[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be understood as the usual meanings understood by persons with ordinary skills in the field to which the utility model belongs.

[0022] Embodiment 1

[0023] As Figs. 1 to 3 shown, a dust removal cloth bag convenient to disassemble and assemble comprises a cloth bag 10 and a supporting ring 11 arranged inside the cloth bag 10, a clamping ring 12 arranged outside the cloth bag 10, a protrusion 113 arranged around the circumference of the supporting ring 11 and fixed on the supporting ring 11, a groove 123 arranged around the circumference of the clamping ring 12 and arranged on the clamping ring 12, the protrusion 113 can be engaged with the groove 123 to clamp the cloth bag 10 between the supporting ring 11 and the clamping ring 12, and a clamping mechanism arranged on the supporting ring 11, when the protrusion 113 is engaged with the groove 123, the clamping mechanism further limits the relative position of the cloth bag 10 between the supporting ring 11 and the clamping ring 12.

[0024] The present scheme aims to solve the problems of inconvenient disassembly and assembly of the dust removal cloth bag 10 and insufficient stability after installation. When working, the cloth bag 10 is sleeved on the supporting ring 11, the protrusion 113 of the supporting ring 11 is aligned with the groove 123 of the clamping ring 12 and pushed to engage them, and the cloth bag 10 is preliminarily fixed between the supporting ring 11 and the clamping ring 12. Then the clamping mechanism works to further limit the relative position of the cloth bag 10, preventing it from being displaced due to vibration and the like during equipment operation, greatly improving the convenience of installation and the stability of operation. In actual application, the time cost of installation and maintenance can be significantly reduced, and the production efficiency can be improved. In alternative schemes, the shapes of the protrusion 113 and the groove 123 can be designed as triangles, trapezoids or other shapes according to actual needs, as long as they can achieve good engagement effect; the clamping mechanism can also be replaced by a mechanical buckle or other structures that can play a fastening role, which can also achieve the purpose of the present application.

[0025] In the present embodiment, the clamping mechanism comprises a magnetic extension segment fixed on the supporting ring 11, an opening is arranged on the clamping ring 12, a metal protrusion 121 is arranged in the opening, and a reset mechanism is arranged on the protrusion 121.

[0026] The magnetic strength should be moderate, which can effectively attract the metal protrusion 121, and will not be too strong to cause difficulty in disassembly. The opening size of the clamping ring 12 should be accurately matched with the metal protrusion 121 to ensure that the protrusion 121 can smoothly slide. The spring 122 of the reset mechanism needs to be selected according to the magnetic force of the magnetic extension section and the required clamping force in the actual use scene. When the support ring 11 and the clamping ring 12 are preliminarily engaged through the protrusion 113 and the groove 123, the magnetic extension section is close to the metal protrusion 121, the magnetic attraction makes the protrusion 121 move against the elastic force of the spring 122, further clamping the cloth bag 10, and greatly improving the stability of the cloth bag 10 in operation.

[0027] In this embodiment, the support ring 11 is provided with a slot 112 corresponding to the position of the protrusion 121 and matching in shape.

[0028] The slot 112 on the support ring 11 corresponding to the position of the protrusion 121 and matching in shape needs to be strictly customized according to the size of the protrusion 121 in terms of depth, width and shape, so as to ensure that the protrusion 121 can be tightly embedded and provide reliable clamping effect.

[0029] In this embodiment, the end of the protrusion 121 fixedly connected with the handle is located on one side of the outer wall of the clamping ring 12.

[0030] When disassembling the cloth bag 10, the operator can easily pull out the protrusion 121 from the slot 112 of the support ring 11 by overcoming the magnetic attraction and the elastic force of the spring 122, thereby significantly reducing the disassembly difficulty.

[0031] In this embodiment, the protrusion 113 and the groove 123 are both multiple.

[0032] When installing, multiple protrusions 113 and grooves 123 are engaged at the same time, which disperses the force received by the cloth bag 10, so that the cloth bag 10 is fixed more firmly between the support ring 11 and the clamping ring 12.

[0033] In this embodiment, the reset mechanism includes a stop plate fixedly arranged on the protrusion 121, and a spring 122 fixedly connecting the stop plate and the inner wall of the opening is arranged between the stop plate and the inner wall of the opening; when the extension section of the support ring 11 moves to the vicinity of the protrusion 121, the protrusion 121 can overcome the elastic force of the spring 122 to clamp the cloth bag 10 on the extension section of the support ring 11.

[0034] When the extension section of the support ring 11 moves to the vicinity of the protrusion 121, the magnetic attraction is started, the protrusion 121 moves to clamp the cloth bag 10; when disassembling, external force is applied to the protrusion 121, and the spring 122 pushes the protrusion 121 back to the initial position.

[0035] When the device is in operation, the protective plate protects the magnetic extension and other components from damage. When disassembly is required, the operator pulls the handle at the end of the protrusion 121 to make the protrusion 121 overcome the magnetic attraction and the spring force of the spring 122 and pull out of the slot 112, thereby releasing the clamping state. Then, the protrusion 113 and the groove 123 on the support ring 11 and the clamping ring 12 are separated, and the bag 10 can be conveniently removed for maintenance or replacement. The whole process is simple and efficient.

[0036] Embodiment 2

[0037] In this embodiment, the support ring 11 is also provided with a protective plate on the extension.

[0038] The protective plate can prevent the magnetic extension from being damaged by collision, scratching, etc., and prolong the service life of the clamping mechanism.

[0039] In this embodiment, the protrusion 121 is cylindrical, and the length axis of the protrusion 121 is perpendicular to the length axis of the support ring 11.

[0040] The protrusion 121 is designed to be cylindrical and the length axis is perpendicular to the length axis of the support ring 11. This shape makes the protrusion 121 move in the opening with small resistance and high flexibility, and the cooperation precision with the slot 112 on the support ring 11 is high.

[0041] The detachable dust cloth bag 10 device has multiple significant beneficial effects in practical scenarios. In terms of installation, the engagement design of the support ring 11 and the clamping ring 12 through the protrusions 113 and the grooves 123 greatly simplifies the installation process, reduces the installation difficulty, significantly shortens the installation time, and improves the installation efficiency. The setting of the clamping mechanism effectively enhances the stability of the cloth bag 10 after installation. Whether in a vibration environment in industrial production or under the impact of high-speed airflow, the cloth bag 10 can be firmly in place, reducing the risk of reduced dust removal efficiency caused by displacement. When disassembling, the design of the handle and the alternative flexible clamping method make it easy for maintenance personnel to operate, significantly reducing maintenance costs and equipment downtime. At the same time, multiple protrusions 113 and grooves 123 and multiple adjustable structural designs make it suitable for cloth bags 10 of different sizes and complex working conditions, with wide applicability, effectively improving overall production efficiency and environmental protection effect.

[0042] The above examples are only used to illustrate the technical solutions of the present disclosure, not to limit it; although the present disclosure has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacements for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
