Description

Technical Field

[0001] This invention relates to the field of educational equipment technology, and in particular to a counter used for children's teaching. Background Technology

[0002] A children's educational counter is an intuitive teaching tool designed specifically for the early learning stage. It usually consists of an abacus with beads, a number wheel, or movable buttons. It mainly helps children establish their initial number sense, understand the correspondence between numbers and objects, master basic addition and subtraction concepts, and cultivate logical thinking skills through concrete operations. Currently, it is mainly used in kindergarten math enlightenment classes, auxiliary teaching in the lower grades of primary school, and parent-child early education scenarios at home.

[0003] In existing abacuses used for children's education, the U-shaped rods with beads are usually installed on the base of the abacus by fixing or plugging them in. Fixing the rods in this way makes it difficult to replace the beads individually later, increasing the cost of use. Plug-in abacuses require a large pulling force to remove, which can easily damage the rods. Furthermore, when the rods are pulled out forcefully, the beads may scatter, making them difficult to collect and increasing the risk of children swallowing them. This reduces efficiency and increases safety hazards. Summary of the Invention

Anti-scattering ratchet rods are placed inside the plurality of fixed cylinders, and one end of the plurality of anti-scattering ratchet rods is engaged with the corresponding plurality of ratchet plates.

[0011] In a preferred embodiment, the rotating fixing assembly includes a rotating shaft, the upper end of which is connected to the lower side of the counter base via a bearing, the lower end of which is fixedly connected to a fixing base, and the upper side of the fixing base is fixedly connected to a housing.

[0012] In a preferred embodiment, a fixed ratchet ring is fitted on the upper outer wall of the rotating shaft. The upper end of the fixed ratchet ring is connected to the lower side of the counter base. Multiple limiting rods are fixedly connected at equal intervals on the upper side of the fixed base. The multiple limiting rods are located outside the rotating shaft. Connecting plates are slidably connected to the outer walls of the multiple limiting rods. The same movable ratchet ring is fixedly connected to one side of the multiple connecting plates.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The counter disclosed in this invention for children's education is mainly applied to scenarios where the U-shaped rod installation method of existing counters for children's education has defects, fixed type has high replacement cost, plug-in type is easy to damage and the beads are prone to scattering and pose a risk.

[0020] Reference Figures 1-5 A counter for children's education includes a counter base 3, two counting unit plates 6 are fixedly connected at equal intervals on the upper side of the counter base 3, an indicator plate 7 is fixedly connected on the upper side of the counter base 3 and located between the two counting unit plates 6, a rotating fixing assembly 5 is provided on the lower side of the counter base 3, and multiple quick-release anti-scattering assemblies 4 are provided at equal intervals on the upper side of the counter base 3. The quick-release anti-scattering assembly 4 includes a fixing cylinder 402, multiple fixing cylinders 402 are fixedly connected at equal intervals on the upper side of the counter base 3, and the outer walls of the multiple fixing cylinders 402 are respectively connected to rotating rings 404 through bearings. Multiple short trapezoidal wedges 405 are fixedly connected at equal intervals at both ends of the multiple rotating rings 404.

[0021] In this invention, multiple fixing plates 409 are fixedly connected at equal intervals to the outer walls of both ends of the fixing cylinder 402, and the same guide rod 412 is fixedly connected to the opposite side of every two adjacent fixing plates 409.

[0022] In this invention, the outer walls of multiple guide rods 412 located on the same plane are slidably connected to the same conical unlocking ring 403. The two conical unlocking rings 403 are located on both sides of the rotating ring 404, respectively, and are arranged opposite to each other. The outer walls of the two conical unlocking rings 403 are provided with multiple unlocking grooves at equal intervals.

[0023] In this invention, a plurality of guide rods 412 are respectively fitted with a reset spring 408 on their outer walls. One end of the plurality of reset springs 408 is fixedly connected to the corresponding fixed plate 409, and the other end of the plurality of reset springs 408 is fixedly connected to the corresponding conical unlocking ring 403.

[0024] In this invention, two conical unlocking rings 403 are fixedly connected to each other on opposite sides with a plurality of long trapezoidal wedges 406 at equal intervals, and the inclined surfaces of the plurality of long trapezoidal wedges 406 abut against the inclined surfaces of the corresponding short trapezoidal wedges 405.

[0025] In this invention, multiple movable holes are equally spaced on the inner walls of multiple fixed cylinders 402. Movable rods 407 are slidably connected inside the multiple movable holes on the same fixed cylinder 402. One end of each pair of adjacent movable rods 407 inside the fixed cylinder 402 is fixedly connected to the same ratchet plate 411. Compression springs 410 are respectively sleeved on the outer walls of the multiple movable rods 407 inside the fixed cylinder 402. One end of the multiple compression springs 410 is fixedly connected to the corresponding ratchet plate 411, and the other end of the multiple compression springs 410 is fixedly connected to the inner wall of the fixed cylinder 402. Anti-scattering ratchet rods 401 are placed inside the multiple fixed cylinders 402. One end of the multiple anti-scattering ratchet rods 401 is engaged with the corresponding multiple ratchet plates 411.

[0026] Specifically, when it is necessary to replace the abacus 2, simply rotate the corresponding rotating ring 404. During the rotation of the rotating ring 404, the inclined surfaces of the multiple short trapezoidal wedges 405 on it slide relative to the inclined surfaces of the corresponding long trapezoidal wedges 406, thereby causing the corresponding long trapezoidal wedges 406 to move. The two conical unlocking rings 403 located on the same fixed cylinder 402 move towards the corresponding multiple movable rods 407 under the action of the corresponding multiple long trapezoidal wedges 406. During this process, when the multiple unlocking slots on the multiple long trapezoidal wedges 406 pass one end of the corresponding movable rods 407, the multiple movable rods 407 move outward, thereby pulling the corresponding ratchet plate 411 away from the anti-scattering ratchet rod 401, thus completing the unlocking of the anti-scattering ratchet rod 401. In this way, the U-shaped rod 1 can be disassembled. Finally, the abacus 2 can be replaced by unscrewing the corresponding anti-scattering ratchet rod 401.

[0027] In specific application scenarios, when the U-shaped rod 1 is disassembled, the ratchet rods 401 screwed onto the threaded ends 8 at both ends of the U-shaped rod 1 prevent multiple beads 2 from falling directly off the U-shaped rod after disassembly. This facilitates collection and prevents children from accidentally swallowing the beads, improving efficiency while reducing safety hazards.

[0028] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the rotating fixing assembly 5 includes a rotating shaft 510, the upper end of which is connected to the lower side of the counter base 3 via a bearing, the lower end of which is fixedly connected to a fixing base 505, and the upper side of the fixing base 505 is fixedly connected to a housing 502.

[0029] In this invention, a fixed ratchet ring 501 is sleeved on the upper outer wall of the rotating shaft 510. The upper end of the fixed ratchet ring 501 is connected to the lower side of the counter base 3. Multiple limiting rods 507 are fixedly connected at equal intervals on the upper side of the fixed base 505. The multiple limiting rods 507 are located outside the rotating shaft 510. The outer walls of the multiple limiting rods 507 are slidably connected to connecting plates 506. The same movable ratchet ring 509 is fixedly connected to one side of the multiple connecting plates 506. The movable ratchet ring 509 meshes with the fixed ratchet ring 501 and is sleeved on the outer wall of the rotating shaft 510.

[0030] In this invention, a telescopic spring 508 is sleeved on the outer wall of the rotating shaft 510. One end of the telescopic spring 508 is fixedly connected to the lower side of the movable ratchet ring 509, and the other end of the telescopic spring 508 is fixedly connected to the upper side of the fixed base 505. Two fixing holes are respectively opened on the upper side of the fixed base 505. Suction cups 503 are fixedly connected inside the two fixing holes respectively. The suction ends of the two suction cups 503 are respectively located on the lower side of the fixed base 505. Two anti-slip pads 504 are fixedly connected at equal intervals on the lower side of the fixed base 505.

[0031] Specifically, in use, the counter body is first placed in the desired position, and then the two suction cups 503 in the rotating fixing component 5 are used to attach the counter body to the desired position, thereby completing the installation and fixing of the counter body. The two suction cups 503 and the two anti-slip pads 504 greatly improve the stability of the counter body and prevent the counter body from sliding and falling due to external factors. At the same time, since the fixing base 505 is connected to the counter base 3 through the rotating shaft 510, the counter body can still be adjusted in angle after installation and fixing, thereby meeting different directional needs and greatly improving teaching efficiency. The movable ratchet ring 509 is always tightly engaged with the fixed ratchet ring 501 under the action of the telescopic spring 508, thereby improving the stability of the counter body after angle adjustment.

[0032] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the upper side of the multiple anti-scattering ratchet rods 401 is provided with threaded holes, and threaded ends 8 are screwed into the multiple threaded holes. The upper ends of every two opposite threaded ends 8 are fixedly connected to the same U-shaped rod 1, and multiple beads 2 are strung on the outer walls of the multiple U-shaped rods 1.

[0033] Working principle: In use, first place the counter body in the desired position, and then use the two suction cups 503 in the rotating fixing component 5 to attach to the position, thereby completing the installation and fixing of the counter body. The two suction cups 503 and the two anti-slip pads 504 greatly improve the stability of the counter body and prevent the counter body from sliding and falling due to external factors. At the same time, since the fixing base 505 is connected to the counter base 3 through the rotating shaft 510, the counter body can still be adjusted in angle after installation and fixing, thereby meeting the needs of different directions and greatly improving teaching efficiency. The movable ratchet ring 509 is always tightly engaged with the fixed ratchet ring 501 under the action of the telescopic spring 508, thereby improving the stability of the counter body after angle adjustment. When the abacus bead 2 needs to be replaced, simply rotate the corresponding rotating ring 404. During the rotation of the rotating ring 404, the inclined surfaces of the multiple short trapezoidal wedges 405 on it slide relative to the inclined surfaces of the corresponding long trapezoidal wedges 406, thereby causing the corresponding long trapezoidal wedges 406 to move. The two conical unlocking rings 403 located on the same fixed cylinder 402 move towards the corresponding multiple movable rods 407 under the action of the multiple long trapezoidal wedges 406. During this process, when the multiple unlocking grooves on the multiple long trapezoidal wedges 406 pass one end of the corresponding movable rods 407, the multiple movable rods... 407 moves outward, thereby pulling the corresponding ratchet plate 411 away from the anti-scattering ratchet bar 401, thus unlocking the anti-scattering ratchet bar 401. This allows the U-shaped bar 1 to be disassembled. As the U-shaped bar 1 is disassembled, the anti-scattering ratchet bar 401 screwed onto the threaded end 8 at both ends of the U-shaped bar 1 prevents multiple beads 2 from scattering directly from the U-shaped bar after disassembly. This facilitates collection and prevents children from accidentally swallowing the beads, improving efficiency and reducing safety hazards. Finally, the beads 2 can be replaced by unscrewing the corresponding anti-scattering ratchet bar 401.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
