[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] refer to Figure 1-4 A fuel dispenser hose protective cover comprises a fuel dispenser hose 1, a protective rubber cover assembly 2 installed on the outside of the fuel dispenser, and a clamp assembly 3 installed at both ends of the fuel dispenser hose 1, wherein the protective rubber cover assembly 2 is provided with an inner lining layer 201, a shock-absorbing layer 202, an insulating layer 203, a copper wire reinforcement layer 204, an anti-ultraviolet layer 205, a protective layer 206 and an outer covering layer 207 from bottom to top, and the inner lining layer 201, the shock-absorbing layer 202, the insulating layer 203, the copper wire reinforcement layer 204, the anti-ultraviolet layer 205, the protective layer 206 and the outer covering layer 207 are all bonded and tightly combined together by thermal bonding or other processes to form a protective layer. It forms a sturdy and flexible protective cover that can adapt to various usage environments and conditions. The clamp assembly 3 includes a clamp strip 301, one end of which is fixedly provided with a box body 302, and a positioning groove 303 is provided on the surface of the clamp strip 301. A rotating rod 304 is rotatably provided inside the box body 302, and a spiral blade 305 is fixedly provided on the outside of the rotating rod 304. After the protective rubber sleeve assembly is installed to the outside of the hose, the screw head is twisted with the help of an external tool, so that the clamp strip is tightly fitted to the hose after the tightness is adjusted by rotating the spiral blade and the positioning groove, thereby enhancing the connection strength between the two and avoiding the problem of falling off due to dragging.

[0024] Example 1: The inner lining layer 201 is made of polyethylene, which is used to reduce the friction between the hose and the copper wire and protect the surface of the hose. The insulating layer 203 is made of rubber, which is used to insulate and further protect the copper wire layer to prevent damage caused by external factors. The protective layer 206 is made of polyurethane to resist external wear, chemicals and ultraviolet radiation. The outer covering layer 207 is made of Teflon to provide additional protection and aesthetics. Copper wire is provided inside the copper wire reinforcement layer 204. The copper wire is used to conduct static electricity, ensure safe operation, and provide strength and pressure resistance. The shock-absorbing layer 202 has a hollow structure inside and is filled with air to increase the shock-absorbing layer and reduce damage caused by vibration during refueling. The anti-ultraviolet layer 205 is made of polyvinyl chloride to improve the anti-ultraviolet performance of the outer covering and prevent the material from aging due to long-term exposure to sunlight.

[0025] Example 2: The other end of the clamp strip 301 is movably arranged inside the box body 302, and a number of positioning grooves 303 are provided. A screwing head 306 is fixedly provided at the other end of the rotating rod 304, and the spiral blade 305 and the positioning groove 303 are snap-fitted. The rotational positioning between the spiral blade and the positioning groove is used to control the connection strength between the hose and the protective sleeve.

[0026] Working principle: The protective cover is made of a composite of multiple layers of materials and is tightly wrapped around the outside of the fuel dispenser hose to form a strong and flexible protective layer. The inner lining layer 201 is made of polyethylene to reduce the friction between the hose and the copper wire and protect the hose surface; the shock-absorbing layer 202 is a hollow structure filled with air to reduce shock and reduce vibration damage during refueling; the insulating layer 203 is made of rubber to protect the copper wire reinforcement layer 204 to prevent damage caused by external factors. The copper wire reinforcement layer 204 provides strength and pressure resistance to ensure that the protective cover is not easily damaged during refueling. The anti-ultraviolet layer 205 is made of polyvinyl chloride to improve the anti-ultraviolet performance of the outer layer and prevent material aging. 206 is made of polyurethane to resist external wear, chemicals and ultraviolet radiation. The outer covering 207 is made of Teflon to provide additional protection and beauty. The clamp assembly 3 achieves a tight connection between the protective sleeve and the hose through the cooperation of the clamp strip 301 and the spiral blade 305. One end of the clamp strip 301 is fixed to the box body 302, and the other end is movably arranged inside the box body. The rotating rod 304 is twisted by the screw head 306 to rotate the spiral blade 305 in the positioning groove 303, thereby adjusting the tightness of the clamp strip, making the protective sleeve fit closely to the hose, enhancing the connection strength and avoiding falling off. This design enables the protective sleeve to adapt to various usage environments and conditions, ensuring the safety and convenience of refueling operations.
