[0039] To better understand the purpose, structure, and function of this utility model, a gashapon machine of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] like Figure 1-14 As shown, this utility model provides a gashapon machine, including a base 10 that provides overall support at the bottom, a lower housing 20 fixedly installed on the base 10 to accommodate a torsion assembly 50, an upper housing 30 snapped onto the upper part of the lower housing 20 for holding gashapon, a cover 40 covering the upper part of the upper housing 30, a torsion assembly 50 located inside the lower housing 20, and a support frame 60 that supports the torsion assembly 50; the torsion assembly 50 can receive gashapon falling from the upper housing 30 and carry the gashapon to rotate inside the lower housing 20, and when it rotates to a certain angle, the gashapon leaves the torsion assembly 50, falls onto the base 10, and rolls out.

[0041] The base 10 is generally disc-shaped, including a central cavity 15. The edge of the central cavity 15 is raised to a certain height to form an annular protrusion, which is the first step 16. The outer side of the first step 16 extends outward and sinks to a certain height to form an "outer ring low platform", which is the second step 17. The central cavity 15 is provided with a support member 11 for installing and supporting the torsion assembly 50, a tongue-shaped plate 12 for receiving the dropped capsule, a pair of lower guide plates 13 for guiding the capsule's fall, and four evenly arranged bolt mounting holes 18. The support member 11 is an integrally formed convex platform with a certain height. Its upper part has a "U"-shaped groove 111 for installing the first torsion bar 53. The depth of the "U"-shaped groove 111 is slightly greater than that of the first torsion bar 53. The support member 11 has a diameter of 3 and an internal limiting groove 112 for mounting the limiting plate 55. A pair of parallel and symmetrical locking strips 113 are arranged on the back of the support member 11 from top to bottom, and a locking groove 114 is formed in the middle of the pair of locking strips 113. One end of the tongue plate 12 abuts against the lower part of the support member 11, and the other end extends along the radial direction of the central cavity 15, passes through two steps, and extends outward to form an arc-shaped extension end. The height of the extension end is lower than the height of the abutting end. The lower guide plate 13 is located on both sides of the tongue plate 12, and its upper end can abut against the lower end of the upper guide plate 22 of the lower housing 20 to form a guide plate. Insertion holes 14 are provided at the positions where the tongue plate 12 intersects with the two steps, for the insertion of the connector 61 of the support frame 60.

[0042] The lower housing 20 is an axially continuous cylindrical shape, with a diameter at a specific height at the top that is smaller than the diameter at the bottom. It contains bolt mounting posts 26, each with a threaded hole at its end. These threaded holes mate with bolt mounting holes 18 on the base 10, allowing the lower housing 20 to be fixedly mounted to the base 10 using bolts. The outer diameter of the lower housing 20 matches the inner diameter of the first-stage step 16 of the base 10, ensuring the lower housing 20 fits snugly inside the first-stage step 16 after installation. The upper end of the lower housing 20 has an annular surface 24 with a circular opening at its center serving as an egg-drop hole 25. Symmetrical slots 241 on the annular surface 24 allow the guide fins 52 of the torsion assembly 50 to pass through. The outer edge of the annular surface 24 has a mounting groove 28 for the mounting portion 36 of the upper housing 30 to be engaged. The outer wall of the upper shell 30 is provided with L-shaped locking blocks 23, which can cooperate with the L-shaped slots 35 of the upper shell 30 to lock the upper shell 30 and the lower shell 20 together. The lower shell 20 is provided with a pressure plate 21. After installation, the pressure plate 21 presses against the upper part of the U-shaped groove 111 of the support member 11, closing the upper opening of the U-shaped groove 111. The lower shell 20 is provided with an upper guide plate 22. After installation, the lower end of the upper guide plate 22 can abut against the upper end of the lower guide plate 13 on the base 10 to form a guide plate. The lower shell 20 is provided with a pair of cat ear clips 29 for the cat ears 63 of the support frame 60 to be clipped in. The lower shell 20 is provided with an inverted U-shaped egg outlet 27 on the side. After installation, the egg outlet 27 is located on the upper part of the tongue plate 12 of the base 10.

[0043] The upper shell 30 is an overall lantern-shaped ellipsoid, composed of two hemi-ellipsoids that engage with the positioning slots 33 via positioning blocks 32, primarily used to hold gashapon capsules. Both its upper and lower parts have circular openings, with the lower opening having a larger diameter than the upper opening. The upper opening is for inserting gashapon capsules, which then fall into the twist container 51 of the twist assembly 50 through the lower opening. The edge of the upper opening has a first latch 31 through which the latch 41 of the cover 40 passes. The edge of the lower opening has a mounting portion 36. The upper housing 30 is provided with a second latch 34 and an "L"-shaped latch 35. The "L"-shaped latch 35 can cooperate with the "L"-shaped latch 23 of the lower housing 20 to latch and lock the upper housing 30 and the lower housing 20. When installing the upper housing 30, first align the second latch 34 of the upper housing 30 with the "L"-shaped latch 23 of the lower housing 20, insert the mounting part 36 into the mounting groove 28 of the lower housing 20, and rotate the upper housing 30 so that the "L"-shaped latch 35 and the "L"-shaped latch 23 of the lower housing 20 are latched and locked, thus completing the installation of the upper housing 30.

[0044] The cover 40 is provided on the upper opening of the upper housing 30. The lower edge of the cover 40 is provided with a buckle 41. The buckle 41 can rotate the cover 40 through the first latch 31 of the upper housing 30. The latch can engage with the edge of the upper opening of the upper housing 30, so that the cover 40 is firmly covered on the upper opening of the upper housing 30.

[0045] The torsion assembly 50 includes a torsion container 51 that is a hollow hemispherical structure, capable of holding a capsule toy. A pair of guide wings 52 are symmetrically arranged on both sides of the torsion container 51 along the center of the container opening. The guide wings 52 are shaped like wings and integrally formed with the torsion container 51. A first torsion bar 53 is integrally formed connected to the rear of the torsion container 51, and a second torsion bar 54 is integrally formed connected to its front. A limiting disc 55 is provided at a certain position on the first torsion bar 53, and a locking member 56 is integrally formed at its end. The locking member 56 is a circular disc structure, coaxially connected to the center of the first torsion bar 53. Two sets of irregularly shaped limiting members 561 are symmetrically distributed on the outer circumference of the locking member 56. The irregularly shaped limiting members 561 consist of an arc segment 5611 and a toothed segment 56. The support frame consists of 12 components. The arc segment 5611 is a smooth arc curve, providing an angular buffer zone for the torsion process. The toothed segment 5612 is a raised wedge-shaped tooth for mechanical locking. The first torsion bar 53 is rotatably installed in the "U"-shaped groove 111 of the support member 11, and the limiting plate 55 is installed in the limiting groove 112. After installation, the locking piece 56 at the end of the first torsion bar 53 is located on the back of the support member 11, and its toothed segment 5612 can be embedded in the locking groove 114 on the back of the support member 11. The second torsion bar 54 is rotatably installed in the torsion bar mounting hole 62 of the support frame 60 and extends outward through the torsion bar mounting hole 62. Its extended end is connected to a torsion handle 57. The torsion handle 57 has a bow-shaped structure, which is convenient for users to hold and apply rotational force.

[0046] The support frame 60 is generally in the shape of an inverted "U" and is fitted into the egg outlet 27 of the lower shell 20. The connector 61 at its lower end is inserted into the socket 14 of the base 10 and is engaged with the base 10. The pair of protruding "cat ears" 63 at the upper end are engaged with the "cat ear" clips 29 of the lower shell 20. A torsion bar mounting hole 62 is provided in the middle of the upper part of the support frame 60 for the second torsion bar 54 to be rotatably installed therein.

[0047] In use, first open the cover 40, fill the upper shell 30 with capsule toys, and then close the cover 40. Under the action of gravity, the capsule toys fall naturally through the lower opening of the upper shell 30 and the drop hole 25 of the lower shell 20 into the twist container 51 of the twist assembly 50, which can only hold one capsule toy at a time. When the user turns the twist handle 57 of the twist assembly 50, the second torsion bar 54 drives the twist container 51 to rotate synchronously. The guide fin 52 slides along the strip opening 241 to limit the rotation trajectory of the twist container 51. The twist container 51 and the guide fin 52 drive the twist to rotate. The capsule toy inside the rotating container 51 rotates with the container; when the rotation angle reaches 180°, the protruding tooth section 5612 of the locking piece 56 is inserted into the slot 114 on the back of the support piece 11, producing a "click" mechanical locking sound and a sudden change in resistance (indicating that the rotation is in place). At this time, the opening of the rotating container 51 faces downward, and the capsule toy falls naturally under the action of gravity. Guided by the guide fins 52 and the guide plate, it falls precisely onto the tongue plate 12. Under the action of the height difference between the inner and outer ends of the tongue plate 12, it rolls out from the egg outlet 27 along the tongue plate 12, completing the egg ejection. After the egg is ejected, hold the twist handle 57 and continue to rotate in the same direction. The toothed section 5612 of the locking piece 56 rotates out of the slot 114. The locking piece 56 first rotates along the arc section 5611. When the twist angle reaches 180° again, the other toothed section 5612 of the locking piece 56 is inserted into the slot 114 on the back of the support piece 11, producing a "click" mechanical locking sound and a sudden change in resistance (indicating that the twist is in place). At this time, the opening of the twist container 51 faces upward in the "waiting for the egg" posture, completing one gashapon output cycle.

[0048] The beneficial effects of this utility model are:

[0049] 1. This utility model adopts a modular snap-fit ​​and bolt-fixed assembly method (such as the "L"-shaped snap-fit ​​block 23 and "L"-shaped snap-fit ​​groove 35 of the upper shell 30 and the lower shell 20 cooperating, the support frame 60 being snapped to the base 10 and the lower shell 20 through the plug 61 and "cat ears" 63, the cover 40 being snapped to the upper shell 30, and the base 10 being bolted to the lower shell 20), which not only ensures the stability of the overall structure, but also reduces the risk of component loosening, and makes disassembly and maintenance more convenient, effectively reducing maintenance costs.

[0050] 2. This utility model utilizes the mechanical locking structure of the card 56 and the card slot 114 (the toothed section 5612 of the irregularly shaped limiting part 561 cooperates with the card slot 114 of the support part 11), which clearly indicates that the twisting is in place through a "click" sound and sudden change in resistance during the twisting process, allowing users to complete the operation without relying on visual judgment. The operation is simple and enhances the user experience.
