Description

Technical Field

[0001] The utility model relates to the technical field of pop-up cores of drainers, in particular to a universal drain pop-up core with a built-in water sealing function. Background Art

[0002] At present, the pop-up systems on the market are all designed for individual use scenarios, either for faucet washbasins alone, or for bathtubs alone, or with separate large and small face covers. There is no universal pop-up system that can adapt to different drainage requirements. This forces enterprises to produce multiple sizes of pop-up core system products simultaneously to meet the usage needs of different scenarios, increasing the variety of materials and inventory pressure, which is not conducive to intensive production, energy conservation, and emission reduction.

[0003] Moreover, the existing drainer products are assembled by combining a pop-up system with a sealed top cover or other devices. Frequent disassembly easily leads to failure, and cumulative deviation is likely to occur in the dimensional fit of multiple functional parts, resulting in poor sealing and easy leakage. At the same time, this design of multiple-part combination also limits the selection of materials and shapes of the drainer face cover.

[0004] In addition, in the design of existing pop-up core system products, when the product is in the open and closed states, due to the spring force not being centered, or the forces in the open and closed states not being centered and asymmetric, the product will have an axial angular offset in the open and closed states, resulting in poor appearance or sealing after assembly, thereby affecting the quality and aesthetics of the product itself. Moreover, in the existing pop-up core structure, during the opening and closing process, when pressing or popping open, the spring pressure directly acts on the hook, or there is a limit in the open and closed states but the limit is only on one side, and the force is uneven, which easily leads to the breakage of the hook. Also, due to the structural size limitation of the spring, the compression ratio is too large, and the spring is prone to failure. Considering the above factors, the service life of the pop-up core is ultimately affected. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the above-mentioned deficiencies by providing a universal drain pop-up core with a built-in water sealing function. By using the pop-up core core and the adapter head in combination, the universal pop-up core core can be used as a standard part in the factory. Only by matching a simple adapter head can it meet the different washbasin requirements of customers and the market, facilitating the factory to customize different face covers for customers and finally assemble them onto the universal pop-up system, without the need to redesign the entire pop-up drainer. At the same time, the sealing function of the face cover is liberated, and the face cover does not need to be assembled with a sealing gasket, making the processing simpler. This allows customers to make more shape and material adaptation choices for decoration, and also increases the selectivity of the flange design and size range of the drainer.

[0006] To achieve the above object, a general-purpose drainage bounce core with a built-in water sealing function is designed, which includes a bounce core core 9 and a bounce core adapter head 10. The bounce core core 9 and the bounce core adapter head 10 are installed as a whole. The bounce core adapter head 10 is provided with a sealing gasket 1. The bounce core core 9 includes a shaft core 4, a main body 5, a hook 6, a spring 7 and an upper cover 8. The main body 5 is of a cylindrical structure. The shaft core 4 is set as a cylindrical shape. The upper part of the shaft core 4 is placed inside the lower part of the main body 5. Both sides of the top end of the shaft core 4 are provided with limiting structures, and are connected with the inner wall of the main body 5 through the limiting structures to prevent slipping out of the main body 5. A cavity in the upper part of the shaft core 4 is internally provided with a spring 7. The upper end of the spring 7 is fixedly connected to the upper cover 8. The upper cover 8 is covered on the top end of the main body 5 and is fixedly connected to the main body 5 through a side buckle. An opening position at the top end of the upper cover 8 is provided with a hook 6. The hook 6 is located at the center inside the spring 7. The upper end of the hook 6 is connected to the upper cover 8 and fixed through a snap ring 2. The lower end of the hook 6 is in contact and cooperation with a track chute 4.1 inside the shaft core 4 under the locking force of the snap ring 2. The hook 6 moves downward along the track chute 4.1 under the action of a pressing force and completes the fixation at the closed position. After the hook 6 runs to the closed position, it is unlocked by pressing and returns to the open and closed position with the upper cover 8 under the action of the spring 7.

[0007] Further, the bounce core adapter head 10 includes an adapter head 3 and a sealing gasket 1. The sealing gasket 1 is installed on the periphery of the adapter head 3. The adapter head 3 and the bounce core core 9 are combined into a whole by an inverted buckle and strong pressure connection method. The bounce core adapter head 10 adapts to corresponding washbasins and drain fittings through adapter heads 3 of different shapes and heights. The bounce core adapter head 10 realizes water storage and drainage through the sealing gasket 1.

[0008] Further, the top of the adapter head 3 is provided with threads and is connected to the face cover through threads or thread conversion parts, greatly reducing the specifications of the face cover, and the face cover does not need to be assembled with a sealing gasket, and the processing is simpler.

[0009] Further, the bottom of the shaft core 4 is provided with external threads and is fixed to the flange of the drain fitting through the external threads. A step is provided in the track chute 4.1 inside the shaft core 4, and the step is used to prevent the hook 6 from retreating at the step position.

[0010] Further, a strip-shaped groove 5.1 extending axially is provided on the inner wall of the main body 5, and a strip-shaped protrusion 4.3 extending axially is provided on the outer wall of the shaft core 4. The strip-shaped protrusion 4.3 is connected and matched with the strip-shaped groove 5.1. The rotation between the main body 5 and the shaft core 4 is prevented through the strip-shaped groove 5.1 and the strip-shaped protrusion 4.3.

[0011] Further, symmetric limiting steps 5.2 are provided in the middle of the inner wall of the main body 5, and symmetric hanging platforms 4.2 for limiting are provided on both sides of the top end of the shaft core 4. The hanging platforms 4.2 are cooperatively connected with the limiting steps 5.2, and the axial movement range of the shaft core 4 is limited to prevent it from sliding out of the main body 5.

[0012] Further, a first snap protrusion 5.3 is provided on the outer wall of the top of the main body 5, and an inverted buckle rib 3.2 is provided on the inner wall of the adapter head 3. The inverted buckle rib 3.2 is cooperatively connected with the first snap protrusion 5.3. The main body 5 and the adapter head 3 are integrally formed by strong reverse buckling through the inverted buckle rib 3.2 and the first snap protrusion 5.3. Through this strong reverse buckling structure, the main body 5 and the adapter head 3 can be stably connected and cannot be disassembled at the same time.

[0013] Further, a limiting rib 5.4 extending axially is provided on the outer wall of the main body 5, and a limiting groove 3.1 extending axially is provided on the inner wall of the adapter head 3. The limiting groove 3.1 is cooperatively connected with the limiting rib 5.4. The limiting groove 3.1 and the limiting rib 5.4 are used to prevent the adapter head 3 and the main body 5 from rotating after assembly.

[0014] Further, snap fasteners 8.1 extending downward are provided on both the left and right sides at the bottom end of the upper cover 8, and a second snap protrusion 5.5 recessed inward is provided on the outer wall of the top of the main body 5. The snap fasteners 8.1 are embedded in the second snap protrusions 5.5. The upper cover 8 and the main body 5 are assembled into one body through the snap fasteners 8.1 and the second snap protrusions 5.5. At the same time, the spring 7 can be pre-pressed so that the core of the bouncing core can be integrated, thereby further improving the overall strength after being assembled with the adapter head.

[0015] Further, the adapter head 3, the shaft core 4, the main body 5 and the upper cover 8 are all injection molded with plastic parts, so the cost is low and it is convenient for large-scale production; the snap ring 2 and the hook 6 are both made of stainless steel material, which not only has a low cost, but also has good corrosion resistance.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] (1) The application scenarios of the present utility model are extensive. In addition to being applicable to existing faucet washbasins, it can also be applied to bidets, bathtub drains, shower rooms, and kitchen drains, etc. It is integrated and universal, with wide applicability.

[0018] (2) The present utility model arranges the spring in the center of the bouncing core and arranges the hook in the center of the spring. This central spring layout can extend the service life of the spring and the entire product. At the same time, due to the uniform central force, the central stability of the product is better.

[0019] (3) Through optimized design, the track chute of the present utility model can be entirely placed inside the spring, effectively increasing the length of the spring after compression, reducing the compression ratio of the spring, and increasing the service life of the spring.

[0020] (4) Through optimized design, even when the spring is arranged at the center of the bouncing core, the shaft core can still contact the upper cover in the compressed state, maximizing the axial guiding length, effectively enhancing the sliding fit length between the shaft core and the main body, increasing the guiding stability, making the pressing smoother, and having a higher central stability.

[0021] (5) The threaded connection structure between the bouncing core of the present utility model and the product allows users to easily disassemble the face cover or remove the bouncing core, facilitating cleaning. Moreover, repeated disassembly does not affect the use of the product itself. At the same time, the thread of the bouncing core connected to the drain flange of the present utility model can select metal inserts as needed to prevent damage to the thread caused by multiple disassembly.

[0022] (6) Through different-sized adapter heads, the present utility model realizes that the closing height of the lid can be adjusted, and the face cover can be as close as possible to the ceramic washbasin or metal basin, being more aesthetically pleasing and not affecting the use function. At the same time, through optimized design of the product diameter, the reduced outer diameter can achieve a larger water flow rate.

[0023] (7) The present utility model liberates the sealing function of the lid, allowing for more choices of shapes and materials for decoration. At the same time, it also increases more selectivity for the flange design and size range of the drain. Moreover, the bouncing opening and closing of the product during operation are smoother and softer, with a clear and pleasant sound effect, enhancing the customer's comfort experience.

[0024] (8) When the bouncing core of the present utility model is in the opening and closing state and the spring opens, by adding symmetric physical limits on both sides of the plastic part, the acting force of the spring can be prevented from acting on the metal hook, reducing the fatigue stress of the metal hook and increasing the service life of the product.

[0025] (9) The metal hook of the present utility model is arranged at the center of the product, thus ensuring that the force application point is at the center of the product in the closed state. At the same time, the spring is also stressed at the center, enabling the product to maintain central verticality in the closed state, increasing the aesthetic degree and sealing accuracy of the product. At the same time, when the product is in the closed state and pressed to unlock, the unlocking gap is smaller and more precise compared to the product with the previous design, and the sealing performance is better.

[0026] (10) In the combination of the bouncing core and the adapter head of the present utility model, the adapter head can have different shapes and heights. After being assembled to the universal bouncing core, it can be adapted to various types and sizes of faucet basins, bidet basins, bathtubs, shower rooms, and kitchen sinks on the market.

[0027] (11) The utility model can extend different product platforms from a single bouncing core and different bouncing core adaptors. Each product platform can be applicable to different face covers. The connection dimensions of all face covers and adaptors are the same, and all face covers can be assembled into different product series, greatly reducing the warehouse space of the factory.

[0028] (12) The prominent advantage of the general bouncing core and adaptor design of the utility model is that the core of the bouncing core can be used as a standard part in the factory. Only a simple adaptor needs to be designed to meet different washbasin requirements of customers and in the market, which is convenient for the factory to customize different face covers for customers and finally assemble them onto a general bouncing system without the need to redesign the whole bouncing drainer.

[Specific implementation method]

[0054] As shown in the appendix Figure 1 to the appendix Figure 12 As shown, the utility model provides a universal drainage bounce core with a water sealing function, which includes a bounce core core 9 and a bounce core adapter head 10. The bounce core core 9 and the bounce core adapter head 10 are installed as a whole. The bounce core adapter head 10 is provided with a sealing gasket 1. The bounce core core 9 includes a shaft core 4, a main body 5, a hook 6, a spring 7 and an upper cover 8. The main body 5 is a cylindrical structure. The shaft core 4 is set as a cylindrical shape. The upper part of the shaft core 4 is placed inside the lower part of the main body 5. Both sides of the top of the shaft core 4 are provided with limiting structures, and are connected with the inner wall of the main body 5 through the limiting structures to prevent slipping out of the main body 5. A cavity in the upper part of the shaft core 4 is provided with a spring 7. The upper end of the spring 7 is fixedly connected to the upper cover 8. The upper cover 8 is covered on the top of the main body 5 and is fixedly connected to the main body 5 through side buckles. An opening position at the top of the upper cover 8 is provided with a hook 6. The hook 6 is located at the center inside the spring 7. The upper end of the hook 6 is connected to the upper cover 8 and fixed by a snap ring 2. The lower end of the hook 6 contacts and cooperates with a track chute 4.1 inside the shaft core 4 under the locking force of the snap ring 2. The hook 6 moves downward along the track chute 4.1 under the action of a pressing force and completes the fixation at the closed position. After the hook 6 runs to the closed position, it is unlocked by pressing and returns to the open and closed position with the upper cover 8 under the action of the spring 7.

[0055] Among them, the bounce core adapter head 10 includes an adapter head 3 and a sealing gasket 1. The sealing gasket 1 is installed on the periphery of the adapter head 3. The adapter head 3 and the bounce core core 9 are combined as a whole by an inverted buckle and strong pressure connection method. The bounce core adapter head 10 adapts to corresponding washbasins and drain fittings through adapter heads 3 with different shapes and heights. The bounce core adapter head 10 realizes water storage and drainage through the sealing gasket 1. The top of the adapter head 3 is provided with threads and is connected to the face cover through the threads or thread conversion parts. That is, the adapter head 3 can be connected to the face cover through external threads, can also be connected to the face cover through internal threads, and can also be connected to the face cover through internal threads and thread conversion parts, greatly reducing the specifications of the face cover, and the face cover does not need to be assembled with a sealing gasket, and the processing is simpler.

[0056] A strip-shaped groove 5.1 extending axially is provided on the inner wall of the main body 5, and a strip-shaped protrusion 4.3 extending axially is provided on the outer wall of the shaft core 4. The strip-shaped protrusion 4.3 is connected in cooperation with the strip-shaped groove 5.1. The rotation between the main body 5 and the shaft core 4 is prevented by the strip-shaped groove 5.1 and the strip-shaped protrusion 4.3; on the middle part of the inner wall of the main body 5, there are symmetrically arranged limiting steps 5.2 on the left and right. On both sides of the top end of the shaft core 4, there are symmetrically arranged hanging platforms 4.2 for limiting. The hanging platforms 4.2 are connected in cooperation with the limiting steps 5.2, and the axial movement range of the shaft core 4 is limited to prevent it from sliding out of the main body 5; on the outer wall of the top of the main body 5, there is a snap protrusion one 5.3, and on the inner wall of the adapter head 3, there is an inverted buckle rib 3.2. The inverted buckle rib 3.2 is connected in cooperation with the snap protrusion one 5.3. The main body 5 and the adapter head 3 are integrally formed by strong snap buckling through the inverted buckle rib 3.2 and the snap protrusion one 5.3. Through this strong snap buckling structure, the main body 5 and the adapter head 3 can be stably connected and cannot be disassembled at the same time; on the outer wall of the main body 5, there is a limiting rib 5.4 extending axially, and on the inner wall of the adapter head 3, there is a limiting groove 3.1 extending axially. The limiting groove 3.1 is connected in cooperation with the limiting rib 5.4. The limiting groove 3.1 and the limiting rib 5.4 are used to prevent the adapter head 3 and the main body 5 from rotating after assembly.

[0057] External threads are provided at the bottom of the shaft core 4 and are fixed to the drain flange through the external threads. There is a step in the track chute 4.1 inside the shaft core 4, and the step is used to prevent the hook 6 from retracting at the step position. On the left and right sides at the bottom end of the upper cover 8, there are downwardly extending snaps 8.1. On the outer wall of the top of the main body 5, there are inwardly recessed snap protrusions two 5.5. The snaps 8.1 are embedded in the snap protrusions two 5.5. The upper cover 8 and the main body 5 are assembled into one through the snaps 8.1 and the snap protrusions two 5.5. At the same time, the pre-compressed spring 7 can be used to make the bounce core integrated, so that the overall strength is further improved after being assembled with the adapter head. The adapter head 3, the shaft core 4, the main body 5, and the upper cover 8 are all made by plastic injection molding, with low cost and convenient for large-scale production; the snap ring 2 and the hook 6 are both made of stainless steel. Compared with the brass materials on the market, not only the cost is low, but also it has good corrosion resistance.

[0058] The utility model designs a bounce core that can be used in multiple scenarios for different usage occasions. It has an opening and closing function. By pressing, the product can be maintained in two different states of opening and closing. When applied to drainage components, it can realize the functions of water storage and drainage. The bounce core mainly includes a sealing gasket 1, a snap ring 2, an adapter head 3, a shaft core 4, a main body 5, a hook 6, a spring 7, and an upper cover 8. The shaft core 4 is inserted into the upper end of the main body 5. Through the limits on both sides of the shaft core 4, the shaft core 4 is prevented from sliding out of the main body 5. The spring 7 is placed on the shaft core 4. The upper cover 8 fixes the upper end of the spring 7. After compressing the spring 7, the upper cover 8 and the main body 5 are connected and fixed through side buckles. Then, the hook 7 is assembled from the opening position at the top end of the upper cover 8. The upper end of the hook 7 is connected to the upper cover 8 and fixed through the snap ring 2. The lower end of the hook 7 contacts and cooperates with the track chute of the shaft core 7 under the locking force of the snap ring 2. Through pressing and the elastic force of the spring 7, the opening and closing function of the whole product is realized. At this time, the core 9 of the general bounce core is assembled. After the sealing gasket 1 and the adapter head 3 are assembled, they are connected to the core 9 of the bounce core through an inverted buckle and strong pressure connection method, that is, an integrated sealed bounce core with a sealing gasket is formed.

[0059] In the design of the adapter head of the utility model, the top side of the adapter head is completely closed, and the sealing gasket is assembled on the adapter head. After being assembled with the core of the bounce core, the bounce core itself has a sealing function, that is, the functions of water storage and drainage can be realized without a face cover. Therefore, the bounce system can use face covers of different materials, shapes, and sizes. Since the face cover itself is only used for surface decoration, there is no need to consider the dimensional tolerance of the face cover itself and the machining of the sealing position, so there are more choices of materials, shapes, and sizes.

[0060] The utility model can extend different product platforms from a single bounce core core, combined with different bounce core adapter heads. At the same time, the threaded connections of all adapter heads and lids use the same thread, or through additional adapters, each product platform can be applicable to different face covers, and the connection dimensions of all face covers and adapter heads are the same. Therefore, all face covers can be assembled onto different product series, thus greatly reducing the production and inventory pressure of the factory.

[0061] The following further describes the utility model in conjunction with the attached drawings and specific embodiments:

[0062] As shown in the attached Figure 2 to the attached Figure 12As shown, the universal spring core includes a shaft core 4 fixed to a flange. A track groove 4.1 within the shaft core 4 cooperates with a hook 6 to secure the product in the closed position. The tightening force generated by the contraction of the retaining ring 2 restricts the hook 6, whose end in contact with the track groove 4.1, to the track groove 4.1. Furthermore, the different steps within the track groove 4.1 prevent the hook 6 from retreating from the stepped position within the track. When the hook reaches the closed position, pressing it unlocks the hook from the closed position and, under the action of the spring, returns it to the open position, ultimately completing a closed stroke. The contact area between the hook 6 and the track groove 4.1 is very small, effectively reducing noise during system operation. The main body 5 is fixed on the outside of the product, and the strip groove 5.1 on the main body 5 can prevent the rotation between the main body 5 and the shaft core 4. At the same time, the limiting step 5.2 and the hanging platform 4.2 are used in conjunction with each other, so that the shaft core can only move along the axial direction of the main body 5, and the design of the limiting step 5.2 and the hanging platform 4.2 can play a role in movement limitation. The left-right symmetrical design of the limiting step 5.2 and the hanging platform 4.2 also makes the product more stable in the opening and closing state; after the product is fixed on the upper cover 8, the shaft core 4 can only move axially in the internal space formed by the upper cover 8 and the main body 5 and will not fall out, which means that when the product is in the opening and closing state, the spring force will not act on the hook 6, thereby reducing the fatigue stress of the hook 6.

[0063] The main body 5 and the adapter head 3 are used together. The snap-on protrusion 5.3 on the main body 5 cooperates with the inverted rib 3.2 on the adapter head 3. This strong pressure inverted structure can make the two parts stably connected and inseparable; at the same time, the limiting protrusion 5.4 can be used in conjunction with the limiting groove 3.1 on the adapter head to prevent the adapter head 3 and the main body 5 from rotating after assembly, so as to ensure that the spring core can be unscrewed from the drain flange. The adapter head 3 can have different shapes and sizes to meet the needs of basins and flanges of different sizes; sealing gaskets 1 of different sizes are installed on the adapter head 3, and different adapter heads are used to meet the needs of different basin and drain sizes.

[0064] The upper cover 8 secures the upper end of the spring and the upper end of the hook 6, ensuring that the hook 6 moves within the fixed track. The upper cover is connected to the main body's latch protrusion 5.5 via a latch 8.1, preloading the spring 7 and integrating the spring core. When assembled with the adapter, the overall strength is further enhanced. The spring 7 is placed outside the track slot 4.1, allowing for a larger outer dimension. Its placement in the center of the product makes the spring system more stable during operation and effectively reduces side-to-side motion. The larger diameter of the spring increases its lifespan and provides greater elasticity, allowing the system to be used in larger water storage applications.

[0065] As attached Figure 13 and attached Figure 14As shown, the utility model adopts a universal spring core 9 and different adapter heads for use. The adapter heads can have different shapes and heights. After being assembled with the universal spring core 9, they can adapt to various types and sizes of faucets, basins, bidets, bathtubs, shower rooms, kitchen sinks, etc.

[0066] Since most of the pop-up systems currently available on the market are designed for specific usage scenarios, such as faucet basins, bathtubs, or large and small covers, they are not universal and cannot be adapted to different basin pop-up systems. However, the design of the universal pop-up core and adapter head of the utility model has a significant advantage. The pop-up core can be used as a standard part of the factory, and only a simple adapter head needs to be designed to meet the different basin needs of customers and the market. It also makes it convenient for factories to customize different covers for customers, and ultimately equip them with a universal pop-up system, without having to redesign the entire pop-up drain.

[0067] As attached Figure 15-1 , Attachment Figure 15-2 , Attachment Figure 15-3 and attached Figure 15-4 As shown in the figure, the spring core is used with a small adapter head and is suitable for spring drains with small covers. Figure 16-1 , Attachment Figure 16-2 and attached Figure 16-3 As shown, the spring core is used with a slightly larger adapter head, which is suitable for the spring drain of the bathtub. It can be seen that the spring core is the same, just need to be equipped with different adapter heads.

[0068] The utility model can be applied to large-cover basin drain, small-cover basin drain and bathtub drain respectively through different adapter heads, and the thread gauges of all large covers are consistent and interchangeable, and the adapter head of the small cover can be changed by adding a thread conversion piece, such as the attached Figure 17-1 and attached Figure 17-2 As shown in the figure, it is also suitable for all large covers, greatly reducing the specifications of the cover, and the cover does not need to be assembled with a sealing gasket, which is simple to process. Figure 18 The figure shows the effect after assembly. Through the adapter head, the ceramic cover, large bounce metal cover and small bounce cover can be used respectively. The ceramic cover and large bounce metal cover can be fully matched with the attached Figure 13 and attached Figure 14 The spring core after the adapter head is assembled is shown.
