In order to avoid the slide rail 11 to produce because of receiving external force and slide to bring the difficulty for overhauing, distribution automation terminal control box still includes locking Assembly 6, and locking Assembly 6 sets up on slide rail 11. After the working platform 3 slides to the target position, the pulley 2 and the slide rail 11 are relatively fixed, so that the working platform 3 is prevented from sliding in the box body 1 to influence the overhaul.

In this embodiment, distribution automation terminal control box still includes unblock subassembly 7, and unblock subassembly 7 is used for making locking Assembly 6 unblock pulley 2, makes pulley 2 can move for slide rail 11.

In particular, in the locked state, the locking assembly 6 bears against the outer wall of the pulley 2, thereby locking the pulley 2. In the unlocked state, the locking assembly 6 is away from the pulley 2 so that the pulley 2 can roll freely. The unlocking assembly 7 then restores the work platform 3 from the locked state to the unlocked state by causing the locking assembly 6 to generate a resilient force.

In this embodiment, locking Assembly 6 includes circular arc board 61 and elastic component 62, and the first end of circular arc board 61 and the outer wall butt of pulley 2, its second end are connected with the first end of elastic component 62, and under the effect of elastic component 62, circular arc board 61 can the butt on the outer wall of pulley 2 to locking pulley 2.

Wherein, the top surface of slide rail 11 is provided with the through-hole, and unblock subassembly 7 wears to establish in the through-hole. The unlocking assembly 7 is connected with the second end of the elastic member 62, and the first end of the circular arc plate 61 is far away from the pulley 2 under the action of the elastic member 62 by pressing the unlocking assembly 7.

In this embodiment, in order to facilitate the operation of the service man, the unlocking assembly 7 includes a button 71, an equipment rod 72 and a connecting rod 73, wherein the button 71 is fixedly connected with the equipment rod 72. A rotating rod is arranged in the connecting rod 73, the arc plate 61 is rotatably connected to the rotating rod, and the equipment rod 72 is slidably connected with the connecting rod 73. The elastic member 62 is sleeved on the rotating rod, a first end of the elastic member 62 is connected with the arc plate 61, and a second end of the elastic member 62 is connected with the bottom end of the equipment rod 72.

When needs unblock, press button 71 and drive equipment pole 72, equipment pole 72 passes through elastic component 62 can extrude circular arc board 61, and circular arc board 61 can rotate on setting up the bull stick inside connecting rod 73 to make circular arc board 61 upward movement, thereby liberation circular arc board 61 to the restriction of pulley 2, it can to stimulate that work platform 3 drives pulley 2 and interdynamic.

Illustratively, the elastic member 62 may be a torsion spring.

In order to ensure the sliding stability of the working platform 3, the front end and the rear end of the sliding rail 11 are provided with a locking assembly 6 and an unlocking assembly 7.

Example two

The present embodiment provides a distribution automation terminal control box, which is different from the first embodiment only in the position of the elastic member 62 and the connection relationship thereof with the circular arc plate 61 and the connection rod 73.

Specifically, connecting rod 73 is fixed on slide rail 11, and arc plate 61 sets up on connecting rod 73 with rotating, and the first end of arc plate 61 can block with pulley 2, and equipment pole 72 and connecting rod 73 sliding fit, and the lower extreme of equipment pole 72 is articulated with the second end of arc plate 61. The first end of the elastic member 62 is fixed on the bottom surface of the slide rail 11, and the second end thereof is connected to both the lower end of the equipment rod 72 and the second end of the arc plate 61. Under the action of no external force, the elastic part 62 is in a semi-compression state, so that the elastic part 62 exerts an upward acting force on the second end of the arc plate 61, and the first end of the arc plate 61 presses the pulley 2 downwards, so that the pulley 2 is in a locking state. When needing the unblock, the accessible presses equipment pole 72, makes equipment pole 72 downstream and drive circular arc board 61 and rotate around connecting rod 73, and then makes the first end upward movement of circular arc board 61 in order keeping away from pulley 2, realizes the unblock, makes pulley 2 freely roll, realizes the pull of work platform 3 in box 1.

Illustratively, the elastic member 62 may be a spring.

During the use, operating personnel presses button 71, thereby locking Assembly 6 makes pulley 2 roll far away from pulley 2 to drive work platform 3 and slide, when work platform 3 slides to required position, unclamp button 71, elastic component 62 provides the resilience force, makes the first end of circular arc board 61 to being close to pulley 2 direction motion, and then makes work platform 3 be in the locking state and can't slide. While the working platform 3 can maintain the locked state even if it receives an excessive external force by the resilient force of the elastic member 62.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
