[0024] The technical scheme of the utility model is further described below, but the scope of protection is not limited to the description.

[0025] A cabinet debugging tray, comprising: a tray 1, two fixed supports 2 are arranged at two ends of one side of the tray 1, and the two fixed supports 2 are hinged to a cabinet door 6; the hinge structure provides a rotating axis, so that the tray can rotate freely around the fixed support point. The fixed support acts as a support point, and transmits torque through a mechanical hinge, so as to ensure that the rotating action is stable and the bearing capacity is reliable.

[0026] The folding stopper 3 is connected with the tray 1 and the control cabinet door 6 respectively, when the tray 1 is in the horizontal unfolded state, the folding stopper 3 is straightened to provide support, when the tray 1 is rotated to the vertical storage state, the folding stopper 3 is folded; the stopper adopts two hinged pull rods, forms a stable triangular support structure (geometric stability principle) when unfolded, effectively disperses the tray load; the hinge point allows the pull rod to overlap when folded, reducing space occupation.

[0027] The tray fixing lock 4 is installed on the cabinet door 6, when the tray 1 is stored, the tray fixing lock 4 locks the tray 1. The fixed lock forms a physical constraint through the mechanical cooperation (clearance fit + three-fold plate structure) of the lock tongue and the stud. The vertical three-fold plate design of the lock tongue enhances the bending strength, the stud and the nut adjust the locking force to ensure reliable locking.

[0028] The fixed support 2 is fixed on the reinforcing rib 5 by bolting or welding, the reinforcing ribs 5 are parallel and vertical to each other and are installed on the cabinet door, and the reinforcing rib 5 is uniformly distributed with a plurality of bolt holes. The reinforcing rib is a local reinforcing structure of the cabinet door, which disperses the tray load by vertical parallel distribution (uniform load principle); the bolt hole design allows the position of the fixed support to be adjusted to adapt to different sizes or installation scenes.

[0029] The folding stopper 3 is two pull rods hinged at one end, the length of which matches the horizontal unfolded state of the tray 1. The length of the pull rod is accurately matched with the geometric size of the tray in the unfolded state (length matching principle), and the hinge point allows the pull rod to freely stretch and retract, forming a rigid straight support when unfolded, avoiding support failure due to insufficient length.

[0030] The tray fixing lock 4 includes a stud 41, one end of the stud 41 is fixed inside the cabinet door 6, and the other end is assembled with the lock tongue 44 on the stud 41 through the cooperation of the nut 46 and the washer. The three-fold plate structure improves the deformation resistance through the bending process (increasing the sectional moment of inertia); the clearance fit (tolerance design) allows the lock tongue to slide slightly along the stud, facilitating assembly and adjusting the locking angle.

[0031] The lock tongue is a vertical three-fold plate, one end of which is processed with a through hole, and the through hole is clearance fit with the stud 41. The anti-slip pattern increases the friction coefficient of the contact surface (tribology principle), and the groove can limit the displacement of the object (mechanical limiting), which ensures the stable placement of the object.

[0032] The surface of the tray 1 is provided with anti-slip patterns or grooves for increasing the stability of the placed objects. Through the thin design (thickness control) and the shape of the inner wall of the cabinet door, the redundant space inside the cabinet door is utilized to avoid interfering with the layout of other equipment.

[0033] The folded state of the tray 1 is in contact with the inner wall of the control cabinet door 6, and the thickness is not more than 10% of the internal space of the cabinet door.

[0034] The tray 1 is made of light metal material or high-strength engineering plastic. Light metal (such as aluminum alloy) has high specific strength; engineering plastic (such as nylon) is corrosion-resistant and insulating, suitable for electrical environment, and surface treatment further optimizes the corrosion / insulation performance.

[0035] As shown in Figure 6 The tray 1 is connected with the reinforcing rib 5 of the control cabinet door 6 through the folding stopper 3, the stopper 3 is unfolded and straightened when the tray 1 is in the horizontal state, and the stopper 3 is in the folded and stored state when the tray 1 rotates around the fixed support 2 to the vertical plane storage state, the tray 1 is buckled by the tray fixing lock 4 installed on the cabinet door 6 in the storage state, preventing the tray 1 from falling down to the horizontal state, and the tray fixing lock 4 installed on the control cabinet door 6 has the function of 360-degree rotation in the vertical plane.
