Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, specifically to a high-sealing stainless steel mini cylinder. Background Technology

[0002] A cylinder is a cylindrical metal component that guides a piston in a linear reciprocating motion within the cylinder. In an engine cylinder, air expands, converting thermal energy into mechanical energy; in a compressor cylinder, gas is compressed by the piston, increasing its pressure. Pneumatic actuators convert the pressure energy of compressed gas into mechanical energy. Cylinders come in two types: those that perform reciprocating linear motion and those that perform reciprocating oscillating motion.

[0003] However, in the existing technology, the stroke of the miniature cylinder is relatively short, which means that the cylinder head will be frequently impacted during the use of the prototype, resulting in large wear and tear on the cylinder head and failure. In addition, the moving rod inside the cylinder will often rub against the cylinder head, causing gaps and air leakage. Summary of the Invention

[0004] The purpose of this utility model is to provide a high-sealing stainless steel mini cylinder, which has the advantages of protecting the inside of the mini cylinder, preventing damage to the internal hard contact caused by the short stroke of the mini cylinder, and sealing the mini cylinder to prevent air leakage and the entry of dust and impurities, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-sealing stainless steel mini cylinder, comprising a housing assembly and a piston assembly, wherein the piston assembly is disposed within the housing assembly for moving within the housing assembly.

[0006] Furthermore, the piston assembly includes a moving rod, a connecting rod, a first nut, a second nut, a mounting block, a crash plate, two sealing rings, a dustproof plate, and a retaining ring. The moving rod is disposed within the outer casing assembly. The connecting rod is fixedly mounted on one end of the moving rod. The second nut is threaded onto the connecting rod and the moving rod. The mounting block is slidably fitted onto the connecting rod. The crash plate is fixedly mounted on one outer wall of the mounting block. Both sealing rings are fitted onto the mounting block. The dustproof plate is disposed within the outer casing assembly, and the retaining ring is disposed within the outer casing assembly.

[0007] Furthermore, two grooves are formed on the outer wall of the mounting block, and the two grooves are adapted to two sealing rings.

[0008] Furthermore, the two sealing rings are Y-shaped and arranged opposite each other.

[0009] Furthermore, the dustproof plate is made of rubber and is ring-shaped.

[0010] Furthermore, the outer casing assembly includes a front cover, a sleeve, a rear cover, a circular groove, an air outlet, and an air inlet. The sleeve is fitted onto the front cover, the rear cover is inserted into the sleeve, the circular groove is formed on one outer wall of the front cover, the air outlet is formed on the outer wall of the front cover and communicates with the circular groove, the air inlet is formed on the rear cover, the movable rod is slidably mounted on the front cover, the sleeve is adapted to the mounting block, the dustproof plate is fixedly mounted on the inner wall of the circular groove, and the retaining ring is fixedly mounted on the inner wall of the circular groove.

[0011] Furthermore, a rubber ring is fitted on the front cover, a rubber ring is fitted on the rear cover, and the sleeve is made of stainless steel.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This utility model, through the setting of a shell assembly, allows the mounting block to drive the sealing ring to move during the piston movement of the installation and movement. The sealing ring is made of rubber and has good elasticity, filling the gap between the mounting block and the sleeve, preventing injected gas from escaping from the gap and causing insufficient thrust. When the mounting block moves to fit against the front cover, a collision plate acts as a barrier. Because the collision plate is made of rubber, it prevents the mounting block from colliding with the front cover and causing deformation and damage. A dustproof plate seals the gap between the front cover and the moving rod, preventing friction and wear between the moving rod and the front cover during movement, and preventing dust and impurities from entering the sleeve through the gap. It has the advantages of protecting the inside of the mini cylinder, preventing damage caused by hard contact due to the short stroke of the mini cylinder, and sealing the mini cylinder to prevent air leakage and the entry of dust and impurities.

[0014] This invention features a piston assembly. An external air pipe is removed and aligned with the air outlet and inlet. The external air pipe is then inserted into the air outlet and inlet. Air is injected through the external air source box into the air pipe, entering the inlet through the air pipe. The inlet guides the gas into the sleeve, pushing the mounting block within the sleeve. The mounting block drives the moving rod in piston-like motion. As the mounting block moves, it pushes the existing gas within the sleeve, causing it to exit through the air outlet. If miniature cylinder retraction is required, gas is injected into the air outlet. This design offers the advantage of convenient connection to an air source for gas injection and propulsion.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides, for example Figures 1-5 As shown, a high-sealing stainless steel mini cylinder includes a housing assembly 1 and a piston assembly 2, the piston assembly 2 being disposed within the housing assembly 1 for movement within the housing assembly 1.

[0023] Additionally, the piston assembly 2 includes a moving rod 201, a connecting rod 202, a first nut 203, a second nut 204, a mounting block 205, a crash plate 206, two sealing rings 207, a dustproof plate 208, and a retaining ring 209. The moving rod 201 is disposed inside the outer casing assembly 1. The connecting rod 202 is fixedly mounted on one end of the moving rod 201. The second nut 203 is threaded onto the connecting rod 202, and the second nut 204 is threaded onto the moving rod 201. The mounting block 205 is slidably sleeved on the connecting rod 202. The crash plate 206 is fixedly mounted on one outer wall of the mounting block 205. Both sealing rings 207 are sleeved on the mounting block 205. The dustproof plate 208 is disposed inside the outer casing assembly 1, and the retaining ring 209 is disposed inside the outer casing assembly 1. More specifically, when the mounting block 205 moves to perform piston movement, the mounting block 205... The moving sealing ring 207 is made of rubber and has good elasticity. It fills the gap between the mounting block 205 and the sleeve 102, preventing the injected gas from overflowing and causing insufficient thrust. When the mounting block 205 moves to fit against the front cover 101, it is blocked by the anti-collision plate 206. Because the anti-collision plate 206 is made of rubber, it prevents the mounting block 205 and the front cover 101 from colliding and deforming due to hard contact. The dustproof plate 208 seals the gap between the front cover 101 and the moving rod 201, preventing the moving rod 201 from rubbing against the front cover 101 during movement and preventing dust and impurities from entering the sleeve 102 through the gap. It has the advantages of protecting the inside of the mini cylinder, preventing damage caused by hard contact due to the short stroke of the mini cylinder, and sealing the mini cylinder to prevent air leakage and dust and impurities from entering.

[0024] In addition, two grooves are provided on the outer wall of the mounting block 205, and the two grooves are adapted to the two sealing rings 207.

[0025] In addition, the two sealing rings 207 are Y-shaped and arranged opposite each other.

[0026] In addition, the dustproof plate 208 is made of rubber and is ring-shaped.

[0027] like Figure 1As shown, the outer casing assembly 1 includes a front cover 101, a sleeve 102, a rear cover 103, a circular groove 104, an air outlet 105, and an air inlet 106. The sleeve 102 is fitted onto the front cover 101, and the rear cover 103 is inserted into the sleeve 102. The circular groove 104 is formed on one outer wall of the front cover 101, and the air outlet 105 is formed on the outer wall of the front cover 101, communicating with the circular groove 104. The air inlet 106 is formed on the rear cover 103. The moving rod 102 is slidably mounted on the front cover 101. The sleeve 102 is adapted to the mounting block 205. The dustproof plate 208 is fixedly mounted on the inner wall of the circular groove 104, and the retaining ring 208 is fixedly mounted on the circular groove. More specifically, on the inner wall of 104, take out the external air tube and align it with the air outlet 105 and air inlet 106 respectively. Push the external air tube into the air outlet 105 and air inlet 106. At this time, air is injected through the air tube in the external air source box. The gas enters the air inlet 106 through the air tube. The gas is introduced into the sleeve 102 through the air inlet 106 and pushes the mounting block 205 in the sleeve 102. The mounting block 205 drives the moving rod 201 to make piston movement. When the mounting block 205 moves, it pushes the original gas in the sleeve 102. The original gas is discharged through the air outlet 105. If the mini cylinder needs to retract, gas can be injected into the air outlet 105. It has the advantage of being easy to connect to the air source and inject gas for pushing.

[0028] In addition, a rubber ring is fitted on the front cover 101, a rubber ring is fitted on the rear cover 103, and the sleeve 102 is made of stainless steel.

[0029] Working principle:

[0030] Step 1: Connect the air supply. Take out the external air tube and align it with the air outlet 105 and air inlet 106 respectively. Push the external air tube into the air outlet 105 and air inlet 106. At this time, inject air through the air tube in the external air source box. The gas enters the air inlet 106 through the air tube. The gas is introduced into the sleeve 102 through the air inlet 106 and pushes the mounting block 205 in the sleeve 102. The mounting block 205 drives the moving rod 201 to make piston movement. When the mounting block 205 moves, it pushes the original gas in the sleeve 102. The original gas is discharged through the air outlet 105. If the mini cylinder needs to retract, simply inject gas into the air outlet 105.

[0031] Step Two: Work Protection. When the mounting block 205 moves to perform piston-like motion, the mounting block 205 drives the sealing ring 207 to move. The sealing ring 207 is made of rubber and has good elasticity. It fills the gap between the mounting block 205 and the sleeve 102 to prevent the injected gas from overflowing from the gap and causing insufficient thrust. When the mounting block 205 moves to fit against the front cover 101, it is blocked by the anti-collision plate 206. Because the anti-collision plate 206 is made of rubber, it prevents the mounting block 205 from colliding with the front cover 101 and causing hard contact that could deform and damage it. The dustproof plate 208 seals the gap between the front cover 101 and the moving rod 201, preventing the moving rod 201 from rubbing against the front cover 101 during movement and preventing dust and impurities from entering the sleeve 102 through the gap.
