Description

Technical Field

[0001] This utility model relates to the field of fuel tank fixing technology, and in particular to a tractor fuel tank with a fixing structure. Background Technology

[0002] Tractors typically experience significant vibrations upon startup, which can cause the fuel tank to vibrate, potentially leading to displacement or rupture. Current technology generally uses straps to secure the fuel tank. However, these straps are prone to detachment under vibration. In harsh conditions, the fuel tank's movement can cause the straps to shift, loosen, and fall off. Furthermore, a poor fit between the straps and the fuel tank results in insufficient clamping force, failing to secure the tank. Additionally, the use of metal straps can lead to cutting into plastic fuel tanks when used for securing them. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0032] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0033] For ease of description below, an XYZ coordinate system is established, with the length of the fuel tank defined as the X-axis, the width as the Y-axis, and the height as the Z-axis. It is understood that the coordinate system of the fuel tank can be flexibly set according to actual needs; this application only provides an example and should not be considered a specific limitation thereof.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a structural schematic diagram of a tractor fuel tank with a fixed structure provided in an embodiment of this application. Figure 2 for Figure 1 Explosion diagram, Figure 3 This is a structural schematic diagram of the first angle of the fixed structure provided in an embodiment of this application. Figure 4 This is a structural schematic diagram of the second angle of the fixed structure provided in an embodiment of this application. Figure 5 This is a structural schematic diagram of the fixing structure provided in the embodiment of this application from a third angle. The tractor fuel tank with the fixing structure includes a fuel tank 100 and a fixing structure. The fuel tank 100 has a fixing part 101, which can be a part of the outer peripheral wall of the fuel tank 100. The fixing structure includes a clamping part 1, a fixing seat 2, and a connecting member 3.

[0035] The clamping part 1 is clamped onto the fixing part 101. The clamping part 1 has a limiting member 11 on one side in the X-axis direction and an adjusting member 12 on the other side. The clamping part 1 wraps around the fixing part 101, converting local impact into surface load and avoiding stress concentration that could cause the fuel tank 100 to crack.

[0036] The fixed base 2 is fixedly connected to the tractor. The fixed base 2 has a limiting channel 21 at one end in the X-axis direction. The head 111 of the limiting member 11 is locked onto the fixed base 2 through the limiting channel 21. The other end of the fixed base 2 has a first through hole 22.

[0037] The connector 3 is connected to the adjusting member 12 through the first through hole 22. The cooperation between the connector 3 and the adjusting member 12 controls the locking and unlocking of the limiting member 11 and the fixed seat 2. The limiting member 11 is locked through the limiting channel 21. The connector 3 is fastened on one side, which reduces the installation time.

[0038] A receiving space 4 is defined between the fixing seat 2 and the clamping part 1. The outline of the receiving space 4 is consistent with the outline of the fixing part 101, and the fixing part 101 is engaged in the receiving space 4.

[0039] In this way, by setting a fixing structure on the fuel tank 100, the fuel tank 100 is constrained in the X, Y and Z axes, eliminating the risk of displacement caused by tractor bumps and improving the reliability of positioning; it also solves the problems of insufficient fixing reliability and low installation efficiency of the fuel tank 100 under harsh working conditions.

[0040] In some embodiments of this application, the clamping part 1 may include a clamp 13 and a flexible belt 14 connected to the inner peripheral wall of the clamp 13. The flexible belt 14 wraps around the fixing part 101, and by setting the flexible belt 14, it serves to isolate the clamp 13 from direct contact with the fixing part 101, preventing the two sides of the clamp in the Y-axis direction from scraping against the fuel tank 100. Both sides of the flexible belt 14 are provided with flange structures 141, and the clamp 13 is installed between the two flange structures 141. The flange structures 141 form guide grooves, allowing the clamp 13 to be precisely positioned, preventing the clamp 13 from tilting or shifting due to tractor vibration, and improving assembly reliability. The dimension of the flexible belt 14 in the X-axis direction is greater than or equal to the dimension of the clamp 13 in the X-axis direction; that is, the length of the flexible belt 14 is greater than or equal to the length of the clamp 13, preventing the two ends of the clamp 13 in the X-axis direction from scraping against the fuel tank 100.

[0041] In some examples, the clamp 13 can be a metal component. For instance, the clamp 13 can be made of steel, iron, aluminum, or copper. Both ends of the clamp 13 have chamfered edges. These chamfered edges prevent the clamp edges from cutting the flexible band 14, thus protecting the fuel tank 100 and preventing scratches to operators during installation. The flexible band 14 can be made of rubber or silicone. Rubber or silicone components provide cushioning and shock absorption. On one hand, the flexible band 14 absorbs the vibrational potential energy of the fuel tank 100; on the other hand, the flexible band 14 makes soft contact with the fuel tank 100, thus protecting the fuel tank 100.

[0042] In some examples, the limiting member 11 can be a flat stud, which is welded to the clamp 13, and the head of the flat stud abuts against the lower surface of the fixing seat 2 through the limiting channel 21. In this way, using a flat stud increases the welding area between the flat stud and the clamp 13, thereby improving the connection strength between the flat stud and the clamp 13.

[0043] In some embodiments of this application, the limiting channel 21 can be a C-shaped channel, within which the flat stud is movable. The C-shaped channel includes an insertion section 211 and a limiting section 212 communicating with the insertion section 211. The channel width of the insertion section 211 is greater than or equal to the head diameter of the flat stud. The channel width of the limiting section 212 is less than the head diameter of the flat stud. Specifically, during use, the head of the flat stud passes through the insertion section 211, and the flat stud is manually moved along the limiting section 212, causing the flat stud to move to the end of the C-shaped channel away from the insertion section 211. In this way, the head of the flat stud abuts against the lower surface of the fixing seat 2, forming a vertical mechanical limit to resist the upward jumping force of the fuel tank 100. The width of the limiting section 212 of the C-shaped channel is smaller than the head diameter of the flat stud. During vibration, the head of the flat stud automatically locks into the limiting section 212. The loosening force needs to be manually released, which improves the reliability of the engagement between the flat stud and the C-shaped channel.

[0044] In some examples, the limiting channel 21 can also be a semi-circular channel, a U-shaped channel, a spiral channel, or other irregularly shaped channels.

[0045] In some embodiments, the adjusting member can be an extended nut, and the connecting member 3 can be a bolt adapted to the extended nut. The connection between the fixing seat 2 and the hoop 13 is tightened or loosened by the threaded engagement of the bolt and the extended nut. The engagement of the bolt and the extended nut can precisely control the preload and provide linear clamping force, thereby causing the hoop 13 to compress the flexible belt 14 and ensuring the stability of the connection between the fixing structure and the fuel tank 100.

[0046] In some embodiments, at least a portion of the sidewall of the fuel tank 100 is inclined; a wedge block 5 is provided on the lower surface of the fixing seat 2, and a second through hole 51 is provided on the wedge block 5. A bolt passes through the second through hole 51 and the first through hole 22 and is inclinedly connected to the extended nut. The wedge block 5 is used to compensate for the inclined surface of the sidewall of the fuel tank 100. The inclined connection avoids the main vibration direction (Z-axis) of the tractor, reducing the vibration transmission of the threaded pair. On the other hand, it increases the connection area and ensures the connection strength and stability between the clamp part 1 and the fixing seat 2.

[0047] In some examples, both the second through hole 51 and the first through hole 22 can be elongated holes, within which the bolt moves along the Y-axis. The elongated holes are used to release lateral stress caused by vibration.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
