DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a hydraulic instrument quick connector, including a main body 1; in order to solve the problem that a large installation space needs to be reserved when installing the existing quick connector, when the equipment is in a corner, the existing quick connector cannot be quickly installed or even cannot be installed due to the narrow installation environment, the main body 1 is provided with a rotating mechanism 2 and a quick link mechanism 3; the rotating mechanism 2 includes a spherical linking tube 200, the spherical linking tube 200 is rotatably installed in the main body 1, a linking tube sealing ring 201 is installed inside the main body 1, the spherical linking tube 200 and the linking tube sealing ring 201 are adapted, a rotating cover 203 is rotatably installed on one side of the main body 1, a rubber ring 202 is installed inside the rotating cover 203, a bracket 204 is installed on the outside of the rotating cover 203, a linking cylinder 205 is installed on the two brackets 204, a paddle 206 and a block 207 are installed at both ends of the two linking cylinders 205, springs 208 are installed on the two blocks 207, and the outer side of the main body 1 is opened. A card slot 209 is provided, and the card slot 209 is adapted to the card block 207. An instrument pipeline 211 is installed on one side of the spherical connecting tube 200. The rotating cover 203 is located between the main body 1 and the instrument pipeline 211. Before using the hydraulic instrument quick interface, the rotating cover 203 is first loosened, and the rubber ring 202 in the rotating cover 203 will lose the friction force on the spherical connecting tube 200. Then the spherical connecting tube 200 is rotated to a suitable installation position, and then the rotating cover 203 is rotated to make the rubber ring 202 and the spherical connecting tube 200 meet. The spherical connecting tube 200 contacts with the rubber ring 202, and the angle of the spherical connecting tube 200 is fixed by the friction between the spherical connecting tube 200 and the rubber ring 202. When the rotating cover 203 is twisted, the block 207 slides in the slot 209, so the rotating cover 203 will not fall off from the main body 1. Then the instrument is installed on the instrument pipe 211. By rotating the spherical connecting tube 200, the instrument can be installed at more angles, thereby avoiding the inability to install the instrument due to insufficient installation space.

[0023] The working principle is as follows: before using the hydraulic instrument quick interface, first loosen the rotating cover 203, the rubber ring 202 inside the rotating cover 203 will lose the friction force on the spherical connecting tube 200, then rotate the spherical connecting tube 200 to a suitable installation position, and then rotate the rotating cover 203 to make the rubber ring 202 contact with the spherical connecting tube 200, and fix the angle of the spherical connecting tube 200 through the friction force between the spherical connecting tube 200 and the rubber ring 202. In the process of twisting the rotating cover 203, the block 207 will slide in the slot 209, so that the rotating cover 203 will not fall off the main body 1, and then the instrument is installed on the instrument pipeline 211, and the spherical connecting tube 200 can be rotated. The instrument can be installed at more angles, thus avoiding the inability to install the instrument due to insufficient installation space; the main body 1 is connected with the equipment pipe 302, the main body block 307 and the equipment pipe slot 304 will be stuck under the action of the main body spring 308, and the main body sealing ring 301 and the equipment pipe sealing ring 303 inside the main body 1 and the equipment pipe 302 will also be squeezed against each other under the action of force to achieve a sealing effect. When disassembly is required, the main body paddle 306 is pushed outward, and the main body paddle 306 will drive the main body connecting cylinder 305 and the main body block 307 to move synchronously, so that the main body block 307 is separated from the equipment pipe slot 304. The connection and separation of the equipment can be completed without tools, which increases the work efficiency of the user.

A main body sealing ring 301 is provided in the main body 1, and the main body sealing ring 301 is adapted to the equipment pipeline 302: a main body connecting cylinder 305 is installed on the main body 1, and a main body paddle 306 and a main body block 307 are respectively installed on both sides of the two main body connecting cylinders 305, and the two main body blocks 307 are both installed with a main body spring 308. An equipment pipeline slot 304 is opened on the equipment pipeline 302, and the equipment pipeline slot 304 and the main body block 30 7 is adapted, the main body 1 is sleeved with the equipment pipe 302, the main body block 307 and the equipment pipe slot 304 will be stuck under the action of the main body spring 308, and the main body sealing ring 301 and the equipment pipe sealing ring 303 inside the main body 1 and the equipment pipe 302 will also be squeezed against each other under the action of force to achieve a sealing effect. When it is necessary to disassemble, the main body paddle 306 is pushed outward, and the main body paddle 306 will drive the main body connecting cylinder 305 and the main body block 307 to move synchronously, so that the main body block 307 is separated from the equipment pipe slot 304. No tools are required to complete the connection and separation of the equipment, thereby increasing the work efficiency of the user. The remaining features are the same as those of Example 1.
