Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator set outer frame technology, specifically to a coaxial direct-drive handle structure and a generator set. Background Technology
[0002] Existing generator sets typically have handles on their casings, allowing users to easily move the generator set. To save space and reduce packaging and transportation costs, the handles are usually designed to rotate relative to the casing, making it easy to store them on the panel when not in use.
[0003] In existing generator set handles, the two swing arms are typically connected to the frame independently. Due to factors such as assembly quality, the rotation axes of the two swing arms may not coincide. This causes the two swing arms to rotate asynchronously when the handle is turned to lift. Furthermore, this can lead to swing arm twisting, especially near the connection point with the frame. Over time, this can easily damage the swing arms and shorten the lifespan of the handle. Utility Model Content
[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a coaxial direct-drive handle structure and generator set, so that the two swing arms can rotate synchronously, avoid the twisting problem of the swing arms, and extend the service life of the handle.

[0006] Preferably, the device further includes two anti-detachment components disposed on the connecting shaft, each of the anti-detachment components corresponding to one of the swing arms, and the anti-detachment components are used to prevent the swing arm from detaching from the connecting sleeve.
[0007] Preferably, the swing arm is provided with a connecting block, the connecting sleeve is connected to the connecting block and has no relative rotation with the connecting block, and the anti-detachment component is provided on the side of the connecting block away from the connecting sleeve.

[0009] Preferably, it further includes two first gaskets, which are inserted through the screw and located on the side of the connecting block away from the connecting sleeve, and the anti-detachment component abuts the first gaskets against the connecting block.
[0010] Preferably, the connecting shaft includes a bushing and two shafts, the bushing connecting the two shafts respectively, and the two connecting sleeves respectively disposed on the two shafts.
[0011] Preferably, the bushing is fastened to the shaft body by bolts.

[0013] This utility model also provides a generator set, including the above-mentioned coaxial direct-drive handle structure.
[0014] The beneficial effects of this utility model are:
[0015] This utility model discloses a coaxial direct-drive handle structure and generator set.

[0035] like Figure 1-10 As shown, in one embodiment of this utility model, a coaxial direct-drive handle structure is provided, including a handle 10, two swing arms 20, a connecting shaft 30, and two connecting sleeves 40. The two swing arms 20 are respectively located at the left and right ends of the handle 10, and the handle 10 and the two swing arms 20 are integrally formed. Two mounting seats 60 for supporting the connecting shaft 30 are fixedly installed on the panel 50, and the connecting shaft 30 is rotatably fitted onto the two mounting seats 60. The connecting sleeves 40 are sleeved on the connecting shaft 30 and respectively close to both ends of the connecting shaft 30. The connecting sleeves 40 are connected to the corresponding swing arms 20, and the connecting sleeves 40 are connected to the connecting shaft 30 and the swing arms 20 without relative rotation.
[0036] This embodiment discloses a coaxial direct-drive handle structure. By designing two connecting sleeves 40 on the connecting shaft 30, each connecting sleeve 40 connects to a corresponding swing arm 20 on one side. This achieves a direct transmission connection between the two swing arms 20, ensuring that their rotation axes are always coaxial. Therefore, when the handle is rotated and lifted, the two swing arms 20 rotate synchronously at the same angle. This avoids the twisting problem caused by asynchronous rotation of the two swing arms 20 in conventional structures, extending the handle's service life and improving its stability during use.
[0037] In one embodiment, the coaxial direct-drive handle structure further includes two anti-detachment components 70 disposed on the connecting shaft 30, each anti-detachment component 70 corresponding to a swing arm 20, and the anti-detachment component 70 is used to prevent the swing arm 20 from detaching from the connecting sleeve 40. Since the connecting sleeve 40 is connected to the connecting shaft 30 and the swing arm 20 without relative rotation, the anti-detachment component 70 ensures that the swing arm 20 is always connected to the connecting sleeve 40.
[0038] Furthermore, the swing arm 20 is provided with a connecting block 80 made of metal, which is fixed to the side of the swing arm 20 facing the other swing arm 20 by bolts. The connecting sleeve 40 is connected to the connecting block 80 and does not rotate relative to the connecting block 80. The anti-detachment component 70 is provided on the side of the connecting block 80 away from the connecting sleeve 40. By designing the connecting block 80 on the swing arm 20, the structural strength at the connection between the swing arm 20 and the connecting sleeve 40, as well as the overall structural strength of the swing arm 20, can be improved, thereby avoiding the problem of deformation of the swing arm 20 during use of the handle.
[0039] Specifically, the connecting block 80 is provided with an anti-rotation hole 81, which is flat in shape. The connecting sleeve 40 is provided with an anti-rotation protrusion 41 that mates with the anti-rotation hole 81. The anti-rotation protrusion 41 and the connecting sleeve 40 are integrally formed. The anti-detachment component 70 is a nut. Both ends of the connecting shaft 30 are provided with screws 31. The screws 31 pass through the anti-rotation hole 81 and are threadedly connected to the anti-detachment component 70. When the anti-detachment component 70 is tightened onto the screws 31 and abuts against the connecting block 80, it can prevent the connecting block 80 from separating from the connecting sleeve 40. Of course, the diameter of the outer circle of the anti-detachment component 70 needs to be larger than the size of the anti-rotation hole 81 in order to achieve the function of the anti-detachment component 70.
[0040] In one embodiment, the coaxial direct-drive handle structure further includes two first washers 91. The first washers 91 are inserted through the screw 31 and located on the side of the connecting block 80 opposite to the connecting sleeve 40. The anti-detachment component 70 abuts the first washers 91 against the connecting block 80. The first washers 91 can increase the contact area between the anti-detachment component 70 and the connecting block 80, thus eliminating the need to select a larger anti-detachment component 70.
[0041] In one embodiment, the connecting shaft 30 includes a bushing 32 and two shafts 33. The bushing 32 is fixedly connected to the two shafts 33 by two bolts, and two connecting sleeves 40 are respectively disposed on the two shafts 33. By designing the connecting shaft 30 as a split structure, it is easier to assemble the shafts 33, connecting sleeves 40, swing arms 20, and mounting bases 60 on each side, thereby reducing the assembly difficulty while ensuring direct transmission connection between the two swing arms 20.
[0042] In one embodiment, the connecting sleeve 40 is provided with a limiting block 42, and the limiting block 42 is provided with a limiting groove 421. The mounting base 60 is provided with a limiting pin 61 that cooperates with the limiting groove 421. By designing the limiting block 42 to cooperate with the limiting pin 61 on the mounting base 60, the maximum rotation angle of the handle can be limited, thereby preventing the two swing arms 20 from rotating at the same angle at their extreme positions and preventing the swing arms 20 from twisting due to deviation in the direction of force when the operator pulls the handle. Of course, in order to prevent the limiting block 42 from directly abutting against the mounting base 60, a second washer 92 is provided on the shaft 33. The second washer 92 is located on the side of the limiting block 42 away from the first washer 91.
[0043] This embodiment also provides a generator set, including the aforementioned coaxial direct-drive handle structure. Because it employs the aforementioned coaxial direct-drive handle structure, it has the same working principle and technical effects as the coaxial direct-drive handle structure in the above embodiments, and will not be described again here.
[0044] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
