Description

Technical Field

[0001] The utility model relates to the technical field of connecting devices, in particular to a hydraulically driven connecting device. Background Art

[0002] Existing hydraulic cylinder connectors generally use fixing nuts to achieve simple fixation and have a single fixing effect, so they can only be used to fix the hydraulic cylinder.

[0003] The existing Chinese patent with announcement number CN221347483U discloses a hydraulic cylinder connecting part, which specifically relates to the field of connecting parts, including a device body, and also includes: the middle end of the device body is provided with a fixed connecting device that can fix the hydraulic cylinder, which is used to stably fix the hydraulic cylinder on the upper end of the connecting part, thereby realizing convenient disassembly or installation; the lower end of the device body is provided with a flexible switching device that can convert the state of the hydraulic cylinder, which is used to automatically switch the connection state of the hydraulic cylinder, thereby realizing the effect of rotation or fixation, and therefore has a wider application.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device fixes the hydraulic cylinder by clamping the connecting block, but the orientation of the hydraulic cylinder is single when fixed and cannot be flexibly adjusted, which requires improvement; therefore, a hydraulically driven connecting device is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the present invention proposes a hydraulically driven connecting device.

An annular mounting bracket is installed on the outer side of the end, and the mounting bracket is fixedly connected to the fixing seat. The upper and lower parts of the mounting bracket are respectively fixedly connected with electric push rods, and the driving end of the electric push rod is fixedly connected with a clamping block. The fixing ear is connected to the fixing seat through a fixing component. When the hydraulic cylinder rotates, the connecting piece is synchronously driven to rotate. When the hydraulic cylinder needs to be fixed, the electric push rod is run, and the electric push rod drives the clamping block to be inserted into the clamping slot at the corresponding position, thereby clamping the connecting piece and fixing the position of the hydraulic cylinder, thereby achieving the effect of rotation or fixation. Compared with the existing technology, the direction of the hydraulic cylinder when fixed can be flexibly adjusted.

[0007] Preferably, the card block and the card slot are respectively arranged in a triangular shape.

The pin is inserted into the interior of the fixing hole by the elastic force of the spring, thereby locking the position of the sliding sleeve to achieve rapid and stable connection of the hydraulic cylinder. When the hydraulic cylinder needs to be disassembled, the pin is pulled outward and the sliding sleeve is pushed out of the slot to quickly disassemble the hydraulic cylinder.

The fixing ear 2 is connected to the fixed seat 3 through the fixing component 5. When the hydraulic cylinder 1 rotates, the connecting piece 41 is synchronously driven to rotate. When the hydraulic cylinder 1 needs to be fixed, the electric push rod 44 is operated, and the electric push rod 44 drives the clamping block 45 to be inserted into the clamping slot 42 at the corresponding position, thereby clamping the connecting piece 41 and fixing the position of the hydraulic cylinder 1, thereby achieving the effect of rotation or fixation, and flexibly adjusting the direction of the hydraulic cylinder 1 when it is fixed.

[0039] The fixing ear 2 is connected to the fixing seat 3 through the fixing component 5. When the hydraulic cylinder 1 rotates, the connecting piece 41 is driven to rotate synchronously. When the hydraulic cylinder 1 needs to be fixed, the electric push rod 44 is operated, and the electric push rod 44 drives the clamping block 45 to be inserted into the clamping slot 42 at the corresponding position, thereby clamping the connecting piece 41 and fixing the position of the hydraulic cylinder 1, thereby achieving the effect of rotation or fixing, and flexibly adjusting the direction of the hydraulic cylinder 1 when fixed.
