DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] An extremely narrow gear transmission lock box comprises a lock box 1, a base plate 2, a spur gear bar 3, a rotating gear shaft 4 and a decorative auxiliary part 5. A transmission column 6 is provided at one end of the spur gear bar 3, and a rack 7 is provided at the other end. The spur gear bar 3 has two, and the rack 7 ends of the two spur gear bars 3 are close to each other to form a gear installation cavity 8. The rotating gear shaft 4 is arranged in the gear installation cavity 8 and meshes with the racks 7 of the two spur gear bars 3 at the same time. The rack 7 ends of the two spur gear bars 3 are slidably arranged on the decorative auxiliary part 5 with center symmetry. The decorative auxiliary part 5 is clamped in the lock box 1. Bolt holes 9 for installing fixing bolts 10 are provided on the lock box 1, the auxiliary decorative part and the base plate 2. The fixing bolts 10 fix the lock box 1, the auxiliary decorative part and the base plate 2 through the bolt holes 9.

[0023] Specifically, the decorative auxiliary part 5 has two strips, one end of the decorative auxiliary part 5 is provided with a buckle head 11, and the other end is provided with an arc-shaped contact surface 12. When the two decorative auxiliary parts 5 are installed relative to each other, the arc-shaped contact surfaces 12 of the two decorative auxiliary parts 5 are close to each other to form an axis path 13 for the rotating shaft of the rotating gear shaft 4 to pass through, so that the rotating shaft of the rotating gear shaft 4 can smoothly pass through the decorative auxiliary part 5. At the same time, the decorative auxiliary part 5 also provides support and stability for the rotating shaft. A transmission groove 14 is opened in the middle of the decorative auxiliary part 5, and the transmission column 6 is slidably installed in the transmission groove 14 on the decorative auxiliary part 5. A groove 15 is provided on one side of the buckle head 11. When the spur gear bar 3 is driven by the rotating gear shaft 4 to move, the transmission column 6 will slide along the transmission groove 14, thereby driving the decorative auxiliary part 5 to perform corresponding linear motion.

[0024] Specifically, both ends of the bottom plate 2 are provided with strip holes 16, and both ends of the bottom plate 2 surface are provided with protrusions 17, and the protrusions 17 are engaged in the grooves 15 provided at one end of the decorative auxiliary part 5. When the protrusions 17 are engaged in the grooves 15, a locking relationship is formed between the decorative auxiliary part 5 and the bottom plate 2, ensuring the relative position between the two is stable, and preventing the lock box from loosening or misaligning during use. The bottom plate 2 is provided with an axial hole 18 for installing the rotating gear shaft 4 at the rotating shaft corresponding to the rotating gear shaft 4. The rotating gear shaft 4 is installed on the bottom plate 2 through the cooperation and rotation of the rotating shaft and the axial hole 18, so that the rotating gear shaft 4 can rotate freely on the bottom plate 2 without being interfered by other components. When external force acts on the rotating gear shaft 4, it can rotate smoothly, thereby driving the spur gear bar 3 to perform linear motion.

[0025] Specifically, the width of the rack 7 end of the spur gear bar 3 is less than half the width of the connecting end of the transmission column 6. The connecting end of the transmission column 6 of the spur gear bar 3 abuts against the sunken part 22 of the end of the decorative auxiliary part 5, ensuring that the spur gear bar 3 can remain smooth and stable during movement.

[0026] Specifically, vertical baffles 19 are provided on both sides of the lock box 1 .

[0027] Specifically, the shape of the side of the buckle head 11 is adapted to the shape of the vertical baffles 19 on both sides of the lock box 1 , and a buckle head groove 20 is formed at the bottom of the buckle head 11 .

[0028] Specifically, a square recessed keyway 21 is provided in the middle of the rotating gear shaft 4 for installing a key to connect the rotating gear shaft with other transmission or driving components to ensure the stability and reliability of the transmission.

[0029] The working principle of this embodiment is as follows: When used specifically,

[0030] When it is necessary to lock the doors and windows, the rotating gear shaft 4 is driven to rotate through the square recessed keyway rotation operation. Since the rotating gear shaft 4 is meshed with the rack 7 of the spur gear bar 3 at the same time, the rotation of the rotating gear shaft 4 will drive the spur gear bar 3 to move along its length direction. The movement of the spur gear bar 3 is transmitted to the decorative auxiliary component 5 through the transmission column 6. Since the decorative auxiliary component 5 is fixed on the lock box 1 and the base plate 2, this movement will be converted into a locking force for the doors and windows. The lock box 1, the decorative auxiliary component 5 and the base plate 2 are fixedly connected by fixing bolts 10 to ensure the stability of the locking mechanism. When unlocking, the rotating gear shaft 4 is rotated in the opposite direction, and the spur gear bar 3 and the transmission column 6 move in the opposite direction to release the locking force on the doors and windows.

[0031] The remaining parts not described in this utility model are existing or known technologies.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
