Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an oil control mechanism for assisting in oiling a saw chain of a saw. Background Technique

[0002] A saw, also known as a "power saw", is divided into a fixed type and a portable type. The saw blade is generally made of tool steel and has various shapes such as circular, strip-shaped, and chain-shaped. After using the saw for a long time, it is necessary to oil the surface of the saw chain to reduce friction loss.

[0003] For example, a saw with the authorization announcement number of "CN207358276U" reduces the volume and weight of the saw by making its axial structure smaller, and at the same time has high efficiency. In other technical solutions, the direction of the saw can be freely set, improving the applicability of the saw and having good market application prospects. However, after using the saw, the operator needs to apply oil to the surface of the chain by sticking oil with a brush. Since there is too much oil sticking to the surface of the chain, it causes excessive waste and reduces the working quality of the device. A large amount of wood chips will be generated during the working process of the device, and the flying wood chips are likely to cause injury to the operator, reducing the working safety of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that there is too much oil sticking to the surface of the chain, resulting in excessive waste and reducing the working quality of the device, and that the flying wood chips are likely to cause injury to the operator, reducing the working safety of the device, and to propose an oil control mechanism for assisting in oiling a saw chain of a saw.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an oil control mechanism for assisting in oiling a saw chain, including a saw body and a first armrest. The first armrest is fixedly connected to the left side of the saw body. A fixing frame is fixedly connected to the upper surface of the saw body. An auxiliary oil control device is arranged on the surface of the fixing frame. A first fixing plate is fixedly connected to the lower surface of the saw body. An auxiliary protection device is arranged on the surface of the first fixing plate.

[0007] Preferably, the auxiliary oil control device includes a cylinder body, a push rod, and an oil tank. The surfaces of the cylinder body and the oil tank are respectively fixedly connected to the surface of the fixing frame. The surface of the cylinder body is slidably connected to the surface of the push rod. A push block is fixedly connected to the surface of the push rod. The oil tank is connected to the cylinder body through a first one-way valve. One end of the cylinder body is fixedly connected and communicated with a second one-way valve.

[0008] Preferably, a rubber ring is fixedly connected to the outer wall of the push block, and the push block is attached to the surface of the cylinder body through the rubber ring.

[0009] Preferably, a second fixing plate is fixedly connected to the upper surface of the electric saw body, and a second armrest is fixedly connected to the surface of the second fixing plate.

[0010] Preferably, the auxiliary protection device includes a plate body, a fixing block, a fixing rod and a baffle. The baffle is movably connected to the surface of the first fixing plate through a rotating shaft. A fixing rod is fixedly connected to the surface of the first fixing plate. A spring is sleeved on the surface of the fixing rod. Two ends of the spring are respectively fixedly connected to the surface of the first fixing plate and the surface of the plate body. A fixing block is fixedly connected to the surface of the plate body, and a clamping block is fixedly connected to the surface of the plate body.

[0011] Preferably, the surface of the plate body is slidably connected to the surface of the fixing rod, and the surface of the clamping block is slidably connected to the surface of the first fixing plate.

[0012] For the oil control mechanism for auxiliary oiling of the electric saw chain proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the auxiliary protection device and the first fixing plate, the operator pulls the fixing block to drive the plate body and the clamping block to move outward. The plate body stretches the spring, rotates the baffle, makes the baffle perpendicular and aligns the through hole formed on the surface of the baffle with the surface of the clamping block. The operator releases the fixing block, and under the reaction force of the spring, the clamping block is driven to return to its original position. When the clamping block returns to its original position, it will pass through the through hole processed on the surface of the baffle, and the clamping block fixes the position of the baffle. By fixing the position of the baffle through the clamping block, it is avoided that the waste chips generated during the working process cause damage to the operator, and the working safety is improved.

[0013] Through the cooperation of the auxiliary oil control device and the electric saw body, the operator pulls the push rod to drive the push block to move upward. The second one-way valve prevents external air from entering the interior of the cylinder body. The movement of the piston on the surface of the push block causes negative pressure inside the cylinder body. The generated negative pressure pumps the oil inside the fuel tank into the interior of the cylinder body through the first one-way valve. Then, the operator pushes the push rod to drive the push block to move downward. The first one-way valve prevents the oil inside the cylinder body from flowing back into the fuel tank. The movement of the piston on the surface of the push block pushes the oil inside the cylinder body to drip onto the surface of the electric saw chain. By the operator pushing the push rod and the push block, the flow rate of the oil inside the cylinder body is controlled, avoiding excessive oil coating on the surface of the electric saw chain, causing waste, and improving the working quality.

The clamping block 305 is a square clamping block.

[0024] Refer to the attached Figure 1 、 2And 4: The auxiliary oil control device 2 includes a cylinder body 201, a push rod 202, and an oil tank 204. The surfaces of the cylinder body 201 and the oil tank 204 are fixedly connected to the surface of the fixing frame 8 respectively. The surface of the oil tank 204 is processed with a liquid inlet. The surface of the cylinder body 201 is slidably connected to the surface of the push rod 202. A push block 203 is fixedly connected to the surface of the push rod 202. A piston is provided on the surface of the push block 203. By pushing the push rod 202 to drive the push block 203, the oil tank 204 is connected to the cylinder body 201 through a first one-way valve 205. Through the first one-way valve 205, the oil inside the oil tank 204 can only flow into the inside of the cylinder body 201. One end of the cylinder body 201 is fixedly connected and communicated with a second one-way valve 206. Through the second one-way valve 206, the oil inside the cylinder body 201 can only be discharged.

[0025] Refer to the attached Figures 1-3 、5 and 6: The auxiliary protection device 3 includes a plate body 301, a fixing block 302, a fixing rod 303, and a baffle 306. A through hole with the size of the clamping block 305 is processed on the surface of the baffle 306. The baffle 306 is movably connected to the surface of the first fixing plate 5 through a rotating shaft. A fixing rod 303 is fixedly connected to the surface of the first fixing plate 5. A spring 304 is sleeved on the surface of the fixing rod 303. The elastic coefficient of the spring 304 meets the working requirements according to actual requirements. The two ends of the spring 304 are respectively fixedly connected to the surface of the first fixing plate 5 and the surface of the plate body 301. A fixing block 302 is fixedly connected to the surface of the plate body 301. By pulling the fixing block 302, the plate body 301 is driven to move. A clamping block 305 is fixedly connected to the surface of the plate body 301. The plate body 301 drives the clamping block 305 to move synchronously.

[0026] Working principle:

[0027] The operator injects oil through the liquid inlet of the oil tank 204 to prepare for lubricating the saw chain of the electric saw later.

[0028] The auxiliary protection process during the operation of the electric saw body:

[0029] When the operator uses the electric saw body 1, a large amount of sawdust will be generated. The operator pulls the fixing block 302 to drive the plate body 301 and the clamping block 305 to move outward. The plate body 301 stretches the spring 304. Rotate the baffle 306 to make the baffle 306 perpendicular and align the through hole opened on the surface of the baffle 306 with the surface of the clamping block 305. The operator releases the fixing block. Under the reaction force of the spring 304, the clamping block 305 is driven to return to its original position. When the clamping block 305 returns to its original position, it will pass through the through hole processed on the surface of the baffle 306. The clamping block 305 fixes the position of the baffle 306. According to the above operations, when the work is completed, the operator pulls the fixing block 302 again, rotates the baffle 306 back to its original position, and releases the fixing block 302. The auxiliary protection during the operation of the electric saw body is completed, avoiding damage to the operator caused by the sawdust generated when using the electric saw body 1.

[0030] Auxiliary oil control process during the use of a saw chain:

[0031] After the saw chain body 1 has been operating for a period of time and needs to be lubricated, the operator pulls the push rod 202 to drive the push block 203 upward. The second one-way valve 206 prevents external air from entering the interior of the cylinder body 201. The piston on the surface of the push block 203 causes a negative pressure inside the cylinder body 201. The negative pressure draws the oil inside the fuel tank 204 into the interior of the cylinder body 201 through the first one-way valve 205. Then, the operator pushes the push rod 202 to drive the push block 203 downward. The first one-way valve 205 prevents the oil inside the cylinder body 201 from flowing back into the fuel tank 204. The piston movement on the surface of the push block 203 pushes the oil inside the cylinder body 201 to drip onto the surface of the saw chain of the saw chain body 1, and in cooperation with the manual rotation or slow electric control rotation of the saw blade, the entire saw blade is coated, completing the auxiliary oil control process during the use of the saw chain. The operator controls the oil flow inside the cylinder body 201 to avoid excessive oil coating on the surface of the saw chain of the saw chain body 1.
