Description

Technical Field

[0001] This utility model relates to the field of fire pump technology, specifically a socket-type fire pump coupling. Background Technology

[0002] In fire protection systems, fire pump connections are key devices specifically designed for fire protection systems. They connect to fire trucks via a socket-type quick-connect interface. The "socket-type" design emphasizes speed, reliability, and efficiency, making it an indispensable component in modern firefighting equipment for ensuring efficient firefighting and rescue operations. They typically feature prominent and standard signage and must not be obstructed or enclosed; the area must be kept clear and easily accessible for operation.

[0003] Existing technology disclosure number CN223331357U discloses a fire pump coupling, belonging to the field of fire pump technology. It includes a pump body, a base mounted on the bottom of the pump body, multiple sets of mounting pins mounted on the base, pipes mounted at both ends of the pump body, the pipes communicating with the pump body, an installation assembly installed inside the pipe, a coupling assembly installed within the installation assembly, a connecting pipe fixedly connected to the end of the pipe, a corresponding fixed pipe installed on one side of the connecting pipe, and a snap-fit ​​assembly installed on the fixed pipe. This utility model installs a coupling assembly inside the pipe. After the fire pipe and the connecting pipe head are connected, they are connected by entering the pipe and the coupling assembly, thus achieving a tight connection between the fire pipe and the fire pump. The snap-fit ​​assembly installed on the fixed pipe and the installation assembly installed inside the pipe, through the cooperation of the two components, prevents misalignment during pipe connection and also triggers the expansion tube on the coupling assembly to pop out, making the internal connection even tighter.

[0004] While the above methods offer certain advantages in preventing disconnections, they also have some drawbacks.

[0005] 1. Fire hydrants typically use high-pressure water supply, which lacks leak-proof design, making it easy for water to leak from the connections.

[0006] 2. Furthermore, there is no quick connection method for general fire pump connections, which can easily lead to a lot of wasted time. Utility Model Content

[0007] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a socket-type fire pump coupling.

[0011] Preferably, the inner side of the ring plate is provided with a serrated groove, and the serrated groove and the serrated plate mesh with each other. The connecting plate is slidably connected to the left side of the inner side of the frame plate by inserting a limiting post. The locking block is slidably connected to the right side of the inner side of the frame plate by inserting a limiting post. The side of the locking block near the connecting head tube and the inner wall of the groove of the locking hole are provided with chamfers or rounded corners.

[0028] Example 1:

[0029] Please see Figures 1-6This utility model discloses a socket-type fire pump coupling, comprising a fire pump 1, a coupling 2 fixedly connected to the outlet of the fire pump 1, a connecting head pipe 3 inserted and slidably connected to the inner side of the coupling 2, multiple slots 4 formed on the outer side of the connecting head pipe 3, a groove 5 formed on the inner side wall of the coupling 2, multiple locking blocks 6 inserted and slidably connected to the inner side wall of the coupling 2, a frame plate 7 rotatably connected to the inside of the coupling 2, a cylinder 8 slidably connected to the inner side of the groove 5, multiple connecting rods 9 inserted and slidably connected to the right end face of the cylinder 8, and a rubber sealing ring plate 10 fixedly connected to the right side face of the connecting rods 9. A spring 11 is fixedly connected to the left end face of the connecting rod 9 and the inner side wall of the cylinder 8. A helical tooth plate 12 is fixedly connected to the outer side of the cylinder 8. Multiple connecting posts 13 are fixedly connected to the left side of the cylinder 8, and the connecting posts 13 are slidably connected to each other by inserting into the inner left end face of the groove 5. Two reserved openings 14 are opened on the left side of the connecting post 13. A limit rod 15 is inserted into the reserved opening 14 and slidably connected to it. The left end of the limit rod 15 is fixedly connected to the connector 2. A sliding groove 16 is opened on the inner side wall of the reserved opening 14, and the limit rod 15 and the sliding groove 16 are slidably connected to each other. A reset spring 17 is fixedly connected to the left end face of the connecting post 13.

[0030] The connector 2 is internally connected to a ring plate 18, which has multiple arc grooves 19. Limiting posts 20 are slidably connected to the inner side of each arc groove 19. Multiple connecting plates 21 are slidably connected to the outer side of the ring plate 18, and the connecting plates 21 are fixedly connected to the limiting posts 20. A helical toothed groove 22 is provided on the inner side of the ring plate 18, and the helical toothed groove 22 meshes with the helical toothed plate 12. The connecting plates 21 are slidably connected to the inner left side of the frame plate 7 via the insertion of the limiting posts. The locking blocks 6 are slidably connected to the inner right side of the frame plate 7 via the insertion of the limiting posts. The locking blocks 6 are provided with locking posts on the side near the connecting head tube 3 and on the inner wall of the groove of the locking slot 4. The rubber sealing ring plate 10 has chamfers or rounded corners and is made of fluororubber or nitrile rubber. There are three or four locking blocks 6, which are evenly distributed along the inner circumference of the connector 2. The inclination angle of the toothed bevel on the inclined tooth plate 12 and the toothed bevel on the inclined tooth groove 22 is 45°. At least one of the surfaces of the connecting head tube 3 in contact with the inner wall of the connector 2 and the surfaces of the locking blocks 6 in contact with the frame plate 7 is fitted with a friction-reducing bushing. The body of the connector 2 is made of aluminum alloy and the connecting head tube 3 is made of stainless steel. Another auxiliary sealing ring is also fixedly embedded on the right side of the rubber sealing ring plate 10, and the cross section of the auxiliary sealing ring is O-shaped or X-shaped.

[0031] The working principle of a socket-type fire pump connection based on Embodiment 1 is as follows:

[0032] First, when using, forcefully insert the connector tube 3 that needs to be connected into the inside of the connector 2, so that the connector tube 3 contacts the rubber sealing ring plate 10 and pushes the rubber sealing ring plate 10 to move, thereby driving the connecting rod 9 to apply pressure to the spring 11. At the same time, the spring 11 rebounds and pushes the cylinder 8 to slide inside the groove 5, simultaneously driving the helical tooth plate 12 and the connecting column 13 to move.

[0033] Second, when the helical tooth plate 12 moves, it drives the ring plate 18 to rotate through the helical tooth groove 22, drives the limiting post 20 to rotate through the arc groove 19, and pulls the connecting plate 21 to move. This causes one end of the frame plate 7 to rotate through the rotating connection point inside the connector 2 as a fulcrum, and in turn drives the locking block 6 to move and lock into the inside of the locking slot 4.

[0034] Third, when the connecting column 13 moves, the limiting rod 15 is stationary. The return spring 17 is pressed, and the limiting rod 15 slides inside the slide groove 16. The slide groove 16 limits the movement. The return spring 17 rebounds and pushes the connecting column 13 to move, shortening the movement distance. This prevents the locking block 6 from moving into the slot 4 and simultaneously disengaging. After completion, the force applied to the connector 2 is released. At this time, the spring 11 rebounds and pushes the connecting rod 9 to drive the rubber sealing ring plate 10 to resist the connecting head tube 3 in the opposite direction. This allows for quick installation and greatly prevents water leakage. Conversely, when disassembly is required, simply apply a pushing force to the connecting head tube 3 again, which will drive the locking block 6 to move away from the slot 4 and quickly remove the connecting head tube 3.

[0035] This utility model provides an improved socket-type fire pump connector. In use, the connector pipe 3 is forcefully inserted into the inside of the connector 2, and the cylinder 8 slides inside the groove 5. Simultaneously, the helical tooth plate 12 and the connecting column 13 move. Through the limiting rod 15 and the sliding groove 16, the return spring 17 pushes the connecting column 13 to move while shortening the moving distance. At the same time, the locking block 6 moves and locks into the inside of the locking slot 4, which can also achieve quick installation. Conversely, the connector pipe 3 can be disassembled by applying a pushing force again. At the same time, when the spring 11 pushes the connecting rod 9 to drive the rubber sealing ring plate 10 to resist the connector pipe 3 in the opposite direction, it can also greatly prevent water leakage.

[0036] The above describes the basic principles, main features, and advantages of this utility model. All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings.
