Description

Technical Field

[0001] This utility model relates to the field of automotive repair tools, and in particular to a fuel tank cap removal tool. Background Technology

[0002] A typical fuel tank cap has ribs fixed to its outer ring at intervals. The fuel tank cap is threaded to a designated position at the fuel tank opening. The fuel tank cap does not need to be unscrewed when refueling. When the fuel tank needs to be disassembled for maintenance, the fuel tank cap needs to be removed. However, the preload of the fuel tank cap is relatively large and generally cannot be unscrewed manually. The existing patent publication number is (CN202292601U), which discloses an automotive parts disassembly tool. Its purpose is to solve the problem of the difficulty in disassembling a vehicle fuel tank cap, providing manufacturers with a simple and easy-to-use fuel tank cap disassembly tool. Specifically, it adopts the following solution: a fuel tank cap disassembly tool, including a cross-shaped bracket and four identical clamps respectively fixedly installed on the bracket arms of the cross-shaped bracket; Although it can adjust the position of the chucks, it requires adjusting each of the four chucks independently, which is time-consuming, cumbersome and inconvenient.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] This utility model provides a fuel tank cap disassembly tool to solve the technical problem mentioned in the background art, which is that the adjustment requires loosening and adjusting the position distance of the four bolts before tightening them, resulting in inconvenience in adjustment.

[0005] The present invention adopts the following technical solution to solve the above-mentioned technical problems: A fuel tank cap removal tool includes a base plate and an adjusting plate, wherein the adjusting plate is rotatably engaged with the base plate; The base plate has three T-shaped grooves spaced in a ring, and a T-shaped slider slides in the T-shaped grooves. The clamping claw is fixed to the lower end of the T-shaped slider and extends downward from the base plate. The adjustment plate has three adjustment arc grooves spaced in a ring. The lower end of the T-shaped slider is fixed with a guide structure. The guide structure extends into the adjustment arc groove and is tangential to and abuts against the side wall of the adjustment arc groove.

[0006] Preferably, the base plate further includes a threaded post, and the adjusting plate further includes a through hole. The threaded post passes through the through hole from bottom to top, and the threaded post forms a pivot that allows the adjusting plate to rotate relative to the base plate. It also includes a nut, which is threadedly connected to the threaded post and tightened to clamp the adjusting plate and the base plate. When the nut is tightened, the upper end face of the base plate and the lower end face of the adjusting plate are tightly attached and cannot rotate relative to each other.

[0007] Preferably, the base plate is provided with a through groove that runs vertically through the T-shaped slide, and the upper end of the clamping claw passes through the through groove and is fixed to the lower end face of the T-shaped slider.

[0008] Preferably, the clamping claw is fixedly provided with a raised rib protruding from the opposite wall on the side facing the axis of the base plate. During the clamping process of the clamping claw clamping the fuel tank cap, the side wall of the raised rib abuts against the circumferential side wall of the fuel tank cap rib.

[0009] Preferably, the raised ribs are spaced apart, with gaps between adjacent raised ribs, and the width of the gaps is greater than the thickness of the fuel tank cap ribs.

[0010] Preferably, the guide structure includes a roller rotatably disposed on the upper end of the T-shaped slider, the roller being rotatably disposed on the T-shaped slider via a bearing, and the sidewall of the roller rolling against the inner wall of the adjusting arc groove.

[0011] The advantages and positive effects of this utility model are: This device releases the clamping state between the adjusting plate and the base plate by loosening the nut, allowing the base plate to rotate relative to the adjusting plate. The rollers, guided by the trajectory of the adjusting arc groove, adjust their distance from the center axis of the adjusting plate to change the position of the clamping claws. Furthermore, in this device, the three clamping claws move synchronously and in the same direction, quickly forming a clamping size suitable for the fuel tank cap.

[0012] The protruding ribs on the gripping claws abut against the side wall of the fuel tank cap ribs, thus restricting circumferential movement. During disassembly, the nut is turned by wrench, which in turn drives the adjusting plate and the base plate to rotate, thereby rotating the fuel tank cap to achieve disassembly.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance. The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1-4 As shown, the fuel tank cap removal tool of this utility model includes a base plate 19 and an adjusting plate 11, wherein the adjusting plate 11 is rotatably engaged with the base plate 19; The base plate 19 has three T-shaped grooves 14 spaced in a ring, and a T-shaped slider 16 slides within the T-shaped grooves 14. The clamping claw 18 is fixed to the lower end of the T-shaped slider 16 and extends downward from the base plate 19. The adjusting plate 11 has three adjusting arc grooves 12 spaced in a ring. The lower end of the T-shaped slider 16 is fixed with a guide structure. The guide structure extends into the adjusting arc groove 12 and is tangent to the side wall of the adjusting arc groove 12. When the adjusting plate 11 rotates relative to the base plate 19, it pushes the position of the guide structure through the adjusting arc groove 12. Since the guide structure is fixed on the T-shaped slider 16, it can only move along the axial direction of the T-shaped groove 14, thereby adjusting the distance between the clamping claw 18 and the central axis of the base plate 19. In this way, the clamping radius of the clamping claw 18 can be changed.

[0018] Preferably, the base plate 19 further includes a threaded post 24, and the adjusting plate 11 further includes a through hole 13. The threaded post 24 passes through the through hole 13 from bottom to top, forming a pivot that allows the adjusting plate 11 to rotate relative to the base plate 19. It also includes a nut 10, which is threadedly connected to the threaded post 24 and tightened to clamp the adjusting plate 11 and the base plate 19. When the nut 10 is tightened, the upper end face of the base plate 19 and the lower end face of the adjusting plate 11 are tightly pressed together and cannot rotate relative to each other. The T-shaped slider 16 and the clamping claw 18... The position is locked to ensure good stability during the rotation of the fuel tank cover 20 held by this device. Conversely, after disassembly, the nut 10 is loosened, and then the adjusting plate 11 is rotated to adjust the clamping claw 18 outwards to remove the device relative to the fuel tank cover 20. It should also be noted that the tightening direction of the nut 10 and the loosening direction of the fuel tank cover 20 are in the same direction to ensure that the fuel tank cover 20 is loosened and removed during the tightening of the nut 10. After removing the fuel tank cover 20, the nut 10 can be loosened in reverse. The above operation of the nut 10 can be performed by a manual wrench or an electric wrench.

[0019] Preferably, the base plate 19 is provided with a through groove 15 that runs vertically through the T-shaped slide groove 14, and the upper end of the clamping claw 18 passes through the through groove 15 and is fixed to the lower end face of the T-shaped slider 16.

[0020] Preferably, the clamping claw 18 is fixedly provided with a raised rib 23 (e.g., protruding from the wall) on the side facing the axis of the base disk 19. Figure 4 During the clamping process of the clamping claw 18 clamping the fuel tank cap 20, the side wall of the protruding rib 23 abuts against the circumferential side wall of the fuel tank cap rib 21. This facilitates the clamping claw 18 to transmit torque to the fuel tank cap rib 21 when rotating around the axis of the base plate 19, thereby driving the fuel tank cap 20 to rotate and loosen. Compared with the bare inner wall structure in the prior art, it has better torque transmission stability.

[0021] Preferably, the raised ribs 23 are spaced apart, and there is a gap between adjacent raised ribs 23, and the width of the gap is greater than the thickness of the fuel tank cap rib 21.

[0022] Preferably, the guide structure can be a cylindrical metal rod or a roller 17 rotatably mounted on the upper end of the T-shaped slider 16. The roller 17 is rotatably mounted on the T-shaped slider 16 via a bearing. The side wall of the roller 17 rolls against the inner wall of the adjusting arc groove 12. In this way, after rotating the adjusting disk 11, the contact between the roller 17 and the inner wall of the adjusting arc groove 12 effectively improves the smoothness of the movement at that point.

[0023] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
