Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling toy technology, and in particular to a circular toy rolling mechanism and an egg rolling toy. Background Technology
[0002] Among toys, rolling toys are a type of simple to play with. These toys use the weight of the rolling parts to move. When playing, children need to place the rolling parts on the track. As the rolling parts roll down the track, it can help train children's visual tracking ability. In order for the rolling parts to roll down the track, the rolling parts are usually designed to be oval, spherical, etc.
[0003] Most existing toy rolling devices adopt a vertical drop structure design, that is, the track frame is equipped with a vertical slide rail. When playing, the rolling ball is placed on the vertical slide rail, and the rolling ball rolls down under its own weight. However, the gameplay of this type of track ball toy is monotonous. The rolling ball falls quickly after being placed on the vertical slide rail. The speed is fast and the fun is low, making it difficult to attract young children to play. Secondly, the device lacks an effective limiting mechanism, so it cannot achieve the effect of a single press rolling down a single rolling ball. Multiple rolling balls often roll down in succession, requiring frequent picking up and resetting, which seriously affects the continuity of the game.
[0004] Therefore, there is an urgent need to improve the design of a circular toy rolling mechanism and an egg rolling toy to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a rolling mechanism for a circular toy, thereby overcoming the deficiencies in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circular toy rolling mechanism, comprising a rolling base, a locking component, and a locking plate. The rolling base is provided with a first track for placing a circular toy. The upper end of the first track is connected to the top wall of the rolling base and has a toy inlet. The lower end of the first track is connected to the bottom wall of the rolling base and has a toy outlet. The rolling base is provided with a second track for sliding the locking component and a track opening for sliding the locking plate. The first track and the second track are connected. The locking component and the locking plate are arranged back and forth along the first track. When the locking plate is in the first track, the locking component is in the second track.
[0007] When the card is in the first track, the card plate slides off the first track, thereby discharging a single round toy.
[0008] The first track is inclined downwards from the toy inlet toward the toy outlet.
[0009] The tilt angle of the first track is 25°±5°.
[0010] It also includes a baffle for connecting the card plate and the card, and the baffle is slidably assembled with the rolling base.
[0011] The rolling base includes a side plate and a track plate mounted on the side plate. The baffle is slidably mounted on the side plate. The side plate has a toy inlet hole, and the toy inlet is connected to the toy inlet hole.
[0012] The inner wall of the side plate is provided with a mounting groove, and the inner wall of the mounting groove is provided with a first mounting hole. The outer wall of the track plate is provided with a mounting post that is adapted to the mounting groove. The mounting post is provided with a second mounting hole, and the first mounting hole and the second mounting hole are connected.
[0013] The inner wall of the side plate is provided with a sliding groove, and the outer wall of the baffle is provided with a convex strip, which is slidably assembled in the sliding groove.
[0014] The card includes a protrusion for insertion between two adjacent round toys, and the protrusion is located at the bottom of the card.
[0015] The protrusion is designed to gradually narrow downwards from the bottom wall of the card.
[0016] The card also includes a sliding part and a snap-fit part. The sliding part is slidably assembled on the inner side wall of the second track. The inner wall of the baffle is provided with a limiting protrusion, which snaps into the snap-fit part.
[0017] The horizontal straight-line distance between the card and the card plate is 1-1.1 times the width of the round toy.
[0018] It also includes a pressing member mounted on the track plate, the pressing member being connected to the baffle and used to push the baffle to slide toward the first track.
[0019] The outer wall of the pressing member is provided with a mating rod, and the inner wall of the baffle is provided with a first connecting post. The first connecting post has a first connecting hole for connecting with the mating rod.
[0020] It also includes a spring and a connecting plate for assembly with the bottom wall of the track plate. One end of the spring is connected to the bottom of the pressing member, and the other end of the spring is connected to the top wall of the connecting plate.
[0021] The pressing member has a connecting rod protruding in the direction away from the baffle, and the spring is connected to the pressing member through the connecting rod.
[0022] The track plate also includes a pressing platform for assembling the pressing component. The pressing platform has an assembly hole adapted to the pressing component. The inner wall of the pressing platform has a second connecting post protruding from it. The inner wall of the pressing component has a second connecting hole adapted to the second connecting post.
[0023] It also includes a counterweight block, and the card has a counterweight groove inside that is adapted to the counterweight block. The counterweight block is assembled in the card through the counterweight groove.
[0024] An egg-rolling toy including the aforementioned circular toy rolling mechanism further includes a base frame, a receiving platform, an egg pressing component, and an egg track assembled inside the base frame. The circular toy rolling mechanism is assembled with the base frame. The egg track is located below the toy outlet, and the receiving platform is located below the egg track. The egg pressing component has a pressing groove inside, and the egg pressing component is assembled with the pressing column through the pressing groove.
[0025] The beneficial effects of this utility model are as follows: By designing the first track to be inclined downwards from the toy inlet to the toy outlet, the rolling speed of the round toy is significantly reduced compared to the existing vertical falling structure. This allows the round toy to form a continuous, slow sliding trajectory along the inclined surface. This not only extends the movement time of a single roll, making it easier for young children to clearly observe the dynamic trajectory of the round toy and improve the visual tracking training effect, but also effectively enhances the visual appeal and playability of the toy. At the same time, the slow rolling process gives young children sufficient reaction time, significantly improving the fun and safety of the game.
[0026] Through the coordinated action of the locking mechanism and the baffle, a single circular toy limiting mechanism is formed within the second track. When the pressing component is pressed down, the locking component releases the first circular toy and guides it to roll down independently, while subsequent toys are blocked by the locking plate outside the toy entry hole. This structural design effectively solves the technical defect of multiple circular toys rolling down continuously in traditional devices. By controlling the release of the circular toys one by one, it avoids the interference of frequent picking up and resetting on the continuity of the game, and also allows children to exercise their fine motor skills through pressing operations, thereby enhancing the interactivity and educational value of the toys.

When a feature is referred to as "set," "fixed," or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.
[0039] In the description of this utility model, the term "several" means one or more, and "multiple" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number. The terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the quantity of indicated technical features, or the sequential relationship between indicated technical features.
[0040] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.
[0041] Example 1: As Figure 1-8As shown, a circular toy rolling mechanism includes a rolling base, a locking piece 3, and a locking plate 10. The rolling base has a first track 6 for placing circular toys. The upper end of the first track 6 is connected to the top wall of the rolling base and has a toy inlet 8. The lower end of the first track 6 is connected to the bottom wall of the rolling base and has a toy outlet 9. The rolling base has a second track 7 for the locking piece 3 to slide and a track opening 11 for the locking plate 10 to slide. The first track 6 and the second track 7 are connected. The locking piece 3 and the locking plate 10 are arranged back and forth along the first track 6. When the locking plate 10 is in the first track 6, the locking piece 3 is in the second track 7. The design of the locking plate 10 can prevent the circular toy from sliding down the first track 6 without moving the locking piece 3. After the locking piece 3 slides, the locking plate 10 leaves the first track 6 through the track opening 11, causing a circular toy to fall. At the same time, the locking piece 3 moves to the intersection of the first track 6 and the second track 7 to block subsequent circular toys, thus allowing the circular toys to fall one by one.
[0042] When the card 3 is in the first track 6, the card plate 10 slides away from the first track 6, thereby discharging a single round toy.
[0043] The first track 6 is inclined downward from the toy inlet 8 toward the toy outlet 9. The inclined first track 6 reduces the rolling speed of the round toy and makes it easier to observe the rolling situation.
[0044] The tilt angle of the first track 6 is 25°±5°. By limiting the tilt angle of the first track 6, it is easier to achieve a better rolling speed for the round toy.
[0045] It also includes a baffle 2 for connecting the card plate 10 and the card 3. The baffle 2 is slidably assembled with the rolling base. The baffle 2 facilitates the synchronous movement of the card 3 and the card plate 10, reducing the difficulty of operation.
[0046] The rolling base includes a side plate 1 and a track plate 4 mounted on the side plate 1. A baffle 2 is slidably mounted on the side plate 1. The side plate 1 has a toy inlet 5. The toy inlet 8 is connected to the toy inlet 5. The assembly relationship between the side plate 1 and the track plate 4 facilitates the assembly and maintenance of the rolling base.
[0047] The inner wall of the side plate 1 is provided with a mounting groove 14, and the inner wall of the mounting groove 14 is provided with a first mounting hole 15. The outer wall of the track plate 4 is provided with a mounting post 16 that is adapted to the mounting groove 14. The mounting post 16 is provided with a second mounting hole 17. The first mounting hole 15 and the second mounting hole 17 are connected. The mounting groove 14 on the inner wall of the side plate 1 and the mounting post 16 on the track plate 4 are assembled by plugging. The first mounting hole 15 in the mounting groove 14 and the second mounting hole 17 in the mounting post 16 can be connected by bolts or buckles to realize the detachable fixation of the track plate 4 and the side plate 1, which is convenient for assembly and maintenance.
[0048] The inner wall of the side plate 1 is provided with a sliding groove 12, and the outer wall of the baffle 2 is provided with a convex strip 13. The convex strip 13 is slidably assembled in the sliding groove 12. By sliding the convex strip 13 up and down in the sliding groove 12, the movement direction of the baffle 2 is restricted, ensuring that the baffle 2 slides stably on the side plate 1 and avoiding deviation or jamming.
[0049] The clip 3 includes a protrusion 36, which is used to insert between two adjacent round toys. The protrusion 36 is located at the bottom of the clip 3, and the protrusion 36 facilitates the limiting of adjacent round toys.
[0050] The protrusion 36 is designed to gradually contract and protrude downwards from the bottom wall of the clip 3. By defining the shape of the protrusion 36, it is possible to better limit the positioning of adjacent round toys.
[0051] The locking component 3 further includes a sliding part 37 and a locking part 38. The sliding part 37 is slidably mounted on the inner wall of the second track 7. The inner wall of the baffle 2 is provided with a limiting protrusion 18, which is locked with the locking part 38. With the setting of the sliding part 37, the locking part 38, and the limiting protrusion 18, when the baffle 2 slides, the limiting protrusion 18 drives the sliding part 37 in the locking component 3 to move synchronously in the second track 7. The displacement of the locking component 3 realizes the blocking or release of the round toy.
[0052] The horizontal straight-line distance between the card 3 and the card plate 10 is 1-1.1 times the width of the round toy. The distance between the two is limited to make it easier to block only one round toy at a time.
[0053] It also includes a pressing member 19 mounted on the track plate 4. The pressing member 19 is connected to the baffle 2 and is used to push the baffle 2 to slide toward the first track 6. The pressing member 19 facilitates the control of the sliding process of the baffle 2.
[0054] The outer wall of the pressing member 19 has a protruding mating rod 20, and the inner wall of the baffle 2 has a protruding first connecting post 21. The first connecting post 21 has a first connecting hole 22 for connecting with the mating rod 20. The mating rod 20 of the pressing member 19 and the first connecting post 21 of the baffle 2 are connected through the first connecting hole 22. When the pressing member 19 is pressed, the mating rod 20 drives the baffle 2 to slide downward, releasing the locking member 3 from the first round toy. At the same time, the locking plate 10 blocks subsequent round toys, realizing the mechanical control of releasing them one by one.
[0055] It also includes a spring 23 and a connecting plate 39 for mounting to the bottom wall of the track plate 4. One end of the spring 23 is connected to the bottom of the pressing member 19, and the other end of the spring 23 is connected to the top wall of the connecting plate 39. The spring 23 facilitates automatic reset of the pressing process and improves the convenience of pressing operation.
[0056] The pressing member 19 has a connecting rod 24 protruding in the direction away from the baffle 2. The spring 23 is connected to the pressing member 19 through the connecting rod 24. The connecting rod 24 on the pressing member 19 is connected to the spring 23. When pressed, the spring 23 is compressed to store energy. After releasing, the spring 23 rebounds and drives the pressing member 19 to reset, so that the baffle 2 and the locking member 3 return to their initial positions, ensuring that the mechanism automatically resets after each press and maintaining the function of continuous operation.
[0057] The track plate 4 further includes a pressing platform 25 for assembling the pressing member 19. The pressing platform 25 has an assembly hole 26 adapted to the pressing member 19. The inner wall of the pressing platform 25 has a second connecting post 27 protruding from it. The inner wall of the pressing member 19 has a second connecting hole 28 adapted to the second connecting post 27. The pressing platform 25 of the track plate 4 cooperates with the pressing member 19 through the assembly hole 26. The second connecting post 27 is inserted into the second connecting hole 28 of the pressing member 19 to restrict the movement trajectory of the pressing member 19, avoid pressing deviation, ensure that the pressing force is transmitted vertically to the baffle 2, and improve the operational stability.
[0058] The pressing member 19 has a pressing post 29 protruding towards the baffle 2. The connecting post passes through the assembly hole 26. The pressing post 29 of the pressing member 19 towards the baffle 2 passes through the assembly hole 26. The pressing post 29 reduces the contact area when pressing, which facilitates the concentration of force and directly transmits the pressing force to the mechanism in the egg track 34, triggering the rolling action of the egg toy.
[0059] The device also includes a counterweight 31. The card part 3 has a counterweight groove 30 that is adapted to the counterweight 31. The counterweight 31 is assembled in the card part 3 through the counterweight groove 30. The counterweight 31 can increase the weight of the card part 3, so that the complex card part 3 can be made of lightweight materials, such as wood or plastic, which can reduce production costs.
[0060] Example 2: As Figure 9 As shown, an egg-rolling toy includes a circular toy rolling mechanism as described in Embodiment 1, and further includes a base frame 32, a receiving platform 35, an egg-pressing component 33, and an egg track 34 assembled inside the base frame 32. The circular toy rolling mechanism is assembled with the base frame 32. The egg track 34 is located below the toy outlet 9, and the receiving platform 35 is located below the egg track 34. The egg-pressing component 33 has a pressing groove inside, and is assembled with the pressing post 29 through the pressing groove. The egg track 34 is assembled inside the base, and the egg-pressing component 33 is connected to the pressing post 29 through the pressing groove. When the egg-pressing component 33 is pressed, it activates the circular toy rolling mechanism, causing the egg-shaped toy to roll from the track to the receiving platform 35, simulating the process of an egg rolling.
[0061] The round toy described in Example 1 is a toy egg in this example.
[0062] The implementation principle of the egg-rolling toy in this embodiment is as follows: When in use, the operator puts multiple round toys into the toy inlet 8 of the track plate 4. The round toys roll down the downward-sloping first track 6 and are blocked at the blocking plate 10. At this time, the egg pressing component 33 is pressed, which drives the pressing column 29 to press down. The pressing component 19 slides down along the sliding groove 12 of the side plate 1 through the linkage rod 20 and the baffle 2. The blocking plate 10 of the baffle 2 disengages from the first track 6 through the track opening 11, releasing the first round toy that is close to the blocking plate 10 to roll down to the toy outlet 9. Then, it enters the receiving platform 35 along the egg track 34. At the same time, the limiting protrusion 18 pulls the blocking component 3 down to the junction of the second track 7 and the first track 6 to block the subsequent egg toys. When the egg pressing component 33 is released, the spring 23 rebounds through the connecting rod 24 to push the pressing component 19 to reset. The baffle 2 rises and the blocking plate 10 is reinserted into the track opening 11 to continue blocking the subsequent round toys, thus achieving the fun rolling effect of the cyclical toy release.

Any person skilled in the art can easily conceive of various equivalent modifications and substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
