[0003] Prior art includes a utility model with publication number CN204175149U, which discloses a dustproof shutter frame. The patent adopts a window frame main body, a roller is provided at the bottom of the window frame main body, a plastic film roll is sleeved on the roller, and a hook is provided at the top of the window frame main body; the improved dustproof shutter frame has a simple structure and is easy to operate, realizes diversified functions of the window frame, has low investment cost, and has good dustproof effect, so as to solve the problem that the existing shutters are composed of multiple groups of horizontal bars, which have good permeability and can only be used for shielding or ventilation effects, and are difficult to achieve dustproof.

[0004] The inventor discovered in his daily work that in the process of using shutter frames for ventilation, there are existing dust-proof shutter frames such as the above-mentioned ones that use plastic film for dust prevention. Since the plastic film is not air-permeable, when the residents unfold the film, the ventilation effect of the shutter frame will be reduced. At the same time, since the fixed structure of the above-mentioned window frame is arranged above the window frame, the user needs to be of a higher height during actual operation. At the same time, in the process of recycling the plastic film, the residents need to manually rotate the roller to realize the recycling operation of the plastic film. Since the length of the plastic film is adapted to the specifications of the window frame, the residents take a long time to recycle the plastic film. Utility Model Content

[0023] The specific settings and functions of the auxiliary component 3 and the operating component 4 are described in detail below.

[0024] In this embodiment: the auxiliary component 3 includes a storage box 31, which is fixedly connected to the side surface of the front panel 2, and the inner wall of the storage box 31 is rotatably connected to a rotating shaft 32, and the surface of the rotating shaft 32 is provided with a fixing groove, and the inner wall of the rotating shaft 32 located in the fixing groove is fixedly connected with a gauze 33, and the inner wall of the storage box 31 is installed with a spiral spring 34.

[0025] Specifically, the arc surface of the rotating shaft 32 is fixedly connected with a stop plate 35 , and a slot 36 is opened on the arc surface of the rotating shaft 32 . The stop plate 35 is provided to limit the position of the rotating shaft 32 , thereby increasing the stability of the rotating shaft 32 in the storage box 31 .

[0026] Specifically, the mesh 33 contacts the inner wall of the storage box 31 , there are two spiral springs 34 , the two spiral springs 34 are symmetrically arranged about the rotating shaft 32 , and the spiral springs 34 are plugged into the inner wall of the slot 36 .

[0027] In this embodiment, a gauze net 33 is provided, and the opened shutter frame can be protected by unfolding and fixing the gauze net 33.

[0028] Specifically, there are two abutment plates 35, which are symmetrically arranged about the rotating shaft 32. The abutment plates 35 abut against the inner wall of the storage box 31, and the rotating shaft 32 is set. Through the cooperation of the rotating shaft 32 and the spiral spring 34, the gauze 33 can be automatically collected and reset when the gauze 33 loses its constraint.

[0029] In this embodiment: the operating component 4 includes a restraining bar 41, which is arranged on the side surface of the front panel 2, and a mounting groove is opened on the side surface of the restraining bar 41. A positive magnet 42 is arranged on the inner wall of the mounting groove of the restraining bar 41, and a cover plate 43 is bolted to the inner wall of the mounting groove of the restraining bar 41. A fixing groove is opened on the side surface of the front panel 2, and a negative magnet 44 is fixedly connected to the inner wall of the fixing groove of the front panel 2.

[0030] In this embodiment, a restraining bar 41 is provided, through which the movable end of the gauze 33 can be restricted to ensure that the movable end of the gauze 33 is outside the storage box 31 .

[0031] Specifically, a handle 45 is fixedly connected to the side surface of the restraint bar 41, a guide rail 46 is fixedly connected to the side surface of the front panel 2, a rubber strip 47 is fixedly connected to the inner wall of the guide rail 46, and a handle 45 is provided, through which the resident can operate the restraint bar 41 and pull the mesh 33 with the cooperation of the restraint bar 41.

[0032] Specifically, the gauze 33 is fixedly connected to the side surface of the restraint bar 41 , the restraint bar 41 is slidably connected to the surface of the guide rail 46 , the cover plate 43 abuts against the side surface of the front panel 2 , and the rubber strip 47 abuts against the side surface of the gauze 33 .

[0033] In this embodiment, a guide rail 46 is provided to guide the moving direction of the restraining bar 41 so as to ensure the stability of the restraining bar 41 during the movement.

[0034] Working principle: When the blinds are opened, the handle 45 is pulled, and the handle 45 is forced to pull the restraining bar 41, and the restraining bar 41 is forced to pull the gauze 33 under the guidance of the guide rail 46, and at the same time, the positive magnet 42 is driven to move by the restraining bar 41, and the gauze 33 is gradually unfolded under the action of the restraining bar 41. When the gauze 33 is unfolded, it pulls the rotating shaft 32, and the rotating shaft 32 is forced to drive the volute spring 34 to rotate. The volute spring 34 is gradually tightened during the rotation process. When the restraining bar 46 is opened, the positive magnet 42 is driven to move by the restraining bar 41, and the gauze 33 is gradually unfolded under the action of the restraining bar 41. When the positive pole magnet 42 moves to the maximum spacing, the screen 33 is fully unfolded and attached to the rubber strip 47, and the positive pole magnet 42 moves to the top of the negative pole magnet 44 and is attracted to the negative pole magnet 44. Then, under the action of the positive pole magnet 42 and the negative pole magnet 44, the position of the restraining bar 41 and the screen 33 can be restricted, so that the screen 33 can isolate the dust passing through the blinds; when the screen needs to be retracted, the handle 45 is pushed, and the handle 45 is forced to push the restraining bar 41. The gear bar 41 and the constraint gear bar 41 are driven by the positive magnet 42 to move. The positive magnet 42 separates from the negative magnet 44 during the movement and loses the restriction on the constraint gear bar 41 and the gauze 33. The gauze 33 loses the tension applied to the rotating shaft 32 while losing the restriction. The rotating shaft 32 loses the force applied to the volute spring 34. The volute rebounds while losing the force and drives the rotating shaft 32 to rotate during the rebound. The rotating shaft 32 pulls the gauze 33 during the rotation. The gauze 33 is pulled and gradually wound around the rotating shaft 32. At the same time, the constraint gear bar 41 is pulled and displaced by the gauze 33. When the constraint gear bar 41 moves to the maximum spacing, the gauze 33 will be completely wound around the rotating shaft 32. By setting the auxiliary component 3 and the operating component 4, the shutter frame can isolate dust, thereby reducing the problem of auxiliary operation of dustproof structure recovery when the shutter frame is in use, and further improving the convenience of the shutter frame in actual use.
