Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is sectional perspective system decomposition figure of the present utility model.
Fig. 2 A~2F is the action sectional drawing that cam handle of the present utility model presses down.
Fig. 3 A~3B is the action sectional drawing that cam handle of the present utility model unlocks.
Fig. 4 is an enforcement illustration of the present utility model.
Fig. 5 is the partial exploded view of traditional rapid pipe joint.
As shown in Figure 1, the utility model also is to adopt the relative configurations that is same as existing rapid pipe joint, even also the upper and lower of joint body 10 forms respectively and can supply to insert loop bar 15 so that cam handle 20 articulates and be formed with the structures such as jack 12 of confession latch 54 insertions with it, and cam handle 20 also be by press down and on the mode of drawing operate but of the present utility model being characterised in that:
These cam handle 20 bottom surfaces are defined with two lateral plates 22 and are formed an inner space, form the side opening 23 that supplies the pivot column sleeve to go at two lateral plates, 22 front and back positions, 24, the also integrally formed all right one way or the other confession of the inner bottom surface of cam handle 20 is inserted in the cross section respectively and is font shell fragment 31,32 enter, and can be corresponding to this two shell fragment 31,32 belows are inserted in Y shape button piece 40 respectively and a plectrum 50 enters, and with individual other pivot post respectively through the side opening 23 of lateral plate 22,24 pass the perforation 41 of Y shape button piece 40 and plectrum 50,51 and make its location and be before and after the mutual state that abuts against of screens, and on these Y shape button piece 40 front ends, form long down respectively, galianconism 44,43, and form a V-arrangement catching groove 42 betwixt, the back segment of Y shape button piece 40 is a planar, and plectrum 50 front ends are for forming the inner end 52 of prominent shape, the rear end is a longitudinal bodies, and can pass the formed arc notch 25 in cam handle 20 rear ends, and the rearward end that this plectrum 50 exposes, so that follow-up stirred when desiring to unlock (appearance aftermentioned), in addition, be sheathed with draw ring commonly used 53 at these plectrum 50 ends, chain and latch 54 also remain with existing latch locking device.
Then be formed with aforementioned cam handle 20 inboard two corresponding projections 13 on joint body 10 and stretch through at the structures such as fastening bar 14 of 13 of two projections, this fastens bar 14 is to utilize relative configurations to fasten with it after confession cam handle 20 presses down and automatically lock.
On the manner of execution after the utility model combination, can cooperate referring to shown in Fig. 2 A~2F figure, earlier with Fig. 2 A, 2B in regular turn with cam handle 20 when pressing down, this Y shape button piece 40 and plectrum 50 are subjected to top shell fragment 31 respectively, 32 to the down spring effect, Y shape button piece 40 is towards left side, and plectrum 50 (is level in cam handle 20) for deflection clockwise abuts against its rear end on the stop block below the breach 25 of cam handle 20, in Fig. 2 B, because the galianconism 43 of Y shape button piece 40 front end lower positions just can be crossed the fastening bar 14 of joint body 10, so showing the front end catching groove 42 of this Y shape button piece 40 in Fig. 2 C moves in the fastening bar 14, and at Fig. 2 D, 2E, the continuing again of 2F makes under the state that cam handle 20 presses down, make in regular turn and fasten long-armed 44 of bar 14 pushing and pressing Y shape button pieces 40, and make it towards deflection clockwise, slip over the incline position of plectrum 50 front ends more simultaneously with the end of Y shape button piece 40, also make plectrum 50 be counterclockwise deflection (as Fig. 2 D) in the lump thereupon, after plectrum 50 front ends are crossed in the rear end of Y shape button piece 40 (as Fig. 2 E), can utilize the back stretch of the shell fragment 31 that is positioned at Y shape button piece 40 tops, and change into shown in Fig. 2 F, make Y shape button piece 40 change level into, this moment, the catching groove 42 of Y shape button piece 40 front ends just fastened with fastening bar 14, the planar surface portion of Y shape button piece 40 rear ends then is resisted against plectrum 50 preceding bottom positions, and because plectrum 50 rear ends are subjected to the backstop of cam handle 20 rear end breach 25 material below, so Y shape button piece 40 and plectrum 50 present the mutual clip of a level, just pining down mutually down at aforementioned every structure like this, give the anti-loose effect that cam handle 20 1 automatically locks, therefore, when pressing down in regular turn by aforementioned cam handle 20 at Fig. 2 A~2F, can form smooth-goingly and automatically lock, by contrast, a kind of lock in place effect that need not operation bidirectional promptly is provided, obviously easy and have more practical effect by the rapid pipe joint of inserting the latch mode than traditional need.
And desire is when removing above-mentioned automatically locking, more need not extra operating procedure, the draw ring 53 that draws cam handle 20 to be positioned at the rear on only needing can be finished, that is as shown in Figure 3A, when desiring to unlock, only need draw ring 53 to draw this plectrum 50 that is positioned at cam handle 20 ends on the hand or to link, so that being counterclockwise deflection, plectrum 50 breaks away from when the clip to Y shape button piece 40 ends, even also Y shape button piece 40 is free state, so only need the mode shown in Fig. 3 B, direct pull-up cam handle 20, and the galianconism 43 of Y shape button piece 40 is subjected to joint body 10 to fasten bars 14 to set aside and be counterclockwise deflection, galianconism 43 is moved apart fasten bar 14 positions, can take advantage of a situation unlocks cam handle 20 and returns to opening state shown in Fig. 2 A.
In addition, the aforementioned structure that 13 grafting of two projections fasten bar 14 that passes through that is positioned at joint body 10 more can be changed into as shown in Figure 4, and directly the clipping block 60 of likeness in form taper also can reach identical automatic fastening locking effect on joint body 10.
