DETAILED DESCRIPTION

[0028] The utility model will now be further described in detail with reference to the accompanying drawings.

[0029] See also Figure 1-6As shown, in this embodiment, a V-shaped filter with large air volume and high dust holding capacity is provided, including a bottom frame 1, a top frame 2, a support bar 4, and an outer frame 5. A plurality of fixing components are installed on the opposite surfaces of the bottom frame 1 and the top frame 2, and connecting components are installed at both ends of the support bar 4, and the connecting components cooperate with the fixing components. A filter element is arranged between the bottom frame 1 and the top frame 2, and a plurality of first V-shaped grooves 7 are opened on the top of the bottom frame 1, and T-shaped blocks 8 are installed in the plurality of first V-shaped grooves 7, and dust storage boxes are arranged in the plurality of first V-shaped grooves 7. A first plug hole 12 is opened on the side of the bottom frame 1, and a second plug hole 15 is opened on the side of the outer frame 5. A plurality of plug rods 23 are installed on the side of the outer frame 5, and the first plug hole 12 and the second plug hole 15 cooperate with the plurality of plug rods 23; the filter element is composed of a galvanized sheet mesh, a glass fiber sealing mesh, a glass fiber sealing cotton, a glass fiber separator paper, and a glass fiber filter paper.

[0030] The application of one aspect of this embodiment is: when in use, the bottom frame 1 is fixed by the fixing assembly and the connecting assembly of the plurality of support bars 4, and then the top frame 2 is fixed to the top end of the support bar 4 by the fixing assembly of the top frame 2, and finally the insert rod 23 is inserted into the first insertion hole 12 and the second insertion hole 15, so as to fix the outer frame 5 to the bottom frame 1 and the top frame 2. The structure of quick docking between the top frame 2 and the bottom frame 1 and the support bar 4 is realized by setting the connecting assembly and the fixing assembly in coordination, which not only has the advantages of simple structure, which is conducive to rapid production and cost reduction, but also has the advantages of being very convenient and fast in docking operation, which is conducive to improving the assembly speed of the V-type filter.

[0031] See also Figure 1-4 As shown, the fixing assembly of this embodiment includes a fixing shell 3, a fixing groove 16 is provided at the bottom of the fixing shell 3, sliding grooves 17 are provided on both sides of the fixing groove 16, a trapezoidal slider 18 is slidably fitted in the sliding groove 17, a spring 19 is installed between the trapezoidal slider 18 and the sliding groove 17, a pulling rod 20 is installed on one side of the trapezoidal slider 18, and one end of the pulling rod 20 movably passes through the fixing shell 3; the cross section of the trapezoidal slider 18 is a right-angled trapezoid.

[0032] See also Figure 1-5 As shown, the connection assembly of this embodiment includes an I-shaped connection block 21 installed at both ends of the support bar 4, and a trapezoidal connection block 22 is installed on the side of the I-shaped connection block 21 away from the support bar 4; the cross-section of the trapezoidal connection block 22 is an isosceles trapezoid, which is more convenient for docking operation, and the I-shaped connection block 21 is beneficial to increase the stability of docking.

[0033] By setting the fixing assembly and the connecting assembly, when docking, by inserting the I-shaped connecting block 21 into the fixing groove 16, the inclined surface of the trapezoidal connecting block 22 pushes the inclined surface of the trapezoidal slider 18, so that the trapezoidal slider 18 squeezes the spring 19 to move into the slide groove 17. When the trapezoidal connecting block 22 is inserted into the appropriate position, the trapezoidal connecting block 22 no longer squeezes the trapezoidal slider 18. Under the action of the spring 19, the trapezoidal slider 18 is inserted into the I-shaped connecting block 21, so that the trapezoidal slider 18, the trapezoidal connecting block 22 and the I-shaped connecting block 21 form a tight joint with the fixing groove 16, which is convenient for installation. When disassembly is required, by pulling the pull rod 20, the pull rod 20 drives the trapezoidal slider 18 to squeeze the spring 19 to move into the slide groove 17, thereby facilitating the disassembly of the connecting assembly and helping to improve the disassembly and assembly speed of the V-type filter.
