When the door body 1 is closed, the upper edge of the door body 1 can abut against the lower end of the vibration reduction block, so that the vibration reduction block abuts into the accommodating groove 13, the vibration reduction spring 4 is compressed, and partial force generated when the door body 1 is closed is absorbed.
Referring to fig. 2, 3 and 4, one side of the door frame 2 close to the free end of the door body 1 is slidably connected with a mounting plate 5, the mounting plate 5 is parallel to the side edge of the door frame 2, a mounting groove 14 is formed in the door frame 2, the mounting groove 14 is parallel to the mounting plate 5, the mounting plate 5 is located in the mounting groove 14 and is slidably connected with the door frame 2, and the mounting plate 5 is accommodated through the mounting groove 14. Be equipped with damping strip 18 on the mounting panel 5, be equipped with reset spring 17 between damping strip 18 and the mounting panel 5, reset spring 17 both ends respectively with damping strip 18 and mounting panel 5 fixed connection, damping strip 18 has been close to one side of reset spring 17 and has been seted up holding tank 8 and has been held reset spring 17. One end of the damping strip 18 close to the door body 1 is designed to be wedge-shaped and faces the door body 1, so that the damping strip 18 is abutted to the door body 1 when the door body 1 is closed, and the return spring 17 is compressed, thereby absorbing the impact force generated by part of the door body 1.
Fixedly connected with stopper 12 on damping strip 18 has seted up spacing groove 11 on the door frame 2, and 11 levels in spacing groove set up, and stopper 12 is located spacing inslot 11 and door frame 2 sliding connection, carries on spacingly to damping strip 18 through stopper 12 and spacing groove 11 for damping strip 18 is along 11 horizontal slip in spacing groove. The door body 1 is located fixedly connected with gag lever post 15 in mounting groove 14, has all seted up spacing hole 16 on mounting panel 5 and the damping strip 18, and gag lever post 15 stretches into spacing downthehole 16 with mounting panel 5 and 18 sliding connection of damping strip, through setting up spacing hole 16 and gag lever post 15, carries on spacingly to mounting panel 5 for mounting panel 5 can not be crooked when sliding along mounting groove 14.
Referring to fig. 2, fig. 3 and fig. 4, racks 6 are fixedly connected to the mounting plate 5 and the vibration damping block, the racks 6 are located at adjacent ends of the mounting plate 5 and the vibration damping block, a linkage cavity is formed inside the door frame 2, the linkage cavity is located at one corner of the door frame 2, which is adjacent to the vibration damping block and the mounting plate 5, the door frame 2 is located in the linkage cavity and is rotatably connected with a gear 7, the gear 7 is engaged with the two racks 6, and the two racks 6 are vertically arranged, so that one of the racks 6 can drive the other rack 6 to move when moving, and the moving direction is vertical, and the two racks 6 are located on different planes to prevent the two racks 6 from interfering when moving. By means of the toothed rack 6 and the toothed wheel 7, the mounting plate 5 is driven to move towards the door 1 when the damping block is pressed into the receiving groove 13, so that the damping strip 18 extends out of the mounting groove 14 and abuts against the free end of the door 1.
The working principle is as follows: when the damping device is used for closing the door body 1, the upper edge of the door body 1 can be firstly abutted against the lower wedge-shaped end of the damping block, so that the damping block is extruded to move into the accommodating groove 13, and the damping spring 4 is compressed to damp the door body 1. Remove in-process spout 10 and slider 9 and carry on spacingly to the damping piece, the damping piece drives rack 6 and removes and drive gear 7 rotates, gear 7 drives rack 6 on the mounting panel 5 and removes, thereby drive mounting panel 5 moves towards one side at door body 1 place, and then make the damping strip 18 that is used reset spring 17 to connect on the mounting panel 5 stretch out mounting groove 14, the damping strip 18 after stretching out can be contradicted through the free end of wedge end AND gate body 1, thereby make reset spring 17 compressed further carry out the damping to the door body 1. The damping strip 18 in the damping device only extends out when the door body 1 is closed, the use of the door body 1 in the opening process can not be influenced, and compared with the traditional single-side damping, the damping effect is more obvious.
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.
