Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a portable integrated repair tool. Background Technology

[0002] During the operation of medium- and high-speed diesel engines, inspections and maintenance should be carried out according to the specified levels in the maintenance manual. Some components of the diesel engine are specifically designed for this model and require the use of special tools. Meanwhile, the installation and connection between components are usually standard parts, requiring the use of general-purpose tools. Operators must bring all necessary special and general-purpose tools to complete the maintenance operation when repairing designated components. In particular, the repair interval for the centrifugal filter of medium- and high-speed diesel engines is 500 hours or 1 month, with a high frequency of disassembly and inspection to ensure the filter operates normally, thereby ensuring the good condition of the diesel engine's lubrication system.

[0003] However, during routine maintenance and disassembly of centrifugal filters, it was found that a large number of tools were involved in the disassembly and assembly, and the standard round nuts securing the rotor body presented difficulties in removal and assembly. Upon inspection, it was discovered that the centrifugal filter rotor body fixing bolts are designed as four-slot round nuts. In special circumstances where not all the necessary tools are available, the usual method on board is to use a hammer and a flathead screwdriver to knock them off. Since the maintenance interval is 500 hours or once a month, the high frequency of disassembly and assembly easily leads to damage to all four slots of the four-slot round nuts, causing the nuts to fail and resulting in difficulties in disassembly and assembly. Furthermore, when performing maintenance work in the confined space of the ship's cabin, the existing tools are often not designed to be flexible enough to adapt to the limited working environment. This makes it difficult to change the shape when using special clips to remove the nuts, increasing the difficulty and time consumption of maintenance work.

[0004] Therefore, it is necessary to provide a new portable integrated repair tool to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a portable integrated repair tool.

[0006] The portable integrated repair tool provided by this invention includes: a wrench body, a movable clamping block, a rectangular locking block, a plug rod, and a rotating cylinder. The wrench body consists of a fixed block in the middle and movable plates at both ends. The fixed block has a special slot in the middle for a four-groove round nut. The movable plates have a universal slot inside. One end of the movable plate has symmetrically arranged movable clamping blocks with adjustable spacing. The opposite ends of the movable plates are each equipped with a rectangular locking block for fixing the position of the movable plate and the fixed block. The universal slot has a plug rod inside. The plug rod is fitted with a rotating cylinder for gripping and rotating.

[0007] Preferably, one end of the two movable plates near the movable clamping block is provided with a first mounting groove. A bidirectional screw is rotatably connected to the inner wall of the first mounting groove. A roller is fixedly connected to the middle of the bidirectional screw, and sliders are symmetrically threaded to the outer walls of both ends of the screw. The sliders are fixedly connected to the corresponding movable clamping blocks, and the movable clamping blocks are slidably connected to the inner wall of the first mounting groove.

[0008] Preferably, each of the two movable plates has a placement groove inside its facing end, and the rectangular blocks are slidably connected to the inner wall of the corresponding placement groove. The inner wall of each placement groove is symmetrically fixedly connected to two springs, and the other end of each spring is fixedly connected to a spherical block. Both sides of the rectangular blocks have spherical slots corresponding to the spherical blocks. At least one set of the spherical blocks engages with the spherical slots. Both ends of the fixed block have grooves corresponding to the rectangular blocks inside, and in the initial state, the rectangular blocks are placed inside the corresponding grooves.

[0009] Preferably, each of the rectangular blocks has a sliding plate fixedly connected to its top. Each of the two movable plates has a groove at its top facing one end. The sliding plates are placed inside the corresponding grooves, and their bottom ends pass through the grooves and are fixedly connected to the rectangular blocks.

[0010] Preferably, each of the two movable plates is symmetrically fixedly connected to a limiting block at one end of its opposite side. The limiting block is used to restrict the movable plate from rotating 90 degrees around the point where it is connected to the fixed block.

[0011] Preferably, the interior of the movable plate is symmetrically provided with second mounting slots near the universal slot. A second spring is fixedly connected to the inner wall of the second mounting slot. A trapezoidal block is fixedly connected to one end of each second spring, and an L-shaped rod is fixedly connected to the side wall of each trapezoidal block. The L-shaped rod is slidably connected to the inner wall of the second mounting slot, and a button is fixedly connected to the other end of each L-shaped rod.

[0012] Preferably, the outer wall of the insertion rod is symmetrically provided with two sets of trapezoidal grooves corresponding to the trapezoidal blocks. The two sets of trapezoidal grooves are distributed vertically, and the distance between the two sets of trapezoidal grooves is equal to the distance between the trapezoidal blocks inside the two movable plates after rotating 90 degrees.

[0013] Preferably, a support rod is hinged to the top of the insertion rod. The support rod is placed inside the rotating cylinder and slidably connected to its inner wall. Two annular grooves are opened in the middle of the outer wall of the support rod, and straight grooves are radially symmetrically opened on its outer wall. Two sets of protruding rods are symmetrically fixedly connected to the inner wall of the rotating cylinder. In the initial state, a set of protruding rods near the top of the rotating cylinder is placed inside an annular groove near the top of the outer wall of the support rod and slidably connected to its inner wall.

[0014] Preferably, a rotating block is rotatably connected to one end of the insertion rod near the support rod, and the rotating block is used to fix the position of the support rod after rotation.

[0015] Compared with related technologies, the portable integrated repair tool provided by this invention has the following advantages:

[0016] I. Simplify tool carrying and reduce operational complexity

[0017] By integrating a dedicated slot for four-groove round nuts, a universal slot for removing general nuts, and a movable clamp into the wrench body, operators can handle a variety of repair scenarios with just this one tool. When removing general nuts, by removing the insert, using the universal slot, or adjusting the movable clamp, as well as adjusting the wrench body shape when removing four-groove round nuts, there is no need to frequently change different tools, which significantly simplifies the repair process, reduces operational complexity, saves tool preparation time, and improves repair efficiency.

[0018] II. Improving the efficiency and reliability of nut disassembly

[0019] This tool's dedicated slot design precisely fits the shape of the nut, avoiding the damage caused by hammering traditional tools that are not equipped with a nut. This protects the nut's structure, extends its service life, and reduces the difficulty and cost of repairs due to nut damage. During disassembly, the combination of components such as the rotating drum and insert rod provides a stable and effective force application method, making disassembly operations easier and more efficient, significantly improving nut disassembly efficiency compared to traditional methods.

[0020] For different types of universal nuts, the movable clamps can flexibly adjust the spacing to quickly adapt to various nut sizes, thus achieving efficient disassembly and meeting the needs of handling different nuts in maintenance work;

[0021] III. Flexible adaptation to confined work spaces

[0022] The special structural design of the movable plate, insertion rod, and rotating drum allows for adjustment of the shape according to the needs of the work space; it further optimizes the ease of operation in confined spaces, effectively solves the problem of inconvenience of traditional tools in confined spaces, reduces the difficulty of maintenance work, and improves the feasibility and efficiency of operation in complex spatial environments.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] Example 1

[0036] Please see Figures 1 to 9A portable integrated repair tool includes: a wrench body 1, a movable clamping block 6, a rectangular locking block 7, a plug rod 8, and a rotating cylinder 9. The wrench body 1 consists of a fixed block 2 in the middle and movable plates 3 at both ends. The fixed block 2 has a special slot 4 in the middle for a four-groove round nut. The movable plates 3 have a universal slot 5 inside. One end of the movable plate 3 has symmetrically arranged movable clamping blocks 6 with adjustable spacing. The opposite ends of the movable plates 3 are each equipped with a rectangular locking block 7 for fixing the position of the movable plate 3 and the fixed block 2. The universal slot 5 has a plug rod 8 inside. The plug rod 8 is fitted with a rotating cylinder 9 for gripping and rotating. The two movable plates 3 are positioned such that the one closest to the other... One end of the movable clamping block 6 is provided with a first mounting groove. The inner wall of the first mounting groove is rotatably connected to a bidirectional screw 10. The middle of the bidirectional screw 10 is fixedly connected to a roller 11. The outer wall of the roller 11 is provided with anti-slip points to increase friction when rotating. The outer walls of its two ends are symmetrically threaded with sliders 12. The sliders 12 are fixedly connected to the corresponding movable clamping block 6, and the movable clamping block 6 is slidably connected to the inner wall of the first mounting groove. When it is necessary to disassemble the universal nut, it can be decided whether to pull out the insertion rod 8 or adjust its position according to the actual situation. When there is enough space and the universal nut can be rotated one turn by turning it horizontally, the insertion rod 8 can be quickly disassembled by holding the rotating cylinder 9 outside the insertion rod 8 and rotating it. If the space is limited, the insertion rod 8 can be pulled out.

[0037] Example 2

[0038] Please see Figures 3 to 9Each of the two movable plates 3 has a placement groove inside its facing end. Rectangular blocks 7 are slidably connected to the inner wall of the corresponding placement groove. Two springs 13 are symmetrically fixed to the inner wall of each placement groove. A spherical block 14 is fixedly connected to the other end of each spring 13. Spherical slots 15 corresponding to the spherical blocks 14 are formed on both sides of each rectangular block 7. At least one set of spherical blocks 14 engages with a spherical slot 15. The fixed block 2 has grooves corresponding to the rectangular blocks 7 inside its two ends. Initially, the rectangular blocks 7 are placed inside the corresponding grooves, engaging with the grooves at the ends of the fixed block 2, thus connecting the fixed block 2 and the movable plate 3. The connection is a single, robust unit. Each rectangular locking block 7 has a sliding plate 16 fixedly connected to its top. The top of the sliding plate 16 has anti-slip textures to increase friction during sliding. Each of the two opposing ends of the movable plates 3 has a groove at its top, and the sliding plates 16 are placed inside the corresponding grooves, with their bottom ends passing through the grooves and fixedly connected to the rectangular locking block 7. Each of the opposing ends of the two movable plates 3 has a symmetrically fixed limiting block 17, which restricts the movable plate 3 from rotating 90 degrees around the connection point with the fixed block 2. Each movable plate 3 has a second mounting groove symmetrically located near the universal locking slot 5 inside, and a spring is fixedly connected to the inner wall of the second mounting groove. 18. One end of each spring 18 is fixedly connected to a trapezoidal block 19, which is slidably connected to the inner wall of the second mounting groove. Each trapezoidal block 19 has an L-shaped rod 20 fixedly connected to its side wall, which is also slidably connected to the inner wall of the second mounting groove. The other end of each L-shaped rod 20 is fixedly connected to a button 21. The outer wall of the insert rod 8 has two sets of trapezoidal grooves 22 symmetrically arranged, corresponding to the trapezoidal blocks 19. These two sets of trapezoidal grooves 22 are arranged vertically, and the distance between the two sets of trapezoidal grooves 22 is equal to the distance between the two trapezoidal blocks 19 inside the two movable plates 3 after rotating 90 degrees. A support rod 23 is hinged to the top of the insert rod 8, and the support rod 23 is placed inside the rotating cylinder 9. It is slidably connected to its inner wall. Two annular grooves 24 are opened in the middle of the outer wall of the support rod 23, and straight grooves 25 are radially symmetrically opened on its outer wall. The straight grooves 25 at both ends of the support rod 23 are connected to the corresponding annular grooves 24. Two sets of protruding rods 26 are symmetrically fixedly connected to the inner wall of the rotating cylinder 9. The end of the protruding rod 26 is designed as a ball head and matches the inner wall of the annular groove 24. In the initial state, the set of protruding rods 26 near the top of the rotating cylinder 9 is placed in the annular groove 24 near the top of the outer wall of the support rod 23 and is slidably connected to its inner wall. The end of the insertion rod 8 near the support rod 23 is rotatably connected to a rotating block 27. The rotating block 27 is used to fix the position of the support rod 23 after rotation.

[0039] The working principle of the portable integrated repair tool provided by this invention is as follows:

[0040] 1. Disassembling the universal nut

[0041] When it is necessary to remove the universal nut, the first step is to remove the insert rod 8 inserted into the universal slot 5. Specifically, the user needs to press the buttons 21 on both sides of the wrench body 1. The buttons 21 are connected to the L-shaped rod 20. Pressing the buttons 21 will cause the L-shaped rod 20 to move relative to each other under the guidance of the inner wall of the second mounting groove. The L-shaped rod 20 drives the corresponding trapezoidal block 19 to move synchronously. During this process, the trapezoidal block 19 compresses the second spring 18, causing the trapezoidal block 19 to disengage from the trapezoidal groove 22 opened on the outer wall of the insert rod 8. At this time, the insert rod 8 loses the locking restriction of the trapezoidal block 19. Then, the user can easily pull the insert rod 8 out of the universal slot 5. After releasing the buttons 21, the compressed second spring 18 releases its elasticity, pushing the trapezoidal block 19 and the L-shaped rod 20 to reset and return to the initial state.

[0042] Subsequently, the universal slot 5 inside the movable plate 3 at one end of the wrench body 1 can be used to disassemble the universal nut; if a different type of universal nut is encountered, the movable clamping block 6 at the other end of the wrench body 1 can play a role; rotate the roller 11, and the bidirectional screw 10 fixedly connected at the axis of the roller 11 will rotate accordingly; since the slider 12 is threadedly connected to the outer walls of both ends of the bidirectional screw 10, and the slider 12 is fixed to the corresponding movable clamping block 6, while the movable clamping block 6 is slidably connected to the inner wall of the first mounting groove, under the restriction of the inner wall of the first mounting groove, the movable clamping block 6 moves axially along the bidirectional screw 10 along the slider 12; by observing the size of the nut, the roller 11 is continuously rotated to adjust the two movable clamping blocks 6 to the appropriate position so that the movable clamping blocks 6 can firmly clamp the nut, thereby performing the disassembly operation;

[0043] II. Disassembling the four-slot round nut

[0044] When it is necessary to disassemble the four-slot round nut, the shape of the wrench body 1 must be adjusted first; press and push the sliding plate 16 on the top of the movable plate 3. The bottom end of the sliding plate 16 is fixedly connected to the rectangular block 7, so the movement of the sliding plate 16 will cause the rectangular block 7 to slide in the placement groove; during the movement of the rectangular block 7, the inner wall of the spherical groove 15 opened on both sides of it squeezes the spherical block 14, forcing the spherical block 14 to compress the spring 13 and disengage from the spherical groove 15; continue to push the sliding plate 16 until the spherical groove 15 on the side wall of the rectangular block 7 is fully engaged with the two spherical blocks 14. At this time, the other end of the rectangular block 7 is completely disengaged from the groove inside the fixed block 2, and the movable plate 3 gains rotational freedom;

[0045] Next, rotate the movable plate 3. Since the ends of the movable plate 3 that are close to each other are fixedly connected to the limiting block 17, the limiting block 17 cooperates with the fixed block 2, restricting the movable plate 3 to rotate only 90 degrees around the point of rotational connection with the fixed block 2, so that the movable plate 3 and the fixed block 2 are in a perpendicular state. At this time, hold the end of the insertion rod 8 with one hand and hold the rotating cylinder 9 with the other hand to rotate and pull it outward. A set of protruding rods 26 near the top of the rotating cylinder 9 rotates in the annular groove 24 inside the support rod 23. When it rotates to the position of the straight groove 25, the rotating cylinder 9 can be pulled outward, and the insertion rod 8 gradually appears. Continue to pull the rotating cylinder 9, and a set of protruding rods 26 near the bottom of its interior contacts the support rod 23. Rotate the rotating cylinder 9 again and pull it outward. When the protruding rod 26 rotates to correspond to the straight groove 25, pull it into the straight groove 25 near the bottom of the support rod 23. At this time, the relative position of the rotating cylinder 9 and the insertion rod 8 is adjusted.

[0046] Press the button 21 on the side wall of any one of the movable plates 3 again. The corresponding trapezoidal block 19 will retract into the second mounting slot under the action of the L-shaped rod 20. Insert the end of the insert rod 8 away from the support rod 23 into the universal slot 5 and release the button 21. At this time, the spring 18 corresponding to the slot is in a compressed state. Continue to insert the insert rod 8. The end of the insert rod 8 will press the trapezoidal block 19 in the other universal slot 5, causing it to compress the spring 18. When the trapezoidal groove 22 on the outer wall of the insert rod 8 corresponds to the trapezoidal block 19, the spring 18 will release its elasticity and push the trapezoidal block 19 to engage with the corresponding trapezoidal groove 22, thus completing the fixation of the insert rod 8 between the universal slots 5 in the two movable plates 3.

[0047] Finally, rotate the drum 9, which drives the support rod 23 to rotate. When the drum 9 rotates to be perpendicular to the insertion rod 8, rotate the rotating block 27 connected to the end of the insertion rod 8. The rotating block 27, through its cooperation with the insertion rod 8 and the support rod 23, fixes the position of the support rod 23 and prevents it from rotating in the opposite direction. At this time, the user can use the special slot 4 inside the fixing block 2 to remove the four-groove round nut. Simply put the special slot 4 on the outer wall of the four-groove round nut, and then hold the drum 9 and rotate it to remove it. Compared with the traditional wrench, this method can effectively reduce the space occupied by the wrench, which is especially suitable for working in a small cabin space, reducing maintenance difficulty and improving work efficiency.
