Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire-fighting equipment technology, and in particular relates to a quick-connect fire hose interface. Background Technology
[0002] As a key water delivery component in fire fighting operations, the reliability and efficiency of the connection between the fire hose and the interface directly affect the timeliness and effectiveness of fire fighting and rescue. Currently, the traditional connection method between the fire hose and the interface has been used for many years. The specific operation procedure is as follows: First, put the end of the fire hose on the outer wall of the hose interface. In order to avoid the metal edge of the interface from abrading the hose, a soft protective material such as rubber sheet or canvas should be placed at the contact point between the two. Then, wrap galvanized iron wire around the joint between the hose and the interface 3 to 5 times. Tighten and fix the two ends of the iron wire with a special tool, or use a hose clamp (i.e., metal pipe clamp) on the outside of the hose and fix it by tightening the bolts.
[0003] This traditional connection method has drawbacks: First, the operation process is cumbersome, requiring multiple steps such as padding and protecting materials, wrapping wire or installing hose clamps, and tightening. In an emergency fire, each connection usually takes more than a minute, seriously delaying the firefighting opportunity. Second, it requires high skill from the operators. The tightness of the wire needs to be precisely controlled. If it is too loose, it will easily lead to water leakage, and if it is too tight, it will tear the end of the hose. New firefighters need to undergo several weeks of specialized training to master it, which increases training costs.
[0004] To address these issues, we provide a quick-connect fire hose interface. Utility Model Content

By combining the connector, connecting hose, and connecting components, it solves the problem that the traditional fire hose connection method in the prior art cannot achieve quick connection with the hose interface in an emergency.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] The present invention is further configured such that an anti-slip disc is fixedly connected to the surface of the fixing ring, the surface of the anti-slip disc is provided with anti-slip texture, and the anti-slip disc and the fixing ring form an integral structure, which can increase the area and surface friction of the fixing ring, making it convenient for firefighters to operate and connect water hoses.
[0009] The present invention is further configured such that a limiting rod is fixedly connected to the top and bottom of one side of the pressure plate, and the limiting rod is connected through a limiting hole on the surface of the mounting shell. The limiting rod moves with the pressure plate in the limiting hole on the surface of the mounting shell, and the limiting action of the limiting rod can improve the movement stability of the pressure plate.
[0010] The present invention is further configured such that a sealing sleeve is fixedly connected to one side of the pressure plate, the surface of the sealing sleeve is movably connected to the inner cavity of the connector, the sealing sleeve moves with the pressure plate and moves in the inner cavity of the connector, the sealing sleeve will not move out of the inner cavity of the connector, and the sealing effect of the sealing sleeve can prevent water backflow from eroding the spring.
[0011] The present invention is further configured such that a limiting sleeve is fixedly connected to one side of the pressure plate, the surface of the limiting sleeve is in contact with the inner wall of the insertion tube, and as the insertion tube is inserted into the inner cavity of the mounting shell, the limiting sleeve on one side of the pressure plate is stuck in the inner wall of the insertion tube, thereby improving the connection sealing between the insertion tube and the pressure plate through the limiting sleeve.
[0012] The present invention is further configured such that a sealing ring is fixedly connected to the inner wall of the opening on one side of the mounting shell.

After the insertion tube is inserted into the inner cavity of the mounting shell, the sealing ring wraps around the surface of the insertion tube, thereby improving the sealing performance between the insertion tube and the mounting shell through the sealing effect of the sealing ring.
[0013] The present invention is further configured such that a compression ring is fixedly connected to the inner wall of the collar, and the inner wall of the compression ring is in close contact with the surface of the insertion tube. After the insertion tube passes through the inner cavity of the collar, the compression ring in the inner cavity of the collar tightly wraps around the surface of the insertion tube, thereby further improving the connection and sealing between the insertion tube and the mounting shell.

The connection can be completed quickly by simply inserting the tube into the opening on one side of the mounting shell, rotating the tube to insert the rod into the insertion hole on the surface of the mounting shell under the action of the spring, and rotating the buckle plate to complete the fixation. This can greatly shorten the connection time in emergency fire situations and save valuable time for fire fighting and rescue.
[0017] 2. This utility model reduces the skill requirements for operators and lowers training costs. In the traditional method, the tightening force of the wire needs to be precisely controlled, and new firefighters need several weeks of specialized training to master it. However, this quick connection method achieves convenient and standardized connection through the design of the mechanical structure. Operators can complete a reliable connection without complicated skills, avoiding problems such as water leakage or hose tearing caused by improper force control. Attached Figure Description

[0029] Specifically: After aligning the retaining plate 204 on the surface of the insertion tube 3 at one end of the connecting hose 5 with the opening on the surface of the mounting shell 201, insert the insertion tube 3 into the inner cavity of the mounting shell 201, and rotate the insertion tube 3 after squeezing the pressure plate 203 until the insertion rod 205 on one side of the retaining plate 204 on the surface of the insertion tube 3 is aligned with the insertion hole on the surface of the mounting shell 201. Release the insertion tube 3, and the insertion rod 205 on the surface of the retaining plate 204 will be inserted into the insertion hole under the action of multiple sets of springs 202, thereby quickly completing the connection between the connecting hose 5 and the connector 1.
[0030] Example 2
[0031] Please see Figure 1-6 Based on Embodiment 1, an anti-slip disc is fixedly connected to the surface of the fixing ring 4, and the surface of the anti-slip disc is provided with anti-slip texture. Limiting rods 6 are fixedly connected to the top and bottom of one side of the pressure plate 203. The limiting rods 6 are connected through the limiting holes on the surface of the mounting shell 201. A sealing sleeve is fixedly connected to one side of the pressure plate 203. The surface of the sealing sleeve is movably connected to the inner cavity of the connector 1. A limiting sleeve is fixedly connected to one side of the pressure plate 203. The surface of the limiting sleeve is in contact with the inner wall of the insertion tube 3. A sealing ring 7 is fixedly connected to the inner wall of the opening on one side of the mounting shell 201. The inner wall of the sealing ring 7 is in contact with the surface of the insertion tube 3. A compression ring is fixedly connected to the inner wall of the collar 206. The inner wall of the compression ring is in tight contact with the surface of the insertion tube 3. A reinforcing sleeve is fixedly connected to one side of the fixing ring 4. The inner wall of the reinforcing sleeve is fixedly connected to the surface of the connecting water hose 5.
[0032] Specifically: The anti-slip disc and the fixing ring 4 form an integral structure, which can increase the area and surface friction of the fixing ring 4, making it easier for firefighters to connect the water hose 5. The limiting rod 6 moves with the pressure plate 203 in the limiting hole on the surface of the mounting shell 201. The limiting action of the limiting rod 6 can improve the movement stability of the pressure plate 203. The sealing sleeve moves with the pressure plate 203 and moves in the inner cavity of the connector 1. The sealing sleeve will not move out of the inner cavity of the connector 1.

After the insertion tube 3 is inserted into the inner cavity of the mounting shell 201, the sealing ring 7 wraps around the surface of the insertion tube 3. The sealing effect of the sealing ring 7 improves the sealing of the connection between the insertion tube 3 and the mounting shell 201. After the insertion tube 3 passes through the inner cavity of the collar 206, the compression ring of the inner cavity of the collar 206 tightly wraps around the surface of the insertion tube 3, thereby further improving the sealing of the connection between the insertion tube 3 and the mounting shell 201. One side of the reinforcing sleeve is connected to the fixing ring 4, and its inner wall is connected to the connecting water hose 5. The reinforcing sleeve improves the connection strength between the connecting water hose 5 and the fixing ring 4.
[0033] The working principle of this utility model is as follows: Firefighters hold the connecting hose 5 and align the clamping plate 204 on the surface of the insertion tube 3 at one end of the connecting hose 5 with the opening on the surface of the mounting shell 201. Then, the insertion tube 3 is inserted into the inner cavity of the mounting shell 201, and the insertion tube 3 is rotated after squeezing the pressure plate 203 until the insertion rod 205 on one side of the clamping plate 204 on the surface of the insertion tube 3 is aligned with the insertion hole on the surface of the mounting shell 201. The insertion tube 3 is then released, and the insertion rod 205 on the surface of the clamping plate 204 is inserted into the insertion hole under the action of multiple sets of springs 202. Then, the buckle plate 207 is rotated so that the protrusions on one side of the two buckle plates 207 are inserted into the through hole on the surface of the positioning plate 208. The connection stability between the connector 1 and the connecting hose 5 is improved by the two sets of buckle plates 207 and the positioning plate 208, thereby quickly completing the connection between the connecting hose 5 and the connector 1.
