[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0023] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0024] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0025] The utility model provides an opening and closing door structure for facilitating the replacement of the tail wheel on a bucket lift. Figures 1 to 3 As shown, it includes an opening and closing door body 1 and a box body 2. The opening and closing door body 1 is rotatably mounted on the box body 2. The box body 2 is provided with an opening 21 corresponding to the tail wheel. The opening and closing door body 1 is fitted into the opening 21. A sealing member 211 is provided at the opening 21. An extension portion 11 is provided on the side of the opening and closing door body 1 facing the tail wheel. The extension portion 11 is abutted against the sealing member 211. The length and width of the extension portion 11 are respectively smaller than the length and width of the opening and closing door body 1.

[0026] In this embodiment, the box body 2 is the main part of the bucket lifting box, the opening 21 is used to provide an operating space when replacing the tail wheel, and the seal 211 is used to provide a sealing effect when the opening and closing door body 1 is closed to prevent material leakage. The extension part 11 is a protruding part of the side of the opening and closing door body 1 facing the tail wheel, and the size of the extension part 11 is set to prevent material from entering the gap when the opening and closing door body 1 and the opening 21 are closed, which can further ensure the sealing effect.

[0027] In this embodiment, the seal 211 is configured as an annular structure, and the extension portion 11 is engaged with the seal 211. The annular seal 211 can provide a continuous sealing surface to ensure that when the door is closed, the entire edge of the opening 21 can be evenly sealed. In this embodiment, the seal 211 is bonded to the inner wall of the opening 21.

[0028] It should be noted that the shape and size of the extension portion 11 need to precisely match the inner diameter and outer diameter of the annular seal 211 .

[0029] In other embodiments, in order to reduce friction and wear, a lubricant (such as silicone oil, graphite, etc.) may be applied to the contact surface between the seal 211 and the extension portion 11 , which can not only improve the sealing effect but also extend the service life of the seal 211 .

[0030] In this embodiment, a fixed plate 22 is fixedly connected to the box body 2, and a movable part 12 is fixedly connected to the opening and closing door body 1. A connecting pin 13 passes through the movable part 12. The fixed plate 22 is rotatably sleeved on the outer wall of the connecting pin 13. The movable part 12 is rotatably installed on the fixed plate 22 through the connecting pin 13, thereby realizing the rotation of the opening and closing door body 1 corresponding to the fixed plate 22, thereby ensuring the practicality of the structure.

[0031] In other embodiments, the fixing plate 22 may be fixedly connected to the box body 2 by various means such as bolts and welding.

[0032] In this embodiment, the movable part 12 includes a fixed part 121 and a rotating part 122. The fixed part 121 is fixedly connected to the top end surface of the opening and closing door body 1, and the rotating part 122 is fixedly connected to the side of the fixed part 121 away from the closing door body 1. The rotating part 122 is set to an annular structure. The maximum outer diameter of the rotating part 122 is smaller than the height of the fixed part 121, that is, the annular structure of the rotating part 122 will not exceed the height of the fixed part 121 in the vertical direction, thereby ensuring the smooth rotation of the movable part 12 and avoiding affecting the rotation opening and closing of the opening and closing door body 1.

[0033] In this embodiment, a buffer portion 14 is provided on the side of the opening and closing door body 1 opposite to the movable part 12, and the buffer portion 14 is configured as a chamfered structure. When the movable part 12 moves or rotates on the door body, the buffer portion 14 with the chamfered structure can provide a smoother contact surface, thereby reducing the direct impact of the movable part 12 on the door body and the resulting wear, and is more practical.

[0034] In this embodiment, a first mounting hole 15 is provided on the side wall of the opening and closing door body 1, and a second mounting hole 23 corresponding to the first mounting hole 15 is provided on the box body 2. Bolts are passed through the first mounting hole 15 and the second mounting hole 23, which can ensure that the connection between the opening and closing door body 1 and the box body 2 is firm and reliable when the opening and closing door body 1 is closed, and Fang Bo Ni can disassemble and install it.

[0035] In this embodiment, the door body 1 includes a support frame 16 and a door panel 17. The door panel 17 is a steel plate cut from the housing 2, and the support frame 16 is angle iron. In this embodiment, the use of angle iron as the support frame 16 ensures the stability and durability of the door. Angle iron is easy to cut, weld, and assemble, facilitating customization according to actual needs. The door panel 17 is a steel plate cut from the housing 2, fully utilizing existing materials and reducing material waste. The steel plate has high strength and good impact resistance, and as the material of the door panel 17, it can ensure the durability and safety of the door.

[0036] The utility model provides an opening and closing door structure for facilitating the replacement of the tail wheel on a bucket lift box. The opening and closing door body 1 is connected to the fixed plate 22 on the box body 2 by a movable part 12 and a connecting pin 13 to realize a rotatable installation, so that the opening and closing door body 1 can rotate around the axis of the connecting pin 13, thereby opening or closing the opening 21 on the box body 2; an annular sealing member 211 is provided at the opening 21, and when the opening and closing door is closed, the extension portion 11 is engaged with the sealing member 211 to form a continuous sealing surface, which can effectively prevent the material from leaking from the opening 21, thereby ensuring the normal operation of the bucket lift box; a buffer portion 14 is provided on the side of the opening and closing door body 1 opposite to the movable part 12, and its chamfered structure can reduce the direct impact and wear of the movable part 12 on the door body during the rotation process, thereby extending the service life of the opening and closing door; a first mounting hole 15 and a second mounting hole 23 are respectively provided on the side wall of the opening and closing door body 1 and the box body 2, and the two are connected together by bolts, which can not only ensure the firmness of the opening and closing door when closed, but also facilitate disassembly and installation.
