Description

Technical Field

[0001] The utility model belongs to the technical field of cylinders, and specifically refers to a cylinder based on magnetic buffering. Background Art

[0002] A cylinder is a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder, and is composed of a cylinder barrel, a cylinder head, a piston, a piston rod, seals, etc.

[0003] During the use of the cylinder, when the piston slides towards the cylinder head, since the piston will impact the cylinder head, it is easy to cause serious wear of the cylinder head and greatly reduce the service life. Therefore, it is common to install rubber buffer pads on both sides of the piston to absorb the impact by the elasticity of the buffer pads. However, there are still some deficiencies: the buffer pads are prone to deformation under impact, affecting the service life of the buffer pads. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the existing cylinder with buffer pads, after long-term use, the buffer pads are prone to be squeezed and deformed, affecting the service life.

[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a cylinder based on magnetic buffering, including a cylinder barrel, a guide sleeve is arranged in the cylinder barrel, an air inlet valve and an air outlet valve are arranged on the side wall of the cylinder barrel, a guide sleeve is arranged at one end in the cylinder barrel, a telescopic rod passes through the guide sleeve, a piston plate is arranged at the end of the telescopic rod and is located in the cylinder barrel, and a plugging buffer assembly is arranged at the other end of the cylinder barrel; the plugging buffer assembly includes a plugging plate, a threaded plug is arranged on the plugging plate and is in internal thread connection with the inner wall of the cylinder barrel, a sealing ring is arranged on the plugging plate, a proximity switch is embedded in the threaded plug, an electromagnetic device is arranged at the end of the threaded plug, a magnet is arranged in the piston plate, and a connecting wire is arranged in the plugging plate and is electrically connected to the electromagnetic device and the proximity switch. By screwing the threaded plug into the cylinder barrel, the cylinder barrel can be plugged. When the piston plate approaches the proximity switch, the electromagnetic device will be powered on, generating an electromagnetic force on the magnet, which can buffer the piston plate and avoid direct collision.

[0006] Further, a first buffer pad is arranged on the piston plate, a second buffer pad is arranged at the end of the threaded plug, and the first buffer pad and the second buffer pad are of equal size.

[0007] Preferably, a limiting strip is arranged in the guide sleeve, a limiting groove is arranged in the telescopic rod, the limiting strip is located in the limiting groove, and the telescopic rod can avoid rotation when sliding into the guide sleeve.

[0008] Preferably, both the first buffer pad and the second buffer pad have a thickness.

[0009] Preferably, when the electromagnetic device is powered on, it can generate a counter magnetic force on the magnet.

[0010] Preferably, the magnet is embedded in the piston plate, and the electromagnetic device is embedded in the threaded plug.

[0011] The beneficial effects of the present utility model adopting the above structure are as follows:

[0012] By setting the plugging and buffering assembly, the present utility model can realize the plugging and installation of the cylinder barrel. When the piston plate slides in the cylinder barrel and reaches the proximity distance of the proximity switch, the electromagnetic device will be automatically powered on and generate a reverse magnetic force on the magnet, which can achieve the buffering protection of the piston plate and extend the service life of the buffer pad.

Detailed Embodiment

[0018] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0020] As Figures 1-4 , a cylinder based on magnetic buffering of the present utility model includes a cylinder barrel 1. A guide sleeve 4 is provided inside the cylinder barrel 1. An air inlet valve 2 and an air outlet valve 3 are provided on the side wall of the cylinder barrel 1. A guide sleeve 4 is provided at one end inside the cylinder barrel 1. A telescopic rod 5 is inserted through the guide sleeve 4. A limiting strip 17 is provided in the guide sleeve 4, and a limiting groove 18 is provided in the telescopic rod 5. The limiting strip 17 is located in the limiting groove 18. When the telescopic rod 5 slides in the guide sleeve 4, it can avoid rotation. The end of the telescopic rod 5 is provided with a piston plate 6 and is located in the cylinder barrel 1. A plugging and buffering assembly 7 is provided at the other end of the cylinder barrel 1.

[0021] As Figures 1-4 , the plugging and buffering assembly 7 includes a plugging plate 8. A threaded plug 10 is provided on the plugging plate 8 and is in threaded connection with the inner wall of the cylinder barrel 1. A first buffer pad 15 is provided on the piston plate 6. A second buffer pad 16 is provided at the end of the threaded plug 10. The first buffer pad 15 and the second buffer pad 16 are of equal size, and both the first buffer pad 15 and the second buffer pad 16 have a thickness. A sealing ring 11 is provided on the plugging plate 8. A proximity switch 14 is embedded in the threaded plug 10. An electromagnetic device 12 is provided at the end of the threaded plug 10. A magnet 13 is provided inside the piston plate 6. A connecting wire 9 is provided in the plugging plate 8 and is electrically connected to the electromagnetic device 12 and the proximity switch 14. When the electromagnetic device 12 is powered on, it can generate a reverse magnetic force on the magnet 13. By screwing the threaded plug 10 into the cylinder barrel 1, the cylinder barrel 1 can be plugged. When the piston plate 6 approaches the proximity switch 14, the electromagnetic device 12 will be powered on, generating an electromagnetic force on the magnet 13, which can buffer the piston plate 6 and avoid direct collision.

[0022] As Figures 1-2 , the magnet 13 is embedded in the piston plate 6, and the electromagnetic device 12 is embedded in the threaded plug 10.

[0023] During specific use, the piston plate 6 in the cylinder barrel 1 is pushed by the intake valve 2. The telescopic rod 5 will slide and extend in the guide sleeve 4. When the telescopic rod 5 slides in the guide sleeve 4, the limiting strip 17 will limit the rotation of the telescopic rod 5. When the telescopic rod 5 needs to retract, air is introduced through the outlet valve 3 and exhausted through the intake valve 2, then the reverse movement of the piston plate 6 can be achieved. When the piston plate 6 moves to a distance close to the proximity switch 14, the electromagnetic device 12 will be automatically activated, generating a reverse thrust on the magnet 13, which can prevent the piston plate 6 from directly hitting the threaded plug 10, achieving a buffering effect. At the same time, the first buffer pad 15 and the second buffer pad 16 can also buffer the piston plate 6.

[0024] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
