Description

Technical Field

[0001] The utility model relates to the field of rainproof boards, in particular to a rainproof board with good air permeability. Background Art

[0002] Since some old residential areas do not have elevators installed, and it is very inconvenient for people living in high-rise buildings, some old residential areas will install elevators outside the buildings to increase the convenience of transportation. Before installing the elevator, it is necessary to install an elevator shaft to ensure that the elevator can be used normally. When installing the existing elevator shaft, it is necessary to install flashing plates on the outer wall to prevent rain and other water damage. During the installation process of the current flashing plates, the position between the flashing plates and the wall and between two adjacent flashing plates is generally fixed by gluing. However, the effect of gluing will vary with the operator, and after a long period of wind and rain, the gluing position will also become debonded. Therefore, the long-term waterproof effect of the flashing plates cannot be guaranteed, which leads to water entering the elevator shaft. To address this issue, a prior art Chinese patent, published under the publication number CN216076123U, discloses a rain shield. This design employs a spliced drip panel, which is assembled from several panels and then installed in their proper locations. While this installation method provides basic rain protection, the spliced drip panels are too tightly sealed. Because the upper and lower panels lack any ventilation holes, the air inside the elevator shaft cannot effectively exchange with the outside world. While this sealing may initially appear to be waterproof, it can adversely affect elevator operation and the shaft environment over time.

[0003] Specific disadvantages include: 1. The temperature inside a sealed elevator shaft is easily affected by the external environment and fluctuates, which can damage the elevator's mechanical components and electronic equipment. Lack of ventilation can cause humidity to accumulate in the shaft, increasing the risk of corrosion and short circuits in elevator components.

[0004] 2. When the elevator is running, air pressure changes will occur. The sealed shaft may not be able to effectively balance these changes, thus affecting the stability of the elevator and the comfort of passengers.

[0005] 3. Lack of ventilation will lead to a decrease in air quality in the shaft, which may cause odor and mold, posing a threat to the health of passengers.

[0006] 4. When a sealed well needs to be repaired or inspected, the lack of air circulation may increase the difficulty and danger of the work. Summary of the Invention

[0007] To solve the above problems, the utility model provides a rain shield with good air permeability, and a plurality of air holes are provided on the bottom surface of the bent portion. These air holes solve the problem of stuffiness in the elevator shaft caused by the lack of air permeability structure of the previous rain shield.

[0008] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rain shield with good air permeability, comprising a rain shield and at least one bent portion provided on the rain shield, a mounting groove being provided at the lower end of the rain shield, and a mounting plug being provided at the upper end of the rain shield; when two adjacent rain shields are spliced together, the mounting plug in one of the rain shields is inserted into the mounting groove in the other rain shield, and a plurality of air holes are provided at the bottom of the bent portion.

[0009] Furthermore, the multiple bending portions are connected in sequence from top to bottom, and each bending portion includes a first bending surface and a second bending surface, wherein the side projections of the first bending surface and the second bending surface form a bending angle, and the bending angle is less than 90°; the first bending surface is the inclined surface of the bending angle, and the second bending surface is the bottom surface of the bending angle; wherein a plurality of air holes are distributed on the surface of the second bending surface.

[0010] Furthermore, the connection between the first bending surface and the second bending surface is an arc structure.

[0011] Furthermore, the mounting insert and the mounting groove are located on the same side of the flashing plate.

[0012] Furthermore, the mounting groove is an inverted U-shaped groove.

[0013] Furthermore, an extended mounting plate is provided at the end of the mounting groove, and the horizontal plane of the end of the extended mounting plate is lower than the second bending surface at the lowest position, and the mounting insert moves from the extended mounting plate to the inside of the mounting groove.

[0014] Furthermore, the multiple bending portions are arranged on the same axis.

[0015] Furthermore, the bolts are passed through the mounting insert and the extended mounting plate to achieve the assembly of the two.

[0016] The beneficial effects of the present invention are as follows: when installing the rain shields, the present invention inserts the installation plug of one of the two adjacent rain shields into the installation groove of the other rain shield, so that when the two adjacent rain shields are spliced and installed, the two adjacent rain shields can be limitedly connected by the buckling between the installation plug and the installation groove, and because the installation plug is buckled into the installation groove, the connection position between the installation plug and the installation groove will not be directly exposed to wind and rain, which increases the reliability of the connection between the installation plug and the installation groove. At the same time, since the two adjacent rain shields are connected in a plug-in manner, there is no need to use glue to fix the rain shield, which increases the simplicity of installing the rain shield; and in the process of using the rain shield, due to the bent part on the rain shield, rainwater will flow to the elevator shaft and the outside of the rain shield under the guidance of the bent part, ensuring that the elevator shaft and the inside of the rain shield will not be flooded, thereby increasing the waterproof effect of the rain shield.

[0017] Furthermore, several ventilation holes are located on the bottom of the curved section. These holes address the problem of stuffiness in the elevator shaft caused by the lack of ventilation in previous flashings. First, the holes allow air to circulate freely inside and outside the flashing, creating a natural airflow path that helps dissipate accumulated heat and moisture in the elevator shaft, effectively reducing the temperature and humidity inside the elevator shaft and creating a more suitable operating environment. Second, the holes promote air circulation, helping to prevent the growth of microorganisms such as mold and bacteria on the back of the flashing and within the elevator shaft, thereby improving the sanitation of the elevator shaft.

[0022] See also Figure 1-3 As shown, the utility model relates to a rain shield with good air permeability, comprising a rain shield, at least one bent portion 2 provided on the rain shield, a mounting groove 3 provided at the lower end of the rain shield, and a mounting insert 1 provided at the upper end of the rain shield; when two adjacent rain shields are spliced together, the mounting insert 1 in one rain shield is inserted into the mounting groove 3 in the other rain shield; and a plurality of air holes 221 are provided at the bottom of the bent portion 2.

[0023] When installing the rain shield of the utility model, the installation plug 1 of one of the rain shields of the two adjacent rain shields is inserted into the installation groove 3 of the other rain shield, so that when the adjacent rain shields are spliced and installed, the two adjacent rain shields can be limitedly connected by the buckling between the installation plug 1 and the installation groove 3. Moreover, since the installation plug 1 is buckled into the installation groove 3, the position where the installation plug 1 and the installation groove 3 are connected will not be directly exposed to wind and rain, thereby increasing the reliability of the connection between the installation plug 1 and the installation groove 3. At the same time, since the plug-in connection method is adopted between the two adjacent rain shields, there is no need to use glue to fix the rain shield, thereby increasing the simplicity of installation of the rain shield. During the use of the rain shield, due to the bent part 2 on the rain shield, rainwater will flow to the elevator shaft and the outside of the rain shield under the guidance of the bent part 2, ensuring that the elevator shaft and the inside of the rain shield will not be flooded, thereby increasing the waterproof effect of the rain shield.

[0024] Furthermore, the bottom surface of the bent portion 2 is provided with a number of ventilation holes 221. These holes 221 address the problem of stuffiness within the elevator shaft caused by the lack of ventilation in conventional flashings. First, the holes 221 allow air to circulate freely within and outside the flashing, creating a natural airflow path that helps dissipate heat and moisture accumulated within the elevator shaft, effectively reducing the temperature and humidity within the elevator shaft and creating a more suitable operating environment. Second, the holes 221 promote air circulation, helping to prevent the growth of microorganisms such as mold and bacteria on the back of the flashing and within the elevator shaft, thereby improving the sanitation of the elevator shaft.

[0025] Furthermore, the multiple bending portions 2 are connected in sequence from top to bottom, and each bending portion 2 includes a first bending surface 21 and a second bending surface 22, wherein the side projections of the first bending surface 21 and the second bending surface 22 form a bending angle, and the bending angle is less than 90°; the first bending surface 21 is the inclined surface of the bending angle, and the second bending surface 22 is the bottom surface of the bending angle; wherein a plurality of air holes 221 are distributed on the surface of the second bending surface 22.

[0026] By connecting a plurality of bending portions 2 in sequence from top to bottom, and each bending portion 2 is designed to include a first bending surface 21 (slant) and a second bending surface 22 (bottom surface), wherein the bending angle is less than 90°, such a design is conducive to the rapid sliding of rainwater. The first bending surface 21, as a slope, can effectively reduce the retention time of rainwater on the rainproof plate, prompting rainwater to quickly flow downward or drip, reducing the possibility of water accumulation, thereby improving the drainage efficiency of the rainproof plate. The second bending surface 22, as the bottom surface of the bending angle, is designed to be flatter and slightly inward-inclined compared to the slope. Such a structure helps prevent rainwater from flowing back or penetrating into the interior of the rainproof plate, especially the area where the air vents 221 are located. This design ensures that the air vents 221, while performing their ventilation function, will not cause damage to the internal structure or loss of function due to direct impact or penetration of rainwater, thereby maintaining the overall stability and durability of the rainproof plate.

[0027] The continuous arrangement of multiple bending portions 2 and the design of the bending angles enhance the structural strength and stability of the flashing, allowing the flashing to maintain good form and functionality when subjected to external forces such as wind and rain, reducing the need for repair and replacement due to deformation or damage.

[0028] Furthermore, the connection between the first curved surface 21 and the second curved surface 22 is an arc structure 4. The arc structure 4 is more smooth and harmonious visually, reducing the abruptness caused by right angles and sharp angles, making the overall appearance of the flashing more beautiful and improving the overall visual effect of the building. Moreover, the arc design can effectively disperse and alleviate the concentrated stress generated by external forces (such as wind, rain, installation stress, etc.) during installation and use, avoiding problems such as cracks and breakages that are prone to occur at right-angle connections, thereby improving the structural strength and durability of the flashing. At the same time, the arc design reduces sharp corners, reduces the risk of injury to personnel during installation, maintenance or daily contact, and improves the safety and user-friendliness of the product.

[0029] Furthermore, the mounting insert 1 and the mounting groove 3 are located on the same side of the flashing plate, thereby ensuring that a plurality of flashing plates are spliced to form a dripping structure, and the inclined surface of the dripping structure is arranged in one direction, thereby achieving a dripping waterproof effect.

[0030] Furthermore, the mounting groove 3 is an inverted U-shaped groove. Specifically, in this solution, the mounting groove 3 is an inverted U-shaped structure. When installing two adjacent flashing boards, after the mounting plug 1 is inserted into the mounting groove 3, the two sides of the inverted U-shaped structure will wrap and protect the mounting plug 1, so that the mounting plug 1 will not shake freely in the mounting groove 3. At the same time, the upper arc position of the inverted U-shaped structure will limit the mounting plug 1 to ensure the relative position between the two adjacent flashing boards is stable.

[0031] Furthermore, an extended mounting plate 31 is provided at the end of the mounting groove 3. The end of the extended mounting plate 31 is located at a lower level than the second curved surface 22 at the lowest position. The mounting insert 1 moves from the extended mounting plate 31 into the mounting groove 3. The extended mounting plate 31 provides a smooth guide path for the mounting insert 1, allowing the installer to easily slide the mounting insert 1 from the extended mounting plate 31 into the mounting groove 3 when splicing the flashing. This design reduces installation difficulty, which is particularly important when installing at high altitude or in locations that are difficult to observe directly.

[0032] Furthermore, the multiple bends 2 are arranged along the same axis. Furthermore, the multiple bends 2 are arranged along the same axis to reduce the footprint of the flashlight. The fact that the bends 2 are located along the same axis means that rainwater will flow in an orderly manner along this axis when dripping, reducing the possibility of rainwater spreading laterally on the surface of the flashlight, making drainage more concentrated and efficient. This helps to quickly direct rainwater to the intended area and reduce the risk of water accumulation. Specifically, after the flashlight is installed, the vertical projection area of each bend 2 relative to the ground is the same.

[0033] Specifically, when installing the rain shield, after connecting and fixing the two adjacent rain shields through the mounting plug 1 and the mounting groove 3, the bolts are passed through the mounting plug 1 and the mounting groove 3 to fix them to the corresponding insulation board (or other structure), so that the position of each rain shield can be positioned by the insulation board (or other structure), and the insulation board (or other structure) is positioned toward one side of the elevator. At this time, since the insulation board (or other structure) and the bending part 2 are respectively located on both sides of the main body, the bending part 2 is set in the direction away from the elevator, so that the bending part 2 blocks external rainwater, and the insulation board (or other structure) fixes the rain shield on the inside.

[0034] Preferably, the bolts are inserted through the mounting insert 1 and the extended mounting plate 31 before being connected to the insulation board (or other structure). The design of the extended mounting plate 31 not only provides a smooth guide path for the mounting insert 1 but also facilitates the insertion and securing of the bolts. This makes the installation process simpler and faster, reduces installation difficulty and labor intensity, and improves installation efficiency.

[0035] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
