Description
Technical Field
[0001] The utility model relates to the technical field of shelves, in particular to a storage shelf device with uniform temperature. Background Art
[0002] Four Seasons Pomelo is a variety of pomelo, also called Four Seasons Spring Pomelo. It is rich in vitamin C and various minerals. Storage shelves are shelf systems used to place and store goods. They are usually made of metal, wood or plastic and have a certain load-bearing capacity and structural stability. In order to facilitate the management and protection of Four Seasons Pomelo, storage shelves are usually required.
[0003] When storing pomelo on existing storage shelves, it is usually necessary to adjust the position of the placement board according to the size of the pomelo. When adjusting the position of the placement board, the placement board needs to be removed first, and then multiple people are required to lift the placement board to a suitable position and then fix the placement board, which is more troublesome. In addition, such storage shelves are usually placed indoors. Since the room is in a closed state, it is easy for the air circulation speed of each layer of the shelf to be different, resulting in inconsistent temperatures in different areas, which reduces the freshness.
[0004] Therefore, those skilled in the art provide a storage shelf with uniform temperature to solve the problems raised in the above background technology. Utility Model Content
[0005] In view of the defects in the prior art, the utility model provides a storage shelf with uniform temperature to improve the freshness of four-season pomelo.
[0006] A storage shelf with uniform temperature, comprising four brackets, a lower cover plate, an upper cover plate and a plurality of connecting blocks, a lifting mechanism is fixedly arranged between the end surfaces on both sides of the lower cover plate and the upper cover plate, a placing plate is slidably arranged on the upper and lower sides between the four brackets, a first fixing block is fixedly arranged on one of the two end surfaces on the upper sides of the two placing plates, two second fixing blocks are fixedly arranged on one of the two end surfaces on the lower sides of the two placing plates, sliding grooves are provided on both sides of the front and rear end surfaces of the two placing plates, a plurality of clamping blocks are slidably arranged on the inner walls of the sliding grooves, a plurality of reset springs are fixedly arranged between the clamping blocks and the plurality of sliding grooves, a rotating block is hingedly arranged on the inner walls of the plurality of connecting blocks, and a ventilation mechanism is fixedly arranged between two of the rear sides of the four brackets;
[0007] The two lifting mechanisms include two U-shaped plates, two motors and two first screw rods, the upper sides of the outer end surfaces of the two first screw rods are threadedly sleeved with sliders, and the inner walls of the two sliders are slidably provided with two limit blocks;
[0008] The ventilation mechanism includes a plurality of ventilation plates, two ventilation boxes and two cooling fans. The front end surfaces of the two ventilation boxes are both provided with three second screw rods for rotation, and the outer end surfaces of the plurality of second screw rods are all threadedly sleeved with wind shields.
[0009] Preferably, the lower cover plate is fixedly arranged on the lower side between the four brackets, and the upper cover plate is fixedly arranged on the upper side between the four brackets.
[0010] Preferably, the plurality of connecting blocks are fixedly connected to the plurality of clamping blocks respectively, and the four limiting blocks are slidably connected to the two first fixed blocks in pairs respectively.
[0011] Preferably, the two motors are respectively fixedly arranged on the upper inner walls of the two U-shaped plates, and the output ends of the two motors are respectively fixedly connected to the upper end surfaces of the two first screw rods.
[0012] Preferably, the two first screw rods are rotatably disposed between the inner top surfaces and the inner bottom surfaces of the two U-shaped plates, and the outer end surfaces of the two sliders are slidably disposed on the upper inner walls of the two U-shaped plates.
[0013] Preferably, the two ventilation boxes are respectively fixedly arranged between the end surfaces of the plurality of ventilation plates on opposite sides, and the two heat dissipation fans are respectively fixedly arranged on the rear inner walls of the two ventilation boxes.
[0014] Preferably, universal wheels are fixedly provided on the lower end surfaces of the four brackets.
[0015] The beneficial effects of the utility model are embodied in:
[0016] 1. When it is necessary to adjust the position of the upper placement plate, the connecting blocks on both sides of the placement plate are manually pushed. When it is impossible to continue pushing, the rotating block hinged with the connecting block is rotated to clamp it in the groove opened on the surface of the placement plate, and the slider on the surface of the first screw rod is driven by the motor to slide, and the slider drives the placement plate to move through the first fixed block. After moving to the appropriate position, the rotating block is turned back to the original position, and the clamping block is pushed into the inner wall of the bracket by the rebound force of the reset spring, thereby fixing the placement plate. When it is necessary to adjust the position of the lower placement plate, the first screw rod is driven by the motor to move the slider to the lower end of the two second fixed blocks, and the limit block in the inner wall of the slider is moved to the inner wall of the two second fixed blocks. At this time, the same operation is performed as the upper placement plate. By setting two lifting mechanisms, it is more convenient to adjust the positions of the two placement plates without the need for multiple people to operate.
[0017] 2. After adjusting the positions of the two placement plates, rotate the second screw rod that does not overlap with the placement plates. The second screw rod drives the wind shield plate on its surface to move backward, thereby blocking the hole opened at this point in the ventilation box. Ventilate the ventilation box through the cooling fan, and the wind enters the ventilation plate from the ventilation box, and then enters the placement plates that fit with it from the holes opened in the ventilation plate. Finally, the wind blows downward from the upper cover plate and the lower end surfaces of the two placement plates. By setting up the ventilation mechanism, the air on the upper ends of the two placement plates and the lower cover plate flows at a certain speed, ensuring that the temperature of the two placement plates and the lower cover plate surfaces is uniform, avoiding excessively high temperatures in one area and excessively low temperatures in another area, and improving the freshness of the four-season pomelo.

[0029] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0030] A storage shelf with uniform temperature comprises four brackets 1, a lower cover plate 2, an upper cover plate 3 and a plurality of connecting blocks 12, a lifting mechanism 4 is fixedly arranged between the end surfaces on both sides of the lower cover plate 2 and the upper cover plate 3, a placing plate 5 is slidably arranged on the upper and lower sides between the four brackets 1, a first fixing block 8 is fixedly arranged on one of the end surfaces on the upper sides of the two placing plates 5, two second fixing blocks 14 are fixedly arranged on one of the end surfaces on the lower sides of the two placing plates 5, sliding grooves 9 are opened on both sides of the front and rear end surfaces of the two placing plates 5, a plurality of card blocks 11 are slidably arranged on the inner walls of the sliding grooves 9, a plurality of reset springs 10 are fixedly arranged between the card blocks 11 and the plurality of sliding grooves 9, and a plurality of The inner walls of the connecting blocks 12 are hingedly provided with rotating blocks 13, and a ventilation mechanism 6 is fixedly provided between two of the rear sides of the four brackets 1. The two lifting mechanisms 4 include two U-shaped plates 401, two motors 402 and two first screw rods 403. The upper sides of the outer end surfaces of the two first screw rods 403 are threadedly sleeved with sliders 404, and the inner walls of the two sliders 404 are slidably provided with two limit blocks 405. The ventilation mechanism 6 includes multiple ventilation plates 601, two ventilation boxes 602 and two cooling fans 605. Three second screw rods 603 are rotatably provided on the front end surfaces of the two ventilation boxes 602, and wind shield plates 604 are threadedly sleeved on the outer end surfaces of the multiple second screw rods 603.
[0031] When adjusting the position of the upper placement plate 5, the connecting blocks 12 arranged on both sides of the upper placement plate 5 are manually pushed. When the connecting blocks 12 can no longer be pushed, the rotating blocks 13 integrated with the connecting blocks 12 are manually rotated to insert them into the grooves provided on the surface of the placement plate 5. At this time, the motor 402 is turned on, and the motor 402 drives the first screw rod 403 to rotate. The first screw rod 403 drives its surface slider 404 to slide in the inner wall of the U-shaped plate 401. Two grooves are provided on the lower end surface of the first fixed block 8, and rubber is provided on the inner wall of the groove. The two limit blocks 405 inside the slider 404 are inserted into the grooves provided in the first fixed block 8. When the slider 404 is moved, the first fixed block 8 is driven to move together, and the first fixed block 8 drives the placement plate 5 integrated with it to move together. When the placement plate 5 moves to the appropriate position After the positioning, the rotating block 13 is manually rotated back to its original position. At this time, under the action of the reset spring 10, the block 11 is pushed into the inner wall of the bracket 1, thereby fixing the placement plate 5 between the four brackets 1. When adjusting the position of the lower placement plate 5, the motor 402 and the first screw rod 403 drive the slider 404 to move downward, and the slider 404 drives the two limit blocks 405 integrated therewith to leave the inner wall of the first fixed block 8. When the slider 404 moves to the lower end of the second fixed block 14, the two limit blocks 405 inside the slider 404 are manually moved, and the two limit blocks 405 are respectively inserted into the inner walls of the two second fixed blocks 14, and then the same operation as the upper placement plate 5 is performed. By setting two lifting mechanisms 4, it is more convenient to adjust the position of the two placement plates 5 without requiring multiple people to operate.
[0032] When the positions of the two placement plates 5 are adjusted, the second screw rod 603 that does not overlap with the two placement plates 5 is manually rotated. The second screw rod 603 on the uppermost side does not need to be rotated. The second screw rod 603 drives the wind shield plate 604 on its surface to slide backward. The wind shield plate 604 blocks the holes opened in the ventilation box 602 respectively. When the two cooling fans 605 are working, wind enters the ventilation box 602 through the cooling fans 605, and then the wind enters the ventilation plate 601 from the other unblocked holes in the ventilation box 602. At this time, the wind enters the inner wall of the placement plate 5 that is in contact with it from the holes opened in the ventilation plate 601, and finally the wind blows downward from the lower end surfaces of the upper cover plate 3 and the two placement plates 5. By setting the ventilation mechanism 6, the air on the upper ends of the two placement plates 5 and the lower cover plate 2 flows at a certain speed, ensuring that the temperature of the surfaces of the two placement plates 5 and the lower cover plate 2 is uniform, avoiding excessively high temperature in one area and excessively low temperature in another area, and improving the freshness of the four-season pomelo.
[0033] The lower cover plate 2 is fixedly arranged on the lower side between the four brackets 1, and the upper cover plate 3 is fixedly arranged on the upper side between the four brackets 1. The upper cover plate 3 is used to blow air on the surface of the upper placement plate 5, and the upper end of the upper placement plate 5 is blocked to reduce the adhesion of dust on the surface of the placement plate 5. The four-season pomelo is supported by the lower cover plate 2. Multiple connecting blocks 12 are fixedly connected to multiple card blocks 11 respectively. Four limit blocks 405 are slidably connected to the two first fixed blocks 8 in pairs, and are connected to the card blocks 11 through the connecting blocks 12. In the process of pushing the connecting blocks 12, the card blocks 11 are driven to slide in the sliding grooves 9. The two motors 402 are respectively fixedly arranged on the upper inner walls of the two U-shaped plates 401. The output ends of the two motors 402 are respectively fixedly connected to the upper end faces of the two first screw rods 403, and are connected to the first screw rod 403 through the motor 402. When the output end of the motor 402 rotates, the first screw rod 403 is driven to rotate together.
[0034] The two first screw rods 403 are rotatably arranged between the inner top surface and the inner bottom surface of the two U-shaped plates 401, and the outer end surfaces of the two sliders 404 are slidably arranged on the upper inner walls of the two U-shaped plates 401. The sliders 404 are limited by the inner walls of the U-shaped plates 401 to prevent the sliders 404 from rotating on the surface of the first screw rods 403 when the first screw rods 403 drive the sliders 404 to move. The two ventilation boxes 602 are respectively fixedly arranged between the end surfaces of the opposite sides of the multiple ventilation plates 601, and the two cooling fans 605 are respectively fixedly arranged on the inner walls of the rear sides of the two ventilation boxes 602. By turning on the cooling fans 605, the cooling fans 605 pass the wind from the rear side of the ventilation box 602 to the interior of the ventilation box 602. The lower end surfaces of the four brackets 1 are fixedly provided with universal wheels 7. By arranging the universal wheels 7 at the lower ends of the brackets 1, it is more convenient to move the shelves.
[0035] Working principle: When adjusting the position of the upper placement plate 5, manually push the four connecting blocks 12 integrated with the upper placement plate 5 respectively. When the connecting block 12 cannot be pushed, manually rotate the rotating block 13 integrated with the connecting block 12 and insert it into the groove opened on the upper end surface of the placement plate 5. When the four rotating blocks 13 are all inserted into the groove, turn on the two motors 402. When the placement plate 5 moves to the appropriate position, turn off the motor 402, and manually turn the four connecting blocks 12 back to their original positions again. When the side placement plate 5 is in position, turn on the two motors 402. When the slider 404 moves the lower end of the second fixed block 14, manually push the limit blocks 405 inside the two sliders 404 into the inner wall of the second fixed block 14. At this time, perform the same operation as the upper placement plate 5. After adjusting the positions of the two placement plates 5, manually rotate the second screw rod 603 that does not overlap with the placement plate 5. The second screw rod 603 drives the wind shield plate 604 on its surface to block the holes opened in the ventilation box 602. Finally, turn on the two cooling fans 605.
