[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 , this utility model provides two technical solutions:

[0027] Embodiment 1, double door additional lock, comprising:

[0028] The latch 1 has a sliding groove 2 formed at the top and bottom of the surface of the latch 1, a groove 5 formed at the top of the surface of the latch 1, and a plurality of receiving slots provided on the surface of the latch 1, which can be adapted to the steel ball 38. The shape of the latch 1 is U-shaped;

[0029] A locking assembly 3 is movably connected to the surface of the latch 1 and is used to adjust the locking on the surface of the latch 1;

[0030] Auxiliary slot 4, auxiliary slot 4 is located on the left side of the surface of the latch 1. By utilizing the setting of the locking component 3, the pin locking method is designed as a component, which cooperates with the latch 1 and the receiving slot on its surface to increase the locking range. The door can be locked or unlocked by turning the dial button 34, and the lock head 36 is added to quickly lock the dial button 34. It is die-casted with metal material. A rectangular notch is designed on one side of the U-shaped latch for better access. The upper and lower sides of the back are thickened to increase the strength of the product, solving the problems of existing double-door additional locks that cannot be adjusted and have a small locking range.

[0031] The second embodiment differs from the first embodiment mainly in that: the double-door additional lock has a locking assembly 3 comprising a lock housing 31 movably connected to the surface of the latch 1; a lock cover 32 is fixedly connected to one side of the surface of the lock housing 31; a slider 33 is movably connected to the inner wall of the lock cover 32; a dial button 34 is movably connected to the surface of the lock cover 32; one side of the dial button 34 passes through the lock cover 32 and extends to the inner wall of the lock cover 32; one side of the dial button 34 is fixedly connected to a cross-recessed pan head cap screw 35; the surface of the cross-recessed pan head cap screw 35 is provided with anti-slip textures. A lock head 36 is movably connected to the top of the lock cover 32, and the surface of the lock head 36 is chrome-plated. A steel ball spring 37 is fixedly connected to one side of the inner wall of the lock shell 31, and a steel ball 38 is movably connected to one side of the steel ball spring 37. A cross-slot countersunk screw 39 is passed through the surface of the lock shell 31, and the surface of the cross-slot countersunk screw 39 is provided with anti-slip textures. By utilizing the setting of the groove 5, grooves are provided on the upper and lower sides to facilitate alignment and locking in the field of vision. Through the setting of the sliding groove 2, the lock shell 31 can slide smoothly on its surface, and it is not easy to be misplaced during the sliding process.

[0032] A protruding lock pin is provided on the lock head 36. By pressing the lock head 36 to lock the pin, the dial button 34 can be quickly slid to lock. A rectangular notch auxiliary groove 4 is provided on one side of the lock latch 1, and grooves 5 are provided on the upper and lower sides. The lock is performed by sliding the dial button 34 up and down. When the dial button 34 slides up and down, the locked and unlocked displays can be displayed or covered, thereby prompting the user. There is an indicator scale on the lock latch 1 for the user to refer to the position when locking, so that the locking structure can be accurately slid to lock. The product locking range is expanded, and it is not only suitable for locking the ball lock device above, but also for locking the double-handle lock and the double-door device with double large handles.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] When working, hold the auxiliary slot 4 and slide the lock shell 31 in the sliding slot 2 on the surface of the latch 1. When the lock shell 31 moves to a suitable position on the surface of the latch 1, you can quickly press the lock head 36 to quickly fix the lock shell 31. At this time, the steel ball spring 37 pushes the steel ball 38 to embed and connect with the positioning slot. When separating, after the lock head 36 is locked, you need to use a key to unlock it before you can dial the dial button 34. Just push the dial button 34 and the lock head 36 will move up. At this time, move the lock shell 31 on the surface of the latch 1 to remove it and restore it.
