DETAILED DESCRIPTION

[0018] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0019] As Figs. 1-3 shown, a semi-automatic locking structure for a stop board device includes a shell 1, and an electric push rod assembly 2 is arranged in the shell 1, characterized in that the rod head 3 of the electric push rod assembly 2 is connected and drives a pull block 5, the pull block 5 is provided with a roller support shaft 6 above, the roller support shaft 6 is connected and drives a roller support 8 and a stop board shaft 12, the stop board shaft 12 is connected and drives a stop board 13, one end of the roller support 8 is rotatably connected with a roller 10 through a fixed pin 9, in this embodiment, the fixed pin 9 is welded with the roller support 8 as a whole, the roller 10 rolls on the outer contour of the pull block 5, so as to rotate the roller support 8, the roller support shaft 6, the stop board shaft 12 and the stop board 13 around the axis of the roller support shaft 6 under the push of the pull block 5, so as to raise or lower the stop board 13 by rotation to stop or release the vehicle.

[0020] The outer contour of the pull block 5 in contact with the roller 10 is an inclined surface, so as to push the roller 10 to rise and fall.

[0021] The roller support shaft 6 is connected in transmission with the roller support 8 and a torque transmission sleeve 11 through a torque transmission key 7, and the torque transmission sleeve 11 is connected in key transmission with the stop board shaft 12.

[0022] The baffle plate shaft 12 is welded with one side of the baffle plate 13.

[0023] The electric push rod assembly 2 is connected with the pull block 5 through the connecting pin 4.

[0024] The pull block 5 is slidingly installed in the guide groove of the shell 1.

[0025] The both ends of the roller bracket shaft 6 are rotatably penetrated on the two side panels of the shell 1.

[0026] Action process and principle of the present application

[0027] In the present application, when the electric push rod assembly 2 pushes out the rod head 3, the pull block 5 connected with the rod head 3 through the connecting pin 4 also moves forward, so that the roller 10 is located on the inclined surface of the pull block 5, as shown in the figure, the roller 10 drives the roller bracket 8 to rotate, and then drives the roller bracket shaft 6, the transmission torque sleeve 11, the baffle plate shaft 12 and the baffle plate 13 welded on the baffle plate shaft 12 to rise; due to the existence of the inclined surface of the pull block 5, as long as the roller 10 is located on the inclined surface and the plane at the highest position of the pull block 5, the baffle plate assembly can withstand the forced impact of the vehicle within a certain height range without damaging the original driving element; only by adjusting the angle and height of the inclined surface of the pull block 5, the adjustment of the rising height range of the baffle plate 13 can be realized, and the semi-self-locking state can be realized.
