[0002] The locking mechanism is a position control device that locks and unlocks movable parts through tapered positioning pins, ultimately achieving precise locking and unlocking of the angle and position of the mechanical mechanism.

[0003] As the demand for existing mechanical systems continues to expand, the requirements for positional precision control of moving parts continue to increase, and locking mechanisms are becoming increasingly widespread. Locking pin-type locking mechanisms are used in various folding mechanism systems to improve the stability of the folding mechanism system during its working phase. Folding mechanism systems are typically unlocked when not in operation. During testing of folding mechanism systems, multiple locking and unlocking operations are required. Locking occurs when the mechanism automatically pops out, while unlocking requires the use of external tools. Existing unlocking tools are single-sided prying tools, which can easily cause misalignment of the locking mechanism. Therefore, research and application of unlocking technologies for locking mechanisms are imperative. Summary of the Invention

[0023] It should be noted that, in this embodiment, the terms "front", "back", "upper", "lower", etc. are used to simplify the description or to describe according to the accompanying drawings, wherein "front" and "back" correspond to Figure 1 The terms “left” and “right” should be understood by those skilled in the art in accordance with the technical solution of this embodiment.

[0024] The following is combined with Figure 1-5 The present invention is further described in detail: an unlocking device for a locking mechanism is an unlocking tool designed for the locks of certain types of products. It is a device used to complete positioning and unlocking during the working stage. It aims to reduce labor intensity, effectively improve production efficiency while accurately unlocking, and ensure product quality; it uses hinges and thread adjustments, precise positioning, and lever assistance to achieve low-intensity, high-efficiency, and standardized unlocking effects.

[0025] The unlocking mechanism uses a mechanical connection transmission method, which includes connecting the reference base 3 and the handle 1 via a connecting bolt 4, and then connecting the handle 1 to the unlocking U-shaped rod 2 via an adapter shaft 6, together forming the unlocking device. The specific structure is as follows: The unlocking device of the locking mechanism comprises three basic structures: the reference base 3, the handle 1, and the unlocking U-shaped rod 2;

[0026] The main structure of the reference base 3 is a cube, with a positioning column protruding from its front end, which has a positioning and guiding function. The positioning column is provided with an avoidance groove for avoiding the locking mechanism, and the protruding portion of the rear end surface is a connecting boss for the handle 1. One end of the handle 1 is connected to the connecting boss by a connecting bolt 4. The upper end surfaces of the connecting boss and the avoidance groove are both flush with the upper end surface of the reference base 3, and the center lines of the upper end surfaces of the two are on the same horizontal line.

[0027] The handle 1 is a special-shaped long handle structure, similar to an inverted Z shape, with two holes opened on it for connecting the various components; one hole is located at the end of the handle 1, which is an oppositely arranged ear piece, and the hole is set on the ear piece and is a threaded hole, which is connected to the connecting boss through a connecting bolt 4 adapted thereto;

[0028] As a preferred embodiment of this embodiment, the reference base 3 and the handle 1 are connected by a connecting bolt 4, a spring washer 10, a fastening nut 11, and a washer 12. That is, the connecting bolt 4 passes through the ear piece, the connecting boss, the ear piece, the washer 12, the spring washer 10, and the fastening nut 11 in sequence;

[0029] The unlocking U-shaped rod 2 is U-shaped, with a threaded end for connection and fastening, and a C-shaped notch at the bottom for unlocking and positioning. The handle 1 is connected to the unlocking U-shaped rod 2 via an adapter shaft 6. The unlocking U-shaped rod 2 and the adapter shaft 6 are adjusted and fastened in place by limit nuts I5, II7, III8, and IV9.

[0030] The adapter shaft 6 is a cylinder, and through holes are provided on both sides of the adapter shaft for the threaded section of the unlocking U-shaped rod 2 to pass through, and the adapter shaft is restricted on the handle by a matching limiting nut.

[0031] Instructions for use: Insert the locking mechanism into the reference base 3 through the positioning column and avoidance groove on the front end of the reference base 3. After the positioning adjustment is completed, use the handle 1 to unlock the U-shaped rod 2 through the connecting bolt 4 and the rotating shaft 6. Buckle the C-shaped notch at the bottom of the unlocking U-shaped rod 2 into the toggle pin of the locking mechanism. Turn the end of the handle 1 to move the toggle pin of the locking mechanism along the direction of the reference base 3. Then, the toggle pin pulls the tapered pin of the locking mechanism out of the positioning hole, thereby unlocking the locking mechanism in the working stage. The present invention has strong scalability, high movement stability during the product unlocking process, and simple operation. It can be replaced and adjusted in combination with the product's external structure, is suitable for unlocking different types of locking mechanisms, and can meet the unlocking needs of multiple types of locking mechanisms.
