Description

Technical Field

[0001] This utility model relates to the field of racing car repair technology, and more specifically, to a quick-release tool assembly. Background Technology

[0002] Racing cars are two-wheeled vehicles driven primarily by human power. The rider pedals, which drives the transmission system (chain, gears) to rotate the rear wheel, thus propelling the vehicle forward.

[0003] However, traditional tools have significant shortcomings in the current process of maintaining and dismantling racing cars:

[0004] Tools are scattered and inconvenient to carry: Different parts of the race car (wheel axle nuts, foot pedal hex bolts, frame Phillips bolts) require different tools (open-end wrenches, hex wrenches, screwdrivers, etc.). Users need to carry multiple independent tools, which not only increases the weight of the trip, but also makes the tools scattered and easy to lose, taking up extra space in backpacks or tool bags.

[0005] Disassembling racing car parts requires frequent tool switching (e.g., to remove the rear wheel, you need to first use a wrench to loosen the wheel axle nut, and then use a screwdriver to remove the brake screws). The operation involves many steps and is time-consuming. Traditional tools are difficult to meet the efficiency requirements, especially for commuters who need to "quickly disassemble and reassemble" or "temporarily remove wheels before entering the subway station". Therefore, a quick-disassembly tool assembly is provided. Utility Model Content

[0022] 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.

[0023] This embodiment discloses a quick-release tool assembly, which aims to solve the problem of having to carry multiple tools and cumbersome disassembly steps when maintaining existing racing cars. By integrating a support structure and multifunctional disassembly components, it enables the quick disassembly of common racing car components such as wheel axles and screws, while taking into account both portability and structural stability.

[0024] The overall structure of this quick-release tool assembly is shown in the attached figure. Figure 1 Appendix Figure 2 As shown, the core includes a first connecting plate 1, a second connecting plate 2, and a support component disposed on both, supplemented by a reinforcing bending plate 9, a limiting protrusion 10, and a limiting pin 11, making it easy to store in a racing tool kit.

[0025] The first connecting plate 1 is cut from a steel plate and has a reserved operating area at one end for easy hand-held force application. The second connecting plate 2 is welded to one end of the first connecting plate 1 by fillet weld to ensure support stability.

[0026] As attached Figure 3 As shown, the reinforcing bending plate 9 is welded to both sides of the first connecting plate 1. After welding, the two right-angled surfaces of the reinforcing bending plate 9 are respectively attached to the plate surface and side surface of the connecting plate to avoid deformation of the connecting plate due to excessive force during disassembly.

[0027] Support components are the core functional parts of the tool, as shown in the attached document. Figure 1 Appendix Figure 3 Appendix Figure 4 As shown, the specific structure is as follows:

[0028] Two first limiting frames 3 are configured and welded side-by-side to the upper surface of the first connecting plate 1. Each first limiting frame 3 has a "U"-shaped structure, with symmetrical limiting protrusions 10 on both sides of its inner wall as shown in the attached figure. Figure 3 As shown, the vertical cross-section of the limiting protrusion 10 is arc-shaped, which serves to limit the first disassembly rod 4 to the left and right to prevent it from swaying laterally.

[0029] The first disassembly rod 4 passes through the "U"-shaped openings of the two first limiting frames 3, and its outer wall is closely fitted with the arc-shaped surface of the limiting protrusion 10 to ensure assembly stability.

[0030] The second limiting frame 5 has the same structure as the first limiting frame 3, but it is welded to the upper surface of the second connecting plate 2 and is higher than the first limiting frame 3 to accommodate the horizontal position of the second disassembly rod 6; arc-shaped limiting protrusions 10 are also provided on both sides of its inner wall, and the opening width is the same as that of the first limiting frame 3.

[0031] Second disassembly lever 6, as shown in the attached document. Figure 1 Appendix Figure 4 As shown, a U-shaped opening is horizontally inserted through the second limiting frame 5, and its axis is perpendicular to the axis of the first disassembly rod 4, forming a cross shape, and is located directly above the first disassembly rod 4; the outer wall of the second disassembly rod 6 is tightly fitted with the limiting protrusion 10 of the second limiting frame 5 to prevent lateral displacement.

[0032] As attached Figure 4 As shown, the disassembly head 7 and the disassembly sleeve 8 are respectively fixed to both ends of the second disassembly rod 6, forming a multi-functional disassembly structure:

[0033] Disassembly head 7: It is fixed to one end of the second disassembly rod 6 by welding or interference fit. Its end is set with an internal hexagonal slot, which can also be replaced with a slotted or cross slot structure according to actual needs. It is used to remove screws from parts such as racing car frame and foot pedal.

[0034] Disassembly sleeve 8: It is a cylindrical structure that is welded to the other end of the second disassembly rod 6. Its inner wall is provided with anti-slip texture to increase the friction with the nut and prevent slippage during disassembly.

[0035] As attached Figure 3 As shown, each of the first limiting frame 3 and the second limiting frame 5 has a through hole at the bottom of its inner wall. The bottom end of the limiting pin 11 passes through the through hole of the limiting frame and the corresponding through hole of the connecting plate in sequence, and is rotatably connected to the connecting plate by interference fit. The top end of the limiting pin 11 is higher than the bottom of the inner wall of the limiting frame. Its function is to form a bottom support for the first disassembly rod 4 and the second disassembly rod 6, and at the same time allow the disassembly rod to rotate slightly when force is applied to adapt to the change of disassembly angle, so as to avoid hard contact that could damage the parts.

[0036] The specific working principle is as follows: disassembling the race car's wheel axle;

[0037] Holding the blank end of the first connecting plate 1, put the disassembly sleeve 8 at one end of the second disassembly rod 6 onto the nut of the racing wheel axle, such as the rear wheel axle nut, and ensure that the inner wall of the disassembly sleeve 8 is completely in contact with the nut;

[0038] Adjust the position of the first disassembly lever 4 so that one end of it abuts against a rigid part of the racing car frame, such as the rear fork interface, to form a fulcrum;

[0039] A downward force is applied to the end of the second disassembly rod 6 away from the disassembly sleeve 8. Using the "cross" structure of the first disassembly rod 4 and the second disassembly rod 6, and with the limit pin 11 as an auxiliary fulcrum, the force is amplified by lever, and the wheel axle nut is quickly loosened to complete the wheel axle disassembly.

[0040] Disassembling racing car screws such as pedal screws;

[0041] Align the disassembly head 7 at one end of the second disassembly lever 6 with the hex socket screw on the foot pedal, ensuring that the hex socket of the disassembly head 7 is fully engaged with the screw;

[0042] Hold the first connecting plate 1 and the first disassembly rod 4 with your hands to keep them fixed and prevent the tool from shaking as a whole;

[0043] Rotate the second disassembly rod 6 counterclockwise along the screw disassembly direction. At this time, the limiting protrusion 10 of the second limiting bracket 5 restricts the lateral displacement of the second disassembly rod 6, and the limiting pin 11 allows the disassembly rod to rotate slightly, ensuring that the force is concentrated on the screw and achieving rapid disassembly.

[0044] During the disassembly process described above, the left hand can grasp the disassembly sleeve 8, the right hand can grasp the first disassembly rod 4, and the disassembly head 7 can be inserted into the nut to rotate the disassembly sleeve 8 clockwise or counterclockwise, thereby quickly removing the racing car locking parts.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
