The replaceable assembly parts fast connecting structure comprises a main body bracket; at least one mounting slot is formed in the main body bracket; each mounting slot is correspondingly provided with a buckle locking device for fixing the assembly parts. The buckle locking device locks a sprayer by the blocking of a groove and a boss, and in match with the stabilizing function of a mounting seat and the mounting slot, and the limiting clamping function of a first clamp arm and a second clamp arm, the replaceable assembly parts are arranged on the main body bracket stably. Multiple limits and locks can further be formed by the blocking of a plurality of bosses and corresponding grooves and the blocking of gaps and corresponding blocking bosses, so that the mutual limiting, engaging, locking and clamping of the replaceable assembly parts and the buckle locking device are realized. The connecting, mounting and demounting are fast and convenient, the tools like spanner and screw driver are not required, the problem that the connecting, mounting and demounting are likely to be damaged due to the fact that the threaded connection in the prior art tightens in high temperature, and the practicality, safety and stability are improved.
Description
Technical field
The present invention relates to a kind of 3D printer, be specifically related to the accessory mounting structure on a kind of 3D printer.
Background technology
In existing 3D printer field, the accessories such as 3D printing head used are generally multiple screwed metal assembly according to a definite sequence and are screwed in successively together, install and dismounting all needs to use the instruments such as spanner screwdriver.
But 3D printer at high temperature works long hours, the mounting structure screw thread of interior fittings and accessory is tighter, in this case the installation and removal carrying out accessory be extremely hold flimsy, need a kind of convenient, quick, safe accessory installation and removal device so eager, solve this problem existed in prior art.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of 3D printer replacing accessory fast-connecting type structure, can realize 3D and print convenient, quick, safe being connected and installed and dismantling of accessory.
Technical scheme: for solving the problems of the technologies described above, 3D printer replacing accessory fast-connecting type structure provided by the invention, comprise main body rack, described main body rack is provided with at least one mounting groove; The equal correspondence of each mounting groove is provided with a snap lock device for standing finish, described snap lock device comprises spring clip and backboard, 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, on described main body rack, corresponding each snap lock device 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 clamping boss for clamping accessory, when described snap lock device rotates the angle to clamp position, the slotted eye of the mounting groove of its correspondence docks with described U-shaped jaws the accommodating cavity forming accommodating accessory.
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 clamping boss is hemispherical.Under this preferred version, hemispherical clamping boss is used for the accessory of limiting locking with the hemispherical groove of correspondence, be conducive to when snap lock device rotates, be adjacent to the outer surface of institute's installation fitting, and smoothly put under in the hemispherical groove of the correspondence on institute's installation fitting, to make locking and opening procedure more smooth.
As preferred further, the inner surface that described first jig arm is relative with the second jig arm is arranged with clamping boss more than two.Under this preferred version, snap lock device can be arranged in the accessory of mounting groove by more firm limiting locking.
Preferably, the edge of described first jig arm and the second jig arm is arranged with breach.Under this preferred version, snap lock device does not snap in by means of only clamping boss in the groove on accessory and carrys out limiting locking accessory, also can snap in additionally by the anti-clamping boss be provided with corresponding on accessory in the breach on spring clip and realize double limitation locking, on the basis of this double limitation locking, first jig arm and the second jig arm is spacing holds accessory tightly, what achieve accessory and snap lock device mutual to be spacingly engaged and locking is held tightly.Further preferred again under this scheme, the perforation in described first jig arm and the second jig arm and clamping boss are arranged on the both sides of 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, limiting locking accessory in groove corresponding on accessory is snapped in by clamping boss, such clamping boss is longer with the spacing of perforation, can increase the firm effect of the clamping of snap lock device to accessory.Certainly this distance can flexible configuration as required.
As preferred further, the edge of described first jig arm and the second jig arm is arranged with breach more than two.Under this preferred version, the limiting locking that snap lock device can be more firm is further arranged in the accessory of mounting groove.
beneficial effect:3D printer replacing accessory fast-connecting type structure provided by the invention, change and carried out the replacing accessories such as installing/dismounting 3D printing head with the instrument such as spanner, screwdriver by the mode that bolt and nut etc. is threaded in the past, but by snap lock device, replacing accessory is fixed on main body rack, convenient, quick, safety.Described snap lock device carrys out limiting locking accessory by the engaging of the boss groove corresponding with on accessory, coordinate the firm effect of mount pad and mounting groove, and first jig arm and the spacing of the second jig arm hold effect tightly, replacing accessory is firmly arranged on main body rack.The present invention forms multiple limiting locking by the engaging of multiple boss and respective slot and breach with the engaging of corresponding clamping boss further, and what achieve replacing accessory and snap lock device mutual to be spacingly engaged and locking is held tightly.3D is the invention enables to print in hot operation, the dismounting of replacing accessory, installation and connection rapid and convenient, be connected and installed and no longer need in unloading process to use the instrument such as spanner, screwdriver, 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.
