Description

Technical Field

[0001] This invention relates to transmission mechanism manufacturing technology, and more particularly to a zipper-type chain opening device for a cultural relic display case, belonging to the field of opening and closing mechanism manufacturing technology. Background Technology

[0002] Currently, the main opening methods for museum artifact display cases are gas spring mechanisms and electric push rod mechanisms. These opening methods require sufficient installation space under the display stand. However, some exhibits cannot meet these requirements when on display, and the museum is forced to be unable to display such artifacts. This has a significant impact on visitors' understanding of the relevant historical atmosphere and background, thus affecting the viewing experience.

[0003] In existing technologies, the main opening methods for museum artifact display cases are gas spring mechanisms and electric push rod mechanisms. These methods require sufficient space for cylinder installation under the display stand. However, due to limited display height, and the fact that some exhibits require a greater display space, the existing methods cannot meet these needs.

[0004] Therefore, there is an urgent need in the existing technology for an artifact display case opening device that has a small installation space, stable operation, long lifting distance, large lifting weight, and low installation difficulty. Summary of the Invention

[0026] The zipper-type chain opening device for the cultural relic display case described in this invention can be made of the following materials and components, but is not limited to the following materials and components, such as: chain, sprocket, housing, servo motor, drive shaft, reducer, etc.

[0027] like Figure 1 The image shown is a side view of the zipper-type chain opening device for a cultural relic display case according to an embodiment of the present invention; combined with Figures 2 to 7 .

[0028] The zipper-type chain opening device for the artifact display case in this embodiment includes: a housing 2, a sprocket 3, a servo motor 1, and two chains 4; the housing 2 is a strip-shaped cavity structure, and the two chains 4 are slidably installed inside the housing 2; the housing 2 is generally made of steel square tubing.

[0029] The housing 2 has an opening in the middle, and the sprocket 3 is fixed to the opening; the two chains 4 turn and mesh with each other at the opening; the sprocket 3 meshes with one of the chains 4 at the opening; the sprocket 3 rotates to drive one of the chains 4 to slide inside the housing 2; the chain 4 turns at a right angle at the opening, and the sprocket 3 can obtain more contact and force points with the chain 4 at the turning point, which not only makes the transmission smoother, but also makes it easier to turn.

[0030] The servo motor 1 is fixed to the outside of the housing 2; the servo motor 1 has a drive shaft 10, which is connected to the sprocket 3.

[0031] Specifically, a steering groove 20 is provided inside the housing 2, and the steering groove 20 is located at the opening; the steering groove 20 is perpendicular to the length direction of the housing 2; the two sides of the steering groove 20 respectively contact the two chains 3. The steering groove 20 is used to limit the distance between the two chains 4, and plays a role in forcibly engaging the two chains, so that the two chains form a zipper-like structure.

[0032] like Figures 5 to 7 As shown; each chain 4 includes: multiple outer chain pieces 41, multiple inner chain pieces 42, and multiple connecting posts; two adjacent outer chain pieces 41 are connected by one inner chain piece 42; each inner chain piece 42 has a connecting post installed at both ends, and two adjacent outer chain pieces 41 are hinged to each other through the connecting post; the outer chain pieces 41 and the inner chain pieces 42 generally have the same shape and can mesh with each other, and their meshing shapes correspond to each other.

[0033] Furthermore, the sprocket 3 is in contact with the connecting post; the connecting posts are all located on the non-engaging side of the outer chain piece 41. This ensures that a single chain 4 bends in only one direction, thereby ensuring the overall stability of the chain opening device. It also ensures that the two chains abut against each other and are subjected to uniform force during engagement, making them less prone to deformation or deflection in either direction.

[0034] like Figure 7 As shown, in the two chains 4, one chain 4 engages with the inner chain piece 42 of the other chain via its outer chain piece 41. The two chains 4 are arranged in a staggered manner to achieve the effect of mutual restraint and engagement.

[0035] In this embodiment of the invention, the opening and closing of the artifact display case is achieved through the transmission structure of sprockets and chains. The two meshing chains play a supporting role for each other. The opening device of the present invention not only occupies a small volume, but also enables opening and lifting at ultra-high distances.

[0036] The artifact display case in this embodiment uses a zipper-type chain opening device, and an installation plate 12 is fixed to the outside of the right-angle bend; the servo motor 1 is fixed to the housing 2 through the installation plate 12.

[0037] Preferably, the opening device in this embodiment further includes: a reducer 11; the servo motor 1 has an output shaft, and the servo motor 1 is connected to the reducer 11 through the output shaft; the reducer 11 is fixed to the outside of the housing 2;

[0038] One end of the drive shaft 10 is connected to the reducer 11, and the other end is connected to the sprocket 3.

[0039] Typically, a flange plate 40 is provided on one end of the chain 4. The flange plate 40 is used to connect to external equipment, thereby facilitating the opening and closing of the cabinet.

[0040] Normally, a bushing 13 is provided on the mounting plate 12, and the drive shaft 10 is mounted on the mounting plate 12 through the bushing 13, thereby ensuring the stable operation of the sprocket 3.

[0041] The advantages of the zipper-type chain opening device for the artifact display case according to the embodiments of the present invention are as follows:

[0042] The flange support plate is connected to the upper frame of the display case, and the transmission mechanism is fixed to the ground or the bottom of the case. The servo motor drives the sprocket through a reducer, which in turn drives the chain. The two chains mesh with each other and move upward synchronously under the constraint of the steering slide. The flange support plate rises accordingly, and the servo motor stops and locks after reaching the set height. When the upper frame descends, the servo motor runs in reverse, dragging the rigid chain back to the chain bin. After reaching the set position, the motor stops and locks.

[0043] In addition, the zipper-type chain opening device for the artifact display case of the present invention has low manufacturing cost, is small and exquisite, has a compact structural design, stable finished product quality, occupies little space, has a high lifting height, and is suitable for opening and closing various modified large display cases.
