A rotary base 3 is rotatably provided on the top of the base 1. Side plates 4 are welded on the outer walls on both sides of the top of the rotary base 3. A first lifting platform 10 is slidably provided above the side plates 4. A first motor 13 is provided on the outer wall of the top of the rotary base 3, and a swing rod 14 is installed on the output shaft of the first motor 13. A connecting rod 16 is provided at the end of the swing rod 14 through a pin shaft 15. The top end of the connecting rod 16 is rotatably connected to a first hinge seat 17 installed on the bottom outer wall of the first lifting platform 10. A second motor 18 is provided on the outer wall of one side of the top of the first lifting platform 10, and a lead screw 20 is installed on the output shaft of the second motor 18. A bearing seat 19 installed on both sides of the top of the first lifting platform 10 is sleeved outside the lead screw 20. A threaded sleeve 21 is threadedly sleeved outside the lead screw 20. The upper part of the threaded sleeve 21 is rotatably connected to a movable support rod 22, and the top end of the movable support rod 22 is provided with a second hinge seat 23. A second lifting platform 6 is fixedly provided on the top of the two second hinge seats 23. A plurality of liftable stabilizing rods 24 are provided between the second lifting platform 6 and the first lifting platform 10.

[0028] Specifically, in this embodiment, it includes a base 1. A rotating seat 3 is rotatably arranged on the top of the base 1. A shallow groove is provided on the top of the base 1. At the same time, a bearing can also be arranged inside the shallow groove, and then the rotating seat 3 is installed inside the shallow groove on the base 1 through the bearing, enabling the rotating seat 3 to rotate above the base 1 to achieve the adjustment of the scanner angle. Side plates 4 are welded on the outer walls on both sides of the top of the rotating seat 3. The two side plates 4 are symmetrical arc-shaped structures. An elevating platform one 10 is slidably arranged above the side plates 4. The elevating platform one 10 covers the side plates 4, and at the same time, the elevating platform one 10 can freely move up and down. A motor one 13 is arranged on the outer wall of the top of the rotating seat 3, and a swing rod 14 is installed on the output shaft of the motor one 13. A connecting rod 16 is arranged at the end of the swing rod 14 through a pin shaft 15. The top end of the connecting rod 16 is rotatably connected to a hinge seat one 17 installed on the bottom outer wall of the elevating platform one 10. The operator starts the motor one 13, and the motor one 13 drives the swing rod 14 to rotate, so that the swing rod 14 drives the connecting rod 16 to move through the pin shaft 15, and finally drives the elevating platform one 10 to move up and down. A motor two 18 is arranged on the outer wall of one side of the top of the elevating platform one 10, and a lead screw 20 is installed on the output shaft of the motor two 18. The outside of the lead screw 20 is sleeved with bearing seats 19 installed on both sides of the top of the elevating platform one 10. A threaded sleeve 21 is threadedly sleeved on the outside of the lead screw 20. Here, the lead screw 20 is divided into two sections, and the thread directions of the two sections of the lead screw 20 are opposite. When the lead screw 20 rotates, it can drive the two threaded sleeves 21 outside it to move towards and away from each other. The upper part of the threaded sleeve 21 is rotatably connected to a movable support rod 22, and a hinge seat two 23 is arranged at the top end of the movable support rod 22. The top parts of the two hinge seats two 23 are fixedly provided with an elevating platform two 6. The operator starts the motor two 18, and the motor two 18 drives the lead screw 20 to rotate. Under the action of the lead screw 20 and the threaded sleeve 21, the movable support rod 22 is driven to change the angle, so as to adjust the height of the elevating platform two 6. A number of liftable stabilizing rods 24 are arranged between the elevating platform two 6 and the elevating platform one 10. The stabilizing rods 24 adopted are liftable type, which play a guiding and stabilizing role when adjusting the height of the elevating platform two 6, ensuring the stability of the overall lifting structure.

[0029] For the lifting structure for a three-dimensional scanner provided by the present utility model, the motor one 13 drives the elevating platform one 10 and the motor two 18 drives the elevating platform two 6 to perform lifting movements. The elevating platform one 10 or the elevating platform two 6 can be controlled separately to lift, or both of them can be controlled to lift simultaneously, improving the efficiency of lifting the scanner above and also improving the working efficiency of the scanner.

[0030] As an embodiment provided by the present utility model, a number of legs 2 are welded on the outer wall of the bottom of the base 1, and a foot pad is welded at the bottom end of the legs 2. The legs 2 and the foot pads adopted ensure the stability of the placement of the base 1 and also improve the stability when adjusting the height of the scanner.

Sliding grooves 12 which are slidably connected with the guide rods 11 are arranged on the inner walls of both sides of the side plate 4. When the first lifting platform 10 is lifted or lowered, since the guide rods 11 are fixed on the outer wall at the bottom of the first lifting platform 10, the first lifting platform 10 drives the guide rods 11 to slide inside the sliding grooves 12, ensuring the motion accuracy when the first lifting platform 10 is lifted or lowered.

[0033] In one embodiment provided by the present utility model, the second lifting platform 6 has an inverted cylindrical structure, and the lower part of the second lifting platform 6 is sleeved outside the side plate 4 and the first lifting platform 10. By adopting the second lifting platform 6 with a cylindrical structure, it can be sleeved outside the side plate 4 and the first lifting platform 10, making the overall lifting structure have better integrity.

[0034] In another embodiment provided by the present utility model, a storage box 7 is fixedly arranged on the top of the second lifting platform 6, and a storage component 8 located inside the storage box 7 is installed on the top of the second lifting platform 6. One end of the storage component 8 is provided with a scanner body 9. The storage component 8 can be used to store the scanner body 9 inside the storage box 7, achieving a better protection effect on the scanner.

[0035] The storage component 8 includes a slide rail 27 fixed on the outer wall at the top of the second lifting platform 6. A slide seat 28 is slidably installed on the slide rail 27. A lifting sleeve rod 29 is fixedly arranged on the outer wall at the top of the slide seat 28. A support arm 30 is fixedly installed on one side of the lifting sleeve rod 29. The scanner body 9 is installed on the outer wall at one end of the support arm 30. When the operator uses the scanner, the height of the scanner can be adjusted to be higher than the position of the storage box 7 through the lifting sleeve rod 29, and the position of the scanner can be adjusted by sliding the slide seat 28 on the slide rail 27, making the scanner completely extend out of the storage box 7, so as to better realize the scanning operation. After the scanner finishes working, through the movement of the lifting sleeve rod 29 and the slide seat 28 on the slide rail 27, the scanner body 9 is stored inside the storage box 7, achieving better protection for the scanner.

[0036] In another embodiment provided by the present utility model, a through hole is provided on the outer wall of the bottom of the base 1, and a transmission shaft connected to the rotating base 3 is inserted into the through hole. A driven gear 25 is installed at the bottom end of the transmission shaft. A driving gear 26 meshing with the driven gear 25 is provided on the outer wall of one side of the bottom of the base 1. The driving gear 26 is a structure composed of a motor and a gear. The rotation of the driving gear 26 drives the driven gear 25 to rotate, and then the rotating base 3 is driven to rotate above the base 1 through the transmission shaft, so as to realize the angle adjustment of the upper components.

[0037] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways.
