Description

Technical Field

[0001] The utility model relates to the technical field of building bathroom devices, in particular to a silent bouncing core. Background Art

[0002] The push-type drainer belongs to the water drainage device for the sanitary table basin in buildings, and the bouncing core is one of the important components of the push-type drainer.

[0003] Most of the existing bouncing cores are of maze groove structure, and the reciprocating motion effect is realized through the cooperation of the maze groove and the hook. There are also a small number of bouncing cores adopting the structure of an old-fashioned ballpoint pen. During the use process, due to the interaction between parts, there is a relatively large sound during the opening and closing process. Especially when used in a quiet environment, the noise is relatively large, which affects normal rest. At present, although these two types of bouncing cores have relatively large sounds, they are widely used and well-verified in the market, resulting in the single reciprocating structure of the current bouncing core. It is difficult to achieve a silent effect, and a silent bouncing core is needed to meet the needs of such users. Summary of the Utility Model

[0051] The assembly process is as follows: the two rotating shafts 30 are respectively placed in the two rotating shaft grooves 22 of the screw shaft 20, and the truncated cone 31 falls into the truncated cone groove 23. The rotating shaft 30 can rotate freely, and then the guide blocks 32 of the rotating shaft 30 are respectively placed in the guide grooves 41 of the two guide groove blocks 40. After assembly, the two guide groove blocks 40 are placed in the two mounting grooves 12 of the housing 10 to achieve a limiting effect and prevent the parts from rotating. Then the spring 50 is placed in the screw shaft 20, and finally the base 60 is covered, and the buckle 61 falls into the buckle slot hole 13 to complete the assembly.

[0052] Working principle: Combined with Figure 16 As shown, the included angles between the two planes 32.1 of the guide block 32 and the right-angle turning surface 32.2 on one side are A1 and A2, and the included angles between the two planes 32.1 of the guide block 32 and the right-angle turning surface 32.2 on the other side are A3 and A4. Figure 14As shown in the figure, let the angle formed by side g41.7 and side h41.8 be angle 1, and the angle formed by side d41.4 and side e41.5 be angle 2.

[0053] 1. Closing process: The initial state is the open state. The state of the guide block 32 in the guide groove 41 is as shown in Figure 16 Step1 of the figure. The A1 and A2 angles of the guide block 32 are located above, and the right-angled turning surface 32.2 where they are located is in contact and fit with the sides a41.1 and b41.2 of the guide groove 41. Under the downward action, the contact point of the A4 angle of the guide block 32 and the side d of the guide groove 41 is B1, as shown in Figure 16 Step2 of the figure; The A4 angle of the guide block 32 slides along the side d41.4 of the guide groove 41. After the guide block 32 rotates by a certain angle, the A3 angle contacts the side e41.5 of the guide groove 41 and reaches stability at the lowest point. The contact point of the A3 angle and the side e41.5 is B2. At this time, the angle 2 of the guide groove 41 contacts the guide block 32, as shown in Figure 17 Step3 of the figure; After releasing, under the action of the spring 50 force, the guide block 32 moves upward, and the A1 contacts the side g41.7, as shown in Figure 17 Step4 of the figure, and the contact point is B3; The guide block 32 starts to rotate, the angle 1 of the guide groove 41 contacts the guide block 32. After the guide block 32 rotates by a certain angle, the A2 angle contacts the side h41.8, the contact point is B4, and the A4 angle contacts the side c41.3, the contact point is B5, forming a three-point stable state with angle 1. At this time, the bounce core is in the closed state, as shown in Figure 18 Step5 of the figure.

[0054] 2. Opening process: The initial state is the closed state, as shown in Figure 18 Step5 of the figure. Press the bounce core, and the guide block 32 moves downward to the state shown in Figure 18 Step6 of the figure. At this time, the side of the guide block 32 touches the angle 2 of the guide groove 41. Under the downward force and the action of angle 2, the guide block 32 rotates counterclockwise. After rotating by a certain angle, the A2 angle contacts the side e41.5, and the contact point is B6. At this time, the guide block 32 reaches a stable form under the restriction of B6 and angle 2, as shown in Figure 19 Step7 of the figure; After releasing, the guide block 32 moves upward under the action of the spring 50. During the movement, the side of the guide block 32 contacts the angle 1 of the guide groove 41, as shown in Figure 19 Step8 of the figure; The guide block 32 rotates counterclockwise under the action of angle 1 and the upward force until the plane 32.1 of the guide block 32 is horizontal with the side h41.8 of the guide groove 41, as shown in Figure 20 Step9 of the figure; Finally, the guide block 32 rises along the guide groove 41 to the highest point under the force of the spring 50. The A1 and A2 angles of the guide block 32 are located above, and the right-angled turning surface 32.2 where they are located is in contact and fit with the sides a41.1 and b41.2 of the guide groove 41, reaching the open state, as shown in Figure 20Step 10. By repeating this process, the opening and closing effects can be achieved. Since the state change is realized by the rotation of the guide block 32 under the action of the force of the spring 50 on the part, the collision between parts is reduced, thereby reducing the sound. Moreover, the change of the part is driven by the acting force during the pressing process, and the change process is linear, which can avoid the sound generated by the instantaneous change of the cooperation between parts and achieve the effect of silence.

[0055] The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. The present invention can be used on similar products, and any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
