Description

Technical Field

[0001] The present invention relates to the technical field of chain saws, and specifically relates to a chain saw adjusting mechanism. Background Art

[0002] As is well known, a chain saw, also known as an oil saw, is a hand-held saw powered by a gasoline engine and is mainly used for logging and lumbering. Its working principle is that the staggered L-shaped blades on the saw chain move horizontally to perform a shearing action. Chain saws are generally divided into motorized chain saws, non-motorized chain saws, etc.

[0003] When the chain saw is not in use, in order to avoid the sharp blades on the serrated chain of the chain saw from accidentally injuring the staff, a protective cover is usually sleeved on the serrated chain when it is not in use. However, due to the overly single function of the existing protective cover, it does not have the function of being adjustable into a splash-proof baffle when the chain saw is in use; for this reason, we propose a chain saw adjusting mechanism.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, so it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide a chain saw adjusting mechanism to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A chain saw adjusting mechanism, comprising: a chain saw body and a protection component;

[0007] The chain saw body includes a chain saw main body. A guide plate is fixedly installed on the chain saw main body. A serrated chain is rotatably connected to the guide plate. A support block and a support plate are respectively fixedly connected to the outside of the chain saw main body. A first threaded rod is threadedly connected to the inside of the support block. One end of the first threaded rod is fixedly connected to a pushing block. A connecting block is closely attached to the outside of the pushing block. One side of the connecting block is fixedly connected to a connecting rod. One side of the support plate is fixedly connected to a plate body. The inside of the plate body is slidably connected to the connecting rod. One end of the connecting rod is fixedly connected to a clamping block;

[0008] The protection component includes a first protection plate and a second protection plate sleeved outside the serrated chain. A positioning groove is opened on one side of the first protection plate. The other side of the first protection plate is hinged to the second protection plate. A fixing block is fixedly connected to the other side of the first protection plate. A second threaded rod is threadedly connected to the inside of the fixing block. A movable plate is slidably connected to the inside of the fixing block. One side of the movable plate is fixedly connected to a connecting plate. A plurality of third springs are uniformly fixedly connected to one side of the connecting plate. One end of each third spring is fixedly connected to the fixing block. A threaded groove is opened on the outside of the second protection plate.

[0009] By adopting the above technical solution, after the main body of the chain saw is started, it can drive the serrated chain to rotate on the guide plate, so that the serrated chain can work. And when the first protection plate and the second protection plate are used as anti-spray plates when not in use, by tightening the first threaded rod, the pushing block can be driven to squeeze the two connecting blocks at the same time, so that the two connecting blocks can drive the two clamping blocks to move away from each other through the connecting rod, and further enable the two clamping blocks to tightly press against the positioning groove of the first protection plate, so that the first protection plate can be fixed on the main body of the chain saw; in addition, the second protection plate can be vertically folded on the first protection plate, and by screwing the second threaded rod into the threaded groove, the vertical state of the first protection plate and the second protection plate can be positioned. And when the first protection plate and the second protection plate are used as protective sleeves for the serrated chain, by loosening the movable plate, the connecting plate can drive the movable plate to press against one side of the second protection plate under the reset action of the third spring, so that the first protection plate and the second protection plate can be sleeved on the serrated chain in a flat state.

[0010] Preferably, one end of the second threaded rod is fixedly connected with a block body, and a groove is opened on one side of the block body.

[0011] By adopting the above technical solution, it is convenient to insert a wrench into the block body to operate the second threaded rod.

[0014] Preferably, a second spring is sleeved on the connecting rod, and both ends of the second spring are fixedly connected with the connecting block and the plate body respectively.

[0015] By adopting the above technical solution, after the connecting block loses the extrusion force of the pushing block, the connecting rod can drive the clamping block to loosen the pressing against the positioning groove under the reset action of the second spring, so that it is convenient to remove the first protection plate from the main body of the chain saw.

[0016] Preferably, flanges are fixedly connected to the sides of the first protection plate and the second protection plate close to the serrated chain.

[0017] By adopting the above technical solution, the protection effect of the first protection plate and the second protection plate on the serrated chain can be improved.

[0018] Preferably, an empty groove is opened inside the second protection plate, and an acrylic glass plate is fixedly embedded inside the empty groove.

[0019] By adopting the above technical solution, the second protective plate can perform the function of preventing splashing without affecting the operator's line of sight when operating the chain saw.

[0020] Preferably, a movable rod is fixedly connected to the outside of the chain saw main body. One end of the movable rod is fixedly connected with a stop block. A limiting plate for inserting into the positioning groove is slidably connected to the movable rod. A first spring is sleeved on the movable rod, and two ends of the first spring are respectively fixedly connected with the stop block and the limiting plate.

[0021] By adopting the above technical solution, the limiting plate can be inserted into the positioning groove under the reset action of the first spring, so as to facilitate the first protective plate and the second protective plate to be firmly sleeved on the sawtooth chain.

[0022] Preferably, a pulling ear is fixedly connected to the side of the limiting plate away from the chain saw main body.

[0023] By adopting the above technical solution, it is convenient to pull the limiting plate.

[0024] Preferably, a convex block is fixedly connected to the end of the first threaded rod away from the pushing block.
