Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, specifically to a self-contained cylinder that does not interfere with each other. Background Technology

[0002] A cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy. With its simple structure, rapid response, low cost, and strong environmental adaptability, it has been widely used in industrial automation and many other fields.

[0003] A cylinder is mainly composed of basic components such as a cylinder barrel, end caps, and piston rod. The cylinder barrel, the main body of the cylinder, is usually a hollow cylindrical metal tube, commonly made of materials such as aluminum alloy, stainless steel, and carbon steel. The inner wall is precision machined, such as honing or grinding, to ensure smoothness and dimensional accuracy. There are usually two end caps, fixed at both ends of the cylinder barrel. They are usually made of the same material as the cylinder barrel and have air inlet or outlet ports, piston rod guide holes, buffer adjustment devices, and mounting threaded holes. The piston rod is a rigid metal rod, usually made of high-strength steel or stainless steel. One end is fixed to the center of the piston, and the other end extends to the outside of the cylinder through the guide hole of the end cap.

[0004] With the advancement of technology, pneumatic products require cylinders to be miniaturized and lightweight, and to meet the requirements of complex working conditions in a small space. Therefore, a cylinder with independent movement was designed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cylinder that does not interfere with each other, so as to solve the technical problem of poor performance of traditional cylinders.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-contained, non-interfering cylinder, comprising a main body, with independent cylinders arranged on both sides of the main body. A piston rod is slidably passed through one end of each side of the main body and is located within the corresponding independent cylinder. Each piston rod has a sealing ring installed at its end within the corresponding independent cylinder, which slidably seals against the inner wall of the corresponding independent cylinder. Both sides of the main body have forward and backward air holes communicating with the corresponding independent cylinders. Each backward air hole is located near the end extending outward from the corresponding piston rod and cooperates with the corresponding sealing ring. Each forward air hole is located away from the end extending outward from the corresponding piston rod and cooperates with the corresponding sealing ring.

[0007] By adopting the above technical solution, gas is injected into the corresponding independent cylinder through the corresponding forward air port, thereby pushing the piston rod on the corresponding sealing ring forward. Similarly, gas is injected into the corresponding independent cylinder through the corresponding backward air port, pushing the piston rod on the corresponding sealing ring backward. This completes the independent movement of the piston rods in the two sets of independent cylinders within the main body, forming a "same body" structure. Compared with two cylinders arranged side by side, it occupies less space. Furthermore, the piston rods on both sides are located in their respective independent cylinders, and the air passages and sealing rings are completely isolated. Even if one side loses pressure or is loaded, the other side can still operate normally, solving the problem of cross-flow and movement interference caused by the shared end caps or air passages of traditional parallel cylinders.

[0008] The present invention is further configured such that each of the forward air hole and the reverse air hole is provided with a thread.

[0009] By adopting the above technical solution, the threaded interface allows the connector or speed control valve to be directly connected and fixed to the inlet and outlet air ports, saving the space required for welding or additional adapters in traditional cylinders.

[0010] The present invention is further provided that the main body has a fixing hole.

[0011] By adopting the above technical solution, fixing holes can be directly opened on the main body, eliminating the need for an additional base plate and further reducing the space occupied by the device.

[0012] In summary, the present invention has the following main advantages: This invention forms a "same-body" structure by independently moving the piston rods in two sets of independent cylinders. Compared with two cylinders arranged side by side, it occupies less space. Furthermore, the piston rods on both sides are located in their respective independent cylinders, and the air passages and sealing rings are completely isolated. Even if one side loses pressure or is loaded, the other side can still operate normally. This solves the problem of air leakage and operation interference caused by the shared end caps or air passages of traditional parallel cylinders. In addition, the threaded design at the inlet and outlet air ports and the fixing holes opened on the main body reduce some unnecessary structures and further reduce the space occupied by the device.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] The cylinders of the same body do not interfere with each other, such as Figure 1-5 As shown, the device includes a main body 1, with independent cylinders 2 on both sides of the main body 1. A piston rod 3, located within the corresponding independent cylinder 2, is slidably passed through one end of each side of the main body 1. Each piston rod 3 has a sealing ring 4 installed at its end within the corresponding independent cylinder 2, which slidably seals against the inner wall of the cylinder 2. Both sides of the main body 1 have forward air holes 5 and backward air holes 6 communicating with the corresponding independent cylinders 2. Each backward air hole 6 is located near the end of the piston rod 3 extending outward and cooperates with the corresponding sealing ring 4. Each forward air hole 5 is located away from the end of the piston rod 3 extending outward and cooperates with the corresponding sealing ring 4. Gas passes through the corresponding... The forward air port 5 fills the corresponding independent cylinder 2, thereby pushing the piston rod 3 on the corresponding sealing ring 4 forward. Similarly, the gas is filled into the corresponding independent cylinder 2 through the corresponding backward air port 6, pushing the piston rod 3 on the corresponding sealing ring 4 backward. This completes the independent movement of the piston rod 3 in the two sets of independent cylinders 2 in the main body 1, forming a "same body" structure. Compared with the two cylinders arranged side by side, it occupies less space. Moreover, the piston rods 3 on both sides are located in their respective independent cylinders 2, and the air passages and sealing rings 4 are completely isolated. Even if one side loses pressure or is loaded, the other side can still operate normally. This solves the problem of air leakage and movement interference caused by the shared end caps or air passages of traditional parallel cylinders.

[0018] During this period, such as Figure 1-5 As shown, each inlet air port 5 and outlet air port 6 is threaded. The threaded interface allows the connector or speed control valve to be directly connected and fixed to the inlet air port 5 and outlet air port 6, saving the space required for welding or additional adapters in traditional cylinders.

[0019] In addition, such as Figure 1-5 As shown, the main body 1 has a fixing hole 7. The fixing hole 7 is directly opened on the main body 1, eliminating the need for an additional base plate and further reducing the space occupied by the device.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
