When the protective cover 2 rotates to the preset position, that is, the protective cover 2 is horizontally located above the top end of the box body 1, the bottom end of the first transmission piece 31 is connected with the limiting bolt, so that the first transmission piece 31 is limited to continue rotating, and the protective cover 2 is accurately located at the preset position.
In summary, by adopting the above structure, the protecting cover 2 can be opened and closed under the cooperation of the driving mechanism 4 and the transmission mechanism 3. Simultaneously, play the effect of direction through setting up guide 33 and slide 34 to the rotation of protective cover 2 for protective cover 2 can be more accurate rotate to corresponding position, and this structure can carry on spacingly to protective cover 2 closed position, thereby makes protective cover 2 can be accurate and stable be in the closed condition. Further, the side plate 12 of the box body 1 is further provided with a limiting member 7, and the first transmission member 31 is limited to continue rotating by setting the limiting member 7, so that the opening position of the protecting cover 2 is limited, and the protecting cover 2 is accurately located at the preset opening position. Therefore, under the action of the structure, the protective cover 2 can be accurately and stably opened and closed, so that the coupler 8 can be extended and retracted without obstacles; meanwhile, the box body 1 is completely covered outside the coupler 8, and the coupler 8 can be effectively protected. Moreover, the device has simple structure and convenient installation; compared with a protection structure in the prior art, the protection range is large, and the main coupling parts such as a coupler 8 coupling system and an electric connector can be covered, so that the protection effect is greatly improved. Therefore, the technical problem that the effect is poor due to the small protection range of the coupler protective device in the prior art is solved.
For a clearer explanation of the present application, the working principle of the present invention will be further explained by taking the embodiments shown in fig. 1 to 6 as examples:
when the protective cover 2 needs to be opened, the rear end of the cylinder is ventilated, and the piston rod extends out, so that the rotating arm 422 pushes the rotating shaft 423 to rotate, the rotating shaft 423 drives the first transmission piece 31 to rotate clockwise, and the first transmission piece 31 drives the second transmission piece 32 to move along the track of the slideway 34, thereby completing the opening of the protective cover 2. When the first transmission piece 31 rotationally contacts the limiting piece 7, the limiting position is reached, then the gas spring 6 extends out to push the first transmission piece 31 to form a locking state, so that the protective cover 2 can be stably in an opening state.
When the protective cover 2 needs to be closed, the front end of the air cylinder is ventilated, the piston rod retracts, so that the rotating arm 422 drives the rotating shaft 423 to rotate, the rotating shaft 423 drives the first transmission piece 31 to rotate anticlockwise, the first transmission piece 31 drives the second transmission piece 32 to move along the track of the slide way 34, and the protective cover 2 is closed. When the guide 33 contacts with the end of the slide 34, the second transmission member 32 cannot rotate any further, i.e. the second transmission member 32 reaches the limit position, and then the gas spring 6 extends to push the first transmission member 31 to form a locking state, so that the protecting cover 2 can be stably closed.
From this, through adopting above structure, guaranteeing that coupling 8 can normally come in and go out protector and stable realization even hang with unhook under the prerequisite, can play the guard action to coupling 8 on a relatively large scale to the hook protection dress protective scope is little and leads to the technical problem that the effect is not good among the prior art has been solved.
