Description

Technical Field

[0001] This utility model relates to the field of mechanical connection components technology, specifically a novel floating joint. Background Technology

[0002] Floating joints, as key components connecting cylinders and workpieces, are of great significance in practical applications. When the direction of the cylinder's driving force is not in a straight line with the point of force application, the piston rod is prone to deformation. Floating joints can absorb the offset of the workpiece's parallelism with the cylinder, achieving a flexible connection, ensuring that the thrust is not reduced, protecting the cylinder's seals, and extending the cylinder's lifespan.

[0003] Patent application number 201921815801.8 discloses a floating joint, including a housing with an inner cavity, a retainer assembly disposed in the inner cavity of the housing, a ball joint mounted on the retainer assembly, and a connecting rod integrally formed with the ball joint. The housing has a threaded hole communicating with the inner cavity, and the connecting rod extends out of the threaded hole. The threaded hole is threadedly connected to a clamping assembly for clamping the retainer assembly. The ball joint is rotatably connected to the retainer assembly.

[0004] During maintenance, the floating joint is connected to the threaded hole by the clamping component. By disassembling the clamping component, the seat assembly and ball joint can be removed from the inner cavity of the housing, which facilitates the replacement and repair of components and improves the service life of the floating joint. However, special tools are required to disassemble the clamping component, and the replacement is relatively cumbersome, which cannot meet the current needs. Utility Model Content

[0005] The purpose of this invention is to provide a novel floating joint to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel floating joint, comprising a housing, an oil nozzle, a first retaining seat, a ball joint, a second retaining seat, and a disassembly device. The oil nozzle is disposed on the side of the housing, the first retaining seat is disposed inside the housing, the ball joint is disposed inside the housing, the second retaining seat is disposed inside the housing, and the disassembly device is disposed inside the housing.

[0007] The disassembly device comprises an annular disc, a first movable shaft, a first spring, a first fixing ring, a first fixing block, a second movable shaft, a second spring, a second fixing ring, a second fixing block, a connecting plate, and a limiting post. The annular disc is slidably installed inside the housing. The first movable shaft is slidably installed inside the housing. The first spring is sleeved on the surface of the first movable shaft. The first fixing ring is fixedly installed on the surface of the first movable shaft. The first fixing block is fixedly installed at one end of the first movable shaft. The second movable shaft is slidably installed inside the housing. The second spring is sleeved on the surface of the second movable shaft. The second fixing ring is fixedly installed on the surface of the second movable shaft. The second fixing block is fixedly installed at one end of the second movable shaft. The connecting plate is fixedly installed at the other end of the second movable shaft. The limiting post is fixedly installed on the side of the connecting plate.

[0008] Preferably, the end faces of the first and second card holders facing the spherical connector are spherical surfaces adapted to the spherical connector.

[0009] Preferably, a push plate is fixedly installed at the other end of the first moving shaft.

[0010] Preferably, one end of the first spring is fixedly connected to the housing, and the other end of the first spring is fixedly connected to the first fixing ring, and the first spring is provided for resetting the first fixing ring.

[0011] Preferably, the opposing surfaces of the first fixing block and the second fixing block are both set as inclined surfaces, which allows the first fixing block to slide on the surface of the second fixing block.

[0012] Preferably, one end of the second spring is fixedly connected to the housing, and the other end of the second spring is fixedly connected to the second fixed ring, with the second spring provided for resetting the second fixed ring.

[0013] Preferably, the annular disk has a limiting groove inside that matches the limiting post. The second moving shaft, the second spring, the second fixing ring, the second fixing block, the connecting plate, and the limiting post are all in groups of one, and there are two groups symmetrically arranged on both sides of the first fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel floating joint drives the first moving shaft to move by pushing the push plate, which allows the first fixed block to slide on the surface of the second fixed block, and allows the second moving shaft to move, so that the connecting plate drives the limiting post to disengage from the limiting groove. The annular disc, the second card seat, the ball joint, and the first card seat can be taken out in sequence, and the first card seat, the ball joint, and the second card seat can be replaced. The replaced first card seat, ball joint, and second card seat are installed inside the housing, and then the annular disc is pressed against the side of the second card seat. The push plate is released, and under the action of the first spring and the second spring, the limiting post can enter the limiting groove, which can fix the annular disc and make replacement convenient.

The oil nozzle 2 is disposed on the side of the housing 1, the first retaining seat 3 is disposed inside the housing 1, the ball joint 4 is disposed inside the housing 1, and the second retaining seat 5 is disposed inside the housing 1. The end faces of the first retaining seat 3 and the second retaining seat 5 facing the ball joint 4 are spherical surfaces adapted to the ball joint 4. This arrangement allows the ball joint 4 to move on the surfaces of the first retaining seat 3 and the second retaining seat 5. The disassembly device 6 is disposed inside the housing 1.

[0023] The disassembly device 6 consists of an annular disc 601, a first moving shaft 602, a first spring 603, a first fixing ring 604, a first fixing block 605, a second moving shaft 606, a second spring 607, a second fixing ring 608, a second fixing block 609, a connecting plate 610, and a limiting post 611. The annular disc 601 is slidably installed inside the housing 1. The first moving shaft 602 is slidably installed inside the housing 1, and a push plate is fixedly installed at the other end of the first moving shaft 602. The first spring 603 is sleeved on the surface of the first moving shaft 602. The first fixing ring 604 is fixedly installed on the surface of the first moving shaft 602. One end of the first spring 603 is fixedly connected to the housing 1, and the other end of the first spring 603 is fixedly connected to the first fixing ring 604. The first spring 603 is provided for resetting the first fixing ring 604. The first fixing block 605 is fixedly installed at one end of the first moving shaft 602.
