An elevator control box includes a bottom shell and a panel. An opening is provided on the bottom shell, and the panel selectively blocks the opening. A driving mechanism and a connecting rod mechanism are arranged inside the bottom shell. The connecting rod mechanism is respectively connected to the driving mechanism and the panel to drive the panel to block or open the opening. By setting the driving mechanism and the connecting rod mechanism to control the movement of the panel, the opening on the bottom shell can be blocked or opened, avoiding using high-elasticity elastic pieces to lock the panel. When maintenance is required, only need to start the driving mechanism as required. Driven by the connecting rod mechanism, the panel moves to the position where the opening is opened. When the maintenance is completed, start the driving mechanism, and the driving mechanism drives the connecting rod mechanism to control the panel to move in the opposite direction to the position where the opening is blocked.

Specific embodiments

[0017] The technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As Figures 1-4 shown, it is an operating box convenient for opening and closing, including a box body 1, a panel body 2 is installed on the front of the box body 1, link mechanisms are arranged at both the top and bottom of the box body 1, the link structure includes a first pin shaft 3 arranged inside the box body 1, a slantingly arranged short connecting rod 4 is connected to the first pin shaft 3, the free ends of the two short connecting rods 4 are connected by a vertical long shaft 5, a second pin shaft 6 is arranged at intervals at the bottom of the panel body 2 on the side of the first pin shaft 3, an inclined first long connecting rod 7 is arranged between the second pin shaft 6 and the long shaft 5, a third pin shaft 8 is arranged inside the box body 1 on the side of the second pin shaft 6, a fourth pin shaft 9 is arranged at intervals at the bottom of the panel body 2 on the side of the third pin shaft 8, and a second long connecting rod 10 is arranged between the third pin shaft 8 and the fourth pin shaft 9.

[0019] Specifically, a limit clamping seat 11 is arranged on the outer surface of the panel body 2 on the other side of the long shaft 5, a fixed seat 12 is arranged on the outer surface of the box body 1, a rotating head 13 is rotatably connected to the fixed seat 12, a compression spring 14 is connected to the side of the rotating head 13 facing the limit clamping seat 11, and the other end of the compression spring 14 is connected to a limit clamping strip 15 inserted into the limit clamping seat 11.

[0020] Specifically, an operating handle 16 is arranged on the front of the panel body 2.

[0021] Specifically, the operating handle 16 is arranged on one side of the limit clamping seat 11.

[0022] Specifically, the inner side of the panel body 2 is arranged in a frame shape, grooves 17 for preventing interference are opened on the inner sides of the panel body 2 where the first pin shaft 3 and the third pin shaft 8 are opposite, when the panel body 2 is in the closed state, one end of the short connecting rod 4 and one end of the second long connecting rod 10 are arranged in the corresponding grooves 17.

[0023] When the operator needs to open the control box, first move the limit clamping strip 15 towards the fixed seat 12, so that the compression spring 14 is in a state of being compressed and stressed. Then rotate the limit clamping strip 15 so that it hangs vertically downward. When the free end of the limit clamping strip 15 disengages from the limit clamping seat 11, the operator holds the operating handle 16 and opens the panel body 2.
