Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically to an EVA antistatic shelving unit. Background Technology

[0002] EVA antistatic agents refer to the addition of antistatic agents or modification techniques to ethylene-vinyl acetate copolymer (EVA) materials, enabling them to dissipate charges and prevent static electricity buildup. This material combines the inherent flexibility, cushioning, and sealing properties of EVA, while effectively preventing damage to electronic components and precision instruments from electrostatic discharge, or reducing the risk in flammable and explosive environments. It is widely used in electronic product packaging, cleanroom equipment, antistatic flooring, shoe materials, and industrial fields to ensure safe production and use.

[0003] Most shelving units typically have EVA boards on their support plates. Items can be placed directly on the EVA boards to prevent static electricity. However, the spacing between multiple support plates is fixed, making it inconvenient to adjust the position of the support plates or change the spacing. This can lead to wasted space or even the inability to store items due to the height space they occupy.

[0004] Therefore, an EVA anti-static storage rack is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an EVA antistatic storage rack in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: The EVA antistatic storage rack includes a base plate with four casters at the bottom and two adjustable frames at the top. Several support plates are movably mounted on the two adjustable frames, and EVA plates are mounted on the surfaces of the support plates. The base plate has four sets of adjustment mechanisms for auxiliary support, and one of the adjustable frames has a fixing mechanism for constraining the movement of the support plates, with the fixing mechanism in contact with the support plates.

[0007] Furthermore, the adjustment mechanism includes a fixed cylinder, which is fixedly installed on the top of the base plate. A stud is rotatably installed inside the fixed cylinder. A movable column is threaded on the outer wall of the stud and is slidably installed between the fixed cylinder and the base plate. A pad is fixedly installed at the bottom of the movable column, and a knob is fixedly installed at one end of the stud.

[0008] Furthermore, an anti-slip pad is fixedly installed on the bottom of the pad, and the anti-slip pad is made of rubber.

[0009] Furthermore, the fixing mechanism includes a U-shaped plate, which is fixedly installed on the surface of one of the adjusting frames. A fixing frame is fixedly installed on the surface of the U-shaped plate. A stud is rotatably installed on the U-shaped plate. A push post is threaded on the outer wall of the stud and slides on the inner wall of the fixing frame. A knob is fixedly installed at one end of the stud.

[0010] Furthermore, a movable plate is fixedly installed on the surface of the push column, and the movable plate is slidably installed on the U-shaped plate.

[0011] Furthermore, multiple baffles are fixedly installed on the surface of the movable plate, and the baffles are slidably installed on the adjustment frame and in contact with the support plate.

[0012] The beneficial effects of this utility model are as follows: This utility model, through the setting of adjustment mechanism and fixing mechanism, allows for easy use. First, the moving wheels are used to push the shelf to the designated position, and its self-locking function is activated to prevent slippage. If the ground is uneven and the moving wheels are suspended in the air, the adjustment mechanism can be used to contact the ground to form auxiliary support and enhance overall stability. Then, according to the height of the items to be stored, the support plate on the adjustment rack is moved to the appropriate position and locked by the fixing mechanism. Finally, the items are placed on the anti-static EVA board. This allows for flexible adjustment of the storage space height, avoids space waste, provides auxiliary support, improves the stability of item storage, and is simple to operate and highly practical.

Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1-2 As shown, the EVA antistatic storage rack includes a base plate 1, four casters 2 at the bottom of the base plate 1, two adjustable frames 3 at the top of the base plate 1, several support plates 4 movably mounted on the two adjustable frames 3, EVA plates 5 mounted on the surfaces of the support plates 4, and four sets of adjustment mechanisms 6 for auxiliary support on the base plate 1; Figure 1-2As shown, specifically, the adjustment mechanism 6 includes a fixed cylinder 601, which is fixedly installed on the top of the base plate 1. A stud 602 is rotatably installed inside the fixed cylinder 601. A movable column 603 is threadedly installed on the outer wall of the stud 602, and the movable column 603 is slidably installed on the fixed cylinder 601 and the base plate 1. A pad 604 is fixedly installed at the bottom of the movable column 603. A knob 605 is fixedly installed at one end of the stud 602. An anti-slip pad made of rubber is fixedly installed at the bottom of the pad 604.

[0021] More specifically, when the corresponding movable wheel 2 becomes suspended due to ground issues, turning knob 605 causes stud 602 to rotate, moving movable column 603 downwards. The pad 604 and anti-slip pad move accordingly, contacting the ground to fill the suspended position and provide auxiliary support. The anti-slip pad also increases friction with the ground, preventing slippage.

[0022] One of the adjusting frames 3 is equipped with a fixing mechanism 7 for constraining the movement of the support plate 4, and the fixing mechanism 7 is in contact with the support plate 4; for example Figure 1-3 As shown, specifically, the fixing mechanism 7 includes a U-shaped plate 701, which is fixedly installed on the surface of one of the adjusting frames 3. A fixing frame 702 is fixedly installed on the surface of the U-shaped plate 701. A stud 703 is rotatably installed on the U-shaped plate 701. A push post 704 is threaded on the outer wall of the stud 703 and slides on the inner wall of the fixing frame 702. A knob 707 is fixedly installed at one end of the stud 703. A movable plate 705 is fixedly installed on the surface of the push post 704 and slides on the U-shaped plate 701. Multiple baffles 706 are fixedly installed on the surface of the movable plate 705 and slide on the adjusting frame 3, contacting the support plate 4.

[0023] More specifically, by rotating knob 707 clockwise, stud 703 is rotated, causing push post 704 to move laterally, which in turn moves moving plate 705. Multiple baffles 706 move accordingly, moving to the upper surface of support plate 4 to block and constrain it, thus achieving a fixing effect. Conversely, by rotating knob 707 counterclockwise, multiple baffles 706 are disengaged from support plate 4, thus releasing the fixation of support plate 4 and allowing for readjustment. This facilitates the fixing of the position of support plate 4.

[0024] In summary, when using the shelf, first use the casters 2 to push it to the designated position and activate its self-locking function to prevent slippage. If the ground is uneven and the casters 2 are suspended in the air, the adjustment mechanism 6 can be used to make contact with the ground to form auxiliary support and enhance overall stability. Then, according to the height of the items to be stored, move the support plate 4 on the adjustment rack 3 to the appropriate position and lock it with the fixing mechanism 7. Finally, place the items on the anti-static EVA board 5. This allows for flexible adjustment of the storage space height, avoids wasting space, provides auxiliary support, and improves the stability of the stored items. It is simple to operate and highly practical.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
