Rotary piston rod

Abstract

This utility model relates to the field of piston rod technology and discloses a rotating piston rod, including a piston rod with a mounting component threaded to its surface and an extension block fixedly connected to its surface. This utility model uses a lever to drive a pressing rod, which in turn stretches a telescopic spring and rotates a shaped locking block at a suitable position, causing it to sequentially engage with a through groove and a non-through groove. Finally, under the reset action of the telescopic spring, the shaped locking block is tightly engaged inside the non-through groove. This not only achieves a firm connection between the piston rod and the mounting component but also significantly enhances the connection stability through a dual connection method, combining threaded connection and locking block engagement. This effectively avoids the loosening problem caused by vibration and wear in traditional single threaded connections during long-term operation, greatly improving the reliability of the device under complex working conditions and ensuring the stable operation of the piston rod in subsequent work.

Description

Technical Field

[0001] This utility model relates to the field of piston rod technology, and in particular to a rotating piston rod. Background Technology

[0002] A rotating piston rod is a special mechanical component widely used in hydraulic and pneumatic systems to transmit power and achieve reciprocating motion. Unlike traditional linear piston rods, rotating piston rods can not only achieve linear reciprocating motion, but also achieve rotational motion under specific structural designs, thereby meeting more complex mechanical requirements.

[0003] Traditional piston rod connections to mounting components primarily rely on threaded connections. While simple and easy to operate, this method is prone to loosening during prolonged operation, especially under complex conditions such as vibration and impact. This leads to a decrease in the fit accuracy between the piston rod and the mounting component, affecting the normal operation of the equipment, and even causing malfunctions, increasing maintenance costs and downtime. Furthermore, traditional threaded connections often fail to meet the high stability requirements of equipment in high-intensity, high-frequency working environments. For example, in some high-precision hydraulic or pneumatic systems, the stability and accuracy of the piston rod are crucial to the equipment's performance. Once the connection loosens, it not only affects the equipment's accuracy but may also cause the equipment to malfunction or even damage other components. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rotating piston rod.

[0005] This utility model is achieved using the following technical solution: a rotating piston rod, comprising a piston rod, a mounting component threadedly connected to the surface of the piston rod, an extension block fixedly connected to the surface of the piston rod, a through groove formed on the surface of the extension block, a non-through groove formed on the surface of the mounting component, a paddle slidably connected to the surface of the mounting component, a support rod fixedly connected to the surface of the paddle, a shaped locking block rotatably connected to the surface of the support rod, a pressing rod fixedly connected to the surface of the paddle, and a telescopic spring fixedly connected to the surface of the pressing rod.

[0006] The above technical solution employs a dual connection method combining threaded connection and irregularly shaped locking block, effectively avoiding the instability that traditional single threaded connection is prone to during long-term operation. This significantly enhances the connection stability between the piston rod and the mounting parts, thereby ensuring the stability of the piston rod in subsequent operations and improving the reliability and service life of the entire device.

[0007] As a further improvement to the above solution, two extension blocks are provided, and the two extension blocks are respectively fixedly connected to both sides of the outer surface of the piston rod.

[0008] As a further improvement to the above solution, the irregularly shaped card block is engaged inside the non-penetrating slot, and the irregularly shaped card block is adapted to the penetrating slot.

[0009] As a further improvement to the above solution, guide grooves are provided on both sides of the outer surface of the mounting component, and the paddle is slidably connected to the inside of the guide groove.

[0010] Through the above technical solution, the guide groove provides a stable guiding effect for the movement of the paddle, avoiding the paddle from deviating or jamming during movement, and improving the operational stability and ease of operation of the device.

[0011] As a further improvement to the above solution, a sleeve is fixedly connected to the inner wall of the guide groove, and the telescopic spring is fixedly connected to the inner wall of the sleeve.

[0012] Through the above technical solution, the sleeve effectively protects the telescopic spring, preventing it from being interfered with or damaged by external factors during operation. At the same time, it provides stable support for the telescopic spring, ensuring the stability and reliability of its working performance.

[0013] As a further improvement to the above solution, the mounting component has an embedded cavity inside, and the piston rod has an external thread on its surface.

[0014] As a further improvement to the above solution, the embedded cavity is adapted to the piston rod, and one end of the piston rod is threaded into the interior of the embedded cavity via an external thread.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a lever to drive the compression rod, which in turn stretches the telescopic spring and rotates the irregularly shaped locking block at a suitable position. This allows the block to engage sequentially with the through slot and the non-through slot. Finally, under the reset action of the telescopic spring, the irregularly shaped locking block is tightly locked into the non-through slot. This not only achieves a firm connection between the piston rod and the mounting component, but also significantly enhances the connection stability through a dual connection method, combining threaded connection and locking block engagement. This effectively avoids the loosening problem caused by vibration and wear in traditional single threaded connections during long-term operation, greatly improving the reliability of the device under complex working conditions and ensuring the stable operation of the piston rod in subsequent work.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example: Please combine Figure 1-5 This embodiment of a rotating piston rod includes a piston rod 1, a mounting component 2 threadedly connected to the surface of the piston rod 1, an extension block 3 fixedly connected to the surface of the piston rod 1, a through groove 4 formed on the surface of the extension block 3, a non-through groove 5 formed on the surface of the mounting component 2, a lever 6 slidably connected to the surface of the mounting component 2, a support rod 7 fixedly connected to the surface of the lever 6, a shaped locking block 8 rotatably connected to the surface of the support rod 7, a pressing rod 9 fixedly connected to the surface of the lever 6, and a telescopic spring 10 fixedly connected to the surface of the pressing rod 9. The operator first threads the piston rod 1 and the mounting component 2 to achieve initial installation. After installation, the lever 6 is pulled to move the piston rod 1 towards the mounting component 2. As the extension block 3 moves in the direction of the extension block 3, the lever 6 drives the compression rod 9 to move, which in turn stretches the telescopic spring 10. When the lever 6 moves to the appropriate position, the irregularly shaped locking block 8 on the support rod 7 is rotated so that it coincides with the through groove 4 on the surface of the extension block 3. Then, the lever 6 is pulled to make the irregularly shaped locking block 8 completely pass through the through groove 4. After that, the irregularly shaped locking block 8 is rotated again so that it coincides with the non-through groove 5 on the surface of the mounting part 2. The lever 6 is released, and under the reset action of the telescopic spring 10, the compression rod 9 is retracted, which drives the lever 6 to retract. Finally, the irregularly shaped locking block 8 is tightly locked into the non-through groove 5, thereby further strengthening the connection stability between the piston rod 1 and the mounting part 2.

[0020] There are two extension blocks 3, which are fixedly connected to both sides of the outer surface of the piston rod 1.

[0021] The irregularly shaped locking block 8 is engaged inside the non-penetrating slot 5. The irregularly shaped locking block 8 is compatible with the through slot 4. In actual operation, when the irregularly shaped locking block 8 coincides with the through slot 4, it can pass through the through slot 4 smoothly; while when it coincides with the non-penetrating slot 5, it can be tightly locked into the non-penetrating slot 5, so as to achieve a firm connection between the piston rod 1 and the mounting part 2.

[0022] Guide grooves 12 are provided on both sides of the outer surface of the mounting part 2. The paddle 6 is slidably connected to the inside of the guide groove 12. The guide groove 12 provides a clear path and direction for the movement of the paddle 6, so that the paddle 6 can slide smoothly and accurately along the predetermined trajectory during the pulling and retraction process.

[0023] A sleeve 11 is fixedly connected to the inner wall of the guide groove 12, and a telescopic spring 10 is fixedly connected to the inner wall of the sleeve 11. The sleeve 11 provides a stable installation position and support structure for the telescopic spring 10, so that the telescopic spring 10 can maintain a good working state during the stretching and resetting process, ensuring that it can accurately and reliably provide a resetting force for the pressing rod 9, thereby driving the paddle 6 to retract smoothly and realizing the tight engagement between the irregularly shaped card block 8 and the non-penetrating card groove 5.

[0024] The mounting component 2 has an embedded cavity 13 inside, and the piston rod 1 has an external thread 14 on its surface.

[0025] The embedded cavity 13 is adapted to the piston rod 1, and one end of the piston rod 1 is threaded into the interior of the embedded cavity 13 through the external thread 14.

[0026] The implementation principle of a rotating piston rod in this embodiment is as follows: First, the personnel connect the piston rod 1 and the mounting part 2 with threads to complete the initial installation. After the installation is completed, the personnel pull the lever 6 and pull the lever 6 along the guide grooves 12 on both sides of the outer surface of the mounting part 2 to make it move towards the extension block 3. During this process, the lever 6 drives the extrusion rod 9 fixedly connected to its surface to move, thereby stretching the telescopic spring 10 fixedly connected to the surface of the extrusion rod 9.

[0027] When the lever 6 moves to the appropriate position, rotate the irregularly shaped locking block 8, which is rotatably connected to the surface of the lever 6 via the support rod 7, so that it coincides with the through groove 4 on the surface of the extension block 3. There are two extension blocks 3, which are fixedly connected to both sides of the outer surface of the piston rod 1. This structure provides stable support for the cooperation between the irregularly shaped locking block 8 and the through groove 4. Then, continue to pull the lever 6 so that the irregularly shaped locking block 8 passes completely through the through groove 4. Then, rotate the irregularly shaped locking block 8 again so that it coincides with the non-through groove 5 on the surface of the mounting part 2. At this time, the irregularly shaped locking block 8 and the non-through groove 5 are tightly engaged, so as to achieve a firm connection between the piston rod 1 and the mounting part 2.

[0028] Finally, the operator releases the tension on the lever 6. Under the reset action of the telescopic spring 10, the squeezing rod 9 retracts, causing the lever 6 to smoothly retract along the guide groove 12. This ultimately allows the irregularly shaped locking block 8 to be tightly locked into the non-penetrating groove 5, thereby further enhancing the connection stability between the piston rod 1 and the mounting part 2. This avoids the instability that can easily occur in traditional single threaded connections during long-term operation. This dual connection method ensures the stability of the piston rod 1 in subsequent operations.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
