Description

Technical Field

[0001] The invention relates to a cutting protection device, in particular to a wire trough cutting protection device. Background Art

[0002] A wire trough is a wire trough used to install and arrange wires. There are two main installation methods: open installation and concealed installation. Household wires are generally buried in walls or underground during renovation through wire troughs, and the specifications are in accordance with national standards. Concealed installation is generally used. However, as time goes by, wires will always be old and broken, and other problems may occur in the lines. Therefore, it is necessary to reach into the wall or the ground to cut the wire trough. For this operation, in order to facilitate the movement and transfer of cutting operations, the cutting equipment is often a handheld lightweight cutting machine. However, in this way, when workers use a portable cutting machine to cut the wall or the ground, they need to control the cutting depth while carrying the cutting machine, and can only cut one seam at a time. This is not only time-consuming and labor-intensive, but also difficult to control the cutting depth, and the cutting efficiency is low, which brings inconvenience to users. When people are close to the cutting site, they are also more likely to inhale flying dust, causing personal injury. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a wire trough cutting protection device, which can realize the precise locking of cutting depth and cutting distance, and the cutting automation degree, cutting efficiency and cutting accuracy are also higher, and at the same time it also has a better protection effect, and the safety of use can also be greatly improved.

[0004] The present invention provides the following technical solutions:

[0006] At this point, when the device is in use, it is only necessary to hold the outer cover and fit the open end of the protective cover to the wall or the ground. By starting the drive cylinder, the sawing group can be driven toward the wall or the ground to perform the cutting operation, and the cutting depth can be quickly read from the size entered by the ruler, and the cutting length can be quickly read by the distance the ruler travels in the groove.

[0012] Preferably, in order to improve the stability of the support of the second side frame, a group of springs are connected to the side of the second side frame away from the sawing shaft, and the other end of the spring is connected to the fixed side plate of the mounting frame. The spring is in a compressed state, thereby applying pressure to the second side frame toward the sawing shaft.

[0013] Preferably, the driving part includes two groups of Z-direction screw rods installed on the outer cover, the two groups of Z-direction screw rods are respectively screwed on both sides of the mounting cover, and are driven to rotate by a Z-direction motor to drive the mounting cover to drive the protective cover to move along the Z direction.

[0027] At this point, when the device is in use, it is only necessary to hold the outer cover and fit the open end of the protective cover 1 to the wall or the ground. By starting the drive cylinder 5, the sawing group 3 can be driven toward the wall or the ground to perform the cutting operation, and the cutting depth can be quickly read from the size entered by the ruler 9, and the cutting length can be quickly read by the distance the ruler 9 travels in the groove 8. The direction of the cutting length is the driving direction of the driving part 7. During cutting, since the protective cover 1 can completely cover the cutting position, the dust can be confined in the protective cover 1 to reduce the harm to outsiders.

[0028] A set of lock nuts 10 are connected to the external thread of the ruler 9, and a set of top bolts 11 are also threadedly installed in the slot 8 along the Z direction. Therefore, before cutting, the lock nuts 10 and the top bolts 11 can be rotated in advance to the corresponding positions of the scale lines of the ruler 9 and the scale lines next to the slot 8. At this point, when the drive cylinder 5 and the drive part 7 are driven, automatic limit locking can be achieved after moving to the corresponding position, thereby replacing the human eye observation of the position and achieving a more accurate cutting size.
