Description

Technical Field

[0001] This utility model relates to the field of protection technology for pneumatic power mechanical components, specifically to a dust protection device for pneumatic power mechanical components. Background Technology

[0002] Pneumatic power mechanical components refer to mechanical components that use air pressure as a power source. Common pneumatic power mechanical components include cylinders, pneumatic valves, and pneumatic drive devices.

[0003] Pneumatic power mechanical components are widely used in mechanical equipment, and there are many types. Cylinders are widely used in mechanical equipment, and the operating environment is not fixed. Therefore, in some special mechanical equipment and special environments, such as areas with high dust levels or where the products being produced have a certain degree of corrosiveness, the cylinder's telescopic arm may corrode. Traditional protection often involves setting up a protective plate on the top of the cylinder for shielding. However, for highly corrosive environments, the protective plate on the top cannot completely protect the cylinder. As a result, dust can enter the cylinder during actual use, obstructing the cylinder's extension and contraction or causing corrosion, thus affecting the cylinder's service life and failing to meet the usage requirements. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a dust protection device for pneumatic power mechanical components.

[0028] Example

[0029] The dust protection device for pneumatic power mechanical components provided in this embodiment, such as Figures 1-7 As shown, the device includes a mounting housing 1, a mounting plate 4 on the rear side of the mounting housing 1, a cylinder 2 on the front side of the mounting plate 4 and inside the mounting housing 1, a dustproof protection mechanism 3 inside the mounting housing 1, and two through cavities 8 on the upper part of the interior of the mounting plate 4. The mounting plate 4 is used to install the cylinder 2 and seal the rear side of the mounting housing 1 to prevent external dust or corrosive substances from entering through the rear side of the mounting housing 1 and causing corrosion damage to the cylinder 2. The through cavities 8 are used to guide the air guide tube of the cylinder 2 into the interior of the mounting housing 1 and connect it to the cylinder 2. The dustproof protection mechanism 3 is used to protect the output shaft of the cylinder 2 when it extends to prevent dust and corrosive substances from damaging the output shaft of the cylinder 2, affecting subsequent use and reducing the service life of the cylinder 2.

[0030] The dust protection mechanism 3 includes a storage slot 304 inside the housing 1 and a protective cover 301 inserted inside the storage slot 304. The output shaft of the cylinder 2 passes through the protective cover 301 and extends to the left side of the protective cover 301. The storage slot 304 is used to accommodate the protective cover 301, so that the protective cover 301 can move with the output shaft of the cylinder 2, thereby protecting the output shaft of the cylinder 2.

[0031] The output shaft of cylinder 2 is threaded with two nuts 302, which are located on the inner and outer sides of the protective cover 301 respectively. The two nuts 302 are used to fix the protective cover 301 relative to the output shaft of cylinder 2, thereby enabling the protective cover 301 to move with the output shaft of cylinder 2.

[0032] Four guide grooves 303 are provided inside the housing shell 1 and on the inner side of the storage slot 304. A guide rod 305 is slidably connected inside the guide groove 303. One side of the guide rod 305 is fixedly connected to the inner cavity of the protective cover 301. The guide grooves 303 and the guide rod 305 are used to stabilize the protective cover 301 and prevent the protective cover 301 from shaking when it moves.

[0033] A groove 6 is provided on the rear side of the mounting storage shell 1. The mounting plate 4 passes through the groove 6 into the interior of the mounting storage shell 1. The groove 6 is designed to insert the mounting plate 4 into the interior of the mounting storage shell 1, thereby reducing space usage.

[0034] The mounting plate 4 has four mounting slots 12 inside. A first bolt 7 is inserted into the mounting slot 12. One side of the first bolt 7 passes through the interior of the mounting housing 1 and is threadedly connected to the mounting housing 1. The mounting slots 12 are designed to accommodate the first bolt 7, so that the first bolt 7 passes through the interior of the mounting plate 4 and is not exposed on the outside of the mounting plate 4, which would affect the connection between the whole and the equipment.

[0035] A movable hinge 5 is provided on the rear side of the mounting plate 4. Four second bolts 9 are inserted inside the movable hinge 5. One side of the second bolts 9 passes through the interior of the mounting plate 4 and is threadedly connected to the mounting plate 4. When the cylinder 2 is in use, it may push the equipment to tilt, which requires the cylinder 2 to rotate with the equipment. The movable hinge 5 is used to connect the whole to the equipment and enable the whole to rotate with the equipment to meet different usage needs.

[0036] Two mounting blocks 11 are fixedly installed on both the left and right sides of the cylinder 2. A third bolt 10 is inserted inside the mounting block 11. One side of the third bolt 10 passes through the interior of the mounting plate 4 and is threadedly connected to the mounting plate 4. The cylinder 2 is installed inside the mounting plate 4 by the setting of the third bolt 10 and the mounting block 11.

[0037] To further ensure the dustproof effect, a sealing ring is added at the contact point between the protective cover 301 and the storage groove 304, and a dustproof sealing ring is added at the inlet of the passage cavity 8 to improve the overall dustproof performance.

[0038] In use, cylinder 2 is fixed to the front of mounting plate 4 using third bolt 10 and mounting block 11. The air guide pipe for driving cylinder 2 passes through cavity 8 to the front of mounting plate 4 and connects to cylinder 2. After connection, mounting plate 4 and cylinder 2 are inserted into the interior of mounting housing 1, with mounting plate 4 extending into groove 6. First bolt 7 is inserted into mounting slot 12 to fix mounting plate 4 to mounting housing 1, thus fixing mounting housing 1 inside. A single nut 302 is threaded onto the outside of cylinder 2's output shaft. Protective cover 301 is inserted into housing slot 304, while guide rod 305 extends into guide slot 303, simultaneously causing cylinder 2 to... The output shaft of the cylinder 2 extends to the front of the protective cover 301. Another nut 302 is threaded onto the outside of the output shaft of the cylinder 2 and located on the outside of the protective cover 301, thereby connecting the output shaft of the cylinder 2 to the mounting housing 1. After the connection is completed, depending on the usage requirements of the cylinder 2, if it needs to rotate with the equipment, the movable hinge 5 is installed to the rear of the mounting plate 4 through the second bolt 9, and connected to the equipment through the movable hinge 5. If it does not need to rotate, the movable hinge 5 does not need to be installed, and the mounting plate 4 can be directly connected to the equipment through the second bolt 9. In use, since the protective cover 301 is connected to the output shaft of the cylinder 2 through the nut 302, when the output shaft of the cylinder 2 extends, it drives the protective cover 301 to extend, thereby protecting the output shaft of the cylinder 2.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
