Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic clamping sleeves, and more specifically, to a hydraulic clamping sleeve capable of preventing loosening. Background Art
[0002] Hydraulic ferrules are an important component in hydraulic systems. They are mainly used to connect pipes and fittings, protect the internal parts of hydraulic cylinders, prevent the pistons, seals and other parts inside the hydraulic cylinders from leaking or being damaged due to wear during use, and prevent foreign matter such as impurities from entering, causing damage to parts and failure of the hydraulic system, thereby ensuring the normal operation of the hydraulic system.
[0003] Hydraulic ferrule pipe fittings usually consist of three parts: a fitting body, a ferrule and a nut. When the hydraulic ferrule and the nut are inserted into the fitting body after being sleeved on the steel pipe, and the nut is tightened, the outer side of the front end of the hydraulic ferrule fits against the conical surface of the fitting body, and the inner edge bites into the seamless steel pipe evenly to form an effective seal. Since this type of hydraulic ferrule relies on the nut to press against the rear end of the fitting body to achieve pipe cutting sealing, whether the hydraulic ferrule is loose depends on whether the nut is loose. The nut of this type of hydraulic ferrule is only fixed to the outer surface of the ferrule by threaded rotation. Once vibration occurs, the nut will loosen, thereby causing the hydraulic ferrule to loosen, so it needs to be improved. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a hydraulic clamping sleeve for preventing loosening, which has the advantage of preventing a nut from loosening.

[0029] When the operator installs the nut body 4, the nut body 4 will rotate and move inward, thereby driving the pawl 7 to move inward, and then the pawl 7 can gradually engage with the ratchet 5. After the nut body 4 is tightened, the pawl 7 is engaged with the ratchet 5, and the nut body 4 can no longer rotate in the opposite direction, so that the nut body 4 can be more stably installed on the outer surface of the sleeve body 1, avoiding the nut body 4 from loosening.
[0030] A fixing nut 13 is fixedly installed in the middle of the ferrule body 1 , and fixing rings 14 located on the left and right sides of the fixing nut 13 are fixedly installed on the outer surface of the ferrule body 1 .
[0031] By providing the fixing ring 14, the fixing ring 14 can play a role of limiting.
[0032] Among them, a limiting plate 15 is fixedly installed on the outer side of the fixing ring 14, the bottom of the limiting plate 15 is fixedly connected to the outer surface of the ferrule body 1, and the outer surface of the limiting plate 15 is movably sleeved with a mounting ring 16, and the inner surface of the mounting ring 16 is movably sleeved with the outer surface of the ferrule body 1.
[0033] When the mounting ring 16 is sleeved on the outer surface of the limiting plate 15 , it will limit the mounting ring 16 , thereby preventing the mounting ring 16 from rotating.
[0034] Among them, a fixing plate 17 is fixedly installed on the left and right sides of the ferrule body 1, a second spring 18 is fixedly installed on the inner side of the fixing plate 17, and the other end of the second spring 18 is fixedly connected to a push plate 19, the inner surface of the push plate 19 is movably connected to the outer surface of the ferrule body 1, and the outer surface of the push plate 19 is movably connected to the outer surface of the mounting ring 16.

[0042] The working principle and use process of this utility model:
[0043] After the operator puts the joint body 2 and the nut body 4 on the outer surface of the pipe 3, the pipe 3 is inserted into the interior of the ferrule body 1, and then the nut body 4 is rotated and installed. The inner surface of the nut body 4 will abut the outer end of the joint body 2 and push the joint body 2 forward, so that after the joint body 2 enters the interior of the ferrule body 1, it cuts into the interior of the pipe 3 under the guidance of the inclined surface inside the ferrule body 1, thereby achieving an effective sealing effect. When the nut body 4 rotates forward, the pawl 7 will gradually engage with the ratchet 5, so that after the nut body 4 is installed, the pawl 7 is engaged with the ratchet 5, so that the nut body 4 cannot rotate in the opposite direction, thereby preventing the nut body 4 from loosening, thereby making the connection more stable and improving the use effect of the device. The operator can pull the pull ring 11 upwards so that the connecting rope 10 drives the ratchet 7 to rotate with the fixed shaft 6 as the axis, thereby being able to release the engagement between the pawl 7 and the ratchet 5, so that the nut body 4 can be rotated in the opposite direction, and then the nut body 4 can be disassembled.
[0044] Due to the design of the first support plate 20 and the second support plate 21, the first support plate 20 and the second support plate 21 can support the entire ferrule body 1 to avoid the ferrule body 1 from dragging on the ground after being connected to the pipe 3. When the bottom of the first support plate 20 and the second support plate 21 are not facing directly downward, the operator can push the mounting ring 16 outward to make the mounting ring 16 break away from the contact with the limit plate 15, so that the mounting ring 16 can rotate. At this time, the operator can adjust the bottom of the first support plate 20 and the second support plate 21 to a downward state by rotating the mounting ring 16, thereby improving the flexibility of use of the device.
