Embodiment
As shown in figure 1, the coupler structure that the present invention proposes, including：Shaft coupling 1 and axle 2.
As shown in Fig. 2 to 5, shaft coupling 1 is made up of mounting cylinder 11 and two sleeves 12, the bosom position of mounting cylinder 11
Provided with a circle convex portion, two sleeves 12 are separately fixed in the both ends of mounting cylinder 11, towards inside mounting cylinder 11 on sleeve 12
One end is inner, towards other end mounting cylinder 11 outside is outer end, the inners of two sleeves 12 is connected on convex portion, outer end and
The outer face of mounting cylinder 11 is concordant.Mounting cylinder 11 is made using yielding rubber, and sleeve 12 is made using metal, mounting cylinder 11 and set
Then cylinder 12 is adhesively fixed in mounting cylinder 11 by fastening glue by injection molded and is made of one structure again, yielding rubber
It is corrosion-resistant, damping effect is good.
As shown in Fig. 2 to 5, the inwall of sleeve 12 is provided with least one internal thread 121, preferably on the inwall of sleeve 12
It is evenly distributed with a plurality of internal thread 121.As shown in fig. 6, one end of axle 2 is installation end 21, installation end 21 is provided with and internal thread
The a plurality of external screw thread 211 of 121 quantity identicals, external screw thread 211 match one by one with internal thread 121, and installation end 21 revolves along internal thread 121
Turn in insertion sleeve 12, assembled using axle 2 from gravity, without instrument.Preferably, the inwall of sleeve 12 is diametrically along peace
To the taper gradually increased outside mounting cylinder 11, the shape of installation end 21 and the inner wall shape phase of sleeve 12 inside fitted tube 11
Match somebody with somebody, facilitate axle 2 to be slipped into from the outer end inboard end of sleeve 12.Further, the tooth of internal thread 121 it is wide along inside mounting cylinder 11 to peace
The gradually increase of the outside of fitted tube 11, during 21 initial rotation of installation end, the wide less one end of the tooth of external screw thread 211 screws in the tooth of internal thread 121
Wide larger one end, rotary resistance is small, and installation end 21 can rotate in axle 2 under gravity along 121 quick inboard end of internal thread, with
When installation end 21 and gradually going to the inner of sleeve 12, internal thread 121 and external screw thread 211 coordinate it is increasingly closer, until nothing
Method is rotated further, the screw-threaded coupling of installation end 21 and sleeve 12, and the axially position of installation end 21 is stable.
It is more excellent, as shown in Figure 7,8, the outer face of sleeve 12 be provided with the quantity identical of internal thread 121 fluting 122,
Each internal thread 121 is equipped with a fluting 122, and fluting 122 connects with the outer end of internal thread 121, and penetrates to sleeve 12
On wall, external screw thread 211 is screwed in internal thread 121 at fluting 122.As shown in fig. 6, the outer wall of installation end 21 is provided with and outer spiral shell
The quantity identical boss 212 of line 211, each external screw thread 211 are equipped with a boss 212, the inner phase of boss 212 and external screw thread 211
Connect, and slipped into the rotation of external screw thread 211 in corresponding fluting 122.Fluting 122 is led provided with one with what the edge of internal thread 121 was connected
To side 123, directed side 123 is in towards the inclined-plane of the outer inclination of mounting cylinder 11, and the gradient on inclined-plane and internal thread 121 1
Cause, boss 212 is slipped into fluting 122 along inclined-plane.The spacing side that an one end of tattooing handle 212 is rotated further is additionally provided with fluting 122
124, spacing side 124 is perpendicular to the outer face of sleeve 12, when boss 212 touches the bottom surface 125 of fluting 122, boss 212
One side abuts with spacing side 124, so as to reach the purpose of locating shaft.Axle 2 need to only be rotated in the reverse direction during dismounting, boss
212 spin up along inclined-plane, until axle 2 is completely drawn out.
As shown in Fig. 1,9, in preferred embodiment, internal thread 121 and external screw thread 211 use right-handed thread, shaft coupling 1
After the completion of the axle 2 at both ends is respectively mounted, the axle 2 of left end turns clockwise under motor effect, due to the axle 2 and shaft coupling 1 of left end
Matching relationship, under boss and screw thread collective effect, the axle of left end can drive shaft coupling 1 to rotate clockwise.For right-hand member
Axle, shaft coupling 1, which rotates, drives the axle of right-hand member to rotate, and the rotation direction of shaft coupling 1 is with hand of spiral on the contrary, suitable equivalent to the axle of right-hand member
Internal thread 121 and screw in fastening, make the assembling between the axle of right-hand member and shaft coupling 1 more firm, rotate faster, two Hes of axle 2
Assembling between shaft coupling 1 more fastens, and realizes self-locking effect.During dismounting, installation end 21 screws out sleeve 12 along counterclockwise again.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
