DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] As shown in Figures 1 to 6 The utility model discloses a quick detach with dust collection function table saw upper shield, including shield body 1, the bottom of shield body 1 is provided with the material knife 2, shield body 1 is fixed on the material knife 2 through locking assembly, the top of material knife 2 is provided with first slot 3 and second slot 4, the inner chamber of shield body 1 is fixedly installed with first locking pin 5, and first locking pin 5 is movably inserted in first slot 3.

[0022] Further, the locking assembly includes connecting rods 6, the number of connecting rods 6 is two, two connecting rods 6 are arranged on the two sides of shield body 1 respectively, a through hole 7 is formed in shield body 1, a second locking pin 8 located in the through hole 7 is fixedly connected between two connecting rods 6, the second locking pin 8 is movably inserted in the second slot 4, and recesses are formed in the connecting rods 6.

[0023] In the prior art, the material knife 2 on the table saw is installed on the motor assembly and is lifted together with the saw blade, when the first locking pin 5 and the second locking pin 8 are located in the first slot 3 and the second slot 4 respectively, the shield body 1 can be locked and positioned on the material knife 2, so that the shield body 1 is located on the top of the saw blade to achieve the protection effect.

[0024] Further, the shield body 1 is rotatably connected with a locking trigger 9, an arc-shaped hole 10 is formed in the shield body 1, a round pin 11 located in the arc-shaped hole 10 is fixedly connected to the locking trigger 9, and the round pin 11 is rotatably connected with the two connecting rods 6.

[0025] By rotating the locking trigger 9 to drive the round pin 11 to rotate along the inner wall of the arc-shaped hole 10, the two connecting rods 6 can be driven to move, so that the connecting rods 6 can drive the second locking pin 8 to move in the through hole 7, and then the connecting rods 6 can move into or move out of the second slot 4, that is, the locking or loosening state between the shield body 1 and the material knife 2 is achieved, which is convenient for the staff to install or disassemble the shield body 1.

[0026] Further, the two sides of the shield body 1 are provided with protective plates 12, and the protective plates 12 are connected between the shield body 1 by bolts.

[0027] The bolts on the protective plates 12 do not need to be tightened, so that when the wood below the protective plates 12 is inserted and cut, the protective plates 12 can be rotated upward.

[0028] Further, the inside of the shroud body 1 is provided with a dust suction air duct 13, and the top of the shroud body 1 is provided with a dust outlet 14 in communication with the dust suction air duct 13.

[0029] By connecting the dust collector pipe to the dust outlet 14, the dust generated during cutting can be sucked through the dust suction air duct 13, thereby improving the air environment around the cutting table.

[0030] The working principle and use process of the utility model are as follows:

[0031] When the staff needs to disassemble the shroud body 1 for cleaning or replacement, the staff can rotate the locking trigger 9 in the locking assembly, so that the round pin 11 drives the connecting rod 6 to move, so that the locking trigger 9 is rotated to the state shown in the figure. Figure 6 Due to the movement of the connecting rod 6, the second locking pin 8 is close to the first locking pin 5 along the inner wall of the through hole 7, so that the second locking pin 8 is moved out from the inside of the second slot 4, thereby releasing the locking and limiting between the shroud body 1 and the distributing knife 2, that is, the shroud body 1 can be disassembled from the distributing knife 2. When installing the shroud body 1, after the first locking pin 5 and the second locking pin 8 preliminarily position the position of the shroud body 1 on the distributing knife 2, the locking trigger 9 is reversely rotated to lock and limit the shroud body 1 on the distributing knife 2, which is convenient to operate and improves the work efficiency of the staff.

[0032] The above embodiments are only used to help understand the method of the utility model and its core idea. It should be noted that for ordinary skilled persons in the technical field, without departing from the principle of the utility model, the utility model can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the utility model claims.
