[0026] like Figure 1 As shown, a portable maintenance toolbox for downhole equipment includes a maintenance box 1. At least one side of the left or right outer wall of the maintenance box 1 is equipped with a foldable seat for maintenance personnel to rest. The upper parts of the front and rear side walls of the maintenance box 1 are symmetrically provided with mounting slots 11, and a movable table is hinged to the top of each mounting slot 11. Several storage drawers 7 are provided in the lower parts of the front and rear side walls of the maintenance box 1 (the lower parts of the mounting slots 11) for maintenance personnel to store maintenance tools or parts and prevent loss. A storage cavity is provided in the center of the top of the maintenance box 1, and a height-adjustable mounting frame 5 is slidably installed within the storage cavity. Preferably, the front and rear side walls of the mounting frame 5 are provided with several hooks 6 for maintenance personnel to display the installation tools or parts.

[0027] Preferably, to prevent the mounting bracket 5 from falling back into the storage cavity after being raised, the left and right side walls of the maintenance box 1 are symmetrically provided with limiting grooves 13 near the top; and the bottom left and right sides of the mounting bracket 5 are provided with limiting mechanisms, and the mounting bracket 5 is inserted into the limiting grooves 13 through the limiting mechanisms after being raised.

[0028] like Figure 2 As shown, the mounting frame 5 has an I-shaped cross-section, including a horizontally arranged upper top plate and a lower bottom plate, and a vertically arranged connecting plate between the upper top plate and the lower bottom plate. The front and rear inner walls of the storage cavity are each provided with a first sliding groove; the front and rear sides of the lower bottom plate of the mounting frame 5 slide up and down along the first sliding grooves on the front and rear inner walls of the storage cavity, respectively.

[0029] Preferably, the bottom plate is provided with side sliding grooves 51 at the left and right ends of the bottom of the connecting plate. The limiting mechanism is provided in the side sliding grooves 51. The limiting mechanism includes a spring and a limiting slider 52. One end of the spring is fixed to the inner wall of the side sliding groove 51 away from the groove opening, and the other end is fixed to the limiting slider 52, thereby realizing the sliding connection between the limiting slider 52 and the side sliding groove 51.

[0030] It is worth noting that, in order to facilitate the insertion between the limiting slider 52 and the limiting groove 13, the side of the limiting slider 52 near the limiting groove 13 has a wedge-shaped structure.

[0031] like Figure 3 As shown, the seat includes a seat plate 2 and a support leg 3; one side of the seat plate 2 is hinged to the left or right outer wall of the repair box 1; for easy storage, a placement groove is provided at the bottom of the seat plate 2; the support leg 3 is hinged to the inner wall of the placement groove away from the repair box 1 via a pin, so that after use, the support leg 3 can be tucked into the placement groove, and then the seat plate 2 can be flipped up and placed against the outer wall of the repair box 1. Of course, foldable seats can also be provided on both the left and right outer walls of the repair box 1, and the number of seats is not a further limitation of this utility model.

[0032] like Figure 4As shown, the movable tabletop includes a desktop panel 4 adapted to the mounting groove 11 and a U-shaped connector. The bottom edge of the desktop panel 4 has a connecting frame; the U-shaped connector includes two support rods 41 and a limiting plate 42; one end of each support rod 41 is hinged to the inner sidewall of the left and right sides of the connecting frame, and the other end is rotatably connected to both ends of the limiting plate 42. Preferably, the limiting plate 42 has at least two limiting holes 43, and the mounting groove 11 has at least two fixing protrusions 12 matching the inner diameter of the limiting holes 43. When the movable tabletop is not needed, the U-shaped connector can be folded inward into the groove formed by the connecting frame, and then the desktop panel 4 can be folded downward into the mounting groove 11. When it is necessary to unfold the desktop panel 4, lift the desktop panel 4, open the folded U-shaped connector from the groove formed by the connecting frame, align the limiting hole 43 on the limiting plate 12 that is rotatably connected to the support rod 41 with the fixing protrusion 12 in the mounting groove 11, and insert the fixing protrusion 12 into the limiting hole 43 to complete the limiting and fixing of the desktop panel 4's rotation. At this time, the desktop panel 4 is in a horizontal state, forming a desktop.

[0033] To facilitate the removal of the mounting bracket 5 from the storage cavity, the upper top plate of the mounting bracket 5 is provided with a lifting groove, and a pull rod is provided in the lifting groove.

[0034] To facilitate pushing the repair box 1 and to secure it after it has been moved to a fixed position, the repair box 1 is equipped with self-locking casters at the four corners of its bottom.

[0035] When using the toolbox, first push the entire toolbox to the repair point and activate the self-locking function of the casters to secure the box. If it is necessary to display the tools or parts, the repair personnel use the pull rod to lift the mounting bracket 5 from the storage cavity. When the limiting slider 52 is raised to the limiting groove 13, the spring tension will push the limiting slider 52 on one side of the wedge structure out of the side slide groove 51 and partially insert it into the limiting groove 13, thereby completing the fixed limiting of the mounting bracket 5 and preventing the mounting bracket 5 from falling back into the storage cavity. After the mounting bracket 5 is used, simply press the limiting slider 52 back down. Once the mounting bracket 5 is pushed into the side sliding groove 51, it can be lowered and retracted. When tools or parts need to be placed on the desktop, flip the desktop panel 4 upward and open the U-shaped connector folded in the groove formed by the bottom connecting frame of the desktop panel 4. Insert the limiting hole 43 on the limiting plate 42 into the fixing protrusion 12 in the mounting groove 11 to fix it, thereby completing the rotation limiting of the desktop panel 4. At this time, the desktop panel 4 is in a horizontal state and forms a desktop structure with the top plate of the mounting bracket 5. At the same time, maintenance personnel can also open the seat folded on one side of the maintenance box 1 for rest.

[0036] This utility model has a simple structure, is easy to move and occupies a small area. All major components are connected by pull-out, foldable or lifting methods, making it more suitable for working in narrow spaces in mines.
