Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1, the padlock of the present invention includes two padlock units 1, and the two padlock units 1 are used to lock a case 2 together. The box body 2 has a first opening and closing side 21 and a second opening and closing side 22, and each of the latch units 1 is arranged along the length direction of the edge of the first opening and closing side 21.

Each of the latch units 1 includes a fixed housing 11 and a swing housing 12, see fig. 3. Each fixed housing 11 and each swing housing 12 are curved, and each fixed housing 11 and each swing housing 12 are disposed at corners of the box body 2. The fixed housing 11 is fixed to the edge of the first opening/closing side 21, and one end of the swing housing 12 is hinged to the fixed housing 11.

All be equipped with hasp 3 in each fixed casing 11, hasp 3 slidable connects in fixed casing 11. The second opening/closing side 22 is provided with a latch hook 4 (see fig. 2), and the latch hook 4 can be hooked by the latch 3 to keep the box body 2 closed. The swing shell 12 is provided with a circular pin hole 121, the latch 3 is provided with a connection long hole 31, and a transmission pin (not shown) is arranged in the circular pin hole 121 and the connection long hole 31 in a penetrating manner, so that the swing shell 12 can drive the latch 3 to slide to the latch 3 without hooking the latch hook 4, and the box body 2 can be opened.

The free end of each swing case 12 is slidably connected with an opening slider 6. And a support rod 7 and a lock cylinder component are arranged in each fixed shell 11. The middle part of the supporting rod 7 is hinged with the fixed shell 11. The lock cylinder assembly comprises a lock cylinder 81 and a rotating ring 82, the rotating ring 82 is sleeved at the tail end of the lock cylinder 81, the rotating ring 82 is provided with a convex part 821, and the convex part 821 can stir the head end of the support rod 7 so as to enable the support rod 7 to swing. The middle sliding block 9 is arranged in each fixed shell 11, and the middle sliding block 9 is connected with the fixed shell 11 in a sliding mode. In the locked state (see fig. 4), the projection 821 of the rotating ring 82 is held against the head end of the support lever 7 so that the support lever 7 cannot swing (about the C-axis in fig. 4). At this time, the intermediate slider 9 is pressed against the rear end of the support rod 7 and cannot slide, so that the opening slider 6 remains hooked to the fixed housing 11, so that the swing housing 12 cannot swing. Since the swing housing 12 cannot swing, the swing housing 12 cannot drive the latch 3 to slide without hooking the latch hook 4, so that the box body 2 remains closed.

The unlocking process of the padlock of the invention is as follows:

referring to fig. 5 and 6, a key (not shown) is inserted into the key cylinder 81, and then the key cylinder 81 is rotated so that the projection 821 does not abut against the head end of the support rod 7 (as shown in fig. 5), and the support rod 7 is swung by the spring until the tail end of the support rod 7 does not abut against the intermediate slider 9, so that the intermediate slider 9 can slide relative to the fixed housing 11 without abutting against the opening slider 6. At this time, the opening slider 6 is pushed so that the opening slider 6 does not hook the fixed housing 11, so that the swing housing 12 can swing. Then, referring to fig. 6, when the swing housing 12 swings to the left by a certain angle (around the axis a in fig. 6), the swing housing 12 drives the latch 3 to slide to the left through the driving pin (the driving pin sequentially passes through the circular pin hole 121 and the connecting long hole 31, the driving pin is not shown), so that the latch 3 slides to not hook the latch hook 4, and at this time, the box body 2 can be opened.

During the locking process, the operator can grasp one swing housing 12 with both hands, and then simultaneously swing both swing housings 12 from outside to inside until both swing housings 12 swing to the free ends thereof to respectively buckle two opposite side surfaces of the first opening/closing side 21. In the above process, the free ends of the two swing shells 12 swing to two opposite side surfaces close to the first opening and closing side 21 at the same time, and at this time, the operator can lock the free ends of the swing shells 12 at one time by pressing the free ends of the two side surfaces with two hands at the same time in the normal direction. At the moment of pressing the free end of the swing shell 12, the directions of the forces generated by the two hands are both from outside to inside, the directions of the two forces are opposite, the resultant force of the two forces is almost zero, the box body cannot move due to stress, the box body can be kept stable, and therefore one hand does not need to be vacated to press the box body in the locking process. Therefore, an operator only needs to lock the two buckling units simultaneously by two hands at one time, and the locking process is convenient.

Specifically, each of the fixed housings 11 and each of the swing housings 12 are curved, and each of the fixed housings 11 and each of the swing housings 12 are disposed at corners of the box body 2. The swing case 12 is curved such that a free end of the swing case 12 is located at a side of the cabinet 2 and a hinged end of the swing case 12 is close to a front surface of the cabinet 2 (see fig. 1 to 3). The free end of the swing shell 12 is positioned on the side surface of the box body 2, so that an operator can simultaneously press the free end of the swing shell towards the normal direction of the two side surfaces by using two hands, and one-time locking can be realized; the hinged end of the swing case 12 is close to the front of the case 2 so that the latch hook 4 can still be disposed inside the front of the case 2, i.e., the locking positions of the first opening and closing side 21 and the second opening and closing side 22 are located at the front of the case 2, thereby ensuring the locking strength.

The above disclosure is only for the preferred embodiment of the present invention, and it should be understood that the present invention is not limited thereto, and the invention is not limited to the above disclosure.
