[0006] Preferably, the locking structure further includes a locking knob, which is sleeved on the locking rod and threaded to the mounting hole. When the locking knob is turned to the designated position, it abuts against the operating knob, restricting the locking rod from sliding along its axial direction, thereby ensuring that the limiting rod is always inserted into the slot, restricting the rotation of the locking rod.

[0007] Preferably, the locking rod and the locking block are arranged perpendicular to each other.

[0008] Preferably, the mounting block has an indicator on the side facing the operating knob.

[0009] Preferably, the outer peripheral wall of the locking knob is provided with anti-slip texture.

[0010] Preferably, the outer peripheral wall of the operating knob is provided with a pressing groove.

[0011] Preferably, the locking rod and the operating knob are connected by a thread.

[0012] Compared with the prior art, the locking structure of the display screen cabinet transport trolley of this application is equipped with an installation block. The installation block is installed on the external trolley guardrail. When it is necessary to lock or unlock the display screen cabinet, simply press the operating knob inward to make the limit rod disengage from the slot and enter one end of the slide groove. Then, rotate the operating knob to make the limit rod slide to the other end of the slide groove. Then, release the knob. Under the action of the locking spring, the operating knob pops outward, driving the limit rod into the slot and preventing the locking rod from rotating. This completes the unlocking or locking operation, which is convenient and quick and improves the efficiency of loading or unloading. Attached Figure Description

[0020] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-3 As shown, this embodiment provides a locking structure for a display screen housing transport trolley, including a mounting block 1, a limiting rod 2, a locking rod 3, a locking block 4, an operating knob 5, and a locking spring 6. The mounting block 1 is installed on the guardrail of the outer trolley and has a mounting hole. The locking rod 3 is slidably inserted into the mounting hole. The outer wall of the locking rod 3 has a sliding groove 8 and two slots 9. The sliding groove 8 is arranged along the circumference of the locking rod 3, and the two slots 9 are arranged one-to-one. The locking rod 3 is located at both ends of the sliding groove 8 and the slot 9 is arranged along the axial direction of the locking rod 3; the limiting rod 2 is installed in the mounting hole and the locking rod 3 is inserted into the sliding groove 8 or the slot 9; the locking block 4 is installed at one end of the locking rod 3 and the operating knob 5 is installed at the other end of the locking rod 3; the locking spring 6 is sleeved on the locking rod 3, one end of the locking spring 6 abuts against the limiting rod 2 and the other end of the locking spring 6 abuts against the operating knob 5.

[0022] In some preferred embodiments of this utility model, the locking structure further includes a locking knob 7, which is sleeved on the locking rod 3 and threadedly connected to the mounting hole. When the locking knob 7 is rotated to a designated position, it abuts against the operating knob 5, restricting the locking rod 3 from sliding along its axial direction. This ensures that the limiting rod 2 is always inserted into the slot 9, restricting the rotation of the locking rod 3. Thus, when it is necessary to lock the operating knob 5, rotating the locking knob 7 causes it to abut against the operating knob 5, preventing the operating knob 5 from being pressed inward and thus preventing the locking rod 3 from rotating, avoiding accidental operation.

[0023] In some preferred embodiments of this utility model, the locking rod 3 and the locking block 4 are arranged perpendicularly to each other.

[0026] In some preferred embodiments of this invention, the outer peripheral wall of the operating knob 5 is provided with a pressing groove. This pressing groove facilitates operation.

[0027] In some preferred embodiments of this invention, the locking rod 3 and the operating knob 5 are connected by a thread. This facilitates the assembly and disassembly of the operating knob 5 and the locking rod 3.

[0028] Compared with the prior art, the locking structure of the display screen cabinet transport trolley of this application is equipped with mounting block 1. Mounting block 1 is installed on the external trolley guardrail. When it is necessary to lock or unlock the display screen cabinet, simply press the operating knob 5 inward to make the limiting rod 2 disengage from the slot 9 and enter one end of the slide groove 8. Then, rotate the operating knob 5 to make the limiting rod 2 slide to the other end of the slide groove 8. Then, release the knob. Under the action of the locking spring 6, the operating knob 5 pops outward, driving the limiting rod 2 into the slot 9, preventing the locking rod 3 from rotating. This completes the unlocking or locking operation, which is convenient and quick, and improves the efficiency of loading or unloading.
