Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bicycle repair tools, specifically, it relates to a combination tool for tire lifter and brake piston reset. Background Technology
[0002] A bicycle repair tool kit includes a tire lever, spoke wrench, chain removal and installation tools, freewheel removal and installation tools, and piston reset tools. For easy carrying and quick access, these tools of similar shape and size are usually integrated and stored in a dedicated repair bag.
[0003] Tire levers are extremely common when handling bicycle tires, so repair kits often include several for emergencies. However, due to their design, tire levers typically function as both pry bars and hooks at their ends. While this enhances the tool's practicality, it also introduces new problems. Specifically, when multiple tire levers are stacked together, the presence of the pry bar and hook creates relatively large gaps between them. These gaps not only increase the overall space occupied by the tire levers but also reduce the utilization rate of the repair kit's internal storage space.
[0004] This situation negatively impacts the storage of other bicycle repair tools within the repair kit, potentially leading to ineffective storage or the need for unnecessary adjustments and rearrangements when needed, thus reducing the efficiency and convenience of repair work. Therefore, how to more effectively utilize the storage space within the repair kit, especially reducing space waste when storing tire levers, has become an urgent problem to be solved. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combination tool for tire rocker and brake piston reset.
[0006] A bicycle tire consists of a hub, rim, tire, inner tube, and valve. The rim is located on the outer edge of the wheel, supports the tire, and connects to the spokes. The hook is usually hook-shaped or curved, similar to a "J" or "L" shape. This invention uses an "L" shaped hook. When using the hook to push the tire back into the wheel, it needs to hook onto the edge of the rim to prevent the pry bar from slipping during operation. Then, by pushing the hook to move it one full circle along the circumference of the rim, the tire can be installed.
[0007] The pry bar is usually flat or slightly curved, similar to the head of a shovel. The pry bar used in this invention is slightly curved, with a smooth curved surface on the edge and a certain thickness, so that it can be easily inserted into the gap between the tire and the rim, thereby prying the tire out of the rim.
[0008] The hook and pry bar are integrally molded.
[0009] A bicycle piston reset tool is a standalone repair tool primarily used to push the brake piston back into the brake caliper during the maintenance or repair of a bicycle's braking system, in order to replace the brake pads.
[0010] A brake caliper is a fixed component mounted on the frame or fork of a bicycle. It contains a piston and brake pads and is used to clamp the brake disc.
[0011] Hydraulic disc brake calipers are key components of hydraulic disc brake systems. They transmit pressure via hydraulic fluid, pushing a piston within the caliper to clamp the brake pads onto the brake disc, thus achieving braking. The hydraulic disc brake caliper is part of the brake caliper, or rather, a component closely connected to it. When the rider squeezes the brake lever, the hydraulic system within the caliper transmits pressure to the brake caliper, causing the piston within the caliper to push the brake pads to clamp onto the brake disc. The brake caliper is the actuating component of the hydraulic disc brake caliper; without the caliper, the hydraulic disc brake caliper cannot perform the braking action.
[0012] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:
[0013] The handle has an inclined contact surface, which is used at least for the brake piston to push back the brake caliper. A hook and a pry head are provided opposite to each other at the end of the handle away from the contact surface. A bleed needle for venting tires is provided inside the hook.
[0014] In this invention, by holding two tire levers, inserting the handles into the hydraulic disc caliper of the brake caliper so that the contact surface contacts the piston, and by applying force to the tire levers, the piston can be pushed back into the brake caliper by the contact surfaces on the two handles.
[0015] Preferably, the pry head and the mating surface are located on the same side.
[0016] In this invention, the more protruding part of the tire lever is the lever head, and the flatter part is the hook. By setting the contact surface on the same side of the lever head, two tire levers can be inverted and attached to each other to form a set of tire levers. In the stacking of each set of tire levers, the lever head of one set of tire levers is connected to the hook of the other set of tire levers, thereby reducing the stacking space gap and further reducing the space occupied by the tire levers.
[0017] Preferably, the hook has a vent in the middle, the vent needle is integrally formed and disposed in the vent, and the vent needle is adapted to the air nozzle;
[0018] Preferably, a deep groove is provided between the hook and the handle so that the hook can hook onto the edge of the tire rim through the deep groove.
[0019] Preferably, the handle has multiple hollow slots that extend through it, and the multiple hollow slots are distributed sequentially along the length of the handle, and the multiple hollow slots are equidistant from each other.
[0020] Preferably, the handle has multiple weight-reducing openings at the end near the hook.
[0021] Preferably, a hanging hole is provided through the handle, and the hanging hole is located at the end of the handle away from the hook.
[0022] Compared with the prior art, the advantages of this utility model include:
[0023] (1) The present invention provides a combination tool for tire lifting bar and brake piston reset, which has a simple structure and is easy to operate. The air release needle set in the hook can easily release the gas inside the inner tube of the wheel during maintenance.
[0024] (2) The present invention provides a combination tool for tire lever and brake piston reset. By setting the hook and pry head of the tire lever opposite to each other, and using the handle and the contact surface together, the piston reset tool can push the brake piston back to the brake caliper. This allows the tire lever and the piston reset tool to be combined together, so that one tool can simultaneously have the functions of tire lever, piston reset tool combination and air valve exhaust function. This reduces the volume occupied by the tools inside the repair kit, further avoids the waste of the internal storage space of the repair kit, and improves the utilization rate of the internal storage space of the repair kit.

Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components in the tire lever and piston reset tool in this utility model embodiment can be selected according to specific circumstances, and no special limitations or explanations are made here.
[0038] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions. Example
[0039] Please see Figure 1 and Figure 2 A combination tool for tire lever and brake piston reset includes a handle 1, on which a contact surface 8 is inclinedly provided. The contact surface 8 is used at least for the brake piston to push back the brake caliper. A hook 5 and a pry head 7 are provided opposite to each other at the end of the handle 1 away from the contact surface 8. An air bleed needle 6 for tire venting is provided inside the hook 5.
[0040] Specifically, the pry head 7 and the mating surface 8 are located on the same side. The more convex part of the tire lever is the pry head 7, and the more flat part is the hook 5. By setting the mating surface 8 on the same side of the pry head 7, two tire levers can be inverted and mated together to form a set of tire levers. In the stacking of each set of tire levers, the pry head 7 of one set of tire levers is connected to the hook 5 of the other set of tire levers, thereby reducing the stacking space gap and further reducing the space occupied by the tire levers.
[0041] Specifically, a pry bar 11 is fixedly connected to one side of the pry head 7. The pry bar 11 can provide a support point for the pry head 7 when it is in use, so that the pry head 7 can easily pry out the tire. An arc-shaped surface 9 is provided between the pry head 7 and the handle 1. The curvature of the arc-shaped surface 9 matches the curvature of the tire sidewall, so that the pry head 7 can fit against the tire sidewall and easily pry it up and remove it.
[0042] Please see Figure 3 and Figure 4The hook 5 has an air vent in the middle, and the vent needle 6 is integrally formed and installed in the air vent. When in use, the vent needle 6 can be inserted into the valve to release the air from inside the inner tube.
[0043] Please see Figure 1 A deep groove 10 is provided between the hook 5 and the handle 1 so that the hook 5 can hook onto the edge of the tire rim through the deep groove 10, thereby pushing the tire into the rim through the hook 5, and then pushing the hook 5 to move along the circumference of the rim once to complete the tire installation.
[0044] Specifically, a plurality of hollow slots 3 are provided through the handle 1, and the plurality of hollow slots 3 are distributed sequentially along the length of the handle 1 and are equidistant from each other. In this embodiment, the specific number of hollow slots 3 is 4. A plurality of weight-reducing openings 4 are provided at the end of the handle 1 near the hook 5. In this embodiment, the specific number of weight-reducing openings 4 is 4. Under the premise of maintaining the structural strength required for the use of the tire lever, the amount of raw materials used in the production of the tire lever is reduced by providing a plurality of hollow slots 3 and weight-reducing openings 4, thereby reducing the overall weight of the tire lever and making the tire lever lighter and more convenient to handle and use.
[0045] Please see Figure 1 The handle 1 has a through-hole 2. The through-hole 2 is located at the end of the handle 1 away from the hook 5. In addition to storing the tire lever in a dedicated repair kit, the tire lever can also be hung on the wall through the through-hole 2. There are many ways to hang it, such as: nailing a nail into the wall and then fitting the through-hole 2 onto the nail to hang the tire lever.
[0046] The specific implementation method of using a tire lever for brake piston reset is as follows:
[0047] By holding two tire levers, inserting handle 1 into the hydraulic disc chuck 12 of the brake caliper so that the contact surface 8 contacts the piston, and by applying force to the tire levers, the piston can be pushed back into the brake caliper by the contact surface 8 on the two handles 1, thus completing the function of the piston reset tool.
[0048] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
