Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a fire hose with a multi-functional hose-tying mechanism. Background Technology

[0002] Fire hoses typically have a double-layer structure. The outer layer is a woven layer made of materials such as polyester filament or linen filament, while the inner layer is a lining made of materials such as PVC, rubber, or polyurethane. The inner and outer layers are bonded together by hot pressing with epoxy resin. In field use, both ends of the fire hose are secured to the hose coupling with steel wire or clamps.

[0003] For example, Chinese patent CN 216319684 U, entitled "A Fire Hose Binding Device," includes a circular box. A fixing pipe is fixedly installed on the right inner wall of the circular box. Two annular grooves are opened on the inner side wall of the circular box, and wire boxes are movably connected in both annular grooves. Outlet pipes are fixedly connected to the side of each wire box near the fixing pipe. A ring of racks is fixedly installed on the outer side wall of each wire box. The upper part of the circular box is flat, and an mounting plate is fixedly installed on the rear side of the circular box. The fire hose and connector to be bound are connected to the fixing pipe. Then, iron wires are pulled out from the two outlet pipes, and the two iron wires are wrapped around the fire hose and fixedly connected to the two fixing strips respectively. Turning on the rotary motor drives the two gears to rotate, which in turn drives the two wire boxes to rotate through the two racks. This causes the outlet pipes to rotate around the fire hose to bind the fire hose, thus binding two strands of iron wire to the fire hose at the same time, thereby improving work efficiency.

[0004] While the fire hose tying device in the aforementioned patent is practical and convenient, it also has shortcomings. The patent uses a motor to drive the wire to tie the hose. If the motor malfunctions, the hose cannot be tied, and timely rescue cannot be carried out. Furthermore, manual tying is time-consuming, labor-intensive, inefficient, and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a fire hose with a multi-functional hose tying mechanism to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The fire hose with a multi-functional hose tying mechanism includes a connector and a hose connecting pipe disposed on one side of the connector. Two pressure plates are symmetrically and rotatably connected to the hose connecting pipe. A clamping plate is horizontally and slidably connected inside each of the two pressure plates. A screw is rotatably connected inside each of the two pressure plates, and a slider is screwed onto each of the two screws. The sides of the two sliders that are close to each other are fixedly connected to the peripheral side surfaces of the two clamping plates one-to-one. Each of the two pressure plates is provided with a limiting component for restricting the circumferential rotation of the slider. The peripheral side surfaces of the two clamping plates slide against the inner wall of the hose connecting pipe.

[0007] Furthermore, a sealing strip is provided on the peripheral side of both of the aforementioned abutment plates.

[0008] Furthermore, both of the aforementioned clamping plates are semi-circular.

[0009] Furthermore, a disc is coaxially provided at the end of both screws near the connector.

[0010] Furthermore, both of the limiting components include guide rods, both of the pressure plates have a sliding groove, the two guide rods are respectively disposed in the two sliding grooves, and the two sliders are slidably sleeved with the two guide rods in a one-to-one correspondence.

[0011] Furthermore, the end of the hose connecting pipe away from the connector is rounded, and the end of the connector near the hose connecting pipe is also rounded.

[0012] Compared with the prior art, the beneficial effects provided by this utility model are as follows: The fire hose with a multi-functional hose clamping mechanism is first fitted onto the hose connecting pipe. By rotating the two pressure plates, the inner walls of the two pressure plates fit against the circumferential side of the hose connecting pipe, clamping the hose. At the same time, the screw is rotated, and the screw drive drives the clamping plate to move towards the connector through the screw drive. The two clamping plates squeeze the hose, so that a part of the hose is located between the clamping plate and the hose connecting pipe. The hose is clamped by the cooperation between the two clamping plates and the inner wall of the hose connecting pipe, which can quickly fix the hose, deal with emergencies, and the hose fixation stability is very high, which can prevent the hose from falling off the hose connecting pipe.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-5 The present invention provides a technical solution for a fire hose with a multi-functional hose tying mechanism, comprising a connector 1 and a hose connecting pipe 2 disposed on one side of the connector 1. Two pressure plates 3 are symmetrically rotatably connected to the hose connecting pipe 2. A clamping plate 11 is horizontally slidably connected inside each of the two pressure plates 3. A screw 6 is rotatably connected inside each of the two pressure plates 3, and a slider 9 is screwed onto each of the two screws 6. The sides of the two sliders 9 that are close to each other are fixedly connected to the peripheral surfaces of the two clamping plates 11. Each of the two pressure plates 3 is provided with a limiting component for restricting the circumferential rotation of the slider 9. The peripheral surfaces of the two clamping plates 11 slide against the inner wall of the hose connecting pipe 2. Specifically, two hinge shafts 5 are symmetrically provided on the connector 1. A hinge block 4 is rotatably sleeved on each hinge shaft 5. One side of each hinge block 4 is fixedly connected to one end of each pressure plate 3. First, the water hose is sleeved on the water hose connecting pipe 2. By rotating the two pressure plates 3, the inner walls of the two pressure plates 3 fit against the circumference of the water hose connecting pipe 2, clamping the water hose. Then, by rotating the two screws 6, the screw drive drives the clamping plate 11 to move towards the connecting head 1. The two clamping plates 11 squeeze the water hose, so that a part of the water hose is located between the clamping plate 11 and the water hose connecting pipe 2. The water hose is clamped by the cooperation between the two clamping plates 11 and the inner wall of the water hose connecting pipe 2, which can quickly fix the water hose, deal with emergencies, and the water hose fixation stability is very high, which can prevent the water hose from falling off the water hose connecting pipe 2.

[0022] As a preferred technical solution, a sealing strip 12 is provided on the periphery of both clamping plates 11. Specifically, the sealing strip 12 is semi-circular, which improves the sealing performance between the inner wall of the hose connecting pipe 2 and the hose.

[0023] As a preferred technical solution, both clamping plates 11 are semi-circular. Specifically, the two clamping plates 11 are wrapped together to form a circle. In order to ensure that the peripheral surfaces of the two clamping plates 11 can be completely fitted with the inner wall of the water hose connecting pipe 2, thereby improving the sealing performance and preventing water leakage, preferably, the two pressure plates 3 are also semi-circular. The two pressure plates 3 are wrapped together to form a circle. In order to ensure that the inner walls of the two pressure plates 3 can be completely fitted with the peripheral surfaces of the water hose connecting pipe 2, thereby making the clamping more stable and improving the sealing performance to prevent water leakage.

[0024] As a preferred technical solution, a disc 7 is coaxially provided at one end of each screw 6 near the connector 1. Specifically, the longitudinal cross-sectional area of ​​the disc 7 is larger than that of the screw 6. The disc 7 is rotatably connected to the corresponding pressure plate 3, which can limit the movement of the screw 6 in the length direction, so that the screw 6 can only rotate within the groove 8.

[0025] As a preferred technical solution, both limiting components include guide rods 10, and both pressure plates 3 have a groove 8. The two guide rods 10 are respectively set in the two grooves 8. The two sliders 9 are slidably sleeved with the two guide rods 10 in a one-to-one correspondence. Specifically, the guide rods 10 restrict the circumferential rotation of the sliders 9, so that the sliders 9 can only move in a straight line along the length direction of the guide rods 10.

[0026] As a preferred technical solution, the end of the hose connecting pipe 2 away from the connector 1 is rounded, and the end of the connector 1 near the hose connecting pipe 2 is rounded. Specifically, when the two pressure plates 3 rotate, the rounded corners allow the clamping plate 11 to more smoothly "bypass" the end face of the hose connecting pipe 2, greatly reducing the possibility of jamming, scraping or hard collision, and avoiding collision and motion interference.

[0027] Working principle: The fire hose with multi-functional hose tying mechanism is first looped onto the hose connecting pipe 2. By rotating the two pressure plates 3, the inner walls of the two pressure plates 3 fit against the sides of the hose connecting pipe 2, clamping the hose. At the same time, the screw 6 is rotated, and the screw drive drives the clamping plate 11 to move towards the connector 1. The two clamping plates 11 squeeze the hose, so that a part of the hose is located between the clamping plate 11 and the hose connecting pipe 2. The hose is clamped by the cooperation between the two clamping plates 11 and the inner wall of the hose connecting pipe 2, which can quickly fix the hose, deal with emergencies, and the hose fixation stability is very high, which can prevent the hose from falling off the hose connecting pipe 2.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
