Description

Technical Field

[0001] This utility model relates to the field of mechanical connection accessories, and in particular to a steel pipe sleeve that facilitates adjustment of the piston rod angle. Background Technology

[0002] A piston rod steel tube sleeve is a mechanical component used to protect and reinforce the piston rod. It is usually made of high-strength steel and has the characteristics of wear resistance, corrosion resistance and high temperature resistance.

[0003] In various mechanical devices, piston rods often need to be connected to components in different directions to meet diverse operational requirements.

[0004] Traditional steel pipe sleeves are fixed at a fixed angle after being connected to piston rods, making it difficult to adjust them flexibly. Changing the angle of the piston rod often requires disassembling and reinstalling the entire connection structure, which is cumbersome and consumes a lot of time and manpower. It also affects the normal operating efficiency of the equipment. In addition, in some scenarios where high connection precision is required, traditional sleeves cannot precisely fine-tune the angle of the piston rod, making it difficult to guarantee the working performance of the equipment.

[0005] Therefore, developing a steel pipe sleeve that can conveniently and quickly adjust the piston rod angle is of great practical significance.

[0006] To address the above issues, we have developed a steel pipe sleeve that facilitates adjustment of the piston rod angle. Utility Model Content

[0007] This utility model discloses a steel pipe sleeve that facilitates adjustment of the piston rod angle, aiming to solve the technical problems in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A steel pipe sleeve for easy adjustment of piston rod angle includes a sleeve body and a piston rod body. The piston rod body is disposed inside the sleeve body. A threaded cap is threadedly connected to one side of the sleeve body. A sealing cap is connected to the end of the sleeve body away from the threaded cap via six internal hexagon screws. One end of the piston rod body passes through the sealing cap and is threadedly connected to a threaded rod. A fastening nut is threadedly connected to the external thread of the threaded rod. One side of the fastening nut contacts one end of the piston rod body. Both the threaded cap away from the sleeve body and the threaded rod away from the piston rod body are fixedly connected to an annular connector. A connecting ball is provided inside each annular connector. An installation rod is fixedly connected to one side of each connecting ball. A split nut is threadedly connected to the end of the installation rod away from the connecting ball.

[0010] The workers first install the sleeve body on the fixed part of the equipment, and then connect the threaded cover with the threaded connection. Next, the piston rod body is passed through the sealing cover, and the sealing cover is fixed to the sleeve body with an internal hex screw. The threaded rod is screwed to one end of the piston rod body, and the fastening nut is tightened to ensure a stable connection. After that, the angle of the installation rod can be flexibly adjusted through the connecting ball head in the annular connector to adapt to different installation requirements of the equipment.

[0011] In a preferred embodiment, a piston body is slidably connected inside the sleeve body, and a connecting rod is fixedly connected to the end of the piston rod body away from the threaded rod. The end of the connecting rod away from the piston rod body passes through the piston body and is threadedly connected to a connecting nut. One side of the connecting nut contacts one side of the piston body.

[0012] During the commissioning process of the aforementioned automated equipment, when hydraulic oil is injected into the sleeve body, the hydraulic oil pushes the piston body to slide inside the sleeve body. Since the piston rod body is connected to the piston body through the connecting rod and connecting nut, the sliding of the piston body will cause the piston rod body to move in a straight line.

[0013] In a preferred embodiment, two sealing rings are embedded in the outside of the piston body, and both sealing rings are in contact with the inner wall of the sleeve body.

[0014] By being installed during long-term operation of the equipment, the sealing ring plays a crucial sealing role. When hydraulic oil pushes the piston body to move inside the sleeve body, the sealing ring prevents hydraulic oil from leaking from the gap between the piston body and the sleeve body.

[0015] In a preferred embodiment, a sealing oil seal is embedded inside the sealing cap, and the sealing oil seal is in contact with the outer side of the piston rod body.

[0016] By setting the sealing oil seal during equipment operation, the sealing performance of the steel pipe sleeve is further enhanced, preventing hydraulic oil inside the sleeve body from leaking into the external environment through the gap between the piston rod body and the sealing cover.

[0017] In a preferred embodiment, two hydraulic oil connectors are fixedly connected to the outer side of the sleeve body. The bottom of each hydraulic oil connector extends into the interior of the sleeve body, and the top of each hydraulic oil connector is connected to the input and output ends of an external hydraulic station, respectively.

[0018] During the equipment assembly process, workers connect two hydraulic oil connectors to the input and output ends of an external hydraulic station, respectively. When the hydraulic station is working, hydraulic oil enters the sleeve body through one hydraulic oil connector, pushing the piston body to move and complete the corresponding action. Then, the hydraulic oil flows back to the hydraulic station through the other hydraulic oil connector.

[0019] In a preferred embodiment, the annular connector is connected to a back cover on the side away from the mounting rod by six external hexagonal screws.

[0020] After the equipment is installed, in order to protect the connecting ball head inside the annular connector, the worker uses external hexagonal screws to install the back cover on the annular connector. The back cover can prevent dust, debris and other objects from entering the interior of the annular connector and affecting the rotation flexibility of the connecting ball head.

[0021] In a preferred embodiment, each of the mounting rods has a through groove inside, and each through groove has a limiting pin inserted inside, which is used in conjunction with a corresponding perforated nut.

[0022] To prevent the mounting rod from loosening after connecting it to other components using a perforated nut, a limit pin is inserted into the through groove of the mounting rod. The limit pin engages with the perforated nut, restricting its rotation and ensuring the stability of the connection.

[0023] The steel pipe sleeve provided by this utility model, which facilitates the adjustment of the piston rod angle, has the following advantages:

[0024] In this invention, the piston rod body passes through the sealing cover, and the sealing cover is fixed to the sleeve body with an internal hex screw. The threaded rod is screwed to one end of the piston rod body, and the fastening nut is tightened to ensure a stable connection. Then, the angle of the mounting rod can be flexibly adjusted through the connecting ball head in the annular connector. By using the cooperation of the fastening nut and the threaded rod, the angle of the piston rod body can be adjusted conveniently and quickly without disassembling and reinstalling the entire connection structure, greatly saving time and labor costs. It can reliably lock the angle of the piston rod, ensuring the stability of the connection during equipment operation, improving equipment safety, and greatly improving the quality of operation and efficiency compared to traditional devices.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] The steel pipe sleeve disclosed in this utility model, which facilitates the adjustment of the piston rod angle, is mainly used in mechanical connection parts.

[0033] Reference Figures 1-5 A steel pipe sleeve for easy adjustment of piston rod angle includes a sleeve body 1 and a piston rod body 2. The piston rod body 2 is disposed inside the sleeve body 1. A threaded cap 21 is threadedly connected to one side of the sleeve body 1. A sealing cap 3 is connected to the end of the sleeve body 1 away from the threaded cap 21 by six internal hexagon screws 4. One end of the piston rod body 2 passes through the sealing cap 3 and is threadedly connected to a threaded rod 9. A fastening nut 10 is threadedly connected to the outside of the threaded rod 9. One side of the fastening nut 10 contacts one end of the piston rod body 2. Both the side of the threaded cap 21 away from the sleeve body 1 and the end of the threaded rod 9 away from the piston rod body 2 are fixedly connected to an annular connector 5. A connecting ball head 6 is provided inside the annular connector 5. An installation rod 7 is fixedly connected to one side of the connecting ball head 6. A flower nut 8 is threadedly connected to the end of the installation rod 7 away from the connecting ball head 6.

[0034] In this embodiment: the worker first installs the sleeve body 1 on the fixed part of the equipment, and then connects the threaded cover 21 by thread. Next, the piston rod body 2 passes through the sealing cover 3, and the sealing cover 3 is fixed to the sleeve body 1 with the hexagon socket screw 4. The threaded rod 9 is screwed to one end of the piston rod body 2, and the fastening nut 10 is tightened to ensure a stable connection. After that, the angle of the mounting rod 7 can be flexibly adjusted by the connecting ball head 6 in the annular connector 5 to adapt to different installation requirements of the equipment.

[0035] In a preferred embodiment, a piston body 11 is slidably connected inside the sleeve body 1, and a connecting rod 12 is fixedly connected to the end of the piston rod body 2 away from the threaded rod 9. The end of the connecting rod 12 away from the piston rod body 2 passes through the piston body 11 and is threadedly connected to a connecting nut 13. One side of the connecting nut 13 is in contact with one side of the piston body 11.

[0036] In this embodiment: During the commissioning of the above-mentioned automated equipment, when hydraulic oil is injected into the sleeve body 1, the hydraulic oil pushes the piston body 11 to slide inside the sleeve body 1. Since the piston rod body 2 is connected to the piston body 11 through the connecting rod 12 and the connecting nut 13, the sliding of the piston body 11 will drive the piston rod body 2 to make linear motion.

[0037] In a preferred embodiment, two sealing rings 14 are embedded on the outside of the piston body 11, and both sealing rings 14 are in contact with the inner wall of the sleeve body 1.

[0038] In this embodiment, during the long-term operation of the equipment, the sealing ring 14 plays a crucial sealing role. When the hydraulic oil pushes the piston body 11 to move inside the sleeve body 1, the sealing ring 14 prevents the hydraulic oil from leaking from the gap between the piston body 11 and the sleeve body 1.

[0039] In a preferred embodiment, a sealing oil seal 15 is embedded inside the sealing cap 3, and the sealing oil seal 15 is in contact with the outer side of the piston rod body 2.

[0040] In this embodiment, during equipment operation, the sealing oil seal 15 further enhances the sealing performance of the steel pipe sleeve, preventing the hydraulic oil inside the sleeve body 1 from leaking into the external environment through the gap between the piston rod body 2 and the sealing cover 3.

[0041] In a preferred embodiment, two hydraulic oil connectors 16 are fixedly connected to the outside of the sleeve body 1. The bottom of each hydraulic oil connector 16 extends into the inside of the sleeve body 1, and the top of each hydraulic oil connector 16 is connected to the input and output ends of an external hydraulic station, respectively.

[0042] In this embodiment: During the assembly process of the equipment, the worker connects the two hydraulic oil connectors 16 to the input and output ends of the external hydraulic station respectively. When the hydraulic station is working, the hydraulic oil enters the sleeve body 1 through one hydraulic oil connector 16, pushes the piston body 11 to move, and completes the corresponding action. Then, the hydraulic oil flows back to the hydraulic station through the other hydraulic oil connector 16.

[0043] In a preferred embodiment, the annular connector 5 is connected to a rear cover 17 on the side away from the mounting rod 7 by six external hexagonal screws 18.

[0044] In this embodiment: After the equipment is installed, in order to protect the connecting ball head 6 inside the annular connector 5, the worker uses an external hexagonal screw 18 to install the back cover 17 on the annular connector 5. The back cover 17 can prevent dust, debris and other objects from entering the interior of the annular connector 5 and affecting the rotation flexibility of the connecting ball head 6.

[0045] In a preferred embodiment, each of the mounting rods 7 has a through groove 19 inside, and each through groove 19 has a limiting pin 20 inserted inside, which is used in conjunction with the corresponding flower nut 8.

[0046] In this embodiment: after the mounting rod 7 is connected to other components using the flower nut 8, in order to prevent the flower nut 8 from loosening, the worker inserts the limiting pin 20 into the through groove 19 of the mounting rod 7. The limiting pin 20 cooperates with the flower nut 8 to restrict the rotation of the flower nut 8 and ensure the stability of the connection.

[0047] Working principle: In use, firstly, the sleeve body 1 is connected to the external hydraulic station through the hydraulic oil connector 16. The hydraulic oil enters the sleeve body 1 through the hydraulic oil connector 16, pushing the piston body 11 to slide inside the sleeve body 1.

[0048] The piston body 11 is connected to the piston rod body 2 via the connecting rod 12. The connecting nut 13 ensures a stable connection between the piston body 11 and the connecting rod 12. One end of the piston rod body 2 is connected to the fastening nut 10 via the threaded rod 9. Adjusting the screw depth of the threaded rod 9 can adjust the angle of the piston rod body 2.

[0049] The sealing ring 14 and the sealing oil seal 15 ensure the sealing of the inside of the sleeve body 1 and prevent hydraulic oil leakage;

[0050] The annular connector 5 is connected to the mounting rod 7 via the connecting ball head 6. The mounting rod 7 is fixed to the external equipment via the flower nut 8. The connecting ball head 6 allows the mounting rod 7 to rotate freely within a certain angle range, thereby enabling flexible adjustment of the angle of the piston rod body 2.

[0051] The limit pin 20 is inserted into the through groove 19 to prevent the flower nut 8 from loosening and to ensure a stable connection between the mounting rod 7 and the external equipment;

[0052] The entire device uses hydraulic oil to drive the piston body 11 and piston rod body 2. The angle of the piston rod body 2 can be flexibly adjusted by connecting ball head 6 and mounting rod 7. The sealing ring 14 and sealing oil seal 15 ensure sealing performance. The limit pin 20 and flower nut 8 ensure a stable connection of mounting rod 7. It is suitable for hydraulic equipment that requires flexible adjustment of piston rod angle, improving the applicability and ease of operation of the equipment.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
