Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a high-toughness fire fighting hose that is resistant to freezing and cracking. Background Art

[0002] A fire hose is a flexible pipe used to transport flame-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and covered with flax woven fabric on the outside. With the development of science and technology, fire hoses have also been technically improved. However, the new fire hoses in existing technology have poor toughness. When firefighters drag and stretch the fire hoses, the fire hoses are easily damaged and need to be replaced frequently, resulting in a waste of resources. In addition, the existing fire hoses are prone to becoming tangled after being reeled, which requires firefighters to spend time and effort to re-reel them.

[0003] Therefore, it is necessary to provide a new high-toughness fire hose that prevents freezing and cracking to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-toughness fire hose that is resistant to freezing and cracking.

[0005] The utility model provides a high-toughness fire hose that prevents frost cracking, comprising a belt body, wherein the upper belt surface of the belt body is fixedly embedded with two symmetrically distributed rubber ribs, and the lower belt surface of the belt body is provided with two symmetrically distributed arc grooves;

[0006] The belt body includes an inner layer of isobutylene rubber, and a woven layer is fixedly embedded on the outer surface of the inner layer of isobutylene rubber, and a glass wool felt layer is fixedly embedded on the outer surface of the woven layer, and a low-temperature resistant silicone rubber layer is fixedly provided on the outer surface of the glass wool felt layer, and an external rubber layer is compounded on the low-temperature resistant silicone rubber layer, and a polyvinyl chloride insulation layer is fixedly embedded on the external rubber layer.

[0007] Preferably, the rubber ribs are fixedly embedded in the upper surface of the external rubber layer, and the arc-shaped grooves are opened on the lower surface of the external rubber layer.

[0008] Preferably, the polyvinyl chloride insulation layer is distributed on the outside of the external rubber layer and adheres to the rubber ribs and arc grooves.

[0009] Preferably, a wear-resistant layer is sewn on the belt body between the two rubber ribs.

[0010] Preferably, the wear-resistant layer is made of toughened aluminum oxide material.

[0011] Preferably, the braided layer is woven from nylon, cotton or polyester.

[0012] Preferably, the rubber ribs correspond to the arcuate grooves one by one, and the rubber ribs and the arcuate grooves are interference fit.

[0013] Preferably, the belt body is sprayed with RTV anti-fouling flashover paint.

[0014] Compared with the related art, the high-toughness fire hose provided by the utility model has the following features:

[0015] Beneficial effects:

[0016] 1. The internal isobutylene rubber layer and the external rubber layer provided in the present invention make the overall structure of the fire hose more flexible and have a better rebound effect, thereby effectively preventing the hose from being damaged due to bending. At the same time, the structural design of the glass wool felt layer, the low-temperature resistant silicone rubber layer and the polyvinyl chloride insulation layer effectively prevents the inner layer of the fire hose from freezing and cracking, thereby avoiding the hidden danger of damage and freezing of the fire hose caused by the temperature drop of the inner layer due to the low external temperature.

[0017] 2. When the fire hose is rolled up, the rubber ridges on the outer surface of the belt body are engaged with the arc grooves on the inner surface of the belt body, so that the rolled-up belt body is fixed to each other and will not be easily scattered. When the fire hose is needed, the belt body with a disc-shaped structure after rolling up is rolled outward, so that the rubber ridges in the belt body slide out of the corresponding arc grooves, and the fire hose can be quickly distributed. Since the outer surface of the belt body contacts the ground after laying, the two rubber ridges support the belt body, effectively reducing the wear between the belt body and the ground.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figures 1 to 2 The embodiment of the present invention provides a high-toughness fire hose that is resistant to frost cracking. The high-toughness fire hose that is resistant to frost cracking includes a belt body 1 and rubber ribs 2.

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The belt body 1 includes an inner layer of isobutylene rubber 101, and a braided layer 102 is fixedly embedded on the outer surface of the inner layer of isobutylene rubber 101. The braided layer 102 is woven from nylon, cotton, and polyester materials, and a glass wool felt layer 103 is fixedly embedded on the outer surface of the braided layer 102. A low-temperature resistant silicone rubber layer 104 is fixedly provided on the outer surface of the glass wool felt layer 103, and an external rubber layer 105 is compounded on the low-temperature resistant silicone rubber layer 104, and a polyvinyl chloride insulation layer 106 is fixedly embedded on the external rubber layer 105.

[0025] It should be noted that the isobutylene rubber inner layer 101 and the outer rubber layer 105 make the overall structure of the fire hose more flexible and have a better rebound effect, thereby effectively preventing the belt body 1 from being damaged due to bending. At the same time, the structural design of the glass wool felt layer 103, the low-temperature resistant silicone rubber layer 104 and the polyvinyl chloride insulation layer 106 effectively prevents the inner layer of the fire hose from freezing and cracking, thereby avoiding the hidden danger of damage and freezing of the fire hose caused by the temperature drop of the inner layer of the fire hose due to the low external temperature.

[0026] The belt body 1 is sprayed with RTV anti-fouling flashover paint, thereby preventing external sewage from penetrating into the fire hose and causing damage to the fire hose.

[0027] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The upper belt surface of the belt body 1 is fixedly embedded with two symmetrically distributed rubber ribs 2, and the lower belt surface of the belt body 1 is provided with two symmetrically distributed arc grooves 3, the rubber ribs 2 and the arc grooves 3 correspond one to one, and the rubber ribs 2 and the arc grooves 3 are interference fit, and the rubber ribs 2 are fixedly embedded in the upper surface of the external rubber layer 105, the arc grooves 3 are provided on the lower surface of the external rubber layer 105, and the polyvinyl chloride insulation layer 106 is distributed on the outside of the external rubber layer 105 and adheres to the rubber ribs 2 and the arc grooves 3.

[0028] It should be noted that: when the fire hose is rolled up, the rubber ribs 2 on the outer surface of the belt body 1 are snapped into the arc grooves 3 on the inner surface of the belt body 1, so that the rolled-up belt body 1 is fixed to each other and will not be easily scattered. When the fire hose is needed, the belt body 1 with a disc-shaped structure after rolling up is rolled outward, so that the rubber ribs 2 in the belt body 1 slip out of the corresponding arc grooves 3, and the fire hose can be quickly distributed. Since the outer surface of the belt body 1 contacts the ground after laying, the two rubber ribs 2 support the belt body 1, effectively reducing the wear between the belt body 1 and the ground.

[0029] A wear-resistant layer 107 is sewn on the belt body 1 between the two rubber ribs 2, and the wear-resistant layer 107 is made of toughened aluminum oxide material, which improves the wear resistance of the belt body 1 when it contacts the ground.

[0030] The working principle of the high-toughness fire hose that prevents frost cracking provided by the utility model is as follows:

[0031] The isobutylene rubber inner layer 101 and the outer rubber layer 105 make the overall structure of the fire hose more flexible and have a better rebound effect, thereby effectively preventing the belt body 1 from being damaged due to bending. At the same time, the structural design of the glass wool felt layer 103, the low-temperature resistant silicone rubber layer 104 and the polyvinyl chloride insulation layer 106 effectively prevents the inner layer of the fire hose from freezing and cracking, avoiding the hidden danger of damage and freezing of the fire hose caused by the temperature drop of the inner layer due to the low external temperature.

[0032] When the fire hose is rolled up, the rubber ribs 2 on the outer surface of the belt body 1 are engaged with the arc grooves 3 on the inner surface of the belt body 1, so that the rolled-up belt body 1 is fixed to each other and will not be easily scattered. When the fire hose is needed, the belt body 1 with a disc-shaped structure after rolling up is rolled outward, so that the rubber ribs 2 in the belt body 1 slip out of the corresponding arc grooves 3, and the fire hose can be quickly distributed. Since the outer surface of the belt body 1 contacts the ground after laying, the two rubber ribs 2 support the belt body 1, effectively reducing the wear between the belt body 1 and the ground.

[0033] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
