[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

This coupling includes a main body and a hydraulic expansion sleeve disposed inside the main body with a clearance fit. The hydraulic expansion sleeve comprises an outer sleeve and an inner sleeve, which are welded together, and an annular oil cavity is provided between them. The outer sleeve has an oil inlet and an oil outlet, which are connected to the annular oil cavity. This technical solution addresses the problems of difficult disassembly, easy damage during disassembly, and severe wear during use in existing couplings.

[0004] However, the above-mentioned coupling still has the following problems: it is inconvenient to disassemble and assemble, making it difficult to disassemble and assemble quickly, and it cannot be buffered during use, which can cause damage to the coupling. Utility Model Content

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 This utility model provides a technical solution for a split-type quick-release hydraulic coupling: A split-type quick-release hydraulic coupling includes a main body 1 and a main body 2. A fixing sleeve 3 is fixedly connected to the side of the main body 1 that is away from the main body 2. A guide hole 10 with symmetrical upper and lower sides is opened on one side of the main body 1. A support rod 4 with symmetrical upper and lower sides is fixedly connected to one side of the main body 2. A fixing block 5 is fixedly connected to one end of each support rod 4. Limiting components 7 for fixing the support rod 4 are provided on both the upper and lower sides inside the main body 1. Four corners on one side of the main body 2 are provided with features for fixing the coupling. The damping component 8, which provides a buffering and shock absorption function, and the top of the fixing sleeve 3 are both equipped with locking components 9 that can fix the installed shaft. The four corners of the side of the main body 1 are provided with positioning grooves 11. The damping sleeves 81 are slidably connected inside the positioning grooves 11. By inserting the damping sleeves 81 into the positioning grooves 11, they can play a role in quick positioning when installing the coupling, avoiding deviation during installation. The inside of the main body 1 and the main body 2 are both provided with limit slots 6. The limit slots 6 can facilitate the installation of the shaft and prevent relative rotation between the shaft and the coupling.

[0024] Please see Figure 2The limiting component 7 includes a support groove 71, which is opened on the upper and lower sides inside the main body 1. A movable frame 72 is movably connected inside the support groove 71. A limiting block 74 is fixedly connected to one side of the movable frame 72. One end of the support rod 4 passes through the guide hole 10 and is inserted into the inside of the support groove 71. The limiting block 74 is locked on one side of the fixed block 5. A first spring 75 is fixedly connected to the middle of the bottom wall of the support groove 71. The top end of the first spring 75 is fixedly connected to the movable frame 72. A pressing block 73 is fixedly connected to one end of the movable frame 72. Through the pushing action of the first spring 75 on the movable frame 72, the limiting block 74 can be driven to be inserted under the fixed block 5, so that the shock-absorbing sleeve 81 is inserted into the inside of the positioning groove 11, which can keep the support rod 4 stable inside the support groove 71.

[0025] Please see Figure 3 The vibration damping assembly 8 includes a damping sleeve 81, which is fixedly connected to the four corners of the side of the main body 2. A damper 82 is fixedly connected to the inner wall of the damping sleeve 81. A second spring 83 is fixedly connected to one side of the damper 82. A buffer rod 84 is fixedly connected to one end of the second spring 83. The damping sleeve 81 is inserted into the positioning groove 11. During the rotation of the coupling, the vibration of the shaft is transmitted to the inside of the coupling. Through the combined action of the damper 82 and the second spring 83, the vibration energy can be absorbed and dissipated, thereby reducing the impact of vibration on the coupling and preventing damage to the coupling.

[0026] Please see Figure 4 The locking assembly 9 includes a support base 91, which is fixedly connected to the middle of the top of the fixed sleeve 3. A threaded sleeve 92 is fixedly connected to the bottom of the support base 91. A locking rod 93 is vertically connected inside the support base 91 and is threadedly connected to the inside of the threaded sleeve 92. By rotating the locking rod 93 and the threaded sleeve 92, the locking rod 93 can clamp and fix the shaft installed therein, preventing relative rotation between the shaft and the coupling.

[0027] The working principle and usage process of this utility model are as follows: The main body 1 and the main body 2 are connected, so that the support rods 4 are respectively inserted into the guide holes 10. The shock-absorbing sleeves 81 are respectively aligned with different positioning slots 11. Through the pushing action of the first spring 75 on the movable frame 72, the limiting block 74 can be driven to insert below the fixed block 5, so that the shock-absorbing sleeves 81 are inserted into the positioning slots 11. This allows the support rods 4 to remain stable inside the support slots 71. When it is necessary to disassemble the coupling, pressing the pressing blocks 73 on both sides simultaneously can drive the movable frame 72 to move inward, thus enabling the coupling to be disassembled. The first spring 75 is compressed, thereby causing the limiting block 74 to disengage from below the fixed block 5, releasing the position restriction on the fixed block 5. Then, the main body 2 is pulled to remove the support rod 4 from the inside of the guide hole 10, completing the separation of the coupling. The shock-absorbing sleeve 81 is inserted into the positioning groove 11. During the rotation of the coupling, the vibration of the shaft is transmitted to the inside of the coupling. Through the combined action of the damper 82 and the second spring 83, the vibration energy can be absorbed and dissipated, thereby reducing the impact of vibration on the coupling and preventing damage to the coupling.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
