Description

Technical Field

[0001] This utility model belongs to the field of fire hose coupling technology, and in particular relates to a pressurized conversion hose interface. Background Technology

[0002] In fire protection, water conservancy projects, and industrial water supply, the rapid connection and reliable sealing of hose couplings are crucial for ensuring efficient and safe operations. Traditional hose couplings, when connected under pressure, suffer from problems such as difficulty in alignment, incomplete sealing, or even failure to connect due to water pressure impacts. This easily leads to water waste and pressure loss, severely impacting emergency rescue or project progress. Furthermore, traditional hose couplings rely heavily on manual operation for water discharge control. In emergencies, manual shut-off is slow, and the timing of water discharge is difficult to control precisely, potentially missing critical operating time. Moreover, the high intensity of manual operation makes them unsuitable for prolonged work. With the industry's increasing demands for operational efficiency and safety, there is an urgent need for a new type of hose coupling that overcomes these shortcomings. Utility Model Content

With the ball valve structure, it can also realize emergency water stoppage, which can significantly shorten the hose connection time, enable fire water to be delivered to the fire scene in a timely manner, effectively improve fire fighting efficiency, and reduce disaster losses.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a female head and a male head; the male head engages with the inner side of the front port of the female head via a snap-fit ​​groove at the port, thereby achieving the insertion and fixing of the female head and the male head; wherein, the female head consists of a middle cavity and a tail valve pipe; the upper end of the middle cavity is provided with an L-shaped track groove, in which a water valve hinge switch component one is movably engaged in the horizontal track of the L-shaped track groove, and in which a water valve hinge switch component two is movably engaged in the longitudinal track of the L-shaped track groove; a rotating gear engages with the upper rack at the front end of the water valve hinge switch component one and the upper outer rack at the upper end of the water valve hinge switch component two, thereby achieving the linkage between the water valve hinge switch component one and the water valve hinge switch component two; the lower end of the middle cavity is provided with a baffle groove, and the left side of the baffle groove is connected to a vertically distributed water valve baffle via a spring shaft, wherein the inner side of the upper edge of the water valve baffle engages with the water valve hinge switch component two to achieve baffle limiting.

[0008] Preferably, the outer side of the male connector is fitted with an unlocking ring, which presses the retaining spring inward to disengage it from the retaining groove, thereby separating the female and male connectors.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows: 1. High-efficiency pressurized connection: The pressurized conversion hose interface can realize pressurized connection and conversion, which completely solves the problem that traditional interfaces need to be depressurized before connection.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0021] See Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes a female connector 1 and a male connector 2; the male connector 2 is engaged with the inner retaining spring 5 of the front port of the female connector 1 through the snap-fit ​​groove 6 at the port, thereby realizing the insertion and fixing of the female connector 1 and the male connector 2; wherein, the female connector 1 is composed of an intermediate cavity 11 and a tail valve pipe 12; the upper end of the intermediate cavity 11 is provided with an L-shaped track groove 13, and a water valve hinge switch component 14 is movably engaged in the transverse track of the L-shaped track groove 13, and a water valve hinge switch component 14 is movably engaged in the longitudinal track of the L-shaped track groove 13. A water valve hinge switch component 2 16 is connected. The rotating gear 15 is engaged with the upper rack at the front end of the water valve hinge switch component 14 and the upper outer rack at the upper end of the water valve hinge switch component 2 16, thereby realizing the linkage between the water valve hinge switch component 14 and the water valve hinge switch component 2 16. A baffle groove 17 is provided at the lower end of the intermediate cavity 11. The left side of the baffle groove 17 is connected to a vertically distributed water valve baffle 18 through a spring shaft. The upper edge of the water valve baffle 18 is engaged with the water valve hinge switch component 2 16 to achieve baffle limiting.

[0022] The tail valve pipe 12 contains a ball valve 19, which is connected to an external manual control handle 3 at both ends. The ball valve 19 can be rotated by turning the manual control handle 3 to quickly stop the water flow, thus meeting emergency water shut-off requirements.

[0023] Furthermore, the water valve hinge switch component 14 and the water valve hinge switch component 2 are respectively connected to the reserved grooves in the middle, with slide rail wheels 4 connected to them. The slide rail wheels 4 are engaged with the concave tracks on the left and right side walls of the L-shaped track groove 13. The slide rail wheels 4 can ensure the sliding stability of the water valve hinge switch component 14 and the water valve hinge switch component 2, and avoid wear that could lead to gaps in the connection.

[0024] In addition, an unlocking ring 7 is sleeved on the outer side of the male head 2. The unlocking ring 7 presses the retaining spring 5 inward to disengage it from the retaining groove 6, thereby separating the female head 1 and the male head 2.

[0025] The working principle of this specific embodiment is as follows: In the static state, the water valve baffle 18 remains upright. At this time, the lower end of the water valve hinge switch component 16 is locked and limited by the upper edge of the water valve baffle 18, which can lock the female head 1. When the male head 2 is inserted into the female head 1, the male head 2 pushes the water valve hinge switch component 14 inward during the insertion process, and lifts the water valve hinge switch component 16 upward under the transmission action of the rotating gear 15. When the water valve hinge switch component 16 separates from the water valve baffle 18, the water valve baffle 18 automatically flips downward under the action of water pressure to achieve the purpose of pressurized connection. At this time, the water valve baffle 18 is hidden inside the baffle groove 17. When emergency water stop is required, the manual control handle 3 is manually turned to drive the ball valve 19 to rotate and cut off the water flow. When connecting and unlocking, the unlocking ring 7 is pressed inward, the unlocking ring 7 squeezes the retaining spring 5 and pushes it outward, so that the retaining spring 5 is separated from the retaining groove 6 to complete the separation.
