AI Technical Summary
When the cylinder is intaked, especially in cylinders with long strokes and high speeds, the piston's impact on the end cap can cause excessive kinetic energy, which can easily damage parts and shorten the cylinder's lifespan.
A cylinder intake buffer structure was designed, including a cylinder body, a cylinder seat, a cylinder end cover, and a piston rod. A No. 1 washer made of soft rubber and a No. 2 washer made of aluminum alloy are used to achieve buffering through the compression of a spring. The main chamber is divided into No. 1 and No. 2 chambers. The intake port is located above the No. 1 washer. When the piston moves, the compression spring and the gas at the bottom of the No. 2 washer are used for buffering.
It effectively reduces airflow pulses, protects cylinder parts, and extends cylinder life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer structures, and more particularly to a cylinder intake buffer structure. Background Technology
[0002] The function of a cylinder is to convert the pressure energy of compressed air into mechanical energy through the reciprocating motion of a piston, thereby driving the machine body to perform linear reciprocating motion, oscillation, or rotation. As a key component in power equipment, the cylinder achieves the effective output of mechanical energy or power through its compression or expansion action, and is widely used in various equipment such as internal combustion engines, compressors, and hydraulic presses.
[0003] When a cylinder is in use, it needs to continuously take in air. When the piston moves to the end of the cylinder, especially in cylinders with long strokes and high speeds, the kinetic energy of the piston hitting the end cap will be very large, which can easily damage parts and shorten the life of the cylinder. Therefore, a cylinder intake buffer structure is provided. Utility Model Content
[0004] The main purpose of this utility model is to provide a cylinder intake buffer structure to solve the problem mentioned in related technologies that when the piston moves to the end of the cylinder during intake, especially in cylinders with long strokes and high speeds, the kinetic energy of the piston hitting the end cover is very large, which can easily damage parts and shorten the life of the cylinder.
[0005] To achieve the above objectives, according to one aspect of the present invention, a cylinder intake buffer structure is provided, comprising a cylinder body, a cylinder seat fixedly installed on one side of the cylinder body, a main chamber opened in the cylinder body, a second washer slidably disposed in the main chamber, the second washer dividing the main chamber into a first chamber and a second chamber, a piston slidably installed in the first chamber, and a first washer fixedly installed on one side of the cylinder seat located in the main chamber, and further comprising: a cylinder end cap, the cylinder end cap fixedly installed on the other side of the cylinder body, an air outlet opened on one side of the cylinder end cap, a through hole through the center of the cylinder end cap, a piston rod slidably installed in the through hole, and one side of the piston rod fixedly installed on the piston.
[0006] Furthermore, the first washer is made of soft rubber, and the side of the first washer near the second washer is convex.
[0007] Furthermore, a spring is fixedly installed on the raised surface of the first washer, and the other end of the spring is fixedly installed on one side of the second washer.
[0008] Furthermore, the second washer is made of aluminum alloy.
[0009] Furthermore, the sidewall of the second washer is in close contact with the inner wall of the cylinder.
[0010] Furthermore, an air inlet is provided through the side wall of the cylinder block, and the air inlet is always located above the No. 1 gasket.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The cylinder intake buffer structure is equipped with a No. 2 washer, which divides the main chamber into a No. 1 chamber and a No. 2 chamber. The piston is slidably installed in the No. 2 chamber. One side of the No. 1 washer is fixedly installed on the cylinder seat, and the other side of the No. 1 washer is convex. When the cylinder intakes, the piston compresses the spring, and the spring compression plays a buffering role. The addition of the No. 2 washer and the spring in the airflow direction makes the airflow pulse smaller.
[0013] 2. The cylinder intake buffer structure is equipped with an intake port located above the No. 2 washer. The No. 2 washer is in close contact with the side wall of the cylinder. When the piston moves downward, it compresses the gas at the bottom of the No. 2 washer, and the air pressure plays a buffering role. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0022] Please see Figures 1-2As shown, the purpose of this embodiment is to provide a cylinder intake buffer structure, including a cylinder body 1, a cylinder seat 4 fixedly installed on one side of the cylinder body 1, a main chamber 13 opened inside the cylinder body 1, a second washer 121 slidably disposed in the main chamber 13, the second washer 121 dividing the main chamber 13 into a first chamber 11 and a second chamber 12, a piston 31 slidably installed in the second chamber 12, a first washer 111 fixedly installed on one side of the cylinder seat 4 located inside the main chamber 13, and also including: a cylinder end cap 2, the cylinder end cap 2 fixedly installed on the other side of the cylinder body 1, an outlet 21 opened on one side of the cylinder end cap 2, one end of the outlet 21 communicating with the second chamber 12, a through hole 22 penetrating through the center of the cylinder end cap 2, a piston rod 3 slidably installed in the through hole 22, one side of the piston rod 3 fixedly installed on the piston 31. An intake port 14 opened on the side wall of the cylinder body 1, the intake port 14 communicating with the first chamber 11.
[0023] Washer 111 is made of soft rubber. The side of Washer 111 that is close to Washer 2121 is raised, which increases the cushioning capacity of Washer 111.
[0024] A spring 112 is fixedly installed on the raised surface of the first washer 111. The other end of the spring 112 is fixedly installed on one side of the second washer 121. When air is intake, the spring 112 is compressed as a buffer. The second washer 121 and the spring 112 are located in the airflow direction, making the airflow pulse smaller.
[0025] Washer No. 2, 121, is made of aluminum alloy. The aluminum alloy material of Washer No. 2, 121 increases the strength of Washer No. 2, 121 during cushioning.
[0026] The side wall of the No. 2 washer 121 is in close contact with the inner wall of the cylinder 1. During buffering, the gas compression at the bottom of the No. 2 washer 121 provides buffering.
[0027] An air inlet 14 is provided through the side wall of the cylinder block 1, and the air inlet 14 is always located above the No. 1 gasket 111.
[0028] In practical use, when the cylinder is intake, the piston 31 moves along the first cavity 11 towards the cylinder seat 4. When the piston 31 contacts the second washer 121, it compresses the spring 112 downwards. The compression spring 112 acts as a buffer. The second washer 121 and the spring 112 are located in the airflow direction, making the airflow pulse smaller. The second washer 121 is in close contact with the inner wall of the cylinder 1. When it moves downwards, it compresses the air at the bottom of the second washer 121, which acts as a buffer. When the second washer 121 contacts the first washer 111, it also acts as a buffer.
