Description

Technical Field

[0001] This utility model relates to the field of water pump accessories technology, specifically to a multi-purpose water pump connector. Background Technology

[0002] Water pumps are widely used in various fields such as industry, agriculture, construction, and households, and are essential equipment for transporting liquids. In practical applications, due to the different outlet specifications and pipe interface specifications of water pumps produced by different manufacturers, compatibility problems often arise when connecting water pumps and pipes. Currently, the common solution on the market is to use special couplings for specific water pump models. This method not only increases the cost of use, but also requires the purchase of new, compatible couplings when replacing water pumps or pipes of different specifications.

[0003] Traditional water pump couplings have the following main problems: First, they have a narrow range of applications, usually only suitable for one or a few specifications of water pumps and pipes; second, they have poor sealing performance, and are prone to leakage after long-term use; third, they have insufficient connection strength, and are prone to falling off under high-pressure working environments; and fourth, they are inconvenient to install and disassemble, requiring special tools to complete the operation.

[0004] Therefore, there is an urgent need for a multi-purpose pump coupling that can adapt to various specifications of pumps and pipes, has good sealing performance, a firm connection, and is easy to operate, in order to meet the connection needs of pump systems in different scenarios. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-purpose water pump coupling to solve the technical problems of narrow application range, poor sealing performance, insufficient connection strength and inconvenient operation of existing water pump couplings.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A multi-purpose water pump connector includes: a connector body, a conversion interface group, a sealing system, and an adaptive locking mechanism; wherein, the connector body is a hollow structure with a fluid channel formed inside; the conversion interface group is disposed at both ends of the connector body, including at least three different standard interfaces, which can be matched and connected to the outlet or inlet pipe of different models of water pumps respectively; the sealing system includes a double-layer sealing structure disposed inside each standard interface, the double-layer sealing structure including an inner deformable elastomer sealing ring and an outer pressure-responsive liquid sealant; the adaptive locking mechanism includes multiple elastic claws distributed on the outer periphery of the connector body and micro guide grooves that cooperate with the elastic claws.

[0009] Preferably, the deformable elastomer sealing ring is made of silicone rubber and has a composite curved surface structure with multiple micro elastic protrusions on the inner side.

[0010] Preferably, the pressure-responsive liquid sealant is encapsulated in an annular cavity inside the connector body and communicates with the interface connection through a microchannel. When the interface is connected, the pressure generated can cause the liquid sealant to flow out and form an auxiliary sealing layer.

[0011] Preferably, the elastic claw includes a main body and a locking part. The main body is hinged to the main body of the connector. The locking part has an arc-shaped structure and a first anti-slip texture on the inner side, and an operating protrusion on the outer side.

[0014] The multi-purpose water pump connector of this utility model has the following beneficial effects: This invention, by setting up various standard interfaces of different specifications, can be adapted to most models of water pumps and pipelines on the market, solving the problem of the narrow applicability of traditional connectors. It adopts an innovative double-layer sealing structure; the inner deformable elastomer sealing ring can adapt to different interface shapes, while the outer pressure-responsive liquid sealant can automatically adjust the sealing effect according to the working pressure, effectively preventing leakage.

Detailed Implementation

[0017] 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.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a multi-purpose water pump connector, including a connector body 1, a conversion interface group 2, a sealing system 3, and an adaptive locking mechanism 4.

[0019] The connector body 1 has a hollow structure with a fluid channel 11 formed inside. The fluid channel 11 adopts a gradient channel structure design, with the channel diameter smoothly transitioning from one end to the other, reducing resistance loss when the fluid passes through. The inner wall of the fluid channel 11 is provided with a spiral guide texture 12, which can reduce fluid turbulence, reduce noise, and improve fluid transmission efficiency. The surface of the connector body 1 is provided with a second anti-slip texture 13 for easy gripping by the operator. The connector body 1 is made of a corrosion-resistant and high-temperature resistant composite material, such as a composite material of polyetheretherketone (PEEK) and glass fiber, which has excellent mechanical properties, chemical corrosion resistance, and high-temperature resistance. The interior of the connector body 1 is also filled with a heat insulation material 14 to prevent the outer surface temperature from becoming too high and causing operational risks when conveying high-temperature fluids.

[0020] The adapter interface group 2 is located at both ends of the connector body 1 and includes various standard interfaces of different specifications. In this embodiment, the adapter interface group 2 includes a quick-connect internal thread interface 21, a quick-connect external thread interface 22, a clamp-type flat end interface 23, a flange interface 24, and a tapered compression interface 25. These different types of interfaces are compatible with most models of water pump outlets and inlet pipes on the market, greatly improving the applicability of the connector.

[0021] The adapter interface group 2 adopts a modular structure, with each interface connected by a precise rotary locking mechanism, allowing for quick replacement of different types of interfaces as needed. The quick-connect internal thread interface 21 is suitable for connecting to the outlet of an externally threaded water pump; the quick-connect external thread interface 22 is suitable for connecting to internally threaded pipes; the clamp-type flat end interface 23 is suitable for connecting to flexible hoses; the flange interface 24 is suitable for connecting to standard flange interface equipment; and the tapered compression interface 25 is suitable for connecting to smooth, unthreaded pipes.

[0022] The sealing system 3 includes a double-layer sealing structure disposed within each standard interface. The double-layer sealing structure includes an inner deformable elastomer sealing ring 31 and an outer pressure-responsive liquid sealant 32.

[0023] The deformable elastomer sealing ring 31 is made of high-quality silicone rubber, with a temperature range of -40℃ to 200℃, and exhibits excellent elasticity and durability. The sealing ring 31 has a composite curved surface structure, which can adapt to connection surfaces of different shapes. It has multiple micro elastic protrusions 311 on the inner side, which can deform under pressure to increase the contact area and improve the sealing effect.

[0024] Pressure-responsive liquid sealant 32 is encapsulated in an annular cavity 33 inside the connector body 1, and communicates with the interface connection through a microchannel 34. When the interface is connected and subjected to pressure, the pressure is transmitted to the annular cavity 33 through the microchannel 34, causing the liquid sealant 32 to flow out and fill the tiny gaps at the connection, forming an auxiliary sealing layer. The liquid sealant 32 is made of water-resistant, oil-resistant, and corrosion-resistant silicone material, and can automatically flow back to the annular cavity 33 when the fluid pressure decreases, facilitating future use.

[0025] The adaptive locking mechanism 4 includes multiple elastic claws 41 distributed around the outer periphery of the connector body 1 and miniature guide grooves 42 that engage with the elastic claws 41.

[0026] The elastic claw 41 includes a main body 411 and a locking part 412. The main body 411 is hinged to the connector body 1 and can rotate around the hinge point. The locking part 412 has an arc-shaped structure, which can accommodate connection devices of different diameters. Its inner side is provided with a first anti-slip texture 4121 to increase friction and prevent loosening of the connection; its outer side is provided with an operating protrusion 4122 for easy operation with fingers. The elastic claw 41 is made of high-strength engineering plastic, which has good elasticity and durability.

[0027] The miniature guide groove 42 is spirally arranged on the moving trajectory of the elastic claw 41, guiding the elastic claw 41 to move and lock along a preset trajectory. The design of the guide groove 42 generates axial pressure on the claw during the locking process, ensuring a tighter connection. The inner surface of the guide groove 42 is plated with hard alloy to improve wear resistance.

[0028] In practical applications, this multi-purpose water pump connector allows for the selection of appropriate interfaces to connect the water pump outlet and inlet pipe as needed. Taking the connection of a standard water pump and hose as an example, a quick-connect internal thread interface 21 can be used to connect the water pump outlet, while a clamp-type flat-mouth interface 23 can be used to connect the hose. During connection, first align the corresponding interfaces of the connector with the connection points, then push the elastic claw 41 along the micro guide groove 42 to the locking position. Under fluid pressure, the double-layer sealing system automatically activates, ensuring a leak-free connection.

[0029] This utility model of a multi-purpose water pump coupling, through the innovative combination of multiple types of interfaces, a double-layer sealing system, and an adaptive locking mechanism, successfully solves the technical problems of traditional water pump couplings, such as narrow applicability, poor sealing performance, insufficient connection strength, and inconvenient operation. It has significant practical value and promising prospects for widespread application.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
