Description

Technical Field

[0001] This invention relates to the field of hydraulic wrench technology, and in particular to rotatable hose fittings and multi-angle adaptive hydraulic wrenches. Background Technology

[0002] In the field of hydraulic wrench operation, although some hydraulic wrenches are equipped with unidirectional rotary joints, their adjustment functions are significantly limited. During operation, the angle needs to be adjusted by dragging the oil pipe or rotating the oil pipe as a whole. The operator needs to continuously apply external force to maintain the position of the oil pipe. Prolonged operation can easily cause hand muscle fatigue and increase the risk of operational errors. At the same time, repeated dragging and rotation will aggravate the friction wear between the oil pipe and the joint, especially causing continuous damage to the seals at the interface, leading to premature aging and failure of the seals. This not only increases the equipment maintenance cost, but may also cause hydraulic oil leakage due to poor sealing, resulting in system pressure loss.

[0003] Furthermore, the limitations of traditional hydraulic wrenches in adaptability to complex working conditions are particularly pronounced. When faced with scenarios where bolts are scattered, working spaces are narrow, or bolts are arranged at an angle, the fixed-angle hydraulic hose connector is difficult to adjust flexibly, and the hydraulic hose is prone to rigid interference with surrounding equipment components. This results in the wrench not being able to accurately align with the bolt center, requiring operators to repeatedly disassemble and reposition the wrench, and even need to use auxiliary tools to adjust the working position, which not only significantly extends the working time but also reduces construction efficiency. Therefore, those skilled in the art have provided rotatable hydraulic hose connectors and multi-angle adaptive hydraulic wrenches to solve the problems mentioned in the background art. Summary of the Invention

[0004] (I) Technical Solution

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a rotatable oil pipe joint and a multi-angle adaptive hydraulic wrench, including a wrench body and an oil pipe port at one end of the wrench body. Rotating structure two includes an adapter two located outside the oil pipe port, a connecting pipe three located at one end of the adapter two and connected to the oil pipe port, a connecting pipe four located at one end of the adapter two, a ball groove two opened inside the connecting pipe three, a pressure ball two located inside the ball groove two, a pressure sleeve two sleeved on the outside of the pressure ball two, a support ring two located at one end of the pressure sleeve two, a spring two located at one end of the support ring two, and an inner conical sleeve two located on the inner wall of the pressure sleeve two and in contact with the pressure ball one, with the inner wall being conical. as well as; Rotating structure one includes an adapter one located at one end of connector four, a connector one located at one end of the adapter and inserted into connector four, a connector two located at one end of adapter one, a sleeve one sleeved on the upper outer side of connector four and fixed at the lower end of the adapter, a ball groove one opened inside the sleeve one, a pressure bead one located inside the ball groove one, a pressure sleeve one sleeved on the outer side of the sleeve one, a support ring one located on the inner wall of the pressure sleeve one, a spring one located at one end of the support ring one, and an inner conical sleeve one located on the inner wall of the pressure sleeve one and in contact with the pressure bead two, with the inner wall being conical.

[0006] Furthermore, one end of the adapter is provided with a sleeve two that is sleeved on the outside of the pressure sleeve two, one end of the spring two is connected to the side of one end of the adapter two, and the spring two is located between the sleeve two and the connecting pipe three. Specifically, sleeve two limits spring two during the extension and retraction process to prevent spring two from shifting outward, and at the same time, it is used to shield the stroke of sleeve two.

[0007] Furthermore, the ball grooves are arranged in a ring array inside the connector three, and the outer wall of the oil pipe port is provided with a ring-shaped raceway two that rolls and fits against the outer wall of the pressure ball two. Specifically, the pressure beads are arranged in a ring array and pressed against the inner wall of the raceway, and the adapter rotates in accordance with this rolling support relationship.

[0008] Furthermore, the outer wall of the oil pipe port is fitted with multiple sets of sealing rings II, and the inner wall of the connecting pipe III is provided with an annular groove II for engaging and installing with the sealing rings; Specifically, when the second adapter rotates, it rotates inside the second annular groove via the second sealing ring, ensuring a tight seal during rotation and preventing leakage of the pressure medium.

[0009] Furthermore, the ball grooves are arranged in a ring array inside the sleeve, the outer wall of the pressure sleeve is provided with anti-slip texture, and one end of the spring is provided with a top ring connected to the outer wall of the sleeve. Specifically, the anti-slip texture improves the sealing performance during gripping, and the top ring is supported by a pair of springs, so that the pressure sleeve and the inner cone sleeve are elastically supported, and then elastically supported on the outer wall of the pressure ball.

[0010] Furthermore, the outer wall of the first connecting pipe is fitted with multiple sets of sealing rings, the outer wall of the fourth connecting pipe is provided with multiple sets of ring grooves that are snapped and installed with the sealing rings, and the outer wall of the fourth connecting pipe is provided with a raceway for rolling support of the pressure ball. Specifically, the sealing ring rotates inside the annular groove to ensure the sealing performance when the connector rotates. At the same time, the pressure beads distributed in an annular array provide multi-point annular array pressure for the connector. The pressure beads rotate inside the raceway to provide a stable rotation support for the adapter.

[0011] Furthermore, the adapter has a storage slot at its upper end, a connecting rope at its upper end, and a sealing plug at one end of the connecting rope. Specifically, the storage slot and sealing plug are assembled for storage. The sealing plug snaps into the second opening of the connecting pipe to seal the second opening and provide protection when not in use.

[0012] (ii) Beneficial effects

[0013] Compared with the prior art, the advantages of this invention are: In this invention, the oil pipe port of the hydraulic wrench is connected to adapter one for up / down rotation, and adapter two rotates clockwise / counterclockwise with adapter one. The rotating parts are sealed by a seal to prevent leakage of the pressure medium. At the same time, through the cooperation of pressure ball two and spring two, the inner cone sleeve two is driven by the elastic support pressure sleeve two to squeeze pressure ball two. After pressure ball two is pressed and rolled inside the raceway two, the oil pipe port installed by insertion and the connecting pipe three achieves insertion and sealing. The up and down rotation can adapt to the working requirements of the hydraulic wrench at different heights and tilt angles, such as bolting high-altitude pipelines and fastening equipment in low-ceilinged spaces. At the same time, through the cooperation of pressure ball one and spring one, the pressure sleeve one with elastic support drives the inner cone sleeve one to squeeze pressure ball one. After pressure ball one is pressed and rolled inside the raceway one, the plug-in pipe one and pipe four achieve plug-in sealing. The forward and reverse rotation can flexibly adjust the direction of the oil pipe, avoiding deformation or joint pulling caused by forced bending of the oil pipe. It is especially suitable for working conditions with multiple bolts densely arranged, such as flanges and pressure vessel end caps. The working point can be switched without frequently adjusting the overall position of the wrench. Meanwhile, during installation, simply align the connector with the interface and insert it; the elastic clamping of the pressure ball will secure it, significantly reducing assembly time. During maintenance, the component can be pulled out simply by overcoming the spring force, reducing maintenance costs and downtime.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please see Figure 1-6 As shown, this embodiment is a rotatable oil pipe joint and a multi-angle adaptive hydraulic wrench, including a wrench body and an oil pipe port 101 at one end of the wrench body 100. Rotating structure 2 300 includes an adapter 2 301 located outside the oil pipe port 101, a connecting pipe 3 302 located at one end of the adapter 2 301 and connected to the oil pipe port 101, a connecting pipe 4 310 located at one end of the adapter 2 301, a ball groove 2 303 opened inside the connecting pipe 3 302, a pressure ball 2 308 located inside the ball groove 2 303, a pressure sleeve 2 306 sleeved on the outside of the pressure ball 2 308, a support ring 2 311 located at one end of the pressure sleeve 2 306, a spring 2 309 located at one end of the support ring 2 311, and an inner conical sleeve 2 307 located on the inner wall of the pressure sleeve 2 306 and in contact with the pressure ball 1 213 with a conical inner wall. One end of adapter 2 301 is provided with sleeve 2 313 which is sleeved on the outside of pressure sleeve 2 306. One end of spring 2 309 is connected to the side of one end of adapter 2 301, and spring 2 309 is located between sleeve 2 313 and pipe 3 302. Ball groove 2 303 is distributed in a ring array inside the connector 302, and the outer wall of the oil pipe port 101 is provided with a ring-shaped raceway 2 304 that rolls and fits against the outer wall of the pressure ball 2 308. Multiple sets of sealing rings 312 are sleeved on the outer wall of the oil pipe port 101, and the inner wall of the connecting pipe 302 is provided with a ring groove 305 for engaging with the sealing rings. The rotating structure 2300 is used; The wrench body provides the installation base for the whole, and the oil pipe port 101 at one end directly serves as the reference component for rotation adjustment. The adapter 2 301 realizes angle adjustment and power transmission through the cooperation of multiple components. The pipe 3 302 and pipe 4 310 respectively undertake the functions of oil pipe connection and medium conduction. The components form a linkage through nesting, snap-fit, rolling fit and other methods to ensure stable hydraulic oil transmission and reliable angle locking during the adjustment process. When the operation requires adjusting the oil pipe route, such as to avoid obstacles in narrow spaces or to adapt to inclined bolts, the operator applies external force to the oil pipe or adapter 301. At this time, the raceway 304 on the outer wall of the oil pipe port 101 and the pressure ball 308 in the ball groove 303 inside the connector 302 form a rolling fit. The pressure ball 308 rolls along the circular trajectory of the raceway 304, causing the adapter 301 to rotate 360° clockwise or counterclockwise around the axis of the oil pipe port 101. At the same time, the connector 302 rotates synchronously with the adapter 301, and the connector 4 310 at one end of it maintains a stable connection with the external oil pipe, ensuring that the hydraulic oil transmission channel is always unobstructed and avoiding interruption of medium transmission during the adjustment process. During the adjustment process, spring 2 309 is always in a pre-compressed state. One end of it is fixedly connected to the side of adapter 2 301, and the other end generates a continuous axial thrust on pressure sleeve 2 306 through support ring 2 311. After pressure sleeve 2 306 is subjected to thrust, it drives inner conical sleeve 2 307 with conical inner wall to squeeze towards pressure ball 2 308. The conical structure of inner conical sleeve 2 307 converts the axial thrust into radial pressure on pressure ball 2 308, so that pressure ball 2 308 fits tightly against the inner wall of raceway 2 304. This linkage of spring thrust, conical conversion, and pressure ball locking can achieve instant locking at any adjustment angle, which not only avoids angle deviation caused by vibration and hydraulic shock during rotation, but also does not require additional tools for fixing, ensuring that the relative position of oil pipe port 101 and adapter 2 301 is stable after adjustment. While achieving angle adjustment, the rotating structure 300 must ensure the leak-free transmission of high-pressure hydraulic oil. Its sealing and medium conduction mechanism is as follows: Multiple sets of sealing rings 312 sleeved on the outer wall of the oil pipe port 101 form a snap-fit ​​fit with the annular groove 305 opened on the inner wall of the connecting pipe 302. After the sealing ring 312 is embedded in the annular groove 305, its outer wall is tightly fitted with the inner wall of the annular groove 305, and its inner wall is tightly fitted with the outer wall of the oil pipe port 101, forming the first static sealing defense line to block the leakage of hydraulic oil from the gap between the oil pipe port 101 and the connecting pipe 302. At the same time, the tight fit between the inner cone sleeve 307 and the pressure ball 308, and the rolling seal between the pressure ball 308 and the raceway 304, form a dynamic sealing supplement during the rotation adjustment process. Even when the angle changes, the fit of the sealing surface can be maintained by elastic pressure to avoid leakage due to gaps. Hydraulic oil enters from the external oil pipe into the fourth connector 310, flows into the third connector 302 through the internal channel of the second adapter 301, and then enters the oil pipe port 101 through the mating gap between the third connector 302 and the oil pipe port 101. Finally, it is transmitted to the hydraulic drive component inside the wrench body to provide torque power to the wrench. In the entire transmission path, the relative rotation between the third connector 302 and the oil pipe port 101 will not change the conduction cross section of the channel. The fixed connection between the second adapter 301 and the fourth connector 310 and the third connector 302 also ensures that the channel is not misaligned, ensuring the continuity and pressure stability of hydraulic oil transmission and avoiding pressure loss caused by channel deformation or misalignment. The sleeve 313 at one end of the second adapter 301 is sleeved on the outside of the pressure sleeve 306. On the one hand, it can isolate external dust and impurities from entering the core components such as the pressure ball 308 and the spring 309, and prevent foreign objects from affecting the rolling fit and elastic performance. On the other hand, it provides guidance for the axial movement of the pressure sleeve 306, preventing the pressure sleeve 306 from shifting under the spring thrust, ensuring that the inner cone sleeve 307 exerts uniform pressure on the pressure ball 308, and improving locking stability. The ball groove 303 is distributed in a ring array inside the pipe 302, and the corresponding pressure ball 308 and pressure sleeve 306 are also distributed in a ring. This structure makes the radial locking force on the oil pipe port 101 evenly distributed in the circumferential direction, avoiding deformation of the oil pipe port 101 or wear of the raceway 304 due to excessive local force, extending the service life of the component, and ensuring smoothness during rotation adjustment, avoiding jamming due to uneven force. The rotating structure 2.300 effectively solves the pain points of traditional hydraulic wrenches, adapting to complex working conditions. It addresses the issues of interference and misalignment of fixed oil pipe joints in narrow spaces or with inclined bolts. 360° rotation adjustment avoids obstacles, eliminating the need for repeated wrench adjustments. It also solves the problems of poor sealing, hydraulic oil leakage, and pressure loss associated with traditional rotating joints, with double sealing ensuring no leakage and maintaining stable pressure. Furthermore, it resolves the conflict between ease of adjustment and locking stability, with elastic locking requiring no tools and preventing vibration-induced deviation. It also addresses issues of component wear and adjustment jamming, with a ring-shaped distribution design ensuring balanced force distribution and extending service life. Ultimately, it improves work efficiency and reduces maintenance costs.

[0024] Example 2

[0025] Please see Figure 1-6 As shown, and; Rotating structure 200 includes an adapter 201 located at one end of connector 310, a connector 202 located at the end of adapter 201 and inserted into connector 310, a connector 218 located at one end of adapter 201, a sleeve 204 sleeved on the upper side of connector 310 and fixed at the lower end of adapter 201, a ball groove 205 opened inside sleeve 204, a pressure bead 213 located inside ball groove 205, a pressure sleeve 207 sleeved on the outside of sleeve 204, a support ring 210 located on the inner wall of pressure sleeve, a spring 211 located at one end of support ring 210, and an inner conical sleeve 209 located on the inner wall of pressure sleeve 207 and in contact with pressure bead 308 and having a conical inner wall. The ball grooves 303 are arranged in a ring array inside the sleeve 204. The outer wall of the pressure sleeve 207 is provided with anti-slip textures 208. One end of the spring 211 is provided with a top ring 214 that connects to the outer wall of the sleeve 204. The outer wall of the first connector 202 is fitted with multiple sets of sealing rings 212, the outer wall of the fourth connector 310 is provided with multiple sets of ring grooves 203 that are snapped and installed with the sealing rings 212, and the outer wall of the fourth connector 310 is provided with a raceway 206 that provides rolling support for the pressure ball 213. The adapter 201 has a storage slot 215 at the upper end, a connecting rope 216 at the upper end, and a sealing plug 217 at one end of the connecting rope 216. The rotating structure 1200 is used; When the pipeline route needs to be adjusted during operation, the operator applies external force to adapter 201 or connector 218. At this time, the raceway 206 on the outer wall of connector 4 310 and the pressure ball 213 in the ball groove 205 inside the sleeve 204 form a rolling fit. The pressure ball 213 rolls along the circular trajectory of the raceway 206, causing adapter 201 to rotate 360° clockwise or counterclockwise around the axis of connector 4 310. Simultaneously, it drives connector 202 and connector 218 to adjust their direction. Different operating angles can be adapted without moving the main body of the wrench. During the adjustment process, spring 211 is always in a pre-compressed state, and one end of it is connected to the top ring 2. 14. One end is fixed to the outer wall of the sleeve 204, and the other end generates a continuous axial thrust on the pressure sleeve 207 through the support ring 210. After the pressure sleeve 207 is subjected to the thrust, it drives the inner conical sleeve 209 with a conical inner wall to squeeze towards the pressure ball 213. The conical structure of the inner conical sleeve 209 converts the axial thrust into the radial pressure on the pressure ball 213, so that the pressure ball 213 fits tightly against the inner wall of the raceway 206. This linkage of spring thrust, conical conversion and pressure ball locking can achieve instant locking at any adjustment angle, avoid angle deviation caused by vibration and hydraulic shock, and does not require additional tools for fixing, ensuring the stability of the position after adjustment. Multiple sets of sealing rings 212 fitted onto the outer wall of connector 202 form a snap-fit ​​fit with the annular groove 203 on the outer wall of connector 310. After the sealing rings 212 are embedded in the annular groove 203, their inner and outer walls are tightly fitted with the outer wall of connector 202 and the inner wall of annular groove 203, respectively, forming the first static sealing line to prevent hydraulic oil from leaking from the insertion gap between connector 202 and connector 310. At the same time, the tight rolling fit between pressure ball 213 and raceway 206 and the squeezing seal between inner cone sleeve 209 and pressure ball 213 form a dynamic sealing supplement during rotation. Even if the angle changes, the sealing surface fit can be maintained by elastic pressure to prevent leakage. Hydraulic oil enters from the external system through pipe 4 310, and is then diverted through the internal channel of adapter 1 201 to pipe 1 202 and pipe 2 218, before being transmitted to the wrench hydraulic drive assembly to provide torque power to the wrench. Throughout the entire path, the rotation of adapter 1 201 does not change the channel conduction cross section. The plug-in connection between pipe 1 202 and pipe 4 310 ensures continuous hydraulic oil transmission and stable pressure, avoiding pressure loss that could affect torque output. According to the requirements of the operation scenario, hold the pressure sleeve 207 with both hands and gently push the adapter 201 to make the pressure ball 213 roll along the raceway 206, driving the connecting pipe 202 and connecting pipe 218 to rotate to the target angle. During the process, the angle adaptation can be observed in real time until obstacles are avoided and the bolts are aligned. Then, release the pressure sleeve 207. The spring 211 pushes the inner cone sleeve 209 through the support ring 210 and the pressure sleeve 207 to squeeze the pressure ball 213, thereby locking the angle. After the operation is completed, if the device needs to be idle, remove the sealing plug 217 in the storage slot 215 to seal the connection. The 218 port of the second pipe solves the problems of poor angle adaptation and easy interference of fixed oil pipe joints in narrow spaces and dense bolt scenarios. The 360° rotation adjustment eliminates the need to move the wrench, improving work efficiency. It solves the problems of sealing failure and hydraulic oil leakage of traditional rotary joints, and resolves the contradiction between adjustment convenience and locking stability. The elastic pressure ball locking requires no tools, prevents vibration and deviation, and ensures accurate torque. The sealing plug 217 and protective structure solve the problem of "impurities entering the channel" when idle, extending the component life. It is simple to operate and easy to maintain, adaptable to a variety of complex working conditions, and improves the practicality and reliability of the wrench.
