Description
Technical Field
[0001] This utility model relates to the technical field of pipe disassembly tools, and more specifically, to a tool for disassembling and repairing oil pipes. Background Technology
[0002] With the development of automotive technology, the complexity and precision of fuel systems are constantly increasing. The connection between fuel pumps and fuel lines is also becoming more efficient and reliable. Due to their ease of installation and disassembly, internal snap-fit couplings (quick couplings) are widely used in modern automotive fuel systems. Traditional disassembly methods may damage the couplings or fuel lines, and special tools can reduce this risk.
[0003] In actual use, when disassembling different models of internal clamp oil pipes, it is not possible to keep the disassembly tool in close contact with the outer wall of the internal clamp oil pipe in time, and a certain amount of operating space is required for inserting and removing the internal clamp oil pipe, which affects the efficiency of inserting the oil pipe. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a repair and maintenance oil pipe disassembly tool to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The oil pipe repair and disassembly tool includes a base frame. A handle is fixedly connected to the bottom of the base frame, and a fixing block is fixedly connected to one side of the base frame. A threaded rod is rotatably connected to the inside of the base frame, and a handle is fixedly connected to one end of the threaded rod. A sliding block is threadedly connected to the outside of the handle, and an oil pipe clamping mechanism is fixedly connected to the top of the sliding block. The oil pipe clamping mechanism includes a bracket, the bottom of which is fixedly connected to the top of the sliding block. The bracket has a U-shaped cross-section, and multiple guide blocks are slidably connected to the inside of the bracket. Two push rods are slidably connected to the outside of the bracket, and two sliding grooves are formed on the outside of the push rods. One side of the push rod is fixedly connected to... The device includes a push block, a push rod with multiple slots at its top, an arc-shaped clamp fixedly connected to one side of the push rod, multiple anti-slip pads fixedly connected to one side of the arc-shaped clamp, a clamping plate fixedly connected to the outer side of the arc-shaped clamp, two outer cylinders fixedly connected to the top of the bracket, a pull rod slidably connected to the inner side of the outer cylinder, a slider fixedly connected to the outer side of the pull rod, the outer side of the slider slidably connected to the inner side of the outer cylinder, a spring fixedly connected to the top of the slider, the top of the spring fixedly connected to the inner side of the outer cylinder, a clamping block fixedly connected to the bottom of the pull rod, the outer side of the clamping block inserting into the inner side of the slot; and a release mechanism provided on the top of the fixing block.
[0007] By adopting the above technical solution: using two push rods to drive two arc-shaped clamping plates, anti-slip pads and clamping plates to clamp the joints of different models of internal clamping oil pipes, and then by inserting the corresponding clamping blocks into the clamping slots, the oil pipes are promptly limited after clamping. At the same time, by using the rotation of the threaded rod, the sliding block can smoothly pull the internal clamping oil pipes, improving the convenience and stability of disassembling the internal clamping oil pipes.
[0008] As a further description of the above technical solution: the unlocking mechanism includes an arc rod one, the bottom of which is fixedly connected to the top of the fixed block, and an arc rod two hinged to the top of the arc rod one. An arc-shaped push plate is fixedly connected to one side of both the arc rod one and the arc rod two. A rotating block is hinged to one side of the arc rod two. Two levers are fixedly connected to the inner side of the rotating block. A spring two is fixedly connected to one end of each lever. An insert block is fixedly connected to one side of the spring two. The outer side of the insert block is slidably connected to the inner side of the rotating block. One side of the insert block is engaged with the inner side of the arc rod one.
[0009] By adopting the above technical solution: using arc rod one and arc rod two to wrap the fuel pump connector, the two arc-shaped pushers can be aligned with the locking block inside the inner locking connector, thereby assisting the inner locking oil pipe connector to quickly separate from the oil pipe.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] By setting up an oil pipe clamping mechanism, compared with the existing technology, the opposing movement of two push rods allows two arc-shaped clamping plates to clamp oil pipes of different diameters. The insertion of the clamping block and the clamping slot ensures stable clamping. Furthermore, the threaded drive of the threaded rod allows the oil pipe clamping mechanism to smoothly separate the oil pipe joint from the fuel pump interface. This effectively reduces the insertion and removal actions of maintenance personnel during oil pipe disassembly, making oil pipe disassembly more convenient and labor-saving.
[0012] By setting up a disengagement mechanism, compared with existing technologies, two arc-shaped pushers are used to quickly push the jamming block in the internally jammed oil pipe joint, which reduces the difficulty of disassembling the internally jammed oil pipe and improves the efficiency of oil pipe disassembly.

The guide block 8 and the bracket 7 are slidably connected to two push rods 9. Two grooves 10 are formed on the outer side of each push rod 9. A push block 11 is fixedly connected to one side of each push rod 9. Multiple slots 12 are formed on the top of each push rod 9. An arc-shaped clamping plate 13 is fixedly connected to one side of each push rod 9. Multiple anti-slip pads 14 are fixedly connected to one side of the arc-shaped clamping plate 13. A clamping plate 15 is fixedly connected to the outer side of the arc-shaped clamping plate 13. Two outer cylinders 16 are fixedly connected to the top of the bracket 7. A pull rod 17 is slidably connected to the inner side of each outer cylinder 16. A [missing information - likely a device or component] is fixedly connected to the outer side of each pull rod 17. The slider 18 is slidably connected to the outer side of the outer cylinder 16. A spring 19 is fixedly connected to the top of the slider 18, and the top of the spring 19 is fixedly connected to the inner side of the outer cylinder 16. A locking block 20 is fixedly connected to the bottom of the pull rod 17, and the outer side of the locking block 20 is inserted into the inner side of the locking groove 12. The top of the fixing block 3 is provided with a release mechanism, which pushes the two push blocks 11 to drive the push rod 9 to move in opposite directions inside the bracket 7, so that the anti-slip pad 14 and the locking plate 15 on one side of the two brackets 7 are clamped to the joint of the inner locking oil pipe. At the same time, spring 19 pushes slider 18 to drive pull rod 17 and locking block 20 to slide inside bracket 7, so that locking block 20 can be inserted into the slot 12 at the top of push rod 9, so that the two push rods 9 can be positioned in time after being pushed to the appropriate position. Then, turn handle 5 to drive threaded rod 4 to perform threaded transmission on sliding block 6, so that sliding block 6 drives two arc-shaped clamps 13 and locking plate 15 through bracket 7 to pull the joint of inner clamp oil pipe, so that inner clamp oil pipe is separated from fuel pump joint.
[0022] Reference Figure 2 , Figure 3 and Figure 6As shown, the unlocking mechanism includes an arc rod 21, the bottom of which is fixedly connected to the top of the fixed block 3. An arc rod 22 is hinged to the top of the arc rod 21. An arc-shaped push plate 23 is fixedly connected to one side of both the arc rod 21 and the arc rod 22. A rotating block 24 is hinged to one side of the arc rod 22. Two levers 25 are fixedly connected to the inner side of the rotating block 24. A spring 26 is fixedly connected to one end of each lever 25. An insert block 27 is fixedly connected to one side of the spring 26. The outer side of the insert block 27 is slidably connected to the inner side of the rotating block 24. One side of the insert block 27 is connected to the arc rod 22. The inner side of rod 21 is engaged. Rotate the second arc rod 22 so that the rotating block 24 on one side of the second arc rod 22 engages with one side of the first arc rod 21. Then, use the two springs 26 on the inner side of the rotating block 24 to push the insert block 27 to engage the inner side of the first arc rod 21. This allows the first arc rod 21 and the second arc rod 22 to wrap around the fuel pump interface. Then, align the two arc-shaped pushers 23 with the inner side of the inner clamping oil pipe connector and push the two arc-shaped pushers 23 against the clamping block on the inner side of the inner clamping oil pipe connector, thereby separating the inner clamping oil pipe from the fuel pump interface.
[0023] The working principle of this utility model is as follows: When disassembling the internal fuel line, the operator holds the handle 2 and brings the inner side of the arc rod 21 on the top of the fixing block 3 on one side of the base frame 1 into contact with the bottom of the fuel pump interface. Then, the arc rod 22 is pushed to rotate on the top of the arc rod 21, so that the rotating block 24 on one side of the arc rod 22 can engage with one side of the arc rod 21. The two springs 26 on the inner side of the rotating block 24 push the two insert blocks 27 to engage with the inner side of the arc rod 21, so that the arc rod 22 and the arc rod 21 can wrap around the fuel pump interface in a ring. Then, the inner clamping oil pipe is inserted into the inner side of the bracket 7, so that the arc-shaped clamping plate 13 and clamping plate 15 on one side of the two push rods 9 can align the joint of the inner clamping oil pipe. Then, push the two push blocks 11 to drive the push rods 9 and the slide groove 10 to clamp the outer wall of the oil pipe under the guidance of multiple guide blocks 8 inside the bracket 7. While the two arc-shaped clamping plates 13 clamp the outer wall of the oil pipe, the springs 19 inside the two outer cylinders 16 will push the slider 18 to drive the clamping block 20 to insert and fix the corresponding push rod 9 to the corresponding top of the clamping groove 12, so that the two push rods 9 can maintain relative stability and avoid loosening.
[0024] Then, the two arc-shaped push plates 23 on one side of the arc rod 1 21 and arc rod 22 can be inserted into the interface of the inner clamp oil pipe, so that the top of the two arc-shaped push plates 23 can push the retaining ring on the inside of the inner clamp oil pipe, thereby separating the inner clamp oil pipe from the fuel pump interface. Finally, turn the handle 5 to drive the threaded rod 4 to perform threaded transmission on the sliding block 6, so that the sliding block 6 can slide on the top of the base frame 1, thereby allowing the bracket 7 to separate the inner clamp oil pipe from the fuel pump interface through the two push rods 9 and the arc-shaped clamp 13, completing the oil pipe disassembly.
