[0080] The designer can set the dialing part to various structural forms according to actual needs, such as arranging multiple protrusions on one side of the limiting assembly 130, or arranging a continuous protrusion in the form of teeth, or arranging a dial rod structure, which can all assist the user to drive the limiting assembly 130 to rotate.

[0081] Figure 7 The first or second lock bolt of the screen door lock is shown in the structure diagram. Figure 7 As shown, in an embodiment of the present application, the sliding dial seat 110 is provided with a lock rod, which is arranged to extend along the sliding direction of the sliding dial seat 110.

[0082] The limiting assembly 130 is rotatably arranged on the frame 200, and the limiting assembly 130 is provided with a through channel 132, and when the limiting assembly 130 is in the first rotating position, the through channel 132 is suitable for accommodating at least part of the lock rod.

[0083] When the limiting assembly 130 is in the first rotating position through the rotating movement, in the process of the sliding dial seat 110 sliding on the frame 200, the lock rod can extend into the through channel 132, so as to drive the lock bolt assembly 120 to move and make the screen door and the window frame in a separable state, that is, in an unlocked state, when the limiting assembly 130 is in other positions, the screen door and the window frame are in a locked state and cannot be opened.

[0084] For preventing children from operating by mistake, only one rotation position of the limiting assembly 130 allows the sliding knob 110 to drive the bolt assembly 120 to move and open the screen window during the rotation of the limiting assembly 130, and the limiting assembly 130 is in other positions, which can prevent the sliding knob 110 from sliding along the frame 200, so that the probability of opening the screen window by mistake of children is greatly reduced.

[0085] In some embodiments of the utility model, the frame 200 is provided with a cavity 210, the bolt assembly 120 comprises a first bolt piece 121 and a second bolt piece 122, and the first bolt piece 121 and the second bolt piece 122 are arranged in the cavity 210; wherein the first bolt piece is connected with the first sliding knob 111, and the second bolt piece is connected with the second sliding knob 113.

[0086] The screen window lock 100 in the embodiment sets the first bolt piece 121 and the second bolt piece 122 in the cavity 210 of the frame 200, which is equivalent to hiding part of the components of the screen window lock 100, the components of the screen window lock 100 exposed outside the frame 200 are less, and the whole is more beautiful.

[0087] Figure 3 It is a perspective structural schematic view of a view angle of the screen window lock of the utility model; Figure 4 It is a perspective structural schematic view of another view angle of the screen window lock of the utility model; combined Figure 3 And Figure 4 The screen window lock 100 provided by the utility model, the sliding knob 110 can drive the bolt assembly 120 to slide along the frame 200, when the bolt assembly 120 is connected to the window frame, the screen window is locked to the window frame, by setting the limiting assembly 130, the sliding knob 110 can be prevented from sliding in the opposite direction, so that the screen window and the window frame are in an openable state, and by the identification part 131 on the limiting assembly 130, the specific position of the limiting assembly 130 can be judged, whether the screen window is in a locked state can be finally known, especially when a plurality of identification parts 131 are arranged on the limiting assembly 130, children are difficult to judge the specific position of the limiting assembly 130 by observing the plurality of identification parts 131, the probability of opening the screen window by mistake is greatly reduced, thereby playing a protective role on children.

[0088] In some embodiments of the utility model, a plurality of identification parts 131 are arranged on the limiting assembly 130, and only one identification part 131 is used to identify that the limiting assembly 130 is located at the first rotation position.

[0089] The screen window lock 100 in the embodiment sets a plurality of identification parts 131, but the plurality of identification parts 131 can hinder children from opening the screen window lock 100, because in the plurality of identification parts 131, only one identification part 131 enables a user to identify that the limiting assembly 130 is at the first rotation position.

[0090] In the utility model, the terms such as "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "side", "bottom" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only the relationship words determined for the convenience of narrating the structural relationship of various components or elements of the utility model, and cannot be understood as the limitation of the utility model.
