Description

Technical Field

[0001] This application belongs to the field of electric cutting tool technology, and particularly relates to an electric chainsaw. Background Technology

[0002] In the traditional logging industry, manual saw blades were used for logging operations. Later, the invention of the electric chainsaw replaced manual saw blades, saving a lot of time and labor. The electric chainsaw is a tool frequently used in the logging industry in modern times. The current electric chainsaw is a woodworking power tool that uses a rotating chain saw blade for sawing. It is suitable for logging in forest areas and timber selection in timber mills, greatly saving the time and manpower spent on cutting materials.

[0003] Currently, when using an electric chainsaw, the operator's hand position is in a straight line with the guide plate containing the saw chain. During sawing, the operator needs to apply considerable force, which is somewhat inconvenient. The working head and the base are fixed by bolts, and installation and disassembly are time-consuming and labor-intensive, making them extremely inconvenient. Moreover, when the saw chain rotates around the outer edge of the guide plate for a long time, wear can easily occur, causing loosening between the chain and the guide plate, thus affecting the sawing effect. The only way to tighten the chain is to remove a small link, which is also time-consuming and labor-intensive, requiring a high level of physical exertion.

[0047] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0048] Please see Figures 1 to 10 This application provides an electric chainsaw, which includes a base, a drive motor, a chainsaw section, a lubrication device, and a guard plate. The following is a detailed description:

[0049] The base 1 has a cuboid structure, which serves to fix and support the drive motor 2 and the chainsaw section. In other embodiments, the base may also have other shapes.

[0050] The drive motor 2 is fixedly mounted on one end of the base 1. In this embodiment, the drive motor 2 is fixedly connected to the base 1 by bolts. Specifically, the drive motor 1 is arranged along the width direction of the base 1. In use, the drive motor 2 is connected to the chainsaw part through the output shaft.

[0051] The chainsaw unit includes a guide plate 3 and a saw chain 4. The output shaft of the drive motor 2 is connected to a bushing 5. Specifically, the bushing 5 is fixedly connected to the output shaft of the drive motor 2 by a key. Through the connection between the bushing 5 and the drive motor 2, the drive motor 1 can drive the rotation of the bushing 5. In practice, the bushing 5 is connected to the bearing 6 and the sprocket 8, so that while the bearing 6 rotates along the bushing 5, the saw chain 4 can work normally on the guide plate 3.

[0052] The bushing 5 is fitted with a bearing 6 in the middle. Specifically, there are two bearings 6, which are arranged along the axial direction of the output shaft of the drive motor 2, and there is a certain distance between the two bearings 6.

[0053] In this embodiment, the bearing 6 is connected to the rotating frame 7, enabling the rotating frame 7 to rotate around the axis of the drive motor 2, thereby allowing the guide plate 3 to rotate around the output shaft of the drive motor 2. Simultaneously, the arrangement of two bearings 6 spaced a certain distance apart ensures the stability of the rotating frame 7's rotation around the output shaft of the drive motor 2, thus guaranteeing the overall structural stability.

[0054] A rotating frame 7 is fitted onto the bearing 6. In practice, the rotating frame 7 connects with the guide plate 3 and the handle 11. By rotating the rotating frame 7 around the output shaft axis of the drive motor 2, the guide plate 3 and the saw chain 4 part rotate around the output shaft axis of the drive motor 2, thereby achieving the cutting of the workpiece.

[0055] Specifically, the rotating frame 7 includes a rotating ring 71 and a connecting plate 72 connected to the rotating ring 71. The rotating ring 71 is sleeved on the bearing 6. The number of fixing studs 10 is two and they are arranged along the length direction of the connecting plate 72.

[0056] In practice, the rotating ring 71 is sleeved on the bearing 6. The rotating ring 71 can rotate around the output shaft of the drive motor 2 through the bearing 6, thereby driving the chainsaw to rotate around the output shaft of the drive motor 2, so as to cut the workpiece to be cut.

[0057] The output shaft of the drive motor 2 is connected to a sprocket 8 at its front end. In a specific implementation, the sprocket 8 is connected to the saw chain 4. At the same time, through the setting of the guide plate 3, the rotation of the sprocket 8 can realize the rotation of the saw chain 4 on the guide plate 3, thereby realizing the cutting of the workpiece.

[0058] The guide plate 3 is connected to the rotating frame 7. In this embodiment, the guide plate 3 and the connecting plate 72 are movably connected. During implementation, the guide plate 3 can move along the extension direction of the connecting plate 72.

[0059] The guide plate 3 is provided with an adjustment groove 9. Specifically, the adjustment groove 9 is located at one end of the guide plate 3 and is set along the length direction of the guide plate 3. In this embodiment, the adjustment groove 9 is a long strip structure.

[0060] The rotating frame 7 is provided with a fixing stud 10 passing through the adjustment groove 9. Specifically, the fixing stud 10 is set on the connecting plate 72. In this embodiment, there are two fixing studs 10 and they are set along the length direction of the connecting plate 72. There is a certain distance between the two fixing studs 10. In implementation, the fixing stud 10 passes through the adjustment groove 9, which allows the guide plate 3 to move along the length direction of the connecting plate 72.

[0061] The guide plate 3 is provided with an adjustment mechanism that cooperates with the fixing stud 10 to move the guide plate 3 back and forth along the adjustment groove 9. In practice, the guide plate 3 can move on the connecting plate 72 through the cooperation of the adjustment mechanism and the fixing stud 10, thereby adjusting the tension of the saw chain 4.

[0062] Specifically, the adjustment mechanism includes a fixed plate 13 and an adjusting bolt 14. The fixed plate 13 is fixedly connected to the guide plate 3. The end of the fixing stud 10 extends to the outside of the fixed plate 13. The adjusting bolt 14, which abuts against the fixing stud 10, is threaded onto the fixed plate 13.

[0063] In this embodiment, the fixing stud 10 is threadedly connected to the connecting plate 72. By tightening the fixing stud 10, the fixing plate 13, the guide plate 3, and the connecting plate 72 can be fixed. The adjusting bolt 14 is arranged parallel to the fixing plate 13 and is threadedly connected to the fixing plate 13. The end of the adjusting bolt 14 abuts against the fixing stud 10.

[0064] During implementation, when the saw chain 4 becomes loose, first loosen the fixing stud 10, and then rotate the adjusting bolt 14. Since the adjusting bolt 14 abuts against the fixing stud 10, the relative position between the guide plate 3 and the connecting plate 72 can be adjusted. After the tightness of the saw chain 4 is adjusted, tighten the fixing stud 10 to fix the guide plate 3 and the connecting plate 72.

[0065] The saw chain 4 is rotatably mounted between the sprocket 8 and the guide plate 3. In practice, the sprocket 8 enables the saw chain 4 to be driven on the guide plate 3.

[0066] The rotating frame 7 is connected to a handle 11 located on the upper side of the chainsaw section. Specifically, the structure of the handle 11 can be set according to the actual situation. In this embodiment, the handle 11 is an arc-shaped structure. In implementation, the chainsaw section can be rotated through the handle 11, thereby realizing the cutting operation of the workpiece to be cut.

[0067] In one embodiment, the rotating ring 71 is provided with a connecting plate 15, and the handle 11 is rotatably connected to the connecting plate 15. In another embodiment, the handle 11 and the connecting plate 15 may be fixedly connected.

[0068] The handle 11 is equipped with a switch 12 that is electrically connected to the drive motor 2. The switch 12 allows for easy start and stop of the drive motor 2, thereby enabling start and stop of the chainsaw section. This improves the operational safety of the electric chainsaw while controlling the cutting operation of the workpiece.

[0069] In this embodiment, the lubrication device is installed on the base 1 and is used for lubricating the saw chain 4 and the guide plate 3 to ensure the performance of the saw chain 4.

[0070] Specifically, the lubrication device includes a lubrication bottle 17 and a regulating valve 18. A bracket 19 is provided on the base 1, the lubrication bottle 17 is set on the bracket 19, and the regulating valve 18 is connected to the lubrication bottle 17. The flow rate of lubricating oil can be controlled by the regulating valve 18.

[0071] The fixed plate 13 is provided with a connector 20, and the guide plate 3 and the saw chain 4 are provided with a slot 23 that communicates with the connector 20. The regulating valve 18 is connected to the connector 20 through a flexible hose.

[0072] In practice, the lubrication bottle 17 is filled with lubricating oil, and the flow rate of the lubricating oil is controlled by the regulating valve 18. The lubricating oil flows to the groove 21 through the hose and connector 20, thereby lubricating the saw chain 4 passing through the groove 21. The entire saw chain 4 is lubricated by rotating on the guide plate 3 and the sprocket 8.

[0073] In this embodiment, the guard plate 16 is located on the side of the guide plate 3 facing the handle 11, and partially covers the guide plate 3 and the corresponding saw chain 4. The guard plate 16 is rotatably connected to the end of the guide plate 3 away from the sprocket 8. Figure 2 and Figure 3 As shown, the guard plate 16 can rotate along the portion connected to the guide plate 3, so that the guard plate 16 moves away from or closer to the guide plate 3, thereby exposing or covering the guide plate 3 and the chain on the guide plate 3, facilitating chain adjustment, and improving safety during operation. Specifically, the guard plate 16 can be rotatably connected to the guide plate 3 via a rotating shaft.

[0074] Furthermore, the guide plate 3 is provided with a limiting baffle 31, which extends out of the guide plate 3 and is used to abut against the guard plate 16. The limiting baffle 31 can prevent the guard plate 16 from directly contacting the chain on the guide plate 3 and prevent the guard plate 16 from interfering with the rotation of the chain.

[0075] In this embodiment, the guard plate 16 and the handle 11 are not on the same plane. When the guard plate 16 rotates, it can cross the handle 11 without interfering with each other, which increases the opening and closing range of the guard plate 16 and facilitates operation.

[0076] The connecting plate 15 is provided with a tension spring 21 that connects to the base 1. The base 1 is provided with limiting plates 22 that cooperate with the rotating frame 7 on both sides.

[0077] In practical implementation, the limiting plate 22 and tension spring 21 located on the rear side of the rotating frame 7 can maintain a certain angle between the chainsaw and the base 1. The limiting plate 22 located on the front side of the rotating frame 7 can limit the chainsaw when it moves downward, preventing the chainsaw from moving too low and causing it to touch the ground or the base 1, which would damage the chainsaw.

[0078] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. The directional terms "inner" and "outer" refer to the inside or outside relative to the outline of the component itself. For example, if a device in the drawings is inverted, a device described as "above" or "on top of other devices or structures" will later be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0079] It should also be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this application refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0080] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0081] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application.
