Description

Technical Field

[0001] The utility model relates to a rainproof shutter structure. Background Art

[0002] In construction projects, rain shutters are a common structural component used in the outdoor unit of air conditioners on exterior walls. Their main function is to achieve ventilation and heat dissipation while taking into account the aesthetic design of the facade. Traditional rain shutters are usually composed of vertical rectangular tubes, horizontal rectangular tubes and louvers, which are fixed to the outer frame of the civil wall by expansion bolts. This type of structure has some objective disadvantages in practical applications, especially when the outer frame and rain shutters are fixed by screws. Too tight screw assembly can easily cause deformation of the outer frame, thereby affecting its structural stability and aesthetic effect. Utility Model Content

[0003] The utility model aims to provide a rainproof louver structure which overcomes the deformation problem of traditional rainproof louvers caused by over-tightening of screws and improves the convenience of installation and reliability of use.

[0004] The purpose of the utility model is achieved in this way:

[0005] A rainproof shutter structure, comprising a frame, shutters and a lock, wherein the frame is fixed to a main structure, a hole is opened in the frame at a position corresponding to an outdoor unit of an external wall air conditioner, the shutter is placed in the hole, the upper part of the shutter is hinged in the frame, and the shutter rotates with the hinge as the rotation center to open or close the outdoor unit of the external wall air conditioner;

[0006] The lock comprises a lock pin, a first seat body and a second seat body, wherein the first seat body is fixed at the lower part of the blind, the lock pin is movably arranged in the first seat body, the second seat body is fixed on the frame, and a lock hole is opened in the second seat body corresponding to the position of the lock pin;

[0007] When the shutter is rotated to close the outdoor unit of the external wall air conditioner, the lock pin is inserted into the lock hole and the shutter is in a locked state.

[0008] Prevent outer frame deformation: By adopting a hinged design, the louver blades do not need to be fixed by over-tightening screws, avoiding the problem of outer frame deformation caused by over-tightening of traditional screws, and ensuring the stability and durability of the overall structure.

[0009] Flexible opening and closing: The upper part of the shutter is hinged in the frame, and the hinge is used as the rotation center. The outdoor unit of the exterior wall air conditioner can be flexibly opened or closed. It is easy to use and simple to operate.

[0010] Safety locking: A locking system is designed. When the shutters are closed, the locking pin is inserted into the keyhole to ensure that the shutters will not be easily opened due to external force when closed, providing a safe locking function and enhancing the protection performance.

[0011] Easy installation: The structure is simple in design, connected by frame and hinges, without complicated installation procedures, which reduces the construction difficulty and improves the installation efficiency.

[0012] Enhanced aesthetics: The screw connection between the outer frame and the louver is eliminated, avoiding the situation where the screws are exposed and affecting the appearance, and improving the overall aesthetics of the building facade.

[0013] Easy maintenance: Since the louvers can be opened flexibly, daily inspection and maintenance of the air-conditioning outdoor unit is convenient, which improves the convenience of use and the operability of maintenance.

[0014] The purpose of the utility model can also be solved by the following technical measures:

[0015] Furthermore, the louver comprises an outer frame and louver blades, and the louver blades are arranged in the outer frame at intervals.

[0016] Furthermore, the outer frame includes zinc steel rectangular tubes, and the zinc steel rectangular tubes surround the outer frame.

[0017] Furthermore, the outer frame also includes corner wraps and blind rivets, the corner wraps are provided at the connection between the zinc-steel rectangular tubes, and the blind rivets pass through the corner wraps to lock the corresponding zinc-steel rectangular tubes.

[0018] Furthermore, it also includes expansion bolts. The zinc steel rectangular tube corresponding to the upper part of the outer frame is provided with a socket. The expansion bolts pass through the sockets and the frame is locked to the main structure. The shutters rotate with the expansion bolts as the rotation center.

[0019] Enhanced fixing strength: Expansion bolts firmly fix the frame to the main structure through the sockets, providing stronger fixing strength and stability, ensuring the reliability of the blinds during long-term use.

[0020] Flexible opening and closing: The upper part of the shutter rotates with the expansion bolt as the rotation center, which can flexibly open or close the outdoor unit of the exterior wall air conditioner. It is simple to operate and easy to use.

[0021] Convenient installation: The design of the expansion bolt simplifies the installation process, eliminates the need for complicated installation procedures, improves construction efficiency, and at the same time provides a firm installation effect and reduces construction difficulty.

[0022] The beneficial effects of the utility model are as follows:

[0023] The utility model adopts a hinged design, so the louver does not need to be fixed by over-tightening screws, avoiding the problem of deformation of the outer frame caused by over-tightening of traditional screws, ensuring the stability and durability of the overall structure. Since the louver can be opened flexibly, daily inspection and maintenance of the air-conditioning outdoor unit are convenient, thereby improving the convenience of use and the operability of maintenance.

[0024] The utility model is designed with a lock system. When the shutter is closed, the lock pin is inserted into the lock hole to ensure that the shutter blades will not be easily opened due to external force in the closed state, thereby providing a safe locking function and enhancing the protection performance.

[0025] The utility model adopts zinc steel rectangular tube for the outer frame, which has excellent corrosion resistance and strength. The use of corner wraps and blind rivets further enhances the stability of the structure and ensures the long-term service life of the shutters.

[0026] In the utility model, the outer frame surrounded by the zinc steel rectangular tube is locked by corner wrapping and core-pulling rivets, thereby ensuring the stability and strength of the overall frame and avoiding the risks of loosening and deformation.

[0027] The utility model has an upper part of a shutter hinged in a frame, and uses an expansion bolt as a rotation center, so that the outdoor unit of the external wall air conditioner can be flexibly opened or closed, and is convenient to use and simple to operate.
