Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field, and more particularly, to an assembly tool for assembling handlebars and brakes of a bicycle. Background Art

[0002] In bicycle manufacturing, brake assembly accuracy is directly linked to rider safety and comfort. Traditional brake assembly methods rely primarily on manual labor, with brake components mounted directly to the handlebars. This process is often affected by factors such as worker skill, assembly environment, and component manufacturing accuracy, resulting in significant uncertainty in the accuracy of brake assembly to the handlebars. Specifically, insufficient brake assembly accuracy manifests itself in the following aspects: 1) Positional deviation: Due to the lack of an effective limiting mechanism during assembly, the brake's installation position is prone to deviations, such as left-right asymmetry and front-to-back offset. This not only affects the brake's aesthetic appearance but, more importantly, can lead to unstable braking performance and increase riding risks. 2) Angular deviation: The brake's installation angle is crucial to braking effectiveness. With traditional assembly methods, the inability to precisely control the installation angle means the brake's braking surface may not maintain the optimal angle relationship with the wheel's contact surface, impacting braking distance and force, and reducing riding safety and comfort.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0030] Figure 1 The figure shows an assembly tool for assembling the handlebar 100 and brake 200 of a bicycle provided by the present embodiment, a schematic diagram of the structure of the handlebar 100 and brake 200 of the bicycle involved in the embodiment of the present invention during assembly, and a schematic diagram of the structure of the handlebar 100 and brake 200 of the bicycle involved in the embodiment during assembly. Figure 1 and Figure 2 As shown, this embodiment provides an assembly tool for assembling a handlebar 100 and a brake 200 of a bicycle. The bicycle includes a handlebar 100 and a brake 200 mounted on the handlebar 100. The assembly tool includes a base 1, a first limiting assembly 2, and a second limiting assembly 3. The first limiting assembly 2 is disposed on the base 1 and is capable of limiting the position of the grip tube 101 on the handlebar 100 and the brake 200 mounted on the grip tube 101. The second limiting assembly 3 is disposed on the base 1 and is capable of limiting the position of the connecting tube 102 on the handlebar 100. The first limiting assembly 2 and the second limiting assembly 3 maintain the handlebar 100 in a pre-installed state. The first limiting assembly 2 is capable of limiting the brake 200 in a predetermined position on the grip tube 101, thereby ensuring that the handlebar 100 and brake 200 are in a fixed position after installation.

[0031] This embodiment provides an assembly tool for assembling a bicycle handlebar 100 and brake 200. The tool utilizes a first stopper assembly 2 and a second stopper assembly 3 to hold the handlebar 100 in position on a base 1, maintaining the handlebar 100 in a pre-installed state. Furthermore, the first stopper assembly 2 can hold the brake 200 in a predetermined position when the handlebar 100 is installed (i.e., the brake 200 slides along the grip tube 101 of the handlebar 100), thereby ensuring that the handlebar 100 and brake 200 assembled using the assembly tool are in a uniform, fixed position. By holding the handlebar 100 and brake 200 in position, problems such as positional and angular deviations of the brake 200 after installation are avoided, thereby ensuring the quality of the brake 200 installation. Furthermore, the assembly tool can replace manual positioning of the handlebar 100 and brake 200, thereby improving the efficiency of brake 200 installation to a certain extent.

[0032] Figure 3 FIG. 1 shows an assembly tool for assembling a handlebar 100 and a brake 200 of a bicycle provided by this embodiment. Figure 3 Combined with Figure 1 and Figure 2 As shown, in this embodiment, the first limiting assembly 2 is configured as follows: it includes two first limiting blocks 21 provided on the base 1 and spaced apart, and a limiting space 22 formed between the two first limiting blocks 21 spaced apart and capable of accommodating the gripping tube portion 101, wherein the end faces of the two first limiting blocks 21 close to the gripping tube portion 101 can simultaneously abut against the gripping tube portion 101 to limit the gripping tube portion 101 of the handlebar 100 by abutting against the tube wall of the gripping tube portion 101, and the limiting space 22 can also facilitate the operator to take and place the handlebar 100. In other embodiments, the first limiting assembly 2 can also be configured as: including a first limiting block 21 provided on the base 1 and having a first limiting groove, wherein the first limiting groove can accommodate and fit with the gripping tube portion 101. This setting method can also achieve the limitation of the gripping tube wall and can also facilitate the operator to take and place the handlebar 100. However, compared with the setting method of opening the first limiting groove, the setting method of two first limiting blocks 21 can reduce the process of making the first limiting groove. It is only necessary to install two spaced-apart first limiting blocks 21 during assembly and leave a suitable limiting space 22. Therefore, the setting method of the two first limiting blocks 21 is more conducive to quick assembly.

[0033] It should be noted that in this embodiment, the state of the handlebar 100 to be installed is a state in which it is jointly limited by the first limiting component 2 and the second limiting component 3, and the handlebar 100 can be correctly and smoothly installed. Since there are many different models of bicycles, the state of the handlebar 100 to be installed is also different. The state to be installed can be adjusted accordingly according to actual needs.

[0034] It should be noted that the gripping tube portion 101 on the handlebar 100 is specifically the tube portion of the handlebar 100 for mounting the bicycle grip, and the connecting tube portion 102 on the handlebar 100 is specifically the tube portion connecting the handlebar 100 to the bicycle frame.

[0035] Furthermore, the assembly tool includes two first limiting components 2 symmetrically arranged along the central axis of the connecting tube portion 102 to simultaneously limit the two gripping tube portions 101 on the handlebar 100, so that the handlebar 100 is more stable when being limited.

[0036] Furthermore, the height of the top surface of the first stopper 21 from the top surface of the base 1 is configured to be such that when the brake 200 moves on the handlebar 100, it can abut against the brake 200 and stop the brake 200 at a predetermined position on the grip tube 101. Since the brake 200 is first sleeved onto the handlebar 100 when installed, and then slides a certain distance under its own weight before being fixed to the handlebar 100 via screws or bolts, the brake 200 can be limited in position by simply setting the height of the first stopper 21 to match the height of the predetermined position on the grip tube 101.

[0037] It should be noted that, in this embodiment, the preset position on the grip tube 101 can be any position on the grip tube 101. Since there are many different models of bicycles, the preset positions on the handlebar 100 are also different. The preset positions can be adjusted accordingly according to actual production needs.

[0038] Figure 4 FIG. 1 shows a schematic structural diagram of the base 1 and the second limiting component 3 provided in this embodiment. Figure 4 Combined with Figure 1-Figure 3 As shown, the second limiting assembly 3 includes a second limiting block 31 provided on the base 1 and having a second limiting groove 311, wherein the groove wall of the second limiting groove 311 can fit into the tube wall of the connecting tube part 102, so as to limit the connecting tube part 102 of the handlebar 100 by abutting, and can facilitate the operator to take and place the handlebar 100.

[0039] Furthermore, the second limiting assembly 3 also includes a support plate 32 provided on the base 1, and an adjusting member 33 provided on the support plate 32 and capable of adjusting the second limiting groove 311 to fully fit with the connecting pipe portion 102. By setting the adjusting member 33 to adjust the second limiting groove 311 to fully fit with the pipe wall of the connecting pipe portion 102, the second limiting assembly 3 can be adaptively adjusted according to the installation position of the brake 200 required for different types of bicycles in the actual production process, so as to improve the applicability of the assembly tool.

[0040] Furthermore, the adjusting member 33 is provided with an arc-shaped opening 331. The second limiting assembly 3 also includes a connecting block 34 that is inserted into and movable within the arc-shaped opening 331, a first bolt 35 that is sequentially inserted into the connecting block 34 and the arc-shaped opening 331, a first nut that is threadedly engaged with the first bolt 35, and a connecting rod 36 that is respectively fixedly connected to the connecting block 34 and the second limiting block 31. When the adjusting member 33 is used to adjust the second limiting block 31, the nut can be removed by screwing, pushing the connecting block 34 to slide within the arc-shaped opening 331 to a desired position, thereby driving the second limiting block 31 to move to the desired position. In this manner, the second limiting block 31 can be adjusted to different angles of inclination relative to the base 1 (i.e., the angle between the top surface of the second limiting block 31 and the top surface of the base 1 can be changed), thereby enabling the second limiting groove 311 to accommodate different types of handlebars 100 at different angles.

[0041] Furthermore, a first waist-shaped hole 321 is provided on the support plate 32 along the first direction. The second limiting assembly 3 also includes a second bolt 37 that is inserted into the first waist-shaped hole 321 and can be overlapped by the connecting rod 36, and a second nut that is threadably engaged with the bolt. By adjusting the position of the second bolt 37 in the first waist-shaped hole 321 along the first direction and then overlapping the connecting rod 36 on the second bolt 37 after the position is adjusted, the posture of the second limiting block 31 can be adjusted after the inclination angle of the arc-shaped opening 331 is adjusted so that the second limiting groove 311 can fully fit the connecting pipe portion 102, thereby ensuring that the second limiting groove 311 can achieve the best limiting effect.

[0042] Furthermore, the second limiting assembly 3 also includes an adjustment plate 38 that is detachably connected to the base 1 on one side and fixedly connected to the support plate 32 on the other side, and a third bolt 39 that is sequentially passed through the adjustment plate 38 and the base 1. A second waist-shaped hole 381 is provided on the adjustment plate 38 along the second direction, wherein the second direction is perpendicular to the first direction, so as to adjust the position of the adjustment member 33 along the second direction so that the second limiting groove 311 can be adaptively adjusted along the second direction.

[0043] It should be noted that, in this embodiment, the first direction is the vertical direction, and the second direction is the length direction of the base 1. In other embodiments, the first direction and the second direction can be adaptively adjusted according to whether the base 1 is located on a horizontal plane.

[0044] In this embodiment, the arc-shaped opening 331 has an arc length of three-quarters of a full circle. The side of the adjusting member 33 without the arc-shaped opening 331 is located on the side of the support plate 32 away from the gripping end. This reduces the area of the arc-shaped opening 331 while ensuring the adjustment effect of the adjusting member 33, thereby reducing the processing time of the adjusting member 33. In other embodiments, the arc-shaped opening 331 can also be a full circle or half a circle, etc., and any arc length of the arc-shaped opening 331 that can achieve an adjustment effect on the second limit block 31 is within the scope of the present disclosure.
