Description

Technical Field

[0001] The utility model relates to the technical field of inflatable membranes, in particular to a high-pressure resistant inflatable membrane. Background Art

[0002] There are three types of inflatable membrane structures: single-layer, double-layer, and air-ribbed. Inflatable membrane structures generally require long-term uninterrupted energy supply. Single-layer inflatable membrane structures in low-arch and large-span buildings must be closed spaces and maintain a certain indoor and outdoor air pressure difference.

[0003] Although the existing inflatable membrane has a certain degree of light transmittance during use, it cannot fully provide light for buildings with high lighting requirements. At the same time, since it does not have a pressure relief mechanism inside, it is easy to cause the inflatable membrane to be damaged when branches are blown or heavy objects fall in bad weather, thereby reducing the pressure resistance of the existing inflatable membrane. For this reason, we proposed a high-pressure resistant inflatable membrane. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a high-pressure resistant inflatable membrane with the advantages of high transparency, high brightness and high pressure resistance, which solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a high-pressure resistant inflatable membrane comprises an outer membrane, the top of the outer membrane is fixedly equipped with a light-transmitting film 1, the inner wall of the outer membrane is provided with an inner membrane, the outer wall of the inner membrane is fixedly equipped with a light-transmitting film 2, the top of the light-transmitting film 2 is fixedly equipped with a sleeve, the inner wall of the sleeve is slidably sleeved with a sliding rod, the inner wall of the sleeve is provided with a limiting rod, the top of the limiting rod is fixedly equipped with a limiting ring, the outer wall of the limiting rod is sleeved with a spring, the sliding rod is located at one end of the inner wall of the sleeve and is fixedly equipped with a limiting block, the outer wall of the sleeve is provided with a vent hole, and the middle parts of the limiting block and the sliding rod are both provided with movable grooves.

[0006] As a preferred technical solution of the present invention: the number of the vent holes is two, and the two vent holes are evenly distributed along the outer wall of the sleeve.

[0007] As an optimal technical solution of the present invention: the inner wall of the outer membrane is filled with high-pressure air, and when the top of the limit block contacts the top of the inner wall of the sleeve, the sleeve and the interior of the outer membrane are isolated, otherwise the two are connected.

[0008] As a preferred technical solution of the present invention: the light-transmitting film 1 and the light-transmitting film 2 are both made of acrylonitrile / butadiene / styrene copolymer plates, and the outer film and the inner film are both made of E-type (ETFE) film material.

[0009] As a preferred technical solution of the present invention: the number of the sleeves is several, and the sleeves are evenly distributed along the outer wall of the second light-transmitting film.

[0010] As a preferred technical solution of the present invention: the outer wall of the limiting ring is slidably connected to the inner wall of the movable groove, and the limiting ring and the limiting rod are both made of galvanized iron metal.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The high-pressure resistant inflatable membrane, through the outer membrane, transparent membrane 1, inner membrane, and transparent membrane 2 structures, makes it possible for the inflatable membrane to be inflated. Since the materials of the four membranes are all made of high light transmittance, the sunlight will not be excessively blocked when it is irradiated, thereby ensuring the light transmittance of the inflatable membrane. In addition, the inflatable membrane has the characteristics of high brightness and high transmittance when in use, ensuring sufficient light supply.

[0013] 2. The high-pressure resistant inflatable membrane has a sleeve, spring, limit block, limit ring, movable groove, limit rod, vent and slide rod structure. When branches and heavy objects fall due to bad weather, the slide rod drives the limit block to move downward and compresses the spring, thereby exposing the vent and allowing high-pressure air to enter the sleeve, avoiding damage to the inflatable membrane and improving the pressure resistance of the inflatable membrane.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 , a high-pressure resistant inflatable membrane includes an outer membrane 1, the top of the outer membrane 1 is fixedly equipped with a transparent film 2, the inner wall of the outer membrane 1 is provided with an inner membrane 3, the outer wall of the inner membrane 3 is fixedly equipped with a transparent film 2 4, the top of the transparent film 2 4 is fixedly equipped with a sleeve 5, the inner wall of the sleeve 5 is slidably sleeved with a slide rod 6, the inner wall of the sleeve 5 is provided with a limit rod 8, the top of the limit rod 8 is fixedly equipped with a limit ring 12, the outer wall of the limit rod 8 is sleeved with a spring 9, the slide rod 6 is located at one end of the inner wall of the sleeve 5 and is fixedly equipped with a limit block 10, the outer wall of the sleeve 5 is provided with a vent 7, and the middle of the limit block 10 and the slide rod 6 are provided with a movable groove 11.

[0021] In the above structure, through the arrangement of the outer film 1, the light-transmitting film 1 2, the inner film 3, and the light-transmitting film 2 4, when the outer film 1 and the inner film 3 are inflated, the materials of the outer film 1 and the inner film 3 themselves have high light transmittance, and the materials of the light-transmitting film 1 2 and the light-transmitting film 2 4 also have high light transmittance characteristics, thereby ensuring that the light transmittance of the inflatable film is minimized after it is inflated, thereby making the inflatable film have the characteristics of high transmittance and high brightness.

[0022] In a preferred embodiment, the number of the vent holes 7 is two, and the two vent holes 7 are evenly distributed along the outer wall of the sleeve 5 .

[0023] In the above structure, through the two vent holes 7, when the surface of the outer membrane 1 is hit by a heavy object, the impact force will cause the outer membrane 1 to sag inward, thereby squeezing the slide rod 6 and allowing the limit block 10 to compress the spring 9. After the vent holes 7 are exposed, the high-pressure air between the outer membrane 1 and the inner membrane 3 will enter the sleeve 5 through the vent holes 7, thereby reducing the probability of damage to the inflatable membrane under high pressure, thereby improving the pressure resistance of the inflatable membrane.

[0024] In a preferred embodiment, the inner wall of the outer membrane 1 is filled with high-pressure air. When the top of the limit block 10 contacts the top of the inner wall of the sleeve 5, the sleeve 5 and the interior of the outer membrane 1 are isolated, otherwise they are connected.

[0025] In the above structure, the limiting effect of the limiting ring 12 on the slide rod 6 and the retractable characteristic of the slide rod 6 are used to ensure that the inflatable membrane can maintain its original shape even in windy and rainy weather. The transfer of high-pressure air also allows the interior of the sleeve 5 to buffer the outer membrane 1.

[0026] In a preferred embodiment, the light-transmitting film 1 2 and the light-transmitting film 2 4 are both made of acrylonitrile / butadiene / styrene copolymer sheets, and the outer film 1 and the inner film 3 are both made of E-type (ETFE) film material.

[0027] In the above structure, the acrylonitrile / butadiene / styrene copolymer board and the E-type (ETFE) membrane material both have high light transmittance, thereby ensuring that the inflatable membrane minimizes the degree of light shielding during use, thereby ensuring that the inflatable membrane can be used in agriculture and construction, thereby expanding the scope of use of the inflatable membrane.

[0028] In a preferred embodiment, there are a plurality of sleeves 5 , and the sleeves 5 are evenly distributed along the outer wall of the second light-transmitting film 4 .

[0029] In the above structure, by setting up several sleeve 5 structures, the interlayer between the outer membrane 1 and the inner membrane 3 can be fully protected to avoid the situation where the inflatable membrane as a whole is damaged and cannot be used normally, thereby ensuring the service life of the inflatable membrane and improving the practicality of the inflatable membrane.

[0030] In a preferred embodiment, the outer wall of the limiting ring 12 is slidably connected to the inner wall of the movable groove 11, and the limiting ring 12 and the limiting rod 8 are both made of galvanized iron metal.

[0031] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the limit rod 8 and the limit ring 12 during operation, thereby extending the service life of both. At the same time, the galvanized iron metal also has the characteristic of low cost, thereby reducing the production cost of the inflatable membrane.

[0032] Working principle: First, when the user inflates, the interlayer between the outer membrane 1 and the inner membrane 3 will be filled with high-pressure air, causing the inflatable membrane to bulge. Due to the characteristics of the material, the inside of the inflatable membrane can also be fully exposed to light and sunlight, thereby ensuring the light transmittance of the inflatable membrane. When heavy objects are blown onto the inflatable membrane in bad weather, the outer membrane 1 will sink inward and the limit block 10 will compress the spring 9, allowing the high-pressure air to enter the sleeve 5 through the vent 7, thereby transferring the high-pressure air and reducing the chance of damage to the inflatable membrane, thereby improving the pressure resistance of the inflatable membrane.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
