Description

Technical Field

[0001] The utility model relates to a water hose wrapping cloth for blocking water leakage points of a fire hose. Background Art

[0002] Fire hoses may be damaged due to friction during laying or bending after filling with water, resulting in leakage of high-pressure water and reduced water pressure. When a leak is found during use, due to the urgency of fire rescue, it is necessary to use hose wrapping cloth to quickly seal the leak on site to prevent the leak from further expanding.

[0003] In the past, the hose wrap was composed of a polyester strap and a fixing fixture such as a metal clamp. When in use, the strap needs to be clamped with the fixing fixture. However, the previous method of fixing the hose wrap is not convenient enough. The operator needs to perform multiple steps and cannot complete the fixing of the hose wrap in a one-time operation. In addition, it is difficult for the clamp to clamp the wrap, which makes it easy for the wrap to slide loose, causing water to leak from the gap between the wrap and the hose, and it is impossible to effectively pressurize and seal the leaking part of the hose. In addition, due to the shape and weight of the fixing fixture, the previous hose wrap occupies a large storage space and is not portable enough. Utility Model Content

[0004] The utility model is completed in order to solve the above-mentioned problem, and its purpose is to provide a hose wrapping cloth which has a light structure and can quickly and effectively seal the water leakage point of the fire hose with simple operation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A hose wrapping cloth, which is used to seal the water leakage point of the hose, is characterized in that the hose wrapping cloth comprises:

[0007] Band body;

[0008] A hook and loop fastener portion, the hook and loop fastener portion comprising a first hook and loop fastener portion and a second hook and loop fastener portion disposed on the same surface of the strap body; and

[0009] A fixing ring is rotatably fixed to a fixing end of the strap body.

[0010] According to the above structure, the operator can quickly and effectively fix the hose wrap by simply pulling the wrapping body through the fixing ring and sticking it. At the same time, the hose wrap is not easy to loosen. In addition, the hose wrap has a simple and light structure and is easy to carry and store.

[0011] In some embodiments, the first hook and loop portions are respectively the hook surface and loop surface of a hook and loop tape that can be freely bonded and separated. According to the above structure, the hose wrapping cloth is easy to operate and has a light structure.

[0012] In addition, in some embodiments, the first hook and loop fastener is arranged at the free end of the wrapping body in a manner along the outer shape of the free end of the wrapping body, and the second hook and loop fastener is arranged at a distance from the first hook and loop fastener in the length direction of the wrapping body. According to the above structure, in the use state, the hose wrapping cloth can be completely attached to the fire hose until the end, which is convenient for the movement of the fire hose, and a space for contacting and fixing with the fixing ring can be formed between the first hook and loop fastener.

[0013] In addition, in some embodiments, the wrapping body has an inner waterproof layer, an outer waterproof layer, and an intermediate layer disposed between the inner waterproof layer and the outer waterproof layer. According to the above structure, the double waterproof layer can play a double waterproof role, thereby reliably preventing water from seeping from the leaking point to the outside of the hose wrapping when the hose wrapping is attached to the leaking point of the fire hose.

[0014] In addition, in some embodiments, a cross bar slidably connected to the frame of the fixing ring is provided inside the fixing ring. According to the above structure, the hose wrapping cloth between the cross bar and the frame can be clamped by the cross bar abutting against the frame, further improving the fixing effect.

[0015] In addition, in some embodiments, a clamping portion matching the shape of the frame is provided on the surface of the crossbar that contacts the frame, and the clamping portion may have a groove that can be engaged with the frame, or may be formed in a step shape that can be engaged with the frame. According to the above structure, the hose wrapping cloth between the crossbar and the frame can be clamped by the clamping portion engaging with the frame via the wrapping body, further improving the fixing effect.

[0016] In addition, in some embodiments, a cross bar fixedly connected to the frame of the fixing ring is provided inside the fixing ring, and the cross bar is provided on a side farther from the fire hose than the frame of the fixing ring that presses the fire hose in the thickness direction of the fire hose wrap. According to the above structure, when the fire hose wrap is tightened, the frame of the fixing ring can be pressed against the fire hose to clamp the fire hose wrap between the frame and the fire hose, and the tighter the fire hose wrap is, the stronger the pressing force of the frame on the fire hose wrap is, so the fixing effect can be further improved.

[0017] In addition, in some embodiments, a surface of the fixing ring in contact with the tape body is provided with a protrusion or a rough surface. According to the above structure, the friction between the fixing ring and the tape body can be increased, and the fixing effect can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the following embodiments are merely exemplary of the preferred structures of the present invention, and the scope of the present invention is not limited to these structures. In addition, for ease of description, the dimensions of each part are schematically indicated in each figure, and the proportions in the figure are sometimes inconsistent with the actual proportions.

[0027] Figure 1 It is a perspective view showing the overall structure of a hose cover according to one embodiment of the utility model. Figure 2 2 is a schematic plan view showing the hose wrapping cloth of this embodiment in an unfolded state. Figure 1 and Figure 2 As shown, the hose wrap of this embodiment includes a wrapping body 1 as the main body of the hose wrapping, a hook and loop portion 2 and a fixing ring 3 provided on the wrapping body 1 .

[0028] The wrapping body 1 is a long strip-shaped body used to wrap the fire hose and pressurize and seal the leaking point. One end of the wrapping body 1 in the longitudinal direction is fixed with a fixing ring 3 described later, and the other end is a free end. The front end can be set as, for example Figure 1 The rounded shape shown or Figure 2 The arc shape shown, etc.

[0029] Figure 3 1 is a schematic cross-sectional view showing the structure of the tape body 1. Figure 3 As shown, the wrapping body 1 may be a sandwich structure having an inner waterproof layer 11, an outer waterproof layer 12, and an intermediate layer 13 disposed between the inner waterproof layer 11 and the outer waterproof layer 12. The intermediate layer 13 may be made of a material such as polyester. The inner waterproof layer 11 and the outer waterproof layer 12 may be integrated with the intermediate layer 13 by coating, bonding, laminating, etc., and the double-layer waterproof layer may play a double waterproof role, thereby reliably preventing water from seeping from the leaking point to the outside of the hose wrapping cloth when the hose wrapping cloth is attached to the leaking point of the fire hose.

[0030] The width and length of the strap body 1 can be appropriately changed according to the diameter of the fire hose, water pressure, etc. For example, from the perspective of balance between portability and operability, the length can be set to about 5 times the width.

[0031] The hook and loop fastener portion 2 is a first fixing portion for connecting and fixing the two ends of the strap body 1. Figure 1 and Figure 2 As shown, the hook and loop fastener portion 2 includes a first hook and loop fastener portion 2A and a second hook and loop fastener portion 2B, and the first hook and loop fastener portion 2A and the second hook and loop fastener portion 2B are arranged on a first surface on the same side of the strap body 1 .

[0032] In this embodiment, the first hook and loop portions 2A and 2B are respectively the hook and loop surfaces of the hook and loop tape that can be freely bonded and separated. The first hook and loop portion 2A is arranged at the free end of the wrapping body 1 in a manner along the outer shape of the free end of the wrapping body 1, so that in the use state, the hose wrapping cloth can be completely attached to the fire hose until the end, which is convenient for the movement of the fire hose. The second hook and loop portion 2B is arranged at a distance from the first hook and loop portion 2A in the length direction of the wrapping body 1, so as to form a space for contacting and fixing with the fixing ring 3 described later between the first hook and loop portion 2A and the second hook and loop portion 2B.

[0033] The width and length of the hook and loop portion 2 can be appropriately changed according to the diameter of the fire hose, water pressure, etc. For example, from the perspective of bonding stability, the length of the hook and loop portion 2 can be set so that the length of the effective bonding area between the first hook and loop portion 2A and the second hook and loop portion 2B reaches more than one-fourth of the circumference of the cross section of the fire hose when in use. In addition, the hook and loop portion 2 can be used, for example, with a shear strength of 11.0 N / cm 2 The above strong Velcro with a peel strength of 2.0 N / cm or more can also be selected as a waterproof Velcro.

[0034] The fixing ring 3 is a second fixing part for connecting and fixing both ends of the strap body 1. The fixing ring 3 is fixed to the fixed end of the strap body 1 in a rotatable manner.

[0035] When sealing the leaking point of the fire hose, the operator places the fire hose at the leaking point on the second side of the hose wrapping cloth opposite to the first side, and pulls the free end of the wrapping body 1 from the second side of the fixing ring 3 through the middle space of the fixing ring 3 to the first side of the fixing ring 3, and applies tension to the wrapping body 1 with the fixing ring 3 as a fulcrum. At the same time, observe whether there is still leakage at the leaking point, and after the wrapping body 1 is tightened to the maximum extent until there is no leakage, overlap the pulled-out part of the wrapping body 1 with the part surrounding the fire hose, and fix it by sticking the first hook and loop part 2A of the hook and loop part 2 to the second hook and loop part 2B.

[0036] According to the hose wrapping cloth of the above structure, the hose wrapping cloth can be quickly and effectively fixed by simply performing the simple operation of tightening and sticking the wrapping body 1 passing through the fixing ring 3, thereby greatly simplifying the operation steps and saving operation time.

[0037] Since a fixing ring 3 as a second fixing part is provided in addition to the hook and loop part 2 as the first fixing part, the operator can use the fixing ring 3 to fold the strap body 1, and use the fixing ring 3 as a fulcrum to tighten the hose wrapping cloth in the most convenient force application direction, so that the tensioning force can be applied to the maximum extent to pressurize and seal the leaking point, eliminate the gap between the fire hose and the hose wrapping cloth, and make the two fit tightly, thereby improving the sealing effect of the leaking point of the fire hose. In addition, when the fixing ring is not provided and the hose wrapping cloth is tightened along the circumferential direction of the fire hose by manpower alone, the hose wrapping cloth is easy to loosen and the leaking point cannot be pressurized and sealed.

[0038] Furthermore, the hose wrap of the present embodiment has a simple and light structure. When the hose wrap is folded for storage, the Velcro portion 2 and the fixing ring 3 can be stacked in close proximity with the wrapping body 1, occupying a small storage space, making it convenient for operators to carry and move.

[0039] In the above-mentioned embodiment, the simple annular fixing ring 3 is used as the second fixing portion, but a fixing ring having another structure may be used as the second fixing portion.

[0040] Figure 4 and Figure 5 1 is a diagram showing the structure of a fixing ring 3A according to a modification example 1 of the present invention. Figure 4 and Figure 5As shown, the fixing ring 3A includes a frame and a cross bar, and a cross bar 31 is arranged inside the frame of the fixing ring 3A. Both ends of the cross bar 31 are respectively connected to the frame of the fixing ring 3A in a manner that they can slide along the two longitudinal frames of the fixing ring 3A, so that when the free end of the wrapping body 1 is passed over the cross bar 31 from the second side of the cross bar 31 and then pulled out to the second side of the cross bar 31, under the action of the pulling force of the wrapping body 1, the cross bar 31 slides to abut against the transverse frame 32, and the wrapping body 1 between the cross bar 31 and the frame 32 is clamped and fixed.

[0041] Figure 6 2 is a diagram showing the structure of a fixing ring 3B according to a second modification of the present invention. Figure 6 As shown, in the above-mentioned embodiment, a clamping portion 33 matching the shape of the frame 32 may also be provided on the surface of the cross bar 31 that abuts against the frame 32 .

[0042] In this embodiment, the clamping portion 33 has a groove whose inner diameter is slightly larger than the outer diameter of the frame 32, and the groove can be engaged with the frame 32 to clamp the band body 1. Therefore, when the free end of the band body 1 is passed over the cross bar 31 from the second surface side of the cross bar 31 and then pulled out to the second surface side of the cross bar 31, under the action of the pulling force of the band body 1, the cross bar 31 slides to abut against the frame 32, and the clamping portion 33 of the cross bar 31 engages with the frame 32 through the band body 1 to clamp and fix the band body 1 between the cross bar 31 and the frame 32.

[0043] Furthermore, the clamping portion is not limited to having a groove, and may be formed in other shapes that can engage with the frame 32, such as a step shape that is offset from the frame 32 in the thickness direction of the strap body 1.

[0044] Figure 7 2 is a diagram showing the structure of a fixing ring 3C according to a third modification of the present invention. Figure 7 As shown, a cross bar 34 whose two ends are fixedly connected to the two longitudinal frames of the fixing ring 3C can also be provided inside the fixing ring 3C, and the cross bar 34 is provided on a side farther from the fire hose than the transverse frames 35 of the fixing ring 3C. Thus, when the wrapping body 1 hung on the cross bar 34 is tightened, the fixing ring 3C is pressed against the fire hose under the action of the tension, and at this time, the frame 35 clamps the wrapping body 1 between it and the fire hose, and the tighter the wrapping body 1 is, the stronger the pressing force of the frame 35 on the wrapping body 1 is, so that the fixing ring 3C can fasten the wrapping body 1.

[0045] In addition, in the above-mentioned embodiments, protrusions such as teeth or rough surfaces may be provided on the surface of the fixing ring in contact with the wrapping body 1 to increase the friction between the fixing ring and the wrapping body 1 and further improve the fixing effect.

[0046] The above embodiments show preferred embodiments of the present invention, but the present invention is not limited thereto. It should be understood that the above embodiments are merely exemplary and non-restrictive, and various obvious or equivalent modifications, substitutions and combinations that can be made by those skilled in the art for the above details without departing from the gist of the present invention will be included in the scope of the claims of the present invention.
