The form, number, ratio and 20 shown in the figures. The geometries are for illustrative purposes only, and different applications can be made as long as the technical function remains the same. It can be accomplished. The invention relates to the winding, storage, and feeding of filament used in 3D printers. It relates to a filament spool (10) used for controlled feeding. 25 The filament spool (10) consists of a detachable first spool part (20) and a second Includes reel part (30). When the first pulley part (20) and the second pulley part (30) are joined, the pulley It forms opposite side surfaces and there are 30 between these side surfaces. The filament winding area (60) that allows the filament to be wound is defined. The filament winding area (60) is the circumferential area around which the filament will be wound around the spool axis. It represents the volume and the surface area of the pulleys that support this volume. 6 The first pulley part (20) and the second pulley part (30) share a common axis of rotation. It includes central openings (70) located on it. The said central openings (70), when the parts are assembled a printer reel of filament spool (10) It enables attachment to a holder, carrier shaft, or equivalent support structure. The basic connection structure of the invention consists of at least one pulley part (20) located on the first pulley part. The locking element (40) and the second roller part (30) are located on the said locking gap (43) that meets the locking element (40), locking channel (44) and locking It is based on the ramp (45) working together. The locking element (40) consists of a longitudinally extending claw body (41) and the claw body. (41) contains a locking tab (42) located at the free end. The tab body (41), connected at one end to the first roller part (20) and containing the locking tab (42) in the form of a longitudinal and elastic body with its opposite end free It is being structured. 15 The nail body (41) runs from the first roller part (20) to the second roller part (30), will be in the axial direction of the pulley or will have a component of this direction It is positioned as follows. In the preferred configuration, the nail body (41) is the filament winding. 20 on the second pulley part (30) extending along the axial width of the region (60). It has a length that reaches up to the locking channel (44). Thus, the connection, between two main pulley parts at a short local fit on one edge of the pulley It is installed via the extending locking element (40). The nail body (41) allows a certain amount of elastic displacement during the locking process. 25 It is structured in such a way as to give. In the preferred application, the nail body (41) It acts as a cantilever element attached to the first pulley part (20); free When the locking tab (42) at its end contacts the locking ramp (45), the tab body (41) it deflected elastically and returned to its initial position after passing the ramp. It is turning. 30 The locking claw (42) is located at the free end of the claw body (41) and from the claw body (41) It is positioned to form an outward protrusion. The locking tab (42), with a sloping entry surface facing the locking ramp (45) and after locking the second A gripping surface for gripping the pulley part (30) may be available. Inclined entry 35 7 the surface contacts the locking ramp (45) and the claw body (41) in a controlled manner It contributes to its flexibility; the gripping surface is the second pulley after locking. It prevents axial separation by relying on the corresponding part of the piece (30). The locking clearance (43) located in the second pulley part (30) is 5 at the beginning of assembly. locking element (40) containing at least the claw body (41) and locking claw (42) It is designed with dimensions and geometry that will allow the tip to be retracted. The locking gap (43) is controlled into the opposite roller part of the locking element (40). This indicates the openness with which he entered in this manner. The locking channel (44) prevents the unwanted lateral movement of the locking element (40). to restrict and direct the locking tab (42) towards the locking ramp (45) It can be created. Locking channel (44), locking gap (43) and locking ramp. (45) extends between and the locking element (40) at least with the claw body (41) 15 in the form of a channel with a cross-section that can accommodate the locking tab (42). It is being structured. The locking ramp (45) moves in the direction of the locking tab (42) during the joining. It is a guiding surface that it contacts. Locking ramp (45), locking channel (44) an inclined 20 positioned in such a way that it will make contact with the locking tab (42) inside. It is the surface. Locking gap (43), locking channel (44) and locking ramp (45), claw along the longitudinal extension direction of the trunk (41) It is located. In the assembly process, the first pulley part (20) and the second pulley part (30) are common 25 They are positioned opposite each other so that their axes are aligned. Then The parts are brought closer together axially. During this movement... The locking tab (42) passes through the locking gap (43) and is inserted into the locking channel (44). and is directed to the locking ramp (45) by the locking channel (44). As the parts continue to move towards each other, the locking tab (42) locking ramp It slides on (45). Between the locking ramp (45) and the locking tab (42) Contact causes elastic displacement of the nail body (41). This displacement replacement, the necessary clearance for the locking tab (42) to pass the ramp geometry It provides. 35 8 When the locking tab (42) passes the locking ramp (45) completely, the ramp tab The steering effect on the body (41) is eliminated or reduced. As a result, the nail body (41) returns to its initial position under the influence of material flexibility. returning correctly and the locking tab (42) is back on the second roller part (30) 5 It is positioned in a way that prevents pulling. Thus, the first pulley part (20) The second pulley part (30) is locked together. This locking operation requires rotating the pulley parts relative to each other. It is not. Locking occurs by advancing the parts towards each other along the joining axis. 10 This allows the user to determine the angular position of the pulley parts. without performing a bayonet movement or a screw-like turning operation to change the position He is able to complete the assembly of the reel. In the preferred configuration, the locking element (40), the claw body (41) and the locking claw 15 (42) is manufactured integrated with the first pulley part (20). Similarly locking gap (43), locking channel (44) and locking ramp (45) second roller The part (30) is created on its own geometry. Thus, a separate locking mechanism is needed. Two rollers without the need for a spring, pin, screw, nut or separate locking part. Connection can be established using the structural elements of the part itself. 20 In one application, the filament spool (10), in the first spool part (20), filament at least positioned on opposite sides of the center opening (70) of the pulley (10) It contains two locking elements (40). In the second pulley part (30), the locking at least two 25 elements positioned to correspond to the positions of (40) locking gap (43), at least two locking channels (44) and at least two locking ramps (45) However, the number and circumferential placement of interlocking elements vary. It can be adjusted according to the size of the pulley and the desired clamping force. When the filament spool (10) needs to be removed, the user presses the locking element (40) 30 by reaching the claw body (41) in the direction of removing the locking claw (42) from the locked position It moves elastically. The locking tab (42) is attached to the second pulley part (30) when it stops getting stuck first pulley part (20) and second pulley part (30) They can be moved axially away from each other. 35 9 If more than one locking element (40) is used, the user must lock the elements (40) free separately or together as far as the pulley geometry allows. It can leave. In the preferred configuration, the locking elements (40) have claws. The free ends of their bodies (41) will be accessible around the central opening (70) It is positioned in such a way that a separate disassembly mechanism is located on the outer circumference of the reel. 5 The connection can be released without the need to establish one. After the first pulley part (20) and the second pulley part (30) are separated, the existing The filament can be removed from the spool and a new filament can be placed on the spool. The spool can be repositioned or prepared for filament winding. 10 Then the first pulley part (20) and the second pulley part (30) were again axially aligned. brought closer together and re-locked via the same locking elements (40) They can be locked together. This cycle is based on the elastic limits of the locking elements and the material. It can be repeated provided its durability is maintained. At least one of the first pulley part (20) or the second pulley part (30), center part It can include multiple strength elements (50) extending between the outer perimeter and the outer perimeter. Strength elements (50), load-bearing elements, support arms, intersecting supports, ribs or structural arrangements formed by them It is applicable. 20 The shape, number and placement of the strength elements (50) are not fixed. As seen in the figures The design reduces bending and torsion of the flanges while reducing weight and material usage. It is an example of a structure to support its rigidity. Strength elements (50), The locking forces are more evenly distributed from the center of the connection circumference to the roller surfaces. It can also contribute to the transfer of information. First pulley part (20), second pulley part (30), locking element (40) and others Structural components can be manufactured from polymer-based materials. Production is done by injection molding. molding, additive manufacturing or other suitable plastic forming methods 30 It can be realized. Material and production method, the necessary locking element (40) It allows for elastic movement and maintains its mechanical integrity during reuse. It can be selected in a way that will allow for its protection. The slope, length or surface form of the locking ramp (45); the claw body (41) flexibility, the amount of protrusion of the locking tab (42), the roller material and the intended It can be determined depending on the locking force. Similarly, the locking channel (44) The dimensions of the cross-section and the locking gap (43) control the movement of the locking element (40). It can be adapted to provide 5. Thanks to this design of the invention, the two pulley parts move directly with axial motion. quickly assembled; longitudinal nail body (41) to the opposite roller part extending to connect the two main parts; locking ramp (45) assembly converting its force into controlled elastic movement of the nail body (41) and locking 10 The claw (42) locks itself after passing the ramp. The user can lock himself or her. By releasing the locking element (40), the reel can be opened again. because it allows for filament change and spool reuse. It is being simplified.
