For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1 to 4 As shown, this embodiment provides a cabinet panel upward translation support connecting rod mechanism, including: a fixed rod 3, a movable rod 4, an upper turning rod 5 and a lower turning rod 6.

[0031] The fixed rod 3 is fixed to the cabinet 1, the movable rod 4 is fixed to the panel 2 of the cabinet 1, the upper turning rod 5 is hinged at one end to the upper end of the fixed rod 3 and at the upper end of the movable rod 4, and the lower turning rod 6 is hinged at one end to the lower end of the fixed rod 3 and at the lower end of the movable rod 4. During the movement of the panel 2 and the movable rod 4, the direction of the panel 2 remains unchanged, indicating translation. When the panel 2 has fully translated upward from the cabinet 1, the upper turning rod 5 abuts against the movable rod 4. In this embodiment, both the upper turning rod 5 and the lower turning rod 6 have a V-shaped structure.

[0032] like Figures 2 to 4 As shown, one end of the upper turning rod 5 is connected to the upper end of the moving rod 4 through the damping hinge 7, and the fixed rod 3 and the lower end of the upper turning rod 5 and the lower end of the lower turning rod 6, and the moving rod 4 and the upper end of the lower turning rod 6 are all connected for limited rotation through the pin 9 and the retaining spring 91. Due to the action of the damping hinge 7, the connecting rod can realize the arbitrary stop function, that is, the panel 2 can be stopped at will, which is convenient for debugging, maintenance, monitoring, control and other operations. It is simple, convenient, flexible and practical.

[0033] A locking assembly 8 is further provided on the movable rod 4 and the upper turning rod 5 . When the panel 2 is translated upward from the cabinet 1 to the maximum, the switchable locking assembly 8 locks and fixes the upper turning rod 5 on the movable rod 4 .

[0034] The locking assembly 8 comprises a lock catch 81, a rotating shaft 82, a torsion spring 83, a limiting post 84, and a locking post 85. The middle portion of the lock catch 81 is rotatably mounted on the movable rod 4 via the rotating shaft 82. The torsion spring 83 is sleeved on the rotating shaft 82, and the limiting post 84 is mounted on the movable rod 4. One end of the torsion spring 83 abuts the limiting post 84, and the other end abuts the upper end of the lock catch 81. This means that the torsion spring 83 exerts a force on the upper end of the lock catch 81 away from the upper turning rod 5. The locking post 85 is fixed to the lower end of the lock catch 81 and extends toward the upper turning rod 5. The upper turning rod 5 is provided with a slot 87 for the locking post 85 to engage. When the panel 2 is fully translated upward from the cabinet 1, the locking post 85 engages the slot 87, securing the upper turning rod 5 relative to the movable rod 4.

[0035] In this embodiment, a boss 86 is provided on the upper turning rod 5, and a slot 87 is provided on the boss 86 for accommodating the locking column 85 to be inserted into; and an introduction slope 88 is provided on the boss 86 for guiding the locking column 85 into the slot 87. At the same time, the locking column 85 abuts against the boss 86 to cooperate with the limit to prevent the panel 2 from falling due to gravity; in order to facilitate operation, anti-slip stripes are provided on the upper end of the lock buckle 81.

[0036] When opening the panel 2, loosen the locking screws between the panel 2 and the cabinet 1 in advance, hold the handles on the panel 2 with both hands, pull the panel 2 backward, and after the panel 2 is separated from the cabinet 1, push the panel 2 upward until the locking column 85 on the lock 81 hits the guide slope 88 of the upper boss 86. The lock 81 is deflected under the squeezing and guidance of the guide slope 88. At this time, continue to push up until the locking column 85 passes the guide slope 88 and is stuck in the slot 87. The lock 81 is reset under the drive of the torsion spring 83, and the opening process is completed.

[0037] When closing the panel 2, first find the lock 81 on the movable rod 4, and at the same time press the stripe on the upper end of the lock 81 toward the middle of the panel 2. At this time, the locking column 85 on the lock 81 exits the slot 87 on the boss 86. At the same time, hold the handles on both sides of the panel 2 and press down a distance. After the locking column 85 has completed exiting the slot 87, release the pressing of the lock 81 with both hands, press the panel 2 downward until the panel 2 contacts the cabinet 1, lock the locking screws that match the panel 2 and the cabinet 1, and complete the closing of the panel 2.

[0038] The supporting linkage mechanism utilizes the principle of parallelogram instability and parallel opposite sides. When the panel 2 is opened, the display interface always remains facing forward, eliminating the problem of the traditional flip hinge causing the display interface viewing angle to change when the panel 2 is opened and closed. This greatly improves the ability of the cabinet 1 to monitor the display and control panel 2 in real time during maintenance and debugging.

[0039] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
