Anti-side-slip dust-free electric circular saw

Abstract

This utility model relates to the field of circular saw technology and discloses an anti-slip dust-free circular saw, comprising: a motor housing, a fixed protective cover fixedly installed on the outer wall of the motor housing, a handle fixedly installed on the side of the motor housing, and a battery box fixedly installed at the end of the handle away from the motor housing. Through the overall design of the side-slip protection mechanism, when the saw blade extends into the interior of the object being cut, the outer wall of the object limits the telescopic protective cover, causing the moving block to slide on the outer wall of the slide bar, while simultaneously compressing the elastic element. If side-slip occurs accidentally, this structure will slide off the object being cut. At this time, the telescopic protective cover will lose its blocking and limiting function. The initial elastic force of the elastic element pushes the telescopic protective cover back to its original position, covering the exposed saw blade again, thus achieving the anti-slip protection function, reducing the probability of other injuries caused by the saw blade, and improving the safety of the structure.

Description

Technical Field

[0001] This utility model relates to the field of electric circular saw technology, specifically to an anti-slip dust-free electric circular saw. Background Technology

[0002] An electric circular saw is a widely used power-operated cutting tool in construction, woodworking, and manufacturing. Its core working principle involves an electric motor driving a circular saw blade to rotate at high speed, using the cutting force of the saw teeth to precisely cut various materials. Its core components include the motor, saw blade, and safety guard. Commonly used in construction, woodworking, and other fields, it is portable and efficient. It is available in both plug-in and rechargeable types, and safety precautions must be taken when using it.

[0003] Traditional circular saws lack anti-slip protection, with the blade exposed underneath. If the blade slips while being used by hand, the exposed blade can easily injure the operator or other objects, resulting in low safety. Utility Model Content

[0004] The purpose of this utility model is to provide a dust-free electric circular saw with anti-slip properties, which solves the problem in the prior art that if the saw blade accidentally slips, the exposed blade is very likely to cause injury.

[0005] This utility model provides the following technical solution: a dust-free electric circular saw with anti-slip properties, comprising:

[0006] A motor box, a fixed protective cover is fixedly installed on the outer wall of the motor box, a handle is fixedly installed on the side of the motor box, a battery box is fixedly installed at the end of the handle away from the motor box, a control button is fixedly installed on the outer wall of the handle, a handle is fixedly installed on the top of the handle, and a saw blade is detachably connected to the inner cavity of the fixed protective cover.

[0007] A side-slip protection mechanism is mounted on a fixed protective cover and is used to provide anti-side-slip protection.

[0008] A dust suppression mechanism is installed on the outer wall of the motor box, and the dust suppression mechanism is used to reduce the impact of smoke and dust on the working environment.

[0009] The side-slip protection mechanism includes a connecting block and a telescopic protective cover. The connecting block is fixedly installed on the outer wall of the fixed protective cover. A fixed block is fixedly installed on the outer wall of the connecting block. A sliding rod is slidably connected to the inner wall of the fixed block. A movable block is fixedly installed at the bottom of the sliding rod. A pin cylinder is fixedly installed at the bottom of the movable block. An elastic element is fixedly installed at the top of the movable block. The top of the elastic element is fixedly installed at the bottom of the fixed block.

[0010] As a preferred embodiment of the above technical solution, a pin is movably inserted into the inner cavity of the pin cylinder, the telescopic protective cover is fixedly installed at the end of the pin, and a disassembly bolt is threadedly connected to the outer wall of the pin cylinder, the threaded end of the disassembly bolt movably abutting against the outer wall of the pin.

[0011] As a preferred embodiment of the above technical solution, a reinforcing rib is fixedly installed on the outer wall of the telescopic protective cover, a through groove is opened on the outer wall of the telescopic protective cover, and a transparent observation window is fixedly installed on the inner wall of the through groove.

[0012] As a preferred embodiment of the above technical solution, the dust suppression mechanism includes a connecting seat, which is fixedly installed on the back of the motor box. A frame-shaped seat is fixedly installed on the back of the connecting seat, and an air purification cylinder is detachably connected to the inner cavity of the frame-shaped seat.

[0013] As a preferred embodiment of the above technical solution, an air intake hose is fixedly connected to the top of the air purifier cylinder, the end of the air intake hose away from the air purifier cylinder is fixedly connected to the top of the fixed protective cover, and a stainless steel mesh is fixedly installed on the side of the air purifier cylinder away from the connecting seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a lateral slip protection mechanism. When the saw blade extends into the object being cut, the outer wall of the object limits the telescopic protective cover, causing the moving block to slide on the outer wall of the slide rod. Simultaneously, the elastic element is compressed. If lateral slippage occurs, the structure will slide off the object being cut. At this point, the telescopic protective cover loses its blocking and limiting function. The initial elastic force of the elastic element pushes the telescopic protective cover back to its original position, covering the exposed saw blade again. This achieves the anti-lateral slippage protection function, reduces the probability of the saw blade causing other damage, and improves the safety of the structure. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-slip dust-free electric circular saw, comprising:

[0024] A motor box 1 is provided. A fixed protective cover 14 is fixedly installed on the outer wall of the motor box 1. A handle 11 is fixedly installed on the side of the motor box 1. A battery box 12 is fixedly installed at the end of the handle 11 away from the motor box 1. A control button 13 is fixedly installed on the outer wall of the handle 11. A handle 16 is fixedly installed on the top of the handle 11. A saw blade 15 is detachably connected to the inner cavity of the fixed protective cover 14.

[0025] Side slip protection mechanism 2 is installed on the fixed protective cover 14 and is used to provide anti-side slip protection.

[0026] Dust suppression mechanism 3 is installed on the outer wall of motor box 1. Dust suppression mechanism 3 is used to reduce the impact of smoke and dust on the working environment.

[0027] The side-slip protection mechanism 2 includes a connecting block 21 and a telescopic protective cover 28. The connecting block 21 is fixedly installed on the outer wall of the fixed protective cover 14. A fixed block 22 is fixedly installed on the outer wall of the connecting block 21. A sliding rod 23 is slidably connected to the inner wall of the fixed block 22. A moving block 24 is fixedly installed at the bottom of the sliding rod 23. A pin cylinder 26 is fixedly installed at the bottom of the moving block 24. An elastic element 25 is fixedly installed at the top of the moving block 24. The top of the elastic element 25 is fixedly installed at the bottom of the fixed block 22. The motor box 1 contains a motor that drives the saw blade 15 to rotate and perform cutting work. The battery box 12 contains a battery that powers the motor. The motor can be controlled to work or pause by pressing or releasing the control button 13. It is worth noting that the battery, motor, control button 13, and saw blade 15 in this solution are commercially available devices that can be purchased by those skilled in the art. The devices have not been structurally modified in this document. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them skillfully. Therefore, this article will not elaborate on this point. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge. When the saw blade 15 extends into the interior of the object being cut, the outer wall of the object being cut will limit the telescopic protective cover 28, causing the moving block 24 to slide on the outer wall of the slide rod 23, while compressing the elastic element 25. If side slip occurs accidentally, this structure will slide off the object being cut. At this time, the telescopic protective cover 28 will lose its blocking and limiting function. The initial elastic force of the elastic element 25 will push the telescopic protective cover 28 to reset and cover the exposed saw blade 15 again, realizing the anti-side slip protection function. The user can hold it with both hands from the handle 11 and the handle 16 to increase stability.

[0028] As one implementation method in this embodiment, such as Figure 3 As shown, a pin rod 27 is movably inserted into the inner cavity of the pin cylinder 26, and a telescopic protective cover 28 is fixedly installed at the end of the pin rod 27. A disassembly bolt is threaded onto the outer wall of the pin cylinder 26, and the threaded end of the disassembly bolt movably abuts against the outer wall of the pin rod 27. Through the connection design of the pin cylinder 26 and the pin rod 27, it is convenient for users to disassemble and clean the entire telescopic protective cover 28. When disassembling, loosen the disassembly bolt on the pin cylinder 26, and then pull the pin rod 27 out of the inside of the pin cylinder 26.

[0029] As one implementation method in this embodiment, such as Figure 3As shown, a reinforcing rib 281 is fixedly installed on the outer wall of the telescopic protective cover 28. A through groove is opened on the outer wall of the telescopic protective cover 28, and a transparent observation window 282 is fixedly installed on the inner wall of the through groove. The telescopic protective cover 28 is made of plastic, and the reinforcing rib 281 is made of metal. The design of the reinforcing rib 281 can strengthen the telescopic protective cover 28. The transparent observation window 282 is made of transparent plastic, which makes it convenient for users to observe the cutting status.

[0030] As one implementation method in this embodiment, such as Figure 4 As shown, the dust suppression mechanism 3 includes a connecting seat 31, which is fixedly installed on the back of the motor box 1. A frame-shaped seat 32 is fixedly installed on the back of the connecting seat 31. An air purification cylinder 33 is detachably connected to the inner cavity of the frame-shaped seat 32. After the air purification cylinder 33 is inserted into the inside of the frame-shaped seat 32, the air purification cylinder 33 is fixed by turning the bolts on the frame-shaped seat 32. With this design, the user can clean and maintain the internal components of the air purification cylinder 33.

[0031] As one implementation method in this embodiment, such as Figure 4 As shown, an air suction hose 34 is fixedly connected to the top of the air purifier cylinder 33. The end of the air suction hose 34 away from the air purifier cylinder 33 is fixedly connected to the top of the fixed protective cover 14. A stainless steel mesh 35 is fixedly installed on the side of the air purifier cylinder 33 away from the connecting seat 31. The air suction hose 34 is used to connect the fixed protective cover 14 and the inner cavity of the air purifier cylinder 33 to facilitate the absorption of dust. The design of the stainless steel mesh 35 facilitates the exhaust of air from inside the air purifier cylinder 33.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, an inner partition 36 is fixedly installed on the inner wall of the air purification cylinder 33. A suction fan 37 is fixedly connected to one side of the inner partition 36, and an air filter cartridge 38 is threadedly connected to the side of the inner partition 36 away from the suction fan 37. The switch of the suction fan 37 is located on the outer wall of the air purification cylinder 33. During the cutting process, the suction fan 37 is controlled to work, which can draw air from the inner cavity of the fixed protective cover 14 and then discharge it from the stainless steel mesh 35. At this time, the air is filtered through the air filter cartridge 38 to achieve the function of dust reduction and reduce environmental pollution.

[0033] Working principle: During use, the user holds the saw blade 15 with both hands from the handle 11 and the handle 16, and then presses the control button 13 to control the motor in the motor box 1 to work, which in turn drives the saw blade 15 to rotate, and then the cutting work can be carried out. During the cutting process, the suction fan 37 is controlled to work, which can draw air from the inner cavity of the fixed protective cover 14 and then discharge it from the stainless steel mesh 35. At this time, the air is filtered by the air filter cartridge 38 to achieve the function of dust reduction. When the saw blade 15 extends into the interior of the object being cut, the outer wall of the object being cut will limit the telescopic protective cover 28, causing the moving block 24 to slide on the outer wall of the slide rod 23, and at the same time compressing the elastic element 25. If the side slip occurs accidentally, this structure will slide off the object being cut. At this time, the telescopic protective cover 28 will lose its blocking and limiting function. The initial elastic force of the elastic element 25 will push the telescopic protective cover 28 to reset and cover the exposed saw blade 15 again, realizing the function of anti-side slip protection.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
