A first half opening that can form the same storage space (A) is respectively formed. The first half of the slot 15 and the second half of the slot 25 are used to receive and assemble the segmented lock assembly 30, wherein the second and half of the slots (25, 15) respectively have a main shaft rod 31 for pivoting one end of the segmented lock assembly 30 and a lock head 32 for selectively buckling the other end of the segmented lock assembly 30. The main embodiment of the invention is to pivot the segmented lock assembly 30 with the main shaft rod 31 arranged in the second half of the slot 25, and to arrange the lock head 32 on the wall surface of the first half of the slot 15 for the segmented lock assembly 30, wherein the free end of the lock head 32 has an oblique cone buckle portion 33, and the oblique cone buckle portion 33 can be used to guide the segmented lock assembly 30 to automatically buckle the lock head 32 (such as Fig.10As shown), a locking rod 35 is disposed transversely in the first half-open slot 15 adjacent to the second hinge 20 for selectively locking the segmented lock assembly 30;

[0028] The segmented lock assembly 30 has a pressure plate 40 and a locking member 50 that can be coaxially pivoted on the main shaft rod 31, wherein the pressure plate 40 is a U-shaped cross-section frame, and a first pivot hole 41 for the main shaft rod 31 to pass through is formed on both sides of the bottom end of the pressure plate 40, and the other end of the pressure plate 40 different from the first pivot hole 41 has a slide hole 42 corresponding to the aforementioned lock head 32, and the slide hole 42 can be slidably provided with a limit slide buckle 45, and the limit slide buckle 45 has a push portion 450 that slides on the outer surface of the pressure plate 40, which is convenient for the user to push The limit slide buckle 45 is moved, and a lock piece 47 corresponding to the lock head 32 is locked on the limit slide buckle 45, so that the limit slide buckle 45 can be locked on the lock head 32 when sliding forward and backward. A reset elastic member 46 is provided between the limit slide buckle 45 and the pressure plate member 40, so that the limit slide buckle 45 can generate a pre-force for automatic reset backward, so that the limit slide buckle 45 can automatically reset backward after sliding forward. The bottom end of the pressure plate member 40 has a stop edge 49, so that the pressure plate member 40 can use the stop edge 49 to generate a limiting effect relative to the locking member 50;

[0029] Furthermore, the locking member 50 is a frame that can be accommodated in the pressure plate member 40, and the bottom ends of the locking member 50 are formed with a second pivot hole 51 for the main shaft rod 31 of the second hinge 20 to pass through. The top of the locking member 50 has a lock seat 52, and when the locking member 50 is pivoted on the main shaft rod 31 of the second hinge 20, the height of the lock seat 52 exceeds the lock rod 35 of the first hinge 10, and the lock seat 52 has a penetrating adjustment screw hole 53, and a lock post 54 convex to the bottom surface of the lock seat 52 can be locked in the adjustment screw hole 53, so that the locking member 50 can use the lock post 54 on the lock seat 52 to lock and limit relative to the lock rod 35. Furthermore, the locking member 50 is locked in the A reset torque spring 55 is sleeved on the main shaft rod 31, and the reset torque spring 55 has a first support leg 551 and a second support leg 552, wherein the first support leg 551 of the reset torque spring 55 is supported on the inner wall surface of the second half-open groove 25 of the second hinge 20, and the second support leg 552 is inserted into a support hole 520 formed in the lock seat 52, so that the locking member 50 can generate a reset pre-force to automatically close the lock rod 35, and the bottom end of the locking member 50 has at least one stop block 59 corresponding to the stop edge 49 of the aforementioned pressure plate member 40, so that the pressure plate member 40 can use the stop edge 49 to limit the stop block 59 of the locking member 50 (such as Figure 6 as shown) and pressure (as shown Figure 7 Thus, a folder docking lock structure with double insurance and automatic locking function is formed.

[0030] Regarding the actual operation of the docking lock structure of the folder of this invention, Figure 4 As shown, when the first and second hinges (10, 20) are normally connected and locked into a single body 100 by using the segmented lock assembly 30, the first and second hinges (10, 20) are connected to each other with the pivot rod 22 of the first and second pivot parts (11, 21) as the axis, and the segmented lock assembly 30 pivotally mounted on the second hinge 20 by using the main shaft rod 31 is received in the first and second half-opening grooves (15, 25) of the first and second hinges (10, 20). ), and at the same time, the lock post 54 on the locking member 50 of the segmented lock assembly 30 is locked on the lock rod 35 of the first half-open groove 15, and the limit slide buckle 45 of the pressure plate member 40 is locked on the lock head 32 in the first half-open groove 15, so that the first and second hinges (10, 20) produce a locking and limiting effect, and at the same time, the pressure plate member 40 of the segmented lock assembly 30 can be prevented from slipping off arbitrarily, thereby forming a double insurance effect.

[0031] When folding is required, Figure 5 , Figure 6 and Figure 7 As shown, the limit slider 45 on the pressure plate 40 of the segmented lock assembly 30 is pushed forward through the push portion 450, so that the limit slider 45 can compress the reset elastic member 46 to generate a pre-force for reset backwards, and at the same time, the lock plate 47 of the limit slider 45 can be separated from the lock head 32 in the first half-open groove 15 of the first hinge 10 (as shown in FIG. Figure 5 Then, the pressing plate 40 is turned outward (as shown in FIG. Figure 6 As shown in FIG. 1 , the pressing plate 40 can use the stop edge 49 at the bottom edge to limit the stop block 59 of the locking member 50. If it is a false action, when the user does not continue to press the pressing plate 40, the lock post 54 of the locking member 50 will not fall out of the lock rod 35, so as to avoid the situation of improper unlocking. When the user really needs to unlock, as shown in FIG. Figure 7 As shown, the pressing plate 40 is continuously pressed outwardly, so that the pressing plate 40 is pressed against the stop block 59 of the locking member 50 with the stop edge 49, and the locking member 50 is pushed, so that the lock post 54 on the lock seat 52 of the locking member 50 can be separated from the lock rod 35, and the locking member 50 can simultaneously compress the reset torque elastic member 55 to generate a reset pre-force, so that the first and second hinges (10, 20) can be relatively folded with the pivot rod 22 of the first and second pivot parts (11, 21) as the axis (as shown in FIG. Figure 8 As shown), it can produce the effect of easy unlocking and quick completion of the folding operation.

[0032] When the first and second hinges (10, 20) need to be reconnected, Fig. 9 and Fig.10 As shown, the first and second hinges (10, 20) are pivotally connected and joined with the pivot rods 22 of the first and second pivot parts (11, 21) as the axis, and then the locking member 50 of the segmented lock assembly 30 is reset by the reset torque spring 55 on the main shaft rod 31, so that the lock post 54 on the lock seat 52 of the locking member 50 can be locked on the lock rod 35 due to the pre-force of the reset torque spring 55, thereby producing an automatic locking effect. At the same time, the locking member 50 further uses the stop block 59 at its bottom end to abut against the stop edge 49 of the pressure plate member 40, so that the pressure plate member 40 can be synchronously driven to the position ready for pressing. Finally, the user applies force to press the pressure plate member 40 (as shown in FIG. Fig.10 As shown in FIG. 1 , the locking piece 47 of the limit slide buckle 45 on the pressure plate 40 of the segmented lock assembly 30 is locked on the oblique cone buckle portion 33 of the lock head 32, thereby generating a double insurance effect, which can enhance the convenience of operation and improve the safety of its use.

[0033] Through the above-mentioned design and description, the folder docking lock structure of the present invention utilizes the design of the locking member 50 and the pressure plate member 40 respectively on the segmented lock group 30 pivotally arranged on the second hinge 20, so that the locking member 50 can be locked with the locking rod 35 on the first hinge 10 by the locking column 54 of the lock seat 52 of the locking member 50 and the limiting slide 45 of the pressure plate member 40 is limited to the locking head 32 on the first hinge 10, thereby producing a two-stage safety lock mechanism, which effectively avoids unlocking of the misoperating parts, and utilizes the reset torque spring 55 of the segmented lock group 30 to achieve the automatic locking function, making the folding and closing and docking lock operations more convenient, and at the same time it can have a stronger locking force, which can further improve the structural properties of the docking lock and enhance the safety of its use.
