Description

Technical Field

[0001] The present application relates to the field of shed roofs, and in particular to a louver blade, a louver shed roof and a viewing shed. Background Art

[0002] As a new type of shed roof, the shutter shed is mainly composed of a shed frame and multiple shutter blades linearly distributed on the shed frame. The multiple shutter blades can be rotated synchronously through a linkage mechanism, so that when the shutter blades are tilted, the shed roof can be opened, and when the shutter blades are generally set horizontally, the shed roof can be closed. Due to the convenience of using shutter sheds, they are often used in some outdoor furniture such as viewing sheds and folding sheds.

[0003] When the existing louvered shed is switched from a closed state to an open state, if there is water remaining on the surface of the louver blades, the water is likely to drip into the room along the inclined louver blades, resulting in a poor user experience. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a louver, a louver roof and a viewing shed, which can reduce dripping when the louver is rotated and opened, thereby improving the user experience.

[0005] In the first aspect, an embodiment of the present application provides a louver, which includes a sheet-shaped body, a drainage groove is arranged on one side of the body, the drainage groove includes a groove wall located on the outside of the body, and a baffle is also arranged on the top of the groove wall; when the body is horizontally arranged, the top of the groove wall is not higher than the top surface of the louver, and the baffle can switch between a natural state and a stressed state, the top of the baffle in the natural state is higher than the top of the groove wall, and the baffle can lower the height of its top in the stressed state.

[0006] Among them, a drainage groove is provided on one side of the louver, and a baffle is also provided on the top of the groove wall of the drainage groove. When the louver is rotated toward the direction of the drainage groove to an open state, the louver is not subject to the pressure of other louvers. The baffle on the louver is in a natural state, and the top of the baffle is higher than the top of the groove wall, thereby raising the groove wall. The water remaining on the top surface of the louver can flow into the drainage groove under the blocking effect of the baffle, reducing the probability of water dripping under the louver (indoors), playing an anti-drip effect, and improving the user experience.

[0007] When multiple louvers are arranged side by side in a closed state, the louvers can be arranged horizontally, and the baffles on the outside of the louvers can be switched to a stressed state under the pressure of the adjacent louvers to reduce the height of the top of the baffles, so that the adjacent louvers can overlap in position to form a flat louver top surface. Since the top of the louver groove wall (the opening height of the drainage groove) is not higher than the top surface of the louver, the water on the top surface of the louver (mainly rainwater, but also water generated by flushing the top surface of the louver) will flow to the drainage groove at a lower position, so as to achieve the centralized collection and discharge of water flow; in addition, even if the water storage capacity of the drainage groove reaches a full storage state, the water in the drainage groove is difficult to invade the top surface of the louver, so that when there are components such as solar panels on the top surface of the louver, the probability of water soaking the solar panels and other components can be effectively reduced, and the components can be effectively protected.

[0008] In a possible implementation, the baffle is an elastic baffle, which can be deformed under stress to reduce the height of its top. The elastic baffle plays a role of preventing water dripping in a natural state, and the elastic baffle can be deformed under stress to reduce the size along the thickness direction of the body, thereby reducing the height of its top. Moreover, when the elastic baffle is deformed and can be stuck between adjacent louvers, it plays a sealing role.

[0009] In a possible implementation, the cross-sectional shape of the elastic baffle in the natural state is linear or annular. The cross-sectional shapes of the elastic baffle in the natural state are diversified, and these elastic baffles can not only play a role in preventing water dripping when the louver blades are open, but also be easily pressed and deformed when the louver blades rotate, thereby not affecting the rotation of the louver blades to the closed state.

[0010] In a possible implementation, the installation position of the elastic baffle on the groove wall is the inner side, the top, or the outer side of the groove wall. The installation position of the elastic baffle can be flexibly selected according to actual conditions.

[0011] In a possible implementation, the bottom end of the elastic baffle is clamped or bonded to the groove wall; and / or the elastic baffle passes through the groove wall. The installation method of the elastic baffle can be flexibly selected according to actual conditions.

[0012] In a possible implementation, the elastic baffle is made of at least one of rubber, silicone, PVC, elastomer TPE, TPR plastic, and polyurethane. The elastic baffle has a wide range of material choices, has a certain elasticity, can maintain a natural state to catch dripping water, and is easily deformed to a stressed state when stressed, and easily restored to a natural state.

[0013] In a possible implementation, the baffle is a hard baffle, which is hinged to the groove wall. The hard baffle can rotate around the hinge to reduce the height of its top under stress, and the hard baffle can switch to a natural state when the louver rotates toward one side of the drainage groove. The hard baffle plays a role in preventing dripping in the natural state, and the hard baffle is easy to switch to a stress state.

[0014] In a possible implementation, the hard baffle is disposed at the top of the groove wall and is hinged to the top of the groove wall. The hard baffle is easy to install and can rotate, thereby reducing the impact on the drainage groove.

[0015] In a possible implementation, when the louver rotates toward one side of the gutter, the hard baffle can be switched to a natural state under the action of gravity; or, a reset member is provided between the hard baffle and the body, and the hard baffle can be switched to a natural state under the action of the reset member. Among them, the elastic baffle is easy to return to the natural state, thereby playing a role in preventing dripping.

[0016] In a possible implementation, the baffle is a hard baffle, which is connected to the drain groove via a reset member, and the hard baffle can move along its height direction to reduce the height of its top under a force state, and the reset member can drive the hard baffle to switch to a natural state. The hard baffle has little effect on the structure of the drain groove, and the hard baffle plays a role in preventing dripping in the natural state.

[0017] In a possible implementation, the hard baffle penetrates the groove wall, and the bottom end of the hard baffle extends into the drainage groove and is connected to the drainage groove through a reset member. The hard baffle is easy to install and has good stability in state switching.

[0018] In a possible implementation, the top of the groove wall has a flange extending into the interior of the drainage groove, and the baffle is arranged on or near the flange. The flange can cover a part of the opening of the drainage groove, reduce the situation where water flows out of the drainage groove due to excessive turbulence of the water flow in the drainage groove, and play a role in waterproofing and stabilizing the flow; the flange facilitates the installation of the baffle at this position and can provide a certain support for the baffle arranged at this position.

[0019] In a possible implementation, the flange is horizontally arranged or has an upward tilting trend toward its free end. The flange has an upward tilting trend toward its free end, which can provide a space for the side edge of the adjacent louver to avoid rotation. The upward tilting flange can cooperate with the side edge of the adjacent louver (specifically, it can be a bent waterproof edge), so that the rotation between the adjacent louvers will not interfere with each other, and the purpose of achieving a more compact structure after the adjacent louvers are combined can be achieved. In addition, the gap between the two can be reduced, and rainwater can be reduced from entering the shed through the gap between the flange and the side edge of the adjacent louver (specifically, it can be a bent waterproof edge), thereby improving the waterproof sealing performance between the louvers.

[0020] In a possible implementation, the body is provided with a waterproof edge extending downward on the other side of the drainage groove, the bottom end of the waterproof edge is lower than the top end of the groove wall, and the waterproof edge of the louver can press the baffle of the adjacent louver to switch it to a stressed state. The waterproof edge increases the rotation space of the adjacent louvers when they rotate synchronously, avoiding interference between the waterproof edge and the groove wall between the adjacent louvers and affecting the normal rotation of the two; when the louvers rotate to close, the waterproof edge of the adjacent louvers can easily press the baffle to switch to a stressed state.

[0021] In a possible implementation, a sealing strip is provided on the lower surface of the body near the waterproof edge and / or on the upper surface of the flange. When the louvers are rotated to a closed state, the gaps between adjacent louvers can be sealed, thereby improving the waterproof sealing performance between the louvers. In the case where the sealing strip is combined with an elastic baffle, a double sealing effect can be achieved, thereby further enhancing the waterproof sealing performance between the louvers.

[0022] In a possible implementation, a card slot is provided on the lower surface of the body near the waterproof edge, the card slot extends along the length direction of the body, and a sealing strip is clamped in the card slot. The sealing strip can be easily clamped and set through the card slot, and the sealing strip can also be easily disassembled and replaced.

[0023] In a possible implementation, the top of the baffle in a natural state is higher than the same side edge of the top surface of the louver; optionally, the top of the baffle in a natural state is 1-50 mm higher than the same side edge of the top surface of the louver. The top of the baffle is higher than the same side edge of the top surface of the louver, which can better play the role of anti-drip effect. When the louver rotates toward the drainage groove, the raised baffle can catch the water dripping from the top surface of the louver and make it flow into the drainage groove.

[0024] In a possible implementation, the top surface of the baffle in the natural state is flush with the same side edge of the top surface of the louver, or the top surface of the baffle in the natural state is lower than the same side edge of the top surface of the louver; optionally, the top surface of the baffle in the natural state is 0-3mm lower than the same side edge of the top surface of the louver. When the louver rotates within a specific angle range toward the drainage groove, the baffle can still play a drip-proof effect and catch water dripping from the top surface of the louver.

[0025] In a possible implementation, the baffle is inclined at an angle of 45°-100° relative to the top surface of the louver blade in a natural state; optionally, the baffle is inclined at an angle of 60°-90° relative to the top surface of the louver blade in a natural state. The elastic baffle is inclined at a certain angle relative to the horizontally arranged body (louver blade), which not only plays a role in preventing dripping, but also when the louver blades rotate synchronously to the closed state, the louver blades can easily press the baffles on the adjacent louver blades to switch them to a stressed state, thereby not affecting the closing effect between the adjacent louver blades.

[0026] In a possible implementation, the body is a metal profile, and the cross section is a frame structure; optionally, a broken bridge structure is provided in the frame structure. The metal profile with a frame structure cross section has the advantages of light weight and high strength, is suitable for forming a roof, and is also convenient for setting a drainage trough; the body with a broken bridge structure has good thermal insulation performance, reducing heat conduction between indoors and outdoors through the body.

[0027] In a possible implementation, the bottom of one side of the main body extends outward to form a groove bottom, and the groove bottom bends and extends upward to form a groove wall. The main body, the groove bottom and the groove wall together constitute a drainage groove, and the drainage groove has a diversion opening facing upward, and the diversion opening is not higher than the top surface of the main body.

[0028] In a possible implementation, the maximum length of the baffle that can be extended into the gutter under stress is not greater than the width of the narrowest position in the gutter. When multiple louvers are simultaneously rotated to the closed state, the baffle can be pressed by adjacent louvers to extend into the gutter. The baffle extending into the gutter can serve as a structure to block the water flow in the gutter, and together with the waterproof edge at this position, it plays a role in blocking the water flow in the gutter from rushing out. By setting the maximum length that the baffle can extend into the gutter to be not greater than the width of the narrowest position in the gutter, it is ensured that the baffle can go out of the gutter and return to a natural state when the louvers are rotated to the open state to play a role in preventing dripping.

[0029] In a possible implementation, the width of the narrowest position in the drainage groove is 20-100 mm, and can be optionally 30-50 mm.

[0030] In a possible implementation, the top of the baffle in a natural state is 5-80 mm higher than the top of the groove wall, and optionally 20-30 mm.

[0031] In a possible implementation, the baffles are continuously or discontinuously arranged along the length direction of the body, wherein the arrangement form and length of the baffles can be set according to the anti-drip requirements of the louver blades.

[0032] In a possible implementation, the top surface of the body is a continuous surface, and the continuous surface constitutes the top surface of the louver. In the case where no solar panels are provided, the continuous surface of the body serves as the top surface of the louver, and water on the top surface can be drained away in time to avoid water accumulation caused by the depression of the top surface of the body.

[0033] In a possible implementation, a solar panel is also installed on the main body, and the upper surface of the solar panel constitutes the top surface of the louver. In the case of installing a solar panel, the louver formed by the solar panel installed on the main body can be used as a solar power generation unit to improve energy utilization.

[0034] In a possible implementation, a receiving groove for installing a solar panel is provided on the body, and the solar panel is snapped into the receiving groove; or, the solar panel is detachably mounted on the body by fasteners. The receiving cavity facilitates snap-on installation of the solar panel. Alternatively, the solar panel can be directly mounted on the body, thereby improving the utilization rate of the solar panel.

[0035] In the second aspect, an embodiment of the present application provides a louver roof, which includes a frame and a plurality of louvers provided in the first aspect, wherein both ends of the louver are respectively rotatably connected in the frame, and the plurality of louvers are distributed in parallel on the frame; when the plurality of louvers are in a closed state on the frame, one of the louvers presses a baffle of an adjacent louver relative to the other side of the drainage groove, so that the baffle switches to a stressed state; when the louver rotates to an open state, the baffle of the louver switches to a natural state.

[0036] Among them, when multiple louvers are in closed state, they can be used as a protective roof. When the louvers are in open state, they can play a ventilation effect. The baffles can prevent water from dripping in a natural state, so that water on the top of the louvers will not drip directly, but flow into the drainage groove, thereby increasing the user experience.

[0037] In a possible implementation, a waterproof edge extending downward is provided on the other side of the louver body relative to the drainage groove. When the louver is arranged horizontally, the bottom end of the waterproof edge is lower than the top end of the groove wall. When multiple louvers are in a closed state, the waterproof edge of one louver is correspondingly inserted into the drainage groove of an adjacent louver. When multiple louvers are in a closed state, the waterproof edge is inserted into the drainage groove of an adjacent louver, and the water flow in the drainage groove is blocked by the waterproof edge.

[0038] In a possible implementation, the baffle is an elastic baffle, and when the multiple louvers are in a closed state, one of the louvers presses the elastic baffle of the adjacent louver relative to the other side of the drainage groove so that the elastic baffle extends into the drainage groove. When the multiple louvers are in a closed state, the elastic baffle is deformed and inserted into the drainage groove of the adjacent louver, and the deformed elastic baffle plays a better sealing role.

[0039] In a possible implementation, the louvered roof further includes a linkage mechanism, which includes a linear telescopic rod and a linkage bar, one end of the plurality of louvers is hinged on the linkage bar, one end of the linear telescopic rod is hinged on the scaffold, and the other end is hinged on the linkage bar, so as to drive the linkage bar to move and drive the plurality of louvers to rotate around the hinge point between the scaffold and the scaffold. When the linear telescopic rod moves in a telescopic manner, it drives the movable bar to move, and the plurality of louvers are hinged to the movable bar, and the louvers are also connected to the scaffold in rotation, so that when the linkage bar moves, the plurality of louvers will be driven to rotate synchronously, thereby switching the louvers between the open state and the closed state.

[0040] In a possible implementation, a drainage channel is provided below the same end of all louvers, and the drainage channel is provided with a water inlet facing the end of the louver, wherein the rainwater that converges from the top surface of the louver into the drainage groove is further collected through the drainage channel and then discharged.

[0041] In a third aspect, the embodiment of the present application provides a viewing shed, which includes a column and a louvered shed roof provided in the second aspect, wherein the louvered shed roof is mounted on the top of the column. The louvered shed roof of the viewing shed has a drip-proof function, which reduces dripping when the louver blades are turned and opened, thereby improving the user experience.

DETAILED DESCRIPTION

[0064] The louvered roof is generally composed of multiple louvers that are arranged in parallel and can rotate independently. When the louvered roof is in a closed state, one side of a louver needs to overlap the gutter on the side of the adjacent louver to form a closed roof structure. In order to allow water on the surface of the roof structure to flow smoothly into the gutter, the opening of the gutter is usually lower than the upper surface of the roof structure. However, when the louver of this structure is rotated to one side of the gutter to open, the louver will tilt toward the gutter, and the position of the gutter will become lower. If there is water on the surface of the louver, the water will easily flow along the surface, pass over the gutter at a lower position and drip directly, that is, dripping occurs.

[0065] In order to reduce the probability of dripping, the structure of the louver needs to be designed to increase the anti-drip function.

[0073] First embodiment

[0074] Please see Figure 1-Figure 4 The present embodiment provides a louver 300, which includes a sheet-shaped body 3000, a drainage groove is arranged on one side of the body 3000, the drainage groove includes a groove wall 302 located on the outside of the body 3000, and a baffle is also arranged on the top of the groove wall 302; when the body 3000 is horizontally arranged, the top of the groove wall 302 is not higher than the top surface of the louver 300, the baffle can switch between a natural state and a stressed state, the top of the baffle in the natural state is higher than the top of the groove wall 302, and the height of the top of the baffle can be reduced in the stressed state.

[0075] In the embodiment of the present application, the louver 300 (main body 3000) is horizontally arranged, which means that the top surface (upward surface) of the louver 300 is horizontal or nearly horizontal. For example, when the middle part of the top surface of the louver 300 is a flat surface (the top surface is mainly composed of the upper surface of the main body 3000 or the upper surface of the solar panel 310), the louver 300 (main body 3000) is horizontally arranged, which means the flat surface is horizontally arranged; or when the top surface of the louver 300 is an arc-shaped surface with the middle part convex upward, the louver 300 (main body 3000) is horizontally arranged, which means the middle part is in the highest position. Compared with the horizontal arrangement, the louver 300 (main body 3000) is tilted, which generally refers to the state after the horizontal arrangement is rotated by a certain angle around the rotation axis arranged along the length direction.

[0076] In the embodiment of the present application, the louver 300 (body 3000) is horizontally arranged and is not limited to the setting state after installation. Since the louver 300 can rotate around the rotation axis arranged along the length direction after installation, the setting state of the louver 300 after installation can be changed. For the convenience of explanation, the louver 300 installed in place is divided into a closed state and an open state. When the louver 300 is in the closed state, the louver 300 is usually arranged horizontally, and can also be slightly tilted to one side or tilted to one end. The edge of the louver 300 overlaps with the edge of the adjacent louver 300 to form a closed roof structure ( Figure 2 The shutter blades 300 in the closed state are rotated toward one side (generally toward the side of the drainage groove) within a certain angle range, so that the shutter blades 300 are in an open state. The shutter blades 300 in the open state are tilted, and there is a spacing gap between adjacent shutter blades 300 ( Figure 4 shown).

[0077] Regarding the shape design of the louver frame (main body 3000) itself, unless otherwise specified, the "top end" in the embodiment of the present application refers to the vertex position when the louver 300 (main body 3000) is horizontally arranged, for example, the top end of the groove wall 302 refers to the vertex of the groove wall 302 when the louver 300 (main body 3000) is horizontally arranged; the height comparison or change refers to the height comparison or change of the louver 300 (main body 3000) when the louver 300 (main body 3000) is horizontally arranged compared to the reference plane below the louver 300 (main body 3000), for example, the top end of the groove wall 302 is not higher than the top surface of the louver 300, which means that the top end of the groove wall 302 is lower than any position of the top surface of the louver 300 or is flush with the top surface of the louver 300 when the louver 300 (main body 3000) is horizontally arranged; the baffle can lower the height of its top end under stress compared to the natural state, and the height of the top end of the baffle under stress compared to the reference plane is less than the height of the top end compared to the reference plane in the natural state.

[0078] The baffle is arranged at the top of the groove wall 302, which means that at least a part of the baffle is located at the top of the groove wall 302, so that the top of the baffle in the natural state is higher than the top of the groove wall 302. The states presented by the baffle are divided into a natural state and a stressed state. The natural state refers to the state when the baffle is not subjected to external force, also known as a non-stressed state. The baffle in the natural state is higher than the top of the groove wall 302, and the top height of the baffle in the stressed state is reduced, and does not completely block the opening of the drainage groove, thereby not affecting the water collection function of the drainage groove. In the embodiment of the present application, when the louver 300 is in the open state, the louver 300 is tilted, and the adjacent louver 300 is separated by one end, and the baffle on the louver 300 is in the natural state; when the louver 300 is in the closed state, the adjacent louver 300 is overlapped together, and the baffle on the louver 300 is in the stressed state.

[0079] In some embodiments of the present application, the baffle is an elastic baffle 340. The top of the elastic baffle 340 is higher than the top of the groove wall 302 in a natural state, and can be deformed to reduce the height of its top under a force state. The elastic baffle 340 can meet at least one of the following requirements:

[0080] In some embodiments of the present application, please refer to Figure 1 , the top of the elastic baffle 340 in the natural state is higher than the same side edge of the top surface of the louver 300. The same side edge of the top surface of the louver 300 refers to the side position of the top surface of the louver 300 close to the elastic baffle 340, which is lower than the elastic baffle 340 in the natural state, so that the water on the top surface of the louver 300 flows smoothly into the drainage groove from the edge, realizing rainwater collection and centralized discharge.

[0081] In a specific embodiment, the top of the elastic baffle 340 in a natural state is 1-50 mm higher than the same side edge of the top surface of the louver blade 300. Exemplarily, the top of the elastic baffle 340 is 1 mm, 3 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm higher than the same side edge of the top surface of the louver blade 300, or an intermediate value between any two values.

[0082] In some other embodiments of the present application, the top surface of the baffle in the natural state can also be flush with the same side edge of the top surface of the louver 300, or the top of the baffle in the natural state is lower than the same side edge of the top surface of the louver 300.

[0083] In a specific embodiment, the top of the baffle in a natural state is 0-3 mm lower than the same side edge of the top surface of the louver blade 300. Exemplarily, the top of the baffle is flush with the same side edge of the top surface of the louver blade 300, or is 1 mm, 2 mm, 3 mm lower or an intermediate value between any two values.

[0084] In some embodiments of the present application, the top of the elastic baffle 340 in the natural state is 5-80 mm higher than the top of the groove wall 302, and can be 20-30 mm. For example, the top of the elastic baffle 340 in the natural state is 5 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 80 mm higher than the top of the groove wall 302, or an intermediate value between any two values.

[0085] In some embodiments of the present application, the elastic baffle 340 has an inclination angle of 45°-100° relative to the top surface of the louver blade 300 in the natural state. Optionally, the elastic baffle 340 has an inclination angle of 60°-90° relative to the top surface of the louver blade 300 in the natural state. For example, the elastic baffle 340 has an inclination angle of 45°, 60°, 70°, 80°, 90°, 100° or an intermediate value between any two values ​​relative to the horizontally arranged body 3000. The inclination angle refers to the inclination angle of the portion of the baffle that is higher than the top of the groove wall 302 in the natural state, and generally refers to the angle between the line between the top and bottom of the portion and the top surface of the louver blade 300.

[0086] In some embodiments of the present application, the cross-sectional shape of the elastic blocking piece 340 in a natural state is linear or annular.

[0087] If there is no specific description, the cross section in the embodiment of the present application refers to the cross section perpendicular to the length direction. For example, the cross section of the elastic blocking piece 340 can be a straight line, an arc or other linear shape, or a frame shape such as a ring.

[0088] In some embodiments of the present application, the material of the elastic blocking piece 340 includes at least one of rubber, silicone, PVC, elastomer TPE, TPR plastic, and polyurethane.

[0089] In the embodiment of the present application, the installation position of the elastic baffle 340 on the groove wall 302 is the inner side, the top or the outer side of the groove wall 302, and there is no specific limitation. In some embodiments of the present application, the bottom end of the elastic baffle 340 is clamped or bonded to the groove wall 302; as an implementation method, the bottom end of the elastic baffle 340 passes through the groove wall 302 and is clamped to the inner wall of the drainage groove.

[0090] In some embodiments of the present application, the elastic blocking piece 340 is continuously or discontinuously arranged along the length direction of the main body 3000 .

[0091] In the embodiment of the present application, the maximum length that the elastic baffle 340 can deform and extend into the drainage groove is not greater than the width of the narrowest position in the drainage groove. The elastic baffle 340 will deform under the action of external force, and it can extend into the drainage groove or outside the drainage groove. When the shutter 300 is closed, the elastic baffle 340 is deformed and extends into the drainage groove under force. In some embodiments of the present application, the maximum length that the elastic baffle 340 can extend after deformation is less than or equal to the width of the narrowest position in the drainage groove, so as to ensure that after the shutter 300 is opened, the external force on the elastic baffle 340 is removed, and it can be restored to a natural state and higher than the top of the groove wall 302, so as to play the function of preventing dripping.

[0092] Based on the above technical solution, the main body 3000 can meet at least one of the following requirements:

[0093] In some embodiments of the present application, please refer to Figure 1 The body 3000 is a metal profile, and the cross section is a frame structure, and a broken bridge structure is arranged inside the frame structure. Both ends of the body 3000 are provided with detachable sealing sheets, which are used to seal the ends of the body 3000.

[0094] As an embodiment, the bottom of one side of the body 3000 extends outward to form a groove bottom, and the groove bottom bends upward to extend to form a groove wall 302. The body 3000, the groove bottom and the groove wall 302 together constitute a drainage groove, and the drainage groove has a diversion opening opening facing upward, and the diversion opening is not higher than the top surface of the body 3000. The width of the narrowest position in the drainage groove (i.e., the width of the diversion opening) is 20-100mm, and can be 30-50mm. Exemplarily, the width of the narrowest position in the drainage groove is 20mm, 30mm, 40mm, 50mm, 60mm, 80mm, 100mm, and can be 30-50mm or an intermediate value between any two values.

[0095] In some embodiments of the present application, the top of the groove wall 302 has a flange 303 extending into the interior of the drainage groove. The flange 303 is horizontally arranged or tends to bend upward toward its free end. The elastic baffle 340 is arranged on or adjacent to the flange 303.

[0096] In some embodiments of the present application, a waterproof edge 301 extending downward is provided on the other side of the main body 3000 relative to the drainage groove, and the bottom end of the waterproof edge 301 is lower than the top end of the groove wall 302. The waterproof edge 301 of the louver 300 can press the elastic baffle 340 of the adjacent louver 300 to switch it to a stressed state.

[0097] Specific reference Figure 1-Figure 4 In this embodiment, the main body 3000 includes a frame body 300a and an extension part. The cross-section of the frame body 300a is trapezoidal, and other embodiments may also be rectangular or other shapes. Most of its interior is a hollow structure, which can reduce the weight of the louver 300 product. The two sides of the upper surface of the frame body 300a extend horizontally outward to form the above-mentioned extension part. Specifically, the extension part includes a first extension edge 300b located on the left side of the frame body 300a and a second extension edge 300c located on the right side of the frame body 300a.

[0098] The sealing pieces at both ends of the frame body 300a are sealed by conventional means such as glue or screws. A waterproof edge 301 is provided on the side of the first extension edge 300b away from the frame body 300a. The lower end of the waterproof edge 301 extends a certain distance toward the bottom of the louver 300. A bent edge (groove bottom + groove wall 302) is integrally formed at the bottom of the other side of the frame body 300a. A drainage groove is formed between the bent edge and the right side of the body 3000. A diversion opening connected to the drainage groove is formed between the top of the groove wall 302 and the second extension edge 300c. The height of the drainage groove is lower than the height of the top surface of the louver 300, that is, the height of the diversion opening is lower than the height of the top surface of the louver 300. The top of the groove wall 302 is lower than the bottom height of the second extension edge 300c, please refer to Figure 2 and Figure 3 When the adjacent first louver 350 and second louver 360 are in a closed state, the first extension edge 300b of the second louver 360 can overlap the top of the groove wall 302 of the first louver 350, and the waterproof edge 301 of the second louver 360 extends into the diversion opening of the first louver 350. When rainwater falls on the louver 300, it will enter the respective drainage grooves, and then the rainwater will be concentrated and drained through the drainage grooves. The above design can effectively prevent rainwater from entering the viewing shed through the gaps between adjacent louvers 300, thereby improving the waterproof sealing performance of the louver shed.

[0099] In order to improve the water storage and waterproofing ability of the drainage trough, in the present embodiment, the top of the groove wall 302 has a flange 303 extending toward the frame body 300a, and the flange 303 is horizontally arranged. The setting of the flange 303 can control the size of the diversion opening to avoid the diversion opening being too large and turbulent splashing out of the diversion opening when rainwater flows in the drainage trough. At the same time, the setting of the flange 303 is also convenient for matching with the waterproof edge 301. When adjacent louvers 300 are horizontally arranged, the waterproof edge 301 can extend into the diversion opening and extend the lower end of the waterproof edge 301 to the lower end of the flange 303. In this way, when rainwater at the upper end of the louver 300 enters the diversion opening through the waterproof edge 301, the risk of rainwater entering the viewing shed through the gap between the waterproof edge 301 and the flange 303 is reduced, thereby improving the waterproof sealing between adjacent louvers 300.

[0100] In this embodiment, an elastic baffle 340 is provided on the horizontally arranged flange 303. The elastic baffle 340 is made of polymethyl methacrylate (PMMA) and has a straight cross-sectional shape. Its bottom end is clamped on the upper surface of the flange 303. The elastic baffle 340 is inclined at an angle of 60° relative to the horizontally arranged main body 3000. The top of the elastic baffle 340 is 20 mm higher than the same side edge of the top surface of the louver blade 300. Please refer to Figure 4When the adjacent first louver 350 and second louver 360 are in an open state, there is a distance between the first louver 350 and the second louver 360, the elastic baffle 340 on the first louver 350 is in a natural state, and the first louver 350 has an anti-drip effect. The residual water droplets on the top surface of the first louver 350 will drip into the drainage groove in the direction indicated by the arrow under the blocking effect of the elastic baffle 340 thereon. Similarly, the second louver 360 also has an anti-drip effect, and the water droplets thereon will drip into the drainage groove in the direction indicated by the arrow, and will not drip under the louver 300.

[0101] In some embodiments of the present application, in order to further improve the connection sealing between adjacent louvers 300 when the louvers 300 are in the closed state, a sealing strip is provided on at least one side of the body 3000. The sealing strip is located on the upper surface of the groove wall 302 or on the lower surface of the body 3000 on the other side relative to the drainage groove, so as to seal the gap between the waterproof edge 301 and the flange 303 of adjacent louvers 300 when multiple louvers 300 are arranged horizontally; the sealing strip is provided on the lower surface of the body 3000 near the waterproof edge 301 and / or on the upper surface of the flange 303. As an embodiment, a card slot 304 is provided on the lower surface of the body 3000 near the waterproof edge 301, and the card slot 304 is extended along the length direction of the body 3000, and a sealing strip is clamped in the card slot 304.

[0102] In this embodiment, please refer to Figure 2 and Figure 3 , the sealing strip is arranged at the bottom of the first extension edge 300b of the first louver 350 and the second louver 360, and a slot 304 arranged along the length direction of the first extension edge 300b can be provided at the bottom of the first extension edge 300b, and then the sealing strip is clamped on the slot 304 to facilitate the disassembly and assembly of the sealing strip, and the sealing strip can be a conventional rubber strip. When the first louver 350 and the second louver 360 are in a closed state, the sealing strip at the bottom of the first extension edge 300b of the second louver 360 will be attached to the flange 303 of the first louver 350, and cooperate with the deformed elastic baffle 340 on the first louver 350 to achieve a double sealing effect, thereby improving the sealing and waterproof properties of the overlapped joint between the first louver 350 and the second louver 360. In other embodiments, the sealing strip can be omitted, and the sealing effect can be achieved by the elastic baffle 340, or a sealing strip can be arranged on the upper surface of the flange 303 at the same time, and cooperate with the deformed elastic baffle 340 to achieve a double sealing effect.

[0103] In some embodiments of the present application, a solar panel 310 is further installed on the body 3000, and the upper surface of the solar panel 310 constitutes the top surface of the louver 300. In some other embodiments, the top surface of the body 3000 is a continuous surface, and the solar panel 310 is not installed, and the continuous surface constitutes the top surface of the louver 300.

[0104] As an optional method, in this embodiment, the louver 300 includes a solar panel 310. During the day, the energy generated by the solar panel 310 is converted by an inverter and other components and stored in a battery, thereby supplying power to the electrical appliances in the viewing shed. The main body 3000 is provided with a receiving groove for installing the solar panel 310. The solar panel 310 is snapped into the receiving groove. Specifically, the first extension edge 300b and the second extension edge 300c are bent upward to form the receiving groove. As another optional method, the solar panel 310 is detachably mounted on the main body 3000 by fasteners.

[0105] Second embodiment

[0106] Please see Figure 5-Figure 8 The louver 300 provided in this embodiment is different from the louver 300 of the first embodiment in that: the flange 303 of the louver 300 tends to bend upward toward its free end, the waterproof sheet is inclined toward the direction of the main body 3000, and an elastic baffle 340 is arranged on the flange 303. The bottom end of the elastic baffle 340 passes through the flange 303 to be fixed on the flange 303. The inclination angle of the elastic baffle 340 relative to the horizontally arranged main body 3000 is 60°, and the top end of the elastic baffle 340 is 10 mm higher than the same side edge of the top surface of the louver 300.

[0107] Please see Figure 6 and Figure 7 When the adjacent first louver 350 and second louver 360 are in a closed state, the first extended edge 300b of the second louver 360 can overlap the flange 303 of the first louver 350, and at the same time, the waterproof edge 301 of the second louver 360 extends into the diversion opening of the first louver 350, and presses the elastic baffle 340 to deform and extend into the drainage groove. The raised flange 303 of the first louver 350 and the inclined waterproof edge 301 of the second louver 360 interact with each other, and the elastic baffle 340 on the first louver 350 has a good squeezing effect, so that the elastic baffle 340 has a better sealing effect, and the elastic baffle 340 extending into the drainage groove is inclined, which has a better water blocking effect in the drainage groove.

[0108] Please see Figure 8When the adjacent first louver 350 and second louver 360 are in an open state, there is a distance between the first louver 350 and the second louver 360, and the elastic baffle 340 on the first louver 350 is in a natural state. The first louver 350 has an anti-drip function. Since the flange 303 of the first louver 350 is tilted, the height of the raised elastic baffle 340 above can be relatively large, thereby achieving a better anti-drip effect. After the first louver 350 is rotated at a large angle toward the drainage groove, the residual water droplets on the top surface of the first louver 350 will drip into the drainage groove in the direction indicated by the arrow under the blocking effect of the baffle bar, and are not easy to drip under the first louver 350.

[0109] Third embodiment

[0110] Please see Fig. 9 The louver 300 provided in this embodiment is different from the louver 300 of the first embodiment in that the cross-section of the elastic baffle 340 is arc-shaped and inclined. The elastic baffle 340 of this form can be easily deformed and extended into the drainage groove under the pressure of the adjacent louver 300, and can easily rebound to a natural state, thereby playing an anti-drip effect.

[0111] Fourth embodiment

[0112] Please see Fig.10 The present embodiment provides a louver 300, which is different from the louver 300 of the first embodiment in that: the elastic baffle 340 is arranged outside the drainage groove, specifically on the outer surface of the groove wall 302, and can be fixed to the surface of the groove wall 302 by bonding, and the flange 303 is installed without destroying the profile structure of the body 3000. The inclination direction of the elastic baffle 340 is consistent with the inclination of the groove wall 302, and the principle of its anti-drip function is similar, which will not be repeated.

[0113] Fifth embodiment

[0114] Please see Fig.11 The louver 300 provided in this embodiment is different from the louver 300 of the first embodiment in that: the top of the groove wall 302 is not provided with a flange 303, and the top of the groove wall 302 is provided with an elastic baffle 340, which extends upward along the groove wall 302 to form a flat side wall structure, making it difficult for users to notice the existence of the elastic baffle 340, but does not affect its anti-drip function.

[0115] Sixth embodiment

[0116] Please see Fig.12The shutter blade 300 provided in this embodiment is different from the shutter blade 300 of the first embodiment in that: the elastic baffle 340 is vertically arranged on the flange 303, and its inclination angle relative to the horizontally arranged main body 3000 is 90°. The bottom end of the elastic baffle 340 penetrates the flange 303 to be fixed on the flange 303; the top end of the elastic baffle 340 is flush with the same side edge (the second extension edge 300c) of the top surface of the shutter blade 300. The groove wall 302 is heightened by the elastic baffle 340, and the anti-drip function can still be played when the shutter blade 300 rotates at a small angle.

[0117] Seventh embodiment

[0118] Please see Fig.13 The shutter blade 300 provided in this embodiment is different from the shutter blade 300 of the first embodiment in that the baffle is a hard baffle 370, which is hinged to the groove wall 302, and the hard baffle 370 can rotate around the hinge to reduce the height of its top under stress. When the shutter blade 300 rotates toward one side of the drainage groove, the hard baffle 370 can switch to a natural state. The hard baffle 370 is arranged at the top of the groove wall 302 and is hinged to the top of the groove wall 302. Specifically, the cross section of the hard baffle 370 is L-shaped, and the lateral end of the hard baffle 370 is hinged to the end of the flange 303, and the flange 303 provides support for the hard baffle 370. When the hard baffle 370 is subjected to thrust (pressure provided by the flange of the adjacent shutter blade), the hard baffle 370 can rotate around the hinge in the direction of the arrow shown in the figure to the stress state. When the shutter blade 300 rotates toward one side of the drain groove, the hard baffle 370 can switch to the natural state under the action of its own gravity. In other embodiments, a reset member can be provided between the hard baffle 370 and the body 3000, which can be a torsion spring, a tension spring, a compression spring, or a spring sheet according to different installation positions. For example, a torsion spring is directly provided at the hinge, and the hard baffle 370 can switch to the natural state under the action of the reset member to improve the stability of switching from the stressed state to the natural state.

[0119] In other embodiments, the material of the hard baffle 370 can be the same metal material as the body, or other hard materials. The installation position and method of the hard baffle 370 can also be other methods. The inclination angle and shape of the hard baffle 370 refer to the inclination angle and shape of the vertical part of the hard baffle 370, which can be the same as the setting of the elastic baffle 340 in the first embodiment. When setting the hard baffle 370, it is necessary to pay attention to that when it is switched to the stressed state, it will not completely cover the drain groove. Specifically, the length of the vertical part of the hard baffle 370 cannot be too large.

[0120] Eighth embodiment

[0121] Please see Fig.14 The present embodiment provides a louver blade 300, which is different from the louver blade 300 of the first embodiment in that: the baffle is a hard baffle blade 370, which is connected to the drainage groove by a reset member 380, and the hard baffle blade 370 can move along its height direction to reduce the height of its top under stress, and the reset member can drive the hard baffle blade 370 to switch to a natural state. In this embodiment, the hard baffle blade 370 passes through the flange 303 at the top of the groove wall 302, and the bottom end of the hard baffle blade 370 extends into the drainage groove and is connected to the drainage groove through a reset member 380 (such as a compression spring). The reset member 380 can be set at one or multiple points. When the hard baffle blade 370 is subjected to pressure (pressure provided by the flange of the adjacent louver blade), the hard baffle blade 370 can move downward in the direction of the arrow shown in the figure to a stressed state, and when the external force of the hard baffle blade 370 is removed, it can be restored to a natural state under the action of the reset member 380.

[0130] In this embodiment, an axial hole 122a and a wire groove are provided on the side of the extension frame 122. Pins are provided at both ends of the louver 300 and correspondingly inserted into the axial hole 122a to enable the louver 300 to be rotatably connected to the beam 120. The wire groove facilitates the routing of the wires.

[0131] In a possible implementation, a drainage channel is provided below the same end of all louvers 300 , the drainage channel is provided with a water inlet facing the end of the louver 300 , and the drainage channel is clamped on the shelf.

[0132] In this embodiment, the viewing shed also includes a drainage channel 130. The drainage channel 130 is a U-shaped structure as a whole. A third clamp 1301 is provided on one side of the drainage channel 130, and the other side extends horizontally toward the interior of the roof space. The U-shaped opening portion is used to receive rainwater flowing in from both ends of the louver 300. The drainage channel 130 and the extension frame 122 are clamped in the second clamp groove 1201a of the side frame 1201 through the third clamp 1301, thereby realizing a detachable clamping connection between the drainage channel 130 and the side frame 1201.

[0133] Specifically, in order to facilitate the disassembly and assembly between the beam cap 121 and the beam 120 and the disassembly and assembly between the drainage channel 130 and the beam 120, refer to Fig. 20 The matching mode between the first clamp 121a and the first bayonet slot 1223 and the matching mode between the third clamp 1301 and the second bayonet slot 1201a are the same in structure. Taking the structure of the third clamp 1301 as an example, the third clamp 1301 includes an elbow portion 1301a and a tightening portion 1301b. The vertical cross-section of the elbow portion 1301a is an outwardly convex arc structure, and the tightening portion 1301b is arranged on one side below the elbow portion 1301a. A matching foot 1201b is arranged on the top of the second bayonet slot 1201a. When the third clamp 1301 is clamped inside the second bayonet slot 1201a, the arc portion of the elbow portion 1301a is correspondingly clamped on the matching foot 1201b, and at the same time, the end of the tightening portion 1301b The part is pressed against the bottom of the second bayonet groove 1201a. Through the assembly between the above-mentioned clamping head and the bayonet groove, the disassembly and assembly of the corresponding components are convenient. The arc part of the elbow 1301a cooperates with the matching foot 1201b of the corresponding bayonet groove to quickly realize the pre-connection of the corresponding components. Then, the pressing part 1301b is pressed against the bottom of the bayonet groove to limit the separation of the clamping head from the bayonet groove in the vertical direction. For some wall-mounted components, such as the drain ditch 130, wall-mounted air conditioner, etc., the drain ditch 130 can be stably fixed on the beam 120 by the weight of the product itself. Compared with some elastic snap-on installation methods, the connection method between the clamping head and the bayonet groove in this embodiment is more convenient for disassembly and assembly of the corresponding product.

[0134] Based on the above embodiments, refer to Fig.17 The connection between the cross beam 120 and the column 110 can be fastened by bolts. Specifically, the column 110 is a hollow tube structure, preferably a rectangular tube, and screw holes 1102 are opened on the sides corresponding to the long beam 120a and the short beam 120b. An opening is provided at the upper end of the column 110. During installation, a right-angle screwdriver is inserted through the opening into the hollow part of the column 110, and then the bolts are tightened. This method can hide the bolts and improve the appearance of the product.

[0135] Reference Fig.17 In order to further facilitate the connection between the column 110 and the beam 120, a pre-connector 1103 is added at the screw connection between the ends of the column 110 and the beam 120, and the pre-connector 1103 forms a clearance fit with the pre-connector cavity 1222 on the beam 120 (refer to Fig. 20 ), one advantage is that the pre-connector 1103 can support the beam 120, and the second advantage is that the cooperation between the pre-connector 1103 and the pre-connector cavity 1222 also plays an anti-foolproof role, which is convenient for the pre-connection between the beam 120 and the column 110, and is convenient for subsequent support screwdriver operation.

[0136] Furthermore, in order to enhance the connection stability between the crossbeam 120 and the column 110, a reinforcing member 111, such as an angle iron, may be added inside the column 110 to enhance the connection stability between the two. For the opening position at the upper end of the column 110, after the column 110 and the crossbeam 120 are installed, the end cover 112 may be used to seal the opening at the upper end of the column 110 to prevent rainwater from directly entering the column 110.

[0137] In the existing roof drainage method, rainwater usually flows out directly from the roof through the side after falling on the louver roof. This will cause the water flow around the louver roof to be relatively dense. In some products with exterior walls, such as viewing sheds, the exterior wall sides of the products are drenched by rainwater from the roof, and pollutants such as mud and leaves in the rainwater are easily retained, causing pollution to the exterior walls of products such as viewing sheds. In order to overcome the above-mentioned defects, the present embodiment adopts a hollow column 110 to be connected with the drainage channel 130, and the column 110 is used to discharge the water in a centralized manner. Specifically: a water outlet is provided at the lower end or side of the hollow column 110, and the upper end of the side of the column 110 is connected to the drainage channel 130 through a guide member 131. The rainwater collected in the drainage channel 130 enters the column 110 through the guide member 131 and is discharged in a centralized manner through the water outlet of the column 110. In this way, the rainwater does not need to be directly discharged through the side of the roof, and the pollution of the exterior wall of the viewing shed will not occur.

[0138] In this embodiment, refer to Fig.17 and 18 In the case where the shape of the column 110 is a rectangular parallelepiped, the shape of the side of the guide member 131 that adapts to the side of the column 110 is an L-shaped notch. The cross-section of the entire guide member 131 is an L-shaped structure, which is hollow inside, and the L-shaped notch part is stuck on the adjacent two sides of the column 110.

[0139] In this embodiment, the nozzle assembly includes a guide nozzle and a guide port, the guide nozzle includes a first nozzle 1302 and a second nozzle 1310, and the guide port includes a first guide port 1312 and a second guide port 1101. Specifically, the guide member 131 is provided with a second nozzle 1310 on one side of the contact surface of the column 110, and the guide member 131 sets the side of the second nozzle 1310 to be in an open state, and the side of the column 110 is provided with a second guide port 1101 corresponding to the position of the second nozzle 1310, and the guide member 131 is inserted into the second guide port 1101 through the second nozzle 1310, and then In order to achieve communication between the interior of the guide member 131 and the interior of the hollow column 110, a first guide port 1312 is provided at the other two sides of the guide member 131 corresponding to the positions of the drainage channel 130, and a first plug 1302 that can be inserted into the first guide port 1312 is provided at the end of the drainage channel 130. In this way, through the above arrangement, the water flow in the drainage channel 130 can be inserted into the first guide port 1312 through the first plug 1302, and then the water flow in the drainage channel 130 can be guided into the column 110 through the guide member 131, and discharged centrally through the water outlet at the lower end of the column 110.

[0140] Based on the above embodiment, the above-mentioned second plug 1310 is arranged on the guide member 131, and the second guide port 1101 is arranged on the column 110. Of course, the second plug 1310 connected to the interior of the column 110 can also be arranged on the column 110, and the second guide port 1101 can be arranged on the guide member 131. This can also achieve the above-mentioned effect. It can be seen that the setting positions of the first plug 1302 and the first guide port 1312 can also be interchanged on the drainage channel 130 and the column 110.

[0141] Furthermore, in order to prevent impurities in the drainage channel 130 from entering the column 110 and affecting the normal drainage of the column 110, an adjusting member is provided on the guide member 131, and the adjusting member includes a filter gate 1311 provided at an open position of the guide member 131 close to the second plug 1310. By providing a slide groove on the inner wall of the guide member 131, the filter gate 1311 is movably inserted in the slide groove to achieve a detachable connection of the filter gate 1311. A plurality of through holes are provided inside the filter gate 1311, through which water can flow into the column 110, while impurities will be throttled by the filter gate 1311 in the drainage channel 130, and personnel can clean the impurities in the easily disassembled drainage channel 130.

[0142] In the above embodiment, when the filter gates 1311 are all provided with through holes, rainwater will be input into the four columns 110 through the ends of the drainage channel 130. At this time, the four columns 110 can drain water simultaneously. Furthermore, the regulating member can also be a sealing plate that does not allow rainwater to pass through. It can be imagined that by setting sealing plates at different positions, that is, the sealing plates close the open position of the water flow in the drainage channel 130 entering the guide member 131, it is possible to limit the rainwater in the drainage channel 130 from entering the columns 110. Then, by utilizing the above characteristics, the water in the drainage channel 130 can be discharged centrally through specific columns 110. The corresponding inner walls of the columns 110 used for drainage can be coated with a waterproof and anti-corrosion coating, or the columns 110 used for drainage can be made of materials that are resistant to rust and have better waterproof properties, which can effectively reduce production costs. At the same time, through the above characteristics, the possibility of water seepage around the bottom of the viewing shed or other sheds due to the simultaneous drainage of the four columns 110 is avoided, which effectively improves the practicality and waterproofness of the viewing shed.

[0143] Based on the above embodiment, in order to facilitate the disassembly and assembly of the louver 300 on the long beam 120a, the pin 330 at the end of the louver 300 is set to be retractable. Specifically, at least one end of the main body 3000 of the louver 300 is provided with a sliding hole for the pin 330 to slide along the inside thereof, and the pin 330 can slide in the sliding hole. One end of the pin 330 located in the sliding hole is elastically connected to the end of the sliding hole through an elastic member 331, which can touch the pin 330 and extend from the movable part, so as to facilitate the connection between the louver 300 and the pin hole of the axial hole 122a of the long beam 120a.

[0144] In this embodiment, the elastic member 331 can be a material with an elastic compression space such as a spring. Its function is that when the louver 300 is installed between the two long beams 120a, the spring is compressed by squeezing the latch 330, and the spring is compressed, allowing the latch 330 to enter the sliding hole. When the latches 330 at both ends of the main body 3000 are aligned with the axial holes 122a opened on the two long beams 120a, the latch 330 is pushed into the axial hole 122a under the elastic reset action of the spring, thereby realizing the rotational connection between the louver 300 and the axial hole 122a on the long beam 120a.

[0145] Based on the above embodiment, in this embodiment, the air conditioner 200 is installed between the short beam 120b and the side of the louver roof, and matching grooves are provided on both sides of the air conditioner 200. One side of the air conditioner 200 is engaged with the second clamping head 121b provided on the beam cover 121 through the matching groove, so that one side of the air conditioner 200 is clamped with the short beam 120b. Based on the above, a second clamping head 121b can also be provided on the side of the louver blade 300 adjacent to the air conditioner 200, so as to realize the clamping between the louver blade 300 and the air conditioner 200. Through the above scheme, it is convenient for the air conditioner 200 to be clamped with the short beam 120b. 0b, and at the same time, due to the deadweight of the air conditioner 200, the second clamping head 121b of the beam cover 121 always maintains a vertical downward force, so that the clamping connection between the first clamping head 121a on the other side of the beam cover 121 and the first clamping groove 1223 of the side frame 1201 is more stable. The convenient installation between the air conditioner 200 and the beam cover 121 also provides a stabilizing effect for the connection stability between the beam cover 121 and the side frame 1201, which facilitates the installation of the air conditioner 200 and improves the installation stability of the beam cover 121 on the side frame 1201, killing two birds with one stone.

[0146] Based on the above embodiment, in order to enhance the installation stability of the air conditioner 200, a reinforcing seat can also be added between the two ends of the air conditioner 200 and the long beam 120a, and the existing bolt fastening method can be used to lock the two ends of the air conditioner 200 and the long beam 120a to improve the stability of the air conditioner 200 installed on the viewing shed.

[0147] In summary, the louver blades, louver roof and viewing shed of the embodiments of the present application can reduce dripping when turning open, thereby improving the user experience.
