Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of assembly tools for bicycle handlebar assemblies, and more specifically, the present utility model relates to an assembly tool for a bicycle handlebar assembly. Background Art

[0002] In the bicycle manufacturing industry, the handlebar assembly is the main control component during riding. Its stability and adjustability are crucial to the riding experience and safety. At present, the common handlebar assembly on the market usually consists of a crossbar tube and a stem tube. The connection between the two parts is mostly a mechanical fixed connection method (that is, the stem tube is connected to the crossbar tube and fastened by fasteners such as screws or bolts). The crossbar tube in the prior art is usually designed as an M-shaped circular tube with multiple bends to facilitate the rider's grip. Since the crossbar tube and stem tube need to be installed on the front tube of the bicycle after assembly, it is necessary to rotate the crossbar tube about its own axis to a specific position before the stem tube is connected to the crossbar tube during assembly. This makes the crossbar tube ergonomic and convenient for the rider to grip the bicycle.

[0003] The existing assembly method is usually manual assembly. Due to differences in operator skills and experience, it is difficult to ensure that each handlebar crossbar is assembled with the handlebar stem at the same rotation angle, resulting in uneven assembly accuracy of the assembled handlebar assembly. Disassembly and reassembly are required, which seriously affects the assembly efficiency of the handlebar assembly. Utility Model Content

[0004] In order to solve one or more of the technical problems mentioned above, the present invention provides an assembly tool for a handlebar assembly of a bicycle, which replaces manual work of holding the cross tube and the stem in specific positions, thereby improving the assembly efficiency of the handlebar assembly.

[0005] The present invention provides an assembly tool for a bicycle handlebar assembly, which is used to position a stem tube and a crossbar tube of the handlebar assembly that are connected to each other for assembly. The assembly tool includes:

[0006] An assembly tool for a bicycle handlebar assembly is used to positionally limit a stem tube and a crossbar tube of a handlebar assembly that are connected to each other for assembly. The assembly tool comprises:

[0007] platform;

[0008] a first limiting assembly, which is provided on the platform and can limit at least one end of the handlebar tube when the stem tube and the handlebar tube are assembled, and can limit both ends of the handlebar tube after the stem tube and the handlebar tube are assembled to maintain the handlebar tube in a first predetermined position; and

[0009] The second limiting assembly is arranged on the platform and can fix the stem tube so that the stem tube can be kept at a second predetermined position after being sleeved on the handlebar tube.

[0010] Furthermore, the first limiting assembly includes at least two first limiting blocks provided on the platform and capable of limiting the connected handlebar tube, wherein the first limiting blocks are provided with first limiting grooves capable of fitting with the outer wall of the handlebar tube.

[0011] Furthermore, at least two of the first limiting blocks are spaced apart to provide installation space for the connecting portion located in the middle of the handlebar tube.

[0013] Furthermore, at least two first limiting blocks arranged at intervals can abut against two ends of the connecting portion along the axial direction of the handlebar tube.

[0014] Furthermore, the first limiting assembly also includes a first connecting plate connected to the platform and the first limiting block respectively, and a first bolt sequentially passed through the first connecting plate and the first limiting block, so that the first limiting block can rotate around the connection point between it and the first bolt and be fixed by the first bolt.

[0015] Furthermore, the second limiting assembly includes at least two third limiting blocks provided on the platform and capable of limiting the handlebar tube, wherein the third limiting blocks are provided with third limiting grooves capable of fitting with the outer wall of the handlebar tube.

[0016] Furthermore, the second limiting assembly also includes a second connecting plate connected to the platform and the third limiting block, and a second bolt sequentially passed through the second connecting plate and the third limiting block, so that the third limiting block can rotate around the connection point between it and the second bolt and be fixed by the second bolt.

[0017] Furthermore, the cross-sectional shape of the first limiting groove and the second limiting groove along the axial direction of the handlebar tube is semicircular, and the cross-sectional shape of the third limiting groove along the axial direction of the stem tube is semicircular.

[0018] Furthermore, the first limiting block, the second limiting block and the third limiting block are made of wood or polyurethane.

[0019] In the assembly tool provided in this embodiment, the first stop assembly not only allows the handlebar tube to be sleeved onto the handlebar tube before the operator fully secures the handlebar tube, but also maintains the handlebar tube in a first predetermined position after the handlebar tube is sleeved onto the handlebar tube, and also maintains the stem tube sleeved onto the handlebar tube in a second predetermined position, thereby ensuring that each handlebar tube and stem tube assembled using this assembly tool have the same shape. This assembly tool replaces the prior art method of manually rotating the handlebar tube and then sleeved onto the stem tube, ensuring that each handlebar tube assembled using the assembly tool provided in this embodiment sleeves onto the stem tube in the same position. This avoids the problem of insufficient assembly precision between the handlebar tube and stem tube, which may require rework due to differences in operator skill and experience, and greatly improves the assembly efficiency of the handlebar assembly.

[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 a bicycle handlebar assembly provided by the embodiment and a schematic structural diagram of the handlebar assembly involved in the embodiment of the utility model. Figure 2 FIG. 1 shows a schematic structural diagram of the handlebar assembly provided in this embodiment, wherein the handlebar assembly includes a horizontal tube 100 and a vertical tube 200. Figure 1 Combined with Figure 2 As shown, this embodiment provides an assembly tool for a bicycle handlebar assembly. The assembly tool is used to positionally limit the stem tube 200 and the cross tube 100 of the handlebar assembly, which are connected to each other, to facilitate assembly. The assembly tool includes a platform 1, a first position-limiting assembly 2, and a second position-limiting assembly 3. The first position-limiting assembly 2 is disposed on the platform 1 and is capable of limiting the position of at least one end of the cross tube 100 during assembly of the stem tube 200 and cross tube 100. After assembly, the first position-limiting assembly 2 is capable of securing both ends of the cross tube 100 to maintain the cross tube 100 in a first predetermined position. The second position-limiting assembly 3 is disposed on the platform 1 and is capable of securing the stem tube 200 so that the stem tube 200 remains in a second predetermined position after being connected to the cross tube 100.

[0031] It should be noted that the specific shape of the handlebar tube 100 involved in this embodiment is an M-shaped bent tube that is convenient for the rider to hold, and the stem tube 200 involved in this embodiment is a V-shaped bent tube. The first predetermined position is to rotate the handlebar tube 100 along its own axis to a pre-installation position that makes the two ends of the handlebar tube 100 more convenient for the rider to hold, and the second predetermined position keeps the handlebar tube 100 in the pre-installation position that is convenient for the rider to hold after being installed on the bicycle.

[0032] In the assembly tool provided by this embodiment, the first stopper assembly 2 can not only sleeve the handlebar tube 200 onto the crossbar tube 100 before the operator fully secures the crossbar tube 100, but also maintain the crossbar tube 100 in a first predetermined position after the crossbar tube 100 is sleeved onto the stem tube 200, and can also maintain the stem tube 200 sleeved onto the crossbar tube 100 in a second predetermined position, thereby ensuring that each set of crossbar tubes 100 and stem tubes 200 assembled using this assembly tool have the same shape. This assembly tool replaces the prior art method of manually rotating the crossbar tube 100 and then sleeved onto the stem tube 200, ensuring that each crossbar tube 100 assembled using the assembly tool provided by this embodiment can be sleeved onto the stem tube 200 in the same position, thereby avoiding the problem of insufficient assembly precision of the crossbar tube 100 and stem tube 200 due to differences in operator skills and experience, which requires rework, greatly improving the assembly efficiency of the handlebar assembly.

[0033] Figure 3 An assembly tool for a bicycle handlebar assembly provided by this embodiment is shown. Figure 3 Combined with Figure 1 and Figure 2 As shown, the first limiting assembly 2 includes at least two first limiting blocks 21 provided on the platform 1 and capable of limiting the handlebar tube 100 after being sleeved, wherein the first limiting block 21 is provided with a first limiting groove 211 which can fit with the outer wall of the handlebar tube 100, so as to limit the movement of the handlebar tube 100 along its own radial direction after the handlebar tube 100 is inserted, and limit the rotation of the handlebar tube 100 about the midpoint of its own axis. The limiting method of the limiting groove is more convenient for the operator to place or remove the handlebar tube 100 than a mechanical structure with a limiting function such as a clamping mechanism.

[0034] Furthermore, at least two first limit blocks 21 are spaced apart to provide installation space for the connection portion 101 located in the middle of the handlebar tube 100, thereby providing operating space for the operator to perform a tightening operation after the stem tube 200 is sleeved on the connection portion 101 of the handlebar tube 100, thereby facilitating the operator to tighten the sleeved stem tube 200 to the handlebar tube 100.

[0035] Furthermore, the first limiting assembly 2 also includes a first connecting piece 23 connected to the platform 1 and the first limiting block 21, respectively, and a first bolt 24 sequentially inserted through the first connecting piece 23 and the first limiting block 21. This allows the first limiting block 21 to rotate about its connection point with the first bolt 24 and be secured by the first bolt 24. Before positioning the handlebar tube 100, the first limiting block 21 is adjusted by loosening the first bolt 24 and rotating it about its connection point with the first bolt 24 to adjust the position of the first limiting slot 211 on the first limiting block 21. After adjusting the position of the first limiting slot 211, the first bolt 24 is tightened. This allows the first limiting block 21 to adapt to the shape of the handlebar tube 100 and to position the handlebar tube 100. Furthermore, the position of the first limiting block 21 can be adjusted accordingly when assembling different types of handlebar tubes 100, thereby improving the applicability of the first limiting assembly 2. Moreover, the adjustment method of loosening or tightening the bolts is easier to operate and has lower production costs than other forms of angle adjustment mechanisms.

[0036] Specifically, the handlebar tube 100 includes a bent portion 102 and a gripping end 103 located on either side of the connecting portion 101 and extending in sequence away from the connecting portion 101. The first limiting assembly 2 also includes at least two second limiting blocks 22 fixedly mounted on the platform 1. The second limiting blocks 22 are provided with second limiting grooves 221 that engage with the outer wall of the gripping end 103. The first limiting grooves 211 engage with the wall between the bent portion 102 and the connecting portion 101 of the handlebar tube 100. The first limiting blocks 21 restrict the wall between the bent portion 102 and the connecting portion 101 of the handlebar tube 100, while the second limiting blocks 22 restrict the gripping end 103 of the handlebar tube 100, thereby limiting rotation of the handlebar tube 100 about its own axis. These limiting blocks, in conjunction with the first limiting blocks 21, ensure that the handlebar tube 100 is maintained in the first predetermined position, improving assembly accuracy with the stem tube 200.

[0037] Furthermore, at least two first stoppers 21 spaced apart can abut against both ends of the connecting portion 101 along the axial direction of the crossbar tube 100. This prevents the crossbar tube 100 from deviating along its own axis without affecting the fixing operation of the crossbar tube 100 and the stem tube 200 after the crossbar tube 100 is connected, thereby preventing the crossbar tube 100 from moving along its own axis during the limiting operation.

[0038] Furthermore, the second limiting assembly 3 includes at least two third limiting blocks 31 disposed on the platform 1 and capable of limiting the position of the stem tube 200. The third limiting blocks 31 are provided with third limiting grooves that engage the outer wall of the stem tube 200, thereby limiting rotation of the stem tube 200 about its own axial midpoint and radial rotation, thereby ensuring that the stem tube 200 is maintained in the second predetermined position. Compared to mechanical limiting structures such as clamping mechanisms, the limiting grooves make it easier for operators to place or remove the stem tube 200.

[0039] It should be noted that, since one end of the stem tube 200 needs to be sleeved onto the handlebar tube 100, there is no need to provide a special structure to restrict the rotation of the stem tube 200 about its own axial direction (i.e., after the stem tube 200 is sleeved onto the handlebar tube 100, the rotation of the stem tube 200 about its own axial direction can be restricted).

[0040] Furthermore, the second limiting assembly 3 includes a second connecting piece 32 connected to the platform 1 and the third limiting block 31, and a second bolt 33 sequentially inserted through the second connecting piece 32 and the third limiting block 31. This allows the third limiting block 31 to rotate about its connection point with the second bolt 33 and be secured by the second bolt 33. Before positioning the stem tube 200, the position of the third limiting slot of the third limiting block 31 is adjusted by loosening the second bolt 33 and adjusting the first limiting block 21 about its connection point with the second bolt 33. After adjusting the position of the third limiting slot, the second bolt 33 is tightened. This allows the third limiting block 31 to adapt to the shape of the stem tube 200 and constrain the stem tube 200. The position of the third limiting block 31 can also be adjusted to accommodate different types of stem tubes 200, thereby improving the applicability of the second limiting assembly 3. Furthermore, this adjustment method, which involves loosening or tightening the bolt, is more convenient to operate and less expensive to manufacture than other angle adjustment mechanisms.

[0041] Furthermore, the cross-sectional shape of the first limiting groove 211 and the second limiting groove 221 along the axial direction of the cross tube 100 is semicircular, and the cross-sectional shape of the third limiting groove along the axial direction of the stem tube 200 is semicircular, so as to facilitate the operator to put in or take out the cross tube 100 and the stem tube 200 while achieving effective positioning of the cross tube 100 and the stem tube 200.

[0042] Preferably, the first limit block 21, the second limit block 22 and the third limit block 31 are made of wood or polyurethane to prevent the first limit block 21, the second limit block 22 and the third limit block 31 from making hard contact when restricting the handlebar tube 100, causing wear or damage to the outer surface of the handlebar tube 100, thereby affecting the user experience.
