Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a quick-installation fire water pipe connector. Background Technology

[0002] Firefighting equipment, such as conventional fire extinguishers and fire hydrants, is provided in all buildings. Fire hydrants are equipped with quick-connect fittings with flexible water pipes and water nozzles. However, commonly used fire hose fittings are time-consuming to install and can easily slip on the hands during use.

[0003] For example, CN220249258U discloses a quick-installation fire hose connector, which includes a main body device. The main body device includes a motion unit, an auxiliary unit, and a usage unit. The motion unit includes a nozzle, a fixed ring, a movable fixed ring, and a ring threaded sleeve. The auxiliary unit includes an auxiliary connecting pipe, a protective shell, a rectangular locking block, and a base. The usage unit includes a water supply pipe and a fixing screw. The auxiliary connecting pipe is located on top of the base, the nozzle is located on top of the protective shell, and the fixed ring is located at the bottom of the rectangular locking block.

[0004] As can be seen from the above-disclosed scheme, when using this connector, the nozzle is first rotated and fixed to the inner wall of the auxiliary connecting pipe. Then, the inner wall of the auxiliary connecting pipe and the movable fixing ring is fixed by the rectangular clamp. Next, the circular threaded sleeve and the fixed ring are connected by rotating the circular threaded sleeve. Then, the movable fixing ring is fixed to the top of the circular threaded sleeve. Finally, the movable fixing ring and the fixed ring are fixed together by the fixing screw. The whole installation process is quite cumbersome and complicated, which greatly increases the installation time and reduces the assembly efficiency. In addition, the surface of the connector is smooth, and the water pressure is large when the user sprays water to extinguish the fire, which makes it easy for the hand to slip off the auxiliary connecting pipe.

The connector has a connecting interface and a water inlet. A sealing gasket is fitted into the inner wall of the slot. The surface of the sealing gasket contacts and presses against one end of the connecting seat. This quick-installation fire hose connector, through the set seat, connecting seat, and locking block, can quickly fix the sprinkler head connecting pipe without the need for wrenches or other tools, greatly improving assembly efficiency. Furthermore, the set first and second anti-slip rods not only make it easy for the user to grip and rotate the sprinkler head connecting pipe during installation, but also allow the user to hold the sprinkler head connecting pipe firmly during fire spraying to prevent slippage and ensure the direction of fire spraying.

[0008] Furthermore, both the first and second anti-slip rods are arc-shaped, both have circular cross-sections, and both have anti-slip textures on their surfaces, making it easier for users to grip the fire hose nozzle.

[0009] Furthermore, the inner wall of the slot is provided with a positioning groove, and the bottom of the sealing gasket is provided with a retaining edge. Both the slot and the sealing gasket have an L-shaped cross-section, which facilitates the installation and removal of the sealing gasket.

[0010] Furthermore, the surface of the card block is provided with a countersunk hole, the inner wall of the countersunk hole is movably fitted with a screw, and the side of the connecting seat is provided with a threaded groove, so that the card block has the function of disassembly and assembly.

[0011] Furthermore, one end of the card block is provided with an abutment surface. Both the card block and the card seat are made of metal, and the material hardness of the card block is less than that of the card seat, which greatly reduces the wear of the card seat.

[0012] Furthermore, one end of the connecting seat is provided with a boss, which is circular in shape. The boss can ensure the compressive strength between the connecting seat and the sealing gasket, thereby ensuring its sealing performance.

[0013] Furthermore, the contact surface of the contact surface contacts and presses against the inner wall of the slot, allowing the card block to restrict the engagement position of the card seat and the connecting seat.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can quickly fix the nozzle connecting pipe by setting the card seat, connecting seat and card block, without the need to use wrenches or other tools for auxiliary fixing, which greatly improves the assembly efficiency.

[0016] (2) The first and second anti-slip rods in this solution not only make it easy for users to grip and rotate the nozzle connection pipe during installation, but also allow users to grip the nozzle connection pipe tightly during fire spraying to prevent it from slipping and ensure the direction of fire spraying.
