Description

Technical Field

[0001] This utility model relates to the technical field of generator filter changer wrenches, and in particular to a special wrench for quick filter changers of generators used on tugboats. Background Technology

[0002] During long-term voyages and high-load operations, tugboats require generators to maintain continuous and stable operation to ensure the normal power supply to various electrical equipment on board. During generator operation, the oil filter plays a crucial role in filtering impurities, metal shavings, and deposits from the oil, effectively preventing contamination of the oil circulation system and thus ensuring the lubrication and lifespan of engine components. Because the filter element can become clogged with impurities after a period of use, affecting its filtration efficiency, the oil filter needs to be replaced regularly to maintain the generator's efficient operation and the equipment's safety and reliability.

[0003] In the existing technology, the structural design of wrenches is relatively simple, usually relying only on basic cylindrical or flat handles. They lack ergonomic grip design, which makes them easy to slip or cause hand fatigue during use. This makes it difficult to apply stable force to fasteners, thus limiting operating efficiency and safety, and making it difficult to meet the needs of long-term or high-intensity work. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special wrench for quick filter replacement of generators for tugboats. It aims to improve the existing technology where the wrench structure design is relatively simple, usually relying only on a basic cylindrical or flat handle, lacking an ergonomic grip design, which leads to problems such as slippage or hand fatigue during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A special wrench for quick filter replacement of generators for tugboats includes a handle, an anti-slip structure on the outside of the handle, a movable rod inserted into the left end of the handle, and an installation ring installed at the left end of the movable rod. A rotating ring is provided inside the installation ring, and a wrench frame is installed inside the rotating ring.

[0006] By adopting the above technical solutions, the wrench frame is installed inside the rotating ring, and the handle is held. The grip is enhanced by the anti-slip structure to ensure stability during use. Then, the wrench frame is placed on the outside of the part that needs to be adjusted, and the operation is performed by twisting the handle.

[0007] Preferably, the anti-slip structure includes an anti-slip sleeve, which is fitted onto the outside of the handle and is made of rubber. The outer surface of the anti-slip sleeve is uniformly provided with multiple sets of anti-slip grooves.

[0008] Preferably, the anti-slip structure includes an anti-slip sleeve, which is fitted onto the outside of the handle and is made of rubber. Multiple sets of anti-slip balls are evenly distributed on the outer surface of the anti-slip sleeve.

[0009] Preferably, an anti-slip rope is provided on the right side of the handle.

[0010] Preferably, the movable rod is movably inserted into the left end of the handle, and a fixing bolt is installed on the left end of the upper surface of the handle.

[0011] Preferably, a ratchet is provided on the outer side of the rotating ring, and a pawl is provided inside the mounting ring, and the pawl is made of elastic metal.

[0012] Preferably, the outer surface of the wrench frame is evenly provided with three sets of inserts, and the rotating ring has three sets of matching slots inside.

[0013] Preferably, the outer surface of the wrench frame and the inside of the rotating ring are provided with three sets of slots, and each slot is provided with a magnetic strip.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting an anti-slip structure and setting an anti-slip component on the outside of the handle of the wrench, the grip stability during use can be significantly improved, preventing the hand from slipping, thereby making the operation safer and more reliable; at the same time, it can reduce hand fatigue, improve the efficiency of force application, and maintain good operability and accuracy even in wet, oily or high-load working environments, which helps to extend the service life of the tool and reduce the operational risks.

[0015] 2. In this utility model, by providing a ratchet and a pawl, the rotation of the wrench frame at a single angle can be guaranteed without restriction during use. This allows for easy assembly and disassembly of parts by rotating the wrench frame with the handle. After rotating a certain angle, it can be rotated in the opposite direction without causing the wrench frame to rotate. This facilitates quick and repeated operations without removing the wrench frame. It also allows for quick assembly and disassembly operations at positions with small rotation angles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Reference Figure 1 An embodiment of this utility model is provided: a special wrench for quick filter replacement of generator for tugboats, including a handle 1, an anti-slip structure 2 on the outside of the handle 1, a movable rod 4 inserted at the left end of the handle 1, and an installation ring 6 installed at the left end of the movable rod 4, a rotating ring 7 inside the installation ring 6, and a wrench frame 10 installed inside the rotating ring 7. Specifically, by installing the wrench frame 10 inside the rotating ring 7, and then holding the handle 1, the grip is enhanced by the anti-slip structure 2 to ensure stability during use. Then, the wrench frame 10 is placed on the outside of the part that needs to be adjusted, and the operation is performed by twisting the handle 1.

[0020] Reference Figure 2 The anti-slip structure 2 includes an anti-slip sleeve 201, which is fitted on the outside of the handle 1 and is made of rubber. Multiple anti-slip grooves 202 are evenly arranged on the outer surface of the anti-slip sleeve 201. Specifically, the combination of the rubber anti-slip sleeve 201 and the anti-slip groove 202 can effectively enhance the friction when the operator holds the grip, and can maintain a stable grip even in oily or humid environments in the cabin, preventing slippage and operational deviations.

[0021] Reference Figure 1 An anti-slip rope 3 is provided on the right side of handle 1; Specifically, the anti-slip rope 3 can be worn on the wrist to effectively prevent the handle 1 from slipping off, and the anti-slip rope 3 can be easily hung in a suitable position.

[0022] Reference Figure 1 The movable rod 4 is movably inserted into the left end of the handle 1, and a fixing bolt 5 is installed on the left end of the upper surface of the handle 1; Specifically, the position of the movable rod 4 inside the handle 1 can be adjusted as needed, and then the position of the movable rod 4 can be fixed by the fixing bolt 5. The length of the wrench can be adjusted as needed.

[0023] Reference Figure 4 A ratchet 8 is provided on the outer side of the rotating ring 7, and a pawl 9 is provided inside the mounting ring 6, and the pawl 9 is made of elastic metal. Specifically, by using the elastic metal pawl 9 and the ratchet 8 on the outer side of the rotating ring 7, the rotation angle of the rotating ring 7 can be limited, ensuring that the rotating ring 7 can rotate in one direction. This allows the handle 1 to be quickly restored to its original position and rotated a second time, effectively avoiding the need to adjust the position of the wrench frame 10 multiple times due to the small rotation space.

[0024] Reference Figure 5 The outer surface of the wrench frame 10 is evenly provided with three sets of inserts 11, and the inside of the rotating ring 7 is provided with three sets of matching slots 12. The outer surface of the wrench frame 10 and the inside of the rotating ring 7 are both provided with three sets of slots, and magnetic strips 13 are provided in each slot. Specifically, by using the insertion strip 11 and the slot 12, different wrench frames 10 can be easily replaced as needed. Then, by using the magnetic strip 13, the wrench frame 10 can be fixed inside the rotating ring 7, which makes it easy to replace and fix different wrench slots. Example

[0025] Reference Figure 3 The anti-slip structure 2 includes an anti-slip sleeve 201, which is fitted on the outside of the handle 1 and is made of rubber. Multiple sets of anti-slip balls 203 are evenly arranged on the outer surface of the anti-slip sleeve 201. Specifically, by combining the rubber anti-slip sleeve 201 and the anti-slip ball 203, the friction between the hand and the grip can be enhanced, improving the grip effect and preventing slippage that could cause operational deviations.

[0026] Working principle: Install the appropriate wrench frame 10 into the rotating ring 7 through the cooperation of the insert 11 and the slot 12. Then fix the wrench frame 10 with the magnetic strip 13. Adjust the position of the movable rod 4 at the end of the handle 1 to a suitable length. Then, according to the rotation angle, put the wrench frame 10 on the outside of the part to be adjusted. Operate by twisting the handle 1. Through the cooperation of the ratchet 8 and the pawl 9, the handle 1 can be rotated quickly and multiple times, which can effectively avoid the situation where the rotation space is small and the wrench frame 10 needs to be put on multiple times.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
