[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-7The easily assembled dust collector bag frame includes: an annular keel 1, a hollow circular seat 2, and multiple steel reinforcing keels 3. The bottom of the annular keel 1 has an annular groove 4, and the tops of the multiple steel reinforcing keels 3 extend into the annular groove 4. Arc-shaped blocks 5 are fixedly installed on each of the multiple steel reinforcing keels 3, and the multiple arc-shaped blocks 5 are all located within the annular groove 4. Female threads are formed on the inner wall of the outer ring of the annular groove 4, and male threads are formed on the outer ring wall of each of the multiple arc-shaped blocks 5. The female threads and male threads engage, thus... The annular keel 1 can be screwed onto multiple steel keels 3 for easy assembly and disassembly. Multiple insertion holes 6 are provided on the top of the hollow round base 2. Insertion folding strips 7 are fixedly installed on multiple steel keels 3. The bottom ends of multiple steel keels 3 are in contact with the top of the hollow round base 2. The multiple insertion folding strips 7 pass through multiple insertion holes 6 and contact the inner wall of the corresponding insertion hole 6. In order to fix the insertion folding strips 7 in the insertion hole 6, an inserting mechanism is provided in the hollow round base 2.

[0025] The aforementioned locking mechanism includes multiple transverse locking slots 8, each located on one side of multiple insertable folded strips 7. Multiple positioning plates 9 are fixedly installed on the top inner wall of the hollow circular base 2. Each positioning plate 9 has a sliding linkage rod 10 mounted on it. A transverse locking head 11 is fixedly installed at the ends of the linkage rods 10 that are far apart from each other. One side of each transverse locking head 11 extends into the multiple transverse locking slots 8. An abutment adapter block 12 is fixedly installed at the ends of the linkage rods 10 that are close to each other. A first return spring 14 is sleeved on each linkage rod 10, and one end of the first return spring 14 is fixedly engaged with the abutment adapter block 12. One end is fixedly connected to the other end, and the other end is fixedly connected to the positioning piece 9. The first return spring 14 has a large elastic coefficient. The elastic force of the first return spring 14 can firmly push the transverse insert head 11 into the transverse groove 8, thereby achieving a stable positioning effect on the insert folding strip 7. In addition, the bottom of each of the multiple insert folding strips 7 is provided with a first inclined sliding edge, and the top of each of the multiple transverse insert heads 11 is provided with a second inclined sliding edge. The multiple first inclined sliding edges are respectively adapted to the multiple second inclined sliding edges. This design can make the transverse insert head 11 automatically insert into the transverse groove 8 when the insert folding strip 7 is inserted into the insertion port 6, improving the convenience of operation.

[0026] In this method, in order to simultaneously remove the positioning effect of multiple plug-in folding strips 7 later, abutment slots 13 are provided on multiple abutment adapter blocks 12. A downward pressing rod 15 is slidably installed on the top of the hollow round seat 2. The bottom end of the downward pressing rod 15 extends into the hollow round seat 2 and is fixedly installed with a circular mounting piece 16. Multiple abutment pressing heads 17 are fixedly installed on the bottom of the circular mounting piece 16. The multiple abutment pressing heads 17 are respectively adapted to the multiple abutment slots 13. A pressing head is fixedly installed on the top of the downward pressing rod 15. A second return spring is sleeved on the downward pressing rod 15. The top end of the two reset springs is fixedly connected to the pressing head, and its bottom end is fixedly connected to the top of the hollow round seat 2. In addition, the bottom inner wall of the multiple abutting grooves 13 is set as an inclined sliding wall, and the bottom of the multiple abutting heads 17 is provided with a third inclined sliding edge. The multiple inclined sliding walls are respectively adapted to the multiple third inclined sliding edges. By applying downward pressing force to the pressing head, the multiple abutting heads 17 can be lowered, thereby forming a cooperation with the abutting grooves 13, and the multiple transverse inserting heads 11 are simultaneously brought out of the transverse inserting grooves 8, thereby forming a quick disassembly of the steel keel 3.

[0027] In the above method, in order to ensure that the contact head 17 rises and falls linearly, four columns arranged in a ring array are slidably installed on the top of the hollow round seat 2. The bottom ends of the four columns are fixedly connected to the circular mounting plate 16, thereby playing a limiting role.

[0028] The working principle of the easily assembled dust collector bag frame provided by this utility model is as follows:

[0029] In the initial state, the annular keel 1, the hollow round seat 2, and the multiple steel keels 3 are in a separated state;

[0030] When it is necessary to assemble and install the ring keel 1, hollow round seat 2, and multiple steel keels 3, first place the hollow round seat 2 on the platform, then pick up one of the steel keels 3 and insert the plug-in folding strip 7 on it into one of the insertion slots 6. During the insertion process, the first inclined sliding edge at the bottom of the plug-in folding strip 7 will contact the second inclined sliding edge on the corresponding transverse insert head 11. When the two contact, the plug-in folding strip 7 continues to press down, which will apply a pushing force to the transverse insert head 11, causing the transverse insert head 11 to move horizontally. The corresponding first return spring 14 is then subjected to... The force is under tension until the first inclined sliding edge and the second inclined sliding edge separate. The end of the transverse insert head 11 will then abut against one side of the insert folded strip 7. After the bottom end of the steel keel 3 contacts the top of the hollow round seat 2, it indicates that the insert folded strip 7 is installed in place. At this time, the transverse insert head 11 is horizontally aligned with the corresponding transverse insert groove 8. In an instant, the first return spring 14 pulls back, bringing the transverse insert head 11 into the transverse insert groove 8, thereby completing the assembly of one steel keel 3. Then, the remaining steel keels 3 are installed in the same way as above.

[0031] After all the steel keel 3 are installed, take out the ring keel 1, align the tops of the multiple steel keels 3 with the ring groove 4, and then lower the ring keel 1. When the inner wall of the ring groove 4 contacts the outer wall of the arc block 5, start rotating the ring keel 1. The two form a spiral connection, so that the ring keel 1 gradually rotates onto the multiple steel keels 3 until the top of the steel keel 3 contacts the top inner wall of the ring groove 4. At this time, the installation of the ring keel 1 is completed. The entire frame is now assembled and can be installed and used in the dust collector.

[0032] In subsequent use, when the entire frame needs to be dismantled, simply rotate the ring keel 1 out, and then apply downward pressure to the pressing head. This will bring down multiple abutment heads 17. When the third inclined sliding edge at the bottom of the abutment head 17 contacts the inclined sliding wall in the corresponding abutment groove 13, it will provide a pushing force to the abutment adapter block 12, causing the abutment adapter block 12 to move away from the plug-in folding strip 7. Finally, the transverse insert head 11 will be brought out of the transverse insert groove 8, and then the steel keel 3 can be removed.

[0033] Compared with related technologies, the dust collector bag frame that is easy to assemble provided by this utility model has the following beneficial effects:

[0034] This utility model provides a dust collector bag frame that is easy to assemble. Through the threaded engagement between the arc-shaped block 5 and the inner wall of the annular groove 4, the annular keel 1 can be quickly installed on multiple steel keels 3. Furthermore, through the lateral locking of the transverse insert head 11 and the transverse insert groove 8, the steel keel 3 can be quickly fixed on the hollow round seat 2. The entire assembly process is simple and quick, and easy to operate in practice. Compared with the traditional welding process, this method is faster, easier to disassemble and assemble, and facilitates the subsequent recycling of metal parts.
