Description

Electric start chain saw

Technical Field

The invention relates to the technical field of chain saws, in particular to an electrically started chain saw.

Background Art

An electric start chain saw, also known as a gasoline chain saw or a gasoline powered saw, is a portable power saw that is characterized by the use of an electric starting system and a gasoline engine as a power source.

Electric start chain saws are mainly used in logging, timber making, wood cutting, branch pruning and wood product processing. The working principle is to quickly start the gasoline engine through the electric start system. The engine generates power and transmits the power to the saw chain through the transmission part. The saw chain rotates at high speed on the guide rail and cuts the wood with sharp teeth.

However, the cutting length of the chainsaw in the prior art is determined by the guide bar length and the chain length, and the existing chainsaw chain length and guide bar length are fixed, which results in the cutting length of the chainsaw being usually fixed and unable to freely control the length. When the chainsaw is unable to cut too long wood, it is necessary to replace the chainsaw of different sizes. Frequent replacement of different chainsaws during cutting work consumes a lot of time and reduces work efficiency. Therefore, it does not meet the existing needs. We have proposed an electric-start chainsaw.

The present invention has the following beneficial effects:

1. The electric-start chain saw can effectively extend the cutting length of the chain saw through the telescopic guide plate. The rotation of the rotating rod is realized through the drive of the driving motor and the meshing between the No. 1 bevel gear and the No. 2 bevel gear. The No. 2 guide plate can be further extended and retracted through the rotation of the rotating rod.

At the same time, it ensures the stability of the movement of the cutting chain when driven by the chain gear. The No. 1 guide plate is located at the connection with the chain clamping block and is designed with a larger entrance. This design can effectively ensure the sliding of the cutting chain in the chain mounting groove, and will not cause the cutting chain to be stuck due to the height difference caused by the telescopic chain clamping block.

3. The electric start chain saw can fill the gap caused by the sliding between the No. 1 plug-in block and the No. 1 plug-in slot through the design of the filling component and the transmission component, thereby effectively ensuring the stability of the guide plate connection. While the worm gear rotates, the No. 1 transmission gear and the No. 2 transmission gear, as well as the meshing of the No. 1 transmission gear and the driving tooth block, can directly drive the driving plate to slide in the No. 2 slide slot, and drive the driving plate to contact the contact bevel groove on the filling block. Since the contact bevel groove is contacted by the driving plate, the filling block slides in the filling groove. Through this sliding, the gap caused by the No. 1 plug-in block being separated from the No. 1 plug-in slot can be filled, thereby effectively improving the strength of the guide plate.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1. This embodiment is intended to promote the solution to the problem that the cutting length of the existing oil saw cannot be freely adjusted, resulting in the need to use oil saws of different specifications when cutting wood of different sizes. Please refer to Figures 1-12. An electric start oil saw includes an electric saw housing 1. A guide plate component 2 is installed on the electric saw housing 1. The guide plate component 2 includes a No. 1 guide plate 201. The No. 1 guide plate 201 is installed in the electric saw housing 1. A No. 1 plug-in slot 203 is opened on the No. 1 guide plate 201. A No. 1 plug-in block 204 is plugged into the No. 1 plug-in slot 203. The No. 1 plug-in block 204 is fixedly connected to the No. 2 guide plate 202. The No. 2 guide plate 202 is arranged on one side of the No. 1 guide plate 201. A guide plate telescopic driving device 3 is arranged between the No. 1 guide plate 201 and the No. 2 guide plate 202. Chain mounting grooves 207 are opened on the No. 1 guide plate 201 and the No. 2 guide plate 202. A chain assembly 4 is installed on the chain mounting groove 207.

The guide plate telescopic driving device 3 includes a No. 1 driving groove 301 opened in the No. 1 guide plate 201, a rotating rod 303 is rotatably connected in the No. 1 driving groove 301, a rotating groove 302 is opened in the No. 1 plug-in block 204, one end of the rotating rod 303 is fixedly connected to the screw rod 304, and a threaded block 306 is provided on the side wall of the screw rod 304. The threaded block 306 is fixedly connected in the No. 1 plug-in block 204, and the threaded block 306 is located at one end of the rotating groove 302.

The chain assembly 4 includes a cutting chain 401 , which is formed by connecting a plurality of chain blocks 402 . A chain gear 403 is disposed on one side of the cutting chain 401 . A drive shaft 404 is fixedly connected to one side of the chain gear 403 . The drive shaft 404 is fixedly connected to the electric saw housing 1 .

A No. 2 plug-in block 206 is fixedly connected to one side of the No. 1 guide plate 201, and the No. 2 plug-in block 206 is plugged into the No. 2 plug-in slot 205. The No. 2 plug-in slot 205 is provided in the No. 2 guide plate 202. A chain mounting slot 207 is provided on the No. 1 guide plate 201 and the No. 2 guide plate 202, and a cutting chain 401 is installed in the chain mounting slot 207.

One end of the rotating rod 303 is fixedly connected to a first bevel gear 307 , the first bevel gear 307 is meshingly connected to a second bevel gear 308 , one side of the second bevel gear 308 is fixedly connected to a driving motor 309 , and the driving motor 309 is installed in the electric saw housing 1 .

The electric start chain saw quickly starts the gasoline engine through the electric start system. The electric start system generates a strong torque at startup through a battery-powered electric motor, which drives the engine flywheel to rotate and then starts the gasoline engine. The system is composed of a control circuit, an electromagnetic coil, a rotor, etc., which realizes the conversion of electrical energy to mechanical energy. The engine drives the transmission system to drive the saw chain to rotate at high speed on the metal guide rail, thereby realizing the cutting of wood. At the same time, the lubrication system provides the necessary lubrication for the saw chain and the engine to ensure smooth cutting and extend the service life. The operating control device makes the operation more flexible and convenient (the starting principle of the electric start chain saw in the above content is the existing technology, so it will not be described in detail in this scheme).

The No. 2 guide plate 202 can be extended and retracted under the drive of the guide plate extension and retraction driving device 3. The rotating rod 303 can be driven to rotate by the driving motor 309 and the meshing between the No. 2 bevel gear 308 and the No. 1 bevel gear 307. The rotation of the rotating rod 303 drives the screw rod 304 fixed thereto to rotate synchronously. The meshing of the screw rod 304 and the threaded block 306 and the connection between the No. 1 plug-in slot 203 and the No. 1 plug-in block 204 can realize that the No. 2 guide plate 202 is driven to slide outward while the rotating rod 303 rotates. At the same time, the rotation of the rotating rod 303 can also synchronously drive the chain tensioning assembly 5 to move, thereby adjusting the movement trajectory of the cutting chain 401, thereby ensuring that the cutting chain 401 can fit in the chain mounting slot 207. Through this sliding and the fitting of the cutting chain 401, the length of the guide plate in the chain saw can be freely adjusted, and the position of the chain can be synchronously adjusted, thereby adjusting the different sizes of the chain saw.

The design of the No. 2 plug-in slot 205 and the No. 2 plug-in block 206 ensures that the empty part in the middle of the No. 2 guide plate 202 can be filled after sliding, ensuring that the track of the chain mounting slot 207 will not break, and effectively preventing the risk of the cutting chain 401 detaching from the chain mounting slot 207.

One end of the screw rod 304 is fixedly connected with an anti-slip block 305, and the anti-slip block 305 is slidably connected in the rotating groove 302. The design of the anti-slip block 305 effectively limits the sliding distance of the second guide plate 202, and effectively prevents the second guide plate 202 from sliding excessively, causing the two guide plates to detach from each other.

Embodiment 2: This embodiment is intended to promote the solution of the problem of adjusting the position of the chain while adjusting the length of the guide plate to ensure that the chain can always be in a taut state while the guide plate is extended and retracted. This embodiment is an explanation based on Embodiment 1. For details, please refer to FIGS. 1-12.

The chain assembly 402 includes a cutting plate 4021, a cutting block 4022 is fixedly connected to one side of the cutting plate 4021, a connecting shaft 4024 is rotatably connected inside the cutting plate 4021, a connecting plate 4023 is rotatably connected to the side wall of the connecting shaft 4024, and chain tensioning assemblies 5 are arranged at both ends of the connecting shaft 4024.

The cutting block 4022 located on the cutting board 4021 is used for cutting wood. The cutting chain 401 realizes high-speed movement under the drive of the chain gear 403. The cutting block 4022 can cut the wood through this high-speed movement. The connecting shaft 4024 is used to connect the cutting board 4021 and the connecting plate 4023. The connecting plate 4023 is used to connect two adjacent cutting boards 4021. Compared with the traditional connecting shaft 4024, the connecting shaft 4024 designed in this scheme is longer. This longer connecting shaft 4024 can better ensure the stability of the cutting chain 401 when sliding in the chain clamping block 501.

The chain tensioning assembly 5 includes a No. 1 slide groove 503 provided in the No. 1 guide plate 201 , a slider 502 is slidably connected in the No. 1 slide groove 503 , a chain clamping block 501 is fixedly connected to the slider 502 , and a connecting shaft 4024 is slidably connected in the chain clamping block 501 .

The chain clamping block 501 is used to clamp the chain assembly block 402. By sliding the connecting shaft 4024 in the chain clamping block 501, it can effectively ensure that the cutting chain 401 will not escape from the clamping of the chain clamping block 501 during the cutting work. At the same time, the sliding of the connecting shaft 4024 in the chain clamping block 501 can effectively ensure that the movement trajectory of the cutting chain 401 can be changed by lifting and lowering the chain clamping block 501.

A mounting groove 508 is provided in the No. 1 guide plate 201, and a worm 507 is rotatably connected in the mounting groove 508. The worm 507 is fixedly connected to the side wall of the rotating rod 303. A worm wheel 505 is provided on one side of the worm 507. The worm wheel 505 is rotatably connected in the No. 1 circular groove 506. The No. 1 circular groove 506 is provided in the No. 1 guide plate 201, and the No. 1 circular groove 506 is communicated with the mounting groove 508. The worm wheel 505 is meshingly connected with the No. 1 tooth block 504, and the No. 1 tooth block 504 is fixedly connected to one side of the slider 502.

When the rotating rod 303 rotates, the worm 507 located on the side wall of the rotating rod 303 rotates synchronously, and the meshing between the worm 507 and the worm wheel 505 drives the worm wheel 505 to rotate. Since the worm wheel 505 and the slider 502 are meshed and connected by the No. 1 tooth block 504, the rotation of the rotating rod 303 can effectively drive the slider 502 to slide up and down in the No. 1 slide groove 503. The sliding of the slider 502 can drive the chain clamping block 501 to clamp the cutting chain 401 to move up and down. The up and down movement of the cutting chain 401 can effectively ensure that the No. 2 guide plate 202 When extending or retracting, ensure that the cutting chain 401 is in a taut state and always fits the guide plate. This design effectively solves the problem that the telescopic guide plate cannot be extended or retracted because the total length of the chain remains unchanged. When the guide plate is extended to the maximum position, the chain clamping block 501 is at the highest point. At this time, the chain is elliptical. When the guide plate retracts inward, the chain clamping block 501 will move the chain downward. By increasing the chain stroke, the chain is always in a taut state and will not fall off the chain mounting groove 207, effectively preventing the chain from falling off due to the reduction in the length of the guide plate.

Referring to Figure 9, in order to ensure the stability of the movement of the cutting chain 401 when it is driven by the chain gear 403, the No. 1 guide plate 201 is designed with a larger entrance at the connection with the chain clamping block 501. This design can effectively ensure the sliding of the cutting chain 401 in the chain mounting groove 207, and will not cause the cutting chain 401 to be stuck due to the height difference caused by the telescopic design of the chain clamping block 501.

Embodiment three, this embodiment is intended to promote the solution to the problem that after the No. 2 guide plate is extended, a gap will appear in the middle of the guide plate, and the appearance of this gap will lead to a decrease in the overall strength of the guide plate. This embodiment is an explanation made on the basis of embodiment two. Specifically, please refer to Figures 1-12. A filling component 6 is provided in the No. 1 guide plate 201. The filling component 6 includes a filling groove 601 opened in the No. 1 guide plate 201, and a filling block 602 is slidably connected in the filling groove 601. The filling block 602 is provided with an interference inclined groove 603. One side of the filling block 602 is fixedly connected to a No. 1 spring 604, and the other end of the No. 1 spring 604 is fixedly connected in the filling groove 601.

A transmission assembly 7 is provided in the No. 1 guide plate 201, and the transmission assembly 7 includes a No. 2 slide groove 701 opened in the No. 1 guide plate 201, a driving plate 702 is slidably connected in the No. 2 slide groove 701, one end of the driving plate 702 is in contact with the intrusion inclined groove 603, a driving tooth block 703 is fixedly connected to the driving plate 702, the driving tooth block 703 is meshingly connected with a No. 1 transmission gear 704, the No. 1 transmission gear 704 is meshingly connected with a No. 2 transmission gear 705, the No. 2 transmission gear 705 is meshingly connected with a worm gear 505, the No. 1 transmission gear 704 is rotatably connected in the No. 2 circular groove 706, the No. 2 transmission gear 705 is rotatably connected in the No. 3 circular groove 707, and the No. 2 circular groove 706 and the No. 3 circular groove 707 are provided in the No. 1 guide plate 201.

After the No. 2 guide plate 202 is extended, a gap will appear in the middle of the guide plate. The appearance of this gap will lead to a reduction in the overall strength of the guide plate. In order to fill this gap, the filling component 6 is driven to move by the transmission component 7 while the rotating rod 303 rotates to fill this gap, thereby ensuring the strength of the guide plate. Furthermore, when the chain is running, it will not shake or deflect as a whole due to the instability of the guide plate, thereby reducing the swing amplitude of the chain, and effectively preventing the chain from falling off when cutting wood due to excessive swing amplitude of the chain.

While the worm gear 505 is rotating, the drive plate 702 can be directly driven to slide in the No. 2 slide groove 701 through the transmission of the No. 1 transmission gear 704 and the No. 2 transmission gear 705, and the meshing of the No. 1 transmission gear 704 and the driving tooth block 703, so as to drive the drive plate 702 to contact the contact bevel groove 603 on the filling block 602. Since the contact bevel groove 603 is contacted by the drive plate 702, the filling block 602 slides in the filling groove 601. Through this sliding, the gap generated after the No. 1 plug-in block 204 is separated from the No. 1 plug-in groove 203 can be filled, thereby effectively improving the strength of the guide plate and ensuring that the guide plate will not deflect or even break at the gap when the chain is running, thereby ensuring the stability of the chain and reducing the swing amplitude of the chain at the same time, thereby effectively preventing the chain from being separated when cutting wood due to excessive swing amplitude of the chain.

The No. 1 spring 604 connects the filling block 602 in the filling slot 601, which can effectively ensure that the filling block 602 can be quickly pulled back into the filling slot 601 when extension and retraction are not needed.

With reference to FIG12 , it can be seen that there are multiple groups of filling blocks 602. Therefore, no matter how long the No. 2 guide plate 202 is extended, a corresponding number of filling blocks 602 are resisted by the driving plate 702 to fill the gap. Through this design, each time the No. 2 guide plate 202 is extended a fixed distance, a corresponding filling block 602 is extended, which effectively ensures the flexibility of the telescopic guide plate.

It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
