Specific embodiment
As shown in Figure 1, the coupler structure that the utility model proposes, including：Shaft coupling 1 and axis 2.
As shown in Fig. 2 to 5, shaft coupling 1 is made of mounting cylinder 11 and two sleeves 12, the bosom position of mounting cylinder 11
Equipped with a circle protrusion, 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 end, towards the other end outside mounting cylinder 11 is outer end, the inner ends of two sleeves 12 is connected on protrusion, outer end with
The outer end face of mounting cylinder 11 is concordant.Mounting cylinder 11 is made of yielding rubber, and sleeve 12 is made of metal, mounting cylinder 11 and set
Then cylinder 12 is adhesively fixed in mounting cylinder 11 again by fastening glue by injection molded and is made of one structure, yielding rubber
It is corrosion-resistant, damping effect is good.
As shown in Fig. 2 to 5, the inner wall of sleeve 12 is equipped at least one internal thread 121, preferably on the inner wall of sleeve 12
It is evenly distributed with a plurality of internal thread 121.As shown in fig. 6, one end of axis 2 is installation end 21, installation end 21 is equipped with and internal thread
The identical a plurality of external screw thread 211 of 121 quantity, external screw thread 211 match one by one with internal thread 121, and installation end 21 is revolved along internal thread 121
Turn in insertion sleeve 12, assembled using axis 2 from gravity, without tool.Preferably, the inner wall of sleeve 12 is diametrically along peace
To the gradual increased taper in 11 outside of mounting cylinder, the shape of installation end 21 and the inner wall shape phase of sleeve 12 inside fitted tube 11
Match, axis 2 is facilitated to be slipped into from the outer end of sleeve 12 to inner end.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 smaller one end of 211 tooth of external screw thread screws in 121 tooth of internal thread
Wide larger one end, rotary resistance is small, installation end 21 can axis 2 under gravity along internal thread 121 quickly to inner ends thereof, with
When installation end 21 and gradually going to the inner end 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 21 axially position of installation end is stablized.
More preferably, as shown in Figure 7,8, the outer end face of sleeve 12 is equipped with the fluting 122 identical with 121 quantity of internal thread,
Each internal thread 121 is equipped with a fluting 122, and fluting 122 connects with the outer end of internal thread 121, and penetrates through to sleeve 12
On wall, external screw thread 211 is screwed at fluting 122 in internal thread 121.As shown in fig. 6, the outer wall of installation end 21 is equipped with and outer spiral shell
The identical boss 212 of 211 quantity of line, each external screw thread 211 are equipped with a boss 212, the inner end phase of boss 212 and external screw thread 211
It connects, and is slipped into corresponding fluting 122 with the rotation of external screw thread 211.Fluting 122 is led equipped with one with what 121 edge of internal thread was connect
To side 123, directed side 123 is in towards the inclined-plane of 11 outer inclination of mounting cylinder, and the gradient on inclined-plane and internal thread 121 1
It causes, boss 212 is slipped into along inclined-plane in fluting 122.The limiting side that an one end of tattooing handle 212 is rotated further is additionally provided on fluting 122
124, limit outer end face of the side 124 perpendicular to sleeve 12, when boss 212 touches the bottom surface 125 of fluting 122, boss 212
One side is abutted with limiting side 124, so as to achieve the purpose that locating shaft.Axis 2 need to only be rotated in the reverse direction during dismounting, boss
212 spin up along inclined-plane, until axis 2 is completely drawn out.
As shown in Fig. 1,9, in preferred embodiment, internal thread 121 and external screw thread 211 are using right-handed thread, shaft coupling 1
After the completion of the axis 2 at both ends is respectively mounted, the axis 2 of left end rotates clockwise under motor effect, due to the axis 2 of left end and shaft coupling 1
Matching relationship, under boss and screw thread collective effect, the axis of left end can drive shaft coupling 1 to rotate clockwise.For right end
Axis, the rotation of shaft coupling 1 drive the shaft rotation of right end to move, and 1 rotation direction of shaft coupling is with hand of spiral on the contrary, the axis for being equivalent to right end is suitable
It internal thread 121 and screws in fastening, make the assembling between the axis of right end and shaft coupling 1 more firm, rotate faster, two 2 Hes of axis
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 above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
