[0022] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] See also Figure 1-Figure 5 A heat-resistant rubber composite hose includes a hose body 1. The hose body 1 includes an inner bellows 11, a heat-resistant layer 13, a reinforcement layer 14, and an anti-aging layer 15. The heat-resistant layer 13 is sleeved on the outer wall of the inner bellows 11, the reinforcement layer 14 is sleeved on the outer wall of the heat-resistant layer 13, and the anti-aging layer 15 is sleeved on the outer wall of the reinforcement layer 14. Both ends of the inner bellows 11 are equipped with a connecting structure 2, which includes a joint 21, a connecting ring 22, a sealing ring 23 and a flange ring 24. The outer walls of the joint 21 and the connecting ring 22 are provided with a shock-absorbing structure 25 arranged in a ring with equal intervals. By wrapping the heat-resistant layer, the reinforcement layer and the anti-aging layer on the outer wall of the inner bellows, the heat resistance of the hose body is improved, and the compressive strength and anti-aging performance are also improved.

[0025] In this embodiment, the thickness of the heat-resistant layer 13 is 1 mm, and the heat-resistant layer 13 is made of silicone material. Silicone has excellent heat resistance and no odor, which is convenient for improving the overall heat resistance of the hose body 1.

[0026] Then, the inner wall of the inner bellows 11 is provided with a thread groove 110, and the joint 21 is threadedly connected to the inner bellows 11 through the external thread 211 provided on its outer wall. The interior of the joint 21 is hollow, and it is connected to the inner bellows 11 through the joint 21 without affecting the flow of internal liquid while having good sealing performance.

[0027] Furthermore, an inner spiral steel wire 12 is fixedly connected to the inner wall of the inner bellows 11, and an outer spiral steel wire 16 is fixedly connected to the outer wall of the anti-aging layer 15. The inner and outer layers of spiral steel wires can reduce the uneven force and impact vibration effects of the external thread 211, improve the fatigue strength of the external thread 211, and reduce the wear and corrosion resistance of the thread groove 110.

[0028] In this embodiment, the shock-absorbing structure 25 includes a telescopic rod 253 and a spring 254 mounted on the outside of the telescopic rod 253. The two ends of the telescopic rod 253 are respectively hinged with a first rotating shaft 252 and a second rotating shaft 255. After the joint 21 and the connecting ring 22 are impacted, the first rotating shaft 252 rotates, and at the same time, the telescopic rod head of the telescopic rod 253 is extended, and the spring 362 is stretched to complete the absorption of the impact.

[0029] It should be noted that the first rotating shaft 252 is fixed on the side wall of the connecting ring 22, and the side wall of the connecting ring 22 is installed with a connecting piece 251 for fixing the first rotating shaft 252, and the second rotating shaft 255 is fixed on the side wall of the joint 21 to facilitate normal use of the structure.

[0030] It should be supplemented that a buckle 221 is provided on the surface of the connecting ring 22 , and the connecting ring 22 is snapped onto the surface of the sealing ring 23 via the buckle 221 , which facilitates normal use of the structure.

[0031] Finally, the thickness of the reinforcement layer 14 is 1.5 mm. The reinforcement layer 14 is made of synthetic fiber material. The reinforcement layer 14 can provide pressure-bearing strength for the hose body 1, facilitating long-term use of the hose body 1.

[0032] Working principle: When the user uses this heat-resistant rubber composite hose, the inner bellows 11, the heat-resistant layer 13, the reinforcement layer 14 and the anti-aging layer 15 are wrapped layer by layer, so that the hose body 1 has good heat resistance. The joint 21 is tightened with the inner bellows 11, and then the shock-absorbing structure 25 between the joint 21 and the connecting ring 22 will play a role, reducing damage caused by external impact. The flange ring 24 is provided for easy connection with the outside. The inner and outer layers of spiral steel wire can reduce the uneven force and impact vibration of the external thread 211, improve the fatigue strength of the external thread 211, reduce the wear and corrosion resistance of the thread groove 110, and enable the joint and the inner bellows 11 to be used for a long time, thereby improving the practicality of the product.

[0033] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model.
