Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a safety control box for elevators. Background Art

[0002] The elevator safety control box is a device used to control the operation of the elevator. It is usually placed in the elevator machine room. The control box of the elevator without a machine room is placed in the shaft. The control box is composed of a sheet metal frame structure and bolt assembly. The sheet metal frame has a uniform size and can be easily hung and removed with plastic pins. The front panel is equipped with a rotatable pin hook to form a lockable rotating door so that all components installed in the control box can be accessed from the front, so that the control box can be installed close to the wall.

[0003] The elevator safety control box is generally installed at a relatively low position. There are many operating buttons on the front of the control box. Non-professionals are not familiar with the operation. Accidentally touching one of the buttons may cause the elevator to malfunction, which may easily cause hidden dangers. For this reason, it is necessary to design an elevator safety control box that can prevent outsiders from accidentally touching it. Utility Model Content

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] As attached Figure 1 To Attachment Figure 3 As shown,

[0019] Specific embodiment: A safety control box for an elevator, comprising a box body 1, the box body 1 is rectangular, a rectangular baffle 2 is provided on the front side of the box body 1, both sides of the baffle 2 near the top are hinged with a first connecting rod 3, the first connecting rod 3 is hinged with a second connecting rod 4, the second connecting rod 4 is hinged with a slider 5, the slider 5 is slidably connected to a first slide rail 6, the slider 5 and the first slide rail 6 are arranged at the top of the box body 1, at least two supports 7 are also provided at the top of the box body 1 near the front side, a rotating block 8 is hinged on the support 7, a T-shaped linear slide 9 is provided on the rotating block 8, a T-shaped linear slide 9 is slidably connected with a T-shaped slide rail 10, the T-shaped slide rail 10 is vertically arranged on the side of the baffle 2 near the box body 1, two sliders 5 are fixedly connected to the same moving block 12 through a connecting plate 11, and the moving block 12 is connected to a linear drive mechanism. The linear drive mechanism includes a screw 13 and a drive motor 14, the two ends of the screw 13 are rotatably connected to two rotating seats 15, and the screw 13 is fixedly connected to the movable end of the drive motor 14.

[0020] The support 7 includes a bottom plate 7-1, and two mounting plates 7-2 are symmetrically arranged on the top of the bottom plate 7-1. The rotating block 8 is hinged between the two mounting plates 7-2. A stopper 7-3 is also fixed on the bottom plate 7-1 to limit the rotation angle of the rotating block 8. The maximum rotation angle of the rotating block 8 is 90°. When the baffle 2 is flipped upward by 90°, it is in a horizontal state. At this time, the baffle 2 can slide horizontally relative to the rotating block 8, and the sliding direction is consistent with the sliding block 5.

[0021] The first connecting rod 3 and the second connecting rod 4 are both provided with a protruding limit block, and after the first connecting rod 3 and the second connecting rod 4 rotate relative to each other by a certain angle, the two limit blocks contact each other to limit the rotation angle between the first connecting rod 3 and the second connecting rod 4. Limiting the rotation angle between the first connecting rod 3 and the second connecting rod 4 can prevent the baffle 2 from being pushed back to its original position only when the slider 5 contacts the baffle 2.

[0022] The utility model elevator safety control box adopts a baffle to cover the control buttons in front of the control box to avoid safety hazards caused by being touched by outsiders. When the baffle needs to be opened, the drive motor 14 works to drive the screw 13 to rotate, and the screw 13 drives the moving block 12 to move backward. The moving block 12 pulls the slider 5 through the connecting plate 11, and the slider 5 pulls the baffle 2 through the hinged first connecting rod 3 and the second connecting rod 4. The baffle 2 initially flips 90 degrees with the rotating block 8 until the baffle 2 is in a horizontal state, and then continues to translate backward under the guidance of the T-shaped linear slide 9 and the T-shaped slide rail 10, and is stored in the top of the box body 2.

[0023] Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
