For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figures 1 to 10 As shown, the micro-ventilation control device of the present invention comprises a control mechanism 10, a swing arm mechanism 20 and a transmission rod 30, which are used to control the opening and closing states of the micro-ventilation window.

[0050] See also Figures 1 to 7 As shown, the control mechanism 10 includes a control handle 11, a linkage assembly 12 connected to the control handle 11, and a plug-in 13 fixed to one side of the linkage assembly 12; the control handle 11 rotates to drive the linkage assembly 12 to move up and down, thereby driving the plug-in 13 to move up and down. In this embodiment, the plug-in 13 is arranged in a U shape.

[0051] Specifically, the control mechanism 10 further includes a housing 14, which includes a handle seat 141 and a bottom plate 142 that are assembled and connected. The control handle 11 is rotatably connected to one side of the handle seat 141, and the linkage assembly 12 is assembled on the inner side of the housing 14; the bottom plate 142 is provided with a long through hole 143, and the plug-in 13 passes through the through hole 143, and the plug-in 13 slides along the length direction of the through hole 143.

[0052] Specifically, the linkage assembly 12 includes a transmission member 121 that is assembled and connected to the control handle 11 and rotates synchronously, and a movable member 122 that is transmission-connected to the transmission member 121, and the plug-in 13 is fixed on the movable member 122; the outer wall of the transmission member 121 is provided with a transmission tooth 123, and the end of the movable member 122 close to the transmission member 121 is provided with a rack 124, and the transmission tooth 123 is meshed and connected with the rack 124; the end of the transmission member 121 facing the control handle 11 is provided with a plug-in shaft 125, and the cross-sectional shape of the plug-in shaft 125 is rectangular; the end of the control handle 11 facing the transmission member 121 is provided with a slot 111, and the plug-in shaft 125 is engaged in the slot 111 to realize the synchronous rotation of the control handle 11 and the transmission member 121. Rotating the control handle 11 drives the transmission member 121 to rotate synchronously, and the meshing connection between the transmission tooth 123 and the rack 124 is used to realize the up and down movement of the movable member 122.

[0053] Specifically, a convex ring 126 is provided on the outer wall of the transmission member 121, and a limiting frame 15 is provided on the outer side of the convex ring 126. The limiting frame 15 includes an annular connecting portion 151 provided on the outer side of the convex ring 126, and a receiving portion 152 symmetrically connected to both sides of the connecting portion 151. A spring 153 and a steel ball 154 are provided on the inner side of the receiving portion 152. The spring 153 drives the steel ball 154 to abut against the outer wall of the convex ring 126. Under the elastic force of the spring 153, the steel ball 154 applies pressure along the axial direction of the transmission member 121 to the convex ring 126, thereby increasing the rotation resistance of the transmission member 121 and preventing the transmission member 121 from rotating without external force. Specifically, the outer wall of the convex ring 126 is provided with recessed positions 127 that cooperate with the steel balls 154. There are four recessed positions 127 distributed in a circular array on the outer wall of the convex ring 126. When the transmission member 121 rotates a certain angle, the steel balls 154 will slide into the recessed positions 127 to lock the control handle 11.

[0054] See also Figure 8 As shown, the swing arm mechanism 20 includes a connecting plate 21 and a swing arm 22 rotatably connected to the connecting plate 21 at one end; the swing arm 22 is provided with a slide groove 221 extending along its own length direction, and the swing arm 22 is provided with a notch 222 extending along its own width direction and connected to the slide groove 221.

[0055] Specifically, a rotating shaft 211 is fixedly provided on the connecting plate 21, one end of the swing arm 22 is rotatably connected to the rotating shaft 211, and the swing arm 22 can rotate around the rotating shaft 211. A positioning shaft 212 is fixedly provided on the connecting plate 21, and a torsion spring 23 is sleeved on the outer side of the rotating shaft 211, one end of the torsion spring 23 is cooperatively connected to the swing arm 22, and the other end of the torsion spring 23 is cooperatively connected to the positioning shaft 212. Under the action of the torsion spring 23, the swing arm 22 can be automatically recovered. Specifically, a symmetrically distributed abutment surface 223 is provided at the bottom end of the swing arm 22. When the swing arm 22 swings a certain angle, the abutment surface 223 will abut against the positioning shaft 212 to limit the swing angle of the swing arm 22.

[0056] See also Figure 1-2 As shown, a transmission pin shaft 31 and a connecting pin 32 are provided on one side of the transmission rod 30; the plug-in 13 is cooperatively connected with the transmission pin shaft 31, and the linkage assembly 12 drives the transmission rod 30 to move up and down in the vertical direction; the connecting pin 32 is slidably connected in the slide groove 221, and the transmission rod 30 moves up and down to adjust the position of the connecting pin 32 in the slide groove 221.

[0057] The working principle of the micro-ventilation control device of the utility model is as follows: the control handle 11 is turned, the transmission member 121 rotates synchronously, the transmission tooth 123 is meshed with the rack 124, so that the movable member 122 moves up and down, thereby driving the plug-in 13 to move up and down; because the plug-in 13 is connected with the transmission pin 31, the transmission rod 30 moves up and down synchronously with the movable member 122 through the transmission pin 31, driving the connecting pin 32 to slide in the slide slot 221 of the swing arm 22, thereby adjusting the state of the window.

[0058] like Fig. 9 As shown, the connecting pin 32 is driven to move to the starting position a; the window is opened, and as the window opens, the swing arm 22 swings a certain angle, and at the same time the connecting pin 32 moves to position b in the slide slot 221, and the height of the connecting pin 32 is higher than the height of the notch 222, specifically located at the upper end point of the slide slot 221, so that the opening and closing angle of the window is limited, and the window can only be opened to a certain angle to achieve micro-ventilation.

[0059] like Fig.10 As shown, the connecting pin 32 is driven to move to the starting position c to open the window. As the window opens, the swing arm 22 swings a certain angle, and at the same time, the connecting pin 32 moves to the position d in the slide groove 221. At this time, the connecting pin 32 is flush with the notch 222, and the connecting pin 32 can be separated from the notch 222 and the slide groove 221, so that the transmission rod 30 is separated from the swing arm 22, and the window can be opened.

[0060] Compared with the prior art, the micro-ventilation control device involved in the utility model is applied to micro-ventilation windows, and is provided with a control mechanism, a swing arm mechanism and a transmission rod, which realize the state switching between locking, fully opening the window and micro-ventilation through mutual linkage. Specifically, the control mechanism includes a control handle and a linkage assembly, the swing arm in the swing arm mechanism is provided with a slide groove and a notch, and the transmission rod is provided with a connecting pin; under the mechanical transmission of the linkage assembly, rotating the control handle can realize the up and down movement of the transmission rod, and then adjust the relative position of the connecting pin and the notch; after the swing arm is swung to the maximum angle, when the height of the connecting pin is higher than the notch, the opening and closing angle of the window is limited to realize micro-ventilation; when the connecting pin is at the height of the notch, the connecting pin is disengaged from the swing arm, and the window is fully opened, so as to quickly control the switching between different opening and closing states of the micro-ventilation window.

[0061] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
