Description

Technical Field

[0001] The utility model relates to the technical field of hand push saws, in particular to an anti-splash protective cover for a hand push saw. Background Art

[0002] The safety guard is a protective device installed on mechanical equipment to protect the personal safety of the operator. Its function is to isolate the person from the moving parts of the equipment so that no part of the human body can directly enter the dangerous area that may cause mechanical injury. Since the amount of wood used is relatively large, the application of hand push saws is very extensive. However, the existing hand push saws are often not equipped with a protective guard during use or the effect of the protective guard is not obvious, resulting in frequent safety accidents for users, or wood chips flying around during use, affecting the user's vision and polluting the environment.

[0003] The publication (announcement) number is CN207273401U, which discloses a hand-pushing saw safety shield, including a top plate, a shield fixedly connected to the top of the top plate, a buffer device provided on the front and back surfaces of the shield, an air compressor and a motor fixedly connected to the bottom of the inner wall of the top plate from left to right in sequence, and the motor fixedly connected to a saw blade via an output shaft, a nozzle connected to the air compressor fixedly connected to one side of the top of the inner wall of the shield via a connecting plate, and a side of the elastic plate away from the support rod penetrates the baffle and extends to the inside of the buffer groove. The utility model relates to the technical field of hand-pushing saws. The hand-pushing saw safety shield solves the problem that the hand-pushing saw often has no shield or the effect of the shield is not obvious during use, can effectively prevent the user from being in danger during use, so that the quality of the obtained wood is relatively high, the waste of time is reduced, and the work efficiency is improved at the same time.

[0004] Although the above scheme improves the safety of the hand push saw when in use and prevents wood chips from flying by blowing, the cutting assembly is fixedly assembled inside the top plate. After long-term use, it is difficult for personnel to disassemble, clean and maintain the cutting assembly. The blown wood chips easily enter the top plate with the active area of ​​the saw blade, and it is troublesome for personnel to collect and process the wood chips. For this reason, we propose a splash-proof protective cover for a hand push saw. Utility Model Content

[0046] The following is the working principle of the utility model:

[0047] The protective box 201 and the cover plate 206 on the top surface of the rectangular frame plate 1 form a closed cover body outside the cutting assembly 4. By holding the turntable to control the screw rod 203 to rotate forward and backward on the strip box 202, one of the support blocks 204 threadedly connected to the screw rod 203 is subjected to force to drive the support sleeve 205 to rise and fall on the strip box 202 to adjust the exposed area. The cover plate 206 is driven by the support sleeve 205 to adjust the distance with the protective box 201. The other support block 204 slides and rises on the guide rod 207 to cooperate with the movement of the cover plate 206. When the cover plate 206 moves down to close the protective box 201, the cutting assembly 4 also enters the protective box 201 synchronously. 01, after the cover plate 206 is moved up and adjusted, the cutting assembly 4 is moved out of the protective box 201 for maintenance and cleaning. After the cut material is placed in the protective box 201 through the strip discharge trough and moves horizontally to contact the circular saw blade 404, the blower 302 draws the outside air of the protective box 201 and introduces it into the air outlet hopper 303 through the air outlet pipe 301. The air outlet hopper 303 located directly above the circular saw blade 404 guides the blowing air to blow the wood chips near the circular saw blade 404 from top to bottom. The wood chips move downward and fall directly from the inner area of ​​the rectangular frame plate 1 into the collecting box 304. Finally, the drop hopper 305 guides the wood chips to fall out in a concentrated manner to complete the unloading.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
