Description

Technical Field

[0001] This utility model belongs to the technical field of fuel tank clamp forgings, specifically relating to a fuel tank clamp forging with strong fastening properties. Background Technology

[0002] Fuel tank clamp forgings are metal components used to secure fuel tanks in automobiles, motorcycles, construction machinery, and other equipment. They are typically made of materials such as steel and aluminum alloys through a forging process. Their main function is to ensure the stability and safety of the fuel tank during vehicle operation, preventing displacement, leakage, and other problems caused by vibration, collisions, or other factors.

[0003] Currently, existing fuel tank band forgings are typically used by fitting two symmetrically distributed fuel tank bands onto the outer wall of the fuel tank, and then tightening the bolts to secure the fuel tank. However, traditional fuel tank band forgings are often made of metal, so the metal surface of the band forging will contact the outer wall of the fuel tank during fitting. However, because the friction of the metal surface of the band forging is relatively weak, if the fuel tank vibrates after tightening, the bands may loosen, thereby reducing safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fuel tank clamp forging with strong fastening, aiming to solve the problem that existing fuel tank clamp forgings, when used, usually involve fitting two symmetrically distributed fuel tank clamps onto the outer wall of the fuel tank, and then tightening the bolts to tighten the two fuel tank clamps to achieve fuel tank fastening. However, traditional fuel tank clamp forgings are often made of metal, so when fitting, the metal surface of the clamp forging will contact the outer wall of the fuel tank. However, because the friction of the metal surface of the clamp forging is weak, if the fuel tank vibrates after fastening, the clamps may loosen, thereby reducing safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forged fuel tank band with strong fastening, comprising a first fuel tank band and a second fuel tank band, wherein the first fuel tank band and the second fuel tank band are symmetrically distributed, and fastening bolts penetrate the ends of the first fuel tank band and the second fuel tank band, wherein fastening nuts are threadedly connected to the through ends of the fastening bolts.

[0006] The inner walls of the first fuel tank clamp and the second fuel tank clamp have two first arc-shaped grooves, and rubber strips are bonded to the inner sides of the two first arc-shaped grooves. The inner walls of the first fuel tank clamp and the second fuel tank clamp have second arc-shaped grooves, and nylon strips are bonded to the inside of the second arc-shaped grooves.

[0007] As a preferred embodiment of the fuel tank band forging with strong fastening properties according to this utility model, the second arc-shaped groove is located between the two first arc-shaped grooves.

[0008] As a preferred embodiment of the fuel tank clamp forging with strong fastening properties according to this utility model, the nylon strip has the same thickness and length as the two rubber strips.

[0009] As a preferred embodiment of the strong fastening forging of the oil tank band according to this utility model, a protective cover is installed at the end of the second tank band, and two fixing blocks are fixedly connected to the top of the protective cover. Limiting grooves are formed on the outer walls of the two fixing blocks. A mounting base is fixedly connected to the end of the second tank band, and a spring is movably connected inside the mounting base. Movable blocks are connected to both ends of the spring. A limiting pin is connected to one end of the movable block, and a lever is fixedly connected to the top of the movable block.

[0010] As a preferred embodiment of the fuel tank clamp forging with strong fastening properties according to this utility model, the two fixing blocks are symmetrically distributed at both ends of the mounting base.

[0011] As a preferred embodiment of the oil tank clamp forging with strong fastening properties according to this utility model, the size of the limiting groove is adapted to one end of the limiting pin.

[0012] As a preferred embodiment of the forged oil tank band with strong fastening properties according to this utility model, the protective cover can form an elastic engagement structure with the second tank band through a fixed block, a limiting slot, a mounting base, a spring, a movable block, a limiting pin, and a lever block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By creating two first arc-shaped grooves and one second arc-shaped groove on the inner walls of the first and second tank bands, and then bonding a rubber strip into the first arc-shaped groove and a nylon strip into the second arc-shaped groove, when the first and second tank bands are fitted onto the outer wall of the tank and the bolts are tightened, the first and second tank bands will squeeze the rubber strip and nylon strip, thereby increasing the friction and fastening between the band forging and the tank, and also playing a role in buffering and shock absorption, reducing the occurrence of loosening of the band forging caused by vibration.

[0015] By moving the movable block with the lever, the limit pin retracts. Then, the protective cover covers the fastening nut, and the two fixed blocks are positioned at both ends of the mounting base. At this time, the lever is released, allowing the limit pin to pop out and insert into the limit slot under the action of the spring. Thus, the protective cover can protect the connection end of the fastening bolt and the fastening nut. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a forged oil tank band with strong fastening, including a first oil tank band 1 and a second oil tank band 2, the first oil tank band 1 and the second oil tank band 2 are symmetrically distributed, and fastening bolts 3 pass through the ends of the first oil tank band 1 and the second oil tank band 2, and fastening nuts 4 are threadedly connected to the through end of the fastening bolts 3.

[0025] The inner walls of the first fuel tank band 1 and the second fuel tank band 2 have two first arc-shaped grooves 5, and rubber strips 6 are bonded to the inner sides of the two first arc-shaped grooves 5. The inner walls of the first fuel tank band 1 and the second fuel tank band 2 have second arc-shaped grooves 7, and nylon strips 8 are bonded to the inside of the second arc-shaped grooves 7.

[0026] Preferably, the second arc-shaped groove 7 is located between the two first arc-shaped grooves 5, and the nylon strip 8 has the same thickness and length as the two rubber strips 6.

[0027] In practical use, two first arc-shaped grooves 5 and one second arc-shaped groove 7 are opened on the inner walls of the first tank band 1 and the second tank band 2. Then, the rubber strip 6 is glued into the first arc-shaped groove 5, and the nylon strip 8 is glued into the second arc-shaped groove 7. When the first tank band 1 and the second tank band 2 are fitted onto the outer wall of the tank and the bolts are tightened, the first tank band 1 and the second tank band 2 will squeeze the rubber strip 6 and the nylon strip 8, thereby increasing the friction and fastening between the band forging and the tank. It can also play a role in buffering and shock absorption, reducing the occurrence of loosening of the band forging caused by vibration.

[0028] It should be noted that the rubber strip 6 has excellent elasticity and can quickly return to its original shape after being squeezed or stretched by external force. This allows the rubber strip 6 to adapt well to objects of different shapes and sizes. In the fuel tank band, it can fill the gap between the band and the fuel tank, providing a tight fit. It can also absorb vibration and impact energy, reduce the generation and propagation of noise, reduce the noise generated by the fuel tank due to vibration, and reduce the damage of vibration to the band and the fuel tank.

[0029] Nylon strip 8 has high strength and rigidity, and can withstand large tensile and compressive forces without easily deforming. In the fuel tank strap, it can help the strap bear part of the weight and external force from the fuel tank, enhance the overall stability, and has high surface hardness and excellent wear resistance. Even under long-term use and friction, it can maintain good shape and performance, and is not prone to wear, cracking and other problems, which can extend the service life of the strap.

[0030] Preferably, a protective cover 9 is installed at the end of the second box strap 2. Two fixing blocks 10 are fixedly connected to the top of the protective cover 9. Limiting slots 11 are opened on the outer walls of the two fixing blocks 10. A mounting base 12 is fixedly connected to the end of the second box strap 2. A spring 13 is movably connected inside the mounting base 12. Movable blocks 14 are connected to both ends of the spring 13. A limiting pin 15 is connected to one end of the movable block 14. A lever 16 is fixedly connected to the top of the movable block 14. The two fixing blocks 10 are symmetrically distributed at both ends of the mounting base 12. The size of the limiting slot 11 is adapted to the size of one end of the limiting pin 15. The protective cover 9 can form an elastic engagement structure with the second box strap 2 through the fixing blocks 10, limiting slots 11, mounting base 12, spring 13, movable blocks 14, limiting pin 15, and lever 16.

[0031] In practical use, the movable block 14 is moved by the lever 16 to retract the limit pin 15, and then the protective cover 9 is put on the fastening nut 4, and the two fixing blocks 10 are respectively located at both ends of the mounting base 12. At this time, the lever 16 is released, so that the limit pin 15 can be popped out and inserted into the limit slot 11 under the action of the spring 13. Thus, the protective cover 9 can protect the connection end of the fastening bolt 3 and the fastening nut 4.

[0032] Conversely, by moving the movable block 14 with the toggle block 16, the limit pin 15 is retracted. At this time, one end of the limit pin 15 will disengage from the limit slot 11, and then it can be removed from the end of the second box band 2 by pulling the protective cover 9.

[0033] Working principle: First, the first tank clamp 1 and the second tank clamp 2 are fitted onto the outer wall of the tank. Then, by tightening the fastening bolts 3, the first tank clamp 1 and the second tank clamp 2 are compressed and squeezed. Two first arc-shaped grooves 5 and one second arc-shaped groove 7 are made on the inner walls of the first tank clamp 1 and the second tank clamp 2. A rubber strip 6 is then adhered to the first arc-shaped groove 5, and a nylon strip 8 is adhered to the second arc-shaped groove 7. When the first tank clamp 1 and the second tank clamp 2 are fitted onto the outer wall of the tank and the bolts are tightened, the first tank clamp 1 and the second tank clamp 2 will compress the rubber strip 6 and the nylon strip 8. 8. This improves the friction and fastening between the hoop forging and the oil tank, and also plays a role in buffering and shock absorption, reducing the loosening of the hoop forging caused by vibration. Furthermore, by moving the movable block 14 through the lever 16, the limit pin 15 is retracted, and then the protective cover 9 is put on the fastening nut 4, and the two fixing blocks 10 are respectively located at both ends of the mounting base 12. At this time, the lever 16 is released, so that the limit pin 15 can pop out under the action of the spring 13 and insert into the limit slot 11. Thus, the protective cover 9 can play a role in shielding and protecting the connection end of the fastening bolt 3 and the fastening nut 4.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
