Description

Technical Field

[0001] The utility model relates to the technical field of electric cutting tools, in particular to a novel electric chain saw. Background Art

[0002] In the traditional logging industry, manual saw blades are used for logging operations. Later, people invented electric saws to replace manual saw blades, saving a lot of time and labor. Electric saws are tools frequently used by people in the logging industry in modern times. The current electric chain saw is a woodworking power tool that uses a rotating chain saw blade for sawing. It is suitable for logging in forest areas, material selection in wood factories, etc., which greatly saves the time and manpower spent on cutting materials.

[0003] At present, when using an electric chain saw, the operator's hand-held position is in a straight line with the guide bar containing the saw chain. During the sawing process, the operator is required to apply a large force, which causes certain inconveniences in use; the working head and the base are fixed by bolts, and installation and disassembly are time-consuming and labor-intensive, and extremely inconvenient; moreover, when the saw chain rotates around the outer edge of the guide bar for a long time, once it is worn, it is easy to become loose between the guide bar, thereby affecting the sawing effect. The chain tightening effect can only be achieved by removing a small section of the chain link on the saw chain, which is time-consuming and labor-intensive, and increases labor intensity.

[0004] Therefore, a novel electric chain saw is proposed to solve the current shortcomings. Utility Model Content

In this embodiment, the structure of the base 1 is a rectangular structure, which can fix and support the drive motor 2 and the chain saw part.

[0041] The drive motor 2 is fixedly arranged at one end of the base 1. In the present 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. When in use, the drive motor 2 is connected to the chain saw part by an output shaft.

[0042] The chain saw portion includes a guide plate 3 and a saw chain 4. The output shaft of the drive motor 2 is connected to a sleeve 5. Specifically, the sleeve 5 is fixedly connected to the output shaft of the drive motor 2 by a key. Through the connection between the sleeve 5 and the drive motor 2, the sleeve 5 can be driven to rotate by the drive motor 1. During implementation, the sleeve 5 is connected to the bearing 6 and the sprocket 8, so that the saw chain 4 can work normally on the guide plate 3 while the bearing 6 rotates along the sleeve 5.

[0043] A bearing 6 is sleeved in the middle of the shaft sleeve 5. Specifically, there are two bearings 6 and they are arranged along the axial direction of the output shaft of the driving motor 2. A certain distance is set between the two bearings 6.

[0044] In this embodiment, the bearing 6 is connected to the rotating frame 7 , so that the rotating frame 7 can rotate around the axis of the driving motor 2 , thereby enabling the guide plate 3 to rotate around the output shaft of the driving motor 2 .

[0045] At the same time, by disposing two bearings 6 at a certain distance, the stability of the rotation of the rotating frame 7 around the output shaft of the driving motor 2 can be ensured, thereby ensuring the stability of the overall structure in use.

[0046] A rotating frame 7 is sleeved on the bearing 6. During implementation, the rotating frame 7 is connected to the guide plate 3 and the handle 11. The rotating frame 7 rotates around the axis of the output shaft of the drive motor 2, driving the guide plate 3 and the saw chain 4 to rotate around the axis of the output shaft of the drive motor 2, thereby achieving cutting of the workpiece to be cut.

[0048] During implementation, the rotating ring 71 is sleeved on the bearing 6, and the rotating ring 71 can be rotated around the output shaft of the driving motor 2 through the bearing 6, thereby driving the chain saw part to rotate around the output shaft of the driving motor 2 to achieve cutting of the workpiece to be cut.

[0049] A sprocket 8 is connected to the front end of the output shaft of the driving motor 2. 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 to be cut.

[0050] The guide plate 3 is connected to the rotating frame 7. In this embodiment, the guide plate 3 is movably connected to the connecting plate 72. During implementation, the guide plate 3 can move along the extending direction of the connecting plate 72.

[0054] Specifically, the adjustment mechanism includes a fixing plate 13 and an adjusting bolt 14 . The fixing plate 13 is fixedly connected to the guide plate 3 . The end of the fixing stud 10 extends to the outside of the fixing plate 13 . The fixing plate 13 is threadedly connected with an adjusting bolt 14 that abuts against the fixing stud 10 .

[0055] In this embodiment, the fixing stud 10 is threadedly connected to the connecting plate 72, and the fixing plate 13, the guide plate 3 and the connecting plate 72 can be fixed by tightening the fixing stud 10. The adjusting bolt 14 is arranged parallel to the fixing plate 13, and the end of the adjusting bolt 14 abuts against the fixing stud 10 through the adjusting bolt 14 being threadedly connected to the fixing plate 13.

[0056] During implementation, when the saw chain 4 is 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.

[0057] The saw chain 4 is rotatably mounted between the sprocket wheel 8 and the guide plate 3 . In practice, the saw chain 4 can be driven on the guide plate 3 by the arrangement of the sprocket wheel 8 .

[0063] It also includes a lubrication device, which is arranged 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;

[0064] 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 arranged on the bracket 19. The regulating valve 18 is connected to the lubrication bottle 17. The flow rate of the lubricating oil can be controlled by setting the regulating valve 18.

[0065] The fixing plate 13 is provided with a connector 20 , and a hole 23 communicating with the connector 20 is provided at the joint of the guide plate 3 and the saw chain 4 . The regulating valve 18 is connected to the connector 20 through a hose.

[0066] During implementation, 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 the connector 20, thereby lubricating the saw chain 4 passing through the groove 21. The saw chain 4 rotates on the guide plate 3 and the sprocket 8, thereby achieving lubrication of the entire part.

[0067] It also includes a guard plate 16, which is arranged along the guide plate 3 and one end of which is rotatably connected to the connecting plate 15.

[0068] The connecting plate 15 is provided with a tension spring 21 connected to the base 1. The base 1 is provided with limit plates 22 cooperating with the rotating frame 7 on both sides of the rotating frame 7.

[0069] In a specific implementation, the limiting plate 22 and the tension spring 21 at the rear side of the rotating frame 7 can maintain a certain angle between the chain saw and the base 1. The limiting plate 22 at the front side of the rotating frame 7 can limit the chain saw when it moves downward, so as to prevent the chain saw from moving too low and contacting the ground or the base 1, thereby causing damage to the chain saw.
