Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses a 3D display device in a holographic projection exhibition room. As shown in figure 1, a 3D display device in holographic projection exhibition room, including a supporting bench 1, show cupboard 2 is installed to the upside of a supporting bench 1, and supporting legs 3 are installed to the downside of a supporting bench 1, and supporting legs 3 are the annular setting and support subaerial, have guaranteed the stability of show cupboard 2.

The inboard of supporting legs 3 is equipped with four dwang 11, and dwang 11 rotates to be connected in the downside that props up a supporting bench 1, and the plane that dwang 11 formed when rotating is on a parallel with vertical face, and gyro wheel 12 is installed to the lower extreme of dwang 11, and the lateral part of dwang 11 is connected with support column 13, and a plurality of friction strips 131 are installed to the lower extreme of support column 13. In the display process of the display cabinet 2, the supporting legs 3 are supported on the ground, and the rotating rod 11 causes the rollers 12 and all the friction strips 131 to abut against the ground due to the self gravity, so that the stability of the display cabinet 2 is improved.

A clamping groove 111 is formed in the side wall of the rotating rod 11, and a notch of the clamping groove 111 is arranged upwards; a plurality of handles 14 are arranged on the side wall of the supporting table 1, a plurality of limiting plates 15 which are obliquely arranged and a plurality of penetrating rods 16 which are vertically arranged are arranged on the lower surface of the supporting table 1, the same limiting ring 17 penetrates through all the penetrating rods 16, and the limiting rings 17 are used for being clamped in all the clamping grooves 111; the outer wall of the limiting ring 17 is connected with a pedal 19 through a connecting rod 18, the connecting rod 18 penetrates through the supporting leg 3 in a sliding mode along the vertical direction, and the pedal 19 is located on the outer side of the supporting leg 3.

When the display cabinet 2 needs to be carried, a worker lifts the support table 1 through the lifting handle 14, the rotating rod 11 is turned downwards due to the self gravity, so that the roller 12 rolls on the ground, and the rubbing strip 131 is separated from the ground; when dwang 11 rotates to laminate in limiting plate 15, joint groove 111 will be vertical setting, and stop collar 17 will follow the joint in all joint grooves 111 that wears to establish 16 axial glides of pole because of self gravity this moment for all dwang 11 are by spacing fixed, and gyro wheel 12 will steadily support subaerial this moment, have made things convenient for the transport of show cupboard 2 in the exhibition room.

It should be noted that, because the rotating rod 11 and the roller 12 are both located at the inner side of the supporting foot 3, the rotating rod 11 and the roller 12 are not easily touched when the worker pushes the display cabinet 2 to move.

The lower surface of supporting legs 3 is equipped with a plurality of recesses 31, and the vertical direction slip is inlayed in recess 31 and is equipped with buffer plate 32, and buffer plate 32 passes through spring 33 and connects in the groove wall of recess 31. During the movement of the display cabinet 2, when the spring 33 is in a natural state, the lower surface of the buffer plate 32 is lower than the supporting legs 3; after the show cupboard 2 removed appointed position, the workman will be with the instep running-board of going up with the hook for spacing ring 17 slides and breaks away from in joint groove 111, and brace table 1 and show cupboard 2 will descend because of self gravity this moment, and dwang 11 and gyro wheel 12 will upwards overturn, and buffer board 32 will contradict in ground and make spring 33 compressed gradually, has reduced the falling speed of brace table 1 and show cupboard 2, makes show cupboard 2 be difficult for damaging because of vibrations.

The implementation principle of the 3D display device in the holographic projection exhibition room in the embodiment of the application is as follows: when the show cupboard 2 needs to be carried, the workman will lift a supporting bench 1 through handle 14, dwang 11 will overturn the laminating downwards in limiting plate 15, spacing ring 17 because of self gravity with the gliding joint in all joint grooves 111 for all dwang 11 are by spacing fixed, and gyro wheel 12 will steadily support subaerial this moment, have made things convenient for the transport of show cupboard 2 in the exhibition room.

After the display cabinet 2 moves to a designated position, a worker hooks the pedal plate on the instep to enable the limiting ring 17 to be separated from the clamping groove 111 in a sliding mode, at the moment, the support table 1 and the display cabinet 2 descend due to self gravity, the rotating rod 11 and the roller 12 turn upwards, the buffer plate 32 abuts against the ground and enables the spring 33 to be gradually compressed, and descending speed of the support table 1 and the display cabinet 2 is reduced; then, the supporting legs 3, the buffer plate 32, the rollers 12 and the rubbing strips 131 will be supported on the ground, which improves the stability of the display case 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
