Technical Field

[0001] This utility model relates to the field of motorcycle fuel tank connection technology, and in particular to a connection structure for a motorcycle fuel tank. Background Technology

[0002] The connection structure of a motorcycle fuel tank refers to a mechanical device composed of components such as metal brackets and fastening bolts, which securely and reliably installs the fuel tank in a designated position on the motorcycle frame. This structure meets the stability requirements under driving vibration conditions while also ensuring ease of maintenance and disassembly. It is a key functional component in the motorcycle fuel system that realizes the mechanical connection between the fuel tank and the entire vehicle.

[0003] The existing connection structure of motorcycle fuel tanks has different widths for different models, which causes the fuel tank to shift laterally within the frame mounting space. Over time, this shaking can lead to a decrease in the sealing performance of the joints and loosening of the threaded connections, thus causing fuel leakage. Utility Model Content

Through the cooperation of a sliding groove, connecting block, limiting plate, mounting groove, and friction pad, it effectively eliminates the assembly gap between the fuel tank and the frame mounting space, preventing lateral movement caused by vibration during vehicle operation. During long-term use, it maintains a stable clamping force, avoiding fuel leakage problems caused by decreased sealing performance of the fuel pipe joint and loosening of threaded connections due to continuous shaking.

[0005] This utility model also provides a connection structure for a motorcycle fuel tank as described above, including a housing. A limiting component is provided at the lower end of the housing. The limiting component includes two sliding grooves formed at the lower end of the housing. A connecting block is slidably connected inside the sliding grooves. A limiting plate is fixedly connected to the lower end of the connecting block. An installation groove is formed on the inner wall of the limiting plate. A friction pad is fixedly connected to the inner wall of the installation groove. Through the cooperation of the sliding grooves, connecting blocks, limiting plates, installation grooves, and friction pads, the assembly gap between the fuel tank and the frame mounting space can be effectively eliminated, preventing lateral movement caused by vibration during vehicle operation.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a connection structure for a motorcycle fuel tank, comprising a housing 100. A limiting component 200 is provided at the lower end of the housing 100. The limiting component 200 includes two sliding grooves 201 formed at the lower end of the housing 100. A connecting block 202 is slidably connected inside the sliding grooves 201. A limiting plate 203 is fixedly connected to the lower end of the connecting block 202. An installation groove 204 is formed on the inner wall of the limiting plate 203. A friction pad 205 is fixedly connected to the inner wall of the installation groove 204. A fixing component 300 is provided on the outer side of the limiting plate 203. The fixing component 300 includes a mounting block 301 fixedly connected to one side of the limiting plate 203. The mounting block 301 has a fixing groove 302 at its upper end near the housing 100. A return spring 303 is fixedly connected inside the fixing groove 302. A positioning block 304 is fixedly connected to the end of the return spring 303 away from the mounting block 301. A plurality of positioning grooves 305 are provided on the side of the housing 100 near the positioning block 304. A telescopic column 306 is fixedly connected to the inner wall of the fixing groove 302. The telescopic column 306 is located inside the return spring 303.

[0023] Specifically, first, press the positioning block 304 so that its wedge-shaped end completely exits the positioning groove 305 of the housing 100. At this time, the connecting block 202 is unlocked, and the operator can move the connecting block 202 along the guide trajectory of the sliding groove 201. Through the rigid connection structure between the connecting block 202 and the limiting plate 203, the limiting plate 203, which is equipped with the friction pad 205, moves towards the side wall of the fuel tank 800. When the friction pad 205 forms surface contact with the outer surface of the fuel tank 800 and generates appropriate clamping force, the force on the positioning block 304 is released. The return spring 303 pushes the positioning block 304 to move radially along the guide post, so that it re-locks into the positioning groove 305 of the corresponding thickness on the housing 100, forming a three-point positioning mechanical self-locking structure. This mechanism achieves universal fixing of fuel tanks 800 of different specifications through an adjustable limiting device, effectively eliminating the assembly gap between the fuel tank 800 and the vehicle frame mounting space, and preventing lateral movement caused by vibration during vehicle operation. During long-term use, it can maintain a stable clamping force, avoiding problems such as decreased sealing performance of fuel pipe joints and loosening of threaded connections caused by continuous shaking, which could lead to fuel leakage.

[0024] Reference Figure 1 and Figure 4 The upper end of the housing 100 is provided with a mounting hole 400, and a connecting pipe 500 is threaded inside the mounting hole 400. A plug 600 is slidably connected to the upper end of the connecting pipe 500, and a fixing pipe 700 is threaded to the lower end of the connecting pipe 500. An oil tank 800 is fixedly connected to the lower end of the fixing pipe 700. The upper end of the housing 100 is provided with multiple fixing holes 900, and an oil outlet pipe 110 is fixedly connected to the lower end of the oil tank 800.

[0025] Specifically, first, connect the fixing pipe 700 on the side of the fuel tank 800 to the matching connecting pipe 500 using internal and external threads. Next, connect the fuel outlet pipe 110 at the bottom of the fuel tank to the motorcycle's existing fuel line, ensuring the sealing ring is properly installed. After completing the pipe connection, smoothly place the entire fuel tank 800 body into the pre-reserved installation space on the frame and adjust it to the optimal position. Then, remove the special plug 600 and insert it vertically into the pre-drilled hole at the top of the connecting pipe 500 until it is fully secured. Finally, remove the matching bolts and pass them through the fixing holes 900 around the fuel tank 800. Use a torque wrench to secure the entire connection structure firmly to the motorcycle frame using the standard torque value.

[0026] Working principle: Pressing the positioning block 304 causes the wedge-shaped end of the positioning block 304 to completely exit the positioning groove 305 of the housing 100; at this time, the connecting block 202 is unlocked, and the operator can move the connecting block 202 along the guide trajectory of the sliding groove 201. Through the rigid connection structure between the connecting block 202 and the limiting plate 203, the limiting plate 203 equipped with the friction pad 205 is driven to move towards the side wall of the oil tank 800; when the friction pad 205 forms surface contact with the outer surface of the oil tank 800 and generates appropriate clamping force, the force on the positioning block 304 is released, and the reset spring 303 pushes the positioning block 304 to move radially along the guide post, so that it is re-locked into the positioning groove 305 of the corresponding thickness on the housing 100, forming a three-point positioning mechanical self-locking structure.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
