[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3In an embodiment of the utility model, a cutting protection device for steel structure processing includes a base 1, a desktop cutting machine is installed on the top of the base 1, a protective cover 2 is mounted on the top of the base 1, the desktop cutting machine is located directly below the protective cover 2, a visualization window 3 is embedded at one end of the top of the protective cover 2, a guide groove 4 is opened at the other end of the top of the protective cover 2, and an auxiliary mechanism 5 is installed on the inner side of the protective cover 2;

[0020] The auxiliary mechanism 5 includes an arc-shaped bar 501 matching the curvature of the inner side of the protective cover 2, the arc-shaped bar 501 is tightly attached to the inner side of the guide groove 4, and a through hole 507 is provided on the arc-shaped bar 501 for the handle of the desktop cutting machine to pass through. A fixed seat 502 is fixedly connected to the inner end of the arc-shaped bar 501, and a shaft 503 is rotatably connected to the middle part of the fixed seat 502. A gear 504 is fixedly connected to one end of the shaft 503, and a wiper 506 is fixedly connected to the other end of the shaft 503 by bolts. An arc-shaped rack 505 is fixedly connected to the inner end of the protective cover 2 away from the visualization window 3, and the arc-shaped rack 505 is meshed with the gear 504; the fixed seat 502 and the shaft 503 are rotatably connected by a bearing;

[0021] The wiping member 506 is a brush roller, and the wiping member 506 in the rotating state is in full contact with the visualization window 3 to clean the dust adhering to the inner side of the visualization window 3; the outer arc surface of the arc strip 501 and the inner arc surface of the protective cover 2 are both smooth surfaces.

[0022] In this embodiment: Since the existing desktop cutting machine has fewer protective structures, especially when cutting hard steel structure metal parts, the cutting disc may break due to improper operation. During the cutting process, the breaking of the cutting disc may cause a very dangerous safety accident. Therefore, this solution installs a protective cover 2 on the outside of the desktop cutting machine, and a visualization window is embedded in the protective cover 2. An auxiliary mechanism 5 is also installed on the inside. The auxiliary mechanism 5, the protective cover 2 and the desktop cutting machine are used in combination to safely and effectively protect the operator and prevent the broken cutting disc from splashing and threatening personal safety. In addition, the visualization window 3 can observe the cutting status at any time, and the auxiliary mechanism 5 can also continuously wipe the visualization window 3 to ensure that the visualization window 3 always maintains a clear field of view, thereby facilitating the observation of the cutting status at all times without interfering with the cutting operation.

[0023] Specifically, the visualization window 3 in this solution is set on one side of the cutting part of the desktop cutting machine, which is convenient for observing the cutting state at all times. By pressing down the handle of the desktop cutting machine, the arc strip 501 can be driven to move back and forth along the length direction of the guide groove 4, and the guide groove 4 is completely blocked at the same time to prevent debris from splashing out of the guide groove 4. When it is necessary to cut the steel structure member, the steel structure member to be cut is fixed by the clamp on the desktop cutting machine, and then the operator presses down the handle of the desktop cutting machine to cut the steel structure member, and the cutting state is penetrated through the visualization window 3. It should be noted that when the operator is performing the cutting operation, he needs to stand close to the handle of the desktop cutting machine, and cannot stand in the direction of the openings on both sides of the protective cover 2.

[0024] When the handle of the desktop cutting machine is pressed down or lifted up, the protective cover 2 and the arc bar 501 slide relative to each other, and the moving arc bar 501 will drive the gear 504 to move. During the movement, the gear 504 is always engaged with the arc rack 505, thereby driving the gear 504 to rotate. The rotating gear 504 will drive the wiping piece 506 at the other end of the shaft 503 to rotate, and then the visualization window 3 is rolled and wiped to clean the dust adhering to the inside of the visualization window 3, so as to keep the field of view of the visualization window 3 clear at all times.

[0025] Please refer to Figure 3 The through hole 507 is located in the middle of the arc strip 501, and the through hole 507 is located in the middle of one side of the guide groove 4, the width of the guide groove 4 is larger than the outer diameter of the through hole 507; the through hole 507 is fixedly connected to the handle of the desktop cutting machine by strong glue.

[0026] In this embodiment, the handle of the desktop cutting machine passes through the through hole 507 and is located in the guide groove 4. The handle of the desktop cutting machine can move back and forth in the arc length direction of the guide groove 4, while driving the arc strip 501 to slide back and forth on the inner wall of the protective cover 2 to cover the guide groove 4 at all times.

[0027] Please refer to Figure 1 and Figure 2 Both ends of the upper surface of the base 1 are provided with through grooves 6 for the two ends of the auxiliary mechanism 5 to slide and extend.

[0028] In this embodiment: During the cutting process, part of the structure in the auxiliary mechanism 5 is in relative motion with the protective cover 2. To ensure the normal reciprocating movement of the handle of the desktop cutting machine, through grooves 6 need to be opened at both ends of the upper surface of the base 1 to prevent the auxiliary mechanism 5 from remaining smooth during the movement.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
