[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] See also Figure 1-Figure 5A rotary cover type knob hidden structure comprises an indoor lock body 10, wherein the indoor lock body 10 is provided with a cavity 100 with a rear end opening, wherein a reverse locking knob 120 is provided in the cavity 100, wherein the reverse locking knob 120 is rotatably provided on the indoor lock body 10, wherein a cover plate 20 for closing the cavity 100 is provided at the rear side of the cavity 100, wherein the cover plate 20 is rotatably provided on the indoor lock body 10 with a connecting shaft 201 as a rotation axis, and wherein a locking assembly 30 for locking the cover plate 20 is provided on the indoor lock body 10. By providing a locking assembly, the cover plate can be restrained and locked, so as to avoid the problem of opening the cover plate by accidental touch during use, reduce the occurrence of misoperation, and improve safety.

[0019] See also Figure 4 The locking assembly 30 includes a mounting pin seat 310 fixedly mounted in the cavity 100, a locking pin 320 that can move forward and backward relative to the mounting pin seat 310 is provided on the mounting pin seat 310, and an elastic acting member 350 for driving the locking pin 320 to move toward the rear side is provided on the mounting pin seat 310. A locking pin groove 210 for plugging and locking with the locking pin 320 is provided on the front end surface of the cover plate 20, and a lever 330 is provided on the locking pin 320 for driving the locking pin 320 to move toward the front side to disengage it from the locking pin groove 210, and one end of the lever 330 passes through the cavity 100 and extends to the outside of the indoor lock body 10.

[0020] like Figure 4 As shown in the figure, the locking pin 320 is in a locked state, and the locking pin 320 is inserted into the locking pin groove 210. The rotation of the cover plate 20 is restricted by the locking pin 320, so that the cover plate 20 cannot be opened.

[0021] When the user needs to open the cover 20 to operate the anti-locking knob 120, one hand pushes the lever 330, thereby driving the locking pin 320 to move forward to disengage it from the locking pin groove 210. In this state, the cover 20 is no longer constrained by the locking pin 320, and it can be connected to the shaft 201 as the rotation axis to rotate to achieve opening.

[0022] See also Figure 4 A through slot 101 is provided on the lower end surface of the indoor lock body 10 , and one end of the lever 330 passes through the through slot 101 and extends to the outside of the indoor lock body 10 .

[0023] See also Figure 4 The lower end of the shifting rod 330 is connected to a shifting block 340 .

[0024] Furthermore, the lever 330 and the toggle block 340 are fixedly connected by screws.

[0025] See also Figure 5 A connecting shaft 201 is provided on the cover plate 20 , and the connecting shaft 201 is rotatably connected to the indoor lock body 10 .

[0026] See also Figure 5 The indoor lock body 10 is provided with a countersunk hole 130 at a position corresponding to the connecting shaft 201, and a connecting screw 40 is provided in the countersunk hole 130, and the connecting screw 40 is threadedly connected with the connecting shaft 201. The screw head of the connecting screw 40 is embedded in the countersunk hole 130, which not only does not affect the appearance, but also can constrain the front and rear position of the cover plate 20. When the cover plate 20 is assembled, the front end surface of the cover plate 20 is fitted with the rear end surface of the indoor lock body 10, and then the cover plate 20 cannot move forward and backward, left and right, or up and down relative to the indoor lock body 10 through the constraint of the connecting screw 40.

[0027] Furthermore, the connecting shaft 201 can be connected to the indoor lock body 10 by using an existing assembly method.
