Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric chain saws, in particular to an electric chain saw with a chain adjusting mechanism. BACKGROUND

[0002] In the field of electric tools, electric chain saws are widely used in wood processing, forestry logging and other scenes as a kind of efficient cutting tool. The core of the electric chain saw is to drive the chain to move along the saw plate at high speed to achieve cutting through the motor. The stability and tension of the chain directly affect the cutting efficiency, safety and equipment life. Therefore, the electric chain saw with chain adjusting function becomes the key to improve the performance of the tool. Such equipment needs to realize the anti-falling, automatic tensioning and stable lubrication of the chain to adapt to the long-time high-intensity operation demand, which is an important equipment to ensure the continuity and reliability of the cutting operation.

[0003] The existing electric chain saw has obvious limitations in chain adjustment and stability. In terms of chain fixation, traditional equipment lacks effective limiting structure, and the chain is prone to looseness after long-time work due to stretching, and even falls off the saw plate, especially when running at high speed, which poses a safety hazard. In terms of tension adjustment, traditional equipment relies on manual adjustment and cannot automatically compensate for the tension according to the degree of chain wear, resulting in unstable connection between the chain and the saw plate, affecting cutting accuracy and efficiency. The single fixing method cannot resist the vibration during cutting, and the saw plate is prone to shaking, further aggravating the wear and looseness of the chain. In addition, the traditional lubrication method is mostly direct smearing, which causes uneven distribution of lubricating oil and easy dripping and waste, and the debris generated during cutting easily enters the transmission components, causing the chain to jam, which restricts the working stability and service life of the electric chain saw.

The upper and lower surfaces of the stabilizing plate 62 are symmetrically hinged with clamping plates 63 through torsional springs. The maximum rotation angle of the clamping plate 63 is forty-five degrees.

[0026] The two side surfaces of one end of the saw plate 55 close to the driving disc 53 are symmetrically provided with auxiliary grooves 64. The auxiliary grooves 64 are slidably inserted with sealing covers 65. The outer surface of the sealing cover 65 is fixedly embedded in the inner surfaces of the two sides of the outer shell 1. The sealing cover 65 buckles the stabilizing plate 62 and the clamping plate 63.

[0027] The inner part of the saw plate 55 is provided with a filling groove 66. The filling groove 66 is fixedly installed with a pressing capsule 67. The side surface of the saw plate 55 is provided with liquid inlets 68. The liquid inlets 68 are provided with two. The liquid inlets 68 are in communication with the inner cavities of the pressing capsule 67.

[0028] The bottom of the pressing capsule 67 is fixedly connected with a pressure strip 69 which is elastically slidably connected to the bottom of the filling groove 66. The bottom surface of the pressure strip 69 is fixedly connected with a pushing block 610. The bottom of the pushing block 610 is arranged in the sliding groove 59 of the saw plate 55. The inner part of the clamping strip 510 is fixedly embedded with a sponge strip 611. The inner cavity of the clamping strip 510 is in communication with the inner cavity of the pressing capsule 67.

[0029] In work, when the electric chain saw needs to be used, the outer shell 1 can be moved to the specified position, the switch 3 on the outer shell 1 is controlled to start the motor 51, after the motor 51 is started, the driving shaft 52 drives the driving disc 53 to start rotating, so that the chain 56 connected to the driving disc 53 starts to move through the rotation of the driving disc 53, and the cutting is realized through the fast-moving chain 56 and the cutter head 57. In the process of moving the chain 56, the connecting piece 58 on the inner side of the chain 56 is in the sliding groove 59 of the saw plate 55, and the connecting piece 58 is used to limit the chain 56, so that the chain 56 always moves along the edge of the saw plate 55, thereby improving the stability of the electric chain saw. By setting the clamping strip 510 in the sliding groove 59 of the saw plate 55, and opening the limiting groove 511 on both sides of the connecting piece 58 of the chain 56, the limiting groove 511 on the connecting piece 58 of the chain 56 can be clamped on the clamping strip 510 in the sliding groove 59 when the chain 56 moves, and the connecting piece 58 and the clamping strip 510 in the sliding groove 59 are relatively limited, so that the chain 56 always closely adheres to the edge of the saw plate 55 when moving, avoiding the problem that the chain 56 is stretched and falls off the saw plate 55 in a long working state, greatly improving the working stability of the electric chain saw, especially the stability of long-time work. The inner end of the saw plate 55 is extruded on the outer surface of the extrusion plate 516, that is, the inner end of the saw plate 55 is in a strong elastic extrusion state between the extrusion plate 516 and the limiting plate 515 during installation, and a basic fixing effect is provided through the fixed groove 512 and the fixed rod 513. At the same time, the two sides of the fixed groove 512 are provided with a stable groove 61, and a stable plate 62 is slidably arranged in the stable groove 61, that is, a multi-stage fixing effect is formed among the stable plate 62, the fixed rod 513 and the extrusion plate 516, greatly improving the stability of the saw plate 55 during work. At the same time, the saw plate 55 and the fixed plate 514 are in an elastic extrusion state, so that the outer end of the saw plate 55 always has an expansion extrusion force on the chain 56, thereby making the chain 56 always in a stretched state during work, avoiding the problem that the chain 56 is loose and unstable in connection with the saw plate 55 after long-time use, and making the electric chain saw have an automatic adjusting function, automatically maintaining the working stability of the chain 56. Because the two side surfaces of the stable plate 62 are hinged with the clamping plate 63 through the torsion spring, after the installation of the saw plate 55 is completed, the clamping plate 63 is inclined and limited, so that the saw plate 55 cannot move to one side of the outer shell 1, and only moves outward to clamp the chain 56 when the chain 56 is loose, thereby further greatly improving the stability of the saw plate 55 during work. By setting the auxiliary groove 64 and the sealing cover 65, the movement stability of the saw plate 55 can be further limited, so that the saw plate 55 can only move outward horizontally, further improving the working stability. At the same time, the sealing cover 65 can also relatively close the fixed groove 512 and the stable groove 61, avoiding the debris generated during cutting from entering the fixed groove 512 and the stable groove 61 to affect the working stability. Before the electric chain saw works, lubricating oil is injected into the extrusion capsule 67 in the filling groove 66 through the liquid inlet 68,When the chain 56 moves, the connecting piece 58 will extrude the push block 610, so as to make the push block 610 intermittently move upwards, and then start to push the pressure strip 69 to move upwards in the filling groove 66 to extrude the extrusion capsule 67, so as to transport the lubricating oil in the extrusion capsule 67 to the sponge strip 611 in the card strip 510, and then lubricate the limiting groove 511 at the connecting piece 58 through the lubricating oil at the sponge strip 611, so as to greatly improve the working stability of the chain 56, and avoid the problem that the chain 56 is stopped during working. Since the extrusion capsule 67 is extruded intermittently, the inside of the extrusion capsule 67 is in an intermittent high pressure and negative pressure state, the lubricating oil is transported to the sponge strip 611 in the high pressure state, and the lubricating oil is reversely absorbed from the sponge strip 611 in the negative pressure state, so as to greatly improve the lubricating uniformity of the lubricating oil, and avoid the problem of waste of lubricating oil, and the problems of uneven lubrication and waste of oil caused by directly applying the lubricating oil on the chain 56 in the prior art lubricating structure.
