Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-7, the present utility model provides a technical solution for the upper beam sealing structure of a hollow louver:
[0027] An upper beam sealing structure of a hollow louver includes an upper beam body 1 and a glass frame 2 detachably installed at the lower part of the side wall of the upper beam body 1. Sealing grooves 11 are provided around the side wall of the upper beam body 1, and a sealing gasket 12 is fitted and installed in the inner cavity of the sealing grooves 11. A sealing assembly 3 for pressing the sealing gasket 12 is provided on the side wall of the glass frame 2. A sealing plug 4 is fixedly installed on the upper end surface of the upper beam body 1, and a protective cover 5 is also fixedly installed on the upper end surface of the upper beam body 1. A first pressure sensor 6 is fixedly installed at the top of the inner cavity of the protective cover 5, and a numerical control display screen 7 is fixedly installed in the middle of the front end surface of the upper beam body 1.
[0028] Furthermore, the cross-section of the sealing gasket 12 is in an isosceles trapezoid shape. The material of the sealing gasket 12 is nitrile rubber. The sealing gasket 12 is hollow, and a total of 4 groups of sealing gaskets 12 are provided.
[0029] Furthermore, the sealing assembly 3 includes a fixed cylinder 31 fixedly installed on the side wall of the sealing gasket 12 and a sliding column 32 slidably installed in the inner cavity of the fixed cylinder 31. A top block 33 is fixedly installed on the side of the sliding column 32 away from the fixed cylinder 31, and a tightening spring 34 is wound and installed on the side wall of the sliding column 32;
[0030] The fixed cylinder 31 is communicated with the inner cavity of the sealing gasket 12. The fixed cylinder 31 is fixedly installed on the side wall of the glass frame 2. One end of the tightening spring 34 away from the top block 33 is fixedly installed on the side wall of the glass frame 2. Several groups of the sealing assembly 3 are provided on the side wall of the glass frame 2.
[0031] It should be noted that when initially installing the entire device, first install the fixed cylinder 31 on the side wall of the glass frame 2, and then assemble the upper beam body 1 into the inner cavity of the glass frame 2. At this time, the upper beam body 1 will squeeze the sealing gasket 12, making it deflated. Finally, the sealing gasket 12 will be clamped in the inner cavity of the upper beam body 1. Under the pulling force of the tightening spring 34 itself, at this time, the top block 33 will drive the sliding column 32 to continuously move into the inner cavity of the fixed cylinder 31, so that more gas is filled inside the sealing gasket 12, thereby increasing the volume expansion of the sealing gasket 12 and making it more firmly and tightly fit on the inner walls of the upper beam body 1 and the glass frame 2 to improve the sealing performance at the connection between the upper beam body 1 and the glass frame 2.
[0032] Furthermore, the lower end surface of the sealing plug 4 is recessed inward. A pedestal column 41 is fixedly installed on the inner wall of the sealing plug 4. An automatic closing hole 411 is provided in the inner cavity of the pedestal column 41, and the cross-section of the automatic closing hole 411 is in a V-shaped setting;
[0033] An arc groove 42 is formed on the side wall of the sealing plug 4. A sealing rubber ring 43 is fitted and installed on the side wall of the arc groove 42. The sealing rubber ring 43 is arranged at the connection between the sealing plug 4 and the upper beam body 1. Three groups of sealing plugs 4 are equidistantly arranged on the side wall of the upper beam body 1.
[0034] It should be noted that when it is necessary to evacuate or inflate the interlayer of the glass frame 2 from above the upper beam body 1, the user can directly insert the air needle into the self-closing hole 411.
[0035] Furthermore, a second pressure sensor 8 and a temperature sensor 9 are fixedly installed on the inner cavity side wall of the upper beam body 1. The first pressure sensor 6, the second pressure sensor 8 and the temperature sensor 9 are all electrically connected to the numerical control display screen 7. The protective cover 5 is located directly above the sealing plug 4.
[0036] It should be noted that since the lower end surface of the sealing plug 4 is recessed inward, it can guide the air inside the glass frame 2 to squeeze the column 41, thereby further ensuring that the self-closing hole 411 can be in a sealed state. With the protective cover 5 arranged directly above the sealing plug 4, it can ensure that the gas inside the glass frame 2 will not leak. Through the settings of the first pressure sensor 6, the second pressure sensor 8, etc., the air pressure of the glass frame 2 can be monitored in real time, and emergency measures can be taken in time when the sealing plug 4 may leak air.
[0037] Working principle:
[0038] When the user initially installs the entire device, first install the fixed cylinder 31 on the side wall of the glass frame 2, and then assemble the upper beam body 1 into the inner cavity of the glass frame 2. At this time, the upper beam body 1 will squeeze the sealing gasket 12, making it deflated. Finally, the sealing gasket 12 will be clamped in the inner cavity of the upper beam body 1. Under the pulling force of its own tension of the abutting spring 34, at this time, the top block 33 will drive the sliding column 32 to continuously move into the inner cavity of the fixed cylinder 31, so that more gas is filled inside the sealing gasket 12, thereby increasing the volume expansion of the sealing gasket 12 and making it more firmly and closely fit on the inner walls of the upper beam body 1 and the glass frame 2, so as to improve the sealing performance of the connection between the upper beam body 1 and the glass frame 2;
[0039] When it is necessary to evacuate or inflate the interlayer of the glass frame 2 from above the upper beam body 1, the user can directly insert the air needle into the self-closing hole 411. During the operation of the entire device, the lower end face of the sealing plug 4 is recessed inward, which can guide the air inside the glass frame 2 to squeeze the column 41, thereby further ensuring that the self-closing hole 411 can be in a sealed state. With the protective cover 5 arranged directly above the sealing plug 4, it can ensure that the gas in the glass frame 2 will not leak. Through the settings of the first pressure sensor 6, the second pressure sensor 8, etc., the air pressure of the glass frame 2 can be monitored in real time, and emergency measures can be taken in a timely manner when the sealing plug 4 may leak air, greatly improving the service life and use effect of the hollow shutter.
[0040] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
