Description

Technical Field

[0001] This utility model relates to the field of mechanical design technology, and in particular to a fully automatic unlocking device suitable for mechanical locking mechanisms. Background Technology

[0002] A pin-type mechanical locking mechanism is a mechanical device that uses a rigid pin and a pin hole to achieve rapid positioning and locking of components. Its core components include a pin body, a pin hole seat, a spring return mechanism, and a manual / automatic release device.

[0003] With the ever-expanding demands of existing mechanical systems, the requirements for precise position control of moving parts are also constantly increasing, leading to the increasingly widespread application of locking mechanisms. During operation, the pin is embedded in a matching pin hole under spring preload or external power, forming a rigid constraint through geometric interference, effectively resisting shear forces and axial loads. During unlocking, the pin is disengaged from the pin hole by lifting, rotating, or electromagnetic drive, achieving rapid separation. This mechanism features simple structure, strong impact resistance, and high load-bearing capacity, making it particularly suitable for heavy equipment positioning, vehicle trailer connections, and industrial fixture fixing. However, existing unlocking tools are manual mechanical levers, which can easily cause misalignment of the locking mechanism. Therefore, the research and application of automatic unlocking technology for locking mechanisms is imperative. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a fully automatic unlocking device suitable for mechanical locking mechanisms, so as to solve the problems in the background art mentioned above.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A fully automatic unlocking device for a mechanical locking mechanism includes a reducer, a locking mechanism, a control switch, a driver, a push rod, a limit pin, a push plate, a locking component, and a base. The upper part of the base is provided with a locking component for locking and limiting the push plate. The push plate is connected to the push rod, and the push rod is connected to the driver. A limit pin is provided on one side of the base for connecting and securing the base, the push plate, and the locking mechanism. The locking mechanism is fitted onto the bottom of the base. The reducer is located at one lower end of the base, and the control switch is located at the other lower end of the base, connected to the reducer. The reducer is connected to the driver.

[0007] In this invention, the bottom of the base has a cylindrical clearance groove for mounting the locking mechanism.

[0008] In this utility model, the base, the push plate, and the locking mechanism are respectively provided with mounting holes for inserting the limit pin.

[0009] In this invention, the upper part of the base has an opening groove for moving the push plate.

[0010] In this invention, the upper part of the base is provided with threads for connecting with a fastener.

[0011] In this invention, during use, the locking mechanism is first fitted onto the bottom of the base. Then, the limiting pin is inserted into the mounting holes of the base, the push plate, and the locking mechanism to secure them together. The control switch is then pressed to start the process. The power is adjusted and transmitted to the driver via the reducer. The driver pushes the push rod connected to it forward. The push rod pushes the push plate forward. The push plate is connected to the locking mechanism via the limiting pin, causing the locking pin of the locking mechanism to move forward. Finally, the locking pin is pulled out of the locking hole, thus achieving fully automatic unlocking of the locking mechanism.

[0012] Beneficial effects: This utility model achieves a balance between safety and convenience through modular design. The reducer precisely adjusts the power output, the driver responds quickly, and the push rod stably transmits mechanical motion. Combined with the sturdy base, it forms a complete power closed loop with strong expandability. The product exhibits high stability and easy operation during unlocking. Furthermore, it can be replaced and adjusted according to the product's shape and structure, making it suitable for unlocking different models of locking mechanisms and meeting the unlocking needs of various locking mechanisms.
