Description

Technical Field

[0001] The invention belongs to the technical field of shutters, and in particular relates to a manual waterproof shutter for a vehicle-mounted shelter. Background Art

[0002] Military vehicle-mounted shelters must have excellent ventilation and waterproofing. This is especially true for the sloped design of the shelter's ventilation windows, which must balance ventilation and waterproofing requirements in extreme environments. Existing shutters, however, lack the waterproofing, adaptability, and ease of operation required to meet military requirements in these conditions.

[0003] Chinese invention patent publication number CN115653468A discloses a bamboo and wood venetian blind blade adsorption mechanism, which achieves a waterproof function by adjusting the overall inclination angle of several blades and a fixing box through the mutual cooperation of an adjustment component and a limit component; Chinese invention patent publication number CN118358693A discloses a pneumatic venetian blind for ships with an anti-impact mechanism, which is equipped with a flexible sealing rod to seal the gap between two adjacent blades; Chinese utility model patent publication number CN210396569U discloses a rainproof and ventilated venetian blind and a square cabin power station for a square cabin power station, which can be installed on a horizontal top or an inclined surface.

[0004] The present invention systematically provides a shutter structure solution to solve the above problems by fully considering the installation angle, innovating and optimizing the sealing and linkage mechanism design. Summary of the Invention

DETAILED DESCRIPTION

[0041] The present invention is further described below with reference to the accompanying drawings and specific embodiments. However, it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above technical ideas of the present invention, various modifications, substitutions and changes made according to common technical knowledge and customary means in the field are included in the scope of the present invention.

[0042] Overall structure, the relationship between the shutter appearance and structure is as follows Figure 1-Figure 3 , Figures 13-18 As shown, it consists of a blade assembly 10, a frame 20, a manual operating mechanism 30, a blade linkage synchronization mechanism 40, a sealing system, a dust screen 1, a rain shield 2, and a rotating shaft 3. The overall outline is designed to be a rectangular structure that fits the installation surface of the shelter. The middle blade group is higher than the edge of the shutter mounting flange, and the bottom is provided with drainage slots to facilitate the rapid discharge of rainwater.

[0043] The blade assembly 10, such as Figure 4 and Figure 5As shown, the blade assembly 10 is composed of four parts: a rivet 11, a tower-shaped sealing strip 12, a blade 13, and an L-shaped connecting piece 14. The blade assembly adopts a structural waterproof design with overlapping structures, and the blade assemblies are arranged 50mm apart to effectively prevent rainwater from penetrating. The blade 13 is made of 6061-T6 aluminum alloy, the blade cross-section adopts a barbed structure, and the blade surface is sprayed with a polyurethane waterproof coating. The L-shaped connecting piece 14 is made of stainless steel and is laser cut and bent. One end of the L-shaped connecting piece 14 is fixed to one side of the blade by two rivets, and the other end is screwed to the blade linkage synchronization mechanism 40; the tower-shaped sealing strip 12 is made of silicone rubber, with a single-sided adhesive backing, and is tightly attached to one side of the groove of the blade 13.

[0044] Frame 20, such as Figure 6 As shown, the frame 20 is designed as a rectangular structure made of 6061-T6 aluminum alloy. It is welded together from four components: the left frame 21, the upper frame 22, the right frame 23, and the lower frame 24. The frame thickness is suitable for a 50mm square bulkhead. The outer flange is fixed to the bulkhead using a combination of screws and waterproof structural adhesive. The frame has two parallel U-shaped grooves on the inside. The outer U-shaped grooves serve as drainage channels, cooperating with the straight slots in the lower frame 24 to guide rainwater outward. The inner U-shaped grooves serve as sealing strip slots for inserting waterproof sealing strips to seal against rainwater ingress. Frame 20 has symmetrically threaded holes on both sides. Each threaded hole is fitted with a stainless steel screw, one end of which engages the corresponding circular hole in the blade assembly 10. The screws serve as the rotation axis 2 of the blade assembly 10, allowing the blade assembly 10 to open and close relative to the frame 20. The manual operating mechanism 30 can adjust the opening and closing angle between 0° and 90°. Multiple threaded holes are evenly distributed on the back of the frame 20 to facilitate the installation of the dust screen 1.

[0045] Manual operating mechanism 30, such as Figure 7-Figure 9 As shown, the manual operating mechanism 30 adopts a worm-gear manual rotation structure to achieve precise adjustment of the angle of the blinds blades, and at the same time has good self-locking performance to prevent the blades from rotating by themselves due to external forces. The manual operating mechanism (30) is composed of a worm gear shaft 31, a housing 32, a fixing plate 33, a plum blossom handle 34, a connecting shaft 35, a worm 36, a support plate 37, and a fastening screw 38. The manual operating mechanism 30 is assembled on the lower left side of the blinds frame 20 by screwing the fixing plate 33 and the support plate 37. The worm gear shaft 31 is connected and fixed to the blade linkage synchronization mechanism 40, and the rotational motion of the worm 36 is converted into the circular motion of the worm wheel, thereby driving the blinds blades to rotate. The plum blossom handle 34 is installed at one end of the worm 36. The meshing of the worm gear has a large transmission ratio, which achieves deceleration and force increase, making it convenient for users to operate manually.

[0046] The blade linkage synchronization mechanism 40, such as Figure 10As shown, one end of the blade linkage synchronization mechanism 40 is connected to the manual operating mechanism 30 by screwing, and the other end is connected to multiple blade assemblies 10, thereby realizing the linkage and synchronous rotation of the blinds blades. The blade linkage synchronization mechanism 40 is composed of a long connecting rod 41, a crank 42, a long axis pin 43, a short connecting rod 44, a short axis pin 45, etc. The crank 42 is fixed and screwed to the worm shaft 31, and the crank 42, the long axis pin 43 and the short connecting rod 44 are movably connected by an axis pin, forming a simple universal joint mechanism that can rotate relative to each other. The long connecting rod 41 is connected end to end with the L-shaped connecting piece 14 on the blade assembly 10 to form multiple parallelogram connecting rod groups. When the plum blossom handle 34 of the manual operating mechanism 30 is operated, one of the blade assemblies 10 will be forced to rotate synchronously, and then the remaining blades will be driven to rotate at the same angle at the same time.

[0047] Sealing system, see Figure 11 and Figure 12 The sealing system in this technical solution primarily consists of two parts: blade seals and frame seals. Three types of sealing strips, D-shaped sealing strips 51, B-shaped sealing strips 52, and tower-shaped sealing strips 12, are used for waterproof sealing. The D-shaped sealing strip 51 is positioned between the frame 20 and the topmost blade, tightly fitting the blade and frame 20. It cooperates with the rain shield to prevent water from entering the drainage groove of the frame 20 from the upper side of the blind. The B-shaped sealing strip 52 is embedded in the rectangular U-shaped groove inside the frame 20, preventing water from entering the drainage groove of the frame 20 from entering the interior of the blind.

This article uses specific examples to illustrate the structure and operating principles of the present invention. The description of the above embodiments is intended only to facilitate understanding of the method and core concept of the present invention.
