The other end of decoupling rod 131 is connected with the lower end of printer body 110, i.e. the two ends of the first spring 136 bear against sleeve 133
Blind end 134 and decoupling rod 131 the one end away from printer body 110, one end of decoupling rod 131 is connected to printer sheet
One end of the end away from sleeve 133 of the lower end of body 110, the other end and the first spring 136 against.
When 3D printing is carried out using printer body 110, printer body 110 shakes, the court of decoupling rod 131
Moved to the direction of blind end 134 of sleeve 133, the first spring 136 is formed and is extruded, shrink the first spring 136, meanwhile, the
One spring 136 forms rightabout elastic force to decoupling rod 131, plays the effect of damping, imitates the printing of printer body 110
Fruit is more preferably.
It is preferably provided with：Decoupling rod 131 is coaxially disposed with sleeve 133, reduces rubbing between decoupling rod 131 and sleeve 133
Wipe power, it is to avoid the waste of the energy, while reducing the frictional dissipation between decoupling rod 131 and sleeve 133, extend its service life.
Please continue to refer to Fig. 2 and Fig. 3, in the present embodiment, second spring 137 is sheathed on outside sleeve 133, and sleeve 133 is set
In in a groove 141, and one end of second spring 137 is arranged in groove 141 and with the bottom wall of groove 141 against another
End and the lower end of printer body 110 against, i.e., the two ends of second spring 137 respectively with the bottom wall and printer sheet of groove 141
The lower end of body 110 against.When 3D printing is carried out using printer body 110, printer body 110 shakes, and subtracts
Shake bar 131 is moved towards the direction of blind end 134 of sleeve 133, second spring 137 is formed and is extruded, and receives second spring 137
Contracting, meanwhile, the first spring 136 forms rightabout elastic force to printer body 110, plays the effect of damping, makes printer
The printing effect of body 110 more preferably, and extends the service life of the damping device 120 of 3D printer.
In the damping device 120 of 3D printer, the installation of the first spring 136 and second spring 137 makes two springs same
Shi Jinhang cushioning effects, the elastic force that its every spring bears reduces, and spring is not likely to produce fatigue, after long-time use according to
So there is elasticity well, spring is not easy to be broken, and makes the printing effect of printer body 110 more preferable.
Please continue to refer to Fig. 3, in the present embodiment, spacer 151 is arranged with outside one end away from groove 141 of sleeve 133, the
Two springs 137 include first paragraph spring 138 and second segment spring 139, and first paragraph spring 138 is sheathed on outside sleeve 133, first paragraph
The two ends of spring 138 respectively with the bottom wall and spacer 151 of groove 141 against, second segment spring 139 is sheathed on outside decoupling rod 131,
The two ends of second segment spring 139 respectively with the lower end of spacer 151 and printer body 110 against.
Printer body 110 load it is relatively low in the case of, printer body 110 shake when, decoupling rod 131 is to sleeve
133 direction of blind end 134 motion, its motion amplitude is smaller, is mainly worked by the spring 136 of second segment spring 139 and first, right
Printer body 110 forms preferable cushioning effect, and damping is carried out to printer body 110.Printer body 110 load compared with
In the case of height, when printer body 110 shakes, decoupling rod 131 is moved to the direction of blind end 134 of sleeve 133, its motion width
Degree is larger, and the spring 136 of second segment spring 139 and first works, and first paragraph spring 138 starts to cooperate, it is ensured that printer
The good printing effect of body 110, by first paragraph spring 138, the collaborative work of the spring 136 of second segment spring 139 and first, greatly
The big fatigue strength for reducing spring, preferable cushioning effect is formed to printer body 110, and printer body 110 is carried out
Damping, meanwhile, extend the service life of the damping device 120 of 3D printer.
Please continue to refer to Fig. 3, in the present embodiment, sleeve 133 is outer to be also arranged with clamp nut 152, clamp nut 152 with every
Set 151 against.Fastening nut is formed to spacer 151 and limited mainly for being fixed to spacer 151.Outside sleeve 133
Spacer 151 can be adjusted according to its actual conditions, so as to adjust the length of second spring 137, make subtracting for 3D printer
Shake device 120 has good practicality, manufacturing cost reduction.
Please continue to refer to Fig. 3, in the present embodiment, first paragraph spring 138 is identical with the length of second segment spring 139, makes it
Stress facilitates the installation of first paragraph spring 138 and second segment spring 139 than more uniform.The pitch of first paragraph spring 138 is less than the
Two sections of pitch of spring 139, then the elastic force of first paragraph spring 138 is larger, and the elastic force of second segment spring 139 is smaller, first second segment
Spring 139 is operated, and being readily formed cushioning effect to the printer body 110 compared with low-load carries out damping, higher negative
When the printer body 110 of load is moved, first paragraph spring 138 can form stronger cushioning effect to printer body 110,
The scope for using it is wider, disclosure satisfy that the demand of the different use state of printer body 110.
In the present embodiment, damper 130 is four, and four grooves 141, each damper are provided with damping base 140
130 sleeve 133 is arranged in a groove 141, four one end of the decoupling rod of damper 130 131 respectively with printer sheet
Four corners connection of the lower end of body 110, four grooves 141 are arranged at four corners of damping base 140.Make damper 130
Damping effect to printer body 110 is more uniform, and the printing effect of printer body 110 is more preferable.
Similar implementation method can also be：Damper 130 is three, and three grooves are provided with damping base 140
141, the sleeve 133 of each damper 130 is arranged in a groove 141.Three dampers 130 form triangular structure,
Damper 130 can be made more uniform to the damping effect of printer body 110, the printing effect of printer body 110 is more preferable.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
