[0002] A rainproof and sound-insulating louver door is a common doorframe shield, which can effectively prevent rainwater from entering the room. At the same time, sound-insulating materials (such as sound-insulating cotton) are provided on the blades, which can effectively reduce noise. At the same time, the gaps between the blades can fully ensure the air circulation between indoor and outdoor, contribute to ventilation and air permeability, and realize heat exchange between indoor and outdoor. It is usually used in positions such as building walls and computer room entrances. Traditional rainproof and sound-insulating louver doors generally include a doorframe and a plurality of blades arranged in the doorframe. Connecting columns protrude from both ends of the blades, and the connecting columns are rotatably installed on opposite sides of the doorframe. When in use, the size of the gap between two adjacent blades is changed by adjusting the rotation angle of the blades. In the traditional louver door structure, the doorframe is composed of two opposite "匚"-shaped baffles. During installation, the connecting columns on the same side of all the blades need to be inserted into the jacks on one side baffle of the doorframe first, and then the other baffle on the doorframe is installed so that the connecting columns at the other ends of the blades are inserted into the jacks on the other baffle. After the two baffles of the doorframe are installed in place, all the blades are locked in the doorframe. The above-mentioned louver door has certain drawbacks. For example, when a damaged blade needs to be replaced, the user needs to disassemble the doorframe. At this time, all the blades are also removed, which brings inconvenience to the blade replacement operation, has low replacement efficiency, and reduces the user experience. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that in the prior art, when replacing a certain blade, it is usually necessary to remove all the blades together, and the replacement process is relatively troublesome, and the user experience is poor.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a rainproof and sound-insulating louver door which is convenient for replacing blades, including a doorframe, blades and a traction strip. A plurality of the blades are arranged in the doorframe in a stacked manner along the longitudinal direction. A plurality of slots are longitudinally opened on opposite sides of the front frame surface of the doorframe, and each slot is inclined from top to bottom. Connecting shafts protrude from opposite sides of the blade, and the connecting shafts can slide obliquely downward from the notch on the front frame surface of the slot to the bottom of the slot. A baffle is detachably installed on the front frame surface of the doorframe, and a convex strip matching the slot is protruded on the baffle. The traction strip is rotatably connected to one side of each blade.

[0005] Furthermore, the plurality of slots are parallel to each other, the number of the slots on one side of the front frame surface is the same as the number of the slots on the other side, and the slots on both sides of the front frame surface correspond to each other one by one.

[0006] Furthermore, there is a gap between the end of the convex strip and the outer peripheral surface of the connecting shaft.

[0007] Furthermore, the upper and lower ends of the baffle are fixedly connected to the front frame surface respectively by fixing bolts.

[0008] Furthermore, a first connecting piece is connected to the traction bar at equal intervals along its length direction, a second connecting piece parallel to the first connecting piece is connected to the edge of one side of the blade, a rotating bolt is rotatably installed between the first connecting piece and the second connecting piece, and a locking nut is installed at one end of the rotating bolt.

[0009] Furthermore, the distance between two adjacent rotating bolts is the same as the distance between two adjacent upper and lower connecting shafts.

DETAILED DESCRIPTION

[0025] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0026] See also Figure 1-Figure 11 The utility model provides a rainproof and soundproof shutter door with easy blade replacement, including a door frame 1, blades 2 and a traction strip 3. The blades 2 have multiple blades, and the multiple blades 2 are stacked in sequence along the longitudinal direction and have the same opening and closing angles. The traction strip 3 connects the multiple blades 2 and is used to control the opening and closing angles of the blades 2.

[0027] The door frame 1 is a quadrilateral frame structure, including two upper and lower side panels and two left and right side panels. The door frame 1 has a front frame surface 101 and a rear frame surface 102 that are arranged opposite to each other. In order to facilitate the description of the positions of the front and rear frame surfaces, the shutter door is in a closed state as an example. The front frame surface 101 is the side of the shutter door facing the outside, and the rear frame surface 102 is the side of the shutter door facing the inside. Figure 7 A plurality of slots 11 are longitudinally provided on opposite sides of the front frame surface 101, each slot 11 is tilted from top to bottom, and the plurality of slots 11 are parallel to each other. The number of slots 11 on one side of the front frame surface 101 is the same as the number of slots 11 on the other side, and the slots 11 on both sides of the front frame surface 101 correspond one to one.

[0028] See also Fig. 9 The blade 2 is a flat plate structure, and a connecting shaft 21 is protruding from the middle of the opposite sides of the blade 2. The connecting shaft 21 can slide obliquely downward from the notch located on the front frame surface 101 of the slot 11 to the bottom of the slot 11. When the connecting shafts 21 on both sides of the blade 2 slide into the slot 11, the blade 2 is mounted on the opposite left and right side panels of the door frame 1, and the bottom of the slot 11 can stably support the connecting shaft 21 to install the blade 2 on the door frame 1. The slot 11 is set as a downwardly inclined structure to ensure that the connecting shaft 21 entering the slot 11 is located at the bottom of the slot 11, effectively preventing the connecting shaft 21 from easily detaching from the slot 11.

[0029] Two baffles 5 are detachably mounted on the front frame surface 101 of the door frame 1, and the two baffles 5 are respectively mounted on the left and right side panels of the door frame 1. A plurality of convex strips 51 are convexly mounted on the baffle 5 in the longitudinal direction, and the number of the convex strips 51 is the same as the number of the slots 11, and one convex strip 51 cooperates with one slot 11. When installed, the convex strip 51 is inserted into the corresponding slot 11, thereby blocking the connecting shaft 21 at the bottom of the slot 11. After the baffle 5 is installed in place, there is a narrow gap between the end of the convex strip 51 and the outer peripheral surface of the connecting shaft 21, so that the convex strip 51 will not squeeze and fix the connecting shaft 21 at the bottom of the slot 11, ensuring that the connecting shaft 21 can rotate freely on the bottom wall of the slot 11 to adjust the opening and closing angle of the blade 2.

[0030] In this embodiment, the upper and lower ends of the baffle 5 are fixedly connected to the front frame surface 101 by fixing bolts 52. When the user needs to replace the blade 2, he only needs to remove the fixing bolts 52 to remove the baffle 5 from the door frame 1, and then take out the blade 2 that needs to be replaced along the slot 11, while the other blades 2 that do not need to be replaced remain in their original positions. The operation is simple and convenient, which greatly improves the replacement efficiency. In other embodiments not shown, the baffle 5 can also be connected to the door frame 1 in a detachable manner such as magnetic adsorption or snap connection, which is not limited here.

[0031] See also Figure 3 , Figure 5 The traction bar 3 is vertically arranged on one side of the blade 2 located on the rear frame surface 102, and the traction bar 3 is rotatably connected to one side of each blade 2. In this way, when the traction bar 3 is moved up and down, all the blades 2 can be deflected synchronously to adjust the opening and closing angles of the blades 2. As a preferred embodiment, the traction bar 3 is connected with first connecting pieces 31 at equal intervals along its length direction, and the edge of one side of the blade 2 is connected with a second connecting piece 22. The first connecting piece 31 and the second connecting piece 22 are parallel to each other, and a rotating bolt 23 is rotatably installed between the first connecting piece 31 and the second connecting piece 22. The distance between two adjacent rotating bolts 23 is the same as the distance between the upper and lower two adjacent connecting shafts 21. A locking nut 24 is installed at one end of the rotating bolt 23. At this time, the first connecting piece 31 and the second connecting piece 22 are clamped between the nut and the locking nut 24 of the rotating bolt 23, and the first connecting piece 31 and the second connecting piece 22 are not clamped and fixed, so that the first connecting piece 31 and the second connecting piece 22 are hinged to each other through the rotating bolt 23. In this way, the rotatable relationship between the blade 2 and the traction bar 3 is realized.

[0032] When a blade 2 needs to be replaced, after removing the baffle 5, the locking nut 24 at the position of the corresponding blade 2 can be removed to further remove the blade 2 from the traction bar 3, while the connection relationship between other blades 2 and the traction bar 3 is not destroyed.

[0033] As a preferred embodiment, a knob piece 241 is connected to the outer wall opposite to the locking nut 24 along the radial direction of the rotating bolt 23. The knob piece 241 is pinched by the user to rotate the locking nut 24, which facilitates the user's operation.

[0034] In the present embodiment, when adjusting the opening and closing angle of the blade 2, the locking nut 24 does not press and fix the first connecting piece 31 and the second connecting piece 22. After the opening and closing angle of the blade 2 is adjusted, the user can tighten at least one locking nut 24 to press and fix the corresponding first connecting piece 31 and the second connecting piece 22. At this time, the corresponding blade 2 and the traction strip 3 cannot move relative to each other. At this time, the position of the blade 2 is locked, which can effectively prevent the blade 2 from easily deflecting. The structural design is reasonable, and the operation is simple and convenient.

[0035] The utility model discloses a rainproof and soundproof shutter door which is easy to replace blades. When a user needs to replace a blade 2, there is no need to completely disassemble the door frame 1. The user only needs to remove the baffle 5 installed on the front frame surface 101, and then release the connection between the corresponding blade 2 and the traction strip 3, so that the blade 2 to be replaced can be removed, while the positions of other blades 2 will not be affected and remain in their original positions. Compared with the traditional replacement method, the operation is simpler and more convenient, the replacement efficiency is high, and the user experience is greatly improved.

[0036] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
