Description

Technical Field

[0001] This utility model relates to the field of starter technology, and in particular to a speed-increasing hand-operated disc device. Background Technology

[0002] The starter in the prior art is a device that releases the mechanical energy stored in a wound spring through a mechanism, converting it into kinetic energy, thereby starting a diesel or gasoline engine.

[0003] In actual use, the pull cord is pulled to rotate the pull plate, which causes the torsion spring on the outer periphery of the pull plate to store force. When the pull plate is released, the machine can be started. In order to ensure that the pull plate is fully charged, the pull cord needs to be pulled to a sufficient length each time. This operation is relatively laborious and inconvenient. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a speed-increasing hand-operated cable device that significantly shortens the cable travel during use, making it more convenient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a speed-increasing hand-operated disc device, having a housing, a disc and its coil spring inside the housing, a speed-increasing gear set on the disc, the speed-increasing gear set including a sun gear, planetary gears and an external gear ring, the output shaft of the disc being disposed on the sun gear, the planetary gears being disposed on the disc along the outer periphery of the sun gear and meshing with the sun gear and the external gear ring respectively.

[0006] In the above technical solution, the pull plate is provided with a plurality of gear fixing posts, and each gear fixing post is provided with a planetary gear, which is fixedly mounted on the gear fixing post.

[0007] In the above technical solution, the characteristic is that: a gear frame is further provided between the pull plate and the gear fixing column, and the planetary gear is mounted on the gear frame through the gear fixing column.

[0008] In the above technical solution, the middle part of the pull plate is provided with a coupling plug, and the middle part of the sun gear is fixedly connected to the coupling plug.

[0009] In the above technical solution, the speed-increasing gear set also includes a gear compartment cover, and the external gear ring is disposed on the inner side of the gear compartment cover.

[0010] In the above technical solution, the outer periphery of the gear compartment cover is provided with a plurality of compartment cover bolts, which are fixedly connected to the housing by the compartment cover bolts.

[0011] In the above technical solution, the housing also includes a coil spring, which is disposed on the other side of the pull plate relative to the speed-increasing gear set and is used for the pull plate to reset.

[0012] In summary, the advantages of this utility model over traditional technologies are as follows: This utility model improves the starter pull plate device by adding a planetary gear structure to the original transmission structure of the pull plate device. The output speed is amplified by the planetary gear set, which can significantly shorten the cable pull stroke under normal starting conditions, making it more convenient for users.
