Technical Field

[0001] The utility model relates to the technical field of display cabinets, in particular to a sealed cultural relic display cabinet. Background Art

[0002] A museum is a place that collects, preserves, displays and studies physical objects representing the cultural heritage of nature and humanity. It is an institution, building, place or social public institution that classifies and manages the collections and provides the public with knowledge, education and appreciation of cultural education. When exhibiting cultural relics, display cabinets are needed to protect the cultural relics to prevent damage and oxidation caused by the external environment. However, the display cabinets used in existing museums have poor sealing, which makes the internal environment of the display cabinets easily affected by external influences and changes, causing oxidation and fading of the cultural relics.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Please refer to 1-3, a sealed cultural relic display cabinet includes: a base 1, a glass cover 2 is provided on the upper side of the base 1, a U-shaped air bag 4 is embedded in the base 1, a rubber sleeve 3 is sleeved on the lower end of the glass cover 2, one end of the glass cover 2 sleeved with the rubber sleeve 3 is inserted into the U-shaped air bag 4, a contact rod 21 is provided on the inner side of the glass cover 2, a contact switch is provided in the base 1, and the contact rod 21 abuts against the contact switch.

[0022] Specifically, the present invention inserts the glass cover 2 into the base 1, causing the rubber sleeve 3 to squeeze the U-shaped airbag 4, so that the gas in the U-shaped airbag 4 is transferred, and the U-shaped airbag 4 is tightly attached to the rubber sleeve 3 and the inner and outer sides of the glass cover 2, thereby enhancing the sealing of the cultural relics display cabinet. In addition, a contact rod 21 is provided on the inner side of the glass cover 2. When the glass cover 2 is inserted into the base 1, the contact rod 21 abuts against the contact switch, connecting the circuit of the electrical appliance set in the base 1, so that the auxiliary equipment such as the lamp 6 set in the base 1 is turned on, which makes it easier for staff to judge the usage status of the cultural relics display cabinet.

[0023] Furthermore, semicircular protrusions are provided on the inner and outer sides of the rubber sleeve 3 .

[0024] Specifically, the rubber sleeve 3 is sleeved around the lower end of the glass cover 2. When the glass cover 2 is inserted into the U-shaped airbag 4, the gas in the U-shaped airbag 4 is squeezed to both sides, so that the U-shaped airbag 4 is tightly pressed against the rubber sleeve 3 and both sides of the glass cover 2. By setting the two sides of the rubber sleeve 3 as semicircular protrusions, on the one hand, the contact surface between the rubber sleeve 3 and the U-shaped airbag 4 is smooth and has no gaps, and on the other hand, the contact surface between the U-shaped airbag 4 and the rubber sleeve 3 is a curved surface, so that the force transmitted by the U-shaped airbag 4 to different parts of the rubber sleeve 3 is different, thereby enhancing the sealing of the cultural relics display case.

[0025] Furthermore, a first permanent magnet 31 is embedded in the bottom end of the rubber sleeve 3 , and a second permanent magnet 5 is provided in the base 1 . The second permanent magnet 5 is located at the lower end of the U-shaped airbag 4 .

[0026] Specifically, the second permanent magnet 5 is fixedly installed in the base 1 and is located directly below the U-shaped airbag 4. When the glass cover 2 is inserted into the U-shaped airbag 4, the first permanent magnet 31 in the rubber sleeve 3 and the second permanent magnet 5 are attracted to each other, so that the gas at the bottom layer of the U-shaped airbag 4 is squeezed more thoroughly, and the air pressure on both sides of the U-shaped airbag 4 is greater, thereby making the U-shaped airbag 4 exert a greater squeezing force on the rubber sleeve 3 and the glass cover 2, and the sealing of the cultural relics display cabinet is more stable.

[0027] Furthermore, a display stand 11 is provided at the top of the base 1 , and four lamps 6 are provided around the display stand 11 , and the four lamps 6 are electrically connected to the contact switch.

[0028] Specifically, after the glass cover 2 is placed on the base 1, the contact rod 21 abuts the contact switch, so that the lamp 6 is powered on and lights up, which can better facilitate the display of cultural relics. The working status of the lamp 6 can be used to determine whether the cultural relics display cabinet is working normally, which is convenient for staff to carry out timely maintenance.

[0029] Furthermore, the contact switch includes a contact switch base 12, in which a contact switch protrusion 13 and a spring 14 are provided. The contact switch protrusion 13 is connected to the contact switch base 12 through the spring 14, and the concave surface of the contact switch base 12 and the convex surface of the contact switch protrusion 13 are both provided with power-on endpoints.

[0030] Specifically, one end of the spring 14 is fixedly connected to the inner cavity wall of the contact switch base 12, and the other end of the spring 14 is fixedly connected to the top of the contact switch protrusion 13. The contact switch base 12 and the contact switch protrusion 13 are both connected by wires. When the glass cover 2 is covered on the base 1, the contact rod 21 presses the contact switch protrusion 13, causing the contact switch protrusion 13 to overcome the elastic force of the spring 14 and move downward until the energized end point on the convex surface of the contact switch protrusion 13 contacts the energized end point on the concave surface of the contact switch base 12, so that the circuit in the cultural relics display cabinet is connected, and the lamp 6 and other electronic devices are operated normally.

[0031] Furthermore, the rubber sleeve 3 is made of hard rubber.

[0032] Specifically, the rubber sleeve 3 is made of hard rubber, which facilitates the installation of the first permanent magnet 31 and facilitates the insertion of the rubber sleeve 3 into the U-shaped airbag 4 and the squeezing effect on the U-shaped airbag 4 .

[0033] In this utility model, reference is made to Figures 1 to 3 First, the rubber sleeve 3 is sleeved around the lower end of the glass cover 2, and then the glass cover 2 is inserted into the U-shaped air bag 4 in the base 1. Then, the glass cover 2 is pressed downward, and the first permanent magnet 31 and the second permanent magnet 5 are attracted to each other, so that the bottom end of the U-shaped air bag 4 is squeezed into a thin layer. At this time, the air pressure on both sides of the U-shaped air bag 4 becomes high, tightly wrapping the glass cover 2 and the rubber sleeve 3, which not only enhances the sealing of the cultural relics display case, but also enhances the stability of the glass cover 2 on the base 1. At the same time, after the first permanent magnet 31 and the second permanent magnet 5 are attracted, the contact rod 21 makes the contact switch protrusion 13 abut against the contact switch base 12, so that the electronic devices in the cabinet are energized. When the cultural relics display case needs to be opened, the power supply of the cultural relics display case is cut off, so that the second permanent magnet 5 loses its magnetic force, thereby facilitating the glass cover 2 to be pulled out of the U-shaped air bag 4.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
