resin, polyvinyl chloride resin, etc. A material is used and formed into a required shape and structure by injection molding using a predetermined molding die. In this way, the resin-molded coupling ring member 51 has the same rigidity as the first and second main members 11 and 31 and has the necessary absorbability for vibration, impact, and the like. It can be achieved effectively.

  Therefore, according to the coupling ring member 51 having the above-described configuration, the third engagement groove 53 is formed on the retaining ring 15 of the first main member 11, and the retaining ring 36 of the second main member 31. In contrast, the fourth engagement groove 55 is closely and firmly press-fitted and held in engagement, and at the same time, the third coupling end surface 52 is formed against the first coupling end surface 14. The fourth coupling end face 54 is pressed and adhered to the second coupling end face 36, respectively, and the first and second internal flow paths 16 and 18 are also connected by the third internal flow path 56. It communicates with a series. That is, in this way, the first and second main members 11 and 31 are joined together through the mutual coupling ring member 51, and the respective retaining and fixing rings 15 and 36 and the respective bites are retained. It can be made strong and effective by the occlusion holding with the groove 53, 55, and finally, the intended toughness and vibration absorbing properties can be imparted to the joint main body device 10. .

  On the other hand, the first and second main members 11 and 31 can be joined together through the coupling ring member 51 without using the resin-molded coupling ring member 51 alone. This can also be easily performed by directly injection-molding the coupling ring member 51 between the main members 11 and 31. That is, the coupling end surfaces 52 and 54 of the first and second main members 11 and 31 and the retaining fixing rings 15 and 36 are opposed to each other at a predetermined interval with respect to a predetermined molding die. The resin material that has been melted can be injected and filled into a mold while being placed, and can be integrally bonded as desired by so-called inner resin molding. Also in this case, it is effective to use a bonding means according to the necessity.

  In addition, the form of each retaining fixing ring 15 and 36 for integrally coupling the first and second coupling end faces 14 and 35 is not necessarily limited to the configuration of the first embodiment. Rather, any coupling means and coupling structure may be employed as long as an integrated coupling having the required toughness can be obtained.

  Furthermore, in this 1st Embodiment, although the external thread 12 for carrying out the screwing coupling | bonding to the attachment object part with respect to the attachment side of the said 1st main body member 11 is formed, the structure aspect of an attachment object part For example, when the configuration of the mounting target portion is a mounting nipple with a male thread, it is natural that a female thread is formed on the cup-shaped inner peripheral surface corresponding to this aspect. It is.

  In the joint main body device 10 according to the first embodiment having the above-described configuration, the first and second main body members 11 and 31 are directly coupled by the coupling ring member 51 having the required hardness and vibration absorption, or adhesive bonding as necessary. Since the entire device is strongly integrated, the required pressure resistance and connection strength can be maintained, and there is an advantage that vibration, impact, etc. added during use can be effectively reduced. When applied to the manual pneumatic tool described above, the workability can be greatly improved.

[Modification of First Embodiment]
3 and 4 show a schematic configuration of a joint main body device to which a modification of the first embodiment is applied.

Needless to say, the combined use of the above-described adhesive is also effective in resin molding in this case. And, in this way, the mutual coupling of the first and second main members 11 and 31 by the coupling ring member 51b through the through holes 15b and 36b is different from the coupling according to the configuration of the first embodiment.
