Description

Technical Field

[0001] The utility model relates to the field of electrically heated glass, and more particularly to electrically heated glass for museum display cabinets and a mounting structure thereof. Background Art

[0002] The primary function of museum glass display cases is to protect exhibits from external environmental factors, preventing dust, moisture, and other erosions. For paper artifacts or easily oxidized metal artifacts, such as ancient calligraphy and paintings, and bronze artifacts, well-sealed glass display cases can create a relatively stable microenvironment, slowing the aging process. Generally speaking, artifacts are best stored at a temperature between 18°C ​​and 22°C.

[0003] To maintain a uniform temperature inside the showcase, existing showcases mostly use electrically heated glass. This involves installing an electrically heated film inside the double-layer glass. The temperature inside the showcase is controlled by controlling the current. However, the electrodes of the existing electrically heated glass are welded to the internal film, resulting in localized bulges on the sides of the glass. Furthermore, the glass panels are glued to the showcase, making them difficult to disassemble and maintain. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 4 As shown, the electrically heated glass for museum showcases includes an electrically heated glass plate 3. The edge of the electrically heated glass plate 3 is wrapped with a rubber insulating edge guard 4. The cross-section of the rubber insulating edge guard 4 is a U-shaped structure. The rubber insulating edge guard 4 can effectively wrap the side of the electrically heated glass plate 3 to prevent leakage and effectively protect it. The electrically heated glass plate 3 is composed of at least two layers of glass sheets 31, mostly two or three layers of glass. An electrically heated film 32 is arranged between two adjacent glass sheets 31. The temperature of the electrically heated film 32 is controlled by powering on. A notch is provided on one side of the inner glass sheet 31 and the electrically heated film 32, that is, the size is smaller than the outer glass sheet 31, so as to facilitate the installation of the electrode sheet 33. The edge of the electrically heated film 32 placed at the notch is coated with silver paste, which can make the electrically heated film 32 uniformly conductive while sealing the edge. The silver paste is connected to the electrode sheet 33 through a conductive tape. The outer side of the electrode sheet 33 is connected to a power line. The electrode sheet 33 passes through the rubber insulating edge guard 4.

[0025] Example 2:

[0026] The installation structure of heated glass for museum display cabinets includes an exhibition frame 1 and an installation limit mechanism 2. The exhibition frame 1 is composed of angle steels to form a rectangular three-dimensional frame, which is convenient for display at multiple angles. A limit ridge 11 is provided on the inner edge of the exhibition frame 1. The limit ridge 11 and the exhibition frame 1 form a step shape. The four limit ridges 11 on the same side are equal in size to the electrically heated glass plate 3. The electrically heated glass plate 3 is placed inside the four-side limit ridges 11. The thickness of the rubber insulating edge guard 4 is less than the limit ridge 11, so that after the electrically heated glass plate 3 is installed in place, the front side is limited by the inner side of the angle steel and the rear side is limited by the limit plate 22. Notch grooves 12 are symmetrically opened on the surface of the limit ridge 11, and the installation limit mechanism 2 is installed inside the notch groove 12.

[0027] Please refer to Figure 2 and Figure 3 As shown, the installation limit mechanism 2 includes a rotating shaft 21 rotating inside the notch groove 12, and a limit plate 22 is provided on the upper surface of the rotating shaft 21. When the limit plate 22 is in a vertical state, the rear side of the rubber insulating edge guard 4 can be squeezed and fixed. The limit plate 22 corresponds to the inner surface of the rubber insulating edge guard 4.

[0028] Among them, a control swing rod 23 is tiltedly arranged at the bottom of the rotating shaft 21, and an angle of 135° is formed between the limit plate 22 and the control swing rod 23. When the limit plate 22 is vertically upward, the control swing rod 23 tilts backward. Conversely, when the control swing rod 23 tilts forward, the limit plate 22 can be driven to rotate backward so that it is retracted into the notch groove 12, which is convenient for the installation of the glass plate. A U-shaped groove 24 is provided on the surface of the control swing rod 23, and the bottom of the U-shaped groove 24 is open. The open bottom facilitates the installation of the U-shaped slider 25.

[0029] Please refer to Figure 3 As shown, a U-shaped slider 25 is symmetrically and slidingly installed inside the U-shaped groove 24, and the two U-shaped sliders 25 slide on the two side edges of the U-shaped groove 24 respectively. An internal threaded cylinder 26 is rotatably installed between the two U-shaped sliders 25, and the internal threaded cylinder 26 is horizontally set. A threaded rod 27 is rotatably installed on the inner side of the limiting ridge 11, and the rear end of the threaded rod 27 rotates and passes through the internal threaded cylinder 26. A hexagon socket bolt head 28 is provided at the front end of the threaded rod 27, and the hexagon socket bolt head 28 is flush with the front surface of the exhibition frame 1, so that the outer surface of the exhibition frame 1 is flush. When the threaded rod 27 rotates, the internal threaded cylinder 26 can be controlled to move axially, and then the limiting plate 22 can be controlled to swing.

[0030] Working principle: During installation, the hexagon socket bolt head 28 can be first rotated on the outside with a tool to allow the controllable internal threaded barrel 26 to move axially. Since the internal threaded barrel 26 and the U-shaped slider 25 can rotate, the U-shaped slider 25 can drive the control swing rod 23 to swing during the axial movement of the internal threaded barrel 26. When the bottom of the control swing rod 23 rotates forward, the limit plate 22 can be rotated backward. When the limit plate 22 is completely immersed in the notch groove 12, the surface of the limit ridge 11 is flush, and the electrically heated glass plate 3 can be installed on the limit ridge 11. Then, the hexagon socket bolt head 28 is rotated in the opposite direction to make the limit plate 22 rotate upward until the limit plate 22 is in a vertical state and squeezes the rubber insulating edge guard 4. At this time, the electrically heated glass plate 3 can be effectively fixed to maintain the stability of the electrically heated glass plate 3 after installation.

[0031] The electric heating film 32 placed at the notch is coated with silver paste, and the electrode sheet 33 is connected to the silver paste with conductive tape to realize power control of the electric heating film 32. The end of the electrode sheet 33 is connected to a power line, and the power lines of multiple electrode sheets 33 on the inside of the exhibition frame 1 are connected to the same switch.

[0032] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
