Description

Technical Field

[0001] This utility model relates to the field of chainsaw chain technology, specifically to a chainsaw chain with adjustable tension. Background Technology

[0002] A chainsaw is a handheld power tool mainly used for logging, garden trimming, furniture making, and decoration. It mainly consists of a small two-stroke gasoline engine, sprockets, chain, and guide plate. The small two-stroke gasoline engine drives the sprocket to rotate the sawing chain around the guide plate to perform cutting operations, achieving the purpose of cutting, pruning, and cutting timber, branches, and other materials.

[0003] After a certain period of use, existing chainsaw chains tend to loosen. Adjusting the chain tension often requires disassembling the device, increasing manual adjustment time. To address this issue, we propose a new chainsaw chain with adjustable tension, based on existing chainsaw chains. Utility Model Content

[0004] The purpose of this invention is to provide a chainsaw chain with adjustable tension to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable chainsaw chain, comprising a chainsaw body, a first handle and a second handle, wherein the first handle is installed on the left side of the chainsaw body, the second handle is installed on the top of the chainsaw body, and an adjustment device is installed inside the chainsaw body.

[0006] The adjusting device includes a storage tank, a guide plate, and a connecting plate. The storage tank is located inside the main body of the chainsaw, and the guide plate is located inside the storage tank. Connecting plates are installed on both sides of the left end of the guide plate. A plate body is installed at the middle position of the left end of the guide plate. A telescopic rod is installed on the left side of the plate body, and the telescopic rod is installed inside a telescopic cylinder. The left side of the telescopic cylinder is installed on the right side of a fixed plate. The fixed plate is installed on the inner wall of the main body of the chainsaw. Connecting columns are installed on both sides of the outer wall of the guide plate. The connecting columns pass through a sliding groove and connect to a connecting block. The sliding groove is installed inside the main body of the chainsaw, and a groove is provided on the left side of the sliding groove. A control button is installed inside the sliding groove. A drive wheel is installed on the left side of the fixed plate. One side of the drive wheel is connected to the inner wall of the main body of the chainsaw via a bearing. The other side of the connecting plate is connected to the main body of the chainsaw. A chain is installed on the outer wall of the drive wheel and the outer wall of the guide plate.

[0007] Preferably, the gasoline saw body is fixedly connected to the first handle and the second handle, and the gasoline saw body and the storage tank are integrated.

[0008] Preferably, the interior of the storage tank is correspondingly arranged with respect to the guide plate, and the guide plate is fixedly connected to the connecting plate, the plate body and the connecting column.

[0009] Preferably, the plate body and the telescopic rod are fixedly connected, and the telescopic rod and the telescopic cylinder are slidably connected.

[0010] Preferably, the telescopic cylinder and the fixed plate are fixedly connected, and the motor on the outside of the telescopic cylinder is electrically connected to the control button.

[0011] Preferably, the control button is correspondingly positioned to the inner side of the groove, and the groove is integrally formed with the gasoline saw body.

[0012] Preferably, the connecting column and the connecting block are fixedly connected, and the connecting column and the sliding groove are slidably connected.

[0013] Preferably, the slide groove and the gasoline saw body are integrated, and the gasoline saw body and the drive wheel are connected by a drive mechanism.

[0014] Preferably, the chains are all correspondingly arranged between the outer side of the drive wheel, the outer wall of the guide plate, and the outer wall of the connecting plate.

[0015] Preferably, the transmission wheel and the bearing are rotatably connected.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up a storage tank, guide plate, and connecting plate, starting the chainsaw body drives the drive wheel to rotate inside the bearing. The drive wheel drives the chain on the outside of the guide plate. When the device has been used for a long time, the chain may become loose. The user presses the control button to start the motor on the outside of the telescopic cylinder. The motor on the outside of the telescopic cylinder drives the telescopic rod to slide inside the telescopic cylinder. The telescopic rod drives the guide plate connected to the plate to slide inside the storage tank. The guide plate drives the connecting column to slide inside the slide groove, so that the guide plate slides out of the device, making it easier to adjust the chain looseness. This also reduces the time spent manually adjusting the chain looseness and improves the maintenance efficiency of the device. Attached Figure Description
