During the production and processing of digital color screens, it is often necessary to carry their finished or semi-finished products to facilitate use at different positions. For this purpose, corresponding conveying equipment is required for auxiliary handling. The commonly used internal factory handling equipment is to carry out handling through a transfer cart. In order to better protect the handling, the existing handling cart will add corresponding limiting structures during use, so as to ensure higher stability during handling. For example, a conveying device for the production and processing of liquid crystal screens disclosed in Chinese Patent Publication No. CN218929530U. However, the use of the limiting structure will limit the use of the handling cart, and it can only be used for special vehicles, resulting in a single function and unable to meet the use requirements.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and detailed implementation manners:

[0020] As Figures 1 to 5 shown, a conveying device for digital color screen production and processing in an embodiment of the present utility model preferably includes a frame body and universal wheels 1 arranged at the four corners below the frame body. The frame body includes a bottom plate 2 and a vertical frame 3 arranged on the bottom plate 2. A carrier 4 is rotatably arranged on the vertical frame 3 above the bottom plate 2, and a plurality of positioning members 5 for positioning and placing color screens are arranged on the carrier 4. Among them, a support rod 6 is rotatably arranged on the lower side of the carrier 4, and a positioning groove 7 capable of fitting with the lower end of the support rod 6 is arranged on the bottom plate 2. When the support rod 6 is located in the positioning groove 7, the carrier 4 is in a horizontal flat state relative to the horizontal plane.

[0021] Specifically, the carrier can be rotated and folded for storage relative to the vertical frame. Furthermore, the positioning members for positioning and placing digital color screens are arranged on the carrier, so that the positioning members can be folded and stored together with the carrier. Thus, when not in use, the carrier plate can be rotated and stored on the vertical frame, and the bottom plate can be used as a carrier for stacking and conveying other items. When it is necessary to transport digital color screens, the carrier plate can be flipped and supported by the support rod to form a horizontal and straight state. Furthermore, the positioning members are used as a limiting structure for transporting digital color screen products, thereby realizing multiple functions and greatly increasing the applicability.

[0022] Furthermore, the positioning member 5 includes a plurality of U-shaped connecting rods 51. The plurality of U-shaped connecting rods 51 are respectively rotatably arranged on the carrier 4 through rotating shafts, and the plurality of U-shaped connecting rods 51 are arranged at intervals along the length direction of the carrier 4. A positioning area 52 for placing color screens is formed between adjacent U-shaped connecting rods 51. Furthermore, digital color screen products can be placed in the positioning area 52 to realize the limited placement of digital color screens, increase the stability during the conveying of digital color screens, and in order to maintain better stability, the structure of limiting flanges can be added to the outer side walls at both ends of the U-shaped connecting rod.

[0023] Among them, gears 53 are coaxially and fixedly arranged on the rotating shafts of a number of U-shaped connecting rods 51 respectively. One side of the carrier 4 is provided with a rack 54 that can reciprocate along the length direction of the carrier 4. The rack 54 meshes with the gears 53. Two positioning pin holes 55 are arranged at intervals along the length direction on one side of the rack 54. Through holes 56 are provided on one side of the carrier 4 corresponding to the positioning pin holes 55. A pin (not marked in the figure) is detachably inserted between any positioning pin hole 55 and the through hole 56.

[0024] Specifically, through the meshing of the rack and a number of gears, the user can manually drive the rack to rotate. Through the transmission of a number of gears, a number of U-shaped connecting rods are caused to rotate synchronously, so as to realize the folding and storage or unfolding of the U-shaped connecting rods relative to the carrier. The positioning area for placing the color screen is formed between the U-shaped connecting rods in the unfolded state. Through the pin inserted into the through hole of the carrier and the positioning pin hole of the rack in a plug-in fit, the fixed connection of the rack relative to the carrier is realized; there are two positioning pin holes of the rack here, which are the first pin hole and the second pin hole respectively. When the pin is inserted into the first pin hole, the U-shaped connecting rod is fixed relative to the carrier in the folded state. When the pin is inserted into the second pin hole, the U-shaped connecting rod is fixed relative to the carrier in the unfolded state, so as to facilitate the fixing during the folding, storage and unfolding of the U-shaped connecting rod.

[0025] Further, movable grooves 41 are symmetrically arranged on both sides of the carrier 4, and fixed shafts 42 are symmetrically arranged on both sides of the vertical frame 3. The fixed shafts 42 are movably arranged in the movable grooves 41. Through the movable limit cooperation between the movable grooves 41 and the fixed shafts 42, the carrier 4 can rotate relative to the vertical frame 3, and at the same time, the carrier 4 can move vertically relative to the vertical frame 3 to be in a vertical state.

[0026] Further, a limiting member 8 is arranged on the bottom plate 2 to drive the support rod 6 to keep cooperating with the positioning groove 7. The limiting member 8 includes a card slot 81 recessed on one side of the support rod 6. A swing arm 82 is rotatably arranged on one side of the bottom plate 2. A limiting rod 83 is arranged on the swing arm 82. The limiting rod 83 can be rotationally fitted with the swing arm 82 and embedded in the card slot 81. A torsion spring is arranged at the rotational connection between the swing arm 82 and the bottom plate 2. Through the torsion spring, the limiting rod 83 is kept in the connected state of being embedded in the card slot 81. Specifically, by the limiting rod rotating with the swing arm and being embedded in the card slot of the support rod, the support rod is kept in the cooperating state with the positioning groove, so as to effectively increase the structural firmness when the carrier is in the horizontal state.

[0027] Further, the carrier 4, the positioning groove 7 and the support rod 6 correspondingly have a number of them. A number of carriers 4 are arranged at intervals vertically along the vertical frame 3, and the rotational connection parts of the number of carriers 4 and the vertical frame 3 are arranged in a staggered manner along the horizontal direction of the vertical frame 3 respectively. Thus, the folding, storage or unfolding use of a number of carriers relative to the vertical frame can be realized.

[0028] Further, soft pads are respectively adhered to both sides of the U-shaped connecting rod 51, thereby effectively avoiding the problem of scraping and abrasion during the positioning and limiting of the color screen product.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present invention.
