Description

Technical Field

[0001] This utility model relates to the field of drainer technology, and in particular to a bouncing device. Background Technology

[0002] Pop-up drains are a common type of drainage control device widely used in bathroom and kitchen appliances such as washbasins and kitchen sinks. Their core function is to open and close the drain outlet by pressing a stopper, combining convenience and aesthetics.

[0003] In existing technologies, to achieve the aforementioned functions, bouncing devices generally employ a highly integrated "drive rod-fixed base" structure. This highly integrated design faces significant challenges in actual production assembly: First, multiple precision components (such as the tracked drive rod, rolling elements, return elastic element, and housing) need to be aligned and fixed within extremely limited installation space, requiring high assembly precision and operator skill, thus impacting production efficiency and consistency. Therefore, the art needs a bouncing device with a more optimized structure and easier assembly. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a bouncing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bouncing device, comprising a drive rod and a fixed base, wherein the drive rod is movably inserted into the fixed base, a guide rail is provided on the outer circumferential surface of the drive rod, and a reset elastic element is provided inside the fixed base, wherein both ends of the reset elastic element abut against the lower end of the drive rod and the bottom wall of the inner cavity of the fixed base, respectively; it also includes a bouncing core, which is sleeved outside the fixed base, and a guide portion is provided on the bouncing core; a guide groove that mates with the guide portion is provided on the outer cylindrical surface of the fixed base; a radial through hole is provided on the side wall of the fixed base, and a rolling element is provided inside the radial through hole, the inner end of the rolling element extending into the guide rail of the drive rod; when the bouncing core is pressed and moves linearly along the guide groove, the rolling element drives the drive rod to rotate circumferentially relative to the fixed base and move axially.

[0006] By adding a spring core independent of the fixed base and drive rod, and transferring the pressing surface from the drive rod to the spring core, the external operating components and internal transmission components are structurally separated. The spring core and the fixed base are connected by a linear fit between the guide part and the guide groove, which not only ensures the stability of the pressing guidance, but also makes the assembly process of the whole device simpler. The internal precision transmission components (such as rolling elements and guide rails) can be assembled independently in the fixed base and then combined with the spring core.

[0007] As a preferred embodiment of this utility model, the upper part of the bouncing core is provided with an external thread section, and a bouncing cap is threadedly connected to the external thread section.

[0008] The above technical solution allows for the addition of a bouncing cap to the bouncing core via a threaded connection, enabling the external pressing surface to be designed and replaced independently.

[0009] As a preferred embodiment of this utility model, the bouncing cover and the upper part of the bouncing core form a sealed air cavity; the top or side wall of the bouncing core is provided with a vent hole, which connects the air cavity with the internal cavity of the bouncing core.

[0010] The above technical solution forms a sealed air cavity between the bouncy cover and the bouncy core, and connects it to the internal cavity of the bouncy core through a vent hole. This can effectively balance the internal air pressure changes during the pressing process, ensuring a smooth pressing action and consistent feel.

[0011] As a preferred embodiment of this utility model, the inner top wall of the bouncing core is constructed as a conical surface facing the drive rod, and the axis of the conical surface is coaxially arranged with the vent hole located at the top of the bouncing core; when the conical surface abuts against the upper end of the drive rod, a gap is formed around the vent hole in the abutment area between the two.

[0012] Through the above technical solution, the inner top wall of the bouncing core is set as a conical surface and is coaxial with the vent hole, which further optimizes the airflow path.

[0013] As a preferred embodiment of this utility model, the bouncing core has a notch on its cylindrical wall, and the guide portion includes a bent section formed in the notch and bent toward the guide groove of the fixed seat.

[0014] The above technical solution, by creating notches in the wall of the bouncing core and forming a bent guide, makes the guide fit more compact, which helps to improve motion stability.

[0015] As a preferred embodiment of this utility model, the guide rail on the drive rod is a heart-shaped guide rail, which has an upper positioning point and a lower positioning point; the drive rod has two stable working positions: when the rolling element is located at the upper positioning point, the drive rod is in a retracted state; when the rolling element is located at the lower positioning point, the drive rod is in an extended state.

[0016] The above technical solution, which uses a heart-shaped guide rail in conjunction with upper and lower positioning points, is a classic and reliable bistable transmission solution. It can ensure that the drive rod can switch accurately and stably between two working positions, while also having good tactile feedback and self-locking performance. It is suitable for a wide range of products such as push-button switches, pop-up pens, and drainers.

[0017] As a preferred embodiment of this utility model, the rolling element is a ball or a roller.

[0018] By using the above technical solution, the rolling element is specifically defined as a ball or roller, which can be easily installed in the radial through hole of the fixed seat, simplifying the assembly process and improving production assembly efficiency. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-6The illustrated bouncing device includes a drive rod 1 and a fixed base 2. The drive rod 1 is movably inserted into the fixed base 2. A guide rail 3 is provided on the outer circumferential surface of the drive rod 1. A reset elastic element 4 (preferably a reset spring) is provided inside the fixed base 2. The two ends of the reset elastic element 4 abut against the lower end of the drive rod 1 and the bottom wall of the inner cavity of the fixed base 2, respectively. The device also includes a bouncing core 5, which is sleeved on the outside of the fixed base 2. A guide portion 6 is provided on the bouncing core 5. A guide groove 7 that mates with the guide portion 6 is provided on the outer cylindrical surface of the fixed base 2. A radial through hole 8 is provided on the side wall of the fixed base 2. A rolling element 9 is provided in the radial through hole 8. The inner end of the rolling element 9 extends into the guide rail 3 of the drive rod 1. When the bouncing core 5 is pressed and moves linearly along the guide groove 7, the rolling element 9 drives the drive rod 1 to rotate circumferentially relative to the fixed base 2 and move axially.

[0024] In this embodiment, the rolling element 9 is a ball or roller, which can be easily installed in the radial through hole 8 of the fixed seat 2, simplifying the assembly process and improving production assembly efficiency. In this embodiment, the bottom of the fixed seat 2 is provided with a threaded section, which can be directly connected to the internal thread of the drain. In addition, the connection method between the fixed seat 2 and the drain is not limited to threaded connection, but can also be achieved by snap-fit, plug-in or adhesive.

[0025] like Figure 2 As shown, the bouncing device provided in this application is primarily used in bathroom drain systems. Through the cooperative structure of the bouncing core 5 and the bouncing cover 11, it effectively achieves stable pressing, smooth switching, and reliable sealing of the drain cover. Furthermore, due to its clear structure, simple assembly, and reliable motion transmission, this device is also suitable for push-button pens in the stationery industry, various electrical switches, and other products requiring linear-rotational composite motion and position holding, demonstrating good versatility and adaptability.

[0026] By adding a spring core 5 independent of the fixed base 2 and the drive rod 1, and transferring the pressing surface from the drive rod 1 to the spring core 5, the external operating components and the internal transmission components are structurally separated. The spring core 5 and the fixed base 2 are connected by the linear cooperation of the guide part 6 and the guide groove 7, which not only ensures the stability of the pressing guidance, but also makes the assembly process of the whole device simpler. The internal precision transmission components (such as the rolling element 9 and the guide rail 3) can be assembled independently in the fixed base 2 and then combined with the spring core 5.

[0027] The upper part of the bouncy core 5 is provided with an external thread section 10, and a bouncy cover 11 is threadedly connected to the external thread section 10. By adding the bouncy cover 11 to the bouncy core 5 through the threaded connection, the external pressing surface can be independently designed and replaced. In this embodiment, the connection method between the bouncy core 5 and the bouncy cover 11 is not limited to the threaded connection, but can also be achieved by snap-fit, plug-in or adhesive.

[0028] The bouncing cover 11 and the upper part of the bouncing core 5 enclose a sealed air cavity 12. A vent 13 is provided on the top or side wall of the bouncing core 5, connecting the air cavity 12 to the internal cavity of the bouncing core 5. The formation of a sealed air cavity 12 between the bouncing cover 11 and the bouncing core 5, and its connection to the internal cavity of the bouncing core 5 via the vent 13, effectively balances internal air pressure changes during pressing, ensuring smooth pressing action and consistent feel.

[0029] The inner top wall of the bouncing core 5 is constructed as a conical surface 14 facing the drive rod 1, and the axis of the conical surface 14 is coaxially arranged with the vent 13 located at the top of the bouncing core 5; when the conical surface 14 abuts against the upper end of the drive rod 1, a gap 15 is formed around the vent 13 in the abutment area between the two. This further optimizes the airflow path and facilitates gas flow.

[0030] The bouncing core 5 has a notch 16 on its cylindrical wall, and the guide portion 6 includes a bent section 17 formed within the notch 16 and bending towards the guide groove 7 of the fixing seat 2. By creating the notch 16 on the cylindrical wall of the bouncing core 5 and forming the bent guide portion 6, the guiding fit is made more compact, which helps to improve motion stability.

[0031] The guide rail 3 on the drive rod 1 is a heart-shaped guide rail, with an upper positioning point 18 and a lower positioning point 19. The drive rod 1 has two stable working positions: when the rolling element 9 is located at the upper positioning point 18, the drive rod 1 is in a retracted state; when the rolling element 9 is located at the lower positioning point 19, the drive rod 1 is in an extended state. The use of a heart-shaped guide rail in conjunction with the upper and lower positioning points 19 is a classic and reliable bistable transmission scheme, ensuring accurate and stable switching of the drive rod 1 between the two working positions. It also provides good tactile feedback and self-locking performance, making it suitable for a wide range of applications in push-button switches, pens, drainers, and other products.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
