Description

Technical Field

[0001] This utility model relates to the field of auxiliary testing equipment technology, and specifically to an auxiliary inspection tool. Background Technology

[0002] Wheel hub inspection involves various measurements and checks on different types of wheel hubs, requiring the use of numerous specialized tools. Therefore, a dedicated tool cart is typically used to store these tools. Existing tool carts are mostly open-structured, with all items exposed without access control. Furthermore, the open structure lacks protective barriers, making tools prone to falling off, resulting in insufficient safety. Due to the variety of inspection tools, including consumable parts, bolts, and specialized tools, existing tool carts lack clear spatial markings and partitions, leading to disorganized placement, difficulty in finding items, and low efficiency, failing to meet the required neatness and tidiness. During work, different types of wheel hubs often need to be replaced and measured, necessitating the simultaneous use of cutting tools and measuring instruments. Ensuring tool breakage and instrument accuracy is crucial. Current technology typically requires separate tool carts and measuring carts, failing to integrate them into a single unit. This not only makes the retrieval and use of tools and measuring instruments inconvenient but also results in a large footprint.

[0003] In addition, after the wheel hub is processed, a flat and stable platform is needed to facilitate the inspection of its appearance. Therefore, the wheel hub needs to be moved to the designated location for inspection and measurement. The existing tool cart can only hold tools, and the direction of the bottom traveling wheels is fixed, making turning difficult. It cannot move the wheel hub to the designated location stably, safely, and in a time-saving and labor-saving manner, resulting in inconvenience in use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-functional inspection tool cart with clear functional partitions, easy tool classification and storage, safe and convenient use, and the ability to assist in the transportation of wheel hubs.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0006] A multi-functional inspection tool cart includes a cart body. The top of the cart body is provided with a wheel hub placement area for placing wheel hubs and a tool rack for placing cutting tools. The wheel hub placement area and the tool rack are located on both sides of the top of the cart body, and an inspection operation area for performing inspection operations on the wheel hubs is provided between the wheel hub placement area and the tool rack. The interior of the cart body is provided with multiple tool placement areas. The tool placement areas are provided with part placement boxes for placing parts, and the top tool placement area is provided with a measuring tool placement box for placing measuring instruments. The top of the cart features a wheel hub storage area, allowing the tool cart to transport wheel hubs to designated locations for easy inspection and measurement. A tool rack neatly stores tools, and the inspection operation area allows for simple spot checks and measurements on the wheel hubs, offering high flexibility. A measuring tool holder organizes measuring tools, while other parts can be stored in a parts holder. This functional zoning allows for orderly tool placement and integrates the original inspection cart and tool cart into one unit. Routine spot checks and measurements can also be performed in the inspection operation area. The tool holder is conveniently located adjacent to the inspection work area for easy tool access. This multi-functional inspection tool cart features clear functional zoning, is safe and convenient to use, and is particularly suitable for inspection work during wheel hub processing, significantly improving inspection efficiency.

[0007] Preferably, in the aforementioned multi-functional inspection tool cart, the measuring tool storage box is equipped with a slider, and the uppermost tool placement area is equipped with a slide rail that cooperates with the slider. The measuring tool storage box is arranged in the tool placement area in a way that allows it to slide outwards. The slider can slide on the slide rail, thereby enabling the measuring tool storage box to slide out from inside the tool cart body, making it convenient for operators to pick up and use measuring tools during measurement work.

[0008] Preferably, in the aforementioned multi-functional inspection tool cart, the measuring tool storage box includes a box body, a base plate, a support plate, and a support groove for supporting and limiting the support plate. The slider is fixedly disposed on the bottom surface of the base plate. One side of the support plate is hinged to the side of the box body in the outward sliding direction. The support groove is disposed on the base plate and can cooperate with the other side of the support plate. The base plate is also provided with a stop for limiting the sliding of the other side of the box body. The box body is located on the base plate, and a flexible liner is provided inside the box body. The flexible liner is provided with a measuring tool storage groove that matches the size and shape of the measuring tool. Placing measuring tools in their corresponding slots allows for proper classification and management. The flexible inner lining provides effective protection. For measurements requiring frequent tool use, the measuring tool box can be pulled out of the vehicle body, lifted, and the support plate rotated to adjust it to the desired position. The support plate is then locked into its corresponding slot, securing it in place. This raises the outer side of the box, preventing it from slipping due to the inner edge of the base plate. The box then faces the inspection area, facilitating easy access for staff.

[0009] Preferably, in the aforementioned multi-functional inspection tool cart, the tool holder includes an upper tool holder plate and a lower tool holder plate, which are arranged parallel to each other and spaced apart. Each tool holder plate has several tool insertion slots for inserting tools, and these slots are positioned correspondingly. A flexible protective layer is provided below the lower tool holder plate. Tools used for inspection can be placed on the tool holder plate through the tool insertion slots. The upper and lower tool holder plates effectively secure the tools, preventing them from swaying and colliding. The flexible protective layer below protects the ends of the tools, preventing damage.

[0010] Preferably, in the aforementioned multi-functional inspection tool cart, the upper tool placement plate has a guide protective cylinder on its tool placement opening. The upper outer periphery of the guide protective cylinder is secured to the tool placement opening, and the lower end of the guide protective cylinder has multiple guide parts. These guide parts are arranged circumferentially around the tool placement opening at intervals, and are inclined from top to bottom, gradually approaching each other. A channel is formed in the middle of the multiple guide parts for the tool to be inserted and pass through. The guide protective cylinder not only provides auxiliary fixation for the upper end of the tool, but its inclined design of multiple guide parts forms a gradually narrowing channel. When the tool is inserted through this channel, its guiding effect prevents the tool from colliding with the lower tool placement plate due to misalignment. At the same time, the gradually narrowing channel provides better fixation for the tool, preventing the tool from swaying left and right when the tool cart moves. The guide protective cylinder is made of elastic material, which also facilitates the loading and unloading of tools during operation.

[0011] Preferably, in the aforementioned multi-functional inspection cart, the wheel hub placement area is provided with at least one pair of arc-shaped support plates. The pair of arc-shaped support plates are arranged opposite each other, and the bottom of at least one of the arc-shaped support plates is provided with a spacing adjustment component for adjusting the distance between the pair of arc-shaped support plates. The spacing adjustment component includes a spacing adjustment block and a spacing adjustment slide rail. The spacing adjustment slide rail is arranged perpendicular to the arrangement direction of the pair of arc-shaped support plates, and the spacing adjustment block is slidably mounted on the spacing adjustment slide rail. The pair of oppositely arranged arc-shaped support plates can support the arc-shaped edges on the left and right sides of the wheel hub, thereby restricting the movement of the wheel hub and effectively preventing the risk of the wheel hub being bumped or falling off due to shaking when moving the cart. The spacing adjustment component can adjust the distance between the pair of arc-shaped support plates to accommodate wheel hubs of different sizes.

[0012] Preferably, in the aforementioned multi-functional inspection cart, the arc-shaped support plate has a lateral guard extending towards the opposite arc-shaped support plate on its arc-shaped side. The lateral guard further prevents the wheel hub from slipping off the side of the arc-shaped support plate, providing better support and ensuring safe and stable movement during transport.

[0013] Preferably, in the aforementioned multi-functional inspection tool cart, the parts placement box includes multiple upper slot partitions and multiple lower slot partitions. The bottom of the upper slot partitions is fixed to the tool placement area, and the top of the upper slot partitions is provided with multiple upper slots at intervals. The bottom of the lower slot partitions is provided with multiple lower slots at intervals. The lower slot partitions are fixedly mounted on the upper slot partitions through the insertion and engagement of the upper and lower slots. Adjacent upper slot partitions and lower slot partitions form receiving cavities for placing parts. Multiple receiving cavities can be created by the insertion and engagement of multiple upper and lower slot partitions to place different types of parts. In specific use, the number and insertion positions of the upper and lower slot partitions can be adjusted according to needs, thereby flexibly changing the number and size of the receiving cavities.

[0014] Preferably, the aforementioned multi-functional inspection cart has a closed structure, with a safety door on one side that can be opened or closed. This safety door is equipped with a safety lock to restrict its opening. The closed structure creates a sealed storage space inside the cart, effectively preventing items from falling due to bumps and improving safety. Items within the storage space can be easily accessed by opening or closing the safety door. The safety lock establishes access permissions, allowing only authorized personnel to open the safety door and use the items within the storage space, facilitating management.

[0015] Preferably, the bottom of the aforementioned multi-functional inspection cart is equipped with multiple casters, each with a locking mechanism to lock it and restrict its movement. The casters make steering easier and more convenient, while the locking mechanism effectively restricts the casters' rotation, maintaining the cart's stability when it needs to be stationary.
