The present utility model provides a maintenance tool for maintaining a display screen, as shown in fig. 1 to 2, the maintenance tool comprising:

screw rod 1, screw rod 1 include body of rod 11 and threaded connection portion 12, and threaded connection portion 12 locates the one end of body of rod 11, and threaded connection portion 12 is used for being connected with the screw hole on the lamp plate 4 of display screen.

The maintenance tool is characterized in that the maintenance tool is of a screw rod in a core structure, a rod body 11 and a threaded connection part 12 with external threads, wherein the threaded connection part 12 is positioned at one end of the rod body 11, and the threaded connection part 12 is used for being matched with a threaded hole to realize connection. The threaded hole may be a part of the lamp panel 4 or may be a mounting structure provided on the lamp panel 4, such as the boss 41. When the maintenance tool is used, the structure with the threaded holes corresponding to the screw 1 is arranged on the lamp panel 4 of the display screen to be matched with the screw 1, so that the screw 1 is fixed on the lamp panel 4, and the rapid installation of the maintenance tool is realized. The screw 1 is perpendicular to the lamp panel 4 when fixed on the lamp panel 4.

In some embodiments, as shown in fig. 2 to 3, the maintenance tool includes a screw sleeve 2, where the screw sleeve 2 encloses a guide channel, and the screw 1 is disposed through the guide channel.

Wherein, the guide channel is a through hole along the axial direction of the screw rod sleeve 2, and one end of the screw rod sleeve 2 close to the threaded connection part 12 is propped against the surface of the lamp panel 4 when in use so as to keep the screw rod 1 vertical to the lamp panel 4. The screw rod sleeve 2 is sleeved outside the screw rod 1, so that the screw rod 1 is conveniently positioned and guided on one hand, and the maintenance tool is more conveniently held on the other hand.

In some embodiments, as shown in fig. 2, the guide channel includes a through section 21 and a first expansion section 22, the first expansion section 22 being in communication with the through section 21, the first expansion section 22 being proximate to the threaded connection 12, the first expansion section 22 having an inner diameter greater than the inner diameter of the through section 21 and greater than the diameter of the threaded connection 12.

Since the end of the screw sleeve 2 near the threaded connection portion 12 needs to be pressed against the surface of the lamp panel 4 when in use, and the structure with the threaded hole is also disposed on the surface of the lamp panel 4, the present embodiment sets the end of the screw sleeve 2 to enclose the structure with the threaded hole therein. Considering that the screw sleeve 2 is to surround the screw hole, the present embodiment divides the screw sleeve 2 into a through section 21 and a first expansion section 22, the first expansion section 22 communicating with the through section 21, wherein the inner diameter of the first expansion section 22 is larger than the inner diameter of the through section 21 and the diameter of the screw connection 12. When the maintenance tool is used, the first expansion section 22 with a larger inner diameter is propped against the outer side of the threaded hole on the lamp panel 4, the guide channel is perpendicular to the lamp panel 4 and guides the threaded connection part 12 to extend into the threaded hole, and the screw 1 is connected with the lamp panel 4 by rotating into the threaded hole.

In some embodiments, as shown in fig. 2, the maintenance tool further includes a first baffle ring 23, the first baffle ring 23 is disposed inside the lower portion of the through section 21, and an inner diameter of the first baffle ring 23 is smaller than a diameter of the threaded connection 12; or the inner diameter of the through section 21 is smaller than the diameter of the threaded connection 12.

The screw sleeve 2 is internally provided with a structure for blocking the threaded connection 12 from completely penetrating the screw sleeve 2, and various embodiments can be adopted. First, a first baffle ring 23 may be disposed on the inner side of the lower portion of the through section 21, so that the inner diameter of the first baffle ring 23 is smaller than the diameter of the threaded connection portion 12, and the first baffle ring 23 can prevent the threaded connection portion 12 of the screw 1 from entering the through section 21 from the first expansion section 22 and passing out of the screw sleeve 2 from above because the threaded connection portion 12 is located at the first expansion section 22 when the maintenance tool is in use; secondly, considering that the inner diameter of the first expansion section 22 is larger than the inner diameter of the penetration section 21, the diameter of the screw connection 12 can be made larger than the inner diameter of the penetration section 21, so that the blocking of the screw connection 12 by the penetration section 21 can be achieved without providing an additional structure. The specific embodiment is not limited to the above two, as long as the blocking of the threaded connection 12 by the through section 21 can be achieved. The structure adopted in this embodiment facilitates the operation of the maintenance tool.
