Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe connector technology, specifically a hydraulic pipe connector with a reinforced structure. Background Technology

[0002] For example, Chinese patent document 200820116250 discloses a manual hydraulic pipe-connecting tool. This tool utilizes the pressure generated by a manual hydraulic pump to tighten and press a pipe collar onto the pipe connector using a "tightening collar method." The tool's fixed and sliding clamping heads for tightening the collar are detachable, replaceable, and assembleable. A thrust-opening cone claw can also be installed at its front end to expand the pipe, allowing the two steps of expanding the pipe and tightening the collar to be completed using only a single manual hydraulic pump.

[0003] In existing publicly available technologies, hydraulic pipe fittings are connected by using a manual hydraulic pump to generate pressure, which tightens the pipe collar and pushes it onto the pipe fitting. Generally, the probability of damage to the hydraulic pipe is higher than that of the fitting, and the replacement frequency is also higher. However, when the hydraulic pipe is replaced multiple times, the threaded connection will wear down the threads on the outer surface of the threaded tube. Wear on the outer surface of the threaded tube can easily lead to an unstable connection, causing leakage of liquid or gas inside the hydraulic pipe. Especially when the internal pressure of the fitting is high, it is more likely to cause the seal at the threaded tube to be damaged, causing the fitting to detach from the hydraulic pipe. Utility Model Content

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a hydraulic pipe connector with a reinforced structure, the hydraulic pipe connector with a reinforced structure comprising:

[0023] A right sleeve 2 is rotatably installed on one side of the outer wall of the intermediate tube 4. The right sleeve 2 rotates through the annular groove 16. A raceway 8 is opened on one side of the inner wall of the right sleeve 2. The raceway 8 is used to insert the ball bearing 7. Several ball bearings 7 are fixedly installed on one side of the outer wall of the raceway 8. The ball bearings 7 need to be removed when the threaded tube 17 is not loose. The sleeve includes the right sleeve 2 and the left sleeve 6. Pressing down the sleeve and then rotating it will drive the ball bearing 7 through the connecting tube 1 to achieve more convenient disassembly. At the same time, the ball bearing 7 plays a secondary role in fixing.

[0024] Several moving cavities 10 are formed on one side of the inner wall of the intermediate tube 4. The moving cavities 10 are used to hold moving parts, including triangular blocks 11, rotating cylinders 12, springs 9, and pressing blocks 14. Rotating cylinders 12 are fixedly installed on one side of the outer wall of the moving cavities 10. Triangular blocks 11 are rotatably installed on the outer surface of the rotating cylinders 12. Pressing blocks 14 are slidably installed on one side of the outer wall of the triangular blocks 11. Pressing blocks 14 cause the triangular blocks 11 to rotate. Springs 9 are fixedly installed on one side of the outer wall of the triangular blocks 11. Springs 9 provide power to the triangular blocks 11. When disassembly is required, press the pressing blocks 14 first. Pressing blocks 14 cause the triangular blocks 11 to rotate around the rotating cylinders 12. At this time, springs 9 are compressed, and the damaged threaded tube 17 can be disassembled and replaced with a new threaded tube 17, so that the connector can be reused.

[0025] A left sleeve 6 is rotatably installed on one side of the outer wall of the intermediate tube 4. The left sleeve 6 rotates through the annular groove 16. A raceway 8 is opened on one side of the inner wall of the left sleeve 6. Several balls 7 are fixedly installed on one side of the outer wall of the raceway 8.

[0026] The outer circular surfaces at both ends of the intermediate tube 4 are provided with annular grooves 16 to facilitate the rotation of the sleeve and the disassembly of the connected tube 1. The annular grooves 16 allow the sleeve to rotate. A right sleeve 2 and a left sleeve 6 are slidably installed on one side of the outer wall of the annular grooves 16. A sealing ring 5 is fixedly installed on one side of the inner wall of both the right sleeve 2 and the left sleeve 6. The connected tube 1 is fixedly installed on one side of the outer wall of the sealing ring 5.

[0027] A groove 13 is provided on one side of the outer wall of the motion cavity 10. The groove 13 is used for the sliding of the slider 15. The slider 15 is slidably installed on one side of the outer wall of the groove 13. The slider 15 is welded to one side of the outer wall of the pressing block 14. The slider 15 is fixedly installed on one side of the outer wall of the pressing block 14. Threaded tubes 17 are movably installed on one side of the outer wall of the triangular block 11. Connected tubes 1 are fixedly installed on one side of the outer wall of the threaded tube 17. The end of the spring 9 away from the triangular block 11 is fixedly installed on one side of the outer wall of the motion cavity 10. When the outer wall of the threaded tube 17 passes through the inclined surface of the triangular block 11, the triangular block 11 rotates clockwise due to the compression of the spring 9 and the rotation of the rotating cylinder 12. When the threaded tube 17 passes through the inclined surface of the triangular block 11, the compressed spring 9 stretches and lifts the triangular block 11 to achieve the positioning of the threaded tube 17.

[0028] When this device is in operation, the threaded tube 17 is first connected to the outer wall of one side of the connected tube 1 via a threaded connection. Then, the threaded tube 17 is inserted into the intermediate tube 4. When the outer wall of one side of the threaded tube 17 passes the inclined surface of the triangular block 11, the triangular block 11 rotates clockwise due to the compression of the spring 9 and the rotation of the rotating cylinder 12. When the threaded tube 17 passes the inclined surface of the triangular block 17, the compressed spring 9 stretches and lifts the triangular block 17 to achieve positioning of the threaded tube 17. When the threaded tube 17 moves, the ball 7 on the sleeve enters the groove of the connected tube 1 to achieve re-fixation. When the thread is damaged, the fixing of the triangular block 17 and the ball 7 prevents the joint from falling off the connected tube 1. When disassembly is required, first press the pressing block 14. The pressing block 14 causes the triangular block 17 to rotate around the rotating cylinder 12. At this time, the spring 9 is compressed, and the damaged threaded tube 17 can be removed and replaced with a new threaded tube 17 to achieve reuse of the joint.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
