Abstract
Description
Technical Field
[0001] This utility model relates to the field of separation valve equipment technology, and in particular to a leak-proof separation valve plug with a rubber ring to prevent detachment. Background Technology
[0002] After the adipose tissue is cut and filtered, centrifugation and oil-liquid separation are required. The separation valve is often used to control the opening and closing of the liquid outlet at the tip of the rubber stopper.
[0003] In the prior art, some rubber stopper separation valves adopt a structure with a metal block, which achieves sealing and flow control through the metal pad. However, this structure has the following drawbacks: the manufacturing process is complicated, requiring additional processing and assembly of the metal pad; the use of the metal pad increases material costs; and during disassembly and assembly, due to the rigid fit of the metal parts, the required torsional force is large, resulting in inconvenient operation.
[0004] Therefore, there is an urgent need for a simplified, lower-cost, and easier-to-assemble / disassemble separator valve plug structure. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a leak-proof rubber stopper for a separation valve with a rubber ring that prevents detachment. By sliding the locking block within the adjusting groove and the snap-fit groove, the push rod mechanism and the rubber stopper mechanism are connected, while the flow channels one and two are controlled. Furthermore, the design of the rail groove allows for quick assembly and disassembly of the push rod mechanism and the rubber stopper mechanism. Compared to traditional separation valves with metal blocks, this invention significantly simplifies the manufacturing process, reduces costs, decreases the torsional force required for assembly and disassembly, and improves operational convenience.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof rubber stopper for a rubber ring that prevents detachment, comprising a push rod mechanism, wherein the push rod mechanism is detachably connected to the rubber stopper mechanism; The push rod mechanism includes a push rod body with a fitting head at one end, and a flow channel is provided on the fitting head; The stopper mechanism includes a stopper body, and a second flow channel is provided at the bottom of the stopper body. The port position of the second flow channel corresponds to the port position of the first flow channel.
[0007] In a preferred embodiment, the sidewall of the fitting head is provided with a snap-fit block.
[0008] In a preferred embodiment, a groove is formed on the inner wall of the rubber stopper body, and a snap-fit direction mark is provided on the rubber stopper body corresponding to the port of the groove. The end of the groove away from the snap-fit direction mark is connected to a snap-fit groove, and the snap-fit groove is connected to an adjustment groove. Both the adjustment groove and the snap-fit groove are formed on the inner wall of the rubber stopper body.
[0009] In a preferred embodiment, when the push rod body is inserted into the rubber stopper body, the locking block slides into the rail groove, and after the locking block reaches the bottom of the rail groove, the rubber stopper body is rotated to make the locking block slide into the snap-fit groove, thus connecting the push rod body and the rubber stopper body.
[0010] In a preferred embodiment, when the snap-fit block slides into the adjustment groove, the first flow channel and the second flow channel are connected.
[0011] In a preferred embodiment, a rubber ring is fitted onto the outer wall of the rubber stopper body.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model achieves the connection between the push rod mechanism and the rubber stopper mechanism by sliding the snap-fit block in the adjustment groove and the snap-fit groove, while controlling the opening and closing of the flow channel one and the flow channel two. Furthermore, the design of the rail groove allows the push rod mechanism and the rubber stopper mechanism to be quickly disassembled and assembled. Compared with the traditional separation valve with metal block, it significantly simplifies the manufacturing process, reduces costs, and reduces the torsional force required for disassembly and assembly, thereby improving the ease of operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0019] like Figures 1 to 4 As shown, this utility model provides a technical solution: a leak-proof rubber stopper for a rubber ring that prevents detachment, including a push rod mechanism 1. The push rod mechanism 1 includes a push rod body 11 with a fitting head 12 at one end, and a flow channel 13 is provided on the fitting head 12. The push rod mechanism 1 is detachably connected to the rubber stopper mechanism 2. The rubber stopper mechanism 2 includes a rubber stopper body 21. A rubber ring 26 is fitted on the outer wall of the rubber stopper body 21. A flow channel 27 is opened at the bottom of the rubber stopper body 21. The port position of the flow channel 27 corresponds to the port position of the flow channel 13. In the above description, the push rod mechanism 1 and the rubber stopper mechanism 2 work together through a sophisticated mechanical structure to achieve controllable flow control and leak-proof sealing of the fluid. The fitting head 12 at the front end of the push rod body 11 in the push rod mechanism 1 serves as a connection and seal, and the flow channel 13 on the push rod body 11 allows the fluid to pass through. The rubber stopper body 21 of the rubber stopper mechanism 2 serves as a fixed base and a carrier for the flow channel 27. The rubber ring 26 on the outer wall of the rubber stopper body 21 is responsible for forming a static seal with the external system to prevent leakage. The flow channel 27 at the bottom of the rubber stopper body 21 connects with the flow channel. The port positions of 13 form a spatial correspondence, which allows the ports of the two flow channels to be precisely aligned and connected when the push rod mechanism 1 is inserted and rotated to a specific working position, and to be cut off otherwise. This design realizes complex valve functions through structural design, which not only completely avoids the high cost, complex process and laborious operation problems brought about by the traditional metal pad solution, but also ensures reliable sealing by relying on the rubber ring 26. At the same time, the modular detachable connection greatly facilitates maintenance and replacement. Overall, it achieves structural simplification, significant cost reduction and improved operating experience. The fitting head 12 has a snap-fit block 14 on its side wall, and the inner wall of the rubber stopper body 21 has a rail groove 22. The rubber stopper body 21 corresponding to the port of the rail groove 22 has a snap-fit direction mark 23. The end of the rail groove 22 away from the snap-fit direction mark 23 is connected to a snap-fit groove 25. The snap-fit groove 25 is connected to an adjustment groove 24. Both the adjustment groove 24 and the snap-fit groove 25 are opened on the inner wall of the rubber stopper body 21. In the above description, the mechanical interaction between the snap-fit block 14 on the side wall of the fitting head 12 and the rail groove 22, snap-fit groove 25, and adjustment groove 24 on the inner wall of the rubber stopper body 21 constitutes a quick connection and flow channel control function. The rail groove 22 provides an axial guide path for the insertion of the snap-fit block 14, ensuring that the push rod mechanism 1 can be initially positioned. The snap-fit direction indicator 23 provides clear operation guidance for the user to prevent misoperation. When the snap-fit block 14 reaches the bottom along the rail groove 22, the user can rotate the push rod mechanism 1 by pointing along the snap-fit direction indicator 23, so that the snap-fit block 14 can slide into the bottom of the snap-fit groove 25 that is connected to it, thus achieving a firm lock between the two. When the flow channel 13 and flow channel 27 are in a misaligned state, the existence of the adjustment groove 24 provides the receiving space of the snap block 14 for the connection between flow channel 13 and flow channel 27. This design allows the user to reliably switch between the two functional states of "connection lock-flow channel closed" and "connection lock-flow channel open" by simple rotation. The adjustment groove 24 serves as the final positioning groove for the flow channel opening, ensuring the consistency, stability and sealing of the flow channel connection state after each operation. Furthermore, the design achieved through the structural cooperation of the plastic parts themselves greatly improves the intuitiveness, reliability and economy of this utility model in use. Furthermore, when the push rod body 11 is inserted into the rubber stopper body 21, the locking block 14 slides into the rail groove 22, ensuring the initial alignment and guidance of the components. After the locking block 14 reaches the bottom of the rail groove 22, the rubber stopper body 21 is rotated to make the locking block 14 slide into the snap-lock groove 25. At this time, the locking structure of the snap-lock groove 25 will restrict the axial movement of the push rod mechanism 1, thereby achieving a firm connection between the push rod body 11 and the rubber stopper body 21. Even if the push rod body 11 is connected to the rubber stopper body 21, in this state, the flow channel 13 and the flow channel 27 are usually in a misaligned closed state. When the locking block 14 slides into the adjustment groove 24, the flow channel 13 and the flow channel 27 are connected. In the above description, the movement trajectory of the locking block 14 on the fitting head 12 in the track groove 22, the snap-fit groove 25 and the adjustment groove 24 on the inner wall of the rubber stopper body 21 is controlled by the two combined actions of axial insertion and circumferential rotation of the push rod body 11. This achieves reliable control of mechanical connection and fluid flow. This design allows users to achieve the function of closing and opening the flow channel by simply "inserting it to the bottom - rotating to lock - continuing to rotate to open" while ensuring that the push rod mechanism 1 and the rubber stopper mechanism 2 are always connected.
[0020] In this embodiment, the push rod body 11 and its front end are provided with a fitting head 12 with a flow channel 13. The core of the rubber stopper mechanism 2 is the rubber stopper body 21, which is provided with a flow channel 27 and an external sealing ring 26. The two are detachably connected by the engagement of the snap-fit block 14 on the side wall of the fitting head 12 with the rail groove 22, snap-fit groove 25 and adjustment groove 24 opened on the inner wall of the rubber stopper body 21. During assembly, the push rod body 11 is first inserted axially into the rubber stopper body 21, so that the snap-fit block 14 slides along the rail groove 22 as a guide path until it reaches the bottom. At this time, the snap-fit direction mark 23 at the port of the rubber stopper body 21 guides the user to rotate the push rod mechanism 1 or the rubber stopper mechanism 2 to engage the snap-fit block 14. The push rod body 11 is pushed into the bottom of the horizontally connected snap-fit groove 25 to lock it in place. At this time, the push rod body 11 is firmly connected to the rubber stopper body 21, but the flow channel 13 and the flow channel 27 are disconnected due to port misalignment. When it is necessary to connect the fluid, the user rotates the push rod mechanism 1 or the rubber stopper mechanism 2 in the opposite direction of the snap-fit direction indicator 23 to drive the snap-fit block 14 to slide out of the snap-fit groove 25 and finally enter the adjustment groove 24, so that the port of the flow channel 13 on the fitting head 12 is completely aligned with the port of the flow channel 27 at the bottom of the rubber stopper body 21, thereby connecting the flow channel 13 and the flow channel 27. At the same time, the rubber ring 26 on the outer wall of the rubber stopper body 21 always ensures a static seal with the external interface.
[0021] Working principle: like Figures 1 to 4 As shown, during assembly, the push rod body 11 is first inserted into the rubber stopper body 21, and the position of the locking block 14 is adjusted by rotating the push rod body 11 so that the locking block 14 is aligned with the rail groove 22. Then, the push rod body 11 is inserted into the rubber stopper body 21 so that the locking block 14 reaches the bottom of the rail groove 22 and enters the buckling groove 25. Then, the push rod body 11 is rotated along the direction of the buckling direction indicator 23 so that the locking block 14 slides into the bottom of the buckling groove 25, thus completing the connection between the push rod body 11 and the rubber stopper body 21, that is, completing the connection between the push rod mechanism 1 and the rubber stopper mechanism 2. When it is necessary to connect flow channel 13 and flow channel 27, simply rotate the push rod body 11 in the opposite direction of the snap-fit direction indicator 23 to make the snap-fit block 14 slide into the rubber ring 26, and the flow channel 13 and flow channel 27 can be connected.
[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
