Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinders, and in particular to a hydraulic cylinder with shock absorption and buffering. Background Technology

[0002] Hydraulic cylinders are common mechanical components that achieve linear motion through the pressure of hydraulic oil. They are widely used in various mechanical equipment, especially in situations where large forces are required to push or pull.

[0003] When using a hydraulic cylinder, hydraulic oil is delivered into the cylinder body through pipes, and then the piston rod moves and extends. A shock absorber is installed on one side of the cylinder body to reduce vibration and provide cushioning. During use, external debris and dust can easily be brought into the cylinder body, and if they accumulate, they can affect the performance of the hydraulic cylinder. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the piston rod of a hydraulic cylinder is in use, it is easy for external debris and dust to be brought into the cylinder body. After accumulating in large quantities, this can lead to problems that affect the performance of the hydraulic cylinder.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic cylinder with shock absorption and buffer, including a cylinder body, a piston rod provided on one side of the cylinder body, a pipe provided on one side of the cylinder body, a shock absorber provided on one side of the cylinder body, and a cleaning device provided on the side of the cylinder body near the piston rod. The cleaning device cleans the surface of the piston rod through a rubber ring and a scraper.

[0006] The effects achieved by the above components are as follows: when using the hydraulic cylinder, hydraulic oil is sent into the cylinder body through the pipeline, and then the piston rod moves and extends. A shock absorber is set on one side of the cylinder body to reduce vibration and buffer the impact. When the piston rod returns to its original position, the cleaning device cleans the surface of the piston rod of debris, dust and other impurities.

[0007] Preferably, the cleaning device includes a placement block, bolts, a connecting plate, a rubber ring, a fixing block, and a scraper. The placement block is located on the side of the cylinder body near the piston rod. The bolts fix the connecting plate inside the placement block. The rubber ring is located on the side of the connecting plate and fits against the placement block. The scraper is connected to the rubber ring through the fixing block, and the scraper is located on the side of the rubber ring away from the placement block. The dimensions of the rubber ring and the scraper are adapted to the dimensions of the piston rod.

[0008] The effects achieved by the above components are as follows: Before using the piston rod, move the rubber ring so that the connecting plates on both sides of the rubber ring are inserted into the placement block fixed to the cylinder body. At this time, the fixing block fixed to the rubber ring and scraper drives the scraper to approach the placement block, and both the rubber ring and the scraper are in contact with the outer surface of the piston rod. Then, rotate the bolt so that the bolt passes through the placement block and is threadedly fixed to the connecting plate to complete the fixing of the position of the rubber ring and the scraper. When the piston rod returns to the inside of the cylinder body, the scraper removes the adhering dust and debris, and the rubber ring is cleaned a second time to improve the cleaning and removal effect. By using the cleaning device, the debris and dust adhering to the surface of the piston rod can be cleaned and removed, preventing the debris and dust from being carried into the cylinder body by the piston rod and affecting the use of the hydraulic cylinder, thereby improving the use effect of the hydraulic cylinder.

[0009] Preferably, an operating block is provided on one side of the bolt, and the operating block increases the dimension of one side of the bolt.

[0010] The effect achieved by the above components is to increase the contact area between the bolt and the operator by using the operating block fixed on one side of the bolt, making the bolt easier to rotate.

[0011] Preferably, a trapezoidal block is provided on the side of the connecting plate away from the rubber ring, and the trapezoidal block reduces the size of one side of the connecting plate.

[0012] The effect achieved by the above components is to reduce the size of one side of the connecting plate by fixing the trapezoidal block on one side, making it easier for the connecting plate to be inserted into the block.

[0013] Preferably, a reinforcing plate is provided at the connection between the connecting plate and the rubber ring, and the reinforcing plate improves the connection strength between the connecting plate and the rubber ring.

[0014] The effect achieved by the above components is to increase the strength of the connection between the connecting plate and the rubber ring by fixing a reinforcing plate at the connection point, thereby preventing the connection point from separating under stress.

[0015] Preferably, the placement block is provided with a protective component on the side near the bolt. The protective component includes an extension plate and a protective plate. The extension plate is disposed on the side of the placement block near the bolt, and the protective plate slides inside the extension plate. The size of the protective plate is adapted to the size of the bolt.

[0016] The effect achieved by the above components is as follows: when using bolts, the protective plate can be moved so that it slides inside the extension plate fixed on one side of the placement block, and then the protective plate is brought close to the bolt to shield and protect the bolt. By using the protective components, the bolts can be shielded and protected to avoid collision damage, thereby improving the service life of the bolts.

[0017] Preferably, a magnet is provided on one side of the extension plate, and an iron sheet is provided on one side of the protective plate.

[0018] The effect achieved by the above components is as follows: by fixing magnets on the extension plate and iron sheets on the protective plate, the iron sheets on the protective plate are attracted by the magnets when the protective plate is in use, making the protective plate less prone to movement under force, thereby improving the effectiveness of the protective plate.

[0019] Preferably, the protective plate has several anti-slip blocks on the side near the iron sheet, and the several anti-slip blocks increase the friction on one side of the protective plate.

[0020] The effect achieved by the above components is to increase the friction between the operator and the protective plate by fixing several anti-slip blocks on one side of the protective plate, thereby making it easier for the operator to move the protective plate.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a cleaning device, debris and dust adhering to the surface of the piston rod can be removed, preventing them from being carried into the cylinder and affecting the performance of the hydraulic cylinder, thus improving its performance.

[0023] By using protective components, bolts can be shielded and protected from impact damage, thereby extending their service life. Attached Figure Description

[0032] Figures 1 to 4 The hydraulic cylinder shown includes a cylinder body 1, a piston rod 2 on one side of the cylinder body 1, a pipe 3 on one side of the cylinder body 1, a shock absorber 4 on one side of the cylinder body 1, and a cleaning device 5 on the side of the cylinder body 1 near the piston rod 2. The cleaning device 5 cleans the surface of the piston rod 2 using a rubber ring 54 and a scraper 56. When the hydraulic cylinder is in use, hydraulic oil is sent into the cylinder body 1 through the pipe 3, and then the piston rod 2 moves and extends. The shock absorber 4 on one side of the cylinder body 1 reduces vibration and provides cushioning. When the piston rod 2 returns to its original position, the cleaning device 5 cleans the surface of the piston rod 2 of debris, dust, and other impurities.

[0033] Figures 1 to 4The cleaning device 5 shown includes a placement block 51, bolts 52, connecting plate 53, rubber ring 54, fixing block 55, and scraper 56. The placement block 51 is located on the side of the cylinder 1 near the piston rod 2. The bolts 52 fix the connecting plate 53 to the inside of the placement block 51. The rubber ring 54 is located on the side of the connecting plate 53 and fits against the placement block 51. The scraper 56 is connected to the rubber ring 54 through the fixing block 55, and the scraper 56 is located on the side of the rubber ring 54 away from the placement block 51. The dimensions of the rubber ring 54 and the scraper 56 are adapted to the dimensions of the piston rod 2. Before using the piston rod 2, move the rubber ring 54 so that the connecting plates 53 on both sides of the rubber ring 54 are inserted into the placement block 51 fixed to the cylinder body 1. At this time, the fixing block 55, which is fixed to the rubber ring 54 and the scraper 56, drives the scraper 56 to approach the placement block 51, and both the rubber ring 54 and the scraper 56 are in contact with the outer surface of the piston rod 2. Then, rotate the bolt 52 so that the bolt 52 passes through the placement block 51 and is threadedly fixed to the connecting plate 53 to complete the fixing of the position of the rubber ring 54 and the scraper 56. When the piston rod 2 returns to the inside of the cylinder body 1, the scraper 56 removes the adhering dust and debris, and the rubber ring 54 performs a secondary cleaning to improve the cleaning and removal effect. By using the cleaning device 5, the debris and dust adhering to the surface of the piston rod 2 can be cleaned and removed, preventing the debris and dust from being carried into the inside of the cylinder body 1 by the piston rod 2 and affecting the use of the hydraulic cylinder, thereby improving the use effect of the hydraulic cylinder.

[0034] Figures 1 to 4 An operating block 57 is provided on one side of the bolt 52, which increases the size of one side of the bolt 52. By fixing the operating block 57 to one side of the bolt 52, the contact area between the bolt 52 and the operator is increased, making the bolt 52 easier to rotate. A trapezoidal block 58 is provided on the side of the connecting plate 53 away from the rubber ring 54, which decreases the size of one side of the connecting plate 53. By fixing the trapezoidal block 58 to one side of the connecting plate 53, the size of one side of the connecting plate 53 is decreased, making it easier for the connecting plate 53 to insert the placement block 51. A reinforcing plate 59 is provided at the connection between the connecting plate 53 and the rubber ring 54, which increases the connection strength between the connecting plate 53 and the rubber ring 54. By fixing the reinforcing plate 59 at the connection between the connecting plate 53 and the rubber ring 54, the strength of the connection between the connecting plate 53 and the rubber ring 54 is increased, preventing separation of the connection under stress.

[0035] Figures 1 to 4The placement block 51 shown is provided with a protective component 6 near the bolt 52. The protective component 6 includes an extension plate 61 and a protective plate 62. The extension plate 61 is disposed on the side of the placement block 51 near the bolt 52, and the protective plate 62 slides inside the extension plate 61. The size of the protective plate 62 is adapted to the size of the bolt 52. When using the bolt 52, the protective plate 62 can be moved so that it slides inside the extension plate 61 fixed on one side of the placement block 51, and then brought close to the bolt 52 to shield and protect the bolt 52. By using the protective component 6, the bolt 52 can be shielded and protected, avoiding impact damage and thus extending the service life of the bolt 52.

[0036] Figures 1 to 4 The extension plate 61 shown has a magnet 63 on one side, and the protective plate 62 has an iron sheet 64 on one side. By fixing the magnet 63 to the extension plate 61 and the iron sheet 64 to the protective plate 62, the magnet 63 attracts the iron sheet 64 to the protective plate 62 during use, making the protective plate 62 less prone to movement under force, thus improving its usability. Several anti-slip blocks 65 are provided on the side of the protective plate 62 near the iron sheet 64, increasing the friction on one side of the protective plate 62. By fixing several anti-slip blocks 65 to one side of the protective plate 62, the friction between the operator and the protective plate 62 is increased, making it easier for the operator to move the protective plate 62.

[0037] Working principle: When using the hydraulic cylinder, hydraulic oil is sent into the cylinder body 1 through the pipe 3, and then the piston rod 2 moves and extends. A shock absorber 4 is provided on one side of the cylinder body 1 to reduce vibration and buffer. When the piston rod 2 returns to its original position, the cleaning device 5 cleans the surface of the piston rod 2 of debris, dust and other impurities. Before using the piston rod 2, move the rubber ring 54 so that the connecting plates 53 on both sides of the rubber ring 54 are inserted into the placement block 51 fixed to the cylinder body 1. At this time, the fixing block 55, which is fixed to the rubber ring 54 and the scraper 56, drives the scraper 56 to approach the placement block 51, and both the rubber ring 54 and the scraper 56 are in contact with the outer surface of the piston rod 2. Then, rotate the bolt 52 so that the bolt 52 passes through the placement block 51 and is threadedly fixed to the connecting plate 53 to complete the fixing of the position of the rubber ring 54 and the scraper 56. When the piston rod 2 returns to the inside of the cylinder body 1, the scraper 56 removes the adhering dust and debris, and the rubber ring 54 performs a secondary cleaning to improve the cleaning and removal effect. By using the cleaning device 5, the debris and dust adhering to the surface of the piston rod 2 can be cleaned and removed, preventing the debris and dust from being carried into the inside of the cylinder body 1 by the piston rod 2 and affecting the use of the hydraulic cylinder, thereby improving the use effect of the hydraulic cylinder.

[0038] When using bolt 52, the protective plate 62 can be moved so that it slides inside the extension plate 61 fixed on one side of the placement block 51. Then, the protective plate 62 is brought close to bolt 52 to shield and protect bolt 52. By using the protective component 6, bolt 52 can be shielded and protected to prevent bolt 52 from being damaged by collision, thereby improving the service life of bolt 52.
