Fig. 8 represents about the ideograph in conjunction with the power relation of the locking of the fastening of accessory and releasing.F1 is the pulling force by the pressurization generation of water band.F2 is the power by the component generation of F1.This power makes pawl move towards the direction of central shaft X2, that is, this power plays a role not remove fastening.The power of F4 for being subject to from throw-out collar 22.In addition, F3 is the component of F4, and it plays a role to remove fastening.When equating with F2, F3 keeps balance.If establish α and be the fastening locking with the inclined-plane 23b of the groove 23c angle with respect to the central axis X 2 of inserting accessory 20, then the angle [alpha] of inclined-plane 23b can be processed to 0 °~90 ° arbitrarily angled.In addition, be that the angle with respect to the central axis X 2 of inserting fitment body 21 with inclined-plane 17a is removed in fastening if establish β, then the fastening releasing is certain with the angle beta of inclined-plane 17a.Here, the power of pawl by F2 accompanies therewith moving radially the distance of L2, overcomes the power of F1, and ring-type teat 23 is moving axially the distance of L1.At this moment, as the acting amount, become F1 * L1=F2 * L2.In addition, because L1/L2=tan (90-α), therefore, the relation of each power and angle is as follows.
F2/F1=tan (90-α) ... formula (1)
F4/F3=tan β ... formula (2)
Equally, F3=F2tan β=a (constant), therefore,
F4=aF1tan (90-α) ... formula (3)
Such suc as formula (3), by changing the angle [alpha] of inclined-plane 23b, make the size variation of the releasing power under the certain pressure F1.In the past do not lock the groove of usefulness in conjunction with accessory, so α is 90 °.Therefore, tan (90-α)=0, F4=0.That is, according to structure in the past, even under the state that has applied pressure, if existence then can be removed combination for the power of the surface friction drag of the power that overcomes latch spring 15 and fastening face.
On the other hand, if α is 0 °, then tan (90-α) becomes infinity, and irrelevant with the interior pressure of water band, the needed power F4 of the releasing of fastening becomes infinity.Like this, if suitably set the angle [alpha] of inclined-plane 23b, then the releasing power corresponding with it is determined.If the releasing power in conjunction with accessory (comprising latch spring power and frictional force) under the minimum radiation pressure is set greatlyr than the power of people's finger, even then there is misoperation, also can avoid accidentally being disengaged in conjunction with accessory.In addition, when the water band moved under pressurized state, even be hooked in obstacle, the combination of accessory can not thrown off simply yet.
In addition, only by above-mentioned countermeasure, under the not pressurized state of water band, can not utilize the pressure of water band to locking in conjunction with accessory, therefore, can not prevent from movement, causing throwing off in conjunction with accessory because of obstacle.Therefore, at the two ends that the inner peripheral surface of using cylindrical part 22a is removed in the fastening of throw-out collar 22, the throw-out collar side anti-slip tank 22c that processing is formed by fine groove.Outer circumferential face in the sliding cylinder section 25 that inserts fitment body 21 forms the main body side anti-slip tank 25a that is formed by fine groove.
In the occasion of people to removing in conjunction with accessory, bimanual finger promotes the flange shape operation unit 22b of throw-out collar 22 equably.Relative therewith, be hooked in the occasion of obstacle at the flange shape operation unit 22b of throw-out collar 22, side's side of flange shape operation unit 22b is stressed.Owing to remove the very little gap of existence between the interior week of using cylindrical part 22a and the periphery of the inserting fitment body 21 in the fastening of throw-out collar 22, therefore, if become a side stress, then as shown in Figure 5, fastening is removed with a side of the front end of cylindrical part 22a and is floated, and the opposing party nips and inserts the periphery of fitment body 21.In addition, same phenomenon also occurs with the rear portion of cylindrical part 22a in the fastening releasing.Therefore, by forming main body side anti-slip tank 25a, can make fastening remove the end face fastening of using cylindrical part 22a, but by remove the two ends formation throw-out collar side anti-slip tank 22c with the inner peripheral surface of cylindrical part 22a in fastening, can carry out more reliably mutual fastening, the power that puts on a side obstacle produces anti-skidding effect.Therefore, can prevent the careless disengagement in conjunction with accessory that causes because of obstacle.
Fig. 9 represents the measured value in conjunction with the releasing power of accessory in conjunction with accessory and present embodiment with respect in the past.
In order to confirm serviceability of the present invention, trial-production have 45 ° the fastening locking with the angle [alpha] of the inclined-plane 23b of groove 23c in conjunction with accessory, water band pressure changed and measure releasing power.In addition, for relatively, also measure the releasing power in conjunction with accessory in the past.Here, releasing power refers to inserting accessory 20 and accepting under the state that accessory 10 combines, in order to remove the maximum value of the power on the flange shape operation unit 22b that is applied to throw-out collar 22 in conjunction with the fastening of accessory.The measured load of the releasing power of the necessity here is the aggregate value of the power, frictional force of latch spring 15 and the latching force that produced by the interlock on inclined-plane.
As shown in Figure 9, under not to the stressed state of water band application, product in the past equates with the releasing power of present embodiment.On the other hand, under the pressurized state of water band, along with this pressure increases, needed power is removed in the combination of accessory to be increased.Under the 0.3MPa of common minimum working pressure, the releasing power of present embodiment is about 6 times of in the past product.
Maximum when expression is removed fastening in conjunction with accessory by the people in Figure 10 refers to the measured load of power.
