Technical Field
[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting hose wearing joint. Background Art
[0002] Fire hoses are hoses used to transport fire-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and covered with linen woven fabric. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal connectors at both ends of the fire hose, which can be connected to another hose to extend the distance or connected to a nozzle to increase the liquid injection pressure. The huge pressure requires a pipe connector with a high-strength connection structure to connect, so as to ensure the stability of the connection.
[0003] Although the existing fire-fighting joints can meet the needs, the connection is not firm enough. Once the connecting head is rotated, it may fall off, which is not conducive to fire fighting.
[0004] In order to solve this problem, the utility model is produced. Utility Model Content

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is to provide a fire hose wearing joint, including a first joint and a second joint connected to the fire hose, the first joint is provided with a first channel for water flow to pass through, the second joint is provided with a second channel for water flow to pass through, the first joint is provided with a clamping channel, the second joint is provided with a clamping platform, the clamping platform is passed through the clamping channel, the clamping platform is provided with a fastening channel, the first joint is slidably passed through a fastening rod, one end of the fastening rod can slide into the fastening channel, the other end of the fastening rod passes through the first joint, and the first joint is provided with a pushing device for pushing the fastening rod to slide into the fastening channel.
[0007] A further improvement is that the pushing device includes a rotating ring, which is threadedly connected to the outer wall of the first joint, and the inner wall of the rotating ring is provided with a first inclined surface with a cross section gradually inclined from left to right. The end of the fastening rod located on the rotating ring is a spherical head, and the spherical head resists the first inclined surface. A releasing device for releasing the engagement of the fixing rod is also provided in the first joint.
[0008] A further improvement is that the release device includes a sliding plate, a first channel is opened in the first joint, the fastening rod is located in the first channel, the sliding plate is arranged on the fastening rod and located in the first channel, and a return member is provided in the first channel.
[0009] A further improvement is that the return member is a spring, one end of the spring is connected to the sliding plate, and the other end of the spring is connected to the inner wall of the first channel.
[0010] A further improvement is that: the other end of the fastening rod located at the rotating ring is provided with a second inclined surface which is gradually inclined from left to right, and the fastening channel is arranged to match the fastening rod.
[0011] The advantages and beneficial effects of the utility model are:
[0012] The structure is simple, the connection is convenient, and the fastening performance is good. By rotating the rotating ring, the fastening rod can be driven to engage with the fastening channel, and the further the rotating ring is turned downward, the better the fastening effect. The assembly is convenient, and the rotation of the second joint can be limited so that the joint will not rotate and will not be loosened, thereby improving the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the cutaway structure of a fire hose wearing joint according to an embodiment of the utility model. DETAILED DESCRIPTION
[0014] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0015] like Figure 1 As shown, a fire hose wearing joint comprises a first joint 1 and a second joint 2 connected to the fire hose, the first joint 1 is provided with a first channel 3 for water flow to pass through, the second joint 2 is provided with a second channel 4 for water flow to pass through, the first joint 1 is provided with a clamping channel, the second joint 2 is provided with a clamping platform 5, the clamping platform 5 is penetrated in the clamping channel, a fastening channel is provided on the clamping platform 5, a fastening rod 6 is slidably penetrated by the first joint 1, one end of the fastening rod 6 can slide into the fastening channel, and the other end of the fastening rod 6 passes through the first joint 1, and the first joint 1 is provided with a pushing device for pushing the fastening rod 6 to slide into the fastening channel.
[0016] Specifically, the pushing device includes a rotating ring 7 and a sliding plate 10. The rotating ring 7 is threadedly connected and sleeved on the outer wall of the first joint 1. The inner wall of the rotating ring 7 is provided with a first inclined surface 8 whose cross section gradually inclines from left to right. The end of the fastening rod 6 located on the rotating ring 7 is a spherical head, and the spherical head resists the first inclined surface 8. A sliding channel 9 is provided in the first joint 1. The fastening rod 6 is located in the sliding channel 9. The sliding plate 10 is arranged on the fastening rod 6 and located in the sliding channel 9. A spring 11 is provided in the sliding channel 9. One end of the spring 11 is connected to the sliding plate 10, and the other end of the spring 11 is connected to the inner wall of the sliding channel 9.
[0017] In order to enable the fastener to penetrate into the fastening channel and the first joint 1 and the second joint 2 to be more tightened, the fastening rod 6 is located at the other end of the rotating ring 7 and is provided with a second inclined surface 12 which is gradually inclined from left to right, and the fastening channel is matched with the fastening rod 6.
[0018] Working principle:
[0019] During use, when the fire hose is to be connected, the engaging platform 5 of the second joint 2 is inserted into the engaging channel, and then the rotating ring 7 is turned downward, the rotating ring 7 moves downward, the first inclined surface 8 resists the fastening rod 6, and pushes the fastening rod 6 to slide inward, and pushes the fastening rod 6 to slide into the fastening channel to engage, and the spring 11 is stretched. When the water hose is to be disassembled, the rotating ring 7 is reversed, the rotating ring 7 moves upward, the spring 11 is reset, and the fastening rod 6 is driven back to its original position, so that the fastening rod 6 slides out of the fastening channel, so that the fastening rod 6 is released from the engagement with the fastening channel, thereby releasing the second connector, and then the second connecting connector is taken out, and the water hose can be disassembled. It is simple and convenient, and the connection tightness is good, and the first connector 1 and the second connector 2 are not easy to be separated.
