Description
Technical field
The utility model relates to a kind of 3D printer, is specifically related to the ejecting device on a kind of 3D printer.
Background technology
In existing 3D printer field, 3D printing head used is generally multiple screwed metal assembly and is from top to bottom screwed in successively together, and installing and dismantling all needs to use the instruments such as spanner screwdriver.
But shower nozzle at high temperature works long hours, screw thread is comparatively tight, and carrying out dismounting is in this case extremely hold flimsy, so need one to dismantle mode easily in a hurry, solves this problem.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of 3D printer fast disassembly type ejecting device, can realize the convenient dismounting fast and safely of 3D printing head.
Technical scheme: for solving the problems of the technologies described above, the 3D printer fast disassembly type ejecting device that the utility model provides, comprise main body rack, described main body rack is provided with at least one mounting groove; Also comprise at least one shower nozzle, described shower nozzle is provided with the mount pad corresponding with mounting groove, after the mount pad of described shower nozzle inserts one of them mounting groove, is fixed on main body rack by snap lock device.
Preferably, this device comprises two shower nozzles and two snap lock devices, and described main body rack is provided with two mounting grooves.
As preferred scheme, described snap lock device comprises spring clip and backboard, and described spring clip comprises the first jig arm and second jig arm of specular setting, and described first jig arm, backboard and the second jig arm order is enclosed and is connected into U-shaped jaws;
Described first jig arm and the second jig arm are arranged with perforation, described main body rack is arranged with and described corresponding boss of boring a hole, described snap lock device is enclosed within boss by the perforation on spring clip, and rotatablely centered by boss is connected on main body rack;
The inner surface that described first jig arm is relative with the second jig arm is arranged with the first clamping boss, described shower nozzle is arranged with and clamps groove corresponding to boss with described first, described snap lock device is that the center of circle rotates with boss, and snaps in shower nozzle described in limiting locking in groove by the first clamping boss on its spring clip.
Preferably, described backboard is provided with outward extending handle, and the angle between the extension line of described handle and the extension line of backboard is not equal to 0.Further, on described handle, cover has collet.Under this preferred version, described handle is convenient to installing/dismounting, and cover has the comfortableness and security that can improve operation during collet.
Preferably, described boss is cylindrical or truncated cone-shaped or polygon cylinder, and described perforation is the cylindrical or truncated cone-shaped corresponding with boss or polygonal column cavity; Described first clamping boss is hemispherical, and described groove is clamp hemispherical groove corresponding to boss with first.Under this preferred version, being designed with of hemispherical boss and hemispherical groove is beneficial to snap lock device when rotating, hemispheric first clamping boss is adjacent to the outer surface of shower nozzle, and smoothly puts under in the hemispherical groove on shower nozzle, locking and opening procedure more smooth.
As further preferred, the inner surface that described first jig arm is relative with the second jig arm is arranged with the first clamping boss more than two, described shower nozzle is arranged with and more than two clamps groove corresponding to boss with described first.Under this preferred version, snap lock device can be arranged in the shower nozzle of mounting groove by more firm limiting locking.
As further preferred version, the edge of described first jig arm and the second jig arm is arranged with breach, described shower nozzle is arranged with corresponding with described breach second and clamps boss, described snap lock device is that the center of circle rotates with boss, snap in corresponding breach by described second clamping boss, first clamping boss snaps in groove simultaneously, carrys out shower nozzle described in limiting locking.Under this preferred version, snap lock device does not snap in groove by means of only the first clamping boss and carrys out the shower nozzle that limiting locking is arranged in mounting groove, also snap in breach corresponding on spring clip additionally by the second clamping boss on shower nozzle and realize double limitation locking, on the basis of this double limiting locking, first jig arm and the second jig arm is spacing holds shower nozzle tightly, what achieve shower nozzle and snap lock device mutual to be spacingly engaged and locking is held tightly.Further preferred again under this scheme: the perforation and first in described first jig arm and the second jig arm clamps the both sides that boss is arranged on described breach.Being conducive to snap lock device like this take boss as center of circle when rotating, and obtains a larger rotatable radius; And when snap lock device is that the center of circle rotates to certain position with boss, snapping in limiting locking shower nozzle in groove by the first clamping boss, such first clamping boss is longer with the spacing of perforation, can increase the firm effect of the clamping of snap lock device to shower nozzle.Certainly this distance can flexible configuration as required.
As the further preferred version that above-mentioned further preferred version is heavy, the edge of described first jig arm and the second jig arm is arranged with breach more than two, described shower nozzle is arranged with more than two, corresponding with described breach second and clamps boss.Under this preferred version, the limiting locking that snap lock device can be more firm is further arranged in the shower nozzle of mounting groove.
Preferably, the cross section of described second clamping boss be circular or square or polygon or the shape of a hoof, and described breach is the breach that the second clamping boss can be made smoothly to snap in and skid off when snap lock device take boss as center of circle rotation.
beneficial effect:the 3D printer fast disassembly type ejecting device that the utility model provides, change the mode that in the past must be threaded by bolt and nut etc. with the instrument such as spanner, screwdriver, but by snap lock device, 3D printing head is fixed on main body rack, convenient, quick, safety.Described snap lock device carrys out limiting locking shower nozzle by groove with the engaging of boss; Coordinate the firm effect of mount pad and mounting groove, and the first jig arm and the spacing of the second jig arm hold effect tightly, and 3D printing head is firmly arranged on main body rack.The utility model forms multiple limiting locking by the engaging of multiple tracks groove and boss and breach with the engaging of clamping boss further, and what achieve shower nozzle and snap lock device mutual to be spacingly engaged and locking is held tightly.The technical scheme that the utility model provides makes installation, the dismounting rapid and convenient of 3D printing head, especially time in hot operation state, install and no longer need to use the instrument such as spanner, screwdriver in unloading process, after also effectively prevent original high-temperature heating that is threaded, becoming problem that is tight, installing/dismounting rapid wear.Generally speaking ease for use, security and steadiness is improved.
