[0020] 3. The present invention drives the first slide and the second slide to slide on the inner surfaces of the third groove and the fourth groove respectively by extending and shortening the two second electric telescopic rods, so as to adjust the position of the limit block.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 7As shown, a lifting and installation device for large exhibits of industrial design comprises two L-shaped plates 1, one side of the L-shaped plates 1 is provided with a first groove 11, a top plate 2 is fixedly installed on the top of the two L-shaped plates 1, two support frames 22 are fixedly installed on the top of the top plate 2, a second groove 21 is provided on the top of the top plate 2, a wire winding column 4 is rotatably installed on the opposite surfaces of the two support frames 22, a wire 42 is wound around the outer surface of the wire winding column 4, one end of the wire 42 is fixedly connected with a hook 44, and two rollers 15 are rotatably installed on the bottom of the two L-shaped plates 1; a protection mechanism is also included to prevent the exhibits from being transported when large exhibits are transported. Shaking; the protection mechanism includes two first electric telescopic rods 13, both of which are fixedly installed on the bottom of the top plate 2, a fixed block 14 is fixedly installed on the outer surface of the first electric telescopic rod 13, and the fixed block 14 is fixedly installed on one side of the L-shaped plate 1, and the output end of the first electric telescopic rod 13 is fixedly connected with a slider 12, and the slider 12 is slidably installed on the inner surface of the first groove 11, a threaded rod 32 is threadedly installed on one side of the slider 12, and one end of the threaded rod 32 is fixedly connected to a clamping block 36, and a sliding rod 3 is slidably installed on one side of the slider 12, and one end of the sliding rod 3 is fixedly connected to a clamping block 36.

[0032] When large exhibits are moved and installed, they will shake during the movement due to their large size. The shaking of the exhibits may easily collide with the exhibit moving device and thus cause damage to the exhibits.

[0033] When the present invention is in use, the exhibit lifting and installation device is first connected to the exhibit through the hook 44, and then the hook 44 is lifted by tightening the wire 42 through the wire winding column 4, so as to achieve the lifting of the exhibit, and then the two clamping blocks 36 can be driven to approach each other by rotating the threaded rod 32 to cooperate with the limit of the slide rod 3 to clamp the exhibit. At this time, the exhibit can be moved to avoid shaking of the exhibit during the movement. When the exhibit is lifted or lowered for installation, the two first electric telescopic rods 13 are simultaneously extended or shortened to control the sliding block 12 to move synchronously, so as to avoid the two clamping blocks 36 and the exhibit from slipping.

[0034] Further, such as Figure 3 As shown, a rotation groove 121, a slide groove 122 and a mounting groove 123 are provided on one side of the slider 12, a mounting sleeve 31 is rotatably mounted on the inner surface of the rotation groove 121, the threaded rod 32 is threadedly mounted on the inner surface of the mounting sleeve 31, and a first gear 33 is fixedly mounted on the outer surface of the mounting sleeve 31;

[0035] A first motor 35 is fixedly mounted on the inner surface of the mounting groove 123 , and a second gear 34 is fixedly connected to the output shaft of the first motor 35 . The second gear 34 is meshed with the first gear 33 . The slide rod 3 is slidably mounted on the inner surface of the slide groove 122 .

[0036] When the present invention is in use, the output shaft of the first motor 35 drives the second gear 34 to rotate, the second gear 34 further drives the first gear 33 to rotate, the first gear 33 drives the mounting sleeve 31 to rotate, the mounting sleeve 31 can make the threaded rod 32 move along the inner cavity of the mounting sleeve 31 by threaded cooperation with the threaded rod 32, and the sliding rod 3 can slide on the inner surface of the slide groove 122 to make the two clamping blocks 36 approach and be located on both sides of the exhibit to clamp the exhibit.

[0037] Further, such as Figure 4 As shown, a plurality of fifth grooves 361 are opened on one side of the clamping block 36 , and a first spring 362 is fixedly installed on the inner surface of the fifth groove 361 . One end of the first spring 362 is fixedly connected to a limiting column 363 , and the limiting column 363 is slidably installed on the inner surface of the fifth groove 361 .

[0038] When the present invention is in use, since the shapes of the exhibits may be different, in order to avoid the situation where the exhibits cannot be clamped, when the two clamping blocks 36 are close to each other, the first to contact the exhibits are the plurality of limiting columns 363. According to the shape of the exhibits, the outside of the exhibits will squeeze the limiting columns 363, so that the squeezed limiting columns 363 compress the first spring 362 and slide into the inner cavity of the fifth groove 361, while the limiting columns 363 that are not in contact with the exhibits are still in an extended state, which can limit the edges of the exhibits and further avoid the shaking of the exhibits.

[0039] Further, such as Figure 5 and Figure 6 As shown, a second motor 41 is fixedly installed on one side of the support frame 22, and the output shaft of the second motor 41 passes through the support frame 22 and is fixedly connected to one side of the winding column 4. A first connecting plate 43 is fixedly installed on the bottom of the wire 42, and four sixth grooves 431 are opened on the top of the first connecting plate 43, and a connecting rod 432 is slidably installed on the inner surface of the sixth groove 431;

[0040] The outer surfaces of the four connecting rods 432 are all wrapped with a second spring 433, the hooks 44 are fixedly installed at the bottom of the four connecting rods 432, four buffer pads 435 are fixedly installed on the top of the hooks 44, and the tops of the four connecting rods 432 are commonly fixedly connected to a second connecting plate 434, and the wire 42 passes through the second connecting plate 434.

[0041] When the present invention is in use, the output shaft of the second motor 41 drives the winding post 4 to rotate so that the wire 42 can be wound on the outer surface of the winding post 4. When winding, the wire 42 pulls the first connecting plate 43, and the first connecting plate 43 will slide upward along the connecting rod 432. During this process, the second spring 433 will be squeezed and contracted, and then the tension of the wire 42 is transmitted to the hook 44 through the second connecting plate 434 by the four second springs 433, so as to lift the exhibit. By reversing the winding post 4 to make the wire 42 detach from the winding post 4, the exhibit can be lowered and installed. The four second springs 433 can prevent the tension of the wire 42 from directly acting on the hook 44 and the exhibit, thereby preventing damage to the exhibit due to excessive tension.

[0042] Further, such as Figure 2 and Figure 7 As shown, the inner surface of the second groove 21 is provided with two third grooves 211 and two fourth grooves 212, the inner surfaces of the third groove 211 and the fourth groove 212 are slidably mounted with the first slide 5 and the second slide 51, respectively, and the inner cavities of the first slide 5 and the second slide 51 are slidably connected to the limit block 52;

[0043] A limiting hole 521 is provided on the top of the limiting block 52, and the wire 42 is slidably installed on the inner surface of the limiting hole 521. A plurality of limiting slots 53 are provided on the outer surface of the limiting block 52. The first slide 5 and the second slide 51 are both slidably installed on the inner surfaces of the limiting slots 53. A second electric telescopic rod 54 is fixedly installed on one side of the first slide 5 and the second slide 51, and the output ends of the two second electric telescopic rods 54 are fixedly installed on the outer surface of the limiting block 52.

[0044] When the present invention is in use, when the exhibit is moved to the placement point, it is also necessary to fine-tune the position of the exhibit. The two second electric telescopic rods 54 can cooperate with the extension and contraction to allow the limit block 52 to move freely in the inner cavity of the second groove 21, and because the wire 42 passes through the limit block 52 through the limit hole 521, when the limit block 52 moves, the wire 42 will also move with the limit block 52. When the limit block 52 moves, the two second electric telescopic rods 54 start to work respectively, thereby causing the first slide 5 and the second slide 51 to slide on the inner surfaces of the third groove 211 and the fourth groove 212 respectively, and the first slide 5 and the second slide 51 both slide on the inner surface of the limit slot 53, thereby achieving fine-tuning of the installation position of the exhibit.

[0045] Working principle: first hang the hook 44 on the top of the exhibit, and the output shaft of the second motor 41 drives the winding post 4 to rotate so that the winding post 4 can tighten the wire 42 and thus lift the exhibit. In the process of lifting the exhibit, the wire 42 will first pull the first connecting plate 43, and the first connecting plate 43 will slide along the four connecting rods 432 and press the four second springs 433 at the same time. Then the four second springs 433 will transfer the pressure to the second connecting plate 434, and the second connecting plate 434 will lift the hook 44 through the four connecting rods 432 and then lift the exhibit. This can avoid the tension of the wire 42 directly acting on the exhibit and causing damage to the exhibit.

[0046] After the exhibit is lifted, the output shaft of the first motor 35 drives the second gear 34 to rotate, and the second gear 34 meshes with the first gear 33, so that the first gear 33 drives the mounting sleeve 31 to rotate on the inner surface of the rotating groove 121. At this time, since one end of the threaded rod 32 is fixed to one side of the clamping block 36, the sliding rod 3 slides in the inner cavity of the sliding groove 122, and when the mounting sleeve 31 rotates, it can drive the clamping block 36 to approach the exhibit, and then the limiting column 363 contacts the exhibit, and the edge of the exhibit squeezes the limiting column 363, and the limiting column 363 slides into the inner cavity of the fifth groove 361 and moves forward. The first spring 362 is squeezed in one step, while the limiting column 363 which is not squeezed is at the edge of the exhibit to limit the exhibit, so as to prevent the exhibit from shaking during the movement. After the exhibit is moved to the placement point, it may be necessary to fine-tune the position of the exhibit. During the fine-tuning, the two second electric telescopic rods 54 are extended and shortened to drive the first slide 5 and the second slide 51 to slide on the inner surfaces of the third groove 211 and the fourth groove 212 respectively, so as to adjust the position of the limiting block 52. The limiting block 52 moves with the wire 42, so as to fine-tune the position of the exhibit.
