Description

Technical Field

[0001] This invention relates to the field of electric chainsaw technology, specifically to an electric chainsaw with a chain adjustment mechanism. Background Technology

[0002] In the field of power tools, electric chainsaws, as a highly efficient cutting tool, are widely used in wood processing, forestry logging, and other scenarios. Their core function is to cut by using a motor to drive a chain that moves at high speed along the saw blade. The stability and tension of the chain directly affect cutting efficiency, safety, and equipment lifespan; therefore, electric chainsaws with chain adjustment functions are crucial for improving tool performance. These devices need to achieve chain anti-slip, automatic tensioning, and stable lubrication to meet the demands of long-term, high-intensity operation, making them essential equipment for ensuring the continuity and reliability of cutting operations.

[0003] Existing electric chainsaws have significant limitations in chain adjustment and stability. Regarding chain securing, traditional equipment lacks effective limiting structures, making the chain prone to loosening due to stretching after prolonged use, and even detaching from the saw blade, posing a safety hazard, especially at high speeds. For tension adjustment, traditional equipment relies heavily on manual adjustment, failing to automatically compensate for chain wear, resulting in unstable chain-saw blade connection and affecting cutting accuracy and efficiency. Insufficient saw blade securing is also problematic; a single securing method is insufficient to withstand vibrations during cutting, easily causing saw blade wobbling and further exacerbating chain wear and loosening. Furthermore, traditional lubrication methods often involve direct application of lubricant, leading to uneven distribution and easy dripping and waste. Additionally, cutting debris can easily enter the transmission components, causing chain jamming and restricting the electric chainsaw's operational stability and lifespan. Summary of the Invention

[0004] The present invention provides an electric chainsaw with a chain adjustment mechanism, which solves the problems mentioned in the background art above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric chainsaw with a chain adjustment mechanism, comprising a housing, a battery fixedly connected to the bottom of the housing, a switch provided at the tail of the housing, and a cover plate fixedly fitted to the outer surface of the housing; further comprising: a chainsaw mechanism fixedly installed inside the housing; and a stabilizing mechanism fixedly installed on the chainsaw mechanism; wherein the chainsaw mechanism includes a motor fixedly installed on the outer surface of the housing, a drive shaft rotatably connected to the output end of the motor, the end of the drive shaft away from the motor being located inside the housing, a drive disc fixedly connected to the outer surface of the drive shaft, a slot provided on the side surface of the drive disc, a saw blade provided inside the housing, a chain slidably mounted on the saw blade, the end of the chain away from the saw blade being rotatably connected to the drive disc through the slot, and a blade head fixedly mounted on the chain.

[0006] According to one embodiment of the present invention, a connecting piece is fixedly connected to the chain, the connecting piece is disposed on the inner side of the chain, and a sliding groove is formed on the outer surface of the saw plate, wherein the connecting piece is respectively disposed in the sliding groove and the slot on the drive plate.

[0007] According to one embodiment of the present invention, a retaining strip is fixedly connected to the inner surface of the groove of the saw blade, and limiting grooves are symmetrically opened on the outer surfaces of both sides of the connecting piece. The upper and lower sides of the limiting groove are set as arc surfaces, wherein the limiting groove and the retaining strip are engaged with each other.

[0008] According to one embodiment of the present invention, a fixing groove is formed through the outer surface of the saw blade near the drive disc, wherein the fixing strip is strip-shaped, and a fixing rod is slidably arranged inside the fixing groove. Two fixing rods are arranged parallel to each other, and the two ends of the two fixing rods are respectively fixedly connected to the inner surfaces of the two sides of the outer shell.

[0009] According to one embodiment of the present invention, a fixing plate is fixedly connected to the inner surfaces of both sides of the outer shell. The fixing plate is L-shaped, and a limiting plate is elastically slidably inserted into the fixing plate. A pressing plate is fixedly connected to the end of the limiting plate away from the fixing plate. The pressing plate and the fixing plate are arranged in the same shape. The outer surface of the pressing plate presses against the outer surface of the saw blade. The pressing plate and the fixing plate are in a highly elastic state through the limiting plate, and the two ends of the pressing plate are slidably connected to the inner surface of the outer shell.

[0010] According to one embodiment of the present invention, the stabilizing mechanism includes a stabilizing groove, which is symmetrically opened on both sides of the fixing groove. A stabilizing plate is slidably disposed inside the stabilizing groove. The two ends of the stabilizing plate are fixedly connected to the inner surface of the outer shell. The upper and lower surfaces of the stabilizing plate are symmetrically hinged with locking plates by torsion springs, wherein the maximum rotation angle of the locking plates is forty-five degrees.

[0011] According to one embodiment of the present invention, auxiliary grooves are symmetrically formed on both sides of the saw blade near the drive disc, and a sealing cover is slidably inserted into the auxiliary groove. The outer surface of the sealing cover is fixedly embedded in the inner surfaces of both sides of the outer shell, wherein the sealing cover fastens the stabilizing plate and the snap-fit ​​plate.

[0012] According to one embodiment of the present invention, a filling groove is provided inside the saw blade, and a compression bladder is fixedly installed in the filling groove. A liquid inlet is provided on the side surface of the saw blade, wherein there are two liquid inlets, and the liquid inlets communicate with the internal cavity of the compression bladder.

[0013] According to one embodiment of the present invention, a pressure strip is fixedly connected to the bottom of the compression bladder, the pressure strip is elastically slidably connected to the bottom of the filling groove, and a toggle block is fixedly connected to the bottom surface of the pressure strip. The bottom of the toggle block is disposed in the groove of the saw blade. A sponge strip is fixedly embedded inside the locking strip, and the internal cavity of the locking strip communicates with the internal cavity of the compression bladder. When the electric chainsaw is needed, the handheld outer casing can be moved to a designated position, and the motor can be started by controlling the switch on the outer casing. After the motor starts, it will drive the drive disc to start rotating through the drive shaft, thereby controlling the chain connected to it to start moving through the rotation of the drive disc. Cutting is achieved by the fast-moving chain in conjunction with the blade. During the movement of the chain, the connecting piece on the inner side of the chain is in the groove of the saw blade. The connecting piece limits the chain, so that it always moves along the edge of the saw blade, thereby improving the stability of the electric chainsaw.

[0014] This invention provides an electric chainsaw with a chain adjustment mechanism. It has the following advantages: (i) This electric chainsaw with a chain adjustment mechanism, by setting a locking strip in the slide groove of the saw plate and opening limiting grooves on both sides of the chain connecting plate, can make the limiting groove on the connecting plate engage with the locking strip in the slide groove when the chain moves, thereby limiting the connection plate and the locking strip in the slide groove to a relative position, ensuring that the chain always stays close to the edge of the saw plate when moving, avoiding the problem of the chain being stretched and falling off the saw plate during long-term operation, greatly improving the working stability of this electric chainsaw, especially maintaining stability during long-term operation.

[0015] (II) In this electric chainsaw with a chain adjustment mechanism, the inner end of the saw blade is pressed against the outer surface of the pressing plate. During installation, the inner end of the saw blade is under strong elastic pressure between the pressing plate and the limiting plate, and is basically fixed by the fixing groove and fixing rod. Simultaneously, stabilizing grooves are provided on both sides of the fixing groove, and stabilizing plates are slidably installed within the stabilizing grooves. This multi-level fixing effect, achieved through the stabilizing plate, fixing rod, and pressing plate, significantly improves the stability of the saw blade during operation. Furthermore, the saw blade is under elastic pressure with the fixing plate, ensuring that the outer end of the saw blade is always in contact with the chain. There is an expansion and compression force, which keeps the chain in a stretched state during operation, preventing the chain from loosening and the connection between the chain and the saw blade from becoming unstable after long-term use. At the same time, this electric chainsaw has an automatic adjustment function to automatically maintain the working stability of the chain. Because the two sides of the stabilizing plate are hinged with locking plates by torsion springs, the saw blade cannot move to one side of the outer shell after the saw blade is installed. It only moves outward to lock the chain when it is loose, which further greatly improves the stability of the saw blade during operation.

[0016] (III) This electric chainsaw with a chain adjustment mechanism can further limit the movement stability of the saw blade through the auxiliary groove and sealing cover, so that the saw blade can only move laterally outward, thereby improving working stability. At the same time, the sealing cover can also relatively seal the fixed groove and the stabilizing groove, preventing the debris generated during cutting from entering the fixed groove and the stabilizing groove and affecting working stability. Before the electric chainsaw starts working, lubricating oil is injected into the compression bladder in the filling groove through the liquid inlet. When the chain moves, it will squeeze the actuating block through its connecting plate, thereby causing the actuating block to move upward intermittently, and then start to push the pressure bar to move upward in the filling groove to squeeze the compression bladder. The compression process delivers lubricating oil from the squeeze bladder to the sponge strip in the clip. The lubricating oil in the sponge strip lubricates the limiting groove at the connecting plate, thereby significantly improving the chain's working stability and preventing the chain from jamming during operation. Because the squeeze bladder is intermittently compressed, it is subjected to intermittent high and negative pressure states inside. Under high pressure, the lubricating oil is delivered to the sponge strip, and under negative pressure, the lubricating oil is absorbed from the sponge strip in the reverse direction. This significantly improves the uniformity of lubrication while avoiding the problem of lubricating oil waste. It avoids the problem of uneven lubrication and oil dripping caused by the direct application of lubricating oil to the chain in existing lubrication structures. Attached Figure Description

[0020] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: an electric chainsaw with a chain 56 adjustment mechanism, including a housing 1, a battery 2 fixedly connected to the bottom of the housing 1, a switch 3 provided at the tail of the housing 1, and a cover plate 4 fixedly fitted onto the outer surface of the housing 1, and further including: Chainsaw mechanism 5 is fixedly installed inside the outer casing 1; Stabilizing mechanism 6 is fixedly installed on chainsaw mechanism 5; The chainsaw mechanism 5 includes a motor 51, which is fixedly installed on the outer surface of the housing 1.

[0021] A connecting piece 58 is fixedly connected to the chain 56. The connecting piece 58 is located on the inner side of the chain 56. A groove 59 is provided on the outer surface of the saw blade 55. The connecting piece 58 is respectively located in the groove 59 and the slot 54 on the drive disc 53.

[0022] A retaining strip 510 is fixedly connected to the inner surface of the groove 59 of the saw blade 55.

[0023] A fixing groove 512 is provided through the outer surface of the saw blade 55 near the drive disc 53. The fixing bar is strip-shaped, and a fixing rod 513 is slidably arranged inside the fixing groove 512. There are two fixing rods 513 arranged parallel to each other, and the two ends of the two fixing rods 513 are respectively fixedly connected to the inner surfaces of the two sides of the outer shell 1.

[0024] Fixing plates 514 are fixedly connected to the inner surfaces of both sides of the outer shell 1. The fixing plates 514 are L-shaped. Limiting plates 515 are elastically slidably inserted into the fixing plates 514. A pressing plate 516 is fixedly connected to the end of the limiting plate 515 away from the fixing plate 514. The pressing plate 516 is set in the same shape as the fixing plate 514. The outer surface of the pressing plate 516 presses against the outer surface of the saw blade 55. The pressing plate 516 and the fixing plate 514 are set in a highly elastic state through the limiting plate 515. The two ends of the pressing plate 516 are slidably connected to the inner surface of the outer shell 1.

[0025] Second embodiment: as follows Figures 1 to 8 As shown, the stabilizing mechanism 6 includes a stabilizing groove 61, which is symmetrically opened on both sides of the fixing groove 512. A stabilizing plate 62 is slidably arranged inside the stabilizing groove 61. The two ends of the stabilizing plate 62 are fixedly connected to the inner surface of the outer shell 1. The upper and lower surfaces of the stabilizing plate 62 are symmetrically hinged with a snap-fit ​​plate 63 by a torsion spring. The maximum rotation angle of the snap-fit ​​plate 63 is forty-five degrees.

[0026] The saw blade 55 has symmetrical auxiliary grooves 64 on both sides of one end near the drive disc 53. A sealing cover 65 is slidably inserted into the auxiliary groove 64. The outer surface of the sealing cover 65 is fixedly embedded in the inner surfaces of both sides of the outer shell 1. The sealing cover 65 fastens the stabilizing plate 62 and the snap-fit ​​plate 63.

[0027] The saw blade 55 has a filling groove 66 inside, and a compression bladder 67 is fixedly installed in the filling groove 66. The side surface of the saw blade 55 is provided with a liquid inlet 68, of which there are two liquid inlets 68, and the liquid inlets 68 are connected to the internal cavity of the compression bladder 67.

[0028] A pressure strip 69 is fixedly connected to the bottom of the compression bladder 67. The pressure strip 69 is elastically slidably connected to the bottom of the filling groove 66. A toggle block 610 is fixedly connected to the bottom surface of the pressure strip 69. The bottom of the toggle block 610 is set in the slide groove 59 of the saw blade 55. A sponge strip 611 is fixedly embedded inside the locking strip 510. The internal cavity of the locking strip 510 is connected to the internal cavity of the compression bladder 67.

[0029] During operation, when the electric chainsaw is needed, the handheld casing 1 can be moved to the designated position. The switch 3 on the casing 1 controls the motor 51 to start. Once started, the motor 51 drives the drive disc 53 via the drive shaft 52, causing it to rotate. The rotation of the drive disc 53 then controls the movement of the chain 56 connected to it. The rapidly moving chain 56, combined with the blade 57, achieves cutting. During the movement of the chain 56, the connecting piece 58 on the inner side of the chain 56 is positioned within the groove 59 of the saw blade 55. The connecting piece 58 limits the movement of the chain 56, ensuring it always moves along the edge of the saw blade 55, thus improving the stability of the electric chainsaw. A retaining strip 510 is installed within the groove 59 of the saw blade 55, and limiting grooves 511 are provided on both sides of the connecting piece 58 of the chain 56. This allows the limiting groove 511 on the connecting piece 58 to engage with the locking strip 510 in the slide groove 59 when the chain 56 moves, thereby limiting the relative positioning of the connecting piece 58 and the locking strip 510 in the slide groove 59. This ensures that the chain 56 remains close to the edge of the saw plate 55 during movement, preventing the chain 56 from being stretched and falling off the saw plate 55 during long-term operation. This significantly improves the working stability of the electric chainsaw, especially its stability during long-term operation. The inner end of the saw plate 55 is pressed against the outer surface of the pressing plate 516. That is, when the saw plate 55 is installed, its inner end is under strong elastic compression between the pressing plate 516 and the limiting plate 515, and is basically fixed by the fixing groove 512 and the fixing rod 513. At the same time, the two sides of the fixing groove 512... A stabilizing groove 61 is provided on the side, and a stabilizing plate 62 is slidably disposed within the stabilizing groove 61. This creates a multi-level fixing effect through the stabilizing plate 62, the fixing rod 513, and the pressing plate 516, significantly improving the stability of the saw blade 55 during operation. Simultaneously, the saw blade 55 and the fixing plate 514 are in an elastic compression state, ensuring that the outer end of the saw blade 55 always exerts an expansion and compression force on the chain 56. This keeps the chain 56 in a stretched state during operation, preventing loosening and unstable connection between the chain 56 and the saw blade 55 after prolonged use. This also enables the electric chainsaw to have an automatic adjustment function, automatically maintaining the working stability of the chain 56. Furthermore, because the two sides of the stabilizing plate 62 are hinged with locking plates 63 via torsion springs, the saw blade 55... After installation, the inclined limiting action of the locking plate 63 prevents the saw blade 55 from moving to one side of the outer casing 1. It only moves outward when the chain 56 is loose, thus locking the chain 56 and significantly improving the stability of the saw blade 55 during operation. The auxiliary groove 64 and the sealing cover 65 further limit the movement stability of the saw blade 55, ensuring that it can only move laterally outward, further improving working stability. At the same time, the sealing cover 65 can also relatively seal the fixing groove 512 and the stabilizing groove 61, preventing debris generated during cutting from entering the fixing groove 512 and the stabilizing groove 61 and affecting working stability. Before the electric chainsaw starts working, lubricating oil is injected into the compression bladder 67 in the filling groove 66 through the liquid inlet 68.When the chain 56 moves, its connecting piece 58 squeezes the actuating block 610, causing the actuating block 610 to move intermittently upwards. This, in turn, pushes the pressure bar 69 upwards within the filling groove 66, squeezing the compression bladder 67. The lubricating oil inside the compression bladder 67 is then delivered to the sponge strip 611 in the retaining strip 510. The lubricating oil in the sponge strip 611 lubricates the limiting groove 511 at the connecting piece 58, significantly improving the working stability of the chain 56 and preventing it from jamming. Because the compression bladder 67 is intermittently squeezed, it experiences intermittent high and low pressure states. Under high pressure, lubricating oil is delivered to the sponge strip 611; under low pressure, lubricating oil is absorbed from the sponge strip 611. This significantly improves the uniformity of lubrication while avoiding oil waste, thus avoiding the uneven lubrication and dripping waste caused by applying lubricating oil directly to the chain 56 in existing lubrication structures.
