Description

Technical Field

[0001] This utility model relates to the field of cultural relic display cases, specifically to the opening structure of cultural relic display case doors. Background Technology

[0002] As an important carrier of cultural relics, display cases can greatly enhance or limit the display effect of exhibitions. Traditional display cases mostly consist of a base and a transparent glass cover, and their doors open in the following ways: sliding, automatic lifting, lifting, and unfolding.

[0003] The existing lift-up opening mechanism for artifact display cases sometimes results in staff not being able to control the force when closing the glass doors properly, which can increase the contact and collision force between the glass doors and the display cases, potentially damaging the glass display cases and thus affecting the display effect of the artifacts.

[0004] Therefore, in view of this, the inventors studied and improved the existing structure and its shortcomings, and provided an opening structure for the artifact display case door in order to achieve a more practical purpose. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an opening structure for the doors of cultural relic display cases, so as to solve the technical problem that if staff do not control the force properly, it will increase the contact and collision force between the glass door and the display case, causing damage to the glass display case.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an opening structure for a cultural relic display case door, comprising a display case body, an installation groove on the upper surface of the display case body, a fixing block inside the installation groove, a locking mechanism and a buffer mechanism on the fixing block, the buffer mechanism comprising a fixing rod, a movable rod rotatably connected to the fixing rod via a rotating shaft, a roller rotatably connected to the other end of the movable rod, and a spring fixedly connected between the fixing rod and the movable rod.

[0007] By adopting the above technical solution, when the display case door needs to be closed, pressing the movable plate causes it to rotate and connect with the fixed plate via a pivot. As the movable plate continues to press down, the mounting plate extends into the mounting groove. At the same time, the mounting plate squeezes the rollers, and the movable rod rotates via the pivot and the fixed rod. Then, the spring is stretched. Utilizing the elasticity of the spring, the impact force when the rollers contact the mounting plate is reduced, which helps to effectively protect the glass display case and prevent damage.

[0008] Furthermore, a fixed plate is fixedly installed on the top of the main body of the display case, and a movable plate is rotatably connected to one side of the fixed plate via a pivot. Both the fixed plate and the movable plate are made of transparent glass.

[0009] By adopting the above technical solution and setting the fixed plate and movable plate to be made of transparent glass, it is beneficial to provide a better viewing effect for cultural relics.

[0010] Furthermore, an mounting plate is fixedly installed on the inner side of the movable plate, the mounting plate and the surface of the roller are in contact, and the fixing rod is fixedly connected to the fixing block.

[0011] By adopting the above technical solution, and through the setting of the rollers, when the mounting plate squeezes the rollers, it is beneficial to transform sliding friction into rolling friction.

[0012] Furthermore, the engaging mechanism includes locking teeth, which are rotatably connected to the fixed block via a torque shaft.

[0013] By adopting the above technical solution and setting the torque shaft, it is beneficial to ensure that the tooth tip of the clamping tooth is always in contact with the inner wall of the mounting groove.

[0014] Furthermore, the tooth end face of the locking tooth is set with an inclined surface, one side of the bottom of the mounting plate is set with an inclined surface, and a locking groove is opened on the mounting plate, and the locking tooth and the locking groove engage with each other.

[0015] By adopting the above technical solution, and by setting one side of the bottom of the mounting plate and the end face of the tooth of the locking tooth to be inclined, when the mounting plate presses the locking tooth, it is beneficial for the locking tooth to engage with the locking groove.

[0016] Furthermore, a lever is fixedly connected to the locking tooth, and the end of the lever away from the locking tooth extends through the side wall of the display case body to the outside. The mounting plate is adapted to the mounting groove, and a placement plate is fixedly connected to the lower interior of the display case body.

[0017] By adopting the above technical solution, the placement of the display board facilitates the placement of cultural relics.

[0018] Furthermore, there are two mounting slots, two mounting plates, and the outer surface of the roller is made of rubber.

[0019] By adopting the above technical solution and setting the surface of the roller to a rubber material, it is beneficial to further reduce the collision force between the roller and the mounting plate.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model uses a movable rod, spring, and rollers. When the display case door needs to be closed, pressing the movable plate causes it to rotate and connect with the fixed plate via a pivot. As the movable plate continues to press down, the mounting plate extends into the mounting groove. At the same time, the mounting plate squeezes the rollers. The movable rod rotates via the pivot and the fixed rod, which then stretches the spring. Utilizing the elasticity of the spring, the impact force when the roller contacts the mounting plate is reduced, which helps to effectively protect the glass display case and prevent damage.

[0022] 2. This utility model, by setting a locking tooth and a locking groove, allows the mounting plate to continuously press down during the closing of the cabinet door. The inclined surface of the mounting plate's bottom plate contacts the inclined surface of the locking tooth's end. Then, due to the squeezing force of the mounting plate, the locking tooth rotates via a torsion shaft. Subsequently, due to the nature of the torsion shaft, the locking tooth engages with the locking groove. When it is necessary to open the cabinet door, a lever is moved, causing the locking tooth to rotate and separate from the locking groove. The movable plate is then lifted, facilitating the use of the artifact display case. Setting the locking tooth and locking groove inside the mounting groove enhances the aesthetics of the artifact display case and improves the viewing experience of the artifacts.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] The opening structure of the artifact display case door, as shown in Figures 1-4, includes a display case body 1. The upper surface of the display case body 1 has an installation groove 2. A fixing block 7 is set inside the installation groove 2. The fixing block 7 is equipped with a locking mechanism 8 and a buffer mechanism 9. The buffer mechanism 9 includes a fixing rod 901. The fixing rod 901 is rotatably connected to a movable rod 902 via a rotating shaft. The other end of the movable rod 902 is rotatably connected to a roller 903. A spring 904 is fixedly connected between the fixing rod 901 and the movable rod 902.

[0031] See Figure 1 and 2 A fixed plate 3 is fixedly installed on the top of the main body 1 of the display case. A movable plate 4 is rotatably connected to one side of the fixed plate 3 via a pivot. Both the fixed plate 3 and the movable plate 4 are made of transparent glass. By making the fixed plate 3 and the movable plate 4 transparent glass, it is beneficial to provide a better viewing effect for cultural relics and improve the practicality of the cultural relic display case.

[0032] See Figure 1 , 2 3 and 4, the inner side of the movable plate 4 is fixedly installed with the mounting plate 6, the surface of the mounting plate 6 and the roller 903 are in contact, the fixing rod 901 is fixedly connected to the fixing block 7. By setting the roller 903, when the mounting plate 6 squeezes the roller 903, it is beneficial to change the sliding friction into rolling friction, which is beneficial to reduce the friction between the mounting plate 6 and the roller 903 and improve the service life of the cultural relic display case.

[0033] See Figure 1 , 2 3 and 4, the engaging mechanism 8 includes a locking tooth 802, which is rotatably connected to the fixing block 7 via a torque shaft 801. The torque shaft helps to keep the tooth tip of the locking tooth 802 in contact with the inner wall of the mounting groove 2, thereby making the locking tooth 802 and the groove 803 more securely engaged.

[0034] See Figure 2 , 3 4. The tooth end face of the locking tooth 802 is set with an inclined surface, and the bottom side of the mounting plate 6 is set with an inclined surface. The mounting plate 6 has a locking groove 803. The locking tooth 802 and the locking groove 803 are engaged. By setting the bottom side of the mounting plate 6 with an inclined surface and the tooth end face of the locking tooth 802 with an inclined surface, when the mounting plate 6 squeezes the locking tooth 802, it is beneficial for the locking tooth 802 to engage with the locking groove 803, and it is convenient to use the squeezing force of the mounting plate 6 to engage with the locking tooth 802.

[0035] See Figure 1 , 24. A lever 804 is fixedly connected to the locking tooth 802. The end of the lever 804 away from the locking tooth 802 extends through the side wall of the display case body 1 to the outside. The mounting plate 6 is adapted to the mounting groove 2. A placement plate 5 is fixedly connected to the lower interior of the display case body 1. The placement plate 5 facilitates the placement of cultural relics on the placement plate 5. The lever 804 facilitates the rotation of the locking tooth 802 by moving the lever 804.

[0036] The implementation principle of this embodiment is as follows: When the display case door needs to be closed, the movable plate 4 is pressed, causing the movable plate 4 to rotate and connect with the fixed plate 3 through the pivot. As the movable plate 4 continues to press down, the mounting plate 6 extends into the mounting groove 2. At the same time, the mounting plate 6 squeezes the roller 903. The movable rod 902 rotates with the fixed rod 901 through the pivot. Then, the spring 904 is stretched. The elastic property of the spring 904 is used to reduce the collision force when the roller 903 contacts the mounting plate 6.

[0037] During the closing of the cabinet door, as the mounting plate 6 continues to press down, the inclined surface of the bottom plate of the mounting plate 6 contacts the inclined surface of the tooth end of the locking tooth 802. Then, due to the squeezing force of the mounting plate 6, the locking tooth 802 rotates through the torque shaft 801. Then, due to the nature of the torque shaft 801, the locking tooth 802 engages with the locking groove 803. When it is necessary to open the cabinet door, the lever 804 is moved to drive the locking tooth 802 to rotate, thereby separating it from the locking groove 803, and then the movable plate 4 is lifted.

[0038] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
