Abstract
A nozzle inversion-prevention structure comprises a nozzle radiator, a one-way clamping nut, and a Teflon tube, wherein the Teflon tube is mounted in the nozzle radiator and fixed by the one-way lock-position nut, the Teflon tube is higher than the one-way lock-position nut; a groove is arranged on the top of the nozzle radiator, and the one-way lock-position nut is arranged in the groove. The one-way lock-position nut replaces the existing set screw, so as to solve the problem that the Teflon tube is locked in the nozzle and not easily exchanged.
Description
Technical field
The utility model relates to fusion sediment technology 3D printer field, is specially the structure of the anti-inversion of a kind of nozzle.
Background technology
In existing structure, teflon pipe is withstood by the set screw of a perforate, and concordant with set screw ground, in the situation that nozzle has fault to change teflon pipe, the centre of teflon pipe in nozzle, two does not have impetus, clip less than, be difficult for to take out change.
Utility model content
The technical problem that the utility model solves is to provide the structure of the anti-inversion of a kind of nozzle, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A structure for the anti-inversion of nozzle, comprises nozzle radiating tube, unidirectional screens nut, teflon pipe; It is inner that described teflon pipe is contained in nozzle radiating tube, by unidirectional screens nut, fixes, and teflon pipe exceeds unidirectional screens nut; Described nozzle radiator top is fluted, and unidirectional screens nut is in groove.
Further, described unidirectional screens nut is provided with active button, presses active button, and unidirectional screens nut lost efficacy to the screens of teflon pipe.
Beneficial effect
The utility model utilizes unidirectional screens nut to substitute existing set screw, has solved teflon pipe and has been stuck in the middle of nozzle, not easily changeable problem.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the structure of the anti-inversion of a kind of nozzle, comprises nozzle radiating tube 1, unidirectional screens nut 2, teflon pipe 3; Described teflon pipe 3 is contained in nozzle radiating tube 1 inside, and fixing by unidirectional screens nut 2, teflon pipe 3 exceeds unidirectional screens nut 2; Described nozzle radiator 1 top is fluted, and unidirectional screens nut 2 is in groove.
Further, described unidirectional screens nut 2 is provided with active button, presses active button, and the screens of 2 pairs of teflon pipes 3 of unidirectional screens nut was lost efficacy.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
