DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0023] As Figures 1-5As shown in the figure, the present utility model provides a technical solution: a cutting device for building engineering materials with a protection structure, including a chassis 1. At the central position of the inner top of the chassis 1, a cutting machine 2 is fixedly installed, and the cutting machine 2 passes through the top of the chassis 1 and the top of the protection top plate 6. By providing the cutting machine 2, starting the cutting machine 2 controls the saw blade to rotate. When placing the building materials on the top of the protection top plate 6, under the action of gravity, the protection top plate 6 is pressed down close to the chassis 1 until the saw blade 2 passes through the protection top plate 6 to cut the building materials.

[0024] On both sides inside the chassis 1, mounting frames 3 are respectively fixedly installed. On both sides of the top of the mounting frame 3, pressure rods 4 are symmetrically slidably installed. The bottom ends of the two groups of pressure rods 4 pass through the mounting frame 3 and are fixedly installed with a connecting plate 5. The top ends of the four groups of pressure rods 4 are fixedly installed with a protection top plate 6 on the top of the chassis 1. A compression spring 7 is provided on the surface of the pressure rod 4 between the mounting frame 3 and the protection top plate 6. Due to the provision of the compression spring 7, when removing the building materials from the top of the protection top plate 6, under the rebound action of the compression spring 7, the protection top plate 6 is lifted away from the chassis 1, so that the saw blade of the cutting machine 2 is located in the gap between the chassis 1 and the protection top plate 6 to shield and protect the rotating cutting machine 2.

[0025] An adjusting stud 8 is fixedly installed between the connecting plate 5 and the protection top plate 6, and an adjusting nut 9 is provided on the surface of the adjusting stud 8 passing through the mounting frame 3 close to the protection top plate 6. By providing the adjusting nut 9, turning the adjusting nut 9 controls the position of the adjusting nut 9 on the surface of the adjusting stud 8, thereby adjusting the downward movement distance of the protection top plate 6.

[0026] At the central position on one side of the protection top plate 6, a concave block 10 is fixedly installed. At the central position on the top of the concave block 10, a rectangular groove one 11 is provided. On both sides of the top of the concave block 10, rectangular grooves two 12 are symmetrically provided. A moving screw 13 is rotatably installed inside the rectangular groove one 11. A limiting slide bar 14 is fixedly installed inside the rectangular groove two 12. A moving baffle 15 is slidably installed on the surface of the moving screw 13 and the two limiting slide bars 14 on the top of the concave block 10. By providing the moving screw 13 and the limiting slide bar 14, controlling the rotation of the moving screw 13 enables the moving baffle 15 to slide on the surface of the limiting slide bar 14, ensuring that the moving baffle 15 will not tilt or deflect during the movement, and at the same time facilitating the control of the cutting length of the building materials.

[0027] One end of the moving screw 13 passes through the rectangular groove one 11 and extends to the outside of the concave block 10 and is fixedly installed with a locking screw 16. A locking nut 17 is provided on the surface of the locking screw 16. One end of the locking screw 16 away from the moving screw 13 is fixedly installed with a rotating plate 18. Due to the provision of the locking nut 17, tightening the locking nut 17 against the concave block 10 locks and fixes the locking screw 16, ensuring that the moving screw 13 will not rotate randomly inside the rectangular groove one 11 and preventing the moving baffle 15 from sliding randomly.

[0028] On both sides of the top of the concave block 10, between the first rectangular groove 11 and the second rectangular groove 12, mounting blocks 19 are fixedly installed respectively. Inside one end of the mounting block 19, there is a mounting groove 20. Inside the mounting groove 20, a fixed insertion rod 21 is slidably installed, and one end of the fixed insertion rod 21 passes through the mounting groove 20 and extends to the outside of the mounting block 19. On one side surface of the fixed insertion rod 21 located inside the mounting groove 20, a limiting plate 22 is fixedly installed, and on the surface of the fixed insertion rod 21 located inside the mounting groove 20, there is a fixed spring 23. One end of the two groups of fixed insertion rods 21 located inside the mounting groove 20 passes through the mounting block 19 and is fixedly installed with a pull bar 24. By providing the fixed insertion rod 21 and the fixed spring 23, under the rebounding action of the fixed spring 23, the limiting plate 22 is pressed tightly against one side inside the mounting groove 20, thereby pushing the fixed insertion rod 21 out of the mounting groove 20 and inserting it into the corresponding fixed insertion hole 26 to clamp and fix the cushion block 25.

[0029] On one side of the concave block 10 and the two groups of mounting blocks 19, there is a cushion block 25. At both ends of the bottom of the cushion block 25, fixed insertion holes 26 are symmetrically provided, and the fixed insertion holes 26 correspond to the positions of the fixed insertion rods 21 and have the same shape. Due to the provision of the cushion block 25, there are various cushion blocks 25 with different shapes according to the shapes of building materials. When the fixed insertion rod 21 is inserted into the corresponding fixed insertion hole 26, it is convenient to disassemble and replace the cushion block 25, ensuring that when the building material is placed on the top of the cushion block 25, the central axis of the building material corresponds to the central axis of the cutting machine, and the building material will not deflect and move randomly during cutting.

[0030] The working principle of the present utility model is as follows:

[0031] Select the corresponding cushion block 25 according to the shape of the building material. After pulling the pull bar 24 to retract the fixed insertion rod 21 into the mounting groove 20, correspondingly snap the cushion block 25 on one side of the concave block 10, so that the fixed insertion hole 26 corresponds to the position of the fixed insertion rod 21. Release the pull bar 24, and under the rebounding action of the fixed spring 23, the fixed insertion rod 21 is pushed out of the mounting groove 20 and inserted into the corresponding fixed insertion hole 26, thereby clamping and fixing the cushion block 25. Hold the rotating plate 18 and rotate it to adjust the position of the movable baffle 15 on the top of the concave block 10, control the distance between the movable baffle 15 and the cushion block 25, and then tighten the locking nut 17 to lock and fix the movable screw 13. Turn the adjusting nut 9 on the adjusting screw 8 so that it abuts against the bottom of the protective top plate 6. Start the cutting machine 2 to drive the saw blade to rotate. Place the building material on the top of the cushion block 25, so that one end of the building material is in close contact with the movable baffle 15. Under the action of gravity, the building material and the protective top plate 6 move downward and approach the chassis 1, so that the saw blade of the cutting machine 2 extends out of the protective top plate 6 to cut the building material.

[0032] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] The above describes the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present patent.
