In the present invention, the terms "upper", "lower", "left", "right", "middle" and "one" are used for clarity of description, but not for limiting the range of the present invention, and the relative relationship changes or adjustments without substantial technical changes should be regarded as the scope of the present invention.

Referring to fig. 1-3, a ganged locking mechanism for a sideboard of an electric trailer includes:

the bottom of the breast board 1 is hinged with the side wall of the trailer;

the connecting mechanism is used for connecting the breast board 1 and the trailer and comprises connecting pipes 2 and moving assemblies 3, the two moving assemblies 3 are fixedly arranged on two sides of the breast board 1, the two connecting pipes 2 are symmetrically and fixedly arranged on the inner side of the trailer, and the moving assemblies 3 are hermetically and slidably arranged in the connecting pipes 2;

and the fixing component 4 is arranged between the connecting pipe 2 and the breast board 1, and is used for fixedly connecting the connecting pipe 2 and the breast board 1.

Use above-mentioned technical scheme's embodiment, when needs carry out the position deflection with breast board 1, not hard up fixed subassembly 4, make breast board 1 and connecting pipe 2 separation, at this moment remove breast board 1, install the sealed removal of removal subassembly 3 in breast board 1 both sides inside connecting pipe 2, through the inside gaseous extrusion connecting pipe 2 of connecting pipe 2, because the reason of connecting pipe 2 internal pressure, removal subassembly 3 has played the pulling force effect to breast board 1, avoid breast board 1 to remove under self action of gravity, the moving speed of breast board 1 has been reduced, the effect of buffering has been played to the removal of breast board 1, the violent collision of breast board 1 with the trailer has been avoided simultaneously, send the sound, the sufficient reaction time of personnel below breast board 1 is given to the breast board 1 that slows down the moving speed, it does not have enough impact force also to have ensured simultaneously, avoid causing the injury to personnel.

According to the preferable technical scheme in the embodiment, an air cavity 5 is formed in the connecting pipe 2, a plurality of rows of air holes 6 are formed in the side wall of one end, close to the breast board 1, of the connecting pipe, the diameters of the air holes 6 are 2mm-3mm, when the breast board 1 is put down, the moving assembly 3 slides in the connecting pipe 2, air in the connecting pipe 2 is discharged through the air holes 6, and due to the fact that the diameters of the air holes 6 are small, an upward force can be provided for the downward moving breast board 1 in the air discharging process, and the moving speed of the breast board 1 is reduced;

the upper end of one side, close to the breast board 1, of the connecting pipe 2 is provided with the mounting opening 7, the sealing air plug 8 is fixedly clamped inside the mounting opening 7, when a large amount of dust or other substances are accumulated inside the connecting pipe 2, the mounting opening 7 is exposed by pulling the sealing air plug 8, the inside of the connecting pipe 2 is cleaned, and the situation that the moving assembly 3 cannot move inside the connecting pipe 2 is avoided;

the movable assembly 3 comprises a piston 31, a movable rod 32 and a rotating rod 33, the piston 31 is arranged inside the air cavity 5 in a sealing and sliding manner, the two rotating rods 33 are symmetrically and rotatably connected to two ends of the breast board 1, one end of the movable rod 32 is fixedly connected with the piston 31, and the other end of the movable rod penetrates through the connecting pipe 2 to be vertically and fixedly connected with the rotating rods 33, because the connecting pipe 2 is fixed in position, when the breast board 1 moves relative to the trailer, one end of the movable rod 32 moves along with the breast board 1, the movable rod 32 drives the piston 31 to slide in the air cavity 5 in a sealing manner, and the gas originally located inside the air cavity 5 is discharged out of the connecting pipe 2, so that the effect of reducing the moving speed of the breast board 1 is achieved;

the moving rod 32 is made of elastic material and can be bent, when the railing panel 1 deflects relative to the trailer, the moving rod 32 bends, meanwhile, in order to ensure that the railing panel 1 restores the original position, the moving rod 32 can enable the piston 31 to move to the other end of the air cavity 5, and the moving rod 32 is elastic and keeps a rod shape;

the side of the moving rod 32 penetrating through the connecting pipe 2 is fixedly connected with a sealing ring 9, the inner wall of the sealing ring 9 is tightly contacted with the moving rod 32 and is made of rubber, in order to avoid that gas in the gas cavity 5 is discharged from the gas cavity 5 in a large amount at the moment that the breast board 1 moves, the sliding port of the moving rod 32 and the connecting pipe 2 needs to be sealed, so that the deceleration effect of the breast board 1 is ensured;

fixed subassembly 4 includes screw block 41 and go-between 42, go-between 42 fixed mounting is in the one end that connecting pipe 2 is close to breast board 1, and the carriage release lever 32 passes go-between 42, the inside screw thread that has seted up of go-between 42, screw block 41 rotates to be connected on bull stick 33, and carriage release lever 32 passes screw block 41, screw block 41 and go-between 42 threaded connection, when the breast board 1 that need not deflect, railing 1 sets up with the bottom of trailer is perpendicular, carry out threaded connection through rotating screw block 41 and go-between 42, thereby fix the position of breast board 1, this kind of connected mode convenient operation simultaneously, play supplementary effect to the fixed of removing subassembly 3.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
