Description
Technical field
The present invention relates to a kind of 3D printer, and in particular to the accessory mounting structure on a kind of 3D printer.
Background technology
In existing 3D printer field, the accessory such as 3D printing shower nozzle used is generally multiple screwed metal assemblies
It is threaded together successively according to certain order, installs and dismounting is required for using the instruments such as spanner screwdriver.
But 3D printer works long hours at high temperature, the mounting structure screw thread of interior fittings and accessory is tighter, this
In the case of carry out accessory installation and removal be extremely easily damaged, so needing a kind of convenient, quick, safe match somebody with somebody in a hurry
Part mounts and dismounts device, to solve this problem present in prior art.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of 3D printer replacing
Accessory fast-connecting type structure, it is possible to achieve 3D printing accessory is convenient, quick, secure attachment installation and removal.
Technical scheme：In order to solve the above technical problems, the 3D printer that provides of the present invention is with interchangeable assembly parts fast-connecting type knot
Structure, including main body rack, the main body rack are provided with least one mounting groove；Each mounting groove, which is correspondingly provided with one, to be used for
The snap lock device of standing finish, the snap lock device includes spring clip and backboard, and the spring clip includes mirror image pair
Claim the first jig arm and the second jig arm set, first jig arm, backboard and the second jig arm order are enclosed and be connected into U-clamp mouthful；
The each snap lock dress of correspondence on perforation, the main body rack is arranged with first jig arm and the second jig arm
Put to be arranged with and be enclosed within the corresponding boss of the perforation, the snap lock device by the perforation on spring clip on boss,
And rotatable centered on boss be connected on main body rack；
The clamping boss for clamping accessory, institute are arranged with first jig arm inner surface relative with the second jig arm
When stating snap lock device and rotating to the angle of clamp position, the slotted eye of its corresponding mounting groove docks structure with the U-shaped jaws
Into the accommodating cavity of accommodating accessory.
It is preferred that, the backboard is provided with the handle that stretches out, the extension line of the handle and the extension line of backboard it
Between angle be not equal to 0.Further, it is cased with collet on the handle.Under this preferred scheme, the handle is easy to peace
Assembly and disassembly are unloaded, and the comfortableness and security of operation can be improved when being cased with collet.
It is preferred that, the boss is cylinder or truncated cone-shaped or polygon cylinder, and the perforation is circle corresponding with boss
Cylindricality or truncated cone-shaped or polygonal column cavity；The clamping boss is hemispherical.Under this preferred scheme, hemispherical clamping
Boss is used for the accessory that limiting locking carries corresponding hemispherical groove, is conducive to, when snap lock device rotates, being adjacent to institute
In the outer surface of installation fitting, and the corresponding hemispherical groove being smoothly included on institute's installation fitting, to lock and open
Process more smooth.
As it is further preferred that being arranged with first jig arm inner surface relative with the second jig arm more than two
Clamping boss.Under this preferred scheme, the limiting locking that snap lock device can be consolidated more is located at matching somebody with somebody in mounting groove
Part.
It is preferred that, it is arranged with breach on the edge of first jig arm and the second jig arm.Under this preferred scheme, card
Button locking device is not only caught in the groove on accessory come limiting locking accessory by clamping boss, can also be additionally by accessory
The anti-clamping boss being correspondingly provided with is caught in the breach on spring clip to realize that double limitation is locked, in this double limitation locking
On the basis of, the first jig arm and the spacing holding accessory of the second jig arm realize the mutual of accessory and snap lock device and spacing are engaged
Held tightly with locking.Under this scheme still further preferably, the perforation in first jig arm and the second jig arm sets with clamping boss
Put in the both sides of the breach.When being so conducive to the snap lock device to be rotated by the center of circle of boss, obtain one it is larger can
Radius of turn；And after snap lock device is rotated by the center of circle of boss to certain position, be caught in by clamping boss on accessory
Limiting locking accessory in corresponding groove, distance is longer between such clamping boss and perforation, can increase snap lock device pair
The clamping of accessory consolidates effect.This certain distance can flexible configuration as needed.
As it is further preferred that being arranged with more than two lack on the edge of first jig arm and the second jig arm
Mouthful.Under this preferred scheme, the limiting locking that snap lock device further can be consolidated more is located at the accessory in mounting groove.
Beneficial effect：The 3D printer that the present invention is provided with interchangeable assembly parts fast-connecting type structure, change in the past with spanner,
The instruments such as screwdriver by way of the threaded connections such as bolt and nut come interchangeable assembly parts such as installing/dismounting 3D printing shower nozzles, but
Interchangeable assembly parts are fixed on main body rack by snap lock device, it is convenient, quick, safe.The snap lock device
By the engaging of boss groove corresponding with accessory come limiting locking accessory, coordinate mounting seat and the firm effect of mounting groove,
And first the spacing holding of jig arm and the second jig arm act on so that interchangeable assembly parts are firmly mounted on main body rack.This
Invention further can be by multiple boss with respective slot engaging and breach form many with the engaging of corresponding clamping boss
Weight limiting locking, realizes the mutual of interchangeable assembly parts and snap lock device and spacing is engaged and locks holding.The invention enables
In 3D printing hot operation, dismounting, installation and the connection rapid and convenient of interchangeable assembly parts, in connection installation and unloading process no longer
Need to use the instruments such as spanner, screwdriver, tight, installing/dismounting rapid wear is become after also effectively prevent original threaded connection high-temperature heating
The problem of.Generally speaking, ease for use, security and steadiness are improved.
