Description

Technical Field

[0001] The invention relates to the field of toy production, in particular to a doll with quicksand eyes and a manufacturing process thereof. Background Art

[0002] Doll eyelets are made by filling an eyeball-shaped container with glitter and other decorations, then filling it with quicksand oil and sealing it. These eyelets are widely used on toys and dolls, making the characters look incredibly vivid.

[0003] Because most users of toy dolls are children, they are often dropped or smashed, so the quality of toy dolls becomes particularly important, especially the reliability of drop tests and anti-fall tests, which is of paramount importance.

[0004] However, most conventional dolls’ quicksand eyes are simply glued together with some adhesive, and their reliability in falling and anti-falling is often not optimistic. This not only greatly reduces the service life of the toy doll, but in severe cases may even pose a safety hazard to children. Summary of the Invention

[0005] Based on this, it is necessary to provide a doll quicksand eye and a manufacturing process thereof in view of the deficiencies in the prior art.

[0006] A doll quicksand eye includes a main body, a base, a cover, and a back shell. The main body includes a front cover and a back cover. The front cover is sealed and fitted with the back cover, and the back cover is fitted with the upper end surface of the base. The cover is annular in design, fixedly fitted with the base and limiting the main body. The bottom end of the base is provided with a mounting post, and the back shell is provided with a corresponding mounting through hole. The mounting posts on the base are all embedded and fixed in the mounting through hole of the back shell. The doll quicksand eye also includes a sealing screw. An oil filling hole is also provided on the corresponding front cover of the main body, and an internal thread is provided on the inner side of the oil filling hole. The sealing screw is screwed into the oil filling hole to block and seal the oil filling hole.

[0007] Furthermore, the bottom edges of the front cover and the top cover of the main body are provided with female welding seats, and the top edges of the rear cover and the base are correspondingly provided with male welding seats. The female welding seats are engaged with the male welding seats.

[0008] Furthermore, the bottom edges of the front cover and the top cover of the main body are each provided with a fitting ring, and the top edges of the rear cover and the base are each provided with a corresponding fitting groove, and the fitting ring fits into the fitting groove. The bottom of the fitting ring is provided with a female welding seat, and the bottom of the fitting groove is provided with a male welding seat.

[0009] Furthermore, the outer periphery of the front cover of the main body is provided with a flange, the front cover includes a fixing portion and a stopper at the upper end of the fixing portion, and the back shell includes a bottom shell and sidewalls surrounding the edge of the bottom shell. The stopper is used to limit the flange, thereby limiting the position of the entire main body. The outer end surface of the sealing screw abuts against the inner side surface of the stopper, and the height of the sidewall is greater than or equal to the sum of the thickness of the base and the height of the front cover.

[0010] Furthermore, the mounting post is provided with an annular chamfer, and a plurality of elastic bayonet holes are provided corresponding to the mounting through holes, and an elastic slot is provided between any two elastic bayonet holes.

[0011] In addition, the present invention also provides a process for making a doll's quicksand eye, which is used to make the doll's quicksand eye, and comprises the following steps:

[0012] Step 1: Component molding, using methods including but not limited to 3D printing or injection molding to produce the various components of the doll's quicksand eye, including the front cover of the main body, the back cover of the main body, the base, the top cover, the back shell and the sealing screws;

[0013] Step 2: Punch a hole on one side of the front cover of the main body to make an oil filling hole that runs through both the inside and outside.

[0014] Step 3: Fill and seal, put the decorations into the front cover of the main body, then buckle and weld the rear cover of the main body with the front cover of the main body to form the main body;

[0015] Step 4: Fill the hole with oil. Stand the main body upright with the oil hole facing upwards. Use injection to fill the quicksand oil from the oil hole into the main body. Then plug the oil hole with a sealing screw and seal it with glue.

[0016] Step 5: Fix the main body, place the main body on the base, then buckle the cover from top to bottom and weld it to the base, so that the main body is fixed on the base;

[0017] Step 6: Engage the back shell and place it on the back of the doll's fabric. The base is then engaged and fixed on the back shell from the front of the fabric.

[0018] Furthermore, step 2 also includes a tapping operation, that is, tapping the drilled oil filling hole to form a thread on its inner side. When the sealing screw blocks the hole in step 4, the sealing screw can be screwed into the oil filling hole in the thread direction.

[0019] Furthermore, the welding methods in step 3 and step 5 are both ultrasonic welding.

[0020] Furthermore, step 4 also includes a static defoaming operation, that is, after the quicksand oil is injected into the main body and before the oil filling hole is blocked with a sealing screw, the main body can be kept upright and static for a period of time to further eliminate bubbles generated during the oil filling process.

[0021] To sum up, the beneficial effects of the doll quicksand eye and its manufacturing process of the present invention are: by designing fasteners to limit and fix the main body instead of the traditional pasting and fixing method, the fastening and firmness of the doll quicksand eye after assembly is greatly improved; the main body is designed with double welding positions for welding and sealing, which significantly enhances the sealing performance of the main body; the oil filling hole on the main body makes it easier to inject quicksand oil into the main body, and effectively reduces problems such as splashing and bubbles during oil filling; the fasteners and the back shell are designed to have appropriate heights to cover the edge sealing of the product, making it more beautiful; and the annular chamfer on the mounting column cooperates with the elastic bayonet on the mounting through hole, so that the base and the back shell are easier to buckle together and are firm and not easy to loosen; the present invention is highly practical and has strong promotional significance.

[0026] In order to make the purpose, technical solutions and advantages of the invention more clearly understood, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the invention and are not intended to limit the invention.

[0027] like Figures 1 to 4 As shown, the present invention provides a doll quicksand eye 100, comprising a main body 10, a base 20, a cover 30 and a back shell 40, wherein the base 20, the main body 10 and the cover 30 are sequentially installed in the back shell 40 from the inside to the outside.

[0028] The main body 10 includes a main body front cover 11 and a main body rear cover 12. The main body front cover 11 is sealed and fitted with the main body rear cover 12, and the main body rear cover 12 is fitted with the upper end surface of the base 20. A flange portion 13 is provided along the outer peripheral edge of the main body front cover 11. A welding female seat 51 is provided at the bottom edge of the main body front cover 11, and a welding male seat 52 is correspondingly provided at the top edge of the main body rear cover 12. The welding female seat 51 is engaged with the welding male seat 52. In this embodiment, there are two welding female seats 51 on the main body front cover 11, and two corresponding welding male seats 52 are also provided on the main body rear cover 12. The design of double welding positions makes the sealing performance of the main body 10 more reliable.

[0029] The main body front cover 11 has a mating ring 61 at its bottom edge, and the main body rear cover 12 has a mating groove 62 at its top edge. The mating ring 61 engages with the mating groove 62. The bottom of the mating ring 61 has a female welding socket 51, and the bottom of the mating groove 62 has a male welding socket 52. The mating ring 61 and the mating groove 62 facilitate alignment and assembly of the various components.

[0030] The cover 30 is annular in design and includes a fixing portion 31 and a stopper 32 at the upper end of the fixing portion 31. The stopper 32 is used to limit the position of the flange portion 13. The bottom end of the base 20 is provided with a mounting post 21, which is provided with an annular chamfer 22. The cover 30 and the base 20 snap together to limit the position of the entire main body 10. Compared to simple adhesive fixation, the snap-fit ​​between the cover 30 and the base 20 provides a more powerful fastening and limiting capability for the main body 10.

[0031] The bottom edge of the cover 30 and the top edge of the base 20 are also provided with a fitting ring 61 and a fitting groove 62, respectively. The bottom of the fitting ring 61 and the bottom of the fitting groove 62 are also provided with a corresponding welding female seat 51 and a welding male seat 52. The welding female seat 51 is fitted with the welding male seat 52, and the fitting ring 61 is fitted with the fitting groove 62.

[0032] The back shell 40 includes a bottom shell 42 and a side wall 43 surrounding the edge of the bottom shell 42. The back shell 40 is also provided with a mounting hole 41. The mounting hole 41 is provided with a plurality of elastic snap-in holes 44, and an elastic slot 45 is provided between any two elastic snap-in holes 44. The mounting posts 21 on the base 20 are all correspondingly engaged and fixed in the mounting holes 41 of the back shell 40. The height of the side wall 43 is greater than or equal to the sum of the thickness of the base 20 and the height of the cover 30. The design of the elastic snap-in holes 44 and the elastic slot 45 allows the mounting hole 41 to have a certain radial expansion elastic force, which facilitates the engagement and penetration of the mounting post 21 with the annular chamfer 22. The annular chamfer 22 allows the mounting post 21 to only be engaged and penetrated in the mounting hole 41 in one direction, preventing the base 20 from falling off the back shell 40, thereby greatly enhancing the reliability of the product. The side wall 43 of the back shell 40 can stretch the fabric to cover the edge of the quicksand eye 100 of the doll, so that when the product is installed on the doll, only the appearance of the front cover 11 of the main body is displayed, which significantly improves the aesthetics of the product.

[0033] The doll quicksand eye 100 also includes a sealing screw 70, and the oil filling hole 14 is also provided on the corresponding front cover 11 of the main body. The inner side of the oil filling hole 14 is provided with an internal thread. The sealing screw 70 is screwed into the oil filling hole 14 to block and seal the oil filling hole 14. The outer end face of the sealing screw 70 abuts against the inner side face of the limiting portion 32. The oil filling hole 14 is provided to inject quicksand oil into the main body 10 through the oil filling hole 14 through a syringe, which can effectively reduce the problems of leakage and bubbles when filling the quicksand oil. The limiting portion 32 of the cover 30 not only serves as a limiting and fastening function, but also can cover the oil filling hole 14, further improving the aesthetics of the product.

[0034] To assemble the quicksand eyelet of the present invention, first, close the main body rear cover 12 and main body front cover 11 to form the main body 10. Then, place the main body 10 on the base 20. Finally, snap the top cover 30 downwards and secure it to the base 20, securing the main body 10 to the base 20. Finally, fit the base 20 onto the back shell 40.

[0035] In addition, the present invention also provides a manufacturing process for a doll quicksand eye 100, which is used to manufacture the doll quicksand eye 100, and includes the following steps:

[0036] Step 1: Component molding: Using 3D printing, various components of the doll quicksand eye 100 are produced, including the main body front cover 11, the main body rear cover 12, the base 20, the surface cover 30, the back shell 40 and the sealing screws 70;

[0037] Step 2: Punch a hole 14 through the inner and outer sides of the front cover 11 on one side edge of the main body, and then tap the oil filling hole 14 to form a thread on the inner side;

[0038] Step 3: Fill and seal. Place decorations (such as glitter powder) into the main body front cover 11 , then snap the main body rear cover 12 onto the main body front cover 11 and seal them using ultrasonic welding. Together, the two form the main body 10 .

[0039] Step 4: Fill the hole with oil. Stand the main body 10 upright with the oil hole 14 facing upward. Use injection to inject quicksand oil into the main body 10 from the oil hole 14. Then keep the main body 10 upright and let it stand for a while to further eliminate bubbles generated during the oil filling process. Then, plug the oil hole 14 with the sealing screw 70. When plugging the hole, screw the sealing screw 70 into the oil hole 14 according to the thread direction and apply glue to seal it.

[0040] Step 5: Fix the main body 10 and place it on the base 20. Then, buckle the cover 30 from top to bottom and weld it to the base 20 using ultrasonic welding, so that the main body 10 is fixed on the base 20.

[0041] Step 6: Engage the back shell 40 and place it on the back of the fabric of the doll. The mounting post 21 on the base 20 is aligned with the mounting hole 41 from the front of the fabric and penetrated and engaged. The annular chamfer 22 on the mounting post 21 cooperates with the elastic bayonet 44 on the mounting hole 41, allowing the mounting post 21 to penetrate and engage from the front to the back, but not allowing the mounting post 21 to retreat and loosen from the back to the front.

[0042] To sum up, the beneficial effects of the doll quicksand eye 100 and its manufacturing process of the present invention are: by designing fasteners to limit and fix the main body 10 instead of the traditional pasting fixing method, the fastening and firmness of the doll quicksand eye 100 after assembly is greatly improved; the main body 10 is designed with double welding positions for welding sealing, so that the sealing performance of the main body 10 is significantly enhanced; the oil filling hole 14 on the main body 10 makes it easier to inject quicksand oil into the main body 10, and effectively reduces problems such as splashing and bubbles during oil filling; the fasteners and the back shell 40 are designed with appropriate heights to cover the product edge sealing, making it more beautiful; and the annular chamfer 22 on the mounting column 21 cooperates with the elastic bayonet 44 on the mounting through hole 41, so that the base 20 and the back shell 40 are easier to buckle together and are firm and not easy to loosen; the present invention is highly practical and has strong promotional significance.
