Detailed Embodiments

[0017] The following is a further specific description of the technical solution of the present invention through embodiments and in combination with the attached Figure 1-2 ,.

[0018] A debris recycling device for furniture production includes a dust suction hood 2 installed below the operating table 1. A dust discharge port 3 communicating with the dust suction hood 2 is provided on the operating table 1. A connecting pipe 4 is provided at the rear end of the dust suction hood 2, and a corrugated pipe 5 is provided on the connecting pipe 4:

[0019] A sleeve 6 is arranged inside the open end of the corrugated pipe 5. One end of the sleeve 6 is provided with an annular seat 7 located outside the corrugated pipe 5, and a circular pipe 8 is sleeved outside the annular seat 7. A circle of arc-shaped grooves are correspondingly arranged on the inner side wall of the circular pipe 8 and the outer side wall of the annular seat 7. A number of steel balls 9 are arranged in the two groups of arc-shaped grooves. By the way that the steel balls 9 abut against the arc-shaped grooves, the circular pipe 8 is prevented from slipping off the annular seat 7, and it is also convenient for the circular pipe 8 to rotate on the annular seat 7. The end of the connecting pipe 4 is provided with a circular ring 10 attached to the annular seat. A sealing mechanism 11 is arranged between the circular ring 10 and the annular seat 7. The circular ring 10 is located inside the circular pipe 8, and the circular pipe 8 and the circular ring 10 are fixedly connected by screwing. An external thread is arranged on the outer side wall of the circular ring 10, and an internal thread screwed with the external thread is arranged on the inner side wall of the circular pipe 8;

[0020] One end of the dust suction hood 2 is provided with a plurality of V-shaped elastic pieces 12 extending into the circular pipe 8. A clamping groove 13 for accommodating one end of the V-shaped elastic piece 12 is arranged around the inner side wall of the open end of the circular pipe 8. A magnetic ring 14 is also sleeved outside the plurality of V-shaped elastic pieces 12. A convex block 15 magnetically connected to the magnetic ring 14 is arranged on the connecting pipe 4, and the convex block 15 is located between the magnetic ring 14 and the dust suction hood 2.

[0021] In this embodiment, the sleeve 6 and the corrugated pipe 5 are fixedly connected by bonding, and the sleeve 6 and the annular seat 7 are fixedly connected.

[0022] As Figure 1 、 2 shown, the cross section of the clamping groove 13 is in a right triangle structure, and the clamping groove 13 is located between the circular ring 10 and the magnetic ring 14.

[0023] The sealing mechanism 11 includes a strip-shaped groove 111 arranged around the end face of the annular seat 7. A sealing ring 112 is arranged in the opening of the strip-shaped groove 111, and the sealing ring 112 is fixedly connected to the inner bottom wall of the strip-shaped groove 111 through a spring 113. One end of the sealing ring 112 extends outside the strip-shaped groove 111 and abuts against the end face of the circular ring 10.

[0024] The using method of the present invention: As Figure 1 shown, the upper end face of the dust suction hood 2 is provided with an opening, the operating platform 1 is arranged on the upper end face of the dust suction hood 2, and the dust discharge port 3 of the operating platform 1 is communicated with the dust suction hood 2. When in use, the exhaust fan connected to the corrugated pipe 5 works to generate negative pressure inside it, so that the generated debris enters the dust removal hood 2 through the dust discharge port 3, and then is extracted through the connecting pipe 4, the sleeve 6 and the corrugated pipe 5;

[0025] As Figure 1 、 2As shown, the circular tube 8 is screwed to the circular ring 10, and then the corrugated pipe 5 and the connecting pipe 4 are connected in series through components such as the sleeve 6. At this time, one end of the V-shaped elastic piece 12 hooks the side wall of the card slot 13, thereby preventing the circular tube 8 from moving leftward and separating from the circular ring 10;

[0026] When it is necessary to disassemble and separate the corrugated pipe 5 and the connecting pipe 4, only need to move the magnetic ring 14 leftward to separate it from the convex block 15, and at the same time compress multiple groups of V-shaped elastic pieces 12 so that one end of it slides out of the card slot 13. At this time, the circular tube 8 can be rotated to drive the arc-shaped groove to rotate while the steel ball 9 rotates, and at the same time drive the internal thread at its end to rotate on the circular ring 10, so that the circular tube 8 is separated from the circular ring 10, so as to realize the disassembly of the corrugated pipe 5 and the connecting pipe 4, thereby facilitating the operation inside the corrugated pipe 5;

[0027] During installation, the circular tube 8 is sleeved on the circular ring 10 and rotated, so that the circular tube 8 drives the arc-shaped groove to rotate while the steel ball 9 rotates, and at the same time the circular tube 8 is screwed to the circular ring 10. When the annular seat 7 moves slowly and contacts the circular ring 10, the circular ring 10 will resist the sealing ring 112 extending outside the strip-shaped groove 111 and compress the spring 113, so that the sealing ring 112 slowly moves into the strip-shaped groove 111. When the circular ring 10 is attached to the annular seat 7, the sealing ring 112 can seal the gap between the circular ring 10 and the annular seat 7. When rotating the circular tube 8, it is necessary to move the magnetic ring 14 leftward to squeeze the V-shaped elastic piece 12, so as to facilitate the circular tube 8 to be sleeved on multiple groups of V-shaped elastic pieces 12. After the circular tube 8 is installed, move the magnetic ring 14 rightward so that it is magnetically connected to the convex block 15 to prevent it from moving leftward and squeezing the V-shaped elastic piece 12. At this time, the V-shaped elastic piece 12 stretches and one end of it is stuck into the card slot 13 to pull the circular tube 8 to prevent it from moving leftward.

[0028] The above has described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
