Description

Technical Field

[0001] The utility model relates to the technical field of padlocks, and in particular to a padlock mechanism. Background Art

[0002] The padlock mechanism is a locking device, generally used on double doors, which uses a hook to lock the two doors together to lock the doors.

[0003] The authorized patent for a padlock mechanism and a logistics vehicle, with an authorization announcement date of June 23, 2023 and an authorization announcement number of CN219241623U, proposes a feasible padlock mechanism that can be operated with one hand and is easy to use. However, the door lock hook (i.e., the hook claw 18) of this padlock mechanism only has a locking member that can maintain its horizontal position to prevent it from sliding out of position. However, the hook design is simple. If there is an angle deviation, the hook cannot ensure the hooking and locking effect on the double door, resulting in a lack of guaranteed locking effect. When used for a long time and the hook becomes loose, the locking effect on the door will become increasingly poor, affecting the locking effect.

[0004] Therefore, in view of the shortcomings of the above solution in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of striving for excellence, and with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, a padlock mechanism is provided to solve the problems of poor locking effect and lack of locking guarantee of the current locking mechanism.

[0028] like Figures 1 to 4As shown, the padlock mechanism includes a U-shaped lock frame 5 and a U-shaped connector 3. Both sides of the U-shaped lock frame 5 are covered with cover plates. The U-shaped connector 3 is arranged inside the U-shaped lock frame 5. The U-shaped lock frame 5 includes a middle frame plate 11 located in the middle and side frame plates 2 connected to both sides of the middle frame plate 11. The middle frame plate 11 is penetrated by a push rod 19. The inner side of the push rod 19 is connected to the U-shaped connector 3. The outer side of the push rod 19 is connected to the push rod 19 transmission mechanism 16, including a hook rear sliding column 9, The front sliding column 8 of the hook is connected to the door lock hook 6, and the end of the U-shaped connecting member 3 is connected to the rear sliding column 9 of the hook. A strip slide groove 4 is provided on the side frame plate 2. The two ends of the rear sliding column 9 and the front sliding column 8 of the hook are respectively slidably connected to the strip slide groove 4 on both sides. The door lock hook 6 is rotatably connected to the front sliding column 8 of the hook. The door lock hook 6 includes an external hook end 13 and an internal plate end 14. A hook torsion spring 10 is provided on the rear sliding column 9. The hook torsion spring 10 is used to apply force to the internal plate end 14.

[0029] To clearly show the structure of this solution, Figure 1 and Figure 2 Hide the cover and show the internal structure. Figure 4 The external connecting plate 20 is hidden in order to show the internal structure more clearly.

[0030] The push rod 19 transmission mechanism 16 includes a limit block fixed on the outside of the limit block U-shaped lock frame 5, and the limit block is used to limit the push rod 19. The two sides of the limit block are rotatably connected with an external connecting plate 20. The outer end of the push rod 19 is hinged with two internal connecting plates 22 using a first connecting shaft 21. The internal connecting plate 22 is rotatably connected to the external connecting plate 20 on the same side using a second connecting shaft 18, and the internal connecting plate 22 is connected to a handle connector 23.

[0031] The door lock handle 12 is rotatably connected to the handle connector 23 .

[0032] The door lock handle 12 is rotatable for easy storage.

[0033] The two sides of the handle connector 23 can be designed to have one side open and the other side closed, and a torsion spring is provided to facilitate the reset of the door lock handle 12.

[0037] The utility model is to use the push rod 19 transmission mechanism 16 to provide power, specifically: Figure 2 and Figure 4, rotate the handle connector 23 and the handle from a horizontal position to a vertical position. During this process, the first connecting shaft 21 will give the push rod 19 a rightward force, causing it to move right, and the external hook end 13 will move right synchronously to achieve locking of the door body. In this process, the hook torsion spring 10 cooperates with the cover plate to generate an outward thrust (i.e. Figure 2 Since the door lock hook 6 and the rear sliding post 9 are rotatably connected, it is equivalent to giving the external hook end 13 inward (ie Figure 1 The thrust from the center to the right can achieve a better locking effect.

[0038] The beneficial effects of this utility model are:

[0039] When the padlock mechanism is used to lock a double door, it mainly hooks the door body to achieve locking when the double door is closed. Therefore, whether the door body can be firmly hooked open is the key to locking.

[0040] The door lock hook of this practical hook mechanism will automatically tighten under the action of the hook torsion spring. Even if there is an angle deviation, it can ensure that the hook is firmly hooked on the door body, playing a good hooking role. Therefore, the locking effect is good and guaranteed, and the locking effect will not be reduced due to the application time. It solves the problem of poor locking effect and lack of locking guarantee of the current locking mechanism.
