Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, and in particular to a folding handle structure for a small generator set. Background Technology
[0002] Small generator sets are typically equipped with handles for easy transport. Handles include fixed handles and folding handles. When using a folding handle, the handle needs to be frequently opened or folded and locked during equipment use.
[0003] In existing folding handles, the pivot point is usually set with a simple flat pad. After the handle is manufactured and assembled, its friction is difficult to adjust. If the assembly is too tight, the friction is too high and it is difficult to operate. If the assembly is too loose, the friction is too low and it is too loose, which is not conducive to the opening or folding operation of the folding handle. Further improvement is needed. Utility Model Content
[0004] To address the aforementioned issues, the present invention aims to provide a folding handle structure for a small generator set. By improving the structure at the handle's pivot point, it ensures that the frictional force remains balanced during the opening or folding process of the assembled handle, preventing the frictional force from becoming too large or too small, thus facilitating operation and use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A folding handle structure for a small generator set includes a handle body and a rotating shaft assembly. Each rotating shaft assembly includes a fixed base, a rotating shaft, an elastic component, a fixing bolt, and a locking nut. The fixed base has a mounting hole, and the fixing bolt passes through the mounting hole. The locking nut fixes the rotating shaft and the elastic component to one end of the fixed base. The other end of the fixed base is fixed to the generator set panel housing. The rotating shaft can rotate relative to the mounting hole. A rotating swing arm is sleeved on the rotating shaft, and the rotating swing arm is fixedly connected to the handle body.
[0006] Furthermore, the elastic component includes a first flat pad, a first spring pad, a second spring pad, and a second flat pad arranged and stacked in sequence.
[0007] Furthermore, the first and second spring pads are butterfly spring sheets, and the first and second spring pads are arranged facing each other.
[0008] Furthermore, a support tube is fitted into the central hole of the rotating shaft.
[0009] Furthermore, the fixing bolt is provided with a locking flat washer and an adjusting spring washer, one end of the support tube abuts against the fixing seat, and the other end of the support tube abuts against the locking flat washer.
[0010] Furthermore, the apertures of the first flat pad, the first spring pad, the second spring pad, and the second flat pad are larger than the outer diameter of the support tube.
[0011] Furthermore, a pivot limit baffle is provided between the pivot shaft and the elastic component, a limit hook is provided on the pivot limit baffle, and a stop pin is provided on the fixed base to limit the rotation position of the limit hook.
[0012] Furthermore, the rotating shaft is provided with a stepped flat shaft, and the rotating swing arm is provided with a flat shaft hole that matches the stepped flat shaft.
[0013] This utility model has the following beneficial effects: 1. This utility model sets an elastic component in the rotating shaft assembly, and sets a butterfly spring sheet arranged face to face in the elastic component. By controlling the deformation of the butterfly spring sheet during production and assembly, it ensures that the friction force of the handle after production and assembly remains balanced during the opening or folding process. The friction force is not too large or too small, which facilitates operation and use.
[0014] 2. The rotating shaft of this utility model has a support tube in the center hole. After the fixing bolt is tightened, the length of the support tube is used to control the deformation of the butterfly spring. When the rotating shaft rotates, the butterfly springs arranged face to face rotate by friction, which can keep the friction force balanced during the rotation. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See Figure 1-7 As shown, a folding handle structure for a small generator set includes a handle body 1 and a rotating shaft assembly 2. Each rotating shaft assembly 2 includes a fixed base 21, a rotating shaft 22, an elastic component 23, a fixing bolt 24, and a locking nut 25. The fixed base 21 is provided with a mounting shaft hole 211. The fixing bolt 24 passes through the mounting hole and the locking nut 25 fixes the rotating shaft 22 and the elastic component 23 to one end of the fixed base 21. The other end of the fixed base 21 is fixed to the generator set panel housing. The rotating shaft 22 can rotate relative to the mounting shaft hole 211. A rotating swing arm 26 is sleeved on the rotating shaft 22. The rotating swing arm 26 is fixedly connected to the handle body 1. The rotating shaft 22 is provided with a stepped flat shaft 221. The rotating swing arm 26 is provided with a flat shaft hole 261 that matches the stepped flat shaft 221. The rotating swing arm 26 rotates together with the rotating shaft 22. The elastic component 23 includes a first flat pad 231, a first spring pad 232, a second spring pad 233, and a second flat pad 234 arranged and stacked in sequence. The first spring pad 232 and the second spring pad 233 are butterfly spring sheets, and the first spring pad 232 and the second spring pad 233 are arranged facing each other.
[0018] A support tube 27 is fitted into the central hole of the rotating shaft 22. The fixing bolt 24 is equipped with a locking flat washer 28 and an adjusting spring washer 29. One end of the support tube 27 abuts against the fixing seat 21, and the other end of the support tube 27 abuts against the locking flat washer 28. The diameters of the holes in the first flat washer 231, the first spring washer 232, the second spring washer 233, and the second flat washer 234 are larger than the outer diameter of the support tube 27.
