For example, in applications requiring intermittent clamping, pushing, or lifting actions, and in equipment with specific requirements for cylinder installation space, operating speed, and output force, non-standard single-acting normally-entry cylinders leverage their customization advantages to provide precise and reliable power drive. However, because cylinders are used in various environments, high humidity, corrosive environments, and dusty or particulate environments can easily damage the piston rod surface, reducing its lifespan and making it unsuitable for use in different environments. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a novel non-standard single-acting constant-entry cylinder. A rectangular protective sleeve covers the piston rod, reducing contact between external dust and the piston rod. The sleeve moves continuously with the piston rod, providing constant protection and adapting to various environments. When the sleeve is retracted, it contacts a cleaning brush, reducing surface dust and minimizing friction through rolling instead of sliding, thus reducing the impact of dust on the sleeve. This provides long-term dust containment, enabling use in diverse environments. It solves the problem that high humidity, corrosive environments, and dusty or particulate environments can easily damage the piston rod surface, reducing its lifespan and making it unusable in various conditions.

The cleaning brush cylinders are in contact with the rectangular protective sleeve. Rotating shafts are fixedly arranged at both ends of the cleaning brush cylinders. Ball bearings are arranged above and below the piston rod. A rectangular support is fixedly arranged on the outer side of the cylinder housing. The rectangular support is in contact with the rectangular protective sleeve.

[0006] Preferably, the number of the grooves is two. The two grooves are symmetrically arranged about the central axis in the horizontal direction of the cylinder housing. A cylindrical protective shell is arranged on the outer side of the cylinder housing.

[0007] Preferably, the cross-sectional shape of the annular plate is in the shape of a "square". The number of the moving blocks is two. The two moving blocks are both fixedly connected with the annular plate.

[0014] The utility model provides a novel non-standard single-acting normally-engaged cylinder. Compared with the prior art, the following advantageous effects are achieved:

[0015] 1. This new type of non-standard single-acting constant-entry cylinder uses a rectangular protective sleeve to cover the piston rod, which reduces the contact between external dust and the piston rod. The rectangular protective sleeve moves with the piston rod, always protecting it. It can adapt to different environments, and when the rectangular protective sleeve is retracted, it can come into contact with the cleaning brush. The cleaning brush reduces surface dust, and the rolling action instead of sliding reduces friction, minimizing the impact of dust on the rectangular protective sleeve. It can block dust for a long time, thus enabling use in different environments.

[0016] 2.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and 3-4, the present utility model provides a technical solution: a novel non-standard single-acting always-engaging cylinder, including a cylinder housing 1 and a piston rod 2. Grooves 3 are provided on both the top and bottom surfaces of the cylinder housing 1. A connecting spring 4 is provided inside the groove 3. On one side of the connecting spring 4, there is a moving block 5, and the moving block 5 is slidably connected to the groove 3.

[0024] One end of the piston rod 2 away from the cylinder housing 1 is fixedly provided with a fixing plate 6. On one side of the fixing plate 6, there is a rectangular protective sleeve 7. The rectangular protective sleeve 7 is in contact with the cylinder housing 1. An annular plate 8 is provided on the outer side of the cylinder housing 1 near the moving block 5. The annular plate 8 is fixedly connected to the rectangular protective sleeve 7. Cleaning brush cylinders 9 are provided around the rectangular protective sleeve 7. The cleaning brush cylinders 9 are in contact with the rectangular protective sleeve 7. Rotating shafts 10 are fixedly provided at both ends of the cleaning brush cylinders 9. Ball bearings 11 are provided above and below the piston rod 2. A rectangular support 12 is fixedly provided on the outer side of the cylinder housing 1. The rectangular support 12 is in contact with the rectangular protective sleeve 7.

[0025] The cross-sectional shape of the annular plate 8 is a "mouth" shape. The number of grooves 3 is two. The two grooves 3 are symmetrically arranged about the central axis in the horizontal direction of the cylinder housing 1. A cylindrical protective shell is provided on the outer side of the cylinder housing 1, and the cylindrical protective shell is made of corrosion-resistant material, which can reduce impurities or dust from falling on the rectangular protective sleeve 7. The number of moving blocks 5 is two, and both of the two moving blocks 5 are fixedly connected to the annular plate 8. During the movement of the rectangular protective sleeve 7, the annular plate 8 can move, and the moving block 5 fixedly connected to the annular plate 8 moves simultaneously. Since the moving block 5 is in the groove 3, the moving block 5 can move along the groove 3 and squeeze the connecting spring 4 in the groove 3, causing the connecting spring 4 to deform.

[0026] The number of support rods 17 is four. The cross-sectional shape of each support rod's 17 is U-shaped. A cylinder 18 is provided on the outer side of the middle part of each support rod 17, and the cylinder 18 is rotatably connected to the support rod 17. The cylinder 18 is in contact with the rectangular protective sleeve 7. The cylinder 18 rotates around the support rod 17.

[0027] Please refer to Figure 1-2The cleaning brush 9 has adjusting rods 13 at both ends. The rotating shaft 10 passes through the adjusting rods 13 and is rotatably connected to them. A guide rod 14 is provided at the end of the adjusting rod 13 away from the rotating shaft 10. The guide rod 14 is slidably connected to the adjusting rod 13. A compression spring 4 is provided on the outside of the guide rod 14. A positioning frame 15 is provided at the end of the guide rod 14 away from the adjusting rod 13. A connecting plate 16 is fixedly provided on one side of the cylinder housing 1. The positioning frame 15 is fixedly connected to the cylinder housing 1 through the connecting plate 16. Support rods 17 are fixedly provided around the inner wall of the connecting plate 16. The rotation of the cleaning brush 9 causes the rotating shaft 10 to rotate. The adjusting rod 13 is slidably connected to the guide rod 14. The movement of the adjusting rod 13 can compress the compression spring. The compression spring will automatically adjust the pressure according to the surface condition of the rectangular protective sleeve 7 to ensure that the bristles are in full contact with the surface of the rectangular protective sleeve 7, while not increasing the frictional resistance due to excessive pressure.

[0028] During operation, the movement of piston rod 2 increases the overall length. As piston rod 2 moves, the fixed plate 6, which is fixedly connected to piston rod 2, moves simultaneously, causing the rectangular protective sleeve 7 to move along with piston rod 2. The rectangular protective sleeve 7 covers piston rod 2, reducing contact between external dust and piston rod 2, preventing dust from entering the cylinder housing 1 during piston rod retraction and thus preventing any impact on the gas inside the housing. Because the rectangular bracket 12 contacts the inner wall of the rectangular protective sleeve 7, it supports the rectangular protective sleeve 7, reducing the contact area between the rectangular protective sleeve 7 and the cylinder housing 1. The rectangular protective sleeve 7 also contacts the ball bearings 11, reducing friction and allowing the cylinder 18 to... Rotating around the support rod 17 reduces friction and wear on the rectangular protective sleeve 7 during its movement. When the piston rod 2 retracts, it allows the rectangular protective sleeve 7 to come into contact with the cleaning brush cylinder 9, enabling the cleaning brush cylinder 9 to rotate and clean the rectangular protective sleeve 7. Rolling instead of sliding reduces friction and dust accumulation on the surface of the rectangular protective sleeve 7. An adjusting rod 13 is installed on the cleaning brush cylinder 9 and is slidably connected to the guide rod 14. The movement of the adjusting rod 13 compresses the compression spring, which automatically adjusts the pressure according to the surface condition of the rectangular protective sleeve 7, ensuring full contact between the bristles and the surface of the rectangular protective sleeve 7 without increasing frictional resistance due to excessive pressure.
