DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a fuel pipe connecting device for a fuel gun includes a fuel pipe body 1, a fixed block 3 and a fuel gun handle 4. A fixed sleeve 6 is fixedly connected to the outer side of the fuel pipe body 1, and the fixed block 3 is fixedly connected to the top of the fixed sleeve 6. A slide groove 12 is provided inside the fixed block 3, and a limiting mechanism is provided inside the slide groove 12. The fuel gun handle 4 is provided on one side of the fuel pipe body 1, and a first connecting sleeve 5 is fixedly connected to one side of the fuel gun handle 4, and a second connecting sleeve 23 is slidably connected to the inner wall of the first connecting sleeve 5. One end of the fuel pipe body 1 is fixedly connected to one side of the second connecting sleeve 23, and a sealing groove 11 is provided inside the second connecting sleeve 23, and a sealing ring 10 is provided inside the sealing groove 11. An L-shaped plate 7 is fixedly connected to one side of the fixed block 3, and a locking mechanism is provided on one side of the L-shaped plate 7.

[0022] First, when installing the oil gun handle 4 and the oil pipe body 1, the first connecting sleeve 5 is connected to the second connecting sleeve 23, and then the sealing between the oil gun and the oil pipe body 1 is increased by the sealing ring 10 inside the sealing groove 11. At this time, the oil gun handle 4 and the oil pipe body 1 can be automatically fixed by the limiting mechanism, thereby saving installation time and increasing the convenience of installation. Then, the locking mechanism is rotated to move the locking mechanism to fix the position of the limiting mechanism. This can avoid the problem of the oil gun handle 4 and the oil pipe body 1 being separated due to accidental contact, thereby increasing the stability of the device.

[0023] like Figure 1-Figure 4As shown, the limiting mechanism includes a slider 13, which is slidably connected to the inside of the slide groove 12, and a spring 15 is fixedly connected between the top of the slider 13 and the inner wall of the slide groove 12. The limiting mechanism also includes a clamping block 14, which is slidably connected to the inside of the fixed block 3, and the top of the clamping block 14 is fixedly connected to the bottom of the slider 13. The top of the first connecting sleeve 5 is fixedly connected to the displacement block 2, and a groove 9 is provided on one side of the fixed block 3. The outer side of the displacement block 2 is slidably connected to the inner wall of the groove 9. A clamping groove 8 is provided on the top of the displacement block 2, and one end of the clamping block 14 extends to the inside of the groove 8. A limiting groove 16 is provided on one side of the fixed block 3, and a lever 17 is slidably connected to the inside of the limiting groove 16. One end of the lever 17 is fixedly connected to one side of the slider 13, and one end of the clamping block 14 is provided with an inclined surface.

[0024] During installation, one end of the displacement block 2 is moved into the interior of the receiving groove 9, and then one side of the displacement block 2 contacts the inclined surface of the block 14, thereby driving the slider 13 to move inside the slide groove 12 and compressing the spring 15. Then, when the slot 8 moves to the bottom of the block 14, the block 14 is driven into the slot 8 by the reaction force of the spring 15, thereby automatically completing the fixing operation. Then, when releasing the fixation, the lever 17 is driven to slide inside the limit groove 16 while driving the slider 13 to move, and then the block 14 is driven to detach from the slot 8, so that the disassembly operation can be conveniently performed.

[0025] like Figure 1-Figure 4 As shown, the locking mechanism includes a threaded rod 20, which is rotatably connected to one side of the fixed block 3, and the outer side of the threaded rod 20 is threadedly connected to a displacement plate 18, and one side of the displacement plate 18 is fixedly connected to a baffle 19. The locking mechanism also includes a displacement groove 21, which is opened on one side of the L-shaped plate 7, and a displacement rod 22 is slidably connected inside the displacement groove 21, and one end of the displacement rod 22 is fixedly connected to one side of the displacement plate 18.

[0026] After the installation is completed, the displacement plate 18 is driven to move by rotating the threaded rod 20 and the displacement rod 22 is driven to slide inside the displacement groove 21, thereby limiting the movement of the displacement plate 18. Then the displacement plate 18 moves to drive the baffle 19 to approach one side of the lever 17, thereby blocking the top of the lever 17, avoiding the problem of the lever 17 moving due to misoperation when using the oil gun handle 4, thereby increasing the safety of the device.

[0027] The utility model provides an oil pipe connecting device for a refueling gun, and the specific working principle is as follows: first, when the oil gun grip 4 and the oil pipe body 1 are installed, the first connecting sleeve 5 is connected to the second connecting sleeve 23, and then the sealing between the oil gun and the oil pipe body 1 is increased by the sealing ring 10 inside the sealing groove 11. Then, when installing, one end of the displacement block 2 is moved into the inside of the receiving groove 9, and then one side of the displacement block 2 is in contact with the inclined surface of the clamping block 14, thereby driving the slider 13 to move inside the slide groove 12 and compressing the spring 15 at the same time. Then, when the clamping groove 8 moves to the bottom of the clamping block 14, the clamping block 14 is driven to enter the clamping groove 8 by the reaction force of the spring 15. The interior is automatically fixed, and then when releasing the fixation, the lever 17 is pushed to slide in the limit groove 16 and the slider 13 is moved, and then the block 14 is disengaged from the inside of the slot 8, so that the disassembly operation can be conveniently performed. Then, after the installation is completed, the displacement plate 18 is driven to move by rotating the threaded rod 20 and the displacement rod 22 is driven to slide in the displacement groove 21, thereby limiting the movement of the displacement plate 18, and then the displacement plate 18 moves to drive the baffle 19 to approach one side of the lever 17, thereby blocking the top of the lever 17, avoiding the problem of the lever 17 moving due to misoperation when using the oil gun grip 4, thereby increasing the safety of the device.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
