[0013] The following will be combined with the accompanying 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.

[0014] See also Figures 1-4 The utility model provides a technical solution: an eccentric door lock adapted for a narrow door frame, one side of the connecting shaft 11 passes through the interior of the second groove 5 and is fixedly connected to one end of the screw 10, and the screw 10 is driven to rotate by the connecting shaft 11.

[0015] A lock hole 13 is fixedly installed at the bottom center of the front surface of the door lock body 1.

[0016] There are nine balls 9 arranged at the top and bottom respectively. The bottom and top of the balls 9 arranged above and below contact the top and bottom of the first handle 2 respectively, which can support the second handle 3 during movement.

[0017] An internal thread groove is provided at the center of the fixing block 7, through which the fixing block 7 is threadedly connected to the surface of the screw rod 10. When the screw rod 10 rotates, the fixing block 7 can drive the second handle 3 to move along the surface of the screw rod 10.

[0018] The adjusting knob 12 is cylindrical in structure, and the surface of the adjusting knob 12 is provided with anti-slip grooves to facilitate the rotation of the adjusting knob 12 .

[0019] After the eccentric door lock is installed, if the door frame is narrow and affects the normal rotation of the handle, the connecting shaft 11 drives the screw 10 to rotate by turning the adjusting knob 12. Since the screw 10 is threadedly connected to the threaded groove opened inside the fixing block 7, the fixing block 7 is fixedly connected to the inner wall of the second handle 3, so that the fixing block 7 drives the second handle 3 to move along the surface of the screw 10 until the second handle 3 moves to a suitable length, which is convenient to operate.

[0020] To sum up: the eccentric door lock adapted for narrow door frames cooperates with each other through the first handle 2, the second handle 3, the fixed block 7, the ball 9, the screw 10, the connecting shaft 11 and the adjusting knob 12. During use, the screw 10 can be rotated by turning the adjusting knob 12, and the screw 10 causes the fixed block 7 to drive the second handle 3 to move, thereby adjusting the handle length of the eccentric door lock to avoid the handle being too long when the door frame is narrow and affecting normal rotation, thereby improving the adaptability of the eccentric door lock, facilitating use, and meeting the user's needs.
