Description

Technical Field

[0001] The utility model relates to the technical field of display module fixing structures, in particular to a direct-insertion locking structure and a display screen. Background Art

[0002] Large-screen displays are now widely used in commercial scenarios such as indoor and outdoor spaces of large shopping malls, commercial streets, etc. due to their advantages such as high brightness, long life, and wide viewing angle.

[0003] At the same time, in order to meet people's increasing demand for visual stimulation, the size of display screens is getting larger and larger. In order to cope with the larger and larger display modules, the fixing mechanism corresponding to the display module usually adopts a locked fixing mode. Although it meets the demand for stability in display module installation, its defects are also obvious: first, it is difficult to disassemble and does not support disassembly and maintenance from the front of the display module; second, since the traditional fixing mechanism adopts a locked mode, when the display module or the chassis where it is located is deformed or the relative position changes due to external force, the traditional fixing mechanism may deform along with the display module or the chassis, causing the fixing mechanism to get stuck, which causes great difficulties for subsequent maintenance and disassembly; in severe cases, the traditional fixing mechanism may directly deform and fail to lock the display module, causing the display module to fall off, posing a safety hazard.

[0011] As a more preferred embodiment, the spring sheet includes a receiving portion and a tightening portion, one end of the receiving portion is fixed on the base, one end of the tightening portion is integrally formed with the other end of the receiving portion and extends toward the inner side of the elastic clamping cavity, a plurality of the receiving portions enclose the receiving space of the elastic clamping cavity, and a plurality of the tightening portions enclose the tightening mouth of the elastic clamping cavity.

[0012] As a more preferred embodiment, the spring sheet also includes a guide portion, which is integrally formed at the other end of the tightening portion and extends toward the outside of the elastic clamping cavity, and a plurality of the guide portions enclose a guide opening of the elastic clamping cavity; when the other end of the fixing column is inserted into the elastic clamping cavity, the convex head portion abuts against the guide portion of the spring sheet and applies a certain pressure to the spring sheet, and the guide portion expands outward under the action of the pressure, thereby driving the tightening opening and stretching the tightening opening, and the convex head portion passes through the tightening opening and is arranged in the accommodating space to complete the connection between the fixing column and the elastic clamping cavity; when the other end of the fixing column is pulled out of the elastic clamping cavity, the convex head portion applies pressure to the tightening portion of the spring sheet, the tightening opening is stretched open, the convex head portion passes through the tightening opening, and the fixing column is pulled out.

3. The in-line locking structure (1) according to claim 2, characterized in that: The clamping claw mechanism (13) further comprises a plurality of spring sheets (132), one end of each of the spring sheets (132) being fixed on the base (131), and the plurality of spring sheets being symmetrically arranged about the center of the base (131), and the elastic clamping cavity (134) being enclosed by the plurality of spring sheets (132).

4. The in-line locking structure (1) according to claim 3, characterized in that: The spring sheet (132) comprises a receiving portion (132a) and a tightening portion (132b), one end of the receiving portion (132a) is fixed on the base (131), one end of the tightening portion (132b) is integrally formed with the other end of the receiving portion (132a) and extends toward the inner side of the elastic clamping cavity (134), a plurality of the receiving portions (132a) enclose a receiving space (134a) of the elastic clamping cavity (134), and a plurality of the tightening portions (132b) enclose a tightening opening (134b) of the elastic clamping cavity (134).

5. The in-line locking structure (1) according to claim 4, characterized in that: The spring sheet (132) further comprises a guide portion (132c), wherein the guide portion (132c) is integrally formed at the other end of the tightening portion (132b) and extends toward the outside of the elastic clamping cavity (134), and a plurality of the guide portions (132c) enclose a guide opening (134c) of the elastic clamping cavity (134).

6. The in-line locking structure (1) according to claim 1, characterized in that: The outer contour of the supporting foot (133) is in the shape of a Chinese character "X", and the protrusion of the supporting foot (133) faces the side of the fixed body (2).
