Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water bag connector technology, specifically relating to a novel water-stop connector structure. Background Technology
[0002] Water bags or soft water bags are common water storage structures, and they all have corresponding connector structures. Conventional connector structures for water bags will allow water to flow directly when connected to water pipes, failing to effectively stop the water flow. Moreover, during use, residual water in the water pipe will flow out of the connector, causing the storage structure, such as a backpack, to get wet and affecting its normal use. Therefore, designing a connector that can achieve a water-stopping function is a technical problem that our technicians need to solve. Utility Model Content
[0003] The purpose of this utility model is to provide a novel water-stop joint structure, which aims to solve the above-mentioned technical deficiencies in the existing technology.
[0004] The technical solution to achieve the purpose of this utility model is a novel water-stop joint structure, including a female fastener connected to a water pipe and a male fastener connected to the female fastener. A water valve structure is provided inside the female fastener and the male fastener. The water valve structure includes a valve column, a sealing ring and a spring.
[0005] The valve stem has an outlet channel with an outer end opening inside. The valve stem has an annular sealing groove on its inner outer wall. The valve stem has several guide groove holes on its inner end outer wall that are connected to the outlet channel. The guide groove holes are located on the edge of the annular sealing groove near the outlet end.
[0006] The lower part of the inner wall of the female fastener's cavity is a frustum-shaped recessed area;
[0007] The sealing ring is fitted inside the annular sealing groove, and the spring is disposed between the end of the valve stem and the bottom wall of the inner cavity of the female fastener.
[0008] Under the action of the spring, the valve stem is sealed against the inner wall of the female fastener, at which time the female fastener is disconnected from the water outlet channel;
[0009] When the valve stem is compressed, the spring compresses, the sealing ring enters the frustum-shaped recessed area, and the female fastener connects to the water outlet channel.
[0010] A further preferred embodiment is that a limiting protrusion is integrally formed on the outer wall of the male fastener;
[0011] The outer diameter of the male fastener matches the inner diameter of the female fastener, the end of the male fastener is inserted into the inner cavity of the female fastener, and the limiting protrusion is attached to the end face of the female fastener and ultrasonically welded to fix it.
[0012] The outer diameter of the valve stem matches the inner diameter of the male fastener, and the outer end of the valve stem extends out of the end face of the male fastener under the action of the spring.
[0013] A further preferred embodiment is that the input end of the female fastener is integrally formed with a connecting cylinder, and the outer wall of the connecting cylinder is integrally formed with a plurality of annular locking teeth protrusions.
[0014] The connecting cylinder is inserted into the water pipe, and a sealed connection and positioning are achieved through an annular locking tooth protrusion.
[0015] A further preferred embodiment is that the male fastener, female fastener, and valve stem are all plastic or silicone structural components.
[0016] A further preferred embodiment is that the outer diameter of the sealing ring is larger than the inner diameter of the female fastener and smaller than the inner diameter of the frustum-shaped recessed area.
[0017] Compared with the prior art, the novel water-stop joint structure provided by this utility model has the following positive effects: The water valve structure of this utility model includes a valve column, a sealing ring, and a spring. Under the action of the spring, the valve column is sealed to the inner wall of the female fastener through the sealing ring, thus achieving water-stop operation. This can prevent water pipe leakage and avoid wetting the stored backpack. In use, pressing the valve column compresses the spring and connects the female fastener to the water outlet channel, thereby achieving water outlet control and improving the convenience and effectiveness of use. Moreover, the limiting protrusion is attached to the end face of the female fastener and ultrasonically welded to fix it, which can also improve the sealing performance of the overall structural connection, making it stable and reliable in use.

[0023] 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.
[0024] Example
[0025] See Figure 1 , Figure 2 and Figure 3 As shown, a novel water-stop joint structure includes a female fastener 1 connected to a water pipe and a male fastener 2 connected to the female fastener. A water valve structure 3 is provided within both the female and male fasteners. The water valve structure includes a valve stem 31, a sealing ring 32, and a spring 33. In this embodiment, the male fastener, female fastener, and valve stem are all plastic or silicone structural components. Specifically, they are food-grade plastic or silicone structural components, thereby improving safety during use.
[0026] like Figure 2 and Figure 3 As shown, the valve stem has an outlet channel 4 with an outer end opening. The valve stem has an annular sealing groove 5 on its inner outer wall. The valve stem also has several guide groove holes 6 connected to the outlet channel on its inner outer wall. The guide groove holes are located on the edge of the annular sealing groove near the outlet end. The guide groove holes are mainly used to guide the water in the female fastener to the outlet channel, thereby realizing the water outlet control operation. The lower part of the inner wall of the female fastener is a frustum-shaped recessed area. In actual application, the outer diameter of the sealing ring is larger than the inner diameter of the female fastener and smaller than the inner diameter of the frustum-shaped recessed area.
[0027] like Figure 2 As shown, during assembly, the sealing ring is fitted inside the annular sealing groove, and the spring is positioned between the end of the valve stem and the bottom wall of the inner cavity of the female fastener. Under the action of the spring, the sealing ring seals against the inner wall of the female fastener, at which point the female fastener is disconnected from the water outlet channel. When the valve stem is compressed, the spring compresses, and the sealing ring enters the frustum-shaped recessed area, connecting the female fastener to the water outlet channel. When not in use, the spring causes the valve stem to move outward, and the sealing ring abuts against the upper limit of the inner cavity of the female fastener while ensuring a seal. When an external force compresses the outer end of the valve stem, such as when the water outlet seat collides, the valve stem moves inward and compresses the spring. At the same time, the sealing ring enters the frustum-shaped recessed area, allowing water in the female fastener to move from the edge of the sealing ring and flow outward into the water guide groove.
[0028] like Figure 1 , Figure 2As shown, a limiting protrusion 7 is integrally formed on the outer wall of the male fastener; the outer diameter of the male fastener matches the inner diameter of the female fastener, and the end of the male fastener is inserted into the inner cavity of the female fastener. The limiting protrusion is fitted to the end face of the female fastener and ultrasonically welded for fixation; the outer diameter of the valve stem matches the inner diameter of the male fastener, and the outer end of the valve stem extends out of the end face of the male fastener under the action of the spring. Ultrasonic welding for fixation helps improve the sealing of the connection and prevents water leakage.
[0029] like Figure 1 and Figure 2 In this embodiment, the input end of the female fastener is integrally formed with a connecting cylinder 8, and the outer wall of the connecting cylinder is integrally formed with several annular locking teeth 9. During assembly, the connecting cylinder is inserted into the water pipe, and a sealed connection and positioning are achieved through the annular locking teeth. This improves the convenience of insertion into the water pipe and the sealing performance of the connection.
[0030] Compared with the prior art, the novel water-stop joint structure provided by this utility model has the following positive effects: The water valve structure of this utility model includes a valve column, a sealing ring, and a spring. Under the action of the spring, the valve column is sealed to the inner wall of the female fastener through the sealing ring, thus achieving water-stop operation. This can prevent water pipe leakage and avoid wetting the stored backpack. In use, pressing the valve column compresses the spring and connects the female fastener to the water outlet channel, thereby achieving water outlet control and improving the convenience and effectiveness of use. Moreover, the limiting protrusion is attached to the end face of the female fastener and ultrasonically welded to fix it, which can also improve the sealing performance of the overall structural connection, making it stable and reliable in use.
[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
