Description

Technical Field

[0001] This utility model relates to the technical field of conductive material transport devices, and in particular to an antistatic transport device suitable for conductive materials. Background Technology

[0002] In modern electronics, semiconductor, and precision instrument manufacturing industries, the transportation and storage of conductive materials (such as electronic components, metal parts, or specialty chemicals) require extremely high standards. These materials are highly susceptible to accumulating static charge during transport due to friction, induction, and other effects. Once electrostatic discharge (ESD) occurs, it can cause irreversible damage to the materials, or even trigger safety accidents such as fires or explosions. Therefore, ensuring the electrostatic safety of conductive materials during transportation is a significant technical challenge.

[0003] Current conductive material transport devices mostly employ enclosures with conductive or antistatic properties to dissipate static electricity. However, relying solely on the antistatic capabilities of the enclosure material itself is often insufficient. Especially when the enclosure moves on the ground or comes into contact with external objects, static electricity can still accumulate on the enclosure surface. Furthermore, friction between the conductive material and the inner wall of the enclosure during transport can also generate static charge. If there is no additional insulation inside the enclosure, this static charge can directly affect the quality of the materials inside. Moreover, existing transport devices often only focus on static dissipation, neglecting the safety hazard of accidental opening of the transport enclosure lid due to uneven surfaces or improper handling during actual handling. This could lead to materials falling out or secondary contamination, resulting in direct economic losses. Therefore, an integrated transport device that can ensure static safety while simultaneously improving the reliability of the physical locking of the transport enclosure is urgently needed in the industry.

[0004] Therefore, this utility model proposes an antistatic transport device suitable for conductive materials to overcome the shortcomings of the prior art. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an antistatic transport device suitable for conductive materials, comprising: a base plate, casters, a transport box, and a push rod. The casters are disposed at the bottom of the base plate, the transport box is fixedly connected to the top of the base plate, the push rod is fixedly connected to the outer side wall of the transport box, and a handle is fixedly connected to the top of the lid of the transport box. The device also includes a locking component and an insulating component.

[0007] The locking assembly includes a fixed plate, a wrench, a limiting post, a spring, a rotating shaft, a drive shaft, and a fixing block. The locking assembly is fixed to the outer wall of the transport box by the fixing block. The rotating shaft is rotatably connected to the fixed plate. The wrench is fixedly connected to the rotating shaft. The drive shaft is connected to the wrench and drives the limiting post. The spring is connected between the fixed plate and the wrench.

[0008] Preferably, the insulating assembly includes a sliding plate, a pull rod, an insulating plate, a ground wire, and a wire clamp. The insulating assembly is slidably installed inside the transport box. The sliding plate is fixedly connected to one side of the insulating plate. The pull rod is fixedly connected to the sliding plate. One end of the ground wire is electrically connected to the transport box. The wire clamp is fixed to the outer wall of the transport box.

[0009] Preferably, the limiting post is extendably mounted on the fixing plate and is used to cooperate with the lid of the transport box to lock the lid.

[0010] Preferably, the rotation of the wrench is converted into linear motion of the limiting post via the drive shaft.

[0011] Preferably, the spring is used to provide the limiting post with the power to automatically reset when the wrench is released.

[0012] Preferably, the sliding plate slides along a slide rail provided on the inner wall of the transport box.

[0013] Preferably, one end of the pull rod is fixedly connected to the sliding plate, and the other end extends to the outside of the transport box.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 This utility model provides an antistatic transport device suitable for conductive materials, aiming to solve the safety hazards of existing devices for transporting conductive materials, which usually lack effective antistatic structures and whose boxes are prone to accidental opening due to bumps during transportation.

[0027] Specifically, it includes a base plate 1 and a transport box 6 fixedly connected to the base plate 1. Casters 2 are located at the bottom of the base plate 1 to enable flexible movement of the entire device. A push rod 3 is fixedly connected to the outer side wall of the transport box 6 to facilitate the operator to push the device. A handle 5 is fixedly connected to the top of the lid of the transport box 6 to facilitate opening the lid of the transport box 6. It also includes a locking component 4 and an insulating component 7.

[0028] The locking assembly 4 includes a fixed plate 402, a wrench 401, a limiting post 403, a spring 404, a rotating shaft 405, a drive shaft 406, and a fixing block 407. The locking assembly 4 is fixed to the outer wall of the transport box 6 by the fixing block 407. Inside the locking assembly 4, the rotating shaft 405 is rotatably connected to the fixed plate 402, the wrench 401 is fixedly connected to the rotating shaft 405, the drive shaft 406 is connected to the wrench 401 and drives the limiting post 403, and the spring 404 is connected between the fixed plate 402 and the wrench 401 to provide a reset force.

[0029] The insulation component 7 includes a sliding plate 701, a pull rod 702, an insulation plate 703, a ground wire 704, and a wire clamp 705. The insulation component 7 is slidably installed inside the transport box 6 to isolate the conductive materials inside the box. Inside the insulation component 7, the sliding plate 701 is fixedly connected to one side of the insulation plate 703 to drive the insulation plate 703 to slide. The pull rod 702 is fixedly connected to the sliding plate 701 to facilitate the operator to pull it out from the outside. One end of the ground wire 704 is electrically connected to the transport box 6 to conduct away the static charge on the box. The wire clamp 705 is fixed to the outer wall of the transport box 6 to store and fix the ground wire 704 when not in use.

[0030] To reliably lock the lid, a limiting post 403 is extendably mounted on a fixing plate 402. The fixing plate 402 has a through hole for the limiting post 403 to pass through and guide. The end of the limiting post 403 is designed to be, for example, wedge-shaped or cylindrical. When extended, the limiting post 403 is used to cooperate with the lid of the transport box 6 to lock the lid. Specifically, the side edge of the lid of the transport box 6 is provided with a corresponding locking hole or groove. When the limiting post 403 is extended, the end of the limiting post 403 is inserted into the locking hole or groove, thereby restricting the opening movement of the lid and achieving a secure lock.

[0031] To achieve the transmission of the operation of the wrench 401 to the action of the limiting post 403, the rotation of the wrench 401 is converted into the linear motion of the limiting post 403 through the drive shaft 406. The drive shaft 406 can adopt a linkage structure, a gear and rack structure or a cam structure. The drive shaft 406 is preferably a linkage that is eccentrically connected to the wrench 401. The other end of the linkage is hinged to the tail of the limiting post 403. When the wrench 401 rotates around the rotation shaft 405, the linkage pushes or pulls the limiting post 403, so that the limiting post 403 performs linear reciprocating motion in the guide hole of the fixed plate 402, that is, linear motion, thereby realizing the extension locking or retraction unlocking.

[0032] To ensure the automatic reset of the locking mechanism, spring 404 provides the power for the automatic reset of the limit post 403 when the wrench 401 is released. Spring 404 is preferably a torsion spring, which is mounted on the rotating shaft 405. One end of the torsion spring is fixed to the fixed plate 402, and the other end acts on the wrench 401. When the operator moves the wrench 401 to retract (unlock) the limit post 403, the torsion spring is compressed or twisted to store elastic potential energy. When the operator releases the wrench 401, spring 404 releases the elastic potential energy, drives the wrench 401 to rotate in the opposite direction, and drives the limit post 403 to automatically extend to the locked position through the drive shaft 406, thereby realizing automatic reset and locking, which improves the convenience and safety of operation.

[0033] To improve the smoothness of the movement of the insulating assembly 7, the sliding plate 701 slides along the slide rails provided on the inner wall of the transport box 6. Two or more slide rails are symmetrically fixed on the opposite inner walls of the transport box 6. The cross-sectional shape of the slide rails is, for example, C-shaped or L-shaped. Sliding blocks or grooves that cooperate with the slide rails are provided on the two sides of the sliding plate 701. The sliding plate 701 is engaged in the slide rails by the sliding blocks or grooves. This sliding engagement structure not only provides a clear guide for the movement of the insulating plate 703, but also ensures the stability of the insulating plate 703 during the pulling process, preventing jamming or swaying.

[0034] For ease of operation, one end of the pull rod 702 is fixedly connected to the sliding plate 701, and the other end extends to the outside of the transport box 6. The pull rod 702 passes through a through hole opened in the wall of the transport box 6. A sealing element can be provided around the through hole to maintain the airtightness of the box. A T-shaped handle or pull ring can be fixedly connected to the end of the pull rod 702 outside the transport box 6, so that the operator can grip and exert force. By pulling outward or pushing inward, the sliding plate 701 and the fixedly connected insulating plate 703 can be driven to slide on the slide rail, so as to adjust the position of the insulating plate 703 inside the box.

[0035] To achieve effective static electricity conduction, one end of the ground wire 704 is electrically connected to the metal casing of the transport box 6. Since the transport box 6 itself is made of conductive materials (such as stainless steel or aluminum alloy), the ground wire 704 forms a reliable low-impedance electrical connection with the metal casing of the transport box 6 by means of bolts, welding or conductive adhesive. The other end of the ground wire 704 is usually equipped with alligator clips or grounding plugs for connecting to the grounding system of the building or workbench, thereby safely conducting the static charge that may accumulate on the transport box 6 to the ground and preventing electrostatic discharge from damaging the conductive materials inside the box.

[0036] Working Principle: In using this anti-static transport device suitable for conductive materials, the base plate 1 provides a stable foundation for the entire device. A transport box 6 is fixedly connected above it, forming a closed space for holding the conductive materials. A push rod 3 is fixed to one edge of the base plate 1, and a handle 5 is fixed to the top of the transport box 6. Casters 2 are connected to the four corners of the bottom of the base plate 1 via axles, allowing for flexible movement of the device. An insulating component 7 is slidably connected to the inside of the transport box 6. A locking component 4 is fixed to the side of the transport box 6 near the push rod 3 and above the casters 2 via a fixing block 407. The entire device, through the coordinated operation of all components, forms a complete anti-static transport structure, enabling convenient and safe transport of conductive materials. When the device needs to be moved, adjusted, or fixed, the operator pushes the push rod 3, which rotates the casters 2 at the bottom of the base plate 1, allowing the device to move in any direction.

[0037] When the lid needs to be secured, the wrench 401 in the locking assembly 4 rotates around the rotating shaft 405, thereby driving the drive shaft 406 to move. The drive shaft 406 pushes the limiting post 403 to move back and forth, so that the limiting post 403 is fixed to the transport box 6. At the same time, the fixing plate 402 provides stable installation support for the various components of the locking assembly 4. The spring 404 is fixed between the fixing plate 402 and the wrench 401. When the wrench 401 is released, the limiting post 403 automatically resets and limits its position, ensuring the accuracy of the locking action. During the transportation of conductive materials, the insulating assembly 7 plays an anti-static role. The insulating plate 703 slides on the sliding plate 701. Inside the transport box 6, conductive materials are isolated and insulated to prevent static electricity generation. A sliding plate 701 is located on one side of the insulating plate 703 to facilitate the loading and unloading of conductive materials. One end of the pull rod 702 is fixedly connected to the sliding plate 701. Operators can pull the pull rod 702 to move the sliding plate 701, enabling convenient loading and unloading of conductive materials. One end of the ground wire 704 is electrically connected to the transport box 6, and the other end is grounded. When not in use, it is secured by the wire clamp 705 to conduct any small amount of static electricity that may be generated on the device to the ground in a timely manner, further improving the anti-static effect. All components work together to ensure that conductive materials are protected from static damage during transportation, while also ensuring the flexibility and stability of the device's movement and fixation.
