Description

Technical Field

[0001] The utility model belongs to the technical field of fuel tank accessories, and specifically relates to an integrated strap for fixing a heavy-duty vehicle fuel tank. Background Art

[0002] The fuel tank is an important component in an automobile for storing fuel. It is usually located at the bottom or rear of the vehicle and is connected to the engine through a fuel pipe to provide the required fuel for the engine. The safety of the fuel tank is one of the key issues to be considered in automobile design. To prevent safety hazards such as fuel leakage and fire, the fuel tank usually adopts multiple protection measures, including anti-leakage valves, fireproof materials, explosion-proof devices, etc. At the same time, in the event of an accident such as a collision of the vehicle, the fuel tank also needs to have sufficient strength and stability to avoid dangerous situations such as rupture or explosion.

[0003] The fuel tank strap plays an important role in automobile components. It is mainly used to connect and fix the fuel tank cap to ensure that the fuel tank cap will not accidentally fall off during vehicle driving. Through its design, the fuel tank strap connects the fuel tank cap to the vehicle body or the fuel tank itself to ensure that the fuel tank cap can be firmly held in place in the closed state. During vehicle driving, the fuel tank strap can effectively prevent the fuel tank cap from loosening or falling off due to vibration, bumping or other external factors, thus ensuring the safety of the vehicle and passengers.

[0004] The fuel tank strap is generally only used on heavy-duty vehicles. Heavy-duty vehicles refer to those vehicles mainly used for transporting a large amount of goods and passengers, usually having a large load capacity and passenger capacity; since the fuel tanks on heavy-duty vehicles are all of large capacity, in order to achieve safety in structure, the fuel tank strap is used outside the fuel tank. The fuel tank strap generally uses a metal material with high structural strength, and there will be a situation of slipping during the use of the fuel tank strap, resulting in a large amount of wear between the strap and the fuel tank. Content of the Utility Model

[0005] To solve the problem of large wear between the fuel tank strap and the fuel tank, the utility model provides an integrated strap for fixing a heavy-duty vehicle fuel tank.

[0006] The utility model is realized through the following technical solutions:

[0007] An integrated strap for fixing a heavy-duty vehicle fuel tank includes a strap body. One end of the strap body is provided with a bushing hole, and the other end is provided with a tension pin hole; it also includes a strap cushion belt arranged between the strap body and the fuel tank, and the strap cushion belt is installed on one side of the strap body.

[0008] Both ends of the drawband body are respectively provided with a bushing hole and a tension pin hole for fixing both ends of the drawband body to the vehicle frame, thereby achieving enhanced fixation of the fuel tank. The drawband cushion can be located between the fuel tank and the drawband body during use, increasing the contact area between the two, helping to prevent the drawband body from slipping on the fuel tank, and at the same time, the drawband cushion forms a buffer in the middle to avoid increased wear between the two.

[0009] A further improvement of the present utility model is that the above-mentioned drawband body is embedded in the drawband cushion. This helps to improve the integrity of the drawband cushion and the drawband body, and maintain the stability of the drawband cushion when the drawband body is in use.

[0010] A further improvement of the present utility model is that the long sides of the above-mentioned drawband cushion are respectively provided with card edges that extend upward and are folded inward at a right angle. This facilitates the assembly operation.

[0011] A further improvement of the present utility model is that the above-mentioned drawband cushion is made of rubber material.

[0012] A further improvement of the present utility model is that the above-mentioned bushing hole and tension pin hole are both obtained by folding one end of the drawband body inward and then riveting.

[0013] A further improvement of the present utility model is that the above-mentioned riveting method is non-riveting. This can reduce the fatigue strength of the drawband body after riveting and improve the durability.

[0014] A further improvement of the present utility model is that a bushing is provided in the above-mentioned bushing hole. An annular groove is formed on the side surface of the bushing, and an extrusion protrusion that cooperates with the annular groove is formed on the inner wall of the bushing hole. The extrusion protrusion cooperates with the annular groove to prevent the bushing from slipping outwards.

[0015] A further improvement of the present utility model is that a tension pin is provided in the above-mentioned tension pin hole. Anti-slip protrusions are respectively provided at both ends of the tension pin, and the anti-slip protrusions prevent the tension pin from slipping out of the tension pin hole.

[0016] A further improvement of the present utility model is that the width of the above-mentioned drawband body is d, and 50mm ≤ d ≤ 90mm.

[0017] A further improvement of the present utility model is that the thickness of the above-mentioned drawband body is a, and 2mm ≤ a ≤ 4mm.

[0018] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows: sleeve holes and tension pin holes are respectively provided at both ends of the strap body for fixing both ends of the strap body on the vehicle frame, thereby realizing the enhanced fixation of the fuel tank; the strap cushion can be located between the fuel tank and the strap body during use, increasing the contact area between the two, helping to prevent the strap body from moving on the fuel tank, and at the same time, the strap cushion forms a buffer in the middle to avoid the aggravation of wear between the two.
