Description

Technical Field

[0001] This invention relates to the field of cultural relic display technology, and in particular to a rotating display case for easy viewing of cultural relics. Background Technology

[0002] A cultural relic display case is a type of cabinet used to store and display cultural relics. It is commonly found in museums, art galleries, and other similar places.

[0003] Patent publication number CN112932206A discloses a rotating artifact display case for convenient viewing. This rotating artifact display case includes: a base plate; a cabinet body mounted on the base plate; a tabletop mounted on the cabinet body; a first guide frame mounted on the cabinet body; a first sliding frame slidably mounted on the first guide frame; and a first spring mounted between the first sliding frame and the first guide frame. While this rotating artifact display case can rotate and display artifacts, the angle and direction of rotation are fixed and cannot be freely adjusted as needed, making it inconvenient for careful viewing.

[0004] Therefore, we propose a rotating display case for easy viewing of cultural relics that can be freely adjusted. Summary of the Invention

[0005] To overcome the shortcomings of existing rotating artifact display cases where the rotation direction and angle of artifacts cannot be adjusted, this invention provides a rotating artifact display case that allows for convenient viewing by rotating at any angle.

[0006] A rotating artifact display case for easy viewing includes a mounting base, a protective cover, a lifting cylinder, a drive motor, a pinion, a rotating shaft, a large gear, a mounting sleeve, a placement ring, a lifting mechanism, and a rotating mechanism. The protective cover is connected inside the mounting base, and the lifting cylinder is slidably connected inside the protective cover. The drive motor is connected to the lower right side of the lifting cylinder, and a pinion is connected to the output shaft of the drive motor. A rotating shaft is rotatably connected to the center of the lifting cylinder, and a large gear is connected to the lower part of the rotating shaft. The large gear meshes with the pinion. The mounting sleeve is connected to the upper part of the rotating shaft, and a placement ring is slidably connected inside the mounting sleeve. The lower part of the protective cover is equipped with a lifting mechanism for controlling the lifting of the lifting cylinder, and the upper part of the protective cover is equipped with a rotating mechanism for adjusting the angle of the artifact.

[0007] Optionally, the lifting mechanism includes a mounting shell, a mounting bracket, a turntable, a slide rail, and a locking assembly. The mounting shell is connected to the lower front side of the protective cover, the mounting bracket is connected to the mounting shell, the turntable is rotatably connected inside the mounting bracket, the slide rail is slidably connected to the mounting shell, the rear of the slide rail is connected to the lifting cylinder, the rear of the turntable extends into the slide rail, and the turntable is provided with a locking assembly for fixing the angle of the turntable.

[0008] Optionally, the positioning assembly includes a guide block, a locking block, and a first spring. Guide blocks are connected to both the upper and lower parts of the front side of the turntable, and locking blocks are slidably connected inside each guide block. The locking blocks are locked into the mounting bracket, and a first spring is connected between each locking block and the adjacent guide block.

[0009] Optionally, the rotating mechanism includes a mounting plate, an L-shaped plate, a rotating frame, a second spring, a first rubber wheel, a turbine, and a worm gear. Mounting plates are connected to both the upper left and right sides of the protective cover. L-shaped plates are slidably connected to both the upper left and right sides of the protective cover. The lifting cylinder slides upward and contacts the L-shaped plate. Rotating frames are rotatably connected to each mounting plate. Each mounting plate slides upward and contacts the adjacent rotating frame. A second spring is connected between each rotating frame and the adjacent mounting plate. A first rubber wheel is rotatably connected to the upper part of each rotating frame. A turbine is connected to the front of the first rubber wheel on the left. A worm gear is rotatably connected to the upper left part of the protective cover. After the turbine moves downward, it meshes with the worm gear.

[0010] Optionally, it also includes a support mechanism for supporting the cultural relic. The support mechanism includes an inclined plate, a crossbar, a support ring, a second rubber wheel, and a third spring. An inclined plate is connected to the upper left side inside the protective cover, and a crossbar is connected to the rear left side of the placement ring. The crossbar moves upward and contacts the inclined plate. A support ring is connected inside the mounting cylinder. Several second rubber wheels are rotatably connected to the front of the support ring. A third spring is connected between the placement ring and the mounting cylinder.

[0011] Optionally, it also includes a limiting mechanism for limiting the cultural relic. The limiting mechanism includes a guide plate, a limiting block and a fourth spring. Several guide plates are connected to the front inner side of the front part of the support ring. Each guide plate is slidably connected to a limiting block, and a fourth spring is connected between the limiting block and the adjacent guide plate.

[0012] Optionally, it also includes a lighting mechanism for providing illumination for viewing the artifact. The lighting mechanism includes a sliding plate, a light shield, a lighting rod, a torsion spring, and a pressure plate. The sliding plate is slidably connected to the upper part of the protective cover. The light shield is connected inside the mounting cylinder. The lighting rod is rotatably connected inside the mounting cylinder. A torsion spring is connected between the lighting rod and the mounting cylinder. The pressure plate is slidably connected to the upper rear part of the mounting cylinder. The pressure plate slides downward and contacts the rear part of the lighting rod.

[0013] Optionally, the outer ends of the limit blocks are all inclined.

[0014] The present invention has the following advantages: 1. During the display, the drive motor rotates to make the placement ring rotate, thereby causing the cultural relic to rotate for display. When it is necessary to view the cultural relic up close, the turntable rotates and the slide rail can make the lifting cylinder rise, thereby causing the cultural relic to move upward and close to the top wall of the protective cover. After the first rubber wheel moves downward and contacts the cultural relic, the turbine and worm gear can make the first rubber wheel rotate, thereby causing the cultural relic to rotate on the placement ring and change its angle so that the staff can view it carefully.

[0015] 2. After the artifact is placed on the placement ring, the second rubber wheel contacts the inner wall of the artifact. When the staff rotates the artifact to adjust the viewing angle, the second rubber wheel can support the artifact while reducing the friction of the artifact's rotation.

[0016] 3. After the artifact is placed on the placement ring, the limiting block slides outward and opens, limiting the artifact and ensuring its stability.

[0017] 4. The light stick provides illumination for viewing cultural relics. When the light stick is rotated, it will be blocked by the light shield and stop the illumination. Staff can adjust it as needed. Attached Figure Description

Detailed Implementation

[0033] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] Example 1

[0035] A rotating display case for easy viewing of cultural relics, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a mounting base 1, a protective cover 2, a lifting cylinder 3, a drive motor 4, a pinion 5, a rotating shaft 6, a large gear 7, a mounting cylinder 8, a placement ring 9, a lifting mechanism 10, and a rotating mechanism 11. The protective cover 2 is connected inside the mounting base 1. The lifting cylinder 3 is slidably connected inside the protective cover 2. The drive motor 4 is bolted to the lower right side of the lifting cylinder 3. The pinion 5 is keyed to the output shaft of the drive motor 4. The rotating shaft 6 is connected to the center of the lifting cylinder 3 via a bearing. The large gear 7 is keyed to the lower part of the rotating shaft 6. The large gear 7 meshes with the pinion 5. The mounting cylinder 8 is connected to the upper part of the rotating shaft 6. The placement ring 9 is slidably connected inside the mounting cylinder 8. The lifting mechanism 10 is provided at the lower part of the protective cover 2. The lifting mechanism 10 can control the lifting of the lifting cylinder 3. The rotating mechanism 11 is provided at the upper part of the protective cover 2. The rotating mechanism 11 can adjust the angle of the artifact.

[0036] When using this device, staff place the artifact on the placement ring 9 and cover it with the protective cover 2. During display, staff start the drive motor 4. The output shaft of the drive motor 4 rotates, driving the small gear 5 to rotate. The small gear 5 rotates, driving the large gear 7 to rotate. The large gear 7 rotates, driving the mounting cylinder 8 to rotate via the rotating shaft 6. The mounting cylinder 8 rotates, driving the placement ring 9 to rotate, thus rotating the artifact for display. When closer observation of the artifact is needed, staff control the lifting cylinder 3 to rise using the lifting mechanism 10. The upward movement of the lifting cylinder 3 drives the rotating shaft 6, the large gear 7, the mounting cylinder 8, and the placement ring 9 to move upward. After the large gear 7 moves upward, it disengages from the small gear 5 and stops rotating. The upward movement of the placement ring 9 moves the artifact upward, bringing it closer to the top wall of the protective cover 2. Then, staff control the artifact to rotate freely using the rotating mechanism 11, allowing staff to observe the artifact's various positions. After the device is used, staff turn off the drive motor 4.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the lifting mechanism 10 includes a mounting shell 101, a mounting bracket 102, a turntable 103, a slide rail 104, a guide block 105, a locking block 106, and a first spring 107. The mounting shell 101 is bolted to the lower front side of the protective cover 2. The mounting bracket 102 is bolted to the mounting shell 101. The turntable 103 is rotatably connected inside the mounting bracket 102. The slide rail 104 is slidably connected to the mounting shell 101. The rear part of the slide rail 104 is connected to the lifting cylinder 3. The rear part of the turntable 103 extends into the slide rail 104. Guide blocks 105 are welded to the upper and lower parts of the front side of the turntable 103. Locking blocks 106 are slidably connected inside the guide blocks 105. The locking blocks 106 are locked into the mounting bracket 102. The locking blocks 106 and the adjacent guide blocks 105 are connected by the first spring 107.

[0038] When close viewing of the artifact is required, staff rotate turntable 103. The rotation of turntable 103 causes slide rail 104 to slide upward, which in turn lifts the lifting cylinder 3, thereby moving the artifact upward. While staff are viewing the artifact closely, the rotation of turntable 103 also causes guide block 105 to rotate the locking block 106. The locking block 106 is squeezed inward by mounting frame 102, causing the first spring 107 to deform. When the locking block 106 rotates to engage with mounting frame 102, under the reset action of the first spring 107, the locking block 106 slides outward and engages with mounting frame 102, thereby fixing the position of lifting cylinder 3 and keeping the artifact in a raised state. After viewing is completed, staff control turntable 103 to reverse, which causes the lifting cylinder 3 to slide downward and reset via slide rail 104.

[0039] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the rotating mechanism 11 includes a mounting plate 111, an L-shaped plate 112, a rotating frame 113, a second spring 114, a first rubber wheel 115, a turbine 116, and a worm gear 117. Mounting plates 111 are bolted to the upper left and right sides of the inner part of the protective cover 2. L-shaped plates 112 are slidably connected to the upper left and right sides of the inner part of the protective cover 2. The lifting cylinder 3 slides upward to push the L-shaped plates 112 upward. The rotating frame 113 is connected to the mounting plate 111 through bearings. The mounting plate 111 slides upward to press the adjacent rotating frame 113 to rotate. The second spring 114 is connected between the rotating frame 113 and the adjacent mounting plate 111. The upper part of the rotating frame 113 is connected to the first rubber wheel 115 through bearings. The front part of the first rubber wheel 115 on the left is keyed to the turbine 116. The upper left part of the protective cover 2 is connected to the worm gear 117 through bearings. After the turbine 116 moves downward, it meshes with the worm gear 117.

[0040] When using this device, when the lifting cylinder 3 slides upward to contact the L-shaped plate 112, the lifting cylinder 3 continues to move upward, pushing the L-shaped plate 112 to slide upward. The L-shaped plate 112 slides upward, squeezing the rotating frame 113 to rotate downward. The second spring 114 deforms, and the rotating frame 113 rotates downward, causing the first rubber wheel 115 to move downward and contact the artifact. The first rubber wheel 115 moves downward, causing the turbine 116 to move downward and engage with the worm gear 117. At this time, the staff can rotate the worm gear 117 outside the protective cover 2. The rotation of the worm gear 117 drives the turbine 116 to rotate, and the rotation of the turbine 116 drives the first rubber wheel 115 to rotate, thereby causing the artifact to rotate on the placement ring 9 and change its angle so that the staff can observe it carefully. After the observation is completed, the lifting cylinder 3 slides downward and no longer squeezes the L-shaped plate 112. At this time, under the action of the second spring 114 resetting, the rotating frame 113 drives the first rubber wheel 115 to move upward and detach from the artifact.

[0041] Example 2

[0042] Based on Example 1, such as Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, it also includes a support mechanism 12, which can support the cultural relic. The support mechanism 12 includes an inclined plate 121, a crossbar 122, a support ring 123, a second rubber wheel 124, and a third spring 125. An inclined plate 121 is welded to the upper left side inside the protective cover 2. A crossbar 122 is welded to the rear left side of the placement ring 9. The crossbar 122 moves upward and is squeezed backward by the inclined plate 121. A support ring 123 is bolted inside the mounting cylinder 8. Three second rubber wheels 124 are connected to the front of the support ring 123 through bearings. The third spring 125 is connected between the placement ring 9 and the mounting cylinder 8.

[0043] When using this device, when the artifact is placed on the placement ring 9, the second rubber wheel 124 contacts the inner wall of the artifact. When the placement ring 9 moves upward, it will drive the horizontal bar 122 to move upward. When the horizontal bar 122 moves upward to contact the inclined plate 121, the horizontal bar 122 continues to move upward and will be squeezed backward by the inclined plate 121. The backward movement of the horizontal bar 122 drives the placement ring 9 to slide backward, and the third spring 125 deforms. At this time, the artifact is supported by the second rubber wheel 124. When the staff controls the rotation of the artifact to adjust the viewing angle, the second rubber wheel 124 can reduce the friction of the artifact's rotation while supporting the artifact. After the artifact is viewed, the placement ring 9 moves downward, driving the horizontal bar 122 to move downward. After the horizontal bar 122 moves downward, it no longer squeezes the inclined plate 121. At this time, under the action of the third spring 125 resetting, the placement ring 9 slides forward and resets.

[0044] like Figure 2 and Figure 12 As shown, it also includes a limiting mechanism 13, which can limit the cultural relic. The limiting mechanism 13 includes a guide plate 131, a limiting block 132 and a fourth spring 133. Three guide plates 131 are welded to the front inner side of the support ring 123. Each guide plate 131 is slidably connected to a limiting block 132 for limiting the cultural relic. The outer ends of the limiting blocks 132 are all inclined. A fourth spring 133 is connected between each limiting block 132 and the adjacent guide plate 131.

[0045] When placing the cultural relic, the staff controls the limiting block 132 to slide inward and retract on the guide plate 131, causing the fourth spring 133 to deform. Then, the staff places the cultural relic on the placement ring 9. After placement, the staff releases the limiting block 132. Under the action of the fourth spring 133 resetting, the limiting block 132 slides outward and opens. The limiting block 132 limits the placement of the cultural relic, ensuring its stability.

[0046] like Figure 1 , Figure 2 , Figure 13 and Figure 14As shown, it also includes a lighting mechanism 14, which can provide lighting for viewing cultural relics. The lighting mechanism 14 includes a sliding plate 141, a light shield 142, a lighting rod 143, a torsion spring 144, and a lower pressure plate 145. The sliding plate 141 is slidably connected to the upper part of the protective cover 2. The light shield 142 is welded inside the mounting cylinder 8. The lighting rod 143 is rotatably connected inside the mounting cylinder 8. The torsion spring 144 is connected between the lighting rod 143 and the mounting cylinder 8. The lower pressure plate 145 is slidably connected to the upper rear part of the mounting cylinder 8. The lower pressure plate 145 slides downward to push the lighting rod 143 to rotate.

[0047] When using the device, the lighting rod 143 provides illumination for viewing the artifacts. When the mounting cylinder 8 moves upward, the lower pressure plate 145 also moves upward. When staff are viewing the artifacts at close range, if the lighting rod 143 is not needed, the staff can push the sliding plate 141 downward. The sliding plate 141 slides downward, pressing the lower pressure plate 145 downward. The lower pressure plate 145 slides downward, pressing the lighting rod 143 to rotate. The torsion spring 144 deforms, and after the lighting rod 143 rotates, it is blocked by the light shield 142 to stop the illumination, preventing the light from affecting the staff's viewing. After viewing, the staff releases the sliding plate 141. Under the action of the torsion spring 144 resetting, the lighting rod 143 reverses and resets, no longer blocked by the light shield 142. At this time, the light shield 142 provides normal illumination.
