The other end of the limiting rope 5 is fixedly connected to a waist ring 6. The front end of the waist ring 6 is movably connected to a movable ring 7. The inner cavity of the waist ring 6 is provided with a limiting mechanism 8. The limiting mechanism 8 includes a first limiting block 801, a spring 802, a pressing block 803 and a second limiting block 804. The first limiting block 801 is movably connected to the inner cavity of the waist ring 6, and the top of the spring 802 is fixedly connected to the bottom end of the first limiting block 801. The pressing block 803 passes through from the top of the first limiting block 801 to the top of the waist ring 6, and the second limiting block 804 is fixedly connected to the right side of the movable ring 7.

[0023] refer to Figures 1 to 5The inner cavity of the threaded rotating rod 204 is meshedly connected with the surface of the threaded rotating rod 204. The number of height adjusting mechanisms 2 is at least three. The height adjusting mechanisms 2 are equidistantly arrayed on the outside of the top of the base 1. The bottom end of the spring 802 is fixedly connected to the bottom end of the inner cavity of the waist ring 6. The front end of the second limit block 804 is movably engaged with the rear end of the first limit block 801. A baffle 9 is fixedly connected to the outside of the top of the base 1, and an anti-slip pad 10 is provided at the bottom end of the base 1.

[0024] By adopting the above scheme: through the setting of the baffle 9, the legs and feet of the person can be protected to prevent the legs and feet of the person from walking outside the device during walking. Through the setting of the anti-slip pad 10, the friction force at the bottom of the base 1 can be increased to prevent the device from sliding during use.

[0025] refer to Figures 1 to 5 An inspection cover 11 is fixedly installed on the outer side of the base 1 by bolts, and a sealing strip is provided on the contact surface between the inspection cover 11 and the base 1. The surface of the threaded rotating rod 204 is fixedly sleeved with a bearing body 12, and the surface of the bearing body 12 is fixedly sleeved in the inner cavity of the fixed sleeve rod 201. The inner cavity of the fixed sleeve rod 201 is provided with a limiting groove 13, and the surface of the telescopic inner rod 202 is fixedly connected to the limiting strip 14, and the surface of the limiting strip 14 is movably connected to the inner cavity of the limiting groove 13.

[0026] By adopting the above scheme: through the setting of the inspection cover 11, the internal components of the base 1 can be inspected and replaced to avoid the impact of component damage on the operation of the device; through the setting of the bearing body 12, the surface wear of the threaded rotating rod 204 can be reduced to avoid its breakage during operation; through the setting of the limit groove 13 and the limit strip 14, the extension and retraction of the telescopic inner rod 202 can be limited to avoid its rotation during the extension and retraction process.

[0027] Working principle:

[0028] When in use, the various components of the device are operated and controlled through the PLC control panel, and the use height of the device is adjusted according to the height of the user, and the threaded rotating rod 204 is driven to rotate by controlling the driving motor 203, and the telescopic inner rod 202 is driven to be telescoped by the rotation of the threaded rotating rod 204, and the annular support frame 4 is driven to move by the movement of the telescopic inner rod 202, so as to adjust the use height of the device, and the first limit block 801 is driven to move downward by pressing the pressing block 803, so that the first limit block 801 loses the limit on the second limit block 804. At this time, the movable ring 7 is pulled outward to drive the second limit block 804 to move out of the inner cavity of the waist ring 6, and then the waist ring 6 is put on the waist of the user, and the second limit block 804 is driven to move into the inner cavity of the waist ring 6 by pressing the movable ring 7 inward, and the first limit block 801 is driven to move downward. The limit block 801 applies the following pressure to move the first limit block 801 downward, and the movement of the first limit block 801 drives the spring 802 to contract. When the front end of the second limit block 804 moves to the rear end of the first limit block 801, the rebound characteristic of the spring 802 pushes the first limit block 801 to move upward to limit the second limit block 804, so that the movable ring 7 is connected to the waist ring 6, so that the waist ring 6 is worn around the waist of the user, and the user wears VR glasses and steps on the top of the movable ball 3. When the user moves, the movable ball 3 rotates inside the base 1, so that the user can walk on the surface of the movable ball 3 when walking on the upper end of the base 1, and the waist ring 6 is pulled and limited by the limiting rope 5, so that the user will not move out of the use range of the device.

[0029] In summary: This interactive VR teaching and protection device, through the coordinated use of various components, solves the problem that in the actual use of existing equipment, the user is prone to walk out of the range of use of the equipment when walking, and the user wearing VR glasses cannot distinguish the real situation, which may cause the user to fall and get injured.
