Description

Technical Field

[0001] This utility model relates to an exhibition display case with a quick-release structure, and more particularly to an exhibition display case with a quick-release structure. Background Technology

[0002] The main functions of exhibition display cases include protecting cultural relics, displaying goods, and enhancing brand image. They also have functions such as dustproofing, moisture-proofing, insect-proofing, and mildew-proofing, further protecting the integrity and safety of cultural relics.

[0003] For example, an exhibition display case with a quick-release structure, authorized by announcement number "CN218551929U", uses a display mechanism and baffle to remove the first rubber ring from the inner wall of the limiting groove. Pulling the fixing block on one side of the insertion rod causes the insertion rod to move outward from the inside of the through hole, thus separating the baffle from the display mechanism and achieving the purpose of quick disassembly of the display mechanism. Pushing the third display platform upward causes the telescopic rod to extend and retract, so that the first, second, and third display platforms can be folded up to save space. It is easy to install and disassemble, saves space and transportation costs. However, the exhibition display case uses a slot and block splicing method. This type of splicing block and slot will deform when splicing and disassembling. Slight force will cause damage to the block, affecting the normal use of the exhibition display case and shortening its service life. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing an exhibition display case with a quick-release structure, which ensures the normal use of the exhibition display case and guarantees its service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This exhibition display case with a quick-release structure includes an outer shell and a door panel. The front of the inner wall of the outer shell is rotatably connected to the outer end of the door panel. A second handle is fixedly connected to the inner side of the front of the door panel. Mounting structures are respectively connected to the left and right sides of the top of the outer shell. A curved block is connected to the top of the mounting structure. A protective cover is fixedly connected to the top of the inner side of the curved block. An opening and closing structure is connected to the front of the protective cover.

[0006] To further improve the installation structure, the mounting structure includes a slotted plate and a straight rod. The outer walls of the two slotted plates are fixedly connected to the top left and right sides of the outer shell, respectively. The front of the inner wall of the slotted plate is inserted into the front of the outer wall of the straight rod. A ring is fixedly connected to the rear of the outer wall of the straight rod. A spring is sleeved on the outer wall of the straight rod. The two ends of the spring are fixedly connected to the front of the ring and the front of the inner wall of the slotted plate, respectively. A bent rod is fixedly connected to the front of the straight rod.

[0007] Further improvements include the top opening of the groove plate being inserted into the outer wall of the curved block.

[0008] Further improvements include connecting the front circular opening of the curved block to the rear end of the outer wall of the straight rod.

[0009] Further improvements are made to the opening and closing structure, which includes a vertical plate and a first handle. The outer rear end face of the vertical plate is in contact with the front face of the cover. The left and right sides of the front face of the vertical plate are respectively fixed to the rear end face of the first handle. The left and right sides of the rear end face of the vertical plate are respectively fixed to a first magnetic sheet. The rear end face of the first magnetic sheet is adsorbed and connected to a second magnetic sheet.

[0010] Further improvements were made, with the outer walls of the two second magnetic sheets being fixedly connected to the left and right sides of the front of the protective cover, respectively.

[0011] The beneficial effects of this utility model are as follows: In this utility model, the curved rod moves forward along with the straight rod in the installation structure. The moving straight rod then moves forward along with the ring, which compresses the spring. Next, the outer wall of the curved block is inserted into the top opening of the groove plate. When the bottom of the protective cover is in contact with the top of the outer shell, the curved rod is released, and the spring, losing pressure, provides a rebound force, causing the ring to move backward. The moving ring, along with the straight rod, moves backward, allowing the rear of the straight rod's outer wall to insert into the front circular opening of the curved block, thus completing the installation of the exhibition display case. During disassembly, the curved rod moves forward along with the straight rod, and the rear of the straight rod's outer wall disengages from the circular opening of the curved block's outer wall. Then, the protective cover is lifted upward, and the cover, along with the curved block, disengages from the groove plate, achieving quick disassembly of the exhibition display case. This ensures the normal use of the exhibition display case and guarantees its service life. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See attached document Figure 1-5 In this embodiment, an exhibition display case with a quick-release structure includes an outer shell 1 and a door panel 4. The front of the inner wall of the outer shell 1 is rotatably connected to the outer end of the door panel 4. The door panel 4 rotates under force through a pin on the front of the inner wall of the outer shell 1. A second handle 5 is fixedly connected to the inner side of the front of the door panel 4. The second handle 5 facilitates pulling the door panel 4 to rotate. The top left and right sides of the outer shell 1 are respectively connected to the mounting structure 2. The top of the mounting structure 2 is connected to the curved block 6. The top of the inner side of the curved block 6 is fixedly connected to the protective cover 7, which is a glass cover. The front of the protective cover 7 is connected to the opening and closing structure 3.

[0021] The mounting structure 2 includes a slotted plate 201 and a straight rod 202. The outer walls of the two slotted plates 201 are fixed to the top left and right sides of the outer shell 1, respectively. The front of the inner wall of the slotted plate 201 is inserted into the front of the outer wall of the straight rod 202. The straight rod 202 moves back and forth through the round opening at the front of the inner wall of the slotted plate 201 when subjected to force. A ring 203 is fixed to the rear of the outer wall of the straight rod 202. A spring 204 is sleeved on the outer wall of the straight rod 202. The two ends of the spring 204 are fixed to the front of the ring 203 and the front of the inner wall of the slotted plate 201, respectively. After the ring 203 moves forward under force, it rebounds due to the elastic force of the spring 204. A bent rod 205 is fixed to the front of the straight rod 202. The bent rod 205 facilitates the forward movement of the straight rod 202. The top opening of the slotted plate 201 is inserted into the outer wall of the curved block 6. The round opening at the front of the curved block 6 is inserted into the rear end of the outer wall of the straight rod 202.

[0022] In the installation structure 2, the bent rod 205 moves forward along with the straight rod 202, and the moving straight rod 202 moves forward along with the ring 203. At this time, the ring 203 compresses the spring 204. Then, the outer wall of the curved block 6 is inserted into the top opening of the groove plate 201. When the bottom of the cover 7 is in contact with the top of the outer shell 1, the bent rod 205 is released, and the spring 204 loses pressure and provides a rebound force, causing the ring 203 to move backward. The moving ring 203 moves the straight rod 202 backward, so that the rear of the outer wall of the straight rod 202 is inserted into the front round opening of the curved block 6, completing the installation of the exhibition display case. During disassembly, the bent rod 205 moves forward along with the straight rod 202, and the rear of the outer wall of the moving straight rod 202 disengages from the round opening of the outer wall of the curved block 6. Then, the cover 7 is lifted upward, and the cover 7, along with the curved block 6, disengages from the inside of the groove plate 201, realizing the quick disassembly of the exhibition display case, ensuring the normal use of the exhibition display case, and guaranteeing the service life of the exhibition display case.

[0023] The opening and closing structure 3 includes a vertical plate 301 and a first handle 302. The vertical plate 301 is a glass plate, and the first handle 302 facilitates the movement of the vertical plate 301. The outer side of the rear end face of the vertical plate 301 is in contact with the front side of the protective cover 7. The left and right sides of the front side of the vertical plate 301 are respectively fixed to the rear end face of the first handle 302. The left and right sides of the rear end face of the vertical plate 301 are respectively fixed to a first magnetic sheet 303, which is a positive electrode. The rear end face of the first magnetic sheet 303 is adsorbed and connected to a second magnetic sheet 304, which is a negative electrode. The adsorption strength of the first magnetic sheet 303 and the second magnetic sheet 304 is selected according to the requirements. The outer walls of the two second magnetic sheets 304 are respectively fixed to the left and right sides of the front side of the protective cover 7.

[0024] Working principle:

[0025] Exhibition display case assembly and disassembly:

[0026] Pulling the curved rod 205 moves the straight rod 202 forward, and the moving straight rod 202 moves the ring 203 forward. At this time, the ring 203 compresses the spring 204. Then, the outer wall of the curved block 6 is inserted into the top opening of the slot plate 201. When the bottom of the cover 7 is in contact with the top of the outer shell 1, the curved rod 205 is released. The spring 204 loses pressure and provides a rebound force, causing the ring 203 to move backward. The moving ring 203 moves the straight rod 202 backward, so that the rear of the outer wall of the straight rod 202 is inserted into the front round opening of the curved block 6, completing the installation of the exhibition display case. When disassembling, the curved rod 205 moves the straight rod 202 forward, and the rear of the outer wall of the moving straight rod 202 disengages from the round opening of the outer wall of the curved block 6. Then, the cover 7 is lifted upward, and the cover 7, along with the curved block 6, disengages from the inside of the slot plate 201, realizing the quick disassembly of the exhibition display case.

[0027] Exhibition display case and exhibit placement:

[0028] Pulling the first handle 302 forward causes the upright plate 301 to move forward, disengaging the first magnetic piece 303 from the second magnetic piece 304. At this point, the front of the protective cover 7 opens, and the exhibit is placed inside the protective cover 7. Simultaneously, the bottom of the exhibit is attached to the top of the outer shell 1. Then, the back of the upright plate 301 is attached to the front of the protective cover 7, at which point the first magnetic piece 303 and the second magnetic piece 304 are attracted and connected. Both the protective cover 7 and the upright plate 301 are made of transparent glass to display the exhibits inside.

[0029] Pull the second handle 5 forward with your hand, so that the second handle 5 rotates the door panel 4 forward. At this time, the front of the outer shell 1 opens, and cleaning items can be stored inside the outer shell 1. Then, rotate the door panel 4 back to close the outer shell 1.

[0030] Example 2:

[0031] See attached document Figure 1-5In this embodiment, an exhibition display case with a quick-release structure also includes a concave plate 8 and a square plate 9. The outer sides of the two concave plates 8 are respectively fixed to the left and right sides of the inner wall of the protective cover 7, and the inner wall of the concave plate 8 is inserted into the outer wall of the square plate 9.

[0032] Working principle:

[0033] When the exhibits are small, the square plate 9 can be inserted into the inner wall of the concave plate 8, so that the square plate 9 forms two spaces inside the protective cover 7. The first exhibit is placed below the square plate 9, and the other exhibit is placed above the square plate 9. The square plate 9 is also made of transparent glass, so it does not affect the direct observation of the exhibits in the two positions.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
