[0033] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the present application will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict. In the following description, a lot of specific details are described in order to fully understand the present application, and the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0035] Example:
[0036] like Figures 1-4 As shown, this embodiment provides a detachable filament tray for storing 3D printing filament, including a first tray body 1, a second tray body 2 and a winding shaft 3, one end of which is connected to the first tray body 1;
[0037] The other end of the winding shaft 3 is provided with a connecting cavity 4. The inner wall surface of the connecting cavity 4 is provided with a first connecting thread 5 and a first limiting part. The first thread is arranged along the radial direction of the winding shaft 3.
[0038] The second disc body 2 is provided with a connecting boss 9, and the outer wall surface of the connecting boss 9 is provided with a second connecting thread 10 and a second limiting part. The second connecting thread 10 is arranged along the radial direction of the connecting boss 9.
[0039] During the process of the connecting boss 9 entering the connecting cavity 4 by rotation, the first connecting thread 5 and the second connecting thread 10 cooperate, and the first limiting part cooperates with the second limiting part.
[0040] The detachable tray of this embodiment can be assembled or disassembled between the first tray 1 and the second tray 2 by rotation, thereby forming a structure for storing 3D printing filament with the first tray 1, the second tray 2, and the winding shaft 3. Specifically, during the process of the connecting boss 9 entering the connecting cavity 4 by rotation, for example, when the second tray 2 is rotated clockwise, the first limiting part and the second limiting part cooperate. At this time, the first connecting thread 5 and the second connecting thread 10 cooperate and engage. At this time, the first tray 1 and the second tray 2 are connected through the mutual engagement of the threads, and at the same time, the first limiting part and the second limiting part engage. The mating parts of the first and second discs act as rotational limiters, preventing excessive rotation of the second disc 2 relative to the first disc 1 and thus avoiding collisions between them. Simultaneously, the mating of the first and second limiting parts indicates that the first disc 1 and the second disc 2 are connected. When the second disc 2 is rotated counterclockwise, the first connecting thread 5 and the second connecting thread 10 separate and loosen, thus separating the first and second limiting parts, and the first disc 1 and the second disc 2. Therefore, the assembly or disassembly process can be completed manually without additional tools, making it convenient to operate. Since the first disc 1 and the second disc 2 can be assembled, they can be reused, saving costs and avoiding waste.
[0041] The first limiting part of the embodiment comprises a limiting groove 6, and a limiting strip 7 is arranged in the limiting groove 6; the second limiting part comprises a limiting protrusion 8;
[0042] The second disc body 2 has a second disc surface part 11, and the connecting boss part 9 is arranged on the second disc surface part 11;
[0043] When the connecting boss part 9 enters the connecting cavity part 4 and the second disc surface part 11 abuts against the other end of the winding shaft 3, the limiting protrusion 8 is in the limiting groove 6 and abuts against the limiting strip 7. The above structure limits the assembly structure position between the first disc body 1 and the second disc body 2, so as to ensure that the two can be accurately assembled and connected.
[0044] Specifically, the shape of the first connecting thread part 5 is a right trapezoid, and the end face of the inclined side part of the first connecting thread part is an inclined face structure;
[0045] The number of the first connecting thread part 5 is two or more, and the first connecting thread part 5 is arranged in a clockwise spiral direction along the radial direction of the winding shaft 3.
[0046] Specifically, the number of the first limiting part is two or more, and the first limiting part is arranged corresponding to the position of the first connecting thread part 5;
[0047] The limiting strip 7 is arranged in the middle of the limiting groove 6, and one side slot of the limiting groove 6 is arranged in communication with the cavity of the connecting cavity part 4. The above structure facilitates the second limiting part to better enter the limiting groove 6 through the slot of the limiting groove 6 and the communication position of the cavity of the connecting cavity part 4 in the process that the connecting boss part 9 can enter the connecting cavity part 4 by rotation.
[0048] Specifically, the shape of the second connecting thread part 10 is a right trapezoid, and the end face of the inclined side part of the second connecting thread part is an inclined face structure;
[0049] The number of the second connecting thread part 10 is two or more, and the second connecting thread part 10 is arranged in a counterclockwise spiral direction along the radial direction of the connecting boss part 9.
[0050] The limiting protrusion 8 is arranged between the two adjacent second connecting thread parts 10.
[0051] Specifically, the cross section of the limiting protrusion 8 is a triangle.
[0052] Specifically, the triangular end of the limiting protrusion 8 is a round chamfer structure. The above round chamfer structure of the triangular end facilitates the movement of the limiting protrusion 8 in the limiting groove 6. When the limiting protrusion 8 cooperates with the limiting strip 7 to play a role of rotation limiting, the first connecting thread part 5 and the second connecting thread part 10 are separated and loosened.
[0053] Specifically, in the axial direction of the connecting boss part 9, the limiting protrusion 8 is between the second connecting thread part 10 and the second disc surface part 11.
[0054] The end surface of the bevel part of the first connecting thread part cooperates with the end surface of the bevel part of the second connecting thread part to achieve the effect of mutual engagement of threads.
[0055] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, without departing from the technical solution of the present application, still belongs to the scope of the technical solution of the present application.
