[0002] Fuel pump locking plates (or baffles) are mainly installed inside the filler neck of a car's fuel tank. Their core functions include: preventing foreign objects from entering, preventing dust, impurities, etc. from falling into the fuel tank during refueling, and avoiding fuel pump malfunctions caused by sucking in foreign objects (such as motor seizure or fuel line blockage); and preventing rollover leakage, in the event of a vehicle rollover or severe collision, the locking plates can temporarily seal the fuel tank opening, reducing the risk of fuel leakage and lowering the fire hazard.

[0003] In automotive fuel supply systems, fuel filters are divided into two types: internal and external. Internal fuel filters are located inside the engine oil tank, and when replacing them, the fuel pump lock plate needs to be removed and the fuel pump taken out before replacement can be performed.

[0004] In existing technologies, the disassembly or assembly of fuel pump lock plates requires 1-2 technicians to perform the disassembly or assembly operations using a flathead screwdriver and a hammer. During the operation, two technicians use a flathead screwdriver to hold the lock plate at a 180-degree symmetrical position and strike the screwdriver with a hammer to cause the lock plate to rotate and shift, thereby completing the disassembly or assembly work. Traditional disassembly and assembly processes not only easily cause irreversible damage to the lock plate, but also increase the difficulty and workload of the technicians.

[0005] To address this issue, an adjustable fuel pump lock plate disassembly device is proposed to solve the problems existing in the prior art. Utility Model Content

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0014] Please see Figure 1 This utility model provides an adjustable fuel pump lock plate disassembly device, the technical solution of which is as follows: The device includes a fixed carrier plate 1, which is triangular in shape and has an equilateral triangle design. Three adjusting angle rods 2 are evenly distributed on the fixed carrier plate 1, and the three adjusting angle rods 2 are respectively located at the three corners of the fixed carrier plate 1. The fixed carrier plate 1 has a pre-set universal connection hole, and each adjusting angle rod 2 is connected to the fixed carrier plate 1 through a locking mechanism. Each adjusting angle rod 2 has a screwdriver bit 3 at its lower end.

[0015] The device employs an equilateral triangular fixed carrier plate 1, cast from high-strength steel. Utilizing the stable structural characteristics of a triangle, it evenly distributes force across the three adjustment rods 2 during installation. Compared to traditional methods, this avoids damage to the locking plates and related components caused by uneven force distribution, ensuring the integrity of the locking plates and related parts. The fixed carrier plate 1 has three evenly distributed adjustment rods 2 with universal connection holes, connected via a locking mechanism. This allows for adaptation to the disassembly and assembly needs of fuel pump locking plates of different specifications, with flexible position adjustments. This solves the problem of poor compatibility with traditional tools, improving the device's versatility and making it suitable for disassembly and assembly of fuel pump locking plates in various vehicle models. Each adjustment rod 2 has a screwdriver bit 3 at its lower end, replacing the traditional flathead screwdriver and hammer combination. A single person can precisely apply force to the locking plates to complete disassembly and assembly, reducing operational difficulty, decreasing reliance on the number and physical strength of repair technicians, improving disassembly and assembly efficiency, and reducing workload.

[0016] The locking mechanism includes an upper bolt 4 fitted onto the top of each adjusting angle rod 2, and a lower bolt 5 on each adjusting angle rod 2, with the lower bolt 5 close to the bottom of the fixed carrier plate 1. That is, the adjusting angle rod 2 is connected and fixed to the fixed carrier plate 1 by the upper bolt 4 and the lower bolt 5.

[0017] By using the upper bolt 4 to set the top of the adjusting angle rod 2 and the lower bolt 5 to be close to the bottom of the fixed carrier plate 1 as double limiting devices, the adjusting angle rod 2 can be firmly connected to the fixed carrier plate 1, ensuring that the adjusting angle rod 2 will not shift or shake during construction, guaranteeing stable force transmission during disassembly and assembly operations, making the disassembly and assembly of the locking plate precise and controllable, and improving the overall reliability of the device. This structure can easily adjust the position and height of the adjusting angle rod 2 relative to the fixed carrier plate 1, and can be flexibly adapted to the disassembly and assembly requirements of fuel pump locking plates of different models and specifications, solving the problem that traditional tools cannot be flexibly adjusted and adapted, and enhancing the applicability of the device to various working conditions.

[0018] The fixed carrier plate 1 has three guide grooves 6, which are evenly distributed at the three corners of the fixed carrier plate 1. Each of the adjustment angle rods 2 is set in the corresponding guide groove 6, and the position of the adjustment angle rod can be controlled by adjusting the tightening degree.

[0019] The guide groove 6 provides adjustable space for the adjustment rod 2, allowing for flexible adjustment of the position of the adjustment rod 2 according to the size and installation position differences of the fuel pump locking plate of different vehicle models. This adapts to the disassembly and assembly needs of various locking plate specifications, breaking through the limitations of traditional tool compatibility and expanding the application range of the device. Maintenance personnel can precisely control the position of the adjustment rod 2 in the guide groove 6 by adjusting the tightening degree, ensuring that the screwdriver bit 3 is accurately aligned with the locking plate locking mouth. This replaces the traditional method of finding the symmetrical alignment based on experience, improving operational accuracy and reducing the probability of locking plate damage or operation failure due to misalignment.

[0020] Each bit 3 is detachably connected to the corresponding adjustment rod 2, and each bit 3 is threadedly connected to the corresponding adjustment rod 2. Because different vehicle models and fuel pump lock plates have different requirements for the size and model of the bit 3, the detachable and threaded connection between the bit 3 and the adjustment rod 2 allows maintenance personnel to quickly replace the appropriate bit 3 according to actual disassembly and assembly needs without replacing the entire device, thus improving the device's adaptability to various fuel pump lock plate disassembly and assembly scenarios.

[0021] Each upper bolt 4 is provided with a washer 7 between it and the fixed carrier plate 1. The washer 7 can increase the contact area between the upper bolt 4 and the fixed carrier plate 1, so that the locking force is transmitted to the fixed carrier plate 1 more evenly, avoid the upper bolt 4 directly squeezing the fixed carrier plate 1 to avoid excessive local stress, prevent the fixed carrier plate 1 from deforming or indenting, and thus ensure the stability of the connection between the adjusting angle rod column 2 and the fixed carrier plate 1, and reduce the shaking of the device caused by loose connection during construction.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
