Technical Field

[0001] The utility model relates to the technical field of protective equipment, and specifically, to a protective device for a woodworking circular saw. Background Art

[0002] In the woodworking industry, a circular saw is a common tool used for cutting materials such as wood and boards. However, during the use of a circular saw, due to its high-speed rotating blade, there are relatively high safety risks. Once the operation is improper or the equipment fails, it may lead to accidents such as wood chips flying and the blade breaking, posing potential threats to the operators and the surrounding environment.

[0005] To achieve the above purpose, the utility model provides a protective device for a woodworking circular saw, including a protective cover. An adjustable height device is installed on the back of the protective cover. The adjustable height device is connected to a bracket through bolts. A connecting plate is installed at the top of the bracket. The adjustable height device includes a vertical plate. A long hole is vertically opened on the surface of the vertical plate. The rod part of the bolt is in vertical sliding fit with the long hole. One end of the bolt is locked and fixed through a locking nut. The other end of the bolt penetrates through the connecting plate and is installed with a screwing end.

[0006] Preferably, the bracket is of an L-shaped structure, and a support plate is installed at the bottom of the bracket.

[0007] Preferably, the width of the connecting plate is greater than the width of the long hole.

[0008] Preferably, the number of the bolts is two, which are respectively located at the upper end and the lower end of the connecting plate.

[0009] Preferably, the bottom end of the vertical plate is welded and fixed to the outer wall of the protective cover.

[0010] Preferably, the protective cover is of a semi-circular structure, with a semi-circular cavity inside, an opening at the bottom, and the opening facing downwards.

[0011] Preferably, the protective cover includes a housing, and an inner cushion layer is installed on the inner wall of the housing.

[0012] Preferably, the protective cover is a square tube structure made of steel plate material.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a protective device for a woodworking circular saw. As Figures 1-4 shown, it includes a protective cover 1 for protecting the woodworking circular saw. An adjustable height device 4 is installed on the back of the protective cover 1. The adjustable height device 4 is connected to a bracket 2 through a bolt 3. A connecting plate 21 is installed at the top of the bracket 2. The adjustable height device 4 includes a vertical plate 41. A long slot 42 is vertically formed on the surface of the vertical plate 41. The rod portion of the bolt 3 is in vertical sliding fit with the long slot 42. One end of the bolt 3 is locked and fixed through a locking nut 32. The other end of the bolt 3 passes through the connecting plate 21 and is provided with a screwing end 31. By rotating the locking nut 32, the adjustable height device 4 can be locked and fixed.

[0025] In this embodiment, the bracket 2 is an L-shaped structure, and a support plate 22 is installed at the bottom of the bracket 2 to ensure the stable support at the bottom of the bracket 2.

[0026] Specifically, the width of the connecting plate 21 is greater than the width of the long slot 42, so that the connecting plate 21 stably fits on the outer wall of the vertical plate 41 and will not pass through the long slot 42.

[0027] Furthermore, the number of bolts 3 is two, which are respectively located at the upper end and the lower end of the connecting plate 21 to ensure that the adjustable height device 4 is fully locked and fixed.

[0028] Furthermore, the bottom end of the vertical plate 41 is welded and fixed to the outer wall of the protective cover 1 to facilitate the connection between the adjustable height device 4 and the protective cover 1.

[0029] Furthermore, the protective cover 1 is a semi-circular structure, with a semi-circular cavity inside, and an opening is provided at the bottom, and the opening faces downward to facilitate the upper part of the woodworking circular saw.

[0030] Furthermore, the protective cover 1 includes an outer shell 11. The outer shell 11 is made of stainless steel material to ensure good strength. An inner cushion layer 12 is installed on the inner wall of the outer shell 11. The inner cushion layer 12 is made of fire-resistant asbestos material to prevent the outer shell 11 from being damaged by the sputtering of sparks.

[0031] Furthermore, the protective cover 1 is a square tube structure made of steel plate material to ensure stable and light structure.

[0032] When the woodworking circular saw protection device of the utility model is in use, it mainly uses the protective cover 1 to effectively block the splashing of wood chips and provide safety protection. The core structure of the device lies in its height-adjustable device 4, which enables the protective cover 1 to be adjusted in height according to different requirements of woodworking operations and circular saws.

[0033] In the initial state, the protective cover 1 is connected to the bracket 2 through the height-adjustable device 4 on its back. The L-shaped structure of the bracket 2 provides stable support, and the support plate 22 at its bottom further enhances the stability.

[0034] When it is necessary to adjust the height of the protective cover 1, the operator can loosen the locking nut 32 and then adjust the position of the protective cover 1 to the required height by sliding the bolt 3 in the long slot 42. Since the width of the connecting plate 21 is greater than that of the long slot 42, this ensures that the connecting plate 21 always stably fits on the outer wall of the vertical plate 41 during the adjustment process and will not shift.

[0035] After adjusting to the appropriate position, the bolt 3 is locked by rotating the locking nut 32, thereby fixing the height-adjustable device 4 and the protective cover 1 at the new height position. During this process, the two bolts 3 located at the upper and lower ends of the connecting plate 21 act together to ensure the stability and safety of the device.

[0036] During the working process of the woodworking circular saw, the semi-circular protective cover 1 effectively blocks the splashing of wood chips and the sputtering of sparks through its outer shell 11 and inner cushion layer 12, protecting the safety of the operator and the surrounding environment. The outer shell 11 is made of stainless steel material, ensuring the strength and durability of the device, while the inner cushion layer 12 is made of fire-resistant asbestos material, further enhancing the protection effect.

[0037] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection claimed by the utility model is defined by the appended claims and their equivalents.
