Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cultural relic exhibition device, more particularly to a display frame with fireproof performance. BACKGROUND

[0002] The prior art such as the Chinese patent with the publication number "CN221653981U" discloses a double-sided display frame for cultural relic exhibition, comprising frame bodies with open mouths arranged on opposite sides, air inlet valves and air outlet valves arranged on the frame bodies, transparent cover plates covering the two open mouths, outer frames pressing the transparent cover plates on the frame bodies respectively, and fixing assemblies and humidity control assemblies arranged on the inner surfaces of the frame bodies respectively.

[0003] However, the above-mentioned double-sided display frame lacks protection of cultural relics in special environments. For example, in the case of fire, the frame body will deform due to high temperature when the exhibition frame is in a high-temperature environment. Many cultural relics in the frame body are flammable materials such as paper and cloth. As the ambient temperature rises to the corresponding ignition point, the frame body, outer frame, and cover plate will transfer heat, and they do not have heat insulation and heat resistance. In a high-temperature environment, these components will deform and cause the cultural relics to directly contact the high-temperature gas outside, which will quickly raise the temperature inside the frame body. When the temperature of the frame body or the components in contact with the cultural relics reaches the ignition point of the cultural relics, the cultural relics in the frame body will be ignited or self-ignited. SUMMARY

[0004] The utility model discloses a display frame with fireproof performance, which can isolate the influence of high temperature outside on cultural relics and avoid damage to cultural relics in a high-temperature environment.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of a display frame with fireproof performance, comprising a frame body, air inlet valves and air outlet valves arranged on the frame body, and a clamping assembly for fixing cultural relics installed in the frame body.

[0006] In the above technical solution, the heat insulation board can be two first high-temperature resistant glass boards made of high-temperature resistant glass, or a plate-like structure made of materials such as glass fiber, asbestos, rock wool, silicate, etc. The first high-temperature resistant glass board allows the cultural relics placed in the frame to be viewed from the outside. The frame and the outer frame are also coated with a fire-resistant coating. In a fire environment or a high-temperature environment, the fire-resistant coating, the first high-temperature resistant glass board, and the heat insulation board can isolate the external heat from being transferred to the cultural relics, so that the temperature of the cultural relics in the frame is maintained at a low level, ensuring that the cultural relics will not be ignited or spontaneously combust.

[0007] Furthermore, the clamping assembly includes a clamping seat connected to the frame, a clamping plate connected to the clamping seat, and a fastener connecting the clamping plate and the clamping seat. A clamping cavity for accommodating cultural relics is formed between the clamping seat and the clamping plate. Tightening or loosening the fastener adjusts the tightness of the connection between the clamping plate and the clamping seat, and also adjusts the size of the clamping cavity to accommodate cultural relics of varying thicknesses.

[0008] Furthermore, it also includes two heat-insulating pressure plates for pressing cultural relics, the heat-insulating pressure plates are located in the clamping cavity and the clamping plates and the clamping seat clamp the heat-insulating pressure plates; at least one of the two heat-insulating pressure plates is a second high-temperature resistant glass plate and is located on the side close to the first high-temperature resistant glass plate. The heat-insulating pressure plates can press cultural relics, and are generally applicable to cultural relics with thin structures, such as paper, cloth, etc. The cultural relics are placed between the two heat-insulating pressure plates. After the heat-insulating pressure plates press the cultural relics, the clamping assembly only needs to clamp the heat-insulating pressure plates to fix the cultural relics in the frame. The clamping assembly does not need to directly contact the cultural relics and can avoid blocking the contents of the cultural relics. The heat-insulating pressure plates can further isolate the cultural relics from the external environment. At a fire scene or in a high-temperature environment, the outside temperature is less likely to affect the isolated temperature. The second high-temperature resistant glass plate will not affect the display of the cultural relics.

[0009] Furthermore, a fireproof cloth is included, which is located between the two heat-insulating pressure plates. The cultural relics are placed on the fireproof cloth, usually with the back of the cultural relics attached to the fireproof cloth, and the fireproof cloth can further isolate the heat from the heat-insulating pressure plates to the cultural relics.

[0010] Furthermore, the minimum width of the clamping cavity is less than the thickness of the two superimposed heat-insulating pressure plates. The fasteners of the clamping assembly do not need to be tightened to the tightest state to clamp the two heat-insulating pressure plates, which reduces the operation of tightening the fasteners and leaves room for placing cultural relics.

[0011] Furthermore, the frame includes a plurality of splicing units connected in sequence and forming a ring, and adjacent splicing units are connected by snap-fit ​​connections and fasteners. The frame is spliced ​​together by a plurality of splicing units, and the splicing units are connected at the splicing points by snap-fit ​​connections and fastener connections. When deformation occurs due to the influence of temperature, if a high temperature occurs at the snap-fit ​​connection, the snap-fit ​​position is snapped more tightly due to deformation, and the frame is not easily damaged, resulting in heat being directly transferred into the frame. At the same time, when assembling the frame, the snap-fit ​​connection is first used and then the fasteners are installed. There is no need to position the fasteners when installing them, making assembly more convenient.

[0012] Furthermore, the splicing unit includes two cross beam units, two longitudinal beam units and four corner block units, and both sides of the splicing unit are respectively provided with a clamping part and a claw part that can be used to engage with other splicing units; one end of the corner block unit is engaged with the cross beam unit, and the other end is engaged with the longitudinal beam unit; the clamping parts of adjacent splicing units are provided with connecting holes, and the fasteners pass through the connecting holes to connect the adjacent splicing units.

[0013] Furthermore, the frame includes a locking pin that connects adjacent splicing units. After splicing, the adjacent splicing units form a mounting groove and a locking hole at the splicing joint. The locking pin is installed in the mounting groove and is provided with an insert that fits into the locking hole. The locking holes are located at the splicing joint of the two splicing units. After the two splicing units are spliced, the locking pin can further strengthen the connection strength.

[0014] Furthermore, the outer surface of the corner block unit is provided with a hanging portion, which can facilitate hanging the display frame for display.

[0015] Furthermore, the air inlet valve and the air outlet valve are both high temperature resistant valves, which are not easily damaged in a high temperature environment.

[0016] Compared with existing technologies, the present invention offers the following advantages: the fire-retardant-coated outer frame, frame body, and heat-insulating panels can isolate cultural relics from external heat. Even when the display frame is exposed to fire or other high-temperature environments, the cultural relics within the display frame are protected from damage. Furthermore, the fact that one of the heat-insulating panels is made of high-temperature-resistant insulating glass does not affect the display of the cultural relics under normal circumstances.

[0023] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0024] Example 1

[0025] like Figures 1-2 The figure shows an embodiment of a fire-resistant display frame, comprising a frame 100, an air inlet valve and an air outlet valve both provided on the frame 100, and a clamping assembly 200 installed within the frame 100 for securing cultural relics. The frame 100 has openings on two opposing sides. The frame 100 also includes insulation panels 300 covering the two openings, respectively, and an outer frame 400 for pressing the insulation panels 300 against the frame 100. At least one of the two insulation panels 300 is a first high-temperature resistant glass panel. The outer surfaces of the frame 100 and the outer frame 400 are both coated with a fire-resistant coating.

[0026] Specifically, the clamping assembly 200 includes a clamping seat 210 connected to the frame 100, a clamping plate 220 connected to the clamping seat 210, and a fastener connecting the clamping plate 220 and the clamping seat 210. A clamping cavity 230 for accommodating cultural relics is formed between the clamping seat 210 and the clamping plate 220. By tightening or loosening the fastener, the tightness of the connection between the clamping plate 220 and the clamping seat 210 can be adjusted. The size of the clamping cavity 230 can also be adjusted to clamp cultural relics of varying thicknesses. In this embodiment, four clamping assemblies 200 are provided, located on the four inner side surfaces of the frame 100. The four clamping assemblies 200 simultaneously clamp the cultural relics, providing a good fixing effect.

[0027] In this embodiment, two insulating pressure plates 500 are further included for compressing the cultural relics, and a pressure plate 500 is positioned between the two insulating pressure plates 500. The insulating pressure plates 500 are located within the clamping cavity 230 and are clamped by the clamping plate 220 and the clamping seat 210. At least one of the two insulating pressure plates 500 is a second high-temperature resistant glass plate and is located on the side close to the first high-temperature resistant glass plate. The insulating pressure plates 500 can compress the cultural relics and are generally suitable for thin cultural relics such as paper and cloth. The cultural relics are placed between the two insulating pressure plates 500 with their backs attached to the fireproof cloth 600. After the insulating pressure plates 500 compress the cultural relics, the clamping assembly 200 only needs to clamp the insulating pressure plates 500 to secure the cultural relics within the frame 100. The clamping assembly 200 does not need to directly contact the cultural relics and can avoid obstructing the contents of the cultural relics. The insulating pressure plates 500 can further isolate the cultural relics from the external environment. In a fire scene or high-temperature environment, the external temperature is less likely to affect the isolated temperature. The second high temperature resistant glass plate will not affect the display of the cultural relics. The fireproof cloth 600 can further isolate the heat from the heat insulation pressing plate 500 to the cultural relics.

[0028] In this embodiment, the minimum width of the clamping cavity 230 is less than the thickness of the two superimposed heat-insulating pressure plates 500. The fasteners of the clamping assembly 200 do not need to be tightened to the maximum to clamp the two heat-insulating pressure plates 500, reducing the need for tightening the fasteners and leaving room for inserting cultural relics.

[0029] The working principle and usage of this embodiment are as follows: Place the cultural relics on the fireproof cloth 600, then two heat-insulating pressure plates 500 press the cultural relics and the fireproof cloth 600 together, place the heat-insulating pressure plates 500 into the clamping cavity 230, tighten the fasteners so that the clamping plates 220 clamp the heat-insulating pressure plates 500 onto the clamping seat 210. Install the heat-insulating plate 300 on the frame 100, with the first heat-resistant heat-insulating glass plate and the second heat-resistant heat-insulating glass plate on the same side, so that the cultural relics can be displayed. Then install the outer frame 400 to fix the heat-insulating plate 300 on the frame 100. The heat-insulating plate 300 can be two first heat-resistant glass plates made of heat-resistant glass, or a plate-like structure made of materials such as glass fiber, asbestos, rock wool, silicate, etc. The first heat-resistant glass plate allows the cultural relics placed in the frame to be viewed from the outside. The frame 100 and the outer frame 400 are also coated with a fire-resistant coating. In a fire or high-temperature environment, the fire-retardant coating, the first high-temperature resistant glass plate and the insulation board can isolate the external heat from being transferred to the cultural relics, so that the temperature of the cultural relics in the frame is maintained at a low level, ensuring that the cultural relics will not be ignited or spontaneously combust.

[0030] The beneficial effects of this embodiment include: the fire-retardant-coated outer frame 400, the frame body 100, and the heat shield 300 effectively shield cultural relics from external heat. Even when the display frame is exposed to fire or other high-temperature environments, the cultural relics within the frame remain protected from damage. Furthermore, the fact that one of the heat shields 300 is made of high-temperature insulating glass does not affect the display of cultural relics under normal conditions. Testing has shown that the display frame of this embodiment can protect cultural relics within the frame even at temperatures of 500 degrees Celsius.

[0031] Example 2

[0032] Embodiment 2 of a display frame with fireproof performance is different from embodiment 1 in that: Figure 3 As shown, the frame 100 is further defined.

[0033] The frame 100 includes a plurality of splicing units connected in sequence and forming a ring, and adjacent splicing units are connected by snap-fitting and fasteners. The frame 100 is spliced ​​together by a plurality of splicing units, and the splicing units are connected by snap-fitting and fasteners at the splicing locations. When deformation occurs due to temperature influence, if a high temperature occurs at the snap-fitting location, the snap-fitting position snaps more tightly due to deformation, and the frame 100 is not easily damaged, resulting in heat being directly transferred into the frame 100. At the same time, when assembling the frame 100, the snap-fitting is first performed and then the fasteners are installed. There is no need to perform positioning when installing the fasteners, and assembly is more convenient.

[0034] In this embodiment, the splicing unit includes two cross beam units 110, two longitudinal beam units 120 and four corner block units 130. Both sides of the splicing unit are respectively provided with a snap-fitting portion 140 and a claw portion 150 that can be used to engage with other splicing units; one end of the corner block unit 130 is engaged with the cross beam unit 110, and the other end is engaged with the longitudinal beam unit; the engaging portion of adjacent splicing units is provided with a connecting hole 160, and the fastener passes through the connecting hole 160 to connect the adjacent splicing units.

[0035] In this embodiment, the frame 100 includes a locking pin 170 that connects adjacent splicing units. After the adjacent splicing units are spliced, a mounting groove 180 and a locking hole 181 are formed at the splicing joint. The locking pin 170 is installed in the mounting groove 180 and has an insertion portion 171 that fits into the locking hole 181. The locking hole 181 is located at the splicing joint of the two splicing units. After the two splicing units are spliced, the locking pin 170 can further strengthen the connection strength.

[0036] In addition, a hanging portion is provided on the outer surface of the corner block unit 130. The hanging portion can facilitate hanging display of the display frame.

[0037] In this embodiment, the outer frame 400 is divided into multiple components, and each component is detachably connected to the outer surface of the frame body 100 via fasteners.

[0038] Compared to Example 1, the frame 100 and outer frame 400 of this embodiment are both composed of multiple components. During the processing stage, only the individual components need to be processed and then assembled, eliminating the need to use large-area raw materials for integrated processing, thus saving processing costs. The splicing units of the frame 100 are connected by both snap connections and fasteners. Not only can the snap connections be pre-positioned before fasteners are used, but they can also ensure that the connections between the splicing units become tighter when the frame 100 actually deforms.

[0039] The remaining features and working principles of this embodiment are consistent with those of embodiment 1.

[0040] Example 3

[0041] Embodiment 3 of a fireproof display frame differs from Embodiment 1 or Embodiment 2 in that both the air inlet valve and the air outlet valve are high-temperature resistant valves. High-temperature resistant valves are less susceptible to damage in high-temperature environments. The partitions and the insulating pressure plate are both made of insulating and high-temperature resistant glass.

[0042] The remaining features and effects of this embodiment are consistent with those of embodiment 1 or embodiment 2.

[0043] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
