Description

Technical Field

[0001] The utility model discloses a dust collector which is easy to assemble with dust removal bags and belongs to the technical field of bag dust collectors. Background Art

[0002] The bag filter needs to use dust bags. As the key component in the operation of the dust collector, the dust bag is usually a cylindrical filter bag hung vertically in the dust collector. It has the effects of high-efficiency filtration, easy dust removal and durability. The existing dust bag needs to use a keel to support the bag, which is convenient for installation inside the dust collector. It has the advantages of being strong and not easy to break, and having a good supporting effect.

[0003] After searching the Chinese patent number: CN216878331U, a bag dust collector with an easily detachable keel is found. This design scheme can realize the detachment or connection of the annular frame and the fixed plate by pressing the plug block, which is convenient for replacing the keel. However, this design scheme only limits the fixed plate by the plug block. If the plug block is accidentally touched by an external object, the internal spring is easily compressed, causing the fixed plate to fall off from the annular frame and the dust bag to fall off. Now, a dust collector that is easy to assemble with a dust bag is urgently needed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a dust collector that is easy to assemble with dust bags, so as to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure. The design limits the fixing plate by the mounting plate. When foreign objects accidentally touch the mounting plate, it is fixed by the fastening bolts and will not shake, which can prevent the fixing plate from falling off the annular frame.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a dust collector that is easy to assemble with a dust bag, comprising an annular frame, a mounting plate, a fastening bolt, a first return spring, a second movable groove, a second return spring, a threaded hole and a first movable groove, the inner wall of the annular frame is fittedly connected with a fixing plate, a through hole is provided inside the fixing plate, a second movable groove is provided inside the fixing plate, the second movable groove is movably connected with a movable limiting block, and a second return spring is fixed between the movable limiting block and the second movable groove;

[0006] A first movable groove is provided inside the movable limit block, a slider is movably connected to the first movable groove, a first return spring is fixed between the slider and the first movable groove, mounting plates are fixed to the left and right end surfaces of the slider, threaded holes are provided inside the mounting plate and the annular frame, and fastening bolts are threadedly connected to the threaded holes.

[0007] Furthermore, the through holes are provided in a plurality of groups, and the sizes of the through holes in the plurality of groups are equal and they are symmetrically arranged inside the fixing plate.

[0008] Furthermore, the specification of the second movable groove matches the specification of the movable limit block, and the two can fit and slide in connection.

[0009] Furthermore, the specification of the first movable groove matches the specification of the sliding block, and the two can fit and slide in connection.

[0010] Furthermore, the inner diameter of the threaded hole is equal to the outer diameter of the fastening bolt, and the two can fit together for threaded connection, and the inner side surface of the mounting plate is configured as an arc-shaped structure.

[0011] Furthermore, the first movable groove, the slider, the first return spring and the mounting plate constitute a limiting assembly, and the limiting assembly is provided in two groups. The two groups of limiting assemblies have the same composition structure and are symmetrically arranged inside the movable limiting block.

[0012] The beneficial effects of the utility model: the utility model is a dust collector which is easy to assemble with a dust bag. Since the utility model adds a mounting plate, a fastening bolt, a first return spring, a second movable groove, a second return spring, a threaded hole and a first movable groove, the design limits the fixed plate by the mounting plate. When an external object accidentally touches the mounting plate, the fastening bolts fix the connection therewith and will not shake, and the fixed plate can be prevented from falling off the annular frame. This solves the problem that the original bag dust collector uses an easily detachable keel to limit the fixed plate only by an insert block. If an external object accidentally touches the insert block, the internal spring is easily compressed, thereby causing the fixed plate to fall off the annular frame and the dust bag to fall off.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a dust collector that is easy to assemble with dust removal bags, including an annular frame 1, a mounting plate 5, a fastening bolt 6, a first return spring 7, a second movable groove 8, a second return spring 9, a threaded hole 10 and a first movable groove 12, the inner wall of the annular frame 1 is fitted with a fixing plate 2, a through hole 3 is opened inside the fixing plate 2, a second movable groove 8 is opened inside the fixing plate 2, the second movable groove 8 is movably connected with a movable limit block 4, and a second return spring 9 is fixed between the movable limit block 4 and the second movable groove 8;

[0021] A first movable groove 12 is provided inside the movable limit block 4, and a slider 11 is movably connected to the first movable groove 12. A first return spring 7 is fixed between the slider 11 and the first movable groove 12. Mounting plates 5 are fixed to the left and right end surfaces of the slider 11. Threaded holes 10 are provided inside the mounting plate 5 and the annular frame 1. The threaded holes 10 are threadedly connected with fastening bolts 6. This design limits the fixing plate 2 through the mounting plate 5. When an external object accidentally touches the mounting plate 5, it is fixedly connected by the fastening bolts 6 and will not shake, thereby preventing the fixing plate 2 from falling off the annular frame 1.

[0022] As a first embodiment of the utility model: multiple groups of through holes 3 are provided, and the multiple groups of through holes 3 are equal in size and symmetrically opened inside the fixed plate 2. This design facilitates the installation of the annular frame 1 inside the dust collector through the multiple groups of through holes 3;

[0023] The specification of the second movable groove 8 matches that of the movable limit block 4, and the two can be fitted and slidably connected. The design enables the movable limit block 4 to move into the fixed plate 2 through the fitting and sliding connection between the movable limit block 4 and the second movable groove 8. The specification of the first movable groove 12 matches that of the slider 11, and the two can be fitted and slidably connected. The design enables the slider 11 to move into the movable limit block 4 through the fitting and sliding connection between the slider 11 and the first movable groove 12.

[0024] The inner diameter of the threaded hole 10 is equal to the outer diameter of the fastening bolt 6, and the two can be threadedly connected in a snug fit. The inner side surface of the mounting plate 5 is set to an arc-shaped structure. After the inner side surface of the mounting plate 5 is snugly connected to the outer wall of the annular frame 1, the mounting plate 5 can be installed on the outer side of the annular surface of the annular frame 1 through the snug threaded connection between the fastening bolt 6 and the threaded hole 10;

[0025] The first movable groove 12, the slider 11, the first return spring 7 and the mounting plate 5 constitute a limiting assembly. There are two groups of limiting assemblies. The two groups of limiting assemblies have the same composition structure and are symmetrically arranged inside the movable limiting block 4. This design uses two groups of limiting assemblies to prevent the movable limiting block 4 from moving in the second movable groove 8, so that it will not shake after being touched by the outside, thereby preventing the dust bag from falling.

[0026] As a second embodiment of the present utility model: when the staff needs to install the plate 5, first push the installing plate 5 into the movable limit block 4, so that the sliding block 11 is fitted and slidably connected with the first movable groove 12. At this time, the installing plate 5 shrinks into the first movable groove 12, and then pushes the movable limit block 4 into the second movable groove 8, so that the movable limit block 4 shrinks into the second movable groove 8 (at this time, the first return spring 7 and the second return spring 9 are both compressed). At this time, the outer wall of the fixed plate 2 is fitted and clamped on the inner wall of the annular frame 1. At this time, the second return spring 9 rebounds to make the movable limit block 4 extend out of the annular frame 1. Then the first return spring 7 rebounds to make the installing plate 5 extend out of the movable limit block 4. Through the fitting threaded connection of the fastening bolt 6 and the threaded hole 10, the installing plate 5 can be installed on the outer side of the annular surface of the annular frame 1, so that the movable limit block 4 cannot move in the second movable groove 8, so that it will not shake after being touched by the outside, thereby preventing the dust bag from falling.
