Description

Technical Field

[0001] The utility model relates to the technical field of the improved design of chopstick auxiliary components, in particular to a pair of chopsticks convenient for use and practice. Background Art

[0002] Chopsticks are not simply eating utensils, but as a world cultural heritage unique to Eastern culture, using chopsticks from an early age helps with brain development. In particular, when children are 3 to 6 years old, their intelligence coefficients are almost formed, and whether to use chopsticks during this period is quite important for intelligence development. Not only do the movements of each finger when using chopsticks give a lot of stimulation to the brain, but chopsticks are also the best tool for using all five fingers comprehensively. The delicate hand movements when using chopsticks in childhood give stimulation to the brain and are very helpful for brain development. For ordinary chopsticks nowadays, children under 3 - 4 years old are difficult to learn and can hardly use them due to the underdevelopment of small muscles. Children are easily bored, resulting in an incorrect usage posture being fixed, thus missing the best educational period.

[0003] Currently, there are some practice chopsticks, but they lack a clamping function. After the length of the chopsticks is adjusted to a suitable position, they are locked, and the locking function is relatively single. Therefore, the practice function is still limited.

[0004] A patent with the publication number CN220344152U discloses a pair of practice chopsticks, including a main body seat and two supporting feet. A pressing and locking component is arranged inside the main body seat. The two supporting feet respectively pass through the main body seat, so that the upper ends of the two supporting feet extend above the main body seat, and the lower ends of the two supporting feet extend below the main body seat. A plurality of locking slots are arranged on both supporting feet along the width direction of the supporting limbs. After the pressing and locking component receives an external pressing force, it moves along the radial direction of the main body seat. When the pressing and locking component is aligned and clamped with the locking slots on the supporting feet, locking is formed, so that the supporting feet cannot move any more in the length direction of the supporting feet. The utility model can flexibly lock the supporting feet in the length direction by using the pressing and locking component, avoid the up and down sliding of the supporting feet, and at the same time can adjust the extending length of the supporting feet to meet the usage requirements of different children, with simple operation.

[0005] In the above technical solution, since the pressing and locking component is located inside the main body seat, both ends of the spring are respectively connected to the rear shell and the pressing block. Locking protrusions are arranged on the inner walls of the guide grooves on both sides of the pressing block. When the locking protrusions are inserted into the locking slots, locking of the supporting feet is formed. The main body seat includes a front shell and a rear shell. Once disassembled, it may be impossible to assemble the pressing and locking component.

[0006] This application provides a pair of chopsticks convenient for use and practice to solve one of the above problems. Content of the Utility Model

[0032] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Referring to Figures 1 - 10 As shown, a pair of chopsticks 6 for easy use and practice of the present invention includes a main body seat and a pair of chopsticks 6. The chopsticks 6 are movably inserted into the receiving holes on the main body seat. Specifically, two receiving holes are provided on the main body seat, and each chopstick 6 passes through one receiving hole, so that the upper ends of the two chopsticks 6 extend above the main body seat, and the lower ends of the two chopsticks 6 extend below the main body seat. A plurality of locking slots 63 are provided on the chopsticks 6 along the width direction. A sliding locking assembly is provided in the main body seat. The sliding locking assembly includes side limit posts 24 and elastic limit protrusions 25 respectively arranged on both sides of the receiving hole. The elastic limit protrusions 25 elastically clamp the locking slots 63 and make the side limit posts 24 abut against the chopsticks 6. The locking slots 63 cooperate with the elastic limit protrusions 25, and the elastic limit protrusions 25 have an elastic reset function. During normal use, since the chopsticks 6 are elastically limited by the side limit posts 24 and the elastic limit protrusions 25, the locking slots 63 at different positions correspond to different adjusted lengths. When adjusting the length of the chopsticks 6, only need to move up and down to make the elastic limit protrusions 25 clamp the corresponding locking slots 63. An adjustment groove 20 is opened on the main body seat, and a sliding cover 5 is slidably embedded in the adjustment groove 20. An adjustment block 50 is provided on the sliding cover 5. The adjustment block 50 is inserted into the adjustment groove 20 and the adjustment block 50 is located between the two elastic limit protrusions 25. The adjustment block 50 moves linearly with the sliding cover 5 and abuts against the elastic limit protrusions 25 to limit the movement of the chopsticks 6 in the length direction. When the sliding cover 5 is pushed by an external force and moves along the radial direction of the main body seat, the adjustment block 50 is in the reset vacancy of the elastic limit protrusion 25. At this time, the elastic limit protrusion 25 does not have a reset function, and the chopsticks 6 are completely locked and clamped by the sliding locking assembly, that is, the chopsticks 6 can no longer move in the length direction of the chopsticks 6.

[0036] The chopsticks 6 can be adjusted in the length direction, that is, the length of the chopsticks 6 below the main body seat can be adjusted. For example, push or pull the chopsticks 6 upward along the receiving hole to shorten the length of the chopsticks 6 extending below the main body seat. At this time, the use requirements of younger children can be met. After adjusting the length, the elastic clamping function of the sliding locking assembly can ensure stability.

[0037] Embodiment 2

[0038] Referring toFigures 1 - 10 As shown, based on the technical solution of the first embodiment, a pair of chopsticks convenient for use and practice, a rib plate is provided on the main body seat, and the rib plate is located between two adjustment slots 20. Two adjustment blocks 50 are inserted into the adjustment slots 20 at the same time and are clamped on both sides of the rib plate. Since the rib plate is an extension of the main body seat and the two adjustment slots 20 are opened on both sides of the rib plate, in this way, the sliding connection between the sliding cover 5 and the main body seat can be realized by the two adjustment blocks 50 clamping the rib plate. At the same time, the design of the adjustment slots 20 provides a sliding space for the sliding of the adjustment blocks 50, so that the sliding cover 5 can move linearly and be fitted on the main body seat.

[0039] Further, an adjustment protrusion 501 is provided on the adjustment block 50, and the shape of the adjustment protrusion 501 matches that of the elastic limit protrusion 25, so that when the adjustment block 50 slides along the rib plate, the distance between the adjustment protrusion 501 and the elastic limit protrusion 25 changes accordingly. Combining Figures 8 - 10 As can be seen, when the distance between the adjustment protrusion 501 and the elastic limit protrusion 25 becomes smaller, the adjustment protrusion 501 enters the reset vacancy of the elastic limit protrusion 25 and presses the elastic limit protrusion 25 outwards. At this time, the elastic limit protrusion 25 does not have the ability of elastic reset, so that the elastic limit protrusion 25 is completely stuck with the locking card slot 63 of the chopsticks 6 in the receiving hole, and the chopsticks 6 are blocked by the side limit posts 24 at the same time, that is, the chopsticks 6 are completely locked and limited in the length direction and cannot adjust the length; on the contrary, when the distance between the adjustment protrusion 501 and the elastic limit protrusion 25 becomes larger, the adjustment protrusion 501 moves away from the elastic limit protrusion 25, and the elastic limit protrusion 25 has a reset vacancy, so that the elastic limit protrusion 25 has the ability of elastic reset. The side limit posts 24 and the elastic limit protrusion 25 jointly elastically press the chopsticks 6 in the receiving hole, and the chopsticks 6 can move up and down in the receiving hole and the elastic limit protrusion 25 can always elastically engage in a locking card slot 63, so that the length of the chopsticks 6 below the main body seat can be adjusted.
