Description

Technical Field

[0001] This utility model relates to the field of chainsaw technology, specifically to a chainsaw protection device. Background Technology

[0002] A chainsaw is a hand-held saw powered by a gasoline engine, mainly used for logging and timber processing. Its working principle is based on the lateral movement of the L-shaped blades on the saw chain to perform the cutting action. Chainsaws are generally divided into motorized chainsaws and non-motorized chainsaws.

[0003] Chinese patent CN217621051U discloses a safety protection device for chainsaws, comprising a chainsaw body, a guide plate, and a chain. The chain is disposed on the outer wall of the guide plate, and the guide plate is disposed on one side of the chainsaw body. A protective mechanism is provided on one side of the chainsaw body, and a vibration damping mechanism is provided on the outer wall of the chainsaw body. By fitting a protective cover over the guide plate and chain, and then using the cooperation of an electric telescopic rod, a movable plate, and a guide rod, a pressure plate and an elastic rubber pad are driven to clamp the protective cover on both sides of the guide plate, thus fixing the protective cover. This protects the guide plate and chain, avoiding the problem of existing chainsaws where the guide plate and chain are exposed to the outside environment after use without a protective mechanism, making them susceptible to damage upon collision with hard objects. This device facilitates the protection of the guide plate and chain, improving their safety.

[0004] However, since there is no locking structure between the protective cover and the chainsaw body, the protective cover is only installed on the guide plate and chain of the chainsaw through a clamping structure. This makes the protective cover easy to detach due to external impact or shaking, thus failing to effectively protect the guide plate and chain. Therefore, a chainsaw protection device is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a chainsaw protection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chainsaw protective device, comprising a chainsaw body, a guide plate, and a chain; the chainsaw body is provided with a protective mechanism and a cooling mechanism; the protective mechanism includes a protective cover, the chainsaw body is provided with a fixing component, and the protective cover is provided with a clamping component; the fixing component includes a fixing block fixedly mounted on the chainsaw body, the fixing block having a slot, one end of the protective cover being inserted into the slot, the slot having a slot, the fixing block having a movable cavity, and a movable plate slidably disposed within the movable cavity; the movable plate... A wedge-shaped locking block is fixedly installed on one side of the movable plate, and a guide rod is fixedly installed on the other side of the movable plate. One end of the guide rod slides through the movable cavity and is fixedly connected to a pull handle. A spring is sleeved on the guide rod and is disposed between the movable cavity and the movable plate. A fixing hole is opened on the protective cover. The wedge-shaped locking block slides through the movable cavity and passes through the fixing hole to engage with the locking slot. The clamping assembly includes a threaded sleeve that passes through the protective cover. A threaded rod is internally threaded to the threaded sleeve. A hand-tightening block is fixedly connected to one end of the threaded rod. A clamping plate is rotatably connected to the other end of the threaded rod. An anti-slip pad is adhered to the clamping plate.

[0007] Preferably, the protective cover has a pull groove.

[0008] Preferably, a limiting rod is fixedly provided on the clamping plate, and one end of the limiting rod slides through the protective cover and is fixedly connected to a limiting block.

[0009] Preferably, the cooling mechanism includes a water tank fixedly mounted on the chainsaw body, and a water injection pipe is connected to the water tank.

[0010] Preferably, a water pump is installed on the chainsaw body, and a water inlet pipe is provided between the water inlet of the water pump and the water tank.

[0011] Preferably, a fixing plate is fixedly installed on the fixing block, a flexible hose is provided through the fixing plate, and a water mist nozzle is connected to the water outlet of the flexible hose.

[0012] Preferably, a water outlet pipe is provided between the hose and the water inlet and the water outlet of the water pump, and the water outlet pipe is connected to the hose through a threaded pipe joint.

[0013] Preferably, a handle is fixedly provided at one end of the chainsaw body, a carrying handle is fixedly provided on the chainsaw body, and a support pad is installed at the bottom of the chainsaw body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This chainsaw protective device works by inserting one end of the protective cover into the slot. When the protective cover is inserted, it will squeeze the wedge-shaped block, causing the wedge-shaped block to be squeezed into the movable cavity. At the same time, the moving plate squeezes the spring on the guide rod. When the protective cover and the slot are fully engaged, the wedge-shaped block will automatically pass through the fixing hole and be locked into the slot under the spring's rebound action, thus achieving the locking and fixing of the protective cover.

[0016] 2) This chainsaw protective device rotates the threaded rod connected to the threaded sleeve by rotating the hand-tightening block, thereby causing the clamping plate to move under the action of the thread and the guiding action of the limiting rod until the two clamping plates are clamped on both sides of the guide plate. The anti-slip pads on the clamping plates can increase the friction between the clamping plates and the guide plate, further improving the fixation of the protective cover.

[0017] 3) This chainsaw protection device uses a water pump to pump water from the tank into a flexible hose through the inlet and outlet pipes. The water is then atomized and sprayed out through a water mist nozzle. The sprayed water mist cools the guide plate and chain, reducing friction and heat buildup, thus improving the durability of the guide plate and chain and cutting efficiency. At the same time, the flexible nature of the hose allows for flexible adjustment of the spray direction of the water mist nozzle, and the sprayed water mist can also suppress dust generated during cutting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] Combination Figures 1-5 A chainsaw protection device includes a chainsaw body 1, a guide plate 2 and a chain 3. A handle 4 is fixedly installed at one end of the chainsaw body 1, a carrying handle 5 is fixedly installed on the chainsaw body 1, a support pad 6 is installed at the bottom of the chainsaw body 1, and a protective mechanism 7 and a cooling mechanism 8 are provided on the chainsaw body 1.

[0031] See Figure 1 Furthermore, the protective mechanism 7 includes a protective cover 71, a pull groove 72 is provided on the protective cover 71, a fixing component 73 is provided on the chainsaw body 1, and a clamping component 74 is provided on the protective cover 71.

[0032] See Figure 2 , Figure 3 and Figure 5 Furthermore, the fixing component 73 includes a fixing block 731 fixedly installed on the chainsaw body 1. The fixing block 731 has a slot 732. One end of the protective cover 71 is inserted into the slot 732. A slot 733 is provided in the slot 732. The fixing block 731 has a movable cavity 734. A movable plate 735 is slidably arranged in the movable cavity 734. A wedge-shaped locking block 736 is fixedly arranged on one side of the movable plate 735. A guide rod 737 is fixedly arranged on the other side of the movable plate 735. One end of the guide rod 737 slides through the movable cavity 734 and is fixedly connected to a handle 739. A spring 738 is sleeved on the guide rod 737 and is arranged between the movable cavity 734 and the movable plate 735. The protective cover 71 has a fixing hole 7310. The wedge-shaped locking block 736 slides through the movable cavity 734 and passes through the fixing hole 7310 to engage with the slot 733.

[0033] Specifically, by inserting one end of the protective cover 71 into the slot 732, the protective cover 71 will press the wedge-shaped block 736 when inserted, so that the wedge-shaped block 736 is pressed into the movable cavity 734. At the same time, the moving plate 735 presses the spring 738 on the guide rod 737. When the protective cover 71 is fully engaged with the slot 732, the wedge-shaped block 736 will automatically pass through the fixing hole 7310 and be locked into the slot 733 under the rebound action of the spring 738, thus achieving the locking and fixing of the protective cover 71.

[0034] See Figure 5 Furthermore, the clamping assembly 74 includes a threaded sleeve 741 that passes through the protective cover 71. The threaded sleeve 741 is internally threaded with a threaded rod 742. One end of the threaded rod 742 is fixedly connected to a hand-tightening block 743. The other end of the threaded rod 742 is rotatably connected to a clamping plate 744. An anti-slip pad 745 is adhered to the clamping plate 744. A limit rod 746 is fixedly provided on the clamping plate 744. One end of the limit rod 746 slides through the protective cover 71 and is fixedly connected to a limit block 747.

[0035] Specifically, by rotating the hand-tightening block 743, the threaded rod 742, which is threadedly connected to the screw sleeve 741, rotates, thereby causing the clamping plate 744 to move under the action of the thread and the guiding action of the limiting rod 746, until the two clamping plates 744 are clamped on both sides of the guide plate 2. The anti-slip pad 745 provided on the clamping plate 744 can increase the friction between the clamping plate 744 and the guide plate 2, further improving the fixation of the protective cover 711.

[0036] See Figure 4 Furthermore, the cooling mechanism 8 includes a water tank 81 fixedly mounted on the chainsaw body 1, a water injection pipe 82 connected to the water tank 81, a water pump 83 mounted on the chainsaw body 1, a water inlet pipe 84 connected between the water inlet of the water pump 83 and the water tank 81, a fixing plate 85 fixedly mounted on the fixing block 731, a flexible hose 86 extending through the fixing plate 85, a water mist nozzle 87 connected to the water outlet of the flexible hose 86, a water outlet pipe 88 connected between the flexible hose 86 and the water inlet and the water outlet of the water pump 83, and the water outlet pipe 88 and the flexible hose 86 connected by a threaded pipe joint 89.

[0037] Specifically, by starting the water pump 83, the water in the water tank 81 is pumped into the hose 86 through the inlet pipe 84 and the outlet pipe 88. The water is atomized and sprayed out through the water mist nozzle 87. The sprayed water mist can cool the guide plate 2 and the chain 3, reduce friction and heat accumulation, and improve the durability of the guide plate 2 and the chain 3 and the cutting efficiency. At the same time, the flexible nature of the hose 86 makes it easy to flexibly adjust the spray direction of the water mist nozzle 87, and the sprayed water mist can also suppress the dust generated during cutting.

[0038] In actual operation, when the chainsaw is not in use, insert one end of the protective cover 71 into the slot 732. When the protective cover 71 is inserted, it will squeeze the wedge-shaped block 736, causing the wedge-shaped block 736 to be squeezed into the movable cavity 734. At the same time, the moving plate 735 squeezes the spring 738 on the guide rod 737. When the protective cover 71 is fully engaged with the slot 732, the wedge-shaped block 736 will automatically pass through the fixing hole 7310 and be inserted into the slot 733 under the rebound action of the spring 738, thus achieving the locking and fixing of the protective cover 71.

[0039] Rotating the hand-tightening block 743 causes the threaded rod 742, which is threadedly connected to the screw sleeve 741, to rotate. This causes the clamping plate 744 to move under the action of the thread and the guidance of the limiting rod 746 until the two clamping plates 744 are clamped on both sides of the guide plate 2. The anti-slip pad 745 provided on the clamping plate 744 can increase the friction between the clamping plate 744 and the guide plate 2, further improving the fixation of the protective cover 711. At the same time, the elasticity of the anti-slip pad 745 can effectively prevent the clamping plate 744 from causing hard damage to the guide plate 2.

[0040] When using a chainsaw, by pulling the handle 739 outward, the guide rod 737 moves the wedge-shaped block 736 into the movable cavity 734 via the moving plate 735. Then, the protective cover 71 is pulled out of the slot 732 by pulling the groove 72, and the protective cover 71 can be removed and the chainsaw can be used.

[0041] Sufficient water is injected into the water tank 81 through the water injection pipe 82. The water in the water tank 81 is pumped into the hose 86 through the water inlet pipe 84 and the water outlet pipe 88 by starting the water pump 83. The water is atomized and sprayed out through the water mist nozzle 87. The sprayed water mist can cool the guide plate 2 and the chain 3, reduce friction and heat accumulation, and improve the durability of the guide plate 2 and the chain 3 and the cutting efficiency. At the same time, the flexible nature of the hose 86 makes it easy to flexibly adjust the spray direction of the water mist nozzle 87. The sprayed water mist can also reduce the dust generated during cutting, reduce the dust intake of users during operation, and protect the health of users.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
