[0028] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a portable repair box for maintenance and inspection, including a bottom plate 1, a fixed seat 2 fixedly connected to the bottom plate 1, a lifting screw rod 3 rotatably connected to the bottom plate 1, an adjusting knob 4 fixedly connected to one end of the lifting screw rod 3, a threaded block 5 threadedly connected to the lifting screw rod 3, a hinge rod 6 hinged to the threaded block 5, a connecting block 7 hinged to the end of the hinge rod 6 far from the threaded block 5, a placement box 8 fixedly connected to the connecting block 7, a sliding strip 9 fixedly connected to the bottom of the placement box 8, a sliding groove 10 opened on the bottom plate 1, and the sliding strip 9 is slidably connected in the sliding groove 10. A placement groove 11 is opened on the placement box 8, and a drawer 12 is slidably connected to the placement box 8. The operator can place the commonly used tools for maintenance and inspection in the placement groove 11, and store the infrequently used tools or small parts in the drawer 12. When the tool needs to be taken, the operator rotates the adjusting knob 4, and the adjusting knob 4 drives the threaded block 5 to move downward in the fixed seat 2 through the lifting screw rod 3, so that the threaded block 5 drives the four groups of connecting blocks 7 and the placement box 8 to move outward simultaneously through the hinge rod 6. At this time, the sliding strip 9 at the bottom of the placement box 8 slides in the sliding groove 10, so that the four groups of placement boxes 8 are smoothly extended, and the four groups of placement boxes 8 are unfolded together. Through the provided placement groove 11, drawer 12 and four groups of placement boxes 8, the classified storage of repair tools is realized, which facilitates the access of tools.

[0029] In addition, a top plate 13 is fixedly connected to the fixed seat 2, an extension plate 14 is rotatably connected to the top plate 13, a fixed block 15 is fixedly connected to the top of the placement box 8, a roller 16 is rotatably connected to the fixed block 15, and the roller 16 is in contact with the lower surface of the extension plate 14. While the placement box 8 is moving, the roller 16 at the top of the placement box 8 will push the extension plate 14 to unfold outward until it is flush with the top plate 13, expanding the workbench area, facilitating the placement of various tools and parts, and improving the efficiency of the repair operation. A telescopic rod 17 is fixedly connected to the top plate 13, the telescopic end of the telescopic rod 17 is fixedly connected to a handle 18, moving wheels 19 are provided at the bottom of the bottom plate 1, a pressing threaded rod 20 is threadedly connected to the bottom plate 1, one end of the pressing threaded rod 20 is fixedly connected to a pressing knob 21, and the other end of the pressing threaded rod 20 is rotatably connected to a pressing plate 22. The lifting threaded rod 3 rotates in the fixed seat 2, the adjusting knob 4 is located at the top of the top plate 13, the threaded block 5 slides in the fixed seat 2, multiple hinge rods 6 are provided and evenly distributed on the threaded block 5, four connecting blocks 7 and four placement boxes 8 are provided and evenly distributed on the bottom plate 1, a placement groove 11 is located above the drawer 12, multiple drawers 12 are provided and evenly distributed on the placement box 8, four extension plates 14 and four rollers 16 are provided, four moving wheels 19 are provided and evenly distributed at the bottom of the bottom plate 1, and two pressing plates 22 are provided and arranged symmetrically. By pulling the handle 18 and using the moving wheels 19, the repair box can be moved, and the telescopic rod 17 will be stretched upward accordingly, facilitating the operation of the operator and enhancing the portability. By rotating the pressing knob 21, the pressing plate 22 is driven by the pressing threaded rod 20 to closely fit the ground, preventing the box body from tipping over due to accidental contact or external force during the repair process, ensuring the safety of the repair operation, and guaranteeing the smooth progress of the repair work.

[0030] Working principle: When using this portable repair kit for maintenance inspection, the operator can place the commonly used tools for maintenance inspection in the placement groove 11, and store the less frequently used tools or small parts in the drawer 12. The four groups of placement boxes 8 provided can store a variety of maintenance tools, and can be classified for convenient use. By pulling the handle 18 and using the moving wheels 19, the repair kit can be moved, and the telescopic rod 17 will be stretched upward accordingly, facilitating the operator's use and increasing the portability of the repair kit. After moving the repair kit to the repair site, the compression knob 21 can be rotated. The compression knob 21 drives the compression plate 22 to move downward through the compression threaded rod 20, so that the compression plate 22 closely adheres to the ground, thereby fixing the repair kit in place and preventing it from accidentally tipping over during the maintenance inspection process and affecting the work. When tools need to be taken, the operator rotates the adjustment knob 4. The adjustment knob 4 drives the threaded block 5 to move downward in the fixed seat 2 through the lifting threaded rod 3, so that the threaded block 5 drives the four groups of connecting blocks 7 and the placement boxes 8 to move outward simultaneously through the hinge rod 6. At this time, the sliding strips 9 at the bottom of the placement box 8 slide in the sliding grooves 10, enabling the four groups of placement boxes 8 to extend smoothly, and unfolding the four groups of placement boxes 8 together, facilitating the taking of the maintenance inspection tools in the placement boxes 8. While the placement box 8 is moving, the rollers 16 at the top of the placement box 8 contact and push the extension plate 14 to unfold outward, enabling the four groups of extension plates 14 to unfold to a state flush with the top plate 13, expanding the tabletop range. The operator can place tools or parts on the tabletop composed of the top plate 13 and the extension plate 14, which is convenient to use.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
