[0022] like Figure 3As shown, the clamping member 42 includes a moving column 421, a clamping plate 422 and a first elastic member 423. The moving column 421 is inserted into the cylindrical sleeve 311. The moving direction of the moving column 421 is perpendicular to the extension direction of the axis of the cylindrical sleeve 311. The clamping plate 422 is arranged on the first end of the moving column 421 and is located in the cylindrical sleeve 311. The second end of the moving column 421 cooperates with the inner side wall of the threaded sleeve 411. The first elastic member 423 is sleeved on the moving column 421.

The first elastic member 423 applies a force to the clamping plate 422 in a direction away from the cylindrical sleeve 311. With the above structure, the movable column 421 is arranged to be movable in a direction perpendicular to the extending direction of the axis of the cylindrical sleeve 311, the clamping plate 422 is arranged on the first end of the movable column 421 and is located in the cylindrical sleeve 311, and the threaded sleeve 411 can cooperate with the second end of the movable column 421, so that when the threaded sleeve 411 moves upward, the movable column 421 can be driven to move toward the axis direction close to the cylindrical sleeve 311, so that the clamping plate 422 on the first end of the movable column 421 can clamp the connecting cable 3 2, and the first elastic member 423 is sleeved on the movable column 421, the first end of the first elastic member 423 is connected to the clamping plate 422, and the second end of the first elastic member 423 is connected to the inner wall of the cylindrical sleeve 311, and the first elastic member 423 applies a force to the clamping plate 422 in a direction away from the cylindrical sleeve 311, so that when the threaded sleeve 411 is separated from the cylindrical sleeve 311, it can ensure that the movable column 421 and the clamping plate 422 can be reset, thereby avoiding continuous clamping of the connecting cable 32.

[0023] like Figure 3 As shown, the inner wall of the threaded sleeve 411 has a threaded barrel section 4111 and a conical guide section 4112. The conical guide section 4112 is located above the threaded barrel section 4111. The internal thread is arranged on the threaded barrel section 4111. The transverse cross-sectional dimension of the conical guide section 4112 gradually decreases from top to bottom. The second end of the movable column 421 abuts against the conical guide section 4112. By adopting the above structure, the conical guide section 4112 is located above the threaded barrel section 4111, and the internal thread is set on the threaded barrel section 4111, so that when the threaded sleeve 411 is sleeved on the cylindrical sleeve 311, the internal thread of the threaded barrel section 4111 can be threadedly connected with the external thread of the outer wall of the cylindrical sleeve 311, and the transverse cross-sectional size of the conical guide section 4112 gradually decreases from top to bottom, so that when the conical guide section 4112 rotates and moves upward along the axis of the cylindrical sleeve 311, the inclined surface of the conical guide section 4112 abuts and cooperates with the second end of the movable column 421, thereby being able to push the movable column 421 to move and clamp the connecting cable 32.

The guide rod 424 can also guide the movement of the moving column 421, ensuring that the sliding clamping structure of the moving column 421 is more stable.

[0025] like Figure 3 As shown, a fixing block 312 is provided on the lower surface of the display member 31, and a bayonet 313 and a second elastic member 314 are provided in the fixing block 312.

[0026] like Figure 4As shown, the display device based on VR simulation imaging also includes a second driving member 51, a rotating rod 52, a lifting plate 53 and a connecting rod 54. The second driving member 51 is arranged in the fixed shell 21, and the rotating rod 52 is rotatably arranged in the fixed shell 21 along the height direction of the fixed shell 21. The driving shaft of the second driving member 51 is drivingly connected to the first end of the rotating rod 52 to drive the rotating rod 52 to rotate. The lifting plate 53 is provided with a threaded hole, and the rotating rod 52 has a threaded column section, which is penetrated by the threaded hole and threadedly connected with the threaded hole.

The above structure is adopted, by arranging a second driving member 51 and a rotating rod 52 in the fixed shell 21, the second driving member 51 is drivingly connected to the rotating rod 52, and thus the rotating rod 52 can be driven to rotate, a threaded hole is arranged on the lifting plate 53, and a threaded column section is arranged on the rotating rod 52, the rotating rod 52 is penetrated into the threaded hole and threadedly matched with the threaded hole, and the lifting plate 53 can be driven to rise or fall when the rotating rod 52 rotates. In addition, since the connecting rod 54 is arranged in the fixed shell 21, the first end of the connecting rod 54 is connected to the lifting plate 53, and the second end of the connecting rod 54 is connected to the top wall of the inner side wall of the lifting shell 22, when the lifting plate 53 moves, it can drive the connecting rod 54 to move up and down, and then the lifting shell 22 can be driven to rise or fall under the action of the connecting rod 54, so as to adjust the display member 31 on the lifting shell 22.

[0027] It should be noted that a ball bearing 533 is disposed on the side of the lifting plate 53, and the ball bearing 533 is slidably connected to the limiting groove of the inner wall of the fixed shell 21. By disposing the ball bearing 533, the relative friction between the lifting plate 53 and the fixed shell 21 can be reduced.

[0028] like Figure 4 and Figure 5As shown, an oil storage box 55 is provided at the second end of the rotating rod 52. The oil storage box 55 has a accommodating chamber 56. A sealing ring 57 and a closing plug 58 are provided in the accommodating chamber 56. The outer wall of the sealing ring 57 is fixedly sealed with the inner wall of the oil storage box 55 and divides the accommodating chamber 56 into a first cavity 561 and a second cavity 562. The first cavity 561 is used to accommodate lubricating oil. An oil leakage hole 551 connected to the second cavity 562 is provided at the bottom of the oil storage box 55. The closing plug 58 is movably provided at the inner hole of the sealing ring 57 in the vertical direction and has a blocking position and a connecting position. When the closing plug 58 is in the closing position, the outer wall of the closing plug 58 is sealed with the inner wall of the sealing ring 57 to isolate the first cavity 561 and the second cavity 562 from each other. When the closing plug 58 is in the connecting position, the first cavity 561 and the second cavity 562 are connected through the gap between the closing plug 58 and the sealing ring 57. A push rod 531 is provided on the lifting plate 53. When the lifting plate 53 moves upward and penetrates the oil leakage hole 551, the push rod 531 drives the closing plug 58 to move relative to the sealing ring 57 so that the closing plug 58 switches from the closing position to the connecting position. With the above structure, an oil storage box 55 is provided at the second end of the rotating rod 52, and a sealing ring 57 and a closing plug 58 are provided in the accommodating chamber 56 of the oil storage box 55. The outer wall of the sealing ring 57 is fixedly sealed with the inner wall of the oil storage box 55 and divides the accommodating chamber 56 into a first cavity 561 and a second cavity 562. The first cavity 561 is used to accommodate lubricating oil. The bottom of the oil storage box 55 is provided with an oil leakage hole 551 connected to the second cavity 562. The closing plug 58 can move so that when the lifting plate 53 is raised, the top rod 531 on the lifting plate 53 can be inserted into the oil leakage hole 551, so that the top rod 531 and the closing plug 58 can be connected. The plug 58 is driven to cooperate, thereby driving the closed plug 58 to move, so that there is a gap between the closed plug 58 and the sealing ring 57, and the first cavity 561 is connected with the second cavity 562 through the gap between the closed plug 58 and the sealing ring 57, so that the lubricating oil in the first cavity 561 can flow into the second cavity 562 through the gap between the closed plug 58 and the sealing ring 57. Since the oil leakage hole 551 at the bottom of the oil storage box 55 is connected with the second cavity 562, when the top rod 531 is separated from the oil leakage hole 551, the lubricating oil leaks out through the oil leakage hole 551, thereby ensuring the lubrication of the rotating rod 52.

The transverse cross-sectional size of the conical barrel section 581 gradually decreases from top to bottom, and the hole wall of the inner hole of the sealing ring 57 is a conical hole matched with the outer wall of the conical barrel section 581. With the above structure, the closed plug 58 has a conical barrel section 581 and an annular plate section 582, the conical barrel section 581 can be sealed with the hole wall of the inner hole of the sealing ring 57, and the annular plate section 582 is provided with a connecting hole 5821 to allow lubricating oil to flow from the connecting hole 5821 into the space between the annular plate section 582 and the sealing ring 57. When there is a gap between the closed plug 58 and the sealing ring 57, the lubricating oil can flow into the second cavity 562, so as to facilitate the use of the lubricating oil to lubricate the rotating rod 52.

[0030] It should be noted that the first cavity 561 has a sponge block containing lubricating oil. The sponge block is compressed by the closing plug 58 so that the lubricating oil in the sponge block flows into between the annular plate segment 582 and the sealing ring 57 through the connecting hole 5821. When there is a gap between the conical barrel segment 581 of the closing plug 58 and the hole wall of the inner hole of the sealing ring 57, the first cavity 561 and the second cavity 562 can be connected.

[0031] like Figure 5 and Figure 6 As shown, the closed plug 58 has a mounting groove 583, and the display device based on VR simulation imaging further includes a third elastic member 59, a first end of the third elastic member 59 is connected to the bottom wall of the oil storage box 55, and a second end of the third elastic member 59 is connected to the mounting groove 583.
