Description

Technical Field

[0001] The utility model relates to the technical field of engine fuel tanks, in particular to an engine fuel tank which is easy to disassemble, assemble and maintain. Background Art

[0002] The fuel tank, i.e. the fuel storage device, has high requirements for corrosion resistance. It should be sealed when the gauge pressure is at least 0.03MPa at double working pressure. The generated overpressure must be reduced by itself through a hole or a safety valve. When driving on a curve, inclined road or impacted, the fuel should not flow out from the sealing cap or pressure balance device for filling. The fuel tank must be installed away from the engine to avoid ignition of the fuel in the event of a traffic accident.

[0003] For example, the patent publication number CN202320789751.0 is an engine fuel tank that is easy to disassemble and maintain. First, the staff can place the fuel tank body between the two positioning frames, and tighten the tops of the two positioning frames by twisting the blocks to position them. Then, the limit frame is set on the right side of the surface of the fuel tank body, and the second bolt is screwed into the inside of the mounting hole, so as to position the limit frame and the two positioning frames, so as to splice them into a protective frame to position and protect the fuel tank body. Then, the staff places the bottoms of the two positioning frames in the slots of the card plate, and screws the first bolt into the inside of the positioning hole. The utility model is used in coordination with the fuel tank body, the positioning frame, the positioning hole, the card plate, the limit frame, the mounting hole, the oil filling pipe, the twist cover, the jack, the filter housing and the first sealing housing;

[0004] Since the above-mentioned engine fuel tank is clamped and constrained by a positioning frame and a limit frame sleeve, the subsequent disassembly and assembly process needs to be disassembled as a whole or in half, which may easily cause the engine fuel tank installation to loosen and move, making it inconvenient to carry out stable engine fuel tank inspection and maintenance work, which has a certain adverse effect on actual use, and therefore needs to be improved.

[0023] Furthermore, a guide groove 12 is opened on the top of the staging platform 1, and a guide plate 13 is fixedly connected to the bottom of the fuel tank body 2. The surface of the guide plate 13 and the inner wall of the guide groove 12 are slidably connected. The guide groove 12 and the guide plate 13 can be used to adjust the position of the fuel tank body 2 on the staging platform 1, so as to adjust the fuel tank bodies 2 of different sizes and their installation positions.

[0024] Furthermore, a wear-resistant and anti-skid pad 14 is fixedly connected to the surface of the side clamping plate 5 , and the surface of the wear-resistant and anti-skid pad 14 abuts against the side of the fuel tank body 2 . Under the action of the wear-resistant and anti-skid pad 14 , the side clamping and anti-skid effect of the fuel tank body 2 is enhanced.

[0025] Furthermore, the bottom of the adjustable magnetic plate 8 is a protective cover 19, and a spring telescopic rod 20 is fixedly installed on the top of the protective cover 19, and one end of the spring telescopic rod 20 is fixedly connected to a magnetic abutment plate 21, and the top of the magnetic abutment plate 21 is fixedly connected to a pulling telescopic rod 22, and the top of the pulling telescopic rod 22 is fixedly connected to the top of the inner wall of the protective cover 19, and the auxiliary pressure plate 7 is fixedly installed with an adjustable magnetic plate 8, which can automatically elastically control the spring telescopic rod 20 to be telescopic and pressed on the fuel tank body 2, and the magnetic abutment plate 21 at the bottom end of the spring telescopic rod 20 can abut and be magnetically attracted to the top of the fuel tank body 2, thereby assisting the locking effect, and under the action of pulling the telescopic rod 22, the vertical anti-tilt lifting and lowering operation of the magnetic abutment plate 21 is guaranteed to ensure the positioning and anti-loosening effect of the fuel tank body 2 during the movement.

[0026] Example 2, please refer to Figures 1 to 5 The difference between this embodiment and the first embodiment is that the connection assembly includes an anti-skid card plate 15 and an anti-skid card groove 16, the anti-skid card plate 15 is fixedly connected to the top of the side clamping plate 5, the anti-skid card groove 16 is provided on the bottom of the upper clamping plate 6, and the inner wall of the anti-skid card groove 16 is clamped and adapted to the surface of the anti-skid card plate 15. The inside of the anti-skid card plate 15 and the inside of the anti-skid card groove 16 are both threadedly connected with a fixing screw 17 through an internal thread groove, the top of the upper clamping plate 6 is provided with a recessed hidden groove 18, and the fixing screw 17 is located inside the recessed hidden groove 18. By utilizing the clamping relationship between the anti-skid card plate 15 and the anti-skid card groove 16, the upper clamping plate 6 is quickly pressed down and positioned at the top of the fuel tank body 2, and then the fixing screw 17 is rotated to secondarily fix the upper clamping plate 6 and the side clamping plate 5. By setting the recessed hidden groove 18, the influence of external conditions on the fixing screw 17 is reduced.

[0027] Working principle: When the engine fuel tank which is easy to disassemble and maintain is in use, during the stable installation operation of the fuel tank body 2, the guide groove 12 and the guide plate 13 can be used to adjust the position of the fuel tank body 2 on the mounting platform 1, so as to adjust the fuel tank bodies 2 of different sizes and their installation positions. After the basic positioning of the fuel tank body 2 is completed, the reversing pin shaft seat 4 can be used to rotate and adjust the position of the side clamping plate 5. Under the action of the wear-resistant and anti-skid pad 14, the side clamping and anti-skid effect of the fuel tank body 2 is enhanced. After the four side clamping plates 5 are clamped in position, the anti-skid clamping plate 15 and the anti-skid clamping groove 16 can be used to quickly press down the upper pressure plate 6 and position it at the top of the fuel tank body 2, and then the fixing screw 17 is rotated to secondarily fix the upper pressure plate 6 and the side clamping plate 5. The setting of the concave hidden groove 18 reduces the influence of external conditions on the fixing screw 17. The front and rear sides of 6 are both provided with auxiliary pressure plates 7 to assist in pressing. Because the auxiliary pressure plate 7 is fixedly installed with an adjustable magnetic suction plate 8 inside, the spring telescopic rod 20 can be automatically elastically controlled to be telescopically pressed against the fuel tank body 2. The magnetic suction abutment plate 21 at the bottom end of the spring telescopic rod 20 can abut against the top of the fuel tank body 2, thereby assisting in the locking effect. Under the action of pulling the telescopic rod 22, the vertical anti-tilt lifting and lowering operation of the magnetic suction abutment plate 21 is guaranteed. In order to ensure the positioning and anti-loosening effect of the fuel tank body 2 during movement, the screw under the abutment baffle 10 can be rotated to enter the positioning thread groove 9. Under the elastic slow-pressure abutment of the elastic outer abutment ring 11, the fuel tank body 2 can be abutted against the rear end of the mounting platform 1, so that the upper pressure plate 6 can be quickly removed later. When the side clamping plate 5 is flattened, the fuel tank body 2 is relatively stable and anti-loose on the mounting platform 1, so as to carry out stable maintenance work of the anti-disassembly fuel tank body 2.
