Fig. 3 is the three-dimensional exploded view of support member governor motion of the present utility model.As shown in Figure 3, fuselage 4 has one and is used for the underframe 41 that engages with support member 3, and underframe 41 has to the projecting inward arch portion 43 of fuselage 4, and this arch portion 43 has a through hole 45.Accordingly, support member 3 has an arch portion 33 that protrudes to fuselage 4 directions, and this arch portion 33 has a long and narrow through hole 31 of arranging along the bending direction of arch.The degree of crook of arch portion 33 and arch portion 43 is roughly suitable, shape matches, and can fitting tightly, and the extension angle of arch portion 33 is greater than the extension angle of arch portion 43, can allowing support member 3 to pivot, and fit tightly all the time with fuselage 4 around the relative fuselage 4 of self longitudinal axis.
A connector is specially an axle 5 with screw thread, passes the through hole 31 of aforesaid arch portion 33 and the through hole 45 of arch portion 43 successively, extends to the inside of fuselage 4.The form of connector can have multiple, as, have the axle of teeth groove, perhaps and support member 3 be combined as a whole etc.Axle 5 has less shaft-like main part 53 of diameter and the bigger end 55 of diameter.Also has a pad 51 between the arch portion 33 of end 55 and support member 3.A clamping element 7 is specially nut, and the inside and the axle that are positioned at fuselage 45 match, and the underframe 41 and the support member 3 of fuselage 4 is clamped between the end 55 of clamping element 7 and axle 5, and its clamping degree of tightness can be regulated.When clamping was loose, support member 3 can pivot with adjusting angle; When clamping was tight, support member 3 was fixed on a specific angle, and aforesaid long and narrow through hole 41 allows support member 3 can pivot in certain angular range when axle 5 passes.
The support member governor motion of first embodiment of the present utility model has the coarse adjustment of clamping tightness and two kinds of adjustment structures of fine tuning.Coarse adjustment structure and fine tuning structure are to operate by an independent regulating part, move simultaneously to reach a kind of quick and easy, the operating experience that settles at one go.The convenience of be describing, below the fine tuning structure of the clamping tightness of support member is described earlier.
As Fig. 3, a regulating part 8 is provided with in abutting connection with described clamping element 7, and regulating part 8 comprises an adjusting portion 81 and a spanner portion 83, and adjusting portion 81 is set on the nut 7, spanner portion 83 extends to fuselage 4 outsides, for the clamping tightness of operator's operation with the adjusting support member.Be provided with a cover clutch between regulating part 8 and the nut 7.Concrete, clutch comprises first clutch part 85 and second clutch part 72, first clutch part 85 is fixedly connected on the adjusting portion 81 of regulating part 8, first clutch part 85 has the axial end flank of tooth of annular, has end to end a plurality of end tooth on the end tooth face, each end tooth shape unanimity, have respectively two that the angle of inclination do not wait domatic, and each end tooth arbitrary domatic adjacent to the angle of inclination of adjacent end tooth do not wait domatic.Second clutch part 72 is fixedly connected on the clamping element 7, the annular section that formation is outwards extended along diametric(al) from the bottom of the main part of clamping element 7, this annular section has the axial end flank of tooth, relative and the shape of the longitudinal end flank of tooth of the longitudinal end flank of tooth of second clutch part 72 and first clutch part 85 matches, fitting tightly each other.The opposite side relative with annular section is provided with the groove 77 of a ring-type on the clamping element 7, and a collar 11 is installed on the groove 77, is equipped with packing ring 10 between collar 11 and the ring part successively, elastic component 9, the adjusting portion 81 of regulating part 8.Like this, elastic component 9 is specially a stage clip, oppresses first clutch part 85 and second clutch part 72 closely against each other.
The fine tuning structure that is provided with as above-mentioned mode has reached meticulous adjusting clamping element 7, and the effect of the clamping tightness of volitional check maximum.When operator's rotary spanner portion 83, the adjusting portion 81 and first clutch part 85 are followed rotation, by thereon the end tooth and the end tooth interlock of second clutch part 72, and then drive second clutch 72 and clamping element 7 is followed rotation.Because two longitudinal end flank of tooth are fit together by elastic component 9 compressings, keep the critical torque of fitting so have, the size of critical torque is by the inclined degree and the coefficient of friction acting in conjunction decision of the coefficient of elasticity of elastic component 9 and stressed end tooth.When the moment of torsion that bears during greater than critical torque, first clutch part 85 will go round and begin again along the inclined plane of end tooth with respect to 72 rotations of second clutch part and overcome and move on the pressure of elastic component 9 and then pressurized falls, promptly begin to climb repeatedly.Again because the inclination angle, inclined plane that end tooth rises along clockwise direction is not equal to the inclination angle that descends along clockwise direction, so degree of tightness regulating part 8 right handed critical torques are not equal to the critical torque of rotation counterclockwise.Definition degree of tightness regulating part 8 clockwise rotating to be are rotated in the forward, and it is close to each other to be rotated in the forward the end 55 that drives clamping element 7 and axle 5; Definition regulating part 8 is anticlockwise to rotate to be reverse rotation, and the end 55 that reverse rotation drives clamping element 7 and axle 5 away from each other.In the present embodiment, the critical torque that setting is rotated in the forward is less than the critical torque of reverse rotation, and, the critical torque that is rotated in the forward is the default critical torque of clutch of the present utility model, the default critical torque of this clutch set corresponding to corresponding to default support member clamping tightness, promptly, when the elasticity of support member 3 and underframe 4 during less than a default support member clamping tightness, the operator can operate spanner portion 83 and be rotated in the forward, clamping element 7 is near the bottom 55 of axle 5, the clamping tightness is increased, up to reaching default support member clamping tightness, after this order about the required moment of torsion of clamping element 7 rotations once more greater than the critical torque that is rotated in the forward, the foregoing climbing of first clutch part, 85 beginnings no longer drives clamping element 7 rotations.Because the critical torque of reverse rotation is greater than the critical torque that is rotated in the forward, after reaching the maximum grip tightness, the operator can drive 83 reverse rotations of spanner portion, unclamps support member 3.In the present embodiment, clamping element 7 is motion on the clamping direction in the motion on the axial direction of axle 5, and it causes support member clamped.
The key point that it may be noted that the support member clamping tightness of realizing that restriction is default is a clutch is set between degree of tightness regulating part 8 and clamping element 7, and that the specific embodiment of clutch can have is multiple.As, this programme is provided with axial end tooth, however it also is attainable on the side face that axle 5 and clamping element 7 cooperate end tooth being set radially.For another example, the clutch of this programme cooperates by the end tooth face to be realized, yet the clutch that steel ball cooperates with chute also is attainable.The average personnel in this area design easily and are different from the clutch of scheme as previously mentioned.
The coarse adjustment structure of the clamping tightness of support member 6 is described below.
As Fig. 3, the coarse adjustment structure comprises one with respect to the movable moving cam 73 of fuselage, also comprises a quiet cam 6 static with respect to fuselage.Moving cam 73 is fixedly connected on the clamping element 7, rotates along with the rotation of clamping element 7.High plane and low plane on moving cam 73 has axially.Quiet cam 6 is arranged in the groove in the fuselage 4, high plane and low plane on having axially, and the high plane of shape and moving cam 73 and low plane match so that each contented high-order face during in the face of the other side's low plane mutual gapless against.When clamping element 7 drives moving cams 73 rotations, the high plane of moving cam 73 is during in the face of the high plane of quiet cam 6, the clamping degree fast rise of support member 3.When clamping element 7 drives moving cams 73 rotations, the high plane of moving cam 73 is during in the face of the low plane of quiet cam 6, and the clamping degree of support member 3 descends fast.This be because the movable length variations between clamping element 7 and axle 5 the bottom 55 one section particular length, this segment length equals the high plane of moving cam 73 haply and the distance of low plane adds the high plane of quiet cam 6 and the distance of low plane, because the variable in distance that this moment, axle 5 rotations caused is less relatively.
Foregoing, the fine tuning structure and the coarse adjustment structure of support member 3 tightness are combinations.Loose at support member 3, the low plane separately of quiet cam 6 and moving cam 73 is in the face of the other side's high plane, when needing to clamp, the operator operates spanner portion 83 and is rotated in the forward, adjusting portion 81 at first drives nut 7 rotations by clutch, make the high plane of quiet cam 6 and moving cam 73 abut against each other, this moment, support member 3 was clamped fast, yet may also not reach default support member clamping tightness, the operator can operate spanner portion 83 and continued to be rotated in the forward this moment, up to reaching default support member clamping tightness, clutch begins climbing.Support member 3 clamps, and in the time of need unclamping, process is opposite with the process of clamping, the operator operates 83 reverse rotations of spanner portion, and nut 5 unclamps a segment distance, and the high plane of quiet then cam 6 and moving cam 73 is separated from each other, low plane separately is in the face of the other side's high plane, and support member 3 is released.
In the process that clamps repeatedly and unclamp of support member 3, the high plane of moving cam 73 and quiet cam 6 can produce wearing and tearing, the clamping effect that reaches by camming will reduce like this, yet much more slightly this can be rotated in the forward the wear extent that a segment distance compensates camming by spanner portion 83.This has prolonged the service life of support member regulating system.
Below in conjunction with Fig. 4, Fig. 5, Fig. 6 second embodiment of the present utility model is described.
Fig. 4 is the three-dimensional exploded view of second embodiment of the present utility model.As Fig. 4, second embodiment has same fuselage 4 and support member 3.Also have connector, be specially axle 50, pass the through hole on fuselage 4 and the support member 3, extend to support member 3 the bottom a and pass pad 51.After axle 50 assembles, be positioned at pad 51 times, the part in a of support member 3 bottoms is provided with the hole 501 perpendicular to the axial direction of axle 50, and bearing pin 590 passes hole 501, perpendicular to axle 50.Be socketed with regulating part 80 of the present utility model on the bearing pin 590, clamping element 70 and clutch therebetween.Be regulating part, clamping element and clutch therebetween all are contained in a of support member 3 bottoms.
Specifically describe the support member governor motion of second embodiment in conjunction with Fig. 4, Fig. 5, Fig. 6, a flat quadrate part 503 is formed at the bottom of axle 50, the end of bearing pin 590 is greater than the diameter in hole 501, be positioned at the right side of flat quadrate part 503, the axial region of bearing pin 590 passes the opposite side that hole 501 extends across flat quadrate part, its end is provided with draw-in groove and the collar 110 that matches, and with aforesaid regulating part 80, clamping element 70 and clutch therebetween are arranged at the left side of flat quadrate part 503.Be provided with packing ring 100 successively, spring 90, regulating part 80, clamping element 70 between the flat quadrate part 503 of collar 110 and axle 50.As figure, the same with the regulating part 8 of first embodiment, regulating part 80 comprises an adjusting portion 810 and a spanner portion 830.Adjusting portion 810 is suitable for the person's of being operated operation to regulate clamping element 70.Clamping element 70 is specially an eccentric wheel, and it has apart from its axis of rotation far-end far away and nearer near-end, and from the near-end to the far-end, eccentric radius gradually changes.Like this, during clamping element 70 rotation, if its far-end butt pad 51, then oppress support member 3 and fuselage 4 is close to each other with clamp supports, if its near-end butt pad 51 then unclamps support member 3 and fuselage 4, to unclamp support member 3.Similar first embodiment, be provided with clutch between clamping element 70 and the regulating part 80, be specially: adjusting portion 810 and clamping element 70 end face of butt joint mutually are the end tooth face 820 and the end tooth face 720 of interworking, and they have continuous fluctuating and the end to end a plurality of end teeth of ring-type separately.Spring 90 1 ends are resisted against on the packing ring 100, and an end is resisted against on the adjusting portion 810, and the pressure side flank of tooth 820 and end tooth face 720 are close to each other.Same, the clamp mechanism among second embodiment has default critical torque.
The mechanism of the support member governor motion of second embodiment as described below.When needs are regulated the angle of support member 3, spanner portion 830 is pulled around bearing pin 590 pivots from default clamped position, at this moment, because the end tooth face 820 of the spring 90 compressing adjusting portions 810 in the clutch and the end tooth face 720 of clamping element 70 are close to each other, regulating part 80 drives clamping element 70 and pivots around bearing pin 590, the far-end of clamping element 70 leaves pad 51 gradually, unclamps support member 3.After the angle that regulates support member 3, oppositely pull spanner portion 830, by the clutch effect, drive clamping element 70 and pivot, make its far-end near pad 51, clamp supports 3.Clamping degree at support member 3 reaches preset value, make the clutch effect, after driving the required default critical torque of moment of torsion of clamping element 70 further clampings greater than clutch, the moment of torsion that clutch no longer transmits regulating part 80 is to the clamping section 70, the climbing that the end tooth face 720 of the end tooth face 820 of the adjusting portion 810 that matches and clamping element 70 of being specially begins to go round and begin again, adjusting portion 810 overcomes the compressing of spring 90, clamping element 70 leaves in axial direction court along bearing pin 590, end tooth face 820 and 720 disengagings of end tooth face are meshing with each other, after crossing a lattice end tooth, end tooth face 820 and end tooth face 720 are engaged with each other under spring 90 compressings once more, so go round and begin again.Return to default clamped position up to spanner portion 830.In the present embodiment, the far-end that causes eccentric part of clamping element 70 is a clamping direction against the pivotal orientation of pad 51, and it causes support member 3 clamped.
As previously mentioned, in a second embodiment, the near-end of clamping element 70 gradually changes and rises to far-end, under initial state, clamping element 70 does not need the far-end of its radius maximum against pad 51, and certain position that only needs certain radius in the far-end promptly can reach clamping against pad 51, and then regulating part 80 and spanner portion 830 thereof reach default clamped position by the climbing action of clutch.Longer when service time, clamping element 70 wearing and tearing, after the position radius of original certain radius reduced in the far-end, regulating part 80 still drives clamping element 70 to be continued to rotate up to the new position with this certain radius against pad 51.Like this, the radius that has reached distal-most end up to the degree of wear of clamping element 70 is reduced to the degree of this certain radius, the support member governor motion still is operable, this has prolonged the service life of support member governor motion greatly, and, it is that clamping is reliable and stable through the optimal value of calculating and test draws (being the clamping degree of the predetermined torque correspondence of clutch) all the time that the support member of support member governor motion clamps degree.
In the utility model, in the process that clamps repeatedly and unclamp of support member 3, the operator only need operate independent spanner portion, just can reach support member 3 clampings that settle at one go and the effect of unclamping, simple and fast.
