Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a snap-on dust bag quick-release structure. Background Technology

[0002] Dust bags are bags used to prevent the intrusion of external pollutants such as dust and dirt. They are usually made of special materials and have sealing and dustproof functions, which can effectively protect the internal items from the influence of the external environment. In the application of dustproof equipment, the installation structure of dust bags and external frames directly affects the efficiency of equipment use and the convenience of maintenance. Traditional dust bag installation methods mostly rely on fixing methods such as bolts and ropes.

[0003] The application for a dust collector bag with moisture-proof function, filed with application number 202421326474.0, proposes to provide a fastening component on the side of the connecting ring, which makes the top of the bag body more securely connected to the connecting ring. This prevents the dust collector bag from coming loose during use, ensuring smooth use of the dust collector bag. It also facilitates the disassembly, maintenance, and replacement of the dust collector bag by subsequent staff. Furthermore, the structure is simple and easy for staff to use.

[0004] While existing dust bag connection structures meet user needs to a certain extent, they still have certain shortcomings. Specifically, the installation process is cumbersome, requiring tools to operate each bag individually, consuming considerable manpower and time. This inefficiency is particularly pronounced in large-scale equipment or scenarios involving frequent dust bag replacements. Furthermore, disassembly also requires gradually disassembling the fixing components, which is not only complex but may also lead to insecure installation upon subsequent use due to component wear. Therefore, this invention designs a snap-on quick-install structure for dust bags to solve these problems. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1-5As shown, this utility model provides a technical solution: a snap-on dust bag quick-installation structure, including an outer frame 1 and a dust bag 2. Limiting posts 3 are uniformly fixedly installed on the top of the dust bag 2. Limiting grooves are opened on the outer frame 1 at the corresponding positions of the limiting posts 3. A rubber cylinder 4 is glued inside the limiting groove. Spring telescopic posts 5 are uniformly installed on the ends of the outer frame 1 by screws. An insert block 6 is installed on one end of the spring telescopic post 5 by screws. A corresponding groove 7 is opened on the limiting post 3 at the corresponding position of the insert block 6. A sealing cylinder 8 is rotatably connected to the bottom outer side of the outer frame 1. The insert block 6 and the sealing cylinder 8 are connected by a connecting rod 9. A rubber plate 10 is glued inside the sealing cylinder 8. A moving rod 11 is slidably connected inside one of the connecting rods 9. A positioning groove 12 is opened on the outer frame 1 at the corresponding position of the moving rod 11. A magnetic ring 13 is installed on the top of the connecting rod 9 by screws. The magnetic ring 13 and the moving rod 11 are attracted to each other.

[0026] The top of the limiting post 3 has a rounded corner. The limiting post 3 is located inside the rubber cylinder 4, which increases the friction between the limiting post 3 and the outer frame 1, so as to initially fix the dust bag 2 and facilitate the movement of the limiting post 3 into the rubber cylinder 4.

[0027] The end of the insert 6 is provided with an inclined angle to facilitate moving the insert 6 into the corresponding slot 7.

[0028] The rubber sheet 10 is located between the outer frame 1 and the dust bag 2, which improves the sealing between the outer frame 1 and the dust bag 2 and avoids dust leakage between the outer frame 1 and the dust bag 2.

[0029] Limit frames are welded to the top and middle of the moving rod 11, and the bottom of the moving rod 11 is inside the positioning groove 12, which facilitates the positioning of the moving rod 11 and avoids the problem of the moving rod 11 falling out of the connecting rod 9.

[0030] Personnel move the dust bag 2 to move the limiting post 3 into the outer frame 1. At this time, the limiting post 3 first pushes the insert block 6. When the insert block 6 moves to the corresponding slot 7, the spring telescopic post 5 stretches and pushes the insert block 6 to move into the corresponding slot 7, realizing the movement of the limiting post 3 and fixing the dust bag 2. This can quickly fix the dust bag 2. After the insert block 6 moves into the corresponding slot 7, the moving rod 11 falls into the positioning slot 12 due to gravity, causing the moving rod 11 to attract the magnetic ring 13 and limit the connection rod 9. To prevent the connecting rod 9 from becoming loose after the outer frame 1 and the dust bag 2 are connected, when personnel need to disassemble the dust bag 2, they move the moving rod 11 out of the positioning groove 12, and then rotate the sealing cylinder 8. The rotation of the sealing cylinder 8 drives the connecting rod 9 to rotate, which in turn drives multiple insert blocks 6 to move out of their corresponding grooves 7. Then, personnel can disassemble the dust bag 2 by moving it, which facilitates the disassembly of the dust bag 2 and improves the convenience of its installation and disassembly.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
