[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 7 A reverse locking positioning module for a rear lock body comprises a panel 10 and a reverse locking knob 20 rotatably arranged on the panel 10, a plurality of positioning grooves 120 are arranged in a circular array along the rotation axis of the reverse locking knob 20 on the wall surface of the panel 10 facing the reverse locking knob 20, a positioning piece 30 is arranged between the reverse locking knob 20 and the panel 10, the positioning piece 30 is connected to the reverse locking knob 20, a plurality of elastic parts 310 are arranged in a circular array along the rotation axis of the reverse locking knob 20 on the positioning piece 30, a positioning part 320 which can be embedded in the positioning groove 120 is arranged on the elastic part 310, and the positioning piece 30, the elastic part 310 and the positioning part 320 are an integrated structure.

[0024] The utility model optimizes the number of components and reduces the number of assembled parts by integrating the elastic part and the positioning part on the positioning sheet, thereby effectively improving the assembly efficiency.

[0025] When the anti-locking knob 20 rotates, it drives the positioning piece 30 to rotate synchronously. During the rotation of the two, when the positioning portion 320 corresponds to the positioning groove 120, the positioning portion 320 is embedded in the positioning groove 120. When the positioning portion 320 is located in the positioning groove 120, the rotation of the anti-locking knob 20 drives the positioning piece 30 to rotate synchronously. At this time, the elastic portion 310 will be deformed, so that the positioning portion 320 is separated from the positioning groove 120.

[0026] Furthermore, the elastic part 310 is an integrally stamped spring sheet, which is stamped on the positioning sheet 30 by a stamping process. A stamped deformation groove 311 is provided around the elastic part 310 .

The bolt 50 is used to restrict the movement of the positioning piece 30 toward one side of the panel 10 and to limit the position of the positioning piece 30 to prevent the positioning piece 30 from being separated from the mounting groove 210.

[0033] In the present invention, under the action of the elastic member 40 and the elastic portion 310 , when the anti-locking knob 20 is rotated by an external force, the positioning portion 320 can be better disengaged from the positioning groove 120 .

[0034] See also Figure 5 A threaded hole 220 is provided in the guide groove 230 , and the bolt 50 is threadedly connected to the threaded hole 220 .
