In this way, when the hose outer sleeve 4 explodes, the hydraulic oil is also sealed in the closed space formed by the protective sleeve, and the safety is better.

[0025] As a preferred embodiment of the present application, the clamp 3 is a stainless steel clamp.

[0026] As a preferred embodiment of the present application, the high-temperature-resistant anti-leakage protective sleeve 5 has a double-layer structure, and comprises a heat insulation layer arranged inside and a protective layer arranged outside the heat insulation layer.

[0027] As a preferred embodiment of the present application, the heat insulation layer is a non-alkali glass fiber woven layer.

This design allows it to withstand ambient temperatures ranging from -65°C to 300°C, and instantaneous temperatures of 1200°C for up to 30 seconds. The high-temperature resistant, leak-proof protective sleeve 5 is soft, lightweight, and easy to install, without increasing the bending radius of the hose. Furthermore, this protective sleeve does not absorb water, and during use, it will not increase the weight of the hose assembly or cause external load damage to the hose. The high-temperature resistant, leak-proof protective sleeve 5 is 10% longer, preventing it from slipping off during hose assembly bending and thus maintaining its protective effect.

[0029] In a preferred embodiment of the present invention, the two ends of the high-temperature resistant and leak-proof protective sleeve 5 are closed by inward folding along the circumferential direction, and the ends of the high-temperature resistant and leak-proof protective sleeve 5 are provided with a pre-set length of slit along the axial direction.

[0030] In a preferred embodiment of this utility model, the preset length is 25mm. The cut is made by cutting along the axial direction with scissors after the closure is completed.

This ensures that even if the hose outer sleeve 4 bursts, the hydraulic oil will be sealed within the enclosed space created by the protective sleeve, improving safety. The high-temperature resistant leak-proof protective sleeve 5 is flexible, lightweight, and easy to install without increasing the hose's bending radius. Furthermore, this protective sleeve does not absorb water, preventing any increase in the weight of the hose assembly during use and avoiding external load damage to the hose. The sleeve 5 is 10% longer, preventing it from slipping off during hose assembly bending and thus maintaining its protective effect.
