DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A reinforced excavator door comprises a door frame 1, wherein two opposite inner walls of the door frame 1 are provided with a rotating groove 2, wherein the two rotating grooves 2 are rotatably connected with a rotating block 3, and the two rotating blocks 3 are fixedly connected with a door body 4, so that the door body 4 can be directly supported by the door frame 1, and then the opening and closing work can be completed more stably, the two rotating grooves 2 are both T-shaped, and the two rotating blocks 3 are also T-shaped, and the shapes of the two rotating blocks 3 are matched with the two rotating grooves 2 respectively, so that the rotating support work is more stable, and a window 5 is provided on the door body 4, and a plurality of reinforcing ribs 6 are fixedly connected to one side wall of the door body 4, and the plurality of reinforcing ribs 6 are arranged directly opposite to the window 5, so that the reinforcing ribs 6 can protect the relatively weak window 5 to prevent the staff from being injured by the window 5, and two mutually distantly arranged reinforcing ribs are provided on the lower end surface of the door body 4 The auxiliary components are arranged, and the auxiliary components include an auxiliary ring 18 fixedly connected to the lower end surface of the door body 4. A plurality of spherical grooves 19 are provided on a side wall of the auxiliary ring 18 away from the door body 4. Rolling balls 20 are provided in the plurality of spherical grooves 19. The plurality of rolling balls 20 all contact the inner wall of the door frame 1. In this way, with the help of the rolling of the rolling balls 20, the door body 4 can be opened and closed more smoothly. A plurality of fixing frames 7 are provided on a side wall of the door frame 1 away from the plurality of reinforcing ribs 6. A plurality of fixing boxes 8 are fixedly connected on a side wall of the door body 4 close to the plurality of fixing frames 7. The plurality of fixing boxes 8 are matched with the plurality of fixing frames 7 respectively. A plurality of bolts 9 are slidably connected between the plurality of fixing boxes 8 and the plurality of fixing frames 7 respectively. In this way, the door frame 1 and the door body 4 can be connected and fixed at multiple positions, which greatly ensures the firmness of the door body 4 when closed, and then ensures the safety of the staff;

[0022] A control assembly is provided on the door body 4, and the control assembly includes a control cylinder 10 fixedly connected to the door body 4, a rotating shaft 11 is rotatably connected to the control cylinder 10, one end of the rotating shaft 11 is fixedly connected to a first bevel gear 12, and a plurality of second bevel gears 13 are also rotatably connected to the control cylinder 10, and the plurality of second bevel gears 13 are all meshed with the first bevel gear 12, and the plurality of second bevel gears 13 are respectively facing the plurality of fixed boxes 8, and the plurality of fixed boxes 8 are all threaded with threaded columns 14, and the plurality of threaded columns 14 are respectively rotatably connected to the plurality of door bolts 9, and the plurality of threaded columns 14 are each provided with sliding holes 15 on a side wall close to the control cylinder 10, and the plurality of sliding holes 15 are each slidably connected with sliding rods 16, and the plurality of sliding holes 15 are all square, and multiple sliding rods 16 are also square. The shapes of the multiple sliding rods 16 are matched with the multiple sliding holes 15 respectively. The sliding rods 16 set in this way cannot rotate in the sliding holes 15, and can naturally drive the threaded column 14 to rotate smoothly to complete the pushing and pulling of the door bolt 9. The multiple sliding rods 16 are respectively fixedly connected to the multiple second bevel gears 13, so that it is convenient to control the movement of multiple door bolts 9 at the same time, and then cooperate to complete the connection and fixing work between the door body 4 and the door frame 1 at multiple positions, which is convenient for the staff to operate and use. The end of the rotating shaft 11 away from the control cylinder 10 is fixedly connected with a handle 17, and the handle 17 facilitates the staff to rotate the rotating shaft 11 for adjustment.

[0023] During the use of the utility model, firstly, the staff can make the door body 4 open and close relative to the door frame 1 by means of the rotation of the two rotating blocks 3 in the rotating grooves 2. At this time, the door body 4 can be stably supported by the door frame 1 with the help of the rotating blocks 3, which greatly ensures the safety of the door body 4 opening and closing. At the same time, with the help of the rolling ball 20, the door body 4 can be opened and closed more smoothly. When the door body 4 is closed, the staff can drive the rotating shaft 11 to rotate through the handle 17, and then drive the first bevel gear 12 to drive the multiple meshing second bevel gears 13 to rotate. The multiple second bevel gears 13 can drive the corresponding sliding rods 16 to rotate, and then with the help of The auxiliary sliding hole 15 drives the corresponding threaded column 14 to rotate. Since the threaded column 14 is threadedly connected to the corresponding fixed box 8, and the sliding rod 16 is slidably connected to the sliding hole 15 without interference, the threaded column 14 can push the door bolt 9 to extend out of the fixed box 8 and insert it into the corresponding fixed frame 7. This facilitates the operation of multiple door bolts 9, greatly facilitating the use of the staff. At the same time, the door frame 1 and the door body 4 are connected and fixed from multiple positions, which greatly improves the firmness of the door body 4 and makes the internal staff safer. At the same time, the window 5 is protected by the reinforcement rib 6, which further improves the safety of the staff inside the excavator.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
