Abstract

The utility model relates to a bidirectional adjustable screw, which comprises a screw head and a screw rod which are connected integrally; the end surface of the screw head is provided with a head pulling groove, and the end surface of the tail part of the screw rod is provided with a tail pulling groove; the tail pulling groove can be a strip-shaped groove, a cross groove, a hexagonal groove or a square groove and the like. The utility model is arranged on the box body corresponding to the four corners of the display module, and the end surface of the screw head faces the back of the display module; after the display screen is built and installed, the flatness of the product can be adjusted under the condition that the product is not detached, the risk in the dismounting process is greatly avoided, the after-sale maintenance treatment is optimized, and the adjustment efficiency in the product flatness adjustment process is greatly improved.

Description

Bidirectional adjustable screw

Technical Field

The utility model belongs to the technical field of the connecting piece, a two-way adjustable screw is related to.

Background

In recent years, with the continuous improvement of the demand of people on display equipment and the rapid development of LED full-color display screens, the requirement of rapid and efficient adjustment of the surface flatness of the LED display screens is particularly important. At present, two situations exist in a screen body building site, wherein a reserved operation space is arranged on the rear side of a first building screen body, and no reserved operation space is arranged on the rear side of a second building screen body; to first kind build that there is the headspace screen body rear side, in the roughness adjustment process between the display module, current regulation mode regulation efficiency is relatively poor.

After the LED display screen is built and installed, the section difference around easily appearing between each display module assembly guarantees the relative roughness on display screen body surface for eliminating the section difference between each display module assembly, and present conventional regulation mode is: and screws are arranged on the box body, the surface of the head of the screw faces the back of the display module, and the front and back positions of the display module are adjusted through adjusting screws so as to eliminate the step difference. However, after the display module is mounted after the screws are adjusted, the screw heads are clamped between the box body and the display module, and if a front section difference and a rear section difference exist between the display module, the display module needs to be detached, and the screws need to be adjusted. Therefore, the flatness of the screen body needs to be guaranteed, the display box body needs to be repeatedly disassembled, time and labor are wasted, in the disassembling and assembling process of the display box body, the phenomena of angle loss and edge loss are easy to occur, and the working efficiency is lower.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a two-way adjustable screw, this screw can effectively be solved and relapse the problem of dismantling the display module assembly, improves work efficiency.

In order to solve the technical problem, the bidirectional adjustable screw of the utility model comprises a screw head and a screw rod which are connected integrally; the end face of the screw head is provided with a head plate groove, and the screw is characterized in that the end face of the tail part of the screw is provided with a tail plate groove.

The tail part wrenching groove is a strip-shaped groove.

The tail pulling groove is a cross groove.

The tail part plate groove is a hexagonal groove.

The tail part plate groove is a square groove.

For the first built screen body with reserved space at the rear side, the utility model is arranged on the box body corresponding to the four corners of the display module, and the end surface of the screw head faces the back of the display module; after the display module is installed, if the front-back section difference exists between the display modules, the end part of a screwdriver or the head part of a wrench can be inserted into the tail part wrenching groove, the screwdriver or the wrench is rotated to enable the bidirectional adjustable screw to rotate, and then the front-back position of the display module is adjusted to eliminate the front-back section difference between the display modules.

The utility model discloses increased the function that LED display screen structure rear side was adjusted, build the installation back at the display screen, if the product front surface roughness is relatively poor, under the condition of not dismantling the product, also can adjust the product roughness, very big risk of having avoided the dismouting in-process, the after-sale processing of maintenance has also been optimized simultaneously, pull under the condition of groove wearing and tearing appearing the head, can follow another direction and screw out the replacement, adjust the simple operation, very big improvement the regulation efficiency in the product roughness adjustment process.
