Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a rotatable indoor fire hydrant casting. Background Art

[0002] Indoor fire hydrants are used to supply water to the fire scene through indoor pipe networks. They have valve interfaces and are fixed indoor fire-fighting facilities in factories, warehouses, high-rise buildings, public buildings and ships. They are usually installed in fire hydrant boxes and are used in conjunction with equipment such as fire hoses and water guns.

[0003] Existing indoor fire hydrants are made of fire hydrant castings. After the fire hydrant is connected to the water hose, since the water hose interface is in a fixed direction, when the water hose is stretched in a direction inconsistent with the interface direction during fire fighting, it is easy to cause bending at the water hose port, which blocks the water flow in the water hose and causes poor water supply.

[0004] To solve this problem, the present invention is produced. Utility Model Content

[0005] Therefore, in view of the above-mentioned problems, the utility model proposes a rotatable indoor fire hydrant casting which has a simple structure and can rotate at an angle.

[0006] In order to solve the above technical problems, the solution adopted by the utility model is: a rotatable indoor fire hydrant casting, including a fire hydrant body, a water inlet pipe arranged on the fire hydrant body, and a fixed pipe connected to the water supply pipe, the water inlet pipe is rotatably mounted on the fixed pipe through a rotating device, a plurality of locking channels are opened on the fixed pipe around the array, a locking rod is slidably penetrated on the water inlet pipe, one end of the locking rod is located in the locking channel, and the other end of the locking rod passes through the water inlet pipe, and a pushing device for pushing against the locking rod is provided in the water inlet pipe.

[0007] A further improvement is that the abutting device comprises an abutting plate, the water inlet pipe is provided with a sliding channel, the abutting plate is fixed on the clamping rod, and an abutting piece is provided in the sliding channel.

[0008] A further improvement is that the push-up member is a spring, the spring is sleeved on the locking rod, one end of the spring resists the push-up plate, and the other end of the spring resists the inner wall of the sliding channel.

[0009] A further improvement is that the rotating device is a sealed bearing.

[0010] A further improvement is that a pull plate is provided on the engaging rod.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The structure is simple, and the angle can be rotated to facilitate fire extinguishing. When in use, the fire hydrant can be rotated, so that after the fire hose is connected, it can be stretched in the predetermined fire extinguishing direction, which can avoid the bending of the fire hose and is conducive to water discharge and fire extinguishing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The utility model is a schematic diagram of a rotatable indoor fire hydrant casting structure.

[0014] Figure 2 It is a schematic diagram of the enlarged structure of A in the embodiment of the present utility model.

[0015] Figure 3 It is a schematic diagram of a fixed pipe structure according to an embodiment of the utility model. DETAILED DESCRIPTION

[0016] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to Figure 1-Figure 3 The embodiment of the utility model discloses: a rotatable indoor fire hydrant casting, comprising a fire hydrant body 1, a water inlet pipe 3 arranged on the fire hydrant body 1, and a fixed pipe 2 connected to a water supply pipe, wherein the water inlet pipe 3 is rotatably sleeved on the fixed pipe 2 through a sealing bearing, a plurality of engaging channels 4 are opened on the fixed pipe 2 around an array, an engaging rod 5 is slidably penetrated on the water inlet pipe 3, one end of the engaging rod 5 is located in the engaging channel 4, and the other end of the engaging rod 5 passes through the water inlet pipe 3, and a resisting device for resisting the engaging rod 5 is provided in the water inlet pipe 3.

[0018] Specifically, the resisting device includes a resisting plate 6, the water inlet pipe 3 is provided with a sliding channel 7, the resisting plate 6 is fixed on the locking rod 5, a spring 8 is provided in the sliding channel 7, the spring 8 is sleeved on the locking rod 5, one end of the spring 8 resists the resisting plate 6, and the other end of the spring 8 resists the inner wall of the sliding channel 7.

[0019] In order to facilitate pulling the locking rod 5 , a pulling plate 9 is provided on the locking rod 5 .

[0020] Working principle:

[0021] When in use, after the fire hydrant is connected to the fire hose, the engaging rod 5 is pulled, the engaging rod 5 is disengaged from the engaging channel 4, and the spring 8 is compressed. Then the fire hydrant is rotated to adjust the fire hydrant to a predetermined fire extinguishing direction, and then the engaging rod 5 is released, the spring 8 is reset, and the engaging rod 5 is pushed to slide into the engaging channel 4 to engage, thereby limiting the rotation of the fire hydrant, so that it can stably discharge water for fire extinguishing. When the fire hydrant is rotated to the fire hose extinguishing direction, the fire hose can be prevented from bending, which is conducive to discharge of water for fire extinguishing.

[0022] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
