Description

Technical Field

[0001] This utility model relates to the field of chainsaw structure technology, and in particular to a chainsaw. Background Technology

[0002] A chainsaw is a portable cutting machine powered by an internal combustion engine. It mainly consists of a two-stroke gasoline engine, a guide plate, a saw chain, a clutch, a fuel tank, and an operating control system. The engine drives the saw chain to rotate at high speed around the guide plate, and the sharp teeth on the saw chain enable rapid cutting of wood. Its significant advantage is that it is not limited by power supply and exhibits strong adaptability in field operations. With a specialized saw chain, it can also cut special materials such as concrete and ice. Modern chainsaws generally adopt shock absorption design, electronic ignition, and air filtration systems, which improve work efficiency while optimizing operating comfort.

[0003] Traditional chainsaws typically use simple guards, which not only hinder the normal operation of the chainsaw but also fail to provide effective protection in critical moments. When there is a risk of the saw chain falling off or breaking, traditional protective devices cannot detect and warn in real time, nor can they effectively prevent it. Fallen saw teeth or chains may injure people, causing minor injuries or even amputation, posing a serious safety hazard.

[0004] Therefore, in view of the fact that the traditional chainsaw has a simple structure, cannot perform real-time detection and reminders, and cannot effectively resist, thus posing serious safety hazards, a chainsaw with real-time monitoring, alarm reminders, and active protection devices can be designed. Utility Model Content

[0005] To overcome the problems of traditional chainsaws having a simple structure, being unable to provide real-time detection and alerts, and being unable to effectively resist attacks, thus posing serious safety hazards.

[0006] The technical solution of this utility model is as follows: a chainsaw includes a chainsaw shell; it also includes a mounting base plate, the mounting base plate is fixedly connected to one side of the chainsaw shell, a first limiting slide rail is fixedly connected to the mounting base plate, a first baffle is provided on one side of the mounting base plate, a first slide groove is slidably connected to the first limiting slide rail, the first slide groove is fixedly connected to the first baffle plate, a first rack is fixedly connected to the mounting base plate, a rotating shaft is rotatably connected to the first baffle plate, two gears are fixedly connected to both sides of the rotating shaft, the gears are meshed with the first rack plate, a hydraulic cylinder is fixedly connected to the bottom of the mounting base plate, a hydraulic rod is fixedly connected to the output end of the hydraulic cylinder, a connecting support is fixedly connected to the other end of the hydraulic rod, and the connecting support and the first baffle plate are fixedly connected.

[0007] Preferably, when the chainsaw malfunctions, the hydraulic cylinder outputs pressure to the hydraulic rod, pushing the hydraulic rod to move linearly. This causes the hydraulic rod to drive the first baffle to move linearly through the connecting support, causing the first groove on the first baffle to slide on the first limit rail. Simultaneously, the gear meshing on the first rack rotates, and the gear drives the rotating shaft to rotate. This causes the gears on both sides of the rotating shaft to rotate simultaneously, thus completing the emergency protection measure of the first baffle when the chainsaw malfunctions.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of a chainsaw, including a chainsaw housing 1 and a mounting base 2. The mounting base 2 is fixedly connected to one side of the chainsaw housing 1, and a first limiting slide rail 3 is fixedly connected to the mounting base 2. A first baffle 5 is provided on one side of the mounting base 2. A first slide groove 502 is slidably connected to the first limiting slide rail 3 and is fixedly connected to the first baffle 5. A first rack 4 is fixedly connected to the mounting base 2, and a rotating shaft 6 is rotatably connected to the first baffle 5. Two gears 7 are fixedly connected to both sides of the rotating shaft 6 and mesh with the first rack 4. A hydraulic cylinder 8 is fixedly connected to the lower part of the mounting base 2. A hydraulic rod 9 is fixedly connected to the output end, and a connecting support 10 is fixedly connected to the other end of the hydraulic rod 9. The connecting support 10 and the first baffle 5 are fixedly connected. When the chainsaw malfunctions, the hydraulic cylinder 8 outputs pressure to the hydraulic rod 9, pushing the hydraulic rod 9 to move linearly. This causes the hydraulic rod 9 to drive the first baffle 5 to move linearly through the connecting support 10, causing the first slide groove 502 on the first baffle 5 to slide on the first limit slide rail 3. At the same time, the gear 7 meshing on the first rack 4 rotates, and the gear 7 drives the rotating shaft 6 to rotate. This causes the gears 7 on both sides of the rotating shaft 6 to rotate simultaneously, thus completing the emergency protection measure of the first baffle 5 when the chainsaw malfunctions.

[0026] Please see Figures 1-4 In this embodiment, a second baffle 11 is provided on one side of the first baffle 5. A second limiting slide rail 501 is fixedly connected to the first baffle 5, and a second slide groove 1101 is slidably connected to the second limiting slide rail 501. The second slide groove 1101 is fixedly connected to the second baffle 11. When the second baffle 11 moves, the second slide groove 1101 slides on the second limiting slide rail 501, completing the full extension of the first baffle 5 and the second baffle 11. A second rack 12 is fixedly connected to the second baffle 11, and the second rack 12 meshes with... A gear 7 is connected to the chain saw. When the gear 7 rotates, it drives the second rack 12 meshing on both sides of the gear 7 to move linearly, thereby driving the second baffle 11 to move linearly. A drive motor 14 is fixedly connected inside the chainsaw housing 1. The output end of the drive motor 14 is fixedly connected to the saw blade body 16. A guide plate 15 is fixedly connected to the chainsaw housing 1. The guide plate 15 and the saw blade body 16 are rotatably connected. The drive motor 14 outputs torque to the saw blade body 16, causing the saw blade body 16 to rotate on the guide plate 15 to complete the cutting work.

[0027] Please see Figures 1-5In this embodiment, two saw blade detectors 13 are provided on both sides of the saw blade body 16. The saw blade detectors 13 are fixedly connected to the chainsaw housing 1. The saw blade body 16 is monitored in real time by the saw blade detectors 13 on both sides of the saw blade body 16. An alarm light 22 is fixedly connected to the chainsaw housing 1. The saw blade detectors 13, the alarm light 22, and the hydraulic cylinder 8 are electrically connected. When the saw blade detectors 13 detect that the saw blade body 16 is at risk of breakage, they transmit an electrical signal to the alarm light 22 and the hydraulic cylinder 8, causing the alarm light 22 to light up to remind the user, and at the same time, the hydraulic cylinder 8 to start working. The chainsaw housing 1 is fixedly connected to... The first handle 17 has an emergency brake button 18 movably connected to it. The emergency brake button 18 is electrically connected to the drive motor 14. The user can lift the chainsaw from the rear using the first handle 17. In case of an emergency, the drive motor 14 can be stopped by using the emergency brake button 18. The second handle 19 is fixedly connected to the chainsaw housing 1. The brake handle 20 is fixedly connected to the top of the chainsaw housing 1. The oil tank 21 is fixedly connected inside the chainsaw housing 1. The user can lift the chainsaw from the front using the second handle 19 and control the rotation speed of the saw blade body 16 using the brake handle 20. Power is provided by the oil tank 21.

[0028] During operation, the user lifts the chainsaw from the rear using the first handle 17 and from the front using the second handle 19. The oil tank 21 provides power, causing the drive motor 14 to output torque to the saw blade body 16, causing it to rotate on the guide plate 15. The brake handle 20 controls the rotation speed of the saw blade body 16. Simultaneously, saw blade detectors 13 on both sides of the saw blade body 16 monitor it in real time. When a saw blade detector 13 detects a risk of breakage, it sends an electrical signal to the alarm light 22 and the hydraulic cylinder 8, illuminating the alarm light 22 and alerting the user. The user can then use the emergency brake button 18 to stop the drive motor 14 and simultaneously activate the hydraulic cylinder 8. Cylinder 8 outputs pressure to hydraulic rod 9, pushing hydraulic rod 9 to move linearly. Hydraulic rod 9 drives first baffle 5 to move linearly through connecting support 10. First groove 502 on first baffle 5 slides on first limit rail 3. At the same time, gear 7 meshing on first rack 4 rotates. Gear 7 drives shaft 6 to rotate. Gear 7 on both sides of shaft 6 rotates simultaneously, driving second rack 12 meshing on both sides of gear 7 to move linearly. This drives second baffle 11 to move linearly, causing second groove 1101 to slide on second limit rail 501. This completes the full extension of first baffle 5 and second baffle 11, providing emergency protection in case of abnormal chainsaw operation.

[0029] Through the above steps, using the first baffle 5 and the second baffle 11 in conjunction with multiple driving devices, a retractable safety protection device is achieved. This device will not interfere with the normal operation of the chainsaw, and can actively extend when the saw blade body 16 falls off or breaks, preventing the flying metal fragments from injuring the user. This improves safety during use and protects the user's personal safety. At the same time, a saw blade detector 13 and an alarm light 22 are installed. The saw blade detector 13 performs real-time detection of the saw blade body 16 to prevent dangerous accidents in advance, and the alarm light 22 reminds the user and makes risk predictions to minimize the degree of damage. This solves the problem that traditional chainsaws have simple structures, cannot perform real-time detection and warnings, and cannot effectively resist damage, resulting in serious safety hazards.
