Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, in particular to a fire hose. Background Art

[0002] The water hose used for fire fighting or water delivery in industrial and agricultural production is usually composed of a woven layer and an inner lining layer. It is soft and can withstand high-pressure water flow. Fire joints are generally provided at both ends of the water hose, and the two water pipes can be connected together through the joints. Due to the urgency of the fire on the scene, the water hose needs to be laid quickly. When the fire hose is laid, it involves adjusting the position of the fire hose, so it needs to be dragged. The existing fire hose will be worn during the dragging process, and the longer laid fire hose is heavier and not easy to move.

[0003] A fire hose disclosed in the publication number CN201050647Y, although, the utility model discloses a fire hose, including a hose braided layer and an inner lining rubber layer, which has a PVC plastic coating layer outside the hose braided layer. The PVC plastic layer is coated on the outside of the hose braided layer and the hose braided layer is woven with high-strength polyester yarn or polypropylene yarn, which can greatly improve the pressure resistance of the hose, thereby extending the service life, and has the characteristics of low investment cost and significant quality improvement.

[0004] However, this fire hose has the following disadvantages:

[0005] (1) The fire hose rubs against the ground during the dragging process, and the longer the fire hose is, the greater the friction coefficient with the ground is. The fire hose is not convenient for reducing the friction with the ground to facilitate the dragging of the fire hose and avoid surface damage caused by long-term friction between the fire hose and the ground;

[0006] (2) It is not convenient to quickly reel in the fire hose by hand, and after reeling in, it needs to be pressed and fixed. Utility Model Content

[0018] (III) Beneficial effects

[0019] The utility model provides a fire hose, which has the following beneficial effects:

[0020] 1. The fire hose, through the comprehensive setting of anti-wear rings and auxiliary moving components, when laying the fire hose, several anti-wear rings are arranged on the hose, so that the hose and the ground form a space to avoid the hose directly rubbing against the ground. At the same time, the eight rotating wheels arranged on the anti-wear ring can roll with the hose and assist the hose to change position when the hose is moved, thereby extending the service life of the fire hose, making it convenient for firefighters to drag the fire hose and improving the convenience of using the fire hose.

[0021] 2. The fire hose, through the arrangement of the winding drum and the pressing component, flattens the hose and inserts it into the embedded groove, and rotates the hand-cranked mechanism so that the hose is wound along with the rotation of the winding drum. After the winding is completed, the handle is held and turned to drive the threaded column to rotate to a suitable position on the inner teeth of the thread, so that the pressing plate presses and fixes one side of the hose, thereby facilitating the firefighters to quickly hand-crank the fire hose and fix it for storage, thereby saving time for the firefighters' finishing work and improving the practicality of the fire hose.

[0030] The outer surface of the bearing 2 is connected to the middle part of the surface of the rotating disk 1, and the inner part of the bearing 2 is connected to the outer surface of the winding drum 3. The width of the winding drum 3 is smaller than the folding width of the water hose 5, and the water hose 5 is rolled up on the outside of the winding drum 3 to play a storage role.

[0031] The pressing assembly 7 includes a threaded column 701 threadedly connected to the inside of the threaded inner thread 6, and one end of the threaded column 701 is fixedly connected to a pressing plate 702, which can squeeze and fix the side of the water hose 5.

[0032] The handheld component 8 includes a handle 801 fixedly mounted on one side of the pressure plate 702 , and a sponge sheet 802 is fixedly attached to the surface of the handle 801 . The provision of the sponge sheet 802 allows the user to feel more comfortable when squeezing the handle 801 .

[0033] The hand-crank mechanism 9 includes a receiving tube 901 fixedly connected to one end of the bearing 2, and one end of the receiving tube 901 is fixedly connected to a hand-crank lever 902. The hand-crank lever 902 rotates to drive the receiving tube 901 and the winding drum 3 to rotate synchronously, so that the water hose 5 is quickly wound up.

[0034] The surface of the hand crank 902 is sleeved with an anti-skid cover 13, which is made of rubber. The provision of the anti-skid cover 13 can prevent firefighters from slipping due to excessive water stains.

[0035] The auxiliary moving component 12 includes a rotating roller 1201 rotatably connected to the inside of the rotating groove 11 , and a rotating wheel 1202 is fixedly connected to the middle of the surface of the rotating roller 1201 . The rotating roller 1201 drives the rotating wheel 1202 to rotate on the anti-wear ring 10 .

[0036] The anti-wear ring 10 is made of rubber, and eight rotating grooves 11 are distributed in a ring shape on the surface of the anti-wear ring 10. The rotating grooves 11 arranged in eight directions of the anti-wear ring 10 provide eight directions of rotating space for the auxiliary moving component, thereby preventing the water hose 5 from contacting the ground in all directions.

[0037] In the utility model, the working steps of the device are as follows:

[0038] Step 1: When laying the fire hose, the firefighter holds the handle 801 and rotates it clockwise, so that the threaded column 701 is disengaged from the inner thread 6, and then another person holds one end of the hose 5 to lay and stretch it, and the hose 5 is quickly extended outward on the reel 3 until the hose 5 is completely placed on the ground. At this time, the setting of several anti-wear rings 10 on the hose 5 creates space between the hose 5 and the ground, avoiding direct contact between the surface of the hose 5 and the ground. When dragging, the rotating wheel 1202 on the anti-wear ring 10 rolls, reducing the friction coefficient between the hose 5 and the ground;

[0039] The second step: when the firefighting is over, one end of the water hose 5 is flattened and inserted into the inside of the embedding groove 4, and then the hand crank 902 is rotated. The rotation of the hand crank 902 drives the winding drum 3 to rotate synchronously, so that the water hose 5 inserted into the embedding groove 4 is wound and rotated until the water hose 5 is completely wound onto the winding drum 3, and then the handle 801 is held, the threaded column 701 is aligned with the inner thread teeth 6, and rotated. Under the inward action of the threaded column 701, the pressure plate 702 moves to a suitable position and presses one side of the water hose 5, and the width of the water hose 5 is larger than the winding drum 3, so that the water hose 5 is squeezed and fixed by the pressure plate 702.
