Description

Technical Field

[0001] The utility model relates to the technical field of locomotives, and in particular to an adjustable steering rod for locomotives. Background Art

[0002] The motorcycle steering bar is an important part of the motorcycle. It connects the handlebars and the body and is responsible for controlling the steering of the vehicle. The design and quality of the steering bar have a vital impact on the handling and safety of the motorcycle. The two ends of the steering bar are connected to the base and the vehicle's steering handle respectively, and the base is connected to the suspension components below.

[0003] In the prior art, the assembly of the faucet rod generally involves first drilling a hole on the faucet rod and then connecting it to the base. The drilled hole facilitates the connection of the faucet handle. In this process, since the faucet rod is first fixedly connected to the base, it is not calibrated during the installation process, and the threaded hole connected to the faucet handle is offset. When connecting it to the faucet handle again, the offset of the threaded hole makes it impossible to accurately install it. The faucet rod is fixed again, making it impossible to adjust it. Only a second hole can be drilled, which affects the installation efficiency. Utility Model Content

At this time, when connecting with the steering handle again, the offset of the threaded hole makes it impossible to accurately install it, and the steering rod is fixed, resulting in a situation where it cannot be adjusted and can only be drilled a second time, which affects the installation efficiency.

[0005] The utility model provides the following technical solutions: an adjustable steering rod for a locomotive, comprising a steering rod main body and a sub-rod, the end of the sub-rod is fixedly connected with an extension rod, the outer wall of the extension rod is provided with a first cover plate, the end of the steering rod main body is provided with an inner groove, the inner bottom end of the inner groove is provided with a bearing for assisting the extension rod to rotate, the outer wall of the extension rod is sleeved with an outer tube, and the outer wall of the outer tube is provided with a fixing component for limiting the sub-rod.

[0006] By adopting the above scheme, in order to be able to adjust the end of the faucet rod to adapt to the external faucet handle, when the end of the faucet rod needs to be adjusted, the sub-rod can be rotated so that the extension rod in the sub-rod can cooperate with the bearing and thus rotate. When it is about to be rotated to a suitable position, the sub-rod is driven to move downward, so that the extension rod also moves downward. After moving down to a certain position, the faucet rod continues to be rotated, so that the faucet rod can drive the fixing assembly to work, so as to achieve the purpose of limiting the sub-rod once by the fixing assembly and achieving fixation.

[0007] As a preferred embodiment of the above technical solution, the fixing component includes a first toothed disc rotatably connected to the inner wall of the inner groove, the outer wall of the outer tube is rotatably connected to the second cover plate, the end of the outer tube is fixedly connected to the second toothed disc that meshes with the first toothed disc for transmission, a plurality of large cams are fixedly connected at the interval between the second toothed disc and the second cover plate, a plurality of fixing rods are annularly rotatably connected at the interval between the second toothed disc and the second cover plate, and a plurality of small cams that squeeze the inner wall of the inner groove are fixedly connected to the outer wall of the fixing rod.

[0008] By adopting the above scheme, when the fixing assembly is used, the second toothed disc moves downward again under the drive of the auxiliary rod and cooperates with the first toothed disc. When the auxiliary rod rotates, it will drive the first toothed disc and the second toothed disc to engage and transmit, thereby driving the outer tube and the external large cam to rotate, and as the large cam rotates, the small cam is squeezed, and the protruding end of the small cam is able to squeeze the inner groove through the protruding end of the large cam, thereby achieving the purpose of the current auxiliary rod.

[0009] As a preferred embodiment of the above technical solution, the small cams are evenly arranged at the intervals of the protruding ends of the large cams, and the edge spacing between the small cams and the large cam is two centimeters.

[0010] By adopting the above solution, when the large cam rotates, the small cam can be squeezed into the inner groove with a small range of movement, so that the squeezing work on the inner groove can be achieved faster.

[0011] As a preferred embodiment of the above technical solution, a plurality of springs are annularly fixedly connected at the interval between the first cover plate and the second cover plate.

[0012] By adopting the above solution, through the use of the spring, when the auxiliary rod is moved downward, the second cover plate can be driven downward by the pressure of the spring, so that the second chuck and the first chuck can be meshed and transmitted.

[0013] As a preferred embodiment of the above technical solution, the extension rod is movably connected to the outer tube, and the extension rod is fixedly connected to the first gear disc and connected to the bearing.

[0014] By adopting the above scheme, the extension rod can be rotated under the drive of the auxiliary rod, and the use of the fixing component will not be affected during the rotation process. In addition, when the auxiliary rod drives the extension rod to move downward, it can penetrate the bearing without affecting the rotation effect, and the bearing can serve the purpose of limiting.

[0015] As a preferred embodiment of the above technical solution, a slot is provided at the inner bottom end of the inner groove below the bearing to facilitate the downward movement of the extension rod.

[0016] By adopting the above solution, the setting of the card slot can limit the position of the extension rod, thereby avoiding affecting the use effect due to excessive downward movement.

[0017] As a preferred embodiment of the above technical solution, the outer wall of the auxiliary rod is provided with a threaded hole for fixing the external faucet handle.

[0018] By adopting the above solution, the provision of the threaded hole can facilitate the connection of the external faucet handle to the secondary rod.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, an adjustment and fixing assembly is provided. During the working process, the auxiliary rod is driven to adjust the angle through the cooperation between the extension rod and the bearing to achieve the purpose of adapting to the faucet handle. When the adjustment is about to be completed, in order to limit the auxiliary rod, the provided fixing assembly can be rotated under the drive of the auxiliary rod, and the auxiliary rod is fixed once through the pressure generated by the rotation. Then, for the sake of stability, welding can be used for secondary fixing to achieve the purpose of tight connection. BRIEF DESCRIPTION OF THE DRAWINGS
